4. Discuss the subject matter of economics.
Answer
The subject matter of economics has been studied under two broad branches: Microeconomics and Macroeconomics.
In microeconomics, we study the behaviour of individual economic agents in the markets for different goods and services and try to figure out how prices and quantities of goods and services are determined through the interaction of individuals in these markets.
In macroeconomics, we try to get an understanding of the economy as a whole by focusing our attention on aggregate measures such as total output, employment and aggregate price level. We are interested in finding how the levels of these aggregate measures are determined and how the levels of these aggregate measures change over time.
