Macro economics is the study and analysis of economic system as a whole

Macro economics is called income theory. It explains the level of total production and why the level rises and fall.

In Macro we study how the aggregates and the averages of the economy as whole is determined and what causes fluctuation in them.

In macro we study the general price level in country.

In macro we study the aggregate demand of the entire country.

Here we study the national income of the country.

It shows how an economy grows. It gives bird eye view of economic world.

Individual ignored altogether. It is individual welfare, which is the main aim of economics. Increasing national saving at the expense of individual welfare is not a wise policy.

It over looks individual differences for instance, the general price level may be stable but the prices of food grains may have gone spelling ruin to the poor.

The economy as a whole is more important for formulation of useful economic policies for the nation.
