We show how optimal partisan gerrymandering varies with electoral uncertainty. For realistic parameters, gerrymandering resembles packing-and-cracking for a gerrymanderer with minority support, and uniform districting for one with majority support. buff.ly/JZteJzL

Macro outcomes depend on the distribution of markups across firms/time, making firm-level markup estimates key for macro analysis. Firm data with wide coverage primarily comes from financial statements. Can markups be accurately estimated with such data? buff.ly/tgD0OID

A widely held view is that the Gini coefficient is not decomposable by subgroups. This paper proposes an axiomatic framework that ensures well-behaved within and between-group terms under which the Gini is decomposable with a novel and unique formula. buff.ly/XdnzG6F

Instead of testing for bias from potential misspecification of model restrictions, it's nearly optimal to adapt, averaging restricted and unrestricted estimates using data-driven weights. shinyApp: buff.ly/MmMdwf4 Paper: buff.ly/HsuV7ep

Platform competition in NYC ride-hailing wastes $176M/yr and 21% of driver traffic. A merger would cut traffic by 8% but raise prices, costing consumers $77M/yr. Interoperability rules could reduce traffic by 6% and boost consumer surplus by $63M/yr. buff.ly/MeV4sJz

Many open economies face multiple frictions, including currency premia and constraints on external & domestic debt. This article links the desirability of FX intervention, capital controls and prudential limits to the mix of frictions and how they interact.https://buff.ly/5CAWDdQ

Criminal organizations hinder development. In El Salvador, US deportations seeded gangs whose territorial borders trap residents. Those inside have lower income, education, and well-being than neighbors just 50m away, mainly due to restricted mobility. buff.ly/s9xz4fh

Economic outcomes often depend on the distribution of some maximum value (eg highest valuation, best idea, lowest cost). If the average number of options is large, how do such outcomes change when some agents have more options than others? @sephorahmangin.bsky.social buff.ly/I0CFaj4

From Côte d’Ivoire to the U.S., social obligations to share income are common. Eliana Carranza, Aletheia Donald, Florian Grosset-Touba and Supreet Kaur show their welfare benefits may come at a cost: lower labor supply and productivity. buff.ly/28YCYeT

We show a long-run player who repeatedly observes private signals and takes actions can sometimes establish a reputation even when their strategy is not identified. Our result applies to games of deterrence, delegation, signaling, and Bayesian persuasion. buff.ly/NcrNE6L

Could a highly desirable agent accept a partner that a less desirable agent would reject? When matching requires search in time-changing environments, this paper proves this impossible only where more desirable agents are more patient and less risk-averse. buff.ly/S5uwd3j

Can transparent admissions rules increase access to college? This paper shows two thirds of Texas’ Top Ten Percent Plan’s impact came from information, not mechanical effects, admitting low-income students who outperform those they displace. @adamkapor.bsky.social

We introduce a novel experimental design and econometric model to estimate risk aversion, prudence, and temperance without imposing their interdependence. Our approach unmasks variation in risk attitudes that existing modeling approaches may obscure. buff.ly/4C38RGI

We study how trade policy can reduce global emissions. Unilateral carbon border taxes have limited efficacy at cutting foreign emissions. By contrast, coordinated trade penalties under a climate club prove highly effective. buff.ly/NEE3Uy8

What are the welfare effects of surge pricing? Using Uber data, I develop an empirical model of spatial equilibrium composed of demand, supply, and matching. I find that surge pricing raises total welfare, benefitting riders but hurting drivers. buff.ly/bhTiz9y
