Veranstaltungsreihe: IAB-Colloquium (en)

The discussion series “Labour Market and Occupational Research (IAB-Colloquium zur Arbeitsmarkt- und Berufsforschung)” is a forum where primarily external researchers present the results of their work and discuss these with experts from IAB. Practitioners from the political, administrative and business fields are naturally also welcome.

Social disparities in track choices are a well-known mechanism for the intergenerational reproduction of inequality. School guidance may help reducing such disparities by narrowing information gaps and by reducing the family influence on students’ decision making. We investigate the potential equalizing role of guidance programs by analysing an intervention carried out in Italy, where students are tracked at age 14 and teacher recommendations are non-binding. The intervention took place in 2018 in the city of Turin and involved 40% of all eighth-grade students, shortly before their transition from comprehensive to tracked education. The students attended four two-hour sessions designed to provide them with information about the educational system and related job market opportunities, and to raise their awareness of their aptitudes and inclinations. We expected the programme to be of particular benefit to low socio-economic status (SES) and migrant students and thus to reduce social gaps in track choices. We adopted a mixed-method research design: with quantitative analyses based on a combination of propensity-score-matching and differences-in-differences techniques, we compared the outcomes of comparable students from the 2017 and 2018 cohorts who were or were not exposed to the intervention in order to assess its impact on inequality; additionally, we use qualitative non-participatory observation to unveil the actual content and implementation of the program and the behaviour of the key actors. We find that while the program contributed to reducing indecision, probably by compelling students to reflect more carefully about their decisions during this crucial transition, it did not have any major effect on social inequalities. Results from the qualitative analysis help us shed light on the mechanisms at play behind this lack of effect. In particular, the heavy emphasis placed on current achievement records, dropout risks, and (short-term) labour-market outcomes may counteract the equalizing potential of the program by pushing low-SES and migrant students towards vocational tracks.

We analyze the effects of large-scale local public infrastructure investments on economic development, exploiting the infrastructure shock following when Brazil was awarded the 2014 FIFA World Cup. We place particular emphasis on effect heterogeneity with respect to the type, location, temporal evolution, and costs and benefits of the investments. Using novel data on monthly night light luminosity at the municipal district level as a proxy for economic activity, we apply Difference-in-Differences and event studies for estimation. Overall, we find strongly positive impacts both in the short and longer run. However, a closer examination reveals that effects are larger and longer-lasting for transport infrastructure as opposed to sports infrastructure, and they are more pronounced in smaller areas. Importantly, we quantify significant negative spatial spillovers. Factoring them in, we still find positive net benefits of transport infrastructure investments two years after the tournament.

While many countries are discussing substantial increases in the minimum wage, policy makers lack a comprehensive analysis of the macroeconomic and distributional consequences of raising the minimum wage. This paper investigates how employment, output and worker welfare respond to increases in the minimum wage beyond observable levels -- both in the short- and long run. To that end, I incorporate endogenous job search effort, differences in employment levels, and a progressive tax-transfer system into a search-matching model with worker and firm heterogeneity. I estimate my model using German administrative and survey data. The model replicates the muted employment response, as well as the reallocation effects in terms of productivity and employment levels documented by reduced form research on the German introduction of a federal minimum wage in 2015.  Simulating the model, I find that long-run employment increases slightly until the minimum wage is equal to 60% of the full-time median wage (Kaitz index) as higher search effort offsets lower vacancy posting. In addition, raising the minimum wage reallocates workers towards full-time jobs and high-productivity firms. Total hours worked and output peak at Kaitz indices of 73% and 79%. However, policy makers face an important inter-temporal trade-off as large minimum wage hikes lead to substantial job destruction, unemployment and recessions in the short-run. Finally, I show that raising the minimum wage largely benefits men. For women, who often rely on low-hours jobs, the disutility from working longer hours outweighs the utility of higher incomes.

The presentation offers an overview about the new data service of the Research Data Centre of the Federal Office for Migration and Refugees (BAMF-FDZ). The BAMF-FDZ gives access to register and survey data for migration and integration research. The presentation will introduce the available and future data sets and discuss advantages and limitations. In addition, the application procedure is also explained.

Civil society has played an important role in meeting the challenges of refugee migration in recent years. This policy report studies the importance of civic engagement for the integration of refugees by employing several waves of the IAB-BAMF-SOEP survey data. Using the density of newly established associations at the county level as a measure of civic engagement of a region, we exploit regional differences in civic engagement in order to estimate its association with individual integration outcomes of refugees. We find that in regions with particularly high levels of civic engagement, refugees have significantly more frequent contact to Germans, higher life satisfaction and better German language skills. This correlation is robust to controlling for the local population structure, economic strength and labor market situation. In terms of language acquisition, women and refugees with a low level of education benefit the most from high civic engagement. Moreover, refugees with university degrees find significantly better-paying jobs in areas with higher civic engagement. However, no direct correlation could be established between civic engagement and the likelihood that refugees are active in the labor market. Nonetheless, the results suggest that support from civil society translates into improved access to government benefits. Our findings stress that local civic engagement is an important complement to public assistance services and policy makers should give a high priority to team up with civil society to improve refugees' integration outcomes.

Natural disasters are growing in frequency globally. Understanding how vulnerable populations respond to these disasters is essential for an effective policy response. This paper explores the short- and long-run consequences of the 1906 San Francisco Fire, one of the largest urban fires in American history. Using linked Census records, I follow residents of San Francisco and their children from 1900 to 1940. Historical records suggest that exogenous factors such as wind and the availability of water determined where the fire stopped. I implement a spatial regression discontinuity design across the boundary of the razed area to identify the effect of the fire on those who lost their home to it. I find that in the short run, the fire displaced affected residents, forced them into lower-paying occupations and out of entrepreneurship. Experiencing the disaster disrupted children’s school attendance and led to an average loss of six months of education. While most effects attenuated over time, the negative effect on business ownership persists even in 1940, 34 years after the fire. Therefore, my findings reject the hope for a “reversal of fortune” for the victims, in contrast to what is found for more recent natural disasters such as hurricane Katrina.

This paper presents estimates of the causal effect of the default marital property regime on female labour supply, fertility, marriage, and marital dissolution rates utilising the regional variation in the default marital property system in Spain and the 2005 divorce reform. Property rights theory predicts that under contractual incompleteness ownership of physical assets affects investments, and that joint ownership provides the strongest incentives to make relationship-specific investments, while non-integration encourages non-specific investments. My findings are consistent with these predictions: separation of property promotes higher female labour supply, having no more than two children, and a lower marriage rate than community property. The divorce rate remains largely unaffected by the property regime type.

This paper examines how and why returning to education to attain a high school diploma combats earnings penalties due to negative employment shocks. High school dropout continues to be a problem, particularly as employment is increasingly skilled over time. Following a policy expanding a Norwegian vocational certification scheme, displaced workers certify their skills at significantly higher rates relative to those displaced pre-expansion. Increases in certification post-expansion significantly reduce income losses after job loss. Certifying skills fosters recovery among early career displaced workers through the retention of relevant industry-specific human capital, which increases job stability over 20 years later.

We study the long-run effects of soft commitments and reminders on academic performance. In a randomized field experiment, our first treatment consisted of sending students in a 7-semester bachelor's degree program reminders about the recommended study structure each semester. The second treatment group received the same reminders but in the first semester were on top offered the opportunity to commit to the recommended study structure with a non-binding agreement. After 5 years, we find that the reminders did not generate any effects on academic performance. The soft commitment device treatment on the other hand is highly effective: after 5 years, students in the commitment treatment are 14 percentage points more likely to have graduated, 9 percentage points less likely to have dropped out, and their time to graduation is 0.35 semesters shorter than that of the controls – while maintaining the same GPA as the controls.

People who say that they are better off socioeconomically are healthier than those who say that they are worse off, even when only comparing people whose objective socioeconomic status is the same. This association between perceived socioeconomic status and health has intrigued social scientists for various reasons. Some suggest that the finding shows that it is feelings of inferiority by which social conditions "come under the skin." Others suggest that it shows how our objective measures of  socioeconomic status fail to capture stratification in contemporary societies. In our study, we take a step back to re-examine the perceived socioeconomic status-health association in the English Longitudinal Study of Aging (ELSA). Using hybrid, within-between panel regression models and allostatic load as biomarker health outcome, we show that perceived socioeconomic status is only associated with health in comparisons across individuals, in within-specifications where participants serve as their own controls, no association can be found. In a further step, we show how the between-participant association is driven by personality traits and childhood experiences. We discuss the implications of our findings.
