We develop a new general equilibrium model of trade with heterogeneous firms, variable demand elasticities and endogenously determined wages. Trade integration favors wage convergence, intensifies competition, and forces the least efficient firms to leave the market, thereby affecting aggregate...

We provide a comprehensive empirical analysis of the links between international services outsourcing, domestic outsourcing, profits and innovation using plant level data. We find a positive effect of international outsourcing of services on innovative activity at the plant level. Such a...

The COVID-19 pandemic has disrupted trade and global value chains. Small open economies such as Portugal are particularly vulnerable. In this paper we consider the impact of the pandemic on the country's exports, arguing that an export-led recovery is possible. The challenge is to identify...

We discuss the effects of offshoring on the labor market in a matching model with endogenous adjustment of educational skills. We carry out a comparative statics analysis and show that offshoring leads to a restructuring of the economy through skill-biased technical change (SBTC) where overall...

The robust empirical finding that exporting firms are systematically different from firms thatmerely serve domestic consumers has inspired the development of a new brand of tradetheory, the theory of heterogeneous firms and trade. The establishment of a canonical modeldue to Melitz (2003) has...

This paper provides a simple theory of geographical mobility which simultaneously explainspeople’s choice of residences in space and the location of industry. Residences are chosenon the basis of the utility which mobile households obtain across locations...

We construct a model of offshoring with externalities and firm heterogeneity. Due to thepresence of externalities, temporary shocks like the Y2K problem can have permanenteffects, i.e., they can permanently raise the extent of offshoring in an industry. Also, the initialadvantage of a country as...

The risk of default that business firms face is very significant and differs widely across countries. This paper explores the links between countries' business conditions and international trade embedment and the default risk at the country level from a theoretical point of view. Our main...

We propose occupational decisions of heterogeneous individuals as an alternative mechanism of explaining the distribution of firm productivities emphasized by empirical studies. Thus, we integrate the frameworks of Melitz (2003), and of Manasse and Turrini (2001) that establish the theoretical...

We develop a general equilibrium model of international trade with heterogeneous firms, where countries can invest into basic research to improve their technological potential. These research investments tighten firm selection and raise the average productivity of firms in the market, thereby...
