Última Accounting for Depletion of Oil and Gas Resources in Malaysia AgEcon Othman, Jamal; Jafari, Yaghoob. This paper provides an assessment of the changes in the availability of oil and gas resources in Malaysia. The physical and monetary balance sheets for crude oil and natural gas for the period 2000- 2007 was constructed. The net present value of expected future incomes to reflect the value of resource change was calculated based on a physical extraction and a resource rent scenario. Resource rent is gross operating surplus less the estimated user cost of produced capital in the crude oil and natural gas extraction industry. We obtained the gross operating surplus by subtracting the value of consumption of employees and net taxes on production cost from the value added of petroleum domestic products. Our findings noted serious reduction of oil reserves from...

Ano: 2011 URL: http://purl.umn.edu/100690 On the Green Side of Trade Competitiveness? Environmental Policies and Innovation in the EU AgEcon Valeria, Costantini; Mazzanti, Massimiliano. This paper aims to explore how the competitiveness of the EU economy, here captured by export dynamics over the medium run (1996-2007), has been affected by environmental regulation both on the public and private sector side. The strong and weak versions of the Porter hypothesis are tested by specifying the export dynamics of five aggregated manufacturing sectors classified by their technological or environmental content using a dynamic panel data estimator applied to a theoretically-based gravity model. When testing the strong version on export performances of manufacturing sectors, the overall effect of environmental policies does not conflict with export competitiveness. When testing the weak version using export flows of environmental goods,...

Ano: 2010 URL: http://purl.umn.edu/92910 Application of a Spatial Water Model in a Chinese Watershed AgEcon Fang, Lan; Nuppenau, Ernst-August. China’'s fast growing economy has brought some environmental problems, especially in water administration. Inefficiencies in irrigation activities have created severe negative effects to the environment of rural communities, and the more serious water shortages hamper food production, too. Major questions at hand are, how to improve water use efficiency, to reduce negative external effects, to optimize water allocation in agriculture, to invest in water saving technologies, and to assure more water for high value added agriculture. This paper investigates the impacts of irrigation technologies and investments in water saving on the rural economy and the environment. By taking into account individual farmers' inclination to adopt modern water-saving...

The dispute between the US and EU over GM foods at the WTO is examined in terms of the issues it raises about protectionism, environmental protection and precaution. The issue of whether GM, GM Derived and Non-GM foods are equivalent to each other is examined using data from a national choice modelling study in the UK. These categories of food are critical since they underpin the EU's new food labelling regime which it hoped would defuse the WTO dispute. The results are analysed using a Bayesian mixed logit model which allows greater flexibility in the modelling of preference distributions than that allowed through classical estimation. The Bayesian approach allows the use of censored normal and Johnson's SB distributions which can accommodate a bounded...

Ano: 2006 URL: http://purl.umn.edu/25503 Climate Change Adaptation, Development, and International Financial Support: Lessons from EU Pre-Accession and Solidarity Funds AgEcon Przyluski, Valentin; Hallegatte, Stephane. Funding adaptation requires adequate governance and there are different ways to organise and channel the funds to where it is most efficient and most necessary. This paper investigates this issue and studies the practical implementation of a development under conditionality, namely adaptation-development, and its requirement in terms of financing architecture. To contribute to this research, it looks at similar problems that have been met in the past, namely the European funding programs for Eastern Europe countries that were candidates to adhesion, and European internal structural and cohesion funds. These funding examples provide a pertinent analogy for the adaptation problem, and most issues in adaptation finance have also been met in these funds...

This study compares an ordered probit model and a Tobit model with selection to take into account both true zero and protest zero bids while estimating the willingness to pay (WTP) for conservation easements in Macon County, NC. By comparing the two models, the ordered/unordered selection issue of the protest responses is analyzed to demonstrate how the treatment of protest responses can significantly influence WTP models. Both models consistently show that income and knowledge are positive and significant factors, while distance to poorer quality streams and duration of residency are negative and significant factors on WTP.

Ano: 2008 URL: http://purl.umn.edu/45524 Adaptation approaches to climate change in China: An operational framework AgEcon Jiahua, Pan; Yan, Zheng; Markandya, Anil. Climate change poses great risks for China, which makes adaptation an essential response. However, adaptation planning and implementation are still at a preliminary stage with respect to the theoretical framework and methodology. This article focuses on the status, problems and basic needs as regards adaptation to climate change, and outlines the operational framework that the government is seeking to pursue for China’s adapting to climate change. The conclusion is that, to satisfy the basic needs of development, it is necessary to clarify development-oriented and incremental adaptation. Furthermore measures to enhance adaptive capacity can be classified as infrastructure-based, technology-based and institutional. Lastly the authors stress the importance...

The new model of rural development, based on the recognition of the economic, social and environmental function of the European agriculture, mainly headed to make strategies of intervention concerning about, from one side, the competitive ability of the agricultural and agro-industrial enterprises, and, from the other, the increasing of the economic, human, environmental and historical-cultural resources. In such context the multi-functional role of agriculture becomes central and the agricultural operators have to adapt themselves to items (the territories, the rural societies, the consumers, etc.) and to different prescriptions related to demands linked up with the productivity and/or the territory (defence of the ground, of the landscape, of the...

Ano: 2005 URL: http://purl.umn.edu/24486 Economic Growth and the Environment with Clean and Dirty Consumption AgEcon Orecchia, Carlo; Tessitore, Maria Elisabetta. This paper aims to verify the existence of the Environmental Kuznets Curve (EKC) or inverted U-shaped relationship between economic growth and environmental degradation in the context of endogenous growth. An important feature of this study is that the EKC is examined in the presence of pollution as a by product of consumption activities; also, pollution is a stock variable rather than a flow and tends to accumulate over time. In order to highlight the role of consumption on the environment, consumers do not consider directly pollution in the maximization problem and are assumed to choose between two different consumption types, characterized by a different impact on the environment (i.e. dirty and clean consumption). We find that substitution of dirty...

Ano: 2011 URL: http://purl.umn.edu/115734 Core Issues in the Economics of Biodiversity Conservation AgEcon Tisdell, Clement A.. Critically reviews the following core issues in the economics of biodiversity conservation: reliance on the stated preferences of individuals as a guide to biodiversity conservation, the relevance of the phylogenetic similarity principle (and other attributes of organisms) for the survival of species; the implications of the Noah’s ark problem for selecting features of biodiversity to be saved and the difficulties raised by criteria based on safe minimum populations of species or on minimum environmental standards; the extent to which the precautionary principle can be rationally used to support the conservation of biodiversity; the impact of market extensions and globalization, as well as market and other institutional failures, on biodiversity loss; the...

Ano: 2010 URL: http://purl.umn.edu/92772 The Environment and Directed Technical Change: Comment AgEcon Hourcade, Jean-Charles; Pottier, Antonin; Espagne, Etienne. This paper discusses the growth model with environmental constraints recently presented in (Acemoglu et al., 2011) which focuses on the redirection of technical change by climate policies with research subsidies and a carbon tax. First, Acemoglu et al.'s model and chosen parameters yield numerical results that do not support the conclusion that ambitious climate policies can be conducted “without sacrificing (much or any) long-run growth”. Second, they select unrealistic key parameters for carbon sinks and elasticity of substitution. We find that more realistic parameters lead to very different results. Third, the model leads to an unrealistic conclusion when used to analyse endogenous growth, suggesting specification problems.

Ano: 2011 URL: http://purl.umn.edu/120046 Equity judgments and context dependence: Knowledge, efficiency and incentives AgEcon Schilizzi, Steven. Distributional equity concerns are often at least as important as economic efficiency and ecological sustainability in environmental and natural resource management policies. Until recently, however, economists have shied away from tackling equity issues, primarily because equity appeared as a slippery concept, varying across people and circumstances. This study takes this context-dependence of equity judgments as a starting point and shows that such dependence, far from being random, is systematic. A series of controlled laboratory treatments with University students were designed to investigate the role on distributional equity judgments of such context factors as knowledge of one’s position in society, how the existence of equity-efficiency tradeoffs...

Ano: 2006 URL: http://purl.umn.edu/60888 Forest Certification: Toward Common Standards? AgEcon Fischer, Carolyn; Aguilar, Francisco X.; Jawahar, Puja; Sedjo, Roger A.. The forestry industry provides a good illustration of the active roles that industry associations, environmental nongovernmental organizations (NGOs), national governments, and international organizations can play in developing and promoting codes of conduct that are formally sanctioned and certified. It also reflects some of the challenges of disseminating codes of conduct in developing countries and ensuring market benefits from certification. We describe the emergence of forest certification standards, outline current certification schemes, and discuss the role of major corporations in creating demand for certified products. We also discuss the limited success of certification and some of the obstacles to its adoption in developing countries. The...

Ano: 2005 URL: http://purl.umn.edu/10838 Impacts of Border Carbon Adjustments on China’s Sectoral Emissions: Simulations with a Dynamic Computable General Equilibrium Model AgEcon Bao, Qin; Tang, Ling; Zhang, ZhongXiang; Qiao, Han; Wang, Shouyang. Carbon-based border tax adjustments (BTAs) have recently been proposed by some OECD countries to level the carbon playing field and target major emerging economies. This paper applies a multi-sector dynamic computable general equilibrium (CGE) model to estimate the impacts of the BTAs implemented by US and EU on China’s sectoral carbon emissions. The results indicate that BTAs will cut down export prices and transmit the effects to the whole economy, reducing sectoral output-demands from both supply side and demand side. On the supply side, sectors might substitute away from exporting toward domestic market, increasing sectoral supply; while on the demand side, the domestic income may be strikingly cut down due to the decrease in export price, decreasing...

Ano: 2011 URL: http://purl.umn.edu/120044 Evolution of Crop-dairy Production Systems in South India from 1971 to 2002 AgEcon Yaguchi, Yue; Kajisa, Kei. It is widely believed that not only a Green Revolution in a crop sector but also a White Revolution in a dairy sector has generated the great momentum of agricultural development in India since the late 1960s. However, due to the dominance of sector-specific analyses, the importance of the interaction between these two sectors has been neglected in the existing literature. The interaction is important in that the dairy sector provides manure to crop production while the crop sector supplies fodder to the dairy. Using household data collected in Tamil Nadu, India for three decades from 1971, we show the increase of fodder production as a byproduct of Green Revolution in 1970s enabled subsequent White Revolution in 1980s and the byproduct of the White...

We employ a two-sector heterogeneous firms model in the presence of endogenous innovation and environmental constraints. We perform simple numerical simulations concerning the implication of a stringent environmental policy and trade cost differences between dirty and clean inputs. Our objective is to highlight the effects of these policy proposals on the process innovation, trade pattern, and productivity dynamics.

Ano: 2011 URL: http://purl.umn.edu/103478 Emissions Trends and Labour Productivity Dynamics Sector Analyses of De-coupling/Recoupling on a 1990-2005 Namea AgEcon Marin, Giovanni; Mazzanti, Massimiliano. This paper provides new empirical evidence on Environmental Kuznets Curves (EKC) for greenhouse gases (GHGs) and air pollutants at sector level. A panel dataset based on the Italian NAMEA over 1990-2005 is analysed, focusing on both emission efficiency (EKC model) and total emissions (IPAT model). Results show that looking at sector evidence, both decoupling and also eventually re-coupling trends could emerge along the path of economic development. CH4 is moderately decreasing in recent years, but being a minor gas compared to CO2, the overall performance on GHGs is not compliant with Kyoto targets, which do not appear to have generated a structural break in the dynamics at least for GHGs. SOx and NOx show decreasing patterns, though the shape is affected...

As policy makers, taxpayers and consumers are willing to know the actual contribution of farming to natural and social environment, sustainability and sustainable development arose as key issues in public debates. Sustainability is a multifaceted concept that includes environmental, economic and social objectives and policy makers need information to take effective decisions. Analysts should rank decisional units according to sustainability criteria and should offer to policy makers more and more insights on the different points of view behind the three dimensions of sustainability. Within the current FADN database sustainability indicators have been identified. In some cases estimations have been necessary and in some other cases thanks to allocation of...
