Disposable income is equal to :

Question

Accepted Answer

Disposable income is a key concept in economics that refers to the amount of money individuals have available for spending and saving after accounting for personal taxes. Let's delve into why Option 2, "Personal income – Personal taxes," is the correct answer and why the other options are incorrect.

### Explanation for Option 2:

**Disposable Income = Personal Income – Personal Taxes**

1. **Definition**: Disposable income is the net income available to an individual or household after all personal taxes have been deducted from their total personal income. It represents the amount of money that can be used for consumption, saving, or investing.

2. **Economic Relevance**: This measure is crucial for understanding consumer behavior, as it directly influences spending and saving patterns. Higher disposable income typically leads to increased consumer spending, which can drive economic growth.

3. **Logical Reasoning**: Since disposable income is what remains after taxes, it logically follows that subtracting personal taxes from personal income gives the correct measure of disposable income. This aligns with standard economic definitions and practices.

### Explanation for Why Other Options Are Incorrect:

1. **Option 1: Personal income – Saving**
   - **Incorrect**: This option suggests that disposable income is calculated by subtracting savings from personal income. However, savings are a part of what individuals do with their disposable income, not a deduction to calculate it. Disposable income is what is available before deciding how much to save or spend.

2. **Option 3: GNP – Saving**
   - **Incorrect**: Gross National Product (GNP) is a measure of a country's economic output and is not directly related to an individual's disposable income. Subtracting savings from GNP does not yield disposable income, as GNP includes all production within a nation, not just personal income.

3. **Option 4: Consumption – Saving**
   - **Incorrect**: This option implies that disposable income is the difference between consumption and saving. However, disposable income is what is available to be consumed or saved, not the result of subtracting one from the other. Consumption and saving are outcomes of how disposable income is utilized.

In conclusion, Option 2 is the correct answer because it accurately reflects the definition and calculation of disposable income as understood in economic terms. It is the net income available after personal taxes, which is essential for understanding consumer behavior and economic activity.
