Micro Economics

The word ‘micro’ means a millionth part. Micro economics is therefore the study of small parts of the economy. It studies the economic motives and behaviour of individual consumers and producers, and the principles involved in organizing and operating individual firms and industries. It studies how individual consumer, firm and industry attain equilibrium or optimum positions. A.P. Lerner says: “Micro economics consists of looking at the economy through a microscope, as it were, to see how the millions of cells in the body economic-the individuals, or households as consumers, and the individuals or firms as producers-play their parts in the working of the whole economic organism”.
