About & CV

Joacim_1_130x190My research is focused on using Swedish registry data to analyze policy relevant topics in entrepreneurship, finance, and labor economics. A central theme is the economics of corporate ownership, i.e. how the real economy is affected by different corporate ownership forms. I thus study things like the decision to become a business owner, venture capital investments, listing/delisting decisions, private equity buyouts, and M&As. I have also done theoretical work on ownership changes and on how to regulate the media, telecommunications, and IT industry. My research has been published in journals such as the Journal of Labor Economics, European Economic Review, and the International Journal of Industrial Organization.
