the role of transnational dimensions in emerging economy technological innovation systems for clean tech the technological innovation system tis framework and its system functions have become a popular analytical tool for the study of clean tech innovation there is increasing attention for the role of emerging economies in global clean tech innovation but the applicability of tis to emerging economies cases is not entirely straightforward a key issue is the limited geographical considerations in particular transnational dimensions in tis whereas earlier perspectives on innovation in emerging economies have stressed the role of such transnational dimensions this paper elaborates transnational tis actor networks and institutions categorizes these in relation to tis functions and describes their potential to induce or block tis development in emerging economies we draw on insights from the perspectives of national learning systems international technology transfer and global production networks for this purpose we conclude that the potential effects of these transnational dimensions may be accurately grasped by the existing list of system functions lending credence to its further application of the tis framework on emerging economy case studies policy makers in emerging economies should recognize these transnational dimensions and seek to optimize their potential effect on domestic tis development taking in to consideration a realistic assessment of its role in the global tis

the price of innovation new estimates of drug development costs the research and development costs of 68 randomly selected new drugs were obtained from a survey of 10 pharmaceutical firms these data were used to estimate the average pre tax cost of new drug development the costs of compounds abandoned during testing were linked to the costs of compounds that obtained marketing approval the estimated average out of pocket cost per new drug is us 403 million 2000 dollars capitalizing out of pocket costs to the point of marketing approval at a real discount rate of 11 yields a total pre approval cost estimate of us 802 million 2000 dollars when compared to the results of an earlier study with a similar methodology total capitalized costs were shown to have increased at an annual rate of 7 4 above general price inflation 2003 elsevier science b v all rights reserved

diffusion of rural innovations some analytical issues and the case of wood burning stoves abstract the literature on the diffusion of rural innovations in third world countries reveals a spectrum of approaches to the diffusion process it is argued here that the effectiveness of a particular approach in the diffusion of particular innovations would depend on the technical the economic and the social characteristics of the innovations a typology of innovations in terms of these characteristics has been drawn up this provides the analytical framework within which the instance of wood burning stoves is concerned a priori the characteristics of this innovation are seen to be such as to necessitate the close involvement of the users in the design process itself they point to the likely inappropriateness of the usual top down approach to diffusion available evidence relating to actual experience with promoting wood burning stoves is seen to bear this out

the sources of divergent practices in china s nuclear power sector abstract unlike markets that were early developers of reactors which are dominated by single technologies china s nuclear power sector adopts and imports multiple technologies even after the chinese government introduced a policy to develop a standardized unified and technologically advanced nuclear power sector in the early 2000s different technologies continue to be imported this study uses an institutional lens to explore the decoupling of policy intentions and implementation the three phases of nuclear technology imports that occurred between the 1980s and 2010 are examined and compared data are collected from multiple sources including the diary of a major decision maker news articles project websites a regulation database domestic journal articles and interviews with industry experts using interactive content analysis this study identifies the multiple policy principles and goals of different domains that led to different import arrangements and interpretations of the available foreign technology new arrangements do not replace but overlap the existing ones that are perpetuated by the actors who benefit from them the results show that the multiplicity of china s nuclear power sector coupled with the government s late attempts at standardization contributes to diversified policy implementation they provide important policy implications for the sustainable development of the sector

the quantity and quality of life and the evolution of world inequality gdp per capita is usually used to proxy for the quality of life of individuals living in different countries welfare is also affected by quantity of life however as represented by longevity this paper incorporates longevity into an overall assessment of the evolution of cross country inequality and shows that it is quantitatively important the absence of reduction in cross country inequality up to the 1990s documented in previous work is in stark contrast to the reduction in inequality after incorporating gains in longevity throughout the post world war ii period health contributed to reduce significantly welfare inequality across countries this paper derives valuation formulas for infra marginal changes in longevity and computes a full growth rate that incorporates the gains in health experienced by 96 countries for the period between 1960 and 2000 incorporating longevity gains changes traditional results countries starting with lower income tended to grow faster than countries starting with higher income we estimate an average yearly growth in full income of 4 1 percent for the poorest 50 percent of countries in 1960 of which 1 7 percentage points are due to health as opposed to a growth of 2 6 percent for the richest 50 percent of countries of which only 0 4 percentage points are due to health additionally we decompose changes in life expectancy into changes attributable to 13 broad groups of causes of death and three age groups we show that mortality from infectious respiratory and digestive diseases congenital perinatal and ill defined conditions mostly concentrated before age 20 and between ages 20 and 50 is responsible for most of the reduction in life expectancy inequality at the same time the recent effect of aids together with reductions in mortality after age 50 due to nervous system senses organs heart and circulatory diseases contributed to increase health inequality across countries

the prospects of renewable energy technologies for rural electrification a review from nepal abstract utilization of renewable energy technologies remains one of the major energy policies throughout the world these technologies are proven to be successful for electrifying rural communities especially in developing countries realizing the benefits of renewable energy sources the government of nepal has initiated the production and distribution of renewable energy technologies in recent years mainly to electrify rural communities although these technologies are suitable for providing electricity in isolated and remote rural areas their implementation programs have not been successful as expected this review provides broad spectrum view about the energy situation in nepal and highlights the current policies and subsidies for the optimal utilization of renewable energy resources in isolated and poor rural communities in addition major promotional barriers for their implementation in nepal have been discussed

capital as a layer cake a systems approach to capital and its multi level structure abstract we elaborate a systems approach to the nature of capital that develops the work of menger and lachmann the ml trajectory we propose a layer cake metaphor to capture the kernel of the ml approach and contrast it with the neoclassical metaphor of capital as an amorphous homogeneous jelly according to the ml approach capital is combinatorial and is organized structurally and relationally the approach examines capital as it exists out there in the world as it is actually formed and experienced by entrepreneurs capital goods only exist and become productive once they are connected in entrepreneurs production plans so that the focus is upon relations of complementarity between heterogeneous capital goods as used in production hence capital has a layered structure there is a nested hierarchy of capital goods capital combinations and economy wide capital structures using bunge s theory of systems we investigate how each of these entities is a concrete system at a different layer of economic reality both capital combinations and overall capital structure arise in an irreversible causal genetic process in real time and capital structure has the added distinction of being an emergent spontaneous order

the socio technical barriers to solar home systems shs in papua new guinea choosing pigs prostitutes and poker chips over panels this study explores the socio technical barriers to solar home systems shs in papua new guinea the authors collected primary data through semi structured research interviews conducted over the course of february 2010 april 2010 respondents included government officials financiers planners commercial distributors and companies teachers and rural villagers in addition to members of civil society academics consultants and trainers these interviews were supplemented with site visits to port moresby goroka and madang and field research in the villages of akameku asaroka lufa kundiawa okifa simbu and talidig the study draws from these interviews and visits to discuss four types of barriers technical barriers relate to substandard equipment and logistical problems economic barriers include high rates of poverty misconceptions about the role of currency and lack of financing political barriers include poor institutional capacity and a government commitment to fossil fueled grid electrification social barriers encompass unrealistic expectations about what shs can provide along with jealousy theft vandalism and unfamiliarity with solar technology

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

competition among hospitals we examine competition in the hospital industry in particular the effect of ownership type for profit not for profit government we estimate a structural model of demand and pricing in the hospital industry in california then use the estimates to simulate the effect of a merger california hospitals in 1995 face an average price elasticity of demand of 4 85 not for profit hospitals face less elastic demand and act as if they have lower marginal costs their prices are lower than those of for profits but markups are higher we simulate the effects of the 1997 merger of two hospital chains in san luis obispo county where the merger creates a near monopoly prices rise by up to 53 and the predicted price increase would not be substantially smaller were the chains not for profit

power sector reform in small island developing states what role for renewable energy technologies abstract due to various pressures and desires more and more developing countries embark on power sector reform programmes yet there are a wide range of reform options and at present insufficient evidence is available as to which path will deliver best the desired objectives presently most small island developing states sids are dependent on high cost fossil fuel imports for power generation in spite of evidence that harnessing abundant domestic renewable sources of energy can deliver environmental social and economic benefits however depending on the type of power sector reform the transition towards renewable energy technologies rets can be either undermined or facilitated the specific focus on sids is justified because they have inherent characteristics that limit the degree to which the power sector can be transformed in comparison to larger continental developing countries with specific reference to sids this manuscript reviews the drivers and desires for power sector reform as well as presenting the available reform options and their implications on the up take of rets in addition to elaborating aspects of market governance other barriers to the consideration of rets such as financial bias in investment human capacity and environmental policy are discussed in view of this discussion which is based on evidence from recent reform programmes and theoretical academic literature recommendations are formulated that discourage full privatisation of the power sector as well as proposing less dogmatic lending conditions by international assistance bodies

from simplistic to complex systems in economics the applicability of complex systems theory in economics is evaluated and compared with standard approaches to economic theorising based upon constrained optimisation a complex system is defined in the economic context and differentiated from complex systems in physio chemical and biological settings it is explained why it is necessary to approach economic analysis from a network rather than a production and utility function perspective when we are dealing with complex systems it is argued that much of heterodox thought particularly in neo schumpeterian and neo austrian evolutionary economics can be placed within a complex systems perspective upon the economy the challenge is to replace prevailing simplistic theories based in constrained optimisation with simple theories derived from network representations in which value is created through the establishment of new connections between elements

the kinetics of capital formation and economic organisation we examine the inseparability of capital formation and economic organisation in capitalist economic systems capital possesses a complex multilevel micro meso macro structure that is always in the process of transformation levels of the capital structure are interdependent and interactive correspondingly economic organisation at these various levels is not an independent entity in itself it occurs as a by product and structural aspect of capital formation rather than the transaction our focal unit of analysis is a production notion the capital combination that emanates from the kinetic organisation of material by human agency we consider the behaviour of entrepreneurs as causal agents in specifying and appraising potential capital combinations reorganising production and scrapping capital entrepreneurs combinatorial actions often change existing materials to serve functions for which they were not originally designed thereby changing capital structures and the shape and boundaries of economic organisation at different levels of economic complexity capital is created in a dynamic knowledge generation process that depends on entrepreneurs perceptions of gaps in the capital structure copyright the author 2012 published by oxford university press on behalf of the cambridge political economy society all rights reserved oxford university press

review of barriers to the dissemination of decentralized renewable energy systems abstract this paper reviews the available literature dealing with the barriers to the dissemination of decentralized renewable energy systems decentralized renewable energy systems may face a range of technical economic institutional socio cultural and environmental barrier to their dissemination in the paper barriers impeding the dissemination of decentralized renewable energy systems have been identified and assessed in addition appropriate remedial measures and corresponding responsibility centers as reported in the literature have also been discussed inappropriateness of technology unavailability of skilled manpower for maintenance unavailability of spare parts high cost lack of access to credit poor purchasing power and other spending priorities unfair energy pricing lack of information or awareness and lack of adequate training on operation and maintenance of decentralized renewable energy systems are found to be the most critical barriers long term conducive policies appropriate regulatory framework financial incentives capital subsidies and soft loans to users technology and skill development internalization of externalities in the cost of energy withdrawal of subsidies presently being given to fossil fuels development of specialized institutions cooperation with international agencies participation of local community and awareness generation have been recommended for increased dissemination of decentralized renewable energy systems

financing led solar home systems in developing countries abstract about 1 4 billion people around the world still do not have access to the regular electricity it is estimated that roughly 85 of the people without electricity live in rural semi urban or remote rural areas of the sub saharan africa and south asia although grid expansion is a vital objective of several developing countries and could be a long term solution the remoteness isolation low electricity demand of many rural communities high investment cost of grid expansion make them very unlikely to be reached by the extension of the power grid consequently the off grid generation systems seem to be the most suited alternative to provide the electricity services to these isolated rural communities solar home systems shss with light emitting diode led lamps are considered to be cost effective and robust decentralized option for rural electrification two financing schemes fee for service and micro credit system ownership are primarily important for acquiring the shss by the rural population however high upfront cost of shss and absence of payment flexibility is deterring the penetration into larger market of lower income group rural population non availability of facile finance to rural population at the grass root level is the major barrier inhibiting the widespread adoption of solar powered lighting systems micro finance institutions mfis can be useful to address the gap between the high initial upfront cost of shs and low paying capacity of rural households by providing flexible and affordable credit the one stop shop model based on a single micro energy provider who provides the services of finances supply of standardized shss and after sale energy services is crucial the success of the shs program depends on the satisfactory technical performance an adequate financing infrastructure responsive after sales support and the extent to which it can fulfill the needs of the end users of having grid quality energy

what is challenging renewable energy entrepreneurs in developing countries this paper cumulates the findings from a review of the challenges faced by renewable energy entrepreneurs in developing countries to date research that could facilitate the success of renewable energy entrepreneurs in the world s developing regions has been fragmented across two main bodies of literature management specifically entrepreneurship and renewable energy by conducting a qualitative review of the extant literature i propose that the findings from both bodies of research may be distilled to six 6 key challenges inadequate access to institutional finance the price of renewable energy technologies rets the lack of skilled labour underdeveloped physical infrastructure and logistics power dominance of incumbents inadequate government or policy support through this research i not only advance a unified conceptualisation of the challenges faced by renewable energy entrepreneurs in developing countries but also highlight a number of the revealed opportunities for future research

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 diffusion in the presence of supply restrictions innovation diffusion models are developed to represent the spread of a new product from its manufacturers to its ultimate users in the marketplace however the growth of a new product can be retarded by supply restrictions such as the unavailability of the product due to limitations on the production capacity or difficulties encountered in setting up distribution systems in the presence of supply restrictions diffusion models must be developed to capture the dynamics of supply restrictions and to allow management to evaluate the impact of such supply restrictions on the growth of a new product in the market place based on the bass innovation diffusion model the objective of this paper is to suggest a parsimonious diffusion model that integrates the demand side dynamics with the supply side restrictions the sensitivity of innovation diffusion patterns in the presence of supply restrictions is examined an application examining the diffusion of new telephones in israel is documented to illustrate the usefulness of the proposed model

emergence and complexity in austrian economics abstract emergence is often argued to be a deep property of complex systems with such systems exhibiting wholes that are in some way greater than the sum of their parts these ideas have played an important part in discussions of spontaneous order within austrian economics particularly by hayek drawing on arguments dating from mill and menger although with other traditions such as that of bohm bawerk not relying on such ideas philosophical discussions of these terms are considered that raise questions about the relationship between the emergent whole and the lower level parts that comprise it a major issue is the role of these ideas and processes within evolution with hayek in particular moving strongly towards identifying their linkage something advocated by many non austrian economists and non economists as well

are new institutional economics enough promoting photovoltaics in india s agricultural sector solar photovoltaic pv technology can bring emissions free electricity to rural areas without access to the grid currently policymakers are seeking ways to expand markets for off grid pv from solar home systems to productive uses in order to enhance income generation and contribute to social development this paper explores the role of the state in promoting such market growth as a start the state must improve institutions thus echoing popular recommendations based in new institutional economic theory nie that are currently touted by the world bank and other large development agencies yet nie s framework may be insufficient because it fails to offer viable solutions to overcoming political barriers that contribute to technological path dependency a case study in punjab india where an agricultural pv water pumping program showed promising signs of successful market penetration in its first 3 years of operation illustrates how the nie s shortcomings manifest themselves in practice the program was beginning to penetrate market entry for pv pumps via competition between pv providers however the government of india achieved this feat by providing subsidies to wealthy farmers a move that is frowned upon by the nie school based on findings from the case study states should look beyond nie s framework to expand and improve pv markets in productive uses by accounting for political constraints assessing how pv technology can improve development goals and cultivating locally appropriate service delivery models

solar energy markets economics and policies abstract solar energy has experienced phenomenal growth in recent years due to both technological improvements resulting in cost reductions and government policies supportive of renewable energy development and utilization this study analyzes the technical economic and policy aspects of solar energy development and deployment while the cost of solar energy has declined rapidly in the recent past it still remains much higher than the cost of conventional energy technologies like other renewable energy technologies solar energy benefits from fiscal and regulatory incentives including tax credits and exemptions feed in tariff preferential interest rates renewable portfolio standards and voluntary green power programs in many countries the emerging carbon credit markets are expected to provide additional incentives to solar energy deployment however the scale of incentives provided by the existing carbon market instruments such as the clean development mechanism of the kyoto protocol is limited despite the huge technical potential the development and large scale deployment of solar energy technologies world wide still has to overcome a number of technical financial regulatory and institutional barriers the continuation of policy supports might be necessary for several decades to maintain and enhance the growth of solar energy in both developed and developing countries

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

roles and potentials of renewable energy in less developed economies the case of nepal increasing the share of renewable energy in the national energy mix remains one of the major energy policy goals across many economies this paper assesses the roles and potentials of renewable energy sources in less developed economies while citing nepal as an example renewable energy has a significant role to play in the electrification of rural areas in developing economies and contribute towards sustainable development realizing full potentials of renewable however requires addressing both the associated demand side and supply side constraints innovative subsidies and tax incentives adequate entrepreneurial support strengthening institutional arrangement and promoting local community based organizations such as the cooperatives are the necessary factors in promoting the green technologies in countries like nepal international factors such as large scale investment and adequate technology transfer are equally crucial to create a rapid spread and increase affordability of decentralized renewable energy technologies in less developed economies

global policy of rural electrification energy poverty and lack of electricity in the rural area exacerbate the poverty of the developing countries the sustainable renewable technologies can be considered as efficient tools to reduce energy poverty whenever they are conducted based on an appropriate policy electricity can improve the human s lifestyle by increasing the level of health education welfare and technology currently sub sahara africa with only 14 2 of rural electrification has the first rank in the world with lowest access to electricity in that region around 585 million citizens has almost no access to electricity the present study focuses on the general global policies to electrify the rural areas in this regard variety of plans and programs conducted by governmental and private institutes are investigated in the year 2011 the international energy agency iea has developed three global strategies based on the world energy market that defines the overall world energy approach in the present work different technologies for rural electrification are taken into account in two major categories of grid connected and off grid systems furthermore based on sustainable development with emphasis on environmental consideration the feasibility of electrification by using different types of renewable energies such as solar biomass hydro wind and wave have been studied despite reliability of grid connection results indicate that renewable energy sources are the best choice especially in areas far from grid connections challenges between financial institutes and executive agencies result in resource management and technology development in order to overcome existing barriers and issues

forms of emergence and the evolution of economic landscapes abstract over the past two decades the notion of emergence has attracted increasing attention and controversy across the social science including economics within this context as economic geographers our concern in this paper is with the usefulness of the idea of emergence for studying the economic landscape and its evolution the paper considers in what sense geographical processes and places can legitimately be described as emergent how such places themselves produce emergent effects and how we should conceive of and study the emergent space economy to do this we apply deacon s 2006 models of first order second order and third order emergence and trace through their implications for constructing an emergence perspective in economic geography the notion of third order emergence is argued to be the most promising since it focuses explicitly on emergence as an evolutionary process what is evident however is that a notion developed mainly for applications in physical and biological systems requires further elaboration and exploration if it is to provide explanatory leverage in studying the evolution of economic landscapes

world bank gef solar home systems projects experiences and lessons learned 1993 2000 abstract twelve projects provide energy services to off grid rural households in developing countries by enhancing markets for solar home systems and by removing barriers to their dissemination project approaches are reviewed along with early implementation experience and lessons suggested by experience most projects incorporate the following features pilot private sector and ngo delivery models pilot consumer credit delivery mechanisms pay first cost subsidies and offer affordable system sizes support policy development and capacity develop codes and standards and establish certification testing and enforcement institutions and conduct consumer awareness and marketing programs most projects are just beginning implementation a few are almost completed lessons from early experience suggest that solar home system delivery firms face a myriad of difficulties operating in rural areas credit risk is a serious concern of both financiers and dealers and makes credit sales particularly challenging technical performance of systems is becoming well proven customers desire a range of component options and service levels and can benefit from even small systems projects must recognize the link between rural electric grid extension and solar home system demand and marketing campaigns can be extremely costly and time consuming in rural areas challenges are to demonstrate sustainable and replicable business models develop regulatory models for energy service concessions and integrate rural electrification policy with solar home system delivery

using contingent behavior analysis to measure benefits from rural electrification in developing countries an example from rwanda hundreds of millions of people in sub saharan africa do not have access to electricity and will not receive it from national grids in the next few decades electricity makes up an important component of rural development and so increasing access can have positive socioeconomic benefits in this study we use contingent behavior analysis to quantify the potential benefits of electricity in rural rwandan villages which currently do not have electricity the proposed method allows for calculation of net benefits as well as electricity bills we find that even relatively poor isolated households would pay for electricity though amounts vary across households and this affects the financial viability of electrification common uses for electricity include lighting battery charging and agricultural processing despite heterogeneity opportunities exist to improve rural economic welfare through increased electricity access

learning to lend for off grid solar power policy lessons from world bank loans to india indonesia and sri lanka abstract the world bank has sought to advance the diffusion of solar photovoltaic pv technology for off grid applications in the developing world as these systems are fundamentally different to centralised power stations and conventional rural electrification the world bank has been learning how best to lend for such technology this study seeks to highlight the lessons learnt from the world bank s first loans for off grid pv to india indonesia and sri lanka it uses lifetime cost analysis to justify continued intervention in this sector and it draws on theories of innovation diffusion to guide analysis and ultimately policy recommendations because of the special role of entrepreneurial start up companies in the rural pv sector the paper also uses a company cash flow model to demonstrate the efficacy of various supply side policies finally the study concludes with a checklist of policy lessons and a consideration of the role of the international finance corporation in this sector

technology growth and expenditure growth in health care in the united states health care technology has contributed to rising survival rates yet health care spending relative to gdp has also grown more rapidly than in any other country we develop a model of patient demand and supplier behavior to explain these parallel trends in technology growth and cost growth we show that health care productivity depends on the heterogeneity of treatment effects across patients the shape of the health production function and the cost structure of procedures such as mris with high fixed costs and low marginal costs the model implies a typology of medical technology productivity i highly cost effective home run innovations with little chance of overuse such as anti retroviral therapy for hiv ii treatments highly effective for some but not for all e g stents and iii gray area treatments with uncertain clinical value such as icu days among chronically ill patients not surprisingly countries adopting category i and effective category ii treatments gain the greatest health improvements while countries adopting ineffective category ii and category iii treatments experience the most rapid cost growth ultimately economic and political resistance in the u s to ever rising tax rates will slow cost growth with uncertain effects on technology growth

economic emergence an evolutionary economic perspective abstract the standard neoclassical approach to economic theorising excludes by definition economic emergence and the related phenomenon of entrepreneurship we explore how the most economic of human behaviours entrepreneurship came to be largely excluded from mainstream economic theory in contrast we report that evolutionary economists have acknowledged the importance of understanding emergence and we explore the advances that have been made in this regard we go on to argue that evolutionary economics can make further progress by taking a more naturalistic approach to economic evolution this requires that economic analysis be fully embedded in complex economic system theory and that associated understandings as to how humans react to states of uncertainty be explicitly dealt with we argue that knowledge because of the existence of uncertainty is to a large degree conjectural and thus is closely linked to our emotional states our economic behaviour is also influenced by the reality that we and the systems that we create are dissipative structures thus we introduce the notions of energy gradients and knowledge gradients as essential concepts in understanding economic emergence and resultant economic growth

the value of life and the rise in health spending over the past half century americans spent a rising share of total economic resources on health and enjoyed substantially longer lives as a result debate on health policy often focuses on limiting the growth of health spending we investigate an issue central to this debate is the growth of health spending a rational response to changing economic conditions notably the growth of income per person we develop a model based on standard economic assumptions and argue that this is indeed the case standard preferences of the kind used widely in economics to study consumption asset pricing and labor supply imply that health spending is a superior good with an income elasticity well above one as people get richer and consumption rises the marginal utility of consumption falls rapidly spending on health to extend life allows individuals to purchase additional periods of utility the marginal utility of life extension does not decline as a result the optimal composition of total spending shifts toward health and the health share grows along with income in projections based on the quantitative analysis of our model the optimal health share of spending seems likely to exceed 30 percent by the middle of the century

financing energy access and off grid electrification a review of status options and challenges abstract this paper provides a review of funding needs and financing mechanisms for energy access in general and off grid electrification in particular to find whether the funding for these activities has been adequate whether sufficient funding is likely to be available to meet the needs of universal energy access whether innovative approaches can be used in funding it finds that in all successful cases the state has played an important role in funding infrastructure investments but many developing countries have neglected the energy access issue for a long time international donor agencies have provided selective and limited support while the innovative mechanisms are also unfriendly towards small scale projects weak governance limited organisational capacity and unfavourable policy environment militate against large scale mobilisation of financial resources in the poorest countries of the world where energy access is a chronic problem the challenge of mobilising finance and ensuring its appropriate delivery and use remains a major issue and would require a co ordinated effort of all relevant stakeholders

the viability of solar photovoltaics abstract this paper summarises the contributions to a special issue of energy policy aiming to assess the viability of solar photovoltaics pvs as a mainstream electricity supply technology for the 21st century it highlights the complex nature of such an assessment in which technical economic environmental social institutional and policy questions all play a part the authors summarise briefly the individual contributions to the special issue and draw out a number of common themes which emerge from them for example the vast physical potential of pvs the environmental and resource advantages of some pv technologies and the fluidity of the market most of the authors accept that the current high costs will fall substantially in the coming decade as a result of improved technologies increased integration into building structures and economies of scale in production in spite of such reassurances energy policy makers still respond to the dilemma of pvs with some hesitancy and prefer to leave its evolution mainly in the hands of the market this paper highlights two clear dangers inherent in this approach firstly that short term cost convergence may not serve long term sustainability goals and secondly that laggards in the race to develop new energy systems may find themselves faced with long term penalties

notions of order and process in hayek the significance of emergence this article explores the notions of order and process to which friedrich hayek subscribed it is argued that a satisfactory understanding of hayek s conceptions of order and process and in particular a clear understanding of those how the two concepts relate to each other in his scheme of thought requires an appreciation of the ontological categories of emergence and emergent properties ultimately for hayek the capacity of liberal market economies to co ordinate people s actions in the face of tacit and dispersed knowledge is an emergent property that arises only when people s interactions are governed by certain sets of rules this static analysis of the co ordinative powers of the market as an emergent property of a given system of rules must be supplemented by a dynamic account of the process through which the set of rules in question comes into being hayek provides such an account in his account of society as developing through a multi level evolutionary process key implications of hayek s accounts of order and process for debates about the co ordinative powers of free market economies are drawn out

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

a qualitative factor analysis of renewable energy and sustainable energy for all se4all in the asia pacific this study assesses the factors responsible for the success and failure of renewable energy access programs in bangladesh china laos mongolia nepal sri lanka india indonesia malaysia and papua new guinea based on 441 research interviews over the course of four years site visits to 90 renewable energy facilities and focus groups with almost 800 community members in 10 countries this study develops a series of overarching qualitative factors that correlate with programs that met their targets sometimes ahead of schedule and produced measurable benefits exceeding costs the inverse of these factors is associated with programs that did not meet their targets were behind schedule and or produced measurable costs exceeding benefits it concludes by offering 10 lessons for energy analysts and development practitioners concerning appropriate technology income generation financing political leadership capacity building programmatic flexibility marketing and awareness stakeholder engagement community ownership and technical standardization

the anatomy of emergence with a focus upon capital formation abstract emergence is a unifying theme of both evolutionary economics and complex systems theory in spite of this centrality emergence in economics has not been subject to an extensive critical analysis this paper remedies this deficit we identify several conditions that economic patterns i e rule systems structures must satisfy to qualify as emergent 1 material realization emergent patterns are realized in physical structures and processes 2 coherence pattern is not a mere aggregate but a systemic whole 3 non distributivity pattern possesses global properties absent from its parts 4 structure dependence systemic properties depend upon connective structure these four core features are common to all forms of emergence in economics evolutionary economic systems also exhibit extra strength versions of emergence which require that patterns possess one or more additional features 5 genuine novelty 6 unpredictability in principle and 7 irreducibility we introduce three basic forms of emergence that occur in economic systems minimal diachronic and synchronic emergence and apply these ideas to capital formation at all levels of economic order the economy wide capital structure exhibits strongly emergent properties both diachronic and synchronic that depend on its structural and functional organization it is not a mere aggregate of capital goods within the realm of capital phenomena we also compare the distinguishing characteristics of emergent and spontaneous self organizing orders we provide a case study of the iphone as an emergent capital pattern to illustrate conditions 1 7 above and the different types of emergence

photovoltaic technology markets economics and rural development abstract photovoltaic pv electricity has been widely supported as a remote energy source for developing countries in response the production and shipment of pv modules in developed nations has steadily increased through the past decade often marketed through the auspices of technology transfer and financed by international development aid this paper investigates the motives economics and development implications of pvs in rural electrification drawing on field research in the dominican republic the implications of subsidizing a pv market rather than investing in further pv research and development are explored

an integrated framework for rural electrification adopting a user centric approach to business model development rural electrification re has gained prominence over the past two decades as an effective means for improving living conditions this growth has largely been driven by socio economic and political imperatives to improve rural livelihood and by technological innovation based on a content analysis of 232 scholarly articles the literature is categorized into four focal lenses technology institutional viability and user centric we find that the first two dominate the re debate the viability lens has been used less frequently whilst the user centric lens began to engage scholars as late as 2007 we provide an overview of the technological institutional and viability lenses and elaborate upon the user centric lens in greater detail for energy policy and practice we combine the four lenses to develop a business model framework that policy makers practitioners and investors could use to assess re projects or to design future rural electrification strategies

the value of disease prevention vs treatment we present an integrated valuation model for diseases that are life threatening the model extends the standard one period value per statistical life model to three health prospects healthy ill and dead we derive willingness to pay values for prevention efforts that reduce a disease s incidence rate as well as for treatments that lower the corresponding health deterioration and mortality rates we find that the demand value of prevention always exceeds that of treatment people often overweight small risks and underweight large ones we use the rank dependent utility framework to explore how the demand for prevention and treatment alters when people evaluate probabilities in a non linear manner for incidence and mortality rates associated with common types of cancers the inverse s shaped probability weighting found in experimental studies leads to a significant increase in the demand values of both treatment and prevention

an economic evaluation of the war on cancer for decades the us public and private sectors have committed substantial resources towards cancer research but the societal payoff has not been well understood we quantify the value of recent gains in cancer survival and analyze the distribution of value among various stakeholders between 1988 and 2000 life expectancy for cancer patients increased by roughly four years and the average willingness to pay for these survival gains was roughly 322 000 improvements in cancer survival during this period created 23 million additional life years and roughly 1 9 trillion of additional social value implying that the average life year was worth approximately 82 000 to its recipient health care providers and pharmaceutical companies appropriated 5 19 of this total with the rest accruing to patients the share of value flowing to patients has been rising over time in terms of economic rates of return r d investments against cancer have been a success particularly from the patient s point of view

comparing drivers barriers and opportunities of business models for renewable energies a review abstract this article systematically reviews the emerging field of research on business models for renewable energies differentiating between developing and industrialized countries the key findings on developing countries are as follows first there is a lack of quantitative data second opportunities are driven primarily by unfulfilled basic needs and micro finance whereas corruption and weak electricity grids are the main barriers and third business models should be replicable the key findings on industrialized countries are as follows first opportunities are driven primarily by climate change mitigation and energy efficiency improvements second stuck thought patterns and high costs of energy storage are important barriers and third cooperation is a key in future business models to handle increasing complexity this review reveals implications for researchers and policy makers promising avenues for future research are the analysis of intermodal business models and opportunities concerning energy self supply and renewable district heating policy makers are advised to design legal frameworks that account for the global nature of the renewable energy challenge and are simultaneously adapted to regional disparities

an energy pricing scheme for the diffusion of decentralized renewable technology investment in developing countries the purpose of this paper is to investigate price support for market penetration of renewable energy in developing nations through a decentralized supply process we integrate the new decentralized energy support renewable premium tariff to analyze impacts of tariff incentives on the diffusion of renewable technology in senegal based on photovoltaic and wind technologies and an assessment of renewable energy resources in senegal an optimization technique is combined with a cash flow analysis to investigate investment decisions in renewable energy sector our findings indicate that this support mechanism could strengthen the sustainable deployment of renewable energy in remote areas of senegal although different payoffs emerged profits associated with a renewable premium tariff are the highest among the set of existing payoffs moreover in analyzing impacts of price incentives on social welfare we show that price tariffing schemes must be strategically scrutinized in order to minimize welfare loss associated with price incentives finally we argue that a sustainable promotion of incentive mechanisms supporting deployment of renewable technology in developing nations should be carried out under reliable institutional structures the additional advantage of the proposed methodology is its ability to integrate different stakeholders producers investors and consumers in the planning process

enabling mini grid development in rural india summary rural electrification rates in india lag behind government goals in part due to the inability of distribution companies discoms to fund central grid expansion in the absence of central grid electrification mini grids offer significant potential for an immediate pathway toward rural electrification and the attendant gains in economic growth and productivity yet private investment in mini grids has been virtually absent in india using a comprehensive life cycle cost analysis we find that mini grids based on solar pv power and storage are more economical than incumbent energy services available to households without central grid connection under current law a prospective entrepreneur in india does not require a license or certification in order to build a mini grid and subsequently provide electricity services in the area covered by said installation conversely there is no legal or regulatory framework that specifies what is to happen if the central grid were to be extended to an area that is already covered by a mini grid we report detailed survey evidence from interviews with entrepreneurs analysts and policymakers whose assessments converge on the same point mini grid investments would be jeopardized in the event of central grid extension precisely because discoms would by regulatory order provide electricity services at highly subsidized rates well below their full economic cost our fieldwork suggests that the threat of central grid extension is a gateway barrier preventing mini grid development in india the issues associated with the gateway barrier have common elements with the so called holdup problem as identified in the economics of organizations there have been two recent federal policy guidelines and one actual state level policy addressing the regulatory status of mini grids we examine the effectiveness of these policies proposals in terms of an entrepreneur s willingness to develop mini grids in the future

shackle on choice imagination and creativity hayekian foundations this paper develops a response to some of the criticisms that have been made of g l s shackle s analysis of human decision making because of its reliance on a cartesian account of the mind it is argued that the basis for a response can be found in the work on theoretical psychology developed by shackle s fellow subjectivist and one time phd supervisor f a hayek in particular the ideas advanced by hayek in his 1952 book the sensory order can be used to provide an account of the mind that avoids the shortcomings of shackle s cartesianism whilst still doing justice to his emphasis on genuine choice expectations and the role of creativity and the imagination in human decision making
