This Paper presents a model of international trade that features heterogeneous firms, relative endowment differences across countries, and consumer taste for variety. The Paper demonstrates that firm reactions to trade liberalization generate endogenous Ricardian productivity responses at the...

Despite the fact that importing and exporting are extremely rare firm activities, economists generally devote little attention to the role of firms when discussing international trade. This paper summarizes key differences between trading and non-trading firms, demonstrates how these differences...

This paper formulates a structural empirical model of heterogeneous firms whose workers exhibit fair-wage preferences. In the underlying theoretical framework, such preferences lead to a link between a firm's operating profits on the one hand and wages of workers employed by this firm on the...

We formulate a two-country model with monopolistic competition and heterogeneous firms to reconsider labor market linkages in open economies. Labor-market imperfections arise by virtue of country-specific real minimum wages. Two principal experiments are considered. First, we show that trade...

Relative wages vary considerably across regions of the United Kingdom, with skill-abundant regions exhibiting lower skill premia than skill-scarce regions. This Paper shows that the location of economic activity is correlated with the variation in relative wages. UK regions with low skill premia...

This Paper develops a general test of factor price equalization that is robust to unobserved regional productivity differences, unobserved region-industry factor quality differences and variation in production technology across industries. We test relative factor price equalization across...

We develop a methodology for identifying departures from relative factor price equality across regions that is valid under general assumptions about production, markets and factors. Application of this methodology to the United States reveals substantial and increasing deviations in relative...

This paper uses a full-scale CGE-model - calibrated on 1992 data - to investigate the effects of European integration on the location of industrial production. Our results reveal large differences among individual industries. Industries with high scale elasticities typically display a...

Should R&D policies within an economic union be centralized or decentralized to each individual country? Do non-cooperative policies - typically implying policy competition between countries - always give rise to too high R&D subsidies in a decentralized policy regime? Should small countries...

This paper studies the investment creation and investment diversion effects of the EU's Single Market programme (EU92). We find suggestive, but not conclusive, evidence indicating that EU92 may have led to investment diversion in the economies of the European Free Trade Association (EFTA) and...
