Abstract
In this paper we provide new insights on the method for computing Markov perfect Nash equilibria presented for the first time in [12]. This method does not use the Hamilton—Jacobi—Bellman equations, but characterizes Markov perfect equilibria by means of a system of quasilinear partial differential equations. A quasilinear system is much more amenable than a fully non-linear system of partial differential equations as the Hamilton—Jacobi—Bellman system usually is. This fact allows us to establish results on existence and uniqueness of solutions and also to derive its analytical expressions in some cases. Otherwise, this approach simplifies a qualitative analysis, making possible the application of well—known numerical routines to find an approximate Nash equilibrium. The main features of the method are shown in the analysis of some competitive resource games.KeywordsNash EquilibriumMarginal UtilityDifferential GameResource StockQuasilinear SystemThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
