Decline in confidence in free market mechanisms in the past decade has provoked an increase in interest in regulatory issues. This paper seeks to answer one question: Are exchange listing rules an effective screening mechanism? Using a sample of IPO firms listing on major U.S. exchanges in...

In 2002, the Financial Accounting Standards Board allowed corporations to recognize stock options as an expense on their financial statements on a voluntary basis. Option expensing became mandatory in 2004. This investigation uses two different models to reexamine the effects of the announcement...

The simple happenstance of the overall stock market being up or down for the day can explain a substantial portion of the abnormal return attached to corporate news announcements. In particular, we demonstrate that firm-specific news announcements that are typically met with a positive stock...

Quarterly earnings conference calls are becoming a more pervasive tool for corporate disclosure. However, the extent to which the market embeds information contained in the tone (i.e. sentiment) of conference call wording is unknown. Using computer aided content analysis, we examine the...

This study examines empirically the role of financial information in explaining long return windows in three major capital markets, UK, USA and France. We hypothesize that the relationship between financial information and security returns improves the longer the return window, and that this...

We propose a theory of asset prices that emphasizes heterogeneous information as the main element determining prices of different securities. Our main analytical innovation is in formulating a model of noisy information aggregation through asset prices, which is parsimonious and tractable, yet...

We use price pressure resulting from purchases by mutual funds with large capital inflows to identify overvalued equity. This is a relatively exogenous overvaluation indicator as it is associated with who is buying, buyers with excess liquidity, rather than what is being purchased. We document...
