When Milton Friedman pondered what would happen if a helicopter dropped $1,000 from the sky, he likely never imagined that one day a military cargo plane would scatter millions of dollars into one of Bolivia’s largest cities.

But while the Nobel Prize-winning economist worried about the inflation that an influx of cash could generate, the impact in El Alto — where a cash-packed plane crashed and killed 24 people last week while spreading 423 million bolivianos ($62 million) — is one of widespread confusion.

The new currency was legitimately printed, but the central bank has voided its serial numbers to prevent its use. While thousands swarmed the site to pick up the banknotes in one of Latin America’s poorest nations, authorities have tried to burn and destroy the new cash, arresting dozens and raiding homes in a rushed hunt for the missing bills.

That has sent Bolivians into a frenzy. No longer able to quickly tell if a banknote is valid or voided and fearing the crackdown, businesses don’t know what bills to accept anymore, leaving customers frustrated and panicked that their real money is now worthless.

“Just today, everyone refused to take my money five times,” said Yoselin Diaz, 27, who was lining up at the central bank’s main offices in La Paz. “I tried on the minibus and nothing, then I tried to buy some things and nothing, later I went to buy a photo for my father’s grave and even the funeral homes wouldn’t accept it.”

…Bolivia’s central bank has defended its measures to destroy and void the fresh cash, citing not just the principle of keeping stolen money from entering the financial system but also the need to quell social strife. At its height, authorities said about 20,000 people were trying to collect the banknotes as police fired tear gas at them.
