While carbon taxes are generally seen as a rational policy response to climate change, knowledge about their performance from an expost perspective is still limited. This paper analyzes the emissions and cost impacts of the UK CPS, a carbon tax levied on all fossil-fired power plants. To...

This paper examines how optimal renewable energy (RE) support (RES) policies need to be adjusted to account for carbon prices. We show theoretically and empirically that changing carbon prices requires adjusting RE production subsidies due to two different motives: First, RE premiums need to be...

Electricity generation based on renewable energy (RE) sources such as wind and solar replace the most expensive generators that often rely on fossil fuels. In response to RE promotion, wholesale electricity prices and carbon emissions are therefore expected to decrease. In interconnected...

This paper examines how enhanced flexibility across space, time, and a regulatory dimension affects the economic costs and CO2 emissions of integrating large shares of intermittent renewable energy from wind and solar. We develop a numerical model which resolves hourly dispatch and investment...

Technology policy is the most widespread form of climate policy and is often preferred over seemingly efficient carbon pricing. We propose a new explanation for this observation: gains that predominantly accrue to households with large capital assets and that influence majority decisions in...

Economists tend to view a uniform emissions price as the most cost-effective approach to reducing greenhouse gas emissions. This paper offers a different view, focusing on economies where society values the well-being of future generations more than private actors. Employing analytical and...

This paper examines the distributional impacts from (i) harmonizing prices for carbon dioxide emissions across sectors and EU countries and (ii) using alternative rules for carbon revenue distribution. We develop a numerical multi-country multi-sector general equilibrium model of the EU-27...

We study Germany's photovoltaic (PV) subsidy program, estimating a dynamic model of new technology adoption which accounts for heterogeneity in residential ownership structures. We find that homeowner and landlord investors heavily discount future benefits, highlighting the suboptimality of the...
