The Dog that Didn't Bark: What Item Nonresponse Shows about Cognitive and Non-Cognitive Ability

What survey respondents choose not to answer (item nonresponse) provides a useful task based measure of cognitive ability (e.g., IQ) and non-cognitive ability (e.g., Conscientiousness). Using the German Socio-Economic Panel (SOEP) and the National Longitudinal Survey of Youth 1997 (NLSY97), we find consistent correlation between item nonresponse and traditional measures of IQ and Conscientiousness. ...

The Effect of Rapid Structural Change on Workers

This paper deals with the question how workers’ labour market and non-monetary outcomes are impacted by a negative sector-specific labour demand shock. This issue is analysed in a setting of rapid structural change that happened in Eastern Germany after the fall of the Berlin Wall in 1989. The sector-specific labour demand shock can be assumed to be exogenous to other worker characteristics as it was ...

Perceived pollution and selective out-migration: revisiting the role of income for environmental inequality

The disproportionate exposure of minorities and socio-economically disadvantaged households to environmental pollution is often explained by selective migration or sorting mechanisms. Yet, previous empirical results remain inconclusive. Here, we offer an explanation for the mixed findings by focusing on the selective out-migration stage triggered by environmental pollution. We argue that many income-independent ...

Optimal minimum wages

We develop a quantitative spatial model with heterogeneous firms and a monopsonistic labour market to derive minimum wages that maximize employment or welfare. Quantifying the model for German micro regions, we find that the German minimum wage, set at 48% of the national mean wage, has increased aggregate worker welfare by about 2.1% at the cost or reducing employment by about 0.3%. The welfare-maximizing ...

Social Norms and Preventive Behaviors in Japan and Germany During the COVID-19 Pandemic

Background: According to a recent paper by Gelfand et al., COVID-19 infection and case mortality rates are closely connected to the strength of social norms: “Tighter” cultures that abide by strict social norms are more successful in combating the pandemic than “looser” cultures that are more permissive. However, countries with similar levels of cultural tightness exhibit big differences in mortality ...

The personality traits of self-made and inherited millionaires

Very wealthy people influence political and societal processes by wielding their economic power through foundations, lobbying groups, media campaigns, as investors and employers. Because personality shapes goals, attitudes, and behaviour, it is important to understand the personality traits that characterize the rich. We used representative survey data to construct two large samples, one from the general ...
