Critique of a Pollution Reduction Policy

Evaluating a Model for Environmental Policy

Consider an economic model where every individual in a community has preferences over their income (x) and the level of local air pollution (p), represented by the utility function U(x, p) = x + v(p). According to this model's structure, an individual's willingness to trade income for a one-unit improvement in air quality is independent of their income level.

Critiquing an Environmental Economic Model

An economic model is used to evaluate policies for reducing air pollution by assuming all individuals share a specific type of preference. Match each concept related to this model with its most accurate description.

In an economic model used to evaluate environmental policy, all individuals are assumed to have preferences represented by the function U(x, p) = x + v(p), where 'x' is a composite good representing all other consumption (often proxied by income) and 'p' is the level of pollution. A direct mathematical consequence of this functional form is that an individual's marginal rate of substitution between the composite good and pollution depends only on the level of 'p'. This leads to the critical, and often debated, policy conclusion that an individual's willingness to pay for a small reduction in pollution is independent of their level of ____.

Evaluating a 'Clean Air' Tax Policy

Analyzing a Flat-Fee Environmental Policy

In a town, two residents, Alex with an annual income of $40,000 and Bailey with an annual income of $200,000, are exposed to the same level of air pollution. An economic model is used to evaluate a new clean-air policy. The model assumes both individuals have identical preferences represented by the utility function U(x, p) = x + v(p), where 'x' is income and 'p' is the level of pollution. According to this specific model, what would be predicted about their willingness to pay for a small, identical reduction in pollution?
