“Identifying and Decomposing Peer Effects in Decision-Making Using a Randomized Controlled Trial”
Abstract: This paper investigates how firms’ decisions to participate in three one-day seminars on export promotion are affected by their information exchange peers. We find that peers’ participation in the seminars has a positive effect overall. We distinguish between peers participating on the same day and other days, finding that the former has a positive effect while the latter has no significant effect. These results imply that peer effects arise mostly through the reduction of the psychological costs of participation. Our results suggest that multiple equilibria in terms of the share of participants within each network of firms may emerge.

“Accounting for Heterogeneity in the Network Formation Behavior: With an Application to Vietnamese SMEs”
Abstract: In this study, we estimate network formation models, focusing information-sharing link among firms in village-based industrial clusters in northern Vietnam. We apply random coefficients models to network formation models in order to take behavioral heterogeneity into account the link formation. We find that firms are likely to form the link with others with similar firm’s age and manager’s age. In addition, some firms form the link with firm with dissimilar firm’s scale, retailed-oriented firms, and high female work participation, implying that these firms benefit from heterophilous links but others do not.
