Using the Twitter name “@chiefkariuki“, Kariuki sends messages to over 15,000 of the 28,000 people who live in Lanet Umoja. They include village elders, community and church leaders, the police, youth and women’s groups, and school principals.

When an incident occurs, the victims or eyewitnesses send text messages to the chief, describing the nature of the incident, the place and the nearest known landmark. The chief then broadcasts his instructions to the community through Twitter.

While not everyone has 3G-enabled cellphones here, many just subscribe to follow Kariuki’s account through their local service providers and receive his tweets by text message.

When the chief sends out a message, in a matter of seconds the entire location goes into action as directed.

Do any post-conflict elections serve as an effective tool for conflict resolution? The existing literature suggests that they usually do not, yet much of the international community actively endorses and supports elections in this role. In contrast to other studies, I show that post-conflict elections can help terminate conflict and promote lasting peace. Post-conflict elections are useful in resolving conflict when militant groups and governments both participate as political parties.

So, why do both sides engage in certain post-conflict elections? I argue that the end of the Cold War has allowed these inclusive elections to become a mechanism for resolving conflict by facilitating international involvement in guaranteeing a peace deal above and beyond military intervention. Specifically, governments and militant groups often contest elections to commit themselves to a negotiated settlement in order to end the fighting through the engagement of an international actor that can then more easily monitor and sanction violations of the deal.

A new paper by Aila Matanock.

We present evidence from nearly 14,000 American Red Cross blood drives and from a natural field experiment showing that economic incentives have a positive effect on blood donations without increasing the fraction of donors who are ineligible to donate. The effect increases with the incentive’s economic value. However, a substantial proportion of the increase in donations is explained by donors leaving neighboring drives without incentives to attend drives with incentives

Jourdan’s full reply is worth posting in full.

Dayton, Ohio,

August 7, 1865

To My Old Master, Colonel P.H. Anderson, Big Spring, Tennessee

Sir: I got your letter, and was glad to find that you had not forgotten Jourdon, and that you wanted me to come back and live with you again, promising to do better for me than anybody else can. I have often felt uneasy about you. I thought the Yankees would have hung you long before this, for harboring Rebs they found at your house. I suppose they never heard about your going to Colonel Martin’s to kill the Union soldier that was left by his company in their stable. Although you shot at me twice before I left you, I did not want to hear of your being hurt, and am glad you are still living. It would do me good to go back to the dear old home again, and see Miss Mary and Miss Martha and Allen, Esther, Green, and Lee. Give my love to them all, and tell them I hope we will meet in the better world, if not in this. I would have gone back to see you all when I was working in the Nashville Hospital, but one of the neighbors told me that Henry intended to shoot me if he ever got a chance.

I want to know particularly what the good chance is you propose to give me. I am doing tolerably well here. I get twenty-five dollars a month, with victuals and clothing; have a comfortable home for Mandy,—the folks call her Mrs. Anderson,—and the children—Milly, Jane, and Grundy—go to school and are learning well. The teacher says Grundy has a head for a preacher. They go to Sunday school, and Mandy and me attend church regularly. We are kindly treated. Sometimes we overhear others saying, “Them colored people were slaves” down in Tennessee. The children feel hurt when they hear such remarks; but I tell them it was no disgrace in Tennessee to belong to Colonel Anderson. Many darkeys would have been proud, as I used to be, to call you master. Now if you will write and say what wages you will give me, I will be better able to decide whether it would be to my advantage to move back again.

As to my freedom, which you say I can have, there is nothing to be gained on that score, as I got my free papers in 1864 from the Provost-Marshal-General of the Department of Nashville. Mandy says she would be afraid to go back without some proof that you were disposed to treat us justly and kindly; and we have concluded to test your sincerity by asking you to send us our wages for the time we served you. This will make us forget and forgive old scores, and rely on your justice and friendship in the future. I served you faithfully for thirty-two years, and Mandy twenty years. At twenty-five dollars a month for me, and two dollars a week for Mandy, our earnings would amount to eleven thousand six hundred and eighty dollars. Add to this the interest for the time our wages have been kept back, and deduct what you paid for our clothing, and three doctor’s visits to me, and pulling a tooth for Mandy, and the balance will show what we are in justice entitled to. Please send the money by Adams’s Express, in care of V. Winters, Esq., Dayton, Ohio. If you fail to pay us for faithful labors in the past, we can have little faith in your promises in the future. We trust the good Maker has opened your eyes to the wrongs which you and your fathers have done to me and my fathers, in making us toil for you for generations without recompense. Here I draw my wages every Saturday night; but in Tennessee there was never any pay-day for the negroes any more than for the horses and cows. Surely there will be a day of reckoning for those who defraud the laborer of his hire.

In answering this letter, please state if there would be any safety for my Milly and Jane, who are now grown up, and both good-looking girls. You know how it was with poor Matilda and Catherine. I would rather stay here and starve—and die, if it come to that—than have my girls brought to shame by the violence and wickedness of their young masters. You will also please state if there has been any schools opened for the colored children in your neighborhood. The great desire of my life now is to give my children an education, and have them form virtuous habits.

Say howdy to George Carter, and thank him for taking the pistol from you when you were shooting at me.

From your old servant,

Jourdon Anderson.

As far as I can tell, my students have pretty much the same experience.

The premise: a callous professor of poetry receives treatment for ovarian cancer. Played by a former Sex in the City cast member.

You can see the source of my low expectations.

The author, who won a Pulitzer for the play in 1999, has yet to produce another work and continues her job as a primary school teacher in Georgia.

If you are not in New York, there is a television version that is apparently good.

In recent years, a trend has emerged in the behavioral sciences toward shorter and more rapidly published journal articles. These articles are often only a third the length of a standard paper, often describe only a single study and tend to include smaller data sets. Shorter formats are promoted by many journals, and limits on article length are stringent — in many cases as low as 2,000 words.

This shift is partly a result of the pressure that academics now feel to generate measurable output.

…But some researchers contend that the trend toward short articles is also better for science. Such “bite size” science, they argue, encourages results to be communicated faster, written more concisely and read by editors and researchers more easily, leading to a more lively exchange of ideas.

…We believe, however, there are a number of serious problems with the short-article format.

The article is here. I share their suspicions, though the article itself provides more accusations and suppositions than actual evidence. A stronger case can likely be made.

I’m preparing an article for a medical journal with psychologist colleagues and am struggling with the word limit. Economics and political science articles may drag on, and be fewer in number, but with that space they explore the nuance and limitations and validity. Plus context.

I would not give it up, but on the contrary, prefer to see more packed into the same lengthy space.

First, lest anyone mistake this blog for a quality news and analysis outlet, let me remind everyone I blog hurriedly in my nearly non-existent spare time, and do not think much before I write. For if I did, there would not be a blog post every day.

Nonetheless, there is thoughtless and then there is reckless. Sometimes I am the latter.

We’ll start with the minor bit: Freakonomics departed from the NY Times at least a year ago.

More importantly, a clarification and apology. I’ve received links and hat tips from both blogs in past years. Freakonomics references sources and hat tips routinely, but on balance refrains from hyperlinking. To link or not to link? Politeness will remain in the eye of the beholder. But I should not call that plagiarism, or allude that. It’s a serious charge not to be thown around lightly, as I did. For that I apologize.

Finally, a small stand. What irked me is far less serious than plagiarism, but not ignorable. It’s the impression that large and profit-oriented blogs, especially ones that are affiliated (past or present) with media giants are less generous with attribution than the rest of the world.

On some blogs, intermediate sources are not hat-tipped, a practice which is bad manners at best, and worse things at worst. On others, like Freakonomics, hat tips exist but are merely unhyperlinked. The latter discussion is perhaps not worth the bits and bytes it involves. Unhyperlinked is not even a word. I’ll let readers be the judge. But the former offense deserves more attention.

Why spend more blog space on such frivolous things? No good reason. On this occasion, I started it and I should fess up when I overstate myself, or falsely accuse.

Also, I have an overdeveloped sense of justice, which often pushes me in the right direction, but sometimes leads me along silly and fruitless paths, such as accosting strangers on New York City sidewalks for littering, or (more successfully) trying to bring order to Dubai airport lines when hundreds of people are jumping queues during a 4am rush.

I will admit: I still get a great sense of satisfaction from the memory of hundreds of people from as many nations meekly looking ashamed and falling back into line. How should I feel looking back on this episode? Reader opinions welcome.

I regularly read at least two big blogs run by newspapers — Freakonomics at the NY Times and Ideas Market at WSJ. They find a wonderful sampling of things across the web.

What’s interesting: they seldom say where they find their material. The bloggy custom of hat tipping is nearly absent. Once in a while Freakonomics gives a blog hat tip, but (oddly) they never actually hyperlink.

What’s the deal? One guess: the newspapery-blog-powers-that-be don’t want people leaving the site.

Impolite? Yes. Nefarious. Possibly. Plagiarizing? I’d ding my students if they did this so regularly and egregiously.

I have been the “victim” on more than one occasion, but not for some time. I don’t think that’s my motivation for this post. I don’t really care about the traffic. Rather, I see other blogs and sites I like become “victims” about every other week. Now my overdeveloped and misdirected justice and courtesy bones ache every time I read the offending blogs.

Reader thoughts and solutions?

Boycott Ideas Market and Freakonomics?

Some might think the question trivial, but I find these things symbolically important to the outside, as well as the inside. One of the worst transgressors in my mind is the World Bank, frequenter of business class and 5-star hotels–possibly more than any organization in the world.  That has to shape organizational people and practice, and not necessarily in a good way. (See my diatribes here and here).

Duncan gets many good, serious responses. No one brings up the issue that most people only go into humanitarian aid in order to do things like skinny dip with other thirty-something single do-gooders.

Nonetheless, I agree wholeheartedly with his winning comments. I particularly admire B and D.

Calvin: ‘Use the pool but don’t enjoy it’

Ros: ‘How we all agonize that we are not Gandhi’

But by popular acclaim, the prize for best comment goes to Matt for this gem:

A) Form a swimming pool collective with a rotating chair, with use of the pool to be voted on every week. Pool to be funded by bake sale at the local international school.

B) Divide the pool surface area into 100 square use rights – sell rights to the staff and/or guests, who are only allowed to swim within their allotted area, unless allowed to by other freeholders. Let residents buy and sell these rights to each other and let the market reach an efficient outcome

C) Let NGO workers use the pool, but constantly make them feel guilty about it: surround the pool with posters of photos from recent/ongoing drought. Actually, this could be a win win situation – if you run into anyone who seriously objects to the idea of Oxfam using a pool, let *them* stand on the side and heckle the swimmers.

D) Randomly allocate 50% of your guests with passes to the pool. Use pre and post survey data on stress levels, health, etc to evaluate the actual impact of pool usage. If you’re concerned about financial viability, charge a high price and then randomly distribute vouchers of varying levels to the treated group to tease out the demand curve for pool usage.

Following the Academy Award nominations earlier this week, we introduce the Exploiting Africa Academy Award (EAAA) nominations to recognize films who do the best against stiff competition to portray the most insulting and exploitative images of Africans, usually being heroically saved by some white people.

Machine Gun Preacher. This one is so exemplary that it inspired the EAAA in the first place. A commercial film based on a violent ex-con turned violent Christian who goes to central Africa to shoot bad guys and rescue any children still alive after the cross-fire. Principal white saviors : based on “true(?)” story of ex-biker-gang-member Sam Childers, supported in the movie by a beautiful model playing his ex-biker-gang-member-wife.

The Reckoning. About how the International Criminal Court protects African females and children against male African killers. Principal White Savior: Luis Moreno-Ocampo.

Darfur. About how Western correspondents protect African females and children against male African killers. Principal White Saviors: macho journalists supported by one attractive female journalist.

The Vice Guide to Liberia. OK it’s actually a web-based TV series from the Vice media empire, but it’s so horrifically exploitative (baby cannibalism, enough said), we had to include it. Principal White Savior: the Vice correspondent , although it’s very unclear how he’s saving anyone but himself.

An older classic:

Blood Diamond.  Educated the movie-going audience about the acronym TIA to be used whenever anything horrible happens in the movie — “This Is Africa”.Principal white saviors: mercenary and smuggler Leonardo di Caprio supported by gorgeous journalist Jennifer Connelly.

You can vote here. Or add your own nomination.

In the meantime, others have been forecasting more weighty matters:

Hunch then looks for statistical correlations between the information that all of its users provide, revealing fascinating links between people’s seemingly unrelated preferences. For instance, Hunch has revealed that people who enjoy dancing are more apt to want to buy a Mac, that people who like The Count on Sesame Street tend to support legalizing marijuana, that pug owners are often fans of The Shawshank Redemption, and that users who prefer aisle seats on planes “spend more money on other people than themselves.”

From “How Visa predicts divorce” in the Daily Beast.

Three of the Hunch forecasts above fit my profile.

It is entertaining and pleasing to watch. It avoids most of the opportunities for cliche. The Hawaiian soundtrack is original. George Clooney does an excellent rendition of George Clooney. Ho hum.

Usually a good litmus test for a character-driven story is: “Would I feel much emotion if one of the characters were hit by a bus?” In this case, not really. There is no sense they are real or interesting and hence worthy of attachment.

You might think “What’s the big deal? It’s a Hollywood production, so what did you expect?” I agree. But when you have a baby, film-going is much more difficult, in part because the price of a babysitter is only slightly less absurd, for the value, than the theater popcorn and soda. So the critically acclaimed films get your hopes a little higher, and more likely to be dashed.

I think I probably should have gone to see Once Upon A Time in Anatolia, even if it the most boring trailer ever. And Tyler Cowen tells me 24 hours too late that I should have seen A Separation.

Focusing on countries whose largest, or primate, city is also a port, I find that as the price of oil increases from $25 to $97 (as it did between 2002 and 2008), if city A is 465 kilometers (1 standard deviation) farther away from the primate than initially identical city B, its economy is roughly 6 percent smaller than city B’s at the end of the period. At a differential of 2360 kilometers, the largest in the data, this rises to 32 percent. I then determine that this effect falls disproportionately on cities that are connected to the primate by paved roads, most likely because they are initially more engaged in trade. Cities connected to the primate by unpaved roads appear to be more affected by transport costs to secondary cities.

An argument for more roads for Africa?

David McKenzie follows it up with his own tips on the same blog. He makes an observation I’ve heard too often, which is that older development economists eat their young.

For some time I’ve been meaning to write up my own thoughts on how to referee an empirical paper, inspired in large part by a photocopy Betty Sadoulet and Alainn de Janvry handed out in a development economics seminar. While not exactly the same thing, you can see my main suggestions in the last two pages of my causal inference and research design syllabus.

And to save all of us pain, I do have an old advice post on how to be a discussant on a seminar paper. there are many parallels.

Income levels in 1950 were not, it seems, the best guide to why some countries became rich and why some stayed poor. The understudied field of development history has much to teach us. One recent example:

In this paper, we provide aggregate trends in China’s trade performance from the 1840s to the present. Based on historical benchmarks, we argue that China’s recent gains are not exclusively due to the reforms since 1978. Rather, foreign economic activity can be understood by developments that were set in motion in the 19th century.

We turn our focus to Shanghai, currently the world’s largest port. Shanghai began direct trade relations with western nations starting in 1843. By 1853, Shanghai already accounted for more than half of China’s foreign trade.

In tracking the levels and growth rates of the city’s net and gross imports and exports, foreign direct investment, and foreign residents over more than a century, we find that Shanghai’s level of bilateral trade today with the United States, the United Kingdom, or Japan, for example, are by no means high given Shanghai’s 19th century experience.

This paper argues that a regional approach that embeds national trading destinations within an international trading system provides a meaningful approach to understanding the history of China’s trade.

A new working paper by Keller, Li, and Shiue.

I am also fond of this Keller paper on ‘Why the industrial revolution in Western Europe and not China?’

And yes, I have development historian envy.
