But all the efforts of men in the most developed economy cannot make to disappear the differences in the quality of goods and agents. Desirable goods to consume are limited in quantity, and they vary in quality; hence they have value and some higher than others. Likewise, durable material agents and sources of power are limited in number and vary in convenience of location and efficiency. As men seek to gratify their desires, they attach importance to these agents of power. Each is valued for its service or its series of services. When anything is seen to contain a series of uses, it becomes a rent-bearer, and the economic problem of rent arises, one step more complex than the problem of valuing simple consumption goods.
CHAPTER 8
THE RENTING CONTRACT
§ I. NATURE AND DEFINITION OF RENT
Temporary use and permanent possession of agents
1. The temporary use of materials and power and their sources is necessary to bring most enjoyable goods into being. Indirect goods have value solely because they help to get direct goods. The apple-tree is valued because it bears fruit, and the orchard because the trees give promise of yielding a succession of crops for years to come. There are thus two problems of value in connection with durable goods: that of the value of a temporary use for a brief period, as for a year; and that of the value of a thing itself, the use-bearer, for a long series of years or in perpetuity. To explain what fixes the value of the temporary use is the problem of rent; to explain what determines the value of long-continued use or of permanent control and ownership of a use-bearer is the problem of capitalization.
Origin of the term rent
2. The term rent is used in a number of senses, which must be carefully distinguished. The original meaning of rent was any regular income or revenue arising from wealth. The word comes from the low Latin renta from renda, in turn from redditus, that which is given, yielded or given back, or rendita, that which is given or returned. The French rendre (English render), to give or return that which belongs to one, is used very early. Chaucer used "rente" as an income. "Cattle had he enough and rente," cattle probably meaning property (chattels), and rente income. Rental is a collective term for a number of rents. The total yield of an estate was called its rental or rent-roll, and a list of the various sources of income, including all payments from tenants in money, produce or services, constituted its rental.
