At the recent Allied Social Science Associations (ASSA) meeting in Atlanta, GA, Professor Kathy Segerson was awarded the 2009 Publication of Enduring Quality Award by the Association of Environmental and Resource Economists (AERE). This award, instituted in 1989, is given annually to the author(s) of a publication that is deemed to have had a lasting and significant impact on the field of environmental and natural resource economics. Professor Segerson received the award for her paper entitled “Uncertainty and Incentives for Nonpoint Pollution Control,” which was published in the Journal of Environmental Economics and Management in 1988. During the award ceremony, the presenter of the award noted that “Dr. Segerson’s paper was the first to incorporate the fundamental characteristics of nonpoint source pollution into a formal theoretical model to study efficient tax schemes.” This paper proposed an innovative policy approach to controlling agricultural production based on observations of ambient water quality, which some have termed the “Segerson mechanism”. In recent years, it is spawned a number of studies that have examined the incentives created by this mechanism and related ambient-based policies using economic laboratory experiments.
