We investigate the competitive effects of the merger between Delta Air Lines and Northwest Airlines (2009) in the domestic U.S. airline industry. Applying fixed effects regression models we find that the transaction led to short term price increases of about 11 percent on overlapping routes and...

We examine the issue of market foreclosure by airline partnerships with antitrust immunity. Overlapping data on frequency of service and passenger volumes on non-stop transatlantic routes with information on the dynamics of airline partnerships, we find evidence consistent with the airlines...

The assessment of climate change mitigation policies through economic modeling depends crucially on assumptions under which technological change has been incorporated in the model. Earlier climate-energy-economics modeling attempts heavily relied on the assumption of exogenous technological...

The paper studies the power of educational investments in relation to transfers for fostering lifetime income and for reducing income inequality in Germany. The welfare analysis is based on a model of age-dependent human capital accumulation, featuring dynamic complementarities in skill...

Many countries, especially in Europe, have ambitious goals to transform their national energy systems towards renewable energies. Technological change in both renewable production and efficient use of energy can help to make these targets come true. Using a panel of German firms linked to the...

We examine the incidence and extent of co-authorship and intellectual collaboration in the leading journal of environmental and resource economics: the Journal of Environmental Economics and Management. Previous studies of general economic journals have offered empirical evidence for the fact...

Motivated by the current discussion on different separate banking systems, we provide an overview of the different systems, question them and outline their effect on systemic stability and the German banking sector. The results show that the various separate banking systems only play a minor...

International shipping is an important emitter of greenhouse gases. The International Maritime Organization (IMO) is discussing different approaches to reduce maritime CO2 emissions, in particular market-based mechanisms. In this paper, we assess potential implications of a maritime emission...

We empirically investigate the determinants of self-reporting under the European corporate leniency program. Applying a data set consisting of 442 firm groups that participated in 76 cartels decided by the European Commission between 2000 and 2011, we find that the probability of a firm becoming...

There remains considerable scholarly debate about the role that prior entrepreneurial experience plays in new venture survival. Drawing on entrepreneurial learning theories, we use panel data on 8,400 new ventures to investigate the impact of four different types of prior entrepreneurial...
