Although market power in permit markets has been examined in some detail following the seminal work of Hahn (1984), the effect of free allocation on price manipulation with market power in both output and permit market has not specifically been addressed. I show that in this case, the threshold...

In the first phase of the EU Emissions Trading Scheme (EU ETS), the price per ton of CO2 rose to over €30 before decreasing to zero by mid 2007. I examine to what extent this variation can be explained by marginal abatement costs by deriving a structural model of the allowance price under the...

We estimate the relationship between electricity, fuel and carbon prices in Germany, France, the Netherlands, the Nord Pool market and Spain, using one-year futures for base and peak load prices for the years 2009-2012, corresponding to physical settlement during the second market phase of the...

If emissions are stochastic and firms are unable to control them through abatement, the cap in a permit market may be exceeded, or not be reached. I derive a binary options pricing formula that expresses the permit price as a function of the penalty for noncompliance and the probability of an...

We study the introduction of new technologies when their costs are subject to idiosyncratic uncertainty and can only be fully learned through individual experience. We set up a dynamic model of clean experience goods that replace old polluting consumption options and show how optimal regulation...

Why do for-profit firms take voluntary steps to improve the environment? Brand appeal to green consumers or investors, the ability to influence or avoid regulation, or the experience gained for future regulation, have all been suggested as possible reasons. The empirical evidence is decidedly...

<span lang="EN-US">In this paper we develop a framework to value public investments with the purpose of increasing bicycling that explicitly accounts internal costs of bicycling, which are typically neglected in current established approaches that value bicycle spending by means of gross health benefits alone, as...</span>

We use a panel dataset of UK workers to look for evidence of compensating wage differentials for workplace risk. Risk data are available at the four-digit industry level or at the three-digit occupation level. We discuss various econometric problems associated with the hedonic wage approach,...
