  • Figure 3.5: Karim's Indifference Curves

Activity: Constructing an Indifference Curve

A systematic method for constructing an indifference curve involves a sequential questioning process to identify bundles of goods that yield the same utility. Starting with an initial bundle, like point A (15 hours of free time, €540), the individual is asked how much of one good (consumption) they would trade for an additional unit of the other (free time). For instance, if Karim is willing to sacrifice €94 for one extra hour of free time, it establishes that he is indifferent between point A and point E (16 hours, €446). This process is repeated for subsequent points (E to F, F to G, etc.) to map out a series of equally satisfying combinations. These points are then plotted and connected to form the curve.

  • An individual's choices between daily free time and consumption (€) are represented on a graph. Two specific combinations, Point A (15 hours of free time, €540 consumption) and Point D (20 hours of free time, €240 consumption), are known to provide the individual with the exact same level of satisfaction. Given this information, which of the following statements accurately describes the individual's preference for a third combination, Point X (15 hours of free time, €600 consumption)?

  • An individual is indifferent between two combinations of daily free time and consumption: Bundle A (15 hours, €540) and Bundle D (20 hours, €240). This implies that the rate of exchange is constant, meaning the individual is always willing to give up €60 of consumption for one additional hour of free time to remain equally satisfied.

  • Interpreting the Shape of an Indifference Curve

  • A diagram shows that an individual is equally satisfied with two different combinations of daily free time and consumption: combination A (15 hours of free time, €540 consumption) and combination D (20 hours of free time, €240 consumption). Based only on the comparison between these two points, what is the average amount of consumption this individual is willing to sacrifice to gain one additional hour of free time?

  • A diagram shows that an individual is equally satisfied with two different combinations of daily free time and consumption: combination A (15 hours of free time, €540 consumption) and combination D (20 hours of free time, €240 consumption). Based only on the comparison between these two points, what is the average amount of consumption this individual is willing to sacrifice to gain one additional hour of free time?

  • An individual's preferences for daily free time and consumption are being studied. It is found that they are equally satisfied with either combination A (15 hours of free time, €540 consumption) or combination D (20 hours of free time, €240 consumption). Separately, it is determined that they are also equally satisfied with either combination B (13 hours of free time, €540 consumption) or combination Z (16 hours of free time, €500 consumption).

    Based on the standard properties of how such preferences are represented graphically, which of the following statements must be true?

  • An individual's preferences show that they are equally satisfied with two different daily combinations of free time and consumption: Combination A (15 hours of free time, €540 consumption) and Combination D (20 hours of free time, €240 consumption). Consider a third combination, F, which provides the same level of satisfaction as A and D, but with 16 hours of free time. Based on the typical shape of such preference representations, which of the following is the most plausible level of consumption for Combination F?

  • Comparing Preferences for Free Time

  • An individual is equally satisfied with two combinations of daily free time and consumption: Combination A (15 hours, €540) and Combination D (20 hours, €240). Their preferences are represented by a standard convex curve (bowed towards the origin). Which statement best describes the individual's willingness to trade consumption for one additional hour of free time when they are at Combination A?

  • A consumer is currently consuming a bundle of 8 cups of coffee and 12 pastries per month. To map out a curve representing bundles of equal satisfaction, the consumer is asked how many pastries they would be willing to trade for one additional cup of coffee. The consumer states they are willing to give up 3 pastries. Based on this information, which of the following bundles would represent another point on the same curve?

  • Analyzing Consumer Preferences for Curve Construction

  • When using a sequential questioning process to map out the points on a single indifference curve, the amount of one good a person is willing to sacrifice for one additional unit of the other good will remain constant at each step.

  • An economist is identifying a series of combinations of 'Good X' and 'Good Y' that provide a consumer with the same level of satisfaction. Starting with Bundle A (10 units of X, 50 units of Y), the economist determines the following sequence of equally preferred bundles by repeatedly asking how much Y the consumer would trade for one more unit of X:

    • From A to B: The consumer trades 5 units of Y for 1 unit of X, resulting in Bundle B (11X, 45Y).
    • From B to C: The consumer trades 4 units of Y for 1 unit of X, resulting in Bundle C (12X, 41Y).
    • From C to D: The consumer trades 3 units of Y for 1 unit of X, resulting in Bundle D (13X, 38Y). Which of the following proposed bundles for the next point (Bundle E, with 14 units of X) would be inconsistent with the typical shape of a curve representing these preferences, which assumes a diminishing willingness to trade?
