We investigate the dimensions through which R&D spillovers are propagated across firms via cooperation through Research Joint Ventures (RJVs). We build on the framework developed by Bloom et al. (2013) which considers the opposing effects of technology spillovers and product market rivalry, and extend it to account for RJVs. Our main findings are that the adverse effects of product market rivalry are ...
Vor fünf Jahren erreichte die Fluchtzuwanderung nach Deutschland ihren Höhepunkt. Bei der Integration von nach Deutschland Geflüchteten wurde bereits viel erreicht. Das DIW Berlin blickt auf Grundlage eigener Datenerhebungen auf die bislang erzielten Erfolge und weiter bestehende Herausforderungen: Welche Erwartungen hatten Geflüchtete an ihre Erwerbstätigkeit und haben...
In line with the Social Investment Principle, becoming a parent should lead to more mature behavior and an increase in conscientiousness, agreeableness, and emotional stability. However, previous research provided mixed results that do not support this idea. Here, we used data from a nationally representative household panel study from Germany (N = 19,875) to examine whether becoming a parent relates ...

At the same time, our experiences in these relationships may affect our personality. Who experiences specific major relationship events and how do these events relate to personality development? We examined this issue based on data from a nationally representative household ...
This study develops and applies a framework for analyzing variability in individuals’ occupational prestige trajectories and changes in average variability between birth cohorts. It extends previous literature focused on typical patterns of intragenerational mobility over the life course to more fully examine intracohort differentiation. Analyses are based on rich life course data for men and women ...
Gerechtigkeit beschäftigt die Menschheit seit sehr langer Zeit. Erste Abhandlungen dazu finden sich bereits in der Zeit der frühen Hochkulturen des 2. Jahrtausends vor der christlichen Zeitrechnung. Darin wird sie als eine menschliche Tugend beschrieben, die darin begründet ist, dass sich Menschen gegenseitig etwas schulden und den Mächtigen nicht alles erlaubt sei. So lässt etwa Platon Sokrates sagen: ...
There is ample empirical literature centering on the effectiveness of foreign exchange intervention (FXI). Given the mix of objectives and country-heterogeneity, the general lack of consensus thus far is no surprise. We shed light on this debate by conducting the first comprehensive meta-analysis in the FXI literature, with 279 reported effects that stem from 74 distinct empirical studies. We cover ...
In this paper, we analyze the interdependence between the structure of transmission infrastructure and the electricity mix, applied to the case of Germany today and into the future. In particular, we are interested in how an energy system based on a high share of distributed renewable sources operates under different transmission regimes, for example, copper plate or more constrained network topologies. ...
