This is a story about how an economist and his buddies tricked the people of Brazil into saving the country from rampant inflation. They had a crazy, unlikely plan, and it worked.
Twenty years ago, Brazil’s inflation rate hit 80 percent per month. At that rate, if eggs cost $1 one day, they’ll cost $2 a month later. If it keeps up for a year, they’ll cost $1,000.
In practice, this meant stores had to change their prices every day. The guy in the grocery store would walk the aisles putting new price stickers on the food. Shoppers would run ahead of him, so they could buy their food at the previous day’s price….
This is a terrific story and a model for good journalism.
