Jianrong Tian
Basically, I'm not interested in doing research and I never have been. I'm interested in understanding, which is quite a different thing. And often to understand something you have to work it out yourself because no one else has done it. — David Blackwell

Working Papers:
(Strong) Implementability with Transfer, latest version, Jianrong Tian and Ju Hu, February 2024.
Previous version circulated under the title ``implementing monotone allocations: a Rochetian approach" (SSRN).
I want to extend a special thanks to Ludvig Sinander, whose excellent and detailed comments are extremely valuable for helping me rethink the contribution of the paper, which gives rise to the latest version. Some sentences in the paper are directly from his comments. Even a new result is found when I think hard on the contribution of the paper as strongly suggested by him. An amazing guy!
Published or Accepted Papers:
Informational Separability and Entropy, pdf, Journal of Economic Theory, Jianrong Tian, Vol. 216, March 2024.
Separable information is mixture of mutual information and loss of diversities; continuous separable information is mutual information. (The main theorems and proofs and the graphical illustration were first presented in 2019 version, in which my focus was rational inattention.)
Optimal Interval Division, pdf, Economic Journal, Jianrong Tian, Vol. 132, January 2022.
Old version(2015) (some typos in the old version are corrected here), "monotone comparative statics for cutoffs" (2016).
