Almost twenty-five years after the appearance of Dixit and Stiglitz’s paper on monopolistic competition and optimum product diversity, I try to take stock of the progress which has been made in applying their approach to international trade theory. I review the principal applications to trade...

I briefly review the empirical evidence in the trade and wages debate, which overwhelmingly rejects the Heckscher-Ohlin explanation for recent increases in OECD skill premia. I then argue that the same evidence is also difficult to reconcile in general equilibrium with the view that exogenous...

The theory of strategic trade policy yields ambiguous recommendations for assistance to exporting firms in oligopolistic industries. However, some writers have suggested that investment subsidies are a more robust recommendation than export subsidies. We show that, though ambiguous in principle,...

I review and extend three approaches to trade and environmental policies - competitive general equilibrium, oligopoly and monopolistic competition. The first two have surprisingly similar implications - deviations from first-best rules are justified only by constraints on policy choice (which...

I explore the interactions between comparative, competitive and absolute advantage in a two-country model of oligopoly in general equilibrium. Comparative advantage always determines the direction of trade, but both competitive and absolute advantage affect resource allocation, trade patterns...

This paper introduces a symposium of EEA-funded studies that evaluate economics research in Europe. The paper considers some general issues in evaluations, paying special attention to the problem of selecting journal weights, and notes some special features of the individual studies. Despite...

This paper analyses inequality in Ireland via a decomposition of the Gini coefficient by source of income. Using data from the Irish Household Budget Survey of 1987, seventeen components of disposable income are identified and their contribution to inequality evaluated. Their contribution to...

We introduce an index of trade policy restrictiveness defined as the uniform tariff which maintains the same trade volume as a given tariff/quota structure. Our index overcomes the problems of the trade-weighted average tariff - it avoids substitution bias, correctly accounts for general...
