The Overall Effect as the Sum of Income and Substitution Effects

An individual's choice between daily free time and consumption is depicted in a standard graphical model. The horizontal axis measures hours of free time, and the vertical axis measures consumption ($). Initially, the individual's budget constraint is BC1, and their optimal choice is at point A on indifference curve IC1. Following a wage increase, the budget constraint becomes steeper, represented by BC2, and the new optimal choice is at point D on a higher indifference curve, IC2. A hypothetical point, B, also lies on the original indifference curve IC1. Which of the following movements represents the total change in the hours of free time chosen as a result of the wage increase?

In a standard model of choice between consumption and free time, if a wage increase causes an individual's new optimal consumption-leisure bundle to be located to the left of their original bundle on the horizontal (free time) axis, the overall effect of the wage change is an increase in hours worked.

Calculating the Overall Effect of a Wage Change

Defining the Overall Effect of a Wage Change

Consider a model where an individual chooses between daily consumption (vertical axis) and hours of free time (horizontal axis). An individual's initial optimal choice is at point A, where they enjoy 18 hours of free time. After a significant increase in their hourly wage, their new optimal choice is at point D, where they enjoy 16 hours of free time. Based on the movement from point A to point D, what can be concluded about the total effect of the wage increase on this individual's labor supply?

Evaluating the Impact of a Wage Increase on Labor Supply

Interpreting the Overall Effect of a Wage Change Graphically

An individual chooses between daily consumption (vertical axis) and hours of free time (horizontal axis, with a maximum of 24 hours). Initially, they choose to work 6 hours per day. After their hourly wage increases, they adjust their schedule and now work 8 hours per day. Which of the following descriptions correctly represents the overall effect of this wage change on their choice of free time?

Analyzing a Worker's Response to a Wage Increase

A consultant initially works 40 hours per week, leaving 72 hours for free time. After receiving a significant raise in their hourly rate, they adjust their schedule and now work 45 hours per week. Which of the following statements accurately describes the total effect of this wage change on their choice of free time?
