When rates of return on bonds are computed over extremely short holding periods, the ex post cross-sectional relationship between realized return and risk is linear. It is therefore possible, at any time, to extrapolate the cross-sectional relationship to a zero risk level, and thus to determine...

In this article we examine the effect of the imperfect mobility of goods on international risk sharing and, through that, on the investment in risky projects, welfare, and growth. Our main result is that the welfare gain from integration of financial markets is not greatly reduced by the...

When several investors with different risk aversions trade competitively in a capital market, the allocation of wealth fluctuates randomly among them and acts as a state variable against which each market participant will want to hedge. This hedging motive complicates the investors' portfolio...

We develop an international financial market model in which domestic and foreign residents differ in their beliefs about the information content in public signals. We determine how informational advantages by domestic (foreign) investors in the interpretation of home (foreign) public signals...

Under different assumptions about the underlying monetary shocks, we study target zones of various widths and the effect they have on variables like the interest differential. The stochastic disturbances assumed are successively a non-zero mean random walk and a mean reverting process. The...

In this article, our objective is to determine efficient allocations in economies with multiple agents having recursive utility functions. Our main result is to show that in a multiagent economy, the problem of determining efficient allocations can be characterized in terms of a single value...

Transferring physical capital and transferring production and sales activities from one country to the other typically entails large adjustment costs. The model of this paper features two homogeneous stocks of physical capital located in two different countries separated by an ‘ocean.’ The...

The hypothesis being tested in this article is that participants in the foreign exchange market are improperly diversified across currencies. If this type of inefficiency were to be verified, it could constitute an explanation of the large volatility of exchange rates: traders who do not fully...
