Financial returns typically display heavy tails and some skewness, and conditional variance models with these features often outperform more limited models. The difference in performance may be especially important in estimating quantities that depend on tail features, including risk measures...

We study, both empirically and quantitatively, the role of savings and the labor supply in self-insurance channels over the life cycle when one faces not only idiosyncratic income risks, but also changes in longevity risk and pension benefits. We pick China as a case study since China has...

The Chinese stock market has witnessed a dramatic increase of analyst coverage over the past years. While analyst revisions clearly exhibit optimistic biases, we find significant market reactions to both upgrades and downgrades. However, in contrast to findings in existing literature for other...

We decompose daily (close-to-close) changes of VIX into overnight (close-to-open) and trading-hour (open-to-close) changes. Consistent with the notion that non-trading creates uncertainty and trading resolves uncertainty, we find that there is generally an increase in VIX overnight and decrease...

This paper describes a general procedure for constructing a class of asymmetric distributions based on symmetric parametric distribution families, and investigates some inherent relationships between the constructed asymmetric distribution and the original symmetric ones. This procedure is used...

This paper proposes a new class of asymmetric Student-t (AST) distributions, and investigates its properties, gives procedures for estimation, and indicates applications in financial econometrics. We derive analytical expressions for the cdf, quantile function, moments, and quantities useful in...

The new distribution class, Asymmetric Exponential Power Distribution (AEPD), proposed in this paper generalizes the class of Skewed Exponential Power Distributions (SEPD) in a way that in addition to skewness introduces different decay rates of density in the left and right tails. Our...
