Policy-makers face a trade-off between the provision of higher levels of schooling and earlier labour market entries. A fundamental education reform in Germany tackles this trade-off by reducing high school by one year while leaving the total instructional time unchanged. Employing...

Excessive alcohol consumption among young people is a major public health concern. On March 1, 2010, the German state of Baden-Württemberg banned the sale of alcoholic beverages between 10pm and 5am at off-premise outlets (e.g., gas stations, kiosks, supermarkets). We use rich monthly...

To counteract the financial pressure emerging in aging societies, statutory pay-as-you-go pension schemes are undergoing fundamental reforms in many Western countries. Starting with cohort 1937, Germany introduced permanent pension deductions for early retirement. This paper examines the...

Gazprom, the dominant gas company in Russia, is widely believed to be the key supplier of gas to Europe in the foreseeable future. However, there are numerous uncertainties and challenges within the Russian and European gas industry that may alter the allocation of Gazprom´s gas sales between...

We study the performance of different regulatory approaches for the expansion of electricity transmission networks in the light of realistic demand patterns and fluctuating wind power. In particular, we are interested in the relative performance of a combined merchant-regulatory mechanism...

This paper analyzes the welfare implications of buyer mergers, which are mergers between downstream firms from different markets. We focus on the interaction between the merger's effects on downstream efficiency and on buyer power in a setup where one manufacturer with a non-linear cost function...

We analyze the dynamic effect of prices and price volatility on current oil production, both on the level of country groups and the major individual producer countries. A comprehensive dataset at monthly frequency allows us to include a rich lag structure while controlling for key global and...

This paper shows that the welfare dominance of ad valorem over unit taxes under imperfect competition, extends to the Dixit-Stiglitz framework with differentiated products, entry and love of variety. This contrasts against findings by Anderson et al. (J Public Econ, 2001) made in a similar...

The objective of this paper is to develop a model to determine the price formation of wholesale electricity markets. For that purpose, we model wholesale electricity prices depending on the prices of fuels (coal and natural gas) and of CO2 emission allowances using a Markov Switching Regression....

We analyze duopoly Bertrand competition under network effects. We consider both incompatible and compatible products. Our main result is that network effects create a fundamental conflict between the maximization of social welfare and consumer surplus whenever products are incompatible. While...
