Excited to FINALLY release toughest+most rewarding paper I've worked on...

….we attack a 150 year old Walras question that's gone unanswered, not for lack of trying (Hicks, Samuelson, Arrow; our chances?😱)...

Q: Is the market equilibrium stable or unstable?¯\_(ツ)_/¯

Why do richer economies have more very large firms? This paper shows that the upper tail of the firm size distribution thickens as economies grow. A model of idea search explains why, showing how growth itself can produce rising concentration.

Why do standard statistical methods struggle with spatial data?
A new @EconomicsUCD working paper introduces a simple but powerful way to improve spatial inference by “pre-whitening” dependence in the data — helping researchers draw more reliable conclusions.

I've updated my undergrad and grad 'metrics course slides from this spring -- including new material, (many) fixed typos, and more!

Check 'em out on my website (link below), and feel free to email for the source materials if you'd like to use some of it for your own teaching

[Econometrica @ecmaEditors]

Local projections are surprisingly robust to misspecification. By contrast, VAR confidence intervals with short-to-moderate lag length can severely undercover for misspecification that is small, difficult to detect, and cannot be ruled out a priori.

For researchers interested in U.S. banking and finance, we are sharing a new data resource!

It contains information on bank balance sheets, bank runs, and bank failures from the 19th century to the present:

Next slides up in my course on the political economy of early America:

“The Atlantic World.”

https://t.co/9H6Ka6d5EO

Three big questions I want to tackle:

Why did Europeans reach the Americas in 1492 rather than 1192 or 1792?

Why did rival European empires build such different institutions in the same hemisphere?

How did the Atlantic system shape the conditions under which British North America emerged?

I spend a lot of time on Britain because the Stuart Century is absolutely central to understanding 1776. That so few Americans grasp this today is unfortunate. You really need to see why James I (hardly a household name for most people in the U.S.) shocked the British Isles so profoundly before you can make sense of what happened in Philadelphia on July 4, 1776.

The previous slide decks are:
