The Efficiency Market Hypothesis Finance Essay
The brief debate between Keynesians and new classical economists in the 1980s was fought primarily over (a) and over the first three tenets of Keynesianism—tenets the monetarists had accepted. New classicals believed that anticipated changes in the money supply do not affect real output; that markets, even the labor market, adjust quickly to eliminate shortages and surpluses; and that may be efficient. For reasons that will be made clear below, I believe that the “objective” scientific evidence on these matters points strongly in the Keynesian direction. In the 1990s, the new classical schools also came to accept the view that prices are sticky and that, therefore, the labor market does not adjust as quickly as they previously thought (see ).
Finally, there was the European depression of the 1980s, the worst since the depression of the 1930s. The Keynesian explanation is straightforward. Governments, led by the British and German central banks, decided to fight inflation with highly restrictive monetary and fiscal policies. The anti-inflation crusade was strengthened by the European monetary system, which, in effect, spread the stern German monetary policy all over Europe. The new classical school has no comparable explanation. New classicals, and conservative economists in general, argue that European governments interfere more heavily in labor markets (with high unemployment benefits, for example, and restrictions on firing workers). But most of these interferences were in place in the early 1970s, when unemployment was extremely low.
Efficient Market Hypothesis Essay Examples
Investors buy stocks they expect to have a higher-than-average return and sell those they expect to have lower returns. When they do so, they bid up the prices of stocks expected to have higher-than-average returns and drive down the prices of those expected to have lower-than-average returns. The prices of the stocks adjust until the expected returns, adjusted for risk, are equal for all stocks. Equalization of expected returns means that investors’ forecasts become built into or reflected in the prices of stocks. More precisely, it means that stock prices change so that after an adjustment to reflect dividends, the time value of money, and differential risk, they equal the market’s best forecast of the future price. Therefore, the only factors that can change stock prices are random factors that could not be known in advance. Thus, changes in stock prices follow a random walk.
Efficient market hypothesis (EMH), first promulgated by Eugene F
Although Friedman did not formally apply the concept of rational expectations in his work, it is implicit in much of his discussion. Because of its heavy emphasis on the role of expectations about future income, his hypothesis was a prime candidate for the application of rational expectations. In work subsequent to Friedman’s, John F. Muth and Stanford’s Robert E. Hall imposed rational expectations on versions of Friedman’s model, with interesting results. In Hall’s version, imposing rational expectations produces the result that consumption is a random walk: the best prediction of future consumption is the present level of consumption. This result encapsulates the consumption-smoothing aspect of the permanent income model and reflects people’s efforts to estimate their wealth and to allocate it over time. If consumption in each period is held at a level that is expected to leave wealth unchanged, it follows that wealth and consumption will each equal their values in the previous period plus an unforecastable or unforeseeable random shock—really a forecast error.
