Therefore, macroeconomics is also known as aggregative economics.
Macroeconomics can be defined as the study of the behavior and performance of the economy as a whole. It also explains how the equilibrium levels of national income and employment are determined. Therefore, macroeconomics is also known as the 'Theory of Income and Employment'. The major variables of macroeconomics are national income, national output, total consumption, total expenditure, total saving, total investment, etc.

2. Probable Explain the concept of closed and open economies with their characteristics.
Closed Economy
An economy that does not participate in international trade is called a closed economy. In other words, a closed economy trades only within its own border and does not get involved in the import and export of goods and services. Such a type of economy is completely self-sufficient and often backward or underdeveloped because such an economy has to depend on the raw materials, skills, and technology, which are available within the country. All the countries of the world are involved in external trade, i.e. export and import. Self-sufficiency is not possible in the modern world.
Features of Closed Economy
The features of the closed economy are as follows:
- A closed economy has no economic relation with the rest of the world.
- It neither imports goods and services from foreign countries nor exports goods and services to foreign countries.
- It neither borrows from the foreign countries nor lends to the foreign countries.
- It neither takes foreign aid nor gives aid to other countries.
- A citizen of a closed economy can not go to other countries to work and foreigners are also not allowed to work in the domestic territory of the closed economy.
- Since income received from abroad and income paid to foreigners are zero, the GDP and GNP of the closed economy are equal.
Open Economy
An economy that participates in international trade is called an open economy. In other words, an open economy trades not only within its own border but also involves in export and import of goods and services. Such type of economy is also known as the four-sector economy because this economy consists of four sectors: household sector, business sector, government sector, and foreign sector. In the modern era, all economies of the other. They import and export raw materials, labor, technology, capital, etc. The world is open to economies. These economies are interdependent with each No country in the world can be self-dependent. This is a realistic or actual situation of the modern world. The degree of openness of the economies is increasing due to the increasing globalization of the world.
Features of Open Economy
The features of the open economy are as follows:
- An open economy has economic relations with the rest of the world.
- An open economy imports and exports goods and services or has trade relations with other countries of the world.
- An open economy borrows from other countries and also lends to other countries.
- A citizen of an open country can go to the other countries to work and foreigners are also allowed to work in the domestic territory of the open economy.
- It sends gifts and remittances to the foreigners and receives the same from them too.
- Since citizens of the open economies receive income from abroad and pay income to foreigners, GDP and GNP are different.

In other words, macroeconomic variables are indicators that show the situation and trends of the whole economy. There are various macroeconomic variables like aggregate demand and supply, national income, GDP, GNP, economic growth rate, price level (rate of inflation and deflation), total investment, total saving, total consumption, trade balance, demand for and supply of money, level of employment and unemployment, total labor force, total export, total import, government budget, exchange rate, etc.
Major Macroeconomic Variables
The major macroeconomic variables are as follows:
