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 ...

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 ...

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 ...

Does Subsidizing Investments in Energy Efficiency Reduce Energy Consumption? Evidence from Germany

Improving energy efficiency is one of the three pillars of the European energy and climate targets for 2020 and has led to the introduction of several policy measures to promote energy efficiency. The paper analyzes the effectiveness of subsidies in increasing energy efficiency in residential dwellings. An empirical analysis is conducted in which the effectiveness of subsidies on the number of dwelling ...

Endogenous Investment Decisions in Natural Gas Equilibrium Models with Logarithmic Cost Functions

The liberalisation of the natural gas markets and the importance of natural gas as a transition fuel to a low-carbon economy have led to the development of several large-scale equilibrium models in the last decade. These models combine long-term market equilibria and investments in infrastructure while accounting for market power by certain suppliers. They are widely used to simulate market outcomes ...

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 ...

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 ...
