Evaluating Policy Interventions in a Resource Dilemma
Two towns share a common aquifer and must decide whether to 'Conserve' water or 'Overuse' it. The payoffs, representing the net benefits to each town, are shown in the matrix below (Payoff for Town A, Payoff for Town B). The current stable outcome is for both to overuse the resource.
| Town B | |||
| Conserve | Overuse | ||
| Town A | Conserve | (10, 10) | (2, 15) |
| Overuse | (15, 2) | (4, 4) | |
A regional authority is considering two different policy proposals to encourage conservation:
- Proposal 1: Provide a grant (subsidy) of 6 units to any town that chooses to 'Conserve'.
- Proposal 2: Impose a fine (tax) of 6 units on any town that chooses to 'Overuse'.
Evaluate both proposals. First, determine if each proposal is successful in making mutual conservation ('Conserve', 'Conserve') a stable equilibrium. Then, recommend one of the proposals, justifying your choice based on your analysis of how it alters the strategic incentives.

Analyzing Policy Impact on Strategic Cooperation
Consider a strategic interaction between two countries, Country A and Country B, regarding emissions policy. Each can choose to 'Restrict' or 'Don't Restrict' emissions. The payoffs, representing economic and environmental outcomes for each country, are shown in the matrix below (Payoff for A, Payoff for B).
Country B Restrict Don't Restrict Country A Restrict (5, 5) (1, 8) Don't Restrict (8, 1) (2, 2) In the initial game, the stable outcome is for both countries to choose 'Don't Restrict'. Which of the following policy-induced changes to the payoffs would successfully make mutual cooperation ('Restrict', 'Restrict') a stable equilibrium?

Designing a Policy to Overcome a Commons Dilemma
Consider the strategic interaction between two competing firms, Firm X and Firm Y, deciding whether to adopt a costly, industry-wide pollution-reducing technology. The payoff matrix below represents their profits, with the first number in each pair being the payoff for Firm X and the second for Firm Y.
Firm Y Adopt Don't Adopt Firm X Adopt (10, 10) (1, 12) Don't Adopt (12, 1) (3, 3) A government proposes a subsidy of 4 units to any firm that adopts the technology, regardless of the other firm's choice.
Statement: The proposed subsidy is sufficient to make mutual adoption ('Adopt', 'Adopt') a stable equilibrium.
Consider a scenario where two firms must decide whether to 'Adopt' a costly environmental technology or 'Don't Adopt' it. This situation often results in a dilemma where mutual non-adoption is the stable outcome, even though mutual adoption would be better for society. Match each policy intervention below with its most direct effect on the firms' payoffs, which could help make mutual adoption a stable equilibrium.
Consider a strategic interaction between two countries regarding emissions policy, represented by the payoff matrix below (Payoff for Country 1, Payoff for Country 2).
Country 2 Restrict Don't Restrict Country 1 Restrict (6, 6) (2, 9) Don't Restrict (9, 2) (3, 3) An international agreement proposes giving a subsidy, S, to any country that chooses to 'Restrict', regardless of the other country's choice. To make the outcome ('Restrict', 'Restrict') a stable equilibrium where neither country has an incentive to change its choice, the value of this subsidy S must be greater than ____.

Analyzing a Failed International Environmental Agreement
An economist is tasked with designing a policy to resolve a situation where two competing firms are overusing a shared resource, leading to a mutually damaging outcome. The goal is to alter the firms' incentives to make mutual conservation a stable strategy. Arrange the following steps into the correct logical sequence for analyzing and confirming the effectiveness of a proposed policy.
