Abstract
The research studies parent’s beliefs about their investment in extracurricular activities and the implications in student competition, anxiety and educational inequality in China. To compete for limited educational opportunities such as admissions to elite schools, when making educational investments, parents would not only consider their children’s own ability, but also other parents’ behavior. However, due to lack of information, parents might have biased beliefs about the relative level of their investments, which could lead to a suboptimal level of investment as well as excessive anxiety. This study intends to conduct a randomized controlled trial among elementary and middle school parents in a major city in China to examine parents’ beliefs about their relative educational investments. Specifically, the following three research questions will be explored: 1) whether parents consider others’ behavior when making education investments; 2) whether parents have biased beliefs about others’ investment behavior; and 3) when information was given, whether their beliefs and behavior in educational investment would be affected.

Experimental Design

Experimental Design
The experiment design includes three stages. In the first stage, parents of students in cohorts t, t+1, and t+2 are surveyed about the average time their children spent in three types of extracurricular activities (i.e. math, English, and sports and arts). In the second stage of the experiment, parents in cohorts_t+1,t+2 are randomly assigned to (1) information treatment in which they are presented with average weekly hours spent in three types of extracurricular activities by students in cohort_t. Parents also choose their reference group (the overall average or average of the high-performing students) before the information is presented; (2) common knowledge information treatment in which the information presented is exactly the same as the information treatment, except that a common knowledge reminder - "This information will be shared to all parents in your cohort" - is added; (3) no information. In the third stage, parents in cohorts t+1 and t+2 will be surveyed again about their actual investment in their children's extracurricular activities.
