==> Martin Weitzman is one of the leading economic theorists in the case FOR aggressive government action against greenhouse gas emissions. Here he is on EconTalk.
==> An interesting graphic from John Christy’s testimony showing 102 climate models’ predictions vs. observations on global temperatures.
==> Daniel Kuehn bringing power to the people.
==> Ryan Murphy (basically) agrees with David R. Henderson and me on the ordinal/cardinal utility stuff. However, on Facebook I backed down somewhat in an argument with David Friedman, because when I was reading the climate change economics stuff (without thinking of this debate) I realized that the “pure discount rate” is clearly talking about the percentage comparison of a util today versus a util next year. Yes, there are ways you can relate this to ordinal rankings of flows of consumption over time, but economists in the trenches are clearly thinking of this as cardinal utility. (Indeed, that’s why in my dissertation I criticized Mises’ writings on the pure time preference theory–I said in certain passages Mises only makes sense if we think utility is cardinal, and surely he doesn’t want to go down that road.)
==> Tom Woods vs. Austin Petersen. It’s just what you hoped it would be. In the future I think we should build a road around Austin and then not feed him.
