Report of the High-Level Commission on Carbon Prices I MAY 29, 2017 Report of the High-Level Commission on Carbon Prices I MAY 29, 2017 Report of the High-Level Commission on Carbon Prices supported by: MINISTÈRE DE LA TRANSITION ÉCOLOGIQUE ET SOLIDAIRE THE COMMISSION: 6OBJECTIVES During the 22nd Conference of the Parties (COP) of the United Nations Framework Convention on Climate Change (UNFCCC) held in Marrakech, Morocco, in 2016, at the invitation of the Co- Chairs of the Carbon Pricing Leadership Coalition (CPLC) High-Level Assembly, Ségolène Royal and Feike Sijbesma, Joseph Stiglitz, Nobel Laureate in Economics, and Lord Nicholas Stern, accepted to chair a new High-Level Commission on Carbon Prices comprising economists, and climate change and energy specialists from all over the world, to help spur successful implementation of the Paris Agreement. The Commission’s objective is to identify indicative corridors of carbon prices that can be used to guide the design of carbon-pricing instruments and other climate policies, regulations, and measures to incentivize bold climate action and stimulate learning and innovation to deliver on the ambition of the Paris Agreement and support the achievement of the Sustainable Development Goals.

This report does not focus on the estimation and evaluation of the climate change impacts that would be avoided by reducing carbon emissions. While the Commission also covers other policies relevant and important to carbon-pricing design and delivery on the Paris agreement, its primary focus is on pricing. This report has been prepared based on the Commission’s assessment of the available evidence

Based on the analyses in which land is used as a factor of production, we can confirm that the taxation of land will lead to an increase in the growth rate of the economy. Particularly, we show that the introduction of a tax on land rents, a tax on the value of land or a stamp duty will cause the net price of land to decline. Further, we show that the nationalization of land and the redistribution of the land rents to the young generation will maximize the growth rate of the economy.

  • Hypergeorgism: When Rent Taxation Is Socially Optimal∗
    Hypergeorgism: When rent taxation is socially optimal∗ Ottmar Edenhoferyz, Linus Mattauch,x Jan Siegmeier{ June 25, 2014 Abstract Imperfect altruism between generations may lead to insufficient capital accumulation. We study the welfare consequences of taxing the rent on a fixed production factor, such as land, in combination with age-dependent redistributions as a remedy. Taxing rent enhances welfare by increasing capital investment. This holds for any tax rate and recycling of the tax revenues except for combinations of high taxes and strongly redistributive recycling. We prove that specific forms of recycling the land rent tax - a transfer directed at fundless newborns or a capital subsidy - allow reproducing the social optimum under pa- rameter restrictions valid for most economies.

Electricity prices vary dramatically between moments in time, between location, and according to lead-time between contract and delivery. This three-dimensional het- erogeneity has implication for the economic assessment of power generation technologies: differ- ent technologies, such as coal-fired plants and wind turbines, produce electricity that has, on av- erage, a different economic value. Several tools that are used to evaluate generators in practice ignore these value differences, including “levelized electricity costs”, “grid parity”, and simple macroeconomic models.

The replacement of the business tax with the value- added tax led to increased demand for firms in service industries. Using a sample of listed firms during the period 2009-2017, we show that affected firms increased their R&D investment significantly as a response to improved demand conditions, relative to firms that were not subject to the policy reform.

He is Director and Chief Economist at the Potsdam Institute for Climate Impact Research (PIK). From 2007 to 2018 he headed PIK’s Research Domain 3 Sustainable Solutions, which received an excellent evaluation by the Leibniz Society in 2014. Following the strategic decision of PIK in 2007 to become more solution-oriented with interdisciplinary Research Domains, Ottmar Edenhofer formed the research agenda of this department. He was pioneering in giving the institute, which traditionally focused on large-scale quantitative computational modelling of the earth and its processes, a social science research agenda providing rigorous and meaningful information on climate change mitigation to society. In 2012 he was appointed director of the newly founded Mercator Research Institute on Global Commons and Climate Change (MCC). The work of the MCC was considered “excellent” by an external scientific evaluation board commissioned by Stiftung Mercator in 2015.

  • Carbon Pricing and Transfers : Feasible and Effective Multilevel Climate
    Carbon Pricing and Transfers Feasible and Effective Multilevel Climate Policy in Federations vorgelegt von Christina Roolfs Master of Sustainability Economics and Management ORCID: 0000-0001-7731-193X an der Fakultät VI - Planen Bauen Umwelt der Technischen Universität Berlin zur Erlangung des akademischen Grades Doktorin der Wirtschaftswissenschaften - Dr. rer. oec. - genehmigte Dissertation Promotionsausschuss: Vorsitzender: Prof. Dr. Stefan Heiland Gutachter: Prof. Dr. Ottmar Edenhofer Gutachter: Prof. Dr. Marco Runkel Gutachter: Prof. Dr. Matthias Kalkuhl Tag der wissenschaftlichen Aussprache: 16. November 2020 Berlin 2021 Abstract Regional and national governments face the challenge of enacting policies that rapidly decarbonize their economies so as to deliver on their climate targets. They need to fnd policy instruments that are both efective and feasible. Simultaneously reducing greenhouse gas emissions at multiple levels is a promising step forward. By analyzing the efectiveness and feasibility of multilevel climate policies in federal systems, this thesis translates Elinor Ostrom’s polycentric governance approach to formal public economics. General equilibrium models of low to medium complexity are developed and solved analytically and numerically for this purpose. The European Union (EU) serves as the primary example. In a nutshell, the following three results are generated: First, socially optimal transfers imply rich states being donors and poor states being recipients of carbon price revenues. From the perspective of rich states, these transfers may be too large and thus become politically infeasible. Second, choosing a uniform federal carbon price that maximizes the utility of the richest state leads to a minimum federal carbon price to which all member states would agree. The existence of such a minimum federal price depends on the degree of wealth heterogeneity among member states; the federal transfer rules; and whether or not states anticipate federal transfers.

  • Facing the Economic and Institutional Challenges
    3 Beyond the 2°C limit: Facing the economic and institutional challenges Ottmar Edenhofer, Susanne Kadner, Christoph von Stechow and Jan Minx Mercator Research Institute on Global Commons and Climate Change (MCC), Potsdam Institute for Climate Impact Research (PIK) and Technische Universität Berlin; PIK; MCC, PIK and Technische Universität Berlin; MCC, PIK and Hertie School of Governance With very high risk of severe, widespread and irreversible impacts globally due to unabated anthropogenic climate change, we argue in this chapter that the 2°C limit can be justified by the synthesis of available scientific evidence as an application of the precautionary principle. In principle, the risks of mitigation differ fundamentally from the risks of climate change in terms of their nature, timescale, magnitude and persistence. Humankind has the technological means to solve the problem. However, the challenges of stringent mitigation action are enormous and have been increasing over the last decade because of the ongoing renaissance of coal, which does not allow for a decoupling of economic and population growth from emissions. Keeping a greater than 66% probability of staying below the 2°C limit, for example, would require current emission levels to be reduced by 40-70% by 2050, and emission levels of zero and below by the end of the 21st century. This requires a large-scale transformation in the way we produce and use energy, as well as how we use land. The most fundamental challenges are the oversupply of fossil fuels and the risks associated with negative emissions technologies, or high bioenergy deployment. A further delay in mitigation action substantially increases the difficulty of, and narrows the options for, this transformation.
