What is macro-economics concerned with?

All of above

The correct answer is Option 4: All of above

Macro-economics deals with a broad range of economic factors related to the performance and behavior of an economy as a whole. This includes analyzing the total output level of goods (Gross Domestic Product or GDP), aggregate demand, and the balance of payments, along with other macroeconomic variables such as inflation, unemployment, and economic growth.

Total output level of goods: This is measured by Gross Domestic Product (GDP), a key metric in macroeconomics that reflects the total value of goods and services produced in an economy.

Aggregate demand: This refers to the total demand for goods and services in an economy. Macroeconomics studies factors influencing aggregate demand, such as consumer spending, government spending, and investment.

Balance of payment deficit: This occurs when a country imports more than it exports, leading to a net outflow of money. Macroeconomics analyzes international trade and factors affecting the balance of payments.

In simpler terms, macroeconomics deals with the big picture of an economy, focusing on how different parts interact and influence the overall performance. It looks at broad aspects like inflation, unemployment, economic growth, and international trade.
