Couldn’t be more excited to launch my #DisagreeBetter initiative as NGA chair. And to those pointing out the times I’ve failed—you are correct. And I will fail again. But I promise to keep trying. There is nothing more un-American than hating our fellow Americans.

We spent $100K on a YouTube ad campaign featuring real footage of Donald Trump encouraging vaccination and... people in the targeted counties got vaccinated at higher rates than those in control counties.

[Brad Larsen @bradjlarsen]

Couldn't agree more. This was such a fun project to work on

[Steve Greene @HankGreene]

This is far away the coolest research I've ever been a part of and it was amazing to work with a totally brilliant group of scholars. @bradjlarsen, @TJRyan02, @HetheringtonUNC , @rahsaanmaxm and @steve_tadelis https://t.co/1iRLVpFYLK

@RafaelFrade11 Some confusion here thinking we created a fake video. Let me clarify that the video was not fake; it was a compilation of actual news clips from Fox News (and Fox 13 Utah) on which Trump endorsed the COVID-19 vaccines. Original Fox News story: https://t.co/GYc0ustC53

@TJRyan02 @HankGreene @HetheringtonUNC @rahsaanmax @steve_tadelis Here is the actual ad we created using Trump's Fox News interview and other clips: https://t.co/0QEsQeRGo1

[Brad Larsen @bradjlarsen]

We created a video of Trump endorsing COVID-19 vaccine (on Fox News) and showed in 1,000 counties on YouTube. Led to 100,000 additional vaccines (costing $1 per vaccine). With @TJRyan02, @HankGreene, @HetheringtonUNC, @rahsaanmax, @steve_tadelis. https://t.co/nd1MiBHJiC

A 2013 change (reversed in 2014 after efforts by @FCC) to the Digital Millennium Copyright Act temporarily banned tampering with digital locks on your phone. In forthcoming QE paper we find that buyers' values for tampered phones dropped in response to the ban

[Quantitative Economics @qe_editors]

In 2013 DMCA prohibited tampering with firmware to unlock phones from carriers-notoriously hard to enforce given consumer inattention to digital laws. Did markets react? Joachim Freyberger and @bradjlarsen find yes using new methods and iPhone auction data https://t.co/QWC3GiYGrY

A good negotiation mediator drastically increases trade, and does so by getting bargaining parties to agree sooner, not pushing disagreeing parties to keep trying. That's what we find in new NBER WP with Carol Lu and @AnthonyLeeZhang

[NBER @nberpubs]

Intermediaries have large effects on outcomes in business-to-business bargaining settings: High-performing mediators are 22% more likely to close a deal than low performers, from Bradley Larsen, Carol Hengheng Lu, and @AnthonyLeeZhang https://t.co/JRKL3XKl8D

Marketing Science just released our article, with Dom Coey, @kanesweeney, and Caio Waisman, comparing fully estimating bidder valuations to an alternative simple (and scalable) approach to directly estimating reserve prices.

NEW WORKING PAPER: @Stanford econ professor @bradjlarsen shows a scalable method for designing optimal auctions in settings with #BigData.

Love this. We found a big jump in frequency, acceptance, and *speed of acceptance* [clockwise, upper left to lower right] of equal-splitting 50% offers in ultimatum games, thousands of classroom @moblab sessions https://t.co/hfo5KkoA1g

[Brad Larsen @bradjlarsen]

This paper is joint work with @DanielKeniston, @ShengwuLi, @jjprescott2009, Bernardo Silveira, and Chuan Yu

[Brad Larsen @bradjlarsen]

Negotiators--in widely different settings/countries--favor offers that split the difference between the two most recent offers, even under incomplete information, where offers to not correspond to the actual pie. NBER Working Paper released today: https://t.co/UgaCSrr0h6

Interesting piece on proposed occupational licensing reform in Utah https://t.co/K2Moauy9cJ

[Brad Larsen @bradjlarsen]

@BarbaraBiasi We do something like this in several of the tables in our teacher occupational licensing paper (and we're citing one of your papers there😃). The code and data is in a zip folder on my website (do files 4, 8, 9 are some where we use this structure). https://t.co/QZcOjaFf76

Pricing algorithms affect the nature of competition in online markets. Using high-frequency data, we show that firms in the same market have different pricing technologies. Firms with superior technology change prices more frequently and react to price changes by slower rivals...

[Brad Larsen @bradjlarsen]

In an NBER working paper released yesterday, joint with Ziao Ju, Adam Kapor, and Chuan Yu, we demonstrate that stricter licensing requirements for public school teachers drives away teachers from less-selective colleges.

Increasing the amount of individuals who frequently or always wear a mask when within six feet of people by 1% could reduce #Covid19 deaths by 10.5%, which translates into approximately six deaths in the average US county, @voxeu evidence https://t.co/XFiPfKNmpA
