Introduction
Recent years have witnessed a rapid growth in sharing service businesses. In B2C sharing-service businesses such as Zipcar, customers share goods and services provided by a service firm with other customers and perform the roles played by service employees in traditional service businesses. Consequently, how well one customer carries out expected tasks influences the quality of service provided to other customers. Extant studies have emphasized the importance of a governance system to prevent such a social dilemma as the personal interest of an individual being pursued at the sacrifice of the interest of the community. However, few studies have empirically examined the effect of different design of a governance system. To fill this gap in the research, this study examines the framing effect of customer messages on customer intention to cooperate by complying with the request by the firm.
Theoretical development
For customers to be willing to cooperate with a firm, they have to be first motivated to do so. The framing effect of on customer motivation has been well demonstrated (Ganzach & Karsahi, 1995) in diverse service contexts such as healthcare (Christensen, Heckerling, Mackesy, Bernstein, & Elstein, 1991), education (Fryer Jr, Levitt, List, & Sadoff, 2012), and consumer behaviors (Ganzach & Karsahi, 1995; White, MacDonnell, & Dahl, 2011) In the context of service consumption, motivation is defined as the inner driver that triggers an individual to cooperate with the service providers (Tsai, Wu, & Huang, 2017). Whether messages were framed as a gain versus a loss exerted a significant impact on consumer motivation. In the consumer behavior contexts, consumer reactions to frames were mixed (Ganzach & Karsahi, 1995). In this study, we will examine the framing effect in the context of sharing service consumption. H1: In the B2C sharing service context, the framing of customer message (gain vs. loss) will affect customer motivation to comply with the request of the service firm. Customers tend to behave different depending on the value they pursue through consumption (Hwang & Griffiths, 2017). Even in the same consumption context, values of customer pursuit can vary widely. Hence, we intend to examine the moderating effect of customer value perception of sharing service on the effect of message framing on motivation. Studies showed that customers pursuing utilitarian values consider monetary savings and convenience as important, while customers pursuing symbolic value consider status and self-esteem as important and those pursing hedonic values consider entertainment and exploration as important (Rintamäki, Kanto, Kuusela, & Spence, 2006). The framing effect was shown to differ by the emphasized value of the product in the context of advertisement. A gain frame was more effective than a loss frame when the ad highlighting the hedonic attributes of a product while a loss frame was more effective when the ad stressing the utilitarian attributes of the product (Lin, 2007). Taken together, we conjecture that customers pursing different values will react differently to the same frame of messages and the level of motivation triggered by the same message frame will also differ.
H2: Customer value perception of sharing service will moderate the framing effect of customer messages (gain vs. loss) on motivation. Specifically, customers pursuing utilitarian values will react more strongly to the messages framed as a loss (H2a), while customers pursuing hedonic or symbolic values will react more strongly to messages framed as a gain (H2b).
The effect of motivation on customer behaviors and behavioral intentions have been well demonstrated (Ganzach & Karsahi, 1995). In the service context, customer cooperation behaviors induced by motivation significantly influence the efficiency of service operations (Mills & Morris, 1986). We propose that the motivation enhanced by customer messaged influence customer willingness to cooperate.
H3: In the B2C sharing service context, motivation affects customer willingness to cooperate.
Methodology
Data will be collected from American consumers who have used a car sharing service at least once in the past one year through an online scenario-based survey using a 2 (message frames: gain vs. loss) x 3 (values of sharing service: utilitarian vs. hedonic vs. symbolic) between-subject experimental design. Hypotheses will be tested by an analysis of variance and a regression analysis.
Implication
The findings of this study will help P2P service firms better design customer messages in inducing customer cooperation and how to customize the design by customers’ value perceptions of sharing service.
