Publication: Technical Efficiency of Shrimp Fishery in South Carolina, USA
Abstract
The increased inflow of imported shrimp into the US has lowered shrimp prices in the marketplace and with it, ex-vessel prices received by shrimp fishermen. Proposed remedies are aimed at strategies to increase the prices received by domestic producers. This study looks into issues related to the production side by estimating the technical efficiency of South Carolina shrimp boat operators. Estimates using a stochastic production frontier method show that average efficiency is 46%. This finding has strong implications on the long-term survival and viability of the local shrimp industry as it continues to face competition from low-priced imports.

Publication Pacific Islands - Fisheries sector engagement strategy(World Bank, 2012-03-05)The World Bank's 11 Pacific Island member countries are a diverse group in terms of economic and social conditions. Five are least developed countries, with annual per capita Gross Domestic Product (GDP) as low as US$ 700, while in some of the territories average incomes are comparable to those in wealthy industrialized countries. Population densities and growth rates, land areas and the level of urbanization all display similarly wide ranges. There is a great diversity of cultures and languages. What they have in common is that all are islands surrounded by the Pacific Ocean, with jurisdiction over areas that are many times (in some cases thousands of times) their land area. All derive significant economic and social benefits from their marine resources, with many coastal communities depending on them for their livelihoods. Several have large and important freshwater fisheries. All identify their living aquatic resources (for fisheries, aquaculture and non-extractive uses mainly related to tourism) as a major opportunity for economic growth and development. In some cases, they represent one of the only opportunities. Reviews of the importance of fish as a source of food for Pacific Island populations have found that annual per capita consumption of fishery products in all cases exceeds the global average of 16.5 kg. In several small island countries, where opportunities to produce other food are very limited, fish consumption is among the highest in the world. Fishing also plays an important cultural role for men and women in many of the region's coastal communities.Publication Fisheries and Aquaculture Sector Study : Final Report, Fisheries and Aquaculture Sector Study(Washington, DC, 2005-02)The fisheries and aquaculture sectors are significant contributors to the economy of Vietnam. Direct production value (at the farm gate or on the wharf) in 2003 was approximately $1.7 billion. Both sectors have expanded rapidly over the past decade, with marine fisheries production rising from 800,000 to 1.5 million tons over the period 1990 to 2003. Aquaculture production has increased rapidly to around one million tons, while inland fisheries contribute in excess of 200,000 tons. The study has two main objectives: (i) to review the status and needs of the fisheries, aquaculture and aquatic resource management in Vietnam; and (ii) to identify key areas of intervention that can reduce poverty, increase production and improve environmental management of the sectors on a sustainable basis. The study concludes by summarizing major development priorities and next steps for the sectors to develop on principles of shared management in fisheries and aquaculture planning, development and management.Publication The Political Economy of Natural Resource Use : Lessons for Fisheries Reform(World Bank, Washington, DC, 2010-04-01)The release of 'Sunken billions: The economic justification for fisheries reform' has drawn renewed attention to the enormous loss of wealth suffered in fisheries each year due to weak fisheries governance and the need for fundamental fisheries reform. Such reform calls for addressing the issues plaguing the world's fisheries, such as persistent overfishing and fleet overcapitalization, and addressing the political economy challenges of developing country-specific pathways of reform. Despite growing evidence of success in selected fisheries, less than two percent of the world's fisheries have actually undergone effective reform because of these challenges. At the same time, it is estimated that the world's fisheries could generate at least fifty billion US dollars per annum and the economic benefits generated could be much higher if management systems were established to enable investment in growing this important economic sector in a sustainable manner. The potential pay-off from economic fisheries reform is not only globally significant for the sector, it is crucial for enhancing economic growth and alleviating poverty in developing countries with significant fisheries assets. This report seeks to move this debate forward by discussing key lessons drawn from reform experience in the wider natural resource sector that might inform successful reform in fisheries.Publication How Might Shadow Price Restrictions Reduce Technical Efficiency? Evidence from a Restricted DEA Analysis of Coffee Farms in Vietnam(2011)We use data from smallholder coffee farms in Vietnam to measure the technical efficiency of coffee producers, and the degree to which potential restrictions on the shadow prices of chemical inputs might reduce overall efficiency among these farmers. Using input-oriented data envelopment analysis (DEA) we find the use of pesticide and herbicide accounts for a relatively small proportion of overall technical efficiency in the sample. We place restrictions on input shadow prices and show that restricting their importance does not dramatically alter patterns or measures of short-run efficiency.Publication Wealth-Based Fisheries Management: Using Fisheries Wealth to Orchestrate Sound Fisheries Policy in Practice(2009)The importance of resource rent in fisheries has long been acknowledged. By generating such rents, economically efficient management systems increase value added and the sector's contribution to the gross domestic product (GDP) and growth. However, despite the successful adoption of such systems in some countries around the world, economics continues to have relatively little influence on fisheries policy. This lack of influence is particularly noticeable in developing countries, precisely where the contribution that effectively managed fish resources might make to the GDP is most urgently needed. The key requirement to increase the adoption of economically rational fisheries management is to convince policymakers to focus explicitly on the wealth-generating potential offish resources. Such a focus provides a general policy framework within which other approaches, such as rights-based, incentive-based, and ecosystem-based, may be nested. This approach is likely to prove more effective in influencing policy, especially in situations where rights-based systems either will not work or are politically unacceptable.
