I once sat through a deposition where the opposing counsel offered us fancy avocado toasts, but we weren’t allowed to touch them for ethical reasons. Things have changed.

Google Is Illegally Monopolizing Online Advertising Tech, Judge Rules The judge ruled that Google monopolized the market for two of three sets of products. It was the second time in a year that a U.S. court found it had acted illegally to remain dominant.

Court finds that Google monopolizes online advertising - very big deal. Huge congratulations to the folks at the Antitrust Division that worked so hard on this. #antitrust #Google #tech #bigtech www.nytimes.com/2025/04/17/t...

Remembering Patrick L. Bajari (1969-2025) Patrick L. Bajari was a pioneer spanning the academic and business worlds.

We are sad to announce that former faculty member and Minnesota Econ Ph.D. alum Patrick Bajari passed away on Monday.

Exclusive: Trump fires both Democratic commissioners at FTC, sources say President Donald Trump fired the two Democratic commissioners at the U.S. Federal Trade Commission on Tuesday, two sources familiar with the situation said, in another major test of the independence of regulatory agencies.

Trump fires both Democratic commissioners at the #FTC. Clearly contrary to the intent of the FTC being an independent agency. We’re well on our way to being ruled by an autocratic, authoritarian regime. This has to be stopped.

President Trump has taken an extraordinary and dangerous step of firing two FTC Commissioners.

This is a dramatic ratcheting up of the politicization of the agency--the opposite of the direction it should be going in.

These anti-science actions have made me really sad and depressed not just because my salary won't increase, but because I think of my late wife, who was a deep believer of science and who was hoping that science would save those who experience the same cancer in the near future.

Receiving breaking news about cuts to the federal workforce every day makes me extremely disturbed and disheartened. My former colleagues are dedicated public servants who sacrifice themselves to serve the nation. Without them, this country could never be great.

We are recruiting an Econometrics Adviser. The role would suit someone with a recent PhD (or a masters and some experience), and an interest in empirical IO. This is a unique opportunity to work on high-profile cases and with great data!

My RAND paper showed a temporary funding cut would have long-lasting effects on overall research output through its adverse impact on investment in young PIs.

NIH cuts billions of dollars in biomedical funding, effective immediately Researchers say it would hurt facilities that work on medical issues such as cancer research and heart disease. Elon Musk contends the old policy was β€˜a ripoff.’

Funding is crucial for research. Cuts like this wouldn’t just reduce research output in the short runβ€”they’d have long-term consequences, too. Research productivity relies on learning by doing, meaning these cuts could slow innovation for years to come.

Some of the dynamic effects has been explored by my JMP. I showed that a temporary reduction of NIH funding could lead to long lasting decline in research productivity due to learning-by-doing.

IT IS OFFICIAL! MY JOB MARKET PAPER IS IN PRINT!!!!

TL/DR: Superstar firms have used globalization to grow bigger, leveraging economies of scale. Their marginal costs have fallen, but little has passed through to customers as markups have risen.

All NIH study sections canceled indefinitely. This will halt science and devastate research budgets in universities.

There is a common notion in antitrust that greater output benefits workers.

But this paper shows that if firms have market power, this is not always the case. At high levels of markups, firms may REDUCE their (labor) input demand when they become more productive.
