Wei Bi completed his PhD in Economics at the Paris School of Economics. His primary research interests lie in the area of microeconomics theory, which includes game theory, bounded rationality, industrial organization, and behavioural economics.

As a Max Weber Fellow, he will continue to explore his research in two directions: i) how cognitive distortions bias agents' behaviour and ii) applying game theory in the study of industrial organization. He is interested in the mistakes that people make when taking action. Some mistakes are just carelessness. Others are worthy of attention, such as reverse causation, illusory correlation, and bounded rationality. Additionally, there is huge potential for applying economic theories in the studies of industrial organizations, such as advertising, research and development, and predatory pricing.

Wei spent two years as a lecturer (ATER) at ENS Paris-Saclay, teaching undergraduate courses, including international trade, and graduate courses, including decision theory, game theory, dynamics modelling, and public economics.
