household preferences of hybrid home heating systems a choice experiment application abstract the residential heating sector presents considerable energy savings potential as numerous heating solutions for reducing electricity consumption and utilizing renewable energy sources are available in the market the aim of this paper is to examine determinants of household heating system choices and to use this information for policy planning purposes this paper investigates residential homeowner attitudes regarding innovative hybrid home heating systems hhhs with choice experiment heating system scenarios are designed to represent the most relevant primary and supplementary heating alternatives currently available in finland the choice sets include six main heating alternatives district heat solid wood wood pellet electric storage heating ground heat pump and exhaust air heat pump that are described by five attributes supplementary heating systems investment costs operating costs comfort of use and environmental friendliness the results imply that hhhss generally appear to be accepted among households however several factors affect perceptions of these technologies the results reveal differing household attitudes toward the main heating alternatives and show that such views are affected by socio demographic characteristics age living environment education etc the results suggest that households view supplementary heating systems especially solar based favorably the other attributes studied also play a significant role in decision making

why does the combination of the european union emissions trading scheme and a renewable energy target makes economic sense abstract the european climate and energy mix of targets and policies has been criticised by many economists in particular it is often argued that the renewable energy targets do not make economic sense because they represent an expensive option to reduce co2 emissions within a cap and trade scheme such as the european union emissions trading scheme eu ets in addition it has also been claimed that support for renewable electricity deployment negatively interacts with the eu ets having a dampening effect on the co2 price which favours the dirtiest technologies and is detrimental for the greener ones in this article we argue that this mainstream economic view is short sighted and that a multidisciplinary economic analysis of the climate and energy policy mix is required mainstream economic analysis is based on a narrow approach for the assessment of instrument combinations and neglects relevant insights from several economic disciplines including innovation economics and political economy approaches in reality economic theory supports the combination of an ets and renewable energy targets the existence of different policy goals and market failures the demand pull influence of renewable energy policies on innovation a political economy approach and the different risk exposure of renewable energy technologies call for a policy mix although policy combinations are not a panacea and bring problems on their own the aforementioned negative interaction between renewable energy deployment and the carbon price in the eu ets can be mitigated through appropriate coordination and or instrument choice and design

energy demand substitution from biomass to imported kerosene evidence from tanzania abstract we analyze domestic household energy demand and use patterns in tanzania using a detailed household survey of purchase transactions a multivariate probit model and the quaids modeling framework the main fuel sources that we study are kerosene charcoal and firewood these three accounted for 96 5 of spending on energy by households charcoal and firewood are used for cooking while kerosene is used for lighting and cooking kerosene is almost exclusively imported while charcoal and firewood are produced domestically these fuel sources are important given the impacts of wood harvesting on the environment and kerosene imports on public finances we find a statistically significant response in kerosene demand to charcoal prices suggesting a pattern of substitution but no strong substitution relationships between other fuel pairs these results which we use in a simulation of tariff change imply that policies centered on price changes may not be effective in changing consumer behavior unless alternative sources of energy are readily accessible

the structure of energy efficiency investment in the uk households and its average monetary and environmental savings abstract socioeconomic and behavioural variables that influence the household s adoption of energy efficiency measures such as cavity and loft insulation and upgrades to the boiler are identified contrary to previous literature by extending brechling and smith s 1994 and hassett and metcalf s 1995 models it is shown that the application of the energy act 2011 which contains provisions on the green deal the new energy company obligation eco and the private rented sector needs to follow a tailored strategy to reach the low adoption households identified by my model moreover for the current adopters of the analysed measures average monetary and environmental adoption benefits are estimated based on parti and parti s 1980 demand model these estimates are smaller than their expected values showing an important energy efficiency gap in the sector particularly low cost measures can bring important savings that can help to meet the pay as you save rule i e the golden rule of the new regulation my model also shows that a poor state of dwelling repair can reduce the adoption benefits increasing the need of subsidies that will be financed through consumer s energy bills however this can increase the number of households in fuel poverty

haggling over substitutes abstract using a model of substitutable goods i determine generic conditions on tastes which guarantee that fixed prices are not optimal the fully optimal tariff includes lotteries that is a profit maximising seller would employ a haggling strategy we show that the fully optimal selling strategy in a class of cases requires a seller to not allow themselves to focus on one good but to remain haggling over more than one good this throws new light on the selling strategies used in diverse industries these insights are used to provide a counter example to the no lotteries result of mcafee and mcmillan j econ theory 46 1988 335

supply of renewable energy sources and the cost of eu climate policy abstract what are the excess costs of a separate 20 target for renewable energy as a part of the eu climate policy for 2020 we answer this question using a computable general equilibrium model worldscan which has been extended with a bottom up module of the electricity sector the model set up makes it possible to base the calibration directly on available estimates of costs and capacity potentials for renewable energy sources in our base case simulation the costs of eu climate policy with the renewables target are 6 higher than those of a policy without this target the uncertainty in this estimate is considerable however and depends on our assumptions about the availability of low cost renewable energy the initial cost level the steepness of the supply curves and share of renewable energy in the baseline within the range we explore the excess costs vary from zero when the target is not a binding constraint to 32 when the cost progression and the initial cost disadvantage for renewable energy are high and its initial share is low

good things do not always come in threes on the excess cost of overlapping regulation in eu climate policy since the mid 1990 s the european union eu aims at pushing global climate policy the objective is to promote international cooperation by the adoption of substantial eu wide greenhouse gas emission reduction targets and their least cost implementation our quantitative impact assessment of the eu climate and energy package shows that the myriad of instruments used in the eu to curb greenhouse gas emissions is doomed to generate substantial excess cost we conclude that eu climate and energy policy should better disentangle its choices of objectives targets and policy instruments on rigorous economic grounds in order to improve the coherence and overall cost effectiveness of policy initiatives

the european renewable energy target for 2030 an impact assessment of the electricity sector abstract the european union set binding targets for the reduction of greenhouse gases ghg and the share of renewable energy re in final energy consumption by 2020 the european council agreed to continue with this strategy through to 2030 by setting a re target of 27 in addition to a ghg reduction target of 40 we provide a detailed sectoral impact assessment by analyzing the implications for the electricity sector in terms of economic costs and the regional distribution of investments and shares of electricity generated from renewable energy sources res e according to the impact analysis by the european commission the 27 re target corresponds to a res e share of 49 our model based sensitivity analysis on underlying technological and institutional assumptions shows that the cost effective res e share varies between 43 and 56 secondly we quantify the economic costs of these variants and those which would be incurred with higher shares the long term additional costs for higher res e shares would be less than 1 of total system costs the third aspect relates to the regional distribution of eu wide efforts for upscaling renewables we point out that delivering high res e shares in a cost effective manner involves considerably different efforts by the member states

homeowner satisfaction with low carbon heating technologies abstract positive word of mouth communication resulting from the experiences of early adopters is a crucial factor in the uptake and diffusion of low carbon energy technologies over time hence the goal of this research is to study homeowner satisfaction with respect to residential heating systems rhs based on renewable energies in particular this paper focuses on the role of attributes of the home homeowners socio demographic characteristics rhs related knowledge and adoption motivations for this purpose we apply a linear regression model on a dataset obtained from a survey among homeowners in germany n 2135 that had adopted an rhs shortly before the survey was conducted moreover we investigate differences between groups of homeowners by means of t tests and anova our research shows that the fulfilment of the motivations for adopting an rhs are relevant factors explaining satisfaction with newly adopted rhs in particular the preference to have an rhs that is compatible with daily habits and routines has a strong impact on satisfaction furthermore we find the degree of rhs related knowledge relevant as well socio demographic aspects such as age university degree gender or income are found to be less important we also find differences between groups of adopters specifically adopters of a gas fired condensing boiler with solar thermal support or a heat pump are less satisfied than adopters of a wood pellet fired boiler we conclude that information and education campaigns on clean energy technologies such as rhs based on renewable energies may have a positive impact on homeowner satisfaction resulting in a positive word of mouth recommendation and influenec of others

foundations of dominant strategy mechanisms wilson 1987 criticizes applied game theory s reliance on common knowledge as sumptions in reaction to wilson s critique the recent literature of mechanism design has adopted the goal of finding detail free mechanisms in order to eliminate this re liance in practice this has meant restricting attention to simple mechanisms such as dominant strategy mechanisms however there has been little theoretical foundation for this approach in particular it is not clear the search for an optimal mechanism that does not rely on common knowledge assumption would lead to simpler mechanisms rather than more complicated ones this paper tries to fill the void in the context of an expected revenue maximizing auctioneer we investigate some foundations for using simple dominant strategy auctions

explaining the attacker s advantage technological paradigms organizational dynamics and the value network abstract understanding when entrants might have an advantage over an industry s incumbent firms in developing and adopting new technologies is a question which several scholars have explained in terms of technological capabilities or organizational dynamics this paper proposes that the value network the context within which a firm competes and solves customers problems is an important factor affecting whether incumbent or entrant firms will most successfully innovate in a study of technology development in the disk drive industry the authors found that incumbents led the industry in developing and adopting new technologies of every sort identified by earlier scholars at component and architectural levels competency enhancing and competency destroying incremental and radical as long as the technology addressed customers needs within the value network in which the incumbents competed entrants led in developing and adopting technologies which addressed user needs in different emerging value networks it is in these innovations which disrupted established trajectories of technological progress in established markets that attackers proved to have an advantage the rate of improvement in product performance which technologists provide may exceed the rate of improvement demanded in established markets this mismatch between trajectories enables firms entering emerging value networks subsequently to attack the industry s established markets as well

green transition of energy systems in rural china national survey evidence of households discrete choices on water heaters abstract energy systems in rural china are experiencing a transition from traditional fossil fuels to renewables this paper aims to investigate the potential factors that influence the choices of rural residents regarding water heaters with a focus on the low carbon transition to solar water heating systems to this end a face to face questionnaire survey is undertaken with 3404 rural households randomly selected among 12 representative provinces a comprehensive set of discrete choice modelling approaches were used the empirical results show that 1 sociodemographic variables have significant effects on residents first stage choice of a water heater to buy or not to buy but few effects on the second stage decision to choose electric lpg or solar water heaters which type to buy 2 information spillover is important to facilitate the usage of water heaters particularly of solar products 3 the electricity price which is regulated at a very low rate has no apparent effect on the choice of solar water heaters 4 government subsidy has a significant effect in the first stage but no differentiated effect on the decision choice in the second stage policy and managerial implications are presented to speed up the ongoing low carbon transition of energy systems in china

scenario analysis on co2 emissions reduction potential in china s electricity sector abstract with the approach of the year 2012 a new round of international negotiations has energized the entire climate change community with this analyses on sector based emissions reduction and mitigation options will provide the necessary information to form the debate in order to assess the co2 emissions reduction potential of china s electricity sector this research employs three scenarios based on the long range energy alternative planning system leap model to simulate the different development paths in this sector the baseline scenario the current policy scenario and the new policy scenario seek to gradually increase the extent of industrial restructuring and technical advancement results imply that energy consumption and co2 emission in china s electricity sector will rise rapidly in all scenarios until 2030 triple or quadruple the 2000 level however through structural adjustment in china s electricity sector and through implementing technical mitigation measures various degrees of abatement can be achieved these reductions range from 85 to 350 million tons co2 per year figures that correspond to different degrees of cost and investment demand side management and circulating fluidized bed combustion cfbc ranked in order are employed prior to use to realize emissions reduction followed by supercritical plants and the renovation of conventional thermal power plants in the long term nuclear and hydropower will play the dominant role in contributing to emissions reduction it is also suggested that a self restraint reduction commitment should be employed to help contribute to the reduction of emission intensity an avenue that is more practical for china in light of its current development phase setting the year 2000 as the base year the intensity reduction target could possibly range from 4 2 to 19 4 dependent on the implementation effectiveness of various mitigation options

modelling household energy expenditures using micro data this paper is concerned with the empirical modeling of domestic demand for energy in the united kingdom at the level of the individual household a two stage budgeting model of household demand for energy conditional on durable ownership is developed at the first stage income is allocated between energy and nonenergy consumption while at the second stage energy expenditure is disaggregated the second stage allocation is assumed to be between gas electricity and a composite good other fuels estimation takes place using a sample of some 50 000 households drawn from the annual u k family expenditure survey for the years 1972 83 a source that has not been fully exploited in the analysis of energy demand to date copyright 1989 by royal economic society

heating technology and energy use a discrete continuous choice approach to norwegian household energy demand abstract the aim of this paper is to describe the structure of the household s energy demand as a discrete continuous choice and on this basis establish an econometric model suitable for the data available in the norwegian energy surveys the discrete appliance choice is specified as a multinomial logit model with a mixture of appliance attributes operating costs and individual characteristics income housing unit characteristics etc as explanatory variables in the next step the continuous choice of energy use is modelled conditional on the appliance choice the energy prices turn out to be significant both when estimating the appliance choice and the conditional energy demand the estimated price elasticity for energy exceeds minus unity the paper discusses how this relatively strong price response should be interpreted in the context of other econometric analysis with no explicit appliance dependence finally the significance of the many household characteristics at both stages of the model signals a high degree of heterogeneity within the households which justifies the use of detailed micro data in the modelling of the energy demand

bundling as an optimal selling mechanism for a multiple good monopolist abstract multiple objects may be sold by posting a schedule consisting of one price for each possible bundle and permitting the buyer to select the price bundle pair of his choice we identify conditions that must be satisfied by any price schedule that maximizes revenue within the class of all such schedules we then provide conditions under which a price schedule maximizes expected revenue within the class of all incentive compatible and individually rational mechanisms in the n object case we use these results to characterize environments mainly distributions of valuations where bundling is the optimal mechanism in the two and three good cases

a conjoint analysis of corporate preferences for the sectoral crediting mechanism a case study of shanxi province in china it is crucial to understand corporate preferences in designing and planning new market based instruments using the method of conjoint analysis this paper evaluates corporate preferences for policy alternatives of the sectoral crediting mechanism aiming at supporting its discussions and development data were collected from 94 companies in all 11 prefecture level cities of shanxi province china the results confirm that companies are most concerned about three policy attributes domestic policy instruments the relationship with the clean developing mechanism and the principle of common but differentiated responsibilities from the viewpoint of the chinese businesses surveyed the ideal policy alternative has a domestic policy instrument in which installations with voluntary targets receive tradable units while co existing with the clean developing mechanism and providing opportunities to get financial and technical assistance from developed countries meanwhile the coverage of the sectoral crediting mechanism could be expanded to small companies that are the most inefficient and thus have the lowest abatement costs in some sectors the results of this study are important in light of ongoing discussions and developments of the sectoral crediting mechanism in china

household biomass energy choice and its policy implications on improving rural livelihoods in sichuan china abstract it is widely known that a switch from traditional biomass energy to modern clean safe and efficient energy could improve local rural livelihoods by enhancing the access to high quality energy and reducing the negative impacts of traditional biomass energy on health environment and living standards hence in this paper we used alternative specific conditional logit model asclm to examine the rural household energy choice behaviors in sichuan province of china from the perspective of revealed and stated preferences the results show that the fuel switching in our study region is not a simple unidirectional process from traditional biomass energy to modern fuels as incomes improve household energy choice behaviors could be not only affected by energy specific characteristics such as fuel price smoky level and safety risk but also influenced by household specific factors such as income level age and educational level of the decision maker household demographic structure number of people frequently eating at home distance to the nearest biomass collecting spot and household location suggesting that government should attach more importance to simultaneously improve energy quality control energy price and enhance household socio economic status

price sensitivity of residential energy consumption in norway abstract the main aim of this paper is to test the stability of the results of a model which focus on the relationship between the choice of heating equipment and the residential energy consumption the results for the income and energy price variables are of special interest stability in the time dimension is tested by applying the model on micro data for each of the years 1993 1995 the parameter estimates are stable within a 95 confidence interval however the estimated impact of the energy price variable on energy consumption was considerably weaker in 1994 than in 1993 and 1995 the results for two different income groups in the pooled data set are also subject to stability testing the energy price sensitivity in residential energy consumption is found to be higher for high income households than for low income households

motivational factors influencing the homeowners decisions between residential heating systems an empirical analysis for germany heating demand accounts for a large fraction of the overall energy demand of private households in germany a better understanding of the adoption and diffusion of energy efficient and renewables based residential heating systems rhs is of high policy relevance particularly against the background of climate change security of energy supply and increasing energy prices in this paper we explore the multi dimensionality of the homeowners motivation to decide between competing rhs a questionnaire survey n 2440 conducted in 2010 among homeowners who had recently installed a rhs provides the empirical foundation principal component analysis shows that 25 items capturing different adoption motivations can be grouped around six dimensions 1 cost aspects 2 general attitude towards the rhs 3 government grant 4 reactions to external threats i e environmental or energy supply security considerations 5 comfort considerations and 6 influence of peers moreover a cluster analysis with the identified motivational factors as segmentation variables reveals three adopter types 1 the convenience oriented 2 the consequences aware and 3 the multilaterally motivated rhs adopter finally we show that the influence of the motivational factors on the adoption decision also differs by certain characteristics of the homeowner and features of the home

determinants of residential space heating expenditures in germany abstract we first examine the determinants of household expenditures on space heating and hot water supply in germany a number of socio economic characteristics of households are included along with building characteristics our analysis covers information on more than 12 000 households in germany for the years 1998 and 2003 the analysis continues by investigating whether different kinds of households are affected differently by increases in energy prices households in owner occupied properties are less affected compared to those in rented accommodation this could be because owners are more likely to have installed energy efficient heating and hot water supply systems and landlords have less of an incentive to improve the conditions of their rented accommodations an energy policy targeting especially the latter group might benefit not only households in rented accommodation but might also increase energy efficiency and reduce greenhouse gas emissions as well

designing an eu energy and climate policy portfolio for 2030 implications of overlapping regulation under different levels of electricity demand abstract the european union s current climate and energy policy has to operate under an ex ante unforeseen economic crisis as a consequence prices for carbon emission allowances in the eu emissions trading system collapsed however this price collapse may be amplified by the interaction of a carbon emission cap with supplementary policy targets such as minimum shares for renewables in the power sector the static interaction between climate and renewable policies has been discussed extensively this paper extends this debate by analysing the efficiency and effectiveness of a policy portfolio containing a cap and trade scheme and a target for a minimum renewable share in different states of aggregate electricity demand making use of a simple partial equilibrium model of the power sector we identify an asymmetric interaction of emissions trading and renewable quotas with respect to different states of aggregate electricity demand the results imply that unintended consequences of the policy interaction may be particularly severe and costly when aggregate electricity demand is low and that carbon prices are more sensitive to changes in economic activity if they are applied in combination with renewable energy targets our analysis of the policy interaction focuses on the eu yet the conclusions may also be of relevance for fast growing emerging economies like china

eu climate policy up to 2020 an economic impact assessment in its fight against climate change the eu is committed to reducing its overall greenhouse gas emissions to at least 20 below 1990 levels by 2020 to meet this commitment the eu builds on segmented market regulation with an eu wide cap and trade system for emissions from energy intensive installations ets sectors and additional measures by each eu member state covering emission sources outside the cap and trade system the non ets sector furthermore the eu has launched additional policy measures such as renewable energy subsidies in order to promote compliance with the climate policy target basic economic reasoning suggests that emission market segmentation and overlapping regulation can create substantial excess costs if we focus only on the climate policy target in this paper we evaluate the economic impacts of eu climate policy based on numerical simulations with a computable general equilibrium model of international trade and energy use our results highlight the importance of initial market distortions and imperfections as well as alternative baseline projections for the appropriate assessment of eu compliance cost

promoting renewable energy sources for heating and cooling in eu 27 countries abstract in addition to public policies aimed at improving the energy efficiency of buildings eu authorities have also promoted the use of renewable energy sources for heating and cooling uses res h c this paper analyses the main policy measures implemented in eu 27 countries up to 2009 i e subsidies tax incentives financial support and feed in tariffs twenty three member states mss have developed some of these policy measures the most widespread measure is the subsidy 22 mss have implemented these because from a political point of view subsidies provide a straightforward approach to promote the use of res h c secondly tax incentives have been used for reducing investment costs and making renewable energy profitable thirdly financial incentives and feed in tariffs have been used sparingly while financial incentives might be used more extensively for promoting res h c if they are accompanied by other policy measures feed in tariffs are not likely to be implemented significantly in the future because this measure is not designed for household heat producers

climate change adaptation a study of fuel choice and consumption in the us energy sector abstract using cross sectional data this paper estimates a national energy model of fuel choice by both households and firms consumers in warmer locations rely relatively more heavily on electricity rather than natural gas oil and other fuels they also use more energy climate change will likely increase electricity consumption on cooling but reduce the use of other fuels for heating on net american energy expenditures will likely increase resulting in welfare damages that increase as temperatures rise for example if the us warms by 5 c by 2100 we predict annual welfare losses of 57 billion

new market mechanism and its implication for carbon reduction in china abstract this article presents a detailed review and analysis of the discussions around the new market mechanism nmm and explores its potential in china it contributes to the current discussion of the nmm in three aspects first this article attempts to streamline ideas about the nmm the term nmm is considered to be an umbrella concept for emission trading systems which all parties can engage in on a voluntary basis in the implementation of their intended nationally determined contributions and which need to satisfy three criteria i having a large scale scope ii aiming to facilitate a net emission reduction iii allowing flexibility for the host country we also present a framework to clarify the nmm based on this framework major options with a high implementation potential are identified second we argue that the national level operational framework determines the chance of successful implementation of the nmm we identify different options based on a literature survey and evaluate them with respect to effectiveness and efficiency third we choose china a highly influential country regarding climate change polices as a case to analyze the potential contributions and challenges of the nmm and its implementation at different stages of national development

on the equivalence of bayesian and dominant strategy implementation we consider a standard social choice environment with linear utilities and independent one dimensional private types we prove that for any bayesian incentive compatible mechanism there exists an equivalent dominant strategy incentive compatible mechanism that delivers the same interim expected utilities for all agents and the same ex ante expected social surplus the short proof is based on an extension of an elegant result due to gutmann kemperman reeds and shepp 1991 we also show that the equivalence between bayesian and dominant strategy implementation generally breaks down when the main assumptions underlying the social choice model are relaxed or when the equivalence concept is strengthened to apply to interim expected allocations

the effect of house energy efficiency programs on the extensive and intensive margin of lower income households investment behavior abstract this paper examines the biggest house energy efficiency retrofit support program in greece which ran during 2011 2015 and approximately fifty thousand households participated we take advantage of an exogenous policy change resulting in cost reduction for households that occurred while the program was running this change substantially increased the subsidy rate for lower income households we find that this effective cost reduction increased the participation rate extensive margin we add to the literature on retrofits by further showing that this change increased substantially the investment amount intensive margin of these lower income households detailed data on a sub sample of households reveal that this increase was driven primarily by window replacement and thermal insulation investments

determinants of households space heating type a discrete choice analysis for german households abstract considering the increasing attention on efficient use of energy it becomes vitally important to understand the energy related behavior of households this article presents empirical evidence on the determinants of the space heating technology applied by a household three sets of variables are examined as potential influences building socio economic and regional characteristics to highlight both the differences and similarities the results are obtained from a sample of house owners and from a sample including all households the influence of socio economic factors is similar across these groups income is found to exert only a minor impact on the system choice dwelling features are significant in determining the heating type particularly in the sample including all households regional effects are important clear differences prevail between east and west germany

evolution of an aging society and effect on residential energy demand the development of an aged society paired with a growing number of elderly households is expected to increase residential energy demand this study is designed to analyze various factors which determine the energy demand of elderly households and to predict the future of residential energy consumption in an aging society in addition comparing the factors with those in western countries which contain a population of increasing age we try to clarify characteristics of the elderly and residential energy demand then propose possible future subjects for study

greenhouse gas abatement cost curves of the residential heating market a microeconomic approach in this paper we develop a microeconomic approach to deduce greenhouse gas abatement cost curves of the residential heating sector our research is based on a system dynamics microsimulation of private households investment decisions for heating systems to the year 2030 by accounting for household specific characteristics we investigate the welfare costs of different abatement policies in terms of the compensating variation and the excess burden we investigate two policies i a carbon tax and ii subsidies on heating system investments we deduce abatement cost curves for both policies by simulating welfare costs and greenhouse gas emissions to the year 2030 we find that i welfare based abatement costs are generally higher than pure technical equipment costs ii given utility maximizing households a carbon tax is the most welfare efficient policy and iii if households are not utility maximizing a subsidy on investments may have lower marginal greenhouse gas abatement costs than a carbon tax

assessing the design of three carbon trading pilot programs in china abstract to help overcome the challenge of growing co2 emissions china is experimenting with market based instruments including pilot co2 emissions trading systems etss in seven regions that serve as precursors of a national co2 ets implementing an ets in a rapidly growing economy in which government authorities exercise significant control over markets poses many challenges this study assesses how well three of the most developed pilot etss in guangdong shanghai and shenzhen have adapted carbon emissions trading to china s economic and political context we base our study on new information gathered through interviews with local pilot ets regulators and experts analysis of recent trading data and extensive legal and literature reviews we point out instances in which pilot regulators have deftly tailored carbon emissions trading to china s unique context and instances in which designs are insufficient to ensure smooth operation we also indicate areas in which broader institutional reforms of china s political economy may be required for carbon emissions trading to operate successfully we make nine recommendations to improve the design and operation of the pilot programs and to inform the construction of a national co2 ets

the impacts of liquidity dynamics on emissions allowances price different evidence from china s emissions trading pilots abstract the liquidities of china s emissions trading markets have significant impacts on emissions allowances price movement and pricing efficiency liquidity measures on illiquidity ratio and trade values indicate hubei emissions allowances hbea product has the highest liquidity shenzhen allowances sza and guangdong emissions allowances gdea products have the higher liquidity than beijing emissions allowances bea and shanghai emissions allowances shea products while tianjin emissions allowances tjea product has the lowest market liquidity in considered china s emissions trading pilots the dynamics of the illiquidity ratios for all selected emissions allowances products are negatively related with emissions allowances returns and trade volumes for bea tjea sza and hbea products are also negatively related with emissions allowances returns the dynamics of daily illiquidity ratios and trade based liquidity in beijing tianjin guangdong shenzhen hubei emissions pilots have significant volatility clustering impacts on the variances of regional emissions allowances returns previous market shocks of overnight and intraday price variations have the more persistent influences on the gdea returns than hbea returns reflecting greater inter day price ranges clustering effect

an ascending vickrey auction for selling bases of a matroid consider selling bundles of indivisible goods to buyers with concave utilities that are additively separable in money and goods we propose an ascending auction for the case when the seller is constrained to sell bundles whose elements form a basis of a matroid it extends easily to polymatroids applications include scheduling allocation of homogeneous goods and spatially distributed markets among others our ascending auction induces buyers to bid truthfully and returns the economically efficient basis unlike other ascending auctions for this environment ours runs in pseudopolynomial or polynomial time furthermore we prove the impossibility of an ascending auction for nonmatroidal independence set systems

estimation of residential electricity demand function in seoul by correction for sample selection bias abstract this paper attempts to estimate the residential electricity demand function in seoul to this end we collected the data from a survey of households in seoul and employed the bivariate model to rectify the undesirable impacts of non response data the results show that the size of family the size of house dummy for having a plasma display panel television dummy for having an air conditioner and the household s income have positive relationships with the residential electricity demand on the other hand electricity price contributes negatively to the residential electricity demand in addition the price and income elasticities were estimated as 0 2463 and 0 0593 respectively implying that residential electricity demand in seoul is price and income inelastic such useful information is expected to help policy makers regulate the residential electricity supply and predict the effect of the price on the residential electricity demand in the future

buy it now or take a chance price discrimination through randomized auctions increasingly detailed consumer information makes sophisticated price discrimination possible at fine levels of aggregation demand may not obey standard regularity conditions we propose a new randomized sales mechanism for such environments bidders can buy it now at a posted price or take a chance in an auction where the top d 1 bidders are equally likely to win the randomized allocation incentivizes high valuation bidders to buy it now we analyze equilibrium behavior and apply our analysis to advertiser bidding data from microsoft advertising exchange in counterfactual simulations our mechanism increases revenue by 4 4 and consumer surplus by 14 5 compared to an optimal second price auction this paper was accepted by assaf zeevi stochastic models and simulation

optimal pricing mechanisms with unknown demand the standard profit maximizing multi unit auction intersects the submitted demand curve with a preset reservation supply curve which is determined using the distribution from which the buyers valuations are drawn however when this distribution is unknown a preset supply curve cannot maximize monopoly profits the optimal pricing mechanism in this situation sets a price to each buyer on the basis of the demand distribution inferred statistically from other buyers bids the resulting profit converges to the optimal monopoly profit with known demand as the number of buyers goes to infinity and convergence can be substantially faster than with sequential price experimentation

electricity consumption in g7 countries a panel cointegration analysis of residential demand elasticities this article applies recently developed panel unit root and panel cointegration techniques to estimate the long run and short run income and price elasticities for residential demand for electricity in g7 countries the panel results indicate that in the long run residential demand for electricity is price elastic and income inelastic the study concludes that from an environmental perspective there is potential to use pricing policies in the g7 countries to curtail residential electricity demand and thus curb carbon emissions in the long run

electricity prices and consumers long term technology choices evidence from heating investments abstract this paper studies consumers s sensitivity to energy costs at the moment of making a long term energy technology investment the analysis exploits local variation in regulated electricity distribution prices that are persistent over time and therefore a good measure of long term price expectations price impacts are estimated on extensive administrative registry data of private persons acting as home builders in finland during 2006 2011 the results show that electricity prices notably influence builders choices and that electricity tax increases have induced demand for technologies based on renewable energy the results on the comprehensive set of individual level characteristics reveal that technology choices vary systematically across households current dwelling status and the education level have the strongest influence on the choice probabilities price sensitivity is found to be lower for low income households and to vary by the current dwelling status and type of building location

how people respond to contingent valuation questions a verbal protocol analysis of willingness to pay for an environmental regulation abstract this paper investigates what a respondent is thinking when answering a willingness to pay question in a contingent valuation using a think aloud technique from psychology called verbal protocol analysis the willingness to pay responses we observed seem to be constructed from a variety of considerations including an obligation to pay a fair share of the cost of the solution and signaling concern for a larger set of environmental issues the finding that respondents seem to construct their values at the time they are asked rather than reporting a more well defined value is seen as consistent with over two decades of research on the psychology of decision making potential uses of verbal protocols in contingent valuation studies are also discussed

emissions trading in china emerging experiences and international lessons grants by the robert bosch foundation under the program sustainable partners partners for sustainability the australian research council and the australian government supported different parts of the project

emissions targets and the real business cycle intensity targets versus caps or taxes for reducing greenhouse gas emissions intensity targets are attracting interest as a flexible mechanism that would better allow for economic growth than emissions caps for the same expected emissions however the economic responses to unexpected productivity shocks differ using a real business cycle model we find that a cap dampens the effects of productivity shocks in the economy on all variables except for the shadow value of the emissions constraint an emissions tax leads to the same expected outcomes as a cap but with greater volatility certainty equivalent intensity targets maintain higher levels of labor capital and output than other policies with lower expected costs and no more volatility than with no policy

public preferences for carbon tax attributes the impacts of climate change are already visible throughout the world recognizing the threats posed by climate change the durban platform the 17th session of the conference of parties cop 17 underscores that the global nature of climate change calls for the widest possible cooperation and ambitious action by all countries a crucial starting point for the design of effective and publicly acceptable policies is to explore public preferences for climate policy instruments using a choice experiment this study investigates public preferences for carbon tax attributes in a developing country context the results account for heterogeneity in preferences and show that turkish people prefer a carbon tax with a progressive cost distribution rather than one with a regressive cost distribution the private cost has a negative effect on the probability of choosing the tax earmarking carbon tax revenues increases the public acceptability of the tax moreover there is a preference for a carbon tax that promotes public awareness of climate change

strong duality for a multiple good monopolist we characterize optimal mechanisms for the multiple good monopoly problem and provide a framework to find them we show that a mechanism is optimal if and only if a measure derived from the buyer s type distribution satisfies certain stochastic dominance conditions this measure expresses the marginal change in the seller s revenue under marginal changes in the rent paid to subsets of buyer types as a corollary we characterize the optimality of grand bundling mechanisms strengthening several results in the literature where only sufficient optimality conditions have been derived as an application we show that the optimal mechanism for n independent uniform items each supported on c c 1 is a grand bundling mechanism as long as c is sufficiently large extending pavlov s result for two items pavlov 2011 at the same time our characterization also implies that for all c and for all sufficiently large n the optimal mechanism for n independent uniform items supported on c c 1 is not a grand bundling mechanism

carbon trading in a socialist market economy can china make a difference a global carbon trading system has gained shape since several major asia pacific economies declared their participation as the largest national source of greenhouse gases china is probably the most prominent newcomer pilot emission trading schemes are being introduced in this country with prospects for developing into a national scheme the initiative is primarily motivated by expected economic benefits rather than environmental commitments viability is uncertain due to the absence of a liberal political economic system as we know in the western world the theory of carbon trading is being tested in an unusual place with huge implications both practically and theoretically

the microeconometric approach to modelling energy demand some results for uk households the paper is concerned with the empirical modeling of domestic demand for energy at the level of the individual household a model of household energy expenditures and energy using durable ownership is described estimation takes place using a pooled sample of households drawn from the repeated cross sections of the annual family expenditure survey fes price and income elasticities are found to be highly dependent on individual household characteristics type of house tenure energy using durable ownership and outside temperature finally the results are placed in a policy relevant context copyright 1991 by oxford university press

the effects of climate policy on corporate technological upgrading in energy intensive industries evidence from china abstract the innovation effect is an important component when measuring the performance of environmental policy instruments based on a questionnaire survey this research has examined corporate energy conservation and emission reduction efforts in energy intensive industries in china under the pressure of different climate policies and in particular looked into their adoption of those technological innovation and diffusion activities the results show a large variety of corporate adoption of energy saving practical activities in general climate policies have played a greater role in promoting the adoption of managerial energy saving activities in respondent companies while comparatively their influences on the adoption of technology upgrading activities are relatively weak regulatory measures have exerted greater pressure and influence on corporate short term behavioural change as stated by the respondent companies however market based instruments show greater incentive effect in promoting adoption of energy conservation and emission reduction activities that refer to corporate long term oriented strategic planning or adjustment for instance they exert a significant incentive effect on increasing long term research and development investment for technological innovation and also play an important role in optimising corporate organisational structure the econometric analysis further proves the influences of market based instruments in promoting corporate adoption of technological innovation and diffusion activities

the economic impact of carbon pricing with regulated electricity prices in china an application of a computable general equilibrium approach we use a dynamic cge model sicge to assess the economic and climate impacts of emissions trading system ets in china with a carbon price of 100 yuan ton co2 a particular focus is given to the regulated electricity price regime which is a major concern of electricity sector s cost effective participation in ets in china we found 1 carbon pricing is an effective policy for china to reduce co2 emissions total co2 emissions reduction ranges from 6 8 to 11 2 in short term 2 rigid electricity price entails lower co2 emissions reduction but can be considered as a feasible starting point to introduce carbon pricing policies in short term as long as governmental subsidies are given to electricity production 3 in mid and long term the efficient policy is to earmark carbon revenue with competitive electricity price we propose to use carbon revenue to reduce consumption tax in the first year of the introduction of carbon price and to use the carbon revenue to reduce production tax in following years

energy consumption for space heating of west german households empirical evidence scenario projections and policy implications abstract both the technical characteristics of buildings e g insulation standards and the utilisation patterns of households are important determinants of the space heating demand of private households therefore this paper examines to what extent socio economic characteristics of households household size social position income etc are suitable to explain household s behaviour concerning space heating given technical building characteristics on the other hand energy efficiency factors derived from technical simulation models are scrutinised the empirical basis of this analysis is the official household survey 1988 for west germany containing about 44 000 data sets therefrom it turns out that the german insulation standards of buildings have been less effective in the past than assumed on the basis of technical simulations by means of scenario calculations projections of the heating energy demand for space heating in the future are obtained sketching the effect of different possible socio economic developments on the space heating consumption and analysing different political options concerning building insulation standards for new buildings and the existing building stock

multi item auctions a collection of items is to be distributed among several bidders and each bidder is to receive at most one item assuming that the bidders place some monetary value on each of the items it has been shown that there is a unique vector of equilibrium prices that is optimal in a suitable sense for the bidders in this paper we describe two dynamic auction mechanisms one achieves this equilibrium and the other approximates it to any desired degree of accuracy

an analysis of company choice preference to carbon tax policy in china abstract this paper summarizes an analysis of choice preferences of chinese companies to the design options of carbon tax policy the data were collected from 201 companies with around half of them based in the western shanxi province and the other half from the eastern jiangsu province modeling analysis of the discrete choice dataset confirms the statistically significant relationships between the company s preferences to carbon tax policy with the policy attributes including tax rate tax relief measures and the revenue utilization from the viewpoint of chinese businesses the option of carbon tax policy with tax rate at 10 30 yuan t co 2 allowing tax relief to energy intensive sectors using the revenues specific for climate change and starting as early as the 13th five year plan period 2016 2020 would be preferable and realistic the results of this research may be referred for the discussions and development of carbon tax policy in china

alternative approaches to cost containment in a cap and trade system we compare several emissions reduction instruments including quantity policies with banking and borrowing price policies and hybrid policies safety valve and price collar using a dynamic model with stochastic baseline emissions the instruments are compared under the design goal of obtaining the same expected cumulative emissions across all options based on simulation analysis with the model parameterized to values relevant to proposed us climate mitigation policies we find that restrictions on banking and borrowing including the provision of interest rates on the borrowings can severely limit the value of the policy depending on the regulator chosen allowance issuance path although emissions taxes generally provide the lowest expected abatement costs a cap and trade system combined with either a safety valve or a price collar can be designed to provide expected abatement costs near those of a tax but with lower emissions variance than a tax consistently a price collar is more cost effective than a safety valve for a given expected cumulative emissions outcome because it encourages inexpensive abatement when abatement costs decline

advancing the experiment to reality perspectives on shanghai pilot carbon emissions trading scheme shanghai as the most advanced mega city in china has launched a pilot carbon emission trading scheme sh ets that is designed to achieve a compromise between the domestic context in shanghai and a need for national policy appeal this paper gives an overview of the latest progress of the sh ets and sheds some light on the features of key design components such as the threshold for inclusion sector coverage cap setting allowance allocation and the monitoring reporting and verification mrv system based on a concern that manipulative principles and economic dynamics may lead to uncertainties and ultimately influence the emission reduction effect of the scheme this paper conducts an evaluation of potential uncertainties such as those caused by changes in patterns of economic growth strategic trading activities related to the bankable allowances carbon leakage risks and insufficient mrv capabilities to advance the experiment to reality this paper suggests some changes are made to the pilot which include adjusting the allowance allocation principles to facilitate change in the domestic energy structure improving the disclosure of emission data to guarantee information symmetry gauging the carbon leakage risks to strengthen compliance and introducing risk management for non regulated players and derivatives products

sectoral crediting mechanism how far china has to go abstract based on the review of the basic design of the sectoral crediting mechanism scm a promising option for developing countries emission reduction commitments this paper analyzes five important practical issues for china to solve before participating in scm which include 1 difficulties in determining a crediting baseline 2 the unsolved over supply problem in the carbon market 3 the very likely carbon credits falling short of mitigation costs problem 4 the immature market oriented price system jeopardizing the success of motivation incentives and 5 inadequate capacity building corresponding suggestions or compromise solutions are given after a discussion of each issue it is also recommended that in order to witness scm come into being researchers and negotiators should endeavor to solve the practical issues that scm meets now bearing in mind the balance of interests of both developing and developed countries finally we believe that scm s political barriers can be overcome when technical economic institutional and capacity problems are solved

auctions versus negotiations which is the more profitable way to sell a company an auction with no reserve price or an optimally structured negotiation with one less bidder we show under reasonable assumptions that the auction is always preferable when bidders signals are independent for affiliated signals the result holds under certain restrictions on the seller s choice of negotiating mechanism the result suggests that the value of negotiating skill is small relative to the value of additional competition the paper also shows how the analogies between monopoly theory and auction theory can help derive new results in auction theory jel d44 g34 there are close analogies between standard price theory and the theory of auctions in an absolute english auction in which the price rises continuously until only one bidder remains and the seller is required to accept the final bid the sale price equals the lowest competitive price at which supply equals demand in the theory of optimal auctions the seller is treated as a monopolist who can choose any

affordability of energy cost increases for korean companies due to market based climate policies a survey study by sector this paper estimates the affordability of energy cost increases for energy intensive companies due to the introduction of market based climate policies in korea data were collected from 62 respondents from iron steel cement and petrochemical industries over 90 of which are under control of the target management scheme an ongoing mandatory system limiting the greenhouse gases ghg emissions of large energy consuming entities the affordable energy cost increase was estimated using the multiple bounded discrete choice mbdc format results of which show that a mean energy cost increase of 2 6 is acceptable for all the entities sampled companies from the three sectors had similar affordability with an average acceptable energy cost increase of 2 5e2 8 the affordable policy induced energy cost in creases equate to carbon prices of 2500e4000 krw t co2 about 2 3e3 5 usd t co2 for the companies surveyed econometric analysis confirmed a strong correlation between energy price level and company ownership with cost affordability with a view to developing carbon tax policy and a domestic ghg emissions trading scheme in korea this research provides a basis from an industrial perspective for carbon pricing

company s affordability of increased energy costs due to climate policies a survey by sector in china this paper estimates the affordability of chinese companies on energy cost increases due to the introduction of market based climate policies the data were collected from 170 respondents mainly from iron and steel cement and chemical industries using a multiple bounded discrete choice mbdc format estimations indicate that a mean of 8 8 in energy cost increase would be acceptable for all the samples the chemical companies express a slightly higher affordability with the mean of acceptable ratios of energy cost increases being 9 9 while the cement companies show slightly lower affordability with a mean of 7 7 econometric analysis confirms that the market competition degree has a significant but negative relationship with the affordability while the company s size is significantly and positively associated with the affordability calculations indicate that the mean of affordable energy cost increases roughly equals a carbon price of 83 7 cny t co2 about 12 usd t co2 for chemical companies and around 40 cny t co2 about 6 usd t co2 for iron and steel and cement sectors this result provides a meaningful referendum for the development of carbon tax and the establishment of a domestic carbon emissions trading scheme in china especially from the perspective of surveyed industries

introducing the emissions trading system to china s electricity sector challenges and opportunities we examine the challenges and opportunities to introduce emissions trading ets in china s electricity sector in which the interaction between ets and electricity market reform plays a major role china s electricity sector is currently in a slow progress towards a more competitive and market based system both equal share dispatching policy and regulated wholesale and retail pricing policies pose significant challenges for implementation of ets in china s electricity sector one of the important points of ets is to give a price for carbon emissions and establish a cost pass through mechanism reminded that the essential of carbon pricing is to put a price on carbon emissions that is equal to discounted value of the external damages it should be regarded as a part of broader policy package for energy and resources price reform this will require that any low carbon power policy should be considered as a part of whole policy package aiming at further liberalizing the electricity sector in china three policy options are identified to incorporate ets with electricity reform under different circumstances a combination of those three options is also proposed to break the lock and reinforce the positive interaction between ets and the transition towards a competitive electricity system in link with current pilot ets designs a roadmap to introduce ets in a stepwise manner is suggested

sulfur dioxide control in china policy evolution during the 10th and 11th five year plans and lessons for the future china s central government established national goals to reduce sulfur dioxide so2 emissions by 10 in both the 10th and 11th five year plan periods 2001 2005 and 2006 2010 respectively but the early policies were unsuccessful at reducing emissions emissions increased 28 during the 10th five year plan after adapting a number of policies and introducing new instruments during the 11th five year plan so2 emissions declined by 14 we examine the evolution of these policies their interplay with technical and institutional factors and capture lessons from the 11th five year plan to guide future pollution control programs we find that several factors contributed to achievement of the 11th five year plan so2 reduction goal 1 instrument choice 2 political accountability 3 emission verification 4 political support 5 streamlined targets and 6 political and financial incentives the approach integrated multiple policy instruments market based command and control and administrative instruments specific to the chinese context the evolution of so2 reduction policies and programs has implications for further so2 reductions from power plants and other sources as well as control of other atmospheric pollutants such as nitrogen oxides nox and carbon dioxide co2 in china
