As You Sow, So Shall You Reap: The Welfare Impacts of Contract Farming

My article on contract farming titled “As You Sow, So Shall You Reap: The Welfare Impacts of Contract Farming” is finally out in World Development. Here is the abstract:

Contract farming is widely perceived as a means of increasing welfare in developing countries. Because of smallholder self-selection in contract farming, however, it is not clear whether contract farming actually increases grower welfare. In an effort to improve upon existing estimates of the welfare impacts of contract farming, this paper uses the results of a contingent-valuation experiment to control for unobserved heterogeneity among smallholders. Using data across several regions, firms, and crops in Madagascar, results indicate that a 1-percent increase in the likelihood of participating in contract farming is associated with a 0.5-percent increase in household income, among other positive impacts.

If I had to summarize the paper’s contribution informally, I’d say the estimates it presents of the welfare impacts of contract farming have better internal and external validity than those found in previous studies.

Beyond the Market, Part 3: A Paradox Discussed

I wrote two posts on the topic of markets last week. The posts were parts 1 and 2 of a longer post titled “Beyond the Market,” in which I highlighted some interesting facts and paradoxes about markets.

In response to those one of those paradoxes, Saleem writes:

I liked that bit:

‘It is always good, however, to keep in mind that those of us who live in industrialized countries — those of us who live in North America and in Western Europe, especially — are much less in contact with markets than some of us would like to believe.’

Would be cool to see that developed a bit more…”

So what did I mean when I said that we come in contact with the market much less than some people would have you believe? Continue reading →

Beyond the Market, Part 2: Market Paradoxes

Yesterday, I discussed Robert Neuwirth’s book Stealth of Nations: The Global Rise of the Informal Economy, which emphasizes the activities of “illegal street vendors and unlicensed roadside hawkers.”

I concluded by noting how that brought to mind a few conversations I’d recently had with a friend who was observing how, relative to Asia and Africa, few people actually knew how to hustle in America nowadays.

In my Law, Economics, and Organization seminar, I use an old textbook by Milgrom and Roberts. By “old,” I mean that it was the textbook used to teach economics of organization when I was in college. By “old,” I mean that the book is as old as some of my younger students. But I use it because it’s a classic, and because it covers just about everything one needs to know about law and economics and the economics of organization.

Market Paradoxes

In their book, Milgrom and Roberts highlight a first important paradox of markets (I am paraphrasing): Continue reading →

Beyond the Market, Part 1: Hustle and Flow

I am teaching my Law, Economics, and Organization class this semester. The class is for upper-level undergraduates and graduate students, so there is a good variety of backgrounds and interests among the students who enroll in it.

Since the class is a seminar, I spend about half the time teaching, with the other half spent discussing specific papers.

Last Friday, in the context of the module on relational contracts, we discussed two classic papers. The first is Greif’s (1993) paper, in which he discusses the various mechanisms used by 11th-century Jewish merchants around the Mediterranean to sustain long-distance trade. The second is Bernstein’s (1992) investigation of how diamond traders choose to “opt out” of the legal system by developing their own extra-legal institutions.

Hustle and Flow

In the spirit of both articles, I wanted to link to a somewhat dated article in Wired,  a Q&A with Robert Neuwirth, who published a book titled Stealth of Nations: The Global Rise of the Informal Economy last fall. Here is an excerpt: Continue reading →

Our Risk Perceptions Do Not Make Much Sense

So much of what we think and do about risk does not make sense. (…) In Europe, where there are more cell phones than people and sales keep climbing, a survey found that more than 50 percent of Europeans believe the dubious claims that cell phones are a serious threat to health. And then there’s the striking contrast between Europeans’ smoking habits and their aversion to foods containing genetically modified organisms. Surely one of the great riddles to be answered by science is how the same person who doesn’t think twice about lighting a Gauloise will march in the streets demanding a ban on products that have never been proven to have caused so much as a single case of indigestion.

That’s Dan Gardner, in the introduction to his 2009 book Risk: The Science and Politics of Fear. Gardner also has another book out titled Future Babble, on the lack of accountability — not to mention the lack of accuracy — of experts making predictions.

I have the students in my Law, Economics, and Organization seminar read the beginning chapters of Gardner’s book as part of our in-class discussion of risk sharing and incentives, and they usually find Gardner’s book to be thought-provoking. Continue reading →
