Learn Before
A policy analyst is using a simulation spreadsheet to evaluate a long-term climate project that promises a significant environmental benefit in 100 years. The analyst's initial calculation, using a moderate discount rate, shows the project's present value is too low to justify its upfront costs. To argue in favor of the project by making its future benefits appear more valuable in today's terms, the analyst must adjust the spreadsheet's discount rate slider ____.

Evaluating a Long-Term Environmental Project
A government agency is evaluating two environmental projects. Project Alpha has a large upfront cost but is projected to yield a massive benefit in 100 years. Project Beta has a smaller upfront cost and is projected to yield a moderate benefit in 10 years. If the agency decides to switch from using a high discount rate to a low discount rate for its evaluation, what is the most likely impact on the projects' perceived value?
A policymaker believes that the well-being of future generations 100 years from now is nearly as important as the well-being of the current generation. To reflect this belief when calculating the present value of a long-term environmental project's benefits, the policymaker should select a high discount rate.
Analyzing the Effect of Time on Present Value
A student uses a spreadsheet to calculate the present value (PV) of receiving $1,000 at two different future points in time, using three different annual discount rates. The results are summarized in the table below.
Discount Rate PV of $1,000 in 10 Years PV of $1,000 in 100 Years 1% $905 $369 5% $614 $8 10% $386 <$1 Based on an analysis of this data, which of the following statements is the most accurate conclusion?
Choosing a Discount Rate for a Climate Adaptation Project
Match each type of discount rate with the statement that best describes its underlying assumption or policy implication for long-term projects like climate change abatement.
Manipulating a Present Value Simulation
An economist is calculating the present value of a future payment of $1,000 under four different scenarios. Arrange the following scenarios in order from the one that yields the HIGHEST present value to the one that yields the LOWEST present value. You do not need to perform the exact calculations.
