We find that the number of investment alternatives offered, n, and whether the company requires some of the match to be in company stock are key factors of the share of total contributions in company stock. We cannot reject the hypothesis that participants invest 1/n of their contributions in company stock. In addition, participants do not offset an employer match in company stock with a smaller share of their own contributions to company stock, contrary to efficient diversification. Workers also appear to view other plan restrictions as providing cues about the desirability of purchasing company stock. Thus, plan design is very important in determining the share of 401(k) assets in company stock. ER -
