Does going public in the US facilitate corporate innovation of foreign firms?

We examine how going public in the U.S. IPO market influences corporate innovation. Using 185 foreign and 2948 U.S. domestic firms going public in the U.S. over the 1980-2006 period, we find that while exhibiting similar innovativeness in the pre-IPO period, non-U.S. firms tend to generate more innovation than U.S. domestic firms after going public. The findings are robust to adopting subsample tests, various measures of changes in innovation around the year of the IPO, and accounting for truncation problems and potential endogeneity concerns. Further tests show that changes in innovation around the year of the IPO tend to be less prominent for non-U.S. firms that domiciled in countries with more developed equity market and higher level of economic freedom. Our study provides insights into the real effect of going public in the U.S. IPO market on innovative activities.
