Abstract

"We use a microeconomic approach to analyze the effects of minimum wages. Agents are allowed to have different productivities at different principals as well as different costs of working. We obtain several new and interesting effects. Minimum wages could influence the generated surplus when leaving employment unaffected, and destroy jobs that generate relatively high levels of surplus when affecting employment. Furthermore, minimum wages could harm agents even if these stay employed, while principals could benefit from them. We provide a complete characterization of the effects and show that these hold independently of the specific bargaining procedure and information structure." (Author's abstract, IAB-Doku) ((en))

Abstract

"We present the first causal analysis of a seven-year run-up of minimum wages to $15. Using a novel stacked county-level synthetic control estimator and data on fast-food restaurants, we find substantial pay growth and no disemployment. Our results hold among lower-wage counties and counties without local minimum wages. Minimum wage increases reduce Separation rates and raise wages faster than prices at McDonald’s stores; both findings imply a monopsonistic labor market with declining rents. In the tight post-pandemic labor market, when laborsupply becomes more elastic, we find positive employment effects. These become larger and statistically significant after addressing pandemic-response confounds." (Author's abstract, IAB-Doku) ((en))

Abstract

"This paper develops a spatial general equilibrium job search model to study the effects of local and universal minimum wage policies on employment, wages, job postings, vacancies, migration, and welfare. Workers search for jobs locally and in neighboring areas, deciding whether to migrate or commute after receiving remote offers. The model, estimated using ACS and QWI data, reliably forecasts commuting responses to city minimum wage hikes. Simulations show that low-skill (noncollege) workers benefit from local wage increases up to $12.50. The greatest per capita welfare gain for all workers is achieved by a $15.25 universal minimum wage." (Author's abstract, IAB-Doku) ((en))

Abstract

"Purpose: This paper investigates the impact of quasi-exogenous and substantial increases in the minimum wage on child labor outcomes in Türkiye. The study aims to provide empirical evidence on how minimum wage policies affect child labor outcomes in a developing country context, with a focus on gender and age differences. It seeks to understand whether minimum wage increases lead to a reduction in child labor and whether the impact is different for various demographic groups. Design/methodology/Approach: The research employs a difference-in-differences methodology using data from the 2012 and 2019 Child Labor Force Survey in Türkiye. The treatment group consists of children from households with minimum wage earners, while the control group comprises children from other households. Various labor market outcomes are analyzed, and robustness checks are performed. Findings: Our findings indicate that while the overall effect of minimum wage increases on child labor is statistically insignificant, there are notable heterogeneous impacts across different demographic groups and employment sectors. Specifically, we observe a significant reduction in the employment probability of girls under the age of 15 and unpaid family workers. Additionally, the likelihood of younger children being wage earners decreases, and the minimum wage increase reduces employment in the agriculture and services sectors for certain subgroups. The impact is also more limited for children in single-adult-worker households. Social implications: These results underscore the varying effects of minimum wage policies on child labor and highlight the importance of considering demographic and sectoral differences in policy formulation. Policymakers should complement such policies with income-generating programs and targeted education initiatives to address child labor issues more comprehensively and sustainably. Originality/value: This study fills a critical gap in the limited international literature on the causal effects of minimum wage policies on child labor incidence. One notable exception, Menon and van der Meulen Rodgers (2018) have explored the impact of minimum wage on child labor in India using regional variation, our study uniquely analyzes the effects at the household level in Türkiye. This approach provides valuable insights into how minimum wage changes affect child labor outcomes in a developing economy context with a high prevalence of minimum wage earners. It also contributes to the broader economic understanding of child labor and household income dynamics." (Autorenreferat, IAB-Doku, © Emerald Group)

Abstract

"Minimum wages generate an asymmetric pass-through of firm shocks across workers. We establish this result leveraging employer-employee data on Italian metalmanufacturing firms, which face different wage floors that vary within occupations. In response to negative firm productivity shocks, workers close to the wage floors experience higher job separations but no wage loss. However, the wage of high-paid workers decreases, and more so in firms with higher incidence of minimum wages. A neoclassical model with complementarities across workers with different skills rationalizes these findings. Our results uncover a novel channel that tilts the welfare gains of minimum wages toward low-paid workers." (Author's abstract, IAB-Doku) ((en))

Abstract

"This study examines the influences of minimum wage on self-employment exits, using recent changes in the minimum wage level in South Korea. Using the cross-industry variation on the impact of the minimum wage—the proportion of workers whose wages are below the minimum wage in the upcoming year—combined with individual longitudinal data, I estimate the model of self-employment exits. Overall, the estimates show that the minimum wage hike has no significant impact on self-employed workers. However, it increases the likelihood of the business closing for the self-employed who hire employees. The results imply that a ten percent increase in the minimum wage raises the exit probability by 2.6 percentage points, which is 30.9 % of the average exit rate for those with employees. Moreover, the exits are significantly associated with the transition to non-employment." (Author's abstract, IAB-Doku, © 2024 Elsevier) ((en))

Abstract

"We investigate the impact of the minimum wage on individuals’ post-secondary schooling decisions. Using Canadian longitudinal data, we explore 136 minimum wage amendments and find three novel results. First, the minimum wage affects both thequantity and type of human capital acquired by students. A 10% increase in the minimum wage increases community-college enrollment by 6.2% but reduces University enrollment by 6.5%. Second, high minimum wages widen the university participation gap between individuals with different levels of parental education. Finally, Minimum wage hikes encourage workers who recently separated from their job to return to post-secondary education as mature students" (Author's abstract, IAB-Doku) ((en))

Abstract

"This paper examines the impact of unions on unemployment and wages in a dynamic equilibrium search model. We model a union as imposing a minimum wage and rationing jobs to ensure that the union's most senior members are employed. This generates rest unemployment, where following a downturn in their labor market, unionized workers are willing to wait for jobs to reappear rather than search for a new labor market. We characterize the hazard rate of exiting unemployment, and show that it is low at long durations whenever the union-imposed minimum wage is high; we establish that a high union-imposed minimum wage generates a compressed wage distribution and a high turnover rate of jobs —properties consistent with the data. Finally, we show that seniority rules lead to lower unemployment levels, relative to an alternative rule allocating jobs to workers randomly." (Author's abstract, IAB-Doku, © 2024 Elsevier) ((en))

Abstract

"This paper studies how minimum wages affect the wage distribution if firms face financial constraints. Using German employer-employee data and firm balance sheets, we document that the within-firm wage dispersion decreases more with higher minimum wages when firms are financially constrained. We introduce financial frictions into a search and matching labor market model with stochastic job matching, imperfect information, and endogenous effort. In line with the empirical literature, the model predicts that a higher minimum wage reduces hirings and separations. Firms become more selective such that their employment and wage dispersion fall. If effort increases strongly, firms may increase employment at the expense of higher wage dispersion. Financially constrained firms are more selective and reward effort less. As a result, within-firm wage dispersion and employment in these firms fall more with the minimum wage." (Author's abstract, IAB-Doku, © 2024 Elsevier) ((en))

Abstract

"Spain increased its minimum wage (MW) by 22% in 2019. Given the intense debate in the economic literature on the impact of MW increases on the labour market, we conduct an impact assessment of this policy. The synthetic control method will be used to replicate the Spanish labour market by means of a pool of European countries that, in the absence of other reliable measures, simulates the evolution of Spanish employment. This will allow us to identify the causal effect from the increase in the MW. After applying the technique, the increase in the MW is found to have no effect on employment. The results have been subjected to robustness tests such as leave one out or segmentation by gender or age." (Author's abstract, IAB-Doku) ((en))

Abstract

"Minimum wages protect workers from unjustified low wages and ensure a level playing field for companies. All EU Member States and Norway have minimum wages in place, albeit in different forms. Among the 27 Member States, 22 have a national minimum wage, with one (or sometimes more than one) rate setting a basic wage floor. In addition, collective agreements are used to further regulate pay and usually set rates above the national minimum wage. In the remaining five Member States and Norway, minimum wages are set in sectorlevel collective agreements, which includes a high coverage of workers in these countries. The 2024 version of this annual review provides an update on minimum wage developments, details how the rates were set and which criteria were used in their adjustment, and maps the influence of EU-level policy on minimum wage setting."

Abstract

"This paper shows that more highly concentrated labor markets experience more positive employment effects of the minimum wage. In the most concentrated labor markets, employment rises following a minimum wage increase. The paper establishes its main findings by studying the effects of local minimum wage increases on a key low-wage retail sector, and using data on labor market concentration that covers the entirety of the U.S. with fine spatial variation at the occupation level. The results carry over to the fast-food sector and the entire low-wage labor market and are robust to using proxies of labour market concentration available for a broader range of industries, such as the number of establishments and population density. A model of oligopsonistic competition can explain these effects: there is more room to increase wages in high-concentration areas where wages tend to be further below marginal productivity. These findings provide evidence supporting monopsonistic wage setting as an explanation for the near-zero minimum wage employment effect documented in prior work."

Abstract

"The authors estimate the effects of an increase in the youth minimum wage in the Netherlands on low-paid workers’ employment and earnings, using a difference-in-differences approach with detailed administrative data. Findings show that the increase does not have a negative effect on the number of jobs or hours worked, hence raising overall earnings for affected workers. Further, the minimum wage increase has substantial spillover effects, accounting for close to 70% of the average wage increase experienced by workers. While employment grows in fixed-term and temporary help agency contracts, the authors do not find evidence of declines in employment in other types of work arrangements, nor of labor-labor substitution. Labor market outcomes evolve most favorably for full-time incumbent workers who are not enrolled in education and are thus less likely to be transient occupants of minimum wage jobs."

Abstract

"We evaluate the distributional effects of a minimum wage introduction based on a data set with a moderate sample size but a large number of potential covariates. Therefore, the selection of relevant control variables at each distributional threshold is crucial to test hypotheses about the impact of the treatment. To this end, we use the post-double selection logistic distribution regression approach proposed by Belloni et al. (2018a), which allows for uniformly valid inference about the target coefficients of our low-dimensional treatment variables across the entire outcome distribution. Our empirical results show that the minimum wage crowded out hourly wages below the minimum threshold, benefitted monthly wages in the lower middle but not the lowest part of the distribution, and did not significantly affect the distribution of hours worked."

Abstract

"We structurally estimate an equilibrium search model using German administrative data and use the model for counterfactual analyses of a uniform minimum wage. The model with worker and firm heterogeneity does not restrict the sign of employment effects a priori; it allows for different job offer arrival rates for the employed and the unemployed and lets firms optimally choose their recruiting intensity. We find that unemployment is a non-monotonic function of the minimum wage level. Effects differ strongly by labor market segment defined by region, skill, and permanent worker ability."

Abstract

"We present the first empirical evidence on the 22 percent increase in the German minimum wage, implemented in 2022, raising it from Euro 9.82 to 10.45 in July and to Euro 12 in October. Leveraging the German Earnings Survey, a large and novel data source comprising around 8 million employee-level observations reported by employers each month, we apply a difference-in-difference-in-differences approach to analyze the policy's impact on hourly wages, monthly earnings, employment, and working hours. Our findings reveal significant positive effects on wages, affirming the policy's intended benefits for low-wage workers. Interestingly, we identify a negative effect on working hours, mainly driven by minijobbers. The hours effect results in an implied labor demand elasticity in terms of the employment volume of -0.17 which only partially offsets the monthly wage gains. We neither observe a negative effect on the individual's employment retention nor the regional employment levels." (Author's abstract, IAB-Doku) ((en))

Abstract

"In 2015, Germany introduced a national minimum wage. While the literature agrees on at most limited negative effects on the overall employment level, we go into detail and analyze the impact on the working hours dimension and on the subset of minijobs. Using data from the German Structure of Earnings Survey in 2010, 2014, and 2018, we find empirical evidence that the minimum wage significantly reduces inequality in hourly and monthly wages. While various theoretical mechanisms suggest a reduction in working hours, these remain unchanged on average. However, minijobbers experience a notable reduction in working hours which can be linked to the specific institutional framework. Regarding employment, the results show no effects for regular jobs, but there is a noteworthy decline in minijobs, driven by transitions to regular employment and non-employment. The transitions in non-employment imply a wage elasticity of employment of $-0.1$ for minijobs. Our findings highlight that the institutional setting leads to heterogeneous effects of the minimum wage." (Author's abstract, IAB-Doku) ((en))

Abstract

"Using data from the 2011–2019 China Household Finance Survey (CHFS), this paper examines the effect of minimum wage increases on the gender wage gap. The results show that minimum wage increases can significantly reduce the gender wage gap. We further examine the impact of minimum wages on the gender wage gap across the wage distribution and find that minimum wages are conducive to narrowing the gender wage gap at the bottom and middle parts of the wage distribution, but not conducive to reducing the gender wage gap at the upper part of the wage distribution. We also identity heterogeneous effects of minimum wages on the gender wage gap across age, education level, hukou, and work unit. Finally, we find that minimum wages have a negative effect on low-wage workers’ employment. Therefore, governments need to weigh their role in reducing the gender wage gap against the potential negative employment effects when adjusting the minimum wage standard."
