Macroeconomics:

Macroeconomics (from Greek prefix "makros-" meaning "large" + "economics") is a part of economics dealing with the performance, behavior, decision-making and structure of an economy as a whole, rather than single markets. This adds national, global and regional economies. With microeconomics, macroeconomics is one of the two most basic fields in economics.

Macroeconomists study aggregated denotes such as GDP, unemployment rates, and price indices to understand how the complete economy functions. Macroeconomists create models that explain the relationship between such factors as national income, consumption, output, unemployment, inflation, savings, international trade, investment and international finance. Microeconomics is primarily focused on the actions of individual agents, such as consumers and firms, and how their behavior calculates prices and quantities in definite markets. While macroeconomics is a wide field of study, there are two main areas of research that are emblematic of the discipline: the attempt to study the causes and consequences of short-run fluctuations in national income, and the attempt to study the determinants of long-run economic growth. Macroeconomic models and their forecasts are used by both governments and big corporations to assist in the evaluation and development of economic policy and business strategy.
