I use an applied general equilibrium model to quantify the influence of a new, theoretical channel for carbon leakage effects, as identified by Fullerton, Karney and Baylis (2012). I first produce parameterizations of the model that generate a close correspondence with the theory, isolating the quantitative effect of this channel. I then produce parameterizations that allow for an examination of net leakage rates in a model with a more comprehensive set of leakage channels. I find that the new channel exerts a negative influence on net leakage rates but that positive forces of leakage dominate in the comprehensive assessment.
