Computer Use,Job Tasks and the Part‐Time Pay Penalty

Using data from the UK Skills Surveys 1997–2012, we show that the part‐time pay penalty (PTPP) for women within low‐ and medium‐skilled occupations has decreased significantly. The convergence in computer use and non‐routine job tasks between part‐time and full‐time workers explains a large share of the decrease in the PTPP. This convergence took place mainly within occupations, and was not driven by changes in occupational segregation between the two groups of workers. The lower PTPP is also related to changes in the returns to job tasks. Relative changes in the importance of and returns to computer use and job tasks together explain more than 50 per cent of the decrease in the PTPP.     

The Effects of Minimum Wages on Low‐Skilled Immigrants’ Wages,Employment, and Poverty

Raising the minimum wage has been advanced as complementary policy to comprehensive immigration reform to improve low‐skilled immigrants’ economic well‐being. While adverse labor demand effects could undermine this goal, existing studies do not detect evidence of negative employment effects. We re‐investigate this question using data from the 1994 to 2016 Current Population Survey and conclude that minimum wage increases reduced employment of less‐educated Hispanic immigrants, with estimated elasticities of around –0.1. However, we also find that the wage and employment effects of minimum wages on low‐skilled immigrants diminished over the last decade. This finding is consistent with more restrictive state immigration policies and the Great Recession inducing outmigration of low‐skilled immigrants, as well as immigrants moving into the informal sector. Finally, our results show that raising the minimum wage is an ineffective policy tool for reducing poverty among immigrants.     

Task‐based structures in open source software: revisiting the onion model

Studies on Open Source Software (OSS) developer communities have long stated that there is a relationship between community structure and tasks carried out by project members. This relationship has been exemplified by the onion model, which has been instrumental in understanding self‐coordination in OSS projects. Despite its ubiquity, there is a lack of empirical evidence to validate the relative position of each task cluster within the onion model. In this study, we map out the community structure of a large open source project and observe its bug‐fixing patterns to explore the relationship between tasks and structure. Our study makes three significant contributions. First, we find no empirical evidence to support the structural location of bug‐fixing tasks in the onion structure. Second, we find empirical evidence to support the core‐periphery continuum model linking an actor’s coreness to problem‐solving ability. Third, our results suggest that the importance and location of each task within the core‐periphery structure evolve over time. These findings add clarity to the community structure and their implications for the management and coordination of collaborative innovation projects.

Skilled Immigration,Innovation, and the Wages of Native‐Born Americans

The paper examines the effects of skilled immigration on wages that can be credited to immigrants’ contribution to innovation. Using both individual and state‐level datasets from the United States, we find a significant and positive effect of immigration on wages that is attributable to skilled immigrants’ contribution to innovation. Our results confirm previous findings that immigrants contribute substantially to the host economy's innovation, which is a major driver of technological progress and productivity growth. When we augment the analysis to an immigration–innovation–wages nexus, the results suggest that as the share of skilled immigrants in a particular skill group increases, the wages of both natives and immigrants in that group also get a positive boost. We also identify evidence in favor of a positive spillover effect of skilled immigrants on a state's wage level of all workers, including those who do not directly contribute to innovation.     

Wage Dispersion and Firm Productivity in Different Working Environments

This article investigates the impact of wage dispersion on firm productivity in different working environments. More precisely, it examines the interaction with: (i) the skills of the workforce, using a more appropriate indicator than the standard distinction between white‐ and blue‐collar workers, and (ii) the uncertainty of the firm economic environment, which has, to our knowledge, never been explored on an empirical basis. Using detailed cross‐sectional linked employer–employee data for Belgium, we find a hump‐shaped relationship between (conditional) wage dispersion and firm productivity. This result suggests that up to (beyond) a certain level of wage dispersion, the incentive effects of ‘tournaments’ dominate (are dominated by) ‘fairness’ and/or ‘sabotage’ considerations. Findings also show that the intensity of the relationship is stronger for highly skilled workers and in more stable environments. This might be explained by the fact that monitoring costs and production–effort elasticity are greater for highly skilled workers, and that in the presence of high uncertainty, workers have less control over their effort–output relation, and associate higher uncertainty with more unfair environments.     

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.     

Immigration and Informal Labor

We develop state‐level proxies for informal employment using differences between measures of self‐reported employment and officially sanctioned employment. In construction and landscaping, industries associated with under‐the‐table labor, we develop proxies for informal work based on productivity per officially sanctioned worker. We relate each set of proxies for informal employment to changes in immigrant population and composition. We find some evidence that immigration is associated with informal employment generally and in the construction industry when prevailing wages are low. States with high concentrations of low‐skilled male immigrants have higher levels of informal employment in the landscaping industry.     

The Structure of Hiring Costs in Germany: Evidence from Firm‐Level Data

This paper analyzes the structure of hiring costs of skilled workers in Germany. Using detailed and representative firm‐level data on recruitment and adaptation costs of new hires, we find that average hiring costs amount to more than 8 weeks of wage payments (€4700). The structure of hiring costs is convex, as an increase in the number of hires by 1 percent increases hiring costs by 1.3 percent. We find moderate effects of labor market institutions on the magnitude but none on the structure of hiring costs. Furthermore, we provide evidence in favor of monopsony power in the German labor market.     

Impact of contract farming on land productivity and income of maize and potato growers in Pakistan

While the positive income effect of contract farming is well established in the literature, the heterogeneity of effects for different crops has not been widely investigated. This study compares the income and productivity effects of large-scale contract farming under contract schemes for potatoes and maize in Pakistan. In the area of the study, maize is a common staple crop, widely available in the market, while the potatoes produced by contract farmers are a special variety not sold in the market. We find that potato contracting is associated with significantly higher income for participating farmers, while maize contracting has no association with either income or productivity. We found no negative association between contract participation and income from other sources. Taken together, these results show a higher total household income for potato contract farmers. We also show unique evidence that potato contract farmers tend to employ more skilled workers under a salary system for the management of farms, which implies that contract farming may have positive spillover effects in the skilled labor market. Neither scheme, however, is associated with larger employment of agricultural labor for simple tasks.     

Minimum Cash Wages,Tipped Restaurant Workers,and Poverty

This is the first study to examine the effect of increases in the tipped minimum cash wage—the wage employers must pay to tipped employees—on poverty. Using March Current Population Survey data (1988–2014), we find that tipped minimum cash wage increases are associated with declines in the risk of a tipped restaurant worker living in a poor family (elasticities around –0.2). However, we find little evidence of poverty‐alleviating effects when using the household rather than the family as the sharing unit. This result is consistent with evidence that a substantial share of tipped workers who live in a poor family live in a nonpoor household with persons unrelated by blood, marriage, or adoption who contribute to the household's income. Furthermore, we find that tipped minimum cash wage hikes are associated with increases in the risk of a younger, less‐educated individual living in a poor family or household. Adverse labor demand effects that redistribute income among low‐skilled individuals drive these results. We conclude that raising the tipped minimum cash wage is a poorly targeted policy to deliver income to poor restaurant workers.     

Job Mobility in Europe,Japan and the United States

Evidence about job mobility outside the United States is scarce and difficult to compare cross‐nationally because of non‐uniform data. We document job mobility patterns of college graduates in their first three years in the labour market, using unique uniform data covering 11 European countries and Japan. Using the National Longitudinal Survey of Youth, we replicate the information in this survey to compare the results with the United States. We find that (a) US graduates hold more jobs than European graduates, (b) contrasting conventional wisdom, job mobility in Japan is only somewhat lower than the European average, and (c) there are large differences in job mobility within Europe.     

Long‐Run Patterns of Labour Market Polarization: Evidence from German Micro Data

The past four decades have witnessed dramatic changes in the structure of employment. In particular, the rapid increase in computational power has led to large‐scale reductions in employment in jobs that can be described as intensive in routine tasks. These jobs have been shown to be concentrated in middle‐skill occupations. A large literature on labour market polarization characterizes and measures these processes at an aggregate level. However, to date, there is little information regarding the individual worker adjustment processes related to routine‐biased technological change. Using an administrative panel dataset for Germany, we follow workers over an extended period of time and provide evidence of both the short‐term adjustment process and medium‐run effects of routine task‐intensive job loss at an individual level. We initially demonstrate a marked, and steady, shift in employment away from routine, middle‐skill, occupations. In subsequent analysis, we demonstrate how exposure to jobs with higher routine task content is associated with a reduced likelihood of being in employment in both the short term (after one year) and medium term (five years). This employment penalty to routineness of work has increased over the past four decades. More generally, we demonstrate that routine task work is associated with reduced job stability and more likelihood of experiencing periods of unemployment. However, these negative effects of routine work appear to be concentrated in increased employment to employment, and employment to unemployment transitions rather than longer periods of unemployment.     

Are family‐friendly workplace practices a valuable firm resource?

We study the determinants and consequences of family‐friendly workplace practices (FFWP) using a sample of over 450 manufacturing firms in Germany, France, U.K., and U.S. We find a positive correlation between firm productivity and FFWP. This association disappears, however, once we control for a measure of the quality of management practices. We further find that firms with a higher proportion of female managers and more skilled workers, as well as well‐managed firms, tend to implement more FFWP. Conversely, a firm's environment does not have a significant impact on the FFWP it provides. © 2010 The Authors. Strategic Management Journal published by John Wiley & Sons, Ltd.

High Performance Work Systems and Employee Experience of Work in the Service Sector: The Case of Aged Care

In spite of the growing body of research on high performance work systems (HPWS), there is little evidence on their application in the service sector. It is commonly argued, however, that occupational segmentation in services is a barrier to HPWS. Analysis of data from aged‐care workers indicates that: HPWS have positive outcomes for workers; highly skilled nurses are no more likely than lowly skilled personal care workers to be subject to HPWS; and in some cases, HPWS are associated with more positive outcomes for low‐skilled than high‐skilled workers. These findings suggest that HPWS may well be widely applicable in service settings.     

Transitions into Permanent Employment in Spain: An Empirical Analysis for Young Workers

This article analyses the transitions into permanent employment of a sample of young temporary employees in Spain for the period 1996–2003. For this purpose, we apply multiple‐spell duration techniques to a longitudinal dataset of temporary workers obtained from Social Security registers. Our main findings are as follows. First, the transitions from a temporary contract into unemployment and into another temporary contract are very high when compared with transitions into permanent employment. Second, the entry into permanent employment — although slightly increasing with tenure at the temporary contract — is very low; the only exception is that of semi‐skilled and unskilled individuals, who are particularly likely to enter into permanent employment at the 24th and the 36th month of tenure (respectively). Third, we find that there exists a substantial proportion of workers with unobservable characteristics that make them show high exit rates from temporary employment and, at the same time, a rapid exit from unemployment — while the remaining individuals exit from unemployment more slowly, particularly those who are receiving unemployment benefits.     

Is There a Wage Payoff to Innovative Work Practices?

During the 1980s, wage inequality increased dramatically, and the economy lost many high-wage jobs that had provided middle-class incomes to less skilled workers, increasingly restricting these workers to low-wage jobs lacking union or other institutional protections. A number of scholars have suggested that a new paradigm of work, often called high performance , is emerging that offers such workers more skilled jobs and higher wages. Using a unique national dataset, we find little evidence that practices associated with high-performance work systems are associated with higher wages.     

Affirmative Action and the Occupational Advancement of Minorities and Women During 1973–2003

The share of minorities and women comprising high‐paying skilled occupations such as management, professional, and technical occupations has been increasing since the 1960s, while the proportion of white men in such occupations has been declining. What has been the contribution of affirmative action to the occupational advancement of minorities and women from low‐wage unskilled occupations into high‐wage skilled ones in U.S. firms? I examine this by comparing the occupational position of minorities and women at firms holding federal contracts, and thereby mandated to implement affirmative action, and noncontracting firms, over the course of 31 years during 1973–2003. I use a new longitudinal dataset of over 100,000 large private‐sector firms across all industries and regions uniquely suited for the exploration of this question obtained from the U.S. Equal Employment Opportunity Commission. My key findings show that the share of minorities and women in high‐paying skilled occupations grew more at federal contractors subject to affirmative action obligation than at noncontracting firms during the three decades under study, but these advances took place primarily during the pre‐ and early Reagan years and during the decade following the Glass Ceiling Act of 1991.     

Incentive Compensation and the Likelihood of Termination: Theory and Evidence from Real Estate Organizations

We analyze two managerial compensation incentive devices: the threat of termination and pay for performance. We first develop a simple model predicting that these devices are substitutes: when termination incentives are low, optimal contracts provide stronger pay‐for‐performance incentives. We then use data from real estate organizations to provide two independent tests of the model’s central prediction. First, we use the fact that chief executive officers of Real Estate Investment Trusts (REITs) and general partners of Real Estate Limited Partnerships (RELPs) perform similar tasks, yet organizational features of RELPs ensure that the latter are much harder to terminate. Consistent with the model, we find that pay‐for‐performance sensitivity is much higher for general partners of RELPs, where the termination threat is less credible. Second, we use a recent cross‐section of REITs to show that in property types where it is expected to be more costly to replace managers, those managers have stronger pay‐for‐performance incentives.     

Management,Organizational Justice and Emotional Exhaustion among Chinese Migrant Workers: Evidence from two Manufacturing Firms

This article explores how Human Resource (HR) policies and practices influence employee perceptions of organizational justice, which in turn impacts employee emotions and feelings of emotional exhaustion. Using structural equation modelling and based on employee survey data drawn from two manufacturing organizations, we find that a strong HR system — perceived by workers as distinctive, attractive and consistently implemented — fosters perceptions of distributive, procedural and interactive justice. However, only distributive injustice leads to negative emotions and emotional exhaustion. This is explained by reference to the cultural and institutional context (China), status (migrant) and type of workers (semi‐skilled, manual) included in the study. We discuss the theoretical and practical implications that arise from these findings.
