Hi #EconTwitter! I'm a job market candidate @Caltech in IO and Finance. My research focuses on innovation, entrepreneurship, & antitrust regulations.

My #EconJMP introduces a novel empirical framework to evaluate the impact of mergers on labor markets.

Super interesting paper by @jbbecon on the policy impact of two of my antitrust idols (@timobres and Steven Salop)

*Very* happy to see this 'in print'. Along with our paper "Labor Market Power", and "Merger Guidelines for the Labor Market", we present an set of tools / data / applications to big policy questions in labor markets. Its not perfect, but its a start!

[Chris Conlon @conlon_chris]

I think this is an important insight for the labor market literature, one IO economists have been (w/o success) pushing for some time.

The key insight from IO is that that concentration is an outcome rather than an input.

Some thoughts below... 1/

Together with @JVanBiesebroeck we just finished the paper "Demand, Competition and Public Policy in the Automobile Industry - An Overview of Research since BLP"

Happy reading, while waiting to see whether Empirical IO will get a Nobel prize this year

Flip 100 coins, labeled 1 through 100. Alice checks the coins in order (1, 2, 3, …) while Bob checks the odd-labeled coins, then the even-labeled ones (so 1, 3, 5, …, 99, 2, 4, 6, …). Who is more likely to see two heads *first*?

[Herbert hovenkamp @Sherman1890]

Very interesting antitrust complaint filed Sep 12 against major scholarly journals for agreement 1) to require single submissions; 2) not to compensate reviewers, etc. https://t.co/bp5ehXAnfG

Spectrum auctions proving that economic theory has had impact on the real world.

🚨 May Day Paper🚨

The FTC has gone all in on labor markets in the past 5 months:

1. Merger guidelines
2. Kroger/Albertsons
3. Noncompetes

How straightforward will it be to apply antitrust to labor?

@AuerDirk, @geoffmanne, and my paper lay out some challenges ahead 🧵

Congrats to my officemate!!

Excited to announce that I’m joining @BUQuestrom this summer as an Assistant Professor of Marketing! This is a dream come true to pursue my research interests.

I’m really grateful to my advisors and others at @Caltech who helped me get this far! #EconTwitter

On 9 March, some things might change:

1. you can message from Whatsapp to Telegram

2. in the App Store you can buy directly from the provider or competing platform

3. Amazon no longer ranks own products at the top of a search

Why? The Digital Markets Act (DMA) goes live…

[Kevin A. Bryan @Afinetheorem]

I am working on a solution to this for innovation & entrepreneurship, but in the meanwhile, for folks who don't know, no one gives a damn in our field if you put your papers on your site, arXiv or SSRN. Google Scholar will find them! Do you part for the dissemination of science.
