Really proud of this paper. I think the paper has a lot to say about the observed state of the world when it comes to overall TV advertising effectiveness and profitability.
I want to be clear about what the paper doesn't say.

econometrica @ecmaEditors
New estimates of TV advertising effectiveness across 288 CPG brands show that advertising generally has little effect on sales and most brands earn a negative ROI. The results cast doubt on the sustainability of financing TV content markets with ad revenue https://t.co/jl9651Njs9 https://t.co/nxD8lbFEDT

We find that when residents of a zip code are first served by an urgent care center, total Medicare spending rises while mortality remains flat. Hospital spending increases the most. 5/

Hello, #EconTwitter! Excited to share [my first!] Working Paper Thread!🧵👇
In this paper, @talgross, @asacarny, David Silver, and I ask: how do hospitals respond to increases in payment rates?
We find: they increase admissions, reduce length of stay, and increase scale.

People are most likely to switch away from news programs during soft news stories, and least likely during sensational news.

To design social insurance, it is useful to know which households have a higher valuation of liquidity: who values an extra 💵 more?
In work in progress, we offer a creative approach to measure it. How?

Who pays for the minimum wage?
In administrative tax data from Israel, lower-income business owners and those with higher shares of minimum wage workers pay the largest shares.
Since these are not the highest-income owners, redistributive effects are limited.

Here's one way to see the key result of the paper: a binned scatterplot. The vertical axis plots hospitals' change in Medicare visits before and after the policy change; the horizontal axis plots hospitals' change in reimbursement.

Revised meta-analysis of school spending effects with
@c_mackevicius. Consistent pos relationship between spending and better outcomes in credibly causal studies. Robust to many modeling decisions, "fixes" for publication bias, and even confounding.

If you're going on the market this fall with a real estate JMP (or something else you think might be relevant to my research) — reach out and we can schedule a quick Zoom call to discuss.
Can't promise to read paper in depth, but happy to chat.

Interesting discussions

Hidden curriculum observation: audiences are eager to classify "new" ideas as essentially understood or unimportant to conserve their scarce attention. Can seem unfair/ungenerous, and in a way it is! But anyway hit them on the head with why it's new and important.

Thread about the publication process in Economics. It is inefficient. It probably made sense pre-Internet, but it is clearly antiquated by now.
It may not be the best solution, but I have a proposal. And I'm curious to hear other proposals from #EconTwitter

Currently writing a few papers with clear null effects with mechanisms, so I'm interested in how previous authors have framed nulls.
What is everyone's favorite paper where the null is the main result and is contrary to people's priors?

A bit of navel gazing ahead. I've decided to retire a paper that comprised much of my doctoral thesis from 2014. The paper simulates the search and matching process on Airbnb and shows the simulation is useful. Some thoughts on retiring the paper andreyfradkin.com/assets/simulat… 1/
