Traditionally and understandably, the microscope of market microstructure has focused on attributes of single assets. Little theoretical attention and virtually no empirical work has been devoted to common determinants of liquidity nor to their empirical manifestation, correlated movements in...

This paper examines the mechanism by which the incorporation of information into prices leads to cross-autocorrelations in stock returns. We present a simple model where trading on private information occurs first in the large stocks and is transmitted to small stocks with a lag. Such trading...

In this paper, we analyze cross-sectional heterogeneity in the time-series variation of liquidity. Average daily changes in liquidity exhibit significant heterogeneity in the cross-section; the liquidity of small firms varies more on a daily basis than that of large firms. A steady increase in...

We explore the sharp uptrend in trading activity during recent years. Higher turnover has been associated with more frequent smaller trades, which have progressively formed a larger fraction of trading volume over time. Evidence indicates that secular decreases in trading costs have influenced...

We analyze the relation between equity returns, risk, and a rich set of security characteristics that includes institutional ownership, Samp;P 500 index membership, analyst following, and dispersion in analyst forecasts, in addition to previously examined variables such as the book-to-market...

This article analyzes the effects of a finite tick size and the practice of quot;payment-for-order flowquot; on market maker competition. Even if the NYSE reservation price is superior to its non-NYSE counterpart, brokers may, due to payment-for-order flow, prefer to execute orders off the NYSE...

We examine whether the recent regime of increased liquidity and trading activity is associated with attenuation of prominent equity return anomalies due to increased arbitrage. We find that the majority of the anomalies have attenuated and the average returns from a portfolio strategy based on...

In this paper, we analyse cross-sectional heterogeneity in the time-series variation of liquidity in equity markets. Our analysis uses a broad time-series and cross-section of liquidity data. We find that average daily changes in liquidity exhibit significant heterogeneity in the cross-section;...
