In this paper the role of behavioral forecasting rules of chartist and fun-damentalist type for the dynamic macroeconomic stability of a two-country system is investigated both analytically and numerically. The main result of the paper is that for large trend-chasing parameters in the chartist...

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...

The paper presents an intertemporal general equilibrium model with rationing in the product market, in which stationary sunspot equilibria are shown to exist, indicating the possibility of fluctuations in economic activity simply due to self-fulfilling variations in economic agents'...
