Meaning: -The term Macro is derived from Greek word “Makros” which means large. It is the branch of economics, which studies the behaviour of all economics units combined together. Macroeconomics is a study of aggregates. It is the study of the economic system as a whole. Therefore, it is also called as Aggregate Economics.
Definition: -“Macroeconomics deals not with individual quantities as such, but with aggregates of these quantities; not with individual incomes but with the national incomes; not with individual prices but with the price level; not with individual outputs but with the national output’.
