Macroeconomics
Study of an economy as a whole
Macroeconomics is a branch of economics that deals with the performance, structure, behavior, and decision-making of an economy as a whole. This includes regional, national, and global economies. Macroeconomists study aggregate measures of the economy, such as output or gross domestic product (GDP), national income, unemployment, inflation, consumption, saving, investment, or trade. Macroeconomics is primarily focused on questions that help to understand aggregate variables in relation to long-run economic growth.
