Guys, come on, the Q effects of a tariffs are negative. Also, in the spirit of the CEA, you can assume a trade elasticity of 4 and then divide that by 4 for no reason, so assume a pass-through rate of 100%. So 50.5 Dalmatians.

That really does ruin it. Especially the 0.5.

What do you think of this exercise as a commentary on whether the methods are trustworthy, rather than on the truth of the implied conclusion? (This reminds me a bit of the height tax paper and its authors’ differing interpretations of it.)

Watching March Madness, it sure feels like this would be a good venue for an ad campaign from universities about how America’s higher ed system is one of its greatest strengths.

You shouldn’t finish every book you start.

Abandoning a book is not an admission of failure—it’s a sign of wisdom. You’ve decided to let go of sunk costs.

The purpose of reading is to be entertained and informed. If a book doesn't bring joy or insight, it’s time to move on.

Direct File’s future is in doubt as this administration evaluates whether the renew it. I hope they do. Taxpayers say it makes filing easier and more efficient. If the administration allows the program to scale up, it will get credit for that improvement. (Not to mention the boost to GDP.)

Some say that the free filing options from private sources, like TurboTax, are enough. But this is one area where government is well placed to be more efficient—it has the information necessary to pre-fill tax returns. There’s a reason other countries do this in-house.

Direct File has been a big step toward making tax filing easier and more efficient. It has started small, with 12 states in 2024, and has expanded in scale (up to 25 states this year) and scope (supporting more tax situations, with plans to have more pre-filled information).

In contrast, the average American spends an estimated $210 and 11 hours to file their 1040 personal income tax return. Those are real costs—that time could be spent producing real goods and contributing to GDP. www.irs.gov/pub/irs-prio...

Americans are often jealous (or incredulous) to find out that in many other countries it is trivially easy to file taxes—you receive a form pre-filled with info the government already knows about your tax situation. Denmark adopted this in the 1980s, and by 2020 most OECD countries had as well.
What are prepopulated tax returns?

A bright spot in recent tax policy has been the success of the IRS's in-house Direct File program, which allows many taxpayers to file taxes for free online through a simple interface, even on their phones. Let me tell you why I think so, and why Direct File’s future is at a crossroads. #EconSky

Congestion pricing targets even more externalities than I realized.

From the Jan. 5 start of congestion pricing to March 6, complaints about honking were down 69% relative to last year (via NYC's 311 portal).

Great piece on the mechanics of achieving PA’s recent success in promoting reform.

“The visibility of the initiative also encouraged a sense of competition among cabinet officials. The mantra of “moving at the speed of business” was widely adopted among those working with the governor.”
New, from me: I’ve been writing about the damage done at the federal level, but am also looking for positive examples.

Permitting reform in PA is one such case.

Rapid and positive change is possible by improving state capacity rather than destroying it.

I like the urgency and thrill story. Not sure I believe discounts are simpler than stable prices. I can also believe this is highly heterogeneous—Johnson’s strategy came from his success at Apple retail, which has stable prices, but it fared terribly at JCP.
