Please RT! If this thread is helpful, I'll write a Part 2 on filing FOIA lawsuits.

Need time to dig into this, but this decomposition could become a standard part of any paper using IV:

"IV-OLS coefficient gap is explained by differences in the weights on the covariates, the weights on the treatment levels, and the identified marginal effects."

Mobile apps and websites are now the leading way customers interact with their banks

…which is a business that traditionally relied on intangible info collection through local branches…

How is this changing the nature of banking?

My job market advice for candidates. Stop reading job market advice on X.

Seriously, some of this advice, while well-intended, is just silly. You have accomplished a lot already, so just continue to use your very good judgment that brought you this far.

Good luck. Enjoy it!

@danascoot There is nothing useless. It’s just part of the learning process so that your next variation is better. But with a deadline you probably want to hedge the risk by having a second project.
