The Hidden Cost of Profit Sharing on Participation in Employee Stock Purchase Plans

Many firms use equity-based profit sharing to boost participation in employee stock purchase plans (ESPPs). Using a large panel data set (N=262,824) of a multinational firm, we compare the reactions of former ESPP participants and non-participants to a profit sharing distribution (PSD). We find a dysfunctional effect. Although many former non-participants sign in, almost a similar share of employees leave the ESPP after the PSD. A closer look highlights the importance of social preferences when all employees enjoy profit sharing. Prosocial former participants show a motivational crowding out effect and leave the program, as the equity norm is violated
