Angela's Indifference on Indifference Curve IC3

Quasi-linear Preferences

Convexity of Angela's Preferences

An individual's preferences for a consumption good (grain) and free time are represented by indifference curves that are downward-sloping and become flatter as the amount of free time (plotted on the horizontal axis) increases. What does this specific shape imply about the trade-off this person is willing to make?

An individual's preferences for grain and free time are such that the slope of their indifference curves at any point depends only on the amount of free time at that point. True or False: This individual's willingness to sacrifice grain for an additional hour of free time is higher when they have a large amount of grain compared to when they have a small amount of grain, assuming the amount of free time is the same in both situations.

Explaining Preferences for Goods and Leisure

Analyzing a Farmer's Choices

An economic model represents an individual's choices between consuming a good (grain) and enjoying leisure (free time) using a graph. The horizontal axis represents hours of free time, and the vertical axis represents bushels of grain. Match each graphical feature to its correct economic interpretation.

Interpreting Preferences and Trade-offs

An individual's preferences for free time and grain are represented by an indifference curve. At Point A, with 16 hours of free time, the individual is willing to give up 3 bushels of grain to get one more hour of free time. At Point B, on the same indifference curve but with 20 hours of free time, they are only willing to give up 1 bushel of grain for an additional hour of free time. What does this change from Point A to Point B demonstrate about the individual's preferences?

An individual is offered payment to work extra hours. When they have 18 hours of free time left in a day, they are willing to give up one hour of free time for $20. When they only have 10 hours of free time left, they require $50 to give up one more hour of free time. Based on this information, which statement provides the most accurate economic interpretation of this individual's preferences?

An individual's preferences for a consumption good (measured on the vertical axis) and free time (measured on the horizontal axis) are such that for any given amount of free time, the slope of their indifference curve is identical, regardless of their level of consumption. If this individual receives an unexpected cash inheritance that they do not have to work for, how will this affect the amount of the consumption good they would require as compensation to willingly give up one more hour of free time?

An individual's preferences for a consumption good and free time are represented by indifference curves that are convex (bowed in toward the origin). This shape implies that the individual places a higher value on an hour of free time when they have very little free time remaining compared to when they have an abundance of it.
