Discounted Stochastic Games, the 3M Property and Stationary Markov Perfect Equilibria
We show that all discounted stochastic games DSGs satisfying the usual assumptions have Nash payoff selection correspondences having fixed points. Our...
Layered Networks, Equilibrium Dynamics, and Stable Coalitions
An important aspect of network dynamics that has been missing from our understanding of network dynamics in various applied settings is the influence...
Parameterized State-Contingent Games, 3M Minimal Nash Correspondences, and Connectedness
Under mild assumptions on primitives, we show that all parameterized state-contingent games (PSGs) have upper Caratheodory (uC) Nash (equilibrium)...
A Fixed Point Theorem for Measurable Selection Valued Correspondences Induced by Upper Caratheodory Correspondences
We show that any measurable selection valued correspondence induced by the composition of an m-tuple of real-valued Caratheodory functions with an...
Systemic Risk and the Dynamics of Temporary Financial Networks
This paper has two main objectives: first, to provide a formal definition of endogenous systemic risk that is firmly grounded in equilibrium dynamics...
On K-Class Discounted Stochastic Games
For a discounted stochastic game with an uncountable state space and compact metric action spaces, we show that if the measurable-selection-valued...
Stationary Markov Equilibria for Approximable Discounted Stochastic Games
We identify a new class of uncountable-compact discounted stochastic games for which existence of stationary Markov equilibria can be established and...
Incentive Compatible Networks and the Delegated Networking Principle
We construct a model of a principal-agent game of network formation (over layered networks) with asymmetric information and we consider the following...
Shadow Banks and Systemic Risks
We answer the following question: Does regulating the banking network increase systemic risk in the entire financial network in the presence of...
Parameterized Games, Minimal Nash Correspondences, and Connectedness
Economics and game theory are replete with examples of parameterized games. We show that all minimal Nash payoff USCOs belonging to the Nash...
Stationary Markov Equilibria for K-Class Discounted Stochastic Games
For a discounted stochastic game with an uncountable state space and compact metric action spaces, we show that if the measurable-selection-valued...
A Fixed Point Theorem for Measurable-Selection-Valued Correspondences Arising in Game Theory
We establish a new fixed point result for measurable-selection-valued correspondences with nonconvex and possibly disconnected values arising from the...
Endogenous Correlated Network Dynamics
We model the structure and strategy of social interactions prevailing at any point in time as a directed network and we address the following open...
