Information on sellers and buyers characteristics: added value to explain price formation at primary fish markets in managed French scallop fisheries ArchiMer
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.

Estimating Urban Residential Water-Demand with Increasing Block Prices: The Case of Perth, Western Australia AgEcon
Xayavong, Vilaphonh; Burton, Michael P.; White, Benedict.
This study uses panel data at suburb level to estimates the elasticity water demands in Perth, Australia from 1995 to 2005. After deriving the consumer’s water demand under a non-linear budget constraint, we estimate the water demand model, which accounts for how water (and other purchased goods) is used to satisfy fundamental desires of the household. We have applied the specification of price that provided the correctly estimated marginal price from the block tariff structure, and employed a maximum likelihood estimation technique to tackle the endogeneity and heteroskedasticity issues. Our estimation of water demand price elasticities are slightly higher (more elastic) than previous study in Perth, but broadly in line with other estimates in the...

The Future of European Agriculture - An Updated Outlook AgEcon
Isoard, Stephane; Witzke, Heinz Peter.
This paper reports the results of a European agricultural outlook exercise that updates former studies in three ways, i.e. in terms of timeframes, spatial coverage and policy context. This updated European agricultural outlook constitutes a key component of the forthcoming 'State of the Environment and Outlook report' of the European Environment Agency (EEA). Both activity variables and environmental indicators are reported for a baseline projection and alternative scenarios. The main findings include the following: European harvested land is expected to continue to be primarily used to fodder activities and production of cereals (80% of total area); yields increase is projected to be the main source of production growth in Europe over the next 20...

Environmental Targets and Shadow Prices of Bad Outputs in Organic and Conventional Farming AgEcon
Huhtala, Anni; Marklund, Per-Olov.
We present a framework for deriving shadow prices for negative environmental impacts regulated in agriculture. The shadow prices can be used as indicators of the costs of environmental regulation imposed as reflected in alternative farming technologies adopted. We illustrate our analytical findings with implications of the Finnish water protection policy measures on conventional and organic livestock farms over the period 1994-2002. Generally, the representative organic farm is found to be more technically efficient relative to its own technology than is the conventional representative farm. However, there is no statistical indication of a difference between these two particular representative farms in valuing the costs of undesirable output (manure) at...

The Market-based Lead Phasedown AgEcon
Newell, Richard G.; Rogers, Kristian.
The U.S. lead phasedown was effective in meeting its environmental objectives, and did so more quickly with the allowance of permit banking. The marketable lead permit system was highly costeffective, saving hundreds of millions of dollars relative to comparable policies not allowing trading or banking. Estimates suggest that transaction costs brought about only a modest reduction in program efficiency. The market-based nature of the program also provided incentives for more efficient adoption of new lead-removing technology, relative to a uniform standard. Distributionally, it is likely that the program was actually more responsive to the cost concerns of small refiners than a similar uniform standard would have been. The flexibility of the program likely...

The Relative Impacts of U.S. Bio-Fuel Policies on Fuel-Energy Markets: A Comparative Static Analysis AgEcon
Kim, C.S.; Schaible, Glenn D.; Daberkow, Stan G..
Rapidly declining gasoline prices from their record high during the summer of 2008, while ethanol prices remained relatively high, made it difficult for many bio-fuel policy modelers to fully explain the impacts of U.S. bio-fuel policies on fuel prices. Using profit-maximization models for blenders, refiners, and distillers, we conduct a comparative static analysis to measure the relative magnitudes of the impacts of tax credits and blending mandates on fuel-energy market equilibrium prices. Our results indicate that first, the prices of all fuels including conventional gasoline, ethanol, and blended gasoline decline as the biofuel tax credit increases, but they increase as the rate of the blending mandate increases. Second, the shadow value of a blending...

Timber Supply Model 96: A Global Timber Supply Model with a Pulpwood Component AgEcon
Sedjo, Roger A.; Lyon, Kenneth S..
This study involves an update of our earlier Timber Supply Model, which was fully developed in our book, The Adequacy Of Global Timber Supply by Sedjo and Lyon (1990), published by Resources for the Future. The new version, called Timber Supply Model 1996 (TSM96), uses an economic market supply/demand approach to project an intertemporal time path of the world's price and output level of industrial wood. As did the original TSM, the TSM96 provides projections of the time path of the equilibrium output levels of the several regions into which the world has been subdivided. A major new feature of TSM96 is that industrial wood, treated as homogeneous in the earlier study, has be subdivided into two different wood types -- pulpwood and solidwood. The supply of...

Conservation Programs: Will Grain Production Reclaim Acres in the South? AgEcon
Petrolia, Daniel R.; Ibendahl, Gregory A..
A state-level analysis of the Re-enrollment and Extension (REX) program on southern states indicates a positive relationship between percentage of tree acreage and Conservation Reserve Program (CRP) re-enrollment for states in which conservation acreage is dominated by trees. However, the relationship depends on crop mix where CRP acreage is dominated by grass. County-level analysis suggests that states will differ in how quickly they opt out of CRP. Of the states examined, Arkansas is the most likely to move land to corn, with Mississippi the least likely. Arkansas and Kentucky will switch to soybean first, followed by Mississippi and Georgia.

Risk Valuation in the Presence of Risky Substitutes: An Application to Demand for Seafood AgEcon
Huang, Ju-Chin; Haab, Timothy C.; Whitehead, John C..
We attempt to value health risks by combining traditional demand impact analysis with direct elicitation of individuals’ risk perceptions of food safety. We examine the impact of multiple risks of related goods on consumption of a risky good. We argue that the consumption of a risky good depends on both its absolute risk level and its relative risks to other risky goods. Seafood consumption in eastern North Carolina was studied. We elicited, in a survey, individual perceived risks as reference points to derive the economic value of reducing health risk in seafood consumption. Revealed and stated data were combined to trace out demand changes in response to absolute and relative risk reductions. Our results show that seafood consumption is affected by the...

Prescriptive use of Environmental Indices: A "How To" Guide for Conservation Programs AgEcon
Cattaneo, Andrea.
A framework for analyzing conservation programs that rank applications using environmental indices is presented. We derive the optimal bid from the farmer's perspective for both land retirement and working lands agri-environmental payment programs and we analyze how these solutions depend on program design parameters. The distinction is made between environmental objectives based on whether the farmer exercises control or not over the level proposed in a bid to participate in a program. The optimization model is solved analytically for two cases - a land retirement and a working lands program - highlighting the differences in the results.

Mixed Crop Livestock Farming Incorporating Agroforestry Orchards Facing the New Cap AgEcon
Ducros, Denis; Kephaliacos, Charilaos; Ridier, Aude.
In the context of the new CAP, decoupling subsidies from production should incite farmers to reorganize their production systems, particularly through diversification opportunities. In this paper we focus our analysis on the conditions that could permit the development of extensive orchards by modelling mixed crop livestock farms, which incorporate orchards. A mathematical programming model is built to simulate various intensification levels characterizing different technical pathways within the different farm activities (cattle breeding, forage fields, arboriculture). This model also enables us to take into account some environmental indicators related to these pathways. Moreover, the method illustrates technical complementarities existing within the...

Pricing Benefit Externalities of Soil Carbon Sequestration in Multifunctional Agriculture AgEcon
Hartell, Jason G..
“Multifunctionality” emphasizes the benefit externality properties of nonfood products that coincide with agricultural commodity production, some of which also have public-good properties. However, determining the willingness to pay for local benefit externalities is seen as necessary but daunting. This paper pursues the idea that the valuation process might first start by estimating the incentives required to supply various levels of a benefit externality. With the use of carbon sequestration through the adoption of no-till cultivation as an example of a multifunctional benefit externality, mathematical programming is used to derive representative price schedules. The implication for incentive prices are examined in light of risk aversion.

Forest Carbon Sequestration: Some Issues for Forest Investments AgEcon
Sedjo, Roger A..
A major problem being faced by human society is that the global temperature is believed to be rising due to human activity that releases carbon dioxide to the atmosphere; i.e., global warming. The major culprit is thought to be fossil fuel burning, which is releasing increasing amounts of carbon dioxide in the atmosphere. The problem of increasing atmospheric carbon dioxide can be addressed a number of ways. One of these is forestry and forest management. This paper examines a number of current issues related to mitigating the global warming problem through forestry. First, the overall carbon cycle is described, and the potential impact of forests on the buildup of atmospheric carbon is examined. A major focus is the means by which forests and forest...

Fisheries and Aquaculture in the Lagoon of Orbetello AgEcon
Martino, S..
This paper is an introductory note on the lagoon of Orbetello, defining its environmental peculiarities and productive capacity. The aquaculture firms (both extensive and intensive) and their markets are presented from an economic point of view, focusing on the importance which the area can have as a district, according to the national and regional framework on fisheries. In particular, the unitary strategy adopted in managing the fishery involves the resolution of environmental problems and the coordination of trade to compete with products imported from other Mediterranean countries.

High-Grading in a Quota-Regulated Fishery, with Empirical Evidence from the Icelandic Cod Fishery AgEcon
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...

An Agro-Economic Production Model for a Middle European River Basin - First Results of CAP Reform Scenario Calculations AgEcon
Henseler, Martin; Krimly, Tatjana; Wirsig, Alexander.
ACRE is an Agro-eConomic model for agricultural pRoduction on rEgional level. Based on an extension of Positive Mathematical Programming (PMP) this model was developed as a decision tool for politics with respect to questions of global change- and political scenarios. Currently, ACRE is applied in the RIVERTWIN-Neckar project and politic scenarios of the CAP reform 2003 were calculated. This paper introduces ACRE, its theoretical framework, and the first results of political scenario calculations, which where done for the Neckar river basin.

Do Consumers React to the Shape of Supply? Water Demand under Heterogeneous Price Structures AgEcon
Olmstead, Sheila M.; Hanemann, W. Michael; Stavins, Robert N..
Urban water pricing provides an opportunity to examine whether consumers react to the shape of supply functions. We carry out an empirical analysis of the influence of price and price structure on residential water demand, using the most price-diverse, detailed, household-level water demand data yet available for this purpose. We adapt the Hausman model of labor supply under progressive income taxation to estimate water demand under non-linear prices. Ours is the first analysis to address both the simultaneous determination of marginal price and water demand under block pricing and the possibility of endogenous price structures in the cross section. In order to examine the possibility that consumers facing block prices are more price-responsive, all else...

Organic Farming and the New CAP - Results for the Austrian Agricultural Sector AgEcon
Schmid, Erwin; Sinabell, Franz.
In 2003, the Common Agricultural Policy (CAP) has been reformed and decoupling direct payments from farm output is one of its core elements. We estimate the likely responses in organic product supply due to the reform at regional and sectoral levels. In addition, we analyse how the new programme for rural development, to be implemented in 2007, might affect organic farming. Our results show that organic farming will become more attractive after the 2003 CAP reform in Austria. Our results support the view that interactions among agri-environmental measures affect farmers' choice to maintain, abandon or adopt organic farming practices.
