Centre-Based Care and Parenting Activities

We examine the relationship between parenting activities and centre-based care using time diary and survey data for mothers in Germany. While mothers using centre-based care spend significantly less time in the presence of their child, we find that differences in the time spent on specific activities such as reading, talking, and playing with the child are relatively small or zero. The pattern of results ...

Using machine learning to uncover the relation between age and life satisfaction

This study applies a machine learning (ML) approach to around 400,000 observations from the German Socio-Economic Panel to assess the relation between life satisfaction and age. We show that with our ML-based approach it is possible to isolate the effect of age on life satisfaction across the lifecycle without explicitly parameterizing the complex relationship between age and other covariates—this ...

Economic education at the expense of indoctrination? Evidence from Germany

We study the impact of a recent curriculum reform introducing mandatory economic education in higher-track secondary schools in Southwest Germany. The curriculum reform provides the opportunity to leverage the exogenous variation in exposure to economic education relative to the previous cohort not affected by the reform. One year after exposure to the mandate, we observe positive treatment effects ...

Datenanalyse: Wie Studenten über Einwanderung denken

Im Osten ist die Skepsis gegenüber Migranten auch unter Studenten größer als im Westen – aber Daten zeigen eine Annäherung. Ein Gastbeitrag.

Causality in the Link between Income and Satisfaction: IV Estimation with Internal Instruments

Usually, it is expected that income increases life satisfaction. In recent years tough, research emerged that shows how subjective well-being, including satisfaction, influences objective measures, as for example income. This would then require explicit identification strategies for estimating effects of income on life satisfaction. I address this issue using German SOEP data and Lewbel’s (2012) method, ...

Separating PIAAC competencies from general cognitive skills: A dimensionality and explanatory analysis

This study aims to investigate how test scores from PIAAC (Programme for the International Assessment of Adult Competencies) can be interpreted, by comparing the PIAAC competencies literacy and numeracy to reasoning and perceptual speed. Dimensionality analyses supported, that the PIAAC competencies can be separated into a common factor overlapping with reasoning and perceptual speed, and domain-specific ...

Loneliness During a Nationwide Lockdown and the Moderating Effect of Extroversion

Loneliness levels were assessed in a longitudinal, nationwide sample (N total = 6,010) collected over the course of the first 3 months of the COVID-19 pandemic in Germany. When in-person social contact restrictions were put in place, loneliness increased significantly compared to prepandemic levels but began to decrease again even before contact restrictions were eased. The loneliness costs were distributed ...

Pessimistische Eltern, pessimistische Kinder?: Die beruflichen Zukunftserwartungen Jugendlicher im sozioökonomischen Familienkontext

Socioeconomic Status and Inequalities in Children’s IQ and Economic Preferences

This paper explores inequalities in IQ and economic preferences between children from families of high and low socioeconomic status (SES). We document that children from high-SES families are more intelligent, patient, and altruistic as well as less risk seeking. To understand the underlying mechanisms, we propose a framework of how SES, parental investments, as well as maternal IQ and preferences ...

Limited Self-knowledge and Survey Response Behavior

We study response behavior in surveys and show how the explanatory power of self-reports can be improved. First, we develop a choice model of survey response behavior under the assumption that the respondent has imperfect self-knowledge about her individual characteristics. In panel data, the model predicts that the variance in responses for different characteristics increases in self-knowledge and ...
