Essays in international finance and central bank policy

This dissertation studies topics in international finance and central bank policy. In the first chapter, "Common idiosyncratic volatility and carry trade returns", I provide new evidence that incomplete consumption risk sharing across countries is an important determinant of carry trade returns. I show that there is a strong co-movement in idiosyncratic volatilities over time, and that shocks to the common idiosyncratic volatility (CIV) factor, defined as the equally weighted average of the idiosyncratic volatilities in the cross-section, are priced. I find that high-interest rate currencies deliver low returns when the CIV increases, which are bad times for investors. Low-interest rate currencies provide a hedge by yielding positive returns. CIV shocks remain an empirically powerful risk factor in explaining the cross-section of carry trade returns after controlling for global foreign exchange (FX) volatility risk. Furthermore, CIV risk is correlated with cross-country income risk faced by households. My findings are consistent with a heterogeneous-agent model with persistent, uninsurable idiosyncratic shocks in consumption growth. The calibrated model quantitatively accounts for the cross-sectional differences in average returns across CIV-beta sorted portfolios for plausible market prices of CIV risk. In the second chapter, "Fed-implied market conditions", we propose a novel text processing technique to extract views of market conditions that are implicit in the Fed's policy statements and minutes. The method is easy to apply and addresses several problems inherent in the use of changes in interest rates as a proxy for central bank policy. First, we project market variables into the text of FOMC statements and minutes (separately) using support vector regressions (SVRs) to predict the levels of 10-year yields, 3-month yields, 2s10s, DXY index, VIX, high-yield (HY) and investment-grade (IG) spreads. We then define measures of monetary policy (``FDIF'' variables)
