Information on sellers and buyers characteristics: added value to explain price formation at primary fish markets in managed French scallop fisheries
Provedor de dados: 5
Autores: Lesur-irichabeau, Gabrielle; Guyader, Olivier; Fresard, Marjolaine; Leroy, C.; Latouche, K.; Le Grel, L.
The aim of this article is to explore, through a hedonic approach, the factors that might explain the price variability for the French-managed fishery of scallop at primary fish markets. In addition to factors classically identified in the current literature like intrinsic product characteristics or markets situation, the characteristics of operators are tested. The relationships of loyalty between sellers and buyers, and market assiduity are notably considered.

Buyback Programs: Goals, Objectives, and Industry Restructuring in Fisheries
Provedor de dados: 31
Autores: Kirkley,   James E.; Walden,   John B.; Waters,   James R.
National Oceanic and Atmospheric Administration Fisheries has conducted several buyback programs to reduce harvesting capacity in fisheries.  These programs have attempted to maximize capacity reduction given a fixed budget.  However, restructuring issues have not been considered.  We explore the possibility of satisfying three different buyback objective  We examine the black sea bass trap fishery and determine the number of vessels given different allowable catch levels and objectives of maximizing technical efficiency, capacity utilization, and vessels in the fishery.  We find considerable variation in the number of vessels allowed to remain in the fishery given the different objectives.

Marine Protected Areas as Fishery Policy: A Discussion of Potential Costs and Benefits
Provedor de dados: 31
Autores: Sanchirico,   James N.
Marine protected areas (MPAs) are currently receiving considerable attention as a "new" tool to control overexploitation. Many advocates argue that MPAs will provide a plethora of benefits ranging from improved habitat to higher fish stocks with little costs. Fishermen argue, not surprisingly, that the costs resulting from closing areas could be significant and need to be considered in the debate. In this paper, a set of biological, industry, and management hypotheses drawn from the literature analyzing the effects of MPAs are discussed. In doing so, a framework is presented that can be used to assess the expected returns to society from investing in MPAs.

Consumer Awareness, Perceptions and Behaviour Towards Farmed Versus Wild Fish
Provedor de dados: 31
Autores: Verbeke,   Wim; Brunso,   Karen.
This study provides empirical evidence about European consumer awareness, perceptions and behavior towards farmed and wild fish.  The evidence is based on three empirical studies: a consumer survey in Belgium in March 2003, focus group discussions with consumers in Belgium and Spain in May 2004, and a pan-European consumer survey with a sample of 4,786 fish consumers in Belgium, the Netherlands, Denmark, Span and Poland in November-December 2004.  Consumer awareness about the farmed or wild origin of fish is rather poor, particular among lighter fish user groups.  Perceptions are quite diverse across Europe.  Furthermore, perceptions often contrast with current scientific evidence, in particular with respect to behalf and nutritional value where consumers...

The Governance Economics of Capture and Aquaculture Fisheries
Provedor de dados: 31
Autores: Thomson,   Kenneth J.
The “new institutional economics” has influenced the study of public (or policy) choice, e.g. via the organization and incentives of “stakeholders”, and the analysis of international and other (e.g. state-private) agreements.  Stakeholders in fisheries policy include fisherman and their families and communities, processors, scientists, environmentalists, fish product consumers, other (non-fishing-)marine, coastal and land users, government fisheries departments, and taxpayers. These play different roles, with different weights, in policy discussions, as shown in the reformed Common Fisheries Policy (CFP) of the European Union.  The recently set up North Sea Regional Advisory Committee is used as an illustration.  Conclusions suggest that successful...

Can Co-Management Improve the Governance of   A Common- Pool Resource? Lessons From A Framed Field Experiment in A Marine Protected Area in the Colombian Caribbean
Provedor de dados: 31
Autores: Moreno-Sanchez,   Rocio del Pilar; Maldonado,   Jorge Higinio.
Complexities associated with the management of common pool resources (CPR) threaten governance at some marine protected areas (MPA). In this paper, using economic experimental games (EEG), we investigate the effects of both external regulation and the complementarities between internal regulation and non-coercive authority intervention—what we call co-management—on fishermen’s extraction decisions. We perform EEG with fishermen inhabiting the influence zone of an MPA in the Colombian Caribbean. The results show that co- management exhibits the best results, both in terms of resource sustainability and reduction in extraction, highlighting the importance of strategies that recognize communities as key actors in the decision-making process for the...

The Impacts of Marine Reserves on Limited-Entry Fisheries
Provedor de dados: 31
Autores: Sanchirico,   James N.; Wilen,   James E.
We utilize a spatial bioeconomic model to investigate the impacts of creating reserves on limited-entry fisheries. We find that reserve creation can produce win-win situations where aggregate biomass and the common license (lease) price increase. These situations arise in biological systems where dispersal processes are prevalent and the fishery prior to reserve creation is operating at effort levels in a neighborhood of open-access levels. We also illustrate that using strictly biological criteria for siting reserves (e.g., setting aside the most biological productive areas) will likely induce the most vociferous objections from the fishing industry. In general, we find that the dispersal rate and the degree the patches are connected play a significant...

Dynamic Effects of Grain and Energy Prices on the Catfish Feed and Farm Sectors
Provedor de dados: 31
Autores: Muhammad,   Andrew; Zheng,   Hualu.
This study examines the dynamic effects of grain prices and energy prices on catfish feed prices and the price of food-sized catfish at the farm level. Using the autoregressive distributed lag model and bounds testing procedure, a long-run relationship between feed and farm prices and their determinants was confirmed. Given the effect of corn and soybean meal prices on catfish feed prices, and catfish fish feed prices on farm prices, the long-run responsiveness of feed prices to a percentage increase in U.S. ethanol production is 0.325, and the responsiveness of catfish farm prices is 0.064. Although both feed and farm prices increase with ethanol production, the relatively small responsiveness of farm prices when compared with feed prices suggests that...

Import Demand Estimation and the Generalized Composite Commodity Theorem
Provedor de dados: 31
Autores: Asche,   Frank; Guttormsen,   Atle G.; Kristofersson,   Dadi; Roheim,   Cathy A.
A frequently encountered problem in import demand estimation is how to account for competition between imports and domestic production. Traditionally, use of the Armington model has been a way to handle this problem. This is a disaggregate model which distinguishes commodities by country of origin with import demand determined in a separable two-step procedure. The model appears frequently in analysis of international agricultural markets. However, the Armington model relies on a set of weak separability assumptions, which several authors have shown to be highly questionable. In this paper, a new aggregation theorem, the Generalized Composite Commodity Theorem (GCCT), is applied to test whether imports can be treated as a separate group. An advantage with...

This study examines the factors that influenced poor Indonesian farmers to invest in floating net aquaculture after being relocated due to a reservoir construction project. To compare three primary decision factors, credit accessibility, risk attitudes, and social learning, (i.e., learning effects from others’ experience), we analyze 16 years of socio-economic retrospective data collected in the field interviews exclusively for this study. Our analysis reveals that credit accessibility and risk attitudes are the most important factors that influence the rate of aquaculture investment. Social learning as well as household education also influences the investment decision significantly. Our results suggest that developmen t projects that involve voluntary...

The Benefits and Costs of Fish Consumption Advisories for Mercury
Provedor de dados: 31
Autores: Jakus,   Paul M.; McGuinness,   Meghan; Krupnick,   Alan J.
Mercury contamination of the Chesapeake Bay is a concern to health authorities in the region. We evaluate the economic and health effects of postulated recreational and commercial fishing advisories for striped bass on the Maryland portion of the bay. Awareness of and response to the advisory is estimated using a meta-analysis of the literature. Three values are estimated: welfare losses to recreational anglers, welfare losses in the commercial striped bass fishery, and health benefits. An estimate of percentage of consumer surplus loss is applied to the value of all fishing days in the bay to estimate recreational welfare loss. Welfare losses to the commercial fishery are estimated based on a model of supply and demand. Health benefits are estimated using...

Autores: Jones,   Keithly G.; Harvey,   David J.; Hahn,   William F.; Muhammad,   Andrew.
Estimates of price and scale elasticities for U.S. consumed shrimp are derived using aggregate shrimp data differentiated by source country. Own-price elasticities for all countries had the expected negative signs, were statistically significant, and inelastic. The scale elasticities for all countries were positive and statistically significant at the 1% level with only the United States and Ecuador having scale elasticities of less than one. For the most part, the compensated demand effects showed that most of the cross-price effects were positive. Our results also suggest that despite the countervailing duties imposed by the United States, shrimp demand was fairly stable.

A Comparison of Parametric Approximation Techniques to Continuous-Time Stochastic Dynamic Programming Problems
Provedor de dados: 31
Autores: Kompas,   Tom; Chu,   Long.
We compare three parametric techniques to approximate Hamilton-Jacobi-Bellman equations via unidimensional and multidimensional problems. The linear programming technique is very efficient for unidimensional problems and offers a balance of speed and accuracy for multidimensional problems. A comparable projection technique is shown to be slow, but has stable accuracy, whereas a perturbation technique has the least accuracy although its speed suffers least from the curse of dimensionality. The linear programming technique is also shown to be suitable for problems in resource management, including applications to biosecurity and marine reserve design.

Does Scarcity Exacerbate the Tragedy of the Commons? Evidence from Fishers’ Experimental Responses
Provedor de dados: 31
Autores: Maldonado,   Jorge Higinio; Moreno-Sanchez,   Rocio del Pilar.
Economic Experimental Games (EEGs), focused to analyze dilemmas associated with the use of common pool resources, have shown that individuals make extraction decisions that deviate from the suboptimal Nash equilibrium. However, few studies have analyzed whether these deviations towards the social optimum are affected as the stock of resource changes. Performing EEG with local fishermen, we test the hypothesis that the behavior of participants differs under a situation of abundance versus one of scarcity. Our findings show that under a situation of scarcity, players over-extract a given resource, and thus make decisions above the Nash equilibrium; in doing so, they obtain less profit, mine the others-regarding interest, and exacerbate the tragedy of the...

Economic Viability of Polyculture of Nile Tilapia and Australian Redclaw Crayfish in Yucatan State, Mexico
Provedor de dados: 31
Autores: Ponce-Marban,   Donny; Hernandez,   Juan; Gasca-Leyva,   Eucario.
Tilapia culture in rural communities of the state of Yucatan, Mexico, has been increasing in recent decades.  Polyculture of tilapia with other more commercially valuable species is an opportunity to substantially improve the economic yields of rural producers.  The economic viability of implementing a Nile tilapia with Australian redclaw crayfish polyculture was analyzed using profitability indicators such as internal rate of return (IRR) and net present value of the investment (NPV).  A bioeconomic model was developed to simulate three production densities (33/0, 33/20, tilapia and crayfish, respectively), accounting for investment recuperation in time horizons of 5, 10 and 15 years.  The model includes a biological sub-model describing the growth of...

Asset Pricing in Created Markets for Fishing Quotas
Provedor de dados: 31
Autores: Newell,   Richard G.; Papps,   Kerry L.; Sanchirico,   James N.
We investigate the applicability of the present-value asset pricing model to fishing quota markets by applying instrumental variable panel data estimation techniques to 15 years of market transactions from New Zealand's individual fishing quota market. In addition to the influence of current fishing rents (as measured by lease prices), we explore the effect of market interest rates, risk, and expected changes in future rents on quota asset prices. Controlling for these other factors, the results support a fairly simple relationship between quota asset and contemporaneous lease prices. Consistent with theoretical expectations, the results indicate that quota asset prices are positively related to declines in interest rates, lower levels of risk, expected...

This paper analyses the impact of farmed shrimp on the economy of ten municipalities in the Northeast of Brazil. A model of the municipal economy is developed and input-output tables are used to estimate indirect and induced impacts on job, income and municipal finances. It is concluded that farmed shrimp has a sizable contribution to job increases, in particular formal employment. Indirect and induced impacts are reduced because of spillovers to larger municipalities and other states. Income impacts can be sizable in particular in small counties. In general, the generated income represents a large share of total municipal product. In relation to municipal finance, direct contribution is rather small but indirect, through product increases and mainly...

Non-Market Values and Optimal Marine Reserve Switching
Provedor de dados: 31
Autores: Yamazaki,   Satoshi; Grafton,   R. Quentin; Kompas,   Tom.
A stochastic bio-economic model is constructed to analyse the effects of marine reserve ‘switching’ between a ‘no take’ area and a harvested area. The model accounts for both market and non-market values of the fishery. Estimated parameters from the red throat emperor fishery from the Great Barrier Reef are used.   Simulations show that an optimal switching strategy is, under a range of scenarios, preferred to fixed reserve and no reserve strategies.  An important outcome is that the non-market values associated with the size of the fishery substantially affect both the returns from switching and the closure time.

Cod today and none tomorrow: The Economic Value of a Marine Reserve
Provedor de dados: 31
Autores: Grafton,   R. Quentin; Kompas,   Tom.
The northern cod fishery was once one of the world’s largest capture fisheries. Using data from the fishery, this research calculated the economic value of a marine reserve using a stochastic optimal control model with a jump-diffusion process.   The analysis shows that, an optimal-sized marine reserve in this fishery would have prevented the fishery’s collapse and generated a triple payoff. Even if harvesting had been ‘optimal’ the profits from fishing would have been raised. The recovery time would also have decreased for the biomass to return to its former state and smoothed fishers’ harvests and profits. Following a negative shock, the chance of a catastrophic collapse would have been lowered.

This paper uses a non-market valuation study to elicit consumers’ preferences for a marine restoration programme in the Black Sea aiming to reduce the level of public health risk from bathing and improve water quality and the overall level of marine biodiversity. In this context, we administer a stated choice experiment in coastal settlements in Ukraine and Turkey and employ two tax revenue reallocation schemes as payment vehicles. One proposes the financing of the marine restoration programme by the reduction of the public budget for renewable energy and the second by the reduction of the public budget on training for civil servants. We examine the stated preferences and the subsequently derived economic value estimates in the two treatments with the aim...

Indian consumers have been buying fish from the unhygienic fish markets, but of late fish has become available at many of the multi-format retail outlets. Consumers’ behaviour at organized fish retail outlets in Mumbai has been studied. The majority of consumers are young (25-35 years) and belong to upper middle class. Fresh fish is the preferred choice and about 60 per cent consumers have emphasized on freshness rather than price of fish. About 97 per cent consumers have recently shifted to organized retail outlets from local markets for purchasing fish. The majority of consumers (84.3%) have been found to be species-specific while buying fish. Quality and convenience have been found to be the major factors responsible for shift from local markets....

Autores: Bhattacharya,   Poulomi; Ninan,   K.N.
This paper attempts a social cost-benefit analysis of scientific versus traditional shrimp farming in West Bengal, India. Using primary data, the paper shows that although intensive or scientific shrimp farming yields high returns as compared to traditional shrimp farming, when the opportunity costs and environmental costs of shrimp farming including disease risk are accounted for, scientific shrimp farming loses its advantage. In fact sensitivity analysis shows that if expected benefits were to fall short by 15% and costs rise by a similar proportion, scientific shrimp farmers report higher losses than traditional shrimp farmers. But large traditional shrimp farmers continue to report positive net returns. These results are also most pronounced for small...

Marine Protected Areas in Fisheries Management
Provedor de dados: 31
Autores: Greenville,   Jared W.; MacAulay,   T. Gordon.
The use of protected areas as a fishery management tool has been suggested as a hedge against management failures and variation in harvests. A stochastic bioeconomic model of a two-species fishery will be used to test the performance of protected areas as a management tool in a fishery with heterogenous environments. Protected areas are analysed under density-dependent and sink-source dispersal relationships between environments within the fishery. The model is applied to Manning Bioregion in NSW. Protected area performance as a tool for fisheries will be analysed given the existing management arrangement. The focus of the study is placed on the biological and economic characteristics that yield benefits to the fishery.

Autores: Dewbre,   Joe; Mishra,   Ashok K.
Using a model farm household resource allocation and data from the USDA-ERS Agricultural Resources Management Survey (ARMS), this study compares the effects of various categories of farm program payments on time allocation by farm operators and spouses. Results suggest that agricultural market transition payments (AMTA) increase leisure hours of both farm operators and spouses. Loan deficiency payments (LDP) and payments that combine market loan assistance (MLA) and disaster payments are shown to reduce leisure. The study also finds that AMTA payments exhibit a much higher degree of income transfer efficiency than the LDP and MLA payments.

Bang for the Buck: Cost-Effective Control of Invasive Species with Different Life Histories

Autores: Buhle,   Eric; Margolis,   Michael; Ruesink,   Jennifer L.
Strategies for controlling invasive species can be aimed at any or all of the stages in the life cycle. In this paper we show how to combine biological data on population dynamics with simple economic data on control cost options to determine the least costly set of strategies that will halt an invasion. We then apply our methods to oyster drills (Ocinebrellus inornatus), an economically important aquaculture pest that has been accidentally introduced worldwide. If the costs of intervention were the same across life stages, extermination of adults would be an inefficient way to control species with the population dynamics characteristics of invaders. In the oyster drill case, however, efficient control targets adults because they are much easier to find.

This paper analyses a fisheries management strategy, marine reserves switching, in which a non-fishing area is created, removed, or rotated from one site to another according to economic criteria through time. Using a dynamic optimisation framework under uncertainty, with the different fish dispersal processes, the optimal switching strategy and density distributions of the biomass, harvest, and net profit are simulated and compared under different management scenarios. This study will provide a decision and modelling framework for the design of marine reserves to achieve desired management goals.

A Preliminary Study of the International Marketing of Shrimp
Provedor de dados: 31
Autores: Castellini,   Alessandra; Ragazzoni,   Alessandro; Valentini,   T.
This paper aims to supply a comprehensive account of a particular sector of the fisheries industry.  TH increase of demand for fish products has involved an uncontrolled exploitation of marine reserves and fishing has reached its threshold of biological sustainability.  For these reasons, aquaculture has grown in a corresponding manner in the recent past.  The present survey starts from these considerations and aims to describe the general situation of world-wide, European and Italian aquaculture and then to examine the farming and marketing of a particular kind of product, Penaeus spp., which significantly affects global production in terms of value but not of quantity.

Catch-Quota Balancing in Multispecies Individual Fishing Quotas
Provedor de dados: 31
Autores: Sanchirico,   James N.; Holland,   Daniel S.; Quigley,   Kathryn; Fina,   Mark.
Individual fishery quotas (IFQs) are an increasingly prevalent form of fishery management around the world, with more than 170 species currently managed with IFQs. Yet, because of the difficulties in matching quota holdings with catches, many argue that IFQs are not appropriate for multispecies fisheries. Using on-the-ground-experience with multispecies IFQ fisheries in Iceland, New Zealand, Australia, and Canada, we assess the design and use of catch-quota balancing mechanisms. Our methodology includes a mix of interviews with fishery managers, industry representatives, and brokers, literature review, and data analysis. We find that a combination of incentives and limits on use rates for the mechanisms provide sufficient flexibility to the quota owner...

Efficiency Gains and Cost Reductions from Individual Transferable Quotas: A Stochastic Cost Frontier for the Australian South East Fishery
Provedor de dados: 31
Autores: Kompas,   Tom; Che,   Tuong Nhu.
In this paper efficiency gains and associated cost reductions from increases in traded quota are estimated with a stochastic cost frontier for the Australian South East Trawl Fishery (SETF). Estimation of this frontier also provides key information on the relative importance of input costs in the SETF, returns to scale, variations in costs as a result of trade in quota and the economic performance of each fishing vessel, year to year. Final estimations indicate that increases in the volume of quota traded have resulted in considerable efficiency gains and cost reductions in the SETF, ranging from 1.8 to 3.5 cents per kilogram for surveyed vessels for every one per cent increase in the volume of quota traded, or 1 to 2.4 per cent of total variable costs,...

Buyback Programs for Capacity Reduction in the U.S. Atlantic Shark Fishery
Provedor de dados: 31
Autores: Larkin,   Sherry L.; Keithly,   Walter R., Jr.; Adams,   Charles M.; Kazmierczak,   Richard F., Jr.
Declining fishery stocks, increasing fishing effort and adverse market conditions have produced difficult financial situations for fishermen worldwide.  Several high-valued fisheries are considered to be overcapitalized.  The purchase and permanent retirement of fishing vessels and/or permits under a buyback program is one approach for reducing fishing capacity.  Evidence from previous programs, however, suggests that buybacks are not a panacea for solving overcapacity problems.  Whether such programs can help rebuild stocks and improve the financial condition of fleets in any specific fishery depends on a multitude of factors.  We consider the potential of a buyback program for the U.S. Atlantic shark fishery.

The current study aims to examine the effectiveness of fisheries policies and specifically of the Greek Operational Programme for Fisheries, 2007-13. In specific, aims to examine and assess possible impacts generated, in the regional economy of Voreio and Notio Aigaio from its four axis, with particularity to the forth one. For this a regional Input-Output model was built in order to capture direct and indirect impacts in terms of output, employment and income. Results indicate that the dynamics of the fisheries sector in the regional economy are very weak and along with the continuous shrinking of the sector, leads to the necessity of supporting alternative vocational activities for the development of coastal rural areas.

None-of-These Bias in Stated Choice Experiments

Autores: Alfnes,   Frode; Steine,   Gro.
We conduct a within-sample test of hypothetical bias and parameter equality between a hypothetical stated choice (SC) experiment using pictures and a real choice (RC) experiments using products. With exception of the none-of-these alternative-specific dummy, we cannot reject parameter equality between the two datasets. However, when we estimate the models separately with no parameter restrictions, the SC experiment gave WTP estimates that were approximately 50 percent higher and marginal WTP estimates that were almost two times as high as the corresponding estimates from the RC experiment. However, even though the monetary value of the WTP disparity was large, the disparity between the WTP estimates from the two data sets was not statistically significant.

The Effects of ITQ Management on Fishermen’s Welfare When the Processing Sector is Imperfectly Competitive
Provedor de dados: 31
Autores: McEvoy,   David M.; Brandt,   Sylvia J.; Lavoie,   Nathalie; Anders,   Sven M.
In this paper we use a general model of imperfect competition to predict welfare changes within an open-access fishery transitioning to individual transferable quota (ITQ) management. Although related research has explored the effects of market power in the harvesting sector on ITQ performance, none have considered the implications of an imperfectly competitive processing sector. This study addresses this question specifically in the context of the Atlantic herring fishery, although its implications are relevant to all fisheries with similar industry structure. Our results show that ITQs could have a negative impact on fishermen’s welfare when processors have market power and the cap on aggregate harvest is binding or becomes binding with the...

Bioeconomic Evaluation of Substitution of Balanced Feed with Chaya (Cnidoscolus Chayamansa) Leaves in Tilapia Production
Provedor de dados: 31
Autores: Poot-Lope,   Gaspar Roman; Gasca-Leyva,   Eucario.
In Mexico, the culture of tilapia has developed in rural areas, where the main problem is low producer income.  The state of Yucatan also experiences this situation, and scarcity of money needed to purchase inputs results in complementary feeding with chaya (Cnidoscolus chayamansa), whose leaves are edible for humans and animals.  In this situation, CINVESTAV conducted experiments to determine the optimal level of substitution of balanced feed with ray chaya leaves.  The test with 25% and 50% reduced balanced feed complemented with chaya (ad libitum) did not show significant differences (P&gt;0.05) in growth compared to fishes fed with a complete ration of balanced feed (100% feed table).  A bioeconomic model was developed, including a submodel of growth...

RESUMEN: En este trabajo se analizan las estrategias relativas al proceso de internacionalización de la propiedad dentro del sector pesquero comunitario (en particular la conocida como "quota hopping", aplicada sobre todo por el sector pesquero español). En el desarrollo del proceso ha surgido un conflicto derivado de la defensa del carácter nacional de las cuotas asignadas en la Unión Europea siguiendo el Principio de Estabilidad Relativa. La implantación consiguiente de medidas proteccionistas tales como la exigencia de "vínculos económicos" ha alterado el contexto en que los agentes involucrados en el proceso de internacionalización tomaban sus decisiones. En nuestro artículo analizamos las diferentes estrategias y valoramos los resultados.   SUMMARY:...

Mathematical Bioeconomic Modelling of the Interaction Between Aquaculture and Open Sea Fisheries
Provedor de dados: 31
Autores: Antonelli,   Gervasio; Bischi,   Gian Italo; Lamantia,   Fabio.
We analyze the problem of an integrated management of fisheries by using fish farming as a tool for restocking fish populations depleted by overfishing pressure.  We first use a simple heuristic dynamic model, taken from a classical example of mathematical bioeconomics, in order to prove that fish restocking may be an efficient tool for sustainable fishery management in situations where excessive fishing effort is going to cause irreversible stock collapse.  Then we propose a two-compartments bieconomic mathematical model, with age structure and age specific harvesting and restocking, to mimic integrated interactions between aquaculture and open sea fisheries, where reared fish are used as substitutes for marine catches.  The model proposed in this paper...

Seafood Import Demand in the Caribbean Region
Provedor de dados: 31
Autores: Nguyen,   Giap V.; Jolly,   Curtis M.
Cointegration analysis and an Error Correction Model are used to estimate aggregate seafood import demand functions for selected Caribbean countries.  The results show that seafood import demand is price elastic.  Exchange rate has a negative effect on seafood import quantity.  Income and tourist arrivals have positive impacts on seafood imports.  Seafood import negatively affects domestic fishery production.  Tariff and production support policies reduce seafood imports, and enhance domestic production.   Both policies increase producer surplus, but a tariff reduces consumer surplus, and a production expansion policy increases consumer surplus. A production expansion subsidy is a more appropriate policy instrument than a tariff for small open economies,...

Autores: Borsky,   Stefan; Raschky,   Paul A.
This paper provides an empirical analysis of the role of intergovernmental relations on a country's effort to enforce the objectives of an international environmental agreement on an open access resource. Intergovernmental interaction allows signatory countries to observe compliance behavior of other signees and to punish non-compliance by applying bi- and multilateral sanctions. We use a cross-sectional dataset that contains country level information about compliance with Article 7 of the 1995 UN Code of Conduct for Responsible Fisheries. Our identification strategy combines a spatial autoregressive model with spatial autoregressive disturbances and an instrumental variable approach. We find a strong positive effect of other countries' compliance on the...

Autores: Sampaio,   Yony; Costa,   Ecio de Farias; Albuquerque,   Erica; Sampaio,   Breno Ramos.
The impact of farmed shrimp on the economy of ten municipalities are analyzed. A model of the municipal economy is developed and input-output tables are used to estimate indirect and induced impacts on job, income and municipal finances. It is concluded that farmed shrimp has a sizable contribution to job increases, in particular formal employment. Indirect and induced impacts are reduced because of spillovers to larger municipalities and other states. Income impacts can be sizable in particular in small counties. In general, the generated income represents a large share of total municipal product. In relation to municipal finance, direct contribution is rather small but indirect, through product increases and mainly transferences from State and Country...

According data authors believe that the fish-naming system is improving, however that lack of studies estimating the right amount of diversification in trade names for marine species seems so to be a weakness for a winning policy. Furthermore, seafood retailers seems to assume an important role on fraud management and government should support research...

Chimbote es uno de los principales puertos pesqueros del Perú y alberga una parte importante de las fábricas de harina de pescado del país. Sin embargo, luego de más de cincuenta años de existencia, este puerto está lejos de haberse convertido en un cluster dinámico formado por negocios pesqueros altamente especializados y diversificados.  Este trabajo pretende explicar esta situación, usando como tesis que la acción conjunta es primordial en el desarrollo de los clusters dinámicos y que ésta se ve obstaculizada en las actividades económicas que no cuentan con derechos de propiedad claramente establecidos, como es el caso de la pesca de anchoveta.

Equilibrium management of fisheries with altruistic overlapping generations

Autores: Ekeland,   Ivar; Karp,   Larry S.; Sumaila,   Ussif Rashid.
We imbed a classic fishery model, where the optimal policy follows a Most Rapid Approach Path to a steady state, into an overlapping generations setting. The current generation discounts future generations’ utility flows at a rate possibly different from the pure rate of time preference used to discount their own utility flows. The resulting model has non-constant discount rates, leading to time inconsistency. The unique Markov Perfect equilibrium to this model has a striking feature: provided that the current generation has some concern for the not-yet born, the equilibrium policy does not depend on the degree of that concern.

High-Grading in a Quota-Regulated Fishery, with Empirical Evidence from the Icelandic Cod Fishery
Provedor de dados: 31
Autores: Kristofersson,   Dadi; Rickertsen,   Kyrre.
Fishers in quota-regulated fisheries find it to their advantage to discard less valuable fish at sea to increase the value of their catch. A theoretical model describing the high-grading behavior of fishers is presented, and an empirical model is derived as well as a testing strategy to test for high-grading and to estimate the discarded amount of each grade. The model is applied to data for the Icelandic quota regulated cod fishery during the period September 1998 to June 2001. The results indicate that highgrading occurs in the Icelandic cod fishery for both long-line and net vessels. However, the discard rates are small, and the results clearly suggest that the ban on discards in Iceland has effectively dealt with high-grading. The estimated discard...

Private Options to Use Public Goods: Exploiting Revealed Preferences to Estimate Environmental Benefits
Provedor de dados: 31
Autores: Snyder,   Lori D.; Stavins,   Robert N.; Wagner,   Alexander F.
We develop and apply a new method for estimating the economic benefits of an environmental amenity. The method fits within the household production framework (Becker 1965), and is based upon the notion of estimating the derived demand for a privately traded option to utilize a freely-available public good. In particular, the demand for state fishing licenses is used to infer the benefits of recreational fishing. Using panel data on state fishing license sales and prices for the continental United States over a fifteen-year period, combined with data on substitute prices and demographic variables, a license demand function is estimated with instrumental variable procedures to allow for the potential endogeneity of administered prices.

Marine Reserves: Is There a Free Lunch?
Provedor de dados: 31

This paper employs a spatial and intertemporal model of renewable resource exploitation to investigate the effects of marine reserve creation. The model combines the H. S. Gordon/Vernon Smith hypothesis of a rent dissipation process with Ricardian notions that resources are exploited across space in a pattern dependent upon relative profitabilities. The metapopulation model employed here incorporates modern biological ideas that stress patch heterogeneity, linkages, and dispersal processes between patches. The spatial bioeconomic model is then used to simulate the effects of reserve creation under various ecological structures. We find, under certain parameter configurations and ecological linkages, that there is potential for a "double-dividend" where...

Quota Trading and Profitability: Theoretical Models and Applications to Danish Fisheries
Provedor de dados: 31
Autores: Andersen,   Jesper Levring; Bogetoft,   Peter.
Using Data Envelopment Analysis (DEA), we provide a framework to analyze the potential gains from quota trading. We compare the industry profit and structure before and after a free trade reallocation of production quotas. The effects of tradable production quotas depend on several technological and behavioral characteristics, including the ability to learn best practice (catch-up) and the ability to change the input and output composition (mix). To illustrate the usefulness of our approach, we analyze a dataset from the Danish fishery. We study the industry profit and structure under each of four sets of technological and behavioral characteristics.

Heterogeneity among agent types and second-best management for non-market ecological services
Provedor de dados: 31
Autores: Fenichel,   Eli P.
Second-best management affects different agent types differently, and heterogeneity among agents may create instances when only second best management is feasible.  Capital-theoretic bioeconomic modeling often has imposed representative agent assumptions that may not capture this heterogeneity.  Interactions between agent heterogeneity and second-best management have received little attention.  Such heterogeneity is particularly important when management actions do not directly affect extensive margin decisions.  We employ a microparameter model in a dynamic bioeconomic model to incorporate agent heterogeneity and intensive and extensive margin decisions for a nonmarket good, recreational fishing.  The model yields qualitatively different management...

Dynamics of Spatial Exploitation: A Metapopulation Approach
Provedor de dados: 31

We present a bioeconomic model of a harvesting industry operating over a heterogeneous environment comprised of discrete biological populations interconnected by dispersal processes. The model generalizes the H. S. Gordon [1954]/V. Smith [1968] model of open-access rent dissipation by accounting for intertemporal and spatial "Ricardian" patterns of exploitation. This model yields a simple, but insightful, framework from which one can investigate factors that contribute to the evolution of resource exploitation patterns over space and time. For example, we find that exploitation patterns are driven by biological and fleet dispersal and biological and economic heterogeneity. We conclude that one cannot really understand the biological processes operating in...

Fishing Quota Markets

Autores: Newell,   Richard G.; Sanchirico,   James N.; Kerr,   Suzi.
Fisheries worldwide continue to suffer from the negative consequences of open access. In 1986, New Zealand responded by establishing an individual transferable quota (ITQ) system that by 1998 included 33 species and more than 150 markets for fishing quotas. We assess these markets in terms of trends in market activity, price dispersion, and the fundamentals determining quota prices. We find that market activity is sufficiently high to support a competitive market and that price dispersion has decreased over time. Using a 15-year panel dataset, we also find evidence of economically rational behavior through the relationship between quota lease and sale prices and fishing output and input prices, ecological variability, and market interest rates. Controlling...

Whale-watching and Herring Fishing: Joint or Independent Production?
Provedor de dados: 31
Autores: Lee,   Min-Yang A.
The effects of "localized depletion" of a pelagic fishery (herring) on a non-extractive marine activity (tourism) are investigated. Proponents of the localized depletion theory claim that intense fishing effort can lead to areas that are unsuitable for predators like tuna, groundfish, and whales. This leads to poor outcomes for the fishing and whale-watching industries. However, there has been no consensus in the scientific community about the existence of this phenomenon. Localized depletion would be consistent with an economic theory of joint production, in which nearshore herring stocks are an input in production of both herring and whale-watching trips. A unique dataset of daily whale-watching outcomes is combined with fishing effort and oceanographic...

Buyer and Seller Responses to an Adverse Food Safety Event: The Case of Frozen Salmon in Alberta
Provedor de dados: 31
Autores: Maynard,   Leigh J.; Saghaian,   Sayed H.; Nickoloff,   Megan.
Fish is a low-fat protein source high in omega-3 fatty acids, but in 2004 consumers also heard that farmed salmon had high levels of polychlorinated biphenyl (PCBs). This research evaluated how Canadian consumers and processors reacted to the conflicting health messages. Demand estimates and time-series analysis of 2001-2006 frozen meat scanner data in Alberta, Canada show a significant drop in salmon expenditure share following the PCB finding. The industry responded by launching low-priced wild salmon products, which contributed to significant demand expansion. The analysis illustrates how a food safety threat was averted and even served as a catalyst for growth.

Autores: Chowdhury,   Nanzeen Kawshar; Kompas,   Tom; Kalirajan,   Kaliappa P.
This paper examines the effectiveness of different management tools, particularly input and quality controls on Bangladesh’s industrial trawl fishery. Results show that the efficiency of industrial trawl fishery comes from multiple owner managed vessels, export oriented vessels and registered vessels that are mainly engaged in double rigger trawling. Results also indicate that freezer vessels with small storage capacity, using small gear are relatively less efficient. This study shows that there is no depletion or reduction in marine fish stock over the period and shrimp vessels are technically more efficient than fish vessels.

Designing a Cost-Effective Marine Reserve Network: A Bioeconomic Metapopulation Analysis
Provedor de dados: 31
Autores: Sanchirico,   James N.
Marine reserves are gaining attention around the world as a tool to both conserve ocean resources and improve the productivity of fisheries. Using simulation analysis, we investigate in a limited-entry fishery comprising nine subpopulations the inherent bioeconomic trade-offs associated with cost-effective designs of marine reserve networks' that is, the trade-offs between the degree of connectedness of a site and the biological and economic heterogeneity. We find in many cases that closing two low-value patches can result in larger biological gains and lower costs than closing one high-value patch. We also simulate biological productivity effects after creation of a reserve and find that under special conditions, aggregate sustainable rents are maximized...
