- Cyrus Samii discusses how to think about multiple hypothesis testing in pre-specifying your analysis. He links to this excellent post on multiple testing by Daniel Lakens with the great title “Why you don’t need to adjust your alpha level for all the tests you’ll do in your lifetime”.
- The Elusive Entrepreneur - From EconJournalWatch – examining the content of macro, micro, and IO classes in top PhD programs sees hardly any mention made of the entrepreneur. My work with Anna Luisa Paffhausen on how development economics is taught also found entrepreneurship to be scarcely mentioned in undergraduate and masters classes.
- Big ideas are getting harder to find – SIEPR summarizes work by Nick Bloom and co-authors: “the number of Americans engaged in R&D has jumped by more than twentyfold since 1930 while their collective productivity has dropped by a factor of 41”…It’s getting harder and harder to make new ideas, and the economy is more or less compensating for that,” Bloom said. “The only way we’ve been able to roughly maintain growth is to throw more and more scientists at it.”
- From NPR’s invisibilia podcast – is your personality fixed or can you change who you are? – discusses why the marshmallow test was designed to show the opposite of what you think it shows (h/t @m_sendhil).
- video and powerpoint of Dean Karlan’s recent SIEF talk at the World Bank on nimble RCTs.
- Planet Money podcast on Hernando de Soto (a re-run). Nice story, although they should have read Chris Woodruff’s JEL review of de Soto for some issues with it.
