Ex - ante and ex - post strong correlated

A strong correlated equilibrium is a strategy pro le that is immune to joint deviations. Di erent notions of strong correlated equilibria were de ned in the literature. One major di erence among those de nitions is the stage in which coalitions can plan a joint deviation: before (ex-ante) or after (ex-post) the deviating players receive their part of the correlated pro le. In this paper we prov...

Ex Post and Ex Ante Analysis of Provisional Data

In this paper we suggest a framework to assess the degree of reliability of provisional estimates as forecasts of nal data, and we reexamine the question of the most appropriate way in which available data should be used for ex ante forecasting in the presence of a data revision process. Various desirable properties for provisional data are suggested, as well as procedures for testing them, tak...

But both international trade patterns and international business cycle correlations are endogenous. Theoretically, economic integration has an ambiguous effect on the degree to which business cycles are correlated ...
