Interconnection and Prioritization

We analyze pricing and competition under paid prioritization within a model of interconnected internet service providers (ISPs), heterogeneous content providers (CPs) and heterogeneous consumers. We show that prioritization is welfare superior to a regime without prioritization (network neutrality) and yields higher incentives for investment in network capacities. As ISPs price discriminate between ...

A Note on Networks of Collaboration in Multi-market Oligopolies

In this note, we extend the Goyal and Joshi’s model of collaboration networks in oligopoly to multi-market situations. We examine the incentive of firms to form links and the architectures of the resulting equilibrium networks in this setting. We then present some results on efficient networks.

Market Power Rents and Climate Change Mitigation: A Rationale for Coal Taxes?

In this paper we investigate the introduction of an export tax on steam coal levied by an individual country (Australia), or a group of major exporting countries. The policy motivation would be twofold: generating tax revenues against the background of improved terms-of-trade, while CO2 emissions are reduced. We construct and numerically apply a two-level game consisting of an optimal policy problem ...

Ergänzung des Emissionshandels: Anreize für einen klimafreundlicheren Verbrauch emissionsintensiver Grundstoffe

Die Produktion emissionsintensiver Grundstoffe wie Stahl, Aluminium und Zement ist für einen Großteil der CO2-Emissionen der europäischen Industrie verantwortlich. Da die Hersteller dieser Grundstoffe im internationalen Wettbewerb stehen und das CO2-Preissignal nur zu einem geringen Teil weitergeben können, gibt das europäische Emissionshandelssystem (EU ETS) bisher für viele Emissionsminderungsoptionen ...

Heterogeneity in Price Responsiveness for Residential Space Heating in Germany

Space heating and hot water expenditures make up the majority of household energy demand in Germany, at 83.2%, making them an attractive target for energy policies. Using a panel dataset derived from yearly residential household surveys covering the years 1996 to 2014, we identify the determinants of heating expenditures for German households. We discover significant heterogeneity in expenditures depending ...

Trade and Climate Policies: The Role of Market Structure, Strategic Behaviour, and the Supply Side of Carbon ; Dissertation

Als globales Problem ist der Klimawandel eine der größten Herausforderungen der heutigen Zeit und muss im Kontext einer zunehmenden Globalisierung verstanden werden. Die vorliegende Dissertation untersucht die Zusammenhänge zwischen internationalem Handel und Klimapolitik und leistet einen Beitrag zum wissenschaftlichen Diskurs, indem sie diese aus zwei unterschiedlichen Perspektiven betrachtet: zum ...

Sowing the Wind and Reaping the Whirlwind? The Effect of Wind Turbines on Residential Well-Being

We investigate the effect of the physical presence of wind turbines on residential well-being in Germany, using panel data from the German Socio-Economic Panel (SOEP) and a unique novel panel data set on more than 20,000 wind turbines for the time period between 2000 and 2012. Using a Geographical Information System (GIS), we calculate the proximity between households and the nearest wind turbine as ...

Market Power, Fuel Substitution and Infrastructure: A Large-Scale Equilibrium Model of Global Energy Markets

Assessing and quantifying the impacts of technological, economic, and policy shifts in the global energy system require large-scale numerical models. We propose a dynamic multi-fuel market equilibrium model that combines endogenous fuel substitution within demand sectors and in power generation, detailed infrastructure capacity constraints and investment, as well as strategic behaviour and market power ...
