Macroeconomics:

[Md. Alamgir Hossan]

Macroeconomics (from the Greek prefix makro- meaning "large" and economics) is a branch of economics dealing with the performance, structure, behavior, and decision-making of an economy as a whole. This includes national, regional, and global economies.[1] Macroeconomics and microeconomics, a pair of terms coined by Ragnar Frisch, are the two most general fields in economics.[2] In contrast to macroeconomics, microeconomics is the branch of economics that studies the behavior of individuals and firms in making decisions and the interactions among these individuals and firms in narrowly-defined markets.
