Analysis of the practice of job evaluation in the metal industry in Turkey

Job evaluation's main aim is to establish a fair wage structure. Its main principle is ‘equal pay for equal work’. ‘Metal Industry Job Grouping System’ (MIDS) has been in the metal industry in Turkey for more than 20 years. The results of the practice of the system were measured by the Gini coefficient. By the findings, the average wages of the job groups are different enough from each other by their job groups in the way the wage of the bigger number job group is higher than the smaller except the job group two in the industry. However, the wages are far from the principle ‘equal wage for equal job’ within the same job itself. In addition, the workers make use of bonuses and social benefits. The effect of social benefits of them on the wage structure is positive within the same job group and negative between different job groups within the same company. Nevertheless, the effect of both bonuses and social benefits on the wage structure is negative between the companies because, between them they are different from each other. Job group and seniority affect the wage structure. Seniority has a socio-psychological self-producing dynamic. The distribution of seniorities within the same job group has negative effects on the wage structure. However, this fact for each worker disappears for the long term since the worker of today who has short-term seniority will be the one of tomorrow who has long-term seniority. Therefore, for each worker, the wage structure gets closer to the principle ‘equal wage for equal job’ within the same job group itself over time.     

Job and wage mobility with minimum wages and imperfect compliance

We propose a job search model with minimum wage regulations and imperfect compliance to explain the doubling of the mean and variance of hourly earnings of white males during the first 18 years of labor market experience. The model encompasses job mobility and on‐the‐job wage growth as sources of wage dynamics, and is estimated by simulated generalized method of moments using data from the National Longitudinal Survey of Youths 1979. Our estimates provide a good fit for the observed levels and trends of the main job and wage mobility data, and for the increase in the mean and variance of wages over the life cycle, as well as for the fall in the fraction of workers paid below the minimum wage. Job mobility explains 40–50% of the observed wage growth. Increases in the minimum wage and/or compliance deliver small effects on the wage distribution and the nonemployment rate.

Wage Growth Implications of Fixed-Term Employment: An Analysis by Contract Duration and Job Mobility

Focusing on Spain, where fixed-term workers account for a third of the wage and salary workforce, we examine the wage growth implications of fixed-term employment of varying duration while distinguishing between wage growth occurring on-the-job versus via job mobility. Wage growth among employees with indefinite work contracts largely occurs via job mobility, whereas fixed-term workers gain via job mobility as well as on-the-job. Consequently, job stayers with fixed-term contracts a year ago narrow their wage gap with respect to similar counterparts with indefinite-term contracts. Yet, this effect is solely driven by the 10.5 percentage points higher wage growth experienced by fixed-term workers with 6-months contracts able to keep their jobs beyond their initial contract period. Given the limited number of short-term temporary workers in those circumstances, the overall wage gap between past fixed-term and indefinite-term workers is unlikely to vanish in the near future.     

The pervasive absence of compensating differentials

We study the relation between individual preferences for job amenities (e.g., type of work, job security) and compensating wage differentials in cross‐section. To this end, we estimate a partial equilibrium job search model on panel data from eight European countries. There are five non‐wage job characteristics and two sources of job‐to‐job mobility: on‐the‐job search and reallocation shocks. We also allow for two types of unobserved heterogeneity. We find strong preferences for amenities, especially job security, yet, these preferences do not translate into significant wage differentials in cross‐section. Counterfactual experiments show that one would need extremely low levels of search frictions for compensating differentials to arise. Lastly, a similar exercise on the distribution of job change outcomes reveals the role of constrained job‐to‐job mobility in the absence of compensating wage differentials.

The Gender Wage Gap in Europe: Job Preferences,Gender Convergence and Distributional Effects

The gender wage gap has declined over time. However, most of the remaining gap is unexplained, partly because of gender convergence in wage‐determining characteristics. In this paper, we show the degree of convergence differs substantially across Europe. In some countries, predominantly in Eastern Europe, the gender wage gap is entirely unexplained. However, in other countries, differences between the characteristics of men and women explain a relatively large proportion of the wage gap. Gender differences in job preferences contribute 10% to the wage gap, which is more than job tenure, previous employment status or field of study. The role of job preferences is particularly strong at the top of the wage distribution.     

Immigrant wage profiles within and between establishments

Life cycle wages of immigrants from developing countries fall short of catching up with wages of natives. Using linked employer–employee data, we show that 40% of the native–immigrant wage gap is explained by differential sorting across establishments. We find that returns to experience and seniority are similar for immigrant and native workers, but that differences in job mobility and intermittent spells of unemployment are major sources of disparity in lifetime wage growth. The inferior wage growth of immigrants primarily results from failure to advance to higher paying establishments over time. These empirical patterns are consistent with signaling disadvantages of immigrant job seekers, but not with the explanation that low wage growth follows from inferior information about employers and job opportunities.     

MEASURING HUMAN CAPITAL AND ITS EFFECTS ON WAGE GROWTH

Abstract Ever since Mincer, years of labour market experience were used to approximate individual's general human capital, while years of seniority were used to approximate job‐specific human capital. This specification is restrictive because it assumes that starting wages at a new job depend only on job market experience. In this paper, I investigate the effects of human capital on wage growth by using a more flexible specification of the wage equation, which allows for a rich set of information on past employment spells to affect the starting wages. In addition, I endogenize the labour mobility decision. In order to illuminate the effects of human capital accumulation patterns on wage growth, I compare counterfactual career paths for representative individuals.     

A model of labour supply with job offer restrictions

We specify a model of labour supply with job offer restrictions. A job offer is defined by a wage rate and working hours. The number of job offers is restricted, and follows a Poisson distribution. Individuals choose the alternative with the highest utility level. Three specifications are estimated: a basic specification, a specification in which the number of job offers depends on characteristics, and a specification in which the wage rate depends on working hours. Although the properties of the sample distribution of hours observed are replicated well for all of the specifications, the implications for the underlying behaviour are different.     

Job security and employee well-being: Evidence from matched survey and register data

We examine the effects of establishment- and industry-level labor market turnover on employees' well-being. The linked employer-employee panel data contain both survey information on employees' subjective well-being and comprehensive register-based information on job and worker flows. We test for the existence of compensating wage differentials by explaining wages and job satisfaction with average uncertainties, measured by an indicator for a high excessive turnover (churning) rate. The results are consistent with the theory of compensating wage differentials, since high uncertainty increases real wages, but high uncertainty has no effect on job satisfaction while not controlling for wages.     

How do workers decide their jobs? The influence of income,wage and job characteristics

This paper provides results on the economic decision‐making process of Spanish workers, who decide their jobs from the effects of variations in the non‐wage income, the wage and the prices of non‐pecuniary job characteristics. To that end, we formulate a non‐separable generalization of the Linear Expenditure System (NLES) as a joint model of labor supply and job characteristics demand, estimated separately for both males and females, using a 1991 Spanish survey. The main results show that: (i) some job characteristics have a positive effect on the wage, whereas others have a negative effect; (ii) the average percentage effect of employer size and the complexity index are higher for males than for females, with the fatal accident risk displaying similar values; (iii) if the non‐wage income of every worker increases, these individuals will prefer to devote less hours to work, and will also prefer jobs in smaller companies and with a lower risk; and (iv) if the wage and hedonic prices of non‐pecuniary job characteristics increase, then both males and females will prefer to reduce their labor supply, and devote their available time to jobs in bigger firms, with a higher risk and complexity.

Are there pecuniary compensations for working conditions?

In this paper we assess the relative contribution of working conditions to wage determination with an emphasis on differences along the earnings distribution. A survey of British employees in 2001 rich in questions regarding the job post enables us to separate the contribution of working conditions, job attributes and individual characteristics to the process of wage determination. Standard wage equations reveal that covariates such as having “repetitive job” and using generic skills such as “literacy” or “customer handling skills” are associated with significant premiums and penalties. Quantile regressions confirm the presence of penalties to poor working conditions, such as “working to tight deadlines”, that are significant in the middle section of the earnings distribution and robust to the inclusion of a wide range of controls for person, firm and other job characteristics. Counterfactual decompositions at quantiles show that, despite the apparent penalty, there are pecuniary compensations to poor working conditions around the first quartile and the median of the earnings distribution.     

From the dark end of the street to the bright side of the road? The wage returns to migration in Britain

We examine the impact of internal migration in Britain on the growth in men's hourly wages using nationally representative panel data. To do this we compare wage outcomes for migrants against different control groups, and explicitly allow for the potential endogeneity of the migration decision. Our results demonstrate the existence of a wage growth premium to migration. The size of this premium depends on any associated job mobility and the reason for migration, and is largest for continuously employed men who migrated for job related reasons. The wage profiles of migrants and other workers diverge substantially in the two years post-migration.     

The Turnover‐Reducing Effects of the Minimum Wage may Harm the Economy

This article surveys the literature on the effects of the minimum wage and argues that the observed reduction in turnover rates is not necessarily desirable. If a curvilinear relationship exists between firm productivity and turnover, the effects of the minimum wage on reducing turnover may create a distance between the actual turnover rate and the optimal rate. Consequently, even if we accept the proposition that minimum wages have little impact on employment, they may reduce productivity or job growth in sectors not directly affected by the minimum wage.     

Bargaining and Wage Rigidity in a Matching Model for the US

This paper uses robust econometric methods to assess previous empirical results for the Mortensen and Pissarides ( 1994 ) matching model. Assuming all wages are negotiated each period is inconsistent with the history dependence in US wages, even allowing for heterogeneous match productivities, time to build vacancies and credible bargaining. Flexible wages for job changers, with rigid wages for job stayers, allows the model to capture this history dependence and is not inconsistent with parameter calibrations in the literature. Such wage rigidity affects only the timing of wage payments over the duration of matches; conclusions about other characteristics are unaffected by it.     

Inter‐industry Wage Differences and Individual Heterogeneity*

Two well‐established findings are apparent in the analyses of individual wage determination: cross‐section wage equations can account for less than half of the variance in earnings and there are large and persistent inter‐industry wage differentials. We explore these two empirical regularities using longitudinal data from the British Household Panel Survey (BHPS). We show that around 90% of the variation in earnings can be explained by observed and unobserved individual characteristics. However, small – but statistically significant – industry wage premia do remain, and there is also a role for a rich set of job and workplace controls.     

The interrelated dynamics of unemployment and low‐wage employment

This paper examines the extent of state dependence in unemployment and the role played in this by intervening low‐wage employment. A range of dynamic random and fixed‐effects estimators are compared. Low‐wage employment is found to have almost as large an adverse effect as unemployment on future prospects and the difference in their effects is found to be insignificant. Evidence is presented that low‐wage jobs act as the main conduit for repeat unemployment and considerably increases its probability. Obtaining a higher‐wage job reduces the increased risk of repeat unemployment to insignificance. Copyright © 2007 John Wiley & Sons, Ltd.     

Job mobility and the gender wage gap in Italy

This paper investigates the contribution of gender differences in job mobility to the emergence of a gender wage gap in the Italian labour market. We show that over the first 10 years of labour market experience job mobility accounts for up to 30% of total log wage growth for men and only 8.3% for women, and that this difference is mainly due to differences in returns to mobility. The gender mobility gap is robust to the inclusion of individual, job and firm characteristics, to different ways of accounting for individual unobserved heterogeneity, and is mainly found for voluntary job moves. Looking at the characteristics of the jobs and the firms' workers move to, we find that moves to larger firms represent by far the main source of gender differences in returns to mobility. We offer two possible explanations for this finding; one which involves differences in bargaining behaviour and one which relates to the theory of compensating differentials.     

Wages,implicit contracts,and the business cycle: Evidence from a European panel

We study the joint behavior of hours and wages over the business cycle in a unique panel of 13 European countries, and document significant history dependence in wages. Workers who experience favorable market conditions during their tenure on the job have higher wages, and work fewer labor hours. Unobserved differences in productivity, such as varying job quality, or match-specific productivity are not likely to explain this variation. The results instead point to the importance of contractual arrangements in wage determination. In economies with decentralized bargaining practices, such arrangements resemble self-enforcing insurance contracts with one-sided commitment (by the employer). On the other hand, in countries with strong unions and centralized wage bargaining, wage behavior is better approximated by full-commitment insurance contracts. The co-movement of hours and wages further confirms a contractual framework with variable worker hours. Despite the strong prevalence of contracts in Europe, however, the elasticity of labor supply is considerably smaller compared to the U.S. labor market.     

Unemployment and compensating wages: an analysis of shift work

Compensating wages have been documented for a number of job attributes including working non-standard hours. Using data that aggregates across occupations, our analysis confirms a wage premium for working night shifts. However, the compensating wage is greater in areas where unemployment is low, suggesting that employers are less pressured to compensate for night shifts when employment opportunities are relatively scarce. If this result holds for other undesirable work characteristics, such as risk of death on the job, then weak labor markets will have lower compensating wages in general.     

Wage changes through job mobility in Europe: A multinomial endogenous switching approach

This paper presents evidence on the relationship between job mobility and wage mobility for various European countries using the European Community Household Panel (1994–2001). While much of the earlier research uses least-squares regression to predict wages for individuals with different labour market experience, we have found that it is important to take into account the possible non-random selection between job movers and stayers and between voluntary and involuntary movers. In this paper we focus on the effects of an unemployment spell on subsequent wages by estimating a multinomial endogenous switching model composed of two selection equations and three wage equations. Our results indicate that job mobility through unemployment has negative returns in all the analysed economies. As regards stayers, these losses range from 8% in Portugal to 21% in Germany while losses with respect to voluntary movers vary from 14% in Spain to 31% in Portugal.
