Die Gasversorgung ist in diesem Winter gesichert, aber Deutschland hat viele Fehler gemacht

Die Zuspitzung der Ukraine-Krise könnte auch Auswirkungen auf die russischen Gaslieferungen an Deutschland haben. Ob es dadurch zu Energie-Engpässen kommen könnte und welche Auswirkungen es auf die Gaspreise hätte, kommentiert Claudia Kemfert, Leiterin der Abteilung Energie, Verkehr, Umwelt am Deutschen Institut für Wirtschaftsforschung (DIW Berlin):

DIW Konjunkturbarometer Januar: Omikron-Welle bremst deutsche Wirtschaft zum Jahresauftakt aus

Das Konjunkturbarometer des Deutschen Instituts für Wirtschaftsforschung (DIW Berlin) gibt im Januar leicht nach. Nachdem es im vierten Quartal 2021 noch knapp über der 100-Punkte-Schwelle lag, ist es mit einem Indexstand von 99,5 Punkten für das erste Quartal 2022 nun darunter gefallen. Die Wirtschaftsleistung dürfte in Deutschland bereits im Schlussquartal etwas nachgegeben haben ...

The Effects of Shortening Potential Benefit Duration: Evidence from Regional Cut-offs and a Policy Reform

We quantify labour market effects of changes in the potential benefit duration (PBD) in Poland. Individual workers' PBD depends on the county unemployment rate relative to the national average---12 months of PBD above a cut-off of 125 per cent and 6 months below. This cut-off shifted from 125 to 150 per cent in a 2009 reform. We utilize (i) the natural experiment of the reform and (ii) the...

A decomposition of the life-cycle part-time wage gap: Forgone promotion prospects and stagnant wage growth within job levels

Long periods of part-time work lead to a stagnation of wage growth. In this paper, I study how the wage stagnation decomposes in lack of career development and the lack of wage growth conditional on the career level. I develop a dynamic choice model of labor supply which distinctly incorporates vertical career moves to jobs paying higher wages as a function of the choice of hours of work. I...

Promotion prospects and within-level wage growth: A decomposition of the part-time penalty

The part-time wage penalty is a key contributor to the gender wage gap. In this paper, I study how the part-time penalty decomposes in a lack of promotions to higher paying levels of the career ladder and a lack of wage growth conditional on the career level. I develop a dynamic model of labor supply that distinctly features hierarchical wage structures and promotions. I estimate the...

Warheads of Energy: Exploring the Linkages between Civilian Nuclear Power and Nuclear Weapons in Seven Countries

This paper focuses on the causal determinants of the accumulation of nuclear weapons, also known as vertical nuclear proliferation, in China, France, India, Pakistan, Russia, UK, and the US. It empirically analyzes the causal relationships between the civilian uses of nuclear energy, military expenditures, trade openness, and the stockpiling of nuclear warheads. Results from the Toda and Yamamoto (1995) ...

Center-Based Care and Parenting Activities

We examine the relationship between parenting activities and center-based care using time diary and survey data for mothers in Germany. While mothers using center-based care spend significantly less time in the presence of their child, we find that differences in the time spent on specific activities such as reading, talking, and playing with the child are relatively small or zero. The pattern of results ...

The Development of the Rank-Order Stability of the Big Five across the Life Span

Several studies have suggested that the rank-order stability of personality increases until midlife and declines later in old age. However, this inverted U-shaped pattern has not consistently emerged in previous research; in particular, a recent investigation implementing several methodological advances failed to support it. To resolve the matter, we analyzed data from two representative panel studies ...
