Effects of On‐Demand Product Adjustments on Firm's Pricing and Product Strategies
研究企业具备按需调整产品质量的能力（OPAC）时，如何影响其最优定价和产品线决策，发现OPAC并非总能提升利润，且可能减少服务消费者细分市场，但会提高高低端产品质量。
In many markets, consumers have time‐varying needs for product or service quality. Recent technology advances equip firms with the on‐demand product‐adjustment capability (OPAC), which allows them to efficiently process customers' requests for short‐term (e.g., daily or hourly) changes of service quality to meet their time‐varying demands. This paper examines how OPAC affects a firm's optimal pricing and product‐line decisions in a market with consumers having time‐varying product needs and different average need levels. OPAC gives the firm a new way to price discriminate consumers—having a targeted consumer use a low‐end product in her low‐need state and upgrade to a high‐end product in her high‐need state; this contrasts the traditional use of a product line to segment consumers based on their expected valuations, that is, average need levels, whereby each consumer uses only one product and cannot flexibly adjust the product quality over time. We show that OPAC does not always improve the firm's profit: it does so only when consumers' valuations vary significantly over time or when each segment of consumers with different probabilities of having a high valuation is not too small. Moreover, although OPAC enables the firm to provide additional options to serve more consumer segments, it may actually induce the firm to optimally serve fewer consumer segments. One may intuit that OPAC would induce the firm to reduce the low‐end product's quality to elicit more upgrades; our analysis shows that, interestingly, OPAC can lead to an increase in quality for both high‐end and low‐end products.
