Theoretical asset pricing models routinely assume that investors have heterogeneous information. We provide direct evidence of the importance of information asymmetry for asset prices and investor demands using plausibly exogenous variation in the supply of information caused by the closure or...

We examine the pricing of financial crash insurance during the 2007-2009 financial crisis in U.S. option markets. A large amount of aggregate tail risk is missing from the price of financial sector crash insurance during the financial crisis. The difference in costs of out-of-the-money put...

We empirically analyze the pricing of political uncertainty, guided by a theoretical model of government policy choice. After deriving the model's predictions for option prices, we test those predictions in an international sample of national elections and global summits. We find that political...

What role do sentiment investors play in the pricing of newly listed stocks? We derive conditions under which we can distinguish between sentiment and rational pricing behaviour and test for the rationality of small investors’ demand for new stock issues using data from pre-issue (or...

IPO initial returns reached astronomical levels during 1999-2000. We show that the regime shift in initial returns and other elements of pricing behaviour can be at least partially accounted for by a variety of marked changes in pre-IPO ownership structure and insider selling behaviour over the...

Our model of the initial public offering process links the three main empirical IPO ‘anomalies’ – underpricing, hot issue markets, and long-run underperformance – and traces them to a common source of inefficiency. We relate hot IPO markets (such as the 1999/2000 market for Internet...

We study the efficiency of internal capital markets at state-controlled and privately owned business groups in China. Using highly granular data on within-group capital flows, we document stark differences: while private groups allocate more capital to units with better investment opportunities,...

Is greater trading liquidity good or bad for corporate governance? We address this question both theoretically and empirically. We solve a model consisting of an optimal IPO followed by a dynamic Kyle market in which the large investor's private information concerns her own plans for taking an...

Financial constraints are fundamental to empirical research in finance and economics. We propose two novel tests to evaluate how well measures of financial constraints actually capture constraints. We find that firms classified as constrained according to five popular measures do not in fact...

We investigate directly whether analyst behaviour influenced the likelihood of banks winning underwriting mandates for a sample of 16,625 US debt and equity offerings sold between December 1993 and June 2002. We control for the strength of the issuer’s investment-banking relationships with...
