Declining response rates have made traditional, probability-based sampling methods more resource-intensive and thus more expensive. Studies of population subgroups are particularly vulnerable to this trend, as smaller group sizes as well as other factors often make these groups "hard-to-reach" or "hard-to-survey". In response, researchers have increasingly relied on network...
Risk preference impacts how people make key life decisions related to health, wealth, and wellbeing. Yet the evolutionary roots of human risk taking behavior remain poorly understood. I will present two studies on risk preferences in chimpanzees, one of our closest living relatives.In the first study, we investigated whether chimpanzees (N=13) differentiate between social...
This study deals with the impact of the 2015 European Refugee Crisis on the ethnic identity of resident migrants in Germany. To derive plausibly causal estimates, I exploit the quasi-experimental setting in Germany, by which refugees are allocated to different counties by state authorities without being able to choose their locations themselves. This study finds that higher...
Humans possess a need for social contact. Satisfaction of this need benefits well-being, whereas deprivation is detrimental. However, how much contact people desire is not universal, and evidence is mixed on individual differences in the association between contact and well-being. This preregistered longitudinal study (N = 190) examined changes in social contact and well-being (life satisfaction, depressivity/anxiety) ...
Luftverschmutzung verursacht hohe ökonomische Kosten durch gesundheitliche Belastungen der AnwohnerInnen, vor allem in städtischen Gebieten. Fahrbeschränkungen in Umweltzonen sollen zur Verbesserung der Luftqualität beitragen. Empirische Analysen in diesem Wochenbericht bestätigen, dass Umweltzonen verkehrsbedingte Luftverschmutzung verringern. Zusätzlich ergeben die Untersuchungen unbeabsichtigte ...
We investigate the relationship between homeownership and life as well as housing satisfaction. Using panel data from Germany, we find that compared to renting, owning a home positively impacts housing satisfaction. Contrarily, we find no significant effects on life satisfaction in the long-term. Analysing short-term effects in an event-study design, we show that both life and housing satisfaction ...
