Consumer Behavior

Different theories, areas of substantive interest, and methods are needed to prevent consumer behavior from becoming increasingly isolated and of marginal relevance in market research. More progress will be made by focusing on relatively underresearched areas, such as: 1. focus on time, 2. the adaptive consumer, and 3. relevant dependent variables. Avenues for substantive focus include: 1. important decisions, 2. not just price and advertising, and 3. the impact of major events. Issues that arise with respect to the methods used to study consumer behavior include: 1.

This paper studies an incomplete contracting model to compare the effectiveness of alternative transfer pricing mechanisms. Transfer pricing serves the dual purpose of guiding intracompany transfers and providing incentives for upfront investments at the divisional level. When transfer prices are determined through negotiation, divisional managers will have insufficient investment incentives due to "hold-up" problems. While cost-based transfer pricing can avoid such "hold-ups", it does suffer from distortions in intracompany transfers.

Consider a category of product variants distinguished by some attribute such as color or flavor. A retailer must construct an assortment for the category, i.e., select a subset variants to stock and determine purchase quantities for each offered variant. We analyze this problem using a multinomial logit model to describe the consumer choice process and a newsboy model to represent the retailer's inventory cost. We show that the optimal assortment has a simple structure and provide insights on how various factors affect the optimal level of assortment variety.

We describe effective time partitioning heuristics for dynamic lot-sizing problems in multiitem and multilocation production/distribution systems. In a time-partitioning heuristic, the complete horizon of (say) N periods, is partitioned into smaller intervals. An instance of the problem is solved, to optimality, on each of these intervals, and the resulting solution coalesced into a solution for the complete horizon. The intervals are selected to be of a size which permits the use of exact and effective solution methods (e.g., branch-and-bound methods).

In this chapter, we provide a survey of analytical models which can be used to assess the benefits and costs associated with delayed product differentiation in a large variety of settings.

This paper addresses the simultaneous determination of pricing and inventory replenishment strategies in the face of demand uncertainty. More specifically, we analyze the following single item, periodic review model. Demands in consecutive periods are independent, but their distributions depend on the item's price in accordance with general stochastic demand functions. The price charged in any given period can be specified dynamically as a function of the state of the system. A replenishment order may be placed at the beginning of some or all of the periods. Stockouts are fully backlogged.

Generalized knowledge comes from cumulating results across studies, a process known as meta-analysis. Efficiently increasing generalized knowledge in a defined area-estimates of price or advertising, for example-is one important goal for research. Because (1) most meta-analyses are based on highly inefficient and unbalanced natural experiments or designs and (2) additional studies are costly, carefully selecting the next study is important.
