Feedback Trading and the Chinese Put Warrants Bubble
Neil D. Pearson, Zhishu Yang, Qi Zhang, Jul 27, 2022There was a bubble in the prices of put warrants traded on the Shanghai and Shenzhen stock exchanges during the summer of 2007. We use investor trading records from a large securities firm to show that put warrant investors engaged in a particular form of feedback trading. This feedback trading exacerbated an initial run-up in put warrant prices caused by a change in the stock transaction tax, and created the bubble.
What Do a Billion Observations Say about Distance and Relationship Lending?
Haoyu Gao, Hong Ru, Xiaoguang Yang, Nov 07, 2018Using big data of the locations of bank branches and borrowers in China, we document a non-trivial amount of distant lending. The inter-firm network helps banks collect soft information which facilitates the distant lending.

Improving State Effectiveness by Discouraging Civil Servants from Flattering Their Leaders
Alain de Janvry, Guojun He, Elisabeth Sadoulet, Shaoda Wang, Qiong Zhang, Mar 11, 2020Evaluation of public employees performance is essential to induce higher work efforts. We use an experiment in two provinces of china to explore how to design such evaluation. Results show that the incentive effect of evaluation can be larger if the employee does not know ex-ante who the evaluator will be, thus reducing attempts at personally influencing the evaluator and enhancing instead job achievements.
