This paper evaluates the predictability of WTI light sweet crude oil futures by using the variance risk premium, i.e. the difference between model-free measures of implied and realized volatilities. Additional regressors known for their ability to explain crude oil futures prices are also...

The recent implementation of the EU Emissions Trading Scheme (EU ETS) in January 2005 created new financial risks for emitting firms. To deal with these risks, options are traded since October 2006. Because the EU ETS is a new market, the relevant underlying model for option pricing is still a...

This article documents the conditional and unconditional distributions of the realized volatility for the 2008 futures contract in the European climate exchange (ECX), which is valid under the EU emissions trading scheme (EU ETS). Realized volatility measures from naive, kernel-based and...

This paper studies the optimal hedging policy of a risk-averse firm facing both price and quantity uncertainties. In an expected utility framework, prudence in the Kimball?s (1990) sense is shown to play a major role in the characterization of the optimal hedging policy. More surprising is the...

The impact of flexibility upon hedging decision is examined for a competitive firm under demand uncertainty. We show that if the firm can adapt its production subsequently to its hedging decision, the standard minimum variance hedge ratio from Ederington (Journal of Finance 34, 1979) is...

Considering self-protection, it is a well-known result that an increase in risk aversion does not unambiguously lead to a higher level of effort. In this paper, we consider a particular case of self-protection, the choice of a lawyer, assuming a positive relation between legal expenses and...

This note studies the single-period newsvendor problem when the newsvendor faces a multiplicative neutral independent background risk in an expected utility framework. It is shown that multiplicative risk vulnerability is a sufficient condition to guarantee a decrease in the optimal order. A...

At present, it is widely recognized that under the hypothesis of perfect market, a system of emission permits is a flexible instrument to attain an environmental objective at least aggregate cost. Unfortunately, perfect market assumptions rarely hold in practice. Indeed, emission permits markets...
