Researchers often employ ARCH models to estimate conditional variances and covariances. How successfully can misspecified ARCH models carry out this estimation? This paper employs continuous record asymptotics to approximate the distribution of the measurement error. This allows the authors to...

This paper examines theoretical properties of incentive contracts in the hedge fund industry. We show that it is very difficult to structure incentive payments that distinguish between unskilled managers, who cannot generate excess market returns, and skilled managers who can deliver such...

It is widely known that conditional covariances of asset returns change over time. Researchers doing empirical work have adopted many strategies for accommodating conditional heteroskedasticity. One popular strategy is performing rolling regressions in which only data from, say, the preceding...
