We examine the first widespread use of capital controls in response to a global or regional financial crisis. In particular, we analyze whether capital controls mitigated capital flight in the 1930s and assess their causal effects on macroeconomic recovery from the Great Depression. We find evidence that they stemmed gold outflows in the year following their imposition; however, time-shifted, difference-indifferences (DD) estimates of industrial production, prices, and exports suggest that exchange controls did not accelerate macroeconomic recovery relative to countries that went off gold and floated. Countries imposing capital controls also appear to perform similar to the gold bloc countries once the latter group of countries finally abandoned gold. Time series regressions further demonstrate that countries imposing capital controls refrained from fully utilizing their newly acquired monetary policy autonomy. Even so, capital controls remained in place as instruments for manipulating trade flows and for preserving foreign exchange for the repayment of external debt.* We thank conference and seminar participants at Oxford University, UC Davis, and the Bank of Norway-Graduate Institute of International Studies Conference for useful suggestions.
