Separate literatures study violations of uncovered interest parity (UIP) using regression-based and portfolio-based methods. We propose a decomposition of these violations into a cross-currency, a between-time-and-currency, and a cross-time component that allows us to analytically relate...

We present theory and evidence that challenges the view that forward premia contain little information regarding subsequent spot rate movements. Using weekly dollar-mark and dollar sterling data, we find that spot and forward exchange rates together are well represented by a vector error...

I explore the behavior of asset prices and the exchange rate in a two-country world. When the large country has bad news, the relative price of the small country's output declines. As a result, the small country's bonds are risky, and uncovered interest parity fails, with positive excess returns...

This paper develops an explicitly stochastic new open economy macroeconomics' model, which can potentially be used to explore the qualitative and quantitative welfare differences between alternative exchange rate regimes. A crucial feature is that we do not simplify by assuming certainty...

This paper reexamines the widely-held wisdom that the currency exposure of international investments should be entirely hedged. It finds that the previously documented ability of hedges to reduce portfolio return variance holds at short horizons, but not at long horizons. At horizons of several...

We describe a novel currency investment strategy, the 'dollar carry trade,' which delivers large excess returns, uncorrelated with the returns on well-known carry trade strategies. Using a no-arbitrage model of exchange rates we show that these excess returns compensate U.S. investors for taking...

Aggregate consumption growth risk explains why low interest rate currencies do not appreciate as much as the interest rate differential and why high interest rate currencies do not depreciate as much as the interest rate differential. We sort foreign T-bills into portfolios based on the nominal...

Survey data on a broad cross section of 17 currencies are used to determine whether the forward discount moves primarily in response to changes in expectations of depreciation, or in the risk premium. We find that changes in expected depreciation are quantitatively significant. However we also...
