There is no single event with such importance for the Baltic Region as Russia’s war on Ukraine. The reconstruction, when the war eventually ends, will require enormous investments. To do that efficiently and with a minimum of corruption, there is an urgent need for data, solid analysis, and reform proposals based on credible scientific methods. This project, a continuation and deepening of an effort that started already in March 2022 and emanating in a widely cited report on the reconstruction of Ukraine by Gorodnichenko et al. (2022), aims to produce exactly this. For that purpose we have gathered a prominent and experienced international research team with core faculty from the Kyiv School of Economics, the Stockholm Institute of Transition Economics at the Stockholm School of Economics, and Södertörn University. The team is also closely connected to a network of research institutes across seven countries in Eastern Europe and around the Baltic Sea, and to a group of world leading economists contributing to the book mentioned above. In this project we focus on four key areas of reconstruction highlighted in the report that match with the team’s special competencies: i) sustainable urban development; ii) the nexus of procurement, corruption, and markets; iii) public opinion and conflict intensity; and iv) supporting agricultural resilience and global food security. The project will produce numerous research papers of great value both academically and for policy purposes.
