3. What is economics? Economics comes from the Greek word Oikonomia. Oikos(means a household) + Nomos(means management). So, it means household management.

4. Adam Smith (1723 -1790), the founder of economics, described it as a body of knowledge which relates to wealth. Accordingly to him if a nation has larger amount of wealth, it can help in achieving its betterment. He defined economics as: “The study of nature and causes of generating of wealth of a nation”.

5. L. Robbins defined as-“Economics is the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses.”

6. This definition base on three basic characteristics of human life: 1.Unlimited wants (ends) 2.Limited resources (scarce means) 3.Alternative uses of resources

7. Finally we can say that Economics is that branch of science, which deals with production, consumption and distribution of wealth.

8. Definition of Macro Economics The term 'Macro' is derived from the Greek word 'Uakpo' which means large. Macro economics looks at the economy as a whole. It examines the factors that determine national output and its growth overtime.

9. According to R. G. D. Allen: "The term macro economics applies to the study of relations between broad economic aggregates such as total employment, income and production".

10. In the words of Edward Shapiro: "The major task of macro economics is the explanation of what determines the economy's aggregate output of goods and services. It deals with the functioning of the economy as a whole".

11. Professor K. E. Boudling is of the view that: "Macro economics is that part of economics which studies the overall averages and aggregates of the economic system. It does not deal with individual incomes but with the national income, not with individual prices but with the price level, not with individual output, but with national output".

12. Importance/Issues/Scope of Macro Economics (i) It helps in understanding the determination of income and employment (ii) Determination of general level of prices. iii) Economic growth (iv Macro economics and business cycles.

13. Importance/Issues/Scope of Macro Economics (v) International trade (vi) Income shares from the national income. (vii) Unemployment. (viii) Macroeconomic policies (ix) Global economic system.

14. Limitations/Exceptions of Macro Economics (i) The macro economies ignore the welfare of the individual. For instance, if national saving is increased at the cost of individual welfare, it is not considered a wise policy.

15. (ii) The macro economics analysis regards aggregates as homogeneous but does not look into its internal composition. For instance, if the wages of the clerks fail and the wages of the teachers rise, the average wage may remain the same.

16. (iii) It is not necessary that all aggregate variables are important. For instance, national income is the total of individual incomes. If national income in the country goes up, it is not necessary that the income of all the individuals in the country will also rise. There is a possibility that the rise in national income may be due to the increase in the incomes of a few rich families of the country.

17. (iv)The macroeconomic models are designed mostly to suit the developed countries of the world. The developing countries face different economic realities, so they do not benefit much from them.
