How Discrimination Against Female Workers Is Hidden in U.S. Industry Statistics: Sex Differences in Wages in the Cotton Textile and Boot and Shoe Industries Between the World Wars

Abstract . The conclusion that the male-female earnings gap largely reflects sex differences in occupational structure is widely accepted, This conventional wisdom is challenged by examining intraoccupational male-female wage differences in two leading manufacturing industries, cotton textiles and boots and shoes, for the 1920s and 1930s. The results show little evidence of sex differences in wage rates in particular occupations in the cotton textile industry. The piece wage system protected the wages of female workers and kept intraoccupational wage differences between the sexes within narrow limits. In contrast, the evidence points to sharp sex differentials in occupational wage rates in the boot and shoe industry. In this industry, piece wages in the different occupations varied directly with the price of the shoes. By assigning work on low quality shoes to females employers were able to practice wage discrimination against them.     

An evaluation of the life cycle effects of minimum pensions on retirement behavior

In this paper we explore the effects of the minimum pension program on welfare and retirement in Spain. This is done with a stylized life cycle model which provides a convenient analytical characterization of optimal behavior. We use data from the Spanish Social Security to estimate the behavioral parameters of the model and then simulate the changes induced by the minimum pension in aggregate retirement patterns. The impact is substantial: there is a threefold increase in retirement at 60 (the age of first entitlement) with respect to the economy without minimum pensions, and total early retirement (before or at 60) is almost 50% larger.

Minimum safety standard,consumers’ information and competition

This paper explores the effects of a standard influencing care choice with an endogenous market structure. Under duopoly, firms compete either in prices or in quantities. Firm(s) may increase the probability of offering safe products by incurring a cost. A standard may correct a safety underinvestment by firms. It is shown that the market structure (duopoly or monopoly) linked to the standard depends on the available information. Under perfect information about safety for consumers, the selected standard is always compatible with competition. The absence of standard due to safety overinvestment by firms only emerges under competition in quantities and a relatively low cost of safety improvement. Under imperfect information about safety for consumers, the selected standard often leads to a monopoly situation, essential for covering the cost of safety improvement. However, for relatively high values of this cost, a standard cannot impede the market failure arising from the lack of information.      

The Link Between Wages and Productivity in Spain

This paper examines the effect of productivity on wages for Spanish industrial sectors by developing a model that captures effects from both sector‐specific and aggregate variables. The results show that a dual behaviour can be inferred, at the sector level, in the wage‐setting mechanism. It is also found that the linkage between wages and productivity varies over time. Some explanations for the increase in wage dispersion are provided, focusing on the increasing decentralisation in wage bargaining after 1986. Finally, we cast some light on the theoretical structure underlying the labour market.     

Charitable Giving of Alumni

A bstract . This research examines the "age-donation" profile of gift-giving alumniai a large public university , based on a pooled micro-data random sample of 4,242 alumni (1926/27-1989/90 graduates) who gave cash gifts during the 1975/76-1989/90 fiscal years. The covariance regression model results indicate lack of statistically significant difference between gift-giving women and men. However, the School of Business graduates , alumni who proceeded to obtain graduate degrees from this university, and alumni members of non-Greek social organizations gave significantly more. Moreover, alumni contributions varied systematically over the business cycle and a 1962 Federal Court Order to desegregate the university racially reduced donations but not significantly. Given the 63-year cycle studied, the growth rates of alumni donations of money are projected to decline after roughly age 52, which falls short of the typical retirement age.
