The increase in sea surface temperature (SST), a consequence of climate change, may lead to large-scale redistributions of global fish catch, including tuna in the Eastern Pacific Ocean (EPO). This paper applies the production function approach for modeling catch and SST using high-resolution gridded data for yellowfin and skipjack tuna catch in the EPO. We find a positive but nonlinear (i.e., logarithmic and quadratic) relationship between SST and the carrying capacity of tuna fisheries. The marginal product varies across species, distance from the equator, and the fishing method. For yellowfin tuna, the largest increase in catch occurs for unassociated and dolphin sets in the Northern EPO, while for skipjack tuna the largest increases in catch occur for unassociated and floating object sets in the Southern EPO. These thermal responses to ocean warming may lead to more segregated distribution and increased specialization in effort across the Eastern Pacific.

Bioeconomic modeling and seafood market analysis both have rich intellectual traditions that have contributed insights to understanding the economics of aquatic foods. This paper argues that these traditions, which developed mostly in parallel, should be combined more purposefully to understand management problems in fisheries and aquaculture. First, modeling the feedback between economic incentives and biological mechanisms is essential for avoiding management failure, and prices provide important incentives. Second, the form of management affects opportunities to generate value, influencing patterns of exploitation and the types of products that come from fishery resources. Third, price incentives in fisheries and responses to management depend on market context, including competition with aquaculture. By combining these insights with a modern empirical focus on counterfactuals, including both reduced-form and structural modeling approaches to causal inference, economists can inform policy and help to deliver a wide range of values from the production and consumption of aquatic foods.

Poverty reduction and conservation of natural resources are both global goals for sustainable development. However, it is not well understood how interventions to reduce poverty impact coastal communities and the fisheries they depend upon. This study explores the impact of a conditional cash transfer (CCT) program in Tanzania on local fish consumption decisions. To overcome the endogeneity of poverty to dependence on fisheries, we exploit a randomized controlled trial implemented in the initial rollout of the CCT. We allow for heterogeneous impacts based on initial household wealth and find that CCT participation increases demand for the poorest households in our study. We also differentiate by types of fish and find that dagaa—a low-value fish common in Tanzania—is primarily driving changes in fish consumption.

This paper explores why salmon harvesters in rural Alaska choose to sell their transferable permits. Household survey data from 10 remote Alaskan villages is combined with data on individual landings. Drift permit holders are more likely to sell their permits when average permit prices are low due to volatility in salmon runs or competition from aquaculture. These participants in the capital-intensive sector of the fishery are more likely to be in debt and liquidate assets under financial duress. Conversely, set net permit holders are more likely to liquidate their assets following life events such as the birth of a child or a divorce. For both types of permit holders, covariate shocks to salmon runs and prices are more important predictors of sale than individual productivity within the fishery. These results demonstrate that in the context of highly variable salmon runs, the transferability of property rights may undermine the economic sustainability of coastal communities.

Information on recreation site amenities is often sparse. Not only does this information scarcity have the potential to limit recreation activity, particularly if it causes users to forego recreation opportunities, but it also limits the ability of coastal communities to best allocate resources across site amenities to meet the needs of current and potential users and maximize the value of marine resources. In this paper, we estimate travel cost models that make use of a new dataset on fishing site characteristics to investigate the degree to which a large vector of amenities influences the site choice decisions of recreational anglers fishing in the Gulf of Mexico. We also uncover an important role of racial, ethnic, and income diversity considerations in recreation decision-making. We contextualize the valuation estimates, and combined with the findings of angler tendencies to avoid diversity, discuss the implications for coastal resource management.

Aquaculture production is typically located in rural coastal areas where the industry’s economic and environmental impact is highly visible. Aquaculture industry is at times controversial and subject to criticism regarding its externalities. For the industry to continue and expand, it needs support and acceptance from the public. We empirically examine the social support yfor aquaculture production in Norway using survey data, investigating the impact of economic as well as social factors. We find that people living in municipalities with aquaculture activities have a more favorable view of aquaculture production and become more positive with increasing presence of the industry. However, people also report that the economic benefits generated are not fairly shared in the communities where the production occurs. Our results show that proximity to aquaculture activities improve social acceptance, while perceptions of how equitably the economic benefits of aquaculture are distributed within communities also play an important role.

In this introduction to the special section, “The Economics of Coastal Communities,” we emphasize lesser-known or understudied connections between marine resources and communities in an effort to extend the lens of study beyond the economics of seafood. Facing pressure from all sides, resource managers, government agencies, and other entities have been calling for greater attention to these issues among researchers across disciplines. We provide a snapshot of how different organizations funding research and other innovation initiatives prioritize addressing current and future challenges in coastal regions. We summarize the complex setting of coastal communities as presented in the four papers in this section and outline points of departure for future research in the context of marine industries moving forward along the green transition path.
