Key Concepts

Rational Expectations

Rational expectations is the hypothesis that, on average, economic forecasts are made using all available information and that any deviations from actual outcomes are random rather than systematic errors. This concept implies that while forecasts may be imperfect, they are not systematically biased if economic agents correctly utilize the information at hand.

Forecasting Errors

Forecasting errors refer to the discrepancies between predicted and actual outcomes. In the context of rational expectations, such errors are expected because of inherent uncertainty, unpredictable shocks, or incomplete information, and do not necessarily indicate irrational forecasting behavior as long as the errors are not systematic.

Information Limitations and Uncertainty

This concept highlights that even when all available information is used, the complexity of economic systems and the occurrence of unforeseen events can lead to inaccuracies in forecasts. The presence of these unpredictable factors means that 'inaccuracies' in predictions may arise from the structure of economic models and the nature of uncertainty, rather than from irrational judgment.
