In this article we specify a model of millet prices in the three West African countries of Burkina Faso, Mali, and Niger. Using data obtained from USAID’s Famine Early Warning Systems Network (FEWS NET) we present a unique regional millet price forecasting model that takes advantage of the...

Are private voluntary environmental actions by firms a sign of mismanagement, or a profitable “win-win” replacement for regulation? Empirical evidence is decidedly mixed. In this study, we use 19 years of monthly stock price returns, from 1991 to 2009, to examine the profitability of...

We use a panel dataset of UK workers, combined with risk data at the four-digit industry level, to look for evidence of compensating wage differentials for workplace risk. We discuss various econometric problems associated with the hedonic wage approach, namely the instability of the estimates...

In the first phase of the EU Emissions Trading Scheme (EU ETS), the price per ton of CO2 initially rose to over [euro]30; the price then collapsed to essentially zero by mid 2007. By deriving a structural model of the allowance price under the assumption of efficient markets I examine the extent...

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...
