I am a dual citizen of two countries, both of which legalized safe abortions when I was little or young, meaning that I grew up taking a woman’s right to a safe abortion as granted. Usually, when I hear family planning policy, I think of men and women planning the number, the timing, and the spacing of their children with the aid of modern contraceptives.

The previous post in this blog discussed the positive dynamic effects of conditional cash transfer (CCT) programs in Mexico and Nicaragua – in particular on asset accumulation and the incidence of entrepreneurship by the rural poor.
While some of us get to conduct individually randomized trials, I’d say that cluster randomized trials are pretty much the norm in field experiments in economics. Add to that the increase in the level of ambition we recently acquired to have interventions with multiple treatment arms (rather than one treatment and one control group) and mix it with a pinch of logistical and budgetary constraints, we have a non-negligible number of trials with small numbers of clusters (schools, clinics, villages, etc.).
I made a temporary move recently, which left me without a dog walker for our two beloved (and very active) dogs, without a delivery option for good takeout food, and a need to build a fire in a wood stove every day. I had never spent this much time during weekdays walking the dogs, cooking, and carrying wood from the garage to build and maintain a fire throughout the day. Without the takeout food and all the hiking, I am healthier and somewhat less stressed, but the shift in time use takes some adjusting to…
After last week’s review of Mark Rosenzweig’s review of Poor Economics, I got asked, via email and comments, what I thought about Martin Ravallion’s review in the same issue of the Journal of Economic Literature.
Suppose that you’re told that a program reduced the rate of dropping out of school among 15 year-olds by 17% and this reduction was statistically significant. You are also told that the same figure among 12 year-olds is 38%. You would likely take note. Suppose now you’re told that these are the effects of a conditional cash transfer program, where the dropout rate among the control group is 37.7% and 16.8%, respectively for ages 15 and 12, thus the absolute effect sizes are 6.4 percentage points in each case.
Given that we are in a somewhat reflective mood this week due to the fact that it has been a year since we started this blog, I figured I’d highlight some of the comments that we received so far here and share some of my thoughts on these comments and related issues that have been on my mind recently as potential posts…
