This paper investigates the impact of capital controls on business cycle fluctuations and welfare. To perform this analysis, we deploy an asymmetric two country model that is subject to negative foreign interest rate shocks. The results show that both an inflow and outflow capital control are able to attenuate capital flow dynamics, but each control bears different implications for macroeconomic outcomes. Whilst the outflow capital control is associated with shock attenuation benefits, the inflow capital control is shown to amplify the impact of shocks. Easier capital control regimes enhance the attenuation and amplification properties associated with each capital control, whilst strict regimes do the opposite. Lastly, the analysis shows that the welfare effects of capital controls are agent dependent, and that society prefers the outflow capital control to the inflow capital control. Taken together, these results are indicative of the comparative desirability of capital controls imposed on the financial sector (outflows) as compared to the real sector (inflows).
