The Value of Early-Career Skills
Christina Langer, Simon Wiederhold
CESifo Working Paper,
No. 10288,
2023
Abstract
We develop novel measures of early-career skills that are more detailed, comprehensive, and labor-market-relevant than existing skill proxies. We exploit that skill requirements of apprenticeships in Germany are codified in state-approved, nationally standardized apprenticeship plans. These plans provide more than 13,000 different skills and the exact duration of learning each skill. Following workers over their careers in administrative data, we find that cognitive, social, and digital skills acquired during apprenticeship are highly – yet differently – rewarded. We also document rising returns to digital and social skills since the 1990s, with a more moderate increase in returns to cognitive skills.

Joint Economic Forecast 2/2022: Energy crisis: inflation, recession, welfare loss
The crisis on the gas markets is having a severe impact on the German economy. Soaring gas prices are drastically increasing energy costs, leading to a massive reduction of the purchasing power. Despite a decline in the second half of the year, gross domestic product is expected to expand by 1.4% this year. For the coming year, the institutes expect a contraction by 0.4%, followed by an increase of 1.9% in 2024.

Immigration and Entrepreneurship in the United States
Pierre Azoulay, Benjamin Jones, J. Daniel Kim, Javier Miranda
American Economic Review: Insights,
No. 1,
2022
Abstract
Immigration can expand labor supply and create greater competition for native-born workers. But immigrants may also start new firms, expanding labor demand. This paper uses U.S. administrative data and other data resources to study the role of immigrants in entrepreneurship. We ask how often immigrants start companies, how many jobs these firms create, and how these firms compare with those founded by U.S.-born individuals. A simple model provides a measurement framework for addressing the dual roles of immigrants as founders and workers. The findings suggest that immigrants act more as "job creators" than "job takers" and that non-U.S. born founders play outsized roles in U.S. high-growth entrepreneurship

Hysteresis from Employer Subsidies
Emmanuel Saez, Benjamin Schoefer, David Seim
Journal of Public Economics,
August
2021
Abstract
This paper uses administrative data to analyze a large and 8-year long employer payroll tax rate cut in Sweden for young workers aged 26 or less. We replicate previous results documenting that during the earlier years of the reform, it raised youth employment among the treated workers, driven by labor demand (as workers’ take-home wages did not respond). First, drawing on additional years of data, this paper then documents that the longer-run effects during the reform are twice as large as the medium-run effects. Second, we document novel labor-demand-driven “hysteresis” from this policy – i.e. persistent employment effects even after the subsidy no longer applies – along two dimensions. Over the lifecycle, employment effects persist even after workers age out of eligibility. Three years after the repeal, employment remains elevated at the maximal reform level in the formerly subsidized ages. These hysteresis effects more than double the direct employment effects of the reform. Discrimination against young workers in job posting fell during the reform and does not bounce back after repeal, potentially explaining our results.

Fehlende Fachkräfte in Deutschland – Unterschiede in den Betrieben und mögliche Erklärungsfaktoren: Ergebnisse aus dem IAB-Betriebspanel 2018

Abstract
In the years after the economic crisis, the economic situation of establishments in West and East Germany has improved steadily. At the same time, increased labor market dynamics and a positive trend in total employment can be observed. Also the demand for skilled employees reached a new high of 2.7 million in 2018. Only about 60 percent of the demand could be covered, which is also reflected in a further increase of the so-called non-occupancy quota. With regard to the distribution of this indicator for skilled labor shortages, we observe clear sector- and size-specific differences as well as regional heterogeneity. The quota is particularly high in the construction industry and in agriculture and forestry, with more than half the positions left vacant. A positive correlation between shortages of skilled labor and the use of temporary work, flexible working hours and investments in vocational training and further education is assessed in a multivariate analysis. The structure of formal occupational skill requirements did not change very much over recent years. However, a clear trend towards more flexible work organization can be observed. For example, about one quarter of the establishments offer teleworking. The share of part-time employment is also increasing nationwide, especially in sectors with a higher proportion of women, such as the service industries or the public sector. The share of marginal employment is particularly high in sectors that are characterized by cyclical and/or seasonal demand fluctuations or comparatively unspecific skill requirements – and above-average shortages of skilled labor. In 2018, the proportion of establishments authorized to provide in-house vocational training rose for the first time since 2010 – to 54 percent in Germany. In Eastern Germany, the share is significantly lower at 49 percent. The proportion of authorized establishments that actually train apprentices has been relatively stable at around 50 percent for several years. Both successfully occupied and vacant apprenticeships are distributed very heterogeneously across sectors. The recruitment rate of successful graduates is about three quarters. In establishments with skilled labor shortages, both the training rate and the graduate hiring rate are higher, suggesting that vocational training is already used here as an alternative strategy for recruiting skilled employees. The share of establishments supporting further education of their employees remains stable at about fifty percent for several years, and the proportion of employees participating in training is still about one third. A comparatively higher rate of further education among unskilled employees in establishments with skilled labor shortages indicates that internal resources are being increasingly used here to meet the demand for skilled employees.

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.
