ABSTRACT

ONE OF THE GREAT STRENGTHS and weaknesses of environmental economics is its emergence from neoclassical economics—a discipline that grew and thrived in an era largely unaware of and unconcerned about environmental issues. Figure 6–1, familiar to all first-year economics students, captures the essence of the neoclassical economic model of the economy. It is basically a closed system with mutual exchanges between firms and households. Consumers provide their labor to producers, and they, in turn, sell the resulting goods back to consumers. As illustrated in Figure 6–2, environmental economics made a major addition to this model by adding another entity to this simple flowchart: the environment, which sits principally beside the producer’s side and represents the repository for the waste generated by the industrial system of production. Table 6–1 lists the principal types of pollutants that have been the common focus of environmental economics. The goal is to internalize externalities in order to reduce economic inefficiency from a social perspective. The overall goal of maximizing economic growth to increase human welfare remains the central thrust. This is fundamentally neoclassical economics with minor modifications.
