Economics is the social science that studies the production, distribution, and consumption of goods and services. The term economics comes from the Greek word oikonomia, ("management of households”) from (oikos, "house") + (nomos, “Custom” or "law"). Thus, it refers to managing a household with limited funds. All economic activities start from the existence of human wants. With the help of resources a person fulfils his wants and gets satisfaction. Thus, economics is the study of wants, efforts and satisfaction. In modern economy, wants, efforts and satisfaction are linked through money. Economics is growing very rapidly as the years pass. As new ideas are being discovered and the old theories are being revised, it is not possible to give a definition of economics which has a general acceptance.
