Sunspots, correlation and competition

Abstract

Correlated equilibria in strategic market games played, simultaneously, by ìoverlapping generationsî of players correspond to sunspot equilibria in the associated, competitive economy. The higher the degree of competition, the larger the range of parameters that allow for effective correlation or endogenous stochastic fluctuations.
