Cross-Validation Equilibrium Ran Spiegler, Stephan Waizmann arxiv.org/abs/2606.12571 [πšŽπšŒπš˜πš—.πšƒπ™·]

Cross-Validation Equilibrium

We study strategic interaction when players delegate belief formation to predictive machine learning (ML). In a static Bayesian game, each player's ML agent predicts a payoff-relevant outcome...

Continuity of equilibria in spaces of Bochner and Gel'fand economies MatΓ­as Fuentes arxiv.org/abs/2606.12492 [πšŽπšŒπš˜πš—.πšƒπ™·]

Continuity of equilibria in spaces of Bochner and Gel'fand economies

We examine the continuity of equilibrium correspondences in infinite-dimensional settings where the commodity spaces are Banach lattices. Economies are modeled as Borel probability measures on a...

Schedules and Prioritization: A Behavioral Foundation for Multi-Armed Bandits and Stopping Problems Jaden Yang Chen, Can Urgun arxiv.org/abs/2606.12044 [πšŽπšŒπš˜πš—.πšƒπ™·]

Schedules and Prioritization: A Behavioral Foundation for...

Bandit models typically begin with arms, states, rewards, and transition rules. This paper instead begins with preferences over stopped local contingent schedules: possible unfoldings of a...

Belief Aggregation under Costly Information Florian Mudekereza arxiv.org/abs/2606.11600 [πšŽπšŒπš˜πš—.πšƒπ™·]

Belief Aggregation under Costly Information

This paper proposes an epistemic foundation for aggregating sets of probabilistic beliefs by retaining only shared beliefs. It develops a model of belief formation under information-acquisition...

Sorting and Global Uniqueness in Two-Good HARA Economies with Many Patience Types Andrea Loi, Stefano Matta arxiv.org/abs/2606.11377 [πšŽπšŒπš˜πš—.πšƒπ™·]

Sorting and Global Uniqueness in Two-Good HARA Economies with Many...

We study global uniqueness of competitive equilibrium in two-good pure-exchange economies with heterogeneous impatience types and a common HARA Bernoulli utility. The paper connects the CRRA...

Revealing information – or not – in a social network of traders Patrick Allmis, Paolo Pin, Fernando Vega Redondo arxiv.org/abs/2606.11053 [πšŽπšŒπš˜πš—.πšƒπ™·]

Revealing information -- or not -- in a social network of traders

We build upon a simple micro-founded model of asset trading proposed by Kyle (1985) to study under what conditions a trader who is privately informed of the future return of the asset may want to...

Iterative Elimination of Borda Losers: Axiomatizations of the...

The Baldwin and Nanson rules are two voting rules proposed to identify the Condorcet winner whenever one exists. Both rules operate as recursive Borda elimination procedures: the Baldwin rule...

Limited belief propagation and contingent thinking Andrew Ellis, Ran Spiegler arxiv.org/abs/2606.10681 [πšŽπšŒπš˜πš—.πšƒπ™·]

Limited belief propagation and contingent thinking

An agent updates her beliefs over a set of variables after observing some of them. We provide a representation of updated beliefs that captures limited propagation of her observation's...

Data-Driven Automation Maryam Farboodi, Andrew Koh, Anchi Xia arxiv.org/abs/2606.10127 [πšŽπšŒπš˜πš—.πšƒπ™·]

Data-Driven Automation

We build a dynamic model of data-driven automation in which data (i) is heterogeneous and task-specific; (ii) accumulates endogenously as a byproduct of economic activity; and (iii) exhibits...

Fair Division of a Heterogeneous Good Between Two Agents: An...

We study the division of a heterogeneous good between two agents into contiguous bundles, each defined by a starting location and a quantity, in a purely ordinal framework that does not rely on...
