In a parsimonious two-sector general equilibrium model, we challenge the widely-held tenet that within a cap-and-trade system renewable energy policies have no effect on carbon emissions. If the cap does not capture all sectors, we demonstrate that variations of a renewable energy subsidy change...

In this chapter we review research that rejects the widely held tenet that renewable energy promotion policies have no effect on carbon emissions if the electricity sector is subject to a cap-and-trade scheme. Specifically, it shows that such policies generally do have a net impact on carbon...

We present an integrated framework to understand the emissions impact of unilateral overlapping policies within a carbon-pricing system. "Internal carbon leakage" captures emissions displacement within the system (e.g., due to greater product imports from a neighbouring country). The waterbed...

Am 20. September hat die Bundesregierung die Einführung eines nationalen CO2 -Preises beschlossen. Sie hat sich dabei für eine Preisregulierung entschieden, die ab dem Jahr 2026 weitgehend durch eine Mengenregulierung ersetzt wird. Der vorliegende Artikel schlägt vor, Preis- und Mengenziel...

Beliefs about future allowance prices in cap-and-trade schemes are heterogeneous and not necessarily fully informed. This paper shows how carbon-market design affects the impact of noise traders on equilibrium prices. Price-based flexibility mechanisms encourage arbitrage by rational traders and...
