Reserve Bank Governor D Subbarao, today, said a growth rate of 5 to 6 per cent is not sufficient for the economy, which has the potential to grow at double digit rate provided some issues are addressed. Speaking at the IIT Kanpur Alumni meet, Subbarao said there is a need for stable and predictable macroeconomic environment, removal of infrastructure deficit, skill improvement and job creation. He further added there is also need for raising agriculture productivity, and improvement of social sector outcome.
