Minimum Wages, Market Inflexibilities, and Female Employment in Select OECD Countries

Using international and intertemporal variations in minimum wages, employment protection laws, minimum wage regulations and female work behavior within the OECD, empirical analysis provide evidence that higher minimum wages are associated with lower female labor force participation and employment. This association is more significant in countries with more stringent employment protection laws, lower female tertiary educational enrollment and higher fertility. In addition to the extensive margin analysis, it is shown that minimum wage levels are positively correlated with the ratio of part-time workers. That is, minimum wages are associated with not only lower participation and employment rates among women but also with higher marginalization of female work. This association is stronger in countries with more inflexible labor markets and less active labor market policies. Moreover, existence of a subminimum wage for youths implies further reduction of employment while increasing part-time job incidence for females, when the minimum wage increases.Labor market regulations, female work, minimum wage, OECD, time series data

Welfare Reform and Children's Short-Run Attainments: A Structural Approach

In this paper, we develop a dynamic structural model of single mothers' work and welfare participation decisions while their children are young. This model is used to measure the effects of mothers' decisions on short run attainments of the children of NLSY 79. Using PIAT Math test score as a measure of attainment, we find that both single mothers' work and welfare use in the first five years of their children's lives have a positive effect on children's outcomes, but this effect declines with initial ability. The higher the initial ability of a child, the lower the positive impact work and welfare have. In fact, in the case of welfare the effect is negative if a child has more than median initial ability. Furthermore, we find that the work requirement reduces a single mother's use of welfare. However, the net effect of the work requirement on a child's test score depends on whether the mother's work brings in enough labor income to compensate for the loss of welfare benefits. We also look at the implications of the welfare eligibility time limit and maternal leave policies on children's outcomes.Welfare reform, childhood cognitive ability, female work, dynamic choice model, maximum likelihood

Minimum Wages, Labor Market Institutions, and Female Employment

The authors investigate the employment consequences of minimum wage regulation in 16 OECD countries, 1970-2008. Their treatment is motivated by Neumark and Wascher’s (2004) seminal cross-country study. Apart from the longer time interval examined, a major departure is the authors’ focus on prime-age females, a group often neglected in the minimum wage literature. Another is their deployment of time-varying policy and institutional regressors. The average effects they report are consistent with minimum wages causing material employment losses among the target group. Their secondary finding is that minimum wage increases are more associated with (reduced) participation rates than with elevated joblessness. Further, although the authors find common ground with Neumark and Wascher as regards the role of some individual labor market institutions and policies, they do not observe the same patterns in the institutional data. Specifically, prime-age females do not exhibit stronger employment losses in countries with the least regulated markets.Minimum wages, minimum wage institutions, prime-age females, disemployment, participation, unemployment, employment protection, labor standards, labor market policies, unions

Minimum Wages, Labor Market Institutions, and Female Employment and Unemployment: A Cross-Country Analysis

This paper estimates the effect of minimum wage regulation in 16 OECD countries, 1970-2008. Our treatment is motivated by Neumark and Wascher's (2004) seminal cross-country study using panel methods to estimate minimum wage effects among teenagers and young adults. Apart from the longer time interval examined here, a major departure of the present study is the focus on prime-age females, a group typically neglected in the component minimum wage literature. Another is our deployment of time-varying policy and institutional regressors. Yet another is our examination of unemployment and participation outcomes in addition to employment effects. We report strong evidence of adverse employment effects among adult females and lower participation, even if the unemployment effects are muted. Although we report some similar findings to Neumark and Wascher as to the role of labor market institutions and policies, we do not observe the same patterns in the institutional data; in particular, we can reject for our target group their finding of stronger disemployment effects in countries with the least regulated markets.minimum wages, wage fixing machinery, prime-age females, employment, unemployment, participation, cross-section time-series data, OECD countries, labor market flexibility, labor market institutions and policies

Confessions of an Internet Monopolist: Demand Estimation for a Versioned Information Good

We investigate profit-maximizing versioning plans for an information goods monopolist. The analysis employs data obtained from a web-based field experiment in which potential buyers were offered information goods in varied price-quality configurations. Maximum simulated likelihood (MSL) methods are used to estimate parameters describing the distribution of utility function parameters across potential buyers of the good. The resulting estimates are used to examine the impact of versioning on seller profits and market efficiency.Versioning, price discrimination, field experiment, maximum simulated likelihood

Predicting Employment Effects of Job Coaching

Providing employment-related services, including supported employment through job coaches, to individuals with developmental disabilities has been a priority in federal policy for the past twenty years starting with the Developmental Disabilities Assistance and Bill of Rights Act in 1984. We take advantage of a unique panel data set of all clients served by the SC Department of Disabilities and Special Needs between 1999 and 2005 to investigate whether job coaching leads to stable employment in community settings. The data contain information on individual characteristics, such as IQ and the presence of emotional and behavioral problems, that are likely to affect both employment propensity and likelihood of receiving job coaching. We control for unobserved heterogeneity and endogeneity using fixed effects and instrumental variable models. Our results show that unobserved individual characteristics and endogeneity strongly bias naive estimates of the effects of job coaching. However, even after controlling for these, an economically and statistically significant effect remains.

The Effects of Single Mothers' Welfare Participation and Work Decisions on Children's Attainments

This research examines the effects of mothers' welfare and work decisions on their children's attainments using two types of estimation methods in Stata: (1) an instrumental variables (IV) and (2) a nonlinear simultaneous equation estimation. The estimator employs sibling comparisons in a random effect framework and an instrumental variables approach to address the unobserved heterogeneity that may influence mothers' work and welfare decisions. We use the popular Stata command -ivreg2- to estimate the coefficients. Since production function of a child's ability can be written as a nonlinear function in a mother's decisions, we can also use the -nlsur- command to simulatneously estimate the production function as well as the (first-stage) IV projections. We focus on children who were born to single mothers with twelve or fewer years of schooling. IVs in this study are a mother's expected years of work and welfare use during childhood. The identification comes from the variation in mothers' different economic incentives that arises from the AFDC benefit structures across U.S. states. The estimates imply that, relative to no welfare participation, participating in welfare for one to three years provides up to a 5 percentage point gain in a child's Picture Individual Achievement Test (PIAT) scores. The negative effect of childhood welfare participation on adult earnings found by others is not significant if one accounts for mothers' work decisions. At the estimated values of the model parameters, a mother's number of years of work contributes between $3,000 and$7,000 1996 dollars to her child's labor income, but has no significant effect on the child's PIAT test scores. Finally, children's number of years of schooling is relatively unresponsive to mothers' work and welfare participation choices.
