    A limited preview of my book with Dan O'Flaherty (out next month) is now available; the preface should give a sense of what the book is about:

    Alan Krueger taught me a lot about pain. That people are in a lot of pain when they are unemployed, and searching for a job was their most painful part of the day. That men w/out work reported a lot of pain & took a lot of pain relievers. [1/3]

    We are all in shock. I can't imagine Princeton without Alan. I owe him so much, as my mentor, co-author, and colleague. I wish I had another chance to say thank you.

    Introductory economics education should include a much bigger hands-on empirical component. I like what is doing. They could be the next "consensus" textbook for introductory econ.

    Very nice, simple illustration here of Simpson's Paradox

    On the occasion of Edward Simpson's passing, Simpson's paradox. It's possible for a baseball player to have a better batting average in two separate years, but worse when they are combined. Implications for not just baseball but epidemiology:

    I’m disappointed to see someone as smart as Renato to use the Manafort sentence as an opportunity to raise the old bugaboo of “sentencing disparities” caused by judicial sentencing discretion. It’s misleading, if not disingenuous. 1/

    Manafort’s flawed and inadequate sentence is the result of a system that gives federal judges extraordinary latitude and does not sufficiently review and overturn bad sentences. We need greater review of sentencing decisions. My piece in :

    For context on Manafort’s 47 months in prison, my client yesterday was offered 36-72 months in prison for stealing $100 worth of quarters from a residential laundry room.

    Beatrice, brilliant as usual, with a beautiful thread on the mathematical turn in 20th c econ -- connections with debates in math, older ideas about physics-econ connections... Quotations still have a vividness & urgency today. Her X students lucky to get this course.

    This thread is worth reading:

    This awed tone of MSM coverage of is so gendered. Harris and Klobuchar are both daughters of single mothers who had to raise their kids alone after their husbands left the families. Warren also grew up in a working class family in Oklahoma. THREAD📌📌📌 1/

    This thread is a perfect example of how to explain a counterintuitive idea with clarity and without jargon, and provide empirical evidence in support of it, all without claiming more than the evidence will support

    1/ If you are feeling bored, let's talk about the very low interest rate and why it may not be good for the global economy. I am talking about long-term rate (r), e.g. 10 year treasury, which is not directly determined by the central bank.

    Yes people LOVE refunds. Average has been about $2700. That is a *choice*. The decision to reduce withholding to provide immediate but unnoticeable increases in take home pay was behaviorally uninformed. $10/week not noticed. $500 lower refund is.

    Feels like there's a good behavioral finance lesson in the degree to which people like to get tax refunds, even if technically it means they were floating a no interest loan to the government.

    Stellar group, and interesting entry barrier: "Membership in the EfIP network is open to all academic economists. Members are appointed after nomination by an existing member and following the submission of a 10-page policy brief."
