SEC: The abbreviation for Securities and Exchange Commission, which is a federal government agency that regulates the trading of corporate stock to protect investors against unscrupulous practices. Like a number of other federal regulatory agencies, the SEC was established in the 1930s--1934 to be exact. The impetus for its formation was to prevent investors from manipulating the stock market and to prevent other practices that contributed to the 1929 stock market crash. The SEC has all sorts of rules governing the stock market, including information disclosure, insider trading, speculation, and use of credit.

BARRIERS TO ENTRY

Institutional, government, technological, or economic restrictions on the entry of participants into a market or industry. The four primary barriers to entry are: (1) resource ownership, (2) patents and copyrights, (3) government restrictions, and (2) start-up cost. Barriers to entry are a key reason for market control and the inefficiency that results. In particular, monopoly, oligopoly, monopsony, and oligopsony often owe their market control to assorted barriers to entry. By way of contrast, perfect competition, monopolistic competition, and monopsonistic competition have few if any barriers to entry and thus little or no market control.
