1. Study of aggregates - Macro-economics deals with the study of nations economy as a whole. The scope of Macro Economics is wide. Macroeconomics is concerned with the study of aggregates. It is concerned with concept such as Aggregate Demand, Aggregate Supply, Total Output, General Price Level, National Income, etc.

2. Lumping method - Macro analysis deals with the behavior of aggregates. It uses method of lumping to deal with macro variables such as aggregate supply and demand, national output ,etc. Macroeconomics uses lumping method for the purpose of economic study. Under lumping method we study the general price level, and not prices of individual products.

3. A General Equilibrium Analysis - Analysis deals with entire economy in the context of equilibrium. Macroeconomics is concerned with the behaviour of aggregates and their interdependence. It is a general equilibrium analysis in which everything depends on everything else. For instance, a change in income level may results in change in savings, which in turn may influence investment.

4. Income Analysis - The income theory is a major aspect of macroeconomics theory. A major task of macroeconomics is the determination of national income. Macroeconomics studies the factors determining national income and the causes of the trends in national income

5. Policy-oriented - Analysis helps in formulating suitable economic policies to promote economic growth, generate employment, etc. The study of macroeconomics is highly useful for the formulation and implementation of economic policies of the government. The government is concerned with regulation of aggregates of the economic system such as the general price level, the general level of production, the level of employment, and so on.

6. Dynamic Science - Studies the changes in aggregate economic variables and analyses dynamic nature of economy.

7. Based on Interdependence - Analysis takes accounts of interdependence between aggregate economic variables like how changes in one variable will make changes in another. It is a General Equilibrium approach in which everything depends on everything else and therefore there is an element of inter-dependency among the Macroeconomics variables.

8. Overall view of the economy: - the study of macroeconomics gives an overall view of the economy. It interlinks various aggregates so as to show the inter-relationships between them.it tend to provide a more realistic view of the overall economy.
