Rational expectations theory
Rational expectations theory suggests that individuals and businesses make decisions based on their best understanding of the future, using all available information. Instead of guessing or relying solely on past experiences, people form expectations about economic outcomes—like inflation or interest rates—by considering current data and trends. This means that, on average, their predictions are accurate, and any systematic errors are minimized. Consequently, when policymakers try to influence the economy, these expectations can reduce the effectiveness of their actions because people adjust their behavior in anticipation of these changes.

Rational Expectations Theory posits that individuals and businesses make decisions based on their predictions of the future, using all available information. Instead of acting on past trends or biases, they form expectations that are, on average, accurate. This means that people anticipate the effects of economic policies and changes, which can influence their behavior. For example, if a government announces a tax cut, people may predict how it will impact their spending and saving. As a result, the theory suggests that economic outcomes are often shaped by the collective expectations of individuals rather than just external factors.

Rational expectations theory suggests that individuals form their predictions about the future based on all available information and past experiences. It posits that people are generally forward-looking and use reasoning to make informed decisions, such as in economics or finance. This means that if policies change, people will adjust their behaviors accordingly, as they anticipate future outcomes based on the new information. Consequently, the theory implies that systematic government policies may have limited effects because people will alter their expectations to account for those policies.
