alternative value elicitation formats in contingent valuation mechanism design and convergent validity abstract to date much of the theoretical work on the incentive properties of contingent valuation surveys has focused on the oft recommended single binary choice sbc referendum format this work has identified conditions under which an sbc elicitation is incentive compatible and empirical evidence lends support to the predictive power of the theory nevertheless researchers and practitioners commonly use alternative elicitation formats and defend their design choices based on efficiency and other criteria in this study we demonstrate that it is possible to identify conditions under which alternative elicitation formats are incentive compatible using as examples open ended oe and payment card pc question formats we then implement theory informed value elicitations in the context of a flood control policy for new york city we fail to reject convergent validity in mean willingness to pay when comparing the theory driven oe format with sbc but reject convergent validity between the theory driven pc and sbc formats as an informative counterfactual we find that a standard oe elicitation congruent with prior work leads to significantly lower values and a lower proportion of respondents who view the elicitation as consequential

adoption of digital repositories for co2 emissions reduction the case of korea abstractthis study aims to estimate the potential economic benefits energy and co2 emissions reductions when using trusted third party digital repository ttpr services in one individual bank and within the banking industry in korea first the cost benefit and net benefit of using ttpr services in the banking industry are estimated second the net induced output effect is estimated third based on an environmentally extended input output analysis co2 emissions reduction was estimated as 1924 32 tons in 2009 and the energy consumption reduction as 640 70 toe fourth the total economic benefit which is the sum of the net induced output effect and economic value of co2 emissions reductions is approximately 11 04 million the findings demonstrate that energy consumption and co2 emissions reductions are meaningful enough to result in significant economic benefits therefore the korean government should promote the use of ttpr services in the entire industry

statistical efficiency of double bounded dichotomous choice contingent valuation the statistical efficiency of conventional dichotomous choice contingent valuation surveys can be improved by asking each respondent a second dichotomous choice question which depends on the response to the first question if the first response is yes the second bid is some amount greater than the first bid while if the first response is no the second bid is some amount smaller this double bounded approach is shown to be asymptotically more efficient than the conventional singlebounded approach using data from a survey of californians regarding their willingness to pay for wetlands in the san joaquin valley we show that in a finite sample the gain in efficiency can be very substantial

change in co2 emission and its transmissions between korea and japan using international input output analysis abstract this paper is intended to analyze co 2 transmission between japan and south korea through international trade based on 1990 and 1995 international input output data it applied a residual free structural decomposition method proposed by chung and rhee chung h s rhee h c 2001 a residual free decomposition of the sources of carbon dioxide emissions a case of the korean industries energy 26 1 15 30 to emission related international input output analysis for the first time in the decomposition studies this paper is a case study regarding the manner and the extent to which co 2 emissions are influenced by international trade between japan an annex i country and south korea a non annex i country which is of particular interest for the carbon leakage issue in this paper we attempted to show which factors contributed to the changes in emission of the major greenhouse gas in south korea and japan the changes in emission are analyzed in terms of emission intensity input techniques demand composition and trade structures according to our analysis south korea a non annex i country has more energy intensive production structures than japan an annex i country south korea s trade pattern with japan reflects these production features resulting in the korea s comparative advantage in emission intensive products though the degree has somewhat mitigated in 1995 compared to 1990

structural decomposition analysis of sources of decarbonizing economic development in china 1992 2006 abstract to analyze and understand decarbonizing economic development in china this paper undertakes a structural decomposition analysis of the historical change in energy related carbon intensity in china between 1992 and 2006 the results show that the energy related carbon intensity in china decreased by about three fourths between 1992 and 2006 and reduced carbon emissions by about two billion tons the decline in the energy related carbon intensity was mainly caused by changes in production pattern especially changes in energy intensity within each sector between 1992 and 2002 however the most important driving force of carbon intensity from 2002 2006 was not the energy intensity within each sector but the input mix on the other hand changes in demand pattern pushed up the carbon intensity to further decarbonize the economy in the future it is important for china to further enforce policies on shaping the production pattern such as reducing energy intensity and pay more attention to increasing the sustainability of the demand pattern at the same time

differences between continuous and discrete contingent value estimates in a split sample contingent valuation study of willingness to pay wtp for food safety improvements the dichotomous choice dc elicitation method consistently generated much larger estimates of wtp than did a continuous method little or none of these differences was due to bias introduced by the statistical techniques used with the dc data most or all of the difference was due to differences in respondent behavior in addition the continuous wtp responses showed a significant scope effect while the dc responses did not the observed difference in behavior may be attributable in part to yea saying by dc respondents

the institutional economics of biodiversity biological materials and bioprospecting abstract this paper analyzes the fundamental economic and institutional issues connected with biodiversity biological materials and bioprospecting the main findings are that biodiversity and biological materials are common pool goods and must be governed accordingly research and development using biological materials is a dynamic inter temporal asset transformation process that has a mixed economic nature which requires equally diverse and dynamic governance rules and processes in general bioprospecting is best governed by relationship contracting principals that are designed to fit specific economic and institutional conditions however there are no blueprints for access and benefit sharing in addition to extensive consultations with a wide range of stakeholders developing appropriate policy and regulatory solutions requires detailed empirical analyses of specific asset transformation processes in particular technological cultural and institutional settings

giving stated preference respondents time to think results from four countries previous studies have found that contingent valuation cv respondents who are given overnight to reflect on a cv scenario have 30 40 lower average willingness to pay wtp than respondents who are interviewed in a single session this time to think ttt effect could explain much of the gap between real and hypothetical wtp observed in experimental studies yet giving time to think is still rare in binary or multinomial discrete choice studies we review the literature on increasing survey respondents opportunities to reflect on their answers and synthesize results from parallel ttt studies on private vaccine demand in four countries across all four countries we find robust and consistent evidence from both raw data and multivariate models for a ttt effect giving respondents overnight to think reduced the probability that a respondent said he or she would buy the hypothetical vaccines average wtp fell approximately 40 respondents with time to think were also more certain of their answers and a majority said they used the opportunity to consult with their spouse or family we conclude with a discussion of why researchers might be hesitant to adopt the ttt methodology

bias and efficiency of single vs double bound models for contingent valuation studies a monte carlo analysis the dichotomous choice contingent valuation method can be used either in the single or double bound formulation the former is easier to implement while the latter is known to be more efficient we analyse the bias of the ml estimates produced by either model and the gain in efficiency associated to the double bound model in different experimental settings we find that there are no relevant differences in point estimates given by the two models even for small sample size the greater efficiency of the double bound is confirmed although differences tend to reduce by increasing the sample size provided that a reliable pretest is conducted and the sample size is large use of the single rather than the double bound model is warranted

responsibility and trade emission balances an evaluation of approaches this paper compares two concepts to evaluate the international responsibility of a country with respect to its emissions using a multi regional input output model we show that the trade emission balance and the responsibility emission balance yield the same result in practical work however a lack of data availability implies that the same technology assumption has been commonly adopted in that case also a third alternative exists which simply evaluates the emissions embodied in the trade balance of the country this third alternative yields the same results as the other two approaches at the aggregate level at the level of individual products however the results are clearly different and it turns out that the third alternative answers a different question that is it is appropriate for measuring the emission content of the products that cross the border in our empirical application we consider spain in 1995 and 2000 distinguishing nine different gases co 2 ch 4 n 2 o sf 6 hfcs pfcs so 2 nox and nh 3 c 2010 elsevier b v all rights reserved

a test of the equality of closed ended and open ended contingent valuations a test is developed to find whether open ended and closed ended contingent valuation mechanisms lead to significantly different results the test is based on joint estimation of willingness to pay responses to open and closed ended questions asked of the same sample of individuals in a public good example individuals do respond differently depending on question format possible explanations include different incentives for strategic behavior and respondents lack of familiarity with the open ended question type no differences in willingness to pay were found in a private good example

from production based to consumption based national emission inventories abstract under the united national framework convention of climate change unfccc countries are required to submit national emission inventories nei to benchmark reductions in greenhouse gas ghg emissions depending on the definition and system boundary of the nei the mitigation options and priorities may vary the territorial system boundary used by the unfccc has been critiqued for not including international transportation and potentially causing carbon leakage to address these issues past literature has argued in favour of using consumption based nei in climate policy this article discusses several issues in moving from the standard production based nei to consumption based nei first two distinct accounting approaches for constructing consumption based nei are presented the approaches differ in the allocation of intermediate consumption of imported products second a consistent method of weighting production based and consumption based nei is discussed this is an extension of the previous literature on shared responsibility to nei third due to increased uncertainty and a wide system boundary it may be difficult to implement consumption based nei directly into climate policy several alternative options for incorporating consumption based inventories into climate policy are discussed

energy consumption and gdp causality relationship in g 7 countries and emerging markets abstract the causality relationship between energy consumption and income is a well studied topic in energy economics this paper studies the time series properties of energy consumption and gdp and reexamines the causality relationship between the two series in the top 10 emerging markets excluding china due to lack of data and g 7 countries we discover bi directional causality in argentina causality running from gdp to energy consumption in italy and korea and from energy consumption to gdp in turkey france germany and japan hence energy conservation may harm economic growth in the last four countries

designing payments for environmental services in theory and practice an overview of the issues abstract payments for environmental services pes have attracted increasing interest as a mechanism to translate external non market values of the environment into real financial incentives for local actors to provide environmental services es in this introductory paper we set the stage for the rest of this special issue of ecological economics by reviewing the main issues arising in pes design and implementation and discussing these in the light of environmental economics we start with a discussion of pes definition and scope we proceed to review some of the principal dimensions and design characteristics of pes programs and then analyze how pes compares to alternative policy instruments finally we examine in detail two important aspects of pes programs their effectiveness and their distributional implications pes is not a silver bullet that can be used to address any environmental problem but a tool tailored to address a specific set of problems those in which ecosystems are mismanaged because many of their benefits are externalities from the perspective of ecosystem managers pes is based on the beneficiary pays rather than the polluter pays principle and as such is attractive in settings where es providers are poor marginalized landholders or powerful groups of actors an important distinction within pes is between user financed pes in which the buyers are the users of the es and government financed pes in which the buyers are others typically the government acting on behalf of es users in practice pes programs differ in the type and scale of es demand the payment source the type of activity paid for the performance measure used as well as the payment mode and amount the effectiveness and efficiency of pes depends crucially on program design

energy conservation investment do consumers discount the future correctly we argue that the apparently high discount rates attributed to investors making energy conservation investments are not irrational or the result of some market failure rather they may result from an investor recognizing that many conservation investments entail substantial sunk costs in the presence of these costs and uncertainty over future conservation savings consumers should use a higher hurdle rate for investment than if there were no uncertainty simulations suggest that the hurdle rate should be about four times greater than the standard rate an implication of our model is that tax subsidies for the purchase of conservation capital are likely to be ineffective we discuss alternative policy approaches which are more likely to increase energy efficient investment namely mandatory efficiency standards and energy taxes

supply side structural effect on carbon emissions in china abstract this paper carries out a structural decomposition analysis sda of production related carbon emissions in china from 1992 to 2005 by adopting the ghosh input output model it finds that the supply side structure measured by sectoral shares in value added increased production related carbon emissions in 1992 2002 mainly due to the rapid growth of manufacturing sectors but reduced them in 2002 2005 thanks to the decreased shares of carbon intensive sectors whatever the supply side structure forward carbon multipliers of each sector or changes in supply side sectoral shares and related emissions effects calculated by adopting the ghosh input output model were different from their demand side counterparts estimated by adopting the leontief input output model the results suggest optimizing the supply side structure and lowering the forward carbon multipliers to control carbon emissions in the future

interval bidding in a distribution elicitation format interval bidding allows people to report a range of values for a non market good herein we allow people to choose their distribution over this range endogenously we consider a multiplicative error model explaining the willingness to pay wtp which is estimated using a feasible generalized least squares estimator we apply our framework to a representative sample of the french population who were asked about the valuation of a bear conservation programme we find that most participants prefer stating their wtp as a range rather than a point but the shape of the distribution greatly varies across people our results support the use of the interval bidding with endogenous distribution approach in valuation studies

the value of familiarity effects of knowledge and objective signals on willingness to pay for a public good we design and conduct a field experiment in which treated subjects receive a precise and objective signal regarding their knowledge about a public good before estimating their wtp for it we find that the causal effect of objective signals about the accuracy of a subject s knowledge for a public good can dramatically affect their valuation for it treatment caused a significant increase of 85 129 in wtp for well informed individuals we find no such effect for less informed subjects our results imply that wtp estimates for public goods are not only a function of true information states of the respondents but beliefs about those information states

co2 emissions from household consumption in india between 1993 94 and 2006 07 a decomposition analysis abstract co 2 emission from anthropogenic activities is one of the major causes of global warming india being an agriculture dependent country global warming would mean monsoon instability and consequent food scarcity natural disasters and economic concerns however with proper policy interventions co 2 emissions can be controlled input output analysis has been used to estimate direct and indirect co 2 emissions by households for 1993 94 1998 99 2003 04 and 2006 07 complete decomposition analysis of the changes in co 2 emissions between 1993 94 and 2006 07 has been done to identify the causes into pollution energy intensity structure activity and population effects according to broad household consumption categories results indicate that activity structure and population effects are the main causes of increase in co 2 emission from household fuel consumption to identify the causes at the sectoral level a second decomposition has been done for changes between 2003 04 and 2006 07 to identify the causes in the next stage finally alternative energy policy options have been examined for each consumption category to reduce emissions combined strategies of technology upgradation fuel switching and market management in order to reduce co 2 emissions for sectors like batteries other non electrical machinery construction and electronic equipments including television for which all the effects are positive need to be adopted

a structure decomposition analysis of china s production source co2 emission 1992 2002 this paper provides an empirical analysis of the relative impacts of various factors on co2 emissions from production of goods and services in china during two consecutive periods of 1992 1997 and 1997 2002 results show that on the positive side level of final demand for goods and services was the main reason for the increase of production source co2 emission while structure of net export has similar positive effect during the first period of 1992 1997 on the negative side technology factors remains as the main factors reducing emissions the level of net export played some role in the first period but the effects were seen in the second period from energy intensity fuel mix and input mix the results suggest that economic structure be focused as an important factor for co2 emission reduction with construction and transport as two key industries to lower carbon emission

a review of recent multi region input output models used for consumption based emission and resource accounting abstract the interest in consumption based emission and resource accounting has grown significantly many studies juxtapose consumer emissions carbon footprint and producer territorial emissions of greenhouse gases in order to demonstrate the effects of trade on the national emission budget to this end a respectable number of studies have been undertaken worldwide in order to estimate emissions embedded in international trade of numerous countries and world regions input output approaches and increasingly multi region input output mrio models are commonly chosen as they provide an appropriate methodological framework for complete carbon footprint estimates at the national and supra national level with increasing processing capabilities of computers and a wider availability of economic accounts environmental accounts and trade data such models are now being implemented on a wide scale after a brief overview of salient single region input output studies i provide an in depth review of the most recent multi region input output models used for the purpose of consumption based environmental accounting the main methodological features and important results are described for around twenty studies covering the years 2007 to 2009 this is followed by a detailed review of studies dealing with uncertainty in mrio analysis an area which has not received a lot of attention so far i conclude that further research is mainly needed in two areas a improvements in data availability and quality and b improvements in the accuracy of mrio modelling

application of the structural decomposition analysis to assess the indirect energy consumption and air emission changes related to italian households consumption abstract the design of sustainable production and consumption strategies and the assessment of implemented actions require to identify the driving forces that influence the trend of energy consumption and environmental impacts for this purpose the structural decomposition analysis sda was developed as a suitable methodology to analyse the driving forces of the changes in economic energy and environmental indicators the paper presents one of the first italian studies that apply an energy and environmental extended input output model opportunely shaped to the examined context combined with sda in detail it aims at 1 investigating the energy use and the air emissions arisen from the productive sectors to meet the household final demand in the period 1999 2006 2 identifying the sources of variations in energy and environmental indicators and 3 identifying which economic sectors are the most relevant sources of variation and must to be taken into account in the definition of sustainable production and consumption strategies as sources of changes the authors investigate energy and emission intensity effects leontief effect and final demand effect outcomes point out that the increase of the final consumptions often nullifies the energy and environmental benefits due to the improvement of the eco efficiency and to the introduction of innovative technologies of production the sector level analysis shows that tertiary and electricity gas and vapour result the highest italian consuming sectors of energy thus they should be focused for energy saving strategies agriculture hunting and sylviculture and road transports that are primarily sectors affecting air emissions should be taken into account for the reduction of environmental impacts results highlight that the current dichotomy of final demand growth and improvement of eco efficiency represents a key problem that needs to be addressed therefore the presented study can aid to define suitable oriented strategies for the energy and environmental impact reduction

analysis of changes in dutch emission trade balance s between 1996 and 2007 in this paper we construct bilateral emission trade balances etb for the netherlands with 17 regions and compare results for 1996 and 2007 for three different greenhouse gasses we establish a cross sectional analysis of bilateral etbs into a volume of trade composition and technology effect in order to analyze the driving forces of changes over time we perform a structural decomposition analysis of embodied import and export emissions the main findings are that the embodied import emissions have increased by 37 whereas export emissions increased by only 3 which is primarily driven by co2 the 2007 bilateral balances are positive with oecd countries but negative with economies such as russia africa and china the analyses demonstrate that the worsening of the etb is to a large extent caused by the changing composition of trade the dutch economy increasingly exports clean products and imports dirty products

comparing structural decomposition analysis and index to analyze and understand historical changes in economic environmental employment or other socio economic indicators it is useful to assess the driving forces or determinants that underlie these changes two techniques for decomposing indicator changes at the sector level are structural decomposition analysis sda and index decomposition analysis ida for example sda and ida have been used to analyze changes in indicators such as energy use co2 emissions labor demand and value added the changes in these variables are decomposed into determinants such as technological demand and structural effects sda uses information from input output tables while ida uses aggregate data at the sector level the two methods have developed quite independently which has resulted in each method being characterized by specific unique techniques and approaches this paper has three aims first the similarities and differences between the two approaches are summarized second the possibility of transferring specific techniques and indices is explored finally a numerical example is used to illustrate differences between the two approaches

transaction costs and contractual incompleteness the case of electricite de france abstract this paper explores the incompleteness of inter firm contracts through the lens of recent developments in transaction cost economics we built a non truncated contract database representing all the relationships of electricite de france edf with its coal carriers over the period 1977 1997 we tested and corroborated most propositions derived from transaction cost theory relating contractual incompleteness to transaction characteristics even when we considered the complete set of the theory s propositions by endogeneizing the asset specificity at stake in transactions to our knowledge this kind of test has never been conducted before

causal relationship between energy consumption and gdp revisited the case of korea 1970 1999 abstract causal relationship between energy consumption and economic growth is investigated applying a multivariate model of capital labor energy and gdp usual btu energy aggregate is substituted with a divisia aggregate in an attempt to mitigate aggregation bias to test for granger causality in the presence of cointegration among the variables we employ a vector error correction model rather than a vector autoregressive model empirical results for korea over the period 1970 1999 suggest a long run bidirectional causal relationship between energy and gdp and short run unidirectional causality running from energy to gdp the source of causation in the long run is found to be the error correction terms in both directions

determinants of innovation in energy intensive industry and implications for energy policy abstracts the korean government adopted green growth in 2008 as an environmentally friendly growth strategy the energy efficiency of korea however is still relatively low due to the large portion of energy intensive industry eii in its manufacturing sector to improve energy efficiency in korea from an eii perspective a new approach has to be taken because restructuring entire industries would take too much time and be too costly this study aims to emphasize the importance of innovation and analyze the effects of r d on product and process innovations in eii in korea the probit model is adopted to estimate the effects of eight determinants in the korea innovation survey 2008 data the results of this study demonstrate that one of the most important determinants the r d personnel ratio has a strong positive effect on both product and process innovation while another determinant r d intensity only has a strong and positive effect on process innovation in eii because of the resulting innovation energy policies should be enacted to enhance energy efficiency thus the korean government should keep providing incentives for firms in eii to invest more financial and human resources in their r d activities

evolution and drivers of production based carbon emissions in china and india differences and similarities abstract added global carbon emissions have mainly come from china and india since 2012 which indicates importance of two countries in curbing global co2 emissions thus their respective mitigation lessons have more realistic significance in developing more effective mitigation strategy this study compared the dynamic evolution of their co2 emissions and driving factors behind changes in order to find similarities and differences of two countries and provide available policy implications to further reduce carbon emissions firstly both china s and india s carbon emissions have been increasing during 2000 14 3 4 9 9 gt and 0 9 2 0 gt respectively however tendency of two countries varied differently growth of china s co2 have slowed down after the 2008 financial crisis while india s emissions were still accelerating at a high level on account of growing share of carbon intensive energy in the whole energy structure from the national and sectoral perspectives both trends of carbon emissions from two countries have been analyzed according to structural decomposition analysis efficiency gains and slowdown of economic growth in china contributed to most decline of co2 but both production and consumption structures urged emissions up while structure effects in india slightly reduced its co2 but low emission efficiency and expansion of trade scales caused growth of emissions on this basis firstly china should optimize production structures by upgrading industries while india should promote energy transformation and improve energy efficiencies secondly strengthening cooperation and communications with developed countries with advanced technology and experience may make more progress in climate change for two countries experience and lessons of emission reduction deriving from the two would also provide references for other regions

capturing the pharmaceutical value of biodiversity in a developing country the conservation of biodiversity is increasingly being defined as a process made up of three components saving studying and sustainably using biodiversity if the conservation of process is expanded to incorporate the need for both the protection of biodiversity either in situ or ex situ and the generation of valuable information about biodiversity an important issue is the correct balance of investment in these two types of activities this paper explores this issue by focusing on efforts in a developing country to capture the pharmaceutical potential of biodiversity and species information a model of biodiversity investment choice is developed and an analysis of royalty returns to effort in biodiversity protection taxonomic information and the collection of biotic samples is conducted based on data from costa rica the results suggest that although a country can be adequately compensated for its investment in the generation of taxonomic information it is unlikely that pharmaceutical prospecting alone will cover the high opportunity costs of biodiversity protection

china s energy consumption under the global economic crisis decomposition and sectoral analysis abstract it is now widely recognized that there is a strong relationship between energy consumption and economic growth most countries energy demands declined during the economic depression of 2008 2009 when a worldwide economic crisis occurred as an export oriented economy china suffered a serious exports decline in the course of the crisis however it was found that energy consumption continued to increase against such a background this paper aims to assess and explain the factors causing the growth of energy consumption in china first we will explain the impact of domestic final use and international trade on energy consumption by using decomposition analysis second embodied energy and its variation across sectors are quantified to identify the key sectors contributing to the growth lastly the policy implications for long term energy conservation are discussed the results show that the decline in exports was one of the driving forces for energy consumption reduction in the crisis but that the growth of domestic demand in manufacturing and construction largely stimulated by economic stimulus plans had the opposite effect on energy consumption international trade contributed to decreasing energy consumption of china during and after the crisis because the structure of exports and imports changed in this period

valuing biodiversity for use in pharmaceutical research biodiversity prospecting has been touted as a mechanism for both discovering new pharmaceutical products and saving endangered ecosystems it is unclear what values may arise from such activities however evidence from transactions is incomplete and existing theoretical models are flawed we calculate an upper bound on the value of the marginal species even under favorable assumptions this bound is modest slightly modified assumptions lead to drastically lower estimates we extend our findings to the value of the marginal hectare of habitat and find that the incentives for habitat conservation generated by private pharmaceutical research are also at best very modest

from bioprospecting to reflexive governance in this paper i evaluate the contribution of new institutional economics to reflexive governance in the field of bioprospecting my hypothesis is that the design of governance arrangements that are both efficient and legitimate necessitates taking into account the reflexivity of the actors on the proposed institutional design in considering this hypothesis i apply current theoretical insights from new institutional economics as developed by oliver williamson and douglas north to the issue of complex contractual relationships in the field of bioprospecting building on these insights i propose some means for ameliorating the current proposals for institutional framing of the contractual relationships d 2005 elsevier b v all rights reserved

input output analysis of co2 emissions embodied in trade the effects of sector aggregation abstract energy related co2 emissions embodied in international trade have been widely studied by researchers using the environmental input output analysis framework it is well known that both sector aggregation and spatial aggregation affect the results obtained in such studies with regard to the latter past studies are often conducted at the national level irrespective of country or economy size for a large economy with the needed data studies may be conducted at different levels of spatial aggregation we examine this problem analytically by extending the work of su et al su b huang h c ang b w zhou p 2010 input output analysis of co2 emissions embodied in trade the effects of sector aggregation energy economics 32 1 166 175 on sector aggregation we present a numerical example using the data of china and by dividing the country into eight regions it is found that the results are highly dependent on spatial aggregation our study shows that for a large country like china it is meaningful to look into the effect of spatial aggregation

extended divisia index decomposition of changes in energy intensity a case of korean manufacturing industry abstract this study aims to examine the energy efficiency of the manufacturing industry of korea by using the extended divisia index decomposition of choi and ang 2012 first we applied the sato vartia index decomposition to the energy intensity of the manufacturing industry in korea second we attributed the growth rate of aggregate energy intensity to 10 sub manufacturing industries through two channels real energy intensity and structural change the result of the decomposition illustrates that the aggregate energy intensity index decreased in the period 1981 2010 the index decomposition analysis demonstrates that real energy intensity decreased by 85 85 whereas structural change increased energy intensity by 69 37 over the same period of time the negative effect of structural change is partly a result of the increasing portion of energy intensive industry in manufacturing the result reflects that industrial structure in korea can be an important aspect for improving energy efficiency

can payments for environmental services help reduce poverty an exploration of the issues and the evidence to date from latin america summary this paper examines the main ways in which payments for environmental services pes might affect poverty pes may reduce poverty mainly by making payments to poor natural resource managers in upper watersheds the extent of the impact depends on how many pes participants are in fact poor on the poors ability to participate and on the amounts paid although pes programs are not designed for poverty reduction there can be important synergies when program design is well thought out and local conditions are favorable possible adverse effects can occur where property rights are insecure or if pes programs encourage less labor intensive practices 2004 elsevier ltd all rights reserved

protest response and willingness to pay for culturally significant urban trees implications for contingent valuation method the contingent valuation method cvm could assist green space planning management and appreciation by assigning a monetary value to urban trees however the use of cvm is limited by its inherent methodological weaknesses a critical concern is the existence of a large proportion of survey respondents providing zero willingness to pay wtp and that these responses are not amenable to economic theory known as protest responses censoring protest responses from further treatment is a common practice which warrants reconsideration in light of our cvm survey results the survey involved 800 residents requested to state their wtp for preserving the culturally significant stonewall trees in urban hong kong about 28 of respondents returned a zero wtp for all respondents the strength of protest beliefs was assessed and the relationship between protest beliefs and wtp were examined our analysis produced contradictory results some protest items varied negatively with wtp as expected but other items increased with it respondents stated positive wtp harbored latent protest beliefs which are related to non economic preference the findings stand at odds with the assumptions underlying the censoring treatment and raise questions about the validity of wtp estimates these methodological implications should be taken into account in using cvm

calculation and decomposition of indirect carbon emissions from residential consumption in china based on the input output model abstract based on the input output model and the comparable price input output tables the current paper investigates the indirect carbon emissions from residential consumption in china in 1992 2005 and examines the impacts on the emissions using the structural decomposition method the results demonstrate that the rise of the residential consumption level played a dominant role in the growth of residential indirect emissions the persistent decline of the carbon emission intensity of industrial sectors presented a significant negative effect on the emissions the change in the intermediate demand of industrial sectors resulted in an overall positive effect except in the initial years the increase in population prompted the indirect emissions to a certain extent however population size is no longer the main reason for the growth of the emissions the change in the consumption structure showed a weak positive effect demonstrating the importance for china to control and slow down the increase in the emissions while in the process of optimizing the residential consumption structure the results imply that the means for restructuring the economy and improving efficiency rather than for lowering the consumption scale should be adopted by china to achieve the targets of energy conservation and emission reduction

total embodied energy requirements and its decomposition in china s agricultural sector abstract humanity faces the important challenge of understanding and integrating human and natural processes including agriculture in china the scarcity of arable land 0 09 ha per capita increasing population and migration of the workforce to cities pose a significant challenge for food security agricultural energy productivity has therefore become a key concern in this study we used input output analysis to measure energy productivity at a national agro ecosystem scale for china using the total embodied energy requirement teer to reveal hidden energy flows we introduced a structural decomposition technique that reveals how changes in teer for the agricultural sector were driven by changes in energy use technology and the inter relationships among two agricultural sectors farming and animal husbandry the results will help both policymakers and farmers to improve the efficiency and environmental compatibility of agricultural production declining teer for both sectors means that china s overall agro ecosystem has increased its energy productivity since 1978 due to improved relationships between the agricultural sectors and increased use of biological energy however the net positive energy income decreased in the farming sector and an increasing proportion of fossil energy use accompanied by increased energy income in the animal sector provide incentives to increase yield and decrease labor by using more fossil energy thus raising more animals in the animal husbandry sector overuse of fossil energy since 1990 has resulted in decreasing fossil energy efficiency requiring immediate measures to improve the use of fossil fuel intensive materials such as fertilizers

embodied energy use in china s industrial sectors abstract as the world s top energy consumer china is facing a great challenge to solve its energy supply issue in this paper energy use from all industrial sectors in china s economy of 2007 was explored by conducting an extended environmental input output analysis we compare the energy consumption embodied in the final demand for goods and services from 29 sectors with the energy demand required for the actual production process in each sector two different viewpoints for sectoral energy use have been presented energy use is directly allocated to the producer entity and energy use is reallocated to sector s supply chain from consumption perspective our results show that considerable amount of energy use is embodied in the supply chain especially for construction and other service activities sectors which is not detected if energy use is allocated on a production basis when further dividing embodied energy consumption into direct energy consumption and indirect energy consumption total indirect energy consumption is much higher than that of total direct energy consumption accounting for 80 6 of total embodied energy consumption in 2007 our results provide a more holistic picture on sectoral energy consumption and therefore can help decision makers make more appropriate policies

discrete choice under preference uncertainty an improved structural model for contingent valuation abstract this paper is concerned with discrete choice contingent value estimation in the presence of response errors we attempt to extend the theoretical frameworks developed by hanemann 1984 amer j agric econom 66 332 341 and cameron 1988 j environ econom management 15 355 379 by introducing preference uncertainty with individual respondents we assume that respondents have incomplete knowledge about their true valuation of a nonmarket resource and thus may give wrong yes no answers on whether or not to pay a given bid amount for the resource a post decisional confidence measure for each observed yes no answer is elicited for characterizing the degree of preference uncertainty with the help of this confidence measure we develop an improved structural model for deriving value estimates data from a forest environment valuation survey are used for the empirical estimations

a review on energy systems and ghg emissions reduction plan and policy of the republic of korea past present and future abstract the primary objectives of this study were to understand the energy plans and policies of the republic of korea rok and outline its development in the energy sector both qualitative and quantitative information were gathered and evaluated in the context of the defined objectives the study has outlined that the primary motivational factor for achieving the current improved energy status of the rok was to support the rapid industrial growth and socio economic development of the country the major steps taken were to manage the country s escalating energy demand and to minimize the greenhouse emissions in energy sector along its progressive economic development the economic growth of the country had good correlation with the escalating fossil fuel consumption this is however among the great concerns in the country in today s global agenda of sustainable energy managements the country has been primarily relying on the imported energy sources which averaged to 84 including nuclear generation of the total primary energy supply tpes during the period of 2000 2014 oil has been the main source of energy supply in the country followed by coal and natural gas penetration of renewable energy technologies was primarily motivated to meet the country s strategic goals including the downscaling of ghg emission by 37 by 2030 compared to the business as usual bau situation despite the different initiations in the energy management renewable energy sources covered only 4 5 of the tpes in 2014 in addition the country s urgent need now is also towards the management of the available natural resources to support the growing demand of bio economy at this particular interest the country needs to identify the sustainable availability of resources to balance the multi fold sectors this demands comprehensive energy system analysis along with identifying the avenues of the utilization of biomass resources

an analysis of co2 emissions of japanese industries during the period between 1985 and 1995 this paper examines the factors that have an effect on co2 emissions produced by japanese industries between 1985 and 1995 by using input output tables the effects of environmental technological changes etc and production technological changes ptc on co2 emissions are considered separately furthermore backward and forward linkage effects in each sector that shows the extent to which each sector spreads or receives co2 emissions impacts across all of sectors will be calculated the results show that both types of technologies contributed to a decrease in co2 emissions during the bubble economy of the late 1980s but not during the recession of the early 1990s trade factors succeeded in decreasing co2 emissions in both periods thus trade structures facilitated the turning of japan into a net importer of co2 emissions between 1985 and 1995 the backward and forward linkage effects also decreased during the boom of the late in 1980s but not the recession of the early 1990s while the chemical products and electrical machinery sectors continued to reduce both effects this indicates that both sectors were relatively successful in decreasing their co2 emissions impacts between 1985 and 1995

revisiting drivers of energy intensity in china during 1997 2007 a structural decomposition analysis the decline of china s energy intensity slowed since 2000 during 2002 2005 it actually increased reversing the long term trend therefore it is important to identify drivers of the fluctuation of energy intensity we use input output structural decomposition analysis to investigate the contributions of changes in energy mix sectoral energy efficiency production structure final demand structure and final demand category composition to china s energy intensity fluctuation during 1997 2007 we include household energy consumption in the study by closing the input output model with respect to households results show that sectoral energy efficiency improvements contribute the most to the energy intensity decline during 1997 2007 the increase in china s energy intensity during 2002 2007 is instead explained by changes in final demand composition and production structure changes in final demand composition are mainly due to increasing share of exports while changes in production structure mainly arise from the shift of chinese economy to more energy intensive industries changes in energy mix and final demand structure contribute little to china s energy intensity fluctuation from the consumption perspective growing exports of energy intensive products and increasing infrastructure demands explain the majority of energy intensity increase during 2002 2007

biodiversity in the marketplace what is the nature of biodiversity as an economic commodity and why does it matter how would its conservation contribute economically to our well being in this article geoffrey heal considers three issues why is biodiversity important from an economic perspective what kind of commodity is it does our usual economic mechanism the market system have the capacity to appreciate the economic value of biodiversity the author first tries to characterize biodiversity from an economic perspective and then considers the capacity of our main economic institutions to realize the value of biodiversity and ensure that it is treated in a way commensurate with its importance

driving forces of rapid co2 emissions growth a case of korea abstract this study aims to investigate korea s final demand structure and its impacts on co 2 emissions in order to reduce co 2 emissions and develop environmental policy directions based on the environmentally extended input output model this study adopts a two step approach 1 to estimate the embodied emissions and their intensities for 393 sectors induced by final demand and 2 to calculate the driving factors of emission growth between 2003 and 2011 and then evaluate the result by using structural decomposition analysis sda the findings of this study demonstrate that the impact of composition change in export with less embodied emission intensities tends to offset the increase in co 2 emission by the export scale growth the relatively low residential electricity price has resulted in the rapid growth of household electricity consumption and significantly contributed to emissions growth the result of sda indicates that korea s final demand behavior yielded high carbonization over the same period the findings suggest that korean government should promote exports in industries with less embedded co 2 in order to protect environments in addition emission information of each product and service should be provided for consumers to change their purchase patterns towards contributing to low carbon emissions as active players

industrial co2 emissions from energy use in korea a structural decomposition analysis abstract this paper attempts to quantify energy consumption and co 2 emissions in the industrial sectors of korea the sources of the changes in co 2 emissions for the years 1990 2003 are investigated in terms of a total of eight factors through input output structural decomposition analysis changes in emission coefficient caused by shifts in energy intensity and carbon intensity changes in economic growth and structural changes in terms of shifts in domestic final demand exports imports of final and intermediate goods and production technology the results show that the rate of growth of industrial co 2 emissions has drastically decreased since the 1998 financial crisis in korea the effect on emission reductions due to changes in energy intensity and domestic final demand surged in the second period 1995 2000 while the impact of exports steeply rose in the third period 2000 2003 of all the individual factors economic growth accounted for the largest increase in co 2 emissions the results of this analysis can be used to infer the potential for emission reduction in korea

the importance of energy quality in energy intensive manufacturing evidence from panel cointegration and panel fmols this paper expands on the panel gdp energy cointegration modeling literature it does so by using data disaggregated along sectoral lines and adjusting energy consumption for the quality of the energy source e g electricity is of higher quality than oil which is of higher quality than coal in order to examine the role of energy quality in the five most energy intensive manufacturing sectors iron and steel non ferrous metals non metallic minerals chemicals and pulp and paper the database was constructed by combing energy consumption and energy price data to construct the energy quality index from the iea with economic data value added labor employed and physical capital from the oecd s structural analysis database in addition to finding the variables analyzed are panel i 1 and cointegrated for each sector based panel the long run elasticity estimates from panel fmols indicate the importance of energy quality primarily the shift toward the use of high quality electricity in these energy intensive manufacturing sectors in each case the elasticity for energy quality is greater than that for conventionally measured energy consumption sometimes orders of magnitude greater indeed the elasticity of conventionally measured energy consumption is insignificant to very small for three of the five sectors also when using the energy quality measure the importance of energy consumption relative to the other production factors stands out such results are useful for both energy gdp cointegration causality modelers and cge modelers who may need to estimate elasticities

respondent uncertainty and ordering effect on willingness to pay for salt marsh conservation in the brest roadstead france abstract this paper explores the potential link between the sensitivity of willingness to pay wtp to the order of presenting bid amounts in contingent valuation questions ordering effect and respondent uncertainty the resource being valued is a public project to protect salt marshes against the spread of an invasive aquatic plant in the brest roadstead france valuation uncertainty is captured through a variant of payment card format where respondents are given the opportunity to report their wtp as either a single value option a or an interval of values option b the ordering effect is tested using both parametric models that ignore and control for the potential sample selection bias related to the choice between option a and option b as well as non parametric models the results suggest that 1 respondents place substantial wtp values on salt marsh conservation and 2 the ordering effect is linked to respondent uncertainty since only uncertain respondents react differently to changes in the order of presenting bid amounts specifically for uncertain respondents putting bid amounts in ascending order yields lower welfare estimates than putting bid amounts in descending order or random order policy recommendations and options to deal with ordering effect are discussed

valuing public goods discrete versus continuous contingent valuation responses independent applications of open ended and dichotomous choice formats are compared using tests of means estimating joint likelihood functions and nonparametric tests of distributions the null hypothesis of no difference in the open ended and dichotomous choice estimates of central tendency cannot be rejected for two out of three data sets while estimated standard deviations are significantly different for all three data sets in addition actual dichotomous choice means and standard deviations exceed those from comparable synthetic dichotomous choice data sets suggesting either open ended questions underestimate values or dichotomous choice bid structures may lead to systematic overestimates

what causes the change in energy demand in the economy the role of technological change this paper proposes a simple and theoretically clear approach to the estimation of technological change in a multisector general equilibrium framework this study employs the multiple calibration decomposition analysis mcda to evaluate technological change that is responsible for changes in energy use and carbon dioxide emissions in the japanese economy in the oil crises period from 1970 to 1985 the mcda serves as an elementary way of separating structural change due to technological change from that due to price substitution effects capturing the interdependence among economic sectors the empirical result provides a better understanding of the effects on the economy of technological change in that significant period

comparing continuous and discrete contingent valuation questions this paper explores two commonly used methods to elicit an individual s willingness to pay wtp for a public good in contingent valuation studies currently the most preferred method is the take it or leave valuation question or discrete valuation question dvq where the respondent accepts or rejects a suggested cost for the good the traditional method the continuous valuation question cvq simply asks an individual to state his wtp for the suggested change in the provision of a public good like cleaner air we introduce a simple way to compare the results from these two methods we also test the anchoring behavior suggested in the psychological literature on choice under uncertainty the results do not support the anchoring hypothesis but suggest the hypothesis that people perceive the two tested valuation questions differently

carbon dioxide emission drivers for a typical metropolis using input output structural decomposition analysis as the capital of china beijing is regarded as a major metropolis in the world study of the variation in temporal co2 emissions generated by the driving forces in beijing can provide guidance for policy decisions on co2 emissions mitigation in global metropolises based on input output structural decomposition analysis io sda we analysed the driving forces for the increment in co2 emissions in beijing from both production and final demand perspectives during 1997 2010 according to our results the co2 emission growth in beijing is driven mainly by production structure change and population growth partly offset by co2 emission intensity reduction as well as the decline in per capita final demand volume during the study period final demand structure change has a limited effect on the change in the co2 emissions in beijing from the final demand perspective urban trades urban residential consumption government consumption and fixed capital formation are mainly responsible for the booming emissions this study showed how the top down io sda methodology was implemented on a city scale policy implications from this study would be helpful for addressing co2 emissions mitigation in global capital cities and metropolises

a multi region multi sector decomposition and attribution analysis of aggregate carbon intensity in china from 2000 to 2015 abstract index decomposition analysis ida has been used to analyze driving forces of aggregate carbon intensity aci however previous studies mostly explained changes in aci from either sectoral or regional perspective but rarely looked into driving forces of aci from both sectoral and regional perspectives under a unified and consistent framework to fill the research gap this study proposed a multi region multi sector decomposition and attribution approach to analyze driving forces of aci from both sectoral and regional perspectives the empirical results in china show that the aci declined by 33 from 2000 to 2015 from the sectoral perspective the decline can be mainly attributed to the significant energy efficiency improvement in six high energy intensive industries however the rapid growth in electricity consumption especially in chemicals and iron and steel and the expansion of iron and steel industry during 2000 2005 greatly offset the negative effect from energy efficiency from the regional perspective the aci decline can be primarily due to an extensive improvement in energy efficiency in most regions on the contrary the increasing dependency on coal particularly in shandong inner mongolia and guangdong and the increased share of carbon intensive industries in some provinces such as guangxi and sichuan markedly increased aci based on the results the effectiveness of underlying sectoral and regional level policies and measures implemented for aci reduction in china were evaluated
