Market Making in the Options Markets and the Costs of Discrete Hedge Rebalancing

In this paper we provide empirical evidence consistent with the hypothesis that options market makers face risks in managing inventory that are unique to the options markets. In particular, we show that risks associated with the inability to rebalance an option position continuously and uncertainty about the return volatility of the underlying stock each account for a statistically and economically significant proportion of the bid-ask spreads quoted for a sample of Chicago Board Options Exchange options.     

THE GREAT DEPRESSION RECONSIDERED: IMPLICATIONS FOR TODAY

This paper reexamines the Great Depression of 1929–1933 within an analytical framework based on the terms of employment for labor. It shows that in areas such as the U.S. farm and Japanese industrial sectors where labor was employed organically—that is, as partners in common enterprise—costs proved flexible, prices fell, and output and employment held up in line with the predictions of Say's Law. Where labor was not employed organically—that is, labor was hired—output collapsed, unemployment mounted, and Say's Law failed. The apparent reason is that any hired input, capital or labor, demands downwardly rigid rates of pay. When demand softens, cost rigidity constrains price cuts, and firms must instead lay off labor. The paper also shows that given organic labor, even oligopolistic rivalry is sufficient to assure that prices will fall enough to sustain output and employment.     

Users versus nonusers of supplements: socioeconomic characteristics

The objective of this research was to determine the socioeconomic characteristics of supplement users versus nonusers. Seven western states (Arizona, California, Idaho, Nevada, New Mexico, Oregon and Wyoming) were surveyed to determine the socioeconomic profile of persons who either use or do not use supplements. Results indicated that 60.2% of the supplement users were female. The largest percentage was 31–40 years of age. By most definitions, supplement users tended to be well educated. Under adverse economic conditions, only a small percentage (7%) of users would give up supplements first when asked to choose from a variety of items that were considered to be nonessential.     

Labor Market Discrimination against Women with Disabilities

This article estimates the extent of wage discrimination and, for the first time, the employment effects of wage discrimination, against women with disabilities. In 1984, more than one-half of the offer wage differential between disabled and nondisabled women is attributable to discrimination, but the absolute wage differential is small. The results suggest that wage discrimination related to disability tends to be most severe for a relatively small group of women with impairments against which prejudice is most intense. There is a large difference between the employment rates of disabled and nondisabled women but only a small part of the differential is attributable to the disincentive effects of wage discrimination. The results also show that women with disabilities face a double burden of gender- and disability-related discrimination, but do not show that gender-related discrimination is worse for women who have a disability.     

SMALL ENTERPRISE DEVELOPMENT AND THE EMPLOYMENT-OUTPUT TRADE-OFF

THIS paper analyzes the potential of small-scale enterprisedevelopment for absorbing labor while maintaining output growthin developing countries. Addition of a small-scale, intermediatesector to the modern-informal framework of a Harris-Todaro typemodel demonstrates that negative migration and unemploymentresponses to urban job creation can be avoided. The multi-sectormodel shows that observed characteristics of large and smallfirms are explainable by capital market segmentation, and themodel is used to analyze the effects of changes in policy variables.Expansion of demand for small-scale products is a particularlypromising approach. Conditions for an employment-output trade-offto arise are analyzed to show the need for balance between smalland large scale sector expansion.     

The Choice of Private Versus Public Capital Markets: Evidence from Privatizations

We examine the impact of political, institutional, and economic factors on the choice between selling a state‐owned enterprise in the public capital market through a share issue privatization (SIP) and selling it in the private capital market in an asset sale. SIPs are more likely in less developed capital markets, for more profitable state‐owned enterprises, and where there are more protections of minority shareholders. Asset sales are more likely when there is less state control of the economy and when the firm is smaller. Our results suggest the importance of privatization activities in developing the equity markets of privatizing countries.
