Self-reported measures of health are generally treated as weak measures of respondents' objective health status. On the other hand, most surveys use self-reported health to measure health status and to determine the effects of a range of other socio-economic characteristics of the local...

The Berlin Aging Study II (BASE-II) is a multidisciplinary study that allows for the investigation of how a multitude of health status factors as well as many other social and economic outcomes interplay. The sample consists of 1,600 participants aged 60 to 80, and 600 participants aged 20 to...

The article analyzes the question of whether career politicians differ systematically from the general population in terms of their attitudes toward risk. A written survey of members of the 17th German Bundestag in late 2011 identified their risk attitudes, and the survey data was set in...

The paper seeks to answer whether career politicians differ systematically from the general population in terms of their attitudes toward risk. A written survey of members of the 17th German Bundestag in late 2011 identified their risk attitudes, and the survey data was set in relation to...

This study presents results of the validation of an ultra-short survey measure of patience included in the German Socio-Economic Panel (SOEP). Survey responses predict intertemporal choice behavior in incentive-compatible decisions in a representative sample of the German adult population.

The results of a resurvey of non-respondents to the SOEP study carried out in 2006 show that this special effort of reinterviewing was relatively ineffective in two respects. First, the rate of successful conversions of passive to active respondents was low (less than 20 percent). Second, the...

Up to now in the social sciences, what is known as citizen science—the involvement of interested citizens in scientific surveys—has been used relatively little as a method of empirical social research. While the “citizens’ dialogues” that are becoming more widespread in politics can be...

Like many medical studies, the Berlin Aging Study II (BASE·II) is based on a non·random "convenience sample" of self·recruited participants. To study processes of selectivity in BASE·II, we used an identical questionnaire to compare BASE·II with a large, representative reference study, the...

Perceived control plays an important role in shaping development throughout adulthood and old age. Using data from the adult lifespan sample of the national German Socio-Economic Panel (SOEP; N 10,000, covering 25 years of measurement), we explored long-term antecedents, correlates, and...

After the introduction in Section 2, we very briefly sketch out current theoretical and empirical developments in the social sciences. In our view, they all point in the same direction: toward the acute and increasing need for multidisciplinary longitudinal data covering a wide range of living...
