We analyze competition between Internet Service Providers (ISPs) where consumers demand heterogeneous content within two Quality-of-Service (QoS) regimes, Net Neutrality and Paid Prioritization, and show that paid prioritization increases the static efficiency compared to a neutral network. We also consider paid prioritization intermediated by Content Delivery Networks (CDNs). While the use of CDNs ...
Die Ukraine erlebt seit zehn Jahren einen wirtschaftlichen Niedergang, der durch internationale Finanzhilfen abgefedert wird. Seit 20 Jahren drängen westliche Geber auf marktwirtschaftliche Reformen im Energiesektor, die von der Ukraine immer wieder verschleppt oder nur halbherzig umgesetzt wurden. So ist das Land nach wie vor die energieintensivste Volkswirtschaft Europas. Seit 2014 haben daran auch ...
Existing long-term energy and climate scenarios are typically a rather simple extrapolation of past trends. Both qualitative and quantitative outlooks co-exist, but they often focus narrowly on individual perspectives, which is opposed to the interlinked and complex nature of energy and climate. Therefore, this study presents a set of novel and multidisciplinary narratives that give insight into four ...
The Trump administration has promised to stop the spiraling down of the U.S. coal industry that has been going on for several years. We discuss the origins of the decline of the U.S. coal industry and new policy interventions by the Trump administration. We find that a further decrease of coal consumption in the U.S. electricity sector must be expected because of the old and inefficient U.S. coal-fired ...
This paper illustrates how many partial equilibrium problems with oligopolistic supply can be cast as convex optimization problems rather than mixed complementarity problems as is the current method of choice in the literature. The convex objective can be constructed by adding an appropriate term to a social welfare maximization objective. Adding this Market Power Adjustment (MPA) term creates a convex ...
With Germany’s nuclear phase-out, 23 reactors need to be dismantled in the near future. Initiated by the dire financial situation of the affected utilities in 2014, a major discourse on ensuring financial liability led to a redistribution of liabilities and finances, with the utilities remaining in charge of dismantling, while liability for interim and final storage now transferred to the public. This ...
Minimum prices above the competitive level can lead to allocative inefficiencies. We investigate whether this effect is more pronounced when decision makers are influenced by their social environment. Using data of minimum prices for renewable energy production in Germany, we test if individual decisions to install photovoltaic systems are affected by the investment decisions of others in the area. ...
