Última Structure and Power in Multilateral Negotiations: An Application to French Water Policy AgEcon Simon, Leo K.; Goodhue, Rachael E.; Rausser, Gordon C.; Thoyer, Sophie; Morardet, Sylvie; Rio, Patrick. Stakeholder negotiation is an increasingly important policymaking tool. However, relatively little is understood about the relationship between the structure of the negotiating process and the effectiveness with which stakeholders can pursue their individual interests. We apply the Rausser- Simon multilateral bargaining model to a specific negotiation process involving water storage capacity and use in the upper Adour Basin in southwestern France. We focus on a coalition of three stakeholder groups with aligned but distinct interests. In addition to the standard indices of bargaining power—the distribution of political weights (“access”) and players’ utilities if an agreement is not reached, our analysis identifies other less obvious sources of power....

AgEcon Elorrieta, Jose Ignacio; Castellano, E.; de Anguita, P. Martinez; Pellitero, M.; Rey, Concepcion. RESUMEN: Se propone una metodología para obtener un "precio social y ambiental óptimo" que pueda aplicarse al agua de riego en la Comunidad Foral de Navarra (CFN) de modo que maximice la internalización de los costes ambientales asociados al consumo no contemplados en el actual precio sin que el nivel general de la economía regional se resienta. Para ello se elabora un modelo económico sobre un Sistema de Información Geográfica (SIG) que permite cuantificar y valorar los costes ambientales en cada una de las subcuencas de la Comunidad. Para valorar íntegramente el agua, los elementos que se tienen en cuenta son: volumen, calidad y riesgo de afectar a los ecosistemas acuáticos y de ribera. Estos valores son estimados mediante métodos de valoración... Tipo: Journal Article Palavras-chave: Water; Social optimal price; GIS; Social Accounting Matrix (SAM); Externalities; Q25; Q14.

There has been substantial water resources development for agriculture in India but the emphasis has been mainly on the technical side - the building of the necessary institutions required for effective management of the resource has received little attention. Many believe that water resource management in India is heading for a crisis unless the institutions and related policies are rapidly transformed. In this light, the study examines key features of water institutions in India, applying new institutional economics fundamentals, as well as management theories of good governance. The study uses a survey of 29 water institutions and 450 farm households conducted across three states in India which face water scarcity and have attempted to address it...

Ano: 2009 URL: http://purl.umn.edu/51415 Structuring Exotic Options Contracts on Water to Improve the Efficiency of Resource Allocation in the Water Spot Market AgEcon Williamson, Brendon; Villano, Renato A.; Fleming, Euan M.. With the current drought in South-Eastern Australia highlighting the scarcity and value of inland Australia’s water resources, focus turns to how these resources can be allocated more efficiently. The first major step was taken almost a decade ago with the separation of land and water property rights allowing openly traded water markets. This study assesses the potential economic benefits that options contracts bring to the water market in the Murray Valley water market. Exotic call options are estimated using both Black-Scholes and skewness-and-kurtosis-amended Black-Scholes financial option pricing methods that are based on three years of data on water prices. While the presence of options would result in significant economic benefits in the more...

Economic theory suggests that price incentives can be used to encourage water conservation in residential consumers. Conservation water rates are designed to send price signals that encourage households to reduce discretionary water use in the long term. However, it is not always clear that conservation rates effectively provide meaningful incentives. Utilities themselves may also not have strong incentives to implement conservation rates. If conservation rates have a negative impact on revenue, or if they lead to increased revenue variability, utilities may have a disincentive to use them. In addition, block pricing structures (where unit water rate increases with water usage) may be inequitable, in the sense that the “revenue burden” is borne...

Ano: 2010 URL: http://purl.umn.edu/56510 INVESTIGATING THE ECONOMIC AND WATER QUALITY EFFECTS OF THE 2003 CAP REFORM ON ARABLE CROPPING SYSTEMS: A SCOTTISH CASE STUDY AgEcon Mouratiadou, Ioanna; Russell, Graham; Topp, Cairistiona; Louhichi, Kamel. The 2003 Common Agricultural Policy Reform aimed to promote the socio-economic and environmental sustainability of agricultural systems. An important question is how far the Reform has indeed encouraged farmers to contribute to achieving broad economic and environmental goals. The economic and water resource effects of the Reform have been explored for the case study area of the Lunan catchment, which is typical of Scottish arable cropping areas. Land use data analysis, bio-physical modelling and bio-economic modelling were used in combination to identify the effects of a range of scenarios. The results indicate only small changes in the cropping pattern and associated economic and water quality indicators as a result of the Reform, with the main changes...

Ano: 2008 URL: http://purl.umn.edu/44797 THE POLITICAL ECONOMY OF THE HUMAN RIGHT TO WATER AgEcon Branco, Manuel Couret; Henriques, Pedro Damiao de Sousa. A água é essencial à sobrevivência humana. Uma economia política humanizada, isto é dirigida para a satisfação das necessidades básicas, deve preocupar-se com a questão da disponibilidade e distribuição de água. No que diz respeito à satisfação das necessidades básicas, podemos afirmar que é relativamente fácil e barato fornecer água para todos. Porque razão, então existe uma desigualdade na distribuição? Esta desigualdade representa uma violação séria de um direito humano, como será desenvolvido à frente, e não deverá ser tolerada. Este artigo trata do papel que a economia desempenha no desigual exercício do direito humano de acesso à água potável. Este artigo examina como o discurso da economia dominante pode entrar em conflito com os direitos humanos...

Ano: 2008 URL: http://purl.umn.edu/108631 Water rights for variable supplies AgEcon Freebairn, John W.; Quiggin, John C.. The relative merits of different systems of property rights to allocate water among different extractive uses are evaluated for the case where variability of supply is important. Three systems of property rights are considered. In the first, variable supply is dealt with through the use of water entitlements defined as shares of the total quantity available. In the second, there are two types of water entitlements, one for water with a high security of supply and the other a lower security right for the residual supply. The third is a system of entitlements specified as state-contingent claims. With zero transaction costs, all systems are efficient. In the realistic situation where transaction costs matter, the system based on state-contingent claims is...

International agricultural trade has been growing significantly during the last decade. Many countries rely on imports to ensure adequate food supplies to the people. A few are becoming food baskets of the world. This process raises issues about the food security in depending countries and potentially unsustainable land and water use in exporting countries. In this paper, we analyse the impacts of amplified farm trade on natural resources, especially water. Farm exports and imports of five Latin America countries (Brazil, Argentina, Mexico, Peru and Chile) are examined carefully. A preliminary analysis indicates that virtual water imports can save valuable water resources in water-short countries, such as Mexico and Chile. Major exporting countries,...

Ano: 2011 URL: http://purl.umn.edu/114615 Experimental Economics and Water Policy AgEcon Duke, Charlotte. Experiments in economics and their application to policy design continue to gain increasing popular appeal. Australia is investing in training, capacity building and international partnerships to bring these skills to our policy makers. Economic experiments are used to test policy-related hypotheses: to examine the behavioural processes upon which the policy is built, identify policy bugs, confirm incentive mechanism performance, investigate new decision processes, and illustrate economic allocation systems to stakeholders. Experiments provide a new source of information to improve policy design. This paper explores a set of experiments conducted for the National Action Plan for Salinity and Water Quality Market Based Instruments Pilots Program. The...

We present a methodology allowing to introduce manufacturers and retailers vertical contracting in their pricing strategies on a differentiated product market. We consider in particular two types of non linear pricing relationships, one where resale price maintenance is used with two part tariffs contracts and one where no resale price maintenance is allowed in two part tariffs contracts. Our contribution allows to recover price-cost margins from estimates of demand parameters both under linear pricing models and two part tariffs. The methodology allows then to test between different hypothesis on the contracting and pricing relationships between manufacturers and retailers in the supermarket industry using exogenous variables supposed to shift the...

Ano: 2006 URL: http://purl.umn.edu/25685 A Stochastic-Dynamic Model of Costly Reversible Technology Adoption AgEcon Baerenklau, Kenneth A.; Knapp, Keith C.. We develop a stochastic-dynamic model of technology adoption that imposes fewer restrictions on behavior than do previous studies of similar decision problems. Like these previous studies, our model is forward-looking and can be used to demonstrate the additional "hurdle rate" that must be met before adoption will take place when the future state of the world is uncertain. Unlike these previous studies, our approach does not impose the untenable assumptions that investment in a new technology is irreversible or that technologies have unlimited useful lifetimes. Rather, we address the more reasonable situation of costly reversibility and limited lifetimes. Our solution method utilizes Bellman's equation and standard dynamic programming techniques....

This study determined a function demand for residential water. The data were stratified by geographic areas according to the level of regularity of water supply to the households. Income, price, number of rooms and persons in the households were found to be the main variables influencing the level of water consumption. Differences between: i) households connected to the water and sewage systems and those connected only to the water system; ii) households with up to 20 m3 of water consumption and those with consumption between 20 and 50 m3 and finally those with consumption above 50 m3 were surveyed. The results of the residential water demand were, in general, statistically significant and the coefficients presented the expected sign. These results are...

Ano: 2007 URL: http://purl.umn.edu/7058 Impacts of changing water price and availability on irrigated dairy farms in northern Victoria AgEcon Ho, Christie K.M.; Armstrong, Dan P.; Doyle, Peter T.; Malcolm, Bill. Farming systems throughout the Murray-Darling Basin are under increasing scrutiny from the perspective of ecological sustainability of farm and catchment systems. In northern Victoria, the dairy industry is a major user of water, and contributes to the environmental issues. Changes in irrigation water price, availability and policy will invariably impact on the viability of dairy farming in this region, but the diversity of dairy farm systems suggests that the impact will vary between farms. Two case study farms, a 'water reliant' farm and a 'fodder reliant' farm, were used to examine economic and social impacts of changes in water price, availability and policy.
