Designing a Cost-Effective Water Management Policy
Hydrologists have established a 'guardrail' for a city's water supply: to prevent irreversible saltwater contamination of the main aquifer, total daily water extraction must not exceed 100 million gallons. An economist is hired to advise the city council. They are presented with two potential policy approaches to meet this non-negotiable limit:
- A uniform rationing system where every user (residential, agricultural, industrial) must cut their water use by a flat 20%.
- A cap-and-trade system where the total number of 'water permits' is capped at 100 million gallons, and users can buy and sell these permits from each other.
From the perspective of designing a cost-effective policy to stay within the established guardrail, which approach should the economist recommend, and why?

A government's scientific council has determined that to prevent the collapse of a critical fishery, the total annual fish catch must not exceed 500,000 tons. This limit is now a non-negotiable policy goal. An economist is asked to advise on the best way to implement this limit. Which of the following proposals best demonstrates a cost-effective approach to achieving the goal?
Evaluating a Climate Policy for Cost-Effectiveness
A city's public health authority establishes a 'guardrail' policy: to prevent a severe asthma crisis, the concentration of a specific airborne pollutant must not exceed 50 parts per million. An economist, hired to help implement this, should begin by evaluating whether the economic costs of meeting this standard are greater than the public health benefits.

An economist is tasked with advising on several public policy issues. Match each policy scenario with the primary economic approach the economist should take, based on the nature of the problem.
When a non-negotiable safety margin has been established to prevent a catastrophic outcome, the primary objective for an economist is to devise the most ____ implementation strategy.
An economist has been consulted after a panel of climate scientists established a mandatory 'guardrail' that national carbon emissions must be reduced by 40% within the next decade to avert irreversible ecological damage. Arrange the following steps in the logical order an economist should follow to design a policy response.
Evaluating an Economist's Policy Recommendation
A national food safety agency has established a strict 'guardrail' policy: the maximum allowable level of a certain pesticide residue on imported fruit is 2 parts per billion (ppb), a level set to eliminate any plausible risk of long-term health effects. This standard is now a non-negotiable policy constraint. An economist is brought in to advise the government. Which of the following recommendations best demonstrates the economist's proper role in this situation?
