Classical define of macro economics

Macroeconomics is a branch of economics that studies the behavior and performance of the entire economy, including topics such as inflation, economic growth, unemployment, and monetary policy. It focuses on analyzing the larger aggregate trends and patterns that affect the entire economic system, rather than individual markets, firms, or households. Macroeconomics considers the interrelationships and interactions among different sectors of the economy, such as consumption, investment, government spending, exports, and imports, and how changes in one sector can impact the others and the overall economy. The objective of macroeconomics is to understand and explain the economic behavior of the economy as a whole and provide policy recommendations to promote stable, sustained, and equitable economic growth and development.
