The Impact of Hiring Workers from More Productive Firms- what really cool data tells us

A number of developed countries now have linked employer-employee records, although to date I haven’t seen as many papers doing cool things with such data as I would expect. A new paper in the AEJ-Applied (ungated here) by Andrey Stoyanov and Nikolay Zubanov uses Danish data to show what is possible, and help provide some of the most convincing evidence yet that workers carry firm knowledge with them when they move.

The majority of CCT programs with schooling conditions have been found to increase enrollment rates and attendance. Far fewer of the evaluations, however, report results on learning outcomes. Those that do typically find no gains in learning, at least as assessed by test scores.

The first two use school-based testing data and find no impact on test scores.

As we celebrate our first year of the Development Impact blog, we thought it would be a good time to take stock and see what our readers would like in our second year. We’ve already done our survey work and RCT, so now its time for direct, self-selected, feedback from you, the reader.  We want to know:

Evaluate before you leap -- volunteers needed!

It’s been a year since we started the Development Impact blog, and I thought I would use the one year anniversary to focus on one of the classic papers in impact evaluation.    This paper (gated version here, ungated version here) is by Gordon Smith and Jill Pell and appeared in the BMJ back in 2003.
