landlords versus tenants information asymmetry and mismatched preferences for home energy efficiency abstract new zealand homes are poorly insulated by international standards there are government subsidies available for people to improve the energy efficiency of their homes but uptake has been relatively low among owners of rental properties this paper presents the results of a choice experiment used to investigate the preferences of home owners and tenants for insulation and heating upgrades the responses indicate that landlords may underestimate how cold their rental properties are in winter considering the level of discomfort reported by tenants median willingness to pay wtp for improved insulation by landlords is only 50 70 of owner occupier values landlords are willing to pay more for a heating appliance than any other retrofit option in contrast tenants have a low wtp for the heating appliance and would prefer under floor insulation tenants express a willingness to pay higher rent in exchange for improved energy efficiency at a rate that would appear to make such upgrades economic for the landlord information asymmetry and lack of appropriate market signals may be a large part of the reason why many landlords are not willing to pay market prices for energy efficiency upgrades

asset transformation and the challenges to servitize a utility business model abstract the traditional energy utility business model is under pressure and energy services are expected to play an important role for the energy transition experts and scholars argue that utilities need to innovate their business models and transform from commodity suppliers to service providers the transition from a product oriented capital intensive business model based on tangible assets towards a service oriented expense intensive business model based on intangible assets may present great managerial and organizational challenges little research exists about such transitions for capital intensive commodity providers and particularly energy utilities where the challenges to servitize are expected to be greatest this qualitative paper explores the barriers to servitization within selected swiss and german utility companies through a series of interviews with utility managers one of them is asset transformation the shift from tangible to intangible assets as major input factor for the value proposition which is proposed as a driver for the complexity of business model transitions managers need to carefully manage those challenges and find ways to operate both new service and established utility business models aside policy makers can support the transition of utilities through more favorable regulatory frameworks for energy services and by supporting the exchange of knowledge in the industry

analysing the determinants of environmental technology investments a panel data study of spanish industrial sectors abstract the aim of this paper is to empirically assess the determinants of environmental technology investments in the spanish industrial sectors with the help of panel data econometric techniques the paper confirms the relevance of the stringency of environmental regulation to explain overall investment patterns in environmental technologies these investments are also positively related to human and physical capital intensity and r d intensity and negatively related to the export intensity of sectors furthermore the study shows that the determinants for investments are likely to differ between environmental technology types i e end of pipe versus cleaner technologies

influences on energy supply infrastructure a comparison of different theoretical perspectives changes to the energy supply infrastructure are a vital component of climate change mitigation strategies but what exactly underlies changes to energy supply infrastructure this paper through exploration and critical analysis of relevant literature explores the various underpinning influences on energy infrastructure supply using a comparison of different theoretical perspectives these influences were explored with specific emphasis on techno economics social psychology socio technical transitions social practices and institutional dimensions to energy supply the aim was to have a better understanding of the direct and indirect role of politics and the political system in influencing energy supply infrastructure decisions through the various theoretical lenses the study revealed that techno economics uses financial instruments and market information as intervention tools its effectiveness is measured by social welfare and cost effectiveness social psychology uses a combination of information incentives and innovative informative instruments as its intervention tools its effectiveness is measured by behavioural change institutions use regulatory instruments as its intervention tool its effectiveness is measured by regulatory compliance social practices look at change in broader social systems its effectiveness is measured by social change socio technical transitions focus on determining social movements and social innovations its effectiveness is measured by legitimacy and social learning

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

values in the smart grid the co evolving political economy of smart distribution investing in smart grid infrastructure is a key enabler for the transition to low carbon energy systems recent work has characterised the costs and benefits of individual smart investments the political economy of the uk electricity system however has co evolved such that there is a mismatch between where benefits accrue and where costs are incurred leading to a problem of value capture and redeployment further some benefits of smart grids are less easy to price directly and can be classified as public goods such as energy security and decarbonisation this paper builds on systemic treatments of energy system transitions to characterise the co evolution of value capture and structural incentives in the electricity distribution system drawing on semi structured interviews and focus groups undertaken with smart grid stakeholders in the uk this leads to an identification of municipal scale values that may be important for business models for the delivery of smart infrastructure municipalities may thus pursue specific economic opportunities through smart grid investment this supports recent practical interest in an expanded role for municipalities as partners and investors in smart grid infrastructures 2014 the authors published by elsevier ltd this is an open access article under the cc by license

exchange rate overshooting the trade balance and rational expectations abstract this paper presents a model of exchange rate determination characterized by imperfect asset substitutability between domestic and foreign bonds sticky goods market prices and rational expectations the model is used to analyze the response of the exchange rate to a step change in relative money supplies the assumption of imperfect asset substitutability permits introduction into the analysis of trade flows which respond to relative price changes these flows create non monotonic exchange rate adjustments to long run equilibrium these non monotonic adjustments are consistent with rationality and may lead to short run undershooting or overshooting

assessing the consumers willingness to adopt a prepayment metering system in nigeria abstract despite the rising popularity in the adoption and usage of prepayment meters little is still known about the drivers of its adoption we examine the willingness to adopt prepayment metering ppm for a sample of nigerian households that were not prepayment users double hurdle models were estimated to account for households decisions concerning billing system switching behaviour and households willingness to pay wtp the estimated results revealed that decisions to adopt a prepayment meter are significantly affected by current electricity spending current billing method and the split incentive problem whereas current electricity spending significantly increased the tendency to adopt ppm the split incentive problem reduced the probability of adoption although unmetered consumers were more likely to express a willingness to adopt a ppm system than post paid customers they did not intend to pay a significantly higher amount to obtain the prepayment service income did not play a significant role in decision making concerning ppm adoption and the corresponding wtp amount these results cast doubt on the validity of the widely held belief that low income may be responsible for ppm adoption reflecting the widespread usage of ppm by low income households

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

history friendly models of industry evolution the computer industry the model presented in this paper is the first of a new generation of evolutionary economic models history friendly models history friendly models are formal models that aim to capture in stylized form qualitative and appreciative theories about the mechanisms and factors affecting industry evolution technological advance and institutional change put forth by empirical scholars of industrial economics technological change business organization and strategy and other social scientists in this paper we have analyzed the long term evolution of the computer industry in particular we have examined the emergence of a dominant firm in mainframes the introduction of a major innovation microprocessor the opening up of a new market segment personal computers ad the competition there between newcomers and diversified old established firms we have taken a body of verbal appreciative theorizing developed a formal representation of that theory and found that the formal version of that theory is consistent and capable of generating the stylized facts the appreciative theory purports to explain going through this analytic exercise has significantly sharpened our theoretical understanding of the key factors behind salient aspects of the evolution of the computer industry copyright 1999 by oxford university press

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

ecological macroeconomic models assessing current developments our society faces a dilemma while continued economic growth is ecologically unsustainable low or negative rates of economic growth are accompanied by adverse social impacts hence there is a need for macroeconomic tools that can help identify socially sustainable post growth pathways the emerging field of ecological macroeconomics aims to address this need and features a number of new macroeconomic modelling approaches this article provides 1 a review of modelling developments in ecological macroeconomics based on the literature and interviews with researchers and 2 an analysis of how the different models incorporate policy themes from the post growth literature twenty two ecological macroeconomic models were analysed and compared to eight policy themes it was found that environmental interactions and the monetary system were treated most comprehensively themes of income inequality work patterns indicators of well being and disaggregated production were addressed with less detail while alternative business models and cross scale interactions were hardly addressed overall the combination of input output analysis with stock flow consistent modelling was identified as a promising avenue for developing macroeconomic models for a post growth economy however due to the wide interpretation of what the economy entails future research will benefit from employing a range of approaches

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

energy investment risk assessment for nations along china s belt road initiative abstract overseas energy investment as an effective way of securing energy supply is being favored by the world s leading energy consuming countries however energy investment has the potential high risk on multiple forms including political and regulatory risk currency liquidity and refinancing risk as well as resource risk and so on to effectively evaluate overseas energy investment risk this study proposed a new indicator system from six dimensions furthermore a fuzzy integrated evaluation model based on the entropy weight was constructed to rate the energy investment risk for 50 nations along china s belt road initiative the findings indicate that resource potential and chinese factors have become the main determinant of energy investment risk while environmental constraints and political risk should also be considered for investing decisions in conclusion saudi arabia united arab emirates pakistan kazakhstan and russia are the most ideal choices for china s energy investment balancing resource potential and investment environment

the role of intermediaries in low carbon transitions empowering innovations to unlock district heating in the uk abstract the literature on socio technical transitions considers how technological innovations can be established within the context of an incumbent regime that is often resistant or inflexible to change strategic niche management is an approach to catalysing a transition to a new regime using protected niche spaces to enable development and experimentation with an innovation intermediary actors play an important role in establishing these niches as they facilitate knowledge sharing and build the wider networks and systems needed to support an innovation the influence of intermediaries within socio technical transitions and strategic niche management is still an under researched area in this paper we use a decision theatre research process to collect empirical evidence from a range of local stakeholders involved in establishing new district heating projects in the united kingdom uk this method carried out in a group workshop format enables understanding of the interactions between stakeholders throughout the stages of the district heating development process the study suggests that intermediaries can play a role in supporting niche empowering processes the existing institutional framework surrounding intermediary actors and the geographical scale at which they work within that framework are shown to be influential on actors agency to choose their approach to empowering an innovation the work highlights the potential for intermediaries to support the restructuring of this institutional framework to enable more radical stretch and transform empowering activities

scaling up local energy infrastructure an agent based model of the emergence of district heating networks abstract the potential contribution of local energy infrastructure such as heat networks to the transition to a low carbon economy is increasingly recognised in international national and municipal policy creating the policy environment to foster the scaling up of local energy infrastructure is however still challenging despite national policy action and local authority interest the growth of heat networks in uk cities remains slow techno economic energy system models commonly used to inform policy are not designed to address institutional and governance barriers we present an agent based model of heat network development in uk cities in which policy interventions aimed at the institutional and governance barriers faced by diverse actors can be explored three types of project instigators are included municipal commercial and community which have distinct decision heuristics and capabilities and follow a multi stage development process scenarios of policy interventions developed in a companion modelling approach indicate that the effect of interventions differs between actors depending on their capabilities successful interventions account for the specific motivations and capabilities of different actors provide a portfolio of support along the development process and recognise the important strategic role of local authorities in supporting low carbon energy infrastructure

a policy approach to the environmental impacts of technological lock in abstract the broadening spectrum of environmental problems the uncertainty regarding their scale and duration and their possible irreversibility in the context of the growing social preference for environmental quality make it necessary to undertake an ex ante approach to the link between productive activity and environmental quality this link lies in technology and the right approach is to understand how the process of technological change can lead towards sustainability the added value of evolutionary economics in the context of environmental policy resides mainly in the fact that it warns that certain inferior environmental technologies may be locked in to the economic system the results of our model show that it would be advisable to undertake policies expressly aimed at the process of sustainable technological change applying an ex ante precautionary approach in a way that is complementary to the conventional equilibrium oriented environmental policies the nature of these policies and how they might be implemented are questions we will address from this novel approach to the concept of sustainable development in short the main objectives of this paper are to understand more fully the dynamics of the process of technological change its role in sustainable development and to assess the implications of this dynamic approach to techno environmental policy to achieve these goals we have developed an agent based model abm using distributed artificial intelligence dai concepts drawn from the general methodology of social simulation

empowered examining self disconnection in a postal survey of electricity prepayment meter consumers in new zealand abstract prepayment metering is an electricity payment method often used by low income consumers fuel poverty is an important public health problem in new zealand and is likely to be a particular problem for those using prepayment metering this paper details a nationwide postal survey of consumers undertaken with the support of three major electricity retailers which investigated the advantages and disadvantages of using prepayment metering from a consumer perspective the study surveyed a total pool of 359 randomly selected consumers across the three companies a response rate of 48 the study found that while almost all respondents felt the benefits of using prepayment outweighed the risks of running out of credit or self disconnection 53 of respondents experienced self disconnection in the past year of concern over a third of respondents experiencing self disconnection were without electricity for more than 12 h the frequency of self disconnection was also high with 17 of those disconnecting reporting six or more events in the past year government intervention could reduce the risks and disadvantages involved with using prepayment metering which could then support initiatives aimed at reducing fuel poverty

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

speculative intensity and spot and futures price variability this paper develops a simultaneous stochastic rational expectations model of futures and spot price determination using the model we find that increases in what we term speculative intensity increase spot price variability arising from storage cost shocks but decrease spot price variability arising from demand shocks in contrast increases in speculative intensity unambiguously decrease futures price variability regardless of the underlying source of disturbances we are able to develop these comparative static results because the model has a unique equilibrium

does ecological economics have a future contradiction and reinvention in the age of climate change abstract this paper addresses the role of neoclassical methodologies in ecological economics and the contradictions these methodologies pose to the field s critical founding principles we first consider robert costanza s treatment of nicholas stern s global deal and then survey climate change related articles published in this journal over the past five years this survey reveals how mainstream neoclassical methodologies dominate discourse and do so by marginalizing more critical political economy analyses this situation imperils the field s founding vision of a no growth steady state it also fails to address the related growth dynamics of capitalism without such a critical treatment the field s formal embrace of methodological pluralism actually entails an ideological empiricism that renders ecological economics theoretically incoherent this situation undermines the field s historical promise as an alternative economic paradigm ecological economics now faces a problematic future its survival in a form faithful to its founding vision will require an explicit choice to address its internal contradictions and reinvent itself in ways relevant to our contemporary context without such a choice ecological economics will likely succumb to an implicit acceptance of the hegemony of mainstream economic methodologies and their pro growth imperatives

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 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

the development of policy instruments in supporting low carbon governance in china abstract this paper examines the development of policy instruments that support the low carbon governance in china the instruments are analysed in five aspects in relation to the key policies in low carbon governance in china including energy conservation developing new energy reforestry developing circular economy and industry restructuring each aspect is discussed in three instrument groups which are 1 law and regulations 2 industry standard and 3 finance and taxation this research suggests that law enforcement for the new established laws should be further strengthened and stricter supervision systems should be in place to safeguard effective implementation of low carbon policies measures and standards especially for those energy condensed sectors more rigorous industry standards regarding energy efficiency should be considered to help eliminate outdated equipments in industries and promote the introduction of more climate friendly technologies the industrial standards should be given strong legal support in accountability in order to enforce their complete application once in operation new policies and instruments need to be introduced in order to reduce carbon print by landfill the backward law and industrial standards in china should be upgraded more regularly therefore to support the low carbon development strategy

increasing returns path dependence and the study of politics it is increasingly common for social scientists to describe political processes as path dependent the concept however is often employed without careful elaboration this article conceptualizes path dependence as a social process grounded in a dynamic of increasing returns reviewing recent literature in economics and suggesting extensions to the world of politics the article demonstrates that increasing returns processes are likely to be prevalent and that good analytical foundations exist for exploring their causes and consequences the investigation of increasing returns can provide a more rigorous framework for developing some of the key claims of recent scholarship in historical institutionalism specific patterns of timing and sequence matter a wide range of social outcomes may be possible large consequences may result from relatively small or contingent events particular courses of action once introduced can be almost impossible to reverse and consequently political development is punctuated by critical moments or junctures that shape the basic contours of social life

globalizing carbon lock in this paper extends the arguments surrounding carbon lock in elaborated in unruh energy policy 28 2000 817 30 2002 317 to countries currently undergoing industrialization it argues that for numerous reasons industrializing countries are unlikely to leapfrog carbon intensive energy development on the contrary carbon lock in may be globalizing and could further constrain climate change mitigation options it is then argued that many policy recommendations ignore carbon lock in possibly limiting their potential for successful implementation the paper then discusses four policy approaches that appear to have advantages given lock in conditions it is recognized however that relative ease of implementation does not necessarily equate with superiority instead it is merely a path dependent outcome of past development decisions pursuing policies on the basis of relative implementation ease may help address the issue of climate change but could also result in sub optimal outcomes along other dimensions of sustainable development

the effect of excessively elastic expectations on exchange rate volatility in the dornbusch overshooting model abstract bilson has described the empirical finding that the forward exchange rate overestimates the speed of return to equilibrium as a finding of excessive speculation and has drawn implications for the volatility of the exchange rate the present paper pursues this tack within the sticky price monetary model made famous by dornbusch it is shown theoretically that if the market overestimates the speed of adjustment the degree of overshooting is reduced in this sense excessive speculation leads to reduced volatility

innovation and policy for bioenergy in the uk a co evolutionary perspective de laurentis c innovation and policy for bioenergy in the uk a co evolutionary perspective regional studies this paper analyses the role of niche innovation and regime interaction in the field of renewable energy in the uk adopting a co evolutionary approach and a dynamic multilevel perspective on system innovation it investigates niches development in the uk in the field of bioenergy and its interaction with the current energy regime contributing to the debate about spatial scales at which sustainability transitions can be conceptualized the paper utilizes the case of niche development in the region of wales to provide supporting evidence of the importance of context specific social and political relations that may foster or hinder regime transformation

chinese investment in the eu renewable energy sector motives synergies and policy implications abstract this paper addresses three questions how have trade and investment in wind and solar sectors evolved between the eu and china in recent years is there a link between rising trade conflicts and trade and investment trends and what wider motivations and synergies can be identified in chinese investments in the eu s re sector to address these questions we analyze trade and investment data as well as qualitative data including information from media and company reports large increases in trade and investment were followed by rapid falls since 2012 13 trade tensions have not led to increases in investment rather the inverse we find that chinese investment in these two sectors is very concentrated in germany the key motivation for investment is market seeking although r d is also important especially for wind most investments are greenfield a preference that has persisted over time our qualitative analysis of several key acquisitions indicates that technology integration and the consolidation of capacities across the supply chain were key motivations in most of the cases studied we conclude with some policy orientations

investments and cleaner energy production a portfolio analysis in the italian electricity market abstract the recent climate change global warming environmental disasters and the economic crisis are only the first signs of the failure of an economic system that for too long shows an uncontrolled utilization of the planet wealth the italian electricity market which is strongly dependent on hydrocarbons only in recent years has seen a first attempt to change towards renewable resources for electricity production aimed at self consumption and for feeding into the grid this paper presents an economic analysis whose purpose is to evaluate the profitability of investments in renewable technologies for the production of electricity each renewable source has its own profitability dependent on a number of factors and subject to market fluctuations cost and frequent changes in the incentive policies applying portfolio theory is possible to select the right mix of renewable energy sources and simulate its evolution moreover the presented analysis can be useful for energy planners to select future green scenarios finalized to the reduction of emissions and energy imports through the increasing use of renewable energy

objective and subjective measures of fuel poverty as energy prices continue to rise to reflect the real cost of carbon the numbers of households in fuel poverty is increasing rapidly this paper uses a unique data set to explore one alternative measure of fuel poverty based on whether consumers feel able to afford their energy similar to one introduced by the government a few years ago we explore the links between an expenditure based and our subjective measure of fuel poverty and compare these differences with those between official measures amongst low income households 28 spent more than a tenth of their income on energy in the home and so would be likely to qualify as fuel poor under the most usual definition but only 16 felt unable to afford sufficient energy to keep their homes warm amongst this group who felt they had difficulty in affording sufficient energy less than half were expenditure fuel poor the paper argues that reintroduction of a self reported measure by the government would be a valuable aid to policy development

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

econ 101 in need of a sustainability transition abstract ecological economics was one of the first of a number of scientific communities to develop transdisciplinary understandings of the sustainability challenges faced by society as a field with economics in its name ecological economics differs from the other communities and should face the particular task of contributing to the development of a new economics for economics to promote sustainability transitions it is not enough to call for more pluralism a new basic structure of economic knowledge should be developed in order to provide the foundation for a sustainability transition to econ 101 this paper argues that the performativity of economics needs to change and proposes a way of structuring econ 101

escaping carbon lock in this article explores the climate policy implications of the arguments made in understanding carbon lock in unruh 2000 which posited that industrial countries have become locked into fossil fuel based energy systems through path dependent processes driven by increasing returns to scale carbon lock in arises through technological organizational social and institutional co evolution culminating in what was termed as techno institutional complex tic in order to resolve the climate problem an escape from the lock in condition is required however due to the self referential nature of tic escape conditions are unlikely to be generated internally and it is argued here that exogenous forces are probably required

institutional reform and technological practice the case of electricity this article proposes a framework for categorizing possible interrelations between technological and institutional change and applies this framework to the case of the restructuring of the electricity sector it is argued that there is a need for coherence between institutions and technological practice so as to safeguard the satisfactory functioning of electricity infrastructure the identification of possible incoherences between institutions and technological practice allows for a better understanding of the potential drivers for change and the evolutionary processes of which they may be part this article attempts to elaborate the nature of this co evolution in somewhat more detail using specific levels of analysis that are exemplified in a four level model in the case of the restructuring of the electricity sector the institutional framework has changed from a public utility oriented towards a market oriented system however the technological practice remained unchanged a system oriented approach that relies on centralized planning control and operation this discrepancy between institutions and technological practice leads to significant frictions in the functioning of the electricity sector but it also offers opportunities for innovation in order to make liberalization a success it might be necessary to stimulate certain technical developments i e distributed generation and intelligent networks

making the connection the relationship between fuel poverty electricity disconnection and prepayment metering abstract fuel poverty or inability to afford adequate heating for a reasonable outlay of expenditure is a significant and under researched problem in new zealand the connection between fuel poverty and electricity disconnection or self disconnection is analysed for four cities using prepayment metering to pay for electricity a price comparison analysis on a government sponsored website showed that prepayment metering was more expensive than other payment options this website analysis was supplemented by qualitative data from older people with chronic respiratory disease expressing their views about electricity disconnection and prepayment metering we show that prepayment metering for electricity is more expensive than other payment methods in new zealand and that older people s insights provide valuable context to these issues under the present payment schedule the use of prepayment metering to pay for electricity is not a suitable policy instrument to address fuel poverty which remains problematic the deregulated electricity market continues to lead to increases in the real price of residential electricity and in the number of people in fuel poverty we offer policy suggestions for reducing fuel poverty in new zealand

spot and forward rates in a stochastic model of the foreign exchange market abstract in this paper we develop a simultaneous stochastic model of spot and forward exchange rate determination under rational expectations for spot rates we find that increases in speculative responsiveness dampen the effects of trade balance shocks but exacerbate effects of interest rate shocks for forward rates though increases in speculative responsiveness dampen the effects of both trade balance and interest rate shocks the bias of the forward forecast error decreases as specualtive responsiveness increases but the expected squared error may increase

evolving theories of sustainability and firms history future directions and implications for renewable energy research abstract sustainability has become a critical perspective in managing firms via a holistic approach by considering economic environmental and social dimensions of firms with the rising significance of sustainable development the theories of sustainability in firms have evolved during the past six decades this article offers a critical review of the evolving theories linking sustainability to firms and discusses their implications for future renewable energy research the relationships among different theories are critically analysed and the directions for future research are discussed the paper shows that the main theories linking sustainability to firms in a chronological order are 1 corporate social responsibility 2 stakeholder theory 3 corporate sustainability and 4 green economics currently various innovative approaches and new theories emerged such as co evolution theory and multi level perspective reflecting three directions of theory development namely 1 shifting from what to how 2 growing use of interdisciplinary approach and 3 towards broader systems renewable energy studies associated with firms and future research opportunities in this area are also critically analysed the comprehensive review offered in this paper provides a useful reference for policy makers corporate managers and researchers interested in corporate sustainability and renewable energy related studies

coping with low incomes and cold homes abstract this paper presents findings from a study of low income households in great britain which explored households strategies for coping both with limited financial resources in the winter months when demand for domestic energy increases and in some cases with cold homes the study combined a national survey of 699 households with an income below 60 per cent of national median income with in depth interviews with a subsample of 50 households the primary strategy adopted by low income households to cope with financial constraint was to reduce spending including spending on essentials such as food and fuel and thereby keep up with core financial commitments while spending on food was usually reduced by cutting the range and quality of food purchased spending on energy was usually reduced by cutting consumption sixty three per cent of low income households had cut their energy consumption in the previous winter and 47 per cent had experienced cold homes improvements to the thermal performance of homes reduced but did not eliminate the risk of going cold as any heating cost could be a burden to households on the lowest incomes householders attitudes were central to their coping strategies with most expressing a determination to get by come what may

institutional ecological economics abstract new institutional economics and its forerunners have we argue made important contributions to the evolving agenda of ecological economics the conceptualisation of environmental problems as instances of interdependence and the acknowledgement of positive transaction costs are key insights into the nature of environmental problems we also discuss how plurality of behavioural motivations and limited cognitive capacity have important implications for environmental decision making and its analysis we show how evolutionary and collective action theories offer complementary takes on the choice and change of environmental governance institutions and how the concept of social capital can enrich analyses of environmental governance we conclude that an emerging institutional ecological economics has the greatest relative advantage in analysing the design implementation and effectiveness of environmental governance solutions

addressing self disconnection among prepayment energy consumers a behavioural approach abstract this paper explores links between self control in decision making and self disconnection by households using energy prepayment meters self disconnection happens when households exhaust all available credit in their meter and are left without a supply of energy because they have been unable to top up this has serious consequences for the well being of households and also increases firms costs we explore behavioural characteristics associated with self disconnection and present saving plans to help households minimise self disconnection we show that in our sample stated self disconnection is positively associated with lower levels of goal achievement we also show that households which have already experienced self disconnection are more likely to accept an energy savings plan it is relevant and promising that these households tend to select saving plans most likely to minimise their likelihood of self disconnection our findings give some useful insights for energy policy making both for policy makers interested in alleviating energy poverty and for energy utilities keen to limit self disconnection

uncertainty of climate policies and implications for economics and finance an evolutionary economics approach the assessment of the socio economic and financial impacts of climate change represents a main source of uncertainty for policy makers and investors however traditional climate economics and financial risk models are not properly equipped to consider the characteristics of climate risks and the opportunities from climate alignment being constrained by equilibrium conditions and linearity of impacts as well as by representative agents and intertemporal optimization given the closing window of opportunity to achieve the 2 c target there is an urgent need for a new wave of models able to embrace uncertainty and complexity deriving not only from climate impacts on socio economic systems but also from their reaction in this regard approaches rooted on evolutionary economics and complexity science could provide complementary insights to traditional climate economics models this special issue contributes to fill in this knowledge gap by collecting nine papers applying evolutionary and complex systems approaches and agent based and network models to climate change economics presented at the special session of the research area environment economics interactions of the european association of evolutionary political economy eaepe s conference 2016 by introducing conceptual and methodological innovations in climate economics and finance the nine articles analyse the conditions for effective climate policies and financial instruments to align countries to the global climate targets compared to the costs of inaction this information is crucial to support decision makers in the analysis of climate finance policies and instruments to foster the transition to a sustainable and inclusive low carbon economy

integrating finance into the multi level perspective technology niche finance regime interactions and financial policy interventions abstract any major socio technical transition requires a fundamental re direction of financial capital from incumbent to new technologies and practices while the transitions literature conceptually covers financial markets the role of finance is marginalized and has scarcely been analysed empirically to address this gap here we build on the multi level perspective mlp which considers financial markets as part of the existing regime we argue that the role of finance is highly relevant for the niche regime interaction redirecting finance towards new niche technologies requires that either the niche is fit for and conforms to the financial regime s expectations or the financial regime is stretched and transformed in order to accept and finance niche technologies based on 56 interviews we identify factors that determine interactions between the financial regime and technology niches these include acceptable risk and transaction size an abundance of knowledge and heuristics in both the regime and niche and an extensive existing industry network we further analyse how state investment bank sib interventions in germany the uk and australia aimed to mobilise private finance into low carbon project development affect the interaction between the technology niche and financial regime i e whether they resulted in fitting and conforming the technological niche for the financial regime or stretching and transforming the financial regime our results point to several important effects of sib interventions with most effects fitting the niche to the regime however we also detect effects that stretch and transform the financial regime through evolutionary processes importantly some effects occur as a consequence of the primary effects based on our findings we discuss policy implications on how to accelerate transitions through policies aiming at finance as well as theoretical insights gained through our analysis

the effect of forward exchange on spot rate volatility under risk and rational expectations abstract this paper presents a multiperiod rational expectations model of a foreign exchange market in order to analyze the effect of introducing currency forward trading on measures of exchange rate volatility based on an optimizing approach to risk average agents it highlights how commercial traders and interest arbitrageurs behave facing exchange risk and forward contracting opportunities it is found that forward trading tends to stabilize spot exchange rates if the trade disturbance is the predominant random factor in the market while it exacerbates spot rate variability if the disturbance in the interest rate differential is the chief stochastic element

measuring and monitoring fuel poverty in the uk national and regional perspectives abstract throughout the industrialised world fuel poverty is the most commonly accepted term with which to describe a household s inability to afford basic standards of heat power and light whilst the term gained widespread acceptance with the publication of the uk s fuel poverty strategy in 2001 little is known about the origins of the term itself this paper traces the earliest formulations of the concept focusing particularly on the 10 needs to spend threshold which was adopted in 1991 and remains in place some 20 years later this paper argues that understanding more about the origins of this threshold yields a more critical understanding of why fuel poverty targets in the uk have not been reached and enables a more informed approach to setting realistic targets for the future it also provides an opportunity to explore regional disparities in uk fuel poverty prevalence highlighting the extent to which rigid adherence to a 10 threshold has created an unstable regional mosaic of over estimation and under estimation

making sense of institutions as a factor shaping economic performance abstract there has recently been a resurgence of interest in how institutions affect economic performance a review of this literature reveals that the concept of an institution means different things to different scholars both within economics and across the social sciences we discuss what factors unify the different definitions of institutions and develop a concept of institutions useful for the analysis of economic performance and economic growth in particular specifically we develop the notion of institutions as standard social technologies economic growth results from the co evolution of physical and social technologies

metering eu policy and implications for fuel poor households abstract fuel poverty is a function of household energy consumption income and the cost of delivered energy the paper discusses ways in which current eu policy on the development of smart metering could affect fuel poor households the main focus is on developments in electricity metering and the development of active demand and smart grids so that demand can be matched closely with available supply advances in metering and related technologies open the way to time of use charging easier switching between suppliers and between credit payment and prepayment direct load control of some end uses by the utility greater scope for microgeneration and improved consumption feedback for customers these options open up both uncertainties and risks the paper offers definitions and discussion of various functions of smart metering summarizes the eu policy background and considers some possible equity implications of rolling out a new generation of meters there follows an assessment of potential implications to the fuel poor of changes to metering based on a review of the literature on energy feedback tariffing and supplier customer relationships much of the discussion is based on the uk experience with examples from other eu member states and where appropriate from other parts of the world

definitions of fuel poverty implications for policy abstract this paper outlines why the definition of fuel poverty is important in policy formulation and describes how the government s current definitions evolved from the original concept it discusses the determination of income and fuel costs and the possibilities for a relative and common european measure it examines problems inherent in assessing fuel costs as a percentage of income and puts forward the arguments for a budget standard approach the paper illustrates how the size of the problem depends on the definition and chosen threshold and suggests advantages for a rating scale it illustrates how the income composition and thresholds also govern the distribution of the target populations and the relative importance of the main causal factors and examines the consequent policy implications it explores the definition of vulnerable households and the importance of severity and questions whether the uk fuel poverty strategy is targeted at households least able to afford their fuel costs as the name implies or primarily those at risk from excess winter and summer mortality and morbidity finally after examining the role of supplementary indicators it looks at the opportunities for changing the definition and comments on the government review of the definition and targets

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

the lack of strategic sustainability orientation in german water companies abstract water supply and distribution companies wsc are dealing with one of the most crucial natural resources that is why the german national sustainability strategy highlights water as one of the priority fields of action in germany wsc show characteristics of natural monopoly the distinct separation between public institutions and the private sector as well as municipal operators being responsible for practicing special functions is characteristic for the german water economy from an evolutionary perspective it is of interest how german wsc implement sustainability strategically therefore strategic concepts and tools facing sustainability e g iso 14001 reporting and balanced scorecard etc were analysed and evaluated in the context of the water industry using literature studies and web analysis the relevant data of 110 german wsc was put together a cross sectional design was used in order to find patterns possible gaps are highlighted and ongoing steps to foster sustainability are stressed this study points out a sustainable management is just marginally implemented the results obviously show that there are differences between large companies and smes facing sustainability requirements wsc having own regenerative power generation and an integrative thinking of farming and water supply are part of good practice

business model innovation in electricity supply markets the role of complex value in the united kingdom this research investigates the new opportunities that business model innovations are creating in electricity supply markets at the sub national scale these local supply business models can offer significant benefits to the electricity system but also generate economic social and environmental values that are not well accounted for in current policy or regulation this paper uses the uk electricity supply market to investigate new business models which rely on more complex value propositions than the incumbent utility model nine archetypal local supply business models are identified and their value propositions value capture methods and barriers to market entry are analysed this analysis defines complex value as a key concept in understanding business model innovation in the energy sector the process of complex value identification poses a challenge to energy researchers commercial firms and policymakers in liberalised markets to investigate the opportunities for system efficiency and diverse outcomes that new supplier business models can offer to the electricity system

the role of regulatory learning in energy transition the case of solar pv in brazil abstract an important problem that has attracted significant amount of attention within the context of energy transitions is the carbon lock in a situation in which energy systems are locked in to high carbon technologies through a path dependent process several measures to avoid the carbon lock in involve technology specific measures which in turn implies that those measures may result in an energy system locked in to certain low carbon technologies we consider that the brazilian system needs policies to escape the carbon lock in which are based on providing incentives to low carbon technologies we develop an analytical framework to analyze the role of regulatory institutions in the possible lock in to utility scale photovoltaic in the sense that they create barriers to the adoption of distributed generation photovoltaic we show that the definition of a process to adapt the institutional framework in a context of stress in the innovation system is crucial for the adoption of new technologies applying our framework to the brazilian power sector we observe that only when regulators consider the possibility that the system is locked in to centralized production technologies and not when they just consider the carbon lock in they manage to eliminate barriers to distributed generation based on solar pv

the hygienic transition from cesspools to sewer systems 1840 1930 the dynamics of regime transformation this article addresses the topic of transition and system change and proposes endogenous regime transformation as alternative transition path to technological substitution using sociological and institutional insights the dynamics of regime transformation are conceptualised two characteristics are pressure from outsider groups and adjustments in cognitions norms and formal rules enacted by regime insiders the transformation perspective is illustrated with a historical case study the hygienic transition from cesspools to integrated sewer systems in the netherlands the case study is used to make additions to the transformation perspective particularly with regard to tactical and strategic games

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

towards a new complexity economics for sustainability some of the most important and urgent topics requiring economic analysis and policy advice are the problems of climate change and environmental sustainability and what can be done to alter corporate and individual behaviour to deal with these issues neoclassical economists tend to focus on market solutions such as carbon trading drawing on ideas of perfect rationality of actors and the appropriateness of marginal analysis to link such policies to the whole range of potential actions from legislative and regulatory to changing individual behaviours requires the economy and society to be analysed in its full complexity recognising that marginal analysis can be not just irrelevant but positively harmful when the need is for systemic shifts in economic and social trajectories this article draws upon a seminar series on complexity economics to consider how heterodox economic analysis can be brought to bear on the issue of the environment to develop a realistic policy agenda for change copyright oxford university press

government control or low carbon lifestyle analysis and application of a novel selective constrained energy saving and emission reduction dynamic evolution system abstract this paper explores a novel selective constrained energy saving and emission reduction eser dynamic evolution system analyzing the impact of cost of conserved energy cce government control low carbon lifestyle and investment in new technology of eser on energy intensity and economic growth based on artificial neural network the quantitative coefficients of the actual system are identified taking the real situation in china for instance an empirical study is undertaken by adjusting the parameters of the actual system the dynamic evolution behavior of energy intensity and economic growth in reality are observed with the results in perfect agreement with actual situation the research shows that the introduction of cce into eser system will have certain restrictive effect on energy intensity in the earlier period however with the further development of the actual system carbon emissions could be better controlled and energy intensity would decline in the long run the impacts of cce on economic growth are positive government control and low carbon lifestyle play a decisive role in controlling eser system and declining energy intensity but the influence of government control on economic growth should be considered at the same time and the controlling effect of low carbon lifestyle on energy intensity should be strengthened gradually while the investment in new technology of eser can be neglected two different cases of eser are proposed after a comprehensive analysis the relations between variables and constraint conditions in the eser system are harmonized remarkably a better solution to carry out eser is put forward at last with numerical simulations being carried out to demonstrate the results

energy equity and the future of the fuel poor abstract a warm and adequately lit home is considered a basic need together with access to energy consuming appliances ranging from a fridge to a tv an underlying tenet of sustainable energy is that such basic needs should be affordably met yet low incomes energy inefficient housing and appliances and high energy costs mean that roughly 10 per cent of uk households many of them elderly or with young children fail to attain this basic standard these households which would need to spend more than 10 per cent of their income to attain adequate energy services are officially defined as fuel poor their cold poorly equipped homes lead to chronic cold related health conditions exacerbate social isolation and may undermine educational achievement in addition rural areas have a disproportionately high incidence of fuel poverty this review examines the current distribution of energy consumption its social impacts and the opportunities to address fuel poverty through improvements to the housing stock it will then consider potential future developments

developing pathways for energy storage in the uk using a coevolutionary framework abstract a number of recent techno economic studies have shown that energy storage could offer significant benefits to a low carbon uk energy system as it faces increased challenges in matching supply and demand however the majority of this work has not investigated the real world issues affecting the widespread deployment of storage this paper is designed to address this gap by drawing on the systems innovation and socio technical transitions literature to identify some of the most important contextual factors which are likely to influence storage deployment specifically it uses a coevolutionary framework to examine how changes in ecosystems user practices business strategies institutions and technologies are creating a new selection environment and potentially opening up the energy system to new variations of storage for both electricity and heat the analysis shows how these different dimensions of the energy regime can coevolve in mutually reinforcing ways to create alternative pathways for the energy system which in turn have different flexibility requirements and imply different roles for storage technologies using this framework three pathways are developed user led decentralised and centralised which illustrate potential long term trajectories for energy storage technologies in a low carbon energy system

fuel poverty as injustice integrating distribution recognition and procedure in the struggle for affordable warmth bringing attention to fuel poverty as a distinct manifestation of social inequality has asserted the place of affordable warmth in the profile of contemporary rights and entitlements as such fuel poverty can be understood as an expression of injustice involving the compromised ability to access energy services and thereby to secure a healthful living environment in this paper we consider how fuel poverty may be aligned to various alternative concepts of social and environmental justice whilst recognising that fuel poverty is fundamentally a complex problem of distributive injustice we argue that other understandings of injustice are also implicated and play important roles in producing and sustaining inequalities in access to affordable warmth addressing fuel poverty has to involve seeking justice in terms of the cultural and political recognition of vulnerable and marginalised social groups and pursuing procedural justice through opening up involvement and influence in decision making processes we make this argument both in theoretical terms and through considering the experience of fuel poverty advocacy and policy development in the uk opportunities for future action may be illuminated through such interconnected justice framings as wider awareness of energy climate and poverty issues emerge

transition pathways for a uk low carbon electricity future abstract achieving long term targets for greenhouse gas emissions reductions such as the uk s legally binding target of reducing its emissions by 80 by 2050 will require a transition in systems for meeting and shaping energy service demands involving radical substitution to low carbon supply technologies and improvements in end use energy efficiency this paper describes the development and high level analysis of a set of transition pathways to a uk low carbon electricity system explaining key features of the core pathways developed and the distinctiveness and value of the approach the pathways use an action space concept to explore the dynamic interactions between choices made by actors which are influenced by the competing governance framings or logics that different actors pursue the paper sets out three core transition pathways market rules central co ordination and thousand flowers in which market government and civil society logics respectively dominate it summarises the key technological and institutional changes in these pathways and the roles of actors in bringing these about this leads to an identification of the key risks to the realisation of each of the pathways and of the challenges for individuals businesses social movements and policy makers in taking action to bring them about and sustain them

perceived barriers and policy solutions in clean energy infrastructure investment international political negotiations and national policy for climate change mitigation are increasingly focussed on the mobilisation and scale up of investments in clean energy infrastructure this paper aims to develop the understanding of how institutional investors in the private sector perceive barriers to scaling up investment into clean energy infrastructure and what policy solutions to those barriers they advocate this paper adds to existing scientific knowledge through a clear focus on private sector perceptions through the analysis of previous public statements from organisations and coalitions in the finance sector a number of investment barriers were identified these initial barriers fed into a delphi process the outputs of the delphi process were categorized into five sets of barriers and a number of policy solutions associated with investing into clean energy solutions we conclude that there is a need for better engagement with the institutional investment community to ensure further effort on policy development that underpins investments at scale is effective and efficient

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

the dynamic implications of increasing returns technological change and path dependent inefficiency this paper addresses the issue of path dependent selection and inefficiency counterfactual methods and the empirical evidence employed in this research trajectory the general message is basically that the theoretical argument to prove path dependent inefficiency is relatively straightforward while empirical demonstrations as well as the analysis of welfare implications are much more difficult in the first section we briefly state the basic argument explaining how localized learning leads to an incomplete exploration of the variety distribution of a technology we then synthesize the most interesting historical studies which get potential regret results and ask whether these results suggest a large welfare loss to try to answer this question we start from the critical arguments of liebowitz and margolis to discuss the theoretical and empirical difficulties of establishing path dependent inefficiency
