Milton Friedman.
The classical economy defends the economic liberalism advocated initially by Adam Smith. The economist who founded a new classical ecola was Friedman, who created the monetarist school.
As the leader of the Chicago School of Monetary Economics, he revived interest in the quantitative currency theory, which emphasizes the importance of money as an instrument of government policy and as a determinant of economic cycles and inflation.
Friedman was awarded the Nobel Prize for Economics and left a legacy of perscription for the economic policy that revolutionized the organization of central banks around the world.
