What works for improving welfare in agriculture: version 0.001

Two years ago, Mike O’Sullivan and I did a post on gender and agriculture.  One of the things we pointed out was that there was a pretty dismal lack of evidence on interventions in agriculture (forget gender).  So I was pretty excited when the recent Campbell Collaboration systematic review on “the effects of training, innovation and new technology on African smallholder farmers’ economic outcomes and food

Customer Information Is Not a Prescription for Counterfeit Drugs: Guest post by Anne Fitzpatrick

This is the twelfth in our series of posts by students on the job market this year

Recent work has suggested that as many as one-third of antimalarial drugs in sub-Saharan Africa are of low-quality, a catch-all term ranging from effective counterfeit medicines to dangerous “fakes” (Nayyar et al., 2012). The persistence of low drug quality may be attributable to asymmetric information (Akerlof, 1970). Patients do not know their need for treatment, or the drug quality at the time of the purchase. In order to maximize profits, providers may then substitute cheaper, lower quality drugs. Bjorkman et al., (2012) find that fake drugs are particularly common in areas with low levels of customer knowledge about malaria transmission, where customers are potentially easier to deceive. However, the only intervention shown to reduce counterfeit drugs is the introduction of a high-quality competitor (Bjorkman et al., 2012; Bennett and Yin, 2014). Might increased customer information about purchases cause suppliers to improve their drug quality?
I address this question in my job market paper. I implement a randomized audit study in Uganda to measure how suppliers adjust price and quality if customers knew what disease the patient had (i.e., “diagnosis”) or knew the particular drug to buy. I contrast the response of drug quality with service quality, which is also low in developing countries (Das and Hammer, 2014). I find that price falls when customers present more information. Counter-intuitively, I find that both service and drug quality fall when the customer presents more information.

Is it just a matter of teaching poor people their rights? An information campaign for India’s NREGA

It is often the case that poor people do not fully access the public services due to them. Information-based interventions have been proposed as a response. The premise is that lack of information is a decisive demand-side factor inhibiting successful participatory action by poor people to get the services to which they are entitled.

Better Nutrition Through Information

In honor of Labor Day here in the US, I want to talk about a recent nutrition paper by Emla Fitzsimons, Bansi Malde, Alice Mesnard and Marcos Vera-Hernandez.   This paper, “Household Responses to Information on Child Nutrition,” is one with a twist – they look not only at nutrition outcomes, but they also try and figure out where these might be coming from – and hence also look at labor supply.
