Efficiency of Non-Walrasian Equilibria

Econometrica 1980 48(1), 127
[In this paper, Pareto efficiency properties of a non-Walrasian equilibrium for an exchange economy are analyzed. The equilibrium considered is a generalized version of Drèze's equilibrium with price rigidities and rationing.]

Discretely adjusted option hedges

Journal of Financial Economics 1980 8(3), 259-282
This paper analyses the distribution of returns on a hedged portfolio, consisting of a European call option and its associated stock, when the portfolio is rebalanced at discrete time intervals. Under the assumptions of the Black-Scholes model this distribution is particularly skew. In tests of the average return on a hedged portfolio this skewness leads to biased t-statistics. The paper explores the nature and extent of this bias and suggests procedures for overcoming it. Other aspects of discrete hedging are also discussed.

Additional Evidence of Heteroscedasticity in the Market Model

Journal of Financial and Quantitative Analysis 1980 15(2), 299
Sharpe's market model [29] is widely used both by academic researchers and practitioners in finance, but it cannot be accepted with complete confidence until some of its basic assumptions are tested more thoroughly. The applicability, usefulness, and reliability of the model are functions of its conformity to real data, which in turn depends partly on the unresolved question of heteroscedasticity.

The Price Effects of Rights Offerings

Journal of Financial and Quantitative Analysis 1980 15(1), 25
In the theoretical literature of finance, it has been assumed for some time that capital markets are efficient, with security prices reflecting all available information [10]. One purpose of this paper is to consider market efficiency in the context of rights offerings. It has recently been suggested, for example, that rights offerings afford positive abnormal returns [17, 18]. This view was immediately countered by the comment that the number of rights issued, and inversely the issue price, cannot affect the market value of the total exrights equity market [21, p. 44]. No empirical evidence was offered on either side, however.
