Decision theory and the "almost implies near" phenomenon
Christopher P Chambers, Federico Echenique
We examine behavioral axioms in decision theory that are satisfied approximately rather than exactly. We demonstrate that in key domains -- decisions under risk, uncertainty, and i…
Manipulation of Belief Aggregation Rules
Christopher P. Chambers, Federico Echenique, Takashi Hayashi
This paper studies manipulation of belief aggregation rules in the setting where the society first collects individual's probabilistic opinions and then solves a public portfolio c…
Revealed preferences for dynamically inconsistent models
Federico Echenique, Gerelt Tserenjigmid
We study the testable implications of models of dynamically inconsistent choices when planned choices are unobservable, and thus only "on path" data is available. First, we discuss…
Recovering utility
Christopher P. Chambers, Federico Echenique, Nicolas S. Lambert
We provide sufficient conditions under which a utility function may be recovered from a finite choice experiment. Identification, as is commonly understood in decision theory, is n…
Binary Mechanisms under Privacy-Preserving Noise
Farzad Pourbabaee, Federico Echenique
We study mechanism design for public-good provision under a noisy privacy-preserving transformation of individual agents' reported preferences. The setting is a standard binary mod…
Rationally Inattentive Statistical Discrimination: Arrow Meets Phelps
Federico Echenique, Anqi Li
When information acquisition is costly but flexible, a principal may rationally acquire information that favors one group over another. The former group faces incentives to invest…
Price & Choose
Federico Echenique, Matías Núñez
We describe a two-stage mechanism that fully implements the set of efficient outcomes in two-agent environments with quasi-linear utilities. The mechanism asks one agent to set pri…
Efficiency in Random Resource Allocation and Social Choice
Federico Echenique, Joseph Root, Fedor Sandomirskiy
We study efficiency in general collective choice problems where agents have ordinal preferences and randomization is allowed. We explore the structure of preference profiles where…
Stable allocations in discrete exchange economies
Federico Echenique, Sumit Goel, SangMok Lee
We study stable allocations in an exchange economy with indivisible goods. The problem is well-known to be challenging, and rich enough to encode fundamentally unstable economies,…
On the meaning of the Critical Cost Efficiency Index
Federico Echenique
This note provides a critical discussion of the \textit{Critical Cost-Efficiency Index} (CCEI) as used to assess deviations from utility-maximizing behavior. I argue that the CCEI…
Empirical Welfare Economics
Christopher P Chambers, Federico Echenique
Welfare economics relies on access to agents' utility functions: we revisit classical questions in welfare economics, assuming access to data on agents' past choices instead of the…
Screening -Hackers: Dissemination Noise as Bait
Federico Echenique, Kevin He
We show that adding noise before publishing data effectively screens -hacked findings: spurious explanations produced by fitting many statistical models (data mining). Noise cre…
Decreasing Impatience
Christopher P. Chambers, Federico Echenique, Alan D. Miller
We characterize decreasing impatience, a common behavioral phenomenon in intertemporal choice. Discount factors that display decreasing impatience are characterized through a conve…
Twofold Multiprior Preferences and Failures of Contingent Reasoning
Federico Echenique, Masaki Miyashita, Yuta Nakamura +2
We propose a model of incomplete \textit{twofold multiprior preferences}, in which an act is ranked above an act only when provides higher utility in a worst-case scena…
Constrained Pseudo-market Equilibrium
Federico Echenique, Antonio Miralles, Jun Zhang
We propose a pseudo-market solution to resource allocation problems subject to constraints. Our treatment of constraints is general: including bihierarchical constraints due to con…
Recovering Preferences from Finite Data
Christopher P. Chambers, Federico Echenique, Nicolas Lambert
We study preferences estimated from finite choice experiments and provide sufficient conditions for convergence to a unique underlying "true" preference. Our conditions are weak, a…
New developments in revealed preference theory: decisions under risk, uncertainty, and intertemporal choice
Federico Echenique
This survey reviews recent developments in revealed preference theory. It discusses the testable implications of theories of choice that are germane to specific economic environmen…
Fairness and efficiency for probabilistic allocations with participation constraints
Federico Echenique, Antonio Miralles, Jun Zhang
We propose a notion of fairness for allocation problems in which different agents may have different reservation utilities, stemming from different outside options, or property rig…
Spherical Preferences
Christopher P. Chambers, Federico Echenique
We introduce and study the property of orthogonal independence, a restricted additivity axiom applying when alternatives are orthogonal. The axiom requires that the preference for…
A characterization of "Phelpsian" statistical discrimination
Christopher P. Chambers, Federico Echenique
We establish that statistical discrimination is possible if and only if it is impossible to uniquely identify the signal structure observed by an employer from a realized empirical…
Preference Identification
Christopher P. Chambers, Federico Echenique, Nicolas S. Lambert
An experimenter seeks to learn a subject's preference relation. The experimenter produces pairs of alternatives. For each pair, the subject is asked to choose. We argue that, in ge…
