This paper explores the quantitative consequences of transatlantic trade liberalization envisioned in a Transatlantic Trade and Investment Partnership (TTIP) between the United States and the European Union. Our key innovation is to develop a new quantitative spatial trade model and to use an...

This paper uses the quantitative spatial model with heterogeneous locations linked by costly goods trade, migration and commuting developed in Monte et al. (2018) to address the workings of local labor markets in Germany. One key contribution concerns the analysis of the role of the expenditure...

In this paper we investigate the causal effect of immigration on trade flows, using Italian panel data covering very small geographical units (NUTS-3). Exploiting the very favorable setup offered by Italy's features - the very high number of countries of origin of immigrants ('super-diversity'),...

In this paper we highlight a new complementary channel to the business and social network effect à la Rauch (2001) through which immigrants generate increased export flows from the regions in which they settle to their countries of origin: they can become entrepreneurs. Using very small-scale...

We investigate whether network closure in the supply chain can explain the heterogeneity observed in import premia. Using unique panel data on trade flows among beef farms in the Italian region of Piedmont, we analyze a purely sequential supply chain characterized by the co-existence of two...

This research explores the historical roots of the division of labor in pre-modern societies. It advances the hypothesis and establishes empirically that intra-ethnic diversity had a positive effect on the division of labor across ethnicities in the pre-modern era. Exploiting a variety of...

This paper is motivated by the fact that, contrary to its importance in practice, the role of land for production has received no attention in the new trade theory and the new economic geography. We set up a simple monopolistic competition model and we show that, due to the factor proportions...

The core-periphery model by Krugman (1991) has two 'dramatic' implications: catastrophic agglomeration and locational hysteresis. We study this seminal model with CES instead of Cobb-Douglas upper tier preferences. This small generalization suffices to change these stark implications. For a wide...

I illustrate that the welfare improvement property of the Melitz model is due to the shape of the aggregate labor demand curve, which slopes upwards. By slightly changing some assumptions in the model, this curve may have a negative slope. In this case, increases in aggregate productivity result...

We introduce a simple oligopolistic trade model with international transportation costs, and analyze the profitability and the social desirability of national vs. international mergers in relation to three different issues, (i) the level of trade freeness, (ii) the possibility of rent...
