题目：How to Improve Educational Equity and Reduce Over-Investment: A Multidimensional Contest Experiment

摘要：

Educational equality, as well as education as a channel for promoting economic equality, are among the most sought-after social welfare ideals in countries around the world. However, in practice, competitive environments are often thought to impede progress in realizing these goals. We game theoretically analyze and implement real-effort experiments to study the effect of competition and related policies on educational investments and outcomes. Students from different economic backgrounds engage in competition by exerting effort in learning various subjects and making educational investments, under varying allocation mechanisms, investment costs, examination difficulties and investment limits. Our theoretical model predicts that when everyone's investible funds exceed the equilibrium investment level, competitive behavior is primarily influenced by the cost of investment and the disutility of effort. Our experimental results show that altering investment costs has a limited impact on competitive behavior, whereas employing simpler learning tasks and imposing caps on high investments can more effectively curb over-investment. A policy implication is that to safeguard educational equity, governments may consider assisting low-income families through measures such as tax subsidies, simplifying examinations, and restricting excessive educational spending, although interventions aimed at adjusting educational costs directly show limited effectiveness.
