Abstract ：
The development of the restaurant industry has disrupted food consumption patterns, while evidence on how restaurants impact dietary quality remains limited and inconsistent. This study is one of the first to demonstrate a non-linear, inverted U-shaped relationship between local restaurant density and dietary quality, leveraging data from four rounds of the China Health and Nutrition Survey (CHNS). To mitigate endogeneity issues, our analyses employ a LASSO-selected Instrumental Variable (IV) approach. Our results show that before reaching the threshold, the increase in neighborhood restaurant density, primarily driven by indoor restaurants, leads to improvements in residents' dietary quality. However, once past the threshold, higher restaurant density reduces dietary quality, mainly driven by fast food restaurants. These effects are more pronounced among males with higher-income, and those living in urban and eastern China. The mechanisms underlying these relationships include the increased frequency of eating outside home (OH), with the similar inverted U-shaped relationship observed for dietary diversity further explaining our findings. We recommend supplementing neighborhoods with limited access to dining options through indoor restaurants, and mitigating the negative effects of excessive restaurants density, especially that of fast-food restaurants.

Abstract ：
This paper investigates the cognitive spillover effects of classmates' early childhood education (ECE) experience on junior high school students, using data from the first two waves of the China Education Panel Survey (CEPS). To address potential endogeneity in classmates' composition, we leverage exogenous variation in students' ECE experience generated by random class assignment upon their entry into junior high school. Employing a valueadded model, we find that classmates' ECE experience significantly enhances students' cognitive performance. Specifically, a 10-percentage-point (pp) increase in classmates' ECE enrollment raises students' cognitive scores by 0.08 standard deviations (SD), while an additional year of classmates' ECE experience shows insignificant effect. As to underlying mechanisms, the spillover effects are driven by an improved class environment, increased parental homework support, stronger learning efforts and enhanced non-cognitive skills of students, together with the peer interactions within social networks. Among them, students' behaviors exert the strongest explanatory power of 13 %. Furthermore, the benefits are more pronounced among urban students with ECE experience, those from better-educated families and with moderately below-average baseline cognitive skills.
