Our new analytical general equilibrium model is used to study effects of tightening state Renewable Portfolio Standards (RPS) on electricity price, CO2 emissions, fossil fuel electricity generation, and two kinds of renewable generation. We show how those outcomes depend on key state...

To decarbonize the power sector policy-makers need to commit to long-term credible rules for climate and energy policy. Otherwise, time-inconsistent policy-making will impair investments into low-carbon technologies. However, the future benefits and costs of decarbonization are subject to...

In June 2018, an agreement between key EU institutions - the Commission, the European Parliament, and the European Council - was reached after a long-lasting discourse over the 2030 EU climate and energy policy package. This paper offers a comprehensive assessment of the EU package, with its...

We examine how Green governments influence macroeconomic, education, and environmental outcomes. Our empirical strategy exploits that the Fukushima nuclear disaster in Japan gave rise to an unanticipated change in government in the German state Baden-Wuerttemberg in 2011. The incumbent rightwing...

Myriad policy measures aim to reduce greenhouse gas emissions from the electricity sector, promote generation from renewable sources, and encourage energy conservation. To what extent do innovation and energy efficiency (EE) market failures justify additional interventions when a carbon price is...

We formulate a model with black, green and white certificates markets that function in conjunction with an electricity market. The markets function well in the sense that a common equilibrium solution exist, where all targets are satisfied (e.g. share of green electricity and share of energy...

In a field experiment tracking 390 electric vehicles minute-by-minute, we show that incentives reduce charging by 17%—27% during peak times and increase it by 34% during midday when solar generation is highest. Peak charging decreases at home, while midday charging rises out of the home....

This policy note investigates whether the current level of public support to environment-friendly technologies is sufficient to allow European countries to respond to the multiple challenges posed by climate change and other environmental concerns. We first lay out the justifications for...

We investigate how irreversibility in "dirty" and "clean" capital stocks affects optimal climate policy, from both theoretical and numerical perspectives. An increasing carbon tax will reduce investments in assets that pollute, and so reduce emissions in the short term: our "irreversibility...

We build a general equilibrium model to study how climate transition risks affect energy prices and the valuations of different firms in the energy sector. We consider two types of fossil fuel firms: incumbents that have developed oil reserves they can extract today or tomorrow, and new entrants...
