Pareto is sometimes credited with an early formulation of the ill-fated Hicks or Kaldor principles of hypothetical compensation. The basis for this claim is Pareto's 1894 article "Il massimo di utilitÁ dato dalla libera concorrenza." However in that paper Pareto argued to the contrary, that in...

In the present note we construct an overlapping-generations (OLG) example in which free trade is Pareto-improving and the world equilibrium chaotic. The example is simple, but it is not incompatible with the general model of Kemp and Wolik.

The conclusions of the 1976 Kemp-Wan proposition are shown to be substantially valid even if all tariff vectors, both pre-union and post-union, are optimally chosen.

The Torrens-Ricardo Principle of Comparative Advantage rests on the special assumptions that, both in autarky and under free trade, all countries can produce all commodities and that, in autarkic equilibrium, each country consumes all producible commodities, at least incipiently. We reformulate...

It is well known that if the autarkic and free-trade equilibria are perfectly competitive with market distortions limited to non-negative taxes on imports and exports then free trade is potentially (after country-specific lumpsum compensatory transfers) beneficial for each trading country. It...
