Environmental Policies Benefit Economic Development: Implications of Economic Geography

For over a century, starting with the work of Alfred Marshall (and also in resource economics), economic geography has emphasized the productivity of dense urban agglomerations. Yet little attention is paid to one key policy implication of economic geography’s core mechanisms: Environmental policies can aid economic development, per se—not hurting the economy to help the environment but advancing both objectives.We review mechanisms from economic geography that imply that environmental policies can deliver such win-wins: influences upon agglomeration of long-tanding natural conditions, like usable bays, which long were perceived as fixed yet now are being shifted by global environmental quality; agglomeration’s effects on other influential conditions, like urban environmental quality; and the effects of rural environmental quality on the flows to cities of people and environmental quality. Finally, we consider a geographic policy typology in asking why society leaves money on the table by failing to promote environmental policies despite the potential win-wins that we highlight.

Behavior, Environment, and Health in Developing Countries: evaluation and valuation

Subhrendu Pattanayak, Alexander Pfaff
Annual Review of Resource Economics (2009) 1:183–217

PDF link iconWe consider health and environmental quality in developing countries, where limited resources constrain behaviors that combat enormously burdensome health challenges. We focus on four huge challenges that are preventable (i.e., are resolved in rich countries). We distinguish them as special cases in a general model of household behavior, which is critical and depends on risk information. Simply informing households may achieve a lot in the simplest challenge (groundwater arsenic); yet, for the three infectious situations discussed (respiratory, diarrhea, and malaria), community coordination and public provision may also be necessary. More generally, social interactions may justify additional policies. For each situation, we discuss the valuation of private spillovers (i.e., externalities) and evaluation of public policies to reduce environmental risks and spillovers. Finally, we reflect on open questions in our model and knowledge gaps in the empirical literature including the challenges of scaling up and climate change.

Endowments, preferences, technologies and abatement: growth-environment microfoundations

Alexander Pfaff, Shubham Chaudhuri, Howard L.M. Nye
Int. J. Global Environmental Issues (2004) volume 4 number 4: 209-228

PDF link iconWill economic growth inevitably degrade the environment, throughout development? We present a household-level framework emphasising the trade-off between consumption that causes pollution and pollution-reducing abatement. Our model provides a simple explanation for upward-turning, non-monotonic paths of environmental quality during economic growth. Its innovation yields sufficient conditions that simultaneously address preferences and technologies. With standard preferences, an asymmetric endowment (i.e., at zero income, consumption is also zero but environmental quality is positive) leads low-income households not to abate, and further this condition is sufficient for an environmental Kuznets curve (EKC) for a wide range of abatement technologies. Without such an endowment, however, even strong economies of scale in abatement are, on their own, insufficient for an EKC

Aid, economic growth and environmental sustainability: rich-poor interactions and environmental choices in developing countries

Alexander Pfaff, Paulo Barelli, Shubham Chaudhuri
Int. J. Global Environmental Issues (2004) volume 4 numbers 1/2/3: 139-159

PDF link iconRich-poor interactions complicate the search for a stable Environmental Kuznets Curve (an ‘inverted U’ relationship between income per-capita and environmental degradation). We show that aid from richer to poorer countries to support investments in environment, in either of two forms, alters the income-environment relationships that otherwise exist, lowering levels of degradation in the poorer countries conditional upon their incomes. Yet even with environmental aid, in our model environmental quality eventually falls as economic growth continues, although ongoing innovation could change that conclusion. In light of this result, we show that subsidies to clean goods, one form of technological-transfer aid programme, dominate income transfers as environmental aid policy by the rich. Given that aid matters, we then show that when rich countries degrade the environment, a perverse effect exists: when an aid-giving country becomes richer, it gives less aid to the poor country. This is stronger when that degradation is durable, that is, when consumption and degradation by the rich country in the past has durable effects upon the environment.

Environmental Self-Auditing: setting the proper incentives for discovery and correction of environmental harm

Alexander Pfaff, Chris William Sanchirico
Journal of Law, Economics & Organization (2000) volume 16 number 1: 189-208.

PDF link iconMany firms conduct “environmental audits” to test compliance with a complex array of environmental regulations. Commentators suggest, however, that self-auditing is not as common as it should be, because firms fear that what they find will be used against them. This article analyzes self-auditing as a two-tiered incentive problem involving incentives both to test for and to effect compliance. After demonstrating the inadequacy of conventional remedies, we show that incentives can be properly aligned by conditioning fines on firms’ investigative effort. In practice, however, the regulator may not be able to observe such effort. Accordingly, we propose and evaluate the use of three observable proxies for self-investigation: the manner in which the regulator detected the violation; the firm’s own disclosure of violations; and the firm’s observed corrective actions. Each method has its own efficiency benefits and informational requirements, and each is distinct from EPA’s current audit policy.
