Encyclopedic overview
Rational expectations is a set of modeling assumptions describing how macroeconomic agents form expectations about the future under uncertainty. Under these assumptions, agents are presumed to use all relevant and available information, making their expectations “model‑consistent”—that is, behaving as if they fully understand the structural model governing the macroeconomy.
