Do corporate tax cuts increase investments?

This paper studies the effect of corporate taxes on investment. Using firm-level data on German corporations, we investigate the 2008 tax reform that cut corporate taxes by 10 percentage points. We expect heterogeneous investment responses across firms, since firms with a foreign parent have more cross-country profit shifting opportunities than domestically owned firms. Using a matching difference-in-differences approach, we show that, following the corporate tax cut, domestically owned firms increased investments to a larger extent than foreign-owned firms. Our results imply that corporate tax changes can increase corporate investment but have heterogeneous investment responses across firms.
