An individual has an endowment of $100 for consumption now and $0 for consumption later, represented by the point (100, 0). Their 'reservation indifference curve' passes through this point and illustrates all combinations of 'consumption now' and 'consumption later' that would provide them with the exact same level of satisfaction as their initial endowment. Given this, what does it mean if the combination (70, 35) also lies on this specific curve?

Evaluating Preferences for Consumption Over Time

Economic Rationale for Indifference Curve Shape

An individual's initial endowment is $100 for consumption now and $0 for consumption later. The curve representing all combinations of present and future consumption that provide the same level of satisfaction as this initial endowment is described as being downward-sloping and convex.

True or False: Based on the properties of this curve, the individual would strictly prefer a consumption bundle of $80 now and $15 later over their initial endowment.

Evaluating Intertemporal Consumption Preferences

An individual's preferences for consumption now versus consumption later are represented by a standard convex indifference curve. This individual is equally satisfied with their initial endowment of ($100 now, $0 later) as they are with an alternative bundle of ($60 now, $45 later). Based on this information, what is the individual's preference for a third consumption bundle of ($80 now, $22.50 later) relative to their initial endowment?

Interpreting Consumption Trade-offs

An individual's preferences for consumption now versus consumption later can be represented by a 'reservation indifference curve'. This curve shows all combinations of consumption across the two periods that provide the same level of satisfaction as their initial endowment. Match each graphical property of this curve to its underlying economic meaning.

An individual's preferences for consumption now (plotted on the horizontal axis) versus consumption later (plotted on the vertical axis) are represented by a typical convex indifference curve. This curve passes through their initial endowment point of (100 units now, 0 units later). Due to the convex shape of the curve, the rate at which the individual is willing to substitute future consumption for an additional unit of present consumption is at its _________ point when they are at their initial endowment, compared to any other point on the same curve.
