内容简介： Using a randomized experiment with 3379 parents of high-school students in China, I identify two channels of social influence in parents’ decisions on children’s educational investments: parents adjust their decisions based on other parents’ behaviors because they learn from other parents’ decisions (“social learning”) or because their children are facing competition from peers (“competition externality”). I find that both channels have statistically significant effects on parents’ investment decisions and increase their willingness to buy an educational service by over 20%. Although the average effects of the two channels are not statistically different, the main channels of peer effects are heterogeneous by parents’ educational background: parents with higher education are more likely to learn from peers’ decisions whereas those with lower education are mainly incentivized by the competition externality. These results also shed light on the mechanisms underlying the herding behavior and involution in other settings with competition, such as competitive sports.
