Description of research

Dr Pillai's research focuses on the economic drivers of technological change. Technical advances in high tech industries are important contributors to productivity growth in the macroeconomy and to improvements in the standard of living. Dr.Pillai studies how economic factors influence the rate at which these technical advances are made, how government policies can influence the rate of technical change, and the welfare impact of these policies. Dr.Pillai's work includes theoretical modeling, econometric estimation of model parameters, and use of estimated models to quantitatively understand the impact of government policies.
