Abstract:
This introduces the symposium on sunspots and lotteries. Two stochastic general equilibrium concepts, Sunspot Equilibrium (SE) and Lottery Equilibrium (LE), are compared. It is shown that, for some general, pure-exchange economies which allow for consumption non-convexities or moral hazards, the set of LE allocations is equivalent to the set of SE allocations provided that the randomizing device can generate events of any probability.
