Climate mitigation policy should be imposed over a long period, and spur development of new technologies in order to make stabilization of green house gas concentrations economically feasible. The government may announce current and future policy packages that stimulate current R&D in...

We analyze how a country pursuing a unilateral climate policy may contribute to a reduction in global CO2 emissions in a cost-effective way. To do so its system of energy taxes and subsidies must account for leakage of emissions from the domestic to the foreign economy. We focus on leakage...

We analyse the optimal design of unilateral climate policy in an open economy where the government is committed to a target for reduction of domestic CO2 emissions but where it is also concerned about carbon leakage. We highlight the importance of distinguishing between leakage at the extensive...

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...

This paper studies the effects of capacity market reforms that the U.S. grid operators have undertaken in response to state-level subsidies paid to emission-free electricity generation. We first derive an analytical model of energy-and-capacity markets that allows us to predict the price and...

Is green consumerism beneficial to the environment and the economy? To shed light on this question, we study the political economy of environmental regulations in a model with neutral and green consumers where the latter derive some warm glow from buying a good of higher environmental quality...

This study calculates efficient taxes on gasoline and road use designed to combat driving related externalities when motorists avoid taxes due to an excessive economic driving-style. The efficient tax on gasoline is reduced below the Pigouvian rate due to such avoidance. The current US tax rate...

The general equilibrium model developed by Golosov et al. (2014), GHKT for short, is modified to allow for additional negative impacts of global warming on utility and productivity growth, mean reversion in the ratio of climate damages to production, labour-augmenting technical progress, and...

We develop a model of optimal carbon taxation and redistribution taking into account horizontal equity concerns by considering heterogeneous energy efficiencies. By deriving first- and secondbest rules for policy instruments including carbon taxes, transfers and energy subsidies, we then...

This paper analyzes the efficient emissions taxation in economies with individuals who are morally motivated to reduce their emissions footprint. They are heterogenous with respect to their morality and their consumption preferences. We distinguish between the concepts of moral and conventional...
