Facts about deaths of Roman emperors
Of the 69 rulers of the unified Roman Empire, from Augustus (d. 14 CE) to Theodosius (d. 395 CE), 62% suffered violent death. This has been known for a while, if not quantitatively at least qualitatively. What is not known, however, and has never been examined is the time-to-violent-death of Roman emperors…
Nonparametric and parametric results show that: (i) emperors faced a significantly high risk of violent death in the first year of their rule, which is reminiscent of infant mortality in reliability engineering; (ii) their risk of violent death further increased after 12 years, which is reminiscent of wear-out period in reliability engineering; (iii) their failure rate displayed a bathtub-like curve, similar to that of a host of mechanical engineering items and electronic components. Results also showed that the stochastic process underlying the violent deaths of emperors is remarkably well captured by a (mixture) Weibull distribution.

How fake news will alter foreign policy
That is the topic of my latest Bloomberg column:
Just hours after Iran’s missile strike this week on U.S.-Iraqi bases in Iraq, the Iranian government made an incredible claim: The attack, it said, had killed 80 Americans and wounded about 200, all of whom were immediately removed from the site by helicopter. U.S. officials, meanwhile, said that there were no U.S. casualties…
U.S. officials may be quite happy that Iran is claiming this “victory” without any Americans having to die. In essence, manufactured casualties may now be able to substitute for actual casualties, at least for some limited purposes.
The most likely purveyors of these fake-news casualties are the weaker sides in military conflicts. They can use fake news reports of revenge to pacify their populations. And the prouder a nation’s citizens are, the more useful such fake-news casualties will be. Fake-news casualties are also easier to fabricate in countries with censorship of the press, such as Iran.
To use the game-theoretic language of deterrence: Threats to retaliate in a painful way are now less credible because lying about retaliation is now an alternative.
Note that the U.S. does not have a comparable ability to invoke fake-news casualties….
But not all is rosy:
The possibility of fake news means that when more powerful countries wish to take action, they need to do something quite vivid and dramatic. There is no doubt — in either the U.S. or Iran — that America did in fact kill Soleimani.
All in the tradition of Thomas Schelling of course. Solve for the equilibrium!

Those new service sector jobs
Wanted: Restaurant manager. Competitive salary: $100,000.
The six-figure sum is not being offered at a haute cuisine location with culinary accolades, but at fast-food chain Taco Bell. Amid an increasingly tough U.S. labor market, the company is betting a higher salary will help it attract workers and keep them on the team.
The Yum! Brands Inc.-owned chain will test the higher salary in select restaurants in the U.S. Midwest and Northeast, and will also try a new role for employees who want leadership experience but don’t want to be in the management role.

Too much transparency makes the world more opaque.
Kathleen Kingsbury of the NYTimes editorial page is proudly announcing that instead of following their historic practice of talking with the candidates off-the-record and then announcing an endorsement they will be utterly “transparent.”
On Jan. 19, the @nytimes editorial board will publish our choice for the Democratic nomination for president. It won’t be the first time we’ve endorsed a candidate — we’ve been doing that since 1860 — but we aim to make it our most transparent endorsement process to date. Historically, endorsement interviews are off-the-record — meaning nothing said leaves the room, other than the board’s final judgement.
[But now,] in a first for @nytopinion, all presidential candidate interviews will be on the record and filmed. Next week, we’ll be publishing the full, annotated transcripts online.
What an awful idea, sure to neuter whatever influence the NYTimes might once have had.
Here’s the problem. Under the off-the-record system a candidate could sit down with some smart people and say things like “look, I know tariffs won’t help but the WTO will knock them down anyway and I need to appeal to my base.” Or, “taxes on billionaires won’t raise enough to fund everything I want but to raise taxes on the middle class we need the middle class to know that everyone is going to pay their fair share.” Or “Our troops are demoralized and the plan isn’t working.” If everything is recorded, none of this can happen.
Indeed, what possible value-added can the NYTimes make with a “transparent,” “public” process? Everything that will be said, has been said.
In contrast, a non-transparent, off-the-record process can reveal new information because less transparent can be more honest. The off-the-record system isn’t a guarantee of useful information, as the NYTimes has its biases and the off-the-record system only works because it is coarse, but coarse systems can reveal more information.
The demand for transparency seems so innocuous. Who could be against greater transparency? But transparency is inimical to privacy. And we care about privacy in part, because we can be more honest and truthful in private than in public. A credible off-the-record system leaks a bit of honesty into the public domain and thus improves information overall. Too much transparency, in contrast, makes the world more opaque.
China’s Great Transformation
Here is a new paper from Christopher Balding, and it seems to be connected to a larger book project:
How will China transform its economy from middle income to high income country in the coming decades? While economists spend large amounts of time studying debt and demographic challenges, I will take a wider approach to the structural challenges facing China needing to remake society from a middle income to income country.
I consider Chris to be one of the least-heralded very influential people. Perhaps more than anyone else, he has brought many American elites around to a more hawkish view of China.
Is U.S. average body temperature decreasing?
In the US, the normal, oral temperature of adults is, on average, lower than the canonical 37°C established in the 19th century. We postulated that body temperature has decreased over time. Using measurements from three cohorts–the Union Army Veterans of the Civil War (N = 23,710; measurement years 1860–1940), the National Health and Nutrition Examination Survey I (N = 15,301; 1971–1975), and the Stanford Translational Research Integrated Database Environment (N = 150,280; 2007–2017)–we determined that mean body temperature in men and women, after adjusting for age, height, weight and, in some models date and time of day, has decreased monotonically by 0.03°C per birth decade. A similar decline within the Union Army cohort as between cohorts, makes measurement error an unlikely explanation. This substantive and continuing shift in body temperature—a marker for metabolic rate—provides a framework for understanding changes in human health and longevity over 157 years.

The new culture of matching
Using detailed data on individual campaign contributions to Democrats and Republicans, our estimates show that firms are considerably more likely to announce a merger, complete a merger, and a have shorter time-to-completion when their political attitudes are closer. Furthermore, acquisition announcement returns and post-merger operating performance are significantly higher when the acquirer and the target have more similar political attitudes.

The Big Farmer Bailout Was Never Debated
Farmers are getting billions of dollars in bailout money to compensate for the trade war with China. If big banks or big business were being bailed out there would be an uproar but big farmer bailouts seem immune to opposition as Dan Charles points out in this piece from NPR:
…a few weeks later, the USDA announced another $16 billion in trade-related aid to farmers. It came on top of the previous year’s $12 billion package, for a grand total of $28 billion in two years. About $19 billion of that money had been paid out by the end of 2019, and the rest will be paid in 2020.
…it’s an enormous amount of money, more than the final cost of bailing out the auto industry during the financial crisis of 2008. The auto industry bailout was fiercely debated in Congress. Yet the USDA created this new program out of thin air; it decided that an old law authorizing a USDA program called the Commodity Credit Corp. already gave it the authority to spend this money.
“What’s unique about this is, [it] didn’t go through Congress,” Glauber says. Some people have raised questions about whether using the Commodity Credit Corp. for this new purpose is legal.
This is a telling example of how politics works–the process rather than the fundamental question determines much of the outcome. In this case, since the spending was not authorized by Congress there was no debate. No debate in Congress meant no opportunity for soundbites, no debate in the media and thus no debate among the public. The battle for attention was lost before it was begun. On the plus side there was no opportunity for grandstanding in Congress either and the money was approved and spent quickly.
The new culture of matching
When Jenica Andersen felt the tug for a second child at age 37, the single mom weighed her options: wait until she meets Mr. Right or choose a sperm donor and go it alone.
The first option didn’t look promising. The idea of a sperm donor wasn’t appealing, either, because she wanted her child to have an active father, just like her 4-year-old son has. After doing some research, Ms. Andersen discovered another option: subscription-based websites such as PollenTree.com and Modamily that match would-be parents who want to share custody of a child without any romantic expectations. It’s a lot like a divorce, without the wedding or the arguments.

How is Twitter disrupting academia?
Kris on Twitter asks that question. I have a few hypotheses, none confirmed by any hard data, other than my “lyin’ eyes”:
1. Twitter exists as a kind of parallel truth/falsehood mechanism, and it is encroaching on traditional academic processes, for better or worse.
2. Hypotheses blaming people or institutions for failures and misdeeds will be more popular on Twitter than in academia, but over time they are spreading in academia too, in part because of their popularity on Twitter. Blame makes for a more popular tweet.
3. Often the number of Twitter followers resembles a Power law, and thus Twitter raises the influence of very well known contributors. Twitter also raises the influence of the relatively busy, compared to say the 2009 world where blogs held more of that influence. Writing blog posts required more time than does issuing tweets.
4. I believe Twitter raises the relative influence of women. For one thing, women can coordinate with each other on Twitter more easily than they can in academic life across different universities.
5. Twitter can damage the career prospects of some of the more impulsive tweeting white males.
6. On Twitter is is easier to judge people by their (supposed) intentions than in academia, so many more people will be accused of acting and writing in bad faith.
7. On Twitter more people do in fact act in bad faith.
8. Hardly anyone looks better on Twitter, so that contributes to the polarization of many professions, especially economics and those professions linked to political issues. Top economists don’t seem so glamorous any more, not even in their areas of specialization.
9. Academic fields related to current events will rise in status and attention, and those topics will garner the Power law retweets. Right now that means political science most of all but of course this will vary over time.
10. Twitter lowers the power of institutions more broadly, as institutions typically are bad at Twitter.
