About & CV

Joacim_1_130x190My research is focused on using Swedish registry data to analyze policy-relevant topics in entrepreneurship, corporate finance, and labor economics. A central theme is the economics of corporate ownership. I thus study topics like the decision to become a business owner, private equity investments, listing and delisting decisions, and M&As. I also research the careers of successful people, and I have done work on how to regulate telecommunications and media companies. My research has appeared in, among others, the Journal of Labor Economics, European Economic Review, and the International Journal of Industrial Organization. It has also been featured in major newspapers such as The Economist, Dagens Nyheter, Svenska Dagbladet, and Helsingin Sanomat.
