So, what does all this mean for inequality? 85% of rise in the 1% share has gone to migrants. 2/3 to 1/2 of rise in top 0.1 and smaller shares. (UK is "importing" ineq) ⚠️this is NOT a claim that migrants *cause* inequality. just laying out where the money is going right now⚠️

Aggregate investment responds sluggishly to shocks or changes in policy. E.g., investment spending peaks with 8-quarter delay after Fed policy rate cut. Puzzling b/c returns higher at time of rate change. Why? My paper Investment under Rational Inattention offers an explanation

Drenik, @simon_jaeger, Plotkin and @Schoefer_B use Argentinian data to study the degree to which temp agency workers receive firm-specific pay premia. They find they receive on average *half* of the premia of full time/regular workers. [1/3]

New version of "Paying Outsourced Labor:" Temp-agency workers' inherit ~50% of the pay premia (AKM firm FEs) of regular workers. That is, >0%, yet <100%.

TL;DR: Control of the VC-backed startup board shifts from entrepreneur, to shared between VC and entrepreneur, to VC. VC control is sticky. The *independent director* plays a central role in this transition and acts as a mediator between the entrepreneur and VC. 2/13

Suppose you are a robust decision maker. You care about the highest and lowest estimate of an effect, across different model specifications. The researcher has incentives to find an upper bound. The replicator, a lower bound. The real effect should be in between!

Null hacking [v]: the process by which replicators seek to get a "failure to replicate" because they believe these types of replications are more likely to be published. How do we address incentives to null hack in observational work? 👇👇👇 https://t.co/R4LbSAzCFE https://t.co/LRkrPY9kx2

We are glad that our paper on Frontier Culture is receiving attention outside economics, but based on the comments here it is clear we need to make some clarifications. Thread [1/12]

The American Frontier shaped a culture of rugged individualism. It attracted individualistic types and made settlers more individualistic over time; its effects persist today as more exposed counties show greater opposition to government https://t.co/jl9651Njs9 https://t.co/oYAk8YXVnT

I recently put together a list of organizations where people interested in (non-academic) jobs in behavioral economics/applied microeconomics should look. I figured it would be worth sharing more broadly! (1/n)

Does anyone have an intuitive explainer for matrix completion? I read the Athey et al paper but could use an MC for Dummies companion piece.
