Measuring the incentive to collude: the vitamin cartels, 1990–99

M Igami, T Sugaya - The Review of Economic Studies, 2022 - academic.oup.com
Do mergers help or hinder collusion? This article studies the stability of the vitamin cartels in
the 1990s and presents a repeated-games approach to quantify “coordinated effects” of a …

Stochastic Nash equilibrium problems: Models, analysis, and algorithms

J Lei, UV Shanbhag - IEEE Control Systems Magazine, 2022 - ieeexplore.ieee.org
Decision making under uncertainty has been studied extensively over the last 70 years, if
not earlier. In the field of optimization, models for two-stage, stochastic, linear programming …

The folk theorem in repeated games with anonymous random matching

J Deb, T Sugaya, A Wolitzky - Econometrica, 2020 - Wiley Online Library
We prove the folk theorem for discounted repeated games with anonymous random
matching. We allow non‐uniform matching, include asymmetric payoffs, and place no …

Asynchronous schemes for stochastic and misspecified potential games and nonconvex optimization

J Lei, UV Shanbhag - Operations Research, 2020 - pubsonline.informs.org
The distributed computation of equilibria and optima has seen growing interest in a broad
collection of networked problems. We consider the computation of Nash equilibria of convex …

Cheap talk, monitoring and collusion

D Spector - Review of Industrial Organization, 2019 - Springer
Many collusive agreements involve the exchange of self-reported sales data between
competitors, which use them to monitor compliance with a target market share allocation …

Combining local and global evolutionary trajectories of brain–behaviour relationships through game theory

S Di Plinio, SJH Ebisch - European Journal of Neuroscience, 2020 - Wiley Online Library
The study of the evolution of brain–behaviour relationships concerns understanding the
causes and repercussions of cross‐and within‐species variability. Understanding such …

Brownian signals: information quality, quantity and timing in repeated games

A Osório - Computational Economics, 2018 - Springer
This paper examines different Brownian information structures over varying time intervals.
We focus on the non-limit case, and on the trade-offs between information quality and …

Reasoning About 'When'Instead of 'What': Collusive Equilibria with Stochastic Timing in Repeated Oligopoly

J Grana, J Bono, D Wolpert - The BE Journal of Theoretical …, 2019 - degruyter.com
We analyze a continuous time game of Bertrand competition with private monitoring that
includes asynchronous signals and asynchronous actions. Unlike existing models where …

Approachability with delayed information

D Lagziel, E Lehrer - Journal of Economic Theory, 2015 - Elsevier
We consider a sequential decision problem where the decision maker is informed of the
actual payoff with delay. We introduce a new condition, which generalizes the condition …

Observation delays in teams and effort cycles

S Gordon, C Marlats, L Ménager - Games and Economic Behavior, 2021 - Elsevier
This paper studies the dynamics of effort provision in teams when there are exogenous
observation delays between partners. Agents are engaged in a common project whose …
