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

weighing the costs and benefits of state renewables portfolio standards in the united states a comparative analysis of state level policy impact projections abstract state renewables portfolio standards rps have emerged as one of the most important policy drivers of renewable energy capacity expansion in the u s as rps policies have been proposed or adopted in an increasing number of states a growing number of studies have attempted to quantify the potential impacts of these policies focusing primarily on cost impacts but sometimes also estimating macroeconomic risk reduction and environmental effects this article synthesizes and analyzes the results and methodologies of 31 distinct state or utility level rps cost impact analyses completed since 1998 together these studies model proposed or adopted rps policies in 20 different states we highlight the key findings of these studies on the projected costs of state rps policies examine the sensitivity of projected costs to model assumptions evaluate the reasonableness of key input assumptions and suggest possible areas of improvement for future rps analyses we conclude that while there is considerable uncertainty in the study results the majority of the studies project modest cost impacts seventy percent of the state rps cost studies project retail electricity rate increases of no greater than 1 nonetheless there is considerable room for improving the analytic methods and therefore accuracy of these estimates

the demand for money in developing countries assessing the role of financial innovation traditional specifications of money demand have commonly been plagued by persistent overprediction implausible parameter estimates and highly autocorrelated errors the authors argue that some of these problems stem from the failure to account for the impact of financial innovation they estimate money demand for ten developing countries using various proxies for financial innovations they also assess the relative importance of this variable finding financial innovation can be better modeled as a stochastic random walk trend rather than a deterministic time trend financial innovation plays an important role in determining fluctuations of the demand for money the importance of this role increases with the rate of inflation

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

testing the liquidity effect with equilibrium interest rate we examine the existence of liquidity effects by using the equilibrium interest rates estimated from the disequilibrium analysis instead of the observed interest rate the use of equilibrium interest rates allows us to take the growth rate in the money supply as being exogenous and circumvent the identification problem away following the traditional ar model and the method proposed by hamilton 1997 we obtain evidences showing the negative relationship between the equilibrium interest rate and the growth rate in money supply

residential natural gas price affordability analysis a case study of beijing abstract in recent years the demand for natural gas has shown strong growth in china however the relative lack of domestic natural gas resources and dependence on gas imports have resulted in rising natural gas prices in order to ensure market order the natural gas pricing mechanism must be closely linked to customer affordability the objective of this paper is to analyse natural gas prices economic and psychological affordability for beijing s residents by the income expenditure elasticity model and the equivalent heating value method and further to evaluate the comprehensive affordability of the natural gas price by the small taking and interval number methods finally it provides some suggestions for the formulation of beijing s residential natural gas prices

analyzing public preferences and increasing acceptability for the renewable portfolio standard in korea abstract in order to respond to the challenge of climate change similar to other countries korea has announced various policies to vitalize the development and uptake of renewable energy the renewable portfolio standard rps is the most striking example of a policy in this area this study employs a conjoint survey and bayesian mixed logit model to analyze consumer preferences for specific attributes of the rps policy it analyzes households marginal willingness to pay mwtp for the rps with specific attributes and simulates the degree of household acceptability of the policy through a scenario analysis comparison between costs and benefits of implementing the policy is also attempted by analyzing the households mwtp with the actual transition expense of rps implementation incurred by electricity supply companies the simulation results provide implications for improving rps policy implementation households consider the creation of new jobs as the most important policy attribute followed by increase in electricity prices damage to forests reduction in co 2 emissions and length of power outages moreover the korean household is willing to accept an increase of up to 1 39 in its electricity prices relative to 2012 and the median mwtp of each household for rps implementation is krw 734 99 month usd 0 67 month

modeling the demand for narrow money in the united kingdom and the united states abstract despite the importance of well specified empirical money demand functions for inference forecasting and policy problems in modeling have arisen concerning the economic theories of money demand the data institutional frameworks financial innovation and econometric implementation by developing constant data coherent m 1 demand equations for the u k and the u s we investigate these issues and explain such puzzles as missing money the great velocity decline and the recent explosion in m 1 the endogeneity of money the lucas critique and the non invertibility of our m 1 models are also discussed

optimal investment portfolio in renewable energy the spanish case abstract this article presents a model for investing in renewable energies in the framework of the spanish electricity market in a way that risk is minimised for the investor while returns are maximised the model outlined here is based on an economic model for calculating cash flows intended to obtain the internal rate of return irr of the different energies being studied wind photovoltaic mini hydro and thermo electrical the irrs obtained are considered the returns on investments while their standard deviations are considered associated risks in order to minimise risk a comprehensive portfolio of investments is created that includes all of the available energies by means of a system of linear equations the solution of the linear system is graphically checked using the efficient frontier method for the different financing options several case studies within the renewable energies plan per is its spanish abbreviation that is in force in spain in the period 2005 2010 are analysed in order to illustrate the method as are other case studies using different types of financing helping us to reach the pertinent conclusions

a new unified approach to evaluate economic acceptance towards main green technologies using the meta analysis the aim of this paper is to analyze the main determinants of the economic acceptability of four green technologies gts alternative fuel vehicles energy savings in residential buildings smart meters and renewable electricity using a meta analysis on a sample of 35 selected papers which provided 245 primary data this approach allows detecting relationships across heterogeneous studies avoiding the subjectivity of qualitative surveys we implement a new two step procedure first we compute a measure of the implicit price for a kilogram of co2 avoided pco2 homogenizing the usable information for the gts considered second we conduct a meta regression using the computed pco2 values to estimate the socio economic determinants impact in general our results show a wide degree of acceptability for gts which is stronger among european citizens in particular it emerges that on average the estimated pco2 is positive for the gts considered and additional positive effects exist when respondents are confronted with an explicit reference to quantitative targets in terms of co2 abatement a clear proposal for payment timing and a specific renewable electricity mix these results indicate that information and transparency are crucial to spur gts deployment therefore to support gts market penetration public and private institutional stakeholders have to provide ad hoc information to the end users setting a clear and suitable system of prices to increase the economic value end users place on gts

willingness to pay lip service applying a neuroscience based method to wtp for green electricity abstract consumers willingness to pay wtp represents a central question for providers of renewable energy most studies on the subject have used contingent valuation and choice experiments however all empirical designs employed to date suffer from serious biases such as strategic behavior we introduce a novel neuroscience based approach to renewable energy related wtp research neuropricing which eliminates some of these biases we tested consumers wtp for two different green electricity products and found wtp for these products to be about 15 above that for a non green electricity tariff our results suggest that neuropricing is indeed able to eliminate strategic behavior moreover this approach allows for wtp studies with much smaller sample sizes than traditional methods require the neuroscience methodology can be used by researchers and marketers alike not only for testing the effects of product attributes on wtp but also for evaluating wtp effects of specific messages in marketing communications thus it may lead to a better understanding of consumer behavior and hence facilitate more successful marketing of renewable energy

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

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

the renewable portfolio standard design considerations and an implementation survey renewables have social and environmental bene ts compared to conventional electricity sources but are rarely competitive on a strict nancial cost basis this is because conventional sources are sometimes subsidized their full pollution costs are ignored and renewables involve newer higher cost technologies whose relative costs will fall with commercialization governments use several mechanisms to support renewables including direct nancial support grants loans indirect support r d demonstrations reform of nancial costs of conventional sources subsidy removal pollution taxes and the renewable portfolio standard rps the rps requires a minimum share of electricity from renewable energy sources its use is spreading because it maintains an incentive for renewable producers to reduce costs links the regulated market outcome to an environmental target and reduces government involvement although it is too early to evaluate fully its e ectiveness the survey for this study explored implementation issues in three european countries nine us states and australia and found the following the rps target is usually set to have environmental bene ts without causing signi cant price increases cost caps are sometimes used most jurisdictions limit eligibility to gridconnected domestic renewables the rps is usually applied to producers rather than consumers and to energy output not capacity flexibility mechanisms are desired but a challenge to implement administration in the us and australia is by government with delegation to independent utility regulators while in europe it is more the responsibility of government everywhere the rps is applied alongside other mechanisms of renewables support 2001 elsevier science ltd all rights reserved

econometrics and the design of economic reform the concept of economic reform is described as a planned shift from one pareto inefficient but quasi stable nash equilibrium or trap to a new pareto superior equilibrium which will also be stable the concept is applied to recent shock stabilization programs with special reference to israel where the economy was credibly shifted from a three digit inflationary process with considerable inertia to relative price stability with higher real growth at only moderate adjustment costs by means of a heterodox plan the idea is rationalized with a simple dual equilibrium inflation model for which some econometric estimates are also given copyright 1989 by the econometric society

economic effects by merger and acquisition types in the renewable energy sector an event study approach abstract this study classifies the types of mergers and acquisitions m a carried out in the renewable energy industry and explores their effects on enterprise value both the generalized autoregressive conditional heteroskedasticity and the ordinary least squares methodologies are used in an event study in order to improve the reliability of the presented analysis in order to understand how m a type affects enterprise value depending on the inter relationship between the acquirer and target business m a cases are divided into four groups homogeneous heterogeneous renewable heterogeneous energy and heterogeneous other from this analysis four implications can be drawn first homogeneous m a shows the biggest effect on enterprise value indicating that operating synergy and increasing market power are important factors when renewable energy firms undertake m a second m a with other industries of which financing companies take part in most show the second largest effect on enterprise value meaning that renewable energy is considered to have potential as an investment product further in the analysis of the wind power industry the result that heterogeneous other m a shows an even greater effect suggests that wind power is deemed to have a high potential for growth as an industry for investment lastly renewable energy m a in existing energy industries have negative effects on enterprise value indicating that strict regulations on the use of clean energy such as renewable energy result in energy companies incurring considerable costs

spatial heterogeneity and the choice of instruments to control nonpoint pollution because it is difficult to monitor emissions and to implement differentialtaxes and standards uniform taxes and standards on agricultural chemicaluse are often proposed and used to control nonpoint source pollution thisarticle analyzes the relative efficiency of these uniform instruments in thepresence of spatial heterogeneity we show that the relative slopes of themarginal pollution cost and marginal profit of chemical use are only one ofthe factors that affect the relative efficiency other factors includecorrelation between marginal pollution costs and marginal profits and theslope and variability of marginal profits in addition a uniform tax mayresult in some farmers not using the chemical and a uniform standard mayhave no effect on low input land we show empirically that the presence ofcorner solutions can reverse a conventional finding of tax or standardsuperiority based on the relative slop rule

spike models in contingent valuation spike models allow for a nonzero probability of zero willingness to pay in referendum style contingent valuation experiments they include many of the often used models as special cases and allow various analyses that are not possible in standard applications in this paper the economic rationale for the spike models and their estimation techniques are discussed and empirical illustrations are provided one study suggests that mean willingness to pay is zero and both studies strongly suggest that median wtp is zero these results have some bearing on the continuing debate of the incentive properties of hypothetical surveys and the construction of scenarios in contingent valuation experiments

contingent valuation controversies and evidence contingent valuation cv has become one of the most widely used non market valuation techniques cv s prominence is due to its flexibility and ability to estimate total value including passive use value its use and the inclusion of passive use value in benefit cost analyses and environ mental litigation are the subject of a contentious debate this paper discusses key areas of the debate over cv and the validity of passive use value we conclude that many of the alleged problems with cv can be resolved by careful study design and implementation we further conclude that claims that empirical cv findings are theoretically inconsistent are not generally supported by the literature the debate over cv however has clarified several key issues related to nonmarket valuation and can provide useful guidance both to cv practitioners and the users of cv results

choice of utility function form its effect on classification of risk preferences and the prediction of farmer decisions abstract in applications of expected utility analysis researchers are confronted with a choice among several utility functional forms subjective utility values and probability distributions for price and yield were elicited from sri lankan producers of minor export crops exponential quadratic and cubic utility functions were estimated the choice of functional form was found to affect both the classification of risk attitudes and the prediction of harvesting strategy the exponential function was the best predictor of harvesting strategy because it was the best predictor of mature harvesting all three functions were equally poor predictors of premature harvesting

renewable electricity as a differentiated good the case of the republic of korea this paper examines the willingness for korean consumers to pay a premium for renewable electricity under a differentiated good framework by applying the contingent valuation method korean consumers have been required to pay for their use of renewable electricity as of 2012 first we find that korean consumers recognise renewable electricity as a differentiated good from traditional electricity generated from fossil fuels or nuclear energy the mean willingness to pay to use renewable electricity is usd 1 26 per month second we confirm the existence of perfect substitution relationships among variant renewable technologies which suggests that korean consumers do not perceive them as differentiated goods one reason for this perception is that korean consumers are more inclined to favour economic feasibility over sustainability or the availability of the resource stock when choosing between renewable technology types in sum we can say that korean consumers recognise renewable electricity as a differentiated good but that they do not differentiate between variant renewable technologies thus the imposition of the cost of renewable electricity on consumers in the form of increased electricity charges would be acceptable to consumers as long as any price rise properly reflects their preferences

assessment of korean customers willingness to pay with rps abstract to increase the use of renewable energy the korean government will introduce the renewable portfolio standard rps in 2012 the rps places responsibility for extra renewable energy costs on the consumers and allows price competition among different renewable sources accordingly this study analyzes through the contingent valuation cv the willingness of korean households to pay more for electricity generated by wind photovoltaic pv and hydropower our empirical results show that although the willingness to pay or wtp was highest for wind power and lowest for hydropower the differences in wtp among the renewable sources were statistically insignificant this suggests that korean consumers prefer a renewable portfolio that minimizes power supply costs the average wtp for all three energy types was krw 1562 7 usd 1 350 per month per household which was approximately 3 7 of the average monthly electricity bill in 2010 this amount represents only 58 2 of what the korean government allocated in its budget to the new and renewable energy dissemination program in 2010 thus our results imply that the promotion of the new and renewable energy dissemination program may be difficult only with the wtp for electricity generated from renewable sources specifically the mean wtp will not support the set aside dissemination capacity for pv after 2014

financial services cointegration and the demand for money in israel the main hypothesis of this study is that ignoring the state of the financial services in the demand for money is a theoretical misspecification and is an important reason for the instability of the money demand as traditionally estimated a measurement approach for the state of the financial services is developed and applied to estimation of the demand for money in israel the approach presented in melnick 1990 is further developed by analyzing the lack of cointegration between real balances and their determinants according to theory as a case of omitted variables in a nonstationary time series set up when our measure for the state of the financial services is included it yields a stable cointegrated long run demand far money relationship the validity of steady state inflation tax analysis is questioned and a negative recommendation for the use of quantitative money targets is given copyright 1995 by ohio state university press

the economic value of south korea s renewable energy policies rps rfs and rho a contingent valuation study abstract amid growing environmental awareness the diffusion of renewable energy has attracted greater attention from both the public and policymakers to respond to global environmental concerns the korean government implemented a renewable portfolio standard rps in the electric power sector in 2012 it plans to introduce a renewable fuel standard rfs and a renewable heat obligation rho in the transportation and heating sectors in 2015 and 2016 respectively as such this study applies the contingent valuation method to elicit the willingness of korean households to pay more for their energy bills in order to support enforcement of these three policies the analysis considers the economic values of each individual policy as well as the aggregate value at the national level respondents mean willingness to pay for rps rfs and rho are estimated as 3287 5 4432 9 and 3971 1 korean won per month respectively these are equivalent to 5 8 1 5 and 2 0 respectively of current average monthly electricity transportation and heating expenses although all three policies appear highly feasible a cautious approach is necessary given the large proportion of respondents with zero willingness to pay furthermore although the level of willingness to pay for renewable electricity in korea has increased in recent years it remains low when compared to other leading countries such as japan

trendy solutions why do states adopt sustainable energy portfolio standards abstract thirty four states had adopted sustainable energy portfolio standards seps or similar goals by the end of 2008 with 14 adoptions since 2006 there appears to be something trendy about seps and states may adopt seps when internal variables would indicate otherwise this analysis extends the current discussion of seps adoption beyond internal variables relying on innovation and diffusion theory logistic regression with seps adoption as the dependent variable is used to test internal determinants and diffusion measures for the years 1997 2008 of the internal determinants variables affluence and government ideology were found to be positive and significant the results show that regional and neighbor diffusion variables are significant in seps adoption decisions even when accounting for ideological distance from previous adopters

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

willingness to pay for green electricity in korea a contingent valuation study abstract green electricity is energy that is generated from renewable energy sources such as solar power wind power small scale hydroelectric power tidal power and biomass power these sources mostly do not produce pollutants and are considered environmentally friendly however considering the current state of technology they are more costly government should take visible actions to compensate for the increased production costs this paper attempts to apply a contingent valuation cv method to obtain at least a preliminary evaluation of the benefits that ensue from the introduction of the policy that raises the percentage of green electricity consumption from 0 2 of the total electricity supply to 7 by 2011 overall the cv survey was successful in eliciting the willingness to pay wtp for green electricity considering that the cv method operated within respondents abilities to answer and the wtp estimates were statistically significant the monthly mean wtp estimates from parametric and non parametric methods were krw 1681 usd 1 8 and krw 2072 usd 2 2 respectively the estimates of the annual benefits to relevant residents amounted to krw 150 5 billion usd 157 5 million and krw 185 6 billion usd 194 2 million respectively

modelling zero values and protest responses in contingent valuation surveys in contingent valuation surveys the category of zero bidders refers to individuals that are not willing to pay anything for the programme under analysis specific questions can help to identify true zero values coming from people that are indifferent to the programme separately from protest responses the latter are generally excluded from the analysis this paper introduces a mixture sample selection model that takes into account both zero values and protest responses in the estimates the model is applied to the valuation of a traffic calming scheme aimed at reducing risks for residents in three villages in the north east of england

the role of question order and respondent experience in contingent valuation studies abstract grand canyon white water boating was used to address issues in contingent valuation of question ordering and respondent experience question ordering effects were not identified for experienced boaters but did occur in some estimates for less experienced boaters an experience effect is further suggested if respondents value their actual white water trips differently than written scenarios of trips no effect was identified for experienced boaters but a significant difference did occur for less experienced boaters significant differences for less experienced boaters suggest that respondent experience may play a role in value formation resulting in survey instrument effects in valuation estimates

information bias in contingent valuation effects of personal relevance quality of information and motivational orientation abstract a laboratory experiment examined the potential for information bias in contingent valuation cv consistent with the view that information about a public or private good can function as a persuasive communication willingness to pay wtp was found to increase with the quality of arguments used to describe the good especially under conditions of high personal relevance under low personal relevance wtp for a public but not for a private good was higher when an altruistic as opposed to an individualistic orientation was activated it is concluded that the nature of the information provided in cv surveys can profoundly affect wtp estimates and that subtle contextual cues can seriously bias these estimates under conditions of low personal relevance
