Abstract:
Consider observations from a single equilibrium of a Hotelling–type model with exogenous locations in which each player, a firm, has a finite number of actions (discrete choice) and is subject to interactions that are local–for example, the two surrounding neighbors in a “linear” Hotelling model. Asymptotics in this setting is studied by assuming that all the players are located in a single market and that the number of them grows. All observations are potentially dependent to each other because they are interpreted as arising from a single equilibrium of settings where players interact directly or indirectly. Simple assumptions about the structure are made that ensure that the game with a fixed number of players has a unique equilibrium and the equilibrium has a stability property. The formulation of this stability property is new and is the basis for consistency. I introduce an estimation procedure called (sieve) maximum approximated likelihood. This estimator has the same asymptotic properties as the corresponding maximum likelihood estimator, but is easier to compute.
