This paper examines how the difference in institutional environment across various provinces in China can explain IPO underpricing in the Chinese equity market. Using Chinese IPO data from 1999 to 2007, we find strong evidence that firms located in regions with better institutional environment...

We examine two inconclusive issues in the IPO underpricing literature. It is unclear if private firms or government-owned firms (SOEs) underprice their IPOs more and how institutional environment affects IPO underpricing. Using a much larger China IPO sample of SOEs, we conclude that SOEs...

We propose a new model for dynamic volatilities and correlations of skewed and heavy-tailed data. Our model endows the Generalized Hyperbolic distribution with time-varying parameters driven by the score of the observation density function. The key novelty in our approach is the fact that the...

This paper develops a method to improve the estimation of jump variation using high frequency data with the existence of market microstructure noises. Accurate estimation of jump variation is in high demand, as it is an important component of volatility in finance for portfolio allocation,...

The motivation and characteristics of firms that announce stock repurchase programs but do not carry them out are poorly understood. We conjecture that the long-term earnings quality of such firms is low, which makes them poor candidates for subsequent stock purchase. Their announcement is just...

The standard test for the pricing role of aggregate idiosyncratic risk in the conventional predictive regression considers aggregate total idiosyncratic risk a reasonable proxy for its undiversified component, which should be priced as theory suggests. However, when the priced component is...
