چکیده

We examine contemporaneous perfect ε-equilibria, in which a player’s actions after every history, evaluated at the point of deviation from the equilibrium, must be within ε of a best response. This concept implies, but is stronger than, Radner’s ex ante perfect ε-equilibrium. A strategy profile is a contemporaneous perfect ε-equilibrium of a game if it is a subgame perfect equilibrium in a perturbed game with nearly the same payoffs, with the converse holding for pure equilibria.  2005 Elsevier Inc.

Strategic Complementarity in Multi-stage Games

We provide sufficient conditions in finite-horizon multi-stage games for the value function of each player, associated to extremal Markov perfect equilibria, to display strategic complementarities and for the contemporaneous equilibrium to be increasing in the state variables.

Bargaining over an Endogenous Agenda

We present a model of bargaining in which a committee searches over the policy space, successively amending the default by voting over proposals. Bargaining ends when proposers are unable or unwilling to amend the existing default, which is then implemented. We characterize the policies which can be implemented from any initial default in a pure strategy stationary Markov perfect equilibrium fo...

Climate Policy when the Distant Future Matters: Catastrophic events with hyperbolic discounting

We study climate change policy with hyperbolic discounting under the risk of catastrophic events. Using a binary action model, we compare the set of Markov Perfect Equilibria (MPE) to the optimal policy under (time consistent) commitment. For some initial conditions there are multiple MPE that may involve either excessive or insufficient stabilization efforts relative to the policy under commit...

On essential, (strictly) perfect equilibria

It is known that generic games within certain collections of infinite-action normal-form games have only essential equilibria. We point to a difficulty in showing that essential equilibria in generic games are (strictly) perfect, and we identify collections of games whose generic members have only essential and (strictly) perfect equilibria. © 2014 Elsevier B.V.

Epsilon-equilibria of perturbed games

We prove that for any equilibrium of a continuous (Bayesian) game, and any sequence of perturbations of that game, there exists a corresponding sequence of εequilibria converging to the given equilibrium of the original game. Thus, any equilibrium selection argument that is based on perturbations to a game is not robust to slight perturbations in best reply behavior (or to underlying preference...
