Macroeconomics is the branch of economics that examines the functioning and performance of an entire economy, focusing on aggregate indicators such as gross domestic product (GDP), unemployment rates, inflation, and national income. This course explores how economies grow and fluctuate over time, the impacts of government fiscal and monetary policy, and the factors influencing aggregate demand and supply. Students will learn to analyze economic trends, evaluate policy effectiveness, and understand the interdependencies between national and global economic systems. Key topics include economic growth, business cycles, inflation, unemployment, and the role of central banking in stabilizing economies.
