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.

People love the IRS’s free tax filing website. Its future is unclear.
Elon Musk wants great government technology. It already exists with IRS Direct File.

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.

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.”

Another thing I made this year: Real and implied birds.
A six-panel cartoon titled "real and implied birds". In the two panels in the top row, there's a rough legged-hawk sailing through the sky, next to a smooth legged hawk, which has smooth human legs. In the second row, there's a great-crested flycatcher looking dapper, next to an ok-crested flycatcher that has just a slightly less nice crest. In the third row, there's a mountain chickadee standing up on stones, next to a valley chickadee peeking out from a dip between stones. In the fourth row, there's a least bittern standing in some reeds, next to a most bittern that is enormous and stomping through a city, with people running in fear, helicopters overhead, and an overturned car on fire.

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.
110
Ben Lockwood @benlockwood.com · 28/11/2024
Could be, but my understanding of the JC Penney experience was that Johnson replaced time-varying prices and coupons with stable prices, and they lost market share overall. If people hate complexity, that might predict market share would have increased?

This seems plausible, but it’s interesting that in some settings people seem to like the way price fluctuations give them a chance to find a good deal.

Love this agenda. @ivanwerning.bsky.social: re discounting, Ryan has another paper suggesting hyperbolic discounting arises even without temporal delays. Here too, I’m interested in what hinges on whether it “looks” blue or is “actually” blue.

There's an oversold flight from Madison to NYC, and they're offering a free Lyft to Milwaukee (~1hr drive), a direct flight to NYC, and an Amazon gift card. The gift card is up to $1500, but no one is budging. It feels like a mini anti-corporate rebellion, and I'm curious to see how far it goes.

This fantastic map shows travel time from London to the rest of the world in 1881
This is an isochronic passage chart for travelers created by Francis Galton. The Princeton library catalog has this description "Landmasses and oceans colored according to travel time (in days) to those points from London, ca. 1881. Includes explanation of colors, showing days journey indicated by each color. Includes note: "showing the shortest number of days journey from London by the quickest through routes and using such further conveyances as are available without unreasonable cost. It is supposed that local preparations have been made and that other circumstances are favourable." From: Proceedings of the Royal Geographical Society and monthly record of geography."
