An innovation of this study is that distributional effects of IAA value chain participation dynamics is investigated by examining economic impacts on all actors across the IAA value chains. We applied random-effects, standard fixed-effects, Heckit panel, and control function approaches to control for endogeneity of IAA value chain participation and unobserved heterogeneity. We found that IAA value chain participation is positively associated with household income and diet quality depicted by the consumption frequency of certain foods, especially fish consumption, and the benefits do not continue to accrue after discontinuing participation. The results also reveal that IAA value chain participation has higher impacts on the welfare of households who were involved in production related IAA value chain activities than upstream and downstream IAA value chain activities.Keywords: Integrated aquaculture-agriculture (IAA)welfare impactfixed effects modelcontrol functionindigenous householdsBangladesh AcknowledgementsThis article is part of the author doctoral dissertation, for which he was awarded the Joseph G.

This technique is referred to as co-location and can result in economic and environmental benefits. Using data from a choice experiment and random utility modeling, this research quantifies public preferences for various co-location options within the lease area of a developing wind farm off Virginia’s coastline. Our estimates show that the average Virginia public household is willing-to-pay upwards of $20 per 1,000 acres for co-location activities. By comparing our results to estimated implementation and management costs of each activity, there is a strong indication that the benefits of co-location exceed the costs. The experimental design of this study can be applied to other offshore wind installments around the U.S. and abroad.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"472 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135734526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A specific “Price Index” incorporating the leading aquaculture species produced by Turkish aquaculture, has been calculated for a five-year period spanning from 2016 to 2020. The empirical analysis is based on 60-month price and quantity data of chosen aquaculture species traded in a major wholesale fish market. Calculated prize index clearly indicates the noticeable effects of unusual economic and market dynamics on farmed fish prices. The significant increase in prices of agricultural inputs including aquafeed, electricity, fuel, maintenance of materials, and maintenance of buildings, as well as the impact of the Covid-19 pandemic in 2020, are the major factors influencing upward changes in price index. The “Turkish Aquaculture Price Index” is a practical tool that uses numerical expressions to reflect the periodic increase or decrease in the price of the aquaculture product commodity and makes significant contributions to understanding the price patterns and factors that have a cointegrated relation with the price changes in aquaculture market.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"27 1","pages":"267 - 281"},"PeriodicalIF":3.9,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46975607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper examines the opportunities and constraints for developing a stronger export market orientation in the Bangladesh fish and seafood sector. We discuss the role of public and private standards in food safety and quality, as well as empirical evidence for their effect on fish and seafood value chains. We assess the factors limiting diversification into fish and seafood exports and constraints to value chain enhancement. The experience of export-oriented shrimp value chains provides lessons for the aquaculture sector. High costs of compliance with public and private standards and inability to meet traceability requirements for food safety and quality present a significant challenge. In diversifying beyond domestic markets for fish and seafood, the policy challenge lies in striking an appropriate balance between intervention and guidance.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"27 1","pages":"498 - 522"},"PeriodicalIF":3.9,"publicationDate":"2023-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43774935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to traditional factors proposed by theory to explain profitability differences among firms such as size, efficiency, or capital structure, we also include in this analysis the strategies of product differentiation and diversification through vertical integration. A sample of aquaculture firms of the Nordic and Mediterranean-EU regions that were operating over the 2012–2019 period are identified in the Orbis database and selected for this research, employing an unbalanced panel made up of 5,427 observations. To carry out this analysis, we propose a random-effects model of firm profitability that allows to test the effect of the different explanatory variables as well as their regional differences. The findings of this research support that Nordic and Mediterranean-EU aquaculture are two business models with different characteristics, what is reflected in the economic performance of their firms.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"27 1","pages":"335 - 351"},"PeriodicalIF":3.9,"publicationDate":"2023-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46120443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mixed logit and latent class models were applied to estimate utility functions based on 459 samples collected using a choice experiment. The results indicate that Vietnamese consumers prefer sustainably farmed shrimp to conventionally farmed shrimp. Also, both food safety concerns and consumer knowledge vigorously promote sustainably farmed shrimp choices. Notably, the latent class results show that 73.5% of the respondents consider their environmental concerns about shrimp production when making decisions about consumption. The results indicate that placing information related to eco-friendly and food safety attributes on sustainability labels provides Vietnamese consumers with additional choices in the form of sustainably farmed shrimp. Finally, the simulated MXL results in the WTP space are more significant than those in the preference space, indicating that it is necessary to estimate the MXL in the WTP space to avoid specifying the parameter distribution subjectively by analysts.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"27 1","pages":"468 - 497"},"PeriodicalIF":3.9,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47754433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Investors are conscious of economic consequences of climate change for the salmon farming companies, hence their demand for climate-related financial disclosure has increased. This study discusses potential climate-related financial impacts imposed on the salmon aquaculture production as identified by the Task Force on Climate-related Financial Disclosure (TCFD). We use data from 2016 to 2021 available on the Carbon Disclosure Project (CDP) platform, and we show to what extent salmon aquaculture companies disclose their climate-related risks. We find that when the demand of investors for climate-related financial disclosure increases, more firms tend to comply with their requests, while based on the CDP’s evaluation system, the firms perform better in minimizing their carbon impact. We argue that when salmon aquaculture companies publish their climate-related financial disclosure, they ensure transparency for their investors and secure a smooth transition into a low carbon economy.","PeriodicalId":48854,"journal":{"name":"Aquaculture Economics & Management","volume":"27 1","pages":"441 - 467"},"PeriodicalIF":3.9,"publicationDate":"2022-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43175668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
