Achievement of Full Employment
The foremost and the basic objective of the study of macro economics is to understand the ways by which full employment level can be achieved or alternatively the problem of unemployment is to be tackled. The higher the level of employment is, the higher will be the gross domestic product (G.D.P) or national output of a country. At higher income level, the consumption of the people would go up due to which their standard of living will rise. This will result in the prosperity of the people. Thus, in the third world countries in particular, the economic policies should be devised in such a way that more than 95% of the labor force can be provided with jobs.

Achievement of Price Stability or Control of Inflation
When the rate of increase in money supply is larger than the growth rate of output, general price level in the country will go up and this tendency may continue for years. The persistent rise in the general price is termed as inflation. Whenever there is an inflationary spiral in a country, it renders fixed income or salaried group to be poorer than before. Creditors remain at loss and they tend to compensate it by increasing the rate of interest on loans. In macro sense, aggregate investment, income and employment level fall resulting thereby a sharp inequality of income distribution. Thus, in this situation, government is required to devise sound monetary and fiscal policies to bring the rate of inflation at its lowest ebb so as to ensure economic growth and development.

Achievement of Balance of Payments Equilibrium
When the import payments of a country are larger that its export receipts, its balance of payments falls in deficit which ultimately brings a sharp reduction in its foreign exchange reserves. Thus, the country is forced to seek loans from foreign countries. External value of the currency is depreciated which as a consequence brings waves of inflationary spiral in the country. In this situation, what is required is that government should devise sound commercial policies so that demand for exports rises and that of imports falls and thereby the adverse balance of payments situation is rectified.

Achievement of Growth and Development
When the growth rate of real G.N.P of a country is consistently larger than the growth rate of population, the real per capita income of the people rises over a long period of time which is termed as growth and development in the economy of a country. This brings in prosperity and a rise in the standard of living of the people. In macro economics, we study the policies which lead to the most appropriate exploitation of natural, human and capital resources of a country to increase its production level. This process is initiated to ensure rapid growth and development in the country.
