This is due not only  to its managerial implications, but also because of  its importance in antitrust policy. The effect of  different geographic definitions on market share and  the systematic differences among them is the major  focus of this research. The analysis is conducted at  the store-level on five geographic market  definitions, in seventeen metropolitan areas, for  two large retail grocery chains. Market share is  measured on two dimensions. One measure is sales per  week for each store. The second measure is square  feet of selling area for each store. The sample  consists of 11,420 supermarkets from the 1997 Trade  Dimensions database.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843370424\"\u003e\u003ch3\u003eThe Market Definition\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843370424","offer_id":39497067397213,"sku":"9783843370424","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/7a5221fa-8ee7-4861-a563-425c043d0b41.jpg?v=1759211429","url":"https:\/\/shop.autorenwelt.de\/products\/the-effect-of-geographic-definition-on-market-share-von-carlos-alfredo-mansilla","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
