SMU Professor of Economics Shurojit Chatterji designs mechanisms that countries can use to allocate their scarce resources more fairly and efficiently. In mechanism design, researchers investigate methods that can elicit true preferences from individuals or economic agents. To find robust mechanisms that resist manipulative behaviour, Prof Chatterji applies two specific methods: randomisation and restricting preferences. Apart from fitting randomisations or preference restrictions into mechanisms, Prof Chatterji also studies ways to make mechanisms implementable in real life situations.
