_The stock exchange._--The last mentioned forms of indebtedness so easily become matters of everyday purchase and sale as to lead to the business of stock brokerage, found everywhere in greater or less extent. In large cities the brokers naturally unite for convenience of business in the so-called stock exchange, in which the market price of all current forms of indebtedness or deferred payments is fixed from day to day, or from hour to hour, by the higgling of the market, just as the price of produce is fixed in the produce exchange. Naturally, as in the case of produce, a fictitious business, purely speculative, grows up around the legitimate dealing in stocks and bonds. Other forms of deferred payments enter less into the business of the brokers, because the market value of any particular mortgage or individual note cannot be easily determined outside the immediate neighborhood where it is made. The chief way in which these enter the general brokers' market is through the stock or bonds of large brokers' companies, sometimes called guaranty loan companies. In this way the universal extension of credit through deferred payments finally has its effect upon the general confidence. The broker's business grows legitimately out of the need of ready transfer of claims, for the sake of larger use of the floating capital of the country, and readiness of investment in more fixed forms. It adds, however, to the dangers of extended credit by making more easy the gratification of present wants through expectation of future ability. The broker makes his gain, without reference to the final settlement, by taking a commission upon the loan. His interest leads to an overestimate of the borrower's ability, and cases are not infrequent where appraisers of real estate have been hired by brokers to misrepresent the value of property, for the sake of securing improper loans.
Every period of expanding credit in speculative movements has furnished proofs of this tendency. A standing example is furnished in mining stocks, in which the temptation to misrepresent prospects by "salting" and false assays is proverbial. Almost as notorious are the misrepresentations associated with bonds of newly established cities or other municipalities. Not all such misrepresentation is intended fraud, but the immediate interest of the broker clouds his judgment as to conditions of final settlement. With little to lose and everything to gain in the immediate transaction, his judgment is necessarily biased. The merely speculative buying and selling of stocks by margins has little to do with the general character of indebtedness, except to increase somewhat the risks of legitimate brokerage. The "bulls and bears" on exchange make their gains by fluctuations in market values, and, like all gamblers, delight in producing false impressions upon their opponents in the game. This fact adds to the uncertainty of all standing credit, and so increases the natural rate of interest. This effect upon interest will be noticed in considering the nature of interest and conditions affecting it.
