This project studies collaboration in highly skilled, nationally diverse teams. An unexpected international political conflict makes national diversity more salient among existing and potential team members. I exploit this natural experiment to quantify the role of social, identity-driven, costs for performance and formation of diverse teams. Using microdata from GitHub, the world's largest hosting platform for software projects, I estimate the causal impacts of a political conflict that burst out between Russia and Ukraine in 2014. I find that the conflict strongly reduced online cooperation between Russian and Ukrainian programmers. The conflict lowered the likelihood that Ukrainian and Russian programmers work in the same team and led to the performance decline of existing joint projects. I provide evidence that the observed effects were not driven by economic considerations. Rather, the conflict activated national identities and shifted programmers' taste for teammates and projects. My results highlight the role of identity-driven concerns that can distort existing and prevent future collaborations, otherwise profitable from an economic perspective.

Does the emigration of skilled individuals necessarily result in losses for source countries due to the brain drain? Combining industry-level patenting and migration data from 32 European countries, we show that emigration in fact positively contributes to innovation in source countries. We use changes in the labour mobility legislation within Europe as exogenous variation to establish causality. By analysing patent citation data, we further provide evidence that these positive effects are driven by knowledge flows that are triggered by emigrants. While skilled migrants are not inventing in their home country anymore, they contribute to cross-border knowledge and technology diffusion and thus help less advanced countries to catch up to the technology frontier.

This Research Paper is a contribution to a wider cost-of non-Europe assessment in the Area of Freedom Security and Justice requested by the European Parliament's Committee on Civil Liberties that can be found here. The research takes stock of the state of play in European Union cooperation in the area of legal immigration. The Research Paper identifies gaps and barriers of current sectorial and fragmented EU legal immigration acquis. It assesses their economic impacts and impacts at individual level in terms of fundamental rights protection and non-discrimination laid down in international, regional and EU human rights and labour standards. The research highlights the need for 'more EU' in upholding equal treatment standards between third country workers with EU nationals in relation to working and living conditions. The Research Paper elaborates on the potential benefits, cost drivers and feasibility of different policy options for the EU ranging from: better enforcement, to the gradual extension of EU legislation towards other labour market sectors or bringing back to the idea of a Binding Immigration Code. The research concludes that EU internal market, national administrations as well as EU and Third Country Citizens would benefit from more homogenous policy approach in the area of legal migration.

How can the responsibility for refugees be distributed more fairly – globally and within the EU? And how can we curb irregular migration while expanding legal immigration to the benefit of all concerned? The large number of refugees and other migrants who have come to Europe over the last two years has caused the EU member states that received most of the asylum seekers, to reach their capacity limits. With a view to new arrivals and their long-term integration, it is now necessary to develop new and, above all, common strategies to address the migration flows to Europe. The '2017 MEDAM Assessment Report' focuses on two core Messages: - Distribute the responsibility for refugees more equitably. - Extending legal immigration from non-EU Member States into EU member states. ; Wie kann die Verantwortung für Flüchtlinge weltweit und in Europa gerechter verteilt werden? Und wie können wir irreguläre Einwanderung eindämmen und gleichzeitig die legale Einwanderung zum Nutzen aller Beteiligten fördern? Durch die große Zahl an Flüchtlingen und andere Migranten, die Europa in den vergangenen beiden Jahren erreicht haben, wurden insbesondere jene EU-Staaten, die die meisten Asylsuchenden aufgenommen haben, an ihre Kapazitätsgrenzen gebracht. Mit Blick auf weitere Neuankömmlinge und deren langfristige Integration ist es nun notwendig, neue und vor allem gemeinsame Strategien zur Bewältigung der Flüchtlingsströme nach Europa zu erarbeiten. Im Fokus des "2017 MEDAM Assessment Report on Asylum and Migration Policies in Europe" stehen zwei Handlungsempfehlungen: - Die Verantwortung für Flüchtlinge weltweit und in Europa gerechter verteilen. - Die legale Einwanderung von außerhalb der EU in EU-Mitgliedstaaten erleichtern.

The EU faces major challenges in asylum and migration policy: reorganize the EU asylum system, secure the external border, curb irregular immigration through cooperation with African governments, and support developing countries that host large numbers of refugees from Syria and elsewhere. These challenges are inter-connected and require a comprehensive approach with broad support by all EU member states. However, member states are affected by immigration in substantially different ways and the political preferences of policy makers and voters also vary widely–necessitating implementable proposals to overcome the EU's asylum and immigration impasse. In the '2018 MEDAM Assessment Report', we propose a comprehensive strategy for EU asylum and immigration policies that is both politically feasible and effective, based on the concept of flexible solidarity between EU member states. ; Die EU steht vor großen Herausforderungen in der Asyl- und Migrationspolitik: Reform des EU-Asylsystems, Sicherung der Außengrenzen, Begrenzung der irregulären Einwanderung durch die Zusammenarbeit mit afrikanischen Regierungen sowie Unterstützung von Entwicklungsländern mit einer großen Zahl an Flüchtlingen. Diese Herausforderungen sind miteinander verwoben und erfordern nicht nur einen ganzheitlichen Ansatz, sondern auch die breite Unterstützung aller EU-Mitgliedsstaaten. Dabei sind diese in unterschiedlicher Weise von Einwanderung betroffen, und auch die politischen Ansichten der Entscheidungsträger und Wähler unterscheiden sich erheblich. Es bedarf umsetzbarer Vorschläge, um den aktuellen "Stillstand" in der Asyl-und Migrationspolitik der EU zu überwinden. Im "2018 MEDAM Assessment Report on Asylum and Migration Policies in Europe" schlagen wir eine ganzheitliche Strategie für die EU-Asyl-und Migrationspolitik vor, die sowohl politisch machbar ist als auch auf dem Konzept der flexiblen Solidarität zwischen EU-Mitgliedsstaaten beruht.
