Simulation results show that, given an ambitious greenhouse gas emission constraint and a price of carbon, positive economic effects are possible if (1) technical progress results (partly) endogenously from the model and (2) a policy intervention triggering an increase of investment is introduced.

Until then, climate change had been framed mainly as a problem of negative externalities leading to long-term economic costs, which resulted in countries trying to keep the short-term costs of climate action to a minimum. Carney argued that climate change, as well as climate policy, can also lead to short-term financial risks, potentially causing strong adjustments in asset prices. Analysing the effect of a sustainability transition on the financial sector challenges traditional economic and financial analysis and requires a much deeper understanding of the interrelations between climate policy and financial markets. This dissertation thus investigates the implications of climate policy for financial markets as well as the role of financial markets in a transition to a sustainable economy. The approach combines insights from macroeconomic and financial risk analysis. Following an introduction and classification in Chapter 1, Chapter 2 shows a macroeconomic analysis that combines ambitious climate targets (negative externality) with technological innovation (positive externality), adaptive expectations and an investment program, resulting in overall positive macroeconomic outcomes. The analysis also reveals the limitations of climate economic models in their representation of financial markets. Therefore, the subsequent part of this dissertation is concerned with the link between climate policies and financial markets. In Chapter 3, an empirical analysis of stock-market responses to the announcement of climate policy targets is performed to investigate impacts of climate policy on financial markets. Results show that 1) international climate negotiations have an effect on asset prices and 2) investors increasingly recognize transition risks in carbon-intensive investments. In Chapter 4, an analysis of equity markets and the interbank market shows that transition risks can potentially affect a large part of the equity market and that financial interconnections can amplify negative shocks. In Chapter 5, an analysis of mortgage loans shows how information on climate policy and the energy performance of buildings can be integrated into risk management and reflected in interest rates. While costs of climate action have been explored at great depth, this dissertation offers two main contributions. First, it highlights the importance of a green investment program to strengthen the macroeconomic benefits of climate action. Second, it shows different approaches on how to integrate transition risks and opportunities into financial market analysis. Anticipating potential losses and gains in the value of financial assets as early as possible can make the financial system more resilient to transition risks and can stimulate investments into the decarbonization of the economy. N2 - Mit der Rede "Die Tragödie des Horizonts durchbrechen" im September 2015 hat der Präsident der englischen Zentralbank, Mark Carney, den Klimawandel auf die Agenda der Finanzmarktregulierer gebracht. Bis dahin wurde der Klimawandel vor allem als Problem einer negativen Externalität verstanden, welche langfristige Kosten verursacht. Dies führte dazu, dass sich die meisten Länder darauf konzentrieren, die kurzfristigen Kosten für Klimaschutzmaßnahmen auf ein Minimum zu reduzieren. Carney argumentierte, dass der Klimawandel, sowie Klimapolitik, auch zu kurzfristigen finanziellen Risiken führen kann, welche zu starken Anpassungen der Vermögenspreise führen können. Solche Auswirkungen zu untersuchen, stellt die traditionellen Wirtschafts- und Finanzmodelle jedoch vor Herausforderungen und erfordert ein tiefgreifenderes Verständnis der Zusammenhänge zwischen Klimapolitik und Finanzmärkten. Die vorliegende Arbeit untersucht daher die Auswirkungen der Klimapolitik auf die Finanzmärkte sowie die Rolle der Finanzmärkte in der Transformation zu einer nachhaltigeren Wirtschaft. Der Ansatz kombiniert Erkenntnisse aus der makroökonomischen Modellierung und der finanziellen Risikoanalyse. Nach einer Einführung und Einordnung in Kapitel 1, zeigt Kapitel 2 eine makroökonomische Analyse, welche ehrgeizige Klimaziele (negative Externalität) mit technologischer Innovationen (positive Externalität), adaptiven Erwartungen, sowie einem Investitionsprogramm kombiniert und damit zu positiven makroökonomischen Ergebnissen führt. Die Analyse zeigt auch die Grenzen klimaökonomischer Modelle in ihrer Darstellung der Finanzmärkte auf. Aus diesem Grund beschäftigt sich der nachfolgende Teil dieser Dissertation mit dem Zusammenhang zwischen Klimapolitik und Finanzmärkten. In Kapitel 3 wird eine empirische Analyse der Reaktionen von Aktienmärkten auf die Ankündigung klimapolitischer Ziele durchgeführt. Die Ergebnisse zeigen, dass sich internationale Klimaverhandlungen auf die Vermögenspreise auswirken und dass Investoren zunehmend Transformationsrisiken bei CO2-intensiven Firmen erkennen. Kapitel 4 zeigt, durch eine Analyse der Aktienmärkte und des Interbankenmarktes, dass Transformationsrisiken einen großen Teil des Aktienmarktes beeinflussen können und dass finanzielle Verflechtungen negative Schocks verstärken können. Kapitel 5 zeigt, durch eine Analyse von Hypothekenkrediten, wie Informationen über Klimapolitik und die Energieeffizienz von Gebäuden in das Risikomanagement integriert und sich damit im Zinssatz widerspiegeln können. Während die Kosten von Klimaschutzmaßnahmen in großem Umfang untersucht wurden, leistet diese Arbeit zwei wesentliche Beiträge. Erstens wird die Bedeutung eines grünen Investitionsprogramms zur Stärkung des makroökonomischen Nutzens von Klimaschutzmaßnahmen hervorgehoben. Zweitens zeigt diese Arbeit unterschiedliche Ansätze, wie Transformationsrisiken und -chancen in die Finanzmarktanalyse integriert werden können. Eine frühzeitige Erkennung und Einpreisung potenzieller Risiken und Chancen kann das Finanzsystem widerstandsfähiger machen und Investitionen in die Dekarbonisierung der Wirtschaft stimulieren.

They may only be reached, or at least it would be easier to reach them, if instead of a trade-off between these objectives that implies a need for balancing them, there are synergies to be reaped. This paper discusses how the structures of economic models typically used in policy analysis influence whether win-win strategies for the environment and the economy can be conceptualised and analysed. With a focus on climate policy modelling, the paper points out how, by construction, commonly used model structures find mitigation costs rather than benefits. This paper describes mechanisms that, when added to these model structures, can bring win- win options into a model's solution horizon, and which provide a spectrum of alternative modelling approaches that allow for the identification of such options.
