Will a catch share for whales improve social welfare?
Abstract
We critique a proposal to use catch shares to manage transboundary wildlife resources with potentially high non-extractive values, and we focus on the case of whales. Because whales are impure public goods, a policy that fails to capture all nonmarket benefits (due to free riding) could lead to a suboptimal outcome. Even if free riding were overcome, whale shares would face four implementation challenges. First, a whale share could legitimize the international trade in whale meat and expand the whale meat market. Second, a legal whale trade creates monitoring and enforcement challenges similar to those of organizations that manage highly migratory species such as tuna. Third, a whale share could create a new political economy of management that changes incentives and increases costs for nongovernmental organizations (NGOs) to achieve the current level of conservation. Fourth, a whale share program creates new logistical challenges for quota definition and allocation regardless of whether the market for whale products expands or contracts. Each of these issues, if left unaddressed, could result in lower overall welfare for society than under the status quo.

Martin D. Smith
Smith studies the economics of the oceans, including fisheries, marine ecosystems, seafood markets, and coastal climate adaptation. He has written on a range of policy-relevant topics, including economics of marine reserves, seasonal closures in fisheries, ecosystem-based management, catch shares, nutrient pollution, aquaculture, genetically modified foods, the global seafood trade, organic agriculture, coastal property markets, and coastal responses to climate change. He is best known for identifying unintended consequences of marine and coastal policies that ignore human behavioral feedbacks. Smith’s methodological interests span micro-econometrics, optimal control theory, time series analysis, and numerical modeling of coupled human-natural systems. Smith’s published work appears in The American Economic Review, Nature, Science, Proceedings of the National Academy of Sciences, Journal of Environmental Economics and Management, the Review of Economics and Statistics, and a number of other scholarly journals that span environmental economics, fisheries science, marine policy, ecology, and the geo-sciences. Smith has received national and international awards, including the Quality of Research Discovery from the Agricultural and Applied Economics Association, Outstanding Article in Marine Resource Economics, and an Aldo Leopold Leadership Fellowship. His research has been funded by the National Science Foundation, the National Oceanic and Atmospheric Administration, the National Center for Ecological Analysis and Synthesis, and the Research Council of Norway. Smith has served as Editor-in-Chief of the journal Marine Resource Economics, Co-Editor of the Journal of the Association of Environmental and Resource Economists, and Co-Editor of the Journal of Environmental Economics and Management. He served as a member of the Scientific and Statistical Committee of the Mid-Atlantic Fishery Management Council and currently serves on the Ocean Studies Board of the National Academies.

My research focuses on evaluating environmental policies and improving methods and techniques for conducting these evaluations. While the field of policy evaluation is a broad one, my specific niche is in bringing rigorous quantitative methods to evaluate environmental policy innovations along four dimensions. (1) Evaluating the effectiveness of environmental policies and programs. This line of research uses statistical analysis to estimate the extent to which environmental policies such as information disclosure and management-based regulations actually improve corporate environmental performance, change household behavior, or improve individual environmental health indicators. (2) Evaluating strategic behavioral responses to non-traditional regulatory regimes. Environmental policies create incentives and in responding to these incentives, regulated entities sometimes behave strategically in ways that undermine program effectiveness. This line of research seeks to illuminate these strategic behavioral responses and quantify the magnitude of their impact. (3) Assessing the distributional impacts of these new regulatory regimes. My research in this area evaluates whether innovations in regulatory policy result in uneven distribution of environmental impacts on lower income or minority communities. (4) Evaluating the role of program evaluation in environmental policy. My research identifies the barriers to and facilitators of increased use of evaluation in environmental policy.

I study the conservation biology of long-lived marine vertebrates, particularly marine mammals, seabirds and sea turtles. My work, and that of my students, documents the effects of human activities on populations of these species. Our work involves field work, experimentation and modeling. I am particularly interested in the development and application of new conservation tools.
