Critiquing the Game Theory Model for Climate Policy
A common model represents international climate negotiations as a two-player game where each country's most rational individual choice is to continue with 'Business as Usual' (BAU) emissions, leading to a collectively poor outcome for both. Critically evaluate the usefulness and limitations of this model in explaining real-world climate policy challenges. In your evaluation, consider at least two factors that this simplified, one-time interaction model might overlook.

In a simplified climate policy game involving two countries, each can choose between 'Business as Usual' (BAU) or a 'Restrictive Policy'. For each country, choosing BAU is the best individual response if the other country chooses the Restrictive Policy, and it is also the best individual response if the other country also chooses BAU. However, the outcome where both countries choose the Restrictive Policy is preferred by both over the outcome where they both choose BAU. Based on this incentive structure, why is the outcome where both countries choose BAU the most likely result?

Evaluating Solutions to the Climate Policy Dilemma
Two countries, X and Y, must independently decide whether to 'Restrict Emissions' or 'Maintain Status Quo'. The table below shows the possible outcomes (payoffs) for each country based on their combined decisions. The first number in each pair is the payoff for Country X, and the second is for Country Y. Higher numbers represent better outcomes.
Country Y: Restrict Country Y: Maintain Status Quo Country X: Restrict (10, 10) (2, 12) Country X: Maintain Status Quo (12, 2) (5, 5) Assuming each country seeks to maximize its own payoff without cooperating with the other, what is the most likely outcome of this one-shot interaction?
In a one-shot climate policy game, two countries independently choose between 'Restrict Emissions' and 'Business as Usual' (BAU). While the best outcome for the global environment and both countries combined is if they both restrict emissions, the individually rational choice for each is to pursue BAU regardless of the other's action. This leads to a (BAU, BAU) outcome, which is worse for both than if they had cooperated. Match each game theory concept to its correct description within this specific climate game scenario.
Consider a two-country climate policy game where each nation can either 'Restrict Emissions' or continue with 'Business as Usual' (BAU). The game is structured as a prisoners' dilemma, meaning the best outcome for both countries collectively is for both to 'Restrict Emissions'.
True or False: In this specific game structure, if Country A is guaranteed that Country B will 'Restrict Emissions', then Country A's individually rational, self-interested choice is to also 'Restrict Emissions'.
In a climate policy game where two countries independently choose their actions, if 'Business as Usual' (BAU) is the most beneficial choice for each country regardless of what the other country decides, then BAU is considered a ________ ________.
Critiquing the Game Theory Model for Climate Policy
Consider a climate policy scenario where two countries must each independently choose to either 'Restrict Emissions' or continue with 'Business as Usual' (BAU). The situation is structured such that each country's most rational, self-interested strategy is to choose BAU, no matter what the other country does. However, if both countries choose BAU, they end up in a situation that is worse for both of them than if they had both chosen to Restrict Emissions. Given this specific incentive structure, which of the following policy interventions would be most effective at fundamentally altering the game to make mutual restriction the more likely outcome?
