With the beginning of the corporate form of organization there also began a desire on the part of persons to buy and sell stocks and bonds. Soon a need was felt for some sort of central market where buyers and sellers, or their agents, could meet to bargain. The result was the stock exchange, such as the one in New York City, where the members come together daily for the purpose of buying and selling stocks and bonds, usually for their customers. The development of such a central market has affected favorably the growth and spread of corporations. Investors are easily persuaded to buy stocks and bonds, since they know that they can dispose of them without difficulty. In other words, investments in stocks and bonds are liquid investments. Consequently, billions of dollars have been saved to industry, which otherwise would have been consumed or invested to less advantage.
