Longitudinal Wealth Data and Multiple Imputation: An Evaluation Study

Statistical analysis in surveys is generally facing missing data. In longitudinal studies for some missing values there might be past or future data points available. The question arises how to successfully transform this advantage into improved imputation strategies. In a simulation study the authors compare six combinations of cross-sectional and longitudinal imputation strategies for German wealth ...

Real Estate Price Polarization Projected to Increase until 2030 in Germany

Demographic projections for Germany indicate a drop in the population of many regions by 2030. This is likely to have an impact on the real estate market. Our report presents the result of a model calculation of asking prices for residential real estate in Germany up to 2030 based on market data from empirica-systeme GmbH and a population projection from the Bertelsmann Foundation. Depending on the ...

Access to urban green space and environmental inequalities in Germany

Although sufficient and equitable access to urban green represents a key aspect for adequate living conditions and a healthy environment in urban areas, national studies investigating the provision of urban green on household and individual level are scarce. We present a study investigating access to urban green space and environmental inequalities in German major cities by merging geo-coded household ...

Accessibility of urban blue in German major cities

Action 5 of the EU 2020 Biodiversity Strategy explicitly mentions that EU member states, with assistance of the Commission, will map and assess the state of ecosystems and ecosystem services in their national territory by 2014. Water represents an important landscape element and contributes to human health and well-being in urban areas. However, in Germany – like in many other European countries – ...

Sample selection models for count data in R

We provide a detailed hands-on tutorial for the R package SemiParSampleSel (version 1.5). The package implements selection models for count responses fitted by penalized maximum likelihood estimation. The approach can deal with non-random sample selection, flexible covariate effects, heterogeneous selection mechanisms and varying distributional parameters. We provide an overview of the theoretical ...

Trade-Off Between Consumption Growth and Inequality: Theory and Evidence for Germany

This paper examines the structure and evolution of consumption inequality. Once heterogeneous agents relate their neighbors' consumption to their own, consumption volatility and inequality are affected. The model predicts a positive relationship between the group specific average consumption growth and within-group inequality, which is empirically confirmed using survey data from the German Socio-Economic ...

Consumption Growth and Inequality in a Heterogeneous Agent Model: Theory and Evidence from German Data

This paper studies the structure and dynamics of consumption and consumption growth inequality. The theoretical framework is a heterogeneous agent model with stochastic labor endowments, where the group mean consumption serves as consumption externality. The main finding is that households' preferences affect the within-group inequality through asset holding decisions: it decreases with groups' ...

Take Me “Home”: Determinants of Return Migration Among Germany’s Elderly Immigrants

This paper examines the determinants of return migration as foreign-born individuals approach old age in Germany. Return migration in later life engages a different set of conditions than return migration earlier on, including framing return as a possible retirement strategy. Using data from the German Socioeconomic Panel, results suggest that later-life emigrants are “negatively selected” on the basis ...

Getting Older, Getting Poorer? A Study of the Earnings, Pensions, Assets and Living Arrangements of Older People in Nine Countries

The impact of music on educational attainment

This paper analyzes the impact of music practice on educational outcomes. Estimates from multivariate regressions and individual fixed effects suggest that childhood musical activity—either playing an instrument or singing—relates positively to educational achievements in adolescence. The magnitude and significance of the estimated music coefficients for different music indicators is robust when increasing ...
