The theory of the rm suggests that firms can respond to poor contract enforcement by vertically integrating their production process. The purpose of this paper is to examine whether firms' integration opportunities affect the way institutions determine international trade patterns. We find that...

Recent empirical evidence suggests that prices for many goods and services are higher in larger markets. This paper provides an explanation for this phenomenon when firms can choose how much to differentiate their products in a monopolistically competitive environment. The model proposes that...

Empirical evidence shows that R&D spending is highly correlated with firm productivity, highly concentrated among large firms, and responsive to trade liberalization. This paper develops a model of product upgrading with heterogeneous firms that captures these characteristics by allowing firms...

This paper develops a theoretical model of trade and environmental emissions with heterogeneous firms, where firms make abatement investments and thereby affect their level of emissions. We show that investments in abatement are positively related to firm productivity and firm exports, while...

This paper compares the effect of economic integration on industry location for a small country that goes ahead with an integration process, such as the European, and a country adopting a wait and see strategy. Theoretical results, derived from a three-region new economic geography model, are...

This paper modifies the heterogenous firms and trade model by Melitz (2003) by explicitly modelling the beachhead cost of a firm in a new market as a function of market size. This leads to several new predictions compared to the standard model. In particular, the productivity of non exporters...

A simple N-country specific-factor model with imperfectly mobile labour is developed. It is shown that effects of country-specific productivity shocks hitting a small country are fundamentally asymmetric. A positive shock will be accomodated by a moderate wage increase and sizable in-migration,...

This paper first presents stylised evidence showing how the date of the introduction of competition policy is correlated with country size. Smaller countries tend to adopt competition policy later. We thereafter present a simple theoretical model with countries of different size and firms...

The standard race-to-the-bottom result is curious in one respect. If a nation wants to attract foreign capital, providing the optimal level of public amenities (and thus charging the optimal tax rate) would seem optimal. This conjecture fails in the standard tax competition model since foreign...

Many countries devote a large part of their national budget to regional policy. This paper analyses the interaction of economic integration and some typical regional policies in a new economic geography model with three regions of different size. The policies analysed are the relocation of...
