Mr. Ahluwalia said that desired growth rate can not be achieved without investments in this vital sector. He said, there is a need to experiment in social sector particularly in health and education.Mr. Ahluwalia urged the Finance Ministry to examine the possibility of setting up Infrastructure Debt Funds to fund core sector development activities.
