I develop a theoretical model in which scientists move across a network of scientific sectors. The mobility of a scientist t o a new sector leads to knowledge diffusion in the economy\, but it can sim ultaneously hurt the sector the scientist leaves\, which loses a potentiall y productive researcher. I show that there exists an optimal level of scien tists’ mobility and that the structure of the network is crucial for know ledge diffusion and long-run growth. I then relate the model’s prediction s to the observed differences in the slowdown of productivity and output gr owth in Europe relative to the United States. In the model\, a more flexibl e labour market with higher turnover (more job switching) can generate fast er growth than a more rigid labour market with low mobility. The novel poli cy implication is to highlight how tools from labour economics—such as un employment insurance design\, training programs\, labour-market regulations \, and contractual arrangements—can be powerful levers for innovation pol icy.**This paper studies coordination over a focal issue -women’s voting rights- within a constituency heterogeneous along a given dimension (e.g.\, income)\, and how it responds to collective action on a second\, dimension -aligned issue - labor rights. The setting is early-20th-century France\, d uring the emergence of an organized women’s suffrage movement. I assemble a commune-by-year panel of local membership in the national suffrage assoc iation (1909-1940) paired with measures of unionization and striking activi ty (1884-1940). I first document some stylized facts about the organization al capacity\, dynamics\, and efficiency of the suffrage movement. I then es timate its relationship to the labor movement using a Bartik-style shift-sh are instrumental-variables strategy for changes in local unionization patte rns. In subsequent iterations\, I develop a collective-action framework in which agents endowed with two traits allocate finite resources across two i ssues\, yielding testable implications for cross-issue spillovers and coord ination.\\n\\nContact: Xavier Chatron-Colliet: xavier.chatron-colliet[at]un iv-amu.frArmand Rigotti: armand.rigotti[at]univ-amu.fr\n\nPlus d'informati ons: https://amse-aixmarseille.fr/en/events/elad-passi-olivia-tsoutsoplidi- LOCATION:MEGA - Salle Carine Nourry\, 424\, Chemin du Viaduc\, 13080 Aix-en -Provence URL;VALUE=URI:https://amse-aixmarseille.fr/en/events/elad-passi-olivia-tsoutsoplidi-0 CONTACT:Xavier Chatron-Colliet: xavier.chatron-colliet[at]univ-amu.frArmand Rigotti: \;armand.rigotti[at]univ-amu.fr TRANSP:OPAQUE END:VEVENT END:VCALENDAR
