Blattman Responds: "Don't Lose Hope"

It speaks really well of him that he would respond to my rant attacking his field.

We're probably not that far apart on the basic issue. I liked the syllabus he put together for his class. And I can understand that a field course is necessarily going to have to teach method, but I'll maintain it should go well beyond just method (and I suspect he wouldn't disagree).

Perhaps I'm just bitter I was never assigned Crosby or Kamarck.

In any case, here's the bulk of his post:
First, something that becomes clear only in retrospect: a graduate class in any field of economics is not attempting to teach you about the big ideas in that field; it’s attempting to teach you method. Your professors are showing by example how to write a tight, well-theorized, well-identified research paper. You have the rest of your life to learn about why some countries are poor (the logic goes) but you will never outside of that class teach yourself how to build a structural model.

Second, a lot of economics research aims to answer narrow questions very well–especially the kind of research that gets you a good job or tenure. Some of this work is mathematical masturbation. Some is a rehashing of puzzles that economists care about only because they are puzzles (and it’s a chance to be clever). But a lot of the research is very good and very important.

To see an example, take a look at Esther Duflo and Abhijit Banerjee’s Growth Theory Through the Lens of Development Economics. They aggregate oodles of mainstream development research into a set of answers (and unanswered questions) about the larger process of development. I think it’s marvelous. And there are many more examples (or I’d have little to write on this blog). Indeed, most of the mainstream development people, in their main work or behind the scenes, contribute to development thought that really matters.

Finally, those seemingly pointless papers that rehash an irrelevant question serve a higher purpose: they advance the method. I could care less about the 100th paper on the ‘returns to education’. Who cares if it is 0.12 or 0.14? But the debate that raged to identify one silly parameter did more to advance our understanding of causal identification in statistics that almost any other question in social science. And the literature is better for it.

Do I wish that junior faculty could pursue big and fuzzy questions in development without committing tenure suicide? Yes. Is the profession distorted towards a narrow set of questions that be answered with a specialized set of tools? To some degree. But do I think that the demand for excruciating rigor in theory and statistics has changed the world? Absolutely.

I finish with the advice from the brilliant, senior, fuzzy development economist who stopped me from leaving the PhD: “Yeah, there’s a lot of bulls**t, but it’s good for you, and it will get better, and soon you’ll get to do what you really want to do. So suck it up and stay.”

I did, and with no regrets. Don’t lose hope.


  1. I came here cos someone told me it was a site for lonely men who might be looking for some action. Instead all I find is endless discussion about bloody economics. Veblen, you're responsible and I know where you live.

  2. eff off Shore! you wanks r going down next summer
