Question

Write the names of two stock variables and two flow variables.

Hint:

Stock variables represent a snapshot at a given point in time, while flow variables are measured over a specific time period.

Answer 1

In economics, variables are classified into two categories: stock variables and flow variables. Below are the definitions and examples of each:
Step 1: Stock Variables.
Stock variables are quantities that are measured at a specific point in time and represent a snapshot of the economy. These variables do not change over time but reflect the status of an economic entity at a given moment. Examples include:
- National Debt: The total amount of money a government owes to creditors at a particular time.
- Capital Stock: The total value of machinery, buildings, and other physical assets in an economy at a given point in time.

Step 2: Flow Variables.
Flow variables are quantities that are measured over a period of time, representing the rate at which something is occurring. These variables change continuously over time. Examples include:
- Income: The total earnings of an individual or a household over a period of time, such as monthly or yearly income.
- Expenditure: The total spending of individuals, businesses, or governments over a period of time.
