Research Statement

Research Interests

I am an empirical economist and almost all my research falls into three broad areas of economics (JEL codes are in the parentheses):
  • Industrial Organization (L)
  • Economic Development, Technological Change and Growth (O)
  • Labor and Demographic Economics (J)
The unifying theme behind most of my research is the study of innovation, technological progress and growth. I have explored various aspects of this theme at both micro and macro levels in a number of research projects.
