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.

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.

Funding is crucial for research. Cuts like this wouldn’t just reduce research output in the short run—they’d have long-term consequences, too. Research productivity relies on learning by doing, meaning these cuts could slow innovation for years to come. www.washingtonpost.com/health/2025/...

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. www.dropbox.com/s/33hq4dlpfz...
