e discuss the implications of two price zones (i.e., one northern and one southern bidding area) on the German electricity market. In the northern zone, continuous increases in capacity with low variable costs cause large regional supply surpluses in the market dispatch, while in the southern zone conventional capacity decreases. As the spatial imbalance of supply and load is increasing, the current ...

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 ...

This paper explores the long run relationship between public and private investment in the euro area. In contrast to previous studies a stock-flow approach is applied to control for the different orders of integration between the stock and flow variables. Panel econometric techniques allowing for international spillovers are employed. Private and public capital stocks are both I(2) and cointegrated. ...

Theoretical work based on social identity theory predicts that population diversity undermines redistributive public policies. This article tests this proposition exploiting an exogenous shock in diversity due to Germany’s reunification. In contrast to previous work on ethno-linguistic or racial heterogeneity, we specifically analyze religious diversity, which is an increasingly relevant social cleavage ...

Situated at the intersection of the literatures on speculative storage and non-renewable commodity scarcity, this paper considers whether changes in persistence have occurred in long-run U.S. prices of the energy commodities crude oil, natural gas and bituminous coal. We allow for a structural break when testing for a break in persistence to avoid a change in the stochastic properties of prices being ...

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 ...

In recent years, an increasing number of nationally representative surveys in the social sciences and economics have implemented the Big Five model of personality. While many personality inventories were originally developed in the context of self-administered questionnaires, they are often used by large surveys in face-to-face interview settings instead. Drawing on an experimental research design, ...

We analyze the effects of incentive regulation with revenue caps on the investment behaviors of 109 German electricity distribution companies. We hypothesize that with Germany's implementation of incentive regulation in 2009 firms increase their investments in the base year when the rate base is determined for the following regulatory period. We build a model that controls for both firm-specific heterogeneity ...
