Working Papers​​​

Marriage Among European Nobility 2017, with Jerôme Pouyet and Thomas Tregouet 
This paper analyzes marriage and union patterns in the European nobility, starting from the 11th century. We find that Germans were most likely to marry same-title spouses rather than British. Moreover, this pattern is decreasing over time. We discuss these results in view of matching theory. Our data and the historical background provide information on a marriage market where we can reasonably assume complete information, and simple ordered preferences on titles. Theory then predicts that a higher degree of transferability or more complex preferences make assortative mating less likely. Historical evidence supports both assumptions: it was easier for a rich noble of lower rank to marry upward in England than in ancient Germany; over the centuries, other considerations than the title began to influence marital decision.​​​

The Geography of Social Change 2017, with Alessandra Fogli 
We investigate how and when social change arises. We use data on the spatial diffusion of the fertility transition across US counties to identify the contribution of coordination and learning in the emergence of a new family model. We provide several measures of local and global spatial correlation to establish the existence of a significant geographic pattern in the data. We propose a mechanism in which cultural assimilation is the engine of the fertility transition. Using Census data starting from 1850, we estimate the speed of fertility assimilation for the different ethnic groups to show that their process of convergence is a crucial channel to explain the aggregate decline of fertility rate over time and across space.

Welfare and Trade Margins with Multinational Production 2017, with P. Bombarda
We examine how the presence of heterogenous multinational firms matters for the aggregate welfare implications of trade by comparing models with only export, intra-firm activity, and pure multination production. We show that extensive margins depend on both supply and demand parameters, and are not longer constant. We use a theoretical comparative static to isolate the additional component of wel- fare associated with intra-firms trade and to show that models of multinational production have new aggregate welfare implications. The model is then calibrated to analyze counterfactual scenarios. We find that truncation through multinational production is associated with the largest welfare gains from liberalization.​ ​

​​Intra-Firm Trade, Multinational Production, and Welfare 2016, with Pamela Bombarda​​
We propose a model where firms have access to competing market strategies: export and multinational production. Due to technological appropriability issues, foreign affiliates import an intermediate input from the home headquarters. The presence of export and multinational production alters the standard results obtained for welfare in heterogeneous firm models, through a double truncation of the productivity distribution. The model is then calibrated to analyze counterfactual scenarios. We find that welfare gains from intra-firm trade range from 0.3 to 7 percent depending on country characteristics.​​
