Speaker: Prof. TU Yundong (Peking University)Venue: Room 206, Building 2, Haina Court, Zijingang CampusAbstract: This paper explores the group structure in large dimensional approximate factor models, which portrays homogeneous effects of the common factors on the individuals that fall into the same group. With the initial principle component estimates, we identify the unknown group structure by a combination of the agglomerative hierarchical clustering algorithm and an information criterion. The loadings and factors are then re-estimated conditional on the identified groups. Under some regularity conditions, we establish the consistency of the membership estimator as well as that of the group number estimator obtained from the information criterion. The new estimators under the group structure are shown to achieve efficiency gain compared to those obtained without this information. Numerical simulations and empirical applications demonstrate the nice finite sample performance of our proposed approach when group structure presents.Contact person: Prof. ZHANG Rongmao (rmzhang@zju.edu.cn)

Speaker: Dr. LI Mingxiang (Nanjing University)Venue: Room 105, Building 2, Haina Court, Zijingang CampusAbstract: In this talk, we will introduce some rigidity theorems on complete and conformally flat manifolds with help of Q-curvature. We introduce a new volume entropy to give a sufficient and necessary condition for the ”normal” metric. Meanwhile, with help of geometric measure theory, we give a distance comparison identity on such manifolds which generalize the result of Li-Tam(1991, JDG) to higher dimensions. Finally, we want to talk about higher order Bol’s inequality which is a joint work with Professor Juncheng Wei.Contact person: Prof. JIANG Wenshuai (wsjiang@zju.edu.cn)

Speaker: Prof. HU Yeyao (Central South University)Venue: Room 102, Building 2, Haina Court, Zijingang CampusAbstract: In this talk, we will first review the resolution of the celebrated Chang-Yang’s conjecture on a sharp Moser-Trudinger type inequality on the two-dimensional sphere. Then we recall the complete theory in dimension one and emphasize the key role played by mean field type equations. Moreover, higher dimensional analogues will be presented and some very recent progress will be introduced. We will also mention some related open problems that the audience might be interested in.Contact person: Prof. JIANG Wenshuai (wsjiang@zju.edu.cn)

Speaker: Dr. Xiaoping Chen (University of Washington)Venue: Room 723, Building A, SOM, Zijingang CampusAbstract: Indirect cronyism is a phenomenon in which managers show favoritism to indirect guanxihu subordinates who have informal, particular, and personal connection with a third party (e.g., another manager) and demonstrate its prevalent existence in Chinese organizations. We explore the crucial factors that may exacerbate managers to engage in indirect cronyism, and the downstream consequences on other members of the organization. We draw on the indirect reciprocity logic embedded in social exchange theory to predict two underlying motives to explain why managers engage in indirect cronyism: (a) fulfilling their felt obligation to favor the indirect guanxihu subordinate, and (b) strengthening their own guanxi with the third party. Results from three scenario-based experiments and one field study sampling a total of 1,559 working adults provide consistent support for our theoretical reasoning and hypotheses. We discuss the theoretical contributions this paper makes to advance the guanxi and cronyism literature, as well as the practical implications of our findings in Chinese organizations and beyond.Profile of the speaker: Dr. Xiaoping Chen is Philip M.
