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...

We explore alternative approaches to numerical solutions of large rational expectations models. We discuss and compare several current alternatives, focussing on the tradeoffs in accuracy, space, and speed. The models range from representative agent models with many goods and capital stocks, to...

We examine the role of generalized constant gain stochastic gradient (SGCG) learning in generating large deviations of an endogenous variable from its rational expectations value. We show analytically that these large deviations can occur with a frequency associated with a fat tailed...
