主   题：Service Design under Collaborative Consumption

Abstract: Consumers often pay for the service that they do not fully utilize. The presence of peer-to-peer sharing opportunity alters consumer usage behavior by enabling owners to rent poorly utilized service on a short-term basis and non-owners to access the service through renting on an as-needed basis. We develop an analytical framework to examine the strategic and economic impact of the sharing option on the firm's optimal versioning strategy in service design. Each service plan is characterized by the maximum amount of service experience a consumer can obtain (service allowance) and its price. Consumers have either high or low valuation for consumption experience, and decide whether to purchase a plan based on their expected personal usage and future sharing opportunity. Hence, sharing option introduces externalities to the consumer choices as the individual service usage depends not only on her own purchase decision but also on others' via the sharing option. Precisely due to this consumption externalities, we find that the optimal service allowance offered to the high-end segment is also lower than the efficient level, in contrast to the classic screening result. With the sharing option, the firm always narrows the gap between service allowance offered to the two segments and provides less total allowance to the market in equilibrium. Our analysis shows that transaction costs in the sharing market have a non-monotonic effect on the firm's versioning strategy, consumer surplus, and social welfare.
