The paper derives the optimal carbon tax in closed-form from an integrated assessment of climate change. The formula shows how carbon, temperature, and economic dynamics quantify the optimal mitigation effort. The model’s descriptive power is comparable to numeric models used in policy...

Ein vom ifo Institut entwickeltes Konzept zur CO2-Bepreisung mit dem Titel »Flexcap« verbindet die Vorteile von CO₂-Steuer und Emissionshandelssystem und stellt eine effizientere Lösung als die Reinform beider Instrumente dar. Ein reines Emissionshandelssystem wälzt alle Unsicherheit in...

The present work is dedicated to theoretical aspects of long-term evaluation with a focus on time and uncertainty structure. Motivated along the lines of global warming, the analysis renders contributions to the fields of environmental economics, decision theory, the economics of sustainability...

Die Arbeit beschäftigt sich mit einer axiomatischen Charakterisierung von Wahlfreiheit. Im ersten Teil analysiere ich im statischen Kontext bestehende Axiomensysteme und erarbeite ihre impliziten normativen Annahmen und Defizite. Aus ihnen leite ich die Notwendigkeit ab, sowohl die...

We study clean energy subsidies in a quantitative climate-economy model. Clean en-ergy subsidies decrease carbon emissions if and only if they lower the marginal product of dirty energy. The constrained-efficient subsidy equals the marginal external cost of dirty energy multiplied by the...

The prevailing literature discusses intergenerational trade-offs predominantly in infinitely-lived agent models despite the finite lifetime of individuals. We discuss these trade-offs in a continuous time OLG framework and relate the results to the infinitely-lived agent setting. We identify...
