4. _The manipulation of dividends and the resulting changes in capitalization open up great opportunities for the dishonest increase of private fortunes._ A great change in the market value of stock is made by a comparatively small change in the income it regularly affords, for if the prevailing rate of interest on money loans is five per cent., each dollar of dividends is capitalized at $20. It might seem that the dividend would be declared if earned, otherwise not. The matter is not so simple and impersonal, however. The control of corporations is vested in the hands of a small group of directors who have both the opportunity and the temptation to withhold dividends when they are earned, to pay them with borrowed money if unearned, and in either case to keep the stockholders and the public in ignorance of the real condition and earning power of the business. The stocks can, by this manipulation of dividends, be made a lottery for the legitimate investor, a trap for the unwary, and a source of unrighteous gain by men recreant to their trusts. In this way it may be seen that an earning power not known to bidders in the market does not enter into capitalization; a fictitious earning power, however, is capitalized so long as the investors continue to be deceived. Instances of this kind present problems not only of private morality, but of the preservation of free industrial institutions. The solution of these problems would perhaps be hastened if the a economic nature of capitalization were more clearly understood. Capital value in modern industry is everywhere the expression of the serial rents of wealth, discounted at a prevailing rate of time discount. CHAPTER 16 INTEREST ON MONEY LOANS § I. VARIOUS FORMS OF CONTRACT INTEREST [Sidenote: Distinction between contract interest and time-value] 1. _Interest, the amount paid according to contract by one person to another for credit given in terms of money, is but one expression of a larger problem, that of the difference in present worth of goods at two periods of time._ This larger problem appears under several forms: first, as a difference in value, due to time, where there is no money expression (to be considered in the following chapter); second, in discount on a money loan for a short, definite time; third, in a long-time money loan at a fixed rate of interest; fourth, in a credit loan--that is, the sale of the thing on credit in terms of money.
