We study the relation between workers’ age and their productivity in work teams, based on a new and unique data set that combines data on errors occurring in the production process of a large car manufacturer with detailed information on the personal characteristics of workers re-lated to the...

We test whether immigrants are more prone to support terror than natives because of lower opportunity costs, using the international World Values Survey data. We show that, in general, economically, politically and socially non-integrated persons are more likely to accept using violence for...

This contribution studies the influence of poor politico-economic factors, unfavorable demographic conditions, state failure, modernization, secularization, globalization and the perceived dependency of the Islamic world from the West on the onset of armed Islamist activity for 155 countries...

This study explores the reduction potential of greenhouse gases for major pollution emitting countries of the world using nonparametric productivity measurement methods and directional distance functions. In contrast to the existing literature we apply optimization methods to endogenously...

Based on the seminal paper of Farrell (1957), researchers have developed several methods for measuring e fficiency. Nowadays, the most prominent representatives are nonparametric data envelopment analysis (DEA) and parametric stochastic frontier analysis (SFA), both introduced in the late 1970s....

Given the ambiguous empirical results of previous research, this paper tests whether support for a climate policy induced pollution haven effect and the pollution haven hypothesis can be found. Unlike the majority of previous studies, the analysis is based on international panel data and...

We consider a monopolistic supplier's optimal choice of wholesale tariffs when downstream firms are privately informed about their retail costs. Under discriminatory pricing, downstream firms that differ in their ex ante distribution of retail costs are offered different tariffs. Under uniform...

We analyze dynamic price competition in a homogeneous goods duopoly, where consumers exchange information via word-of-mouth communication. A fraction of consumers, who do not learn any new information, remain locked-in at their previous supplier in each period. We analyze Markov perfect...

We examine welfare effects of real-time pricing in electricity markets. Before stochastic energy demand is known, competitive retailers contract with final consumers who exogenously do not have real-time meters. After demand is realized, two electricity generators compete in a uniform price...

This paper studies product obsolescence, the entry and exit of firms, and the evolution of firm size as foundation of endogenous economic growth. I develop a dynamic general equilibrium model with heterogenous firms to analyze firm behavior in an economic environment that is characterized by a...
