ANÁLISE DA SUSTENTABILIDADE DA PRODUÇÃO DE BIODIESEL NO BRASIL AgEcon
Santos Junior, Silvio; Dias, Marcelo Fernandes Pacheco; Mendonca, Erica Silva; Rosa, Nadir Paula Da; Silva, Tania Nunes da.
Muitos compostos químicos são encontrados na atmosfera terrestre atuando como “gases de efeito estufa”. Eles são importantes uma vez que impedem a reflexão total dos raios solares, Entretanto, os níveis de alguns desses gases, principalmente o gás carbônico (CO2), vem aumentando a uma taxa de 25% desde o processo de industrialização em larga escala, iniciado a 150 anos atrás. Nos últimos 20 anos o CO2 vem correspondendo a 84% dos gases provenientes das atividades humanas, e, 82% dele é resultante da queima de combustíveis fósseis. Considerando que o aumento da população e o surgimento de novas tecnologias continuam demandando energia de forma incremental, é imperativo a busca de soluções energéticas alternativas, mais sustentáveis. Neste contexto, a...

Are Two Economic Instruments Better Than One? Combining Taxes and Quotas under Political Lobbying AgEcon
Finkelshtain, Israel; Kan, Iddo; Kislev, Yoav.
Direct commands, market based, or combined, whichever is the government's mean of intervention, is expected to raise political lobbying and pressure. This study offers a political-economic model of an industry, which is regulated by an integrated system of both direct and market based policies. The model is used for a normative theoretical analysis and as a basis for a structural econometric framework. Exploiting a unique data set that describes the regulations of irrigation water in Israel during the mid eighties by means of quotas and prices, the political and technological parameters of the model are structurally estimated and used to assess the relative efficiency of quotas, prices and integrated regulation regimes.

Diseno de un indice sintetico de desarrollo sostenible y aplicacion a la Union Europea AgEcon
Laxe, Fernando I. Gonzalez; Palmero, Federico G. Martin.
En el presente artículo se establecen las bases metodológicas y se diseña un índice sintético global de desarrollo sostenible que cumple tres condiciones: se adapta a los principios de Presión – Estado – Respuesta, adopta los mandatos de la Agenda 21 Local y se adecua a los cuatro componentes o dimensiones básicas de la sostenibilidad: institucional, medioambiental, económica y social. A partir de dicha metodología se construye el índice sintético sobre el cómputo de 78 variables, 37 subindicadores y 13 indicadores, agrupados éstos en las cuatro dimensiones citadas para, a continuación, proceder a su aplicación a los países de la UE.

ECONOMIA DO MEIO AMBIENTE:ASPECTOS TEÓRICOS DA ECONOMIA AMBIENTAL E DA ECONOMIA ECOLÓGICA AgEcon
Souza, Roberta Fernanda Da Paz De.
Os efeitos gerados pela manutenção do atual padrão de consumo sustentado pelo homem tornam cada vez mais evidente a inviabilidade do mesmo. A pressão exercida sobre os recursos naturais enquanto fatores de produção e sumidouros depositários de resíduos oriundos da utilização desses, faz com que as questões referentes a possíveis limites à sua utilização sejam discutidas. A teoria econômica vem buscando, através de seu arcabouço, determinar formas eficientes e sustentáveis para a utilização dos recursos ambientais. Tais teorias apresentam argumentos sobre o limite, as características, as finalidades dadas aos recursos naturais, entre outros. A Economia Ambiental e a Economia Ecológica são correntes metodológicas que buscam interpretar o problema ambiental e...

Managing a Common Renewable Resource in Asymmetric Information AgEcon
Catro, D. Fuentes; Jayet, Pierre-Alain; Rotillon, Gilles.
The clear definition of property rights is not a sufficient condition to prevent congestion effects in commons. In this paper we present how interesting can be the coordination among owners in the preservation of the common good. Our approach takes into account economic dynamics and incentive mechanisms in a hidden information context. We consider a natural resource which is being used up for a continuum of producers on a common property regime. We also consider that each producer has an individual performance index which is a hidden information of the rest of players. We introduce coordination in the sense of a global maximization of the joint profit. If there is no coordination among the producers, their behavior leads to complete rent dissipation....

Oil Revenues, Ethnic Fragmentation and Political Transition of Authoritarian Regimes AgEcon
Cologni, Alessandro; Manera, Matteo.
Natural resources are generally associated to negative effects on the political environment of a country. This paper explores the impact that oil revenues have on the establishment of a given political system. Based on previous literature, a political economy perspective is employed. A simple game theoretical approach in order to explain the relationships between oil revenues, political instability (conflicts) and emergence of different political systems is presented. The implementation of particular redistributive fiscal policies together with the possibility that paternalistic or “predatory" autocracies emerge are considered. Under certain circumstances, a process of full democratization is argued not to represent an optimal choice for the oil-rich...

Profit Sharing under the Threat of Nationalization AgEcon
Di Corato, Luca.
A multinational corporation engages in foreign direct investment for the extraction of a natural resource in a developing country. The corporation bears the initial investment and earns as a return a share of the profits. The host country provides access and guarantees conditions of operation. Since the investment is totally sunk, the corporation must account in its plan not only for uncertainty in market conditions but also for the threat of nationalization. In a real options framework, where the government holds an American call option on nationalization, we show under which conditions a Nash bargaining leads to a profit distribution maximizing the joint venture surplus. We find that the threat of nationalization does not affect the investment threshold...

Profit Sharing under the Threat of Nationalization AgEcon
Di Corato, Luca.
A government bargains a mutually convenient agreement with a multinational corporation to extract a natural resource. The corporation bears the initial investment and earns as a return a share on the profits. The host country provides access and guarantee conditions of operation. Being the investment totally sunk, the corporation must account in its plan not only for uncertainty on market conditions but also for the threat of nationalization. In a real options framework where the government holds an American call option on nationalization we show under which conditions a Nash bargaining is feasible and leads to attain a cooperative agreement maximizing the joint venture surplus. We find that the threat of nationalization does not affect the investment time...

Sustainable financing of protected areas in Cambodia: Phnom Aural and Phnom Samkos wildlife sanctuaries AgEcon
Grieg-Gran, Maryanne; de la Harpe, Derek; McGinley, John; MacGregor, James; Bond, Ivan.
In order to increase protected area revenue, and as part of a drive for national economic development, the Cambodian government is starting to issue economic concessions in 'sustainable development zones' of of protected areas. The Phnom Aural and Phnom Samkos wildlife sanctuaries cover nearly 600,000 ha and are important for biodiversity conservation and environmental services. They are home to about 30,000 people who rely on subsistence agriculture, cattle raising, and collection of non-timber forest products for their livelihoods. Under the Cardamom Mountains Wildlife Sanctuaries Project, a joint project of the Cambodian Ministry of Environment and Fauna and Flora International, zoning plans have been developed for both sanctuaries through participatory...
