Macroeconomics: Understanding the Economy as a Whole

Macroeconomics is the branch of economics that studies the overall performance, structure, and behavior of an economy, focusing on large-scale factors like GDP, unemployment, and inflation. It helps policymakers design strategies for growth, stability, and prosperity by analyzing trends over short, medium, and long time horizons. This field emerged in the 20th century but builds on older ideas to address modern economic challenges.
