This paper distinguishes two kinds of Endogenous Business Cycle models; EBC1 models, which display dynamic indeterminacy, and EBC2 models, which display steady-state indeterminacy. Both strands of the literature have their origins in the sunspot literature that developed at the University of...

This paper constructs a simple model in which asset price fluctuations are caused by sunspots. Most existing sunspot models use local linear approximations: instead, I construct global sunspot equilibria. My agents are expected utility maximizers with logarithmic utility functions, there are no...

In recent years economists have begun to use the techniques of non-linear dynamics to show that some apparently erratic and turbulent economic phenomena reflect subtle underlying patterns. How do cyclic and chaotic dynamics arise in economic models of equilibrium? How can empirical methods be...

We show that sentiments - self-fulfilling changes in beliefs that are orthogonal to fundamentals - can drive persistent aggregate fluctuations under rational expectations in a beauty contest game. Such fluctuations can occur even in the absence of exogenous aggregate fundamental shocks....

We introduce a simple adverse selection problem arising in credit markets into a standard textbook real business cycle model. There is a continuum of households and a continuum of anonymous producers who produce the final goods from intermediate goods. These producers do not have the resources...
