Optimal climate policy is studied. Coal, the abundant resource, contributes more CO2 per unit of energy than the exhaustible resource, oil. We characterize the optimal sequencing oil and coal and departures from the Herfindahl rule. 'Preference reversal' can take place. If coal is very dirty...

This paper presents the first empirical test of the green paradox hypothesis, according to which well-intended but imperfectly implemented policies may lead to detrimental environmental outcomes due to supply side responses. We use the introduction of the Acid Rain Program in the U.S. as a case...

Several European countries have decided to phase out coal power generation. Emissions from electricity generation are already regulated by the EU Emissions Trading System (ETS), and in some countries like Germany the phaseout of coal will be accompanied with cancellation of emissions allowances....

We investigate the displacement effects of phase-out-of-coal policies in a stylized model of electricity generation and CO2 regulation, in which a group of countries operates an emissions trading scheme (ETS). Electricity markets are either international or national and the emissions cap remains...

Germany aims to phase out coal to achieve its 2030 climate target, for which a UK-style carbon price floor is considered. But this measure comes with risks related to the uncertainty about what price level is sufficient, and the waterbed effect arising from unilateral policy under the EU-ETS....

The movement to deregulate major industries over the past 40 years has produced large efficiency gains. However, distributional effects have been more difficult to assess. In the electricity sector, deregulation has vastly increased information available to market participants through the...
