What’s the latest in development economics research? A round-up of 150+ papers from NEUDC 2015

This page in:
These are figures from just some of the research at NEUDC 2015

Over the weekend, I briefly reviewed about 175 development papers from the 2015 Northeast Universities Development Consortium Conference. That’s not all the papers, but it’s a lot of them. (I tended to leave out pure theory, pure macro, papers the authors didn’t want cited, and a few I just didn’t get to.) If you want to review the papers exhaustively, you can find them here.

It’s an impressive array of research, a lot of exciting work with a wide spectrum of methods.

I’ve grouped papers by category, and I’ve tagged each paper by country and by method, in case you really want to know everything on Uganda or Kyrgyzstan, or you just want to skim the latest randomized controlled trials (RCTs). The categories are Education, then Health (the two biggest groups of papers), then the other categories alphabetically: Agriculture, All In Utero All the Time, Cash Transfers, Conflict, Contracts, Energy, Firms, Governance, Households, Labor, Land, Methods & Measurement, Migration, Randomization, Savings, Credit, & Insurance, Transport, Trade, Tax, and a few others.
