Where do firms locate: the home market effect 2576 3.1. 3-FIRMS LOCATION PROBLEM A. SHAKED Location problems of firms on a closed interval were introduced by Hotelling [3] and later investigated by Eaton & Lipsey [2]. Hotelling's rule defines the net price path as a function of time while maximizing economic rent in the time of fully extracting a non-renewable natural resource.The maximum rent is also known as Hotelling rent or scarcity rent and is the maximum rent that could be obtained while emptying the stock resource. Firm 1 is located at distance 1/3 from the left end and firm 2 is located at distance 1/3 from the right end. Where did we stand in 1990? 2.2.3. Cyber crime issues 7.

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. This paper extends the standard Hotelling model with quadratic transport costs to the multi-...rm case. So, for example, for n = 2, two players occupy the position 1/2.
