The transition towards decarbonized energy systems requires the expansion of renewable and flexibility technologies in power sectors. Many powerful tools exist to find optimal capacity expansion. In a stylized comparison of six models, we evaluate the capacity expansion results of basic power sector technologies. The technologies under investigation include base- and peak load power plants, electricity ...
Wenn der Mindestlohn steigt, muss auch die Geringfügigkeitsgrenze bei Minijobs steigen. Doch damit werden Minijobs ausgeweitet – und das wäre fatal für den Arbeitsmarkt. Die Vorhaben der neuen Regierung für Arbeitsmarktreformen und Sozialsystem sind ambitioniert und gleichzeitig ausgewogen. Bis auf eine große Schwäche: die Pläne bei den Minijobs. Dieser ...

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...
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...
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) ...
