Human Capital Spillovers within the Workplace: Evidence for Great Britain*

In this paper, we use a unique matched worker–workplace data set to estimate the effect on own earnings of co‐workers’ education. Our results, using the 1998 GB Workplace Employee Relations Survey, show significant effects. An independent, significantly positive effect from average workplace education is evident; own earnings premia from years of education fall only slightly when controlling for workplace education. This result suggests that the social returns to education are strongly positive – working with colleagues who each had 1.2 years (1 standard deviation) of more education than the average worker, boosts own earnings by 11.1%. An additional year of any single co‐worker's education is worth about 3.2% of an additional own year of education. We also test for interactions between own and co‐worker education levels and for ‘skills incompatibility’ when worker education levels are heterogeneous. The interactions appear negative: own education is not much valued at workplaces where co‐workers’ education levels are already high. There is no evidence that workplace heterogeneity in worker education levels adversely affects own earnings. This result runs counter to theoretical predictions, and suggests that workers compete in tournaments for high‐paying jobs.     

Long-run underperformance following private equity placements: The role of growth opportunities

Our results show that the post-offering performance of private equity issuers is related to growth opportunities. We find significant long-run underperformance in stock returns following private placements only for firms with high Tobin's q. High-q firms experience not only poor stock price performance but also poor operating performance. Low-q firms, in contrast, do not display significant stock price or operating underperformance. We further examine three potential explanations for this relation: over-investment in assets by managers, investor skewness preference, and over-optimism about earnings prospects. Our results are consistent with the view that investors are overly optimistic about the prospects of high growth firms.     

The incentive for working hard: explaining hours worked differences in the US and Germany

This paper seeks to explain the greater hours worked by Americans compared to Germans in terms of forward-looking labor supply responses to differences in earnings inequality between the countries. We argue that workers choose current hours of work to gain promotions and advance in the distribution of earnings. Since US earnings are more unequally distributed than German earnings, the same extra work pays off more in the US, generating more hours worked. Supporting this inequality–hours hypothesis, we show that in both countries hours worked is positively related to earnings inequality in cross-section occupational contrasts and that hours worked raises future wages and promotion prospects in longitudinal data.     

ATTITUDES TOWARDS ECONOMIC RISK AND THE GENDER PAY GAP

This paper examines the links between gender differences in attitudes towards economic risk and the gender pay gap. Consistent with the literature on the socio-economic determinants of attitudes towards economic risk, it shows that females are much more risk averse than males. It then extends this research to show that workers with more favorable attitudes towards risk are associated with higher earnings, and that gender differences in attitudes towards economic risk can account for a small, though important, part of the standardized gender pay gap.     

Language usage,participation, employment and earnings: Evidence for foreigners in West Germany with multiple sources of selection

Language proficiency may not only affect the earnings of the individual, but the probability to participate in the labor market or becoming employed as well. It may also affect selection of people into economic sector and occupation. In this paper, the effects of language proficiency on earnings are analyzed for foreigners in Germany with joint consideration of up to four types of selection. The results show that language proficiency significantly increases participation and employment probability and affects occupational choice. When selection into economic sector and occupation is regarded, we do not find an impact of language ability on earnings thereby implying an indirect effect.     

Occupational change,employer change,internal migration,and earnings

"In this paper I use microdata from the [U.S.] Panel Study of Income Dynamics to measure the financial returns to intercounty and interstate migration for individuals in a temporal framework accounting for gains that accrue over time....To account for the indirect effects of migration on earnings, explanatory variables are created by interacting migration status with: (1) occupational change, (2) employer change and (3) changes in both occupation and employer. These interaction terms are then included in the earnings functions. Earnings are estimated for three years subsequent to the migration decision to account for the financial returns to migration accruing over time. Results indicate that, when estimating earnings, the use of a simple migration dummy variable will mask the indirect effects of migration on earnings."     

Occupational and industrial mobility in the United States

Using the Panel Study of Income Dynamics, and using both the original and the new series of occupation and industry codes, we investigate occupational and industrial mobility of individuals over the 1969–1980 and 1981–1993 periods in the U.S. We find that workers changed both occupations and industries more frequently in the later period. We also find that for men occupational and industrial changes are associated with lower earnings, though this effect has lessened somewhat over time; while for women the results are mixed. Our results also indicate that older and better paid men are less likely to shift occupation or industry.     

Matching,Reallocation and Changes in Earnings Dispersion*

The ‘fractal’ nature of the rise in earnings dispersion is one of its key features. In this paper, we offer a new perspective on the causes of changes in earnings dispersion, focusing on the role of labour reallocation. We set out a framework showing that job and worker reallocation affects earnings dispersion. We quantify this using a data set comprising almost the universe of workers and employers in Maryland. The changing allocation of workers to jobs played a significant role in explaining movements in the dispersion of earnings.     

Performance pay, risk attitudes and job satisfaction

We present a model in which workers with greater ability and greater risk tolerance move into performance pay jobs to capture rents and contrast it with the classic agency model. Estimates from the German Socio-Economic Panel confirm testable implications drawn from our model. First, before controlling for earnings, workers in performance pay jobs have higher job satisfaction, a proxy for on-the-job utility. Second, after controlling for earnings, workers in jobs with performance pay have the same job satisfaction as those not in such jobs. Third, those workers in performance pay jobs who have greater risk tolerance routinely report greater job satisfaction. While these findings support models in which workers capture rent, they would not be suggested by the classic agency model.     

Estimating wage losses of displaced workers in Germany

This paper employs the German Socioeconomic Panel (GSOEP) and the social insurance file (IAB) to study the effect of displacement on reemployment earnings of West German workers. On average, wages of the displaced decline only slightly upon reemployment. For workers in the IAB sample in 1986, we find that the lowest earnings quartile, in which displacement is concentrated, even gains slightly (+2%), while wage growth losses for the upper three quartiles are comparable with US evidence (−17%). Large wage losses are persistent and associated with changes of industry, but not of firm. A surprising finding is that displacement in Germany is often associated with later recall, in contrast to the North American experience.     

Job hopping, earnings dynamics, and industrial agglomeration in the software publishing industry

This paper investigates the implications of industrial clustering for labor mobility and earnings dynamics in one large and increasingly important high-technology sector. Taking advantage of longitudinal employee-employer matched data, I exploit establishment-level variation in agglomeration to explore how clustering in the software publishing industry affects labor market outcomes. The results show that clustering makes it easier for workers to job hop within the sector. Higher earnings levels in more agglomerated areas are partly attributable to sorting across locations among workers and firms in the industry on the basis of observable and unobservable characteristics. Controlling for this heterogeneity, workers in clusters have relatively steep earnings-tenure profiles, accepting lower wages early in their careers in exchange for stronger earnings growth and higher wages later. These findings are consistent with theoretical models in which agglomeration improves labor market coordination and facilitates greater learning and human capital formation.     

The cyclicality of effective wages within employer-employee matches in a rigid labor market

This study analyzes real wage cyclicality for male full-time workers within employer-employee matches in Germany over the period 1984-2004. Five different wage measures are compared: the standard hourly wage rate; hourly wage earnings including overtime and bonus pay; the effective wage, which takes into account unpaid overtime; and monthly earnings, with and without additional pay. None of the hourly wage measures exhibits cyclicality except for the group of salaried workers with unpaid overtime. Their effective wages show a strongly procyclical reaction to changes in unemployment. Despite acyclical wage rates, salaried workers without unpaid overtime experienced procyclical earnings movements if they had income from extra pay. Monthly earnings were also procyclical for hourly paid workers with overtime pay. These findings suggest that cyclical earnings movements are generated by variable pay components, such as bonuses and overtime pay, and by flexible working hours. The degree of earnings procyclicality revealed for the German labor market is comparable to the United States.     

Consequences of self-employment for women and men in the United States

Many self-employed workers return to the wage and salaried sector of the labor market after some time. It is possible that the self-employment spell will lead to lower earnings or earnings growth upon return, due to depreciation of firm or sector-specific human capital. Using longitudinal data from the National Longitudinal Survey of Young Women (NLS), this paper examines the effects of spells of self-employment on the future wage and salary sector earnings of male and female workers in the United States. The results indicate substantial penalties arise for women, in terms of returns to experience, while there is little or no impact for men.

The effects of Wal-Mart on local labor markets

We estimate the effects of Wal-Mart stores on county-level retail employment and earnings, accounting for endogeneity of the location and timing of Wal-Mart openings that most likely biases the evidence against finding adverse effects of Wal-Mart stores. We address the endogeneity problem using a natural instrumental variables approach that arises from the geographic and time pattern of the opening of Wal-Mart stores, which slowly spread out from the first stores in Arkansas. The employment results indicate that a Wal-Mart store opening reduces county-level retail employment by about 150 workers, implying that each Wal-Mart worker replaces approximately 1.4 retail workers. This represents a 2.7 percent reduction in average retail employment. The payroll results indicate that Wal-Mart store openings lead to declines in county-level retail earnings of about $1.4 million, or 1.5 percent. Of course, these effects occurred against a backdrop of rising retail employment, and only imply lower retail employment growth than would have occurred absent the effects of Wal-Mart.     

Cross-sectional earnings risk and occupational sorting: The role of risk attitudes

This paper investigates to what extent individuals' risk preferences are correlated with the cross-sectional earnings risk of their occupation. We exploit data from the German Socio-Economic Panel, which contains a direct survey question about willingness to take risks that has been shown to be a behaviorally valid measure of risk aversion. As a measure of earnings risk, we use the cross-sectional variation in earnings that is left unexplained by human capital variables in Mincerian wage regressions. Our evidence shows that individuals with low willingness to take risks are more likely to work in occupations with low earnings risk. This pattern is found regardless of the level of occupation categories, region, gender and labor market experience.     

我国新业态从业人员职业伤害保险制度:模式选择与构建思路

现阶段应对新业态从业人员职业伤害风险的法律机制主要有工伤保险和商业保险两种模式,前者遵循无过失补偿原则,确保遭受职业伤害的劳动者可按照法定标准获得救济,但这种模式主要保障建立稳定劳动关系的劳动者群体。而商业保险遵循经济对等性原则,导致收入不稳定的新业态从业人员难以通过持续缴费来获得稳定保障。构建专门的新业态职业伤害保险制度尤为必要,但在制度构建过程中却面临着认识不统一、存在路径依赖等困境。未来的新业态职业伤害保险制度应与劳动关系脱钩,且需采取扩大覆盖人员范围、出台专门立法、建立职业伤害基金、优化缴费方式以及完善职业伤害认定规则等具体措施。     

TRADE UNIONS AND THE DISPERSION OF EARNINGS IN BRITISH ESTABLISHMENTS, 1980–90†

ABSTRACT The relationship between unions and earnings dispersion is examined using establishment-level data from the 1980, 1984 and 1990 Workplace Industrial Relations Surveys. Initially the cross-sectional relationship is examined using the 1990 data. The earnings dispersion of skilled and semiskilled workers is seen to be lower across unionized establishments than across non-union establishments; secondly, within-establishment earnings dispersion is lower in plants which recognize trade unions for collective bargaining purposes than in those that do not. All three surveys are then utilized to ascertain to what extent the decline in unionization in Britain has contributed to the rise in earnings inequality of semi-skilled workers. There was a sizeable and important widening of the gap in the dispersion of earnings across union and non-union plants between 1980 and 1990. For semi-skilled earnings, the decline in the share of plants with recognized unions can account for 11-17 percent of the rise in earnings inequality over this time period. The importance of falling union activity (as measured by union recognition) seemed to accelerate through the 1980s. Between 1980 and 1984 the relatively small falls in aggregate recognition explain less than 10 percent of the inequality increase, whereas between 1984 and 1990 about one-quarter of the increase can be accounted for by the fall in unionization. The majority of the rise in earnings inequality is, however, due to a large increase in earnings dispersion across non-union establishments.     

Informal employment and the earnings of home-based home care workers in the United States

Informal employment continues to exist in parallel with formal employment among the US home-based home care workers and undermines the workers' economic security. This study examines the extent to which the earnings of the US home-based home care workers are affected by informal employment arrangements and state labour policies designed to benefit low-wage home care workers. Using a sample of 1,318 home-based home care workers from the 2017 and 2018 Annual Social and Economic Supplement of the Current Population Survey, this study found that (i) informally employed home-based home care workers had a 9% reduction in annual earnings and that (ii) their earnings were not improved by generous state minimum wages and Domestic Workers' Bill of Rights while the earnings of agency employees were. The findings highlight the importance of strong enforcement of labour standards for informally employed home care workers in the United States.
