Macroeconomics is the branch of economics that looks at human behavior and choices as they relate to the entire economy. Microeconomics deals with human behavior and choices as they relate to relatively small units ---an individual, a firm, an industry, a single market. A macroeconomist would be concerned about questions that impact the whole economy such as, "How will the proposed tax cut affect unemployment, inflation and economic growth?" A microeconomist would ask questions that relate to the various parts that make up the economy such as, "How will the drought impact the price of corn?"
