Rational Expectations Theory

In economics, a theory stating that economic actors make decisions based on their expectations for the future, which are based on their observations and past experiences. A basic example of rational expectations theory is a situation in which a consumer delays buying a certain good because, based on his/her observations and experiences, he/she believes that the price will be less expensive in a month. If enough consumers believe that, demand eases and the good is likely to actually be less expensive next month. Thus, the consumer waits a month before buying the good. Rational expectations theory states that current expectations strongly influence future performance. Economists disagree about how well the rational expectations theory works in the real world.
