Even when they inflate and collapse in milliseconds, the same rules apply
PORTLAND, Ore. — Statistically speaking, size doesn’t matter when a financial bubble bursts.
The big crashes may hurt a lot more, but new analyses of “microbubbles” presented March 15 at a meeting of the American Physical Society find that the same mathematical laws underlying massive economic crises are also at work in tiny fluctuations that occur on the order of milliseconds.
The new understanding of economic fluctuations both big and small doesn’t predict when the next economic meltdown will wreak havoc on retirement accounts, said study coauthor H. Eugene Stanley of Boston University. But the results help describe complex financial fluctuations and reinforce the idea that governments ought to have a contingency plan in place for the calamitous collapses that his research describes as inevitable, Stanley said.
The results are intriguing “because what is causing these big bubbles to collapse are some instabilities that
