Issues of data collection and measurement | Impact Evaluations

­World Bank Blog Post

 About five years ago, soon after we started this blog, I wrote a blog post titled “Economists have experiments figured out. What’s next? (Hint: It’s Measurement)” Soon after the post, I had folks from IPA email me saying we should experiment with some important measurement issues, making use of IPA’s network of studies around the world. At the time, we made some effort to organize an initial workshop to discuss what we know and what we need to know, but things fizzled out. Fast forward to this Spring when IPA did send out an invitation for a workshop on measurement issues (attendees found out that this is actually the second of such workshops, the first of which took place in 1999, which was when Dean Karlan met Chris Udry for the first time: the two organized last week’s workshop at Yale).
