Unlike in countries such as the US where people buy food after getting cash transfers, the scenario is different in India. "In India, we have a public distribution system which provides food to the people. So, people in our country resort to precautionary motive due to uncertainty," he said.
According to him, this uncertainty arising out of the health factor will stay until a vaccine for Covid-19 is developed, and spending will not pick up till then.
"People will save more and the right time for increasing demand is when uncertainty is not there", Subramanian said.
He said the government is cognizant of the fact that there is a need to increase demand in the economy. He said that the Jan-Dhan account holders have a high marginal propensity to consume, though they are saving more at the moment.
Regarding the Rs 20-lakh crore financial package announced by the government, Subramanian said elsewhere, in the world, particularly in countries such as the US and the UK, the fiscal component in the stimulus packages was 3.5 per cent, the balance being monetary and liquidity measures.
"India has exactly done that," he added.
He said that the health sector is now seeing a spurt in demand due to the pandemic while the tourism and hospitality segments have been suffering.
