New paper at the JPE: students make really important long-term decisions without very much information about the earnings of different careers, which we should probably give them (even if students also value non-pecuniary aspects of careers)

New WP! Where Does Wealth Come From?
Important ? to consider when thinking about inequality.
(w/Devereux, @FannyLandaud, and Salvanes)

Very interesting new evidence that sector-focused training programs generate large & persistent earnings gains (11 to 40%!) by getting workers into higher-wage sectors, from @lkatz42 @jondr44, Richard Hendra, & Kelsey Schaberg @nberpubs.
Lawrence Katz @lkatz42
Sectoral employment programs generate large earnings gains in multiple RCTs through training in transferable and certifiable skills and reductions of employment barriers to high-wage sectors -- see our new @nberpubs working paper https://t.co/jQVcolS06p

Interesting discussions

Frustrating, common referee response: "the results are obvious from the assumptions."
Okay? Had you thought of laying out these assumptions? Have you seen someone else?
I guess I need to make my model more confusing?
