What We’re Reading

Public/Private:

WeWork seems to be facing the traditional tradeoff: Stay private, keep control, but lose access to billions of dollars of funding, or go public, raise unlimited money, and have to act normal. If it does either of those things, that will mark a sort of end of an era. At the height of the unicorn boom, big tech companies could stay private without giving up the benefits of being public, or they could go public without taking on the burdens of being public. Now they might have to make hard choices again.

Financial Turing test:

Imagine we could simulate the universe where each time you are born to different set of parents with a different genetic makeup. Sometimes you are born a man. Sometimes you are born a woman. Sometimes black. Sometimes white. Sometimes smart. Sometimes not. Etcetera etcetera. What would you do to have the highest probability of becoming financially secure regardless of your background?

Medical stats:

Every day, millions of people … swallow a small white statin pill to reduce the risk of heart attack and stroke. If you are one of those people, and go on to live a long and happy life without ever suffering a heart attack, you have no way of knowing whether your daily statin was responsible or whether you were never going to have a heart attack in the first place. Of a thousand people who take statins for five years, the drugs will help only eighteen to avoid a major heart attack or stroke. And if you do find yourself having a heart attack you’ll never know whether it was delayed by taking the statin. “All I can ever know,” Spiegelhalter writes, “is that on average it benefits a large group of people like me.”

Burning Man:

Mr. Romer, who appreciates a bit of shock value, has been showing aerial images of the city in public talks about urban growth for several years. The world, he says, needs more “Burning Man urbanization.”

By 2050, developing-world cities are projected to gain 2.3 billion people. Many of those people will move to makeshift settlements on the edge of existing cities, tripling the urbanized land area in the developing world.

“To be a little grandiose about it, this is a really unique moment in human history,” Mr. Romer told me last year. “We’re likely to decide in this time frame what people are going to live with forever.”

Drivers:

The three hallmarks of a great investment are superior returns, low risk, and long duration. The whole world concentrates on Category 1. But if you’re a leader of any merit at all, you should be treating these three as what? Co-priorities.

Have a good weekend.
