Timothy Taylor, “Some Economics of Pharmacy Benefit Managers,” The Conversable Economist, September 28, 2023. This is the nicest treatment of the facts that I’ve seen. I confess that I’ve seen PBMs as something of a black box rather than doing the standard middleman treatment that Tim does.

Tim highlights the work of Matthew Fiedler, Loren Adler, and Richard G. Frank in “A Brief Look at Key Debates About Pharmacy Benefit Manufacturers,” Brookings Institution, September 7, 2023.

Ending paragraph:

As in most economic discussions about the role of middlemen, it’s important to remember that they (usually) don’t just sit around with their hands out, collecting money. Some entity needs to negotiate on behalf of health insurance companies with drug manufacturers and pharmacies. Some entity needs to process insurance claims for drug prices. I do not mean to defend the relatively high drug prices paid by American consumers compared to international markets, nor to defend the costs and requirements for developing new drugs, nor to defend some of the mechanisms used by drug companies to keep prices high. But while it might be possible to squeeze some money out of PBMs for slightly lower drug prices, and it’s certainly possible to mess up PBMs in a way that leads to higher drug prices, it doesn’t seem plausible that reform of PBMs is going to be a powerful lever for reducing drug prices.

An excerpt:

The innovation was simple in design, complex in execution, and radical in result. The business achieved a rare triple play: First, a robust new web crawler devised a superior method for finding and tagging the world’s digital content, deploying cheap PCs linked in formations to achieve momentous computing power (Brin’s genius). Second, this more prolific database of global digital content was better cataloged. A clever “Page Rank” score evaluated keyword matches, countering the influence of scammers by scrutinizing the quality of their web page links (Page’s inspiration). Third, “intention-based advertising” displayed commercial messages to searchers self-identified as ready to buy. For instance, the internet user wondering about “coho salmon, Ketchikan, kids” gave Hank’s Family Fishing B&B in Alaska a digital target for its 10 percent off coupon, while signaling to Olay not to bother advertising its skin care products. This solved the famous marketing dilemma: “I know I’m wasting half my ad budget, I just don’t know which half.” Businesses loved these tiny slices of digital real estate, and Google mined gold.

Excerpt:

In June, The Hechinger Report outlined how foreign governments are welcoming U.S.-trained international students. The United Kingdom offers a “high potential individual” visa, which authorizes a two-year stay and is available to “new graduates of 40 universities….21 of them in the United States.” Recruiters from Australia are “attending job fairs and visiting university campuses” in the United States. From 2017 to 2021, according to the Niskanen Center, a Washington-based think tank, Canada managed to attract almost 40,000 foreign-born graduates of American universities.

Most international students want to stay in the U.S. after graduating, but very few are able to do so. The U.S. does not have a dedicated postgraduate work visa. Canada and Australia, meanwhile, have streamlined the steps from graduation to employment to permanent residency. Graduates in the U.S. can complete Optional Practical Training, but it does not lead to permanent residency and lasts a maximum of three years.

Personal note: Actually the maximum of 3 years for Practical Training sounds good. When I took advantage of the F-1 Practical Training visa to be on the faculty of the University of Rochester, the max was only 18 months.

David Friedman, “Consequences of Climate Change,” September 24, 2023. David does his typical calm, clear, masterful job of laying out the facts. He takes the IPCC reports as given and then follows the implications, uncovering a lot of misleading claims in the process. While David takes as given that the earth will heat about another degree centigrade by about the end of the century, he lays out why we can’t be sure that the net effects are negative or positive. Watch about the first 35 minutes of his speech, before he gets to Q&A. I would point out highlights but there is zinger after zinger. And he references his blog and his substack where you can get details.
