Non-dogmatic climate policy

Disagreements about normative aspects of social time preferences have led to estimates the cost carbon (SCC) that differ by orders magnitude. We investigate how disagreements SCC change if planners are nondogmatic, is, they admit possibility a in their views and internalize future selves. Although nondogmatic may disagree all contentious preferences, reduce dramatically. Admitting once every 40 years results fivefold reduction range recommended SCCs.
