Monetary Revolutions

Daniel Gressel, PhD, Economics (Univ. of Chicago), Milton Friedman, 1976 Nobel laureate in Economics, and Robert Hall PhD Economics (Stanford) discuss the effects that world events, such as world wars and depression, have had on the economies of nations such as Germany and the former Soviet Union. What is the real value of currency in the nations suffering from the effects of hyperinflation and how can the problems of "out of control" inflation be solved?
