27We compare a carbon tax and a cap and trade mechanism in their propensity to induce carbon-reducing technological adoption, when investments are undertaken under uncertainty. In our setting, risk-neutral firms affect the variance and the
correlation of the shocks they are exposed to through their technological choice,
making uncertainty endogenous. We find that uncertainty associated with a given
technology always impacts expected profits under a carbon tax, while under a cap and
trade this is the case only as long as the shocks are not correlated across the firms; if,instead, shocks are perfectly correlated, uncertainty has no impact on profits. As a result, we show that, while under a carbon tax, initially symmetric firms tend to have symmetric strategies in equilibrium (either of adoption, or non adoption), a cap and trade system might also induce asymmetric adoption. Finally, we discuss several policy applications of our work, including an analysis of the effects of combining feed-in tariffs
with carbon tax or cap and trade.
