A couple years ago NPR's Planet Money podcast had an episode about Somali pirates. (The pirate part starts at 9:35). There was all sorts of interesting stuff about division of labor, allocation of shares, pirate venture capital, etc. Some of this paralleled early modern piracy (as given a scholarly analysis in Peter Leeson's work and a romantic perspective in innumerable books and movies since Treasure Island) but in other respects it's very different. In particular, whereas early modern piracy was mostly about seizing cargo and the crews were left alone if they surrendered promptly, Somali piracy is more similar to piracy in antiquity in that it's basically maritime kidnapping. The typical instance of Somali piracy isn't that different from what a young Julius Caesar experienced when he was kidnapped by pirates and held for ransom on his way home from political exile in Asia Minor. One interesting detail in Plutarch's report is that, "When these men at first demanded of him twenty talents for his ransom, he laughed at them for not understanding the value of their prisoner, and voluntarily engaged to give them fifty."
It's not entirely clear if we should take Plutarch's report at face value (he also tells us that Caesar constantly insulted his captors as being, for instance, too uncivilized to appreciate his poetry) but for the sake of argument let's accept that Caesar rather brashly gave away too much information in the game of price discovery. According to a hostage negotiator quoted by This American Life, giving away this information is apparently typical of hostages and is counter-productive to their release as it narrows the bid-ask spread. Economists would describe hostage negotiation as a bilateral monopoly price negotiation that is structurally just a special case of chicken. That is, unlike a barrel of oil or a freight car full of soybeans which can trade on an extremely liquid market with innumerable buyers and sellers, a hostage has exactly one seller (the kidnappers) and exactly one buyer (the employer and/or family of the hostage). When there is only one buyer, the opportunity cost for ransoming the hostage is zero. Likewise, the employer and/or family has no realistic alternative means to recover the hostage. In order for everybody to walk away happy, we need a cooperate-cooperate outcome: the kidnapper has to give up the hostage and the employer/family has to give up a ransom. This structure also characterizes art theft, which in practice is not a matter of fencing art on the black market but ransoming art to a museum's insurance company.
If we model a bilateral monopoly negotiation only two things should matter. The first is, as always in a game of chicken, the willingness to accept failure. The more willing you appear to walk away, the more bargaining power you have. In a more protracted game this can cash out as willingness to delay which we can treat as a defect-defect outcome on the installment plan. In fact in the Planet Money episode on Somali piracy, the hostage's party did balk and break off negotiations for weeks at a time until the pirates were willing to come down on price.
The other thing that should matter is the capacity to pay. If the pirate knows for an absolute fact that the hostage's people simply can't raise more than a million dollars then it would be pointless for them to demand two million dollars. Of course there is an issue of information asymmetry in that the hostage's party has much better information on its assets than do the pirates and so the pirates may be skeptical of the hostage's party pleading poverty (especially if the hostage has foolishly told them how much money they can get). We see this at work in the TAL story's point that kidnapping insurance holds the condition that you can't tell anyone you have kidnapping insurance.
Here's something that the econ model tells us shouldn't matter: the going rate. In normal markets the going rate matters, but only because it provides the opportunities for substitutes and this creates the "law of one price." For instance, when I go to a grocery store and see a loaf of bread for $4 I won't buy it. An economist would say I forgo this purchase because I know perfectly well that the going rate for a loaf of bread is about $2.25 and so I can go elsewhere and get bread cheaper. Similarly if I go to the Honda dealer to buy a Honda Accord, it is relevant for me to mention price quotes offered by other Honda dealers for an Accord or even how much Toyota dealers ask for a Camry because it is entirely credible that I'll walk off the lot and go to rival car dealers offering very close substitutes for this dealer's cars. However if my sister is locked in a basement in Ciudad Juarez and the kidnappers can credibly commit to not letting her go unless I raise $x, it is completely irrelevant that in the past kidnappers accepted ransoms of $x/2 since I don't have the relatively good fortune of dealing with a kidnapper who demands $x/2 but am stuck with one who demands $x. There are no other places where I can buy the freedom of my sister and so the only price that matters is the one being demanded by her particular kidnappers. (Note to any cartels reading this: I don't have a sister).
And nonetheless, much like how most people who haven't studied statistics balk at the idea that the ratio of sample size to population size is irrelevant to statistical inference, people seem to have a strong intuition that the "market price" is relevant to a bilateral monopoly even though the whole idea of a bilateral monopoly is that there is not really a market but only a series of discrete one-off transactions. In the absence of substitutability, "comparable" transactions are irrelevant as they don't imply opportunity cost. This is the main thing I found so fascinating about the Planet Money episode, over and over again the hostage's party balked at the pirates demands as unreasonable in being out of line with the "market price." We only get the pirates' story second hand, but apparently at no point did they explain to the hostage's party that "market price" doesn't really exist in a bilateral monopoly. (Maybe Mogadishu University needs a better econ department).
There are two ways, which are only partially incompatible, to look at why people insist that there is a market price. The simple model is to see us as making Bayesian inferences about the price the other party is willing to accept. If a pirate asks me for $10 million when I know that previous ransoms for similar hostages from similar pirates were about $1 million, I face two possibilities. It may be that I'm facing an usually greedy or unreasonable pirate and $10 million really is the price from which he will not budge. However it seems more likely that I'm dealing with a regular pirate, who like most pirates in the past will ultimately settle for about $1 million but who is just floating a high initial figure in case I'm especially bad at this. In this sense the distribution of prices for similar transactions may not be directly relevant in the sense of providing opportunities for substitution (or the credible threat to avail myself of them) but it is still relevant as information about the zone of possible agreement. This is consistent with the Planet Money story in that Filipinos are cheaper to ransom than Europeans by an order of magnitude. Presumably this reflects Bayesian inference on the part of the pirates from the hostage's nationality as to how much the hostage's party should be able to raise. Alternately we could imagine that pirates always start with the same bargaining position but the Filipinos are less able to pay and so the pirates eventually reach this through ad hoc price discovery on a case-by-case basis. This strikes me as implausible though and I think pirates probably learned pretty quickly what they can reasonably expect for each nationality.
This is a nice explanation and it has the appeal of bending but not breaking the economic model of the actor, but it's not clear how seriously we want to take it and even if it's ultimately true it may not reflect the subjective experience. For instance, one of the main explanations for racial discrimination is that it reflects Bayesian inference about aspects of human capital that aren't readily observable. This model was devastated by Devah Pager's audit study showing that employers prefer to hire white men with a criminal record rather than black men without a criminal record, whereas the "statistical discrimination" model predicts that ascriptive discrimination should be weaker than and diminish greatly in the presence of information about relevant traits at the individual level. In the wake of the Pager study the best case you can make for the statistical discrimination model is that our intuitions are Bayesian in the aggregate but are too low level for us to override with directly relevant information (or, for that matter, with the conscious desire to avoid stereotyping on legal or ethical grounds). It's not unlike the argument that evolution made sex feel good so that we will propagate our genes, but it still feels good when you use birth control. So we might prefer a model that is ultimately consistent with people using prevailing price as information in bilateral monopoly negotiations, but is proximately and subjectively more about meaning.
Although the discipline of economics has many valuable things to teach us about how markets work, especially in the long-run, the subjective experience of someone bargaining does not necessarily reflect thinking through how a rational actor would apply price theory (competitive markets) or game theory (monopolistic markets) to the situation. Rather people take moralized approaches to exchange and seem to apply various relational models to exchange, which includes not only market exchange but also gift exchange, patron-client ties, and primitive communism. Moreover, even when people accept that a situation is one of market exchange it does not come naturally to think of price like modern economists think of it, as "market clearing." Rather much as people intuitively expect physical objects to behave by Buridan's impetus rather than Newton's inertia, people's intuitive notions about price can have less to do with how economics thinks of it than how Aristotle, Aquinas, and Marx thought of it, as "just price" or "fair price." We see the Aristotelian/scholastic/Marxist understanding of price institutionalized in price controls and laws against gouging. The intuition many people seem to feel is that the long-run prevailing price has moral weight and deviations from this price (as for instance in a supply or demand shock leading to "gouging") are immoral. Hence historical bread riots often involve not exactly stealing food but rather mobs enacting vigilante price controls. Most recently we saw this is in a class action lawsuit against concession prices in movie theaters. As an American and someone who studies exchange professionally, economics comes naturally enough to me that my immediate reflex to this story is to think this guy needs to understand two-part tariffs and tell him if he doesn't like the theater's prices nobody is forcing him to go there or to eat once he arrives. However the fact that somebody felt sufficiently indignant to sue over being offered the opportunity to buy a bucket of popcorn for $6 shows us that the perspective assumed by academic economics doesn't necessarily come naturally to people. Similarly, when the hostage's party is negotiating a ransom with pirates both the pirates and hostages may be behaving in ways that are ultimately consistent with a game of chicken under conditions of bounded rationality and Bayesian inference about asymmetric information, but in the immediate subjective sense they may simply be feeling that the recent run of ransoms sets an expectation of what it is fair to pay for this particular hostage.
Oh, and one more thing about Caesar. Plutarch tells us that after he was ransomed he got some ships, raided the pirates, and had them all crucified.
The Islamic State is no mere collection of psychopaths. It is a religious group with carefully considered beliefs, among them that it is a key agent of the coming apocalypse. Here’s what that means for its strategy—and for how to stop it.
What is the Islamic State?
Where did it come from, and what are its intentions? The simplicity of these questions can be deceiving, and few Western leaders seem to know the answers. In December, The New York Times published confidential comments by Major General Michael K. Nagata, the Special Operations commander for the United States in the Middle East, admitting that he had hardly begun figuring out the Islamic State’s appeal. “We have not defeated the idea,” he said. “We do not even understand the idea.” In the past year, President Obama has referred to the Islamic State, variously, as “not Islamic” and as al-Qaeda’s “jayvee team,” statements that reflected confusion about the group, and may have contributed to significant strategic errors.

A recent Brookings study suggests that brains and drive have more to do with lifelong success than family wealth. But there's a big catch.
I know, I know, you'd rather be born smart and rich (and charming, and with a lustrous head of hair, and a voice like Michael Bolton's). But if you had to choose? Chances are, your answer depends on whether you think the U.S. economy is a meritocracy—that intelligence and ambition are more important to lifelong success than the circumstances of your birth.
A recent Brookings paper gives reasons for optimism. Over the long term, it finds, smart kids earn more than rich kids. But sadly, there's a big catch.
The Brookings paper looked at the relationship between brains, motivation, and economic mobility among a group of youth the government began tracking in 1979. Here's the executive summary: If they were bright and driven, poor kids stood a decent chance of becoming upper-middle-class, or better. Of low-income teens who scored in the top third of test-takers on the Armed Forces Qualification Test (on the far left in green), more than 40 percent made it to the top two income quintiles by adulthood. Meanwhile, dimwitted children of affluence generally fell down the economic ladder. Among high-income teens who scored in the bottom third of AFQT takers (on the far right in orange), more than half ended up in the bottom two income quintiles.
The Republican frontrunner has surged in the polls by taking a tough stance on immigration—and if critics want to stop him, that’s what they need to attack.
A new round of attack ads are heading Donald Trump’s way, some from John Kasich’s campaign and the super PAC backing him, and more in the future from an LLC created specifically to produce anti-Trump messages.
New Day for America’s 47-second ad splices together some of the Republican front-runner’s most awkward video moments: his suggestion he might date his daughter, his claim of “a great relationship with the blacks.” The Kasich campaign’s ad turns Martin Niemöller’s famous words “nobody left to speak for me” into a warning from one of John McCain’s fellow Hanoi Hilton POWs that a Trump presidency is a threat to freedom.* John Kasich’s Twitter account has fired direct personal challenges to the famously thin-skinned mogul.
In the name of emotional well-being, college students are increasingly demanding protection from words and ideas they don’t like. Here’s why that’s disastrous for education—and mental health.
Something strange is happening at America’s colleges and universities. A movement is arising, undirected and driven largely by students, to scrub campuses clean of words, ideas, and subjects that might cause discomfort or give offense. Last December, Jeannie Suk wrote in an online article for The New Yorker about law students asking her fellow professors at Harvard not to teach rape law—or, in one case, even use the word violate (as in “that violates the law”) lest it cause students distress. In February, Laura Kipnis, a professor at Northwestern University, wrote an essay in The Chronicle of Higher Education describing a new campus politics of sexual paranoia—and was then subjected to a long investigation after students who were offended by the article and by a tweet she’d sent filed Title IX complaints against her. In June, a professor protecting himself with a pseudonym wrote an essay for Vox describing how gingerly he now has to teach. “I’m a Liberal Professor, and My Liberal Students Terrify Me,” the headline said. A number of popular comedians, including Chris Rock, have stopped performing on college campuses (see Caitlin Flanagan’s article in this month’s issue). Jerry Seinfeld and Bill Maher have publicly condemned the oversensitivity of college students, saying too many of them can’t take a joke.
Why are so many kids with bright prospects killing themselves in Palo Alto?
The air shrieks, and life stops. First, from far away, comes a high whine like angry insects swarming, and then a trampling, like a herd moving through. The kids on their bikes who pass by the Caltrain crossing are eager to get home from school, but they know the drill. Brake. Wait for the train to pass. Five cars, double-decker, tearing past at 50 miles an hour. Too fast to see the faces of the Silicon Valley commuters on board, only a long silver thing with black teeth. A Caltrain coming into a station slows, invites you in. But a Caltrain at a crossing registers more like an ambulance, warning you fiercely out of its way.
The kids wait until the passing train forces a gust you can feel on your skin. The alarms ring and the red lights flash for a few seconds more, just in case. Then the gate lifts up, signaling that it’s safe to cross. All at once life revives: a rush of bikes, skateboards, helmets, backpacks, basketball shorts, boisterous conversation. “Ew, how old is that gum?” “The quiz is next week, dipshit.” On the road, a minivan makes a left a little too fast—nothing ominous, just a mom late for pickup. The air is again still, like it usually is in spring in Palo Alto. A woodpecker does its work nearby. A bee goes in search of jasmine, stinging no one.
Nobody’s focused on winning the peace. That’s a big problem.
In August 1941, Winston Churchill and Franklin Roosevelt met off the coast of Newfoundland to outline a shared vision for the post-World War II era. The British prime minister was so thrilled to see the American president that, in the words of one official, “You’d have thought he was being carried up into the heavens to meet God.” The two countries issued the Atlantic Charter, which sought “a better future for the world” through the principles of self-determination, collective security, and free trade. The United States hadn’t even entered the war yet, but it was already focused on winning the peace. The endgame was not just the defeat of the Axis powers, but also the creation of a stable global order, in which World War II would be the last world war.
An entire industry has been built on the premise that creating gourmet meals at home is simple and effortless. But it isn’t true.
I write about food for a living. Because of this, I spend more time than the average American surrounded by cooking advice and recipes. I’m also a mother, which means more often than not, when I return from work 15 minutes before bedtime, I end up feeding my 1-year-old son squares of peanut-butter toast because there was nothing in the fridge capable of being transformed into a wholesome, homemade toddler meal in a matter of minutes. Every day, when I head to my office after a nourishing breakfast of smashed blueberries or oatmeal I found stuck to the pan, and open a glossy new cookbook, check my RSS feed, or page through a stack of magazines, I’m confronted by an impenetrable wall of unimaginable cooking projects, just sitting there pretending to be totally reasonable meals. Homemade beef barbacoa tacos. Short-rib potpie. “Weekday” French toast. Make-ahead coconut cake. They might as well be skyscraper blueprints, so improbable is the possibility that I will begin making my own nut butters, baking my own sandwich bread, or turning that fall farmer’s market bounty into jars of homemade applesauce.
CRISPR can finally tell us which human genes are essential—and which matter specifically to cancer cells.
Humans have between 20,000 and 25,000 genes, but which of these really matter? Which are essential, and which are merely optional add-ons?
It’s crazy to me that we still don't know, even though it’s been almost 15 years since the first draft of the human genome was published. Partly, the problem is a technological one. The best way of working out if a gene is essential is to disable it and see what happens, and “we just didn’t have a good way of systematically manipulating genes in humans cells,” says Jason Moffat from the University of Toronto. Sure, scientists have been able to tinker with individual genes, but working through them all, and knocking them out one by one, has been nigh-on impossible.
