Activity: Decomposing the Total Effect of a Wage Rise into Income and Substitution Effects
The total effect of a wage increase on an individual's choice, such as the move from an initial point A to a new optimal point D, can be analytically broken down into two distinct components: the income effect and the substitution effect. This decomposition is illustrated graphically by introducing a hypothetical budget constraint that is parallel to the original one but tangent to the final indifference curve at a point C. This isolates the income effect (the move from A to C) from the substitution effect (the move from C to D).

Analyzing a Change in Work Hours
A worker receives a significant hourly wage increase. They reflect on the change with two conflicting ideas:
- Idea A: "Since each hour of my free time now costs me more in lost earnings, I feel motivated to work additional hours."
- Idea B: "Since I can reach my weekly income goal faster, I feel I can afford to take more time off for leisure."
Which option correctly identifies the economic effects described in these ideas?
Consider an individual who experiences a wage increase. If this person chooses to work fewer hours, it is logically necessary that the income effect of the wage increase is greater in magnitude than the substitution effect for that individual.
A worker's hourly wage increases. Match each line of reasoning or observed outcome with the economic principle it primarily represents.
Evaluating a Labor Supply Decision
When an individual's wage increases, if the effect that makes leisure feel more affordable is stronger than the effect that makes leisure more costly in terms of lost earnings, the total quantity of labor supplied by that individual will ________.

Analyzing a Freelancer's Work-Life Decision
An economist observes that after a company-wide wage increase, employees responded differently, with some choosing to work more hours and others fewer. To explain any individual employee's choice, the economist must logically disentangle the two conflicting effects of the wage rise. Arrange the following analytical steps in the correct logical sequence that breaks down this decision-making process.

Activity: Four-Step Method for Decomposing the Effect of a Wage Rise
An individual experiences a significant increase in their hourly wage. After this wage change, they are observed to be working fewer hours per week than before. Based on this outcome, what can be concluded about the income and substitution effects on their demand for leisure?
An economist is graphically decomposing the total effect of a wage increase on an individual's choice between leisure and consumption. The analysis involves an initial optimal point (A), a final optimal point (D), and a hypothetical intermediate point (C). Arrange the following steps into the correct logical sequence for performing this decomposition using the Hicksian method.
Analyzing a Worker's Response to a Wage Increase
An individual's optimal choice of leisure and consumption changes in response to a wage increase. The graphical analysis of this change involves an initial optimal point (A), a final optimal point (D), and a hypothetical intermediate point (C). Point C lies on the original indifference curve but is tangent to a hypothetical budget line that has the same slope as the new, final budget line. Match each economic effect to the corresponding movement between these points.
In the graphical analysis of a wage increase, a hypothetical point 'C' is used to separate the total change in an individual's choice into two components. To correctly isolate the pure income effect as the first step of the decomposition, this point 'C' must represent a combination of goods and leisure that lies on the individual's original indifference curve.
Explaining the Decomposition of a Wage Change
In the analysis of a worker's response to a wage change, the portion of the total change in hours worked that is attributable to the change in the relative price of leisure, while keeping the worker's level of satisfaction or utility constant, is called the ________ effect.
Explaining the Substitution Effect
An analyst is graphically decomposing the total effect of a wage increase on a worker's choice between consumption and leisure. The analysis moves from an initial optimal point (A) to a final optimal point (D). To do this, a hypothetical intermediate point (C) is constructed. If the goal is to define the substitution effect as the movement from point C to point D (a movement along the final indifference curve), which of the following correctly describes the necessary properties of point C and its associated hypothetical budget line?
