This paper studies multiscale stochastic volatility models of financial asset returns. It specifies two components in the log-volatility process and allows for leverage/asymmetric effects from both components while return innovation terms follow a heavy/fat tailed Student t distribution. The two...

We examine the theoretical, empirical, and public policy implications of the proportion of females in the establishment. Arrow's model of heterogeneous employer discrimination provides predictions that are tested. Empirical results indicate support for the theory using establishment data, but a...

This paper compares two well-known approaches for valuing a risky investment using real options theory:contingent claims (CC) with risk neutral valuation and dynamic programming (DP) using a constant risk adjusted discount rate.Both approaches have been used in valuing forest assets.A proof is...

This article considers risk measures constructed under a discrete mixture-of-normal distribution on the innovations of a GARCH model with time-varying volatility. The authors use an approach based on a continuous empirical characteristic function to estimate the parameters of the model using...

A copula approach is used to examine the extreme return-volume relationship in six emerging East-Asian equity markets. The empirical results indicate that there is significant and asymmetric return-volume dependence at extremes for these markets. In particular, extremely high returns (large...

This paper proposes a new time-deformation model for stock returns sampled in transaction time and directed by a generalized duration process. Stochastic volatility in this model is driven by an observed duration process and a latent autoregressive process. Parameter estimation in the model is...

This paper tests the prediction of the Permanent Income Hypothesis (PIH) that news about future income induce a revision in consumption equal to the revision in permanent income. We use time-series data from 48 contiguous US states to perform the test. The empirical results provide some support...

This paper investigates whether there are variants of the permanent income model that are consistent with seasonally unadjusted quarterly postwar Canadian data. The analysis is based on a misspecification-test equation which nests the standard permanent income model. The results obtaineda re...
