This paper introduces a sparse and stable optimization approach for a multi-currency asset allocation problem. We study the benefits of joint optimization of assets and currencies as opposed to the standard industry practice of managing currency risk via so-called currency overlay strategies. In...

Using a novel and comprehensive dataset, we provide the first systematic study of liquidity in the foreign exchange (FX) market. Contrary to common perceptions, we find significant variation in liquidity across exchange rates, substantial costs due to FX illiquidity, and strong commonality in...

The failure of uncovered interest rate parity to explain short-term interest rate movements is well documented. We show that short-term changes in long-term interest rates do help to explain short-term exchange rate movements. The relationship gets stronger over our sample period, as the...

We develop a general equilibrium model with intermediaries at the heart of international financial markets. Global intermediaries bargain with households and extract rents for providing access to foreign claims. The behavior of intermediaries, by tilting state prices, breaks monetary neutrality...

We re-examine the relationship between exchange rate movements and firm value. We estimate the exchange rate exposure of publicly listed U.S. firms clustered into eleven industries. Using a panel approach, we uncover statistically significant and sizable unconditional exposure. We also examine...

I study crash risk in currency markets by means of a proxy for global skewness, which measures the aggregate asymmetry of daily changes in spot exchange rates involved in a carry-trade portfolio. I find that this factor is priced in the cross-section of individual currencies. The premium for...

Market integration and currency risk are two main factors that distinguish international investment and financing decisions. Hence, we investigate the impact of currency factor on the dynamics of market integration. We compare integration indices estimated from conditional international asset...

DeMiguel, Garlappi, and Uppal (Review of Financial Studies, 22 (2009), 1915-1953) showed that in the stock market, it is difficult for an optimized portfolio constructed using mean-variance analysis to outperform a simple equally-weighted portfolio because of estimation error. In this paper, we...
