We introduce the E-correspondence principle for stochastic dynamic expectations models as a tool for comparative dynamics analysis. The principle is applicable to equilibria that are stable under least squares and closely related learning rules. With this technique it is possible to study,...

This paper shows that price rigidity evolves in an economy populated by imperfectly rational agents who experiment with alternative rules of thumb. In the model, firms must set their prices in face of aggregate demand shocks. Their payoff depends on the level of aggregate demand, as well as on...

In this paper we test the Rational Expectations hypothesis using longitudinal data on expectations and realizations of individual welfare for East Germans in the years following reunification. German reunification was unexpected and delivered a large shock to the future prospects of the...
