This paper proposes a new decomposition of welfare effects simulated by Computable General Equilibrium (CGE) models. Rather than relying on first order approximations, our approach is based on Taylor series approximations of CGE specifications and thus is path independent. This decomposition is...

This paper formulates a specific factor model of trade with skilled and unskilled workers as the specific and capital as the mobile factors. Production of goods is subject to intermediation and corruption. We then allow for international capital mobility and show that corruption as an activity...

In an equilibrium trade model, we prove that not only the diversity effect but also the kurtosis effect will affect the pattern of comparative advantage. Furthermore, we find that, against the conventional results, if the kurtosis effect dominates the diversity effect then a country with more...

We consider an exchange economy with an atomless space of consumers whose preference relations need not be monotone. We prove that if for every commodity, there is a group of consumers who regard it as potentially desirable, in a sense to be made precise, then there exists a competitive...

The article analyzes the Dynkin (1975) stochastic model of economic equilibrium. We solve a question regarding this model that was open for a long time. We provide arguments yielding a complete proof of Dynkin's existence theorem for equilibrium paths.

The strong Whitney topology on the sets of maps of smooth manifolds induces a topology on the set of preferences in euclidean space. We prove that the obtained space is not connected which implies that there is no continuous social choice function defined on a finite power of this space. We also...

In the framework of economics models with unbounded short sales a number of different conditions limiting arbitrage opportunities have been introduced. Dana, Le Van and Magnien [JET.87(1999)169] appeal to the condition of compactness of the individually rational utility set and show that all...

In this note we consider a general equilibrium model with oligopolistic competition between firms who ignore the feedback effect of their dividend payments on demand. The outcome of this competition coincides with the perfectly competitive equilibrium solution, provided that firms have identical...

In this paper we analyze, from the Negishi approach the concepts of structurally stable and structurally unstable economies on Banach's spaces. With this purpose we formalize the intuitive concept of similar economies. We show that in certain cases similar (or neighboring) economies can show no...
