This paper develops a simple but general methodology to estimate the expected intertemporal marginal rate of substitution or quot;EMRSquot;, using only data on asset prices and returns. Our empirical strategy is general, and allows the EMRS to vary arbitrarily over time. A novel feature of our...

Most of the literature on two-tier exchange markets is built around models in which domestic policy can exert a powerful influence on the spread between the current account exchange rate and the capital account exchange rate. We show that if optimizing agents are risk neutral, domestic policy...

Observers have often characterized asset markets as being subject to periods of tranquility and periods of turbulence. Until recently, however, researchers were unable to produce closed-form asset pricing formulas in a model environment of time-varying risk. Some work by Abel provided us with...

This paper develops a simple new methodology to test for asset integration and applies it within and between American stock markets. Our technique is tightly based on a general intertemporal asset-pricing model, and relies on estimating and comparing expected risk-free rates across assets....

Evidence of excess volatilities of asset prices compared with those of market fundamentals is often attributed to speculative bubbles. This study examines the sense in which speculative bubbles could in theory lead to excess volatility, hut it demonstrates that some of the variance hounds...

In this paper we generalize the target zone exchange rate as model formalized by Krugman (1988b) to include finite-sized interventions in defense of the zone. The main contributions of these pages consist of linking the recent developments in the theory of target zones to the mirror-image theory...

In the context of a flexible-price monetary exchange rate model and the assumption of uncovered interest parity, we obtain a measure of the fundamental determinant of exchange rates. Daily data for the European Monetary System are used to explore the importance of non-linearities in the...

Several recent studies have attributed a large part of asset price volatility to self-fulfilling expectations. Such an explanation is unattractive to many since it allows allocations that need bear no particular relation to those implied by the economist's standard kit ofmarket fundamentals. We...

In this paper we present a model in which a systematic banking collapse is possible in a perfect foresight, general equilibrium context. Our aim is to determine con3itions under which a collapse will eventually occur and the timing of such a collapse. The collapse can occur endogenously, driven...

The paper considers the merits of rules and discretion for monetary policy when the structure of the macroeconomic model and the probability distributions of disturbances are not well defined. It is argued that when it is costly to delay policy reactions to seldom-experienced shocks until formal...
