Underused Land

When an urban lot is left vacant, or used as a parking lot, or left with an empty building on it, or operated with a one- or two-story building when the surrounding neighborhood is five-story or ten-story buildings, all those who live or workin the area must expend their footsteps or purchased energy to get around the underused property. It isn't supplying services the neighborhood needs. Local government still pays for police and fire protection, and city water and sewer pipe goes by the property.

When a downtown acre is properly developed, ten or more acres on the fringe can be protected from premature development, and instead of sprawling or growing hopscotch into agricultural land or wilderness, the town or city can remain compact and dense.

Why do urban lots remain underused? The owner is waiting for his "ship to come in." He hopes or expects that at some point the city — his fellow taxpayers — will invest in the area, increasing his land's value and allowing him to reap a windfall gain. And as long as his property taxes are low, his holding costs are not enough to bother him. He can afford to wait. Our incentives are perverse: we don't charge him much in property taxes compared to his neighbor who has developed his land well.

How do we improve the situation? Reduce the tax rate on the buildings, and nudge it upwards on the land value. The disincentives to improving the property go down, and the incentives for either improving the land or selling it to someone who will improve it rise. Who wins? The entire neighborhood, which gets the benefit of some useful addition to the area. The environment. Those who want jobs. Those who want to open a business. Who loses? The fellow who is waiting for the rest of the neighbors to make his property valuable, or wants to leave his heirs a nice present.

Harrisburg, Pennsylvania, now taxes its land at 6 times the millage rate it taxes its buildings, and has experienced many kinds of gains as a result. Sixteen other towns and cities in Pennsylvania also tax land values more heavily than buildings, and have found it beneficial.

H.G. Brown: Significant Paragraphs from Henry George's Progress & Poverty, Chapter 4: Land Speculation Causes Reduced Wages

If the land of superior quality as to location were always fully used before land of inferior quality were resorted to, no vacant lots would be left as a city extended, nor would we find miserable shanties in the midst of costly buildings. These lots, some of them extremely valuable, are withheld from use, or from the full use to which they might be put, because their owners, not being able or not wishing to improve them, prefer, in expectation of the advance of land values, to hold them for a higher rate than could now be obtained from those willing to improve them. And, in consequence of this land being withheld from use, or from the full use of which it is capable, the margin of the city is pushed away so much farther from the center.

But when we reach the limits of the growing city the actual margin of building, which corresponds to the margin of cultivation in agriculture — we shall not find the land purchasable at its value for agricultural purposes, as it would be were rent determined simply by present requirements; but we shall find that for a long distance beyond the city, land bears a speculative value, based upon the belief that it will be required in the future for urban purposes, and that to reach the point at which land can be purchased at a price not based upon urban rent, we must go very far beyond the actual margin of urban use. ... read the whole chapter

H.G. Brown: Significant Paragraphs from Henry George's Progress & Poverty: 10. Effect of Remedy Upon Wealth Production (in the unabridged P&P: Part IX — Effects of the Remedy: Chapter 1 — Of the effect upon the production of wealth)

The elder Mirabeau, we are told, ranked the proposition of Quesnay, to substitute one single tax on rent (the impôt unique) for all other taxes, as a discovery equal in utility to the invention of writing or the substitution of the use of money for barter.

To whosoever will think over the matter, this saying will appear an evidence of penetration rather than of extravagance. The advantages which would be gained by substituting for the numerous taxes by which the public revenues are now raised, a single tax levied upon the value of land, will appear more and more important the more they are considered. ...

And will not the community gain by thus refusing to kill the goose that lays the golden eggs; by thus refraining from muzzling the ox that treadeth out the corn; by thus leaving to industry, and thrift, and skill, their natural reward, full and unimpaired? For there is to the community also a natural reward. The law of society is, each for all, as well as all for each. No one can keep to himself the good he may do, any more than he can keep the bad. Every productive enterprise, besides its return to those who undertake it, yields collateral advantages to others. If a man plant a fruit tree, his gain is that he gathers the fruit in its time and season. But in addition to his gain, there is a gain to the whole community. Others than the owner are benefited by the increased supply of fruit; the birds which it shelters fly far and wide; the rain which it helps to attract falls not alone on his field; and, even to the eye which rests upon it from a distance, it brings a sense of beauty. And so with everything else. The building of a house, a factory, a ship, or a railroad, benefits others besides those who get the direct profits. ...

And to shift the burden of taxation from production and exchange to the value or rent of land would not merely be to give new stimulus to the production of wealth; it would be to open new opportunities. For under this system no one would care to hold land unless to use it, and land now withheld from use would everywhere be thrown open to improvement.

The selling price of land would fall; land speculation would receive its death blow; land monopolization would no longer pay.* Millions and millions of acres from which settlers are now shut out by high prices would be abandoned by their present owners or sold to settlers upon nominal terms. And this not merely on the frontiers, but within what are now considered well settled districts.

* The fact that a tax on the rental value of land cannot be shifted by landowners to tenants, though recognized by all competent economists, is sometimes a stumbling block to persons untrained in economics. The reason such a tax cannot be shifted is that it cannot limit the supply of land. Landowners are presumably, before the tax is laid, charging all the rent they can get. There is nothing in a tax on the rental value of land to make tenants willing to pay more or to make land more difficult to hire. On the contrary, more land will be on the market, because of such a tax, rather than less, since the tax puts a heavy penalty on holding land out of use and unimproved for mere speculation. The competition of former vacant land speculators to get their land used will make land cheaper to rent rather than more expensive. And since only the net rent remaining after the tax is subtracted is capitalized into salable value, land will be very much cheaper to buy. H.G.B.

And it must be remembered that this would apply, not merely to agricultural land, but to all land. Mineral land would be thrown open to use, just as agricultural land; and in the heart of a city no one could afford to keep land from its most profitable use, or on the outskirts to demand more for it than the use to which it could at the time be put would warrant. Everywhere that land had attained a value, taxation, instead of operating, as now, as a fine upon improvement, would operate to force improvement. Whoever planted an orchard, or sowed a field, or built a house, or erected a manufactory, no matter how costly, would have no more to pay in taxes than if he kept so much land idle.

• The monopolist of agricultural land would be taxed as much as though his land were covered with houses and barns, with crops and with stock.
• The owner of a vacant city lot would have to pay as much for the privilege of keeping other people off of it until he wanted to use it, as his neighbor who has a fine house upon his lot.
• It would cost as much to keep a row of tumble-down shanties upon valuable land as though it were covered with a grand hotel or a pile of great warehouses filled with costly goods.

Thus, the bonus that wherever labor is most productive must now be paid before labor can be exerted would disappear.

• The farmer would not have to pay out half his means, or mortgage his labor for years, in order to obtain land to cultivate;
• the builder of a city homestead would not have to lay out as much for a small lot as for the house he puts upon it*;
• the company that proposed to erect a manufactory would not have to expend a great part of its capital for a site.
• And what would be paid from year to year to the state would be in lieu of all the taxes now levied upon improvements, machinery, and stock. ... read the whole chapter

Henry George: Why The Landowner Cannot Shift The Tax on Land Values (1887)

Charles B. Fillebrown: A Catechism of Natural Taxation, from Principles of Natural Taxation (1917)

Q41. Why would the single tax be an improvement upon present systems of taxation?
A. Because: (1) The taking for public uses of that value which justly belongs to the public is not a tax; (2) it would relieve all workers and capitalists of those taxes by which they are now unjustly burdened, and (3) it would make unprofitable the holding of land idle.

Q50. How could the landowner escape the alleged burden of an increase in his land tax?
A. Simply by assuming the legitimate role of a model landlord, by putting his land to suitable use, in providing for tenants at lowest possible price the best accommodations and facilities appropriate to the situation that money can buy.

Q52. In old cities, it is not nearly all the land in use?
A. About one half the area of New York and Chicago is classed by the assessors as vacant. In Boston the proportion is: occupied, 45 percent; vacant, 43 percent; marsh, 12 percent. ... read the whole article

Clarence Darrow: How to Abolish Unfair Taxation (1913)

The single tax theory is that the public should take all the value of land, as it was made by the public. Land value goes up because of population, and not because of the owner of the title deed, and the value should be taken by the community, and thus create a natural fund from which to make improvements for the comfort of all, and thus make life easier. It would abolish poverty, that crime of the century, which has always come with civilization; inequality of wealth, which comes as the world grows older, and which we have never been able to cure, because man wants to hold what he cannot use, and pass on to future generations what they will not use. ... read the whole speech

Upton Sinclair: The Consequences of Land Speculation are Tenantry and Debt on the Farms, and Slums and Luxury in the Cities

I know of a woman — I have never had the pleasure of making her acquaintance, because she lives in a lunatic asylum, which does not happen to be on my visiting list. This woman has been mentally incompetent from birth. She is well taken care of, because her father left her when he died the income of a large farm on the outskirts of a city. The city has since grown and the land is now worth, at conservative estimate, about twenty million dollars. It is covered with office buildings, and the greater part of the income, which cannot be spent by the woman, is piling up at compound interest. The woman enjoys good health, so she may be worth a hundred million dollars before she dies.

I choose this case because it is one about which there can be no disputing; this woman has never been able to do anything to earn that twenty million dollars. And if a visitor from Mars should come down to study the situation, which would he think was most insane, the unfortunate woman, or the society which compels thousands of people to wear themselves to death in order to pay her the income of twenty million dollars?

The fact that this woman is insane makes it easy to see that she is not entitled to the "unearned increment" of the land she owns. But how about all the other people who have bought up and are holding for speculation the most desirable land? The value of this land increases, not because of anything these owners do — not because of any useful service they render to the community — but purely because the community as a whole is crowding into that neighborhood and must have use of the land.

The speculator who bought this land thinks that he deserves the increase, because he guessed the fact that the city was going to grow that way. But it seems clear enough that his skill in guessing which way the community was going to grow, however useful that skill may be to himself, is not in any way useful to the community. The man may have planted trees, or built roads, and put in sidewalks and sewers; all that is useful work, and for that he should be paid. But should he be paid for guessing what the rest of us were going to need?

Before you answer, consider the consequences of this guessing game. The consequences of land speculation are tenantry and debt on the farms, and slums and luxury in the cities. A great part of the necessary land is held out of use, and so the value of all land continually increases, until the poor man can no longer own a home. The value of farm land also increases; so year by year more independent farmers are dispossessed, because they cannot pay interest on their mortgages. So the land becomes a place of serfdom, that land described by the poet, "where wealth accumulates and men decay." The great cities fill up with festering slums, and a small class of idle parasites are provided with enormous fortunes, which they do not have to earn, and which they cannot intelligently spend. ... read the whole article

Louis Post: Outlines of Louis F. Post's Lectures, with Illustrative Notes and Charts (1894)

d. Effect of Confiscating Rent to Private Use.

By giving Rent to individuals society ignores this most just law, 99 thereby creating social disorder and inviting social disease. Upon society alone, therefore, and not upon divine Providence which has provided bountifully, nor upon the disinherited poor, rests the responsibility for poverty and fear of poverty.

99. "Whatever dispute arouses the passions of men, the conflict is sure to rage, not so much as to the question 'Is it wise?' as to the question 'Is it right?'

"This tendency of popular discussions to take an ethical form has a cause. It springs from a law of the human mind; it rests upon a vague and instinctive recognition of what is probably the deepest truth we can grasp. That alone is wise which is just; that alone is enduring which is right. In the narrow scale of individual actions and individual life this truth may be often obscured, but in the wider field of national life it everywhere stands out.

"I bow to this arbitrament, and accept this test." — Progress and Poverty, book vii, ch. i.

The reader who has been deceived into believing that Mr. George's proposition is in any respect unjust, will find profit in a perusal of the entire chapter from which the foregoing extract is taken.

Let us try to trace the connection by means of a chart, beginning with the white spaces on page 68. As before, the first-comers take possession of the best land. But instead of leaving for others what they do not themselves need for use, as in the previous illustrations, they appropriate the whole space, using only part, but claiming ownership of the rest. We may distinguish the used part with red color, and that which is appropriated without use with blue. Thus: [chart]

But what motive is there for appropriating more of the space than is used? Simply that the appropriators may secure the pecuniary benefit of future social growth. What will enable them to secure that? Our system of confiscating Rent from the community that earns it, and giving it to land-owners who, as such, earn nothing.100

100. It is reported from Iowa that a few years ago a workman in that State saw a meteorite fall, and. securing possession of it after much digging, he was offered $105 by a college for his "find." But the owner of the land on which the meteorite fell claimed the money, and the two went to law about it. After an appeal to the highest court of the State, it was finally decided that neither by right of discovery, nor by right of labor, could the workman have the money, because the title to the meteorite was in the man who owned the land upon which it fell.

Observe the effect now upon Rent and Wages. When other men come, instead of finding half of the best land still common and free, as in the corresponding chart on page 68, they find all of it owned, and are obliged either to go upon poorer land or to buy or rent from owners of the best. How much will they pay for the best? Not more than 1, if they want it for use and not to hold for a higher price in the future, for that represents the full difference between its productiveness and the productiveness of the next best. But if the first-comers, reasoning that the next best land will soon be scarce and theirs will then rise in value, refuse to sell or to rent at that valuation, the newcomers must resort to land of the second grade, though the best be as yet only partly used. Consequently land of the first grade commands Rent before it otherwise would.

As the sellers' price, under these circumstances, is arbitrary it cannot be stated in the chart; but the buyers' price is limited by the superiority of the best land over that which can be had for nothing, and the chart may be made to show it: [chart]

And now, owing to the success of the appropriators of the best land in securing more than their fellows for the same expenditure of labor force, a rush is made for unappropriated land. It is not to use it that it is wanted, but to enable its appropriators to put Rent into their own pockets as soon as growing demand for land makes it valuable.101 We may, for illustration, suppose that all the remainder of the second space and the whole of the third are thus appropriated, and note the effect: [chart]

At this point Rent does not increase nor Wages fall, because there is no increased demand for land for use. The holding of inferior land for higher prices, when demand for use is at a standstill, is like owning lots in the moon — entertaining, perhaps, but not profitable. But let more land be needed for use, and matters promptly assume a different appearance. The new labor must either go to the space that yields but 1, or buy or rent from owners of better grades, or hire out. The effect would be the same in any case. Nobody for the given expenditure of labor force would get more than 1; the surplus of products would go to landowners as Rent, either directly in rent payments, or indirectly through lower Wages. Thus: [chart]

101. The text speaks of Rent only as a periodical or continuous payment — what would be called "ground rent." But actual or potential Rent may always be, and frequently is, capitalized for the purpose of selling the right to enjoy it, and it is to selling value that we usually refer when dealing in land.

Land which has the power of yielding Rent to its owner will have a selling value, whether it be used or not, and whether Rent is actually derived from it or not. This selling value will be the capitalization of its present or prospective power of producing Rent. In fact, much the larger proportion of laud that has a selling value is wholly or partly unused, producing no Rent at all, or less than it would if fully used. This condition is expressed in the chart by the blue color.

"The capitalized value of land is the actuarial 'discounted' value of all the net incomes which it is likely to afford, allowance being made on the one hand for all incidental expenses, including those of collecting the rents, and on the other for its mineral wealth, its capabilities of development for any kind of business, and its advantages, material, social, and aesthetic, for the purposes of residence." — Marshall's Prin., book vi, ch. ix, sec. 9.

"The value of land is commonly expressed as a certain number of times the current money rental, or in other words, a certain 'number of years' purchase' of that rental; and other things being equal, it will be the higher the more important these direct gratifications are, as well as the greater the chance that they and the money income afforded by the land will rise." — Id., note.

"Value . . . means not utility, not any quality inhering in the thing itself, but a quality which gives to the possession of a thing the power of obtaining other things, in return for it or for its use. . . Value in this sense — the usual sense — is purely relative. It exists from and is measured by the power of obtaining things for things by exchanging them. . . Utility is necessary to value, for nothing can be valuable unless it has the quality of gratifying some physical or mental desire of man, though it be but a fancy or whim. But utility of itself does not give value. . . If we ask ourselves the reason of . . . variations in . . . value . . . we see that things having some form of utility or desirability, are valuable or not valuable, as they are hard or easy to get. And if we ask further, we may see that with most of the things that have value this difficulty or ease of getting them, which determines value, depends on the amount of labor which must be expended in producing them ; i.e., bringing them into the place, form and condition in which they are desired. . . Value is simply an expression of the labor required for the production of such a thing. But there are some things as to which this is not so clear. Land is not produced by labor, yet land, irrespective of any improvements that labor has made on it, often has value. . . Yet a little examination will show that such facts are but exemplifications of the general principle, just as the rise of a balloon and the fall of a stone both exemplify the universal law of gravitation. . . The value of everything produced by labor, from a pound of chalk or a paper of pins to the elaborate structure and appurtenances of a first-class ocean steamer, is resolvable on analysis into an equivalent of the labor required to produce such a thing in form and place; while the value of things not produced by labor, but nevertheless susceptible of ownership, is in the same way resolvable into an equivalent of the labor which the ownership of such a thing enables the owner to obtain or save." — Perplexed Philosopher, ch. v.

The figure 1 in parenthesis, as an item of Rent, indicates potential Rent. Labor would give that much for the privilege of using the space, but the owners hold out for better terms; therefore neither Rent nor Wages is actually produced, though but for this both might be.

In this chart, notwithstanding that but little space is used, indicated with red, Wages are reduced to the same low point by the mere appropriation of space, indicated with blue, that they would reach if all the space above the poorest were fully used. It thereby appears that under a system which confiscates Rent to private uses, the demand for land for speculative purposes becomes so great that Wages fall to a minimum long before they would if land were appropriated only for use.

In illustrating the effect of confiscating Rent to private use we have as yet ignored the element of social growth. Let us now assume as before (page 73), that social growth increases the productive power of the given expenditure of labor force to 100 when applied to the best land, 50 when applied to the next best, 10 to the next, 3 to the next, and 1 to the poorest. Labor would not be benefited now, as it appeared to be when on page 73 we illustrated the appropriation of land for use only, although much less land is actually used. The prizes which expectation of future social growth dangles before men as the rewards of owning land, would raise demand so as to make it more than ever difficult to get land. All of the fourth grade would be taken up in expectation of future demand; and "surplus labor" would be crowded out to the open space that originally yielded nothing, but which in consequence of increased labor power now yields as much as the poorest closed space originally yielded, namely, 1 to the given expenditure of labor force.102 Wages would then be reduced to the present productiveness of the open space. Thus: [chart]

102. The paradise to which the youth of our country have so long been directed in the advice, "Go West, young man, go West," is truthfully described in "Progress and Poverty," book iv, ch. iv, as follows :

"The man who sets out from the eastern seaboard in search of the margin of cultivation, where he may obtain land without paying rent, must, like the man who swam the river to get a drink, pass for long distances through half-titled farms, and traverse vast areas of virgin soil, before he reaches the point where land can be had free of rent — i.e., by homestead entry or preemption."

If we assume that 1 for the given expenditure of labor force is the least that labor can take while exerting the same force, the downward movement of Wages will be here held in equilibrium. They cannot fall below 1; but neither can they rise above it, no matter how much productive power may increase, so long as it pays to hold land for higher values. Some laborers would continually be pushed back to land which increased productive power would have brought up in productiveness from 0 to 1, and by perpetual competition for work would so regulate the labor market that the given expenditure of labor force, however much it produced, could nowhere secure more than 1 in Wages.103 And this tendency would persist until some labor was forced upon land which, despite increase in productive power, would not yield the accustomed living without increase of labor force. Competition for work would then compel all laborers to increase their expenditure of labor force, and to do it over and over again as progress went on and lower and lower grades of land were monopolized, until human endurance could go no further.104 Either that, or they would be obliged to adapt themselves to a lower scale of living.105

103. Henry Fawcett, in his work on "Political Economy," book ii, ch. iii, observes with reference to improvements in agricultural implements which diminish the expense of cultivation, that they do not increase the profits of the farmer or the wages of his laborers, but that "the landlord will receive in addition to the rent already paid to him, all that is saved in the expense of cultivation." This is true not alone of improvements in agriculture, but also of improvements in all other branches of industry.

104. "The cause which limits speculation in commodities, the tendency of increasing price to draw forth additional supplies, cannot limit the speculative advance in land values, as land is a fixed quantity, which human agency can neither increase nor diminish; but there is nevertheless a limit to the price of land, in the minimum required by labor and capital as the condition of engaging in production. If it were possible to continuously reduce wages until zero were reached, it would be possible to continuously increase rent until it swallowed up the whole produce. But as wages cannot be permanently reduced below the point at which laborers will consent to work and reproduce, nor interest below the point at which capital will be devoted to production, there is a limit which restrains the speculative advance of rent. Hence, speculation cannot have the same scope to advance rent in countries where wages and interest are already near the minimum, as in countries where they are considerably above it. Yet that there is in all progressive countries a constant tendency in the speculative advance of rent to overpass the limit where production would cease, is, I think, shown by recurring seasons of industrial paralysis." — Progress and Poverty, book iv, ch. iv.

105. As Puck once put it, "the man who makes two blades of grass to grow where but one grew before, must not be surprised when ordered to 'keep off the grass.' "

They in fact do both, and the incidental disturbances of general readjustment are what we call "hard times." 106 These culminate in forcing unused land into the market, thereby reducing Rent and reviving industry. Thus increase of labor force, a lowering of the scale of living, and depression of Rent, co-operate to bring on what we call "good times." But no sooner do "good times" return than renewed demands for land set in, Rent rises again, Wages fall again, and "hard times" duly reappear. The end of every period of "hard times" finds Rent higher and Wages lower than at the end of the previous period.107

106. "That a speculative advance in rent or land values invariably precedes each of these seasons of industrial depression is everywhere clear. That they bear to each other the relation of cause and effect, is obvious to whoever considers the necessary relation between land and labor." — Progress and Poverty, book v, ch. i.

107. What are called "good times" reach a point at which an upward land market sets in. From that point there is a downward tendency of wages (or a rise in the cost of living, which is the same thing) in all departments of labor and with all grades of laborers. This tendency continues until the fictitious values of land give way. So long as the tendency is felt only by that class which is hired for wages, it is poverty merely; when the same tendency is felt by the class of labor that is distinguished as "the business interests of the country," it is "hard times." And "hard times" are periodical because land values, by falling, allow "good times " to set it, and by rising with "good times" bring "hard times" on again. The effect of "hard times" may be overcome, without much, if any, fall in land values, by sufficient increase in productive power to overtake the fictitious value of land.

The dishonest and disorderly system under which society confiscates Rent from common to individual uses, produces this result. That maladjustment is the fundamental cause of poverty. And progress, so long as the maladjustment continues, instead of tending to remove poverty as naturally it should, actually generates and intensifies it. Poverty persists with increase of productive power because land values, when Rent is privately appropriated, tend to even greater increase. There can be but one outcome if this continues: for individuals suffering and degradation, and for society destruction. ...

Q32. Is not ownership of land necessary to induce its improvement? Does not history show that private ownership is a step in advance of common ownership?
A. No. Private use was doubtless a step in advance of common use. And because private use seems to us to have been brought about under the institution of private ownership, private ownership appears to the superficial to have been the real advance. But a little observation and reflection will remove that impression. Private ownership of land is not necessary to its private use. And so far from inducing improvement, private ownership retards it. When a man owns land he may accumulate wealth by doing nothing with the land, simply allowing the community to increase its value while he pays a merely nominal tax, upon the plea that he gets no income from the property. But when the possessor has to pay the value of his land every year, as he would have to under the single tax, and as ground renters do now, he must improve his holding in order to profit by it. Private possession of land, without profit except from use, promotes improvement; private ownership, with profit regardless of use, retards improvement. Every city in the world, in its vacant lots, offers proof of the statement. It is the lots that are owned, and not those that are held upon ground-lease, that remain vacant.

Q44. Though some people have made money by owning land, isn't it true that others have lost? And don't the losses more than off-set the gains?
A. Possibly. But that has no bearing upon the question. What men lose through investments in land, the community does not gain; but what they gain the community does lose. Therefore, as between land speculators and the community, the losses cannot be charged against the gains.

Q46. How can it be possible that speculative land values cause business depressions when, as any business man will tell you, the whole item of land value — whether ground rent or interest on purchase money — is one of the smallest items in every business?
A. You overlook the fact that the item of speculative rent is the only item which the business man does not get back again. The cost of his goods, the expense of clerk hire, the rent of his building, the wear and tear of implements, are all received back, in the course of normal business, in the prices of his goods. Even his ground rent, to the extent that it is normal (i.e., what it would be if the supply of land were determined alone by land in use, and not affected by the land that is held out of use for higher values), comes back to him in the sense that his aggregate profits are that much greater than they would be where ground rent was less. But the extra ground rent which he is obliged to pay, in consequence of the abnormal scarcity of land, is a dead weight; it does not come back to him. Therefore, even if infinitesimal in amount, as compared with the other expenses of his business — and that is by no means admitted — it is the one expense which may break a thriving business down. Besides, it is not alone the ground rent paid by the business man for his location that bears down upon his business prosperity; the weight of abnormally high land values in general presses upon business in general, and by obstructing the flow of trade forces the weaker business units to the wall. It is not altogether safe to deduce general economic principles from the ledgers of particular business houses.

Q59. How would you compensate the man who has bought a lot in order to make a home upon it, but is not yet able to build?
A. By letting him, when he is ready to build, have a better lot for nothing. The single tax would do this by discouraging the cornering of land which now makes all good lots scarce. When land was no longer appropriated except for use, and that would result from the operation of the single tax, there would be an abundance of building lots to be had for the taking, which would be far more desirable than the kind to which men who cannot afford to build homes now resort when they buy lots for a home. ... read the book

Charles T. Root — Not a Single Tax! (1925)

... But before this time the reader, unless he has given previous attention to the subject, is full of objections to the above doctrine: "How about the law?" he is asking. "Hasn't a man the right to buy a piece of land as cheaply as he can, to do what he pleases with it, and hold on to it till he gets ready to sell?" The answer is that at present he certainly has this statutory right, which has been so long and so universally recognized that most people suppose it to be not only a legal, but a real or equitable right. A shrewd man, foreseeing the direction of growth of population in a city, for example, can buy a well-located block at a moderate figure from some less far-seeing owner, can let it grow up to weeds, fence it off against all comers and give it no further attention except to pay the very small tax usually imposed upon vacant land.

Meantime the increasing community builds up all around it with homes, banks, stores, churches, schools, paving and lighting the streets, giving police and fire protection, etc., and at last comes to need this block so urgently that the owner is fairly begged to sell it, at three or ten or fifty times what it cost him. Quite often the purchaser at this enormous advance is the very community which has through its presence and the expenditure of its taxes created practically the whole value of the land in question!

It was said above that an individual has a statutory right to pursue this very common course. That was an error. The statement should have been that he has a statutory wrong; for no disinterested person can follow the course of land speculation as almost universally practiced, without feeling its rank injustice. ...

An illustration has already been given of the case of a piece of farm land. Let us take an example in a large city. Let us take a corner lot centrally located in New York City, the title to which lot is held by, say, Mr. John William Rhinelastor. This lot was a part of an old Dutch farm, and is an heirloom. It did not cost the present owner anything, nor his father nor his grandfather. There is a little old building on it, which has always been rented at a figure ten times as large as the taxes imposed, so that the owner has been handsomely subsidized each year for storing his title-deeds during a period of the city's growth in which the increase in population and the expenditure of public money in that neighborhood have raised the value of this corner location to, say, two hundred times its early value.

About now, Mr. Rhinelastor decides that he will go abroad to live, and can't be bothered with this piece of property. But knowing that the pressure of population is sure to increase and that the expenditure of public money to the benefit of this land must continue, he will not sell it. So he gives a twenty-one year lease to the corner for, say, $20,000 a year net, with a privilege to the lessee of renewals at advancing figures. The lessee agrees to pay all taxes.

Now what is this net $20,000 a year, which will be regularly remitted to Mr. Rhinelastor, in Europe or wherever he may be, given in payment for? Not for the old building — the first thing the lessee does is to pull it down. Not for the land itself — it is all rock, which has got to be blasted out as part of its improvement.

Clearly it is paid for a location or site value, which the community, and the community only, has built up and paid for. In other words, the present $20,000 rental, and the larger one which that location will command in later years, is strictly a community product, and as such belongs to the community and not to Mr. Rhinelastor. ...

Again, while it must be firmly insisted that the economic rent is the rightful property of the community and not of the landowner, the community would probably never take it all. Communal ownership of land is not desirable, even if it were practicable. Individual ownership and management are best, and it is not at all improper for the community to allow the owner something for caring for the land to which he holds title, and for collecting and transmitting to the treasury the economic rent.

But — and right here is one of the prime advantages of the abolition of taxation — Mr. Rhinelastor, in order to get satisfactory return from his land, must improve it. Unless he is satisfied with a small income from it, to wit, the proportion of the economic rent which the community chooses to leave in his hands, he must put upon his land the best building the location will warrant. The rents of this building will be his in their entirety, not one dollar of them being taken from him by taxation. If he is not prepared or not willing to do this he would probably find it more profitable, before he leaves the country, to sell the land to some one of the many persons who are eager to build upon it. It will always be salable, although not by any means at present figures.

Now imagine for a moment the effect upon the appearance of a city and upon the comfort of its population which would result from the change of fiscal policy which this article proposes. At present, a tempting premium is placed upon keeping land unimproved or inadequately improved, while a heavy penalty is imposed upon improvement. Most land appreciates constantly. All buildings depreciate from the moment of completion. Yet the building is taxed equally with the land.

What incentive does such a system offer the speculative landowner to put up a commodious, well-lighted modern structure in place of the old ruin which now pays him so well? The old one cannot depreciate much more, and while paying a trifling tax because of its physical worthlessness, he is thereby enabled to collect and pocket the economic rent of the ground, which the community is continually rendering more valuable. The new building would absorb a large amount of capital, would begin to run down even before it could be occupied, and would be taxed to the limit. Why then is not the landlord justified in letting well enough alone, enjoying the growing economic rent, and waiting till he can get a fancy price for the right to collect it?

But reverse the conditions. Reclaim for the community its natural income, making it expensive either to keep needed land vacant or to withhold it from the ready and willing to improve it to the full extent of its possibilities.

Does it require severe intellectual effort to foresee the results? Better and better houses, apartments, tenements, offices and stores, more employment for labor in all enterprises now held back by the shadow of the tax-gatherer, an end of all tax-lying, tax-evasion and tax-injustice, and withal, a public revenue adequate to all real public needs.

What a contrast to the existing plan of pouring public money into the laps of individual landowners to their own moral disadvantage and that of their children, as well as the economic disadvantage of their neighbors, while constantly cudgeling the civic brains, straining the public credit, impoverishing widows and orphans, and increasing the exactions from every citizen and corporation that can be caught, in the effort to raise more and more money to bestow upon the same beneficiaries. ... read the whole article

Bill Batt: Painless Taxation

Abstract
Real tax reform could do away with those taxes that are resented by the large proportion of our population. We could replace all taxes on wages and on interest by instead taxing economic rent. Rent is windfall income; it is income that arises not from the efforts of any person or corporation; it comes about as a surplus gain from common social enterprise. There is ample moral warrant for society to lay claim to that which it has created, as well as to that which no individual or party has earned. Analysis increasingly makes clear that economic rent in all its forms is far larger than official government figures indicate; in fact it is likely sufficient to supplant all current taxes on labor and capital (wages and interest) which are acknowledged to have so many negative effects. Recovering economic rent in all its manifestations by taxing its various bases actually can foster economic performance and yield other benefits that make it the natural source of revenue for governments. Such a tax is essentially painless. ...

The Possibility of Land (Rent) Taxation

The key to understanding how taxing various forms of land conform to sound tax theory comes with an appreciation of the importance of economic rent. Largely discarded in 20th century economic analysis, rent is the price for the use of land. Just as the price of labor is paid in wages and the price of capital is paid in interest, land rent is the unearned increment that attaches to land in the form of a surplus when its price is not paid by its users. All taxes, ultimately, come out of rent; however, by collecting revenue from other sources, the rent is left to settle in ever increasing encrustations on land sites, i.e., capitalized, ultimately raising their market price. In so doing, these land prices are distorted so that their optimal use is not secured.

Examples of such distortion are not difficult to identify. Consider, first of all, the use of locations in our urban environments, many of which are underused while prospective entrepreneurs are driven to second-best locations because titleholders opt to let the rent accrete and passively raise their market price. Land speculation is rife most of all in instances where there is a great disparity between the tax rate on these sites and the rate of rent appreciation. When the holding costs of ownership are nominal, there is no incentive for improving them or selling to others who will, and urban environments suffer as a result. Another example is rent that collects to the electromagnetic spectrum, making it attractive for owners of electronic media, communications networks and so on, to rely on returns to their investments even when the resource itself is sparsely used. So also with the time slots for take-offs and landings at airports. These opportunities are respected as private property, even while they gain in market value in response to the general traffic volume of the facility. This occurs regardless whether the particular airlines use their slots or not. London Mayor Ken Livingstone has proposed to tax the rent from Heathrow and Gatwick both for their revenue advantage and to assure their more optimal use.[7] One could go on, pointing to any number of instances where economic rent is available to be had for the support of public services in lieu of conventional taxes which we recognize as destructive in their effects.[8] It is not surprising that when pressed even conventional (neoclassical) economists are often willing to concede that the best possible tax of all is one placed on land rent.[9] ... read the whole article

Jeff Smith and Kris Nelson: Giving Life to the Property Tax Shift (PTS)

Lindy Davies: Land and Justice

If we just look at the "ecological footprint," it's easy to be scared of the seemingly unavoidable damage we are doing to the earth. But seeing "the footprint" in terms of its components — subsistence, wealth, and illth — makes it clear that the fact of persistent and growing global poverty is not the inevitable result of population growth. I believe it’s true that the world cannot long support current levels of pollution, waste and habitat destruction — but these problems spring not from production itself — and certainly not from trade, itself — but from privileges, granted to individuals and corporations — things that we can correct, if we choose to.

To solve the problem of land and justice is to remove unjust privilege, by instituting an economic system that rewards production and prohibits extortion.

It’s all about the land: not only is land necessary for all life — land is also necessary for all production. So, as human population increases, and as the production of wealth gets more and more efficient, the demand for land goes up, and, of course, the land factories start cranking out more land!

Wait! They can't DO that, can they?

Wealth — products, widgets — these things are made by human beings. If customers are willing to buy more of them, then manufacturers will make more of them. But human beings can't make land. The supply of land cannot be increased. If the demand for land increases, only one thing can happen: its price will go up.

The owners of land see population and production go up, up, up — and no more land. So, they will only put their land to use if they have an immediate need for the cash. If they can afford to wait, they will wait, because they expect the land's value to increase with time.

That, in a nutshell, is the key to the land problem — the problem of poverty.

That is why millions upon millions of people who are willing and able to work cannot find work, even while millions upon millions of acres of useable land (city land, industrial land, farm land, you name it) are held idle.

This leads to no end of problems. In the United States, it brings urban blight and suburban sprawl, which disrupt communities, and waste energy and resources. You don’t think under-use of land is that big a deal? Consider the fact that in the five boroughs of New York City, 7.5% of its land, or 18.6 square miles, is vacant. That’s buildable land, not parks or streets. And, of course, a great deal more land in New York, as in every other city, is used somewhat, but far less than the local economy would support. New York City has about 80 people per acre of residential land. That means that New York’s vacant land could house another 956,000 people at current density levels, without even starting to use its vast stock of under-used land. ... read the whole speech

Tony Vickers: From Zee to Vee: using property tax assessments to monitor the economic landscape

Land comprises all natural resources, not just ‘terra firma.’ It is the universe minus man’s products. Even the simplest of human activities, sleep, requires each of us to occupy exclusively a space, a location, preferably a bed in a home of our own. But that word ‘own’ conjures emotions and political postures. ...

The author came to this field of work from a career in defence mapping, where he dealt with a wide range of applications for GIS using geospatial physical map data of variable quality from/of many countries and sources. Prior to that he was a construction engineer and planner with several firms in England generically known as ‘speculative developers’. Their core business, he learned from experience, was not necessarily to create homes, office blocks and factories but to manipulate the property market in order to profit from the uplift in land values that follows from decisions by public officials and other entrepreneurs. His on-site construction management skills were needed to produce a steady turnover, employ a minimum of labour and capital and minimise inevitable losses on operations. The real profits were made on land deals, buying speculatively and holding sites out of use until ‘ripe’ for development. ...

Distinguishing land from buildings

The Nobel-winning economist William Vickrey said that the property tax is actually two different taxes (Vickrey 1991). That is because buildings are capital, not land, in the economic sense – even if, in most legal codes, there is no distinction between land and improvements made to it which are all lumped together as ‘landed property’ or real estate. Buildings and other improvements to land all depreciate over time unless further capital is expended. Eventually the market value of such improvements may become negative, owing to the costs that would need to be incurred by someone wishing to redevelop the site for an alternative use. But that does not necessarily take away the rental value of the site.

Much urban blight is caused by these so-called ‘brown field’ vacant and under-used sites. However they are often in valuable locations, with good transport connections. It may be that owners are speculating that land prices will rise and enable them to sell at greater profit in the future than now, or it may be that there is genuinely no market for sites in a particular location unless the cost of remediation is subsidised as a form of public investment. Such investment, according to Vickrey and other followers of Henry George, can be entirely funded from LVT. In a lecture given in 1991, first published last year, Vickrey claimed:

“Cities have the capacity to be fully self-financing without dependence on either federal assistance or on general taxes that are unrelated to benefits received.”

The proviso, according to Vickrey, is to replace the tax on buildings with a tax on land value alone – LVT:-

“The property tax combines one of the best and one of the worst taxes we have. The portion that falls on sites or land values is the only major tax that is reasonably free of distortionary effects and is not intolerably regressive”.

Taxing buildings and work done to improve them discourages such work. Un-taxing them and taxing land more highly, irrespective of its actual state of development but based upon its highest and best immediate potential use, will encourage owners to maintain their sites and buildings in such a way as to maximise their income. A remote site or one with conservation or other restrictions will have a low site value, hence attract low taxes, whereas a high value city centre derelict site will very soon be redeveloped. The extra property tax revenue from extending the tax base to sites that are currently under-taxed (because the tax is based primarily on building/rental value not site/owner value), ensures public infrastructure projects can be funded without resource to general taxes or excessive borrowing on the financial markets.Read the whole article

• the limited supply and "natural" productivity of the soil and natural resources,
• the publicly provided services, including planning, improvements that increase the market value of land and
• the growth of communities and peoples' competitive demand for the exclusive use of prime locations.

The collection of land rent should be used as revenue, by the community for supplying public needs. This returns the advantage an individual land possessor receives from the exclusive use of a land site, to the balance of the people who live within the community and have allowed the land possessor the exclusive use of the land site for the period of time.

By prohibiting people from using good land, the possessors force the premature use of other less desirable land, which is more distant from the city. This raises the cost of community improvements and the rental value of the unused, but better located, land. This precipitates the degradation of the rural environment by using city land inefficiently -- and creates huge unnecessary pressures on the natural environment.

A problem that we face is that cities throughout the world are spreading out and using land prematurely which is not needed and should not be used. That is because failure to collect land rent subsidizes the waste of natural resources and clutters the environment. Cities that collect the full rental value of land are more compact and provide greater and less costly amenities for their citizens.

Any moves to enact good government principles without collecting the full market rent of the land may result in a failure. People are guided by the profit motive. When people can make a larger profit by doing nothing, but keeping the land they possess out of use for a long period of time, they will do so. When the community collects the full market rent of land, they eliminate the motive for keeping land out of efficient use, because the unearned profit has been collected as public revenue.

Efficient land use appeals to all people because it surpasses the political constraints of most people. Everybody understands that the earth belongs equally to all people. They want a clean environment on earth and to leave a healthy inheritance to the future generations, regardless of their political viewpoints.

The major function of a competent city government is to provide good community services by collecting the land rent created within the community to ensure the efficient use of land and equal opportunities for all of its citizens. Transportation is an important function of government which would facilitate the creation of a compact city, where people can easily find the facilities they desire for education, commerce, religion and recreation. Good land use, with the freedom of individuals to achieve the highest and best use of land, would ensure a desirable community. A compact city would reduce the need to invade the wilderness and devastate the environment.  ... Read the whole article

PROPERTY IS APPRAISED in two ways. Both start by estimating its market value.

• The land-residual approach subtracts the value of buildings from this overall value, designating the remainder as the value of land. Building values may be estimated in terms of their replacement cost (which usually produces a very high estimate, leaving little land value) or their depreciated value (which gives an unrealistically low building estimate, inasmuch as maintenance and repairs save most buildings from deteriorating through wear and tear). Using the depreciated value method leaves a higher residual land value. The Federal Reserve Board recently has experimented with a hybrid intermediate method that values buildings on the basis of their "historical costs".
• The building-residual approach starts by valuing the land, and treats the difference as representing the building's value. The first step in this approach is to construct a land-value map for the district or city. This displays fairly smooth contours for land values. Overlays would show zoning variations. Most of the variations in property prices around this normalized map will be for structures, along with a sizable component of "errors and omissions." This approach rarely is used, and most assessed land values vary drastically from one parcel to the next. The problem is especially apparent in the case of parking lots or one-story "taxpayers," that is, inexpensive buildings in neighbourhoods that are heavily built up. Their purpose is simply to be rented out at enough to carry the property's tax bill, not to maximise the site's current economic value.

Note that the Fed's land-residual appraisal methods do not acknowledge the possibility that the land itself may be rising in price. Site values appear as the passive derivative, not as the driving force. Yet low-rise or vacant land sites tend to appreciate as much as (or in many cases, even more than) the improved properties around them. Hence this price appreciation cannot be attributed to rising construction costs. If every property in the country were built last year, the problem would be simple enough. The land acquisition prices and construction costs would be recorded, adding up to the property's value. But many structures were erected as long ago as the 19th century. How do we decide how much their value has changed in comparison to the property's overall value?

The Federal Reserve multiplies the building's original cost by the rise in the construction price index since its completion. The implication is that when a property is sold at a higher price (which usually happens), it is because the building itself has risen in value, not the land site. However, if the property must be sold at a lower price, falling land prices are blamed.

If it is agreed that any explanation of land/building relations should be symmetrical through boom and bust periods alike, then the same appraisal methodology should be able to explain the decline of property values as well as their rise. The methodology should be as uniform and homogeneous as possible. By that, I mean that similar land should be valued at a homogeneous price, and buildings of equivalent worth should be valued accordingly.

If these two criteria are accepted, then I believe that economists would treat buildings as the residual, not the land. Yet just the opposite usually is done. ...

For hundreds of years property's value has been calculated by discounting its flow of rental income at the going rate of interest. The lower the interest rate, the higher the price a given rental stream will justify -- or as property owners express it, the more years' rent a property will bring. What is so striking about land values today is that they are rising for reasons independent of their earnings stream. The major new consideration is their prospect for future "capital" (that is, land-price) gains. In sum, the ultimate aim of real estate investors no longer is so much to seek income -- most of which is pledged to their bankers as interest payments on the property they acquire -- as much as to seek property gains. Politically opportunites abound. Merely changing zoning in New York City in the 1980s to allow using commercial loft spaces for residential purposes had the effect of multiplying asset values five or tenfold.

Whether the gains come from selling the property or from borrowing more money against it, the essential phenomenon is the rapid growth in asset values and real estate's uniquely favored tax treatment. That's why investors choose real estate instead of bonds or stocks, and much of the strategy underlying corporate takeovers has followed the strategies they developed over the past half century.

Nationwide the capital-gains dimension needs to be incorporated into the rental revenue statistics to measure real estate's total returns. This sector's nearly complete success in escaping the tax collector has placed an enormous tax burden on everyone else. read the entire article

One example that I know is that of a friend who bought land within the city but did nothing with it. I asked him why he put good money into an investment that had no visible return? He replied that, by holding the land for future sale or development, his long term return, in capital gains would exceed 18% annually. If he built a building on the site now, his long term return would only be 12% annually, including both net income plus capital gains. Why should he use his land now when it would be more profitable for him to not use it, but to hold it for a larger future gain?

Most major cities have a substantial amount of fully serviced but unused or underused land sites. It is estimated that 38% of the land area in Los Angeles is unused, 30% in New York City and 25% in Washington, D.C. Intercity sites are bypassed because land speculators receive a greater benefit by ignoring the highest and best use of land sites. A greater profit is made when development is delayed and the land price increases to higher levels. But building within existing developed areas uses the existing and underused infrastructure, roads, transit, public facilities, and services. Sprawl requires new expenditures on public goods and services, more government, more taxes, more dislocation.  ... Read the whole article

Mason Gaffney: The Taxable Surplus of Land: Measuring, Guarding and Gathering It

Al Hartheimer: Affordable Housing and the Land Value Tax Perspective: a letter to Asheville, North Carolina

To make housing more affordable we advocate the reduction of the tax on buildings and a simultaneous rise of the tax on land to yield the same or more revenue. This is called Land Value Taxation. It is also called the two-rate tax, incentive taxation and the split-rate tax.

We know, from studies of the twenty Pennsylvania taxing jurisdictions that use LVT, that every time the tax on buildings is reduced, and simultaneously the tax on land is increased, that there is a spurt of construction. According to Plassmann and Tideman (A Markov Chain Monte Carlo Analysis of the Effects of Two-Rate Property Taxes in Pennsylvania, Florenz Plassmann and T. Nicholas Tideman, September 1997, p19), "This means that, for an average municipality, an increase in the adjusted tax differential of 1 mil will yield an expected increase in the total value of construction of 1.58%". Much of this increase in construction comes from people improving their homes with the knowledge that the penalty for making improvements is being reduced.

Does this provide more affordable housing? Pittsburgh has used the two-rate tax since 1915, 85 years. Recently, Lew Sichelman (The Housing Scene, by Lew Sichelman, the Los Angeles Times, Sunday, June 4, 2000) said "According to the federal government's latest tabulation, the average of both new and existing houses sold in 31 key markets nationwide reached $200,300 during the first three months of this year…. The San Francisco Bay Area…remains the most expensive place in the country in which to buy a house. The average price there is now $384,700. …At the other end of the price spectrum, the average remains under $150,000 in only two places: Pittsburgh at $143,300….and St. Louis at $145,100." So Pittsburgh, the only sizeable city in the United States to use the two-rate tax, has the lowest cost housing in the country. A coincidence? Perhaps not.

An interesting and amazing thing about the Pittsburgh experience is that the two-rate tax in Pittsburgh applies only to the city tax, not to the school tax and not to the county tax. It's impressive to say that for the city tax the tax rate on land is six times higher than the tax rate on buildings, but because of the much higher value of buildings, only about 57% of the city tax is from land. When you add the school tax and the county tax, less than 40% of the tax yield is from land.

So a modest land tax applied over a long time (85 years) results in the lowest average cost of housing in the country. Imagine what would happen if the tax on buildings were eliminated and all of the city revenue came from the land tax. It boggles the mind to think about it. ... read the entire article

Jeff Smith: Sharing Natural Rents to Sustain Human Society

Transportation - Cars vs. a Mix of Modes

• Rent. Not having to pay Rent to their community, urban owners awaiting a higher future return under-use prime sites, forcing development outward. Sprawl requires cars, displacing buses, bikes, and people.
• Taxes. The tax on income makes capital less remunerative, so a blue chip stock, not quite so visionary, becomes more attractive than a risky new start-up trying to make money doing good. A hybrid electric car or a fuel-cell light enough to power buses and trucks begs for funds while a GM doesn't. Tariffs fall on imported vehicles, which tend to be more fuel-efficient than their domestic counterparts. Thus the market share of efficient cars is kept smaller than it otherwise would be.
• License. The price of gasoline does not include all the costs from smog - damage to crops, lungs, buildings, etc - disadvantaging bikes and buses.
• Subsidy. Freeways, overly wide streets, highway patrols, traffic courts, ambulances, and free military chastisement of overseas suppliers that everyone pays for, not just drivers, pave the way for car dependency, not an integrated use of bikes and buses. Gasoline ought to cost at least $7.00 per gallon figures the World Resources Institute (Green Fees, 1992). ...

Henry David Thoreau said the best thing government can do for business is get out of it. Nevertheless, some hope to shift subsidies from grey bads to green goods. Yet the state need not subsidize at all. It's dauntingly difficult to know whom to fund; a solar steam generator may be the most promising idea one day while photovoltaics are the next. Efficient alternatives don't need largesse but fairness. A handout shields new industry from the forces that compel efficient growth. The best thing government can do for the environment is exit environmental enterprise. ... read the whole article

Land value taxation generalizes into the principle that people should pay for all of their appropriations of natural opportunities, according to the opportunity costs of those appropriations, and the resulting revenue should be shared equally. ...

Taxing land has an additional effect that increases the stock of capital. A tax on land represents a redistribution from living adults to the young and unborn, who will now be born with rights to land. Unless there is a perfectly offsetting reduction in the desire to accumulate assets to transfer to the next generation, this redistribution will induce the living, who now have fewer assets, to accumulate at a more rapid rate than they would otherwise do. That is, saving and capital accumulation will increase.

Taxing land also increases the efficiency with which land is used. This occurs through three paths.

• First, a tax on land reduces the return to land speculation, and therefore reduces the quantity of land speculation.
• Second, as taxes on land are capitalized into the selling price of land, the result is the substitution of a recurring cost (the annual tax) for a one-time cost (the purchase price). This makes land relatively more attractive to bidders with high discount rates and relatively less attractive to bidders with low discount rates. To the extent that the former are more entrepreneurial and the latter more passive investors, land will tend to flow into the hands of persons who will choose to use it more intensively.
• The third path by which a tax on land increases the efficiency with which land is used is that, for those who are using land inefficiently, it substitutes an explicit cost (the tax) for an implicit one (the income foregone by inefficient use).

Psychologically, explicit costs tend to be more effective in motivating efficient behavior than implicit ones. ... read the whole article
