Tell others you love their paper, when you do. Tell them you love how hard they are working on sthg, when that's what they are at. Tell them you struggle too, and that we connect through our common struggles as well. We never know when someone really needs to hear a kind word.
I have a joke, but I'm just too sad.
Connect with your friends, students, and colleagues in these troubling times. Take the opportunity to tell them what they mean to you. The future is bright because of what they all have to offer to the world. Make sure they know it.

On peer review, editors and journals, triggered by the JPE episode on Twitter. I wanted to give a take on what I and other editors try to do to give a fair share to papers. Peer review will always have flaws but, like democracy, is the best of the systems we have. (my view) 1/6

What message do we give as economists if missing a Nobel prize is cause for depression? This loss saddens me in more ways than one. The hope is that we live in peace with our work, and are in touch with our family and friends. RIP
“Colleagues said Professor Weitzman had grown increasingly despondent after being passed over for the Nobel Prize in economics last year and had left a note questioning whether he any longer had the mental acuity to contribute to his field.”

New NBER wp: Many diff-in-diff papers use state level laws, but what do we know about those? Two key facts. From 1950s to 90s, best predictor of law adoption is adoption by geographic neighbors. Last 20 yrs, best predictor is adoption by politically aligned states

I think this is exactly right about the culture of interrupting speakers too much in economics. It is not good and hurts especially women. Put me among those that never liked this aspect of our culture. In our seminar we have always tried hard not to do that.

Torturing your data until it speaks: Bad idea. Writing half a dozen or more articles per year: Terrible idea. Write one or two, take the time to ensure findings are robust, polish your writing, and live with the 5+ ideas that never came to fruition

Dear referees, in these hard times, editors understand if some reports need more time. Many of us have kids home or face difficulty working. But the solution is not to go back to dark days of 10 months for decisions. Reminders help keep time. Thanks truly, on behalf of authors.

W/ this team, a few years back we studied the role of gender in referees
and editor decisions. With this latest, which came out of a call by the ES society, we study gender diffs in honors in economics. For honors we observe pubs and cites, so easier to study counterfactuals
Women are under-represented in economics. Are they also under-recognized for their contributions? We study gender gaps in recognition for top honors, e.g., Econometric Society fellows, controlling for pubs and cites, going back 70+ years. Read on

This paper is important: compares publication bias across fields in same setting, MTurk studies. No pub bias for economists, huge for marketing and other social sciences (as per spike at t=1.96). No excuse for p hacking on MTurk where easy and cheap to recruit subjects for power

Interesting read. In my econ 101a i teach self control problems and altruism, and we do a risk aversion mini experiment. These topics are some of the favorites of the students, together with game theory. Slutzsky gets no love!
Economists have widely embraced the behavioral-economics revolution, but their textbooks have not. The “standard model” continues to dominate Econ 101 and introduce new generations to a neoclassical fantasyland. By

Nice paper that uses great Nielsen data and proposes a novel identification (channel #) that complements ours on Fox entry. Similar results!

Obviously we have a way to go but proud
@berkeleyecon
has had a positive role in this way
Berkeley responsible for 40% of all black Econ PhD's coming out of "top-20" programs.
That's hugely disproportionate.

I support the courage of
@ProfFionasm
who is calling it as it is: market power and oligopolies are a key cause of the rise in inequality. I hope this will be a central problem for IO to study these days.

Great paper that shows with simple but powerful design that we cannot offer elicitation mechanisms that assume rationality, when we know subjects are behavioral. This may unlock research area of studying elicitation incentives for humans, not for econs, to paraphrase

Very excited to have our paper accepted at the AER. Grateful for the reviewers’ comments, and for the constructive and very thoughtful insights provided by our editor

List of psych phenomena that do not replicate. Includes a lot of classics... In some case (e.g., Milgram) phenomenon stands, just not the original experiments. My work with
@elinos
shows up in nudges, where we do replicate effectiveness, just 5x smaller effect than pub papers
A list of all major psych research results in which we have lost confidence.
Damn.

Excellent thread on writing a job market paper. Proud that it's coming from
@TDeryugina
, one of my very first undergraduate advisees, now a star in the environmental field.
Some miscellaneous writing advice, especially for those writing up their JMP right now.
1. Completing a solid draft will take a lot longer than you think. Plan accordingly (i.e., spend as much of your research time writing as possible).

Very pleased to see this in print some 10 years since we started planning this! Are you curious about how unemployed workers search while unemployed? Do they ramp up search near expiration? Does it come down afterwards?

Laibson's Ely lecture all centered around self control, and the paradox of limited demand for commitment. This is an issue he has wondered about at least since my grad school time

Hey

I agree too. Top public schools like
@UCBerkeley
, UCLA, UMich, have been pushed to expand as demand went up. Why shouldn't Ivies expand to? It would benefit all
Strong agree. Successful institutions grow when they can train/serve more (sports, firms, religion). Selective colleges do too, but usually $ for centers, new schools. Why not more undergrads? Marginal costs are housing, food, larger intro classes— easily paid for.

We have a similar finding in paper with
@Devin_G_Pope
published in 2018 JPE. Laypeople guess on average near perfectly which of 15 behavioral treatments are most effective. Accuracy similar to one of experts. Would be good to cite related work across disciplines!
@BrianNosek
27 high-profile social science findings were evaluated by 233 people without a PhD. These laypeople predicted replication success above-chance (58%)
When laypeople were informed about the strength of evidence from the original studies, this boosted prediction accuracy (67%)
