Ethical Critique of Nordhaus's Use of Intrinsic Impatience
Critics of William Nordhaus's methodology contend that the psychological tendency of individuals to prefer their own present consumption over their own future consumption—known as intrinsic impatience—is not an appropriate ethical justification for discounting the welfare and ambitions of future generations.

Ethical Critique of Nordhaus's Use of Intrinsic Impatience
In his economic models, William Nordhaus incorporated a component into his discount rate to account for 'intrinsic impatience.' He quantified this by observing market interest rates. Which statement best analyzes the reasoning behind this specific methodological choice?
Underlying Assumption in Nordhaus's Method
William Nordhaus justified the inclusion of a rate for 'intrinsic impatience' in his discount model by arguing that prevailing market interest rates represent a direct, observable measure of society's collective ethical judgment on the value of future generations.
Rationale for Nordhaus's Method
Applying a Market-Based Approach to Time Preference
Evaluating Market-Based Time Preference for Long-Term Policy
An economist proposes using real market interest rates as a direct measure to help determine a discount rate for long-term public projects. What is the core assumption this economist is making about the meaning of market interest rates in this context?
To quantify the preference for present over future consumption, a concept he termed 'intrinsic impatience,' William Nordhaus used observable __________ as a direct measure, interpreting them as the slope of the feasible set for consumption choices.
Reasoning Behind Market-Based Time Preference
An economist proposes quantifying the societal preference for present over future consumption by observing market behavior. Match each component of this economist's methodology to its correct description.
Evaluating Market-Based Time Preference
An economist proposes that the most accurate way to measure a society's collective preference for consuming goods now versus in the future is to examine real-world market interest rates. The logic is that these rates reflect the price people are willing to pay to shift consumption between different points in time. Which statement best analyzes the fundamental assumption underlying this methodological approach?
An economist observes that in a stable economy, the average real interest rate on long-term government bonds is 4%. Based on a methodology that interprets this market rate as a reflection of society's time preference, the economist concludes that the population has a relatively low degree of 'intrinsic impatience' (i.e., they do not strongly favor present consumption over future consumption).
An economist proposes using current market interest rates to determine the value of 'pure time preference' within a discount rate for long-term public projects. The rationale is that these rates reveal how individuals in the market trade off their own present consumption against their own future consumption. Which of the following statements presents the most fundamental challenge to this methodology when applied to projects with multi-generational impacts?
Selecting Data for a Time Preference Calculation
An economist proposes a method for determining the 'pure rate of time preference' for use in a discount rate. The method involves observing real-world financial data and interpreting it as a reflection of human behavior. Match each component of this methodological argument to its corresponding description.
In a methodology that quantifies a society's time preference by observing real-world financial data, the market interest rate is interpreted as a direct measure of the public's collective ____, reflecting how much they value their own present consumption over their own future consumption.
Interpreting Market Interest Rates as Time Preference
A particular economic methodology for determining a component of a discount rate is based on observing real-world financial markets. Arrange the following steps to reflect the logical progression of this methodology, from initial observation to its final application.
Evaluating the Justification for Intergenerational Discounting

The Market for Votes
An economic model for long-term climate policy incorporates a 'discount rate' to weigh the welfare of future generations against present-day costs. A component of this rate is justified by the observation that individuals generally prefer immediate gratification over future rewards, a tendency known as 'intrinsic impatience'. Which of the following statements presents the most significant ethical objection to using this individual tendency as a basis for the policy's discount rate?
Ethical Basis for Intergenerational Discounting
The ethical justification for applying a discount rate based on 'intrinsic impatience' to long-term climate policy rests on the principle that since individuals value their own present well-being more than their own future well-being, it is logical to extend this preference to value the well-being of the current generation more than that of future generations.
The ethical justification for applying a discount rate based on 'intrinsic impatience' to long-term climate policy rests on the principle that since individuals value their own present well-being more than their own future well-being, it is logical to extend this preference to value the well-being of the current generation more than that of future generations.
Intergenerational Ethics and Economic Discounting
Match each component of the argument regarding intergenerational discounting with its correct description.
An economic advisor makes the following argument for a long-term environmental policy: 'We observe that individuals, when making personal financial decisions, tend to value immediate benefits more than future benefits. This observed human tendency should be the basis for our public policy, meaning we should place a lower value on the well-being of future generations than on our own.' Which statement best identifies the logical leap in this reasoning that is the primary target of ethical criticism?
The Centennial Bridge Debate
A city planner argues against building a long-term flood defense system by stating, 'Market interest rates show that individuals value their own present comfort far more than their own comfort 30 years from now. Therefore, as a matter of policy, we should value the well-being of our generation far more than the well-being of a generation 100 years from now.' What is the fundamental ethical flaw in this line of reasoning?
