The term ‘macro’ was first used in economics by Ragner Frisch in 1933. But as a methodological approach to economic problems, it originated with the mercantilists in the 16th and 17th centuries. They were concerned with the economic system as a whole. From the 18th century physiocrats to modern economists have contributed to the development of macro economic analysis. But credit goes to Keynes who finally developed a general theory of income, output and employment in the wake of the great depression.
