The Principles of Economics, with Applications to Practical Problems. Frank A. Fetter
and you will be happy," "Honesty is the best policy," and "Virtue is its own reward," have a sound basis in the age-long experience of the world. Cynics or jesters may easily disprove these truths in a multitude of particular cases.
Freemen are not economic wealth
6. Wealth does not include such personal qualities as honesty, integrity, good health. Some economists speak of these as "internal goods," but it is far better not to speak of free men or of their qualities as wealth. Many difficulties arise from such a use of the term in practical discussion. One of the most important of all distinctions to maintain in economics is that between material things and men. Only in the case of human slavery may persons be counted as economic wealth. It is a different thing, however, to consider human services as wealth of an ephemeral kind at the moment they are rendered. We are, thus merely recognizing that men may bear at the given moment the same relation to our wants as do material things.
§ II. SOME IMPORTANT ECONOMIC CONCEPTS CONNECTED WITH WEALTH AND WELFARE
Popular meaning of useful
1. Utility, in its broadest usage, is the general capability that things have of ministering to human well being. The term is evidently one without any scientific precision. It expresses only a general or average impression that we have in reference to the relation of a class of goods to human wants. Every one would agree to the statement that "water is useful," thinking of the fact that it is indispensable to life and that it ministers to life in a multitude of ways. But what of water in one's cellar, water soaking one's clothes on a cold day, water breaking through the walls of a mountain reservoir and carrying death and destruction in its path? The poison that is doing what we at the moment desire, we call useful; that doing what we would prevent, we call harmful. Noxious weeds become "useful" by the discovery of some new process by which they can be worked into other forms, though they may still continue to be noxious in many a farmer's fields. The utility of anything, therefore, is seen to be of a relative and limited nature. The term "utility" in popular speech is very inexact. It can be employed in economic discussion only when carefully modified and defined.
Kinds of goods
2. Goods consist of all those things objective to the user which have a beneficial relation to human wants. They fall into several classes. We may first distinguish between free and economic goods. Free goods are things that exist in superfluity, that is, in quantities sufficient not only to gratify, but to satisfy all the wants that may depend on them. Economic goods are things so limited in quantity that all of the wants to which they could minister are not satisfied. The whole thought of economy begins with scarcity; indeed, even the conception of free goods is hardly possible until some limitation of wants is experienced. Practical economics is the study of the best way to employ things to secure the highest amount of gratification. The problem itself arises out of the fact that many things are used up before all wants dependent on them are completely satisfied.
A distinction is often made between consumption and production goods, or it may be better to say immediate and intermediate goods. Consumption goods are those things which are immediately at the point of gratifying man's desires. Production goods are those things which are not yet ready to gratify desires; some of them, being merely means of securing consumption goods, never will themselves immediately gratify desire.
Value is utility given precision
3. Value, in the narrow personal sense, may be defined as the importance attributed to a good by a man. The vagueness and inexactness of the word "utility," or the word "good," disappears when we reach the word "value." It is not a usual relation or a vague degree of benefit sometimes present and sometimes absent, but it refers to a particular thing, person, time, and condition. Value is in the closest relation with wants, and in this narrow sense depends on the individual's estimate. From the meeting and comparison of the estimates of individuals, arise market values or prices, which are the central object of study in economics.
CHAPTER 4
THE NATURE OF DEMAND
§ I. THE COMPARISON OF GOODS IN MAN'S THOUGHT
Wants and goods must be constantly adjusted
1. As wants differ in kind and degree, so goods differ in their power to gratify wants. This general and simple statement unites the leading thoughts of the two chapters preceding. Confirmation of its truth may be found in observation and experience. The purpose of this chapter is to show how, starting from the general nature of wants and the nature of goods, we can arrive at an explanation of the exchange of goods. Recognizing the simple but fundamental fact stated at the opening of this paragraph, an exchange may be seen to be a rational and a logical result when men are living together in society.
Ripe and unripe goods
2. Immediately enjoyable goods are the first objective things whose value is to be explained. Goods come into relation with wants in a multitude of ways. Some things will not gratify a want until after the lapse of a long time, as ice cut in December and stored for summer use. Other things will never themselves directly gratify a want, but will be of help in getting things that do; such are the young fruit trees planted in the orchard, and the hammer that will be used to drive nails in a house that will shelter men. Still other things are gratifying wants at this moment, or are ready for use and will be used up in a very short time; examples of such are the food on the table and in the pantry, and the cigar in the pocket. All these things are called goods, because of their beneficial relation to man's desires, but the relation is very immediate in some cases, very remote in others. The value of all goods is to be explained, but the explanation will be more or less complex according to the directness or indirectness of their relation with wants. As it is the power of goods to gratify wants that alone causes value to be attributed to them, those goods which are ripest, which are ready to gratify wants, are nearest to the source of an explanation. The value of unripe enjoyments must be traced to some expected gratification as its cause or basis. In order to attack the difficulties one by one we will, therefore, in the following discussion, deal first with this class of ripe, consumable goods, as food, personal services, enjoyments of any sort that are immediately available. The explanation of these cases of value must precede that of cases in which the relation to wants is less obvious and direct.
The law of diminishing utility
3. As the amount of any good increases, after a certain point the gratification that the added portions afford decreases. This is called the law of the diminishing utility of goods or of the decreasing gratification afforded by goods. The reason for the truth of this proposition is found in the very nature of man and his nervous organization. Any stimulus to the nerves, however pleasant at first, becomes painful when long continued or increased unduly. The trumpet too distant at first for the ear to distinguish its notes, may swell to pleasing tones as it approaches, until at length its volume and its din may become absolutely painful. If we were to express the degree of gratification by a curve, we should see the curve rising gradually to a maximum, and then falling somewhat suddenly and becoming a negative quantity, when pain, not pleasure, resulted. The same change could be illustrated by any sensation or by any of men's activities.
The proposition must be understood as applying to the gratification resulting from each added portion of the sensation. There is a maximum point in the gratification afforded by any nerve-stimulus. A man coming in from the winter's storm and holding out his hands before the fire, feels an intense pleasure in the grateful warmth; a few moments later, the same heat becomes unpleasant. In winter we wish for a moderation of the temperature; on the sultry days of summer, we think of a cool breeze as the most to be desired of all things. Whether the temperature rises or falls, there is a point beyond which the change is no longer an addition to,
