Bowen Liu is a Research Fellow of Birmingham Business School, University of Birmingham. His research is in the areas of Environmental Economics, Development Economics, Health Economics and Political Economics. His current research focuses on delivering the Strand 5 (Economic strand) of the WM-AIR project that aims at investigating the social and economic impact of air pollution within West Midlands, UK.


PhD in Economics, University of Birmingham, 2021

MSc (Distinction) in Finance and Economics, University of Southampton, 2016


Bowen finished his PhD of Economics from University of Birmingham in 2021. As an Environmental Economist, his PhD research focuses on investigating the effectiveness of air pollution control policies in China. Bowen is interested in policy evaluation using interdisciplinary research method that include Econometrics and Machine Learning algorithms, with particular focus on policies and interventions that promote regional Economic development, Environmental protection and Sustainable development.
