We study how dealers behave when there exist parallel markets for the same asset that are characterized by very different degrees of transparency. We show that the optimal trading strategy, depending on the features of the less transparent market and on the informational uncertainty in the more...

We study how dealers behave when there exist parallel markets for the same asset that are characterized by very different degrees of transparency. We show that the optimal trading strategy, depending on the features of the less transparent market, may involve price manipulation. Informed dealers...

We exploit the merger between BlackRock and Barclays Global Investors to study how changes in expected ownership concentration affect the investment behavior of funds and the cross-section of stocks worldwide. We find that funds with open-end structures and a large exposure to commonly-held...

We study the link between informed trading and co-movement in illiquidity. We argue that investors concerned with liquidity and fire-sale shocks respond to an increase in informed trading by shifting their portfolios away from stocks with high information asymmetry. This rebalancing causes a...

We study how product market competition affects the firm's ownership by international and domestic investors and its stock performance. We argue that in the presence of local bias domestic investors tilt their portfolios towards domestic stocks that offer lower exposure to country-specific...

We highlight an important but overlooked characteristic of financial fragility: “fragile” stocks are more liquid because they are sensitive to non-fundamental liquidity shocks. This reduces their sensitivity to corporate actions with price impact and affects the firms’ incentives to engage...

We investigate how short sellers strategically exploit the liquidity generated by the arrival of ambiguous information – i.e. information likely to cause disagreement in interpretation. Using a sample of newspaper articles, media newswires, and press releases, we construct a measure of...

We investigate whether short sellers are subject to the disposition effect using a novel dataset that allows to identify the weekly closing of short positions. Consistent with the disposition effect, the closing of short sale positions is strongly related to a proxy of Shortsale Capital Gains...

We study IPOs by focusing on the degree of portfolio diversification of the shareholders taking the company public. We argue that a less diversified shareholder has more to gain from taking the company public and would be more willing to accept a lower price for the sale of its shares, i.e....

Using a large sample of US active equity mutual funds from 1983 to 2001, we show that portfolio liquidity is actively managed and chosen as a function of the multiple liquidity needs a fund has. Using portfolio liquidity as a parsimonious proxy for the severity of liquidity needs, we find that...
