The Contribution of Employer Changes to Aggregate Wage Mobility

Abstract
Wage mobility reduces the persistence of wage inequality. We develop a framework to quantify the contribution of employer-to-employer movers to aggregate wage mobility. Using three decades of German social security data, we find that inequality increased while aggregate wage mobility decreased. Employer-to-employer movers exhibit higher wage mobility, mainly due to changes in employer wage premia at job change. The massive structural changes following German unification temporarily led to a high number of movers, which in turn boosted aggregate wage mobility. Wage mobility is much lower at the bottom of the wage distribution, and the decline in aggregate wage mobility since the 1980s is concentrated there. The overall decline can be mostly attributed to a reduction in wage mobility per mover, which is due to a compositional shift toward lower-wage movers.

Can Mentoring Alleviate Family Disadvantage in Adolescence? A Field Experiment to Improve Labor-Market Prospects

Journal of Political Economy,
No. 3,
2024
Abstract
We study a mentoring program that aims to improve the labor-market prospects of school-attending adolescents from disadvantaged families by offering them a university-student mentor. Our RCT investigates program effectiveness on three outcome dimensions that are highly predictive of later labor-market success: math grades, patience/social skills, and labor-market orientation. For low-SES adolescents, the mentoring increases a combined index of the outcomes by over half a standard deviation after one year, with significant increases in each dimension. Part of the treatment effect is mediated by establishing mentors as attachment figures who provide guidance for the future. Effects on grades and labor-market orientation, but not on patience/social skills, persist three years after program start. By that time, the mentoring also improves early realizations of school-to-work transitions for low-SES adolescents. The mentoring is not effective for higher-SES adolescents. The results show that substituting lacking family support by other adults can help disadvantaged children at adolescent age.

Mentoring Helps Highly Disadvantaged Adolescents

IEB Report "Education Policy: Quality and Equality of Opportunity",
2023
Abstract
In this report, we discuss the results of our randomized controlled trial (RCT) of a nationwide mentoring program designed to improve the labor-market prospects of disadvantaged adolescents in Germany (Resnjanskij et al., 2023). The study is motivated by the high persistence of inequality across generations present even in countries with comprehensive social welfare systems (Alvaredo et al., 2018). In particular, the school-to-work transition is a decisive moment that determines the differences in later labor-market outcomes of young adolescents.

The Intergenerational Transmission of Cognitive Skills

Abstract
Parents influence their children in many ways, but which family features actually cause the strong intergenerational linkages that we observe? This column presents the first causal evidence on cognitive skill transmission in the family. Using Dutch survey and registry data, the authors show that parents’ maths and language skills strongly affect the same skills in their children, and that skills within dynasties are not just genetically determined but are significantly affected by educational experiences. This highlights the importance of good educational environments in alleviating persistent inequalities.

O Brother, Where Start Thou? Sibling Spillovers on College and Major Choice in Four Countries

Abstract
Family and social networks are widely believed to influence important life decisions, but causal identification of those effects is notoriously challenging. Using data from Chile, Croatia, Sweden, and the United States, we study within-family spillovers in college and major choice across a variety of national contexts. Exploiting college-specific admissions thresholds that directly affect older but not younger siblings’ college options, we show that in all four countries a meaningful portion of younger siblings follow their older sibling to the same college or college-major combination. Older siblings are followed regardless of whether their target and counterfactual options have large, small, or even negative differences in quality. Spillover effects disappear, however, if the older sibling drops out of college, suggesting that older siblings’ college experiences matter. That siblings influence important human capital investment decisions across such varied contexts suggests that our findings are not an artifact of particular institutional detail but a more generalizable description of human behavior. Causal links between the postsecondary paths of close peers may partly explain persistent college enrollment inequalities between social groups, and this suggests that interventions to improve college access may have multiplier effects.

HIP, RIP, and the Robustness of Empirical Earnings Processes
Florian Hoffmann
Quantitative Economics,
No. 3,
2019
Abstract
The dispersion of individual returns to experience, often referred to as heterogeneity of income profiles (HIP), is a key parameter in empirical human capital models, in studies of life‐cycle income inequality, and in heterogeneous agent models of life‐cycle labor market dynamics. It is commonly estimated from age variation in the covariance structure of earnings. In this study, I show that this approach is invalid and tends to deliver estimates of HIP that are biased upward. The reason is that any age variation in covariance structures can be rationalized by age‐dependent heteroscedasticity in the distribution of earnings shocks. Once one models such age effects flexibly the remaining identifying variation for HIP is the shape of the tails of lag profiles. Credible estimation of HIP thus imposes strong demands on the data since one requires many earnings observations per individual and a low rate of sample attrition. To investigate empirically whether the bias in estimates of HIP from omitting age effects is quantitatively important, I thus rely on administrative data from Germany on quarterly earnings that follow workers from labor market entry until 27 years into their career. To strengthen external validity, I focus my analysis on an education group that displays a covariance structure with qualitatively similar properties like its North American counterpart. I find that a HIP model with age effects in transitory, persistent and permanent shocks fits the covariance structure almost perfectly and delivers small and insignificant estimates for the HIP component. In sharp contrast, once I estimate a standard HIP model without age‐effects the estimated slope heterogeneity increases by a factor of thirteen and becomes highly significant, with a dramatic deterioration of model fit. I reach the same conclusions from estimating the two models on a different covariance structure and from conducting a Monte Carlo analysis, suggesting that my quantitative results are not an artifact of one particular sample.

Gunnar Myrdal an the Persistence of Germany’s Regional Inequality
John B. Hall, Udo Ludwig
Journal of Economic Issues,
2009
Abstract
Der Beitrag lotet die Bedeutung des von G. Myrdal entwickelten „Konzepts der zirkulären und kumulativen Verursachung“ für die Erklärung von Konvergenz und Divergenz im wirtschaftlichen Angleichungsprozess zwischen Ost- und Westdeutschland aus. Das Konzept wird dem auf R. Barro und X. Sala-i-Martin zurückgehenden „ehernen Gesetz der Konvergenz“ gegenübergestellt. Die Autoren kommen zu dem Schluss, dass mit dem von Myrdal unterschiedenen Konter- und Ausbreitungseffekten in der wirtschaftlichen Entwicklung ein leistungsfähigerer Ansatz vorliegt, Ungleichheiten zwischen Ost und West zu verstehen.
