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 right offerings around the world, using a sample of 8,238 rights offers announced during 1995-2008 in 69 countries. Although shareholders prefer having the option to trade rights, issuers deliberately restrict tradability in 38% of the offerings. We argue that firms restrict rights...

Traditional portfolio balance theory derives a downward sloping currency demand function from limited international asset substitutability. Historically, this theory enjoyed little empirical support. We provide direct evidence by examining the exchange rate effect of a major redefinition of the...

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...

We study the link between social interaction and stock market bubbles. We argue that an increase in social interaction may facilitate the birth of a cascade-type pattern and indirectly of a bubble. We concentrate on a form of interaction that is rooted back in the past: college-based interaction...
