Abstract:A retailer is endowed with a finite inventory of a nonperishable product. Demand for this product is driven by a pricesensitive Poisson process that depends on an unknown parameter that is a proxy for the market size. The retailer has a prior belief on the value of this parameter that he updates as time and available information (prices and sales) evolve. The retailer's objective is to maximize the discounted long-term average profits of his operation using dynamic pricing policies. We consider two cases. In t… Show more
“…Araman and Caldentey (2009) consider a two-point prior distribution, whereas Farias and van Roy (2010) assume that the prior is a finite mixture of gamma distributions; in both settings, the posterior distributions are in the same parametric family as the prior, which makes the problem tractable. Araman and Caldentey (2009) propose a pricing heuristic based on an asymptotic approximation of the value function of the corresponding intensity control problem.…”
Dynamic pricing and learning is a research topic that has received a considerable amount of attention in recent years, from different scientific communities: operations research and management science, marketing, economics, econometrics, and computer science. We survey these literature streams: we provide a brief introduction to the historical origins of quantitative research on pricing and demand estimation, point to different subfields in the area of dynamic pricing, and provide an in-depth overview of the available literature on dynamic pricing and learning. We discuss relations with methodologically related research areas, and identify several important directions for future research.

“…Farias and van Roy (2010) propose another heuristic, called decay balancing, and show several numerical experiments that suggest that it often performs better than both the heuristic proposed by Araman and Caldentey (2009) and CEP. In addition they prove a performance bound on decay balancing,…”

“…Lobel and Perakis (2011) attempt to bridge the gap between robust and data-driven approaches to dynamic pricing, by considering a setting where the uncertainty set is deduced from data samples. A robust extension of Caldentey (2009) andvan Roy (2010), where finite inventory is sold during an infinite time horizon, is studied by Li et al (2009). Another approach that does not rely on historical demand data is Xiong et al (2010) (see also Li, 2010, Li et al, 2013).…”

“…Note that the definition in Equation (29) has two components which normalize sales data with respect to inter-week as well as intra-week variations. Although these components should be updated every season, we have observed that they have remained in fact quite constant over the years (see Carboni 2009), which shows the formula's robustness and validates its use.…”
Fast-fashion retailers such as Zara offer continuously changing assortments and use minimal in-season promotions. Their clearance pricing problem is thus challenging because it involves comparatively more different articles of unsold inventory with less historical price data points. Until 2007, Zara used a manual and informal decision-making process for determining price markdowns. In collaboration with their pricing team, we designed and implemented since an alternative process relying on a formal forecasting model feeding a price optimization model. As part of a controlled field experiment conducted in all Belgian and Irish stores during the 2008 Fall-Winter season, this new process increased clearance revenues by approximately 6%. Zara is currently using this process worldwide for its markdown decisions during clearance sales.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
