Unlike most economists who tend to find it tough to clamber off the fence, Dr C Rangarajan is always clear on the key issues on hand and hardly hesitates to state them. These, even as, he maintains the study in caution that one may expect from a numbers-driven former central banker. Economist and former governor of the Reserve Bank of India, Dr Rangarajan, has for some time now maintained that if India aspires to be counted among the developed nations, it will need to grow at over 7 per cent each (if not 8 per cent) year consistently for the next two decades. But for this, he feels, it will first need to raise the investment rate in the country to 35 per cent of the GDP, which is two per cent more than the current rate but till such time, the central government much keep up the tempo of its capital expenditure.
