We revisit optimal investment in energy-efficiency, presenting a decision framework built around the agent's wealth and wealth dynamic. An investment rule in the form of a trigger is derived such that the agent invests the first time the energy-carrier price crosses this threshold from below....

We examine the relationship between the choice of steelmaking technology and energy prices in Germany using data beginning 1970. The analysis indicates that technology choice began to cointegrate with comparative energy prices in the early 90s. The short and long-run effects of energy prices are...

This article provides a review of economic studies analyzing the use of multiple policies - a socalled policy mix - to cope with single pollution problems. To guide and structure the review, an analytical framework is developed and applied. The framework integrates transaction costs into the...

Based on a case study on Bombay, we argue that urban infrastructure, like the sewage system and the municipal waste collection, is an important instrument for urban environmental policy. We develop a spatial general equilibrium model of a monocentric city, where infrastructure serves as a public...

Economic theory suggests that with a pollution externality and learning spillovers related to renewable energy technologies, the optimal climate policy mix includes an emissions policy and an output subsidy to the learning industry. Instead of output subsidies, feed-in tariffs are often...

Die Abschätzung der Effekte unilateraler Klimapolitik-Maßnahmen sowie deren Wirksamkeit geschieht in der bestehenden Literatur vornehmlich durch „Computable General Equilibrium“ (CGE) Modelle oder durch darauf basierende Integrated Assessment Modelle. Die Auswahl der zur Kalibrierung der...

With the expansion of renewable energy sources (RES) in countries all over the world, policy design to address the negative impacts of RES plants on their local and regional environment gains in importance. We analyse whether policy design should be spatially-differentiated or uniform when...
