should reference alternatives in pivot design sc surveys be treated differently analysts are increasingly making use of pivot style stated choice sc data in the estimation of choice models these datasets often contain a reference alternative whose attributes remain invariant across replications for the same respondent this paper presents evidence to suggest that respondents react differently to the attributes of these reference alternatives and those of purely hypothetical alternatives while some such evidence has been reported in the existing literature this paper goes further and details a number of different departures from a common treatment of the two types of alternatives relating both to the observed part of utility and the error term

valuing the attributes of renewable energy investments increasing the proportion of power derived from renewable energy sources is becoming an increasingly important part of many countries s strategies to achieve reductions in greenhouse gas emissions however renewable energy investments can often have external costs and benefits which need to be taken into account if socially optimal investments are to be made this paper attempts to estimate the magnitude of these external costs and benefits for the case of renewable technologies in scotland a country which has set particularly ambitious targets for expanding renewable energy the external effects we consider are those on landscape quality wildlife and air quality we also consider the welfare implications of different investment strategies for employment and electricity prices the methodology used to do this is the choice experiment technique renewable technologies considered include hydro on shore and off shore wind power and biomass welfare changes for different combinations of impacts associated with different investment strategies are estimated we also test for differences in preferences towards these impacts between urban and rural communities and between high and low income households

assessment of public acceptance and willingness to pay for renewable energy sources in crete abstract the aim of this study is to analyse and to evaluate the citizens public acceptance and willingness to pay wtp for renewable energy sources res in crete for this purpose a contingent valuation study was conducted using a double bound dichotomous choice format to elicit people s wtp and factors affecting it residents of 1440 households all over crete were interviewed face to face major conclusions can be used as a basis for sustainable energy planning for policies and the formulation of awareness campaigns and for res investment programs and projects in order to prepare implementation conditions and enhance public acceptance of renewable energy investments and programmes mean wtp per household was found to be 16 33 to be paid quarterly as an additional charge on the electricity bill larger willingness to pay was reported by those with high family income and residence size those having a higher level of energy information and awareness concerning climatic change those who have invested in some energy saving measures and those who suffer from more electricity shortages than others

a target group specific approach to green power retailing students as consumers of renewable energy an extensive body of literature exists on the obstacles that have to be overcome in green power retailing in this article target group specific marketing is evaluated as a strategy to increase the share of residential customers of green power a sample of students in the city of freiburg germany was interviewed in order to assess their awareness of environmental issues their willingness to change to green power products and to better understand individual hindrances in changing the power supplier the analysis shows that students are highly positive towards green power products but for several reasons difficult to reach in marketing campaigns aspects to be considered in addressing this consumer group include the students particular expectations towards green products their living conditions price sensitivity and their perception of the relative effort involved in changing the power provider

benefit estimates for landscape improvements sequential bayesian design and respondents rationality in a choice experiment a multi attribute stated preference approach is used to value low and high impact actions on four major landscape components addressed by the rural environment protection scheme in ireland several methodological issues are addressed the use of prior beliefs on the relative magnitudes of parameters standardized description of different levels of landscape improvements via image manipulation software adoption of efficiency increasing sequential experimental design and sensitivity of benefit estimates to inclusion of responses from irrational respondents results suggest that bayesian design updating delivers significant efficiency gains without loss in respondent efficiency and estimates are upward biased when irrational respondents are included

social demand for electricity from forest biomass in spain does payment periodicity affect the willingness to pay in this article we analyze social preferences for a partial substitution programme of electricity generated by conventional energy sources for energy generated from a local renewable energy source such as forest biomass this analysis sets arguments in favour of accelerating the introduction of this renewable technology in the spanish electricity system simultaneously two methodological goals concerning the contingent valuation method are discussed in the first one we analyze if there are statistical differences in the willingness to pay wtp when a single or a double bounded format is employed to ask the valuation question results show that wtp estimates from single and double bounded significantly differ in the second one we analyze the effect of the periodicity of the payment vehicle on the estimates of welfare change the timeframe specification of the payment vehicle has been scarcely studied and this fact constitutes the main contribution of this paper to the specialized literature results show that periodicity influences upon the probability to favour the proposed change the periodicity does not affect to the mean wtp obtained in the single bounded format but there are statistical differences in the double bounded format these results might be explained by the presence of yea saying and payment scale bias

decoupling between human development and energy consumption within footprint accounts abstract historically the growth of energy consumption has fuelled human development but this approach is no longer socially and environmentally sustainable recent analyses suggest that some individual countries have responded to this issue successfully by decoupling total primary energy supply from human development increase however globalisation and international trade have allowed high income countries to outsource industrial production to lower income countries thereby increasingly relying on foreign energy use to satisfy their own consumption of goods and services accounting for the import of embodied energy in goods and services this study proposes an alternative estimation of the decoupling index based on the total primary energy footprint rather than total primary energy supply an analysis of 126 countries over the years 2000 2014 demonstrates that previous studies based on energy supply highly overestimated decoupling footprint based results on the other hand show an overall decrease of the decoupling index for most countries 93 out of 126 there is a reduction of the number of both absolutely decoupled countries from 40 to 27 and relatively decoupled countries from 29 to 17 and an increase of coupled countries from 55 to 80 furthermore the study shows that decoupling is not a phenomenon characterising only high income countries due to improvements in energy efficiency but is also occurring in countries with low human development index and low energy consumption finally six exemplary countries have been identified which were able to maintain a continuous decoupling trend from these exemplary countries lessons have been identified in order to boost the necessary global decoupling of energy consumption and achieved welfare

consumer demand for green power and energy efficiency abstract this article examines reported willingness to pay for electric utility investments in renewable energy and energy efficiency resources using the results of deliberative polls conducted by electric utilities in texas 1 age education and salary tend to affect reported willingness to pay for utility investments in these resources intensive exposure to information about energy resource issues led to an increase in the number of respondents interested in paying a modest premium to support investments in both renewable energy resources and energy efficiency however average reported premiums actually declined following the polls as very high outlier responses moved to more reasonable values following the polls these results support the contention that informed dialogue about energy alternatives will result in broader interest in providing a modest level of support for these resources

incorporating discontinuous preferences into the analysis of discrete choice experiments data from a discrete choice experiment on improvements of rural landscape attributes are used to investigate the implications of discontinuous preferences on willingness to pay estimates using a multinomial error component logit model we explore differences in scale and unexplained variance between respondents with discontinuous and continuous preferences and condition taste intensities on whether or not each attribute was considered by the respondent during the evaluation of alternatives results suggest that significant improvements in model performance can be achieved when discontinuous preferences are accommodated in the econometric specification and that the magnitude and robustness of the willingness to pay estimates are sensitive to discontinuous preferences

renegotiation and information revelation over time the case of optimal labor contracts the paper analyzes the issue of commitment in grossman and hart s model of optimal labor contracts under asymmetric information about firm profitability we extend their framework by allowing employment to vary over time at equidistant intervals when both parties can precommit ex ante not to renegotiate the contract this replicates the grossman hart outcome each subperiod when precommitment is not possible information revealed through the contract can create pareto improving renegotiation opportunities and the issue of optimal information revelation arises the paper analyzes the impact of ex post pareto improving renegotiations on the optimal contract

citizen versus consumer challenges in the uk green power market abstract this paper investigates the potential advantages and disadvantages of green power products as opposed to the traditional fossil fuel levy which was the uk s chosen tax regime as a means of developing renewable energy in the uk willingness to pay for electricity generated from renewables is investigated results indicate that willingness to pay varies with social status and income however results demonstrate that there is a significant minority in full support of some sort of fiscal initiative electricity generated from renewables is a concept supported by the majority however given the stated willingness to pay it is unlikely that any new renewable capacity will result from green tariff schemes in the near term it is concluded that the green citizen must continue to co exist with the green power purchaser if the uk is to make any significant improvement in the contribution of renewable energy to electricity demand the authors would like to acknowledge the support of irene lorenzoni and jane powell of the centre for social and economic research on the global environment university of east anglia leicester energy efficiency advice centre and leicester energy agency

using contingent valuation to explore willingness to pay for renewable energy a comparison of collective and voluntary payment vehicles abstract this study uses a split sample dichotomous choice contingent valuation survey of 1574 u s residents to explore willingness to pay wtp for renewable energy under collective and voluntary payment vehicles and under government and private provision of the good we also evaluate the impact of participation expectations on stated wtp we find some evidence that when confronted with a collective payment mechanism respondents state a somewhat higher wtp than when voluntary payment mechanisms are used similarly private provision of the good elicits a somewhat higher wtp than does government provision we also find that contingent valuation responses are strongly correlated with expectations for the wtp of others our results shed light on strategic response behavior and the incentive compatibility of different cv designs and offer practical insight into u s household preferences for how to support renewable energy

energy use and output growth in canada a multivariate cointegration analysis using a neo classical one sector aggregate production technology where capital labor and energy are treated as separate inputs this paper develops a vector error correction vec model to test for the existence and direction of causality between output growth and energy use in canada using the johansen cointegration technique the empirical findings indicate that the long run movements of output labor capital and energy use in canada are related by two cointegrating vectors then using a vec specification the short run dynamics of the variables indicate that granger causality is running in both directions between output growth and energy use hence an important policy implication of the analysis is that energy can be considered as a limiting factor to output growth in canada

lexicographic preferences in contingent valuation a theoretical framework with illustrations this paper considers some implications of l ordering an incommensurable preference model proposed in earlier cvliterature the structure and existence of inverse demand functions is shown to be a function of three elements the relationship between goods and wants wta wtp formats and the endowment of the good in a many to many relationship uncompensated and even compensated inverse demand functions may exist whereas a one to one relationship implicitly assumed in earlier literature does not necessarily produce either an illustration is provided in support of the theoretical framework especially the hypothesis that one to one relationship and high share of cv responses revealing lexicographic preferences are correlated

economic development and the energy intensity of human well being evidence from the gcc countries abstract this paper empirically investigates the effect of economic development on the energy intensity of human well being eiwb in the gulf cooperation council gcc during the period 1995 2012 we employ a time series cross sectional prais winsten regression model with panel corrected standard errors pcse we conclude that economic development has had a significant positive impact on eiwb during the period 1995 2012 the results indicate that the stress on the environment had increased in a noticeable manner from 1995 until 2006 however over the period 2007 2012 the stress went back to the level observed in 1995 this observation is unfortunate from the perspective sustainable economics

can renewable energy be financed with higher electricity prices evidence from a spanish region abstract in this paper we estimate the willingness to pay for mix of renewable sources of electric power by means of a discrete choice experiment survey conducted in spain in 2010 two main categories of power supply attributes are explored source of renewable power wind solar and biomass and the origin of such power the findings suggest that most consumers are not willing to pay a premium for increases in the shares of renewable in their electricity mix for two of the three renewable sources considered wind and biomass an increase of the renewable mix would require a discount instead we record positive willing to pay for increases in the share of both solar power and locally generated power however preferences for types of renewable solar and wind are found to be heterogeneous by classifying respondents in two groups according to the implied importance of the share of renewable sources in their power mix we identify a market segment consisting of 20 of respondents that could promote renewable energy in the absence of subsidies this is because such a segment shows willingness to pay higher than the current feed in tariffs

bayesian conjoint choice designs for measuring willingness to pay in this paper we propose a new criterion for selecting efficient conjoint choice designs when the interest is in quantifying willingness to pay wtp the new criterion which we call the wtp optimality criterion is based on the c optimality criterion which is often used in the optimal experimental design literature we use a simulation study to evaluate the designs generated using the wtp optimality criterion and discuss the design of a real life conjoint experiment from the literature the results show that the new criterion leads to designs that yield more precise estimates of the wtp than bayesian d optimal conjoint choice designs which are increasingly being seen as the state of the art designs for conjoint choice studies and to a substantial reduction in the occurrence of unrealistically high wtp estimates

valuing a wind farm construction a contingent valuation study in greece abstract our analysis is based on data from a double bounded dichotomous choice contingent valuation study implemented to elicit public attitudes towards renewable energy generation and their willingness to pay for the construction of a wind farm in the area of messanagros in the island of rhodes greece results indicate that there are significant positive values deriving from the proposed project respondents report a mean willingness to pay a premium in their bi monthly electric bills of 8 86 for the sole purpose of the construction of the wind farm the estimated economic benefits to the local population are weighed against the investment cost in a cost benefit analysis to inform policy making and implications for eu energy policy are provided

us consumers willingness to pay for green electricity abstract we analyze us consumers demand for environmental attributes of deregulated residential electricity services using results from a survey designed to elicit consumers willingness to pay for such attributes and using results from a hedonic analysis of actual price premiums charged for green electricity in several deregulated markets survey results suggest that many population segments are willing to pay for decreased air emissions even if there is no alteration in fuel source furthermore several groups are willing to pay significantly more when emissions reductions stem from increased reliance upon renewable fuels the hedonic analysis suggests that several product features not considered in the survey help explain real price premiums including fuel mix from newly created renewable generation capacity green e certification brand name and state of offer while survey and hedonic results are not easily compared due to limitations of the survey both point to similar values for key environmental attributes though the survey results are likely to overstate actual willingness to pay in sum the results suggest that consumer driven purchases can in part support the future of renewable generation capacity in the united states though reliance upon other policy alternatives may be needed if energy prices spike

spatial effects of economic performance on the carbon intensity of human well being the environmental kuznets curve in chinese provinces abstract this study analyzes the interdependent relationship between economic development and environmental and human well being in china we evaluate panel data of the carbon intensity of human well being ciwb to measure environmental sustainability and human well being for 30 chinese provinces from 1995 to 2016 we then employ a spatial model to test the environmental kuznets curve the ciwb is an important indicator that incorporates the environmental social and economic dimensions of sustainability the coefficients of gdp squared gdp and cubic gdp are 1 043 0 123 and 0 0045 respectively indicating that the relationship between ciwb and economic growth is an inverted n shape in other words as gdp increases from low to high the ciwb first decreases then increases for a long period until it reaches a turning point and declines thereafter gdp per capita at the two turning points are 850 yuan and 110 000 yuan respectively in the long run economic growth is expected to have a positive effect on sustainable development however currently environmental policies are needed to offset unintended environmental harm analysis of spatial evolution and multiplier spatial effects show that spatial disparity and clustering exist simultaneously this suggests that overall planning for the big picture and cooperative development between adjacent provinces could help to handle regional environmental problems

using conjoint analysis to quantify public preferences over the environmental impacts of wind farms an example from spain this paper focuses on the effect on people s utility of the potential environmental impacts of wind farm developments we report on research designed to provide insight into their preferences and we show how two alternative choice modelling techniques can be used to estimate them our results show that significant social costs in the form of environmental impacts can be associated with wind farm developments as relative environmental values are revealed by these methods it would be possible to develop wind farms in such a way that minimises the total social costs of the investment and which maximises its net benefits

exploring the bi directional long run relationship between energy consumption and life quality abstract this study aims at investigating the bi directional long run relationship for the period of 1990 2009 between energy consumption and life quality in 198 countries categorized by income level to achieve this goal the canonical cointegrating regression ccr was utilized the results revealed that energy consumption improves the life quality of 70 of the countries despite their different incomes the study s results unlike all other previous studies also revealed that the life quality indicators also increase energy consumption a phenomenon that appears to be true in 65 of the countries despite the fact that energy consumption plays an important role in achieving a better life quality the world still depends on fossil fuels which represent 81 of total energy consumption therefore it is suggested that these countries should rationalize their fossil fuel energy consumption by increasing the role of renewable energy and increasing their energy saving to improve life quality without causing any damage to the environment

ecosystems contingent valuation and ethics the case of wetland re creation this paper addresses a current issue in environmental valuation namely the extent to which environmental preferences depart from the usual economic paradigm to incorporate some lexicographic elements after a theoretical discussion the paper reviews attempts to explore this question empirically by supplementing contingent valuation analyses with an exploration of the motives behind willingness to pay responses including zero bids and refusals to answer this is followed by the presentation of new evidence investigating respondents willingness to pay for the creation of a wetland taken from 713 personal interviews of the british public 2000 elsevier science b v all rights reserved

landscape externalities from onshore wind power the expansion of renewable energy is a central element of the german federal government s climate and energy policy the target for 2020 is to produce 30 of the electricity from renewable energies wind power has been selected to be a major contributor to this change replacing old wind turbines by modern ones and building new turbines on land will be crucial in meeting this target however the expansion of onshore wind power is not universally accepted in several regions of germany residents are protesting against setting up new wind turbines to determine the negative effects two choice experiments were applied in westsachsen and nordhessen germany in both regions the externalities of wind power generation until 2020 based on today s state of technology were measured the results show that negative landscape externalities would result from expanding wind power generation using latent class models three different groups of respondents experiencing different degrees of externalities were identified

greenhouse gas emissions and subjective well being an analysis of swedish households abstract in the contemporary discussion on society s transformation towards long term climate targets it is often implicitly assumed that behavioral changes unlike technological changes would lead to reductions in human well being however this assumption has been questioned by researchers who instead argue that people may live better lives by consuming less and reduce their environmental impact in the process in this study we explore the relationship between greenhouse gas emissions and subjective well being using a sample of 1000 swedish respondents our results show that there is no strong link between an individual s emissions and subjective wellbeing we also analyze the relationship between specific emission intensive activities and subjective well being and find that none of the activities examined correlates with subjective well being finally we explore a hypothesis put forward in the literature suggesting that a poor work life balance long commuting distances and materialistic values may decrease individuals subjective well being and increase greenhouse gas emissions our results indicate that materialistic values do correlate with lower levels of well being and to some extent also with higher greenhouse gas emissions

preferences for site and environmental functions when selecting forthcoming national parks abstract a political decision to establish the first ever national parks in denmark allowed us to examine if people hold preferences regarding which site to be designated as national park separate from the preferences for its environmental functions to this end we designed a choice experiment representing the national park alternatives by the possible site and the possible improvements in environmental functions results revealed that respondents have strong preferences for the establishment of a national park per se furthermore there are significant differences in taste parameters for the different sites which cannot be explained by respondents valuing the different functions differently across sites instead we explain the results with differences in regional and cultural preferences we also performed a balanced split sample test of anchoring effects and found clear evidence of this we included a zero bidder screening question prior to the choice set part of the survey instrument to improve wtp estimation

does increasing energy or electricity consumption improve quality of life in industrial nations among the world s nations per capita energy and electricity consumption is highly correlated with diverse indicators of quality of life this is often interpreted to mean that additional energy and electricity consumption causes improvements in life quality prior analyses of cross sectional data question this interpretation for industrial nations that already have high per capita energy consumption the present analysis with longitudinal data shows that among industrial nations increases in per capita energy and electricity consumption over the past three decades are not associated with corresponding improvements in quality of life

valuation for renewable energy a comparative review abstract environmental cost benefit analysis is applied for the evaluation of renewable energy projects since some benefits and costs do not have monetary values economic valuation techniques are applied to estimate them this paper reviews the literature on the valuation evaluation of renewable energy resources and summarizes the methods used in them it discerns four main streams of valuation in renewable energy the first is economic welfare oriented and comprises stated and revealed preference methods the second is the financial option analysis with a financial background the third is emergy analysis which is mostly an ecological engineering based method with capable economic links and the fourth is again economic but not welfare based the paper discusses the main directions discerned in these studies and recognizes first that proper valuation takes place only in the first method while the other methods describe only evaluation procedures and second that there is a research gap that has yet to be filled in as compared to other areas of environmental resource and energy economics

bridging the energy divide and securing higher collective well being in a climate constrained world abstract despite the impressive gains in available energy over the last 200 years the associated benefits remain unevenly distributed bridging this divide only adds to the already daunting challenge of securing climate stabilization in fact efforts towards the former are more likely to conflict with the latter to be able to address this dilemma the relationship between energy consumption and human well being beyond its economic dimension needs to be better understood this paper aims to contribute to the emerging knowledge base by examining this relationship using a proxy for human well being that also considers its environmental and social dimensions the ultimate goal of this paper is to investigate the potential incompatibility between efforts towards the achievement of higher collective well being and those associated with climate stabilization to this end it provides estimates of the additional energy needed and its associated carbon emissions under different climate scenarios and compares them with existing carbon budgets results indicate that even if new climate policies were adopted emissions associated with higher well being in all regions where improvements are needed could still reach up to one and a half times estimated 2 c budgets and even more so for lower temperature increase targets

monitoring choice task attribute attendance in nonmarket valuation of multiple park management services does it matter land management in alpine parks provides multifunctional services to separate groups of users choice experiments can be used to derive estimates of value for different management attri butes however little research has been conducted on how frequently respondents ignore attributes used to describe policy management scenarios we fill this gap using an approach that identifies and compares both serial and choice task attribute nonattendance addressing five different visitor types our results indicate that accounting for choice task nonatten dance significantly improves model fit and yield estimates of marginal willingness to pay with a more plausible pattern of signs and greater efficiency jel q24 q51 i introduction the effects of park management policies on outdoor recreation are increasingly coming under public scrutiny alpine park land is among the most valuable land in terms of outdoor recreation park manage ment decisions are often controversial be cause of differences between objectives pursued by conservationists and the tourist industry parkland management agencies find it increasingly difficult to fund all the services needed to facilitate the ever broad ening variety of outdoor recreation activi ties this is further exacerbated by the increasing expectations for high quality recreational experiences by a population of recreationists with a heightened sensitivity to environmental and conservation issues such a situation widens the scope for multiattribute nonmarket valuation meth ods especially for those methods capable of capturing and modeling the preferences of heterogeneous visitors who seek to pursue a variety of activities in the land under study our research reports the results of a study designed to address attribute nonattendance henceforth abbreviated as an a which despite being quite a common decision heuristic has only recently begun to be explored by analysts with this decision heuristic respondents ignore some of the described attributes in their evaluation of alternatives within a given choice task they hence act as if a zero weight were assigned to the ignored attributes in the utility of the respective alternatives we study this issue by using a well known statistical model of discrete choice the multinomial logit mnl model this random utility model is often used for the purpose of multi attribute nonmarket valuation but the effects of accounting for an a are still rela tively unexplored information on an a is commonly collected by questioning each respondent at the end of the sequence of choice tasks respondents are asked to list those attributes that they feel they have

energy security measurement a sustainable approach abstract the main objective of this paper is to define new energy security indicator with the long term sustainability and to test it in a sample of 28 european union countries for the period 1990 2012 as well as to determine the level of impact of six different indicators on energy security the previous methodologies for measuring of energy security have been mainly focused on security of supply while not taking into account environmental indicators and the social component the newly proposed indicator energy security index differs from the existing measuring methods precisely in a way that it includes environmental and social aspects energy security index recorded a decline in values in most countries in the period 1990 2000 in the period 2000 2008 the values became positive and after 2008 some countries reported again gradual deterioration the index value varies by year and the biggest positive changes were recorded in the case of the netherlands slovenia and spain the four economically strongest eu countries the united kingdom france germany and italy recorded significantly less fluctuations in energy security over 23 years compared to other countries the data for france and denmark show that an increased share of energy from nuclear and renewable sources can compensate even increased energy import dependence the assessment of impact of individual indicators on energy security index was conducted by using principal component analysis and showed that energy intensity gdp per capita and carbon intensity have the greatest impact the countries of the former eastern bloc are facing particular challenges of energy security which is primarily related to the rapid economic growth and at the same time a high degree of dependence on import of energy generating products in terms of energy security the most stable transition was reported in hungary and poland

rural versus urban preferences for renewable energy developments development of renewable energy resources such as wind farms and hydro electric schemes are being promoted as a new method of expanding and diversifying employment in rural areas however such energy projects are associated with a range of environmental impacts which might be detrimental to other economic activities such as those based on nature tourism the authors use a choice experiment to quantify peoples preferences over environmental and employment impacts that may result from the deployment of renewable energy projects in rural areas of scotland focussing in particular on any differences between the preferences of urban and rural dwellers and on heterogeneity within these groups rural and urban households are shown to have different welfare gains which are dependent on the type of renewable energy technology and on the scale of project under consideration
