Speeding up the exchange does not necessarily improve liquidity. The price quotes of high-frequency market makers are more likely to meet speculative high-frequency "bandits", thus less likely to meet liquidity traders. The bid-ask spread is raised in response. The recursive dynamic model...

This paper exploits hand-collected data on illegal insider trades to provide new evidence of the ability of standard measures of illiquidity to detect informed trading. Controlling for unobserved cross-sectional and time-series variation, sampling bias, and strategic timing of insider trades, I...

If investors are differently informed about the payoff of market-traded securities, then the traditional market portfolio is not a relevant benchmark for testing the CAPM. Each investor appraises expected returns and builds his optimal portfolio conditionally on his information. Which proxy to...

Countercyclical dispersion of firm outcomes (micro dispersion) is commonly used as a proxy for micro uncertainty. In this paper, we characterize conditions under which micro dispersion and micro uncertainty co-move positively in the context of a large Cournot economy with dispersed information...

In this paper we survey the theoretical and empirical literatures on market liquidity. We organize both literatures around three basic questions: (a) how to measure illiquidity, (b) how illiquidity relates to underlying market imperfections and other asset characteristics, and (c) how...

Explaining exchange rates has long been an important but vexing issue in international economics and finance. In recent years, a number of studies have shown that investors' private information plays a central role in determining exchange rates. We demonstrate in this paper that the private...

The Australian Government launched the My School website in 2010 to provide standardised information about the quality of schools to the Australian public. This paper combines data from this website with home sales data for the state of Victoria to estimate the effect of the publication of...

In the Mexican Peso crisis 1994/95, the lack of readily available information, particularly regarding monetary aggregates, has often been commented on. This paper analyzes empirically whether information disparity with respect to economic fundamentals contributed to the crisis. Using historical...

The flow of information between futures and spot prices may vary over time, in particular during periods of stress. This article analyses the information content of the Bund Future and German government bonds during 1998 and test whether it is constant over time. The use of high-frequency data...
