Learning from Coworkers: Peer Effects on Individual Investment Decisions

Paige Ouimet and Geoffrey Tate

Journal of Finance, 2020, vol. 75, issue 1, 133-172

Abstract: Using unique data on employee stock purchase plans (ESPPs), we examine the influence of networks on investment decisions. Comparing employees within a firm during the same election window with metro area fixed effects, we find that the choices of coworkers in the firm's ESPP exert a significant influence on employees’ own decisions to participate and trade. Moreover, we find that the presence of high‐information employees magnifies the effects of peer networks. Given participation in an ESPP is value‐maximizing, our analysis suggests the potential of networks and targeted investor education to improve financial decision‐making.
