International carbon markets are frequently propagated as an efficient instrument for reducing CO2 emissions. We argue that such markets, despite their desirable efficiency properties, might not be in the best interest of governments who are guided by strategic considerations in negotiations. We...

According to the Phase IV (2021-2030) rules of the EU ETS, the total amount of emissions permits allocated to firms is not fixed but endogenous. This implies that a national climate policy that overlaps with the emission trading system can have an impact on total aggregate emissions. Roughly...

Currently, the European Commission intends to increase the EU’s 2030 climate target. Instead of a 40 percent target, greenhouse gas emissions would be reduced by 50 to 55 percent compared to 1990 levels; the European Parliament is even considering a 65-percent reduction. The European Emissions...

I examine a policy-making game among countries that must choose both a policy instrument (e.g., a tax or a quota) and its intensity (i.e., the tax rate or the quota level) to price pollution. When countries price pollution non-cooperatively, they not only set the intensity inefficiently, they...

Every government that controls an exhaustible resource must decide whether to exploit it or to conserve and thereby let the subsequent government decide whether to exploit or conserve. This paper develops a theory of this situation and shows when a small probability that some future government...

This paper discusses lessons that other regions could learn from European Union’s effort to implement carbon pricing through EU Emission Trading System (EU ETS). Our lessons are, first of all, that a cap-and-trade system like EU ETS is very helpful in guaranteeing a credible and binding...

In addition to carbon dioxide, air traffic operation affects the climate through other emissions and atmospheric processes, such as the formation of ozone and contrail cirrus. The climate impact of these non-CO2 effects is strongly dependent on the emission location (in particular cruise...
