Extensive work has been done to assess the role played by externalities in policy interventions. Studies dealing with this issue in experimental settings abound in the literature. Much less attention, however, has been devoted to the case when data comes from observational studies. In this...

In this paper we analyze where value is added along supply chains on a sample of more than 2 million of firms in the European Union. We detect a non-linear U-shaped relationship between the value added generated by firms and their position on a productive sequence, for which tasks at the top and...

In this paper we study the organization of Global Value Chains on a sample of about 4,000 manufacturing parent companies operating more than 90,000 affiliates on a global scale, which chose to integrate at least once in the period 2004–2012. Assuming a technological sequence of production...

This paper analyzes the participation of North African countries into international production networks and examines if/to what extent being part of a global value chain affects firms' performance. Using largely unexploited Input-Output data from UNCTAD-Eora, we describe regional and country GVC...

Backward and forward vertical integrations both shape the organization of Global Value Chains (GVCs). Yet, many studies make the unrealistic assumption that integration decisions are binary and one-directional, i.e., companies make the integration decision only once and they can go either...

We study the effect of conflict on firms’ economic performance and explore the underlying mechanisms. Combining an original panel dataset of Libyan firms with geolocalized data on conflict events, we build a firm-specific measure of conflict exposure and use its within-firm variation to show...
