Fully rational agents are allowed to optimize over expectations formation technologies in an environment where it is costly to collect and process information. It is shown in a general equilibrium framework that optimization over expectations by rational and forward oriented agents can lead to endogenous instability. Specifically, we illustrate that resulting equilibria can be both chaotic and ...

This paper establishes existence of a stationary Markov perfect equilibrium in general stochastic games with noise — a component of the state that is nonatomically distributed and not directly affected by the previous period’s state and actions. Noise may be simply a payoff-irrelevant public randomization device, delivering known results on existence of correlated equilibrium as a special case....

This paper develops a dynamic general equilibrium matching model with many types of long-lived workers, many types of jobs and stochastic transitions between many possible aggregate productivity states. The supply of new jobs is determined by free entry, matching is directed, wages are determined by auction and workers can continue to search on-the-job for better employment opportunities. We sh...

Theories based on partial equilibrium reasoning alone cannot explain the widespread negative cross-sectional correlation between parental wages and fertility, without restrictive assumptions on preferences and childcare costs. We argue that incorporating a dynamic general equilibrium analysis of returns to human capital can help explain observed empirical patterns. Other by-products of this the...

We present an application of the theory of stochastic processes to model and categorize non-equilibrium physical phenomena. The concepts of uniformly continuous probability measures and modular evolution lead to a systematic hierarchical structure for (physical) correlation functions and non-equilibrium thermodynamical potentials. It is proposed that macroscopic evolution equations (such as dyn...

We estimate the dynamic stochastic general equilibrium model of Christiano, Eichenbaum, and Evans (2005) on United Kingdom data. Our estimates suggest that price stickiness is a more important source of nominal rigidity in the U.K. than wage stickiness. Our estimates of parameters governing investment behavior are only well behaved when post-1979 observations are included, which reflects govern...
