Domingo Cavallo

"In the early years of the twentieth century, Argentina was one of the richest countries in the world. Then came many years of failed policies, and Argentina retreated to the status of a middle-income country. […] Things changed in 1991 when Domingo Cavallo (an economics Ph.D. from Harvard) took over as economy minister. Argentina implemented an array of promarket economic reforms, including a currency-board type of monetary system."
