If the two bonds yields exhibit identical volatility and change in lockstep—a correlation of 1—equation (17.6) reduces to equation (17.7), the traditional hedge calculation, based solely on BPV. 

This could lead to the development of a more sophisticated forward market for long-term allowances, in which low-carbon innovators could hedge against future low prices by taking a short position (i.e. agreeing to provide reductions). 

Among more recent investigations the experiments of Hammond, Medic and Hedges [69] deserve special attention. They explain the influence of the medium on orientation when nitrating 2,5-dichloro- and 2,5-dibromo-nitrobenzene. Substitution into all three free positions takes place and derivatives ortho-, meta- and...
