Income Effects on Marginal External Cost
In an economic model where an individual's well-being is determined by both their income and their exposure to an externality like pollution, the marginal harm from an extra unit of pollution is not necessarily constant. Explain why the marginal external cost (MEC) experienced by a high-income individual could differ from that of a low-income individual, even if they both face the same incremental increase in pollution. Ground your explanation in the principles of utility.

A chemical plant's operations create runoff that pollutes a downstream river, negatively impacting a community of recreational fishers. A new regional economic development program is enacted, providing a substantial income subsidy to all residents, including the fishers. In a general economic model where the fishers' valuation of a clean river can be influenced by their income, what is the most likely effect of this income subsidy on the Marginal External Cost (MEC) of the pollution?

Comparing Externality Impacts in Different Economic Contexts
Statement: In a scenario where a factory's air pollution negatively impacts the well-being of nearby residents, if a new policy doubles the residents' income through an unrelated government program, the monetary value of the harm they experience from each additional unit of pollution will necessarily remain unchanged.
In a general economic model where the harm from an externality is evaluated based on an individual's utility, the marginal external cost is recognized as being a function of both the level of the externality-producing activity and the affected individual's ________.
Policy Implications of Income-Dependent External Costs
A resident's well-being is negatively affected by the noise level (Q) from a nearby construction site. In a general utility model where utility depends on both income and noise, assume that 'peace and quiet' is considered a normal good for this resident. If the resident receives a significant, unexpected inheritance that substantially increases their income, how would this change in income be expected to affect their Marginal External Cost (MEC) associated with an additional unit of noise?
Match each economic model assumption with its correct implication for the Marginal External Cost (MEC), which represents the marginal harm from an externality.
An economist observes that a community is willing to pay $20 to avoid the 10th daily freight train passing through their town, but is willing to pay $150 to avoid the 100th daily freight train. Assuming the community's income remains constant, what does this observation imply about the nature of the marginal external cost (MEC) of the train noise in this context?
