We report experimental results from Ghana, where treated subjects received information on regional income differentials. We do not see an effect on migration intentions directly after the intervention, but the effect of the treatment unfolds over time. Eighteen months later, subjects assigned to receive income information are on average significantly less likely to express enthusiasm for moving to ...

Preterm birth has been linked with postpartum depressive (PPD) disorders and high symptom levels, but evidence remains conflicting and limited in quality. It remains unclear whether PPD symptoms of mothers with preterm babies were already elevated before childbirth, and whether PPD symptoms mediate/aggravate the effect of preterm birth on child mental disorders. We examined whether preterm birth associated ...

Despite high inflation, the real gross hourly wages of employees grew by around 15 percent from 1995 to 2022. In particular, the lowest wage decile caught back up to all other deciles following a sharp drop in real wages. At the same time, the low-wage sector has shrunk by nearly five percentage points since 2007, and by even more in the east of Germany (14 percent). In 2022, 18.5 percent of employees ...

The number of employed persons in Germany has grown by over five million since 2000, in part due to an increase in immigration. This development is reflected in private household income, which has increased by 12 percent over the same period. Since 2013, all income groups have been benefiting from this increase and in 2015, the lowest income decile began benefiting as well. Disposable income inequality ...

This study theorizes that the relationship between social trust and governmental quality is reciprocal. Examining the relationship in one direction, we utilize socioeconomic conditions as a performance measure of governmental quality and assess their impact on social trust. Going in the other direction, we examine the effects of social trust on political behavior as a determinant of governmental quality. ...

Subjective well-being is essential for both quality of life and a healthy society. Studies have shown that satisfied people have better relationships, are more productive, and have a longer life expectancy. General life satisfaction is being discussed as an alternative measure of prosperity beyond GDP. Thus, findings on this topic are relevant for both the scientific community as well as policymakers. ...

For many people, parenthood constitutes a crucial part of a successful life. Yet, the number of adults who never have children is increasing and has prompted concerns about their well-being. Past research mostly focused on parents and rarely investigated factors that are theoretically meaningful for the well-being of adults without children. Our preregistered study uses a propensity-score matched design ...
