Tools of the Trade: estimating correct standard errors in small sample cluster studies, another take

Jed Friedman's picture

For many years, researchers have recognized the need to correct standard error estimates for observational dependence within clusters. An earlier post contrasted the typical approach to this matter, the cluster robust standard error (CRSE), and various methods to cluster bootstrap the standard error.

Notes from the field: Teaching impact evaluation to policymakers and other non-economists

Markus Goldstein's picture

Back in the tail end of last year, I did a post on using workshops with project teams to build impact evaluation design. My friend anonymous requested copies of the presentations.   Since I am in the midst of doing another one of these workshops here in Ghana, I thought it would be worth posting them now.    

The Mongolian Microfinance Experiment

David McKenzie's picture

I’ve been meaning to read for the last month this new paper by Orazio Attanasio and co-authors, which is the latest in the still small number of studies to carry out a randomized experiment to measure the impact of microfinance. David Roodman was quick to give his thoughts on it in this post, but I thought I’d also summarize it briefly for you and offer my thoughts.

If economists view mental health as one component of human capital, as we typically view physical health, then it’s a natural step to the corollary view that good mental health leads to productivity enhancing behaviors such as increased labor supply, greater effort, enhanced concentration, and so on.

After talking about domestic violence measurement and the need for some kind of model when you think about things like domestic violence with Toan last week, this week I look at a new paper from Jonas Hort and Espen Villanger which both asks the question carefully and definitely makes me think hard about what the ri

How much to referee and how to do it?

I came back from a week off at the start of this year to find 7 referee requests from different journals waiting for me , of which I accepted 5 and turned down 2 – clearly some people are working quickly on that New Year’s resolution to send out their papers. Getting so many requests in the same week got me thinking about both how much I want to referee this year and what I can do to be a better referee.

Schools is Good: A Reply to Lant Pritchett

Lant Pritchett once said to me “Thanks for the comments. As usual they are all very smart and well-informed and I disagree with most.” I feel similarly regarding his very popular piece posted here last week (already one of the top 10 most popular posts in our blog's short history) on how CCTs are forcing children in developing countries into terrible schools. So, here goes a reply…

Dear Lant,
