What are IAMs?

Classification(Weyant,2017):• Benefit-cost
IAMs
• DetailedprocessIAMs
Literature overview
• Benefit-costIAMs:• MostlyDICE-like(Goeset.al,GramstadandTjotta,Moreno
CruzandKeith,Belaiaet.al,Helwegenet.al)• Highlysensitivetoparametrizationofcostsandbenefits• DegenerateapplicationofCBA
• DetailedprocessIAMs• Veryfewcontributions(Arinoet.alPNAS2016,Emmerlingand
Tavoni,GEC&ERE)• Oftenaccompaniedbyanalytical/theoreticalmodeling• OftenhybridwithCBA

Open issues which need to be resolved (and won’t be easy)Data:• Climatechangeeconomicimpacts
• Recentempiricalliterature(Burke,Hsianget.al):higheconomicimpactsandinequality->largescopeforSRM(Hardenal2019)
• Butalsohighuncertainty,especiallyatthecountrylevel(Ricke,Caldeira,DrouetandTavoni)
• BasedonTemp:precipitation,CO2• SRMeconomicimpacts
• Empiricalliterature(Proctorforvolcanoes,fires?)• Airquality• Governance(includinglabexperiments,forthcoming)
Frameworks:• Exploratoryanalysiswillgrow,morecomplexmethods(multi-objective,deep
