There is now a great deal of empirical evidence that business cycle fluctuations contain asymmetries. The asymmetries found in post-war U.S. data are inconsistent with the behavior of the U.S. economy in the Great Depression. In a model where business cycle asymmetries are produced by rational...

In this paper I described group theoretic methods that can be used for analyzing the boundary problems, which arise when the Hamiltonian method is applied to solve the relaxed problem for the multidimensional screening problem. This technique can provide some useful insights into the structure...
