RT info:eu-repo/semantics/article T1 Optimal retail price promotions A1 Beltov, Tor A1 Jorgensen, Steffen A1 Zaccour, Georges A2 Ediciones Universidad de Valladolid K1 Economía política K1 Economía de empresa AB The paper proposes a dynamic optimization model for a retailer's price promotions of two brands in a product category. There is no general concensus in empirical marketing literature on what are the impacts of a promotion on intertemporal consumer behavior. This paper will focus on three effects: (1) The immediate, and positive, impact of a price deal on the sales of a promoted brand; (2) Brand substitution, where some consumers switch from a nonpromoted brand to a lower priced promoted brand; and (3) Consumers stockpile a promoted brand during a deal period, which affects postpromotional demand. The paper characterizes the magnitude of discounts as well as the timing and durations of promotions. Optimal policies for a myopic and a forward looking retailer are identified. We also provide comparative statics that identify the dependence of discounts and durations upon key model parameters SN 0213-7569 YR 2006 FD 2006 LK http://uvadoc.uva.es/handle/10324/19790 UL http://uvadoc.uva.es/handle/10324/19790 LA spa NO Anales de estudios económicos y empresariales, 2006, N.16, pags.9-36 DS UVaDOC RD 05-may-2024
