Estimating the Wage Premium of Collective Wage Contracts: Evidence from Longitudinal Linked Employer–Employee Data

Using a large‐scale linked employer–employee dataset from western Germany, this paper presents new evidence on the wage premium of collective bargaining contracts. In contrast to previous studies, we seek to assess the extent to which differences in wages between workers in covered and uncovered firms arise from the nonrandom selection of workers and firms into collective bargaining coverage. By measuring the relative wage changes of workers employed in firms that change contract status, we obtain estimates that depart considerably from previous results relying on cross‐sectional data. Results from analyzing separate transitions show that leaving industry‐level contracts is associated with subsequent wage losses. However, the results from a trend‐adjusted difference‐in‐difference approach indicate that particularly the transitions to no coverage appear to be associated with negative shocks. Overall, our findings provide no evidence of a “true” wage effect of leaving wage bargaining, once we account for differences in pretransition wage growth.     

The Wage Premium for Job Seniority During the 1980s and Early 1990s

In this article I use Panel Study of Income Dynamics (PSID) data to study whether the rewards for job tenure have fallen since the early 1980s. An upward-sloping seniority-wage profile is generally thought to be an important dimension of compensation during a career. However, recent interest in the incidence of layoffs and changes in the structure of firms gives rise to the possibility that employment contracts are less often being structured to reward tenure or that such contracts are more difficult to honor. Using a two-stage estimator to attempt to control unmeasured individual and job match effects on wages, I find some evidence that the wage premium paid to senior workers has declined moderately. However, I find that these results are mildly sensitive to alternative methods of handling the relatively noisy PSID tenure data.     

The Structure of the Wage Gap for Temporary Workers: Evidence from Australian Panel Data

This study uses panel data for Australia to estimate the wage differential between workers in temporary jobs and workers in permanent jobs. It is the first study to use unconditional quantile regression methods in combination with fixed effects to examine how this gap varies over the entire wage distribution. While the wages of fixed‐term contract workers are found to be similar to those of permanent workers, low‐paid casual workers experience a wage penalty and high‐paid casual workers a wage premium compared to their permanent counterparts. Temporary agency workers also usually receive a wage premium, which is particularly large for the most well paid.     

Rents and Quasi Rents in the Wage Structure: Evidence from Hostile Takeovers

We test whether industry-related variation in wage premium and slopes of wage profiles reflects payments of rents or quasi rents, taking our cue from the wealth-transfer hypothesis, which argues that hostile takeovers target such rents. If these wage structure characteristics reflect extramarginal payments, then hostile takeover attempts that sought to transfer wealth from workers to shareholders should have targeted firms with the highest wage premia or the steepest wage profiles. We find that the likelihood of being a hostile takeover target between 1979 and 1989 was generally unrelated to these industry-related characteristics of the wage structure.     

Matching and Inverse Propensity Weighting Estimates of the Union Wage Premium: Evidence from Canada, 1997–2014

I estimate the union wage premium for private‐sector workers using Canadian data from Statistics Canada's Labour Force Survey from 1997 to 2014, examining the trend and gender differences in the premium. I obtain my estimates using matching and inverse propensity weighting estimators, which form counterfactuals for union workers. These estimators create better covariate balance and can also be used to address the bias that arises from the log transformation of wages.     

Paradox Lost: The Disappearing Female Job Satisfaction Premium

Using the original data source of Clark, we show that over the last two decades the female satisfaction gap he documented has vanished. This reflects a strong secular decline in female job satisfaction. This decline happened both because younger women became less satisfied as they aged, and because new female workers entered with lower job satisfaction than their early 1990s peers. Decompositions make clear that the decline does not reflect changing job characteristics for women but rather their increasingly less favourable evaluation of job characteristics. These findings fit with the suggestion that women in the early 1990s had a gap between their labour market expectations and actual experience that has since closed and that the gender satisfaction gap has vanished as a consequence.     

Previous Marriage and the Lesbian Wage Premium

This paper provides insight into the wage gap between partnered lesbians and other groups of women. Using data from the 2000 Decennial Census, we find that wages of never-married lesbians are significantly higher than wages of previously married lesbians and other groups of women. Results indicate that controlling for previous marriage reduces the estimated lesbian wage premium by approximately 20 percent. Our research also reveals that wage patterns of previously married lesbians mirror those of cohabiting heterosexual women. Overall, our results are consistent with the notion that the lesbian wage premium is driven, in part, by differences in the labor-market commitment of lesbians and heterosexual women.     

The Wage Effects of Computer Use: Evidence from WERS 2004

Computers and ICT have changed the way we live and work. The latest Workplace Employment Relations Survey (WERS) 2004 provides a snapshot of how using ICT has revolutionized the workplace. Various studies have suggested that the use of a computer at work boosted earnings by as much as 20 per cent. Others suggest this reported impact is due to unobserved heterogeneity. Using excellent data from the WERS employer–employee matched sample, we compare ordinary least squares (OLS) estimates with those from alternative estimation methods and those which include controls for workplace and occupation interactions. We show that OLS estimates overstate the return to computer use but that including occupation and workplace controls, reduces the return to around 3 per cent. We explore the return on different IT skills and find a small return to the use of the ‘office IT function’ and the intensity of computer use as measured by the number of tasks a computer is used for.     

Unions,Wage Gaps,and Wage Dispersion: New Evidence from the Americas

Using a common methodology, the effects of unions on wage levels and wage dispersion are estimated for two neighboring countries, Bolivia and Chile, and for the United States. The analysis shows that unions have broadly similar effects on the wage distribution within these three economies. The findings suggest that the political economy of unions, coupled with market constraints on labor costs, produce commonality in union wage effects that transcend other economic and institutional differences.     

The Impact of the Entry of Biosimilars: Evidence from Europe

Biologics represent a substantial and growing share of the U.S. drug market. Traditional “small molecule” generics quickly erode the price and share of the branded product upon entry, however only a few biosimilars have been approved in the US since 2015, thereby largely preserving biologics from competition. We analyze European markets, which have had biosimilar competition since 2006. Using our own survey, we analyze how market features and public policies predict biosimilar entry, price, and penetration, finding significant heterogeneity across countries and products. Effective buyer institutions are associated with increased biosimilar penetration. Our estimates can inform ongoing policy discussions.     

The Role of Job Attributes in Understanding the Public-Private Wage Differential

This study uses a unique data set for Great Britain to investigate the impact of differences in job attributes on the public-private wage differential. The study reveals that (1) there are substantial differences in wage structure between the two sectors, particularly finding that the public-sector wage structure is less sensitive to differences in the attributes of jobs, and (2) differences in job attributes play in a major role in accounting for pay differences across sectors.     

Dissecting Between-Plant and Within-Plant Wage Dispersion: Evidence from Germany

Using rich linked employer–employee data for (West) Germany between 1996 and 2014, we conduct a decomposition analysis based on recentered influence function (RIF) regressions to analyze the relative contributions of various plant and worker characteristics to the rise in German wage dispersion. Moreover, we separately investigate the sources of between-plant and within-plant wage dispersion. We find that industry effects and the collective bargaining regime contribute the most to rising wage inequality. In the case of collective bargaining, both the decline in collective bargaining coverage and the increase in wage dispersion among the group of covered plants have played important roles.     

The Greek Public Sector Wage Premium before the Crisis: Size,Selection and Relative Valuation of Characteristics

We examine the Greek public–private wage differential before the debt crisis to evaluate the prospective impact of the recent public sector pay cuts. We find a large public premium which persists after controlling for individual and job characteristics. For men, much of this is accounted for by self‐selection into the sector that rewards better their characteristics, while for women it is largely driven by sectoral differences in returns. We attribute these effects to more egalitarian pay structures in the public sector and to demand problems in the private sector. The recent policy measures only partially change this situation, as wage deflation extends to the private sector, preserving public premia for the low paid.     

Job Lock: Evidence from a Regression Discontinuity Design

Employer‐provided health insurance may restrict job mobility, resulting in “job lock.” Previous research on job lock finds mixed results using several methodologies. We take a new approach to examine job lock by exploiting the discontinuity created at age 65 through the qualification for Medicare. Using a novel procedure for identifying age in months from matched monthly Current Population Survey data and a relatively unexplored administration measure of job mobility, we compare job mobility among male workers in the months just prior to turning age 65 to job mobility in the months just after turning age 65. We find no evidence that job mobility increases at the age 65 threshold when Medicare eligibility starts. We also do not find evidence that other factors such as retirement, reduction in hours worked, Social Security eligibility, pension eligibility, and sample changes confound the results on job mobility in the month individuals turn 65.     

Identifying Minimum Wage Effects: New Evidence from Monthly CPS Data

The appropriateness of including year effects in employment models has been a contentious issue in the minimum wage literature. Using monthly data from the 1979–2004 Current Population Surveys, I find consistent evidence of adverse labor demand effects for teenagers across specifications preferred by those on each side of this debate. Estimated employment elasticities range from –0.2 to –0.3 and unconditional hours elasticities from –0.4 to –0.5.     

Wage councils,product markups and wage markdowns: Evidence from Uruguay

In 2005, after a leftist coalition won the national election for the first time, Uruguay returned to sector-level wage bargaining councils with active government participation. We estimate product markups and wage markdowns using firm-level data for the period 2002–2016, and report decreasing wage markdowns and increasing -to a lesser extent- firm-level product markups. We find statistically significant impacts of minimum mandated wages on product markups and wage markdowns, and additional effects of unions on wage markdowns. The evidence suggests that firms operate in monopsonistic labor markets. Though their bargaining power in the labor market was reduced over time as a result of wage councils, firms were able to pass a sizable part of the increases in labor costs to consumers.     

Interindustry Wage Differentials and Unobserved Ability: Siblings Evidence from Five Countries

We examine the role of unobserved ability in explaining interindustry wage differentials. By using data on brothers, we account for unmeasured abilities shared by siblings. The data came from four Nordic countries and the United States. In the Nordic countries, only a moderate proportion of the variability in industry wages can be attributed to unobserved ability, while unmeasured factors explain as much as half of the U.S. industry‐wage variation. Accounting for such differences, we show that the U.S. interindustry wage dispersion is similar with that in the Nordic countries.     

Institutional and Market Determinants of Wage Spillovers: Evidence from UAW Pattern Bargaining

Empirical wage spillovers are often observed, but their theoretical explanation is controversial because they are consistent with institutional wage comparisons stemming from fairness or union politics, but also with neoclassical alternative wages or correlated labor demand shocks. The nature of wage spillovers is analyzed using a data set of United Automobile, Aerospace, and Agricultural Implement Workers of America (UAW) wage settlements. The results support the hypothesis that institutional wage spillovers augment neoclassical economic forces in determining wages, albeit with some weakening after 1980.
