Market risk management traditionally has focussed on the distribution of portfolio value changes resulting from moves in the midpoint of bid and ask prices. Hence the market risk is really in a “pure” form: risk in an idealized market with no “friction” in obtaining the fair price....

This paper investigates the empirical characteristics of investor risk aversion over equity return states by estimating a daily semi-parametric pricing kernel. The two key features of this estimator are: (1) the functional form of the pricing kernel is estimated semi-parametrically, instead of...

This paper examines the relationship between consumption-based and option-based risk-neutral moments, providing a technique to explore consumption-based pricing kernel specifications using data from the options markets. Estimators for average risk-neutral moments of each type are proposed and...

After an initial public offering, most existing shareholders are subject to a lock-up period in which they cannot sell their shares for a prespecifed time. At the end of the lock-up, there is a permanent and large shift in the supply of shares. The lock-up expiration is a particularly...

This paper surveys the empirical and theoretical literature on the mechanisms of corporate governance. We focus on the internat mechanisms of corporate governance (e.g., arising from conflicts of interests between managers and equityholders, equityholders and creditors, and capital contributors...

How important are cross-stock common factors in the price discovery/liquidity provision process in equity markets? We investigate two aspects of this question for the thirty Dow stocks. First, using principal components and canonical correlation analyses we find that both returns and order flows...

In this paper we review Cowles' evidence and find that it supports the contrary conclusion - that the Dow Theory, as applied by...

This paper reassesses the role of economic fundamentals in the 1987 stock market crash using a two factor common-component model of returns. The model decomposes returns into idiosyncratic components, a common white noise component, and a common source of Poisson jumps. Among three two-year...
