Speaker: Associate professor LI Sai, Renmin University of ChinaTime: 14:00, March 8Venue: Room 1417, Administrative Building, Zijingang CampusAbstract: We study estimation and inference for high-dimensional linear models with two types of “proxy data”. The first type of proxies encompasses marginal statistics and sample covariance matrices computed from distinct sets of individuals. We develop a rate optimal method for estimation and inference for the regression coefficient vector and its linear functionals based on the proxy data. We show the intrinsic limitations in the proxy-data based inference: the minimax optimal rate for estimation is slower than that in the conventional case where individual data are observed. The second type of proxy data is differentially private data. We propose method for private estimation and inference in high-dimensional regression with FDR control.

Presenter: Lars-Erik Cederman (member of the German National Academy of Sciences)Discussant: Prof. Kurtuluş Gemici, Prof. Andre PythonVenue: Room 1127, Block A, Creative Building, West Zone, Zijingang CampusAbstract:Does the partitioning of states along ethnic lines reduce conflict? While theorists drawing on the “security dilemma” argue that partition prevents conflict recurrence by separating the parties, others dispute these findings. Advancing in four analytical steps, this work first reconceptualize partition as decreased cohabitation in dyads between transnationally defined ethnic groups. Based on a global dataset (1945-2017), we find that whereas complete partition reduces internal conflict, its incomplete application increases this risk. The second step adopts a nationalist logic and tests whether partition reduces conflict if it eliminates dyadic domination. Third, the analysis focuses on whether reduced domination makes civil conflict less likely, with or without border change. We show that power sharing can be at least as effective in reducing domination as partition. The fourth and final step investigates the various side effects of state splits on both civil and interstate conflict. Generally, we find that partition may fuel instability both within and outside the dyad.

Speaker: Prof. WU Kaishu (University of Waterloo)Host: Prof. WANG Wenming (Zhejiang University)Venue: A423, School of Management, Zijingang CampusAbstract: Environmental taxation aims to improve firms' environmental performance by increasing the cost of polluting. We find that highly polluting Chinese firms increase income tax avoidance to offset additional costs caused by China's Environmental Protection Tax Law. This effect is stronger for firms with greater financial constraints, firms in provinces with higher environmental tax rates and greater emphasis on environmental protection and firms with lower income tax avoidance prior to the law. Further, while the environmental tax on average improves polluting firms' environmental performance at the cost of their financial performance, these effects are muted for firms that increase income tax avoidance. Overall, our findings suggest that the role of environmental taxation in promoting environmental sustainability is undermined by firms' income tax avoicance. Our study provides important policy making implications by identifying an unintended consequence of environmental taxation and showing how different taxes interact with each other.

Speaker: Prof. HAN Weimin, Department of Mathematics, University of Iowa, Iowa City, IA 52242, USAVenue: Room 105, Building 2, Haina Court, Zijingang CampusAbstract: Recently, studies of hemivariational inequalities have attracted much attention in the research communities. Hemivariational inequalities are generalizations of variational inequalities. Through the formulation of hemivariational inequalities, application problems involving nonmonotone, nonsmooth and multivalued constitutive laws, forces, and boundary conditions can be treated successfully.In this talk, we introduce models of hemivariational inequalities in fluid mechanics, and present recent and new results on well-posedness analysis and mixed finite element methods for the Stokes and Navier-Stokes hemivariational inequalities.Contact person: Prof. CHENG Xiaoliang, Prof. LIANG Kewei
