In response to the growing burden of obesity, public primary prevention programs against obesity have been widely recommended. Several studies estimated the cost effects of diabetes prevention trials for different countries and found that diabetes prevention can be costeffective. Nevertheless, it is still controversial if prevention conducted in more real-world settings and among people with increased ...
In Germany, inequality of net equivalized income increased noticeably in the first half of the new millennium. We aim to identify the main drivers of this rise in income inequality since the early 1990s. We provide a broad overview of the circumstances under which inequality evolved, i.e. which changes in the German economy are most likely to provide an explanation for changes in income concentration. ...
We investigate whether non-cognitive skills - in particular Locus of Control - are important determinants of the labour market processes at the low-wage margin. Based on data from the German Socio-Economic Panel, we estimate dynamic multinomial logit models with random effects and investigate whether Locus of Control influences the probability of being higher-paid or low-paid as well as the probability ...
Major nuclear accidents as recently in Fukushima set nuclear power plant security at the top of the public agenda. Using data of the German Socio-Economic Panel we analyze the effects of the Fukushima accident and a subsequent government decision on nuclear power phase-out on several measures of subjective perception in Germany. In the light of current political debates about the strategic orientation ...
Despite numerous studies on skill development, we know little about the causal effects of music training on cognitive and non-cognitive skills. This study examines how long-term music training during childhood and youth affects the development of cognitive skills, school grades, personality, time use and ambition using representative data from the German Socio-Economic Panel (SOEP). Our findings suggest ...
We examine the effects of future renewable expansion in Germany on residual load and renewable surplus generation for policy-relevant scenarios for 2022, 2032 and 2050. We also determine the storage capacities required for taking up renewable surpluses for varying levels of accepted curtailment. Making use of extensive sensitivity analyses, our simulations show that the expansion of variable renewables ...
The Chinese model for economic growth is further transforming. While the rise in output was heavily based on investment and export activities in recent decades, private consumption is expected to become a driver for growth in the period ahead. However, the conditions for higher consumer demand of private households are not optimal: The savings rate is high, particularly driven by the low level of social ...
On October 1/2, the DIW Graduate Center welcomed its new cohort through various events. Fifteen promising young students introduced themselves at the welcome reception in the evening of October 1, following the opening speeches of Prof. Marcel Fratzscher, president of DIW Berlin, and Prof. Helmut Lütkepohl, Dean of the GC. On October 2, a detailed introduction to the doctoral program structure ...
Sign restrictions have become increasingly popular for identifying shocks in structural vector autoregressive (SVAR) models. So far there are no techniques for validating the shocks identified via such restrictions. Although in an ideal setting the sign restrictions specify shocks of interest, sign restrictions may be invalidated by measurement errors, data adjustments or omitted variables. We model ...
