Sergei Guriev@sguriev
We show that the expansion of 3G networks decreased government approval in countries with uncensored internet. This effect is stronger when the traditional media are censored.

We (@ArkhangelskyD, David Hirshberg, Guido Imbens, Stefan Wager and I) posted a major revision of our paper, Synthetic Difference-in-Differences, to arxiv. The paper estimates treatment effects when units are followed over time, and some receive a treatment in later periods. 1/n

Telephone operation, one of the most common jobs for young American women in the early 1900s, provided 100k's of workers a pathway into the labor force. Between 1920-1940, AT&T adopted switching technology [that then automated] more than half the U.S. telephone network...

Finally out, after years of work and great editorial guidance from Ali Hortaçsu at the @JPolEcon: journals.uchicago.edu/doi/abs/10.108…. Firms that add layers of management increase their quantity productivity but decrease their revenue productivity, since they lower their price to sell more.

1/5: Right now: @katy_milkman delivering a knockout @ChangeBcfg talk on a massive, landmark study of social science interventions to increase exercise.
Whereas only 2.5% of the interventions would be expected to increase exercise by chance, 45% actually did so.

1/ We have a new paper evaluating a very large cash transfer program for refugees in Turkey. It provides prima facie evidence that the program quickly caused substantial changes in household size and composition, with a net movement of children from ineligible to eligible HHs.

Thank you for hosting me at the @IDEA_UAB Student Seminar, @montesinos_mv and @Marta_g_rguez! It was excellent to practice presenting my #JMP and I got great feedback and questions from the seminar participants. Also, thanks @TimTkehoe for putting us in touch!
Manuel V. Montesinos @montesinos_mv
In her #JMP, @AmyHandlan studies how the information released in @federalreserve communication affects expectations and other economic variables. To do that, she relies on neural network methods to analyze the text in FOMC post-meeting statements.

Hi #EconTwitter,
As the job market begins, a central theme in the minds of both candidates and employers is the current recession. We worry that fewer jobs will lead to lower wages and fewer opportunities for market entrants.
This is also my research agenda... a thread (1/n)

This year saw many central banks arriving at swap agreements with the Federal Reserve. What determines which countries are able to access $ swap lines and (before 2002) emergency $ loans from the U.S Treasury? I explore this question in my job market paper (now updated). Thread🧵

College education in the OECD is characterized by high rates of dropout and of major switching. Is the system good at letting students learn about match-quality through experimentation, or bad at matching students to the programs they are most likely to graduate from? 1/

Interesting discussions
Beatrice Cherrier@Undercoverhist
Tonight's question, inspired by @Blinis , is what was the actual influence of the Sonnenschein-Mantel-Debreu "anything goes" theorem on the macro & micro models developed from the 1970s onward ?
(Also, why not Mas-Colell?)

Academic navel-gazing
Rachael Meager@economeager
Reflecting on seminar talks and job market talks especially, I think one key sign of a successful talk is if you're having a genuine debate about whether the ideas in the paper are wrong or not. Unsuccessful talks never communicate the ideas well enough for that debate to happen.

My last collection of response letters to a top 5 journal was 96 pages long.
Don't tell me that economists don't write books. We do, you just only get to read half of the content.

Is it OK for an econ PhD student to ask a professor whether they have projects they're looking for grad student coauthors on?
Faculty overwhelmingly think it's OK
Grad students are around 60-40
Anthony Lee Zhang @AnthonyLeeZhang
Sorry one more: Is it appropriate for a grad student to ask a faculty for coauthorship directly, and are you an econ/finance grad student, or an econ/finance faculty
