This paper examines the effects of firm-level innovation in carbon-abatement technologies on optimal cap-and-trade schemes with and without price controls. We characterize optimal cap-and-trade regulation with a price cap and price floor, and compare it to the individual cases of pure taxation...

Naturwissenschaftliche Fragen rund um den Klimawandel sind von Naturwissenschaftlern zu beantworten. Ökonomen und Wirtschaftsethiker können jedoch dazu beitragen, den Klimawandel und mögliche Gegenmaßnahmen zu bewerten. Dabei ist ein einheitlicher Preis für die Emission von Treibhausgasen...

We explore the history and current status of green energy finance in Australia and New Zealand. Although both countries have enviable renewable energy resources with a 100% renewable mix considered feasible, the two countries present highly contrasting contexts for energy finance. Currently, and...

International shipping is an important emitter of greenhouse gases. The International Maritime Organization (IMO) is discussing different approaches to reduce maritime CO2 emissions, in particular market-based mechanisms. In this paper, we assess potential implications of a maritime emission...

We develop a three-stage model of abatement technology search, adoption, and deployment. Using this model, which draws on search theory tools more frequently used in labour and monetary economics, we compare market-based and command-and-control pollution control instruments with respect to the...

Deep decarbonisation requires large-scale irreversible investments throughout the next decade. Policymakers discuss Carbon Contracts for Differences (CCfDs) to incentivise such investments in the industry sector. CCfDs are contracts between a regulator and a firm that pay out the difference...

Nitrogen management policies introduced in the past decades by some OECD countries have succeeded in reducing excess nitrogen use by farmers, but half of global mineral fertiliser use is still lost for crops. While about half of OECD countries have nutrient surpluses of between 25-50 kg N per...

Cap and trade mechanisms enjoy increasing importance in environmental legislations worldwide. One of the important aspects of designing cap and trade mechanisms is the possibility of authorities to grant emission permits for free. Unlike analyzed in the seminal contributions on cap and trade...

Green innovation is essential for climate change mitigation, but not all innovative projects deliver equal social value. We consider innovator heterogeneity in a model where the policy maker cannot observe innovation quality and directly subsidize the socially most valuable green innovations. We...
