Empirical evidence suggests that many mergers do not increase profits of the participating firms and decrease welfare. Due to the globalization of markets we should take an international view on mergers and their welfare effects. This paper develops a Bertrand-model of an international...

Individual labour productivities are often unobservable for firms when hiring new workers. Job protection may prevent firms ex post from using information about labour productivities. We show that a binding minimum wage introduced in the presence of job protection will lead to lower unemployment...

In certain circumstances, both researchers and policy makers are faced with the challenge of determining individual efficiency scores for each decision making unit (DMU) under consideration. In this study, we use a Monte Carlo experimentation to analyze the optimal approach to determining...

It is common knowledge that Next Generation Access (NGA) networks require significant investments and that for many regions, especially in more rural areas, there is no viable business case. Taking note of the broadband strategies formulated by European governments the deployment cost is...

The literature on vertical integration in markets with regulated upstream prices suggests that the integrated upstream firm might engage in non-price discrimination. Several studies provide policy recommendations derived either from case study approaches or based on theoretical modeling which...

Climate protection is a global challenge that all countries have a common but differentiated responsibility to address. However, not all governments are willing to commit to targets of equal stringency, and individual countries may put different emphases on carbon pricing in their policy mix....

Klimaschutz ist eine globale Herausforderung, für deren Bewältigung alle Länder eine gemeinsame, aber differenzierte Verantwortung tragen. Einzelne Länder setzen in ihrem Politikmix jedoch unterschiedlich stark auf die Bepreisung von CO2, so dass sich die CO2-Preise in verschiedenen Ländern...

The joint evolution of participating and complying firms in a public VA, along with the evolution of the pollution stock is examined. Replicator dynamics modeling participation and compliance are combined with pollution stock dynamics. Fast-slow selection dynamics are used to capture the fact...

Short-term auctions for access to entry terminals of the British gas-network appear to successfully allocate scarce resources and capture scarcity rent. Now long-term auctions are being introduced to guide future capacity expansion decisions. In our model the fraction of rights issued in the...

This paper discusses the role that finance plays in promoting the capital development of the economy, with particular emphasis on the current situation of the United States and the United Kingdom. We define both "finance" and "capital development" very broadly. We begin with the observation that...
