Economics And the Environment: An Analytical Framework for Policy and Regulation

Environmental economics sits at a genuinely important crossroads one where the logic of markets meets the fragility of ecosystems, and where getting the balance wrong carries consequences that extend well beyond any quarterly report or election cycle. This paper offers a systematic analytical treatment of environmental economics as a sub-discipline, tracing its intellectual roots, mapping its position within mainstream economic theory, and distinguishing it from cognate fields such as ecological economics and resource economics. We argue that pollution is, at its core, an economic problem: it arises from the structure of production incentives and consumer preferences, and it demands economic tools not merely technological ones for its resolution. The paper examines three interlocking challenges: how to determine the socially optimal level of pollution, how to measure the true costs of environmental damage, and how to design regulatory institutions capable of achieving abatement efficiently and equitably. We further situate these challenges within a broader assessment of global environmental quality, identifying population growth and rising per capita incomes as the principal structural drivers of intensifying environmental pressure. The analysis draws on established microeconomic theory, nonmarket valuation methods, and the comparative institutional economics of regulatory design, contributing to a growing body of scholarship that frames environmental governance as a problem of both economic efficiency and social justice.
