It explains and analysis how a country can gain from international trade. Price mechanisation or the market forces of demand and supply determines prices of goods and services without any government intervention. These externalities may be in the form of either external economies or external diseconomies. It shows how the relative prices of various products and factors are formed, that is, why the price of cloth is what it is and why the wages of an engineer are what they are and so on. Report a Violation, Interdependence between Micro and Macro Economics, Microeconomics: Useful notes on Microeconomics (With Diagram). Microeconomic theory shows that welfare optimum of economic efficiency is achieved when there prevails perfect competition in the product and factor markets. Economics, thus, has descriptive, normative and predictive aspects.” We have noted above that microeconomics reveals how a decentralized system of a free private enterprise economy functions without any central control. The study of behavior of individual units provides the base for understanding the behavior of aggregates. This vast task can be achieve and in the past has been achieved, only by the development of a decentralized system whereby the millions of products and consumers and induced to act in the general interest without the intervention of anybody at the centre with instructions as to what one should make and how and what one should consume.”. MIcroeconomics has great uses. The importance of microeconomics can be analyses on the basis of following headings: Copyright 10. Further, microeconomic analysis is applied to show the gain from international trade and to explain the factors which determine the distribution of this gain among the participant countries. Micro economics explains the operating of a free enterprise economy where the individual has the freedom to take his own economic decisions.All economic decisions such as what, how, how much, where, when. Microeconomics occupies a vital place in economics and it has both theoretical and practical importance. Further, it tells us how the goods and services produced are distributed among the various people for consumption, through price or market mechanism.

It is in this context that a large part of microeconomic theory is concerned with showing the nature of departures from perfect competition and, therefore, from welfare optimum (economic efficiency). He writes, “Microeconomic theory facilitates the understanding of what would be a hopelessly complicated confusion of billions of facts by construction simplified models of Behaviour which are sufficiently similar to the actual phenomena to be of help in understanding them. It not only analyses economic conditions but also studies social needs under different market conditions like monopoly, oligopoly etc. These would have to include directives for adjusting to continual charges in the availabilities of millions of productive resources and intermediate products, in the known methods of producing everything everywhere, and in the quantities and qualities of the many items to be consumed or to be added to society’s productive equipment. Resources are already scarce ie less in quantity. For whom etc to produce are taken by producers without any commanding force but with the market forces of demand and supply. Micro economics studies behavior of individual consumer or producer in a particular situation. It is highly helpful in the formulation of economic policies that will promote the welfare of the masses. Perfect competition is said to exist when there are so many sellers and buyers in the market that no individual seller or buyer is in a position to influence the price of product or factor. It also makes important and useful policy recommendations to regulate monopoly so as to attain economic efficiency or maximum welfare. Till recently, especially before Keynesian Revolution, the body of economics consisted mainly of microeconomics. It also brings to light the fact that the functioning of a completely centrally directed economy with efficiency is impossible. 9] Social welfare Externalities are said to exist when the production or consumption of a commodity affects other people than those who produce, sell or buy it. If it is assumed that resources are optimally allocated or maximum social welfare prevails before the imposition of a tax, then it can be demonstrated by micro-economic analysis that what amount of the damage will be caused to the social welfare. Moreover, as described above, microeconomic theory explains the conditions of efficiency in consumption and production and highlights the factors which are responsible for the departure from the efficiency or economic optimum. Modern economy is so complex that a central planning authority will find it too difficult to get all the information required for the optimum allocation of resources and to give directions to thousands of production units with various peculiar problems of their own so as to ensure efficiency in the use of resources. What are the uses of microeconomics in business decision making? Micro economics uses simple models to understand actual economic phenomenon. Limitations / Disadvantages of Micro economics. 12] Basis of macro economics Further, microeconomic analysis is applied to show the damage done to the social welfare or economic efficiency by the imposition of a tax.
