the pricing of options on assets with stochastic volatilities one option pricing problem that has hitherto been unsolved is the pricing of a european call on an asset that has a stochastic volatility this paper examines this problem the option price is determined in series form for the case in which the stochastic volatility is independent of the stock price numerical solutions are also produced for the case in which the volatility is correlated with the stock price it is found that the black scholes price frequently overprices options and that the degree of overpricing increases with the time to maturity one option pricing problem that has hitherto remained unsolved is the pricing of a european call on a stock that has a stochastic volatility from the work of merton 12 garman 6 and cox ingersoll and ross 3 the differential equation that the option must satisfy is known the solution of this differential equation is independent of risk preferences if a the volatility is a traded asset or b the volatility is uncorrelated with aggregate consumption if either of these conditions holds the risk neutral valuation arguments of cox and ross 4 can be used in a straightfoward way this paper produces a solution in series form for the situation in which the stock price is instantaneously uncorrelated with the volatility we do not assume that the volatility is a traded asset also a constant correlation between the instantaneous rate of change of the volatility and the rate of change of aggregate consumption can be accommodated the option price is lower than the blackscholes b s 1 price when the option is close to being at the money and higher when it is deep in or deep out of the money the exercise prices for which overpricing by b s takes place are within about ten percent of the security price this is the range of exercise prices over which most option trading takes place so we may in general expect the b s price to overprice options this effect is exaggerated as the time to maturity increases one of the most surprising implications of this is that if the b s equation is used to determine the implied volatility of a near the money option the longer the time to maturity the lower the implied volatility numerical solutions for the case in which the volatility is correlated with the stock price are also examined the stochastic volatility problem has been examined by merton 13 geske 7 johnson 10 johnson and shanno 11 eisenberg 5 wiggins 16 and

carbon subsidies taxes and optimal forest management we consider the effect of carbon credit payment schemes on forest owners land use and harvest decisions we study two possible credit allocation regimes one where credits are allocated according to the actual amount of carbon sequestered by the trees on a piece of land and another where credits are allocated according to the long run potential to sequester carbon on the land using a real options model with uncertain future timber prices we examine the effect on the timing of harvests and the replanting abandonment decision we show that both schemes discourage deforestation compensating growers for actual carbon sequestration leads to longer rotation periods between harvests while basing compensation only on the long run potential level of sequestration induces shorter rotation periods the former scheme leads to greater benefits of carbon sequestration at lower cost than the latter scheme although inducing moderate levels of sequestration is expensive under both schemes the cost falls dramatically when the level of payments climbs above some threshold indeed providing the payments are sufficiently generous carbon credit payment schemes offer an effective means of increasing carbon sequestration

swedish norwegian tradable green certificates scheme design flaws and perceived investment barriers abstract the eu commission recommends using market based support schemes for renewable electricity projects one example is the swedish norwegian tradable green certificate scheme we examine whether design features in the norwegian part of this scheme specifically the scheme s short duration and the way it is to be abruptly terminated contribute to investors perceptions of barriers we apply econometric techniques on primary data collected in two surveys of norwegian investors in hydropower and we use real options theory to predict and interpret investors responses we show that 1 immediately after the scheme was introduced investors are eager to lock in future subsidies by investing immediately and concerned with factors that may delay the completion of their projects 2 as the certificate deadline neared investors have become increasingly pessimistic and concerned with economic and risk barriers investors in big hydropower plants with regulation reservoirs are particularly concerned with the risk of not completing their projects in time to gain the right to sell certificates these findings are consistent with the predicted responses to the scheme design derived from real options theory in contrast to earlier studies we find no difference in responses to the scheme design across investor types

economy wide estimates of energy rebound effect evidence from china s provinces abstract the ongoing debate on the magnitude of china s economy wide energy rebound effect re entails further investigations not only with more details but also with more credible methods in this study a modified two stage approach which could avoid methodological issues regarding re estimation is applied to estimate macroeconomic re with a data panel of 30 provinces in china during the period 1997 2015 in particular in order to comprehensively measure energy efficiency we construct a dynamic energy efficiency indicator which considers not only the static efficiency of energy use but also the technical change regarding energy usage using dynamic panel data models we estimate the elasticity of energy consumption with respect to energy efficiency which directly links to the measurement of re the short run and long run estimates of re are reported and the 95 confidence interval was computed for each sample based on the nonparametric bootstrap method to further analyze the macroeconomic re of different regions results indicate that the average re of all provinces is 88 55 in the short run and the average long run re is 77 50 the re in the developed eastern region continuously decreased while re in the western region increased to be the largest during the research period

the energy rebound effect in china s light industry a translog cost function approach abstract china is in its industrialization and urbanization development stage which requires strong energy support with the largest population in the world the energy endowment of china is relatively small therefore energy conservation is one of the key tools for china s sustainable development and energy security when making policies for conservation the chinese government needs to deal with rebound effect carefully in 2012 china s light industry consumed 316 million tons of coal equivalents accounting for 9 percent of the country s total energy consumption which is about the total amount of energy consumed by south korea based on the translog cost function the magnitude of rebound effect in china s light industry is estimated for the first time using the dynamic ordinary least squares and seemingly unrelated regression methods considering the asymmetric effects of energy prices on energy consumption the rebound effect is approximately 37 7 and all the inputs are substitutes except for labor and energy the different magnitude of rebound effect between light and heavy industry is discussed and some policy implications are provided for more effective energy conservation allowing for the rebound effect

estimating direct and indirect rebound effects for u s households with input output analysis part 2 simulation abstract this is the second part of a two part paper that integrates economic and industrial ecology methods to estimate the indirect rebound effect from residential energy efficiency investments we apply the model developed in part one to simulate the indirect rebound given an estimate of the direct rebound using a 2002 environmentally extended input output model and the 2004 consumer expenditure survey in 2002 for the u s we find an indirect rebound of 5 15 in primary energy and co 2 e emissions assuming a 10 direct rebound depending on the fuel saved with efficiency and household income the indirect rebound can be as high as 30 40 in no x or so 2 emissions for efficiency in natural gas services the substitution effect modeled in part one is small in most cases and we discuss appropriate applications for proportional or income elasticity spending assumptions large indirect rebound effects occur as the u s electric grid becomes less carbon intensive in households with large transportation demands or as energy prices increase even in extreme cases there is limited evidence for backfire or a rebound effect greater than 100 enacting pollution taxes or auctioned permits that internalize the externalities of energy use would ensure that rebound effects unambiguously increase consumers welfare

estimating direct and indirect rebound effects for u s households with input output analysis part 1 theoretical framework abstract this is the first part of a two part paper providing an analytical model of the indirect rebound effect given a direct rebound estimate that integrates consumer demand theory with the embodied energy of household spending from environmentally extended input output analysis the second part applies the model developed in part one to simulate the direct and indirect rebound for the average u s household in terms of primary energy co2e nox and so2 emissions and for energy efficiency investments in electricity natural gas or gasoline services part one provides a critical review of the largely independent economic and industrial ecology literatures on the indirect rebound by studying the two goods case and the n goods case we demonstrate that the indirect rebound is bounded by the consumer budget constraint and inversely related to the direct rebound we also compare the common proportional spending and income elasticity spending assumptions with our model of cross price elasticities including both substitution and income effects for the indirect rebound by assuming zero incremental capital costs and the same embodied energy as conventional technologies for efficient appliances we model an upper bound of the indirect rebound future work should also consider the increase in consumer welfare possible through the rebound effect

the rebound effect for heavy industry empirical evidence from china abstract energy efficiency improvement will reduce the effective price of energy services and hence at least partially mitigate original expected energy conservation therefore the magnitude of rebound effect is important for the design and timing of an effective energy conservation policy under the framework of translog cost share equations we estimates the direct rebound effect for heavy industry in china for the first time by conducting an empirical research on the relationship between the direct rebound effect and the ease with which energy services can substitute for other inputs additionally asymmetric price responses are specified in the model for the rebound effect estimation empirical results in our paper indicate that the rebound effect for heavy industry in china is about 74 3 this reveals that energy efficiency improvement can save energy to a certain degree since the rebound effect is less than 100 back fire but most of the expected reduction in heavy industry energy consumption is mitigated these findings prove that energy pricing reforms and energy taxes should be further implemented to achieve effective energy conservation in china s 12th five years plan

comments on using latent variable approach to estimate china s economy wide energy rebound effect over 1954 2010 by shuai shao tao huang and lili yang abstract in a recent article shao et al 2014 formulate economy wide energy rebound effect based on the ipat equation and employ latent variable approach for estimation we argue that their formulation should be revised and advocate the distinguishment between energy efficiency improvement and technological progress for estimating energy rebound effect an application to estimate china s energy rebound effect over 1981 2011 is also provided

impacts of carbon based policy instruments and taxes on tropical deforestation the impacts of carbon payments and income taxes on curbing tropical forest loss are analyzed under a market equilibrium framework the supply of cleared forest land was derived by using a two period utility maximization model when the carbon sequestration of a private forestholder is credited the land demand was derived from the profit maximization problem of a cash crop farmer the model was applied to data from the humid chaco eco region of paraguay the results indicate that taxes on cash crop and forestry incomes may in fact be ineffective in curbing forest loss carbon payments however would effectively reduce forest clearing in the context studied a carbon payment of 30 per ton of carbon would limit deforestation to 10 of existing forest cover a reversible carbon crediting system in which a forestholder can redeem a credited forest seems to substantially increase at least in the short run the effectiveness of carbon payments carbon payments could also complement the tax on cash crop income in curbing tropical forest loss an effective policy to combat tropical deforestation should therefore jointly consider forestry and cash crop sectors

china s industrial energy consumption trends and impacts of the top 1000 enterprises energy saving program and the ten key energy saving projects abstract this study analyzes china s industrial energy consumption trends from 1996 to 2010 with a focus on the impact of the top 1000 enterprises energy saving program and the ten key energy saving projects from 1996 to 2010 china s industrial energy consumption increased by 134 even as the industrial economic energy intensity decreased by 46 decomposition analysis shows that the production effect was the dominant cause of the rapid growth in industrial energy consumption while the efficiency effect was the major factor slowing the growth of industrial energy consumption the structural effect had a relatively small and fluctuating influence analysis shows the strong association of industrial energy consumption with the growth of china s economy and changing energy policies an assessment of the top 1000 enterprises energy saving program and the ten key energy saving projects indicates that the economic energy intensity of major energy intensive industrial sub sectors as well as the physical energy intensity of major energy intensive industrial products decreased significantly during china s 11th five year plan fyp period 2006 2010 this study also shows the importance and challenge of realizing structural change toward less energy intensive activities in china during the 12th fyp period 2011 2015

international spillover and rebound effects from increased energy efficiency in germany the pollution energy leakage literature raises the concern that policies implemented in one country such as a carbon tax or tight energy restrictions might simply result in the reallocation of energy use to other countries this paper addresses these concerns in the context of policies to increase energy efficiency rather than direct action to reduce energy use using a global cge simulation model we extend the analyses of economy wide rebound from the national focus of previous studies to incorporate international spill over effects from trade in goods and services our focus is to investigate whether these effects have the potential to increase or reduce the overall global rebound of local energy efficiency improvements in the case we consider increased energy efficiency in german production generates changes in comparative advantage that produce negative leakage effects thereby actually rendering global rebound less than national rebound

investment in competitive equilibrium the optimality of myopic behavior there is an extensive literature on the optimal irreversible investment strategy of a solitary firm facing an exogenous price process this paper shows that the investment strategies that this literature derives may be optimal in competitive equilibrium even though the price process is now endogenous this provides a simple means for computing equilibrium investment strategies

exploring preference anomalies in double bounded contingent valuation double bounded dichotomous choice dbdc contingent valuation offers increased efficiency of willingness to pay wtp estimates compared with the single bounded format however evidence suggests dbdc generates anomalous respondent behaviour this paper provides the first investigation and explanation of these anomalies in health results suggest the incentives for truthful preference revelation are altered in the presence of a follow up question this result is found using both regression techniques and analysis of raw responses although findings suggest very certain respondents exhibit less anomalous behaviour inconsistencies remain across bounds the results of this study question the use of iterative valuation formats

a general equilibrium view of global rebound effects abstract how do energy efficiency gains affect energy consumption the effects are generally called rebound effects in the literature previous studies have extensively focused on only part of the global economy to study rebound effects e g energy consumption by households one industry or one country however since the global economy is highly connected among countries these studies may lead to misleading conclusions if the rebound effects in the rest of the economy are significant recently saunders 2008 analyzes the demand side by taking the global economy as a whole wei 2007 also provides a general analysis by using cobb douglas production functions for the global economy the present article expands wei 2007 general analysis to explore the rebound effects from an economist s viewpoint by taking the global economy as a whole and applying general forms of production functions the analysis provides new insights related to rebound effects we highlight the role of energy supply as a determinant of rebound we show that the substitution between energy resources and other productive resources is more relevant to long term rebound we predict that long term rebound may be lower than short term rebound and we also discover that super conservation can happen in both the short term and the long term

an empirical examination of the timing of land conversions in the presence of farmland preservation programs using a panel of parcel level data we estimate a hazard model and find strong evidence that the mere existence of an option to preserve farmland delays decisions to convert farmland to developed uses by about six years a reduction in median conversion time of 12 to 43 depending on parcel size where such delays allow local governments to improve infrastructure or implement stricter growth control measures benefits of a preservation option may be even more long term also increases in the variance of returns to development tended to slow conversion for parcels with all but the highest lot capacities copyright 2008 oxford university press

rural land use traditional agriculture or forestry the signing of the kyoto protocol and the official recognition of forestry s capacity to sequester carbon has prompted considerable interest within the european union in forestry as a competing land use application however despite large increases in grants to forestry afforestation rates in certain eu countries are below national targets in this paper we employ a real options model to theoretically explain why farmers may be slow to switch land from traditional agriculture to forestry the theoretical model is then used to motivate an empirical dynamic panel data model and both models are applied to irish data

defining the rebound effect abstract this paper gives rigorous definitions of the rebound effect not only in the well described single commodity case khazzoom 1980 the energy journal 1 4 21 40 but also for a multiple commodity case it is shown that the familiar laws for the single case do not hold for the multiple case the paper describes the state of the art of empirical estimation of the rebound effect with special focus on the estimates done for the netherlands we conclude that according to every definition empirical evidence shows that the re is probably small between 0 and 15

disentangling the effects of policy and payment consequentiality and risk attitudes on stated preferences abstract incentivizing respondents to truthfully reveal their preferences in stated preference surveys requires that they believe their survey responses can influence decisions related to the outcome in question policy consequentiality and that they will have to bear their share of the coercive cost if the outcome is implemented payment consequentiality we investigate the effects of these two aspects of perceived consequentiality on stated preferences in a field survey concerning renewable energy development in poland we find that beliefs in policy and payment consequentiality strengthen the respondents interest in having the project implemented however policy consequentiality decreases and payment consequentiality increases their sensitivity to the project cost which respectively increases and decreases their willingness to pay for the project we conclude that the two aspects of consequentiality should be addressed separately additionally we inquire the theoretically speculated links between the respondents perceptions of policy and payment consequentiality and their risk attitudes and we find no significant relationship

differentiated effects of diversified technological sources on china s electricity consumption evidence from the perspective of rebound effect abstract technological progress is an effective way to improve electricity efficiency due to the existence of the rebound effect it is of great significance to optimize the technical power saving policy by examining the rebound effect caused by different technological progress paths based on the panel data of electricity industry in 30 provinces of china from 1997 to 2013 this paper systematically examines the rebound effects of electricity consumption under the two sources of technological progress namely independent innovation and technology import then it discusses the impact of coal electricity linkage policy the empirical results are as follows 1 without considering rebound effect independent innovation significantly promotes electricity conservation while the effects of technology import is not obvious 2 when considering the rebound effect electricity price declining driven by independent innovation is not conducive to electricity saving while electricity price declining driven by technology import has an electricity saving effect 3 the coal electricity linkage policy that began in 2004 not only reduced the rebound effect by increasing the flexibility of electricity prices to a certain extent and improved the electricity saving effect of independent innovation but also reduced the electricity saving effect of technology import

what are the consequences of consequentiality abstract we investigate the extent to which dichotomous choice referenda responses are shaped by whether the individual believes the survey itself will ultimately impact policy using survey data from the iowa lakes project we test this supposition specifically we employ a bayesian treatment effect model in which the degree of perceived consequentiality measured as an ordinal response is permitted to have a structural impact on willingness to pay wtp for a hypothetical environmental improvement we test whether the estimated wtp distributions are the same for each value of the ordinal response in our survey data a subsample of individuals were randomly assigned supporting information suggesting that their responses to the questionnaires were important and will have an impact on policy decisions in conjunction with a bayesian posterior simulator we use this source of exogenous variation to identify the structural impacts of consequentiality perceptions on willingness to pay while controlling for the potential of confounding on unobservables we find evidence consistent with a knife edge result namely that the willingness to pay distributions are equal among those believing the survey to be at least minimally consequential and different for those believing that the survey is irrelevant for policy purposes

hypothetical versus real willingness to pay in the health care sector results from a field experiment abstract we conducted a field experiment comparing hypothetical and real purchase decisions for a pharmacist provided asthma management program among 172 subjects with asthma subjects received either a dichotomous choice contingent valuation question or were given the opportunity to actually enroll in the program three different prices were used us 15 40 and 80 in the hypothetical group 38 of subjects said that they would purchase the good at the stated price but only 12 of subjects in the real group purchased the good p 0 000 we cannot however reject the null hypothesis that definitely sure hypothetical yes responses as identified in a follow up question correspond to real yes responses we conclude that the dichotomous choice contingent valuation method overestimates willingness to pay but that it may be possible to correct for this overestimation by sorting out definitely sure yes responses

estimating direct rebound effects for personal automotive travel in great britain direct rebound effects result from increased consumption of cheaper energy services for example more fuel efficient cars encourage more car travel this study is the first to quantify this effect for personal automotive travel in great britain we use aggregate time series data on transport activity fuel consumption and other relevant variables over the period 1970 2011 and estimate the direct rebound effect from the elasticity of both vehicle and passenger kilometres with respect to a vehicle fuel efficiency km mj b the fuel cost of driving km and c road fuel prices mj we estimate a total of 108 models paying careful attention to methodological issues and model diagnostics taking changes in fuel efficiency as the explanatory variable we find little evidence of a long run direct rebound effect in great britain over this period however taking changes in either the fuel cost of driving or fuel prices as the explanatory variable we estimate a direct rebound effect in the range 9 to 36 with a mean of 19 this estimate is consistent with the results of us studies and suggests that around one fifth of the potential fuel savings from improved car fuel efficiency may have been eroded through increased driving we also show how the normalisation of distance travelled per capita per adult or per driver affects the results obtained

the effect of agricultural policies on land use and environmental quality in this paper i consider the environmental quality gains that may be achieved by reducing agricultural income supports a new methodology is developed to estimate land use shares in an application to wisconsin milk price support reductions result in shifts of marginal agricultural land to forest reducing soil erosion and providing off site water quality improvements the environmental benefits are estimated to be at least as large as the decreased welfare burden on consumers and taxpayers indicating a central role for environmental quality considerations in motivating policy reforms and a more efficient means of achieving the environmental quality goals of land retirement programs

analysis of electricity consumption in china 1990 2016 using index decomposition and decoupling approach abstract electricity consumption accounts for a significant portion of final energy consumption in countries worldwide and has a close relationship with economic growth this paper explores the factors influencing electricity consumption in china during 1990 2016 using index decomposition analysis and analyses the decoupling status between economic growth and electricity consumption in addition to the influencing factors these analyses are conducted at both national and sectoral levels the results reveal that 1 the economic activity effect was the main driving force increasing total electricity consumption in china while the energy intensity effect hindered it 2 both diversity and aggregation existed at the sector level the power generation chemicals and non ferrous sectors were the top three contributors to increased electricity consumption 3 the change of electricity consumption caused by gdp growth in china showed three decoupling states during 1990 2016 expansive negative decoupling expansive coupling and weak decoupling in particular the energy intensity effect stimulated the occurrence of decoupling 4 industrial sectors played a significant role in decoupling in china while service sectoral electricity consumption showed expansive coupling with its sectoral gdp in recent years

a view from the macro side rebound backfire and khazzoom brookes abstract this paper attempts to delineate a few key insights extracted from theoretical macroeconomic considerations of the rebound issue the goal has been to reduce these thoughts to a clear set of assertions that if true would be useful points of reference in the ongoing discussion despite their non empirical nature

rethinking economy wide rebound measures an unbiased proposal in spite of having been first introduced in the last half of the ninetieth century the debate about the possible rebound effects from energy efficiency improvements is still an open question in the economic literature this paper contributes to the existing research on this issue proposing an unbiased measure for economy wide rebound effects the novelty of this economy wide rebound measure stems from the fact that not only actual energy savings but also potential energy savings are quantified under general equilibrium conditions our findings indicate that the use of engineering savings instead of general equilibrium potential savings downward biases economy wide rebound effects and upward biases backfire effects the discrepancies between the traditional indicator and our proposed measure are analysed in the context of the spanish economy

does energy efficiency affect financial performance evidence from chinese energy intensive firms energy intensive firms are confronted with increasing pressure to improve energy efficiency and reduce energy consumption this paper explores the relationship between the energy efficiency and financial performance of a sample of firms in china based on a panel dataset for the period 2010 2014 six financial indicators representing the benefits of different stakeholders are used in the analysis our empirical results show that energy efficiency is positively related to return on equity return on assets return on investment return on invested capital and return on sales but has no significant relationship with tobin s q in addition we examine the interaction effect between energy intensity and firm growth and find that firm growth helps to enhance the positive relationship between energy intensity and financial performance our findings provide incentive for firms to be proactive in their efforts towards energy conservation and emissions reduction

production and spatial distribution of switchgrass and miscanthus in the united states under uncertainty and sunk cost abstract the u s cellulosic biofuel mandate has not been enforced in recent years uncertainty surrounding the enforcement of the mandate in addition to high production and harvest cost have contributed to a delay in the widespread planting of bioenergy crops such as switchgrass and miscanthus previous literature has shown that under uncertainty and sunk cost an investment threshold is further increased due to the value associated from holding the investment option in this paper we extend the previous literature by applying a real option switching model to bioenergy crop production first we calculate the county level break even price which triggers a switching away from traditional field crops corn soybeans and wheat to bioenergy crops under various scenarios differing by commodity prices production cost and biomass price expectations we show that the resulting break even prices at the county level can be substantially higher than previously estimated due to the inclusion of the option value in a second step we identify counties that are most likely to grow switchgrass or miscanthus by simulating a stochastic biomass price over time our results highlight two issues first switchgrass or miscanthus are not grown in the midwest under any scenario under low agricultural residue removal rates biomass crops are mostly grown in the southeast second under the assumption of a high removal rates bioenergy crops are not grown anywhere in the u s since the cellulosic biofuel mandate can be covered by agricultural residues

switching to perennial energy crops under uncertainty and costly reversibility we study a farmer s decision to convert traditional cropland into land for growing dedicated energy crops taking into account sunk conversion costs and uncertainties in crop returns the optimal decision rules differ significantly from the expected net present value rule which ignores uncertainties and from real options models that allow only one way conversion into energy crops these models also predict drastically different patterns of land conversions into and out of energy crops over time using corn soybean rotation and switchgrass as examples we show that the model predictions are sensitive to assumptions about stochastic processes of the returns government policies might have unintended consequences subsidizing conversion costs into switchgrass may not much affect proportions of land in switchgrass in the long run

a model of sequential investment abstract this paper specifies a model of a two stage sequential investment where the stages take time to complete it presents algebraic solutions for an individual firm s optimal sequential investment with costless suspension without suspension in the intermediate case of costly suspension and for aggregate investment with suspension the first stage trigger is below the second stage trigger for sufficiently long lags and high levels of output price uncertainty thus the firm may carry out exploratory investment we also evaluate the comparative statics of investment and show how the patterns of project costs and lags affect the incentive to invest

crop based biofuel production with acreage competition and uncertainty this paper examines the role of uncertain crude oil prices uncertain crop yields and competition for acreage on corn soybean and switchgrass prices under biofuel production mandates we find enforcement of the cellulosic mandate is costly in that it raises equilibrium prices of all three crops through competition for acreage however crude oil prices largely determine industry profitability even in the face of high crop prices further we find that uncertainty in crude oil prices and crop yields causes higher corn soybean and switchgrass prices compared to a baseline with no uncertainty

harvest decisions and asset valuation for biological resources exhibiting size dependent stochastic growth optimal harvest rules and preharvest valuation procedures are derived for biological assets with stochastic size dependent growth in a stochastic price environment these issues are analyzed as continuous time optimal stopping problems both the single rotation and ongoing rotations problems are addressed the sensitivity of harvest and valuation rules is assessed the results are compared with those derived from a myopic look ahead procedure and with the corresponding findings for age dependent growth copyright 1990 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

opportunity for profitable investments in cellulosic biofuels research efforts to allow large scale conversion of cellulose into biofuels are being undertaken in the us and eu these efforts are designed to increase logistic and conversion efficiencies enhancing the economic competitiveness of cellulosic biofuels however not enough attention has been paid to the future market conditions for cellulosic biofuels which will determine whether the necessary private investment will be available to allow a cellulosic biofuels industry to emerge we examine the future market for cellulosic biofuels differentiating between cellulosic ethanol and drop in cellulosic biofuels that can be transported with petroleum fuels and have equivalent energy values we show that emergence of a cellulosic ethanol industry is unlikely without costly government subsidies in part because of strong competition from conventional ethanol and limits on ethanol blending if production costs of drop in cellulosic biofuels fall enough to become competitive then their expansion will not necessarily cause feedstock prices to rise as long as local supplies of feedstocks that have no or low valued alternative uses exist then expansion will not cause prices to rise significantly if cellulosic feedstocks come from dedicated biomass crops then the supply curves will have a steeper slope because of competition for land

structural estimation of the stochastic dynamic decision problems of resource users an application to the timber harvest decision abstract this paper examines a method for structural estimation of the stochastic dynamic decision problems of resource users the method involves nesting a stochastic dynamic programming algorithm within a maximum likelihood routine an application to the timber harvest decision indicates that owners of slash pine plantations in southeast georgia use a low discount rate and treat timber price as a random walk moreover the harvest decision is apparently dominated by profit shocks overlooked in the usual models of the harvest decision

adjustment of consumers durables stocks evidence from automobile purchases this paper tests an optimal s s rule in household durable purchases and examines directly the resulting aggregate expenditure dynamics the observed decision rule responds to income uncertainty and growth as predicted by an s s model resulting from transactions costs tests against liquidity constraints find that about half the households purchase according to an optimal s s rule aggregating the s s rule over households produces a cross section distribution of durables holdings the empirical distribution is similar to that predicted theoretically as is its response to aggregate shocks furthermore simulations of aggregate expenditure based on the household distribution exhibit dynamics consistent with those observed in the 1980s

time to build option value and investment decisions abstract investment decisions and outlays are often made sequentially for example the rate at which construction proceeds is usually flexible and can be adjusted with the arrival of new information traditional discounted cash flow methods which treat the pattern of investment as fixed ignore this flexibility and understate the value of the project this paper uses contingent claims analysis to derive optimal decision rules and to value such investments we determine the effects of time to build opportunity cost and uncertainty on the investment decision for reasonable parameter values we show how a simple npv rule can lead to gross errors

mitigating hypothetical bias evidence on the effects of correctives from a large field study the overestimation of willingness to pay wtp in hypothetical responses is a well known finding in the literature various techniques have been proposed to remove or at least reduce this bias using about 30 000 responses on wtp for a variety of power mixes from a panel of 6500 german households and the fixed effects estimator to control for unobserved heterogeneity this article simultaneously explores the effects of two common ex ante approaches cheap talk and consequential script and the ex post certainty approach to calibrating hypothetical wtp responses based on a switching regression model that accounts for the potential endogeneity of respondent certainty we find evidence for a lower wtp among those respondents who classify themselves as definitely certain about their answers although neither cheap talk nor the consequential script corrective reduce wtp estimates receiving either of these scripts increases the probability that respondents indicate definite certainty about their wtp bids

economic hysteresis in hog production german hog production only responds in a very limited way to price fluctuations in the pork market the hog production concentrates on a few regions though it is not bound to special natural conditions such as soil quality furthermore the volume of production does not vary over time relatively high market risks sunk costs and the flexibility of the decision maker to defer investments characterize decision problems in hog production thus the real option approach is chosen to explain the inertia in production capacity by the use of panel data of specialized hog farms from the german farm accountancy data network an empirical investment model is estimated formally the model has the structure of a generalized ordered probit model this approach allows to test for economic hysteresis in the adjustment of hog production capacity the results confirm that uncertainty and flexibility widen the optimal range of inaction

energy rebound effect in china s industry an aggregate and disaggregate analysis abstract considering the crucial role of industrial sectors in energy conservation this paper investigates the impact of output growth on energy consumption in china s industrial sectors with an index decomposition model and the energy rebound effect in the industrial sectors with a panel data model using the annual data during 1994 2012 the empirical results indicate that first industrial output growth is proved to be the major factor in promoting industrial energy consumption while energy intensity reduction and structure shifts across industrial sub sectors play the dominant roles in slowing down industrial energy consumption second there does exist energy rebound effect in china s aggregate industry which ranges from 20 to 76 during 1995 2012 or 39 on average in particular the energy rebound effect in manufacturing is relatively smaller during the sample period i e 28 on average finally the energy rebound effect in both china s aggregate industry and manufacturing exhibit an overall decreasing trend over time

the causes of order effects in contingent valuation surveys an experimental investigation contingent valuation researchers have found that the hypothetical values respondents place on a nested sequence of environmental goods are sensitive to the order in which the goods are presented typically the smallest bundle of goods is valued more highly if presented first than if following more comprehensive bundles such effects appear even when each bundle is valued from an exclusive list or as an alternative to any other so that income and substitution effects are controlled we conduct lab experiments where participants are asked to value sequences of nested goods for purchase from an exclusive list using an incentive compatible becker degroot marschak mechanism we test whether order effects occur in valuation for a induced value goods b actual private goods and c identical private goods that are to be donated to charities we find significant order effects when the goods are valued for own use but not when they are valued for donation

insights on the effect of land use choice the perpetual option on the best of two underlying assets abstract we consider the effect of land use choice on speculative land value and on development timing as reflected in the optimal hurdle ratio which triggers immediate development we find that land use choice i e multiple use zoning may add over 40 to land value under typical economic circumstances the conditions for optimal development of the land become markedly more difficult to achieve higher hurdle ratio required when the two land uses have similar values indeed a rational indecision result obtains in theory development will never occur when the two land use choices have equal value

the macro economic rebound effect and the uk economy abstract this paper examines the macroeconomic rebound effect for the uk economy arising from energy efficiency policies 2000 2010 using the macroeconomic model mdm e3 the literature distinguishes between three types of rebound effect direct indirect and economy wide the macroeconomic rebound effect considered here is the combination of the indirect and economy wide effects policies for the domestic business commercial and public and transport sectors of the economy are analysed for 2000 2010 overall the policies lead to a saving of about 8 of the energy which would otherwise have been used and a reduction in co2 emissions of 10 or 14 mtc by 2010 there are also favourable macroeconomic effects lower inflation and higher growth we find that the macroeconomic rebound effect arising from uk energy efficiency policies for the period 2000 2010 is around 11 by 2010 averaged across sectors of the economy when this is added to the assumed direct rebound effect of around 15 this gives a total rebound effect of around 26 arising from these policies thus the findings of the study support the argument that energy efficiency improvements for both consumers and producers stimulated by policy incentives will lead to significant reductions in energy demand and hence in greenhouse gas emissions

irreversible abatement investment under cost uncertainties tradable emission permits and emissions charges abstract a major concern with tradable emission permits is that stochastic permit prices may reduce a firm s incentive to invest in abatement capital or technologies relative to other policies such as a fixed emissions charge however under efficient permit trading the permit price uncertainty is caused by abatement cost uncertainties which affect investment under both permit and charge policies we develop a rational expectations general equilibrium model of permit trading and irreversible abatement investment to show how cost uncertainties affect investment under permits we compare the resulting investment incentive with that under charges after controlling for the assumption that random shocks affect the abatement cost linearly we find that firms investment incentive decreases in cost uncertainties but more so under emissions charges than under permits therefore tradable permits in fact may help maintain firms investment incentive under uncertainty

empirical estimates of the direct rebound effect a review beginning with william stanley jevons in 1865 a number of authors have claimed that economically justified energy efficiency improvements will increase rather than reduce energy consumption jevons paradox is extremely difficult to test empirically but could have profound implications for energy and climate policy this paper summarises and critiques the arguments and evidence that have been cited in support of jevons paradox focusing in particular on the work of len brookes and harry saunders it identifies some empirical and theoretical weaknesses in these arguments highlights the questions they raise for economic orthodoxy and points to some interesting parallels between these arguments and those used by the biophysical school of ecological economics while the evidence in favour of jevons paradox is far from conclusive it does suggest that economy wide rebound effects are larger than is conventionally assumed and that energy plays a more important role in driving productivity improvements and economic growth than is conventionally assumed 2008 elsevier ltd all rights reserved

what experimental protocol influence disparities between actual and hypothetical stated values preferences elicited in hypothetical settings have recently come underscrutiny causing estimates from the contingent valuation method to bechallenged due to perceived hypothetical bias given that the receivedliterature derives value estimates using heterogeneous experimentaltechniques understanding the effects of important design parameters onthe magnitude of hypothetical bias is invaluable in this paper we addressthis issue statistically by using a meta analysis to examine data from 29experimental studies our empirical findings suggest that on averagesubjects overstate their preferences by a factor of about 3 in hypotheticalsettings and that the degree of over revelation is influenced by thedistinction between willingness to pay and willingness to accept publicversus private goods and several elicitation methods

options uncertainty and sunk costs an empirical analysis of land use change abstract in a real option model of land conversion incorporating return uncertainty and sunk costs optimal conversion thresholds are significantly higher than those from expected net present value models not accounting for these factors empirical tests of conversion from agriculture to forest suggest that landowners value the option to convert when making conversion decisions higher uncertainty in returns to all potential uses and lower correlation between shocks to agricultural and forest returns decreases the likelihood of conversion estimates indicate a significant impact on conversion decisions with approximations of option values ranging from 7 to 81 of the expected value of the land asset

an improved approach to estimate direct rebound effect by incorporating energy efficiency a revisit of china s industrial energy demand abstract the rebound effect or the response to energy efficiency improvement has drawn considerable attention from economists and policymakers however the magnitude remains quite controversial because of the differences in the definitions and methods being used originating from the definition of direct rebound effect we develop an improved approach incorporating energy efficiency the main advantages of the proposed approach are twofold first it enables us to estimate the demand elasticity of useful energy service with respect to energy service price the estimates are more consistent with the definition of rebound effect and are more effective second it decomposes direct rebound effect into substitution and output channels enabling us to further understand the microeconomic mechanisms applying this method we assess the direct energy rebound effect in china s industrial sectors we find that the direct rebound effect for the industry is 37 0 and the substitution and output channels contribute to 13 1 and 23 9 respectively substantial variations in the magnitudes and mechanisms occur by sector for heavy industry most energy rebound is induced by output expansion because of its sizeable cost decrease from efficiency improvements unlike heavy industry most energy rebound in light industry comes from substituting energy service for other inputs because firms in light industry are more flexible in adjusting production inputs our results provide evidences for the importance of energy efficiency measures and highlight the necessity of differentiated measures according to the sectoral characteristics

estimating the rebound effect in us manufacturing energy consumption abstract the energy price shocks of the 1970s are usually assumed to have increased the search for new energy saving technologies where eventual gains in energy efficiencies will reduce the real per unit price of energy services and hence the consumption of energy will rise and partially offset the initial reduction in the usage of energy sources this is the rebound effect which is estimated for the us manufacturing sector using time series data applying the dynamic ols method dols when allowing for asymmetric price effects the rebound effect is found to be approximately 24 for the us manufacturing sector

property tax policy and land use change in this study we analyze the effect of property taxes on changes between agricultural forestry conservation reserve program and developed land uses in louisiana we estimate a random parameters logit model of land use conversion from the national resources inventory plot data our results indicate that land use changes are inelastic with respect to property taxes simulation shows that current use valuation policy while slowing down development of rural lands also affects changes between rural land uses

option exercise games an application to the equilibrium investment strategies of firms under the standard real options approach to investment under uncertainty agents formulate optimal exercise strategies in isolation and ignore competitive interactions however in many real world asset markets exercise strategies cannot be determined separately but must be formed as part of a strategic equilibrium this article provides a tractable approach for deriving equilibrium investment strategies in a continuous time cournot nash framework the impact of competition on exercise strategies is dramatic for example while standard real options models emphasize that a valuable option to wait leads firms to invest only at large positive net present values the impact of competition drastically erodes the value of the option to wait and leads to investment at very near the zero net present value threshold copyright 2002 oxford university press

land price volatility in a geographically dispersed market historical evidence and theory lead to a hypothesis that land price variation increases with distance to market this hypothesis is tested with county data from five cornbelt states during the period 1969 to 1987 when price changes were unusually large our data support the hypothesis in the 70s prices increased more in the western cornbelt than in the eastern cornbelt in the 80s the western cornbelt experienced the more precipitous price declines our hypothesis explains why great plains farmers have experienced greater financial problems during times of stress than have many other farmers

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

the spillover effects of biofuel policy on participation in the conservation reserve program abstract this paper studies the spillover effects of rising biofuel production on participation in the conservation reserve program landowner participation decisions are modeled using a real options framework we develop a land use decision model that captures biofuel driven structural changes in market demand and derive threshold conditions that trigger participation in the program we then quantify the impacts of biofuel production on participation at both the national and state levels using monte carlo simulations the model is also used to analyze how changes in the persistence of the biofuel production boom and in the volatility of farming returns affect conservation participation decisions policy implications of the results are discussed

biological conservation in dynamic agricultural landscapes effectiveness of public policies and trade offs with agricultural production article i nfo land use change and land management intensification are major drivers of biodiversity loss especially in agricultural landscapes that cover a large and increasing share of the world s surface incentive based agri environmental policies are designed to influence farmers land use decisions in order to mitigate environmental degradation this paper evaluates the effectiveness of agri environmental schemes for biological conservation in a dynamic agricultural landscape under economic uncertainty we develop a dynamic ecological economic model of agricultural land use and spatially explicit population dynamics we then relate policies subsidies to grassland taxation of agricultural intensity to the ecological outcome probability of persistence of a species of interest we also analyze the associated trade offs between agricultural production in value and biological conservation in probability of persistence at the landscape scale

effects of cheap talk on consumer willingness to pay for golden rice a large body of literature suggests willingness to pay is overstated in hypothetical valuation questions as compared to when actual payment is required recently cheap talk has been proposed to eliminate the potential bias in hypothetical valuation questions cheap talk refers to process of explaining hypothetical bias to individuals prior to asking a valuation question this study explores the effect of cheap talk in a mass mail survey using a conventional value elicitation technique results indicate that cheap talk was effective at reducing willingness to pay for most survey participants however consistent with previous research cheap talk did not reduce willingness to pay for knowledgeable consumers

the effect of time to build on strategic investment under uncertainty we show that time to build which creates a lag between the decision to invest and production is an important element of industry structure we study a multiperiod investment game where there is demand uncertainty adding time to build to the model alters the classic tradeoff between making strategic commitments and exploiting the option to wait furthermore time to build gives rise to novel equilibria in which firms invest incrementally which contrasts with most prior work on multiperiod investment games in which firms invest only once we show how time to build affects firm heterogeneity investment timing the option value of waiting the evolution of prices and social welfare copyright 2003 by the rand corporation

the greenhouse effect the fallacies in the energy efficiency solution abstract the view that widespread improvements in energy efficiency can by themselves do anything to halt the build up of greenhouse gases around the globe is fundamentally unsound it is based on the same fallacies that underlie the claim that energy savings from improving efficiency can substitute for new energy supply the paper by keepin and kats1 claiming that per tonne of coal not burned improvements in energy efficiency are more cost effective than substituting nuclear for coal fired power is therefore an irrelevancy as far as this debate is concerned reductions is energy intensity of output that are not damaging to the economy are associated with increases not decreases in energy demand at the macroeconomic level even within the boundaries of their own flawed approach their attempt2 to refute the critique of their thesis made by jones3 was little more than misdirected grape shot with no discernable connected thread of argument

unintended impacts of public investments on private decisions the depletion of forested wetlands by affecting relative economic returns infrastructure investments can induce major changes in private land use the authors find that 30 percent of forested wetland depletion in the mississippi valley has resulted from private decisions induced by federal flood control projects despite explicit federal policy to preserve wetlands the model aggregates individual land use decisions using a parametric distribution of unobserved land quality dynamic simulations are used to quantify the impacts on wetlands of federal projects and other factors copyright 1990 by american economic association

rescaling contraction with a lower cost technology when revenue declines abstract a mature oil field rescaled contraction describes a switch to a technological alternative more appropriate for the depleted state of an underlying resource off shore oil rigs are an illustration since the original technological scale designed for very large output flows becomes inappropriate as the operational efficiency declines later in life and facing a dwindling output flow so a more appropriate extraction technology becomes economic a real option representation is formulated on a stochastic oil price and deteriorating output volume we consider investment divestment decisions both separately and jointly which have different implications for government policies and also option values the resulting model yields analytical or semi analytical results indicating that immediate switching to the lower cost technology could sometimes be hastened as the price volatility increases depending on the current revenue if divestment and switching are considered jointly however greater volatility could also promote hysteresis

using latent variable approach to estimate china s economy wide energy rebound effect over 1954 2010 the energy rebound effect has been a significant issue in china which is undergoing economic transition since it reflects the effectiveness of energy saving policy relying on improved energy efficiency based on the ipat equation and brookes explanation of the rebound effect this paper develops an alternative estimation model of the rebound effect by using the estimation model and latent variable approach which is achieved through a time varying coefficient state space model we estimate china s economy wide energy rebound effect over 1954 2010 the results show that the rebound effect evidently exists in china as a result of the annual average of 39 73 over 1954 2010 before and after the implementation of china s reform and opening up policy in 1978 the rebound effects are 47 24 and 37 32 with a strong fluctuation and a circuitously downward trend respectively indicating that a stable political environment and the development of market economy system facilitate the effectiveness of energy saving policy although the energy saving effect of improving energy efficiency has been partly realised there remains a large energy saving potential in china

impact of energy efficiency gains on output and energy use with cobb douglas production function abstract a special issue of energy policy 28 2000 was devoted to a collection of papers edited by dr lee schipper the collection included a paper entitled a view from the macro side rebound backfire and khazzoom brookes in which it was argued that the impact of fuel efficiency gains on output roughly gdp is likely to be relatively small by cobb douglas production function however an error in the analysis leads to under estimation of the long term impact this paper first provides a partial equilibrium analysis by an alternative method for the same case and then proceeds to an analysis on the issue in a two sector general equilibrium system in the latter analysis energy price is internalized both energy use efficiency and energy production efficiency are involved

enduring impacts of land retirement policies evidence from the conservation reserve program we examine the persistence of cropland retirements induced by the conservation reserve program crp the largest u s conservation program we analyze micro data on observed land use choices following crp contract expiration over 1995 1997 and predict that 42 of crp acres would not have been returned to crops within a year if the program had expired in 1997 these results indicate that temporary cropland retirement payments under crp generate land use changes that often extend beyond contract periods the analysis suggests that targeted signing bonuses for first time enrollees would increase the longer term impacts of crp and perhaps other incentive based land use programs

a general equilibrium assessment of rebound effects in this paper we use a general equilibrium model applied to a national economy norway to explore the potential for energy efficiency improvements to trigger economic forces that offset potential savings from using more efficient technologies rebound effects two types of energy efficiency improvements electricity and oil are introduced into various sectors of the economy our results suggest significant and surprising differences across sectors concerning both energy use and consequences for the build up of greenhouse gases rebound effects are found to be quite significant for manufacturing sectors since long term consumption of energy undergoes minor reductions or increases in response to efficiency improvements in other sectors rebound effects appear to be weak or almost absent

exploring the rebound effect from the perspective of household an analysis of china s provincial level abstract the existence of the energy rebound effect may partially even totally offset the expected energy savings in order to explore the status of the household rebound effect in china we manually compiled the provincial energy input output table of china then combining econometric methods input output analysis and the re spending model we conduct a detailed analysis of both the direct and indirect energy rebound effect from the household perspective in china under a unified research framework the results show there are significant differences in risk vulnerability regarding energy rebound effect among different regions qinghai is the most vulnerable province as 69 23 of its economic sectors could lead to a backfire effect two economic sectors have the potential to cause a backfire effect in thirteen provinces in addition the chinese government and its provincial government should take full account of the regional differences when formulating energy policies to alleviate the pressure on energy conservation and carbon emission reduction

supply of cellulosic biofuel feedstocks and regional production pattern interest in cellulosic biofuels has grown due to recent concerns about the impact of expanding production of corn ethanol on food prices and the greater potential of cellulosic biofuels to mitigate climate change the energy independence and security act eisa of 2007 limits the production of corn ethanol to 56 billion liters after 2015 and mandates the production of at least 80 of the 136 billion liters of ethanol from non corn starch based cellulosic feedstocks by 2022 the biomass research and development act of 2000 had established an even more ambitious goal of using biomass to replace the equivalent of 30 of current petroleum consumption by 2030 and estimated that this would require 1 billion dry short tons of biomass annually u s department of energy usdoe 2003 biomass can be obtained from several different sources including forest resources crop residues woody biomass and perennial grasses a usda usdoe report perlack et al 2005 examined the technical feasibility of sustaining this supply of biomass and the land resources that would be required under alternative scenarios with yield enhancing and other technological changes in conventional crops and perennial bioenergy crops the study estimated that 0 54 to 1 billion dry tons of agricultural crop based biomass could be obtained annually from cropland idle cropland and cropland pasture with moderate to high productivity gains in crop productivity residue collection and tillage practices

measuring energy rebound effect in the chinese economy an economic accounting approach estimating the magnitude of china s economy wide rebound effect has attracted much attention in recent years most existing studies measure the rebound effect through the additional energy consumption from technological progress however in general technological progress is not equivalent to energy efficiency improvement consequently their estimation may be misleading to overcome the limitation this paper develops an alternative approach for estimating energy rebound effect based on the proposed approach china s economy wide energy rebound effect is revisited the empirical result shows that during the period 1981 2011 the rebound effects in china are between 30 and 40 with an average value of 34 3

using cheap talk as a test of validity in choice experiments abstract in two experiments on the choice of consumer goods the estimated marginal willingness to pay for food is found to be lower in the survey version with cheap talk our test can be seen as a test of hypothetical bias this implies that we cannot reject the hypothesis of a hypothetical bias for marginal wtp in choice experiments

the intensity and timing of investment the case of land the authors model the decision to replace durable capital when intensity is variable decisions of this type include land redevelopment decisions where the density of residential or commercial development is a choice variable as well as capital replacement decisions where capacity is variable the authors provide a general yet simple formation of the problem using an optimal stopping framework they characterize the value of the project the timing of investment and the intensity of development the authors show that intensity interacts in important ways with timing taxes and project values the ability to vary intensity raises hurdle rents and delays development decisions copyright 1994 by american economic association

understanding technological progress and input price as drivers of energy demand in manufacturing industries in india abstract this paper presents a comprehensive analysis of energy demand behaviour of seven energy intensive manufacturing industries and the aggregate manufacturing sector in india during 1973 74 to 2011 12 the policy perform achieve and trade pat has mandated energy efficiency targets for these manufacturing industries in india we focus on two major drivers of energy demand technological progress and energy price productivity growth accounting and estimation of parametric cost function using annual survey of industry data bring out important implications regarding the role of these two drivers results suggest that these industries experienced technological progress over the study period 1973 74 to 2011 12 with significant energy saving bias during 1998 99 to 2011 12 increase in energy price has led to reduction in energy demand and augmented technological progress in most of the industries energy and material inputs are mostly substitutes during 1998 99 to 2011 12 productivity growth of energy input was induced by both technological progress and increase in energy price estimates of inter factor substitution suggest that price induced reduction in energy demand can be a capital intensive process in case of some industries rebound effect has never taken back full gains of energy efficiency policies in the context of these industries

getting more carbon bang for your buck in acre state brazil abstract acre state in brazil is at the forefront of efforts to institutionalize jurisdictional scale policies that aim to reduce emissions from deforestation and forest degradation redd given limited redd funds and uncertain returns from alternative land uses this paper estimates the minimum incentive payment acre s government would have to pay forest landowners in each of its 22 municipalities to ensure forest conservation despite lower profits but with lower conversion costs and more stable returns over time relative to corn and coffee production cattle pasture generates the highest returns in 19 municipalities municipalities are ranked according to their relative policy costs a ranking which is compared to the distribution of forest carbon stocks across acre finally the relative cost per tonne of carbon is derived which enables the identification of a group of 13 municipalities with the greatest potential for carbon bang for a given buck

a review of optimal energy policy instruments on industrial energy efficiency programs rebound effects and government policies abstract industrial energy efficiency programs ieeps are defined as one of the most popular government policies that aim to reduce energy consumption in industrial energy intensive sectors in this paper we review and classify the most important academic studies that have addressed the environmental and economic aspects of ieeps using a systematic review the classification of energy policy instruments has been developed based on an analytical approach we discuss also the outputs benefits and barriers of ieeps besides a comprehensive argument about the restrictive policies on the rebound effects made after the implementation of these programs the results disclose that china usa and sweden are the most addressed countries on ieeps and their applications in this regard incentive energy policies e g voluntary agreements and subsidies have been applied more than others in the last decade furthermore most of the reviewed studies emphasize energy price reform as an effective practical policy while a few analytical methods can be seen to help policy makers determine the optimal levels of decision variables finally according to the state of the art analysis the authors provide some novel recommendations to improve the performance of ieeps using some restrictive policies on the negative impacts of rebound effects

investment under uncertainty does competition matter abstract empirical applications of real options models in competitive environments implicitly exploit the optimality of myopic planning in a seminal paper leahy j v 1993 investment in competitive equilibrium the optimality of myopic behavior quarterly journal of economics 108 1105 1133 shows that the optimal investment strategy of a myopic planner who ignores market entries and exits of competitors as well as the resulting price effects constitutes a market equilibrium under rather general conditions as a result the calculation of optimal investment strategies is simplified considerably because competition does not have to be taken into account in this paper however we demonstrate by using simulation experiments that myopic planning may lead to non optimal investment strategies this is due to the fact that it is difficult or even impossible to specify the correct or equivalent price process for the myopic investor using real world data we quantify the degree of suboptimality and propose measures to reduce the error

using ex ante approaches to obtain credible signals for value in contingent markets evidence from the field while contingent valuation remains the only option available for measurement of total economic value of nonmarketed goods the method has been criticized due to its hypothetical nature we analyze field experimental data to evaluate two ex ante approaches to attenuating hypothetical bias directly comparing value statements across four distinct referenda hypothetical cheap talk consequential and real our empirical evidence suggests two major findings hypothetical responses are significantly different from real responses and responses in the consequential and cheap talk treatments are statistically indistinguishable from real responses we review the potential for each method to produce reliable results in the field

the macroeconomic rebound effect in china the rebound effect measures the fraction of an energy efficiency improvement that is offset by increased energy consumption a rebound effect can arise at both the microeconomic level and the macroeconomic level the macroeconomic rebound effect measures the effect of an increase in energy efficiency on overall energy demand after markets adjust and re equilibrate at the macroeconomic level energy efficiency gains can increase energy consumption through two channels the macroeconomic price effect and the macroeconomic growth effect in this paper we econometrically estimate the macroeconomic energy rebound effect in china our results show that there is a statistically significant macroeconomic price rebound effect for china for each province and for the short run intermediate run and the long run we also find some evidence of a macroeconomic growth rebound in the short run and the intermediate run for some years either nation wide or for some provinces in china moreover for some years and some provinces we cannot reject backfire the rebound effect is an important phenomenon that the government of china should not neglect when making energy policy as it affects how improvements in energy efficiency translate into changes in energy consumption
