That would be, by a breathtaking margin, the bleakest quarter since such records were first compiled in 1947. It would be four times the size of the worst quarterly contraction on record set in 1958.

In just a few weeks, businesses across the country have shut down and laid off tens of millions of workers. Factories and stores are shuttered. Home sales are falling. Households are slashing spending. Consumer confidence is sinking.

As the economy slides into what looks like a severe recession, some economists are holding out hope that a recovery will arrive quickly and robustly once the health crisis has been solved — what some call a V-shaped recovery. Increasingly, though, analysts say they think the economy will struggle to regain its momentum even after the viral outbreak has subsided.

Many Americans, they suggest, could remain too fearful to travel, shop at stores or visit restaurants or movie theaters anywhere near as much as they used to. In addition, local and state officials might continue to limit, for health reasons, how many people may congregate in such places at any one time, thereby making it difficult for many businesses to survive. It’s why some economists say the damage from the downturn could persist far longer than some assume.

There is also fear that the coronavirus could flare up again after the economy is reopened, forcing reopened businesses to shut down again.

The Trump administration takes a rosier view. President Donald Trump told reporters this week that he expects a “big rise” in GDP in the third quarter, followed by an “incredible fourth quarter, and you’re going to have an incredible next year.”

The president is building his reelection campaign on the argument that he built a powerful economy over the past three years and can do so again after the health crisis has been resolved.
