We use perturbation methods to derive a rule for the optimal risk-adjusted social cost of carbon (SCC) that incorporates the effects of uncertainties associated with climate and the economy from a calibrated DSGE model. We allow for different aversions to risk and intertemporal fluctuations,...

We analyse optimal investment in one of the most important forms of climate adaptation: flood protection. Investments to build and heighten dykes and surge barriers involve considerable adjustment costs, so that their construction locks in the level of flood protection for some time. Investment...

The social cost of carbon is the expected present value of damages from emitting one ton of carbon today. We use perturbation theory to derive an approximate tractable expression for this cost adjusted for climatic and economic risk. We allow for different aversion to risk and intertemporal...
