I analyze oligopolistic competition among three or more firms located on Hotelling's (1929) Main Srreet and show that in contrast with Hotelling's duopoly, the symmetric locational structure supports a noncooperative equilibrium in prices. © 1987 Wiley JSTOR®, the JSTOR logo, JPASS®, Artstor®, Reveal Digital™ and ITHAKA® are registered trademarks of ITHAKA.

He saw that in the Betrand there is an equilibrium, but if one player undercut his price by a minimal amount he would capture all the profit and thus create instability. 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. organization of industry and applied oligopoly theory A firm that unilaterally moves away from the mid‐point loses André De Palma, Victor Ginsburgh and Jacques-François Thisse, Access everything in the JPASS collection, Download up to 10 article PDFs to save and keep, Download up to 120 article PDFs to save and keep.

The framework and two models 2578 3.2.1. 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.

Wiley has published the works of more than 450 Nobel laureates in all categories: Literature, Economics, Physiology or Medicine, Physics, Chemistry, and Peace. 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. If consumers have a positive probability to purchase from each firm, then centrally agglomerated and/or symmetric dispersed location equilibria may exist in the 3-firm Hotelling problem. 2.
