✨Bell postdoctoral fellowship has allowed me to challenge my assumptions and to see beyond my understandings of society. If you're looking to grow by standing on the shoulders of giants, this might be the position for you!

Feel free to reach out if you'd like to hear more about the experience :)

The evidence keeps accumulating that Brexit was an astonishing self-inflicted economic policy disaster. The fact that it is a slow-moving one bodes ill for those who think that populist economic mismanagement will translate into voters punishing populists. www.nber.org/system/files...

A good peer reviewer - who engages thoughtfully and constructively, teaches, notes what's good about a paper and what can be improved - is such a positive force. As a mentor (and as an editor and an author), I send out deep thanks to everyone who works hard to write kind and useful reviews.

I think this question was probably the starting point of Dube, Lester, and Reich's (2010) “local estimators comparing all contiguous counties” approach...! At the very least, spatial heterogeneity would be less concerning than simply including state FE.

Conceptual Framework of Transfer Learning Method

Conceptual Framework of Transfer Learning Method

We use transfer learning, a machine learning approach that addresses the deviation-variance tradeoff.

It combines large source data with small target data to create a dementia estimation algorithm.

Invited Commentary: Where Do the Causal DAGs Come From?

Abstract
How do we construct our causal DAGs, e.g. for life course modelling and analysis? In this commentary I review how the data-driven construction of causal DAGs (causal discovery) has evolved, what promises it holds and what limitations or caveats must be considered. In conclusion I find that expert- or theory-driven model building might benefit from some more checking against the data and causal discovery could bring new ideas into old theories.

Already suspected that I would like this after her talk yesterday, but I really do dig her writing -- it's very crisp and accessible.
