In light of research questioning the usefulness of economists' models of exchange-rate determination, this paper investigates the rationality of survey measures of expectations for Deutschmark/dollar exchange rates for 1989-97. Using Liu and Maddala's (1992) "restricted cointegration" test, the...

This paper examines the robustness characteristics of optimal control policies derived under the assumption of rational expectations to alternative models of expectations. We assume that agents have imperfect knowledge about the precise structure of the economy and form expectations using a...

This paper provides a selective review of theoretical research on the consistency of rational expectations equilibrium and its properties in microeconomic models. The general equilibrium framework is emphasized throughout the paper. After defining rational expectations equilibrium for a pure...

Methods are presented for solving a certain class of rational expectations models, principally those that arise from dynamic games. The methods allow for numerical solution using spectral factorization algorithms and for estimation of these models using maximum likelihood techniques.

A large body of literature has failed to find conclusive evidence that the expectations theory of the term structure holds in U.S. data. This paper asks more narrowly whether the theory holds conditional on an exogenous change in monetary policy. We argue that previous work on the expectation...

The notion of asset market efficiency -- that market prices "fully reflect" all available information -- requires the operation of mechanisms that rapidly incorporate new information into asset prices. Particularly problematic -- both theoretically and empirically -- has been the case where new...

Even though pieces of empirical evidence individually may corroborate an economic theory, their joint existence may refute that same theory. We discuss examples concerning testing for omitted variables, simultaneity, and rational expectations in the context of general-to-simple versus...
