We extend the Benassy (1996) 'taste for variety' model to an open economy setting. With the Benassy effect, the market equilibrium is inefficient, openness reduces the varieties provided in the unconstrained optimum and there are potential gains from international coordination. -- Taste for...

We present a unified dynamic framework to study the interconnections between international trade and business cycle models. We prove an aggregate equivalence between a competitive, representative firm model that has aggregate production externalities and dynamic trade models that feature...

We provide an overview of several approaches to modeling market structure in multisector general equilibrium (MSGE) models, including both oligopoly and monopolistic competition. We emphasize open economy models and applications to international economic policy. We map out practical strategies...

Entrepreneurs who decide to enter an industry are faced with different levels of effective entry costs in different countries. These costs are heavily influenced by economic policy. What is not well understood is how international trade affects the government incentive to impact on entry costs,...

The paper examines policy externalities between imperfectly competitive open economies where unemployment prevails in general equilibrium. We develop a two-country and two-sector model with monopolistic competition in the goods market and wage bargaining in the labor market. Policy externalities...

This paper develops an open economy firm-heterogeneous model where the combination of market rigidities and exchange rate uncertainty acts like a barrier to trade and modifies a firm's optimal choice in terms of production and pricing. The existence of price and labor rigidities, coupled with...

When the world economy was recently hit by a severe recession, governments all over the world reacted by initiating stimulus packages. Some countries (among them, most notably, China and the US) tried to put special emphasis on their home industries by including "Buy local" clauses into the...

This paper studies a model of the distribution of income under bounded needs. Utility derived from any given good reaches a bliss point at a finite consumption level of that good. On the other hand, introducing new varieties always increases utility. It is assumed that each variety is owned by a...
