The asymptotic distributions of the maximum likelihood estimator of the persistence parameter are developed in a linear diffusion model under three sampling schemes, long-span, in-fill and double. Simulations suggest that the in-fill asymptotic distribution gives a more accurate approximation to...

This paper shows that when Value-at-Risk constrained institutional investors care about their relative standings among the peer group, more risk averse investors would take more risk, which improves the risk sharing and lowers the volatility.

We investigate whether the use of component forecasts improves the accuracy of a portfolio forecast which uses only aggregate data. The results show that the use of component data improves the accuracy of aggregate forecasts. Furthermore, the long–short trading strategy based on the component...

We use extreme value theory to analyse the tails of a momentum strategy’s return distribution. The asymmetry between the fat left tail and thin right tail strongly reduces a momentum strategy’s prospective utility levels.

Estimates of agents’ risk aversion differ between market studies and experimental studies. We demonstrate that these estimates can be reconciled through consistent treatment of agents’ propensity for narrow framing.

This paper proposes a new dividend-based S&P 500 Index return predictor, the implied dividend yield term structure (IDYTS). We show that the IDYTS is a “cleaner” predictor than its conventional counterpart, the dividend price ratio (DP), in that the expected return is a linear combination...

In this study, we determine the reliability and exogeneity of four popular monetary policy shock measures, namely the narrative series of Romer and Romer (2004), the high-frequency series of Barakchian and Crowe (2013), the high-frequency series of Gertler and Karadi (2015), and the hybrid...

We derive a neat and compact representation of the asymptotic Fisher information matrix of a vector ARMA process. Its inverse can be used immediately as the asymptotic covariance matrix of the Gaussian maximum likelihood estimator. We also provide the robust sandwich covariance estimator when...

We propose an empirical likelihood-based method of inference for comparing inequality between two populations. A series of Monte Carlo experiments are used to assess our method’s finite sample performance. We illustrate our approach using some Canadian household income data.

In this paper we provide a general solution to the problem of controlling the probability of a type I error in normality tests for the disturbances in linear regressions when using robust-regression residuals. We show that many classes of well-known robust regression estimators belong to the...
