These two papers, taken together, really cause a rethinking of behavioral economies.

Rather than having anomalous risk preferences; it looks like people have complexity aversion to "hard" decisions, especially on valuation, which drives behavioral anomalies. Herbert Simon ftw.

But how effective is program evaluation itself?Michelle Rao's JMP tackles this question. www.michellerao.com/research
