Computational Economics Group


About Us

We are a group of computer science researchers interested in problems emerged at the interface of computer science and economics. The group has been founded since 2012 by Prof Pingzhong Tang at the Institute for Interdisciplinary Information Sciences, Tsinghua University.

Our current areas of research involve different aspects of computational economics, including auction, market design and matching markets.

Pingzhong Tang

Pingzhong Tang Assistant Professor

I am National Youth-1000 assistant professor at IIIS (Yao class) Tsinghua University.

Before coming to Tsinghua, I was a postdoc at EM Lab, CSD, Carnegie Mellon University, 2010-2012

I completed PhD in CSE, HKUST, 2010 and bachelor in CS, USTC, 2005

I was on sabbatical at Simons Institute, UC. Berkeley, 2015. During my PhD study, I was exchange student at EconCS group Harvard and Multiagent lab Stanford

I have been a senior consultant of Baidu on their next generation of dynamic keyword auction design. I have also served as the chief consultant of iPin – an AI-powered college application app. Back in 2013, I was a visiting professor at Microsoft research Asia.

I am on SPC and PC of EC-16, IJCAI-16, AAAI-16. Past SPCs and PCs: AAAI-12, -13, -15 AAMAS-12, -13, IJCAI-11, -13, -15, UAI-14

In Tsinghua, I teach Economics and Computation (Fall, grads) and Game Theory (Spring, undergrads) alternately.

Research interests: Multi-agent System, Electronic Commerce, Machine Learning, Optimization, Recommendation, Auction and Mechanism Design, Market design, Game Theory
