International monetary policy trilemma-the tradeoff among exchange rate stability, monetary independence, and unrestricted capital mobility-is an important constraint for policy makers in an open economy. This paper investigates an aspect of the hypothesis that has received relatively less attention: whether a decrease in capital mobility through imposition of capital controls, while holding the degree of exchange rate stability constant, will enhance monetary independence. Using a panel dataset covering 88 countries for the 1995-2010 period and the generalized method of moments (GMM) estimation, we find that: (1) capital controls help improve a country's monetary independence; (2) the effectiveness of capital controls depends on the types of assets and the direction of flows that are imposed; and (3) the choice of exchange rate regime has an important impact on the effectiveness of capital controls on monetary independence.

This paper aims to examine the macroeffects of exchange rate movements on a wide array of real economic variables in the US in a unifying model. By employing the non-linear factor-augmented vector autoregressive (FAVAR) model with simulation methods, we could trace the effects of exchange rate appreciation and depreciation on a wide array of macroeconomic variables through the impulse response function (IRF). The main findings are: (1) In response to dollar depreciation, import price index (IMP), producer price index (PPI) and CPI increase significantly. The pass-through ratio declines along the distribution chain. (2) Merchandise trade balance, current account balance and output improve facing dollar depreciation. (3) Savings decreases in response to dollar depreciation. (4) Employment and average hourly earnings increase in times of exchange rate depreciation and vice versa. The effects on macroeconomy from appreciation and depreciation seem symmetric. Many other interesting findings are also documented.
