We analyze commonality in informed trading across stocks, and how informed trading varies with the structural and trading characteristics of a firm. We thereby isolate the residual level of informed trading that is unrelated to commonality, trading characteristics, and structural...

I provide a theoretical model for two empirical phenomena observed in the NYSE and Nasdaq markets. First is the bid-ask bounce recently studied by Heston, Korajczuk and Sadka (HKS, 2008) for high-frequency data. Second is a temporary liquidity squeeze observed by Madureira and Underwood (2008)...

We revisit a central task of the extant liquidity literature, which is to identify effective measures of liquidity. We critically assess the influential practice of identifying the best liquidity measures based on monthly correlations by comparing and contrasting correlations between monthly and...

We study the frictions in the patterns of trades in the Euro money market. We characterize the structure of lending relations during the period of recent financial turmoil. We use network-topology method on data from overnight transactions in the Electronic Market for Interbank Deposits (e-Mid)...

This paper offers a dynamic model of the foreign exchange market where some investors in the market are more informed than others. By adjusting the proportion of informed investors in the market, it is shown that the disconnect between macroeconomic variables and the exchange rate is sensitive...

Asset liquidity in modern financial markets is a key but elusive concept. A market is often said to be liquid when the prevailing structure of transactions provides a prompt and secure link between the demand and supply of assets, thus delivering low costs of transaction. Providing a rigorous...

We compute some indicators (zero-trade, turnover ratio, Amihud price impact, and Roll bid-ask spread) to examine the liquidity conditions of corporate bonds traded on the main Italian retail bond markets from January 2010 to June 2013. In order to compare market liquidity for identical...

I address the role of information heterogeneity in the Euro interbank market for unsecured term lending. I use high-frequency quotes of bid and ask prices to estimate probabilities of informed trading for contract maturities from one month to one year. The dataset spans from November 2000 to...
