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).

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.

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).

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.
