Merits and Demerits of Macroeconomics
Macroeconomics, as a branch of economics that focuses on the economy as a whole, has both merits and demerits. Understanding these can help in evaluating its significance and limitations.
Merits of Macro Economics
Following are the advantages of the study of Macro-economics.
- Decisions regarding the growth of aggregate saving and investment, reducing tax rates, raising wage rates, control of inflation etc cannot be taken at an individual or micro level. Macro-economic decisions are required to be taken at the national level.

Hence countercyclical measures at the national level may not suit to these micro economic units.
- Stabilization measures at the national level may not have a positive impact on different segments of an economy.
