“…This paper is devoted to the study of spatial demand in the case where consumers are allowed to practice multipurpose shopping. The determinant role of that kind of shopping behavior in the setting up of demand as well as in the location of shopping opportunities was recognized by Christaller (1966, p. 50) and Losch (1954, p. 76) and is confirmed by empirically supported studies (Wheeler 1972;Hensher 1976;Bentley, Bruce, and Jones 1977;Hanson 1980aHanson , 1980b. However, the first attempts to integrate the multipurpose shopping practice in spatial demand theory are quite recent (Papageorgiou and Brummell975;Lentnek, Hanvitz, and Narula 1981;Eaton and Lipsey 1982;Stahl 1982;Narula, Harwitz, and Lentnek 1983;Mulligan 1983Mulligan , 1984.…”
