Marty 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 Science, Proceedings of the National Academy of Sciences, Journal of Environmental Economics and Management, 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 is Editor-in-Chief of the journal Marine Resource Economics, a co-editor of the Journal of the Association of Environmental and Resource Economists, and a past co-editor and current editorial board member of the Journal of Environmental Economics and Management. He is a member of the Scientific and Statistical Committee of the Mid-Atlantic Fishery Management Council and the Ocean Studies Board of the National Academies..
