ECONOMICS
1.Economics was defined by Alfred Marshall, one of the great Victorian economists, as "the study of mankind in the everyday business of life". There are other definitions of economics, but Marshall's definition draws attention to the unique feature of human society: that unlike other animals, man provides for his everyday needs by means of a complex pattern of production, distribution and exchange.

2. This everyday business of providing the means of livelihood is called by the general term 'economy'. Economics is the study of economies, and in particular of modern economies such as those of Western Europe and the USA. It is interesting to study primitive economies, but it is the advanced economies that interest us most.
3 How do we produce all the things that we need? How do we distribute the products among the various groups in the society? What institutions have we developed to promote economic activity, and how does each institution play its part in the intricate relationships of everyday life?
4. The economic systems fall into three categories, they are traditional economies, controlled economics and free economies. In fact most countries must be, to some extent, mixed economies. It is impossible for bureaucracy to supervise every aspect of production in the countries of controlled economies while the monopolistic exploitation of the mass of any people in a truly 'free enterprise' system is totally unacceptable in the modern world.
