We apply the method of constrained asset share estimation (CASE) to test the mean-variance efficiency (MVE) of the stock market. This method allows conditional expected returns to vary in relatively unrestricted ways. The data estimate reasonably the price of risk, and, in some cases, the MVE...

Implications of factor-based asset pricing models for estimation of expected returns and for portfolio selection are investigated. In the presence of model mispricing due to a missing risk factor, the mispricing and the residual covariance matrix are linked together. Imposing a strong form of...

This study quantitatively investigates the currency composition of sovereign debt in the presence of two types of limited enforcement frictions arising from a government's monetary and debt policy: strategic currency debasement and default on sovereign debt. Local currency debt obligations are...

We re-examine the time-series evidence for failures of uncovered interest rate parity on short-term deposits for the U.S. dollar versus major currencies of developed countries at short-, medium- and long-horizons. The evidence that interest rate differentials predict foreign exchange risk...

We investigate the portfolio choices of mean-variance-optimizing investors who use sample evidence to update prior beliefs centered on either risk-based or characteristic-based pricing models. With dogmatic beliefs in such models and an unconstrained ratio of position size to capital, optimal...

The management of the exchange rate is possible only if the government pursues a monetary-fiscal policy mix which is consistent with its exchange rate targets. In this paper with uncertainty concerning the length of individual life the real consequences of exchange rate management depend on the...

The collapse of a fixed exchange rate is typically marked by a sudden balance-of-payments crisis in which"speculators" fleeing from the domestic currency acquire a large portion of the central bank's foreign exchange holdings.Faced with such an attack, the central bank often withdraws...

The paper develops a model of exchange-rate and current-account determination for a small economy peopled by infinitely lived, utility-maximizing households. In this setting, a central-bank purchase of foreign exchange has no real effects when central-bank foreign reserves earn interest at the...

This paper investigates the long- and short-run neutrality of open-market monetary policy in a world of fixed exchange rates and imperfect substitutability between bonds denominated in different currencies. Using an illustrative portfolio-balance model, it shows that when the public discounts...

We argue that active management's popularity is not puzzling despite the industry's poor track record. Our explanation features decreasing returns to scale: As the industry's size increases, every manager's ability to outperform passive benchmarks declines. The poor track record occurred before...
