consumption betas and backwardation in commodity markets this paper examines the relationship between commodity consumption betas and realized commodity futures contract risk premiums a linear relationship between risk premiums and consumption betas is developed based on a consumption oriented capm the parameters of this linear model are estimated using fourteen commodities

measuring image spillovers in umbrella branded products umbrella branding the practice of labeling more than one product with a single brand name is commonly used by multiproduct companies spillovers occur when information about one product affects the demand for other products with the same brand name this article provides a methodology to analyze spillovers and uses it to measure two instances of spillover effects the study shows that negative spillovers resulted from the audi 5000 s problems with sudden acceleration and that positive spillovers resulted from jaguar s first major model change in seventeen years copyright 1990 by the university of chicago

price determination in the eu ets market theory and econometric analysis with market fundamentals abstract we investigate the price determination of the european union emission allowance eua of the european union emissions trading scheme eu ets we postulate an uncertain permit price and risk averse firms which have the possibility to hedge in the forward market the firms produce final goods abate their emissions and trade permits in the permit market the dependence of the equilibrium permit price on exogenous variables is studied in a permit market model we test our theoretical findings with empirical data from 2005 to 2010 in the eu ets market we use daily forward prices of eua as our dependent variable we use several econometric models with multiple stationary time series to discover that there is a strong relationship between the fundamentals such as german electricity prices and gas and coal prices with the price of eua we find that the eua forward price depends on fundamentals especially on the price of electricity as well as on the gas coal difference in a statistically significant way

who governs energy the challenges facing global energy governance this article conceptualizes the energy problems facing society from a global governance perspective it argues that a notion of global energy governance taken to mean international collective action efforts undertaken to manage and distribute energy resources and provide energy services offers a meaningful and useful framework for assessing energy related challenges the article begins by exploring the concepts of governance global governance and global energy governance it then examines some of the existing institutions in place to establish and carry out rules and norms governing global energy problems and describes the range of institutional design options available to policymakers it briefly traces the role of a selection of these institutions from inter governmental organizations to summit processes to multilateral development banks to global action networks in responding to energy issues and points out their strengths and weaknesses the article concludes by analyzing how the various approaches to global governance differ in their applicability to addressing the conundrums of global energy problems

corporate led sustainable development and energy poverty alleviation at the bottom of the pyramid the case of the cleancook in nigeria summary corporations are increasingly viewed as key actors in poverty alleviation bottom of the pyramid bop advocates suggest that multinational corporations mncs can simultaneously alleviate poverty and make profits by selling scaled down products to the poor our paper investigates this claim using the case of the cleancook stove and fuel technology introduced in nigeria by an mnc working through a nonprofit organization and local business actors supply and demand side analyses show that the cleancook is least likely to reach the energy poor bop households originally targeted the evidence suggests that serving the bop requires greater differentiation than can be achieved with profit driven business models

energy conservation policies in the oecd did they make a difference abstract in 1985 homes services automobiles truck freight air passenger traffic other transport and manufacturing in the oecd used 47 million bbl day of oil equivalent mb doe or 105 000 pj 1 between 1972 and 1985 however energy use per unit of activity in each of these sectors in the oecd fell significantly if these energy intensities by sector had been frozen at their 1972 values 1985 end use would have been close to 64 mb doe or 143 000 pj at the rates of activity that prevailed in each sector in 1985 2 the difference yields a saving of 17 mb doe the corresponding oil savings in this period amount to close to 12 mb doe including substitution by other fuels in this paper it is suggested that most of these savings will not reverse in the near time with lower oil prices only a small part was caused by energy conservation policies

pricing forward contracts in power markets by the certainty equivalence principle explaining the sign of the market risk premium in this paper we provide a framework that explains how the market risk premium defined as the difference between forward prices and spot forecasts depends on the risk preferences of market players and the interaction between buyers and sellers in commodities markets this premium is an important indicator of the behavior of buyers and sellers and their views on the market spanning between short term and long term horizons we show that under certain assumptions it is possible to derive explicit solutions that link levels of risk aversion and market power with market prices of risk and the market risk premium we apply our model to the german electricity market and show that the market risk premium exhibits a term structure which can be explained by the combination of two factors firstly the levels of risk aversion of buyers and sellers and secondly how the market power of producers relative to that of buyers affects forward prices with different delivery periods

can product demonstrations create markets for sustainable energy technology a randomized controlled trial in rural india abstract the literature on sustainable energy technology sees informational barriers as a major obstacle to technology adoption in the case of solar home systems recent studies report positive socio economic effects on households but technology adoption remains underwhelming in collaboration with a local solar technology provider we conduct a randomized controlled trial in 75 large villages in the state of uttar pradesh india to examine the ability of village solar demonstrations to create markets for solar home systems we find no effect of such demonstrations on technology sales awareness or perceptions of solar technology technology adopters report high levels of satisfaction with product quality and service suggesting that the null finding cannot be attributed to poor technology these findings suggest that lack of awareness is not a binding constraint on the growth of solar technology markets in the study area based on additional surveys we find evidence suggesting that access to credit from rural banks is an important explanation for variation in sales across villages these results do not prove that information and awareness are irrelevant in general but they show that even carefully designed marketing campaigns cannot increase demand for new products in the presence of a binding credit constraint

from linear fuel switching to multiple cooking strategies a critique and alternative to the energy ladder model abstract promoting sustainable development requires evaluating the technical and policy options that will facilitate the adoption and use of energy efficient and less polluting cooking stoves and practices the transition from traditional to modern fuels and devices has been explained by the energy ladder model that suggests that with increasing affluence a progression is expected from traditional biomass fuels to more advanced and less polluting fuels in this paper we evaluate the energy ladder model utilizing data from a four year 1992 96 case study of a village in mexico and from a large scale survey from four states of mexico we show that an alternate multiple fuel model of stove and fuel management based on the observed pattern of household accumulation of energy options rather than the simple progression depicted in the traditional energy ladder scenario more accurately depicts cooking fuel use patterns in rural households the multiple fuel model integrates four factors demonstrated to be essential in household decision making under conditions of resource scarcity or uncertainty a economics of fuel and stove type and access conditions to fuels b technical characteristics of cookstoves and cooking practices c cultural preferences and d health impacts this model also allows better estimates of the expected fuelwood demand and indoor air pollution in rural households

carbon pricing and electricity markets the case of the australian clean energy bill abstract we examine the impact of the clean energy bill on the price behavior of electricity futures contracts in the australian national electricity market first we compute ex ante forward risk premiums in the pre tax period until june 2012 then derive market implied expectations about additional costs of the carbon pricing mechanism cpm on generators as well as pass through rates during the carbon tax july 2012 june 2014 and post tax after july 2014 periods our results suggest that the observed carbon premiums became increasingly higher once the carbon tax had been proposed and subsequently legislated in 2011 during periods where market participants could be relatively certain that the tax would be effective we find expected carbon pass through rates between 67 and 150 which seem to be inversely related to emission intensities in the regional markets our results are also a clear indication of strong policy uncertainty with regards to the cpm and suggest that in the future a stable and long term policy framework would be required for a carbon pricing mechanism to have its full effect

demand for beef from cattle administered growth hormones or fed genetically modified corn a comparison of consumers in france germany the united kingdom and the united states we compare consumer valuations of beef ribeye steaks from cattle produced without growth hormones or genetically modified corn in france germany the united kingdom and the united states results suggest that french consumers place a higher value on beef from cattle that have not been administered added growth hormones than u s consumers however valuations of non hormone treated beef are statistically indistinguishable across germany the united kingdom and the united states results also suggest that european consumers place a much higher value on beef from cattle that have not been fed genetically modified corn than u s consumers copyright 2003 oxford university press

security justice and the energy crossroads assessing the implications of the nuclear phase out in germany abstract the nuclear melt down in fukushima resulted in diverging energy policy decisions across the world where germany decided to opt out of nuclear electricity production yet the government s decision making framework for energy policy decisions does not accurately reflect important drivers for the strategy change this paper presents the energy crossroads framework as a more comprehensive tool to analyse the drivers and impacts of the nuclear phase out 20 expert interviews were performed across business participants as well as policy makers in the national and international energy context results show that germany has adopted an environmental justice rather than energy security stance in their nuclear phase out policy with significant long term consequences

an econometric analysis of emission allowance prices knowledge of the statistical distribution of the prices of emission allowances and their forecastability are crucial in constructing among other things purchasing and risk management strategies in the emissions constrained markets this paper analyzes the two emission permits markets co2 in europe and so2 in the us and investigates a model for dealing with the unique stylized facts of this type of data its effectiveness in terms of model fit and out of sample value at risk forecasting as compared to models commonly used in risk forecasting contexts is demonstrated

understanding carbon lock in abstract this paper narrative argues that industrial economies have been locked into fossil fuel based energy systems through a process of technological and institutional co evolution driven by path dependent increasing returns to scale it is asserted that this condition termed carbon lock in creates persistent market and policy failures that can inhibit the diffusion of carbon saving technologies despite their apparent environmental and economic advantages the notion of a techno institutional complex is introduced to capture the idea that lock in occurs through combined interactions among technological systems and governing institutions while carbon lock in provides a conceptual basis for understanding macro level barriers to the diffusion of carbon saving technologies it also generates questions for standard economic modeling approaches that abstract away technological and institutional evolution in their elaboration the question of escaping carbon lock in is left for a future paper

a model for energy pricing with stochastic emission costs we use a supply demand approach to value energy products exposed to emission cost uncertainty we find closed form solutions for a number of popularly traded energy derivatives such as forwards european call options written on spot prices and european call options written on forward contracts our modeling approach is to first construct noisy supply and demand processes and then equate them to find an equilibrium price this approach is very general while still allowing for sensitivity analysis within a valuation setting our assumption is that in the presence of emission costs traditional supply growth will slow down causing output prices of energy products to become more costly over time however emission costs do not immediately cause output price appreciation but instead expose individual projects particularly those with high emission outputs to much more extreme risks through the cost side of their profit stream our results have implications for hedging and pricing for producers operating in areas facing a stochastic emission cost environment

household cooking fuels and technologies in developing economies abstract a major energy challenge of the 21 st century is the health and welfare of 2 7 billion people worldwide who currently rely on burning biomass in traditional household cooking systems this special issue on clean cooking fuels and technologies in developing economies builds upon an iaee workshop on this subject held in istanbul in 2008 foell et al 2008 it includes several papers from that workshop plus papers commissioned afterwards the major themes of that workshop and this special issue are analytical and decision frameworks for analysis and policy development for clean cooking fuels making energy provisioning a central component of development strategies strategies business models of suppliers of modern fuels and technologies analysis of successes failures of past policies and programs to improve access to clean cooking this introductory paper serves as a preamble to the 11 papers in this special issue it provides a brief background on household cooking fuels and technologies including 1 their implications for sustainable development health and welfare gender impacts and environment climate issues 2 options and scenarios for improved household cooling systems and 3 discussions of institutions programs and markets it closes with research and action agendas initially developed during the 2008 workshop

analyzing the functional dynamics of technological innovation systems a scheme of analysis various researchers and policy analysts have made empirical studies of innovation systems in order to understand their current structure and trace their dynamics however policy makers often experience difficulties in extracting practical guidelines from studies of this kind in this paper we operationalize our previous work on a functional approach to analyzing innovation system dynamics into a practical scheme of analysis for policy makers the scheme is based on previous literature and our own experience in developing and applying functional thinking it can be used by policy makers not only to identify the key policy issues but also to set policy goals

modeling eu allowances and oil market interdependence implications for portfolio management abstract this paper examines the dependence structure between european union allowances euas and crude oil markets during the second commitment period of the european union emissions trading scheme and the implications for portfolio management using different copula models our findings suggest positive average dependence and extreme symmetric independence that is consistent with interdependence and no contagion effects between the eua and crude oil markets the implication of this result for eua oil portfolios points to the existence of diversification benefits hedging effectiveness and value at risk reductions the eua market is therefore an attractive market for investors in terms of diversifying market risk and reducing downside risk in crude oil markets

the impacts of eu co2 emissions trading on electricity markets and electricity consumers in finland abstract in this paper the likely impacts of the eu emission trading system on the nordic electricity market and on the position of various market actors are assessed in its first phase the eu co 2 emission trading system includes power plants with thermal capacity greater than 20 mw metals industry pulp and paper industry mineral industry and oil refineries this paper describes the assessment done for the finnish minister of trade and industry analysing the likely impacts on power plant operators on energy intensive industries on other industries and on other consumer groups the impacts of emissions trading were studied with the vtt electricity market model and with the times energy system model the annual average electricity price was found to rise 0 74 eur mw h 1 for every 1 tonne co 2 1 in the nordic area large windfall profits were estimated to incur to electricity producers in the nordic electricity market in finland metals industry and private consumers were estimated to be most affected by the electricity market price increases expanded nuclear power generation could limit the increases in the prices of electricity to one third compared to those in the base case

valuing the influence of underlying attitudes and the demand for organic milk in japan subjective perceptions about a product affect consumer choice accordingly acquiring the underlying demand characteristics that consumers find desirable is vital for firms planning future marketing strategies however the extent to which product specific perceptions affect consumer choice is poorly understood new agricultural standards for organic livestock were introduced in japan in november 2005 and are expected to influence the market significantly choice modeling cm is used to explore how consumers evaluate the latent demands and conventional attributes or tangible values of organic milk the results suggest that latent demands along with socioeconomic characteristics and conventional attributes provide strong incentives for consumers to move from the purchase of conventional milk to organic milk the analysis indicates that latent demands reflecting the safeness of organic milk the better taste of organic milk the image of environmental friendliness in the production process and the image of the health and comfort of the cows are important factors that influence consumers purchasing decisions however each specific factor has a corresponding conventional tangible attribute that needs to be targeted in marketing strategy

why have improved cook stove initiatives in india failed summary an estimated 2 7 billion people cook meals on biomass fueled brick stone and clay stoves scarcity of wood and negative impacts on health and environment have motivated efforts to design and distribute improved cook stoves in developing countries in india adoption is limited despite massive promotion over many decades existing research suggests that many rural women in india do not want improved stoves and those who do face obstacles to adoption we step back from the many good case studies to examine the broader story of improved cook stoves ics in india we do so by bringing together technical research of applied science and narrative critique of social science rather than assuming a priori that traditional stoves require replacement we ask why indian cook stoves been a magnet for so much attention why adoptions rates have remained low and what lessons might be learned from a broad multi disciplinary perspective our approach is critical and reflexive given our own involvement in ic efforts and puts gender at the center our big picture review shows that the indian chulha for all its problems is a remarkably successful technology which also satisfies several important household needs hence targeting this device for obsolescence has profound implications that cannot be reduced to energy consumption or environmental hazards rural women do not prioritize ics but addressing their priorities requires either capital intensive investment or challenging powerful institutions in contrast ic interventions are relatively cheap decentralized mechanical and seemingly apolitical hence their popularity in development programs our review of chulha research leads us to reject both the optimism of development planners who frame such problems as technical and the antagonistic pessimism of their critics searching for a middle ground requires stepping back from the dogma of efforts to improve biomass cook stoves

modeling co2 emission allowance prices and derivatives evidence from the european trading scheme this paper studies the three main markets for emission allowances within the european union emissions trading scheme eu ets powernext nord pool and european climate exchange ecx the analysis suggests that the prohibition of banking of emission allowances between distinct phases of the eu ets has significant implications in terms of futures pricing motivated by these findings we develop an empirically and theoretically valid framework for the pricing and hedging of intra phase and inter phase futures and options on futures respectively

electricity markets volatility estimates regularities and risk management applications the recent deregulation of the market for electric power in many parts of the us and canada has expanded the set of potential tools for managing the types of risks faced by both generators and consumers of electric power in particular manufacturing and other firms whose operations are powered by electricity now face on a continuing basis the engineering management decisions concerning whether they should buy or produce electricity and if they are to buy or sell electricity what types of contracts are optimum these types of risk management decisions typically involve futures forwards options and other financial derivatives the price and volatility of electric power are known to play an essential role in determining which of these instruments should be used however electricity as a commodity possesses certain special features not shared by other commodities and hence its risk properties are not yet well understood in this paper we consider and test certain hypotheses about the properties of electricity price using recent market data we find that electricity prices possess certain volatility and other systematic properties that can be characterized by the type and method of delivery of electricity these properties can be used by firms in formulating their optimal demand and supply schedules of electric power

arresting the killer in the kitchen the promises and pitfalls of commercializing improved cookstoves summary in a shift exemplary of neoliberal approaches to development major funders of household energy interventions have begun to emphasize market based stove dissemination over partially subsidized models stove promoters are increasingly expected to operate as self sustaining businesses this shift is viewed as a way to scale up in order to reach millions of poor households lacking access to clean cooking technologies using the case of gira an ngo that has successfully distributed cookstoves in mexico s central highlands for nearly two decades we demonstrate how this trend presents challenges for organizations operating effectively with outside funding in highly contextual local conditions 2009 elsevier ltd all rights reserved

are electricity risk premia affected by emission allowance prices evidence from the eex nord pool and powernext the links between emission and energy markets are of great interest to practitioners academics and policy makers in this paper it is conjectured that a positive relationship exists between emission allowance spot returns and electricity risk premia within the european union emissions trading scheme eu ets we discuss how this can be justified on the basis of the substantial uncertainties in the carbon markets we also argue that this link could be due to trading strategies followed by electricity producers who attempt to exploit their initial allocation of free allowances analysis of data from three major markets the eex nord pool and powernext offers empirical support to our conjecture these findings have significant policy implications since they imply that efforts should be made in order to reduce the uncertainty in the carbon markets by clearly defining the eu ets regulative framework and design over the next years moreover our results suggest that the allocation of free allowances and their unrestricted trading enable electricity producers to accomplish windfall profits in the derivatives market at the expense of other market participants

do hypothetical and actual marginal willingness to pay differ in choice experiments application to the valuation of the environment abstract in this paper we test the validity of choice experiments with donations for environmental projects in particular we test whether or not there are differences in preferences between a hypothetical and an actual choice experiment our experiments indicate no differences in addition internal tests of validity indicate transitive and stable preferences in both experiments although there are some indications of possible learning effects during the experiment

the uniqueness of the energy security justice and governance problem this article argues that among all policy fields exhibiting externalities of a global scale energy stands out on four dimensions vertical complexity horizontal complexity higher entailed costs and stronger path dependency these structural attributes are at odds with contemporary key challenges of energy security energy justice and low carbon energy transition with regard to the latter energy governance challenges occur related to unclear levels of authority and weak resilience this has implications for energy scholarship specifically relating to the political economy of energy transitions discussions about common pool resources systems analysis and other neighboring disciplines

forecasting carbon futures volatility using garch models with energy volatilities abstract this article examines the volatility forecasting abilities of three approaches garch type model that uses carbon futures prices an implied volatility from carbon options prices and the k nearest neighbor model based on the results we document that garch type models perform better than an implied volatility and the k nearest neighbor model this result suggests that carbon options have little information about carbon futures due to their low trading volume we also investigate whether the volatilities of energy markets i e brent oil coal natural gas and electricity forecast following day s carbon futures volatility according to the results we suggest that brent oil coal and electricity may be used to forecast the volatility of carbon futures

influences from the european parliament on eu emissions prices abstract the decisions of the european parliament ep are shown to influence both eu emission allowance eua prices and volatility reductions in price and increases in volatility are observed when ep decisions are i not party political in origin ii made during times of low market sentiment or iii made during times of low market attention daily eua prices from 2007 to 2014 are used in the study with decisions analysed using an event study approach for price impact and a garch specification for volatility impact our findings suggest the need for policymakers to improve communication of long term strategies for the eua market this aims to reduce the evident ongoing uncertainty experienced by traders around each decision made by the ep the finding that sentiment and market attention at the time of an ep decision influences the market s reaction indicates a need to consider market dynamics in terms of decision timing so that market turbulence is not an unintended by product of an ep decision some form of medium term forward guidance may be called for

case study on initial allocation of shanghai carbon emission trading based on shapley value abstract carbon emission trading is an effective measure to reduce greenhouse gas emissions worldwide china has publicized plans to initiate the demonstration of carbon emission trading in seven regions as of 2013 initial allocation is fundamental but it proposes difficulty in the mechanism design of the carbon emission trading system benchmark grandfathering and the shapley value have been employed to simulate a specific case which consists of the initial allocation of carbon emission allowances of three power plants in shanghai china the results of the shapley value are regarded as a theoretical equitable reference the results of benchmark are similar to those of the shapley value however it is apparent that the allocation regarding grandfathering is inequitable considering other factors we proposed the following at the introduction of experimental stage free allocation pertaining to grandfathering can be adopted meanwhile benchmark should be prepared and adopted at the appropriate time furthermore a portion of the initial allowances can be reserved for auction and this portion for auction will escalate to the extent of 100 upon entering the formal stage in addition the tiered price mechanism and the subsidy policy are also suggested

beyond fuelwood savings valuing the economic benefits of introducing improved biomass cookstoves in the purepecha region of mexico article i nfo half of the world population relies on biomass for cooking with very significant health as well as climate change impacts improved cookstoves have been disseminated as an alternative to reduce these impacts however few detailed studies about the economic benefits of improved cookstoves ics interventions including environmental and health co benefits exist to date in this paper we perform a comprehensive economic evaluation of a dissemination program of ics in rural mexico the resulting cost benefit analysis cba of the patsari improved cookstove is presented utilizing estimation of direct costs and benefits including fuelwood savings income generation health impacts environmental conservation and reduction in greenhouse gas emissions the analysis is based on comprehensive data obtained through monitoring studies carried out in the study area from 2003 to the present results show that patsari cookstoves represent a viable economic option for improving living conditions of the poorest inhabitants of rural mexico with benefit cost ratios estimated between 11 4 1 and 9 1 the largest contributors to economic benefits stemmed from fuelwood savings and reductions in health impacts which constituted 53 and 28 of the overall benefit respectively

socio economic determinants of charcoal expenditures in tanzania evidence from panel data abstract compared to firewood charcoal is a relatively clean and convenient fuel nevertheless the mass production of charcoal can contribute substantially to deforestation rendering it imperative to regulate charcoal use this article uses nationally representative panel data on tanzania conducted in 2008 and 2010 to examine how charcoal expenditures change over time within any given household the focus of the analysis will be on identifying certain socio economic factors that affect charcoal use at the household level the framing of the analysis on variation in time within each household addresses the omitted variable bias that often undermines inference from comparisons across different households we find that while charcoal expenditures increase with household income the rise in charcoal use with income is relatively gradual household size is unrelated to charcoal expenditures but urban rural differences in fuel choice are large even though we include household fixed effects in all specifications in this regard policymakers and urban planners need to pay particular attention to the role of urbanization in predicting trends in charcoal expenditures in developing countries like tanzania

connective power solar electrification and social change in kenya summary market based rural electrification with solar energy is increasingly common in developing countries this article revolves around three main claims about solar electrification in kenya s unsubsidized market 1 the benefits of solar electrification are captured primarily by the rural middle class 2 solar electricity plays a modest role in supporting economically productive and education related activities but connective applications such as television radio and cellular telephone charging often receive a higher priority 3 solar electrification is more closely tied to increased television use the expansion of markets more rural urban communication and other processes that increase rural urban connectivity than to poverty alleviation sustainable development or the appropriate technology movement

estimating the commodity market price of risk for energy prices the purpose of this paper is to estimate the market price of risk mpr for energy commodities the ratio of expected return to standard deviation the mpr sign determines whether energy forward prices are upward or downward biased predictors of expected spot prices we estimate mprs using spot and futures prices while accounting for the samuelson effect we find long term mprs generally positive and short term negative consistent with positive energy betas and hedging respectively in spot electricity markets mprs in day ahead prices agree with short dated futures our results relate risk premia to informed hedging decisions and futures prices to forecast expected prices

conceptual proposals for measuring the impact of international regimes on energy security abstract the paper proposes two concepts to assess the effect of international regimes on energy security existing indicators focus mainly on state level factors excluding international influences international relation scholars on the other hand see a clear connection between international regimes and stable energy relations international regimes stabilise energy relations by providing frameworks for negotiations defining controlling and sanctioning compliance and allowing the actors to engage in package deals the researcher needs to include these factors in a complete assessment of political energy security risks as first step the paper uses the effectiveness of control mechanisms as basis for such consideration it refers specifically to international arbitration as the most important control mechanism in international energy relations the simplest measurement option is the share of a county s energy imports covered by a certain regime the paper applies the oslo potsdam solution to account for outcome effectiveness it applies a variant of the international regimes data base protocol to account for effective regime structures in a last section the paper proposes some possible paths for future research

paradoxes of decentralization water reform and social implications in mexico summary decentralized governance of water resources is a centerpiece of mexico s neoliberal reform strategy we analyze decentralization based on urban rural case studies in distinct geographical regions to ascertain whether it is linked to more efficient water management or sustainable use of water resources and to examine its development implications we assess whether or not private sector management is related to a more efficient sustainable and accountable management of water variety of municipal and private management arrangement in four urban areas we find that it has not resulted in efficiency or sustainability gains for agricultural water management irrigation districts in two case studies benefited from the more democratic participatory management by water users under mexico s transference strategy but did not result in greater equity efficiency or sustainability of water use we argue that decentralization in the mexican water sector is context specific and marked by limited benefits privatization is less an instrument aimed at improving efficiency than a channel for preferred treatment for capital accumulation by private entities as well as a legitimized way for the state to transfer the burden of water management to non state institutions the creation of new forms of water institutions requires not the retrenchment of the state but rather its involvement to ensure accountability transparency equity and sustainability

u s energy research and development declining investment increasing need and the feasibility of expansion investment in energy research and development in the u s is declining despite calls for an enhancement of the nation s capacity for innovation to address environmental geopolitical and macroeconomic concerns we examine investments in research and development in the energy sector and observe broad based declines in funding since the mid 1990s the large reductions in investment by the private sector should be a particular area of concern for policy makers multiple measures of patenting activity reveal widespread declines in innovative activity that are correlated with research and development r d investment notably in the environmentally significant wind and solar areas trends in venture capital investment and fuel cell innovation are two promising cases that run counter to the overall trends in the sector we draw on prior work on the optimal level of energy r d to identify a range of values which would be adequate to address energy related concerns comparing simple scenarios based on this range to past public r d programs and industry investment data indicates that a five to ten fold increase in energy r d investment is both warranted and feasible

market price of risk implied by asian style electricity options and futures in this paper we propose a jump diffusion type model which recovers the main characteristics of electricity spot price dynamics in the nordic market including seasonality mean reversion and spiky behavior we show how the calibration of the market price of risk to actively traded futures contracts allows for efficient valuation of nord pool s asian style options written on the spot electricity price furthermore we study the evolution of the market price of risk and the risk premium over a three year time period and compare the obtained results with those reported in the literature

trader types and volatility of emission allowance prices evidence from eu ets phase i abstract this paper studies the relation between the trading activity of market participants and the volatility of the european emission allowance price during phase i of the european union emission trading system eu ets we focus on the contrasting roles of different trader types we find evidence of a positive and significant trading activity volatility relation which appears to be stronger when accounting for trader type the positive relation can be mainly attributed to energy providers in contrast industrial companies seem to have traded more frequently when volatility levels were lower finally the non liable players represented by financial intermediaries appear to have acted as a flexible counterparty trading more with the energy sector when volatility was higher and more with the industrial firms when volatility was lower we discuss possible explanations for these contrasted positions understanding the trading activity volatility link is relevant for evaluating the efficiency of the eu ets although the relation is generally positive many players remained often inactive and traded mostly when volatility levels were lower policies targeting the engagement of less active players could lead to a smoother incorporation of information into prices and to an increase in market efficiency

letting the energy gini out of the bottle lorenz curves of cumulative electricity consumption and gini coefficients as metrics of energy distribution and equity energy services are fundamental determinants of the quality of life as well as the economic vitality of both industrialized and developing nations few analytic tools exist however to explore changes in individual household and national levels of energy consumption and utilization in order to contribute to such analyses we extend the application of lorenz curves to energy consumption we examined the distribution of residential electricity consumption in five countries norway usa el salvador thailand and kenya these countries exhibit a dramatic range of energy profiles with electricity consumption far more evenly distributed across the population in some industrialized nations than others and with further significant differences in the lorenz distribution between industrialized and industrializing economies the metric also provides critical insights into the temporal evolution of energy management in different states and nations we illustrate this with a preliminary longitudinal study of commercial and industrial electricity use in california during the economically volatile 1990s finally we explore the limits of lorenz analyses for understanding energy equity through a discussion of the roles that variations in energy conversion efficiency and climate play in shaping distributions of energy consumption the lorenz method which is widely employed by economists to analyze income distribution is largely unused in energy analysis but provides a powerful new tool for estimating the distributional dimensions of energy consumption its widespread use can make significant contributions to scientific and policy debates about energy equity in the context of climate change mitigation electric power industry deregulation and restructuring and the development of national infrastructure

putting their money where their mouths are consumer willingness to pay for multi ingredient processed organic food products in response to dramatically increasing adoption in consumer markets the national organic program nop initiated novel labeling standards for food products in the us in 2002 this program is a particularly relevant standardization effort for multi ingredient processed foods rather than a simple binary message organic or not gradations of organic content are now codified no existing published study evaluates consumer willingness to pay or motivation to purchase in response to such a rich organic label this article presents evidence of the impact of the nop through analysis of data collected in seven central ohio usa grocery stores results suggest that consumers are willing to pay premium prices for organic foods even those with less than 100 organic ingredients the magnitudes of wtp premia varied significantly among consumer groups suggesting that targeted marketing may be effective for organic merchandisers

risk premiums in the german day ahead electricity market this paper conducts an empirical analysis of risk premiums in the german day ahead electricity wholesale market we compare hourly price data of the european energy exchange eex auction and of the continuous over the counter otc market which takes place prior to the eex auction data provided by the energy exchange austria exaa has been used as a snapshot of the otc market two hours prior to the eex auction ex post analysis found market participants are willing to pay both significant positive and negative premiums for hourly contracts the largest positive premiums were paid for high demand evening peak hours on weekdays during winter months by contrast night hours on weekends featuring lowest demand levels display negative premiums additionally ex ante analysis found a strong positive correlation between the expected tightness of the system and positive premiums for this purpose a tightness factor has been introduced that includes expectations of fundamental factors such as power plant availability wind power production and demand hence findings by longstaff and wang 2004 can be supported that power traders in liberalised markets behave like risk averse rational economic agents

improved stoves in india a study of sustainable business models burning of biomass for cooking is associated with health problems and climate change impacts many previous efforts to disseminate improved stoves primarily by governments and ngos have not been successful based on interviews with 12 organizations selling improved biomass stoves we assess the results to date and future prospects of commercial stove operations in india specifically we consider how the ability of these businesses to achieve scale and become self sustaining has been influenced by six elements of their respective business models design customers targeted financing marketing channel strategy and organizational characteristics the two companies with the most stoves in the field shared in common generous enterprise financing a sophisticated approach to developing a sales channel and many person years of management experience in marketing and operations and yet the financial sustainability of improved stove sales to households remains far from assured the only company in our sample with demonstrated profitability is a family owned business selling to commercial rather than household customers the stove sales leader is itself now turning to the commercial segment to maintain flagging cash flow casting doubt on the likelihood of large positive impacts on health from sales to households in the near term

milk by any other name consumer benefits from labeled milk this article uses revealed preferences of consumers to study the consumer benefits from rbst free and organic labeled milk the article specifies and estimates a quadratic aids demand system model for different milk types using u s supermarket scanner data the introduction of rbst free and organic milk is used to estimate consumer benefits that are decomposed into two components competitive and variety effects results show significant consumer benefits from organic milk and to a lesser extent from rbst free milk based on the findings we explore implications for present u s labeling standards th eu s food sector is going through rapid transformations in terms of new product introduction and innovations organic and genetically modified gm food products are leading the way in changing the landscape of available choices to consumers this rapid expansion of product space has taken place concomitantly with an increase in public policy concerns on issues of standardization labeling health risks and associated consumer welfare in this paper we explore these broader issues in the context of a specific product introduction the introduction of recombinant bovine somatotropin rbst free and organic milk in the u s market from a policy perspective understanding the market for organics and the various components of that demand i e what portion is for gm free and what is for other attributes of organics can help determine the value of creating a national standard and the potential welfare losses to consumers of weakening such a standard are consumers willing to pay extra for organic and rbst free milk if so how

commercial use of upc scanner data industry and academic perspectives the authors report the findings from an exploratory investigation of the use of upc scanner data in the consumer packaged goods industry in the u s the study examines the practitioner community s view of the use of scanner data and compares these views with academic research forty one executives from ten data suppliers packaged goods manufacturers and consulting firms participated in wide ranging in person interviews conducted by the authors the interviews sought to uncover key questions practitioners would like to answer with scanner data how scanner data is applied to these questions and the industry s perspective regarding the success that the use of scanner data has had in each area the authors then compare and contrast practitioners views regarding the resolution of each issue with academic research this produces a 2 2 classification of each question as resolved or unresolved from the perspectives of industry and academia along the diagonal of the 2 2 issues viewed as unresolved by both groups are important topics for future research issues deemed resolved by both groups are correspondingly of lower priority in the off diagonal cells industry and academics disagree these topics should be given priority for discussion information exchange and possible further research practitioners reported that scanner data analysis has had the most success and been most widely adopted for decision making in consumer promotions i e coupons trade promotions and pricing for example logit and regression models applied to scanner data have revealed very low average consumer response to coupons which has directly led to reduced couponing activity managers also reported high levels of comfort with and impact from analyses of trade promotions and price elasticities while industry views most of the issues in these areas to be resolved academic research raises concerns about a number of practices in common commercial use these include price threshold analysis and trade promotion evaluation using baseline and incremental sales in product strategy advertising and distribution management practitioners reported that the use of scanner data has had more limited development success and impact in the case of new product decisions scanner data use has been slow to develop due to the inherent limitations of historicaldata for these decisions and a heavy reliance on traditional primary research methods in advertising scanner data is widely analyzed with models but confusion among practitioners is very high due to controversies about methods e g what level of data aggregation is best and conflicting results in distribution and retail management scanner data use has tremendous potential but a mixed track record to date thus practitioners view the use of scanner data as unresolved for most issues in product strategy advertising and distribution this view is largely though not entirely consistent with academic research which has only begun to address many of the key questions raised by practitioners in light of the large number of unresolved issues and mixed record of scanner data use to date the authors offer aseries of specific recommendations for immediate and long term research priorities that are likely to have the greatest impact on commercial utilization of upc scanner data topics of immediate priority include price thresholds and gaps baseline and incremental sales base price elasticity competitive reactions measurement of advertising effects management of brand equity rationalization of product assortments and category management long term priorities include a greater emphasis on profitability versus sales or market share developing prescriptive models versus descriptive models and the need for industry standards

concentration in the european electricity industry the internal market as solution abstract this article offers an analysis of the present competitive and regulatory framework of the european electricity sector and the results achieved with the liberalisation process considering the reactions of incumbents to the liberalisation the focus in this work is mainly on the problem of market concentration in the sector the new trends toward the creation of national champions as well as recent mergers between gas suppliers and electricity producers raise serious concerns about abuses of market power and risk of future collusion in particular the strategic linkage of existing markets and the expansion into new ones are analyzed in the light of the multimarket contact theory considering investment in interconnection among member states the internal market issue is investigated as a solution to the risks coming from liberalisation

a public choice view on the climate and energy policy mix in the eu how do the emissions trading scheme and support for renewable energies interact abstract in this paper we analyze the rationale for an energy policy mix when the european emissions trading scheme ets is considered from a public choice perspective that is we argue that the economic textbook model of the ets implausibly assumes 1 efficient policy design and 2 climate protection as the single objective of policy intervention contrary to these assumptions we propose that the ets originates from a political bargaining game within a context of multiple policy objectives in particular the emissions cap is negotiated between regulators and emitters with the emitters abatement costs as crucial bargaining variable this public choice view yields striking implications for an optimal policy mix comprising res supporting policies whereas the textbook model implies that the ets alone provides sufficient climate protection our analysis suggests that support for renewable energies 1 contributes to a more effective ets design and 2 may even increase the overall efficiency of climate and energy policy if other externalities and policy objectives besides climate protection are considered thus our analysis also shows that a public choice view not necessarily entails negative evaluations concerning efficiency and effectiveness of a policy mix

umbrella branding as a signal of new product quality an example of signalling by posting a bond i present a signalling model in which a multiproduct firm can use its reputation as a bond for quality by using a brand name for an established product when it introduces a new experience good as out of equilibrium beliefs are specified a false signal may be taken to imply that both the established and the new product are of low quality in contrast the absence of a signal leaves open the possibility that one of the two products is of high quality hence the signal can be credible without excessive sunk costs as long as the bond posted is sufficiently large

conceptualizing urban household energy use climbing the energy services ladder this article begins by defining energy services and identifying how they differ according to sector urban and rural areas and direct and indirect uses it then investigates household energy services divided into three classes lower income middle income and upper income it finds that the primary energy technologies involved with low income households involve a greater number of fuels and carriers ranging from dung and fuelwood to liquefied petroleum gas and charcoal but a fewer number of services middle income households throughout the world tend to rely on electricity and natural gas followed by coal liquefied petroleum gas and kerosene these homes utilize energy to produce a much broader range services the upper class or rich have access to the same energy fuels carriers and technologies as middle income homes and families but consume more energy and more high luxury items the study highlights how focusing on energy services reorients the direction of energy policy interventions that energy services are neither uniform nor innate and by noting exciting areas of potential research

a political economy perspective on technology innovation in the kenyan clean cookstove sector abstract in kenya as in many sub saharan african countries clean cookstoves are promoted as a solution to various health environmental and livelihood challenges after decades of programs there is a need to better understand if clean cookstoves are really transforming household energy use and if not why not combining theory from technological innovation systems literature and political economy the article highlights key weaknesses in the sector and offers explanations for the limited success of efforts to introduce clean cookstoves to date clean cookstoves remain a nascent innovation system in kenya its main weaknesses being lack of strategic direction low levels of legitimacy among government and consumers and weak knowledge accumulation and learning in the absence of meaningful government engagement technological choices and business models are influenced by the interests and norms of external actors including a stronger emphasis on health outcomes than other livelihood or environmental benefits going forward achieving a transformation in cooking energy use will depend on what role national and county governments play fiscal incentives introduced in 2016 and work on the country s sustainable energy for all action plan are early signs of greater engagement with household energy challenges

emergence of financial markets for electricity a european perspective abstract deregulation directed at european energy markets is proceeding although the speed often may seem slow real changes are coming in the development of physical and especially financial markets for electricity electricity deregulation started in individual countries notably the united kingdom and norway and the norwegian effort spread to the rest of the nordic region before the union s 1996 electricity directive started to have a real impact electricity deregulation is a complicated process involving breaking up of generation monopolies unbundling of generation and transmission consumer choice of suppliers through local distributors and eventually perhaps the establishment of a power pool where physical as well as financial contracts are traded the deregulation process now has gone far enough to reap some experiences the original uk deregulation model which focused mainly on breaking up the generation monopoly proved somewhat inefficient because it didn t offer real consumer choices and opened for inefficient gaming strategies among producers this experience has pushed the united kingdom in the direction of the nordic model norwegian deregulation is peculiar in the sense that new entry to generation is highly restricted on the other hand norway now with the entire nordic region has developed a quite advanced and quite well functioning electricity trading pool with widespread financial trading and good liquidity part of the success of the nordic model comes having a high quality spot price which can be used as a benchmark for the pricing of financial contracts another possible source of success is the high proportion of hydropower for which production volumes can be adjusted quickly and outages and price spikes thus avoided the swiss experience further underscores the importance of a spot price benchmark because the extensive swiss physical trade has allowed a growing volume of contract trade even in the absence of deregulation from these experiences we propose four factors we believe to be instrumental in creating healthy financial power markets the choice of pool model including spot adjustment and forward markets will make or break liquidity a price index is essential for ensuring transparency standardized simple derivative contracts make trading easier and more attractive finally the underlying physical system is important a hydro based system is easy to adjust while a thermal system will have problems with security of supply although the process is slow deregulation is likely to change the european electricity market in profound ways we see the effects mostly as beneficial deregulation will improve efficiency in generation will improve transparency for better consumer choices and allow the emergence of efficient financial trade in electricity if deregulation is all that s done the environmental effects may be adverse because lower prices encourage greater consumption and hence emissions coupled with a sensible environmental policy we believe deregulated markets can minimize the costs of environmental protection

dynamic behavior of co2 spot prices co2 emission allowances are traded nowadays over the counter otc and on exchanges across the european union eu it thus becomes increasingly important for traders of these emission certificates to have a valid co2 spot price model to value potential derivatives in addition co2 emitting companies require an adequate co2 spot price model in order to better assess their production costs and support emissions related investment decisions however sufficient price history is still lacking for the european union emission trading scheme eu ets we therefore present a tractable stochastic equilibrium model reflecting stylized features of the eu ets and analyze the resulting co2 spot price dynamics our main findings are that co2 prices do not have to follow any seasonal patterns discounted prices should possess the martingale property and an adequate co2 price process should exhibit a time and price dependent volatility structure a brief empirical examination regarding market efficiency complements our analysis
