We show that in school systems with grade retention or redshirting birth cohort size is negatively related to the grade-level share of students who are too old for their grade. This compositional effect gives rise to an upward bias in estimates of class size effects based on commonly used research designs exploiting within-school variation in birth cohort size. Using data for all primary schools in ...

Understanding widowhood duration is essential for individuals and effective widow support policies, yet widowhood duration remains an understudied topic. In this article, we provide a quantitative estimation of the impact of three primary determinants of expected widowhood duration at age 60 in a unified framework: (1) the degree of overlap between male and female mortality distributions, (2) the spousal ...

We examine the association between cohabitation and women’s and men’s wealth, closely considering the distinct regulatory and normative contexts in France and Eastern and Western Germany. Using longitudinal data from the German Socio- Economic Panel Study (2002–2017) and the French wealth survey Histoire de Vie et Patrimoine (2014/15-2020/21), we apply fixed-effects regression models to examine potential ...

Nitrate pollution from agricultural production is a major threat to water resources worldwide. This study quantifies the consequences of groundwater nitrate pollution for the drinking water supply sector by estimating the effect of groundwater nitrate pollution on the costs of water utilities. In doing so, we contribute to the estimation of the external costs of agricultural nonpoint pollution associated ...

This study investigated how changing the mode of incentive administration between two panel waves, spaced six months apart, affected longitudinal survey response. A split-ballot incentive experiment was used to compare shifting from an unconditional pre-paid incentive mode in the first wave to a conditional post-paid mode in the second wave, versus consistently using a conditional post-paid mode across ...

Individuals vary considerably in how much they earn during their lifetimes. This study examines the role of the tax‐and‐transfer system in mitigating such inequalities, which could otherwise lead to disparities in living standards. Utilizing a life‐cycle model, we determine that the tax‐and‐transfer system offsets 45% of lifetime earnings inequality attributed to differences in productive abilities ...

Who makes it to the top? We use the leading socio-economic survey in Germany, supplemented by extensive data on the rich, to answer this question. We identify the key predictors for belonging to the top 1 percent of income, wealth, and both distributions jointly. Although we consider many, only a few traits matter: Entrepreneurship and self-employment in conjunction with a sizable inheritance of company ...

We analyse variation in firm performance as a function of the international diversification of ICT imports by firms. Drawing on administrative data from 2010 and 2014 on nearly 4000 German manufacturing firms, we find that firms with ICT sourcing that is diversified across multiple countries perform better than similar, less-diversified firms. This finding holds true for two performance metrics (value ...

In this article, we introduce the command beyondpareto, which estimates the extreme-value index for distributions that are Pareto-like, that is, whose upper tails are regularly varying and eventually become Pareto. The estimation is based on rank-size regressions, and the threshold value for the upper-order statistics included in the final regression is determined optimally by minimizing the asymptotic ...

Existing research has demonstrated that wealthier individuals differ in family formation. Potential explanations draw on wealth’s use and symbolic value as well as the relative economic bar of family formation. This study examines the relationship between wealth and three family formation events in Germany: first cohabitation, marriage, and birth. Data from the German Socio-Economic Panel Study (2002–2017) ...
