We impose a horizontal equity restriction on the problem of finding the optimal utilitarian tax mix. The horizontal equity constraint requires that individuals with the same ability have to pay the same amount of taxes regardless of their preferences for leisure. Contrary to normal findings, we...

A dynamic general equilibrium model that generalises Roemer's [23] economy with a global capital market is analysed. An axiomatic analysis of the concept of unequal exchange (UE) between countries is developed at general dynamic equilibria. The class of UE definitions that satisfy three...
