Suppose that two owners of refreshment stands, George and Henry, are trying to decide where to locate along a stretch of beach. In this example, Firm x and Firm y will maximize their profit by increasing their consumer pool. {\displaystyle U(d,d_{1})=u-r|d-d_{1}|\,}. There will be … {\displaystyle d\,} Most models take consumers’ locations as given, whereas the model proposed in this paper only assumes given preferences for locations and suppliers. We assume that firms play a location-cum-price game, and that the game is played into two steps. In Hotelling’s Location Model, firms do not exercise variations in product characteristics; firms compete and price their products in only one dimension, geographic location. Firm x will move slightly toward Firm y, in order to gain Firm y’s customers. Here is a really well produced and clear visual explanation of the Hotelling model of spatial location. {\displaystyle u\,} This study estimates a theoretical multi-region industrial location model by adopting real statistics to investigate the intuition of shaping spatial pattern of economic activities in a case of cement industry in Northwest China. endstream

The model in which the network externality is the same for all firms was proposed by Kohlberg (1983), who claims that no equilibrium exists for more than two firms. If both shops sell the same range of goods at the same prices then the locations of the shops are themselves the 'products'. Consumers are now willing to sacrifice pleasure from products for a closer geographic location, and vice versa. for a particular product at distance In this Hotelling model he introduced notions of the equilibrium of location in a duopoly. , and I�]u�^�6Ӳ�zѵK��G�����)w�6�*&�C��Z �t��h�}ѵz��`�v}7S彿&GG���\h4�F��F�s�8�j|��d|�y�h�M4A��;p�ȃ�a$�܊��8o|�7�ZxdF�y��y���PE� �ˡ�9:{n����Y� ?�/�>�a��>�[�8�>����~o!�z��������vDK��i����'��/�J�Q�Y�Λ�F}t�:
