We show that both the quoted and effective spreads increased, the quoted depth decreased, and the market quality index decreased after the implementation of Regulation NMS (Reg NMS). We also find an increase in the price impact of trades and the dispersion of the pricing error after Reg NMS. The...

We analyze the equilibrium spread when the transaction size of informed traders is elastic in the value of private information (α). We show that the pooling equilibrium is likely to be inefficient when trade size is sensitive to α and the inefficient equilibrium can occur before the market...

We analyze the effects of monetary policy announcements on stock market liquidity using intraday data. We show that the impairment in liquidity associated with policy announcements occurs primarily after, rather than before, the announcements, and is relatively short-lived, lasting about 1.5...

In this study we examine the relation between corporate governance and institutional ownership. Our empirical results show that the fraction of a company's shares that are held by institutional investors increases with the quality of its governance structure. In a similar vein, we show that the...

In this study we analyze the effect of the security analysis activities on stock market liquidity and execution quality. We show that stocks followed by financial analysts have better market liquidity and execution quality than stocks with no analyst following, and stocks followed by affiliated...

This paper examines whether commercial success in the popular recorded-music industry, as measured by gold-record output, conforms to an empirical concentration. We find that Lotka's Law overestimates the number of artists with one gold record and underestimates the number of...

This paper analyzes the relation between institutional investment duration and corporate governance using a new metric of investment duration that accounts for firm-specific investment durations of each institution. We conjecture that institutional investors that hold a firm's shares for a...

We show that both the number of institutional investors and the percentage of shares that are held by institutional investors increase significantly after reverse splits with a pre-split price lower than $5 and a target price higher than $5. This effect is larger than for other comparable...

We explore the relation between corporate governance and the informational efficiency of prices (IEP). We find that IEP increases with the quality of corporate governance in a large cross-section of firms. We show that firms with better governance structures file Form 8-K reports more promptly...

In this study we analyze the effect of information asymmetry on corporate cash holdings. Using various measures of information asymmetry, we show that companies that operate in higher information asymmetry environments have smaller cash holdings. We continue to find a negative relation between...
