Economicss is the survey of how limitless wants can be satisfied with scarce resorts. Economicss is a subdivision of societal scientific discipline that trades with production ingestion and transportation of wealth. The term economic sciences is derived from an ancient Grecian word “ oikonomia ” which means direction of family. Oikos means house and nomos means jurisprudence or usage that means regulations of house clasp. 1776 is considered the twelvemonth of Economics as a separate field of survey, when The Wealth of Nations was published by Adam Smith, a Scots societal philosopher. There are two wide subfields of economic sciences micro economic sciences and macro economic sciences. Micro means little and microeconomics trades with the smaller parts of economic sciences such as economic status of an person or a houses, demand and supply of any single houses or family, monetary value of a specific merchandises etc. Macro means large or big, and trades with big portion of economic sciences such as aggregative demand and supply, rising prices, involvement rates, economic growing and unemployment etc. If income of a family is the capable affair of microeconomics so national income will be the capable affair of Macroeconomics. Though both Microeconomics and Macroeconomics are the parts of economic sciences they have some differences and they hay related to each other every bit good.

Literature reappraisal and Discussion:

Micro economic sciences is the survey of single unites. It is a subdivision of economic sciences that study how family determinations are made to apportion scarce resource. On the other manus macro economic sciences survey of economic system as a whole. It is a survey of economic sums. There are many differences between these two parts of economic sciences. They differ in their Nature, Scope, Purpose, Need objective, Instrument and Analysis. “ Microeconomics is concerned with the cosmopolitan job of scarceness while trades with the economic system as a whole ” ( A. T. Clement and H. Keith, 2008, pp 18 ) . Microeconomics is a survey of scarceness and pick, which deals with the determination doing jobs of what to bring forth, how to bring forth, for whom to bring forth and who will take that what to bring forth concern houses and families and the policies taken by the authorities for these unites. While single houses and house clasp determinations are non the affair of concern of Macroeconomics. It solves the jobs of national income, unemployment, end product, input, export-import, GDP, rising prices, authorities budget shortages etc.

Micro economic sciences trades with normal demand and supply, demand is the privation of holding some thing, ability to pay for it and hold the willingness to pay for it and supply is the measure of a merchandise that a manufacturer wants to sell at a given monetary value. On the other manus macro economic sciences trades with Aggregate Demand and Aggregate supply

The totalA amountA of goods and services demandedA in the states economic system at a given overall monetary value degree within a given clip period.A Aggregate demand in macroeconomics is the demand for the gross domestic merchandise ( GDP ) of a state, and Aggregate Demand is represented the expression:

Aggregate Demand ( AD ) = C + I + G ( X-M )

In this expression ‘C ‘ bases for Consumers ‘ outgos ; ‘I ‘ is Investment disbursement by houses on capital goods, and ‘G ‘ represents Government outgos on public goods and services. ‘X ‘ bases for Exports of goods and services and ‘M ‘ is Imports of goods and services. Aggregate demand is known as entire outgo or entire input. Aggregate supply is the entire supply ( goods and service ) produced in an economic system in a given period of clip and in a given overall monetary value degree.

“ In microeconomics, the equilibrium occurs when the measure demanded peers the measure supplied. In macroeconomics, on the other manus, equilibrium occurs when the aggregative demand peers aggregate supply ” ( Abhijit Naik, 2010 ) equilibrium in macro economic sciences can be for short tally or long tally but in micro economic sciences it is merely one general equilibrium.

Equilibrium in Micro economic sciences

In short tally AD is aggregated demand, SAS represents aggregated supply, P is monetary value and A and B are two equilibrium.

In long tally equilibrium every house will gain normal net income, and that is, nothing net income, monetary value ( P ) is equal to fringy cost ( MC ) , means P = MC, monetary value ( P ) is equal to the lower limit of short tally norm cost ( SRAC ) , P = SRAC. This entails zero economic net income, monetary value ( P ) is equal to the lower limit long tally norm cost ( LRAC = ATC ) , P = minimal LRAC.

5. Puting it all together:

P = MC = min SRAC = min LRAC

“ The bottom line is that microeconomics takes a bottoms-up attack to analysing the economic system while macroeconomics takes a top-down attack ” . (, 19. 04.2011 )

Micro economic sciences and Macro economic sciences is non wholly different from each other, they are non reciprocally sole. Micro economic sciences and Macro economic sciences reflects each other they are besides complementary to each other. Actually Macro-economics has a foundation in Micro-economics and Micro-economics besides has a foundation in Macro-economics. That means they are frailty versa. There are many similarities in these two subdivisions of economic sciences the first one is of the subdivisions trades with supply and demand conditions, macroeconomics trades with aggregative supply and demand but it follows the same jurisprudence of demand which is if all other factors remain changeless so measure demanded will diminish with the addition of monetary value degree. It besides follows the jurisprudence of supply. Law of supply says that if all other factors remain changeless so measure supplied will increase with the addition of monetary value degree. Both micro and macro economic sciences have the focal point on the inducements and chance costs means both of the subdivisions attempts to accomplish the stakes fit giving the following best options, aggregating up behaviour, both Micro economic sciences and Macro economic sciences retains concentrate on making the equilibrium conditions and when monetary value alterations in both instance the demand and supply displacement parallel. In both subdivisions there are excess and deficit. There are many other similarities and unsimilarities between these two subdivisions.


Despite of holding some unsimilarities Micro economic sciences and Macro economic sciences both are of import and need to be understood to hold a full cognition of economic sciences. To understand national economic system is of import but it is besides necessary to understand the family economic system and the house ‘s economic system to put a states economic policy and have the same importance. Because aggregative family economic system and the house ‘s economic system is the macroeconomics but this two subdivisions should hold proper combination in the policy so that they can back up each other. We should cognize the differences but should non give our full focal point on the differences. We should hold combined cognition on these two subdivisions of economic sciences.
