Economic outcomes often depend on the distribution of some maximum value (e.g. the highest valuation, best idea, or lowest cost).
If the average number of options is large, do such outcomes change when some agents have more options than others?

I'm sorry, I'm still talking about the fact that Larry Summers only stopped emailing with Jeffrey Epstein because *he got arrested*. Like there was truly no line in the sand for Summers.

The Federal Reserve is not as independent from the executive branch as we’d like to think. The NY Fed just cancelled this Thursday’s @aeacswep.bsky.social reception at #EEA2025 and withdrew from our summer fellowship program. Both support women and underrepresented groups in economics. #EconSky

Some of the most important lottery anomalies from the behavioral risk literature (e.g., probability weighting and loss aversion) actually have nothing to do with risk.
They also arise in perfectly deterministic settings.

Intimate Partner Violence (IPV) against women is a major public health and inequality concern. It's not clear what causes it or how to reduce it. Gaby Deschamps' JMP considers that IPV is positively correlated with motherhood, and asks if we can understand why. www.gabrieladeschamps.com/research
