  • David Evans has two good posts, an intro to eval for NGOs “Is My NGO Having a Positive Impact”  & one explaining that zero effect might be hiding more than you think.
  • Pacific Standard Magazine looks at what really happened to woolly mammoths, and not just them:

    There were mastodons, six-foot tall beavers, ground sloths the size of black bears, armadillos bigger than Volkswagen Beetles, American lions and cheetahs and camels, and saber-toothed tigers—to name just a few. Between 10,000 and 13,000 years ago, the Americas alone—once a zoo filled with enough wonders to put a modern African safari to shame—lost over 70 genera of large mammals.

The prevailing opinion used to be that climate change killed them, but that is giving way to an economic explanation, the tragedy (or problem) of the commons. When these potential sources of wealth aren’t owned, everybody has an incentive to hunt them and nobody to preserve them. Elephants hunted for ivory today face the same problem and the article discusses solutions from economics.

  • Alexandra Elbakyan, a researcher from Khazakstan, is making millions of academic papers available free.
  • A Cambridge Ph.D. student in Egypt studying labor and unions was abducted and killed.
  • Yale Ph.D. student William Schpero created a STATA module to notify your phone when your code is done running.
  • Not development related, but two really good podcasts to broaden your horizons:
    • Gimlet’s Sampler podcast searches out really compelling excerpts from other interesting podcasts, so far it’s been very good.
    • One episode of the Reply All podcast, excerpted by Radiolab, is the incredibly compelling story of a programmer whose son had cancer and turned the experience into a videogame.
  • UChicago’s summer institute on field experiments is accepting applications from young researchers.

And, the (still hypothetical) Equipay app lets you fix the wage gap by splitting the restaurant bill fairly. (h/t Planet Money)

Can political ideas drive development? My prediction for the next thought revolution in development circles

Everywhere I turn I keep seeing people writing about the way that ideas and ideology shape development paths: what political strategies get pursued, what institutions get put in place. Most of these are isolated examples. Only some of the scholars are aware of one another. Some examples:

  • Josh Simon at Columbia, a political philosopher, is considering how Americas-born “Creole” thinkers, like Bolivar or Alexander Hamilton, shaped the kind of political unions and nations that formed. Also here.
  • I have been re-reading an old favorite book, Coffee and Power, by Jeffrey Paige, which tries to understand why relatively similar countries in Central America took incredibly different political paths. Liberal ideologies and inventive, ideological politicians in the late 19th century play a big role in his explanation.
  • Dani Rodrik has tried to place ideology in the kinds of models economists are comfortable talking about, and suggests a political possibilities frontier that is often below the production possibilities frontier, that can both limit what options we pursue as a society, but also shows the role for ideology and innovative political entrepreneurs to change the system.
  • In international relations, the diffusion of norms and ideas is now one of the most predominant explanations for political change, such as democratization. See this famous piece by Martha Finnemore and Kathryn Sikkink.

A few years ago, when Acemoglu and Robinson wrote Why Nations Fail, they singled out “ideology” as one of the theories that simply can’t explain development paths. I mostly buy the Acemoglu and Robinson view of the world, and teach the book, but I remember thinking to myself at the time: “If I had to place bets on where the most interesting research will be, it’s where the new orthodoxy tells us we have to stop looking.”

More pointers welcome.

Technology giveth to Uber and technology will taketh away?

Adrian Chen in the New Yorker describes one man, Fabio Krasniqi, and his attempt to organize Laguardia airport Uber drivers after Uber suddenly dropped fares by 15%.

Bits and pieces of the piece made me wonder: Technology giveth to Uber but technology can taketh away?

New York has an estimated thirty thousand Uber drivers, and a while ago Krasniqi and some other LaGuardia drivers started a group on the messaging app WhatsApp called the Drivers Report, where they trade information about traffic and the level of demand at the airport.

…Krasniqi designed a flyer on his smartphone and ordered twenty thousand copies at a print shop near the airport. The other drivers chipped in.

..Now, in Lot 7, Krasniqi was trying to keep the previous day’s momentum going. He stood over a picnic table, scrawling the name of a Facebook page he had created on a piece of poster board. It was called Uber Drivers Report. In the hoarse bark of a coach at halftime, Krasniqi urged his audience to like and share the page to get the word out about upcoming protests.

There is still much room for the traditional social network.

Eventually, Dorjee, Krasniqi, and about a dozen other drivers from Lot 7 formed an informal committee to plan a protest the following Monday. They represent the many ethnic groups that comprise the approximately seven hundred drivers who regularly work out of LaGuardia: “I said, ‘Listen, guys, in order for us to be powerful and to be strong and for the drivers to trust exactly what we’re saying, we have to leave the door open to all communities,’ ” Krasniqi said.

…Each member of the committee reached out to well-connected members of his or her own ethnic community.

Plus fascinating bits about different union locals competing to represent them.

The downside of having chimp brains and just 140 characters: A theory of Internet nastiness

On a long car drive this weekend, I happened to listen to this brilliant This American Life podcast: If You Don’t Have Anything Nice to Say, SAY IT IN ALL CAPS. Stories of why otherwise nice people say awful things on the Internet.

Those of you following me on Twitter Thursday and Friday will understand why this was cathartic. (If not, don’t worry about it, it’s not the point of this post or a very big deal.)

Rather, in the midst of nastiness, @dadakim tweeted something that at first I found off topic: “This=sometimes how it feels to be a woman with an opinion on the internet.”

I will say this: If you are remotely skeptical of that statement, you should listen to the TAL podcast.

I am forced to update my theory of Internet nastiness. Previously I ascribed nastiness to the same instincts that make us nasty gossips. In haste, in irritation, and in private we tend to say things that we would never say in front a wider audience, or to a person’s face. For some reason people seem to engage their gossip brain on Facebook, Twitter, and blogs rather than their “I’m speaking to you directly” brain.

The Internet is curiously dehumanizing. You have to teach yourself not to write like that, and on the receiving side coach yourself not to read it too seriously (or at all). Both are difficult. For me the first is easier than the second.

I still buy my theory. But this isn’t quite sufficient to explain the frequency and maliciousness of attacks against women.

It’s tempting to look at the anecdote from TAL–a reformed troll who comes to understand how his insecurity feeds a loathing of women, and how the dehumanizing Internet lets him relieve his own anger without understanding the consequences. But deep-rooted misogyny seems like too simplistic an answer to be full or correct.

I am guessing many have thought about this subject and would be interested in pointers. Especially science on the subject.

How your city can create more criminals of its young men

Why do crime rates differ greatly across neighborhoods and schools? Comparing youth who were assigned to opposite sides of newly drawn school boundaries, we show that concentrating disadvantaged youth together in the same schools and neighborhoods increases total crime.

We then show that these youth are more likely to be arrested for committing crimes together — to be “partners in crime”.  Our results suggest that direct peer interaction is a key mechanism for social multipliers in criminal behavior.  As a result, policies that increase residential and school segregation will — all else equal — increase crime through the formation of denser criminal networks.

  • Priceonomics combines census data with historical accounts in a very interesting piece “The Great Migration: The African American Exodus from The South.” The conversations in the comments section have been really good as well (I also learned that we’re in the midst of a reverse migration back to the South).
  • UN peacekeeping troops from France and Georgia sent to help refugees in the Central African Republic are accused of rape there. More here and here.
  • In Ghana, regulators hope to merge the four separate mobile money platforms that exist now, but there is a dispute between banks and telecom companies over interest payments. The banks would like to return 100% of the interest to the customers while the telecom companies would like it returned to them, so they can take 20% of it, passing the rest back to the customers.
  • Normally, low-income students can send four sets of SAT scores to colleges free. Doubling this number to eight (which is very inexpensive to do) had a very impressive effect: 

Specifically, we estimate that inducing a low-income student to send one more score report, on average, increased on-time college attendance by nearly 5 percentage points and five-year bachelor’s completion by slightly more than 3 percentage points. The policy impact was driven entirely by students who, based on SAT scores, were competitive candidates for admission to four-year colleges.

  • Tim Harford has his top five economics podcasts to listen to in 2016 (and a reminder that some of our favorite individual episodes from 2015 are here).
  • And, telemarketers and scammers have been using internet calling with caller ID spoofing to avoid rules. Sometimes the conversation is driven by a human in a call center clicking on pre-recorded phrases to engage in a conversation. But one hero is trying to waste telemarketers’ time and drive up their costs with an AI interface designed to keep telemarketers on the phone as long as possible, and he’s letting other people use it too.

My favorite television of the past year


In order that I have enjoyed shows in the past year:

  1. The Expanse. A new space opera. The best since BSG, and maybe only second to that overall.
  2. Please Like Me, Season 2. Funniest show ever about a young gay man facing rejection, death, and mental illness. All the usual ingredients of comedy.
  3. Homeland Season 5. As a supposedly liberal intellectual I think I’m supposed to not like this show. But I do. Probably the best season since the first.
  4. Man in the High Castle. From the Phillip K Dick novel, about an alternate history where the Nazis and Japanese win WWII.
  5. Jessica Jones. Emotionally disturbed superheroes and villains. The best take on the genre.

I have yet to watch Narcos but I plan to. The only people who don’t seem to like this are Colombians, who think they got the history right but are angry that Escobar is played by a Brazilian.

What do you recommend?

The rainbow bagel is so wrong for so many reasons

I have only lived in New York for about nine years, so I’m not really in a position to decide who gets to be a New Yorker or not, but my vote would be to deport these people from the state. We’ll take more Syrian refugees, and the governor of Texas can grow fat on neon bagels for breakfast.

Via Business Insider. Hat tip to my sister in law, who lives in Ottawa with direct access to the incredible Montreal-style bagel, and should know better than to be enthused by this culinary travesty.

This is probably the best argument I’ve ever heard for admitting Syrian refugees, or really anyone


Developed by three young software-engineering students at the University of Iceland, it lets users instantly compare their lineage by bumping their mobile devices together. The app includes an “incest-prevention alarm,” says Arnar Freyr Adalsteinsson, one of the developers. “When you bump, it shows your nearest common ancestors. If you bump with someone who’s too closely related, you get an alarm sound and a text warning.”

That’s right, a country where people are so similar you need a mobile app to tell you if your drunk booty call is a relative.

Four reasons why buying houses is overrated

Alex Tabarrok gives us two reasons

Housing is overrated as a financial investment. First, it’s not good to have a significant share of your wealth locked into a single asset. Diversification is better and it’s easier to diversify with stocks. Second, unless you are renting the basement, houses don’t pay dividends. Stocks do. You can hope that your house will accumulate in value but don’t count on it. Indeed, you should expect that as an investment your house will appreciate less than does the stock market.

…Another problem with houses is that home ownership locks people to location making it harder to move for jobs. The problem is especially severe because no one likes to sell at a “loss” even when it is rational to do so. So when jobs disappear and home prices fall instead of moving, people hold on for too long just hoping that things will get better.

I would add one more: People who own seem to spend a LOT of time on their weekends and holidays doing repairs and maintenance. If this is something you enjoy, great. If you would rather spend time with family, read, work, or Netflix binge, then it’s not so fantastic. Personally, my marginal value of leisure is high. I don’t even like thinking about my apartment or what needs to be done.

Alex highlights some of the benefits of housing. Some people like them a lot (or have been socialized to), and there are tax breaks. Plus so much of life in America is structured around home buying, such as public schooling.

I would add “forced savings”. If you are the kind of person who does not invest first spend later, then your mortgage forces you onto an intensive savings plan (in an albeit suboptimal investment).

So, basically, the best argument for houses is “distortions and weakness”.

I suspect some readers will still say things like “but housing is historically a great investment!”. I’m not sure they are thinking in real terms, and I do not think they are comparing it to historical stock market returns. And I am guessing people selectively remember the houses that appreciated, not the ones that stayed mainly flat. It’s like making the case for stocks based on people who bought Apple in 1987.

Surely someone has done the numbers here. Any pointers?

How J.K. Rowling just gave everyone an inadvertent lesson in statebuilding


Harry Potter author J.K. Rowling’s website made a big announcement over the weekend: there are wizarding schools in the U.S., Japan, and… Africa:

Although Africa has a number of smaller wizarding schools (for advice on locating these, see introductory paragraph), there is only one that has stood the test of time (at least a thousand years) and achieved an enviable international reputation: Uagadou. The largest of all wizarding schools, it welcomes students from all over the enormous continent. The only address ever given is ‘Mountains of the Moon’; visitors speak of a stunning edifice carved out of the mountainside and shrouded in mist, so that it sometimes appears simply to float in mid-air.

The scholarly Twitter outcry was quick in coming:

To Naunihal’s surprise, he got a quick reply from the author herself:

Uganda! My first gleeful thought: How pissed off is Rwandan President Paul Kagame about THAT? The Potter books are surely banned by this morning.

My second thought was, before anyone gets too upset about Africa having the only non-national school, did you not read your Jeffrey Herbst? He has one of the classic books on statebuilding. I’m actually teaching it tomorrow. Here is the article version (gated, sorry).

Whereas Europe and Japan developed states early on, geography conspired against state development in Africa until it was imposed by colonialism. Coherent states with national identities and defined boundaries were driven by competition and war in densely populated parts of the earth. If your climate, geographic barriers, soils, and what not prevented sharing technologies, trade, intensifying agriculture, and what not, then you more seldom developed extra food to support an elite or priestly caste to control the rest of the population. At least, not enough of them that they abut one another and constantly fight until the weaker proto-states are weeded out.

Without that war-making, and technologies that gave large states an advantage over other kinds of organization, much of Africa had a different form of politics. So, voila, is it so surprising that a thousand-year old school would be pan-African, throwing off the imposition of colonial boundaries?

So what we really want is a historical prequel, Harry Potter meets Mahmood Mamdani and Crawford Young, as Voldemort’s great-grandfather co-opts the Uagadou elite, developing a system of evil indirect rule. The question is which Independence leader was secretly the bearer of noble juju?

A must-see video on immigration that will make you laugh, cry, cry-laugh, and think

People occasionally email me articles or videos that might interest me. I love getting these. As sales pitches go, however, an email labeled “Comedy Talk on Integration” is not an obvious win. “This is a comedy talk I gave based of the work of Michael Clemens, Lant Pritchett, and others.” wrote Steve Gerben.

I love Michael and Lant, but that’s not exactly clickbait.

But I happened to be at the gym, bored with a podcast, and trying to find something to keep me on the treadmill more than five minutes. “Raw material to tease Michael about a fanboy” seemed like a good investment. So I gave the video a try.

Brilliant. Steve Gerben is a talented man. I want him to teach my class, or start a MOOC. I want him to teach me how to teach like this. Watch it. And send it to your Republican relatives and Facebook friends.

More important, updated data show that communities served by the “go-getters” are doing better on key health benchmarks such as facility-based childbirth, breast-feeding, vaccinations and nutrition. Based on these findings, the Zambian government changed its recruitment advertising as it looks to expand its health-worker program.

  • The idea of a social safety net that guarantees a “basic income” has been gathering interest. The Dutch city of Utrecht is working with academics to set up an experiment comparing different forms, and the Silicon Valley tech incubator Y-Combinator is seeking someone to work full time on a five-year experiment giving a group of people in the U.S. a basic income (deadline for applications is Feb 15).

What the New England Journal of Medicine has in common with my 2- and 4-year old children

i gather academic Twitter is exploding over a New England Journal of Medicine editorial that worries that:

a new class of research person will emerge—people who had nothing to do with the design and execution of the study but use another group’s data for their own ends, possibly stealing from the research productivity planned by the data gatherers, or even use the data to try to disprove what the original investigators had posited. There is concern among some front-line researchers that the system will be taken over by what some researchers have characterized as “research parasites.”

This is rightly being called out as anti-scientific. Maybe the best response so far was David Shaywitz:

I was delighted to see this editorial.

Not because I agreed with it–my heart is truly with the data scientists–but because I was grateful that someone had the courage to articulate a perspective I’ve come to believe is shared by the vast majority of academic researchers, but publicly voiced by no one–until now.

I see this data hoarding instinct all the time. I also see my two toddlers gather all their toys in their arms at once and insist to the other “I AM PLAYING WITH ALL OF THEM.”

Similarly, I see authors and corporations try to extend copyright again and again. This greed instinct is natural and motivates data collection and a good deal of work. But innovation means it needs to be balanced against public use.

I think the days you can mine a dataset for five years (or forever) before sharing are nearly over, and good riddance. You’ll find most of my data online with publication, if not beforehand.

Hat tip to David Lam.
