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 evaluates whether the trajectories of forced migrants, specifically Syrian refugees moving towards Germany, exhibit path dependency—meaning that their migration decisions are influenced by past events and their previous migration experiences. Using data from the IAB-BAMF-SOEP survey of refugees, this article investigates whether these migration trajectories adhere to a Markov process, where ...
