I would challenge AI to pose a new math problem that mathematicians would consider a major open question. Not just solve the ones we tell it are important.

Gotta say MIT, this App version does bot come close to Christopher Nolan’s movie or Lattimore's translation
Republican plan to “starve the beast” is, so far, an utter failure, as MAGA Republicans keep finding stupider and stupider things to spend even more of our money on.

The US built the greatest talent magnet ever, attracting the smart, skilled, and striving. They’d come to study, then stay and build things here, or leave with positive impressions and fruitful connections. Helped make the US wealthy and powerful. Then America chose to throw it away. And for what?

Forthcoming in the AER: "Durables and the Marginal Propensity to Spend" by Nathan Zorzi and Martin Beraja.
Durables and the Marginal Propensity to Spend
(Forthcoming Article) - Durables represent a large share of households’ marginal propensity to spend (MPX). We develop a quantitative model of spending that takes durables into account and matches a rich set of empirical regularities simultaneously. Scaling the response of non-durables provides a poor approximation of the MPX on durables when it comes to its distribution in the population, its persistence over time, and its cyclicality. As an application, we study how the MPX varies with the size of stimulus checks and find that it declines more slowly compared to a model of purely non-durable spending.
