What is macroeconomics?

The area of ​​the economy known as macroeconomics focuses on the behavior of the national economy or the regional economy as a whole. Macroeconomics is a very general field, which mainly concerns large -scale indicators, such as the unemployment rate, and the creation of models to explain the relations between these indicators. It is also considered to be a supplement to microeconomics that studies individuals rather than larger standards. Until then, economists did not take into account individual activities from the behavior of the national economy as a whole. John Maynard Keynes, a British economist and other economists who worked on explanation of the causes of great depression, were particularly influential in the development of macroeconomics.

Keynes' theories dominated until recently. Keynesiani relied on aggregated demands were central to macroeconomics, for example, how to explain the levels of unemployment. At the end of the 80s, Keynesian economists have come to terms with classical economists, a significant struggle in which economists of workIf the microeconomic models with those that have evolved into macroeconomics. While Keynesian models are no longer the basis of the field, current models are strongly influenced by their Keynesian predecessors. So far, no economic school of thought has developed a model that completely and precisely reproduces the functioning of the economy, leading to various conclusions. However, with regard to the theories of each, the economist can enable the economist to develop a work approach to the field.

Macroeconomics study has led to the use of government policies to carry out economic change, with the hope of avoiding depression and other economic shocks. Two key tools used to manage the national economyes are fiscal and monetary policies. Politics developed from this area of ​​the economy have wide effects - as a rule, they are a policy that makes evening news.
