We categorize the primary incentive-based mechanisms under consideration for addressing greenhouse gas emissions from electricity generation—pricing carbon, setting intensity standards, and subsidizing clean energy—and compare their market outcomes under similar expansions of clean...

In an oligopoly market subject to environmental regulation through tradable pollution permits, polluters' output decisions affect the price of polluting. With a pollution tax, this feedback effect is absent. In a permit regime, I show that the feedback effect increases strategic firms'...

Unilateral CO2 emission reduction can lead to carbon leakage, such as relocation of power-intensive and trade-exposed industries. In the EU emission trading system, these industries are also subjected to higher cost of electricity due to emission pricing in this sector. As a result, the...
