Economists love using linear regression to estimate treatment effects — it turns out that there are perils to this method, but also amazing perks

Come with me in this 🧵 if you want to learn…

In most econ applications, clustering std errors is a problem of design, not sampling. What does that mean? Clustering is needed if treatment assignment is correlated within clusters, not because some clusters were sampled and others were not. 1/8 Jeffrey Wooldridge
