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 short paper employs individual voting records of the Monetary Policy Committee (MPC) of the Bank of England to study heterogeneity in policy preferences among committee members. The analysis is carried out using a simple generalization of the standard Neo Keynesian framework that allows...

It is not uncommon that a society facing a choice problem has also to choose the choice rule itself. In such situation voters’ preferences on alternatives induce preferences over the voting rules. Such a setting immediately gives rise to a natural question concerning consistency between these...

This paper studies the theoretical and empirical implications of monetary policy making by committee under three different voting protocols. The protocols are a consensus model, where super-majority is required for a policy change, an agenda-setting model, where the chairman controls the agenda,...

In this paper we compare the welfare effects of unemployment insurance (UI) with an universal basic income (UBI) system in an economy with idiosyncratic shocks to employment. Both policies provide a safety net in the face of idiosyncratic shocks. While the unemployment insurance program should...

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...
