Three basic types of economic systems
1) To develop some perfective for a study of microeconomics, it helps to begin with a feeling for what an economic system is and how it works.
2) Various countries have elected to use different methods both in organizing resources in the production process and in distributing the resultant goods and services.Three basic types of economic systems stand out.
3) A traditional economic system relies upon custom, habit, social mores, and tried-and-true methods for achieving economic goals; technology is primitive; changes are slow and production is undertaken in the same way is last year and the year before. Tradition and the status quo are perpetuated.
4) A command economic system relies on public ownership and centralized control of the basic means of production; severe limitations are placed upon individual choice when such choices conflict with government-determined economic priorities. Economic plans and activities are under die control of an economic commander-in-chief (a king, czar, prime minister, or central planning authority).
5) A capitalistic or market economic systems emphasizes private ownership, individual economic freedom, competition, the profit motive, and the price systems in the achievement of economic goals. Each economic unit decides what choices and policies are best for it, the thesis being that in encouraging the drive for individual economic self-interest, the outcome proves also to be in the overall best interests of society because of the strong incentives for efficiency, productivity, and satisfaction of consumers.

It will not surprise anybody that Britain has the biggest rainfalls during the month of July and August than at any other time of the year. The geography of Britain can explain to us much about it's weather. English people have such a lot of rain because they live on an island. When it pours with rain we often say: "It’s raining cats and dogs". But we don't Know why and. what the saying's original meaning was. In distant times people thought that witches could turn themselves into cats and ride across stormy skies on their broomsticks and. cats were thought to be a big influence on the weather. The dog was the servant of the Norse storm god, Odin, and represented the wind. Cats and dogs from that time have meant the wind, and. the rain. The umbrella is used as a protection against the rain and. the first man to appear in the street of London with it more than 150 years ago was Jonas Hanway.
