macroeconomics

n. branch of economics which studies a nation's economy as a whole

Macroeconomics is a branch of economics that deals with the performance, structure, and behavior of a national economy as a whole. Macroeconomists seek to understand the determinants of aggregate trends in an economy with particular focus on national income, unemployment, inflation, investment, and international trade. In contrast, microeconomics is primarily focused on the determination of prices and the role of prices in allocating scarce resources.

Analysis of a country's economy as a whole.

The subdivision of the discipline of economics that studies and strives to explain the functioning of the economy as a whole -- the total output of the economy, the overall level of employment or unemployment , movements in the average level of prices (inflation or deflation ), total savings and investment , total consumption and so on. The focus of much of macroeconomic theory is analysis of the ways in which conscious government policies (and the unintended secondary consequences of these policies) can influence the overall "economic health" of the country for good and for ill.
