The real effects of capital controls

In aftermath of the global financial crisis of 2008-2009, emerging-market governments have increasingly restricted foreign capital inflows. The data show a statistically significant drop in cumulative abnormal returns for Brazilian firms following capital control announcements. Large firms and the largest exporting firms appear less negatively affected compared to external-finance-dependent firms, and capital controls on equity have a more negative announcement effect than those on debt. Real investment falls following the controls. Overall, the results suggest that capital controls segment international financial markets, increase the cost of capital, reduce the availability of external finance, and lower firm-level investment.
