Original, Final, and Hypothetical Budget Constraints in Figure 3.13b
The analysis of income and substitution effects in Figure 3.13b involves a comparison of three budget constraints. The 'original' constraint shows the initial trade-off. The 'final' constraint is steeper, reflecting the higher opportunity cost of free time from a wage increase. The 'hypothetical' constraint is an analytical tool with the same slope as the original line but shifted to be tangent to the final indifference curve. This design distinguishes the impact of the change in purchasing power (income effect) from the change in the relative cost of leisure (substitution effect).

In an economic model analyzing an individual's response to a wage increase, a graph shows three budget constraints: an 'original', a 'final', and a 'hypothetical'. The hypothetical budget constraint is constructed to have the same slope as the final budget constraint but is tangent to the individual's original indifference curve. What is the primary analytical purpose of this hypothetical budget constraint?
Analyzing Income and Substitution Effects on Labor Supply
An economic model illustrates an individual's response to a wage increase using three points of choice between consumption and free time:
- Point A: The initial optimal choice on the original budget constraint and original indifference curve.
- Point C: The final optimal choice after the wage increase, located on the new, steeper budget constraint and a higher indifference curve.
- Point B: A hypothetical choice point on the original indifference curve where a hypothetical budget constraint (with the same steepness as the new, final one) is tangent.
Match each movement between these points to the economic effect it isolates.
Constructing the Hypothetical Budget Constraint
When analyzing the effects of a wage increase on an individual's choice between consumption and free time, the 'hypothetical' budget constraint used for decomposition is constructed to be parallel to the original budget constraint in order to isolate the substitution effect.
Interpreting Labor-Leisure Choice
An economist wants to isolate the income and substitution effects resulting from a wage increase on an individual's choice between leisure and consumption. Arrange the following analytical components in the correct logical sequence used to perform this decomposition.
Evaluating a Method for Decomposing Wage Effects
An economist analyzes an individual's choice between consumption and free time in response to a wage increase. The analysis uses three distinct points of choice:
- An initial optimal choice on the original budget constraint.
- A final optimal choice on the new, steeper budget constraint.
- A hypothetical choice on the original indifference curve, located where a budget line with the new, higher wage would be tangent.
What economic principle is isolated by the change observed when moving from the hypothetical choice (Point 3) to the final optimal choice (Point 2)?
