Over the 1990s, the share of foreigners entering the US high-skill workforce grew rapidly. This migration potentially had a significant effect on US workers, consumers and firms. To study these effects, we construct a general equilibrium model of the US economy and calibrate it using data from 1994 to 2001. Built into the model are positive effects high skilled immigrants have on innovation. Counterfactual simulations based on our model suggest that immigration increased the overall welfare of US natives, and had significant distributional consequences. In the absence of immigration, wages for US computer scientists would have been 2.6% to 5.1% higher and employment in computer science for US workers would have been 6.1% to 10.8% higher in 2001. On the other hand, complements in production benefited substantially from immigration, and immigration also lowered prices and raised the output of IT goods by between 1.9% and 2.5%, thus benefiting consumers. Finally, firms in the IT sector also earned substantially higher profits due to immigration.

We characterize what features make supply chains more resilient. Using new data on the universe of firm-to-firm transactions from an Indian state, we identify firms with larger supplier risk following the Covid-19 lockdowns. Using an event-study design we find firms with suppliers in strict-lockdown districts experienced 4.5pp higher separation rates (a 15% increase relative to baseline). We study which characteristics increase supply-chain resilience. Firms that buy more complex products, with fewer available suppliers, are less likely to break links. We explore how firms change post-shock supplier composition. Firms with higher supplier risk form new links with larger and better-connected suppliers.

À l’image de la mosaïque qui lui donne son titre, cet ouvrage assemble les éléments d’un motif laissant à l’espace méditerranéen une place centrale. Combinant les approches, entrecroisant trajectoires individuelles et destins collectifs, il donne à voir le rôle structurant des villes dans la façon de concevoir et représenter l’espace, témoigne des réussites et des échecs du vivre ensemble. Dans une perspective d’anthropologie historique, il interroge la question de la souffrance des corps au travail et des corps asociaux. Il joue enfin sur les échelles de la mémoire, questionnant l’action des institutions et des hommes comme passeurs de culture, mettant en évidence l’importance du phénomène de la circulation au sein d’un espace marqué par un incessant va-et-vient de civilisations dont l’extrême enchevêtrement a fini par donner naissance à une certaine forme d’homogénéité.
