MEGAN MCARDLE: The Sad State of Economic Modeling.

It’s fine to say “Our best guess is that TARP and the stimulus did some good. But it’s well to remember that our best guess really isn’t very good. And putting an exact number on it–“3.1 million jobs created or saved!” creates a dangerous false precision, giving people the illusion that we have good knowledge in a very foggy area.

Indeed, it’s worth reflecting on the fact that the simulation the Fed ran–and a million others run by regulators, bankers, and investors–probably made the bubble, and the resulting crash, much worse. People thought they knew something they didn’t, and it made them complacent.

Indeed.

BESTSELLING AUTHOR SETH GODIN gives up on traditional book-publishing. I’m not sure I’m ready to go that far — Army of Davids was pretty good to me — but I can see his point: “I like the people, but I can’t abide the long wait, the filters, the big push at launch, the nudging to get people to go to a store they don’t usually visit to buy something they don’t usually buy, to get them to pay for an idea in a form that’s hard to spread … I really don’t think the process is worth the effort that it now takes to make it work. I can reach 10 or 50 times as many people electronically.”

A SUNNY LOOK AT our economic future. It’s times like this that I’m happy most forecasts are wrong.

STEM CELL UPDATE: Great news: “Researchers at the Children’s Hospital in Boston have figured out how to produce induced pluripotent human stem cells using skin cells. This is a considerable advance on earlier breakthroughs in which viruses were used to ferry the genes needed to transform adult cells into stem cells.” Ron Bailey adds: “If such IPS cells prove out, one can see the end of using stem cells derived from embryos. It is time for supporters of human embryonic stem cell research like me to acknowledge that opposition probably pushed these breakthroughs along. On the other hand, it is also time for opponents of human embryonic stem cell research to acknowledge that these breakthroughs would most likely have been impossible without earlier work on human embryonic stem cells.”

Hey, I told you so.

FISHERIES: Iain Murray says the Obama Administration’s right, and the critics are wrong. “Tradeable catch share, or ITQs, the system that is being imposed in New England, seeks to remedy this government-caused problem by introducing genuine ownership stakes in the fisheries. Wherever it has been tried, it has worked to restore collapsed fisheries by making the fishermen responsible stewards of the fish rather than, as Tierney says, hunter-gatherers. . . . Of course, because fishing fleets have been bloated by years of government interference, there will be economic casualties in the course of a move to a more responsible property rights-based system, and the process by which that works out will be seen as anything but fair by the victims.”

MICKEY KAUS: Will GM’s Big IPO Actually Happen?

GM is currently planning an IPO designed to allow taxpayers to sell at least some of their 61 percent stake in the bailed-out giant. The IPO is one of the things that lets the Obama administration claim the bailout was an “unambiguous success,” in the words of former auto mini-czar Steven Rattner.

But isn’t it looking increasingly like the IPO is in trouble? I’m not a Wall Street expert, but I can read the papers. The IPO’s already been scaled back, apparently, to the point where taxpayers may not unload enough shares to put them under the 50 percent mark. The global economy is iffy. GM has just abruptly switched CEOs . Its balance sheet is “loaded with fluff,” according to Bloomberg. Its own IPO documents admit its “internal control over financial reporting are currently not effective.” UAW locals are restive. And its market share is now seemingly below the target level. (A percentage point of share is a big deal in the auto industry.)

I smell Kabuki! Here’s the increasingly plausible scenario: The IPO was conveniently scheduled for after the November elec
