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.     

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.     

Collective Wage Contracts,Opt‐Out Clauses,and Firm Wage Differentials: Evidence from Linked Employer–Employee Data

Using a large linked employer–employee data set, this article studies whether the existence and use of flexibility provisions within centralized collective wage agreements alter the structure of pay across employers. Using level regressions and first‐difference methods, we find that—compared with contracts without any flexibility—wages under opt‐out clauses are more responsive to local profitability conditions in below‐average‐performing establishments. In contrast, the sensitivity of wages to local profitability is smaller in high‐performance establishments. Our results provide further evidence for a threat potential of the existence of opt‐out clauses whose impact on flexibility is larger than the real application.     

Rising Wage Inequality, Returns to Education and Labour Market Institutions: Evidence from Ireland

Institutional factors and increased supply of skilled labour have been advanced in an effort to explain why some countries have experienced smaller increases in earnings dispersion and in returns to education than the USA and the UK. Ireland has had a highly centralized wage bargaining structure and the supply of skilled labour has increased sharply in recent years; hence, relatively little change in earnings dispersion might be expected. We compare the distribution of earnings in Ireland in 1987 and 1994 and find a surprisingly large growth in earnings dispersion. In addition, using a decomposition technique, we find that much of this is accounted for by increasing returns to measured.     

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.     

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.     

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.     

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.     

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.     

Prevailing Wage Regulations and School Construction Costs: Cumulative Evidence from British Columbia

The effect of prevailing wage laws on the cost of public construction has been the subject of an ongoing public policy debate. We measure this effect by comparing the public/private construction cost differential for schools built before and after British Columbia's Skills Development and Fair Wage Policy. Regression results indicate that public schools were 40.5 percent more expensive to build prior to the policy. This differential was 40.1 percent after the policy's enforcement. However, this change is not statistically significant. Regression results also indicate a stable construction cost function over the policy period. These results indicate that the effect of fair wage requirements was not different from zero in terms of magnitude or statistical significance. Combining these results with the findings of our previous research provides a comprehensive view regarding the effect of the British Columbian prevailing wage policy on school construction. This body of research, utilizing a variety of statistical methods, provides consistent evidence indicating that a relatively strong prevailing wage policy was not associated with changes in the efficiency or productivity of construction that contributes to increased building costs.     

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 Structure of the Permanent Job Wage Premium: Evidence from Europe

Using individual longitudinal European Community Household Panel data for thirteen countries during 1995–2001 and fixed‐effects models, I find for men, the permanent job wage premium is higher for younger workers and those who were noncitizens or foreign born; for women, the premium is higher for young workers, short‐tenure workers, and those who were noncitizens or foreign born. Thus, the gain to permanent employment is higher for those with less experience in the domestic labor market.     

Output Pay and Ethnic Wage Differentials: Canadian Evidence

Using the Workplace and Employee Survey, we are the first to examine the association between payment method and ethnic wage differentials in Canada. Following earlier theory, we hypothesize that output pay tying earnings to productivity makes it more difficult for employers to discriminate. The empirical estimations show that non‐Europeans in Canada paid by time rates receive lower earnings than Europeans paid by time rates. Yet, non‐Europeans paid by output pay receive virtually identical earnings to their European counterparts.     

Mergers and product quality: Evidence from the airline industry

Retrospective studies of horizontal mergers have focused on their price effects, leaving the important question of how mergers affect product quality largely unanswered. This paper empirically investigates this issue for two recent airline mergers. Consistent with the theory that mergers facilitate coordination but diminish competitive pressure for quality improvement, we find that each merger is associated with a quality decrease (increase) in markets where the merging firms had (had no) pre-merger competition with each other, and the quality change can have a U-shaped relationship with pre-merger competition intensity. Consumer gains/losses associated with quality changes, which we monetize, are substantial.     

Flexible Wage Contracts,Temporary Jobs,and Firm Performance: Evidence From Italian Firms

This study focuses on the effects of decentralized wage schemes and temporary forms of employment on firm performance. The effect of monetary incentives on workers' effort and firm performance is a central topic in economics. According to the principal‐agent paradigm, firms (the principal) have to link employees' remuneration schemes to any verifiable indicator of performance to avoid opportunistic behavior. The empirical evidence shows that financial incentives have the potential to exert strong effects on indicators of firm performance, such as productivity and worker absenteeism, although the degree of effectiveness of such schemes varies significantly according to the institutional/economic context in which firms operate. From both a theoretical and empirical point of view, the prediction on the effects of temporary types of employment on effort and productivity is less neat. In light of these considerations, this study uses a sample of Italian firms to provide further empirical evidence on whether and to what extent performance‐related pay schemes and contract flexibility affect workers' effort (in terms of absenteeism) and, in turn, firm productivity. These effects are analyzed for different types of workers (white collar vs. blue collar), working in workplaces characterized by a different degree of uncertainty and risk and in firms operating in different economic and institutional settings. Our results show that wage flexibility has a significant effect on effort and then on firm's productivity and that white‐collar workers are more responsive to monetary incentives than blue‐collar workers. Moreover, the presence of a large share of temporary contracts, implying a lower dismissal probability for permanent workers and a deterioration of the working environment, appears to reduce workers' motivation and effort.     

Productivity and Wage Effects of Firm-Level Collective Agreements: Evidence from Belgian Linked Panel Data

How do firm-level collective agreements affect firm performance in a multi-level bargaining system? Using detailed Belgian-linked employer–employee panel data, our findings show that firm-level agreements increase both wage costs and labour productivity (with respect to sector-level agreements). Relying on approaches developed by Bartolucci and Hellerstein et al., they also indicate that firm-level agreements exert a stronger impact on wages than on productivity, so that profitability is hampered. However, this rent-sharing effect mostly holds in sectors where firms are more concentrated or less exposed to international competition. Firm agreements are thus mainly found to raise wages beyond labour productivity when the rents to be shared between workers and firms are relatively big. Overall, this suggests that firm-level agreements benefit both employers and employees — through higher productivity and wages — without being very detrimental to firms’ performance.     

Rising markups,common ownership,and technological capacities

This paper analyses the impact of common ownership on markups and innovation and adds to the discussion of the recently observed patterns of a long term rise in market power. Using a panel of European manufacturing firms from 2005 to 2016, we structurally infer markups and construct a measure of common ownership. We use a propensity score reweighting estimator to eliminate biases due to observational characteristics and find an increase of firm markups ranging up to 3.3% on average in industries with high technological spillovers after the first exposure to common ownership. For companies directly held by common institutional investors, we also measure a positive effect on citation-weighted patents of up to 9.6% in high-spillover industries on average. Both findings are consistent with recent theoretical findings in López and Vives (2019).     

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.     

Non‐Standard Time Wage Premiums and Employment Effects: Evidence from an Australian Natural Experiment

We examine the effect of increasing Sunday wage premiums on retail industry employment in Australia, exploiting a quasi‐experimental policy change across two neighbouring states. Using both aggregate and individual‐level data, we adopt a difference‐in‐difference regression framework to estimate the causal impact of the policy change on employment outcomes. We find no evidence of changes in the total number of employees, and no effect on hours per employee in the years following the policy implementation. However, there appeared to be a decline in hours per employee in the announcement year of the policy change. Overall, it appears that in an industry dominated by part‐time and casual employment, any adjustment to the new Sunday wage rates occurred principally through flexibility in hours, rather than in the number of employees.     

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.
