- Is it better to be a big fish in a small pond/should you send your kid to a better school? Kellogg insight on work by Roland Fryer and co-authors on how peer effects play out with relative rank changes.
- A new paper puts together intra-cluster correlation coefficients for designing cluster education experiments in Africa. (h/t Dave Evans)
This was a question posed by one of our readers in a comment on an earlier post I did on how to calculate the intra-class correlation in Stata.
In clustered randomized experiments, random assignment occurs at the group level, with multiple units observed within each group. For example, education interventions might be assigned at the school level, with outcomes measured at the student level, or microfinance interventions might be assigned at the savings group level, with outcomes measured for individual clients.
