large scale deployment of renewables for electricity generation comparisons of resource assessments suggest that sufficient renewable energy resources are available to allow for large scale deployment of renewable energy technologies economic analysis identifies barriers to the adoption of renewable energy sources resulting from i market structure ii competition in an uneven playing field and iii various non marketplace barriers however even if these barriers are removed the problem of technology lock out remains the key policy response is strategic deployment coupled with increased r d support to accelerate the pace of improvement through market experience this paper suggests significant contributions from various technologies are possible but does not assess their optimal or maximal market share copyright 2005 oxford university press

an analysis of feed in tariff remuneration models implications for renewable energy investment recent experience from around the world suggests that feed in tariffs fits are the most effective policy to encourage the rapid and sustained deployment of renewable energy there are several different ways to structure a fit policy each with its own strengths and weaknesses this paper presents an overview of seven different ways to structure the remuneration of a fit policy divided into two broad categories those in which remuneration is dependent on the electricity price and those that remain independent from it this paper examines the advantages and disadvantages of these different fit models and concludes with an analysis of these design options with a focus on their implications both for investors and for society

assessing the performance of renewable electricity support instruments abstract the performance of feed in tariffs and tradable certificates is assessed on criteria of efficacy efficiency equity and institutional feasibility in the early stage of transition to an energy system based entirely on renewable energy supplies renewable electricity can only thrive if support takes into account the specific technical economic and political problems which result from embedding this electricity in conventional power systems whose technology organizational structure environmental responsibility and general mission differ profoundly from the emerging renewable based system support schemes need to capture the diversity of power supplies the variable nature of some renewable supplies and their different attributes for the purposes of public policy they must take into account the variety of generators including small decentralized generation emerging in a renewable based system and the new relationships between generators and customers renewable energy policies need a clear point of reference because the incumbent power systems are not sustainable they must adapt to the requirements of the renewable ones not the other way round incumbent systems carry the responsibility of paying the transition something that corresponds best with the polluter pays principle

green price indices abstract this paper suggests two theoretically consistent and empirically tractable ways that a cost of living index can be expanded to include the environment and other public goods in addition it presents an empirical illustration of such an index for los angeles california incorporating air quality and other spatially varying public goods using a hedonic model the results indicate that the required information can be recovered and that including public goods can make a substantial difference in the index

the investor specific price of renewable energy project risk a choice experiment with incumbent utilities and institutional investors abstract renewable energy investments in germany have recently soared trebling the output of wind and solar power generation in only ten years while incumbent utilities have lagged behind in terms of investment new entrants have significantly contributed to this growth existing literature has primarily focused on explaining the lethargy of incumbents former investments although there is a growing need to investigate recent investment drivers to secure the necessary power plant capacity at a moderate cost from incumbents and new entrants alike to close this gap a choice experiment involving 1 659 investment choices by 52 european professional investors was conducted in significant contrast to the case with altruistic investors this survey underlines the importance of using financial incentives to attract professional investors given full exposure to electricity price risk incumbent utilities would facilitate projects at a 3 04 risk premium whereas institutional investors demand 6 61 generally incumbent utilities and institutional investors are equally attracted by low risk projects however when risk increases institutional investors are more hesitant to become involved while incumbent utilities confidently navigate these higher risk projects

is the post fossil era necessarily post capitalistic the robustness and capabilities of green capitalism abstract our central target is to show that capitalism is not only much more robust to crises than presumed by its critics but also features promising capabilities with regard to solving the environmental crisis to elaborate this thesis we analyse how far capitalism can survive given the end of fossil energy carriers and may maintain its productivity under the preconditions of a regenerative energy system in a further step we demonstrate that crises may actually provide the prerequisites of the economy s transformation towards sustainability we argue that especially competitive capitalism as analysed by schumpeter offers excellent preconditions for generating environmental innovations however we will also point out the numerous social problems of green infrastructure projects in the last section we assume that markets alone will not suffice to concertedly solve the global environmental crisis here political action is needed that pools societal forces with regard to the ecological challenges hence specifically promoting desirable innovations the usefulness of state measures is to be judged in correlation to the respective specific national political and economic contexts a generalised opposition to capitalistic social orders disregards the complexity of these contexts and is at danger of omitting decisive determinants of crisis management

the impact of systemic factors on the deployment of cooperative projects within renewable electricity production an international comparison while cooperative organizations created with the aim to initiate develop and operate renewable electricity re projects have received attention for their roles in the transition to a sustainable

indices of household welfare and the value of leisure time i introduction a true leisure inclusive welfare index indicates the compensatory change in wage rates goods consumption or nonlabor income required to enable the household to attain some reference period utility given an exogenous change in wage rates and prices although these indices are theoretical constructs for the measurement of individual or household welfare changes empirical analyses of these indices have relied upon aggregate time series data these data provide information on national average changes in wage rates goods consumption and hours worked but do not capture changes in hours worked at the household level due to increased labor market participation while the entry of many new part time workers into the labor market may decrease the national average of hours worked per week there may be a decrease in leisure for many households in addition the aggregate time series approach ignores differences across households in demographic attributes and the occupations and industries in which household members are employed to address these issues two large cross sections of household data the 1972 and 1980 bls consumer expenditure surveys u s bureau of labor statistics 1978 were used to calculate three types of leisure inclusive welfare indices the real wage index goods consumption and nonlabor income indices for each of six household demographic groups households comprising a husband and wife with zero or more dependent non working children were considered as the basic decisionmaking units in this household approach two real wage indices could be constructed that of the husband and that of the wife since the labor services of the two individuals may be valued differently the remainder of the paper is organized as follows in section ii the leisure inclusive welfare indices are developed theoretically the fixed weight bounds on the true indices and the limitations of these indices in the context of a more general but as yet undeveloped intertemporal behavior framework is discussed in section iii the data and empirical results are discussed and analyzed a summary and conclusions follow in section iv along with suggestions for future research

renewable energy growth and the financial performance of electric utilities a panel data study abstract electric utilities are under pressure to increase clean energy production although the adoption of renewable energy can improve the utilities environmental performance a fundamental question is if it also pays in economic terms building on the natural resource based view of the firm we answer this question using two data analysis methods first we carry out a regression analysis of panel data from 66 large electric utilities covering the period 2005 2014 applying both a fixed and random effects estimator subsequently we use the granger causality test to explore possible causality links our results show a negative correlation at the firm level between renewable energy increase and short term as well as long term financial performance more specifically we find that an increase in renewable energy penetration granger causes a reduction of long term performance however the results also show that a firm s carbon intensity moderates the relationship when the focus is on the country level we find that an increase in renewable power penetration is also negatively correlated to long term firm performance which might be explained by the combined effect of low power demand and overcapacity in developed economies we conclude that the concept of organizational ambidexterity may supplement the natural resource based view of the firm for a better understanding of the relationship between an increase in renewable power and a firm s profitability

exploring technology diffusion in emerging markets the role of public policy for wind energy abstract this study challenges the implicit assumption of homogeneity in national institutional contexts made in past studies of renewable energy policy we propose that institutional differences matter by focusing on several technology specific and generic policy factors that can foster technology diffusion through private sector activity more specifically we explore perceptions of early adopters in emerging economy contexts using wind park project developers as an example by applying a parsimonious method for our questionnaire as well as qualitative data we make several contributions methodologically we introduce maximum difference scaling to the energy policy domain empirically we identify several public influences on private investment and assess their relative importance this leads to new insights challenging findings from industrialized economies we identified additional institutional barriers to diffusion hence the requirement of a combination of technology specific and generic policy measures

transforming the energy sector the evolution of technological systems in renewable energy technology this paper analyses the development and diffusion of technologies that utilize renewable energy sources in germany sweden and the netherlands the analysis enlarges the life cycle model of industry evolution to one where the focus is on the formation and evolution of new technological systems particular focus is on explaining success and failures in shifting from a formative phase into one characterized by positive feedbacks a set of challenges is identified for policy makers attempting to influence the process of transforming the energy sector

a coevolutionary framework for analysing a transition to a sustainable low carbon economy this paper proposes a coevolutionary framework for analysing a transition to a sustainable low carbon economy based on the coevolution of ecosystems technologies institutions business strategies and user practices within a multi level micro meso macro perspective this builds on and develops previous coevolutionary analyses of long term technological and industrial change and recent renewed interest within ecological economics on coevolutionary approaches previous work has analysed how the coevolution of technologies and institutions has led to the lock in of current high carbon energy systems and how the coevolution of physical and social technologies and business strategies has brought significant material and welfare benefits to the minority of the world s population living in industrialised countries the coevolutionary framework proposed here may be used to undertake 1 detailed empirical analyses at a micro meso level of the challenges relating to the innovation and adoption of particularly low carbon technologies 2 as a framework for analysing the multi level interaction of social and technological elements within potential transition pathways to a low carbon energy system 3 to assess the implications for economic growth and prosperity of a transition to a low carbon economy and 4 to assist in the development of more formal multi level evolutionary economic models

installed base and compatibility innovation product preannouncements and predation a good is often more valuable to any user the more others use compatible goods the authors show that this effect may inhibit innovation if an installed base exists and transition to a new standard must be gradual early adopters bear a disproportionate share of transient incompatibility costs this can produce excess inertia the installed base however is stranded if the new standard is adopted this may create excess momentum these dynamic effects have strategic implications temporary price cutting can permanently prevent entry and product preannouncements can be critical in innovation these strategic actions have ambiguous welfare effects

measuring the cost of shelter for homeowners theoretical and empirical considerations recent economic developments have aroused substantial interest in the treatment in the consumer price index cpi of the cost of shelter for homeowners from december 1977 when the latest version of the cpi was introduced until december 1980 the all items cpi increased at an average annual rate of 11 6 while the homeownership component increased at an average annual rate of 16 2 relative to all of the other goods and services in the cpi the homeownership component has increased by 17 5 over the same time period if the relative price of homeownership had remained constant the growth rate of the cpi would have been reduced to 10 1 the question which has been raised is whether the rapid relative increase in the homeownership component which has had such an important impact on the cpi truly reflects changes in the cost of shelter this question is not only important but difficult encompassing many subsidiary questions and auxiliary issues the purposes of this paper are threefold 1 to outline briefly a conceptual framework for the cpi which leads to a straightforward specification of what the shelter component of the cpi should measure 2 to evaluate the theoretical properties of alternative procedures designed to approximate this measurement objective and 3 present empirical evidence on the operational difficulties involved in pursuing a new approach to shelter cost measurement two main conclusions are reached first on both theoretical and empirical grounds a rental equivalence approach to measuring shelter costs for owner occupants is preferred second an estimated rental equivalence measure has grown more slowly over at least the past six years than the official cpi homeownership component given the way in which the cpi is used to escalate both private and public expenditures these results demonstrate that the choice of measurement technique has important distributional implications

institutional work and climate change corporate political action in the swedish electricity industry this paper utilises qualitative methods to examine factors that influence corporate political actions cpa linked to climate policy in the swedish electricity industry cpa strategies are examined in connection to two policy instruments the eu emission trading scheme and the swedish electricity certificate scheme these instruments are the main drivers of climate related investments in the sector the study treats cpa as a form of institutional work and examines reasons for companies to seek to maintain disrupt institutions the study finds that cpa is driven primarily by the need to manage external resource dependencies and that where risks are more acute companies are more likely to seek to disrupt regulative institutions however the study also shows that respondents appraisals of policy instruments are based on a convergent set of shared values cognitive institutions that form the basis of cpa and which actors do not seek to disrupt despite resource based risks cpa is thus characterised as a means to transmute cognitively held values and beliefs into regulative institutions the study concludes with implications for policymakers and theory

normal markets market imperfections and energy efficiency abstract the conventional distinction between economic and engineering approaches to energy analysis obscures key methodological issues concerning the measurement of the costs and benefits of policies to promote the adoption of energy efficient technologies the engineering approach is in fact based upon firm economic foundations the principle of lifecycle cost minimization that arises directly from the theory of rational investment thus evidence that so called market barriers impede the adoption of cost effective energy efficient technologies implies the existence of market failures as defined in the context of microeconomic theory problems of imperfect information and bounded rationality on the part of consumers for example may lead real world outcomes to deviate from the dictates of efficient resource allocation a widely held contrary view that the engineering view lacks economic justification is based on the fallacy that markets are normally efficient

who gets the goods a general equilibrium perspective on food aid in mozambique abstract we employ a computable general equilibrium approach to examine the effects of alternative food aid distribution schemes for drought response food aid to mozambique alternative schemes have very distinct impacts on household welfare and prices compared with monetization of food aid by government direct distribution to households by population shares strongly benefits rural households even assuming that government cannot target food aid strictly at drought stricken rural people our results indicate that when improving household welfare is the primary goal of the food aid direct distribution of food aid to households is preferred

sufficient nourishment worldwide via transfer payments abstract the paper illustrates an unconventional approach to providing adequate nourishment worldwide regions with an insufficient calorie supply receive transfer payments in order to increase their food budgets the transfer payments are financed by a flat income tax in oecd countries a general equilibrium model which contains this transfer payment mechanism as well as information about nutrition is applied for the analysis the resulting tax rate is 0 55 of oecd countries income or a required total transfer of 112 billion usd with the money allocated the receiver regions boost their domestic production as well as increasing their food imports this in turn affects agriculture in oecd countries by promoting production

regulating technological change the strategic reactions of utility companies towards subsidy policies in the german spanish and uk electricity markets abstract this paper focuses on how incumbent electric utilities strategically react to subsidy schemes supporting renewable energy technologies in the uk germany and spain firms coordinate the development of their technological capabilities and their political activities to shape their regulatory environment analysing the diffusion of wind power in these countries we show that the different ways in which firms coordinate their technological and political strategies lead to very different market outcomes both for the firms market share and the size of the overall market although incumbents are usually seen as being resistant to change in energy systems we show that spanish utilities proactively drive the diffusion of wind power we speculate about the relation between the ownership structure of the energy system and its inertia with respect to the integration of new technologies we derive novel policy implications that explicitly take into account the strategic actions of incumbent firms shaping the technological and regulatory system

a comparative analysis of the costs of onshore wind energy is there a case for community specific policy support abstract there is growing policy interest in increasing the share of community owned renewable energy generation this study explores why and how the costs of community owned projects differ from commercially owned projects by examining the case of onshore wind in the uk based on cross sectoral literature on the challenges of community ownership cost differences are attributed to six facets of an organisation or project internal processes internal knowledge and skills perceived local legitimacy of the project perceived external legitimacy of the organisation investor motivation and expectations and finally project scale these facets impact not only development costs but also project development times and the probability that projects pass certain critical stages in the development process using survey based and secondary cost data on community and commercial projects in the uk a model is developed to show the overall impact of cost time and risk differences on the value of a hypothetical 500 kw onshore wind project the results show that the main factors accounting for differences are higher pre planning costs and additional risks born by community projects and suggest that policy interventions may be required to place community owned projects on a level playing field with commercial projects

eu renewable energy support policy faith or facts the recent eu commission proposal for promoting the supply of power from renewable energy sources was originally based on a pan european harmonised tradable green certificate tgc scheme we suggest on the basis of a multi disciplinary analysis that a pan eu tgc system is not the way forward for europe it is vital that the commission and the majority of member states avoids implementation of such policy designs put forward by a coalition of vested interests they should instead look at and act upon the available evidence from those countries that have experimented with tgcs e g flanders uk and sweden and design policies that stand a better chance of meeting the criteria of effectiveness efficiency and equity in particular the policies must enable eu to meet the immense innovation industrialisation challenge by inducing the development of a capital goods industry that can eventually diffuse a broad range of technologies that use renewable energy sources only then we can acquire an ability to implement an industrial revolution in the energy system in a way that broadly meets the criteria of effectiveness and dynamic efficiency

the monetization of project and emergency food aid project level efficiency first abstract the level of food aid monetization has increased sharply particularly in africa and especially to cover the transport and non food costs of food aid projects monetization to raise cash is not wrong in principle and increases the efficiency of cash starved projects however the focus on generating counterpart funds has obscured a more important debate about whether and when food is more appropriate than cash at the project level there can be no general predisposition to use either food or cash but guidelines must be applied in each case

the governance of sustainable socio technical transitions a quasi evolutionary model of socio technical transitions is described in which regimes face selection pressures continuously differentiated transition contexts determine the form and direction of regime change in response to these pressures the articulation of pressures and the degree to which responses are coordinated and based on resources available within the regime define the transition context four alternative contexts are described endogenous renewal re orientation of trajectories emergent transformation and purposive transitions agency and power in the governance of regime transformation are analysed power to affect change depends on regime membership the distribution of resources for change and expectations

uncertainties in future energy demand in uk residential heating fossil fuels are the main source of space heating in the uk and therefore climate mitigation implies a systemic change in space heating systems the challenge is difficult because of an inefficient building stock and high penetration of natural gas we present new quantified scenarios for residential energy use in the uk to 2050 with minimal policy intervention the uk will remain locked into a gas based heating system which would conflict with the policy goal of decarbonisation however there is a range of scenarios in which this is avoided a system heavily reliant on heat pumps powered by low carbon electricity is uk policy makers currently preferred alternative we conclude that some shift in this direction is likely to be required but complete reliance on this solution raises a number of problems greater use of energy efficiency and biomass can also play a significant role these options have different risks but a more diversified strategy would be more prudent we conclude that the future of uk residential space heating is very uncertain but meeting low carbon heating goals is better conceptualised as reducing reliance on gas rather than necessarily mass electrification our analysis has implications for any country with high use of fossil fuels in space heating and ambitious decarbonisation goals

the efficiency paradox bureaucratic and organizational barriers to profitable energy saving investments abstract the paradox of why profitable energy saving investments are not undertaken continues to provoke debate the underlying phenomenon might be called the efficiency paradox because it represents a case in which business firms which are often presumed or taken axiomatically to be economically efficient make decisions that do not maximize profits new data from one of the us environmental protection agency s voluntary pollution prevention programs enables this paradox to be explored statistically the data show that both the level and variation in returns to lighting upgrade investments cannot be explained by standard economic models substantial gains in energy efficiency can be achieved without sacrificing profitability both economic and organizational factors account for some of the variation in observed returns to these investments but the results suggest a need for improved and more comprehensive theories of the investment behavior of firms and other organizations

can premium tariffs for micro generation and small scale renewable heat help the fuel poor and if so how case studies of innovative finance for community energy schemes in the uk abstract in the uk the introduction of micro generation feed in tariffs fits and a proposed renewable heat incentive rhi for domestic and small scale schemes have re energised the market for investment in domestic scale renewable energy these incentives may provide financial opportunities for those with capital to spend but for the record numbers with low incomes in fuel poverty these benefits may seem out of reach this paper shows that with appropriate financial intermediaries it is possible for renewable energy incentives to be used to alleviate fuel poverty simple financial analysis demonstrates the theoretical potential of fits to help those in fuel poverty two case studies of renewable energy projects in low income areas investigate how the incentives may be used in practice what barriers exist and what success factors are evident the analysis shows that local energy organisations leos are key if the poor are to access benefits from premium tariff schemes low interest finance mechanisms good information sharing and community involvement are found as key success factors

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

the solow productivity paradox what do computers do to productivity 1 you don t see computers everywhere in a meaningful economic sense computers and information processing equipment are a relatively small share of gdp and of the capital stock 2 you only thinkyou see computers everywhere government hedonic price indexes for computers fall too fast according to this position and therefore measured real computer output growth is also too fast 3 you may not see computers everywhere but in the industrial sectors where you most see them output is poorly measured examples are finance and insurance which are heavy users of information technology and where even the concept of output is poorly specified 4 whether or not you see computers everywhere some of what they do is not counted in economic statistics examples are consumption on the job convenience better user interface and so forth 5 you don t see computers in the productivity statistics yet but wait a bit and you will this is the analogy with the diffusion of electricity the idea that the productivity implications of a new technology are only visible witlh a long lag 6 you see computers everywhere but in the productivity statistics because computers are not as productive as you think here there are many anecdotes such as failed computer system design projects but there are also assertions from computer science that computer and software design has taken a wrong turn 7 there is no paradox some economists are counting innovations and new products on an arithmetic scale when they should count on a logarithmic scale

the dynamic capabilities of firms an introduction an expanded paradigm is needed to explain how competitive advantage is gained and held firms resorting to resource bas ed strategy attempt to accumulate valuable technology assets and employ an aggressive intellectual property stance however winners in the global marketplace have been firms demonstrating timely responsiveness and rapid and flexible product innovation along with the management capability to effectively coordinate and redeploy internal and external competences this source of competitive advantage dynamic capabilities emphasizes two aspects first it refers to the shifting character of the environment second it emphasizes the key role of strategic management in appropriately adapting integrating and re configuring internal and external organizational skills resources and functional competences toward changing environment 3 only recently have researchers begun to focus on the specifics of developing firm specific capabilities and the manner in which competences are renewed to respond to shifts in the business environment the dynamic capabilities approach provides a coherent framework to integrate existing conceptual and empirical knowledge and facilitate prescription this paper argues that the competitive advanis tage of firms stems from dynamic capabilities rooted in high performance routines z operating inside the firm embedded in the firm s processes and conditioned by its history it offers dynamic capabilities as an emerging paradigm of the modern business j firm that draws on multiple disciplines and advances with the help of industry studies in the usa and elsewhere

does food aid have disincentive effects on local production a general equilibrium perspective on food aid in ethiopia this paper examined impacts of food aid on domestic food production employing a computable general equilibrium modelling technique and using data from ethiopia the simulation experiments have shown that food aid has unambiguous disincentive effects on domestic food production the removal of food aid caused a modest increase in food prices but this stimulated food production employment and income generation effects of the latter outweighed the adverse effect of the former consequently the removal of food aid led to improvements in aggregate household welfare contrary to some concerns in the food aid literature that any reduction in food aid would hurt the poor the simulation experiments suggested that actually poor rural households and urban wage earners are the ones who benefit most in absence of food aid but entrepreneurs are more likely to encounter a marginal welfare decline we have distinguished between in kind food aid and cash equivalent transfers in order to isolate the disincentives that in kind transfers would make to domestic production from those that are related to household purchasing power problem the expansionary effect of removing food aid becomes significantly larger when it is accompanied by cash equivalent payments because the latter would provide demand side stimulus to agriculture while the removal of in kind transfers would stimulate supply side with the supply and demand side effects reinforcing each other in our modelling framework the only adverse effect would be a modest deterioration in the external current account because the expansionary effects of food aid would cause imports to rise but exports to fall

governing community energy feed in tariffs and the development of community wind energy schemes in the united kingdom and germany this paper analyses the development of community energy in the uk by comparing it to germany in relation to decentralisation scales and ownership structures particularly of wind energy varying approaches to energy generation at the community scale provide interesting insights into the impact of policy innovation as well as the capacity of national energy frameworks to foster socially innovative engagement practices beyond the purely technological diffusion of innovations by examining interactions between technological and social innovations with the help of a qualitative analysis opportunities for potential generators not traditionally engaged in energy generation to tap into these innovation systems are analysed this paper suggests that greater commitment to diversification beyond the implementation of policy measures such as the feed in tariff is required to provide communities with the capacity to develop new generation practices in terms of scale and ownership the uk in particular is struggling to protect these new generation practices which allow communities to derive benefits facilitated by specific energy policy measures according to their potential it concludes by indicating areas where niche protection might need to be expanded if community energy is to play a greater role in the uk s ambitious transition to a low carbon economy

an econometric analysis of choice of mortgage design in the united kingdom the research seks to better understand the choice of mortgage design by households in the united kingdom family expenditures survey data is used to test the various hypotheses on the determinants of the choice between an endowment and a repayment mortgage a bivariate probit model with sample selection is estimated to detect any likely selectivity bias arising out of tenure choice the theoretical modelling reflects the behaviour of liquidity constrained households comparing comparative periodic mortgage costs and households concerned with the oppurtunity cost of equity in a property actual choices appear to reflect the impact of nominal interest rates income and cash flow considerations there is little direct evidence that the choice of mortgage repayment vehicle is motivated by portfolio design there is some tentative evidence of supply side pressure on endowment mortgage take up

the co evolution of policy mixes and socio technical systems towards a conceptual framework of policy mix feedback in sustainability transitions abstract understanding how policymaking processes can influence the rate and direction of socio technical change towards sustainability is an important yet underexplored research agenda in the field of sustainability transitions some studies have sought to explain how individual policy instruments can influence transitions and the politics surrounding this process we argue that such individual policy instruments can cause wider feedback mechanisms that influence not only their own future development but also other instruments in the same area consequently by extending the scope of analysis to that of a policy mix allows us to account for multiple policy effects on socio technical change and resultant feedback mechanisms influencing the policy processes that underpin further policy mix change this paper takes a first step in this regard by combining policy studies and innovation studies literatures to conceptualise the co evolutionary dynamics of policy mixes and socio technical systems we focus on policy processes to help explain how policy mixes influence socio technical change and how changes in the socio technical system also shape the evolution of the policy mix to do so we draw on insights from the policy feedback literature and propose a novel conceptual framework the framework highlights that policy mixes aiming to foster sustainability transitions need to be designed to create incentives for beneficiaries to mobilise further support while overcoming a number of prevailing challenges which may undermine political support over time in the paper we illustrate the framework using the example of the zero carbon homes policy mix in the uk we conclude with deriving research and policy implications for analysing and designing dynamic policy mixes for sustainability transitions

barriers to energy end use efficiency abstract recent findings indicate that some alternative energy promote equity efficiency and self reliance and are both economical and sustainable the asian development bank therefore initiated a case study to formulate energy strategies which could contribute to the solution of both local and global energy problems the study focuses on technical and economic details of energy end uses in india the conclusions some of which are surprising are supported by data from several studies the study recommends a shift to least cost electricity planning improving the available database for and information availability about energy rationalizing energy pricing and related fiscal policies and achieving energy efficiency by judicious investment in and support of energy forms which will be both sustainable and affordable in the long run

change actors in the u s electric energy system the role of environmental groups in utility adoption and diffusion of wind power we study the contribution of environmental groups to new technology adoption and diffusion by dominant incumbents building on institutional and social movement theory we develop a theoretical framework that sheds light on environmental groups as change actors we theorize that by approaching embedded key constituents with various strategic actions environmental groups affect taken for granted beliefs build legitimacy for renewable energy technologies and convince skeptical constituents to support the new technology we verify our theoretical framework with a case study of wind power development in colorado we find that environmentalists educate constituents on the benefits of the new technology engage in activities leading to regulatory and legislative decisions for wind while also providing direct assistance to the utility as a result utilities are both pressured and encouraged to adopt and diffuse wind power on a large scale this research directs attention to the role of environmental groups as change actors and the legitimating effects of their actions it highlights their part in creating a more favorable institutional environment for new technologies while directly influencing the incumbent s technology choice this paper contributes to an understanding of bottom up actor initiated changes in energy systems taking into account both the systemic technological infrastructure and the institutional context

the costs of mitigating carbon emissions a review of methods and findings from european studies abstract conventional wisdom has it that top down studies of mitigation costs are too pessimistic while bottom up studies are too optimistic in examining mitigation cost studies for western europe this paper finds this interpretation to be flawed the paper expands the analytical framework for interpreting mitigation cost studies evaluates the treatment of no regrets options and other input assumptions in the various studies and includes findings from recent integrated top down bottom up modeling assessments not covered in the ipcc report based on these new elements it is found that mitigation costs tend to be overestimated not only in top down studies but also in bottom up studies given this pervasive bias toward pessimism the body of existing mitigation cost assessments for western europe can be read as follows over the next three to four decades a combination of tax shifts market transformation instruments and policies to reform subsidies and internalize non climatic externalities could cut carbon emissions in western europe by 40 50 relative to the base year at no loss or at a gain in gdp averaged over the medium term and including a phase in period an economically optimal rate of implementing western europe s no regrets potentials is found to be in the neighborhood of 2 per year relative to base year levels

innovation processes in large technical systems market liberalization as a driver for radical change abstract electricity supply is a large technical system which exhibits strong path dependencies and high barriers for radical innovations recent market liberalization however has initiated a fundamental restructuring the paper analyzes how liberalization has altered innovation processes in the field of electricity supply we examine three radical innovations under monopoly conditions and contrast the findings with the results from a survey on the innovation behavior of electric utilities in liberalized markets we argue that the selection environment for innovations has changed in various respects in our sample new options open to innovation activities have emerged at the level of the firm and utility strategies turn out to be more heterogeneous this may be interpreted as an increase in the variety of search processes which may lead to a mid term decrease of path dependencies

what are retail investors risk return preferences towards renewable energy projects a choice experiment in germany citizens own nearly half the renewable energy generation capacity in germany and have been important drivers of the country s energy transition in contrast to citizens important role in financing renewable energies the energy policy and economics literature has traditionally focused on other investors such as incumbent energy firms to close this gap this paper reports on a large scale survey of 1 990 german retail investors conducting a choice experiment with the subset of 1 041 respondents who expressed an interest in investing in community renewable energy projects we present a unique dataset allowing for new insights in risk return expectations of retail investors we find that apart from return on investment respondents are particularly sensitive to the minimum holding period and the issuer of community renewable energy investment offerings a minimum holding period of 10 years implies a risk premium of 2 76 points a subsequent segmentation analysis shows that two groups of potential community renewable energy investors with different risk return expectations can be identified local patriots and yield investors in contrast to professional investors a majority of retail investors use simple decision rules such as calculating payback time or relying on their gut feeling when making investments

not irrational but habitual the importance of behavioural lock in in energy consumption abstract a substantial body of literature has shown that our behaviour is often guided by habits the existence of habits not fully conscious forms of behaviour is important as it contradicts rational choice theory their presence thus calls for the setting of new instruments as they make it unlikely that consumers be capable of exercising control over their energy consumption in reaction to given incentives this is further increased in the evolutionary perspective where the current carbon based socio technical system constrains and shapes consumers choices through structural forces habits being potentially counterintentional they may explain the efficiency paradox in energy as well as the continued increase of energy consumption despite the rising environmental awareness among the population policies aiming at reducing energy consumption should thus specifically address the performance context of habits for instance targeting new residents has proven to be more effective given that their preceding habits have been disturbed the results of our empirical analysis confirm this idea by showing how a change of context makes people more receptive to a proposed measure our analysis of the role played by habits also suggests that individuals do not consider the need to change existing habits as an obstacle even though this is contradicted implicitly in the answers they provided to open questions this unconsciousness is one of the most delicate features of habits and it should thus be accounted for when designing measures given the other characteristics of habits the joint use of feedbacks and commitment strategies appears promising

disordering fantasies of coal and technology carbon capture and storage in australia abstract one of the main ways that continued use of coal is justified and compensated for is through fantasies of technology this paper explores the politics of carbon capture and storage ccs technologies in australia these technologies involve capturing co2 emissions usually to store them safely underground in a process called geo sequestration in australia the idea of clean coal has been heavily promoted and is a major part of co2 emissions reduction plans despite the technological difficulties the lack of large scale working prototypes the lack of coal company investment in such research and the current difficulties in detecting leaks this paper investigates the ways that the politics of clean coal have functioned as psycho social defence mechanisms to prolong coal usage assuage political discomfort and anxiety and increase the systemic disturbance produced by coal power

credible carbon policy the paper sets out the credibility problem in carbon policy provides a number of examples of non credibility in recent energy policy and identifies the costs of failing to address it the time inconsistency of carbon policy arising because of multiple objectives the irreversibility of energy investments and the scope for ex post reneging on ex ante commitments to set policy instruments such as carbon taxes or emission permits at appropriate levels is set in a conceptual framework analogies with monetary policy are drawn and a solution to the time inconsistency problem is proposed through the establishment of an energy carbon agency

does energy policy hurt international competitiveness of firms a comparative study for germany switzerland and austria this paper investigates the impact of energy policies on the export performance of firms there has been a long policy debate on potentially negative impacts of cost increasing energy policies on international competitiveness we use firm level data from three countries with similar industry structure but different energy policies germany switzerland and austria we rely on firm manager assessments on the relevance of energy policy in terms of taxes regulations standards subsidies and demand stimulation for their firm operation and link data on the adoption and development of new energy technologies regression analyses and matching approaches both show very few impacts of energy policy on export performance suggesting that either policy impacts on firms cost are negligible in the period of study 2012 to 2014 or likely negative impacts are balanced by the adoption of new technology

barriers within firms to energy efficient investments abstract many investments in energy efficiency fail to be made despite their apparent profitability internal hurdle rates are often set at levels higher than the cost of capital to the firm reasons for these practices include bounded rationality principal agent problems and moral hazard the policy implication is that government can simultaneously improve overall energy efficiency and increase private sector productivity by providing informational and organizational services that go beyond the traditional regulatory framework

food aid and food markets lessons from mozambique abstract a consensus has emerged on food aid policy acknowledging the importance of short run relief considerations while emphasizing that such policy must be driven by a long run developmental perspective this requires explicit attention to the effects of food aid on food markets yet it has long been clear that short and long run objectives of food aid may conflict this tension stands in high relief in mozambique one of the most food aid dependent countries in the world this paper examines the factors determining the effects of yellow maize food aid on markets for yellow maize and white maize the staple crop in mozambique the paper finds that a food aid has helped fuel the growth of a competitive small scale milling industry and informal marketing system b yellow and white maize are substitutes in consumption and c continued availability of yellow maize food aid at prices well below import parity will depress incentives for producers and traders to invest in the white maize production and marketing system this paper presents recommendations for reforming the monetized food aid program and coordinating it more effectively with emergency aid

distinguished lecture on economics in government data quality and public policy the public policy use of statistical data has increased markedly over the last half century today this country uses statistical series to redistribute income and to fine tune the economy we mandate use of statistical series in a number of our country s laws and we use data to evaluate policy alternatives competing interpretations of statistics on income inflation and unemployment figure prominently in our election campaigns we use statistics to evaluate risk in legislative policy on toxicity and the environment and we use statistics in our governmental efforts to contain the cost of health care under these circumstances the federal government s data system must produce data that are of high enough quality for the demands that are placed upon them but how can we maintain a data system of high quality in an increasingly complex society while at the same time cutting back on government expenditures 1 the quality of a statistical indicator is sometimes elusive and often difficult to define effective measurement requires an underlying conceptual framework and careful identification of the phenomenon to be estimated in the statistical series consider for a moment the task of quality management in a government statistical agency like the u s bureau of labor statistics bls our task is to measure economic and social phenomena which frequently change as does society s view of the 1 for example the appropriations for the bureau of labor statistics have been reduced by nearly 14 5 million over the last 3 years due to deficit reduction legislation these reductions taken proportionately in all bls programs were 9 743 million in fiscal year 1988 2 839 million in fiscal year 1989 and 1 827 million in fiscal year 1990

transition to a post carbon society linking environmental justice and just transition discourses abstract the hunter valley in new south wales australia is a globally significant coal mining and exporting region the hunter economy s strong basis in fossil fuel production and consumption is challenged by civil society campaigns employing environmental justice discourses this paper analyses how two civil society campaigns in the hunter region stop t4 and groundswell have countered the regional hegemony of fossil fuel interests from an environmental justice perspective however the discursive dominance of the jobs versus environment frame hinders efforts to build solidarity amongst local environmental justice goals on the one hand and workers and union aspirations for secure quality jobs on the other long term structural decline of global coal markets adds pressure for economic transition we argue that campaigns to open up possibilities for transition away from fossil fuel dependency to a post carbon society can be strengthened by engaging with the just transition discourses that are typically associated with organised labour doing so can create synergy for social change by aligning community and labour movement interests inclusive social movement partnerships around this synergy must address structural disadvantage that creates social and economic insecurity if communities are to prevail over the fossil fuel sector s hegemony

technology adoption in the presence of network externalities we analyze technology adoption in industries where network externalities are significant the pattern of adoption depends on whether technologies are sponsored a sponsor is an entity that has property rights to the technology and hence is willing to make investments to promote it key findings include the following 1 compatibility tends to be undersupplied by the market but excessive standardization can occur 2 in the absence of sponsors the technology superior today has a strategic advantage and is likely to dominate the market 3 when one of two rival technologies is sponsored that technology has a strategic advantage and may be adopted even if it is inferior 4 when two competing technologies both are sponsored the technology that will be superior tomorrow has a strategic advantage

subsidies for residential solar photovoltaic energy systems in western australia distributional procedural and outcome justice governments seek to increase renewable energy capacity by providing subsidies to householders opting to install residential solar energy photovoltaic systems the funds used to pay for these subsidies are sourced from tax revenue or electricity tariffs paid by all community members including those on a low income this sees a redistribution of funds from all community members to installers of residential solar energy systems this research compared community attitudes towards distributional justice or the fairness of this redistribution of funds with outcome justice associated with the environmental benefits of renewable energy a randomised survey distributed in four metropolitan and two regional communities in western australian resulted in 295 responses a response rate of 22 33 of community members prioritised distributional justice 30 prioritised outcome justice and 37 indicated that they were unsure about their preference however support for renewable energy was found with 80 of respondents supportive of renewable energy subsidies and 68 supportive of renewable energy taxation including in electricity tariffs qualitative comments indicate that in spite of the preoccupation with distributional justice in the residential solar energy literature community members are concerned with procedural justice issues in this case procedural justice can be interpreted as government commitment to existing policy the expanded scope of renewable energy policy and enhanced regulations

the economics of changing course implications of adaptability and inertia for optimal climate policy this paper reviews evidence that energy technologies and systems adapt over time to accommodate external pressures that technical innovation and systemic change in the energy sector is largely induced by need and restrained by potentially large transitional costs a simple integrated model of optimal greenhouse gas abatement over time is presented in which the abatement cost depends on both fixed and transitional elements it is shown that the optimal current response and long run prospects differ radically between the classical economic case in which the cost of a given cutback in emissions is fixed exogenously and the adaptive case in which the response is ultimately adaptive but heavily constrained by inertia ie low fixed but high transitional cost if energy systems are indeed to a large degree adaptive the results demonstrate that as compared with the classical non adaptive case long run stabilization of atmospheric co2 may be optimal even with moderate damages from climate change greater near term abatement efforts are justified and the cost of a given delay in response may be several times higher neglect of the issue of induced technical change and other adaptive responses may invalidate the policy implications drawn from most integrated assessment models developed to date

social impacts of community renewable energy projects findings from a woodfuel case study there is much current interest in the potential of community based renewable energy projects to contribute to transition towards low carbon energy systems as well as displacing fossil fuel consumption by increasing renewable energy generation projects are expected to have a range of social impacts which may result in additional positive sustainability outcomes these include potential to increase acceptance of renewable energy developments awareness of renewable and sustainable energy technologies and issues uptake of low carbon technologies and sustainable pro environmental behaviours to date however there has been little investigation of whether and how these impacts occur this paper presents results from qualitative research investigating the social impacts of a community woodfuel project as experienced by project participants and other local stakeholders findings show projects can raise awareness of renewable energy technologies and increase uptake of renewables overall the case study project successfully changed the local social context for development of woodfuel heating reducing risk for all involved in the future development of this sector particularly in the immediate locality there was some evidence of increased engagement with wider sustainability issues but this was limited to direct participants suggesting local projects need to be supported by wider systemic change to maximise impacts

choice of mortgage instrument liquidity constraints and the demand for housing debt in the uk the research uses microdata to estimate reduced form mortgage demand equations based on truncated regressions dissagregated by choice of mortgage instrument the choice is between a standard annuity mortgage and a balloon type mortgage the endowment the estimates are used to indicate the differential impact of credit market rationing and financial liberalization on households the results indicate significant variations in mortgage demand by choice of mortgage instrument econometric testing demonstrates that the choice between an endowment and a repayment mortgage can be used as an exogenous indicator of liquidity and portfolio positions and different user costs of owner occupation

should the cost of living index provide the conceptual framework for a consumer price index in some countries the cost of living col index serves as the conceptual framework for the cpi but it has been rejected in others this paper reviews issues that have arisen in the statistical agency debate and in the economics literature on the col index including rhetorical matters which have influenced the debate i contend that col theoiy is useful as a decision making framework in estimating components of the cpi and that col index theory provides appropriate guidance for measuring consumer inflation contrary to the view that has been adopted for the european hicp and expressed by an advisory committee for the rpi in several countries the united states netherlands sweden the theory of the cost of living col index provides the conceptual framework for the country s consumer price index cpi see united states department of labor 1997 balk 1994 and dalen 1999 others reject the cost of living index framework an example is the australian bureau of statistics 1997 rejection of the col index is also explicit in an rpi advisory committee recommendation in the united kingdom in still other countries canada being an example official documents for the cpi are ambiguous about the role of the col index statistics canada 1995 the international guideline for consumer price indexes the ilo manual turvey 1989 does not even mention the col index the question has taken on heightened interest recently part of the stimulus comes from the european union s relatively new harmonised indexes of consumer prices hicp for the hicps eurostat has rejected the col

a low carbon industrial revolution insights and challenges from past technological and economic transformations recent efforts to promote a transition to a low carbon economy have been influenced by suggestions that a low carbon transition offers challenges and might yield economic benefits comparable to those of the previous industrial revolutions this paper examines these arguments and the challenges facing a low carbon transition by drawing on recent thinking on the technological economic and institutional factors that enabled and sustained the first british industrial revolution and the role of general purpose technologies in stimulating and sustaining this and subsequent industrial transformation processes that have contributed to significant macroeconomic gains these revolutions involved profound long drawn out changes in economy technology and society and although their energy transitions led to long run economic benefits they took many decades to develop to reap significant long run economic benefits from a low carbon transition sooner rather than later would require systemic efforts and incentives for low carbon innovation and substitution of high carbon technologies we conclude that while achieving a low carbon transition may require societal changes on a scale comparable with those of previous industrial revolutions this transition does not yet resemble previous industrial revolutions a successful low carbon transition would however amount to a different kind of industrial revolution

marketing margins and agricultural technology in mozambique improvements in agricultural productivity and reductions in marketing costs in mozambique are analysed using a computable general equilibrium cge model the model incorporates detailed marketing margins and separates household demand for marketed and home produced goods individual simulations of improved agricultural technology and lower marketing margins yield welfare gains across the economy in addition a combined scenario reveals significant synergy effects as gains exceed the sum of gains from the individual scenarios relative welfare improvements are higher for poor rural households while factor returns increase in roughly equal proportions an attractive feature when assessing the political feasibility of policy initiatives

learning from experience the development of the renewables obligation in england and wales 2002 2010 abstract the uk has enviable renewable resources both onshore wind and offshore wind wave and tidal the offshore valuation group 2010 the government has had policy mechanisms in place since 1990 to encourage these resources to be developed the current mechanism the renewables obligation ro was specifically designed to emphasise competition and therefore to fit in with the uk s overall strategic approach to energy policy however as yet it has not delivered the capacity that it was designed to do and as a result the uk faces a difficult challenge in attempting to meet european wide renewable energy targets for 2020 as well as longer term decarbonisation targets this paper explores some of the major reasons why the ro has performed so poorly to date and considers the prospects for improvement up to 2020 it concludes that the strategic emphasis on competition in the support mechanisms has played a key role in limiting renewables development but that the mechanism has changed significantly since it was introduced however these changes together with proposals for electricity market reform still do not address important elements of risk in comparison with a standard feed in tariff

a bayesian approach to assessing the robustness of hedonic property value studies hedonic price models are widely employed to estimate implicit prices for bundled attributes residential property value studies dominate these applications using a representative cross sectional property value data set we employ bayesian methods to translate a range of priors in covariate selection typical of hedonic property value studies into a range of posterior estimates we also formulate priors regarding measurement error in individual covariates and compute the ranges of resulting posterior means finally we empirically demonstrate that a greater and more systematic use of prior information drawn from one s own data and from other studies can break the collinearity deadlock in this data

the impact of rental properties on the value of single family residences abstract this study examines the effects that single family rental properties in a residential neighborhood have on the value of single family residences in that area the analysis blends real estate valuation concepts with evidence found in the housing maintenance literature and urban succession theory to develop testable hypotheses regarding the property specific proximity related and neighborhood wide impacts of rental properties on property values the data used to test the hypotheses include the tenure status of 23 119 single family residences and 1 162 single family sales regression results support all three hypotheses although numerous studies on the value impacts of other externalities have been published this is the first study to examine the separation of property rights the results of this study provide additional insights into housing maintenance and also have implications for neighborhood zoning regulations

shifting sands the changing case for monetizing project food aid in bangladesh abstract monetization involves local sale of food aid commodities and using the cash to finance other programs to explore the likely consequences of monetization this paper combines a stockpile of recent microeconomic evidence from food and cash for work projects in bangladesh together with a multimarket simulation model results suggest that a switch from food for work s ffw in kind deliveries of wheat to an identical wheat financed cash for work cfw program would unambiguously improve welfare of the poor

recent evolutionary theorizing about economic change this famous passage from marshall s principles of economics it first appeared in the fifth edition which came out in 1907 nicely brings out two issues which are as germane to economics today as they were when marshall wrote the first is the heavy reliance by economists in their formal theorizing on the notion of equilibrium the other is the appeal that biological conceptions3x201d have for many economists particularly when their focus is on economic change

agricultural trade liberalization and low income countries a general equilibrium multimarket approach integrated multimarket general equilibrium models are constructed to analyze the impact on poor cereal importers of rising world prices following oecd trade liberalization archetypes contrast african countries in which cereal imports are not competitive with domestic production africa i to african and asian countries where they are competitive results show rising food import bills and exchange rate depreciation in africa i and the opposite in the other two regions policy implications include promoting agricultural exports from africa i and promoting food crops for import substitution in the other regions food aid needed to shelter the poor during the transition period is calculated

models of technology diffusion abstract the literature on new technology diffusion is vast and it spills over many conventional disciplinary boundaries this paper surveys the literature by focusing on alternative explanations of the dominant stylized fact that the usage of new technologies over time typically follows an s curve the most commonly found model which is used to account for this model is the so called epidemic model which builds on the premise that what limits the speed of usage is the lack of information available about the new technology how to use it and what it does the leading alternate model is often called the probit model which follows from the premise that different firms with different goals and abilities are likely to want to adopt the new technology at different times in this model diffusion occurs as firms of different types gradually adopt it there are actually many ways to generate an s curve and the third class of models which we examine are models of density dependence popularized by population ecologists in these models the twin forces of legitimation and competition help to establish new technologies and then ultimately limit their take up finally we look at models in which the initial choice between different variants of the new technology affect the subsequent diffusion speed of the chosen technology such models often rely on information cascades which drive herd like adoption behaviour when a particular variant is finally selected

housing depreciation and aging bias in the consumer price index i use hedonic regression methods to estimate average rental housing physical depreciation for areas of the united states i estimate downward quality bias of the u s consumer price index cpi caused by rental housing physical depreciation and i develop methods to correct the cpi for such aging bias my physical depreciation estimates imply that recent percentage changes in the u s cpi shelter cost indexes are downward biased by 3 to 4 annually such bias is nonnegligible because recent annual changes in the cpi shelter cost indexes have ranged between 3 5 and 6 8 for various regions my results also imply that rent controlled housing has depreciated faster than other rental housing

current challenges of germany s energy transition project and competing strategies of challengers and incumbents the case of direct marketing of electricity from renewable energy sources electricity generated by renewable energies res e already accounts for 25 of germany s electricity supply this has led to recent discussions for a better market integration of res e the paper examines how competing actors and their ideas on market integration developed new services for direct marketing according to their respective origins and tried to shape the regulatory framework the paper analyses this process and explains the current shape of the field of direct marketing medium sized structured actors who favoured res e integration via the conventional wholesale power markets and who formed early close coalitions with res e power producers at the same time have been most successful in terms of market shares moreover they have been very successful for different reasons in building up coalitions with governance units and influencing the field rules and routines based on those findings the paper will conclude with some policy advices for the future adjustment of the current regulative frameworks as long as there is no evidence of how res e can be integrated most effectively and efficiently policies should maintain a competition between different direct marketing strategies to find out which strategies serve the best in terms of achieving a successful energy transition

environmental food taxes and inequalities simulation of a meat tax in sweden abstract this paper investigates the distributional effect of an environmental tax on meat in sweden if such a tax was to be introduced welfare effects are measured as compensation variation cv for multiple price changes where hicksian cross price elasticities household expenditures and price changes are included in the calculations results show that taxes on meat are almost neutral over households when expenditures on meat are used as welfare indicators and regressive if income is used this can be explained by the households similar shares of total expenditures on meat the households with the smallest income levels need to be compensated with 904 sek per person and year equivalent to euro 86 6 per year in the year 2009 exchange rate to feel that utility is not lowered if taxes on meat are introduced and the households with the highest income levels need to be compensated with 1141 sek euro 109 3 per person and year for the year 2009 these compensations correspond to 0 74 and 0 78 of total expenditures for the low and high income group respectively when instead comparing the compensation with income levels the effects correspond to 0 99 for the households with the smallest income levels and to 0 51 for the households with the largest income

project food aid and equitable growth income transfer efficiency first abstract this paper discusses the income transfer properties of food aid in order to shed light on the inputs necessary to ensure a contribution to equitable growth particularly with reference to the alleviation of poverty and malnutrition the author defines the concepts of income transfer efficiency and nutrition efficiency and shows that food aid which is income transfer efficient is usually also nutrition efficient some empirical evidence of the income transfer efficiency of different commodities supplied to various countries is reviewed and policy implications for the selection of food aid commodities and projects are discussed the author concludes with some working propositions designed to stimulate further debate on the selection and administration of food aid projects

the co evolutionary relationship between energy service companies and the uk energy system implications for a low carbon transition abstract the energy service company esco business model is designed to reward businesses by satisfying consumers energy needs at less cost and with fewer carbon emissions via energy demand management and or sustainable supply measures in contrast the revenue of the incumbent energy utility company euco model is coupled with the sale of units of energy which are predominantly sourced from fossil fuels the latter is currently dominant in the uk this paper addresses two questions first why has the esco model traditionally been confined to niche applications second what role is the esco model likely to play in the transition to a low carbon uk energy system to answer these the paper examines the core characteristics of the esco model relative to the euco model the paper then examines how escos have co evolved with the various dimensions of the energy system i e ecosystems institutions user practices technologies and business models to provide insight into how escos might help to shape the future uk energy system we suggest that institutional and technological changes within the uk energy system could result in a more favourable selection environment for escos consequently enabling the esco model to proliferate at the expense of the euco model

housing price functions and ownership capitalization rates abstract in this paper we examine the problem of consistently estimating capitalization rates and hedonic housing prices we specify a hedonic pricing model for housing that combines owner occupied and rental unit samples in a manner yielding hedonic prices not subject to selection bias and capitalization rates which vary with the age and family income of the residents we use the 1982 annual housing survey ahs for metropolitan philadelphia to obtain parameter estimates for this model our findings indicate that selectivity bias is present in price functions utilizing only owner occupied or rental unit samples our results further indicate that the mean annual capitalization rate for owner occupied units is approximately 10 however the capitalization rate is non monotonically related to both age of the head and family income

uk innovation systems for new and renewable energy technologies drivers barriers and systems failures abstract a better understanding of the systemic processes by which innovation occurs is useful both conceptually and to inform policy making in support of innovation in more sustainable technologies this paper analyses current innovation systems in the uk for a range of new and renewable energy technologies and generates policy recommendations for improving the effectiveness of these innovation systems although incentives are in place in the uk to encourage innovation in these technologies system failures or gaps are identified in moving technologies along the innovation chain preventing their successful commercialisation sustained investment will be needed for these technologies to achieve their potential it is argued that a stable and consistent policy framework is required to help create the conditions for this in particular such a framework should be aimed at improving risk reward ratios for demonstration and pre commercial stage technologies this would enhance positive expectations stimulate learning effects leading to cost reductions and increase the likelihood of successful commercialisation
