Abstract: This paper builds and estimates a general equilibrium model with pollution externalities that enter household preferences to jointly explain income and price effects for the United States experience of structural change. First, we document three empirical regularities across countries: (a) a decline in energy and emissions intensity, (b) a negative correlation between a reallocation to services and pollution, and (c) a positive correlation between improvements in air quality and per capita GDP. Second, we build a stylized static multi-sector model featuring preferences over air quality. The presence of non-separable preferences between pollution and consumption plays a key role in the income effect. Since pollution causes larger damages on service consumption, a rise in air quality will accelerate the reallocation to services. Furthermore, we mathematically decompose price and wealth effects and provide bounds. Third, we augment the model with capital and estimate it using simulated method of moments, using the model to assess the costs and benefits of environmental taxes.
