Macroeconomics is the branch of economics that studies the behavior and performance of an entire economy, rather than individual markets or consumers. It takes a top-down view, focusing on aggregate indicators such as Gross Domestic Product, unemployment rates, and inflation to measure the nation's economic health and growth. The primary goals of macroeconomic policy are to achieve sustainable economic growth, price stability and full employment. To steer the economy toward these goals, governments and central banks utilize two main tools: fiscal policy and monetary policy.
