We study the role of firm heterogeneity and imperfect competition for global production networks and the gains from trade. We develop a quantifiable trade model with two-sided firm heterogeneity, matching frictions, and oligopolistic competition upstream. More productive buyers endogenously...

Recent disruptions to global value chains (GVCs) have raised an important question: Can decoupling from GVCs increase a country’s welfare by reducing its exposure to foreign supply shocks? We use a quantitative trade model to simulate GVCs decoupling, defined as increased barriers to global...

We study how technology adoption and changes in global value chain (GVC) integration jointly affect labor shares and business function specialization in a sample of 14 manufacturing industries in 14 European countries in 1999-2011. Our main contribution is to highlight the indirect effect of...

Measured by trade in intermediate inputs, economic integration has increased between 2000 and 2014 between members of the European Union and even more with non-members. Integration is negatively related to economic size and positively to the number of years as a member. Germany is the largest...

Geo-political tensions and disruptions to global value chains have led policy makers to re-evaluate their approach to globalisation. Many countries are considering friend-shoring - trading primarily with countries sharing similar values - as a way of minimising exposure to weaponisation of trade...

This paper studies how firms' offshoring decisions shape a country's domestic production networks. We develop a model in which heterogeneous firms source inputs from multiple industries located in different domestic regions and foreign countries. Input sourcing entails communication with...

With the availability of international value added trade data it has become evident that gross export data and value added data do not provide the same information. Although gross exports crosses national borders and is the target of trade policy, value added data tell us what fragment in the...

Production processes are increasingly organized in international value-chain networks. The involved firms can be operating at arm’s length or be vertically integrated. Both the incidence and the direction of integration (backward or forward in the value chain) depend on specific...
