To be useful as a guide to behavior, a model that includes a relationship between x_t and z_t+1 must specify whether x_t is influenced by the expectation at t of z_t+1 or, that z_t+1 is inertially influenced by x_t. We show that, for a broad class of linear RE models, distinct causal...

It is well known that the concept of "determinacy"-a single stable solution-plays a major role in contemporary monetary policy analysis. But while determinacy is desirable, other things equal, it is not necessary for a solution to be plausible and is not sufficient for a solution to be...

The 'new open-economy macroeconomics' seeks to provide an improved basis for monetary and exchange-rate policy through the construction of open-economy models that feature rational expectations, optimizing agents, and slowly adjusting prices of goods. This paper promotes an alternative approach...

We consider what, if any, relationship there is between monetary aggregates and inflation, and whether there is any substantial reason for modifying the current mainstream mode of policy analysis, which frequently does not consider monetary aggregates at all. We begin by considering the body of...
