Title： The Promise and Perils of Collaborative Consumption

Abstract：We are witnessing a paradigm shift away from the exclusive ownership and consumption of resources to one of shared use and consumption. This paradigm shift is taking advantage of innovative new ways of peer-to-peer sharing that are voluntary and enabled by internet-based exchange markets and mediation platforms. Value is derived from the fact that most resources are acquired to satisfy peak demand but are otherwise poorly utilized (e.g., the average car in the US is used less than 10 percent).  However, increased collaborative consumption may have other consequences, some of which may be undesirable. For example, greater access to cars could increase car usage and, therefore, lead to more congestion and pollution if it is not accompanied by a sufficient reduction in the numbers of cars. This could occur if sharing leads to speculative investments in cars and price inflation, or if yet it affects the availability and pricing of other modes of public transport (e.g., taxis, buses, and trains). Collaborative consumption raises several important questions. How does collaborative consumption affect ownership and usage of resources? Is it necessarily the case that collaborative consumption leads to lower ownership, lower usage, or both (and therefore to improved sustainability)? If not, what conditions would favor lower ownership, lower usage, or both? How would the platform set prices, commissions, and membership fees and under what conditions would choices for these parameters lead to socially desirable outcomes? To what extent would a private platform (a platform that maximizes its own profit) improve social welfare? How far would the resulting social welfare be from that obtained under a public platform (a platform that maximizes social welfare)? What public policies, if enacted, would ensure that collaborative consumption would lead to higher social welfare? In this paper we address these and other related questions in the context of peer-to-peer car sharing.

Title： Mitigating Supply Uncertainty: The Interplay Between Diversification and Pricing

Abstract：We consider a firm's sourcing problem from one reliable supplier and one unreliable supplier in two price setting scenarios. In the committed pricing scenario, the firm makes the pricing decision before the supply uncertainty is resolved. In the responsive pricing scenario, the firm's pricing decision is made after the supply uncertainty is resolved. For the committed pricing scenario, we develop a rather general condition on supply uncertainty that guarantees the unimodality of the firm's objective function. By comparing the firm's optimal diversification decisions in the two pricing scenarios, we examine the interplay of supply diversification strategy and responsive pricing strategy in mitigating supply uncertainty. While both strategies are effective in mitigating supply uncertainty, we show that they are not necessarily substitutes. The relationship between these two strategies depends on two adverse effects caused by supply uncertainty: the lost-revenue effect and the lost-goodwill effect. More specifically, when the lost-revenue effect dominates the lost-goodwill effect, these two strategies are complements; otherwise, they are substitutes. Finally, we examine the impact of market size, price sensitivity, supplier reliability, and failure rebate on the interplay between these two strategies, and discuss the implications of our results.
