If market participants notice that a variable behaves differently now than in the past, then, according to rational expectations theory, we can expect market participants to A) change the way they form expectations about future values of the variable. In this paper, we develop a model of expectation formation where agents form their forecasts of inflation by selecting a predictor function from a set of costly alternatives whereby they may rationally choose a method other than the most accurate. It is important to note that expectations and outcome influence each other. B) conventional econometric models as indicators of the potential impacts on the economy of particular policies.
