But many other goods are rented
Many less durable goods are rented for brief periods. Carriages are rented for the day, bicycles by the week or month. Sewing-machines, boats, guns, tents, and even diamond engagement rings, yield their joys under the renting contract. People frequently hesitate between the renting and the purchase of a piano, and in some cases renting is the more convenient and desirable way of securing its use. The purchase of a dress-coat or of a masquerade-suit to be worn but once, involves for some an excessive and needless sacrifice. For a moderate sum its temporary use may be had, and it is then returned, little the worse for wear, to the accommodating clothier.
Economic rent much wider than the renting contract
A final word of caution may be given. Economic rent is not confined to the cases of contract rent. It exists in every case where a more or less durable agent yields a use that is scarce and desirable. The owner who uses a thing himself gets the advantage in the product as clearly as if he collected rent from a borrower. Houses lived in by the owners, house furnishings, clothing, books, all scarce and durable agents, are yielding rents in this logical sense. To the economist, therefore, the problem of economic rent, as one of the grand divisions of the problem of value, remains of undiminished importance, for in these unceasing streams of uses emanating from our environment, is found the basis for the value of all durable wealth.
