Paper summaries
Fascinating finding: long-term (~600 years!) intergenerational earnings elasticity is about 0.04. Italy is probably the only country in Europe that allows for this kind of exercise due to a large number of unique last names and their (relatively stable) geographic distribution.
The Review of Economic Studies @RevEconStud
Here's the money graph.
In it we plot prescription fills around payday for people about to receive their checks relative to fills for people who won't receive their checks for 2 weeks.
Red = ppl paying $2-5 copays per script
Blue = ppl whose copays are fully subsidized
A big part of the remaining gender gap in earnings can be accounted for by the differential impacts of parenthood on the careers of women and men.

At a top business school, women receive lower grades in quantitative courses compared to men who have similar academic aptitudes, GPAs, family backgrounds, and demographics as captured by their college applications.
This gap closes if the instructor is female.
New paper 🧵
Using a diff-in-diff, I find firms responded to AMTBIA87 by engaging in earnings management and tax sheltering behavior to reduce their book incomes. My estimates correspond to an elasticity of book income wrt the net of tax rate of 3.8 over 3yrs, and 3.2 over 6yrs.
So @nirupama_rao and I are finally in print. We look at why alcohol taxes are often "overshifted" so that $1 of tax leads to >$1 of price increase. Originally we thought PTR > 1 was an artifact of limited data from some weird tax increases in the 90's (Alaska?) ... 1/9
AEA Journals @AEAjournals
👇Very interesting research by @noriko_amanopat (@CamEcon).
Estimates that a 45%⏫in the budget of the lowest quintile of the US income dist. would make them divert part of their expenditure from unhealthy to healthy products, closing the gap w.r.t. higher income hhds. by ~40%

Happy to share that our new paper 'Measuring Price Selection in Microdata - It's Not There' with Raphael Schoenle and @JesseWursten is out as a @cepr_org discussion paper. What did we learn about the flexibility of the price level? A tread. cepr.org/active/publica…

An unexpected benefit of paid maternity leave: more women go to college. When women expect to be able to benefit more from work, they invest more in their own education. This analysis shows paid leave in California increased female college enrollment by 2% papers.nataliaordazreynoso.com/NOR_JMP_OCT.pdf

Good discussions
Tweetorial on going from regression to estimating causal effects with machine learning.
I get a lot of questions from students regarding how to think about this *conceptually*, so this is a beginner-friendly #causaltwitter high-level overview with additional references.
How do you think policy-makers and others weigh impact evaluation results?
Aidan Coville and I asked researchers to forecast findings from a discrete choice experiment through the Social Science Prediction Platform. A thread. 👇 1/
I think this will be a trend.
Right now a lot of organizations hire communications pros to try to get journalists to cover what they do.
In the future, more will hire people to directly produce the journalism.

Some academic job market advice.
When prepping materials (cover letter, research, teaching, diversity statements...) here is my personal view:
1. We will look at these for 20 seconds before deciding if we read for another 45 seconds. This means:
Make it easy to skim!
