Economic techniques to estimate the demand for sustainable products: a case study for fair trade and organic coffee in the United Kingdom

The hedonic approach is used in this paper to estimate how much is paid for the fair trade/organic characteristic of the coffee in the British market. This information is later combined with the Quantity Based Demand System (QBDS) model -developed by the authors- and the Almost Ideal Demand System (AIDS) (Deaton and Muellbauer, 1980) to completely determine the demand function for different coffees. The QBDS model is easier to handle and less data demanding than the AIDS model in this study. Resumen El presente artículo se basa en la utilización del método hedónico para la estimación de la cantidad que se paga por la característica de "Orgánico/Comercio Justo" del café en el mercado británico. La información obtenida se combina después con el modelo Sistema de Demanda Basado en Cantidades (QBDS) - desarrollado por los autores- y el Sistema de Demanda Casi Ideal (AIDS) (Deaton and Muellbauer, 1980) para determinar por completo la función de demanda de los diferentes tipos de café. El modelo QBDS es más sencillo en su utilización y necesita de menos datos que el modelo AIDS.

Identification of Options and Policy Instruments for the Internalisation of External Costs of Electricity Generation. Dissemination of External Costs of Electricity Supply Making Electricity External Costs Known to Policy-Makers MAXIMA

In the present paper, after reviewing the results of the ExternE project and its follow-up stages in the estimation of the external costs of electricity production, we look at the policy instruments for the internalisation of such costs. Emphasis is given to subsidies, such as feed-in tariffs, competitive bidding processes and tradable green certificates to stimulate the use of renewables in the production of electricity. When policy-makers are asked to choose the instrument(s) to internalise the externalities in the electricity production, they have to find a solution that gives the best outcome in terms of efficiency, cost minimisation, impact on the job market, security of energy supply, equity of the instrument, technological innovation, certainty of the level of the internalisation, and feasibility. The choice of the instrument will require some trade-offs among these criteria. Conjoint choice analysis can help in investigating how stakeholders and policy makers trade off the criteria when choosing a policy for the internalisation of the externalities. In this paper we present the first results of a questionnaire that employs conjoint choice questions to find out how policy makers and stakeholders of the electricity market trade off some socio-economic aspects in the selection of the policy instruments for the internalisation of the externalities. The results of this first set of interviews will be useful for further research.Policy instruments, ExternE, External costs, Electricity, Conjoint choice analysis

Rural Electrification Programmes in Kenya : Policy Conclusion from a Valuation Study

Developing countries have struggled with low electrification rates in the rural areas. This study investigates one major issue impeding the rural electrification programmes in rural Kenya: high connection payments. The paper uses estimates obtained from a stated preference study, namely a contingent valuation method completed in 2007, to examine the willingness to pay to connect to grid-electricity and photovoltaic services. Expanding rural electrification will need subsidies, but the study shows that some forms of subsidy are more effective than others. The key findings suggest that the government needs to reform the energy subsidies, increase market ownership and performance of private suppliers, establish financial schemes and create markets that vary according to social-economic and demographic groups.rural electrification; willingness to pay (wtp); affordability; sub-saharan africa; energy

How Substitutable is Natural Capital?

One of the recurring themes in the sustainability literature has been the legitimacy of using an economic framework to account for natural resources. This paper examines the potential for substituting between different inputs in the generation of income, where the inputs include natural resources such as land and energy resources. A nested CES production function is used to allow flexibility in the estimated elasticities of substitution. Also, with this specification, natural resources and other inputs are combined in different levels of the function, thus allowing for different levels of substitutability. Institutional and economic indicators are also incorporated in the production function estimated. Results show that the elasticities derived from functions involving land resources were generally around one or greater. Furthermore, changes in trade openness and private sector investment have a statistically significant and direct relationship with income generation. No statistically significant relationship between income and any of the institutional indicators was found.Wealth accounting, Natural resources, Nested CES production function

Climate Change and Its Socioeconomic Importance

Climate change has played an increasingly key role in recent years and is now one of the leading political priorities worldwide. This article illustrates the scope of the problem, its causes and its impacts, along with the possible solutions that are being considered on the international stage. The existing information regarding these topics is summarised, together with the associated costs and the scale of the effort required to tackle climate change. The article explains why climate change can be seen as a market failure, the importance of public policies to correct this problem and its impact on international trade. The last section considers the international debate taking place in the United Nations Conferences and the Kyoto Protocol as well as what is expected with respect to the future post-Kyoto negotiations.Climate change, policy

Impure Public Technologies and Environmental Policy

Analyses of public goods regularly address the case of pure public goods. However, a large number of (international) public goods exhibit characteristics of different degrees of publicness, i.e. they are impure public goods. In our analysis of transfers helping to overcome the inefficient provision of such goods, we therefore apply the Lancastrian characteristics approach. In contrast to the existing literature, we consider the case of a continuum of impure public goods. We employ the example of international conditional transfers targeting to overcome suboptimal low climate protection efforts by influencing the abatement technology choice of countries.Impure Public Goods, Lancastrian Characteristics Approach, Conditional Transfers, Ancillary Benefits of Climate Policy

Is the Value of Bioprospecting Contracts Too Low?

In order to regulate the proliferated bioprospecting and protect the biological diversity in the source countries, the Convention on Biological Diversity (CBD) established a legal framework for the reciprocal transfer of biological materials between the interested parties in bioprospecting activities, subject to the Prior Informed Content (PIC) principles and a set of mutually agreed items on equitable sharing of benefits (CBD 1992, Bhat 1999; Ten Kate and Laird 1999; Dedeurwaerdere 2005). Although interesting and valuable to the cause of conservation, there is a feeling that the ‘price’ being paid under these arrangements is too low. Somehow ecologists argue that, surely, these materials have a greater value than the few million dollars being paid to national conservation organizations for the protection of the areas where the material are located. In this paper we seek to understand better how a biodiversity resource’ use value in production is determined, and how the real value is obscured by the fact that the resource is largely open access. We attempt to analyse how special arrangements, set op top of a basic framework in which the resource open access is limited in what it can achieve and in the ‘price’ that will emerge from any transaction between the buyers of the rights and the sellers of the rights.Access and Benefit Sharing, Convention for Biological Diversity, Bioprospecting Contract, Genetic Resource, Open Access and Welfare Analysis

How substitutable is natural capital ?

One of the recurring themes in the sustainability literature has been the legitimacy of using an economic framework to account for natural resources. This paper examines the potential for substituting between different inputs in the generation of income, where the inputs include natural resources such as land and energy resources. A nested constant elasticity of substitution (CES) production function is used to allow flexibility in the estimated elasticities of substitution. Also, with this specification, natural resources and other inputs are combined in different levels of the function, thus allowing for different levels of substitutability. Institutional and economic indicators are also incorporated in the production function estimated. Results show that the elasticities derived from functions involving land resources were generally around one or greater, implying a fairly high degree of substitutability. Furthermore, changes in trade openness and private sector investment have a statistically significant and direct relationship with income generation. No statistically significant relationship between income and any of the institutional indicators was found.Economic Theory&Research,Inequality,Economic Growth,Banks&Banking Reform,Climate Change

Eastern Europe and the Former Soviet Union since the Fall of the Berlin Wall: Review of the Changes in the Environment and Natural Resources

This paper reviews the environmental record of the transition countries of Eastern Europe and Central Asia since the fall of the Berlin Wall, with a focus on areas of key concern to public policy at the present time. With the impacts of environment on public health being given the highest priority, we examined several associated health indicators at the national level, as well as looking at important environmental issues at the local level. In this respect, we focus on environmental problems related to air and water quality, land contamination, and solid waste management. Despite showing a highly differentiated performance across the region, the results suggest that inadequate environmental management seen in several of the transition countries in the past 20 years has put people’s health and livelihood under huge threats. Moreover, this paper looks at the development of policy responses and resources, i.e. environmental expenditures, in these countries, during the process of transiting from centrally planned economies to market-based one. Similarly, we identify various degrees of progress across the region. The findings reinforce the need for better coherence between national environmental expenditure and international environmental assistance, as well as the actual enforcement of national regulations and international agreements in those non-EU transition countries.Eastern Europe, Environmental Record, Public Health
