Distinguish between Micro and Macro Economics.

Broadly speaking, microeconomic analysis is individualistic, whereas macroeconomic analysis is aggregative. Microeconomics deals with the part (individual) units while macroeconomics deals with the whole (all units taken together) of the economy.

1. Difference in nature: Microeconomics is the study of the behavior of the individual units. Macroeconomics is the study of the behavior of the economy as a whole.

2. Difference in methodology: Microeconomics is individualistic; whereas macroeconomics is aggregative in its approach.

3. Difference in economic variables: Microeconomics is concerned with the behavior of micro variables or micro quantities. Macroeconomics is concerned with the behavior of macro variables and macro quantities. In short, microeconomics deals with the individual incomes and output, whereas macroeconomics deals with the national income and national output.

4. Difference in field of interest: Microeconomics primarily deals with the problems of pricing and income distribution. Macroeconomics pertains to the problems of the size of national income, economic growth and general price level.

5. Difference in outlook and scope: The concept of ‘industry’ in microeconomics is an aggregate concept but it refers to all firms producing homogenous goods taken together. Macroeconomics uses aggregates which relate to the entire economy or to a large sector of the economy. Aggregate demand covers all market demands.

2. Discuss the nature and scope of Managerial Economics. What are the other related disciplines?

Nature and Scope of Managerial Economics:

All managerial decisions are basically economic in nature.
