RFID Bleg + Summer Opportunity if you know how to do this stuff

David McKenzie's picture

I am in the early stages of exploring how to use RFID tags to improve measurement of turnover in small businesses. Does anyone know of cases where RFID tags have been used to track aid flows, or in development projects to track mass quantities of goods? I know technology is rapidly evolving and price dropping here, but would be good to know of recent experiences on this.

Climate change and conflict

Markus Goldstein's picture

I was at the Centre for the Study of African Economies conference this week, and Ted Miguel gave a fascinating keynote lecture.   The talk is based on a paper with coauthors Marshall Burke and Solomon Hsiang where they look at the effects of climate change on conflict.    And it was fascinating because they pull together a range of different evidence to build the case that if we care about conflict we o

Evaluating after the barn-door has been left open: Evaluating Heifer’s Give-a-Goat or Give-a-Cow Programs

The gift of a dairy goat represents a lasting, meaningful way for you to help a little boy or girl on the other side of the world (US$120); or how about a flock of ducks (US$20); or go all out and donate a water buffalo ($250). People need "a cow, not a cup"—cows that could produce milk so families would not have to depend on temporary aid.

International animal donation programs of the type mentioned here are one of the most well-known types of charitable requests, and are used by a number of major charities worldwide. The best known exponent of this program is Heifer International, from which the examples above are taken.  The purported goals of such programs are to improve the nutritional outcomes of participating households and provide a pathway out of poverty.

Tools of the trade: when to use those sample weights

Jed Friedman's picture

In numerous discussions with colleagues I am struck by the varied views and confusion around whether to use sample weights in regression analysis (a confusion that I share at times). A recent working paper by Gary Solon, Steven Haider, and Jeffrey Wooldridge aims at the heart of this topic. It is short and comprehensive, and I recommend it to all practitioners confronted by this question.

Introducing the Africa Gender Innovation Lab

Today I wanted to take the opportunity to talk about a new initiative that the Africa Region and the Research Group at the World Bank are launching today.   The idea here is that we don't know enough about how to effectively address the underlying causes of gender inequality. Let me start by explaining what I mean by underlying causes.    Take the case of female farmers.    There is a lot of literature out there which shows that women have lower agricultural yields than men.   And some of it shows that this is because women have lo
