Fishermen who use fishnets with small mesh sizes were invited to take part in an auction to exchange their fishnet for a fishnet with a bigger mesh size. Interestingly, we observe that the majority of fishermen are willing to exchange their fishnets without further compensation. Importantly, we observe that environmental perceptions and experiences with fishnets help explain the heterogeneity in bids. These findings provide useful information about limitations and possibilities of changing the behavior of individuals who strongly exploit resources.","PeriodicalId":49880,"journal":{"name":"Marine Resource Economics","volume":"38 1","pages":"101 - 111"},"PeriodicalIF":2.9,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49603728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Incorrect behavioral assumptions may yield ineffective incentives or interventions or even produce unintended consequences. To understand fisher behavior in a developing country, we surveyed 93 Indonesian snapper fishers. Results suggest they consider competing aspects such as income, personal reputation, and sociocultural norms when deciding where and what to fish; they update beliefs about location, bountifulness, and catchability of target fish stocks through direct observations, inferences over geographical similarities, and social interactions with other fishers, and they evaluate satisfaction economically as well as socially. Information sharing and social knowledge are likely port-specific, representing local sociocultural norms rather than being related to vessel size, target catch, or other demographics. The prevalence of information sharing and imitation patterns suggests that fisher decision-making in Indonesian snapper fisheries has a significant sociocultural component. We discuss implications for fisheries management models and for policy decisions.","PeriodicalId":49880,"journal":{"name":"Marine Resource Economics","volume":"232 ","pages":"85 - 100"},"PeriodicalIF":2.9,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41277078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fishing technology in the high seas being energy-intensive, higher oil prices should affect the fish markets. This research looks at price transmission between marine diesel oil and a global fishery commodity, frozen skipjack tuna (Katsuwonus pelamis) through a time series analysis combining four different methods to look for possible structural breaks and regime shifts in the relationship (Bai-Perron, Lavielle, Gregory-Hansen, Markov-switching). Our results prove that the long-run equilibrium between both prices is weakening after the turn of the 2010s. Explaining the drivers of change is of great interest for short-term forecast but also to build long-term scenarios where both supply and demand variables are likely to affect tuna markets.","PeriodicalId":49880,"journal":{"name":"Marine Resource Economics","volume":"38 1","pages":"29 - 46"},"PeriodicalIF":2.9,"publicationDate":"2022-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42661090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adequate provision of these services requires knowledge of the losses avoided, or, in other words, the economic benefits they generate. The latter can be difficult to measure for broader population segments, especially if forecasting services or features do not yet exist. We illustrate how stated preference tools and choice experiments are well suited for this case. Using as example forecasts of respiratory irritation levels associated with airborne toxins caused by Florida red tide, we show that 24-hour predictions of spatially and temporally refined air quality conditions are valued highly by the underlying population. This reflects the numerous channels and magnitude of red tide impacts on locals’ life and activities, which are also highlighted by our study. Our approach is broadly applicable to any type of air quality impediment with risk of human exposure.","PeriodicalId":49880,"journal":{"name":"Marine Resource Economics","volume":"38 1","pages":"1 - 28"},"PeriodicalIF":2.9,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42639301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article explores the sources, types, and distribution of marine litter and how production risk and technical efficiency in the trawl fisheries in Vietnam are affected by the presence of litter. The empirical analysis is conducted using data collected from a sample of 208 trawl fishers in Phu Yen, Khanh Hoa, and Ninh Thuan provinces. Our analysis indicates that primary sources of marine litter as reported by fishers are tourism and land-based emissions, with plastic being the dominant type. Litter accounts for 20% of the catch, making it a risk-increasing factor for trawl fisheries and causing technical inefficiency. Our findings emphasize the importance of developing policies for Vietnamese fisheries to jointly address production risks, improve technical efficiency, and decrease marine litter pollution.","PeriodicalId":49880,"journal":{"name":"Marine Resource Economics","volume":"38 1","pages":"65 - 84"},"PeriodicalIF":2.9,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46900704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Convex taxation is shown to be central in studies with static models but has rarely been explored in the context of dynamic fisheries. Literature shows that a linear tax regime is superior to quantity regulation when the stock estimate is uncertain in terms of economic gains and its ability to prevent resource extinction. Furthermore, when cost uncertainty is involved, a strictly convex tax on landings can prove even more efficient. A numerical example with a single-species demersal fishery having both ecological and economic uncertainty demonstrates the gain in value of moving from a linear to a strictly convex tax.","PeriodicalId":49880,"journal":{"name":"Marine Resource Economics","volume":"38 1","pages":"47 - 64"},"PeriodicalIF":2.9,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47325174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meanwhile, waterfront and near-water homes fuel a robust real estate market with many iconic regions, such as the Hamptons. Aging cesspools and septic systems are a paramount concern in the area. With approximately 74% of homes outside sewer systems, several jurisdictions are evaluating approaches to funding retrofits that would improve septic systems and water quality. It is therefore an ideal location to assess the impact that water quality has on home values; this paper investigates property sales near the Long Island Sound, South Shore Bays, and Peconic Estuary System. Results show that water quality has a significant impact on nearby home sales, with the largest effects generally seen nearest to the coastline. These results inform a discussion about potential benefits and costs of widespread septic tank and cesspool retrofitting, which is currently incentivized by grant and loan programs.","PeriodicalId":49880,"journal":{"name":"Marine Resource Economics","volume":"37 1","pages":"369 - 386"},"PeriodicalIF":2.9,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43357486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the model and three simplified versions, we show that assumptions of exogenous natural mortality and weight can lead to significant underestimation of optimal fishing mortality in both maximum sustainable yield (MSY) and maximum economic yield (MEY) scenarios for long-lived cannibalistic fish such as the Northeast Arctic cod. In addition, we show that the harvest, spawning stock biomass (SSB), and net present value (NPV) levels associated with optimal exploitation rates increase significantly with assumptions of exogenous natural mortality and weight. The underestimation of optimal fishing mortality, and the corresponding overestimation of SSB and NPV, is more significant in MSY than MEY scenarios. Meanwhile, the overestimation of harvest is more significant in MEY than MSY scenarios. The study also confirms that the Northeast Arctic cod fishery can achieve higher sustainable yield and NPV by changing the fleet composition and target reference points.","PeriodicalId":49880,"journal":{"name":"Marine Resource Economics","volume":"37 1","pages":"491 - 514"},"PeriodicalIF":2.9,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46069118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
