Microdata Access and Labor Market Research: The U. S. Experience

Summary: The paper illustrates the value of broad researcher access to survey and administrative microdata using examples drawn from the U. S. experience, outlining how analyses of trends in earnings inequality, poverty and employment dynamics using such data have benefited policy makers and contributed to improvements in statistical agency data products. Methods of facilitating researcher access, including the release of public use files, the use of licensing agreements, and the establishment of research data centers, are discussed. * The author thanks Anne Polivka, Marilyn Seastrom and two anonymous referees for helpful comments on an earlier draft of the paper.

Challenging the Rhetoric of Choice in Maternal Labour‐Force Participation: Preferred Versus Contracted Work Hours

The notion of choice in maternal labour‐force participation (LFP) is a contentious one, with assertions that LFP is a direct result of either personal inclinations, such as employment commitment or external factors, such as historically available opportunities. This article suggests an alternative framework for understanding and testing choice in LFP using preferred versus contracted work hours. It explores these constructs quantitatively in a group of working mothers (N = 275) with dependent children and investigates qualitatively the underlying reasons for discrepant preferred versus contracted work hours in a sub‐sample of these women with under‐school‐aged children (N = 20). The results show that nearly two‐thirds of women working full time would prefer to work part time and the major reasons for not acting on their preferences is because of the nature of the job and the lack of career opportunities available for part‐time employees.

Public–private wage differential and gender gap in Latin America: Spoiled bureaucrats and exploited women?

This paper uses a rich collection of household surveys to investigate the wage differential between the public and private sectors in 13 Latin American countries. It also studies how the sector of employment affects the gender wage gap. Contrary to what is commonly thought, it is found that, in the majority of Latin American countries, there is a premium associated with working in the public sector. It is also found that the premium is often higher for women than for men but that this difference does not compensate for the wide gender gap.
