An individual's indifference curve, which illustrates their trade-offs between consumption today and consumption in the future, has a slope of -1.05 at their current consumption level. Based on this information, what is this individual's discount rate (ρ)?

An individual who is perfectly patient, valuing an extra unit of consumption in the future exactly the same as an extra unit of consumption today, would have an indifference curve with a slope of -1 at their current point of consumption.

Calculating Indifference Curve Slope from Discount Rate

Calculating a Personal Discount Rate

An individual's trade-off between consumption today and consumption in the future can be visualized with a curve. The slope of this curve at a given point indicates the individual's impatience. The personal discount rate (ρ) is calculated from this slope. Match each given slope to the correct discount rate (ρ) that would be calculated from it.

An individual's personal discount rate (ρ) is calculated by taking the absolute value of the slope of their indifference curve for present and future consumption and subtracting ____.

Comparing Patience Levels Using Indifference Curves

An economist is studying the saving habits of two individuals, Sam and Maria. The slope of Sam's indifference curve, which represents his trade-offs between consumption today and consumption in the future, is -1.15. The slope of Maria's indifference curve for the same trade-off is -1.04. Based on this information, which of the following statements is correct?

An economist wants to determine an individual's personal discount rate (ρ) by examining their preferences for consumption now versus in the future. The economist has identified the slope of the individual's indifference curve at their current consumption bundle. Arrange the following steps in the correct order to calculate the discount rate.

An economist observes that at their current consumption level, an individual is willing to trade 1.08 units of future consumption for exactly 1 unit of present consumption, remaining equally satisfied. The economist concludes, "This individual has a low preference for immediate gratification and is likely a patient long-term planner." Based on the formula for the personal discount rate (ρ), evaluate the economist's conclusion.
