To design effective and commonly accepted public health policies against performance-enhancing drugs (PED), it is important to understand general population attitudes. This article elicits PED attitudes in the Berlin population and compares response rates of former athletes (N = 496) with those of non-athletes (N = 1686). In addition, exploiting the natural experiment of the division of Germany, by ...

Can risk-taking propensity be thought of as a trait that captures individual differences across domains, measures, and time? Studying stability in risk-taking propensities across the life span can help to answer such questions by uncovering parallel, or divergent, trajectories across domains and measures. We contribute to this effort by using data from respondents aged 18 to 85 in the German Socio-Economic ...

Well-being development at the end of life is often characterized by steep deteriorations, but individual differences in these terminal declines are substantial and not yet well understood. This study moved beyond typical consideration of health predictors and explored the role of social orientation and engagement. To do so, we used social variables at the behavioral level (self-ratings of social participation) ...

Long-run restrictions have been used extensively for identifying structural shocks in vector autoregressive (VAR) analysis. Such restrictions are typically just-identifying but can be checked by utilizing changes in volatility. This paper reviews and contrasts the volatility models that have been used for this purpose. Three main approaches have been used, exogenously generated changes in the unconditional ...

The actions by the European Central Bank (ECB) during the global and European crises have triggered a highly controversial debate, in particular in Germany, about the costs and benefits of the chosen policy path. The article reviews, compares, and evaluates the different arguments made in favor and against ECB policies around three key dimensions—the link of the policy path to price stability, financial ...

We re-examine the common wisdom that cross-border mergers are the most effective merger strategy for firms facing powerful unions. In contrast, we obtain a domestic merger outcome whenever firms are sufficiently heterogeneous (in terms of productive efficiency and product differentiation). A domestic merger unfolds a “wage-unifying” effect which limits the union's ability to extract rents. When products ...

This study analyses the economic developments in Yemen from the 1970s to today in the context of the resource curse hypothesis. After a brief survey of the resource curse literature, using empirical data, historical accounts, and political (economic) analyses, I confirm that post-reunification Yemen suffers from an intense oil curse. The curse is evidenced by low genuine savings rates, oil-dependency, ...

Changes in residual volatility in vector autoregressive (VAR) models can be used for identifying structural shocks in a structural VAR analysis. Testable conditions are given for full identification for the case where the volatility changes can be modelled by a multivariate GARCH process. Formal statistical tests are presented for identification and their small sample properties are investigated via ...

The hypothalamic-pituitary-adrenal (HPA) and hypothalamic-pituitary-gonadal (HPG) axes are typically conceptualized as mutually inhibitory systems; however, previous studies have found evidence for positive within-person associations (i.e., coupling) between cortisol and testosterone. One developmental hypothesis is that positive testosterone-cortisol coupling is unique to the adolescent period and ...

We examine how late-life personality development relates to overall morbidity as well as specific performance-based indicators of physical and cognitive functioning in 1,232 older adults in the Berlin Aging Study II (aged 65-88 years). Latent growth models indicated that, on average, neuroticism and conscientiousness decline over time, whereas extraversion and openness increase and agreeableness remains ...
