I'm busy prepping for Saturday's happiness debate in New York. I haven't been fastidiously following the happiness literature since I published my Cato paper. So if there is some interesting new work I ought to be aware of, please let me know. Also, if you are aware of anything Sachs has done touching on happiness research (all I can find is a Brookings panel he was once on), please give a shout out. I can't wait. This is going to be a blast.
