Software for the Computation of Markov-Perfect Equilibria in a Dynamic Game of Store Location by Multi-Store Firms

This document is a supplement of the paper "Dynamic Spatial Competition Between Multi-Store Firms" by Aguirregabiria and Vicentini (2007). It describes in detail the library of programs and procedures, in GAUSS language, that is used in that paper. The program computes an equilibrium of a dynamic game of store location and spatial competition by multi-store firms. The equilibrium of the game is a space-time stochastic process for the network of stores of each firm as well as for prices, markups, profits and consumer welfare at every location in the geographic market. We illustrate the use of the program with an example.Dynamic Spatial competition; Store location; Market dynamics; Sunk costs
