J. Reg. Starting with the works of Hotelling (1929) and Downs (1957), models of spatial competition have been widely studied in the economics and voting literature. Hotelling's law is an observation in economics that in many markets it is rational for producers to make their products as similar as possible. My model is a special case of the price-setting stage of the Hotelling model but with a non-uniform distribution of consumers. A problem with the Hotelling model when applied to commerce is that the results are very sensitive to the cost assumption. This is one of the major problems in hotel industry. Buyers are uniformly distributed in a line of length one, where L is the left end and R the right end. The two firms choose to locate at the mid‐point of the line. 3.2. (This is the median voter theorem.) 1. There must be some cost to traveling because customers prefer the closest vendor.

This is done separately for the short and long run. descriptive rather than a formal test due to the unavailability of firm cost data. Public violence 3.

The Journal of Industrial Economics covers all areas of Hotelling's theory addresses a fundamental decision for an owner of a non-renewable resource: keep the resource in the ground and hope for a better price the next year, or extract and sell it … In this model he introduced the notions of locational equilibrium in a duopoly in which two firms have to choose their location considering consumers’ distribution and transportation costs. firms simultaneously choose a location, or Firm 1 chooses a location after Firm 2, the problem becomes trivial: Firm 1 may simply locate at the same spot as Firm 2 and Firm 2 earns zero profit. This paper reports the results of an experimental study of the three agent location problem.
