Ragupathy's research focuses on the interface between computation and economics, economic dynamics, discrimination, causal inference, history and methodology of economics.
Dr Ragupathy Venkatachalam joined the Institute of Management Studies in 2016. He has previously taught economics at the Centre for Development Studies, Trivandrum, India and worked as a research fellow at the Artificial Intelligence Economics Research Center at the National Chengchi University, Taiwan.
He obtained his PhD from the University of Trento, Italy and a European Masters in Law and Economics from the University of Hamburg, University of Bologna and Universit茅 Paul C茅zanne Aix-Marseille III. He has an MSc in Economics from the Madras School of Economics, Chennai, India and a BA (Hons) in Economics from Shri Ram College of Commerce, University of Delhi, India. He also serves as the associate editor of Economia Politica [Journal of Analytical and Institutional Economics].
His broad research areas include Endogenous Business Cycle Theory, Computable Economics, Behavioural Economics, Agent-Based Computational Economics and History of Economic Thought. His research focuses on the algorithmic modes of theorizing both at the micro and macro level, incorporating insights from computability theory and constructive mathematics.
