Abstract: This paper investigates peer effects on firm managers’ decisions. We invited 131 randomly selected firm representatives to three one-day seminars on export promotion. We found that peers' invitation in the seminars has a positive effect on firms' participation. We distinguish between peers' invitation 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 a reduction of psychological cost of participation. Our results suggest that multiple equilibria in the share of participants within each network of firms may emerge.
