This project applies the methods of functional data analysis (FDA) to intra-daily returns of US corporations. It focuses on an extension of the Capital Asset Pricing Model (CAPM) to such returns. The CAPM is essentially a linear regression with the slope coefficient . Returns of an asset are...

An increase in the cost of short selling should increase the bearish information content of short interest announcements by driving relatively uninformed short sellers out of the market (Diamond and Verrecchia, 1987). We extend the Diamond and Verrecchia model to include short selling against...

A field study conducted in Shanghai identified a robust inconsistency between real estate developers' desired sales pattern (selling all apartments in a building at similar rates) and the actual sales pattern (selling good apartments faster). The authors explained this inconsistency with...

We study auditors' client risk management in the first year of SOX 404 implementation, and find that there exists a pecking order among auditors' strategies to manage control risk resulting from internal control weaknesses. We first examine the relations between internal control weaknesses and...

This paper examines the effect of the inherent demand implied by short interest by observing price reactions to earnings announcements based on the level of short interest. We find that for extreme good- and bad- news events, the inherent demand increases stock prices around the earnings...

This paper examines the potential impacts of artificial smoothing (abnormal accruals) and real smoothing (derivatives) on firm value. We find that the value of the firm decreases with the magnitude of abnormal accruals and increases with the level of derivative use. Moreover, the accrual...

This paper examines how product market competition is related to the impacts of cross-listing events for both the listing firms and their domestic non-cross-listed rivals. I find that issuing firms enjoy higher abnormal returns and greater subsequent market-share increases when they share more...
