The purpose of this paper is to investigate the tests of Hansen (1991) to detect structural breaks in cointegrated relations using Monte Carlo methods. The evaluation takes place within the linear quadratic model. The evidence for a single regressor suggests that the test have proper size and...

We examine the behavior of forward and spot exchange rates from the perspective of the representative agent theory of asset pricing. We verify that with moderate risk aversion and time-additive preferences the theory accounts for very little (by our calculations, less than 5 percent) of the...

A test of a dynamic, macroeconomic model with free parameters is provided by comparing its features, such as moments, with those of historical data. We provide a method for studying the distribution of the sample moment under the null hypothesis that the model is true. We calculate the size of...

We review the recent research on time-varying risk premiums, including attempts to explain rejection by Baillie and others of "the unbiasedness hypothesis." Using spot and forward foreign exchange rates we discuss the evidence for time-varying risk premiums, relate it to general equilibrium...

Capitation models have been suggested as an alternative to funding methods baseed on historical utilization patterns. Capitation funding distributes resources to regions or programs according to their population, adjusted for the age and gender composition and relative need. The most commonly...

Using an extensive survey of Canadian physicians, the authors study how physician practice patterns are shaped by demographic characteristics, physician specialty, and government policy. They model the simultaneous determination of group size, primary source of professional income...

This article examines the value of lead information by investigating the predictive power the automatic data processing (ADP) report has on nonfarm payroll employment data released by the Bureau of Labor Statistics (BLS) 2 days after the ADP. We find that updating a vector autoregression (VAR)...
