- BOEHM Johannes (SciencesPo) : Trade and the End of Antiquity
- Thomas Chaney
- RésuméWhat caused the end of antiquity, the shift of economic activity away from the Mediterranean towards Northern Europe? Henri Pirenne (1939) proposes that it was caused by the disruption of trade linkages following the Arab conquests of Northern Africa and Iberia by the Arabs and the associated loss of Byzantine naval power in the Western Mediterranean. To test the ‘Pirenne Thesis’ we assemble a large database of coin flows between the 4th and 10th century which we study through the lens of a dynamic gravity model of trade. Coins gradually diffuse alongside trade linkages. Coins contain information on the date and place of minting, which allows us to reconstruct trade flows from data on the spatial and temporal distribution of coins found in coin hoards. We estimate changes in trade costs arising from changing political and religious borders following the Arab conquests. Border effects can explain the relative decline of the eastern Mediterranean, but not the increased urbanization in Muslim Spain and in the Frankish lands. These patterns can be explained when we further account for technological change and for increased mint output. The estimated model points to the large effects that geopolitical changes can have by disrupting long-distance trade.

- PRAETORIUS Sophie (Science Po) : Collaboration in Technology and Multinational Production
- RésuméThis paper studies how inter-firm collaboration in technology relates to global production choices. Building a structural multinational production model that incorporates technology choices and allows for collaboration when choosing the optimal assembly location for a given variety that is sold in a specific destination market, I find that both technology choice and sharing of platforms as input technology have important effects on the cost, and, thus, the expected profits of firms. Conditional on technology, a firm’s cost of serving a market increases by 1% compared to a scenario where firm choices are agnostic to input technology. On the other hand, allowing for collaboration reduces their cost by 4%. These effects propagate through the firm’s entry choices and, thus, shape the global production landscape

- ANDRIEU Elodie (PSE) : Multi-establishment Firm Structure, Subsidies and Spillovers
- John Morrow
- RésuméHow do firms diffuse resources, and does this result in spillovers far from headquarters? We show subsidies induce French firms to hire new workers, mainly in new establishments and often in new commuting zones, with little evidence of reallocation. The most hiring responsive occupations are techies and support workers in line with R&D targeting. We estimate a subsidy employment spillover elasticity of .11 at the commuting zone level within industry, but weak effects in the commuting zone. Dispersed industries have half this elasticity and concentrated industries twice this elasticity. While subsidies are awarded to headquarters in advanced areas, firms redistribute effects more broadly.
