Title: The Enemies Within: Loyalty, Faction and Elite Competition under Authoritarianism Abstract: Loyalty is a permanent concern to dictators. It is unclear, however, whether loyalty to a dictator is enough to assure the ruling group’s cohesiveness. In this study, we argue that authoritarian elites, while remaining loyal to their superior, often risk group interests to maximize their self-interest under authoritarian competition. Elites within one authoritarian faction thus tend to compete intensely rather than cooperate, in order to outrival their peers. To empirically test our argument, we collect data on Chinese provincial leaders and exploit all media reports in regional newspapers from 2000 to 2014 on corruption investigations and major industrial accidents. We find that Chinese political elites are more likely to promote negative news related to their faction peers than they are to promote similar news regarding other faction members. We also find that negative news reports indeed reduce the promotion probability of reported cadres, while increasing that of reporting ones. (2)时间：2016年12月7日14：00-15：30

Title: Family Background, After-school Tutoring, and Student Achievement: Experimental Evidence from Rural China
Abstract: In this paper, we exploit the “left-behind children” phenomenon caused by massive rural-to-urban migration in China to examine differences in both home learning environment and the heterogeneous treatment effects of an outside after-school tutoring program for children cared by grandparents versus parents. We first develop a simple model in which parents have comparative advantage in tutoring than grandparents and thus spend more time in home tutoring. However, with an increase in the outside after-school tutoring, both types of guardians will substitute their own tutoring inputs away, but the extent of this substitution is much larger for parents than grandparents. We then proceed to an empirical analysis of a randomized cross-age tutoring experiment in which high-achieving 4th and 5th graders provided high-dosage, one-to-one tutoring to low-achieving 2nd and 3rd graders in a rural county in China with a high prevalence of “left-behind children.” We find that the tutoring program significantly improved tutees’ math scores but not Chinese scores, and the test score gains in math are significantly larger for children with both parents absent. Moreover, children cared by grandparents reported little reduction in home tutoring time after participating the outside tutoring program, whereas those cared by parents reported a large reduction in home tutoring time. These findings suggest an important role of family background in affecting the effectiveness of the remedying educational program in the form of after-school tutoring.
