Global Shortages During Coronavirus Reveal Failings of Just in Time Manufacturing

“To the extent you can keep reducing inventory, your books look good,” said ManMohan S. Sodhi, a supply chain expert at the City, University of London Business School.

From 1981 to 2000, American companies reduced their inventories by an average of 2 percent a year, according to one study. These savings helped finance another shareholder-enriching trend — the growth of share buybacks.

In the decade leading up to the pandemic, American companies spent more than $6 trillion to buy their own shares, roughly tripling their purchases, according to a study by the Bank for International Settlements. Companies in Japan, Britain, France, Canada and China increased their buybacks fourfold, though their purchases were a fraction of their American counterparts.

Repurchasing stock reduces the number of shares in circulation, lifting their value. But the benefits for investors and executives, whose pay packages include hefty allocations of stock, have come at the expense of whatever the company might have otherwise done with its money — investing to expand capacity, or stockpiling parts.

These costs became conspicuous during the first wave of the pandemic, when major economies including the United States discovered that they lacked capacity to quickly make ventilators.

“When you need a ventilator, you need a ventilator,” Mr. Sodhi said. “You can’t say, ‘Well, my stock price is high.’”

When the pandemic began, car manufacturers slashed orders for chips on the expectation that demand for cars would plunge. By the time they realized that demand was reviving, it was too late: Ramping up production of computer chips requires months.
