Using the Kalman filter, we obtain maximum likelihood estimates of a permanent-transitory components model for log spot and forward dollar prices of the pound, the franc, and the yen. This simple parametric model is useful in understanding why the forward rate may be an unbiased predictor of the...

The Euler equations derived from intertemporal asset pricing models, together with the unconditional moments of asset returns, imply a lower bound on the volatility of the intertemporal marginal rate of substitution. This paper develops and implements statistical tests of these lower bound...

This paper draws on Robert F. Engle's autoregressive conditionally heteroskedastic modeling strategy to formulate a conditional capital asset pricing model with time-varying risk and expected returns. The model is estimated by generalized method of moments. A capital asset pricing model that...

This paper introduces tests for residual serial correlation in cointegrating regressions. The tests are devised in the frequency domain by using the spectral measure estimates. The asymptotic distributions of the tests are derived and test consistency is established. The asymptotic distributions...

This paper employs quarterly observations on US dollar prices of the pound, Deutschmark, Swiss franc, and yen from 1973,2 to 1994,4 to sort out three broad issues raised by recent work showing that economic fundamentals have predictive power for exchange rates at long horizons. Three alternative...

The authors develop and test a monetary rational expectations model of the Swiss/U.S. exchange rate. Two salient features of the model are the assumption that domestic and foreign currency denominated assets are imperfect substitues, and that purchasing power parity need not hold. The authors...

The authors present a stochastic model of two barter economies, with production, linked by free trade in goods and securities, which generates Pareto-efficient international transmissions of business cycle disturbances. Each country is inhabi ted by an infinitely-lived, representative firm and...
