In what respect macro economic is defferent from micro economics
Answers
Microeconomics
Microeconomics is the study of decisions that people and businesses make regarding the allocation of resources and prices of goods and services. This means also taking into account taxes and regulations created by governments. Microeconomics focuses on supply and demand and other forces that determine the price levels seen in the economy. For example, microeconomics would look at how a specific company could maximize its production and capacity, so that it could lower prices and better compete in its industry.

Microeconomics' rules flow from a set of compatible laws and theorems, rather than beginning with empirical study.
Macroeconomics
Macroeconomics, on the other hand, is the field of economics that studies the behavior of the economy as a whole, not just of specific companies, but entire industries and economies. It looks at economy-wide phenomena, such as Gross Domestic Product (GDP) and how it is affected by changes in unemployment, national income, rate of growth, and price levels. For example, macroeconomics would look at how an increase/decrease in net exports would affect a nation's capital account or how GDP would be affected by the unemployment rate.
