In particular, we examine the case of the Alexander von Humboldt Professorship (AvHP) programme, which - since 2008 - offers substantial funding to top scholars willing to move from abroad to a German university. Based on a difference-in-differences approach, we test whether the university departments that recruit an AvHP recipient increase the number of internationally co-authored publications and the recruitment of new, high-quality researchers from abroad. Results are very heterogeneous across broad scientific fields, with a significant and positive effects in the Social sciences and null or negative results in all others.23 p.application/pdfeng(c) Associazione Amici di Economia e Politica Industriale, 2024http://creativecommons.org/licenses/by/3.0/es/Premis científicsInvestigadorsAprenentatge per descobrimentPolítica científicaContractes de recerca i desenvolupamentScience awardsResearch workersLearning by discoveryScience and stateResearch and development contractsinfo:eu-repo/semantics/article7568332025-05-06info:eu-repo/semantics/openAccess
