Essentials of Economic Theory Part 2

Wealth consists of effectively useful concrete things regarded either as particular articles that can be identified and watched till they perish in the using, or as an abiding stock of articles of this genus, each one of which has in itself only a transient existence. See an article on "The Wealth Concept," by Professor Charles A. Tuttle, in the _Annals of the American Academy of Political and Social Science_, for April, 1891, and other articles by the same author.

_Labor as a Permanent Ent.i.ty._--The term _labor_ is sometimes used to describe a permanent aggregation of laborers no one of whom lives and works through more than a brief period. Labor is thus a.n.a.logous to capital and laborers to capital goods. A permanent working force is composed of perishable beings as a permanent producing fund is composed of perishable goods. Both are commonly described by the use of abstract terms, but both are in reality concrete things; and actually to reduce either to a mere abstraction would be to put a material ent.i.ty out of existence. We instinctively speak of a value--a given number of dollars--in describing a man's capital, but it is dollars "invested in" productive instruments; and we instinctively speak of labor when we mean an abiding force of workingmen. Neither capital nor labor is like an immaterial soul that can live apart from its body. Each consists of a permanent body with a shifting composition. A permanent sum, on the one hand, a permanent amount of working energy, on the other, are always present, but they are in goods and men respectively. Each may well be described by the use of an abstract term, and in practical life it commonly is so; but it is a concrete reality.

_Peculiarity of Land as a Capital Good._--One reservation needs to be made when we call capital goods perishable. If we include land under this term, we must make it an exception to the rule of destructibility. It is the only thing that does not go out of existence in the using. It is not a produced good at all and does not stand, like other goods, in an intermediate position between labor and the gratification that labor is intended to produce. Work did not create it and using will not end it. It will be called, in our study, a capital good, for it is a form of wealth which produces other wealth. It enters into the permanent productive fund that society is using.

_Differences between Land and Other Capital Goods Important in Economic Dynamics._--It is in a later part of the study which deals with economic changes--the part which we shall call Economic Dynamics--that the differences between land and artificially made goods become prominent, and these differences will receive due emphasis in their proper place. In studying the law which would govern economic society if no essential economic changes were taking place,--in reducing society, as it were, to a static state,--we find that there is a certain set of characteristics which land shares with those capital goods which are the products of human industry. In static studies it is best to group the productive instruments which men make with the one unmade good which nature furnishes and to recognize that together they embody the permanent fund of productive wealth.[4]

[4] What is commonly termed land contains elements which perish in the using. Such are deposits of coal, ores, or oil, and those ingredients of loam which are exhausted by tillage.

Such elements of the soil are not land in the economic sense.

How they should be regarded will be shown in a later chapter.

_Mobility an Attribute of Capital._--Even in a static society capital would be permanent, while particular capital goods would be perishable. In dynamic studies another quality of capital, as distinguished from capital goods, comes into the foreground, namely, mobility. It is the power to move without loss from one industry to another. Goods cannot be thus moved with any freedom. A loom cannot be taken out of a woolen mill and made to do duty in a carpenter's shop, nor can a circular saw be made available in weaving. When the loom wears out and needs replacement, it is in the owner's power to procure either another loom or a circular saw, and if he chooses the latter alternative, he causes capital to move into the woodworking business.

A whaling ship would not be useful as a cotton mill; but much capital that was once invested in the whale fishery of New England has since found its way into manufacturing. The transfer can often be made without waste. If the earnings of an instrument have sufficed to replace it with another that is like it, they may suffice for producing an instrument that is unlike it. Waste, if it occurs, results from a failure of the original instrument to earn the fund for replacement. Capital which thus abides but pa.s.ses from one employment to another is a body the ident.i.ty and the character of whose component parts change. The transfer of capital from one industry to another is a dynamic phenomenon which is later to be considered. What is here important is the fact that it is in the main accomplished without entailing transfers of capital goods. An instrument wears itself out in one industry, and instead of being succeeded by a like instrument in the same industry, it is succeeded by one of a different kind which is used in a different branch of production. Goods have not moved from one branch to another, but capital has done so.

_How Capital itself may be Destroyed._--When we speak of capital as permanent, we mean that using does not destroy it as it destroys the tissues of which it is composed. Fires, earthquakes, and business disasters put parts of it out of existence and affect the volume of the fund as a whole; but production itself leaves it intact. It is this very production which destroys capital goods and makes it necessary to replace them.

CHAPTER III

THE MEASURE OF CONSUMERS' WEALTH

In all stages of social development the economic motives that actuate men remain essentially the same. All men seek to get as much net service from material wealth as they can. The more wealth they have, other things remaining the same, the better off they are, and the more personal sacrifice they are compelled to undergo in the securing of the wealth, the worse off they are. Some of the benefit received is neutralized by the sacrifice incurred; but there is a net surplus of gains not thus canceled by sacrifices, and the generic motive which may properly be called economic is the desire to make this surplus large. Except in a perfectly isolated individual life, there is opportunity for ethical motives to affect men's economic actions.

Altruism has a place in any _social_ system of economics, and so have the sense of justice and the positive compulsion of the law. Altruism does its largest work in causing men to give away wealth after they have acquired it, but conscience and the law powerfully affect their actions in acquiring it. These are forces of which Social Economics has to take account; but the more egoistic motive, desire to secure the largest net benefit from the wealth-creating process, is one of the premises of any economic science. This involves a general pursuit of wealth; but men seek the wealth for a certain personal effect which comes from the use of it, and they measure it, when attained, by means of this subjective effect.

_How Specific Utilities are Measured._--As the essential quality of wealth is specific effective utility, we measure wealth by estimating the amount of this quality, and it is always a consumer who must make the measurement. He must discover the importance to himself of a small quant.i.ty of a particular commodity. The hunter must find out how much worse off he would be if he were to lose a small part of his supply of game and endure some hunger as a consequence. In doing this he gets the measure of the effective utility of any like quant.i.ty of game, since any one specific part of his supply is as important as any other and no more so. The estimate of the importance of such a supply of food material has to be made in this specific way, by taking the amount on hand piece by piece, and not by gauging the importance of the whole of it at once.

_Value the Measure of Specific Effective Utility._--If any consumer will estimate the importance to himself of a single unit of goods of a certain kind, and multiply the measure so gained by the number of units he is appraising, he will make a measurement of the value of the total amount.

_Values not based on the Importance of the Total Supply of Goods._--It is essential that the consumer, in determining the value of a kind of goods, should not estimate the importance of the supply in its entirety, since that would give an exaggerated measure. Measurements of value are always made specifically, and single units of the supply of goods are appraised apart from the remainder. The total utility of atmospheric air is infinite, since the loss of the whole of it would mean the total destruction of animal life; but the specific utility and the value of air is _nil_, since no one limited part of the supply has any practical importance. A roomful of it might be destroyed with impunity. So the cereal crops of the world, taken as a whole, have almost infinite importance, since their destruction would result in universal famine; but each bushel of grain has an importance that is relatively small. The loss of it would impose no serious hardship upon the average consumer, since he could easily replace it. The value of the crop is determined by the importance of one bushel taken separately and by the number of the bushels. If we estimate the importance of one unit of the supply of anything, express the result of the estimate in a number, and then multiply this by the number of units in the supply, we express the _value_ of this total amount. The _total utility_ of it, on the other hand, is measured by the benefit which we get from the supply in its entirety, or by the difference between the state we are in when we have it all and that to which we should be reduced if we lost it all and were unable to replace it. To measure any such total utility we contrast, in imagination, our condition with the full supply on hand and a condition of total and hopeless privation, in so far as these goods and similar ones are concerned.

_This Method of measuring Wealth Universal._--These principles apply as well to the economy of a solitary islander of the Crusoe type as they do to that of a civilized society. A Crusoe does not need to measure values for purposes of exchange, but he has other reasons for measuring them. It is for his interest to use his own labor economically, and to that end he should not put too much of it into one occupation and too little into another. When, by reason of a large store of wheat on hand, the specific importance of it is small,--or, if we use a common expression, when the utility of the "final increment" of it, which a man might secure by making an addition to his supply, is small,--he should divert his labor to raising goats or building huts, where the utility of the increment of product to be gained is, for the time, greater. The solitary man thus well ill.u.s.trates the act of the society which, in its own peculiar way, sends labor from one department of industry where the "final utility"

of its product is small to another where it is larger. It is all done by measuring the specific importance of goods.[1]

[1] For extended discussions of the relations of utility and value the reader is referred to the works of Jevons, Menger, Von Wieser, Von Bohm-Bawerk, and Walras. A study of "effective" utility and its relations to value, by the writer of the present treatise, is contained in the _New Englander_ for July, 1881.

_The Utility of Producers' Goods._--Consumers' goods have a direct utility, which is a power immediately to serve a consumer. Instruments of production, on the other hand, have indirect utility, since all that they are good for is to help produce things that render the immediate service. They have _productivity_, and this has to be measured in determining their value. What we need to know about hoes and shovels, hammers and anvils, spindles and looms, etc., is how much power they have to create the goods that we want for consumption. Here again the measurement has to be made in the specific way. The capital goods have to be taken unit by unit if their value for productive purposes is to be rightly gauged. A part of a supply of potatoes is traceable to the hoes that dig them; but in valuing the hoes we do not try to find out how much worse off we should be if we had no hoes at all. We endeavor simply to ascertain how badly the loss of one hoe would affect us or how much good the restoration of it would do us.

This truth, like the foregoing ones, has a universal application in economics; for primitive men as well as civilized ones must estimate the specific productivity of the tools that they use, and make hoes, shovels, or axes according as the procuring of a single tool of one kind becomes more important than procuring one of another kind.

Indeed, the measuring of the utility has to be done, as we shall soon see, in a way that is even more specific than this; for the man has to determine not only how many hoes he will make, but how good he shall make them. The quality of each tool has to be determined in a manner that we must hereafter examine with care. The earning power of capital is, as we shall later see, governed by a specific power of productivity which resides in capital goods.

_Cost and Utility._--A ripe consumers' good, in exhausting itself on man, benefits him; but during the period in which it is being prepared for use, when it is receiving utilities at the hands of successive producers, it has an opposite relation to the men who handle it. In making the material useful a man confines and tires himself. He is willing to do it if the reward that he expects will more than pay for the sacrifice, but not otherwise. Moreover, this sacrifice itself has to be estimated specifically in a way that is akin to the method of measuring utilities which determines the values of goods. It is necessary for a man to gauge the sacrifice which is entailed on him, not by his labor as a whole, but by a specific part of it. He finds himself in the evening feeling the fatigue and the sense of confinement which the day of labor has imposed and asks himself how much it would burden him to work a little longer. If what he can get by this means pays for the extra sacrifice involved in thus getting it, he will work for the few minutes, but otherwise he will not. His objection to a few minutes of additional work measures what we may call the specific disutility of labor; and men, whether they be primitive or civilized, are forever making such measurements. They consider how much it will cost them to add slightly to the length of their working day or how much it will benefit them to shorten it. In this way they measure the _specific disutility_ of labor rather than the _total disutility_ of it, since they do not gauge the relief that it would afford to cease working altogether.

_The Increasing Cost of Successive Periods of Labor._--It is easy to work when one is not tired, and the first hour or two of labor may even afford a pleasure that largely offsets the burden that it entails; but it is hard to work when one is tired and painfully conscious of the confinement of the shop. Adding anything to the length of a working day imposes on a man the necessity of working at the time when the burden is greatest; and shortening his day, for a like reason, relieves him of some of his most costly toil.

_The Natural Length of the Working Day._--Any laborer, as his work goes on, hour after hour, is certain to reach a point at which it is unprofitable to go farther. However greatly he may need more goods, he will not need them as much as he needs rest and change. It may be that he has worked twelve hours, and that, by working longer, he can improve his wardrobe, his food, or his furnishings; but if he has a tolerable supply of such things, he will hardly choose to add to it by staying in the shop when his strength has been exhausted and he is eager to reach his home.

_Specific Cost at its Maximum a Measure of Specific Utility._--Two very important principles are at work whenever a man is performing labor in order to create wealth. The more consumers' wealth he gets, the less important to him are the successive units of it, and the more do these successive units cost him. The tenth hour of labor adds to his supply of food, but this addition is not as important as the supplies that were already on hand. If we divide the supply into tenths and let the man produce a tenth in each successive hour, the first tenth, which rescues him from starvation, is the most important, while the last tenth, which comes nearest to glutting his appet.i.te, is least important. This last increment, however, is produced by the greatest sacrifice, for it is gained by making the working day ten hours long instead of nine.

[Ill.u.s.tration]

Let the hours of the working day be counted along the line _AD_, and let us suppose that a man gets unit after unit of consumers' wealth, as he works hour after hour, and the units grow less and less important. The first and most important we may measure by the vertical line _AB_. The second is worth less, the third still less, and the last one is worth only the amount _CD_. This means that the successive units of what we may call general commodity for personal use have declined in utility along the curve _BC_. On the other hand, as the man's labor has been prolonged, it has grown more and more wearying and irksome. The sacrifice that it involved at first was almost nothing, but the sacrifice of the succeeding hours has increased until, in the last hour, it amounts to the quant.i.ty expressed by _CD_.[2] As the man has continued to work, the onerousness of working has increased along the ascending line _AC_ until the point has been reached where it is so great that it is barely compensated by the fruits of the labor. The man will then work no longer. If he were to do so, his sacrifice would become still larger and his reward still less. Up to this point it is profitable to work, for every hour of labor has brought him something so useful that it has more than paid for whatever sacrifice he has made in order to get it. Beyond this point this is not the case. The line _CD_ represents the cost of labor at its maximum, and it is this which acts as a measure of effective utility and value.

[2] If we should try to describe all the possibilities in the case, we should take account of the fact that a man may get a positive pleasure from his first hour or two of labor and construct a figure thus to express this fact:--

[Ill.u.s.tration]

_AC_ is the curve representing the sacrifice entailed by successive hours of labor.

[Ill.u.s.tration]

In like manner we should have to recognize the fact that the utility of some kinds of goods may not reach a maximum with the first increment, and should construct a utility curve to express this fact. _BC_ here represents the increase and the following decrease in the specific utility of the supply of an article of this kind.

_The Coincident Measure of Cost and Utility._--It now appears that the line _CD_ signifies two different things. It measures the utility of the last unit of the man's consumers' wealth, and it also measures the sacrifice that he has incurred in order to get it. These are opposing influences, but are equally strong. The one, of itself, makes man better off, while the other, of itself alone, makes him worse off. At the last instant of the working day they neutralize each other, though in all the earlier periods the utility secured is greater than the sacrifice incurred and the net gain thus secured has kept the man working.

_The Point at which Utility and Disutility are mutually Neutralizing._--At a certain test point, then, production acts on man in such a way as exactly to offset the effect experienced from the consuming of the product. Man, as a consumer, has to measure a beneficial effect on himself, and, as a producer, he has to measure an unpleasant effect. He finds how much he is benefited by the last unit of wealth which he gets for personal use, and also how much he is burdened by the last bit of labor that he performs. If this sacrifice just offsets the benefit derived from the final consumption, it is the best unit for measuring all kinds of utilities. A man secures by means of this final and most costly labor a variety of things, for if he works up to this point every day in the year, he will have at his disposal, say, a hundred hours of labor in excess of what he would have had if he had worked a third of an hour less each day. The product of this extra labor will be taken in the shape of goods that are also extra, or additional to whatever he would otherwise have secured. They will represent special comforts and luxuries of many kinds. The values of these goods may be measured and compared by means of the quant.i.ty of labor that the man has thought it worth while to perform in order to get them. If he values one of them highly enough to think it worth while to work for an extra period of twenty minutes at the end of a day in order to get it, it may be said to have one unit of value; and if he is anxious enough to get something else by doing this on two successive days, this second article may be said to have two units of value. The savage who, by working for an extra hour, makes some improvement in his canoe, and by doing the same thing on another day makes some improvement in his food, establishes thereby the fact that he values these two additional bits of consumers' wealth equally. If he uses ten hours of the same costly kind of labor in making an addition to his hut, he proves that he values that gain ten times as highly as he does either of the others. Establishing values by means of such final costs is a process that goes on in every stage of social evolution.

_Unlike Results of Creating Wealth and Using it Summarized._--Wealth, then, affects a man as a consumer in one way and the same man as a producer in an opposite way. In the one case the effects are favorable, and in the other they are unfavorable. At a certain test point the two effects may be equally strong as motives to action, and so may be said to be equivalent. The man is impelled to work by his desire for a final unit of wealth, and he is deterred from it by his aversion for the final unit of labor which he will have to incur if he secures the benefit. If he performs the labor and gets the benefit, he neither gains nor loses as the net result of this particular part of his labor, though from all other parts of his labor he gets a net surplus of benefit. It is natural to measure all such economic gains in terms of sacrifices incurred at the test point where these are greatest. This is the labor one would have to incur in order to add the means of gratification to his previous supply of consumers' goods.

_Minimum Gains offset Maximum Pains._--Running through and through the economic process are these two different measuring operations. Man is forever estimating the amount of harm that wealth does him when he is in the act of producing it, and the amount of good it does him when he consumes it; and there is always to be found a point where the two amounts are equal. It is the point at which gains are smallest and sacrifices greatest. It is at this point that men measure values in primitive life and in civilized life. How in the intricate life of a modern society the measuring is done we shall in due time see; for the present it is enough that we perceive the universality of the law according to which value is best measured by the disutility of the labor which is most costly to the worker. Organized societies do something which is tantamount to this. It is as though the whole social organism were an individual counting the sacrifices of his most costly labor and getting therefrom a unit for comparing the effective utilities of different goods.

_How Primitive Man tests Value._--It is a mistake to suppose that what is essential in value depends on the existence of an actual market in which things are exchanged for each other. In a market, it is true, values are established and their amounts are expressed in ways that cannot be adopted in primitive life. When we buy a thing, we help to fix the value of it and of other things which are like it. The mere ratios in which things exchange for each other in a market are, however, by no means the essence of value itself. That is something deeper and is one of the universal phenomena of wealth. Value, as we have said, is the measure of the effective utility of things, a kind of measure that every one is frequently compelled to employ, whether he is making goods for himself or buying them from others. A producer who has the option of making different things for himself needs to know what variety of goods can be increased in supply with the greatest advantage to himself as a consumer. Adding to the supply of any one of them is getting a "final" or "marginal" unit of consumers'

wealth. It is something that is needed less than the things that were already on hand. Without making such a comparison of the importance of marginal units of different commodities he cannot use his resources in the way that will do him the most good.[3]

[3] [Ill.u.s.tration]

The terms _marginal_ and _final_ mean essentially the same thing, but the modes of conceiving it differ. When utilities are thought of as supplied one after another, the last is the least important. We may represent a man's enlarging gratifications, not by such a mere series of quant.i.tative increments, but by an enlarging area. We may draw a series of concentric circles, beginning with the smallest, and let this central area inclose the most necessary forms of consumers'

wealth. When we draw a second and larger circle, we inclose between it and the first one a zone which includes those forms which come next in importance. By continuing to draw circles we reach an outermost one which bounds a zone in which are included the least important of the consumer's acquisitions. These are the things which he gets with his costliest increment of labor, and the things which lie beyond the circle last drawn would not pay for the sacrifice which acquiring them would cost. In the accompanying figure the fifth zone includes these "marginal" forms of wealth.

_How Isolated Men measure Final Utility._--If a cave dweller possesses a store of one hundred measures of nuts, he measures the final utility and the value of this store in the manner which we have described. If he were to be deprived of the whole stock, he might starve, but this fact does not afford the basis of the value which he puts on the nuts.

He measures the importance of this consumers' wealth specifically. He tests the effect of losing one measure and no more, and finds that he could lose the single measure without suffering greatly. The difference between having an appet.i.te fully satiated and having it very nearly so is not serious.

[Ill.u.s.tration]

Let _AD_ represent the savage's total supply of food. _AB_ will represent the utility of the first unit; _CD_ of the hundredth. If we supply the food unit by unit, the utility of the successive increments will decline along the curve _BC_. When the man has a hundred units of food, no one unit of it is worth any more than the last one, since if any one were taken away, the last one could be put in the place of it.

The _total absolute utility_ of the food is measured by the area _ABCD_, but the total _value_ will be represented by the rectangle _ADCE_. The area _EBC_ measures the surplus of utility contained in the earlier units in the series.

_The Motive for measuring Values in Primitive Life._--Even the cave dweller would have to measure values, and would thus have to apply the principle of final utility, because he would need to spend his limited productive energies in the way that would do him the most good. When he is nearly satiated with food, he needs other things more than he does food stuffs. If he has secured so much of one product that any additional amount that he may get by an hour's labor would be of less use to him than what he could get of some other product by the same amount of labor, it is important for him to change his occupation and produce that thing of which an additional unit--which will perhaps be the final unit of this more desirable article--has the higher degree of usefulness.

_Final Utility and Labor Cost._--On the supposition that a small store of roots and nuts were incapable of being replaced by any amount of effort and that no other food were to be had, the utility of it would be indefinitely great, since the man's life would depend on this one increment of food alone. A man would value that life-sustaining good for what it would do for him and without any reference to the amount of work he had performed in order to get it, or to the amount he would have to perform in order to get another store like it. On the supposition that by labor the man could replace this essential supply, the effective utility of it would be gauged by the sacrifice he would have to make in order to replace it. The effective utility of any unit of a good that an hour's labor will produce can never be more than enough to offset the disutility of a marginal or final hour of labor; and thus even a single unit of replaceable food stuff, even when it stands alone and const.i.tutes the whole supply, is valued according to the cost of getting another one like it. A man will prize it according to his dread of the sacrifice involved in getting the duplicate. If he gets this by adding an hour of labor to his day's work, this fact is an evidence that the importance of the original supply of the food is measured and expressed by this personal cost of replacement; and as any similar quant.i.ty in a large supply of food can be duplicated by the same amount of labor, it appears that, by a standard based on cost, the _effective_ utilities of all units are equal, that of each one is measured by the "disutility" of an hour's labor and that of the whole supply is this amount multiplied by the number of units that this supply contains.[4]

[4] [Ill.u.s.tration]

Although we may use the terms _final utility_ and _effective utility_ in a way that makes them nearly interchangeable, it is clear that the qualities for which the two terms stand are by no means identical, and that effective utility must be studied in any complete a.n.a.lysis of value. In distinguishing final utility we a.s.sume that the units of the supply of goods of a particular kind are furnished one by one, and we measure the absolute utility of each unit. The line _AB_ measures the _absolute_ utility of the first unit supplied. This measurement does not take any account of the cost of replacing this unit, for it does not recognize the possibility of replacing it. What is estimated is the absolute importance of the service which this first unit of the article renders, on the supposition that, if this first increment of the supply were wanting, the service would not be rendered at all. It is, in like manner, the absolute utility of the successive increments supplied which declines along the curve _BC_. _DC_ measures the _absolute_ utility of the final increment, and the area _ABCD_ the total absolute utility of the supply. If the goods can be reproduced by labor, the total effective utility is less, since it is measured, as we have seen, by the amount of sacrifice which the replacing of one lost unit would entail multiplied by the number of units in the supply. It is the amount expressed by the area _AECD_ which is the amount of the value of the goods, since measure of effective utility and value are the same, both in the case of a single unit and in that of a total supply.

We have discovered two reasons why the effective utility of any one of the earlier units is equal to the absolute utility of the final one. The first reason is that, if any one of them were lost, the final one would be put in the place of it and the consumer would suffer no loss except what would be entailed by going without the last unit. The second reason is that if the consumer should lose any one of the earlier units, he could replace it by the same amount of labor that would replace the final one. We have seen that the line _DC_ of the figure expresses not only the absolute utility of the final unit of goods, but the disutility of the labor of reproducing it or of reproducing any other unit. The cost of replacing the whole supply is expressed by the area _AECD_, on the supposition that the units are replaced, one at a time, by means of labor performed at the end of several working days when the sacrifice is greatest. Total value is thus quant.i.tatively equivalent to total _effective sacrifice of replacement_, as well as to total effective utility. If, by adding a brief period to the length of one working day, a man can make good the loss of one unit of the goods, by adding the same period to the length of a number of working days, he can make good the loss of the total supply. For simplicity we a.s.sume that the man's physical condition remains unchanged, and that an extra hour of labor at the end of any one day costs him as much as it would at the end of any other.
