Sabemos muy bien el papel que cumplieron los inmigrantes en el progreso de nuestro país y región, sobre todo por el conocimiento que traían de ciertas habilidades y profesiones. Es lo que trata este trabajo: “The Role of Immigrants, Emigrants, and Locals in the Historical Formation of Knowledge Agglomerations” por Philipp Koch y, Viktor Stojkoski, Université de Toulouse, † y César A.

“Did migrants help make Paris a center for the arts and Vienna a beacon of classical music? Or was the rise of these knowledge agglomerations a sole consequence of local actors? Here, we use data on the biographies of more than 22,000 famous historical individuals born between the years 1000 and 2000 to estimate the contribution of famous immigrants, emigrants, and locals to the knowledge specializations of European regions. We find that the probability that a region develops a specialization in a new activity (physics, philosophy, painting, music, etc.) grows with the presence of immigrants with knowledge on that activity and of immigrants specialized in related activities. We also find that the probability that a region loses one of its existing areas of specialization decreases with the presence of immigrants specialized in that activity and in related activities. In contrast, we do not find robust evidence that locals with related knowledge play a statistically significant role in a region entering or exiting a new specialization. These findings advance our understanding of the role of migration in the historical formation of knowledge agglomerations.”
