I investigate the impact of the European Union Emissions Trading Scheme (EU ETS) on fuel efficiency of fossil fuel power plants using administrative micro data on power plants in Germany from 2003 to 2012. I find positive efficiency effects in fuel use, leading to a decrease in fuel input of 0.4...

Consider a dynamic model with two countries or coalitions that consume and trade fossil fuel. A non-abating country owns the entire fuel stock and is not concerned about climate change, represented by a ceiling on the carbon dioxide concentration. The government of the other country implements...

In a two-period model with two groups of countries that extract, trade and consume fossil fuel, a climate coalition fights against climate damage by purchasing or leasing deposits to prevent their extraction, and seeks to manipulate the fuel prices in its favor. The deposit-purchase policy is...

Fossil fuel subsidies undercut the international community's Sustainable Development Goals and climate change objectives in many ways. Estimated at several hundred billion dollars a year, such subsidies also affect fossil fuel prices, and can therefore have distorting impacts on trade and...

The purpose of the paper is to (i) show that univariate GARCH is not a special case of multivariate GARCH, specifically the Full BEKK model, except under parametric restrictions on the off-diagonal elements of the random coefficient autoregressive coefficient matrix, that are not consistent with...
