- 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.”
multiple hypothesis testing
The demand for pre-analysis plans that are registered at a public site prior available for all consumers to be able to examine has recently increased in social sciences, leading to the establishment of several social science registries. David recently included a link to Ben Olken’s JEP paper on pre-analysis plans in Economics. I recently came across a paper by Humphreys, de la Sierra, and van der Windt (HSW hereon) that proposes a comprehensive nonbinding registration of research. The authors end up agreeing on a number of issues with Ben, but still end up favoring a very detailed pre-analysis plan. As they also report on a mock reporting exercise and I am also in the midst of writing a paper that utilized a pre-analysis plan struggling with some of the difficulties identified in this paper, I thought I’d link to it a quickly summarize it before ending the post with a few of my own thoughts.
