Macroeconomy refers to the study of the overall performance, structure, and behavior of an economy as a whole. It focuses on large-scale economic indicators such as GDP (Gross Domestic Product), inflation, unemployment, and economic growth. Macroeconomics examines how factors like government policies, monetary systems, and global economic trends impact the functioning of national and international economies. Understanding macroeconomics helps policymakers, businesses, and individuals make informed decisions about resource allocation, investment, and economic policy.
