Inequality, Inequity Aversion, and the Provision of Public Goods
Kölle, Felix; Sliwka, Dirk; Zhou, Nannan - Institute for the Study of Labor (IZA) - 2011
We investigate the effects of inequality in wealth on the incentives to contribute to a public good when agents are inequity averse and may differ in ability. We show that equality may lead to a reduction of public good provision below levels generated by purely selfish agents. But introducing...

Unobservable, but Unimportant? The Influence of Personality Traits (and Other Usually Unobserved Variables) for the Evaluation of Labor Market Policies
Caliendo, Marco; Mahlstedt, Robert; Mitnik, Oscar A. - Institute for the Study of Labor (IZA) - 2014
Many commonly used treatment effects estimators rely on the unconfoundedness assumption ("selection on observables") which is fundamentally non-testable. When evaluating the effects of labor market policies, researchers need to observe variables that affect both treatment participation and labor...

Dynamic Incentive Effects of Heterogeneity in Multi-Stage Promotion Contests
Stracke, Rudi; Sunde, Uwe - Institute for the Study of Labor (IZA) - 2014
This paper shows that the incentive effects of heterogeneity may be positive rather than negative in dynamic contests … with multiple stages. In particular, the well-studied adverse effects of heterogeneity in static interactions are … compensated by positive continuation-value and selection effects. Due to these positive dynamic incentive effects of heterogeneity …

Causal Returns to Schooling and Individual Heterogeneity
Pfeiffer, Friedhelm; Pohlmeier, Winfried - Institute for the Study of Labor (IZA) - 2012
In this paper, human capital investments are evaluated by assuming heterogeneous returns to schooling. We use the potential outcome approach to measure the causal effect of human capital investments on earnings as a continuous treatment effect. Empirical evidence is based on a sample of West...

The Life-Cycle and the Business-Cycle of Wage Risk: A Cross-Country Comparison
Bayer, Christian; Juessen, Falko - Institute for the Study of Labor (IZA) - 2009
This paper provides a cross-country comparison of life-cycle and business-cycle fluctuations in the dispersion of household-level wage innovations. We draw our inference from household panel data sets for the US, the UK, and Germany. First, we find that household characteristics explain about...

Repeated Selection with Heterogenous Individuals and Relative Age Effects
Dawid, Herbert; Muehlheusser, Gerd - Institute for the Study of Labor (IZA) - 2012
In contexts such as education and sports, skill-accumulation of individuals over time crucially depends on the amount of training they receive, which is often allocated on the basis of repeated selection. We analyze optimal selection policies in a model of endogenous skill formation where, apart...
