How do you scale up an effective education intervention? Iteratively, that’s how.

David Evans's picture
So you have this motivated, tightly controlled, highly competent non-government organization (NGO). And they implement an innovative educational experiment, using a randomized controlled trial to test it. It really seems to improve student learning. What next? You try to scale it or implement it within government systems, and it doesn’t work nearly as well.

What are Schools Worth? That Depends on the General Equilibrium Effects - Guest post by Gaurav Khanna

Large-scale educational expansions represent substantial investments of public resources and benefit households by increasing education levels, and therefore productivity in the local economy. However, since they impact both individual behavior and labor markets, convincing causal estimates of their overall benefits are hard to generate.

Why did the farmer cross the road? To bridge the productivity divide: Guest Post by Sam Asher

This is the sixth in our series of posts by students on the job market this year.
 The productivity of workers in agriculture is generally much lower than in other sectors of the economy (Gollin, Lagakos and Waugh, 2014). This is particularly true in low-income countries, yet these countries generally have the highest shares of the population living in rural areas and working in agriculture (McMillan et al, 2014). So why don’t workers switch jobs into higher productivity (and better paid) occupations? Development economists as far back as Lewis (1954) and Sen (1966) have studied the labor market imperfections that may keep workers in low productivity agriculture despite higher wages elsewhere.

Pollution, worker efficiency and the role of management: Evidence from India

Markus Goldstein's picture
In a nice, recent paper Achyuta Adhvaryu, Namrata Kala, and Anant Nyshadham take a look at how air pollution hurts productivity and what effect, if any, managers can have in mitigating these effects.   The short answer is yes, pollution hurts worker productivity, and yes, managers with certain qualities do a better job of mitigating these effects as they manage their workers.   That’s the short story, but how they get there is quite fascinating.  

Poverty Reduction: Sorting Through the Hype

After seeing PowerPoint slides of the preliminary findings over the course of more than a year, it’s nice to be able to report that the six-country study that is evaluating the “ultra-poor graduation” approach (originally associated with BRAC) is finally out.

Measured Profit is not Welfare or is it? Intriguing evidence from when microfinance clients gave up microfinance

David McKenzie's picture
I finally got around to reading an intriguing paper by Banerjee, Duflo and Hornbeck that has been on my reading list for a while. This paper is a nice example of making lemonade out of lemons – they had intended to evaluate a health insurance product that a microfinance organization in India made mandatory for its clients in selected villages.

Business training that goes better with friends

Markus Goldstein's picture
The evidence on the effectiveness of business training is, at best, mixed (for an example, see my previous post on David McKenzie and Chris Woodruff's artful review).   As David and Chris point out, part of the problem was methods (esp. sample size).   But even when the methods were good, the results were often lackluster, particularly for women.
