We review how realistic frictions in information and/or rationality arrest general equilibrium (GE) feedbacks. In one specification, we maintain rational expectations but remove common knowledge of aggregate shocks. In another, we replace rational expectations with Level-k Thinking or a smooth...

It is common to analyze the effects of alternative monetary policy commitments under the assumption of fully model-consistent expectations. This implicitly assumes unrealistic cognitive abilities on the part of economic decision makers. The relevant question, however, is not whether the...

This paper analyzes the relationship between forward exchange rates,future spot rates and new information. A stochastic model of exchangerate determination is used to formally show how unanticipated changes in the exchange rate determinants (or "news") affect the spot rate. The empirical...

This paper reviews and contrasts different views about the role of expectations in policy research and practice. Recently, two widely different views seem to have dominated the analysis of policy questions.One view, which is referred to as the "new classical macroeconomic"view, is that...

This paper tests the joint hypothesis of rational expectations and the expectations model of the term structure for three- and six-month Treasury bills. Previous studies are extended in three directions. First, common efficient markets-rational expectations tests are compared, and it is shown...
