THE EFFECT OF MINIMUM WAGES IN THE PRESENCE OF FRINGE BENEFITS: AN EXPANDED MODEL

Firms may react to a minimum wage hike by reducing their expenditures on fringe benefits. This possibility is incorporated into an expanded model of minimum wages. A set of predictions that differentiate this expanded model from current minimum wage models is derived and tested. The expanded model is shown to better predict the effect of minimum wages on labor force participation, quit rates, and prices than previous models. An interesting result of the expanded model is that a covered worker may be worse off due to a minimum wage hike even if he retains his job.     

The Effects of Prevailing Wage Laws: A Comparison of Individual Workers'' Wages Earned on and off Prevailing Wage Construction Projects

I evaluate the effects of prevailing wage laws using a unique data set that shows the wages paid to workers on prevailing wage projects and the wages paid to the same workers during the same time period for work on projects not covered by prevailing wage regulations. The wage comparison shows that workers are generally paid more for work on prevailing wage projects than they are for work on non-prevailing wage projects. Thus, prevailing wage laws likely do increase the cost of public construction. In addition, to the extent that the quality of construction is improved, prevailing wage laws appear to be an inefficient mechanism by which to achieve additional quality, as the regulations often result in workers being paid more than they earn in the private market.     

Minimum wages and the wessels effect in a monopsony model

The Wessels model suggests that firms respond to increases in the minimum wage rate by decreasing the level of fringe benefits — an action which produces an inefficiency effect that lowers workers’ utility and the supply of labor. Standard models of monopsony, however, argue that wage floors prevent the exercise of market power and increase employment. I show that wage floors, even with fringe benefit curtailment, may increase employment by lowering the marginal expense of labor. Employee utility and employment will rise somewhat but not as much had the firm acted competitively in setting both wages and fringes.

Noncitizen Employment and the Wages of Healthcare Support Workers in the US

This study examines the relative wages of citizens and noncitizens employed as healthcare support workers as well as examines the effect of noncitizen support worker employment on the wages of citizen support workers. Relative wage findings reveal noncitizen support workers with less than eight years of US residency receive a noncitizen-citizen wage discount statistically significantly greater than the legal maximum of 5% below the local prevailing wage. These low relative wage levels could contribute to lower wages for citizen support workers, however elasticity of substitution findings suggest noncitizen support workers are not close substitutes for healthcare support workers who are US citizens. In addition, wage effect findings do not reveal a negative influence of noncitizen employment on the wages of native born US citizen support workers, while these findings reveal a relatively small wage decline for naturalized support workers. These findings are consistent with the citizen status job heterogeneity hypothesis. Nonetheless, finding noncitizen-citizen wage differences does not allow for ruling out the possibility of weak enforcement of prevailing wage legislation and possible employment of undocumented workers.     

Countercyclical union wage premium? Evidence for the 1980s

Empirical results based on pooled male data from the Panel Survey of Income Dynamics indicate an overall union wage premium of about 11.92 percent for the 1980s. In response to fluctuations in local labor market conditions, proxied by the local unemployment rate, a much more flexible wage-setting process is found in the nonunion sector relative to the union sector. The long-term effect of unemployment on nonunion real wages suggests an approximate 0.6 percent decline for every one percentage point increase in unemployment, a statistically significant reduction, but the long-term effect of unemployment on real wages of union members is negligible. The union wage premium ranges between 11.6 to 12.3 percent for the sample years. Even though union wages are insensitive to short-run fluctuations in local labor market conditions, and are somewhat countercyclical in nature, widespread union wage concessions which occurred during the 1980s may now be exerting a downward pressure on union wages.

Is there a wage cost for employees in family‐friendly workplaces? The effect of different employer policies

This article assesses the wage impact of different family‐friendly employer policies: in‐kind or in‐cash child‐related benefits and flexible work schedule arrangements. We use French matched employee–employer data with a rich set of indicators of family‐friendly benefits, and we pay attention to the possible endogeneity of worker–employer matching. Our results show that the provision of in‐cash or in‐kind benefits is associated with higher wages for women, while flexible work schedules have no significant effect on wages. Our results lead us to reject the hypothesis of compensating wage differentials: women do not appear to face a trade‐off between wages and a better work–life balance. Our findings are more in line with the enhancing productivity theory: in‐kind benefits reduce the time devoted to household activities and alleviate conflict between professional life and family life, thereby improving women's work effort and productivity. This is not the case for flexible work arrangements, which may be perceived as negatively related to workers’ commitment to their job.     

Unions and wages in Nevada’s hotel-casino industry

A significant union presence in the Las Vegas hotelcasino industry juxtaposed to the near absence of union representation in the Reno area provides a unique setting to study union wage effects in the industry. Results of the analysis using state wage survey data indicate that after controlling for unobserved heterogeneity in the two locations median wages in occupations in Las Vegas with substantial union coverage are 24 percent higher than wages in identical occupations in Reno.     

Unions and wage inequality

Summary and Conclusions The impact of unions on the structure of wages has recently attracted renewed interest as analysts have struggled to explain the rise in earnings inequality in several industrialized countries. Canada, the United Kingdom, and the United States provide a potentially valuable set of countries for examining this question. All three countries now collect comparable data on wages and union status in their regular labor force surveys. Several features of the collective bargaining institutions of these countries make them suitable for studying the relationship between unions and wage inequality. Bargaining is highly decentralized; there are no general mechanisms for extending collective bargaining provisions beyond the “organized” sector; and the fraction of the work force covered by collective bargaining is relatively modest. Thus it is possible to compare the structure of wages for workers covered by union contracts to those who are not covered, and potentially infer the effect of unions on overall wage inequality.     

The threat of unionism and wage-coverage effects

This study finds that the union/nonunion wage differential decreases with local labor-market coverage. In general, SMSA coverage has a negligible impact on union wages, and nonunion wages increase significantly with coverage. This is consistent with strong threat effects operating at the local labor-market level. As with most other wage-coverage studies, however, union wages increase more quickly with industry coverage than do nonunion wages. These results support the argument that distinctly different economic processes underlie local labormarket and industry-coverage effects. Economies in the provision of union services imply that union threat effects will be most salient at the local labor-market level. Industry wage-coverage relationships are dominated by the positive effect of product-market coverage on union bargaining power. Estimated coverage effects vary by major industry groupings and are sensitive to changes in the specification of the wage equations.

Prevailing wage laws and black employment in the construction industry

As a by-product of analysis of state-level prevailing wage laws applying to public construction projects, a strongly inverse correlation was found between black employment and strength of prevailing wage law. Although black construction employment is generally below what it averages in other sectors, it is closer to parity in states where there is no prevailing wage law, and progressively less so in groups of states that have progressively stronger laws.     

Relative wages and exit behavior among registered nurses

I examine the exit decision of registered nurses using the longitudinal data files generated by the March Current Population Surveys (CPS) from 1983 through 1994. By examining the wages of workers outside of nursing, a measure of the reservation wage is constructed and related to the decision to leave nursing, either for an alternative job or to exit employment. My results indicate that nurses respond to outside wage opportunities. A one standard deviation decrease in the difference between the actual and predicted log wage results in an 8 percent increase in the exit of nurses. Secretaries, however, are shown to have a much greater sensitivity to outside wages due to the lower degree of occupation-specific training required for secretarial jobs. A similar increase in the wage gap for secretaries results in an 18 percent increase in turnover. RNs employed in hospitals, covered by a union contract, and employed in the public sector are relatively attached to the nursing profession.

Participation in union activities: A multivariate analysis

Multivariate analysis is used to estimate a model of member participation in local union activities. A sample of 387 members of the UAW living in the Detroit area was drawn from the1961 Detroit Area Study: Work Group Influence and Political Participation. It was hypothesized that participation would be positively associated with level of schooling, current wages, seniority, skilled jobs, job dissatisfaction, dissatisfaction with the local union, desire for another job, commitment to the labor movement, and getting along with others. OLS and Logit estimation techniques were used and support was found for all hypotheses except those related to wage levels and seniority.     

The Ross-Dunlop debate and union wage concessions: A median voter analysis

The Ross-Dunlop debate concerns the extent to which unions take into account the trade-off between wages and employment in formulating their wage demands. This paper develops a median voter model of union behavior that offers a new approach to resolving the Ross-Dunlop debate. The model shows that when the binding constraint on the median union member in the seniority distribution is the threat of layoff, the union will behave as a “Dunlop-type” union; when the binding constraint is the cost of striking, the union will behave as a “Ross-type” union. The model is then applied to the related issue of union wage concessions. Two questions are examined: Under what conditions will a union agree to wage concessions? How large a cut in wages will be accepted?     

Workers, Unions, and Takeovers

How do takeovers affect workers?? wages and job security in the short-run? What role does the labor union play in mitigating these effects? I answer these two questions by analyzing wage and employment outcomes of over 4,000 public firms that were acquired between 1981 and 2002, using establishment-level data from the U.S. Census Bureau. I find that target establishments exhibit a net contraction in wages and employment, relative to comparable establishments after takeovers. Targets?? establishments in more unionized industries experience worse wage and employment outcomes after takeovers. These adverse effects are exacerbated when the establishment is located in a state with Right-to-work laws where unions face a less favorable bargaining environment. These findings indicate that target firms?? employees are negatively affected by takeovers and that their labor unions do not mitigate these negative effects.     

Union-Nonunion differentials and establishment size: Evidence from the NLSY

We provide new empirical evidence on union-nonunion differentials using the 1990 wave of the National Longitudinal Surveys of Youth (NLSY) data set which allows us to examine a broader set of fringe benefits than most other studies and provides a rich set of control variables. Our major finding is that the union effect decreases with establishment size for both components of the compensation structure, i.e., wages and fringe benefits. An earlier version of this paper was presented at the Southern Economic Association conference in Washington, DC in 1996. We thank Tom Hyclak and other session participants.

“Family-Friendly” Fringe Benefits and the Gender Wage Gap

Evidence suggests a large portion of the gender wage gap is explained by gender occupational segregation. A common hypothesis is that gender differences in preferences or abilities explain this segregation; women may prefer jobs that provide more “family-friendly” fringe benefits. Much of the research provides no direct evidence on gender differences in access to fringe benefits, nor how provision affects wages. Using data from the National Longitudinal Survey of Youth 1979, we find that women are more likely to receive family-friendly benefits, but not other types of fringe benefits. We find no evidence that the differences in fringe benefits explain the gender wage gap.

Union density effects in the supermarket industry

Unions provide higher than competitive wages for members, but their effect on non-union wages is not clear. We investigate the effect of union density on supermarket wages from 1986 to 1993, a period of declining real wages and declining union membership. Full-information maximum likelihood techniques are used to estimate log wage equations for both the union and nonunion sectors. Decomposition techniques then separate the union wage premium into the relative effects of densities and union membership. We find a significant, positive effect of union density for both union and nonunion employees. This effect explains approximately one-third of the union-nonunion wage differential. This research was conducted while Johansson was a graduate research assistant at the University of Minnesota.     

Regional wages and subjective measures of employment opportunities

We utilise a rich set of regional labour market variables to explain regional variation in Norwegian manufacturing wages. In particular, regional indicators of labour market conditions are computed from survey data in which respondents are asked to evaluate local employment opportunities. We find that average reported satisfaction with local job prospects and other survey-based indicators perform better in regional wage equations than traditional labour market variables, including the regional unemployment rate. Our results suggest that subjective measures of employment opportunities provide useful information about wage pressure.     

Whatever happened to the monopoly theory of labor unions?

This paper argues that unions act in accord with the conventional cartel or monopoly model. The basic premise is that it is useful to ask what a “union maximizes” because if more wealth is available, union decision-makers have an incentive to capture it for themselves or their membership. In the formal model, unions negotiate wage rates which maximize the monetary surplus above the supply price of labor, providing an endogenous answer to the questions of how union employment and wages are simultaneously determined. Comparative static analysis yields empirical predictions about the behavior of union employment, wage rates, and union-nonunion wage differentials. I would like to acknowledge helpful comments by Richard Anderson, Ray Battalio, Hugh Macaulay, Michael Ormiston and Akira Takayama on earlier drafts of this paper. The usual caveat applies.
