Nobel laureate economist Abhijit Vinayak Banerjee on Thursday apprehended that the impending third wave of the Covid-19 pandemic might adversely impact the GDP, and its growth rate might go down to 7 per cent, even below the IMF's recent projection of 9.5 per cent.

Banerjee, who heads West Bengal's Global Advisory Board (GAB) and advises the state government on issues related to the pandemic, said that boosting the state's economy is directly related to the revival of the country's economy as it is under stress due to the ongoing pandemic situation.

"The economy is going slow due to the Covid situation. Earlier the IMF had said GDP growth would be 12.5 per cent. Now it is saying it would be 9.5 per cent. I apprehend it might go down to 7 per cent. Another wave will decrease it further. If the country's economy does not improve, the state will not be able to move forward alone," he said.

Last month, the International Monetary Fund (IMF) cut its economic growth forecast for India to 9.5 per cent for the fiscal year to March 31, 2022, as the onset of a severe second Covid-19 wave cut into recovery momentum.

This forecast for 2021-22 is lower than the 12.5 per cent growth in GDP that IMF had projected in April before the second wave took a grip. For 2022-23, IMF expects economic growth of 8.5 per cent, higher than the 6.9 per cent it had projected in April.

"The economy of Bengal is also connected with the country. If the country's economy does not improve, Bengal alone will not be able to do anything. If the economy of the whole country is active, it will have an impact.

"Many Bengalis work in other states. A lot of income comes from migrants. We cannot solve this problem alone. When the country's economy opens, that will pull us. The state government is certainly trying to help, but the problem will be solved only when the country's economy recovers," Banerjee said.

The noted economist that the Centre should be more into free-spending policies like other economies of Europe and the US rather than being more concerned about balancing the deficit and the budget.

"The (union) government has a fiscal problem, and it may have more faith in balancing the budget than free-spending policies. The government is trying to use the one instrument it has as other forms of tax collection are not necessarily keeping pace, given the economy is slow. It is using this to balance the budget," he said when asked to react to the Centre's decision to increase cess on various items, including fuel, from time to time in the last year.

But this is not the direction the government should not have taken, Banerjee said.

"I think the government should have been more open-handed with the spending. I have said this many, many times. I think the central government is too unwilling to do what US or European economies are doing - printing money and spending. And I think that would have been a better policy in the present context," the economist said.

Banerjee, however, praised the Centre for now moving in that direction.

"The inflation is already up due to the high fuel prices. I think there is a good case for being more open-handed. But to be fair, the central government has now moved towards that direction and have announced several relaxations. I think being less mindful of the deficit might be the right strategy," the Nobel laureate said.
