Considerations on the optimal approach for managing spectrum are currently at the forefront of the debate around the 5925-7125 MHz frequency range (the '6 GHz band'), as Governments decide how best to manage this spectrum over the coming decades. We apply a cost-benefit analysis, using a supply...

We study a matching model with heterogenous agents, nontransferable utility and search frictions. Agents differ along a continuous horizontal dimension (e.g. taste) and a discrete vertical dimension, e.g. income. All individuals prefer the highest type along the vertical trait, but have...

The introduction of the hospital reimbursement based on diagnosis related groups (DRG) in 2004 has been a conspicuous attempt to increase hospital efficiency in Germany. We analyze possible determinants of hospital performance before and after the DRG introduction. A two-stage semi-parametric...

We develop a model to analyze the determinants and effects of an endogenous imperfect transferability of human capital on natives and immigrants. The model reveals that high migration flows and high skill-transferability are mutually interdependent. Moreover, we show that high mobility within a...

Individual OECD countries are in the process of legislating responses to the challenges posed by climate change. The prospect of rising carbon prices raises concerns in these nations of the impacts on the competitiveness of their own energy intensive industries and the potential for carbon...

Is welfare economics still possible, when preferences are endogenously determined? The answer is yes, if and only if the hypothesis of adaptive preferences is correct. If preferences satisfy the conditions of continuity, non-satiation and regularity, then adaptive preferences imply that...

Living downtown has advantages because it allows for a convenient access to a variety of shopping and leisure activities as well as disadvantages due to the difficulties in finding a parking spot when parking capacity is scarce. We formally model the trade-off in a vibrant city district between...

In many empirical Contingent Valuation studies one finds that household size, i. e. the number auf household members, is negatively correlated with stated household willingness to pay for the realization of environmental projects. This observation is rather puzzling because in larger households...

Economic models of climate policy (or policies to combat other environmental problems) typically neglect psychological adaptation to changing life circumstances. People may adapt or become more sensitive, to different degrees, to a deteriorated environment. The present paper addresses these...

Commercial ceilings not only restrict broadcasters in their decisions about commercial broadcasting time, but also affect their differentiation of program content. This study examines the welfare effects of commercial ceilings in a two-sided free-to-air TV market, taking into account welfare...
