This paper compares, in a polluting oligopoly, an emission tax and a form of environmental policy called voluntary agreement (va). The output contraction resulting from the tax amplifies the distortion due to imperfect competition making the tax sub-optimal. The va studied here is a...

This article studies the effects of a commodity tax on consumption and production behaviours in a green market and its implications for welfare components. The analysis rests on a review of vertical differentiation models assuming an ecological awareness of consumers. We distinguish two classes...

We show that labour market institutions, and particularly employment protection are an important determinant of migration flows. Contrary to the popular wisdom, migrants are not attracted by more protective legislation. On the contrary, we show that the employment protection differential acts as...

We propose an econometric analysis of the distributive impact of trade flows, foreign direct investment (fdi), official aid and migrants? remittances. Results suggest that fdi increases inequality, while remittances tend to reduce inequality. Trade and aid have a non-linear relationship with...

This paper studies the effects of the last enlargement of eu on European social heterogeneity, and examines the size of outsourcing to ceecs in relation with national social systems. We use principal component factor analysis and hierarchical classification to represent numerous relations...

This note focuses on the design of prevention programmes and the role of tort law regarding the control of risky activities, associated with unknown or imperfectly known risks, such as innovation or (long term) environmental damages. Together with the existence of perception bias on the side of...

The new lru law (loi relative aux libertés et responsabilités des universités) changed the structure of power within the French university system. Prior to this law, the President of a university was elected by the members of three governing bodies: i) the board of directors, ii) the...

In this paper, we will re-examine the problems linked to the management of environmental risks and reassert the distinction made by Knight [1921] between « risk » and « uncertainty ». Taking into account this uncertainty in a formal way is totally justified for the analysis of environmental...

The purpose of this paper is to analyze the apportionment of seats in intercommunal structures in the Val-d?Oise region. We compare the observed distribution of the seats to a theoretical one obtained with the Webster?s method (or Saint-Laguë?s method). This comparison is made using the most...

We compare the optimal insurance contribution rate and welfare levels for two opposite social insurance systems: a beveridgean one and a bismarckian one. The social contribution rates are decided by majority voting rule in both cases. In a model where agents earn heterogeneous incomes, we...
