The objective of this paper is to analyze the efficiency and equity consequences of the implementation of an environmental tax. Do the two purposes collide or can they be simultaneously achieved? Using results of the related literature, we show that precise conditions have to be met in order to...

This paper analyzes the environmental tax policy issues when labor is heterogeneous. The objective is to assess whether an environmental tax policy could be Pareto improving, when the revenue of the pollution tax is recycled by a change in the labor tax properties. We show that, depending on the...

The double dividend literature studies the simultaneous pursuit of two objectives: improved quality of the environment through the implementation of an environmental tax (first dividend) and increased social welfare by reducing overall tax distortions (second dividend). This paper investigates...

This paper examines the welfare of consumers in an incomplete markets economy with extrinsic uncertainty. It is shown that the utility of one consumer may be minimized at the Walrasian allocation relative to all other equilibrium allocations for a given security structure. Thus, this consumer...

This paper identifies the most restrictive limit that rules of origin can enforce and still continue to guarantee gains from trade area formation in general settings. Many commonly used rules of origin exceed this condition in practise. Second, free trade areas generally involve unharmonized...

We show that the entry of a second firm in a horizontally differentiated market (ala Hotelling) may harm consumers as prices increase and consumer's surplus possibly decrease. We first derive the price and the consumer's surplus of a monopoly which is located at the center of the market. When a...
