Interindustry part-time and full-time wage differentials: regional and national analysis

This paper provides more evidence that the wage differential is far smaller than is suggested by simple comparison of gross wages of full-time and part-time workers. It is noted that to obtain a more reasonable measure of the full-time and part-time wage differential, it is necessary to adjust for differences in workers' characteristics, labour market conditions and sample selection. It is found that, in general, full-time and part-time workers exhibit different personal characteristics. In particular, full-time workers possess more human capital and experience than part-timers. Also, labour market conditions such as unions and pension plans favour full-timers. These differences may partly account for the wage disparity between full-time and part-time workers. It was noted that the nonrandomness of the workers into full-time and part-time jobs influences the wage determination of both full-time and part-time workers. The results indicate that the adjustment of the wage equations to reflect the above mentioned differences reduces the national wage differential between full-time and part-time workers by 10%. The reduction is even larger across regions and industries. Another finding was that the wage determination processes between full-time and part-time workers do differ.     

Wage differentials by sector and gender: a quantile analysis for the Spanish case

This paper analyses existing wage differentials between workers in the public and private sectors and by gender in Spain. This analysis is run throughout the entire earnings distribution and observed wage differentials are decomposed into a part explained by differences in productive characteristics and a part due to differences in returns to such characteristics. Our results show that public sector workers tend to earn higher wages than private employees, although most of this sector wage gap is due to better public workers’ productive characteristics. A wage premium in favour of men is also found in both the public and private sectors, with the gender wage gap greater at the top of the earnings distribution.     

WAGES AND EMPLOYMENT IN THE U.S. APPAREL INDUSTRY

This article uses individual-level data from the U.S. Census, Public Use Microdata Sample (PUMS), to examine wages and employment in the U.S. apparel industry. Total employment in this sector has been falling since 1970, and its overall average wage is the lowest of 25 industry aggregates. But disaggregation by gender, education, and nativity reveals that groups of highly educated male native workers earn higher average wages in apparel than in other industries. Moreover, after adjusting for observed individual differences in human capital (in addition to the three characteristics used to form worker subsets), highly educated male natives earn positive wage premiums in this sector. In contrast, most categories of immigrants and female natives earn relatively low average wages and experience negative wage premiums in apparel. This variation in the adjusted industry wage premiums across worker groups may be related to apparel's relative exposure to imports and immigrant workers.     

Incidence and Duration of Unemployment Spells: Implications on the Wage Differentials of Part-Time and Full-Time Workers

This article analyzes the extent to which incidence of unemployment and duration of unemployment spells affect the wage differentials between full-time and part-time workers. The estimation results of a sample selectivity bias–adjusted wage equation reveal that high incidences of unemployment are associated with low wages for both full-time and part-time workers. However, the reduction in wages due to incidence of unemployment is larger for full-time workers in high-paid jobs than for their part-time counterparts. Duration of unemployment spells affects full-time and part-time workers differently. In general, longer unemployment spells tend to increase the wages of full-time workers but tend to depress the wages of part-time workers. Although the probability of unemployment is not a factor in explaining the wage differential, the duration of unemployment accounts for a substantial portion (about 66.6% in full sample) of the wage differential that exists between full-time and part-time workers.     

Are labor markets segmented in developing countries? A semiparametric approach

We test the hypothesis that observably similar workers earn higher wages in the formal sector than in the informal sector in developing nations. Using data from Argentina's household survey and various definitions of informal employment, we find that on average, formal wages are higher than informal wages. Parametric tests suggest that a formal premium remains after controlling for individual and establishment characteristics. However, this approach suffers from several econometric problems, which we address with semiparametric methods. The resulting formal premium estimates prove either small and insignificant, or negative. Neither do we find significant differences in measures of job satisfaction between the two sectors. We invoke these results to question the mainstream view that labor markets are segmented along formal/informal lines in developing nations such as Argentina.     

THE IMPACT OF BODY WEIGHT ON OCCUPATIONAL MOBILITY AND CAREER DEVELOPMENT

This article examines the relationship between individuals' weight and employment decisions over the life cycle. I estimate a dynamic stochastic model of individuals' annual choices of occupation, hours worked, and schooling. Evidence suggests that heavier individuals face higher switching costs when transitioning into white‐collar occupations, earn lower returns to experience in white‐collar occupations, and earn lower wages in socially intensive jobs. I simulate a hypothetical antidiscrimination policy treating obese workers as a protected class. Although such a policy would reduce gaps in occupational attainment, it would have little effect on the observed divergence in wages between obese and nonobese workers.     

BEAUTY AND PRODUCTIVITY: THE CASE OF THE LADIES PROFESSIONAL GOLF ASSOCIATION

There is evidence that attractive looking workers earn more than average looking workers, even after controlling for a variety of individual characteristics. The presence of such beauty premiums may influence the labor supply decisions of attractive workers. For example, if one unit of a product by an attractive worker is more rewarded than that by her less attractive coworker, the attractive worker may put more effort into improving her productivity. We examine this possibility by analyzing panel data for individual female golfers participating in the Ladies Professional Golf Association (LPGA) tour. We found that attractive golfers recorded lower than average scores and earn more prize money than average looking players, even when controlling for player experience and other variables related to their natural talents. This finding is consistent with the notion that physical appearance is associated with individual workers' accumulation of human capital or skills. If the human capital of attractive workers is at least partly an outcome of favoritism toward beauty, then the premium estimates obtained by previous studies may have been downwardly biased.

Cities, Workers, and Wages: A Structural Analysis of the Urban Wage Premium

Workers earn higher wages in cities vs. rural areas. This gap could arise because cities make workers more productive, or it could be the result of a non-random selection of workers into cities based on their ability and their endogenous history of career choices. To untangle these issues, this paper estimates a dynamic programming model, which embeds the choice of residing in a city or rural area within a model of career choices over time. After controlling for all the sources of selection and endogeneity, the estimates indicate that a given worker does earn more in the city for white-collar work, but not for blue-collar work. In addition, city work experience is found to be worth more than rural work experience in the rural area for white-collar work, but not for blue-collar work. These results support the interpretation that cities make white-collar workers more productive and suggest that workers may consider moving to the city not only in terms of locational choice, but also as a form of human capital investment.     

Export Destination,Product Quality and Wages in a Middle‐Income Country. The Case of South Africa

A robust finding in the firm‐level literature is that exporting firms pay higher wages. Using South African data this paper investigates the relationship between export destination and wages at a worker level. South Africa, a middle‐income country, has two distinct main export markets—a regional market where per capita incomes are lower than at home, and an international market with higher per capita incomes. Our estimates show that workers in firms that export to the region earn less than those that produce for the domestic market. Those in firms that export outside the region earn more than either domestic producers or region‐only exporters. Much of this difference in wages can be explained by the premium the different types of exporters pay for skills. These results support previous studies which suggest that export destination is related to product quality which in turn is related to worker quality and therefore wages.     

Does Raising the Minimum Wage Help the Poor?*

What is the impact of raising the minimum wage on family incomes? Using data from the 1994–1995 to 2002–2003 Survey of Income and Housing, the characteristics of low-wage workers are analysed. Those who earn near-minimum wages are disproportionately female, unmarried and young, without postschool qualifications and overseas born. About one-third of near-minimum-wage workers are the sole worker in their household. Due to low labour force participation rates in the poorest households, minimum-wage workers are most likely to be in middle-income households. Under plausible parameters for the effect of minimum wages on hourly wages and employment, it appears unlikely that raising the minimum wage will significantly lower family income inequality.     

Public–Private Sector Wage Differentials in Australia

This paper examines public–private sector wage differentials in Australia. After controlling for observed characteristics and individual fixed effects, we show that on average workers in the public sector earn about 5.1 per cent more in hourly wages than those in the private sector. The wage premium is slightly higher for females than males. Using a panel data quantile regression model with fixed effects, we show that the positive wage effects of public sector employment are heterogeneous, with comparatively larger impact at the lower end of the wage distribution than at other parts. We also find evidence of heterogeneity in the public sector wage premiums by qualification, time period, occupation and state/territory.     

New evidence on public sector wage differentials

This paper examines the nature of wage differentials for men and women in the public sector, using a sample selection approach. This includes the self-selection that occurs in the sectoral choice process as well as the selection that arises in context of the labour force participation decision of men and women. Using 1991 Current population Survey data, it is found that male workers in the public sector on an average earn higher wages than male private sector workers, whereas the wage premium earned by women is undermined by a slightly greater degree of discrimination in the public sector     

Duration of disability,job mismatch and employment outcomes

Workers with disabilities have functional limitations that affect their productivity in some, but not necessarily all, jobs. Workers who find a job that is a good match for their functional limitations (i.e. a job where their limitations have little or no impact on important job functions) should expect better employment outcomes (e.g. higher wages, longer job tenure) than workers with similar disabilities who are mismatched in their jobs. Merging data from the Survey of Income and Program Participation with O*Net data on job demands, we construct two continuous measures of job mismatch for workers with physical disabilities. We then extend the literature on disability and employment by exploring relationships between duration of disability, job mismatch, wages and hours worked. The results indicate that workers with long durations of disability are employed in jobs that are a better match to their physical limitations than are similar workers with shorter durations of disability. And, workers who are mismatched earn lower wages and work fewer hours than their counterparts whose jobs are a better match. Overall, the findings suggest that disability employment policies should include systematic efforts to help workers with disabilities find good job matches.     

COMPARING FEDERAL AND PRIVATE‐SECTOR WAGES WITHOUT LOGS

I use Current Population Survey data from 2005 through 2010 to compare the wages of federal employees and workers in the private sector who have similar observable characteristics. The distribution of wages differed drastically between the federal and private sectors. In particular, I find that federal employees with no more than a high school diploma earned 21% more, on average, than their private‐sector counterparts, whereas those with a professional degree or doctorate earned 23% less. Overall, the average of federal wages was about 2% higher than the average wage of similar private‐sector workers. Other researchers have found larger differences because they used log‐linearized models, which result in comparisons of geometric means. I show that arithmetic means are more relevant in the context of the relationship between a government's compensation policy and its budget. The discrepancy between differences in arithmetic and geometric means occurs because the wages of federal employees were much less dispersed than those of employees with similar characteristics in the private sector.

Wage Differentials between the State and Private Sectors in Moscow

In this study the 1997 Russian Labor Force Survey is used to investigate wage differentials between the state and the private sector in the city of Moscow. Our analysis demonstrates that substantial differences exist between private and state sector wages. We estimate the gap between private and state sector wages to be 14.3 percent for men and 18.3 percent for women. We also find gender differences in wages. Men in the private sector earn on average 23.7 percent more than women. The gender wage gap in the state sector is even higher at 32.5 percent. In the state sector, wages for both men and women increase as years of tenure increase. But in the private sector this is only true for men; women earn no return to tenure. The probability of employment in the private sector decreases with age and tenure.     

Employer and Employee Ignorance in Developing Countries: The Case of Trinidad and Tobago

The authors examine the degree of employer and employee ignorance about reservation and offer wages in Trinidad and Tobago and find this to be considerable. On average employers pay more than 26% above workers’ reservation wages, while employees earn 22% less than the maximum wage on offer, ceteris paribus. However, there are some differences across sub‐groups of jobs, particularly with regard to individuals’ lack of information about the best wage offers. Some differences are also found compared to previous results for developed nations, although the level of ignorance does not appear to be higher in Trinidad and Tobago.     

The wage effects of training in Portugal: differences across skill groups,genders, sectors and training types

This article investigates the determinants and wage effects of training in Portugal. In a first stage, we show that there are considerable differences in training participation across groups of workers, with elder and low educated individuals participating substantially less. In a second stage, we show that training has a positive and significant impact on wages. The estimated wage return is about 30% for men and 38% for women. Discriminating between levels of education and working experience and the public and private sector reveals important differences across categories of workers. We find that women, low educated workers and workers with long working experience earn larger returns from training. The average effect of training is similar in the private sector and the public sector. However, differences across experience groups are larger in the private sector, while differences across education groups are larger in the public sector. We use three alternative classifications of training activities and find that training in the firm, training aimed to improve skills needed at the current job and training with duration less than a year are associated to larger wage gains.     

Worker flows, job flows and firm wage policies

Like many transition economies, Slovenia is undergoing profound changes in the workings of the labour market with potentially greater flexibility in terms of both wage and employment adjustment. To investigate the impact of these changes, we use unique longitudinal matched employer‐employee data that permits measurement of employment transitions and wages for workers and enables links of the workers to the firms in which they are employed. We can thus measure worker flows and job flows in a comprehensive and integrated manner. We find a high pace of job flows in Slovenia especially for young, small, private and foreign‐owned firms and for young, less educated workers. While job flows have approached the rates observed in developed market economies, the excess of worker flows above job flows is lower than that observed in market economies. A key factor in the patterns of the worker and job flows is the determination of wages in Slovenia. A base wage schedule provides strict guidelines for minimum wages for different skill categories. However, firms are permitted to offer higher wages to an individual based upon the success of the worker and/or the firm. Our analysis shows that firms deviate from the base wage schedule significantly and that the idiosyncratic wage policies of firms are closely related to the observed pattern of worker and job flows at the firm. Firms with more flexible wages (measured as less compression of wages within the firm) have less employment instability and are also able to improve the match quality of their workers.

Employment shifts, economic reform and the changes in public/private sector wages in Mexico: 1987–1997

Over the last decade, the public sector in Mexico experienced substantial fiscal reform, divestiture of public enterprises, and the elimination of many regulations affecting pay and employment. This study analyzes the changes in the public/private sector differences in wages during the 1987–1997 period. The results from analyzing microdata from the Encuesta Nacional de Empleo Urbano show that relative public sector wages increased from 1987 to 1997. Most of the relative wage increase in the public sector can be explained by increases in the price of skills and by changes in sorting across sectors. The results have important public policy implications since they suggest that public sector workers earn more and their wages have grown faster than those of their private sector counterparts. As such, policies contemplating public sector reform should take into account the effect of these measures on the inter-sectoral income distribution and the overall economic growth.

The Spatial Determinants Of Wage Inequality: Evidence From Recent Latina Immigrants In Southern California

Abstract

Recent Latina immigrants to the United States earn lower hourly wages than any other broad demographic group. This paper investigates the role space and scale play in shaping the employment opportunities and wages this group receives in Southern California relative to others there. Results suggest that, although individual factors such as education, experience, and ability to speak English are important, spatial forces also influence wages. Access to jobs, particularly low-skilled jobs and those held by Latinos, as well as ethnic neighborhood networks, explain a large share of the variation in hourly wages. The paper provides evidence that labor-market scales differ across groups within US metropolitan areas, with recent Latina immigrants being more geographically constrained and hence more dependent on local opportunities and resources than other workers, with the exception of black women.
