Chris Blattman on RCTs in Development Economics

Although I had seen the Glennerster and Kremer article in the Boston Review last week, I had saved it for later, as I was planning on reading it carefully so as to possibly assign it as an introductory reading in the development seminar I teach in the fall.

In a recent blog post, Chris Blattman has excellent thoughts on the article and on randomized controlled trials (RCTs) in general:

Madonna’s Malawi Charity Fails, Blames Former Trainer’s Husband

An article in The New York Times this morning discusses how Raising Malawi, the charitable foundation Madonna set up with the goal of building a school for girls in Malawi, is a shambles.

This comes after the foundation’s executive director — Madonna’s former trainer’s husband — left last fall after being criticized for his management style.

Madonna set up the Raising Malawi foundation with the goal of building a $15 million school for 400 girls:

How to Prevent Another Food Crisis?

A student in my micro course brought to my attention this op-ed in Foreign Policy by Bruno Le Maire, France’s Minister of Food, Agriculture and Fishing, about what the G-20 can do to prevent a food crisis:

“As France assumes the presidency of the G-20 this year, trouble is brewing in the commodities markets. During our country’s leadership over the next nine months, we are determined to head off crisis before it strikes the world’s poor, as high food and oil prices did just three years ago.”

I would like to note a few things. First and foremost, make no mistake: what we are currently experience is a food crisis, as food prices have never been this high since the Food and Agriculture Organization of the United Nations began recording food prices in 1990. When will politicians and policy makers finally have the courage to call it that?

Second, throughout his op-ed, Le Maire uses and abuses the notion of food price volatility:

“Whether the trend is upward or downward, the increasing volatility of commodity prices is intolerable for producers everywhere in the world because they don’t have any visibility regarding their investments. When the trend is upward, volatility is intolerable for the consumers who have to pay more for their food.”

Note that he discusses both trend — what I refer to as the food price level — and volatility. Those are two different concepts, as they represent the mean and the variance of the food price distribution.

Although he is right when he discusses how food price volatility hurts producers, Le Maire confuses things when he simultaneously talks of an upward trend and of volatility for consumers. Yes, rising food prices hurt consumers. But my own research findings indicates that volatility is actually slightly beneficial to consumers, as I have discussed before.

For what it’s worth, Le Maire proposes two policy solutions. The first is an investment in global agriculture, and the second — which befits a French cabinet minister — is an expansion of market regulation.
