The Accuracy Well: Nonmonotone Accuracy Dynamics at Vanishing Initialization
Yaroslav Gusev, Eugene Golikov, Dmitry Yarotsky
We study classification dynamics under small initialization and identify a pronounced non-monotone behavior of accuracy that we call the accuracy well: accuracy rises rapidly early…
In Search of Lost Correlation: Correlated Equilibrium via Marginal Actions
Christopher P. Chambers, Maxime Cugnon de Sévricourt, Christopher Turansick
In this paper, we study which data can be induced by a correlated equilibrium given a known finite simultaneous move game. We assume that an analyst has access to the frequency of…
Identification in Stochastic Choice
Peter Caradonna, Christopher Turansick
We characterize the identified sets of a wide range of stochastic choice models, including random utility, various models of boundedly-rational behavior, and dynamic discrete choic…
Revealed Social Networks
Christopher P. Chambers, Yusufcan Masatlioglu, Christopher Turansick
The linear-in-means model is the standard empirical model of peer effects and asks that an agent's choice or outcome is a combination of their ideal point and the mean outcome of t…
Consumption Dependent Random Utility
Christopher Turansick
We study a dynamic random utility model that allows for consumption dependence. We axiomatically analyze this model and find insights that allow us to distinguish between behavior…
Identifying Restrictions on the Random Utility Model
Peter P. Caradonna, Christopher Turansick
We characterize those ex-ante restrictions on the random utility model which lead to identification. We first identify a simple class of perturbations which transfer mass from a su…
The Limits of Identification in Discrete Choice
Christopher P. Chambers, Christopher Turansick
This paper uncovers tight bounds on the number of preferences permissible in identified random utility models. We show that as the number of alternatives in a discrete choice model…
An Alternative Approach for Nonparametric Analysis of Random Utility Models
Christopher Turansick
We readdress the problem of nonparametric statistical testing of random utility models proposed in Kitamura and Stoye (2018). Although their test is elegant, it is subject to compu…
Intertemporal Aggregation of Choice Data with Consumption Dependent Preferences
Christopher Turansick
We study consumption dependence in the context of random utility and repeated choice. We show that, in the presence of consumption dependence, the random utility model is a misspec…
Correlated Choice
Christopher P. Chambers, Yusufcan Masatlioglu, Christopher Turansick
We study random joint choice rules, allowing for interdependence of choice across agents. These capture random choice by multiple agents, or a single agent across goods or time per…
Identification in the Random Utility Model
Christopher Turansick
The random utility model is known to be unidentified, but there are times when the model admits a unique representation. We offer two characterizations for the existence of a uniqu…
