We study the impact of FDI on the productivity of host-country firms. FDI has positive spillovers only when foreign and domestic firms use similar technologies. Channeling FDI to sectors where firms share similar technology would significantly increase productivity spillovers from FDI. We show...

This paper estimates the effect of relaxing the social insurance mandate on entrepreneurial activity. We use a unique discontinuity in Finland that allows certain entrepreneurs not to pay social insurance contributions on their income. Using rich administrative data, we find that relaxing the...
