What is the best way to increase demand for your service?

Get the government to make it illegal not to buy!  MarginalRevolution.com has a nice post about the "Optometry Racket:"

In every other country in which I’ve lived, ...you can simply walk into an optician’s store and ask an employee to give you an eye test, likely free of charge. If you already know your strength, you can just tell them what you want..—no doctor’s prescription necessary. ...

 The excuse for the law is that eye exams can discover other problems. ... [But] the requirement to get a medical exam from an optometrist who has spent a minimum of seven years in higher education ... creates unreasonable costs—and unjustifiable suffering….

Here is an issue that everyone but Optometrists would support:  put Americans in charge of their own vision care, and abolish mandatory eye exams!

Taxes & transfers redistribute income

IN the graph above, the share of income earned by the top 1% is plotted against time.  Based on pre-tax income, it looks as if the share has doubled.  But this does not take account of our progressive tax system and government transfer payments, like Medicaid, (bottom line).  The after-tax and after-transfer shares of the richest look pretty flat.

Incentives matter: physicians perform fewer surgeries on smokers

The move towards fixed fees, and away from fee-for-service, has given physicians an incentive to get their patients as healthy as possible before surgery, so that there are fewer complications.  Under a fixed fee system, e.g., $20,000 for a joint replacement, the surgeon makes less money if there are complications.

“A year from now, I’ll probably be at a point where I would require all my patients to stop smoking,” Spector said. “Currently, I evaluate it on a case-by-case basis. Over time, we’re going to feel comfortable being a little more stringent with our patients about these modifiable risks.” 

Edwards said he finds many patients “don’t take it well at first” when he advises them to quit smoking or lose weight. But many of them thank him later.

Sapiens, a brief history of humankind (2015)

The scope of the book Sapiens is extraordinary.  From the birth of our species, about 150,000 years ago until about 70,000 years ago, we were just another unremarkable "Great Ape."  Then about 70,000 years ago, we went through what Harari calls the "Cognitive Revolution," and we began to

...behave in far more ingenious ways than before, ... and we spread rapidly across the planet. About 11,000 years ago we enter on the agricultural revolution, converting in increasing numbers from foraging (hunting and gathering) to farming. The "scientific revolution" begins about 500 years ago. It triggers the industrial revolution, about 250 years ago, which triggers in turn the information revolution, about 50 years ago, which triggers the biotechnological revolution, which is still wet behind the ears. Harari suspects that the biotechnological revolution signals the end of sapiens: we will be replaced by bioengineered post-humans, "amortal" cyborgs, capable of living forever.  [Guardian Book review] 

Harari's grand vision is compelling, and his writing is engaging and fast moving.  So fast, in fact, that when you take time to dissect and critique what he is saying, you will find much with which to disagree.  For example, I would have had capitalism and religion playing a much bigger role in our history.  But this kind of conflict leads to growth, and after reading the book, I think I have a much better understanding of how we got here and, maybe, where we are going.

The book exhausted me, and I am reading some fiction before I go to the next two books in his trilogy.

Harari meditates for two hours every day, and goes on a 60-day silent retreat each year.  He attributes his extraordinary productivity (three books in three years) to this practice:

... It's so difficult, especially when you deal with long-term history, to get bogged down in the small details or to be distracted by a million different tiny stories and concerns. It's so difficult to keep reminding yourself what is really the most important thing that has happened in history or what is the most important thing that is happening now in the world. The discipline to have this focus I really got from the meditation.

This was enough to get me back to my paltry 15-minute prayer discipline.

Does a sense of fairness make us better bargainers?

Most ultimatum games, in which one player makes a take-it-or-leave-it offer to another, result 60-40 splits.  This occurs because the player making the offer knows that their offers will be rejected if seen as too "unfair." Some hypothesize that this notion of fairness makes us better bargainers so there might be some evolutionary basis for passing on a sense of fairness.

See how monkeys behave when they get an unfair payoff.

The benefits of being WEIRD (Western, Educated, Industrialized, Rich, Democratic)

Reputation and trust can solve a lot of business problems, like post-investment hold-up or free riding. It turns out that WEIRDo's (about 12% of the planet) have been successful, in part, because they manage to build and maintain reputations and trust more easily than others. 

 WEIRDos are more individualistic and independent, less conformist and obedient, more likely to favor “impersonal prosociality” — the idea that one set of moral rules should govern how you treat everyone, from the most distant stranger to your nearest kin. This seems normal to them, but in a global context, WEIRD people really are extremely weird. And as modernity erodes the last vestiges of traditionalism, they are probably getting WEIRDer and weirder by the day.  

 …More specifically, Western Christianity; the number of years that one’s ancestors were exposed to the medieval Catholic Church correlates pretty nicely with things like social trust, creativity and willingness to do things like donate blood — and correlates negatively with traits such as nepotism.

The world abounds in spurious correlations, of course. But the authors of “The Church, intensive kinship, and global psychological variation” propose a very plausible mechanism: the Catholic Church’s extreme obsession with incest, which isn’t found in the Eastern Orthodox branch. The church kept banning marriages between more and more distant relations, up to sixth cousins, which smashed the tight kin-based networks common to agricultural cultures.

Is predatory pricing profitable?

Predatory pricing is rare, at least in the US, because it is an investment that rarely pays off.  After an incumbent firm drives an entrant out of the market by pricing low (and deliberately losing money), the incumbent must be able to recoup the lost money by raising price--without attracting more entry--when the entrant exits the industry.

Perhaps the best examples of predatory pricing come from the airline industry, when the Department of Justice brought several cases in the 1990's.

Probably our best known airline predation investigation involved Northwest's response to Reno Air's entry into the Reno-Minneapolis city-pair in 1993. Not only did Northwest institute service of its own on this route that it had previously abandoned, it also opened a new mini-hub in Reno that overlaid much of Reno Air's own operation. Our investigation was well under way when the matter was resolved because, with the intervention of the Department of Transportation, Northwest decided to abandon its overlay of Reno Air's hub operation.

See here why these cases are so hard to win.

In other words, the government needs to prove that the low fares and extra flights would prove financially ruinous if continued indefinitely. To make the argument stick, the government will have to prove that American could reasonably expect to recover its losses after Vanguard or Sun Jet exits the market by raising fares -- confident that its high fares would not attract another round of upstarts.

What happens if we reduce drug prices by 70%?

Senator Warren's proposed policy fails a benefit-cost test:

Between 1982 and 2015, for example, the US saw the launch of 719 new drugs, the most of any country in the sample; Israel had about half as many launches. By looking at the resultant change in each country between mortality and disease, Lichtenberg calculated that the years of life lost before the age of 85 in 2013 would have been 2.16 times as high if no new drugs had been launched after 1981. For a subset of 22 countries with more full data, the number of life-years gained in 2013 from drugs launched after 1981 was 148.7 million.
