energy consumption and economic growth relationship evidence from panel data for low and middle income countries abstract this paper uses the panel data of energy consumption ec and economic growth gdp for 51 countries from 1971 to 2005 these countries are divided into three groups low income group lower middle income group and upper middle income group countries firstly a relationship between energy consumption and economic growth is investigated by employing pedroni 1999 panel cointegration method secondly panel causality test is applied to investigate the way of causality between the energy consumption and economic growth finally we test whether there is a strong or weak relationship between these variables by using pedroni 2001 method the empirical results of this study are as follows i energy consumption and gdp are cointegrated for all three income group countries ii the panel causality test results reveal that there is long run granger causality running from gdp to ec for low income countries and there is bidirectional causality between ec and gdp for middle income countries iii the estimated cointegration factor is not close to 1 in other words no strong relation is found between energy consumption and economic growth for all income groups considered in this study the findings of this study have important policy implications and it shows that this issue still deserves further attention in future research

renewable and non renewable energy growth emissions linkages review of emerging trends with policy implications abstract this study is an extension of the previous studies which focused mainly on energy growth nexus but fails to consider the carbon emission implication of this relationship the methodology of the study permits a comprehensive and comparative analysis of existing studies on renewable and non renewable energy growth emission nexus in order to draw some implications for policy and research the survey revealed the extent of the spread of studies across issues time and geographical space countries and regions it also disclosed the range of methodological approaches adopted to analyse the issues over time and the frequency of their use it unravelled the varied findings across countries and regions given the diverse methods employed and specific features of the economies analysed arising from the literature survey this study highlights the existing gaps in the literature and new direction for policy and research the general policy implication of the findings of this study is that pollution effect of energy growth nexus should be taken into consideration in policy formulation for sustainable development further the design of regional and global policies should recognise the fact that energy growth emission linkages varied across countries even in the same region some new direction for research on renewable and non renewable energy growth emission linkages pointed out in this survey includes the following future research on energy growth nexus without considering the pollution impact may not contribute so much to the literature studies should investigate the substitution complementary effects of the energy varieties on growth emission nexus while new methodological contributions are imperative

renewable energy consumption and industrial production a disaggregated time frequency analysis for the u s abstract this paper aims to analyze the interaction between renewable energy consumption and industrial production for the u s over the 1981 2018 period we contribute to the existing literature by the disaggregation of renewable energy sources hydropower geothermal and biomass by the consideration of time and frequency through wavelet techniques and the time varying granger causality test recently proposed by shi et al 2018 based on monthly data wavelet results show a positive co movement between industrial production and biomass energy consumption at low frequencies meaning in the long term only the bootstrap rolling window granger causality test indicates a bi directional predictability between renewable energy consumption and industrial production in crisis and turmoil periods only these results are found to be robust to the inclusion of control variables non renewable energy consumption and crude oil prices and to the selection of the lag length for the corresponding var model

oligopoly game price makers meet price takers abstract the paper studies an oligopoly game where firms can choose between price taking and price making strategies on a mixed market price takers are always better off than price makers though the profits of both types decline in the number of price takers we investigate and confront two possibilities of firms decisions about their types forward looking equilibrium reasoning and backward looking individual learning we find that the cournot outcome is the only equilibrium prediction and it is learnable if firms are sufficiently sensitive to profit differences however with a larger number of firms a unilateral deviation from cournot behavior becomes profitable under learning this incentive creates a space for permanent oscillations over different markets with a positive but low number of price takers

economic assessment of eucalyptus spp for biomass production as alternative crop in southern italy the increase in energy prices and the stagnation of sales prices of the main agricultural commodities required a rethinking of farm production strategies since during the last years thanks to a series of policies aimed at promoting renewable sources it has been a rapid diffusion of lignocellulosic biomass species this paper aimed at evaluating the economic feasibility of the introduction of eucalyptus eucalyptus spp as energy crop for farmers of southern italy by comparing it with traditional crop rotations in particular economic analysis has been carried out in a representative case study located in the sicilian hilly hinterland where in 2013 it has been built a biomass plant for energy production however results showed that introduction of eucalyptus for biomass production is less profitable for farmers than traditional crops considering the incompressibility of production costs and the actual market price of woodchips

energy consumption and gdp in developing countries a cointegrated panel analysis in this paper we re investigate the co movement and the causality relationship between energy consumption and gdp in 18 developing countries using data for the period 1975 to 2001 recently developed tests for the panel unit root heterogeneous panel cointegration and panel based error correction models are employed the empirical results provide clear support of a long run cointegration relationship after allowing for the heterogeneous country effect the long run relationship is estimated using a full modified ols the evidence shows that long run and short run causalities run from energy consumption to gdp but not vice versa this result indicates that energy conservation may harm economic growth in developing countries regardless of being transitory or permanent

a critical appraisal of the effectiveness of uk perennial energy crops policy since 1990 abstract energy crops are cultivated primarily for bioenergy production but can also have wider benefits to agriculture and the environment policies put in place in the uk and europe have promoted bioenergy and the growth of energy crops despite the various policy support mechanisms the cultivation of perennial energy crops has proceeded at a low rate this study rigorously analyses some of the key uk bioenergy policies since 1990 to assess why perennial energy crops have not fulfilled their potential the uk energy crops market is scrutinised and shows the industry is still nascent compared to government aspirations case studies of both successful and unsuccessful projects are evaluated to reveal how effective different policies have been in establishing uk perennial energy crops this original review shows significantly that none of the projects initiatives or schemes described can be viewed as an absolute success the main obstacles that have hindered progress include the lack of long term supportive energy crops policy the failure of headline projects and organisations the lack of competitiveness of long term perennial crop options compared to annual crops bureaucracy of schemes over ambitious projects and large scale support schemes tending to favour imported biomass rather than support domestic supply 25 years of failed energy crops policy suggests there needs to be a long term strategy future support for the sector must join up policy between different government departments to recognise multi functional benefits of perennial energy crops support mechanisms could aim to provide a competitive advantage for local supply and use and improve management of cashflows during establishment the risk burden should be shared between suppliers and end users smaller scale projects using established technologies are required with energy crops introduced in a phased manner supply side measures need to be balanced with demand side incentives to link supply with end user markets

renewable and non renewable energy use economic growth nexus the case of mena net oil importing countries abstract this study examines the energy use economic growth nexus by disaggregating energy use into two types of energy renewable and non renewable energy use our sample consists of eleven mena net oil importing countries noics during the period 1980 2012 a multivariate panel framework was used to estimate the long run relationship and the panel granger causality tests was employed to assess the causality direction among variables the empirical results provide evidence for long term equilibrium relationship between real gross domestic product gdp renewable energy use non renewable energy use real gross fixed capital formation and labor force the results provide evidence also for positive and statistically significant elasticities moreover the empirical findings from panel error correction model confirm the existence of bidirectional causality between renewable energy use and economic growth and between non renewable energy use and economic growth results that support the feedback hypothesis moreover our empirical findings provide evidence for two way bidirectional causal association in both the short and long run between renewable and non renewable energy use which proves the substitutability and interdependence between these two types of energy sources the policies implications of these results are also proposed and discussed

the relationship between gdp and electricity consumption in 10 asian countries the purpose of this study is to estimate the relationships between gdp and electricity consumption in 10 newly industrializing and developing asian countries using both single data sets and panel data procedures the empirical results from single data set indicate that the causality directions in the 10 asian countries are mixed while there is a uni directional short run causality running from economic growth to electricity consumption and a bi directional long run causality between electricity consumption and economic growth if the panel data procedure is implemented these empirical findings imply that electricity conservation policies through both rationalizing the electricity supply efficiency improvement to avoid the wastage of electricity and managing demand side to reduce the electricity consumption without affecting the end user benefits could be initiated without adverse effect on economic growth the findings on the long run relationship indicate that a sufficiently large supply of electricity can ensure that a higher level of economic growth

the causality relationship between energy consumption and gdp in g 11 countries revisited abstract this paper explores whether energy conservation policies can be implemented in countries with the same level of development that is is restraining energy consumption without compromising economic growth feasible in all industrialized countries a new granger non causality testing procedure developed by toda and yamamoto 1995 journal of econometrics 66 225 250 is applied to re investigate the relationship if any between energy consumption and income in 11 major industrialized countries the results clearly do not support the view that energy consumption and income are neutral with respect to each other except in the case of the united kingdom germany and sweden where a neutral relationship is found bi directional causality in the united states and uni directional running from energy consumption to gdp in canada belgium the netherlands and switzerland are found this indicates that energy conservation may hinder economic growth in the latter five countries further the causality relationship appears to be uni directional but reversed for france italy and japan which implies that in these three countries energy conservation may be viable without being detrimental to economic growth

electricity supply employment and real gdp in india evidence from cointegration and granger causality tests abstract this study probes nexus between electricity supply employment and real gdp for india within a multivariate framework using autoregressive distributed lag ardl bounds testing approach of cointegration long run equilibrium relationship has been established among these variables for the time span 1970 71 to 2005 06 the study further establishes long and short run granger causality running from real gdp and electricity supply to employment without any feedback effect thus growth in real gdp and electricity supply are responsible for the high level of employment in india the absence of causality running from electricity supply to real gdp implies that electricity demand and supply side measures can be adopted to reduce the wastage of electricity which would not affect future economic growth of india

the chaotic duopolists revisited the adjustment process of three oligopolists is studied under cournot and stackelberg action it is demonstrated that with an iso elastic demand function and constant marginal costs the system can result in periodic or in chaotic behaviour in particular the case with two identical and one different oligopolists is focused which turns into a virtual duopoly though displaying a wider set of bifurcations than can occur in genuine duopoly

hedonic price indexes for spreadsheets and an empirical test for network externalities in this article i first estimate hedonic price equations for computer spreadsheet programs and then use the analysis to empirically test whether network externalities exist in this industry the study shows that consumers are willing to pay a significant premium for spreadsheets that are compatible with the lotus platform and for spreadsheets that offer links to external databases and a similar premium for spreadsheets that offer local area network externalities finally the quality adjusted real price of computer spreadsheets declined by approximately 15 per year from 1986 to 1991

the relationship between energy and production evidence from turkish manufacturing industry this paper investigates the relationship between energy and production at the industry level in an emerging market turkey in a multivariate framework the electricity consumption and value added relation is examined in the turkish manufacturing industry while also accounting for labor and fixed investment we find that labor fixed investment electricity consumption and value added are related via three cointegrating vectors the vec results indicate uni directional causality running from electricity consumption to value added generalized impulse response and variance decomposition analyses confirm these results thus energy input appears to be closely related to production hence energy saving technologies and increased energy efficiency may increase the growth in manufacturing value added

the value of ideal contingency markets in agriculture an incomplete markets equilibrium in which no contingency markets are available is compared to a complete markets equilibrium formed by introducing a futures market and a crop insurance market the two regimes are compared using comparative static and welfare analyses numerical examples highlight important characteristics of the model and illustrate how the effects of introducing contingency markets can be quantified the main conclusions are that contingency markets in agriculture increase economic efficiency but there is no guarantee that farmers and consumers both benefit it is found that futures and crop insurance markets may reduce farmer welfare when the demand for farm products is price inelastic

growth and renewable energy in europe a random effect model with evidence for neutrality hypothesis this is an empirical study on the causal relationship between economic growth and renewable energy for 27 european countries in a multivariate panel framework over the period 1997 2007 using a random effect model and including final energy consumption greenhouse gas emissions and employment as additional independent variables in the model empirical results do not confirm causality between renewable energy consumption and gdp although panel causality tests unfold short run relationships between renewable energy and greenhouse gas emissions and employment the estimated cointegration factor refrains from unity indicating only a weak if any relationship between economic growth and renewable energy consumption in europe suggesting evidence of the neutrality hypothesis which can partly be explained by the uneven and insufficient exploitation of renewable energy sources across europe

renewable energy an efficient mechanism to improve gdp abstract this article analyzes the effects of renewable energy on gdp for 116 economies in 2003 through structural equation modeling sem approach in order to decipher the mechanism of how the use of renewables improves macroeconomic efficiency we decompose gdp by the expenditure approach although previous theory predicts positive effects of renewables on capital formation and trade balance the sem results show that renewables have a significant positive influence on capital formation only the result that renewables do not have a significant impact on trade balance implies that renewables do not have an import substitution effect thus we confirm the positive relationship between renewable energy and gdp through the path of increasing capital formation but not for the path of increasing trade balance

renewable energy consumption economic growth nexus in turkey abstract this paper examines the renewable energy consumption economic growth causality nexus in turkey studies in the literature can be grouped as country specific and multi country studies the results of these studies are inconsistent and there is no agreement on the existence or the direction of causality between renewable energy consumption and economic growth the results of this country specific study support conservation hypothesis the results of empirical tests from ardl approach show that renewable energy consumption has a negative impact on economic growth and the ones of toda yamamoto causality tests show that there is a unidirectional causality running from economic growth to renewable energy consumption

dynamic complexity in duopoly games abstract we discuss the occurrence of periodic and chaotic phenomena in infinite horizon duopoly games where firms maximize their discounted sum of profits and use markov perfect equilibrium strategies in the alternating case their corresponding actions are then constrained orbits of a map similar to a cournot t tonnement we show that any behavior is possible for small discount factors and that one obtains the cournot t tonnement as the discount factor goes to zero in the simultaneous case we show by mean of an example that many cournot t tonnements can be viewed as markov perfect equilibria of an infinite horizon game and that one obtains the nash equilibrium of the static game as the discount parameter goes to zero we are thus led to study in detail the dynamical properties of a cournot t tonnement

caution implies profit abstract the paper illustrates by simple cobweb models that under certain circumstances fluctuations in perpetual disequilibrium may not only be viable but also preferable to a competitive equilibrium from the long run perspective

biomass price developments inhibit biofuel investments and research in germany the crucial future role of high yields abstract the competitiveness of conventional and advanced second generation biofuels is a critical issue for the implementation of a sustainable transport strategy we model biofuel competition under different feedstock cost development scenarios assessing what costs and cost developments can be expected for energy crops in germany and how these feedstock cost developments affect the competitiveness between biofuels perennial poplar was found to be the least cost energy crop with non perennial silage maize being strongly competitive at increasing feedstock price developments assuming increasing feedstock costs for the future neither conventional biodiesel from rape seed nor advanced biodiesel were found to be competitive in the long run feedstock costs were found to overshadow all other factors leading to costs for advanced biodiesel to be between 27 0 and 53 6 gj 1 in 2030 which is above most expectations of the advanced biofuels only synthetic natural gas was cost competitive under some circumstances but biomethane from silage maize and bioethanol from sugar beet were the strongest options as they combine high yields with high conversion efficiencies while avoiding the high upfront costs of advanced biofuels and the risk of switching to perennial crops however such a transition leads to less mobile feedstocks being used than presently and in the case of gaseous fuels requires stimulation of the demand side in order to function the high dependence on and increasing relevance of feedstock costs is characteristic for the biobased renewables only and is detrimental and inhibiting for investments and research and development efforts in contrast to for e g wind and solar photovoltaics and must be considered when designing policy for any sector of the bioeconomy

audience characteristics and bundling a hedonic analysis of magazine advertising rates abstract increasingly magazines are able to offer potential advertisers all their readers pure bundling only specific reader segments pure components pricing or a combination of the two mixed bundling using data on advertising rates and reader demographics the authors estimate the implicit prices of reader characteristics within a hedonic framework the results suggest that the magnitude of the price and revenue premiums earned by unbundling a magazine s readers can be substantial

limited knowledge of demand and oligopoly equilibria abstract in a standard model of oligopoly with differentiated products the existence of an equilibrium at which the first order conditions for profit maximisation are simultaneously satisfied for all firms is proved and this is done without imposing any restrictions on the demand functions this is an equilibrium in the following sense although some firms may not necessarily be maximising their profits nevertheless if each firm s knowledge of demand is limited to the linear approximation of its own demand curve then it will believe that it is indeed maximising its profits

renewable energy consumption and income in emerging economies abstract increased economic growth and demand for energy in emerging economies is creating an opportunity for these countries to increase their usage of renewable energy this paper presents and estimates two empirical models of renewable energy consumption and income for a panel of emerging economies panel cointegration estimates show that increases in real per capita income have a positive and statistically significant impact on per capita renewable energy consumption in the long term a 1 increase in real income per capita increases the consumption of renewable energy per capita in emerging economies by approximately 3 5 long term renewable energy per capita consumption price elasticity estimates are approximately equal to 0 70

renewable and non renewable energy consumption growth nexus evidence from a panel error correction model abstract unlike previous renewable energy consumption growth studies this study examines the relationship between renewable and non renewable energy consumption and economic growth for 80 countries within a multivariate panel framework over the period 1990 2007 the pedroni 1999 2004 heterogeneous panel cointegration test show a long run equilibrium relationship between real gdp renewable energy consumption non renewable energy consumption real gross fixed capital formation and the labor force with the respective coefficient estimates positive and statistically significant there is little difference in the elasticity estimates with respect to renewable and non renewable energy consumption the results from the panel error correction model reveal bidirectional causality between renewable and non renewable energy consumption and economic growth in both the short and long run also there is bidirectional short run causality between renewable and non renewable energy consumption indicative of substitutability between the two energy sources

threshold effect of the economic growth rate on the renewable energy development from a change in energy price evidence from oecd countries this paper uses a panel threshold regression ptr model to investigate the influence that energy prices have on renewable energy development under different economic growth rate regimes the empirical data are obtained from each of the oecd member countries over the period from 1997 to 2006 we show that there is one threshold in the regression relationship which is 4 13 of a one period lag in the annual gross domestic product gdp growth rate the consumer price index cpi in so far as it relates to variations in energy is significantly positively correlated with the contribution of renewables to energy supply in the regime with higher economic growth but there is no relationship in the regime with lower economic growth therefore countries characterized by high economic growth are able to respond to high energy prices with increases in renewable energy use while countries characterized by low economic growth countries tend to be unresponsive to energy price changes when they come to their level of renewable energy

electricity consumption and economic growth in china abstract this paper applies the error correction model to examine the causal relationship between electricity consumption and real gdp for china during 1971 2000 our estimation results indicate that real gdp and electricity consumption for china are cointegrated and there is unidirectional granger causality running from electricity consumption to real gdp but not vice versa in order to overcome the constraints on electricity consumption the chinese government has to speed up the nation wide interconnection of power networks to upgrade urban and rural distribution grids and to accelerate rural electrification

causality cointegration and control abstract the first sections of the paper show that causality tests can be relevant when considering the effectiveness of a control mechanism rejecting some results in earlier papers the relevance comes from a more careful consideration of what information is available to whom and when compared to previous work the final section of the paper extends this analysis to cointegrated variables when causality is a necessary consequence

co2 emissions energy consumption and economic growth in turkey abstract this paper examines the long run and causal relationship issues between economic growth carbon emissions energy consumption and employment ratio in turkey by using autoregressive distributed lag bounds testing approach of cointegration empirical results for turkey over the period 1968 2005 suggest an evidence of a long run relationship between the variables at 5 significance level in turkey the estimated income elasticity of carbon emissions per capita is 0 606 and the income elasticity of energy consumption per capita is 1 375 results for the existence and direction of granger causality show that neither carbon emissions per capita nor energy consumption per capita cause real gdp per capita but employment ratio causes real gdp per capita in the short run in addition ekc hypothesis at causal framework by using a linear logarithmic model is not valid in turkish case the overall results indicates that energy conservation policies such as rationing energy consumption and controlling carbon dioxide emissions are likely to have no adverse effect on the real output growth of turkey

do people play nash equilibrium lessons from evolutionary game theory evolutionary game theory provides an answer to two of the central questions in economic modeling when is it reasonable to assume that people are rational and when is it reasonable to assume that behavior is part of a nash equilibrium and if it is reasonable which equilibrium the traditional answers are not compelling and much of evolutionary modeling is motivated by the need for a better answer evolutionary game theory suggests that in a range of settings agents do eventually play a nash equilibrium moreover evolutionary modeling has shed light on the relative plausibility of different nash equilibria

the effect of renewable and nonrenewable electricity generation on economic growth abstract this note examines the impact of electricity generation on economic growth using data for a panel of 174 countries over the period 1980 2012 the paper makes several contributions first contrary to much of the literature the paper focuses on the effect of electricity generation on economic growth because of transmission and distribution losses and theft not all the electricity that is generated is eventually consumed making it necessary to investigate the impact of electricity generation on growth second we disentangle the impact of total electricity generation on growth into renewable and nonrenewable effects with increasing pursuit of energy security technological advances the falling costs of renewables and the movement to exploit renewable energy sources for electrification there is need to study not only the impact of traditional sources of electricity but renewable sources as well third we deviate from previous studies that focus on granger causality and or cointegration by estimating the effect of electricity generation on growth using the system generalized method of moments gmm given that electricity generation and many of the other regressors in our model may be jointly determined with gdp growth the system gmm approach is appropriate to deal with these endogeneity issues fourth we provide evidence of a link between electricity loss and economic growth our results indicate a strong positive and statistically significant relationship between renewable and nonrenewable electricity generation and growth

oligopoly games with local monopolistic approximation we propose an oligopoly game where quantity setting firms have incomplete information about the demand function at each time step they solve a profit maximization problem assuming a linear demand function and ignoring the effects of the competitors outputs despite such a rough approximation that we call local monopolistic approximation lma the repeated game may converge at a nash equilibrium of the game played under the assumption of full information an explicit form of the dynamical system that describes the time evolution of oligopoly games with lma is given for arbitrary differentiable demand functions provided that the cost functions are linear or quadratic in the case of isoelastic demand we show that the game based on lma always converges to a nash equilibrium this result compared with best reply dynamics shows that in this particular case less information implies more stability

the coexistence of stable equilibria under least squares learning abstract in this paper we consider firms that learn about market conditions by estimating the demand function using past market data we show that learning may lead to suboptimal outcomes even when the estimated demand function perfectly fits the observations used in the regression and firms thus perceive to have learned the demand function correctly we consider the salop model with three firms and two types of consumers that differ in their sensitivity to product differences firms do not know the demand structure and they apply least squares learning to learn the demand function in each period firms estimate a linear perceived demand function and they play the perceived best response to the previous period price of the other firms this learning rule can lead to three different outcomes a self sustaining equilibrium the nash equilibrium or an asymmetric learning equilibrium in this last equilibrium one firm underestimates the demand for low prices and it attracts consumers with high sensitivity only this type of equilibrium has not been found in the literature on least squares learning before both the nash equilibrium and the asymmetric learning equilibrium are locally stable therefore the model has coexisting stable equilibria

the effect of electricity consumption from renewable sources on countries economic growth levels evidence from advanced emerging and developing economies abstract this paper uses a sample of 36 countries for the time period 1990 2011 in order to examine the relationship between countries electricity consumption from renewable sources and gross domestic product gdp levels several nonparametric techniques are applied to investigate the effect of electricity consumption from several renewable sources including wind geothermal solar biomass and waste on countries gdp levels when investigating the whole sample ignoring countries economic development status the results reveal an increasing relationship up to a certain gdp level which after that point the effect of electricity consumption on gdp stabilises however when analyzing separately the emerging markets and developing economies and the advanced developed economies the results change significantly for the case of emerging market and developing economies the relationship appears to be highly nonlinear an m shape form indicating that on those countries the levels of electricity consumption from renewable sources will not result on higher gdp levels in contrast for the case of the advanced economies the results reveal an increasing nonlinear relationship indicating that higher electricity consumption levels from renewable sources results to higher gdp levels this finding is mainly attributed to the fact that in the advanced developed economies more terawatts from renewable sources are generated and consumed compared to the emerging market and developing economies which traditionally their economies rely on non renewable sources for power generation and consumption

impact of perennial energy crops income variability on the crop selection of risk averse farmers abstract the uk government policy is for the area of perennial energy crops in the uk to expand significantly farmers need to choose these crops in preference to conventional rotations for this to be achievable this paper looks at the potential level and variability of perennial energy crop incomes and the relation to incomes from conventional arable crops assuming energy crop prices are correlated to oil prices the results suggests that incomes from them are not well correlated to conventional arable crop incomes a farm scale mathematical programming model is then used to attempt to understand the affect on risk averse farmers crop selection the inclusion of risk reduces the energy crop price required for the selection of these crops however yields towards the highest of those predicted in the uk are still required to make them an optimal choice suggesting only a small area of energy crops within the uk would be expected to be chosen to be grown this must be regarded as a tentative conclusion primarily due to high sensitivity found to crop yields resulting in the proposal for further work to apply the model using spatially disaggregated data

selection dynamics asymptotic stability and adaptive behavior selection dynamics are often used to distinguish stable and unstable equilibria this is particularly useful when multiple equilibria prevent a priori comparative static analysis this paper reports an experiment designed to compare the accuracy of the myopic best response dynamic and an inertial selection dynamic the inertial selection dynamic makes more accurate predictions about the observed mutual best response outcomes

the causal relationship between energy resources and economic growth in brazil abstract this study investigates the causal relationship between clean and non clean energy consumption and economic growth in brazil over the period of 1980 2009 clean energy consumption at aggregated level of total renewable energy consumption and disaggregated levels of hydroelectric new renewables and nuclear energy consumption are tested within a production function framework a cointegration test reveals a long term equilibrium relationship between real output capital labor and renewable and non renewable energy consumption at aggregated level and a long term equilibrium relationship between real output capital labor and hydroelectric new renewables nuclear and fossil fuel energy consumption at disaggregated level the capital labor and new renewables elasticities of real output are positive and statistically significant other energy consumption item s elasticities are insignificant the results from error correction model reveal the interdependencies between new renewables nuclear fossil fuel and total non renewable energy consumption and economic growth the unidirectional causality from hydroelectric total renewable consumption to economic growth the substitutability between new renewables and fossil fuel consumption and the substitutability between new renewables and nuclear energy consumption additionally nuclear and new renewables energy consumption responds to bring the system back to equilibrium overall aggregated analysis may obscure the relationship between different types of clean energy consumption and economic growth

farm level constraints on the domestic supply of perennial energy crops in the uk abstract there are a number of estimates of the land area that could potentially be dedicated to perennial energy crops such as short rotation coppice src willow and miscanthus in the uk but little is known about how farmers will respond to the opportunities presented by these relatively novel crops perennial energy crops face competition from other arguably more flexible uses of farmland and if not seen as attractive propositions to individual farmers they will not be grown farmers decisions are therefore a key constraint on potential supply this paper reviews the policy background and considers whether policy is based on any consideration of likely supply response before presenting outcomes of focus groups composed of farmers who already grow or are considering growing perennial energy crops there appear to be a number of barriers to adoption in addition to concerns over the security of contracts the current high wheat price increases the opportunity cost of committing land to perennial energy crops there are also worries about the impact of willow roots on field drains and the cost of returning the land to other uses this paper outlines a number of issues of importance to policy makers and suggests future research needs

the prices of classical recorded music a hedonic approach abstract this paper is an empirical investigation into factors that are responsible for the differences in prices of classical music compact discs though primarily a statistical exercise the current work has implications for understanding the structure conduct and performance experienced by the classical music record industry the major changes experienced by this industry are highlighted we focus on the rapid technological change in recording technologies format changes the product heterogeneity that results from the simultaneous existence of incumbent and entering models with various technological vintages and the behaviour of firms of different kinds using an as yet untapped french data source for the period 1989 1994 the results of hedonic regressions indicate that new vintages are priced at a premium reflecting higher recording costs owing to contractual arrangements with superstars this premium is even higher for recordings made by majors the price markups enjoyed by major firms have declined over time because of increasing competitive pressure independents and majors exhibit a distinct behaviour as to the location of classical music cd s recordings in quality space the results favour the hypothesis that independents locate their recordings in empty market niches the nominal quality adjusted prices for independent firms cds declined at an annual average rate twice that of the majors

a dynamic model of quality competition with endogenous prices abstract we develop a dynamic model of price and quality competition in order to analyze the effects of competition on quality provision and to which extent an unregulated market is able to provide a socially optimal quality level our model combines a differential game approach with a hotelling spatial competition framework and our analysis applies in particular to industries such as long term care health care child care and education if providers nursing homes hospitals schools nurseries use closed loop decision rules which imply strategic interaction over time we show that although increased competition leads to higher quality in the steady state quality provision is nevertheless lower than under open loop rules and also suboptimally low from a welfare perspective thus our analysis identifies dynamic strategic interaction between competing providers as a potential source of inefficiency in quality provision

the adoption of switchgrass and miscanthus by farmers impact of liquidity constraints and risk preferences lignocellulosic biomass is expected to become a key feedstock for renewable energy production however the potential supply strongly depends on farmers willingness to grow the new perennial energy crops many economic assessments have been led at the farm level all based on the standard net present value approach this paper looks into the effect of farmers liquidity constraints and risk preferences on switchgrass and miscanthus adoption by farmers we study the problem of the land allocation between a traditional cropping system and an innovative one in a static framework using four intertemporal choice models we find that in central france agronomic and economic conditions switchgrass and miscanthus result to be less profitable in terms of annualised net margin than the usual rape wheat barley rotation nevertheless they can be highly competitive as diversification crops when appropriate contracts are offered to farmers despite the additional liquidity they require

on energy consumption and gdp studies a meta analysis of the last two decades abstract the relationship between energy consumption and gdp growth has been intensely examined in multiple frameworks set by various methods and countries this paper is a meta analysis of 51 studies published in the last two decades with worldwide data since 1949 on the relationship between energy consumption and gdp growth the aim is to systemize some of the factors that cause the variation of results in these studies our results yield evidence that the long run elasticity of gdp growth with respect to energy consumption is not independent of the method employed for cointegration the data type and the inclusion of variables such as the price level or capital in the cointegration equation also 1 increase in capital increases the elasticity of gdp with respect to energy consumption by 0 85

exploiting the oil gdp effect to support renewables deployment the empirical evidence from a growing body of academic literature clearly suggests that oil price increases and volatility dampen macroeconomic growth by raising inflation and unemployment and by depressing the value of financial and other assets surprisingly this issue seems to have received little attention from energy policy makers in percentage terms the oil gdp effect is relatively small producing losses in the order of 0 5 of gdp for a 10 oil price increase in absolute terms however even a 10 oil price rise oil has risen at least 50 in the last year alone produces gdp losses that could they have been averted would significantly offset the cost of increased re deployment this paper draws on the empirical oil gdp literature which we summarize to show that i by displacing gas and oil renewable energy investments can help nations avoid costly macroeconomic losses produced by the oil gdp effect and ii that these avoided losses represent a significant external macroeconomic benefit of such investments we show that a 10 increase in re share avoids gdp losses in the range of 29 53 billion in the us and the eu 49 90 billion for oecd these avoided losses offset one fifth of the re investment needs projected by the erec and half the oecd investment projected by a g 8 task force for the us the figures further suggest that each additional kw of renewables on average avoids 250 450 in gdp losses a figure that varies across technologies as a function of annual capacity factors we approximate that the offset is worth 200 kw for wind and solar and 800 kw for geothermal and biomass while we focus only on renewables the gdp offset will apply in some measure to other non fossil technologies including energy efficiency dsm and nuclear the societal valuation of non fossil alternatives must reflect these avoided gdp losses whose benefit is not fully captured by private investors this said we fully recognize that wealth created in this manner does not directly form a pool of public funds that is easily earmarked for renewables support finally the oil gdp relationship has important implications for correctly estimating direct electricity generating cost for conventional and renewable alternatives and for developing more useful energy security and diversity concepts we also address these issues

an economic assessment of potential ethanol production pathways in ireland abstract an economic assessment was conducted on five biomass to ethanol production pathways utilising the feedstock wheat triticale sugarbeet miscanthus and straw the analysis includes the costs and margins for all the stakeholders along the economic chain this analysis reveals that under current market situations in ireland the production of ethanol under the same tax regime as petrol makes it difficult to compete against that fuel with tax breaks however it can compete against petrol on the other hand even under favourable tax breaks it will be difficult for indigenously produced ethanol to compete against cheaper sources of imported ethanol therefore the current transport fuel market has no economic reason to consume indigenously produced ethanol made from the indigenously grown feedstock analysed at a price that reflects all the stakeholders costs to deliver a significant penetration of indigenous ethanol into the market would require some form of compulsory inclusion or else considerable financial supports to feedstock and ethanol producers

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

energy consumption and economic growth the case of oil exporting countries this paper examines the causal relationship between the per capita energy consumption and the per capita gdp in a panel of 11 selected oil exporting countries by using panel unit root tests and panel cointegration analysis the results show a unidirectional strong causality from economic growth to energy consumption for the oil exporting countries the findings have practical policy implications for decision makers in the area of macroeconomic planning in most major oil exporting countries government policies keep domestic prices bellow free market level resulting in high levels of domestic energy consumption the results imply that the energy conservation through reforming energy price policies has no damaging repercussions on economic growth for this group of countries

cointegration and causality between electricity consumption and gdp empirical evidence from malawi abstract the granger causality gc and error correction ecm techniques were applied on 1970 1999 data for malawi to examine cointegration and causality between electricity consumption kwh and respectively overall gdp agricultural gdp agdp and non agricultural gdp ngdp cointegration was established between kwh and respectively gdp and ngdp but not with agdp the gc results detect bi directional causality between kwh and gdp suggesting that kwh and gdp are jointly determined but one way causality running from ngdp to kwh the ecm results detect causality running one way from gdp also from ngdp to kwh suggesting that a permanent rise in gdp may cause a permanent growth in electricity consumption

the causal relationship between electricity consumption and economic growth in the asean countries abstract this paper investigates the causal relationship between electricity consumption and economic growth among the association of south east asian nations asean 4 members namely indonesia malaysia singapore and thailand using modern time series techniques for the period 1971 2002 the results indicate that there is a bi directional causality between electricity consumption and economic growth in malaysia and singapore this means that an increase in electricity consumption directly affects economic growth and that economic growth also stimulates further electricity consumption in the two countries however uni directional causality runs from economic growth to electricity consumption in indonesia and thailand without any feedback effect thus electricity conservation policies can be initiated without deteriorating economic side effects in the two countries

an evolutionary cournot model with limited market knowledge abstract in this paper we analyze a dynamic game of cournot competition with heterogeneous firms choosing between two different adaptive behavioral rules in deciding output strategies the underlying oligopoly structure is standard using a constant return to scale technology n firms produce homogeneous goods which are sold in a market characterized by constant price elasticity in this setup we assume that a fraction of firms employs a quite rough rule of thumb the so called local monopolistic approximation lma whereas the complementary fraction plays best reply br a more demanding strategy in terms of information and computation requirements the model is first considered with exogenously fixed fractions of firms in the two complementary groups then it is generalized by considering an endogenous evolutionary switching process between the two behavioral strategies based on profit driven replicator dynamics the role of the number of firms information costs and inertia or anchoring attitude in production decisions is analyzed as well as the influence in the evolutionary process of random noise in the demand function and memory of past profits global properties of the oligopoly with evolutionary pressure between behavioral rules are discussed with particular regard to cases in which the nash equilibrium is unstable

current and future financial competitiveness of electricity and heat from energy crops a case study from ireland abstract it has been demonstrated that miscanthus and willow energy crop cultivation could be economically competitive with current agricultural land uses at a farm gate biomass price ranging from 70 to 130 t 1 dry matter styles d thorne f jones m b in review energy crops in ireland an economic comparison of willow and miscanthus production with conventional farming systems biomass and bioenergy may 2006 this paper uses the same farm gate prices to calculate the economic competitiveness of energy crop electricity and heat production using a net present value npv approach 20 year period 5 discount rate direct and gasified co firing of willow wood with coal would result in electricity generation 30 or 37 more expensive than coal generation at current coal and co 2 allowance prices and a farm gate biomass cost of 100 t 1 break even co 2 allowance prices are 33 and 37 t 1 respectively however co firing of miscanthus with peat is close to economic competitiveness and would require a co 2 allowance price of 16 t 1 to break even against a current price of 12 t 1 npv analyses indicate that wood heat is significantly cheaper than oil gas or electric heat excluding existing wood boiler installation subsidies discounted annual savings range from 143 compared with gas to 722 compared with electric heating at the domestic scale and from 3454 to 11 222 at the commercial scale inclusion of available subsidies improves the comparative economics of domestic wood heat substantially the economic advantage of wood heat is robust to variation in fuel prices discount rates and heat loads the greatest obstacles to energy crop utilisation include i a reluctance to consider long term economics ii possible competition from cheaper sources of biomass iii the need for a spatially coordinated supply and utilisation network

renewable energy consumption co2 emissions and oil prices in the g7 countries abstract economic and societal issues related to energy security and global warming is placing greater emphasis on the consumption of renewable energy this paper presents and estimates an empirical model of renewable energy consumption for the g7 countries panel cointegration estimates show that in the long term increases in real gdp per capita and co2 per capita are found to be major drivers behind per capita renewable energy consumption these results are robust across two different panel cointegration estimators oil price increases have a smaller although negative impact on renewable energy consumption deviations from equilibrium are driven mostly by the error correction term as opposed to short term shocks short term deviations from the long term equilibrium take anywhere from between 1 3 years france and 7 3 years japan to correct

the need for improved financial reporting of a developing country energy utility abstract some consideration has been given to regulatory and institutional reforms to facilitate sustainable development in electricity usage in papua new guinea but little attention has been paid to bringing about full compliance of financial reporting expectations of the country s main energy utility examining documentary evidence of the audit reports of the auditor general s office of papua new guinea this study considers the financial reporting compliance of png power for the period 2007 2013 and the means by which compliant reporting may be improved the results of the study reveal that the financial statements of png power are late and receive disclaimers of opinion from the auditor general s office which suggest that png power s stakeholders are not receiving accurate and reliable financial information to make informed decisions about sustainable development of electricity usage and planning in papua new guinea the study reveals that it would take little resources to improve png power s reporting which in turn could enhance national energy policy decision making and energy utility accountability

modelling farmer uptake of perennial energy crops in the uk abstract the uk biomass strategy suggests that to reach the technical potential of perennial energy crops such as short rotation coppice src willow and miscanthus by 2020 requires 350 000 hectares of land this represents a more than 20 fold increase on the current 15 546 hectares previous research has identified several barriers to adoption including concerns over security of income from contracts in addition farmers perceive returns from these crops to be lower than for conventional crops this paper uses a farm level linear programming model to investigate theoretical uptake of energy crops at different gross margins under the assumption of a profit maximising decision maker and in the absence of known barriers to adoption the findings suggest that while src willow at current prices remains less competitive returns to miscanthus should have encouraged adoption on a wider scale than at present this highlights the importance of the barriers to adoption recently announced contracts for miscanthus appear to offer a significant premium to farmers in order to encourage them to grow the crops this raises the question of whether a more cost effective approach would be for government to provide guarantees addressing farmers concerns including security of income from the contracts such an approach should encourage adoption at lower gross margins

electricity consumption and economic growth evidence from turkey abstract this study investigates the causal relationship between electricity consumption and real gdp in turkey during the period of 1950 2000 both of the series were found to be a stationary process around a structural break by the zivot and andrews test thus two different methodologies have been employed to test the granger non causality the dolado lutkepohl test using the vars in levels and the standard granger causality test using the detrended data both tests have yielded a strong evidence for unidirectional causality running from the electricity consumption to the income this implies that the supply of electricity is vitally important to meet the growing electricity consumption hence to sustain the economic growth in turkey

rural electrification policy and institutional linkages some of the problems that have besieged rural electrification in most developing countries include inadequate policies weak institutional frameworks and limited financing in the last two decades governments in developing countries have been making various efforts both at the policy level and in financing to facilitate increased levels of rural electrification however the introduction of market based reforms in the power sector in the last decade has affected the institutional and financing arrangements for rural electrification the reforms have also affected the rate of electrification and affordability of electricity there is need therefore to establish the extent to which the reforms have affected access and affordability of electricity in rural areas and to develop appropriate policy and the supporting institutional structures to align rural electrification with reformed power sectors it is cardinal to establish how privatised and commercialised power companies in a reformed power sector could contribute to rural electrification and the role of governments and government agents in facilitating expanded access to electricity in rural areas

hydroelectricity consumption and economic growth nexus evidence from a panel of ten largest hydroelectricity consumers abstract this paper explores the long run and causal relationships between hydroelectricity consumption and economic growth for a panel of the 10 largest hydroelectricity consuming countries over the period 1965 2012 the countries include brazil canada china france india japan norway sweden turkey and the u s a using the bai and perron 2003 9 tests for cointegration the results indicate that real gdp per capita and hydroelectricity consumption per capita appear to be cointegrated around a broken intercept granger causality results from a nonlinear panel smooth transition vector error correction model suggest different results depending on the regimes which we identified based on structural break tests the test identified three breaks at 1988 2000 and 2009 for the pre 1988 period there is evidence of unidirectional causality running from real gdp per capita to hydroelectricity per capita in both the short and long run over the post 1988 period there exists evidence of bidirectional causality between hydroelectricity energy consumption per capita and real gdp per capita in both the short and the long run the results imply the existence of a feedback hypothesis with both hydroelectricity consumption and growth promoting each other in more recent periods as the importance of hydroelectricity as a renewable energy has become more prominent

the influence of a renewable energy feed in tariff on the decision to produce biomass crops in ireland abstract a target of 30 per cent substitution of biomass for peat in the three peat fired power stations from 2015 has been set by the irish government however a knowledge gap exists on the extent to which irish farmers would actually choose to grow these crops an extension of the renewable energy feed in tariff refit scheme to include the co firing of biomass with peat in electricity generation would enable the power stations to enter into power purchase agreements ppas these offer a fixed price to farmers for biomass feedstock the decision to adopt biomass is represented as a constrained problem under certainty with the objective of profit maximisation the results showed that the price offered under a ppa has a large effect on the economic returns from biomass crops the price that the power stations previously estimated they would be able to pay at 46 and 48 per tonne for willow and miscanthus respectively was used as a starting point at this price the number of farmers who would choose to adopt biomass production is insufficient to achieve the national co firing target the target could be achieved at 70 and 65 per tonne for willow and miscanthus respectively

renewable energy consumption and economic growth evidence from a panel of oecd countries abstract this study examines the relationship between renewable energy consumption and economic growth for a panel of twenty oecd countries over the period 1985 2005 within a multivariate framework given the relatively short span of the time series data a panel cointegration and error correction model is employed to infer the causal relationship the heterogeneous panel cointegration test reveals a long run equilibrium relationship between real gdp renewable energy consumption real gross fixed capital formation and the labor force with the respective coefficients positive and statistically significant the granger causality results indicate bidirectional causality between renewable energy consumption and economic growth in both the short and long run

energy consumption in china past trends and future directions abstract in 2003 china s energy consumption amounted to 1678 million tonnes coal equivalent mtce making china the world s second largest consumer behind only the united states china is now also one of the largest oil importers in the world with an economy that is expected to maintain a rate of growth of 7 8 for decades china s role in the world energy market becomes increasingly influential this makes it important to predict china s future demand for energy the objective of this paper is to apply the bayesian vector autoregressive methodology to forecast china s energy consumption and to discuss potential implications the results of this paper suggest that total energy consumption should increase to 2173 mtce in 2010 an annual growth rate of 3 8 which is slightly slower than the average rate in the past decade the slower growth reflects expected slower economic growth and a decline in energy consumption due to structural changes in the chinese economy

electricity consumption and economic growth in india abstract this paper tries to examine the granger causality between electricity consumption per capita and gross domestic product gdp per capita for india using annual data covering the period 1950 51 to 1996 97 phillips perron tests reveal that both the series after logarithmic transformation are non stationary and individually integrated of order one this study finds the absence of long run equilibrium relationship among the variables but there exists unidirectional granger causality running from economic growth to electricity consumption without any feedback effect so electricity conservation policies can be initiated without deteriorating economic side effects

financial development and environmental quality the way forward the present paper re examines the asymmetric impact of financial development on environmental quality in pakistan for the period 1985q1 to 2014q4 a comprehensive index of financial development is generated using bank and stock market based financial development indicators the results show that inefficient use of energy adversely affects the environmental quality this suggests adoption of energy efficient technology at both production and consumption levels these technologies would be helpful to improve environmental quality enhance the productivity in long run and save energy bank based financial development also impedes the environment the government should encourage lenders to ease the funding for energy sector and allocate financial resources for environment friendly businesses rather than wasting them in consumer financing

economic evaluation of short rotation coppice systems for energy from biomass a review abstract since economic profitability is the most important factor for the adoption of short rotation coppice src for energy from biomass our objective was to analyze and summarize published knowledge about the economic evaluation of src of 37 studies 43 reported economic viability of src in comparison to a reference system whereas 19 stated economic disadvantages of src and 38 reported mixed results depending on the underlying assumptions we found a wide variety of underlying assumptions underlying costs process chains and methods used to evaluate src systems of the 37 studies 8 used static approaches of capital budgeting 84 used dynamic approaches and 8 applied approaches in which uncertainties were taken into account due to the long term nature of investment in src and therewith the uncertain development of sensitive assumptions approaches which consider uncertainties were best suited for economic evaluation the profitability of src was found to be most sensitive to the price for biomass and biomass yield but site specific biomass data was lacking despite the wide variation within each cost unit costs for land rent harvesting chipping and establishment consistently made up the largest proportion of overall costs and should therefore be chosen carefully we close with suggestions for improving the economic evaluation of src and enhancing traceability and comparability of calculations

determinants of changes in electricity generation intensity among different power sectors abstract this study analyzes the determinants of changes in electricity generation intensity in china and further uncovers the reasons for the differences between the changes in electricity generation intensity in the thermal and sustainable power sectors by developing a factorial intertemporal nested decomposition technique using the refined laspeyres index we demonstrate the contributions of electricity generation structure electricity generation to consumption ratio production electricity consumption intensity residential electricity consumption intensity and electricity consumption loss intensity effects although the electricity generation intensity of the thermal power sector has been lower than that of the sustainable power sector the latter has declined remarkably and has remained the key sector driving the overall changes in electricity generation intensity meanwhile the effect of electricity consumption intensity is the main factor that reduces electricity generation intensity moreover the impact of production electricity consumption intensity in the thermal power sector exceeds its impact in the sustainable power sector ultimately we find that the differences between the changes in electricity generation intensity in the thermal and sustainable power sectors are mainly due to their differences in production electricity consumption intensity

the influence of perceived uncertainty on entrepreneurial action in emerging renewable energy technology biomass gasification projects in the netherlands emerging renewable energy technologies cannot break through without the involvement of entrepreneurs who dare to take action amidst uncertainty the uncertainties that the entrepreneurs involved perceive will greatly affect their innovation decisions and can prevent them from engaging in innovation projects aimed at developing and implementing emerging renewable energy technologies this article analyzes how perceived uncertainties and motivation influence an entrepreneur s decision to act using empirical data on biomass gasification projects in the netherlands our empirical results show that technological political and resource uncertainty are the most dominant sources of perceived uncertainty influencing entrepreneurial decision making by performing a dynamic analysis we furthermore demonstrate that perceived uncertainties and motivation are not stable but evolve over time we identify critical factors in the project s internal and external environment which influence these changes in perceived uncertainties and motivation and describe how various interactions between the different variables in the conceptual model internal and external factors perceived uncertainty motivation and previous actions of the entrepreneurs positively or negatively influence the decision of entrepreneurs to continue entrepreneurial action we discuss how policymakers can use these insights for stimulating the development and diffusion of emerging renewable energy technologies

energy consumption and economic growth in the usa evidence from renewable energy abstract recent debates about renewable energy consumption manifest two main expectations firstly renewable energy consumption should contribute to economic growth and secondly it should not cause damage on environment this study focuses on the first issue by applying toda yamamoto procedure and bootstrap corrected causality test for the us since empirical literature criticizes the toda yamamoto test which bases on asymptotic distribution the models consist of real gdp employment investment and kinds of renewable energy consumption only one causal relationship was found from biomass waste derived energy consumption to real gdp no causal relationship was found between real gdp and all of the other renewable energy kinds total renewable energy consumption geothermal energy consumption hydro electric energy consumption biomass energy consumption and biomass wood derived energy consumption that is using of energy from waste cause not only solving the dumping problems but also it contributes to real gdp for policy purpose the results of this study suggest that countries should concentrate on energy producing from waste as an alternative energy resource

endogenous fluctuations under evolutionary pressure in cournot competition abstract an evolutionary game theoretic model of cournot competition is investigated individuals choose from a finite set of different behavioral rules each rule specifies the quantity to be produced in the current period as a function of past quantities using more sophisticated rules may require extra information costs based upon realized payoffs the fractions of the population choosing a certain behavioral rule are updated according to the replicator equation with noise the long run behavior of the evolutionary system consisting of the population dynamics coupled with the quantity dynamics of the cournot game may be complicated and endogenous fluctuations may arise we consider a typical example where firms can choose between two rules the nash rule and the best reply rule we show that a homoclinic tangency between the stable and unstable manifold of the equilibrium occurs as evolutionary pressure increases implying bifurcation routes to complicated dynamics and strange attractors

energy and economic analysis for large scale integration of small photovoltaic systems in buildings the case of a public location in southern spain abstract the integration of grid connected pv systems into buildings or public areas is one of the most usual applications of the photovoltaic solar energy in developed countries and it is being highly promoted by several european governments in this paper it has been evaluated the photovoltaic potential of the campus of the university of jaen and it has been defined possible areas where the pv systems could be installed according to power requirements space possibilities the electrical configuration of the campus and some social integration requirements too the definition of the pv potential together with a technical analysis for the calculation of the energy generated is the previous step for carrying out an economic and cost analysis in order to certify the profitability of these systems in general particularizing the study for the case of this university located in southern spain the pv electricity cost generated has been calculated through the concept levelised cost of electricity lcoe where in our case is estimated to be around 0 13 0 14 kwh 1 the results obtained in this economic analysis recommend the implementation of pv grid connected systems pvgcs as the internal rate of return reaches a maximum value of 6 21 the net present value is positive and the discounted payback time is around 16 years an additional sensitive analysis shows the influence that some parameters have on the lcoe specially the initial investment the energy yield and the nominal discount rate

the willingness of farmers to engage with bioenergy and woody biomass production a regional case study from cumbria abstract in this paper we explore the willingness of cumbrian farmers to switch land use from food production to biomass production in a landscape where food production is both heavily subsidised and the area is a centre for tourism this is against a policy background of a switch of subsidies from food production to environmental benefits increased concerns about emissions from farming and an increased demand for renewable energy we identified an awareness of new markets for renewable energy alongside increasing volatility of other crops against a background of increasing demand for food from this our conclusions are that the main short term opportunities for increasing biomass production in this region are through intensifying management of existing woodlands in the medium term as the financial case for biomass crops becomes more certain we can envisage a tipping point which would favour a switch from marginal agricultural land to biomass

economic analysis of pv systems on buildings in sicilian farms abstract the photovoltaic sector in italy in recent years has experienced a rapid growth also in the primary sector thanks to substantial incentives guaranteed by energy policies simultaneous reduction of investment costs and tax benefits in order to better understand the growth of the pv industry in italian primary sector the aim of this paper has been to evaluate the economic convenience of four pv systems on farm buildings located in four different farms of the north western coast of sicily and realized during the second and fourth italian feed in schemes for each feed in scheme it has been considered a pv plant that sells the electricity to the grid and another in which the energy generated is consumed entirely by the farm the results show a clear convenience to the realization of investments both with the current market conditions and at the variation of the feed in tariff or the investment costs

equilibrium selection in a nonlinear duopoly game with adaptive expectations abstract we analyze a nonlinear discrete time cournot duopoly game where players have adaptive expectations the evolution of expected outputs over time is generated by the iteration of a noninvertible two dimensional map the long run behavior is characterized by multistability that is the presence of coexisting stable consistent beliefs which correspond to nash equilibria in the quantity space hence a problem of equilibrium selection arises and the long run outcome strongly depends on the choice of the players initial beliefs we analyze the basins of attraction and their qualitative changes as the model parameters vary we illustrate that the basins might be nonconnected sets and reveal the mechanism which is responsible for this often neglected kind of complexity the analysis of the global bifurcations which cause qualitative changes in the topological structure of the basins is carried out by the method of critical curves

energy consumption and economic growth evidence from china at both aggregated and disaggregated levels using a neo classical aggregate production model where capital labor and energy are treated as separate inputs this paper tests for the existence and direction of causality between output growth and energy use in china at both aggregated total energy and disaggregated levels as coal oil and electricity consumption using the johansen cointegration technique the empirical findings indicate that there exists long run cointegration among output labor capital and energy use in china at both aggregated and all three disaggregated levels then using a vec specification the short run dynamics of the interested variables are tested indicating that there exists granger causality running from electricity and oil consumption to gdp but does not exist granger causality running from coal and total energy consumption to gdp on the other hand short run granger causality exists from gdp to total energy coal and oil consumption but does not exist from gdp to electricity consumption we thus propose policy suggestions to solve the energy and sustainable development dilemma in china as enhancing energy supply security and guaranteeing energy supply especially in the short run to provide adequate electric power supply and set up national strategic oil reserve enhancing energy efficiency to save energy diversifying energy sources energetically exploiting renewable energy and drawing out corresponding policies and measures and finally in the long run transforming development pattern and cut reliance on resource and energy dependent industries

renewable energy consumption and growth in eurasia this study examines the causal relationship between renewable energy consumption and economic growth for 13 countries within eurasia over the period 1992 2007 within a multivariate panel data framework the heterogeneous panel cointegration test reveals a long run equilibrium relationship exists between real gdp renewable energy consumption real gross fixed capital formation and labor force the results from the error correction models indicate bidirectional causality between renewable energy consumption and economic growth in both the short run and long run thus the empirical findings lend support for the feedback hypothesis of the interdependent relationship between renewable energy consumption and economic growth

economic evaluation of miscanthus production a review this paper reviews the peer reviewed literature dealing with the economics of miscanthus cultivation to identify factors influencing the adoption of miscanthus and to reveal shortcomings in research in total 51 studies have been identified for this review the majority of these publications are recent i e the majority is published after 2009 and concern case studies in europe particularly the uk and ireland and north america this review reveals that the economic viability of miscanthus depends on largely uncertain assumptions especially concerning yields 10 48 t dry matter per ha and prices 48 134 t dry matter but also concerning the lifespan 10 20 years and different cost items a lack of established markets high establishment costs and uncertainties arising to a large extent from the long term commitment are identified as major barriers to miscanthus adoption in addition the level of support for miscanthus production e g via subsidies is identified as crucial for miscanthus profitability but is found to be highly heterogeneous across countries next to diversity in agronomic and economic assumptions also the assessment criteria and research techniques used to investigate the profitability of miscanthus differ widely while the net present value criterion was most frequently used we identify a lack of approaches that account for risks and uncertainties which seem to potentially play a critical role in the uptake of miscanthus by farmers

a literature survey on energy growth nexus abstract this paper provides a survey of the recent progress in the literature of energy consumption economic growth and electricity consumption economic growth causality nexus the survey highlights that most empirical studies focus on either testing the role of energy electricity in stimulating economic growth or examining the direction of causality between these two variables although the positive role of energy on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies a general observation from these studies is that the literature produced conflicting results and there is no consensus neither on the existence nor on the direction of causality between energy consumption electricity consumption and economic growth as a policy implication to avoid from conflicting and unreliable results the authors may use the autoregressive distributed lags bounds test two regime threshold co integration models panel data approach and multivariate models including new variables such as real gross fixed capital formation labor force carbon dioxide emissions population exchange rates interest rates etc thus the authors should focus more on the new approaches and perspectives rather than by employing usual methods based on a set of common variables for different countries and different intervals of time
