Musical mortality

Check out this fascinating actuarial analysis of the life expectancy of popular musicians (broken down by musical genre) prepared by Dianna Theadora Kenny, a professor of music and psychology at the University of Sydney. According to Prof. Kenny, accidents are one of the main causes of death among musicians, especially for men: “For male musicians across all genres, accidental death (including all vehicular incidents and accidental overdose) accounted for almost 20% of all deaths. But accidental death for rock musicians was higher than this (24.4%) and for metal musicians higher still (36.2%).” The table below provides an even more comprehensive statistical picture:

“Choking and Excelling at the Free Throw Line”

That is the title of this excellent empirical study by Darrell Worthy, Arthur Markman, and Todd Maddox. In case you’re wondering, their data set was comprehensive: it consisted of all free throws attempted during the last minute of all regular-season and playoff games in the three seasons of 2002-03, 2003-04, and 2004-05. The authors conclude that players tend to shoot worse than their career average when their team was behind or ahead by one point. (By the way, their elegant paper is only six pages long–five, if you exclude their bibliography! But if you’re pressed for time, fellow blogger Phil Birnbaum wrote up this helpful overview of the paper as well.) On a more personal note, although the paper was published way back in 2009, we stumbled upon it for the first time late last night while we were playing on the Internet during a bad bout of insomnia. Sometimes it pays to stay up late!)

Starfleet mafia?

Although we haven’t seen the new Star Trek movie yet (Star Trek Beyond), in today’s post we want to pose the following question about the fictional world of Star Trek: who pays for Starfleet? According to Wikipedia, “Starfleet is a service maintained by the United Federation of Planets [in the fictional universe of Star Trek] as the principal means for conducting deep-space exploration, research, defense, peacekeeping, and diplomacy.” But this definition begs the “who pays?” question. Who pays for this expensive “service”? Our friend and colleague Ilya Somin, a law professor at George Mason University, offers this intriguing conjecture: the men and women of Starfleet are interplanetary tax collectors. To put it less politely: Starfleet operates an interplanetary protection racket! In the words of Professor Somin: “The human-dominated Star Fleet military is the only visible Federation military force, and is perhaps tasked with collecting tribute from the nonhuman planets for redistribution to Earth. But as long as they pay their taxes, which subsidize Earth’s welfare state and Star Fleet itself, they are largely left alone to govern their domestic affairs as they see fit. The Federation is essentially a big protection racket. Like the Mafia, it provides ‘protection’ in both senses of the word: external security, and also ‘protection’ against its own depredations.” (If you want to do further research on this question, you can find links to additional conjectures here.)

Strategic dating

Roy Lugasi and Hod Gerlitz co-founded a new dating app called Weepo that allows users to monitor the male-to-female ratio at a bar or nightclub. According to this fascinating report by James Covert, writing for the New York Post, “The big idea … is mainly to cut short the prolonged chats that have long plagued other dating apps—ending, too often, with no date at all. ‘With all those other apps, you have to go through a conversation where it takes two or three days to meet up,’ [Roy] Lugasi told The Post. ‘With this app, you’re practically guaranteed to meet somebody tonight.'” In other words, finding someone to date is a time-consuming task. Most dating sites don’t really reduce the search costs of dating by much because finding a match on a computer or smart phone does not substitute for going out on a date. Thus, from an economic perspective, the main purpose of a dating app like Weepo is to significantly reduce the search costs of dating by actually bringing like-minded users together in the same place in one step. For what it’s worth, we also found this statement of interest from the N.Y. Post story: “’A lot of girls are going to the more high-end clubs’ like Tao, No. 8 and Marquee, which typically require stiff drink prices and steep covers, according to [Hod] Gerlitz. Young guys, meanwhile, gravitate toward no-cover bars—particularly those with cheaper drinks.”

Contagion theory of violence

Check out this provocative open-access paper titled Contagion in Mass Killings and School Shootings (Towers, et al., 2015). Here is an extended excerpt (footnotes omitted): “We fit a mathematical contagion model to the data sets, with model terms that take into account temporal trends due to possible exogenous non-contagion factors, and a contagion term that takes into account the fact that a school shooting or mass murder may temporarily increase the probability of a similar event in the immediate future. We model the contagion process assuming an exponential decay in contagiousness after an event. Contagion models have been applied to financial markets, spread of YouTube videos on social networks, burglary, civilian deaths in Iraq, and terrorist attacks, but this is the first instance in which these models have been applied in the context of mass murders and school shootings.” Hat tip: Tyler Cowen, via Marginal Revolution.

Markets, the regulation of data, and the future of low-wage work

Companies like Google, Facebook, and Uber have created new markets and improved our lives by reducing search costs, but at the same time, these firms collect massive amounts of data from their users. Who owns this data, and what legal duties do these firms owe to their users or to the public? Should the collection of user data be regulated in some form? (If yes, then by whom? Who would do the regulating?) These are hard questions, and a good place to start is this excellent essay by Brishen Rogers, a law professor at Temple University, on “the social costs of Uber” and other ride-sharing services. (Props go to Oscar Ruiz for bringing Professor Rogers’s paper to our attention.) Here is an overview of the paper:

This essay … argues that Uber’s success stems not (just) from regulatory arbitrage or other malfeasance, but from having created a far more efficient market for car-hire services. It then argues that Uber’s rise is cause for both optimism and pessimism. In addition to its obvious positive effects on consumer welfare, Uber’s partial consolidation of the car-hire sector and its compilation of data on passenger and driver behavior may enable Uber and regulators to ensure safety and root out discrimination against passengers with relative ease. In that regard, Uber may be an improvement over the existing taxi sector, which is quite difficult to regulate, though of course much depends on political will. Uber’s longer-term impact on labor standards is quite unclear, however, and it may have dark implications for the future of low-wage work more generally.
