The Dilemma of the Pest Control Game: Individual vs. Collective Rationality
In the pest control game, a type of prisoners' dilemma, the pursuit of self-interest leads to a collectively undesirable outcome. This happens because players' decisions create external effects; they do not take into account the costs their actions impose on others. By ignoring these external costs, both players are driven to a dominant strategy equilibrium that is worse for both of them than a cooperative alternative they could have achieved.

The Dilemma of the Pest Control Game: Individual vs. Collective Rationality
Two neighboring farmers must independently choose between using an inexpensive 'Polluting Method' for pest control or a more expensive 'Clean Method'. The table below shows the profit (payoff) each farmer receives based on their combined choices. The first number in each pair is Farmer 1's payoff, and the second is Farmer 2's.
Farmer 2: Clean Method Farmer 2: Polluting Method Farmer 1: Clean Method 3, 3 1, 4 Farmer 1: Polluting Method 4, 1 2, 2 Based on this payoff structure, both farmers acting in their own self-interest will choose the 'Polluting Method,' leading to the (2, 2) outcome. Which statement best analyzes why this happens, even though the (3, 3) outcome would make both of them better off?
In a classic two-player pest control game, the highest possible individual payoff for a farmer is achieved by using a cheap, polluting pesticide while the other farmer uses an expensive, clean one. The worst individual payoff comes from using the clean pesticide while the other uses the polluting one. Given this structure, if one farmer is guaranteed that the other will use the clean pesticide, their own self-interested best move is to also use the clean pesticide.

Competitive Pricing Dilemma
Two farmers, Anil and Bala, must independently decide whether to use a cheap but polluting pesticide ('Terminator') or an expensive but environmentally-friendly method ('IPC'). The table below shows the profits (payoffs) for each farmer based on their choices. The first number in each cell is Anil's payoff, and the second is Bala's. Match each concept to its correct representation in this game.

Analyzing Incentives in the Pest Control Game
In a standard pest control game, the outcome where both farmers independently choose to use a polluting pesticide is the dominant strategy equilibrium. This outcome is described as ________ because an alternative outcome exists (both using a clean method) where both farmers would be better off.

Analyzing a Business Scenario for External Effects
A company uses a robotic technology to produce olive oil. Each operational system requires exactly one worker and 400 kWh of energy to produce 100 liters of oil per day. If a worker's daily wage is $150 and the price of energy is $0.25 per kWh, what is the average cost to produce one liter of olive oil?
A chemical manufacturing plant's production process releases fumes into the air, which causes respiratory problems for residents in a nearby town. The plant's management team bases its production level decisions solely on its internal costs (labor, materials) and the market price of its chemicals. Which element of this situation is the clearest example of an external effect?

The Farmers' Payoff Dilemma
Consider a situation involving two neighboring farmers who must independently decide whether to use an inexpensive but polluting pesticide or a more expensive, environmentally-friendly one. The polluting pesticide contaminates a shared water source. If both farmers choose the polluting pesticide, they both end up with lower profits than if they had both chosen the friendly one. Why is it likely that both farmers will end up choosing the polluting pesticide?
In a situation where two individuals must independently choose an action, and each person's choice affects the other's outcome, the most beneficial result for the group is achieved when each individual selects the option that maximizes their own personal gain, regardless of the other's choice.
Individual Incentives vs. Group Outcomes
Two competing firms, Firm A and Firm B, sell an identical product. They must independently decide whether to set a 'High Price' or a 'Low Price'. If both set a High Price, they both earn a large profit. If both set a Low Price, they both earn a small profit. If one sets a Low Price while the other sets a High Price, the Low-Price firm captures the entire market and earns a very large profit, while the High-Price firm earns nothing. For each firm, setting a Low Price is the best strategy for itself, no matter what the other firm does.
Based on this scenario, match each term to its corresponding description.
The Paradox of Self-Interest
Two roommates must independently decide whether to spend an hour cleaning their shared kitchen or not. If both clean, they both enjoy a very pleasant kitchen. If only one cleans, that person bears the full cost of cleaning while the other enjoys a clean kitchen for free (the best outcome for the non-cleaner). If neither cleans, the kitchen becomes unlivable, which is the worst outcome for both. For each individual, the best personal choice, regardless of what the other does, is to not clean. What is the most likely outcome of this situation?
Two neighboring farms share a common groundwater source. Each farmer must decide independently whether to use a cheap, water-intensive irrigation method or an expensive, water-conserving one. If both conserve, the water level remains stable, and they both achieve sustainable, moderate profits. If both use the intensive method, the water level drops significantly, increasing their pumping costs and leading to low profits for both. However, if one farmer uses the intensive method while the other conserves, the intensive user gets very high profits, while the conserver's profits plummet. The most likely outcome is that both farmers use the intensive method. Why is this outcome considered economically inefficient?
