Markov perfect equilibrium is a key notion for analyzing economic problems involving dynamic strategic interaction, and a cornerstone of applied game theory. This lecture describes the concept of Markov perfect equilibrium. Introduction: Importance of strategic interactions: games vs single-agent problems In single-agent problems you search for a solution to a dynamic programming problem, i.e., value function is a xed point of the Bellman equation.

A new Python lecture studying government debt over time has been added to our dynamic programming squared section. De–nition of an Equilibrium There is typically a large number of subgame perfect equilibria in dynamic games, and re–nements are necessary. The lecture covers the econometric methods that have been developed between 80s and 00s to estimate primitive parameters governing imperfect competition among firms, such as production and cost function estimation, demand function estimation, merger simulation, entry and exit analysis, and dynamic decision models.

Markov perfect equilibrium is a key notion for analyzing economic problems involving dynamic strategic interaction, and a cornerstone of applied game theory. 959 0 obj <>stream More precisely, it is measurable with respect to the coarsest partition of histories for which, if all other players use measurable strategies, each player's decision-problem is also measurable. { Investment is strategic: Markov Perfect Equilibrium (MPE). So “bygones” are really “bygones”; i.e., the past history does not matter at all. This note focuses on Markov perfect equilibria (MPEs) in which strategies are conditioned only on the payo⁄-relevant stocks (G and R fR 1;:::;R ng).

Markov perfect equilibrium is a key notion for analyzing economic problems involving dynamic strategic interaction, and a cornerstone of applied game theory. 1 Stochastic Games A (discounted) stochastic game with N players consists of the following elements. Is there enough money in the world for everyone to pay their debts and save enough for retirement without crashing the economy? Without concerns for robustness, the model is identical to the duopoly model from the Markov perfect equilibrium lecture. This lecture describes the concept of Markov perfect equilibrium.

In this lecture we teach Markov perfect equilibrium by example. The cost of this richness is analytical intractability. So âbygonesâ are really âbygonesâ; i.e., the past history does not matter at all. 2.PML estimators for dynamic discrete games: Aguirregabiria and Mira (2007).

Indirectly, this is a discussion on the di erence between political economy and game theory. So MPE says that optimal strategy is function of state, and you only need to figure out what to do in every state, regardless of what was the history of actions that got you to this state. An adequate concept of solution is Nash equilibrium, which prevents unilateral deviations of the players from its recommendation of play. of the Nash equilibrium solution like Seltenâs subgame perfect equilibrium (1965) and perfect equilibrium (1975), Harsanyiâs Bayesian Nash equilibrium (1967-68), or Kreps and Wilsonâs sequential equilibrium (1982) have proved essential to the modern analysis of the indeterminacy of prices under oligopoly. We define Markov strategy and Markov perfect equilibrium (MPE) for games with observable actions. 3.

Markov Perfect assumption became evident when we tried to use the Markov Perfect notions to structure the estimation of parameters, or to compute the ï¬xed points that deï¬ned the equilibria or rest points of the system. Here one player chooses the row and the other chooses a column. This lecture describes the concept of Markov perfect equilibrium. In a dynamic game, basic solution concept is Subgame Perfect Equilibrium, which has strategies as functions of entire history of past actions, so you need to find an optimal action for any possible history.
