Macroeconomics studies the economy in general by analyzing the determination and behavior of large aggregates such as income and products, price levels, employment and unemployment, currency stock, interest rates, balance of payments and exchange rates. The macroeconomic approach may omit important factors, but it establishes relationships between large aggregates and allows to understand some relevant interactions. Macroeconomics is concerned with short-term aspects such as unemployment, for example.

Macroeconomics has some goals such as increasing the level of jobs, stabilizing prices, distributing income, growing the economy, resolving conflict of objectives.
