Cohort Differences in Psychosocial Function over 20 Years: Current Older Adults Feel Less Lonely and Less Dependent on External Circumstances

Background: Lifespan psychological and life course sociological perspectives indicate that individual development is shaped by social and historical circumstances. Increases in fluid cognitive performance over the last century are well documented and researchers have begun examining historical trends in personality and subjective well-being in old age. Relatively less is known about secular changes ...

Inevitable? Doping Attitudes among Berliners in 2011: The Role of Socialist State Socialisation and Athlete Experience

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 ...

Stability and Change in Risk-Taking Propensity across the Adult Life Span

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 ...

Terminal Decline in Well-Being: The Role of Social Orientation

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) ...

Structural Vector Autoregressions: Checking Identifying Long-Run Restrictions via Heteroskedasticity

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 ...

Rules versus Human Beings, and the Mandate of the ECB

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 ...

How to Counter Union Power? Equilibrium Mergers in International Oligopoly

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 ...

Resource Curse Contagion in the Case of Yemen

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, ...

Testing for Identification in SVAR-Garch Models

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 ...
