From Nash Equilibria to Chain Recurrent Sets: An Algorithmic Solution Concept for Game Theory
Entropy, 2018 In 1950, Nash proposed a natural equilibrium solution concept for games hence called Nash equilibrium, and proved that all finite games have at least one.

Strategic (Inconsistent) Disclosures and Sophisticated Investors: Evidence from Hedge Funds
Journal of Accounting Research, EarlyView.ABSTRACT Recent SEC regulations require that qualified hedge fund advisers provide their investors with narrative disclosures of their business and operations. We find that 40% of these disclosures omit or de‐emphasize information regarding advisers' operational and investment risks when compared to other sources of public information. Funds with such “

On the tractability of Nash equilibrium
, 2023 In this paper, we propose a method for solving a PPAD-complete problem [Papadimitriou, 1994]. Given is the payoff matrix $C$ of a symmetric bimatrix game $(C, C^T)$ and our goal is to compute a Nash equilibrium of $(C, C^T)$. In this paper, we devise a nonlinear replicator dynamic (whose right-hand-side can be obtained by solving a pair of convex ...

Integrative Zoology, EarlyView.Sexual cannibalism (SC), where one mating partner consumes the other in the context of mating, is especially prevalent among spiders. However, the evolution of SC in spiders is still not fully understood. We review key hypotheses for SC and explore how female‐initiated SC has driven the evolution of various male counter‐adaptations to mitigate its ...

On a Nonlinear Feedback Strategy Equilibrium of a Dynamic Game [PDF]
This paper reports an intriguing property of a nonlinear feedback Nash strategy equilibrium in a dynamic game with no state variable in the payoff of each player.

The RAND Journal of Economics, EarlyView.ABSTRACT We propose a tractable model of asymmetric platform oligopoly with logit demand in which users from two distinct groups are subject to within‐group and cross‐group network effects and decide which platform to join. We characterize the equilibrium when platforms manage user access by setting participation fees for each user group.

Modeling of Collusion Behavior in the Electrical Market Based on Deep Deterministic Policy Gradient
EnergiesThe evolution of the electricity market has brought the issues of market equilibrium and collusion to the forefront of attention. This paper introduces the Deep Deterministic Policy Gradient (DDPG) algorithm on the IEEE three-bus electrical market model.

Endogenous Technology Spillovers in R&D Collaboration Networks
The RAND Journal of Economics, EarlyView.ABSTRACT We introduce an R&D network formation model where firms choose both R&D efforts and collaboration partners. Neighbors in the network benefit from each other's R&D through technology spillovers, and there exists competition effects reflecting strategic substitutability in R&D.

A Beautiful Blonde: a Nash coordination game [PDF]
In a memorable scene from the …lm ”A Beautiful Mind,” John Nash explains to his friends how to direct their attentions to women in a bar. Game theorists who have seen the …lm point out that the proposed solution is not a Nash equilibrium.
