Thomas A. Rietz (1988) proposes that the possibility of rare disasters (such as economic depressions or wars) is a major determinant of asset risk premia. Robert J. Barro (2006) shows that, internationally, disasters have been sufficiently frequent and large enough to make the Rietz proposal viable, and they account for a high equity premium. The Rietz-Barro hypothesis is almost always formulat...

We analyze the effect of price caps on equilibrium production and welfare in oligopoly under demand uncertainty. We find that high price caps always increase production and welfare as compared to the situation without price cap. Price caps close to marginal cost may lead to zero production, depending on the nature of uncertainty. We characterize the optimal price cap and show that typically, th...

This work studies the price of anarchy and the price of stability of cost-sharing methods in weighted congestion games. We require that our cost-sharing method and our set of cost functions satisfy certain natural conditions and we present general tight price of anarchy bounds, which are robust and apply to general equilibrium concepts. We then turn to the price of stability and prove an upper ...
