Extremely 👀 JMP showing that policy evaluation, including RCTs, has *zero* link to further spending on the policy. The exception is when evaluations are a) done fast and b) are owned by the party in power.
The context is LatAm/Caribbean countries, but there’s lot’s here for us all to think about.

We still have a relatively poor understanding of the relationship between evidence and policy. Program evaluation in particular is often motivated by a desire to make policy better. But how effective is program evaluation itself?Michelle Rao's JMP tackles this question. www.michellerao.com/research

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.
