Intermittent work activity and earnings

Patterns of intermittent work activity appear to be more common in the modern labour market, at least for younger workers. This study extends earlier models of the relationship between labour market intermittency and earnings to include both part time work and nonparticipation, to differentiate between past work experience and current job tenure, to allow for nonlinear experience effects, and to account for selection bias arising from the exclusion of nonworkers. The results suggest that the effects of part time work and nonparticipation on earnings are similar. Moreover, some common patterns emerge: the effects are larger for women, greater for young workers, and greater when intermittency replaces current job tenure.     

A longitudinal analysis of earnings change in Canada

Abstract.  We use tax‐based longitudinal microdata for 1982–99 to (i) examine how earnings distributions have shifted, (ii) identify changes in earnings mobility patterns, and (iii) replicate and update Beaudry and Green's cohort analysis of age‐earnings profiles. We find: (i) increased polarization of men's earnings and marked decline in real earnings of workers aged 20–4; (ii) general decline in men's earnings mobility, while women's mobility has increased for young and prime‐age workers; and (iii) upward drift in earnings profiles of 1960s–1970s entry cohorts and downward shifts for 1980s–1990s cohorts (largely confirming Beaudry and Green's findings), but suggestive of steepening profiles for the 1990s cohorts.

Changing income inequality: A distributional paradigm for Canada

This paper examines the major changes in income inequality in Canada since the 1970s and collects them as a distributional paradigm for Canada. It focuses on labour market changes in terms of shares of workers and earnings shares for lower earners, middle‐class workers and higher earners in a flexible general framework. Polarization of full‐time workers, loss of middle‐class earnings share and increase in a higher earnings gap are highlighted. Changing returns to human capital, role of demographics and cohort effects and declining labour share are examined. The paper also reviews evidence of changing economic mobility and estimating the role of inequality of opportunity.     

The Effects of Marginal Employment on Subsequent Labour Market Outcomes

Abstract. Unemployed workers in Austria do not lose their unemployment benefits (UI) if they work in a job where their earnings are below a certain threshold [‘marginal employment’ (ME)]. ME might improve their labour market status by signalling effort, or worsen it through reduced job‐search effort. Those who work in ME while claiming UI have less employment and lower earnings afterwards than those who do not. The penalty lessens over time but is still present after three years.     

Central Government versus private sector wages and cognitive skills: evidence using endogenous switching regression

The importance of estimation techniques that allow for nonrandom selection of workers into the public and private sectors has been established in the theoretical and empirical literature. A separate body of work has explored the contribution of cognitive and other basic skills to earnings. This article brings together these two strands of empirical literature using Adult Literacy and Lifeskills (ALL) survey data for Norway and Bermuda. In the case of Norway, results from both Ordinary Least Squares (OLS) and a switching regression model agree that cognitive skills are rewarded more in the public sector and that, in both sectors, the main effect is the direct effect of skills on earnings. In the case of Bermuda, however, switching regression estimates are substantially different with respect to the how skills affect earnings; furthermore, controlling for cognitive skills changes the nature of selection and, hence, the estimates of sector wage differentials.     

WAGE SIGNALING: A DYNAMIC MODEL OF INTRAFIRM BARGAINING AND ASYMMETRIC LEARNING*

The article analyzes the effect of employer–worker bargaining on wage dynamics in the presence of asymmetric information between current and potential employers. A failure to reach an agreement leads to output loss. Because the disagreement points depend upon the worker's productivity, productive workers separate themselves from less productive workers and signal their ability through wages. In existing models of asymmetric learning, wages are attached to publicly observable characteristics and wage growth occurs only when there is a change in observable characteristics. This model, in contrast, generates an increase in earnings dispersion in cohorts of workers with similar observable characteristics.     

Understanding the wage patterns of Canadian less skilled workers: the role of implicit contracts

Abstract .  We examine the wage patterns of Canadian less skilled male workers over the last quarter-century by organizing workers into job entry cohorts. We find entry wages for successive cohorts declined until 1997 and then began to recover. Wage profiles steepened for cohorts entering after 1997, but not for cohorts entering in the 1980s – a period when start wages were relatively high. We argue that these patterns are consistent with a model of implicit contracts with recontracting in which a worker's current wage is determined by the best labour market conditions experienced during the current job spell.     

Computer adoption and returns in transition

Across nine transition economies, it is the young, educated, English‐speaking workers with the best access to local telecommunications infrastructures who work with computers. These workers earn about 25 percent more than do workers of comparable observable skills who do not use computers. Controlling for likely simultaneity between computer use at work and labour market earnings makes the apparent returns to computer use disappear. These results are corroborated using Russian longitudinal data on earnings and computer use on the job. High costs of computer use in transition economies suppress wages that firms can pay to their workers who use computers.     

Low level equilibrium trap,unemployment, efficiency of education system,child labour and human capital formation

This paper builds an overlapping generations household economy model to examine the impact of adult unemployment on the human capital formation of a child and on child labour, as viewed through the lens of the adult’s expectations of future employability. The model indicates that the higher the adult unemployment rate in the skilled sector, the lesser is the time allocated by an unskilled adult towards schooling of her child. We also find that an increase in the unskilled adult’s wage may or may not decrease child labour in the presence of unemployment. The model predicts that an increase in child wage increases schooling and human capital growth rate only if the adults in the unskilled sector earn less than subsistence consumption expenditure. As the responsiveness of skilled wage to human capital increases, schooling and human capital growth rates increase. The model dynamics bring out the importance of education efficiency and parental human capital in human capital formation of the child. In the case of an inefficient education system, generations will be trapped into low level equilibrium. Only in the presence of an efficient education system, steady growth of human capital is possible. Suitable policies that may be framed to escape the child labour trap are discussed as well.     

The Intriguing Relation Between Adult Minimum Wage and Child Labour

Because most parents send their children to work when compelled by poverty, one would expect a rise in adult wage to lower child labour. However, if the rise in wage is achieved by a minimum wage law, its impact can be intriguing. It can, for instance, cause some adults to be unemployed and send their children to work, which in turn displaces more adult labour and sends more children to work. The paper solves this process and predicts the incidence of child labour. It shows that, for appropriate parametric configurations, child labour may fall or rise as the adult minimum wage is raised.     

Evolution of the gender earnings gap among Canadian university graduates

This paper reports the results of an empirical analysis of the gender earnings gap among recent Canadian Bachelor's level university graduates. The overall gap as of two years leaving university narrowed significantly across successive cohorts of graduates, but widened significantly from two to five years out for all groups. Differences in the explanatory variables ‘explain’ account for between 40% and essentially the entire gap across the different periods, this portion rising from two to five years out and across cohorts. By the final group, all of the gap is thus ‘explained’ at the two-year point in time, and most of it is explained at the five-year mark, meaning that labour market returns (measured in this manner) are largely gender-neutral for the last group of graduates. Hours of work is the single most important influence, while past work experience, job characteristics, family status, and province of residence and language have smaller and more mixed effects.     

Earnings Instability and Tenure

We study the effect of tenure on earnings instability in Italy using the reforms of temporary employment contracts, which affected the average tenure of workers differentially across cohorts. We develop a model of earnings dynamics, and we exploit the variation of tenure and instability over time and across birth cohorts to estimate policy‐relevant parameters. Our results indicate that each year of tenure on the job reduces earnings instability by 11 percent; the drop is faster in the first three years of the match. Workers on a temporary contract have an earnings instability up to 100 percent higher than workers on a permanent contract.     

Screening and Human Capital in the Australian Labour Market of the 1990s

This paper presents tests of the screening hypothesis using data on adult males from the 1996 Australian Census of Population and Housing. These tests are based on comparisons of wage and salary earners and the self-employed, and public and private sector workers, as examples of screened and unscreened employments. The first test compares the mean levels of schooling, income and labour market experience in screened and unscreened sectors, while the second examines the returns to schooling and the goodness of fit of the earnings models for both wage and salary earning (separated into public and private sector employees) and self-employed groups. The results are equivocal, but suggest screening could be part of the earnings determination process in the Australian labour market.     

Trade union membership and earnings in Kenyan manufacturing firms

This study analyses the effect of trade unions on male earnings in the Kenyan manufacturing sector using a regression method, which takes into account endogeneity of the union status of workers. In contrast to earlier studies of the Kenyan labour market that report a negative effect of unions on wages, a positive effect is found. The study further shows that elite workers tend to abstain from union membership.     

Career, experience and returns to human capital: is the dual labour market hypothesis relevant for the UK?

This paper investigates the relationship between career status, labour market experience and returns to human capital accumulation in the context of a two-tier, career and non-career labour market. Using micro data from the British Household Panel Survey (BHPS), this study detects wage and employment mechanisms that differ between these two tiers of workers. The paper finds no support for the hypothesis of strict duality, by which the returns to education are expected to differ across labour market segments, with the returns in career employment being high and positive and the returns in the non-career sector being close to zero. The paper, however, finds support for significant returns to current tenure only in the career sector and also for the scarring hypothesis, according to which part-time employment and unemployment experience have a negative effect on participation and earnings in the career sector. Finally, there is evidence that only non-career earnings are significantly affected by local demand conditions, in contrast to earnings in the career sector. Career status is modelled as an endogenous variable subject to an initial job choice.     

International students and labour market outcomes of US-born workers*

Do international students graduating from US colleges and universities affect labour market outcomes of similarly educated native-born workers? I address this question by exploiting a change in US visa policy that results in increases in the labour supply of master’s-level international students to the US labour market in science, technology, engineering and mathematics (STEM) fields. Estimates show that increases in their labour supply via temporary work permits in a certain field reduce employment of recently graduated native-born holders of a master’s degree but increase earnings of experienced native-born holders of a master’s degree in the same field. These findings support the hypothesis of substitution between skills of similarly educated immigrants and native-born individuals in the same age group and complementarity between skills of those in different age groups.     

Women’s investment in career and the household division of labour

This paper examines how partners in a couple share domestic work according to the woman’s investment in career. Investment is measured relatively to other women or to the partner. While previous studies mainly focused on the influence of wages and earnings, we extend them by considering more dimensions describing the intensity of the woman’s attachment to the labour market. We use the 2010 French Time Use survey to estimate a model of household division of labour in dual earner couples. We find that the more women are invested in career, the less domestic work they perform during weekdays, which is partly substituted by their partners but only on weekend days. The sharing of tasks is thus less unequal in those couples. However, women still spend more time than their partners on average performing domestic work, even when the woman outperforms him in career, implying no role reversal in the division of labour.     

The Effects of Health, Wealth, and Wages on Labour Supply and Retirement Behaviour

This paper estimates a life cycle model of labour supply, retirement, and savings behaviour in which future health status and wages are uncertain. Individuals face a fixed cost of work and cannot borrow against future labour, pension, or Social Security income. The method of simulated moments is used to match the life cycle profiles of labour force participation, hours worked, and assets that are estimated from the data to those that are generated by the model. The model establishes that the tax structure of the Social Security system and pensions are key determinants of the high observed job exit rates at ages 62 and 65. Removing the tax wedge embedded in the Social Security earnings test for individuals aged 65 and older would delay job exit by almost one year. By contrast, Social Security benefit levels, health, and borrowing constraints are less important determinants of job exit at older ages. For example, reducing Social Security benefits by 20% would cause workers to delay exit from the labour force by only three months.     

The evolution of wage inequality in Italy

This article analyses the evolution of inequality in yearly and daily wages between and within groups of blue and white collar, using the INPS-ISFOL database for the period 1985 to 1999 in Italy. Between-group inequality increased in the 1990s as clerical wages grew slowly, whereas blue collars' wages remained nearly constant. Within-group inequality increased only if measured by daily wages. The covariance structure analysis shows that inequality comes from persistent differentials among older workers and from high income volatility for younger cohorts. Within inequalities in office and manual workers are driven by the growth of permanency for the older cohorts (individual abilities, say experience, matter more) and by the growth of income volatility for the younger cohorts (luck in the labour market). Within each group, low paid workers during their career acquire earning gains for their abilities and reduce differentials with respect to high paid workers.
