Figure 9.5: Julia's Indifference Curves and Situational Impatience
Figure 9.5 visually represents Julia's preferences with multiple indifference curves. Her reservation indifference curve passes through her endowment at point A ($0 now, $100 later), where its steepness indicates high situational impatience. The figure also shows a hypothetical scenario at point B ($100 now, $0 later), where her indifference curve would be very flat, signifying low impatience due to her desire to smooth consumption. This contrast highlights how impatience is situational. Additionally, the figure allows for utility comparisons, as point B lies on a higher, more preferred indifference curve than point A, and it helps quantify intrinsic impatience by showing indifference between point A and a point like B' (approx. $50 now).

A subsistence farmer has just planted their annual crop. They currently have no goods to consume but are guaranteed a large harvest in six months. At their present endowment point (zero consumption now, substantial consumption later), which of the following best describes the shape of their reservation indifference curve and their resulting behavior?
Interpreting Consumer Choice at the Endowment Point
Analyzing Impatience from Consumption Patterns
Consider an individual whose entire endowment consists of consumption available in the future, with zero consumption available in the present. A statement claims their reservation indifference curve at this endowment point is relatively flat, signifying they are only willing to sacrifice a small amount of future consumption to gain one unit of present consumption. Is this statement correct?
An individual's willingness to trade consumption between the present and the future can be visualized by the steepness of their indifference curve at their current consumption point (their endowment). A steeper curve indicates more impatience (a higher willingness to give up future consumption for present consumption). Match each endowment scenario with the description that best reflects the individual's level of impatience and the corresponding shape of their indifference curve at that point.
Evaluating Aid Programs Using Intertemporal Choice
An individual whose endowment consists of zero consumption in the present and a guaranteed amount of consumption in the future will have a very steep reservation indifference curve at that point. This steepness signifies a high degree of situational impatience, meaning they are willing to give up a ____ amount of future consumption to obtain even a small increase in present consumption.
Analyzing an Intertemporal Loan Offer
An individual's 'situational impatience' reflects their eagerness to consume goods now rather than later, which is heavily influenced by their current endowment (their combination of present and future consumption). Impatience is typically highest when an individual has very little for present consumption. Consider three individuals with different endowments. Arrange them in order from MOST impatient to LEAST impatient.
An individual's current financial situation consists of having no money for consumption today, but a guaranteed income of $200 available for consumption in one year. At this specific point, the slope of the indifference curve that represents their minimum acceptable level of well-being is -5. What does this specific slope value indicate about the individual's preferences?
