The proposed stimulus package will generate demand by infusing liquidity into the system and thus perk up the economy, the CEA said.
"A good part of stimulus is utilising leverage to deliver...while at the same time ensuring that the fiscs remain actually under control," he said.
Last week, the government raised its market borrowing programme by a whopping 54 per cent of the Budget estimate to Rs 12 trillion for the current fiscal to fund a comprehensive stimulus package of Rs 20 trillion to fight the Covid-19 crisis.
According to some estimates, Rs 4.2 trillion additional borrowing by the government will push the fiscal deficit to 5.8 per cent of the GDP in FY21 as against the budget target of 3.5 per cent.
With regards to proposed structural reforms, Subramanian said Prime Minister Narendra Modi in his recent address touched some important aspects like land, labour, laws and liquidity.
"Land and labour are really factor market reforms because these are factor inputs that really affect the cost of doing business and you have seen a lot of changes on these recently at state level," he said.
Uttar Pradesh, Madhya Pradesh and Gujarat have announced fundamental labour reforms and other states are also in line to follow up, he said, adding, Karnataka had just gone ahead and changed the regulation on acquisition of land for business.
Land can now be directly bought from farmers in the state and other states will also imbibe the model, he said.
"Land and labour are state-level subjects. What the PM has outlined is what states are implementing. I think from the perspective of the cost of doing business, these are very important," he said.
On growth he said, India will witness a V-shape rebound rather than U-shape post the Covid-10 crisis.
"It is possible that there may be a lot of pessimistic assessments, I would rather be aware of that bias while making judgement. When you look at researches around Spanish Flu of (1918), it was far more devastating. even then it was V shaped recovery," he said.
That is the best estimate that one can make at this point of time, he said.
Pointing out that the Spanish Flu was far more devastating than the current Covid-19 crisis, he said, that flu had affected one-third of the global population in contrast to one per cent now by coronavirus
and despite all that it was a V-shaped recovery then.
