"This paper studies the dynamic behaviour of an economy under different environmental policy regimes in a New Keynesian (NK) model with nominal and real uncertainty. We find the following results: (i) an emissions cap policy is likely to dampen macroeconomic fluctuations; (ii) staggered price adjustment alters significantly the performance of the environmental policy regime put in place, especially with an emissions intensity target; (iii) welfare tends to be higher with a tax on emissions when prices are sticky; (iv) the optimal policy response to inflation is found to be very strong as long as welfare is not affected by environmental quality and the environmental policy does not consist in an emissions cap."

"We study the relationship between business cycles and the design and effects of environmental policies, particularly those with economy-wide significance like climate policies. First, we provide a brief review of the literature related to this topic, from initial explorations using real business cycle models to New Keynesian extensions, open-economy variations, and issues of monetary policy and financial regulations. Next, we provide a list of the main findings that emerge from this literature that are potentially most relevant to policymakers, including the impacts of policy on volatility and how to design policy to adjust to cycles. Finally, we propose several important remaining research questions."
