The Regional Greenhouse Gas Initiative (RGGI) was passed by an original collection of 10 northeastern states and is the first cap-and-trade policy in the United States to specifically target carbon dioxide emissions from the electricity sector. We exploit the introduction of this policy and...

To gain institutional and technical know-how for a national carbon market, since 2013 China has experimented with eight regional carbon emission trading system (ETS) pilot programs. The prominence of these policy experiments and their unusual tradable performance standards (TPS) design have...

The paper at hand examines the power system costs when a coal tax or a fixed bonus for renewables is combined with CO2 emissions trading. It explicitly accounts for the interaction between the power and the gas market and identifies three cost effects: First, a tax and a subsidy both cause...

Energy system and power market models refrain from distinguishing between private and social discount rates. We devise a strategy to account for diverging private and social discount rates in intertemporal optimization frameworks, resulting in an optimal carbon tax above the marginal damage when...

Current decarbonization policies neglect damages from local air pollutants. We analyze the trade-off between complementary taxation of carbon emissions and local air pollution. We quantify results for the European power market until 2050. Taxing only air pollution results in social cost of 5,890...

This paper explores how a principal with time-inconsistent preferences invests optimally in technology or capital. If the current principal prefers her future self to save more, she can increase current investments complementary to future savings and decrease investments in the strategic...
