Standard stochastic choice models used to estimate risk aversion can lead to risk-aversion reversals, where a more risk-averse individual chooses a riskier lottery more frequently than a less risk-averse individual. We study when reversals…
A representative democracy is immune to gerrymandering if it satisfies Chambers' (2008) representative consistency. We examine preference aggregation and show that representative consistency is mutually inconsistent with three other…
On a large French ridesharing platform, new minority drivers earn 11.6% less revenue than otherwise similar nonminority drivers; the gap nearly vanishes as they accumulate reviews. Reviews drive the convergence: when a railway strike…
We study joint decision-making when agents agree on all primitives other than signal likelihoods. We propose a decision-theoretic measure of interpretive disagreement: a pair of subjective models is more agreeable than another if, uniformly…
Global games theory provides a tractable framework for analyzing coordination problems with multiple equilibria, with regime overthrow serving as a canonical application. A large empirical literature on coups d'\'etat examines the…
We prove that every mean-zero probability law on the real line is the law of X-Y for some identically distributed real-valued random variables X and Y.
This paper presents a computational approach to find an approximately minimax estimator for the classical Bounded Normal Mean problem. The suggested procedure is the Bayes estimator corresponding to an approximately least-favorable…
We characterize the asymptotic behavior of conventional variance estimators in linear regression with high-dimensional fixed effects under a drift in which both the proportional fixed-effect dimension $\rho_n = d_{K_n}/n \to \rho \in [0,1)$…
This paper develops a novel estimates of annual private sector agricultural R&D at the level of US states for the period 1976-2014. For each of five different agricultural subsectors, I allocate estimates of national private sector R&D…
This paper studies the performance of data-driven decisions from a geometric perspective. A policymaker learns from an innovated donor population to decide whether to innovate groups in a distinct target population, and must compensate for…
Decision-makers usually receive information through narratives that combine diagnostic evidence with nondiagnostic details. In a laboratory experiment, we study how such nondiagnostic clues affect belief updating. Participants repeatedly…
Agentic AI is shifting online shopping from search toward delegated purchasing, where autonomous buying agents monitor markets and decide when to buy on a consumer's behalf. We study the design of such strategic buying agents, which must…
Social scientists often ask about the effect of increasing one's duration of exposure to a social context on one's outcomes, i.e. the overlap effect. Past studies adopted a unidimensional treatment effect framework to estimate the effect of…
This article reassesses the meta-analytic evidence on the effect of International Monetary Fund programs on economic growth. The point of departure is the influential meta-analysis by Balima and Sokolova, which assembles 994 estimates from…
The conditional likelihood ratio (CLR) test is a valuable tool for inference under weak identification, with appealing theoretical properties in both linear and non-linear settings. Its implementation nevertheless requires minimizing a…
As firms increasingly adopt AI-powered pricing algorithms, a key and urgent policy concern is how to regulate the potential algorithmic collusion. This paper approaches the regulatory question through the lens of information design and…
The rich have emitted the bulk of greenhouse gases. The poor suffer the bulk of the impacts. Climate change is a transfer from poor to rich. Climate policy is a transfer from rich to poor. Why, Schelling asked, do people in the Global North…
I study the problem of selecting a jury from a qualified panel. Every jurisdiction in the United States (with the exception of Arizona) allows litigants to exercise peremptory strikes on the panel to eliminate potential jurors, with the…
We provide an analytical framework that allows for distilling the full explanatory and welfare-relevant content of influential yet computationally hard models of bounded-rational general choice. We do so by introducing constraint…
We study unanimous and strategy-proof probabilistic social choice correspondences (PSCCs), where the selected set of alternatives is interpreted as an interim outcome, and agents evaluate sets using conditional expected utility. We analyze…
