This is an unusually weak Planet Money podcast. About 15 minutes of an admittedly interesting tale of 4 Brazilian economists who concocted a seemingly crazy way to ease their countrymen into trusting their new currency after decades of government monetary mismanagement, the oral fine print admitted that oh, by the way, the economists also got the government to balance the budget, eliminating printing money to pay for everything, and peg the new currency to the dollar.
The tricky mechanism was interesting (basically creating a new unit of exchange which is defined as an every increasing number of the current currency units to get the population to start thinking in terms of the new unit of exchange, and then calling the new unit of exchange the new currency), and the lead up story about the horrors of living with hyper-inflation was quite compelling. But no one could blame listeners for coming away with the impression that the cure for hyper-inflation is to induce a temporary mass illusion, rather than actually engaging in the hard work of sound fiscal and monetary policy.
