Motivation for Information Exchange in a Virtual Community of Practice: Evidence from a Facebook Group for Shrimp Farmers Guenwoo Lee1 and Aya Suzuki2 May, 2018 PRELIMINARY AND INCOMPLETE PLEASE DO NOT CITE OR DISTRIBUTE WITHOUT PERMISSION Abstract In order to reveal the motivation of information exchanges between farmers, we take a case of one Facebook group, which share a common farming crop and the majority of the members are farmers. We construct a monthly panel data to addresses a Facebook group member's motivation for information exchange between January 2015 and May 2017. Based on Poisson and negative binomial regressions, we found that: (i) members who have previously asked questions are more active in sharing information than people who have never asked; (ii) other members' positive expressions to previous information shared (such as clicking likes) promote future information sharing; (iii) the act of information sharing by one’s peer promote his/her own information sharing, and (iv) the more the member shares information in the past, the more s/he asks information today. These findings suggest that reciprocity does play a significant role in motivating information exchange even in the virtual communities of practice, similar to the communities of practice. We also confirm that professional reputation is one of the motivations for information sharing and that there is a positive effect of peer’s prosocial behavior.
