🚨 Excited to share a new paper in @AnnalsofIM 🚨
Our goal: LaLonde (1986) but in context of assessing heath plans...

We studied a unique context in which 2/3 of Medicaid enrollees were randomized to 1 of 5 plans ("RCT-like" evid.) and 1/3 selected a plan ("observational" evid.).
Using risk adjustment methods on observational sample, we generally could not recover the RCT-like estimates. (2/5)

New working paper: Mark Egan, Hanbin Yang, and I use a comprehensive dataset of 401(k) retirement plans from 2009-2019 to examine heterogeneity in investment behavior. For example, 44 percent of assets are allocated to U.S. equity funds, but this varies widely across plans... 1/5

In the US, more educated immigrants raise local vote share for Democrats, less educated immigrants reduce it.
Halving immigration overall would have hurt Democrats in 2016, since former effect exceeds latter

New research shows that short-term high-interest digital credit in Malawi had no significant impact on well-being. Notably, a financial literacy intervention intending to increase awareness about risks and costs actually increased (!) demand and repayment, increasing overall risk

How can we map predictions of such notional unified consumption models to the real world? In particular predictions about marginal propensities to consume (MPCs)?
This is the question we tackle in a short paper with David Laibson and Peter Maxted

Just got to discuss a compelling new paper on the downstream effects of increasing abortion access from @ninarbrooks and @ZoharTom at #ASSA2022. An (event study) picture is probably worth 1,000 (or 280) words:

Great thread about how the credibility revolution widened economics’ scope by introducing tools that didn’t depend on economic theory. Sometimes I narrowly feel that requiring clean causality limits the set of questions but often forget just how many domains economics now covers!
scott cunningham @causalinf
That Card speech on design vs model based approach to causal inference in the history of empirical micro is all I can think about this last week. His discussion of the role of the "model" in these three broad approaches -- I can't get it out of my head. 1/
