ECONOMICS:

 

Economics is the social science that studies the production, distribution, and consumption of goods and services. The term economics comes from the Ancient Greek οá¼°κονομία (oikonomia, "management of a household, administration") from οἶκος (oikos, "house") + νÏŒμος (nomos, "custom" or "law"), hence "rules of the house(hold)". Current economic models developed out of the broader field of political economy in the late 19th century, owing to a desire to use an empirical approach more akin to the physical sciences.

A definition that captures much of modern economics is that of Lionel Robbins in a 1932 essay: "... the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses. Scarcity means that available resources are insufficient to satisfy all wants and needs. Absent of scarcity and alternative uses of available resources there is no economic problem. The subject thus defined involves the study of choices as they are affected by incentives and resources.

 

Economics aims to explain how economies work and how economic agents interact. Economic analysis is applied throughout society, in business, finance and government, but also in crime, education, the family, health, law, politics, religion, social institutions, war, and science. The expanding domain of economics in the social sciences has been described as economic imperialism. Ref: http://en.wikipedia.org/wiki/Economics
