This paper investigates the effect of short-sale constraints on price efficiency. We use a unique global dataset on equity lending, collected from several custodians, from January 2004 to June 2006. This information is available weekly for 17,015 stocks from 26 countries. Our main findings are...

This paper uses the cross-sectional variance of the betas to study herd behavior towards the market index in major developed and emerging financial markets (categorized as Developed group, Asian group, and Latin American group). We propose a robust regression technique to calculate the betas of...

This paper focuses on the impact that dispersion of opinions and asymmetric information have on turnover near releases of public information, using the probability of information-based trading (PIN) to proxy for information asymmetry and analysts' forecast dispersion for differences of opinion....

We propose a theory that jointly accounts for an asset illiquidity and for the asset price potential over-reliance on public information. We argue that, when trading frequencies differ across traders, asset prices reflect investors' Higher Order Expectations (HOEs) about the two factors that...

We investigate the dynamic of prices, information and expectations in a competitive, noisy, dynamic asset pricing equilibrium model. We look at the bias of prices as estimators of fundamental value in relation to traders' average expectations and note that prices are more (less) biased than...

This paper looks at the determinants of country and industry specific factors in international portfolio returns using a sample of thirty-six countries and thirty-nine industries over the last three decades. Country factors have remained relatively stable over the sample period, while industry...

In this paper we test the profitability of momentum strategies in the United Kingdom, Germany, Japan and China over the period 1991 to 2006 and sub-periods. Both RSS (Relative Strength Strategies) and WRSS (Weighted Relative Strength Strategies) are used to form the momentum portfolios. We find...

This paper uses currency option data from the BMF, the Commodities and Futures exchange in Sao Paulo, Brazil, to investigate market expectations on the Brazilian Real-U.S. dollar exchange rate from October 1994 through March 1999. Using options data, we derive implied probability density...

This paper looks at the responsiveness of a country's export supply to exchange rate changes and measures its quantitative importance by breaking down export adjustments between changes in output levels by existing exporters (intensive margin) and movements due to changes in the number of...

A model is presented of a uniform price auction where bidders compete in demand schedules; the model allows for common and private values in the absence of exogenous noise. It is shown how private information yields more market power than the levels seen with full information. Results obtained...
