the effect of urbanization affluence and trade openness on energy consumption a time series analysis in malaysia abstract this paper investigates the impact of urbanization on energy consumption by applying the stochastic impacts by regression on population affluence and technology stirpat in case of malaysia the study covers the time period of 1970q1 2011q4 the unit root test and the ardl bounds testing approach have been applied to examine integrating properties and long run relationship in the presence of structural breaks our results validated the existence of cointegration and exposed that urbanization is a major contributor in energy consumption affluence raises energy demand capital stock boosts energy consumption trade openness leads to affluence and hence increases energy consumption the causality analysis finds that urbanization granger causes energy consumption the feedback effect is found between energy consumption and affluence and energy consumption and capital the bidirectional causality exists between trade openness and energy consumption

the inherent inefficiency of simultaneously feasible financial transmission rights auctions abstract empirical evidence from the new york iso shows that the clearing prices for point to point congestion revenue rights also known as financial transmission rights ftrs resulting from centralized auctions conducted by independent system operators differ significantly and systematically from the realized congestion revenues that determine the accrued payoffs of these rights the question addressed by this paper is whether such deviations are due to price discovery errors which will eventually vanish or due to inherent inefficiencies in the auction structure we show that even with perfect foresight of average congestion rents the clearing prices for the ftrs depend on the bid quantity and therefore may not be priced correctly in the financial transmission right ftr auction in particular we prove that quantity limits on the ftr bids may cause the auction clearing prices to differ from the bid prices this phenomenon which is inherent in the theoretical properties of the optimization algorithm used to clear the auction is further illustrated through numerical simulations with test systems we conclude that price discovery alone would not remedy the discrepancy between the auction prices and the realized values of the ftrs secondary markets or frequent reconfiguration auctions are necessary in order to achieve such convergence

stochastic modeling of financial electricity contracts abstract we discuss the modeling of electricity contracts traded in many deregulated power markets these forward futures type contracts deliver either physically or financially electricity over a specified time period and is frequently referred to as swaps since they in effect represent an exchange of fixed for floating electricity price we propose to use the heath jarrow morton approach to model swap prices since the notion of a spot price is not easily defined in these markets for general stochastic dynamical models we connect the spot price the instantaneous delivery forward price and the swap price and analyze two different ways to apply the heath jarrow morton approach to swap pricing either one specifies a dynamics for the non existing instantaneous delivery forwards and derives the implied swap dynamics or one models directly on the swaps the former is shown to lead to quite complicated stochastic models for the swap price even when the forward dynamics is simple the latter has some theoretical problems due to a no arbitrage condition that has to be satisfied for swaps with overlapping delivery periods to overcome this problem a practical modeling approach is analyzed the market is supposed only to consist of non overlapping swaps and these are modelled directly a thorough empirical study is performed using data collected from nord pool our investigations demonstrate that it is possible to state reasonable models for the swap price dynamics which is analytically tractable for risk management and option pricing purposes however this is an area of further research

forecasting hourly electricity prices using armax garch models an application to miso hubs abstract the recent deregulation of the electricity industry and reliance on competitive wholesale markets has generated significant volatility in wholesale electricity prices given the importance of short term price forecasts in this new environment this paper estimates and evaluates the forecasting performance of four armax garch models for five miso pricing hubs cinergy first energy illinois michigan and minnesota using hourly data from june 1 2006 to october 6 2007 our empirical results reveal three important patterns a electricity price volatility is regional and the optimum volatility model depends in part on the hub location the forecast horizon and regulated versus unregulated status of the market b the aparch model performs well in hubs in deregulated states and c volatility dynamics in regulated states are better captured by a simple garch model and thus are less complex

the effect of urbanization on energy use in india and china in the ipets model abstract urbanization is one of the major demographic and economic trends occurring in developing countries with important consequences for development energy use and well being yet it is only beginning to be explicitly incorporated in long term scenario analyses of energy and emissions we assess the implications of a plausible range of urbanization pathways for energy use and carbon emissions in india and china using the integrated population economy technology science ipets model a computable general equilibrium cge model of the global economy that captures heterogeneity in household types within world regions and into which we have introduced income effects on household consumption preferences we find that changes in urbanization have a somewhat less than proportional effect on aggregate emissions and energy use a decomposition analysis demonstrates that this effect is due primarily to an economic growth effect driven by the increased labor supply associated with faster urbanization the influence of income on household consumption is strong and indicates a potentially rapid transition away from traditional fuel use and toward modern fuels such as electricity and natural gas results also indicate important directions for future work including the implications of alternative types and driving forces of urbanization over time a better understanding of possible changes in consumption preferences associated with income growth and the urbanization process and modeling strategies that can produce disaggregated household consumption outcomes within a cge framework

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

industrialization electricity consumption and co2 emissions in bangladesh this paper investigates the relationship between industrialization electricity consumption and co2 emissions in case of bangladesh using quarter frequency data over the period of 1975 2010 the ar

the economic consequences of partisanship in a polarized era with growing affective polarization in the united states partisanship is increasingly an impediment to cooperation in political settings but does partisanship also affect behavior in nonpolitical settings we show evidence that it does demonstrating its effect on economic outcomes across a range of experiments in real world environments a field experiment in an online labor market indicates that workers request systematically lower reservation wages when the employer shares their political stance reflecting a preference to work for co partisans we conduct two field experiments with consumers and find a preference for dealing with co partisans especially among those with strong partisan attachments finally via a population based incentivized survey experiment we find that the influence of political considerations on economic choices extends also to weaker partisans whereas earlier studies show the political consequences of polarization in american politics our findings suggest that partisanship spills over beyond the political shaping cooperation in everyday economic behavior

alternative regulatory methods and firm efficiency stochastic frontier evidence from the u s electricity industry the use of incentive regulation and other alternative regulatory programs in u s electricity markets has grown during the past two decades within a stochastic frontier framework i investigate the effect of individual programs on the technical efficiency of a large set of coal and natural gas generation units i find that those programs tied directly to generator performance and those that modify traditional fuel cost pass through programs to provide a greater incentive to reduce fuel costs are associated with greater efficiency levels other programs have no statistical association with efficiency levels

energy consumption and economic growth evidence from 11 sub sahara african countries abstract the paper examines the causal relationship between energy consumption and economic growth for eleven countries in sub saharan africa using the autoregressive distributed lag ardl bounds test the study finds that energy consumption is cointegrated with economic growth in cameroon cote d ivoire gambia ghana senegal sudan and zimbabwe moreover this test suggests that energy consumption has a significant positive long run impact on economic growth in ghana kenya senegal and sudan granger causality test based on vector error correction model vecm shows bi directional relationship between energy consumption and economic growth for gambia ghana and senegal however granger causality test shows that economic growth granger causes energy consumption in sudan and zimbabwe the neutrality hypothesis is confirmed in respect of cameroon and cote d ivoire the same result of no causality was found for nigeria kenya and togo the result shows that each country should formulate appropriate energy conservation policies taking into cognizance of her peculiar condition

energy consumption and gdp causality relationship in g 7 countries and emerging markets abstract the causality relationship between energy consumption and income is a well studied topic in energy economics this paper studies the time series properties of energy consumption and gdp and reexamines the causality relationship between the two series in the top 10 emerging markets excluding china due to lack of data and g 7 countries we discover bi directional causality in argentina causality running from gdp to energy consumption in italy and korea and from energy consumption to gdp in turkey france germany and japan hence energy conservation may harm economic growth in the last four countries

greenhouse gas emission and renewable energy sources for sustainable development in bangladesh abstract bangladesh is an energy starving country the country will be on one of the fast growing power markets with its population and growing energy demand per person its fast growing urbanization and its socio economic development at present the potential demand of power is 5569 mw and the supply is below 4000 mw the country is dependent on the imported petroleum that is big burden on the economy the per capita emission is only 0 2667 tonne per person still much below the world leading countries 19 8 tonne per person for usa however bangladesh is one of the most vulnerable to climate change effect in the world in this regard renewable energy resources appear to be the one of the most efficient and effective solution for clean and sustainable energy development in bangladesh biomass is the dominating source of energy in bangladesh biomass energy is used in a very traditional way biomass conversion to energy in the form of liquid gaseous and solid pellet or briquette could be a viable option to reduce the pressure on the conventional fossil fuel the geographical location of bangladesh has several advantages for extensive use of grid connected solar electricity and stand alone solar pv system this article presents a review of the potential and utilization of the renewable energy sources in bangladesh

does financial development increase energy consumption the role of industrialization and urbanization in tunisia this paper assesses the relationship among energy consumption financial development economic growth industrialization and urbanization in tunisia from 1971 to 2008 the autoregressive distributed lag bounds testing approach to cointegration and granger causality tests is employed for the analysis the result confirms the existence of long run relationship among energy consumption economic growth financial development industrialization and urbanization in tunisia long run bidirectional causalities are found between financial development and energy consumption financial development and industrialization and industrialization and energy consumption hence sound and developed financial system that can attract investors boost the stock market and improve the efficiency of economic activities should be encouraged in the country nevertheless promoting industrialization and urbanization can never be left out from the process of development we add light to policy makers with the role of financial development industrialization and urbanization in the process of economic development

cointegration analysis of spot electricity prices insights on transmission efficiency in the western us abstract the us energy policy act of 1992 promoted the development of spot markets for electric power by requiring utilities to open their transmission systems to wholesale power sales in this paper we specify and estimate a vector error correction model using peak and off peak electricity spot prices during 1994 1996 covering 11 regional markets in the western united states and test these prices for evidence of market integration the results show evidence of an efficient and stable wholesale power market

speculation in the oil market the run up in oil prices since 2004 coincided with growing investment in commodity markets and increased price co movement among different commodities we assess whether speculation in the oil market played a role in driving this salient empirical pattern we identify oil shocks from a large dataset using a dynamic factor model this method is motivated by the fact that a small scale vector autoregression is not informationally sufficient to identify the shocks the main results are as follows i while global demand shocks account for the largest share of oil price fluctuations speculative shocks are the second most important driver ii the increase in oil prices over the last decade is mainly driven by the strength of global demand however speculation played a significant role in the oil price increase between 2004 and 2008 and its subsequent collapse iii the co movement between oil prices and the prices of other commodities is mainly explained by global demand shocks our results support the view that the recent oil price increase is mainly driven by the strength of global demand but that the financialization process of commodity markets also played a role

socioeconomic development and electricity consumption a cross country analysis using the random coefficient method this paper analyses the relationship between electricity consumption and socioeconomic variables by estimating the electricity consumption function on the basis of single year cross country data and using ols and random coefficient rc methods the latter method yields both mean response as well as country specific coefficients while electricity consumption is found to rise with socioeconomic development it is found to be inelastic with respect to changes in all the variables the estimated country specific coefficients with respect to per capita gnp and share of industry in gdp are found not to vary across countries indicating that the impact of these variables on electricity consumption is similar across countries on the other hand the impact of other variables years of schooling gdp growth urbanization and population density is found to vary substantially across countries

efficiency of financial transmission rights markets in centrally coordinated periodic auctions electricity market design in the united states is increasingly dominated by locational marginal pricing lmp of energy and transmission lmp markets are typically coupled with periodic auctions of financial transmission rights ftrs to hedge transmission price risks while lmp designs offer considerable advantages forward price discovery in these markets requires participants to form efficient expectations on spot congestion price differences in this paper we examine trends in the efficiency of one of the early lmp markets the new york independent system operator nyiso analyzing a panel data set of over 9000 contracts over a six year period beginning september 2000 we show that nyiso ftr markets were inefficient in their early years but that market participants learned to predict forward prices and thus efficiency improved for ftrs not solely within the new york city long island sub region ftrs within this sub region which has a number of special characteristics remain relatively inefficient

limits to arbitrage in electricity markets a case study of miso abstract we study the case of financial traders in the midwest electricity market where they are expected to arbitrage price differences that result in inefficiencies using exogenous variation in financial trading from the financial crisis and a period of high transaction costs we show speculators had only a weak effect moreover while arbitrage was restricted by transaction costs imposed by regulation some financial players bet in exactly the opposite direction of the pricing gap sustaining large losses while doing so we show this is consistent with price manipulation intended to increase the value of a related instrument that bets on local price differences ftrs

the relation between chinese economic development and energy consumption in the different periods since the 1980s chinese economy grew rapidly with the rapid economic growth chinese energy consumption sharply increased the relation between chinese energy consumption and economic growth is focused on and many researchers have studied this issue by applying the methods such as granger causality test however the results just reveal the relation in a very long period in this paper the history of chinese economy is divided into four periods and the relation between chinese energy consumption and economic growth is examined by applying grey incidence analysis which is one of the most important methods of grey system theory which can be applied to solve the problems with small samples the results show that the relations in different periods are not the same the degree of grey incidences between total energy consumption and values added of secondary industry is larger and the degree of grey incidences between gdp and consumption of coal is larger too and the policy implications of these results are explained

examining the link between carbon dioxide emissions and the share of industry in gdp modeling and testing for the g 7 countries abstract in this paper the relationship between per capita co 2 emissions and the share of industrial value added in gross domestic product gdp for the g 7 countries is discussed using a novel approach it is assumed that per capita co 2 emissions are correspondent to the share of industrial value added in gdp a model is developed using hidden markov process to search this initial assumption in the model the data for industrial share in gdp are assigned to be the observations while the data for per capita co 2 emissions represent the hidden process which may be then predicted using the ratio of industrial value added to gdp the data set covers the period from 1970 to 2008 and the model is tested for the g 7 countries the study findings show that except in the case of canada the hidden markov model performs reasonably well in tracking per capita co 2 emissions the study results provide also a basis for a number of policy implications

iso net surplus collection and allocation in wholesale power markets under lmp this study uses five bus and 30 bus test cases to explore iso net surplus congestion rent collections and allocations in wholesale power markets with grid congestion managed by locational marginal prices lmps price sensitivity of demand and generator learning capabilities are taken as experimental treatment factors a key finding is that conditions resulting in greater generator capacity withholding hence higher and more volatile lmps also result in greater iso net surplus collections that can be substantial in size a key conclusion is that iso net surplus collections should be used pro actively to mitigate the conditions encouraging generator capacity withholding and hence high and volatile lmps rather than to provide ex post support for lmp payment offsets and lmp volatility risk hedging as is currently the norm

non renewable and renewable energy consumption and co2 emissions in oecd countries a comparative analysis abstract this paper attempts to explore the determinants of co 2 emissions using the stirpat model and data from 1980 to 2011 for oecd countries the empirical results show that non renewable energy consumption increases co 2 emissions whereas renewable energy consumption decreases co 2 emissions further the results support the existence of an environmental kuznets curve between urbanisation and co 2 emissions implying that at higher levels of urbanisation the environmental impact decreases therefore the overall evidence suggests that policy makers should focus on urban planning as well as clean energy development to make substantial contributions to both reducing non renewable energy use and mitigating climate change

co2 emissions energy consumption trade and income a comparative analysis of china and india in order to prevent the destabilisation of the earth s biosphere co2 emissions must be reduced quickly and significantly the causes of co2 emissions by individual countries need to be apprehended in order to understand the processes required for reducing emissions around the globe china and india are the two largest transitional countries and growing economies but are in two entirely different categories in terms of structural changes in growth trade and energy use co2 emissions from the burning of fossil fuels have significantly increased in the recent past this paper compares china and india using the bounds testing approach to cointegration and the ardl methodology to test the long and short run relationships between growth trade energy use and endogenously determined structural breaks the co2 emissions in china were influenced by per capita income structural changes and energy consumption a similar causal connection cannot be established for india with regard to structural changes and co2 emissions because india s informal economy is much larger than china s india possesses an extraordinarily large number of micro enterprises that are low energy consumers and not competitive enough to reach international markets understanding these contrasting scenarios is prerequisite to reaching an international agreement on climate change affecting these two countries

effects of urbanisation on energy consumption in china as a key issue in china s economic development urbanisation creates increasing pressure on energy supply and the natural environment thus a better understanding of the relationship between urbanisation and energy consumption is necessary for chinese decision makers at various levels to address energy security and sustainable economic and social development this paper empirically investigates the effects of china s urbanisation on residential energy consumption rec and production energy consumption pec through a time series analysis the results show that compared with rural areas urbanisation slows per capita rec growth because of the economy of scale and technological advantages associated with urbanisation but has greater promotional effects on the growth of rec and the improvement of rec structure the economic growth caused by urbanisation most significantly contributes to an increase in pec whereas technological advancement was found to reduce the scale of pec except from 2001 to 2005 finally the structural effect of the energy supply increased rather than decreased china s pec and the effect of industrial structure adjustment on pec was found to be insignificant

the energy growth nexus in thailand does trade openness boost up energy consumption the nexus between trade openness and energy demand is hot topic of discussion among academicians and researchers and numerous studies are available in existing literature while investigating the nexus between trade openness and energy demand this paper explores the relationship between energy consumption trade openness and economic growth in case of thailand in doing so we have applied bayer and hanck cointegration approach to test whether the long run relationship exists between the variables our results confirm the presence of cointegration between the variables energy consumption stimulates economic growth trade openness adds in economic growth the causality analysis reveals that energy consumption granger causes economic growth and in resulting economic growth granger causes energy consumption trade openness and energy consumption are interdependent i e trade openness granger causes energy consumption and in return energy consumption granger causes trade openness this paper openness up new directions for policy making authorities in thailand to design a comprehensive energy and trade policies to sustain economic growth for long run

trade and consumption of energy varieties empirical analysis of selected west africa economies abstract this paper examined the relationship between consumption of energy varieties total electricity and road transport and trade export and import in selected west african countries data spanning 1971 to 2010 was used to estimate vector error correction models vecm for 6 countries based on data availability empirical analysis showed that there is insignificant linkage between consumption of energy varieties and export of benin however there is a one way positive linkage running from energy varieties to import of the country for cote d ivoire energy varieties have insignificant relationship with export and import however while inverse relationship runs from export to both electricity and road transport energy consumption positive direct association runs from import to total energy and transport energy consumption with respect to ghana positive causality runs from electricity and road transport energy consumption to export however there is a significant positive feedback effect between import and electricity as well as road transport energy consumption for nigeria there is a significant positive link running from both electricity and road transport energy consumption to export and import senegal s case suggests a bi directional inverse linkage between export and total energy consumption for togo both export and import are insignificantly linked with energy use these mixed findings generate different policy implications across the selected west african countries which are well articulated in the paper

a further inquiry into ftr properties abstract william hogan introduced financial transmission rights as a tool to hedge the locational risk inherent in locational marginal prices ftrs are claimed to serve four main purposes 1 provide a hedge for nodal price differences 2 provide revenue sufficiency for contracts for differences 3 distribute the merchandizing surplus an rto accrues in market operations and 4 provide a price signal for transmission and generation developers this paper examines the hedging and redistributional properties of ftrs it argues that ftr allocation has important distributional impacts and related implications for retail rates this observation adds an additional explanation for rate increases in light of decreased production costs due to restructuring this paper also shows that rto practices have important implications for the hedging characteristics of ftrs it further shows via counterexample that even in theory ftrs may not serve as a perfect hedge against congestion charges the paper concludes with a series of recommendations for ftr allocation and the functions that ftrs should serve

china s energy demand and its characteristics in the industrialization and urbanization process a reply zhang and qin 2013 argued that in jiang and lin 2012 the equation form and variable selection should be altered and it was problematic to use regression equation to project the future in this reply we disagree with and will refute some of the points raised in their comments the model that we established was based on the mature economic theory with the variable selections all having economic implications considering the economic development stage china s urbanization will speed up and this will have significant effect on energy consumption therefore urbanization is an indispensable variable for analyzing energy demand in china the scenario design only in terms of the gdp is sufficient for illustrating energy demand trend in china to be understood in a way by most of the people although energy forecast is not that precise it has an important implication for energy policy design especially for china which is in transition and china s energy demand will keep high growth in the mid term

impacts of urbanization and industrialization on energy consumption co2 emissions does the level of development matter urbanization and industrialization have significant impacts on energy consumption and co2 emissions but their relationship varies at different stages of economic development taking cognizance of heterogeneity and the ratchet effect this paper adopts the stochastic impacts by regression on population affluence and technology stirpat framework as a starting point and re estimates the relationship using different panel date models the main results are obtained by dynamic panel threshold regression models which divide a balanced panel dataset of 73 countries over the period of 1971 2010 into four groups according to their annual income levels the key results are 1 in the low income group urbanization decreases energy consumption but increases co2 emissions 2 in the middle low income and high income groups industrialization decreases energy consumption but increases co2 emissions while urbanization significantly increases both energy consumption and co2 emissions 3 for the middle high income group urbanization does not significantly affect energy consumption but does hinder the growth of emissions while industrialization was found to have an insignificant impact on energy consumption and co2 emissions 4 from the population perspective it produces positive effects on energy consumption and also increases emissions except for the high income group these novel methodology and findings reveal that different development strategies of urbanization and industrialization should be pursued depending on the levels of income in a bid to conserve energy and reduce emissions

how internal constraints shape interest group activities evidence from access seeking pacs interest groups contribute much less to campaigns than legally allowed consequently prevailing theories infer these contributions must yield minimal returns i argue constraints on pac fundraising may also explain why interest groups give little i illuminate one such constraint access seeking pacs rely on voluntary donations from affiliated individuals e g employees and these pacs alienate donors with partisan preferences when giving to the opposite party first difference in differences analysis of real giving shows donors withhold donations to access seeking pacs when pacs contribute to out partisan politicians next an original survey of corporate pac donors demonstrates they know how their pacs allocate contributions across parties and replicates the observational study in an experiment donors partisanship thus limits access seeking pacs fundraising and influence this provides a new perspective on why there is little interest group money in elections and has broad implications for how partisan preferences and other internal constraints shape interest group strategy

energy consumption and gdp in tunisia cointegration and causality analysis abstract in this paper the johansen cointegration technique is used to examine the causal relationship between per capita energy consumption pcec and per capita gross domestic product pcgdp for tunisia during the 1971 2004 period in order to test for granger causality in the presence of cointegration among the variables a vector error correction model vecm is used instead of a vector autoregressive var model our estimation results indicate that the pcgdp and pcec for tunisia are related by one cointegrating vector and that there is a long run bi directional causal relationship between the two series and a short run unidirectional causality from energy to gross domestic product gdp the source of causation in the long run is found to be the error correction terms in both directions hence an important policy implication resulting from this analysis is that energy can be considered as a limiting factor to gdp growth in tunisia conclusions for tunisia may also be relevant for a number of countries that have to go through a similar development path of increasing pressure on already scarce energy resources

urban and rural energy use and carbon dioxide emissions in asia the process of urbanization has been shown to be important for economic development environmental impacts and human wellbeing particularly in developing countries in this paper we compare structure data sources and scenario results of four integrated assessment models that are capable of analyzing different aspects of urbanization the comparison focuses on residential sector energy use and related co2 emissions based on a set of urbanization scenarios for china and india important insights from this model comparison include that i total fossil fuel and industrial co2 emissions at the regional level are not very sensitive to alternative rates of urbanization and are largely dependent on the linkage between urbanization and economic growth via differentiated labor productivity in urban and rural areas ii alternative urbanization pathways may yield different results for the share of solid fuels in residential energy use thereby affecting the number of people relying on these fuels and the associated adverse health impacts and iii alternative economic growth scenarios can only be assessed for their welfare implications if urban and rural household are distinguished even though that distinction does not always strongly affect aggregate outcomes which is often due to two effects that compensate each other in total it can be concluded that urbanization and heterogeneity of households and consumers are clearly relevant for distributional effects and associated health and social impacts

does urbanization lead to less energy use and lower co2 emissions a cross country analysis despite the relationship between urbanization energy use and co2 emissions has been extensively studied in recent years little attention has been paid to differences in development stages or income levels most previous studies have implicitly assumed that the impact of urbanization is homogenous for all countries this assumption can be questionable as there are many characteristic differences among countries of different levels of affluence this paper investigates empirically the effects of urbanization on energy use and co2 emissions with consideration of the different development stages using the stochastic impacts by regression on population affluence and technology stirpat model and a balanced panel dataset of 99 countries over the period 1975 2005 the findings suggest that the impact of urbanization on energy use and emissions varies across the stages of development surprisingly urbanization decreases energy use in the low income group while it increases energy use in the middle and high income groups the impact of urbanization on emissions is positive for all the income groups but it is more pronounced in the middle income group than in the other income groups these novel findings not only help advance the existing literature but also can be of special interest to policy makers and urban planners

panel estimation for co2 emissions energy consumption economic growth trade openness and urbanization of newly industrialized countries abstract this paper empirically examines the dynamic causal relationships between carbon dioxide emissions energy consumption economic growth trade openness and urbanization for the panel of newly industrialized countries nic using the time series data for the period 1971 2007 using four different panel unit root tests it is found that all panel variables are integrated of order 1 from the johansen fisher panel cointegration test it is found that there is a cointegration vector among the variables the granger causality test results support that there is no evidence of long run causal relationship but there is unidirectional short run causal relationship from economic growth and trade openness to carbon dioxide emissions from economic growth to energy consumption from trade openness to economic growth from urbanization to economic growth and from trade openness to urbanization it is found that the long run elasticity of carbon dioxide emissions with respect to energy consumption 1 2189 is higher than short run elasticity of 0 5984 this indicates that over time higher energy consumption in the newly industrialized countries gives rise to more carbon dioxide emissions as a result our environment will be polluted more but in respect of economic growth trade openness and urbanization the environmental quality is found to be normal good in the long run

the causality between energy consumption and economic growth in turkey abstract this paper applies the causality test to examine the causal relationship between primary energy consumption ec and real gross national product gnp for turkey during 1970 2006 we employ unit root tests the augmented dickey fuller adf and the philips perron pp johansen cointegration test and pair wise granger causality test to examine relation between ec and gnp our empirical results indicate that the two series are found to be non stationary however first differences of these series lead to stationarity further the results indicate that ec and gnp are cointegrated and there is bidirectional causality running from ec to gnp and vice versa this means that an increase in ec directly affects economic growth and that economic growth also stimulates further ec this bidirectional causality relationship between ec and gnp determined for turkey at 1970 2006 period is in accordance with the ones in literature reported for similar countries consequently we conclude that energy is a limiting factor to economic growth in turkey and hence shocks to energy supply will have a negative impact on economic growth

causality between energy consumption and economic growth in india a note on conflicting results abstract this note examines the different direction of causal relation between energy consumption and economic growth in india applying engle granger cointegration approach combined with the standard granger causality test on indian data for the period 1950 1996 we find that bi directional causality exists between energy consumption and economic growth further we apply johansen multivariate cointegration technique on the different set of variables the same direction of causality exists between energy consumption and economic growth this is different from the results obtained in earlier studies

valuation of physical transmission rights an analysis of electricity cross border capacities between germany and the netherlands abstract the purpose of this paper is to discuss market coherent valuation of physical transmission rights for cross border capacities between germany and the netherlands aiming at a fair valuation of these contracts the most important stylized facts of electricity prices such as mean reversion spikes and correlations of regional prices have to be considered we present different approaches to the valuation of physical transmission rights and perform a quantitative analysis of the results on the one hand various challenges of modeling regional price spreads are analyzed on the other hand we indicate a structural undervaluation of physical transmission rights in all model constellations i e market prices are below theoretical prices of ptr s flexibility we discuss several reasons for this undervaluation and finally state that regulatory modifications have to be made to avoid missing incentives for the extension of cross border capacities

the impact of energy consumption and co2 emission on the economic and financial development in 19 selected countries abstract this study investigated the impact of energy consumption on the economic and financial development in 19 countries these countries were selected due to the fact that the financial development indicators contribute an important share to their total gdp the panel model was employed taking the period of 1980 to 2008 the results show that energy consumption enables these countries to achieve high economic and financial development however the high development that these countries have achieved in the late three decades increased the co 2 emission it is important that these countries should reduce the level of pollution through utilizing energy protection policies such as rationing energy consumption and controlling carbon dioxide emissions or increasing the share of clean energy of their total energy consumption

do urbanization and industrialization affect energy intensity in developing countries abstract against a backdrop of concerns about climate change peak oil and energy security issues reducing energy intensity is often advocated as a way to at least partially mitigate these impacts this study uses recently developed heterogeneous panel regression techniques like mean group estimators and common correlated effects estimators to model the impact that income urbanization and industrialization has on energy intensity for a panel of 76 developing countries in the long run a 1 increase in income reduces energy intensity by 0 45 to 0 35 long run industrialization elasticities are in the range 0 07 to 0 12 the impact of urbanization on energy intensity is mixed in specifications where the estimated coefficient on urbanization is statistically significant it is slightly larger than unity the implications of these results for energy policy are discussed

short term forecasting of electricity prices for miso hubs evidence from arima egarch models this study estimates three time series models arima arima egarch and arima egarch m for hourly real time electricity prices for each of the five hubs of the midwest independent system operator miso and examines the in and out of sample forecasting performance of the respective models the results from the arima models reveal the presence of autoregressive conditional heteroskedasticity recognizing the possibility of asymmetric time varying volatility the egarch specification for the variance equation demonstrates the presence of an inverse leverage effect in electricity prices for each hub with respect to forecasts no one model clearly dominates the others in terms of in sample forecasting performance based on four forecast evaluation statistics however the arima egarch m model outperforms the other models michigan hub is the exception in terms of the out of sample forecasting performance

partisanship and economic behavior do partisan differences in economic forecasts predict real economic behavior survey data regularly show that assessments of current and expected future economic performance are more positive when a respondent s partisanship matches that of the president to determine if this is a survey artifact or something deeper we investigate whether partisanship is associated with behavioral differences in economic decisions we construct a new data set of county level quarterly taxable sales to examine the effect of partisanship on consumption consumption change following a presidential election is correlated with a county s partisan complexion a result consistent with partisans acting outside the domain of politics in accordance with the opinions they express in surveys these results support an expansive view of the role of partisanship in mass politics and help validate surveys as a method for studying political behavior

energy consumption and gdp revisited a panel analysis of developed and developing countries this paper applies a new panel data stationarity testing procedure first developed by carrion i silvestre et al 2005 econometrics journal 8 159 175 with panel vars that employ the generalized method of moment techniques in order to re investigate the dynamic interactions between energy consumption per capita lec and real gdp per capita lry in 22 developed and 18 developing countries when multiple breaks in the series are taken into account there is convincing evidence of panel stationarity for lec and lry in both groups the energy crises evidently had a substantive impact on both lec and lry in all sample countries furthermore our panel vars attest to bidirectional causality between lec and lry in developed countries but there is uni directional causality from lry to lec in developing countries finally from the orthogonalized impulse response functions all of the variables in the panel vars have a positive effect on each other but their impact is greater and more persistent in developing countries some important policy implications do emerge

energy consumption and economic growth in turkey during the past two decades the turkish economy has undergone a transformation from agricultural to industrial enhanced by rapid urbanization especially after 1982 turkey s gross national production has grown at an average annual rate of 5 since 1983 ranking it at the top of the oecd countries although the growth pattern has been uneven economic growth in recent years has been associated with the privatization of public enterprises turkey s energy demand has risen rapidly as a result of social and economic development the country s energy consumption has grown considerably since the beginning of the 1980s the turkish government encourages foreign and turkish private sector investors to implement the energy projects and is currently working on a new investment model for the construction of new generation plants to create the additional capacity needed the turkish energy sector with its current size of 30 billion us dollars and projected size of 55 billion us dollars by 2015 as well as the fundamental restructuring process it has been going through since 2001 attracts both local and foreign investors the sector needs an investment amount of approximately 130 billion us dollars by 2020 the aim of the present paper is to investigate the increasing of turkish energy demand with the growth of the economy and utilization of domestic energy sources and the case of investments and imports in turkey during the past two decades

economic growth and energy consumption revisited evidence from linear and nonlinear granger causality the relationship between energy consumption and economic growth is considered as an imperative issue in energy economics previous studies have ignored the nonlinear behavior which could be caused by structural breaks in this study both linear and nonlinear granger causality tests are applied to examine the causal relationship between energy consumption and economic growth for a sample of asian newly industrialized countries as well as the u s this study finds evidence supporting a neutrality hypothesis for the united states thailand and south korea however empirical evidence on philippines and singapore reveals a unidirectional causality running from economic growth to energy consumption while energy consumption may have affected economic growth for taiwan hong kong malaysia and indonesia policy implications are also discussed

impacts of urbanization on national transport and road energy use evidence from low middle and high income countries abstract few attempts have been made to investigate quantitatively and systematically the impact of urbanization on transport energy use for countries of different stages of economic development this paper examines the influence of urbanization on national transport and road energy use for low middle and high income countries during 1975 2005 using the stochastic impacts by regression on population affluence and technology stirpat model after controlling for population size income per capita and the share of services in the economy the main results suggest that urbanization influences national transport and road energy use positively however the magnitude of its influence varies among the three income groups changes in urbanization appear to have a greater impact on transport and road energy use in the high income group than in the other groups surprisingly the urbanization elasticities of transport and road energy use in the middle income group are smaller than those of the low income group this study not only sheds further light on the existing literature but also provides policy makers with insightful information on the link between urbanization and transport energy use at the three different stages of development

does urbanization affect energy intensities across provinces in china long run elasticities estimation using dynamic panels with heterogeneous slopes abstract although there has been extensive debate in the literature that addresses the impact of urbanization on total energy use the relative magnitude of each impact channel has not been empirically examined and urbanization s effects on energy transition dynamics in china remains unknown using panel datasets at the provincial level from 1986 to 2011 this paper employs dynamic models to investigate both the long run and short run elasticities of urbanization on energy intensities and the most significant impact channel is identified coal intensity and electricity intensity are also modeled to reveal energy transition dynamics driven by urbanization a set of newly developed regression techniques namely well performed common correlated effects mean group ccemg and augmented mean group amg estimators are used to treat residual cross sectional dependence nonstationary residuals and unlikely to hold homogeneous slope assumptions the results obtained verify that the net effects of urbanization on overall energy intensity and electricity intensity are statistically positive with long run elasticities of 0 14 to 0 37 and 0 23 to 0 29 respectively whereas china s urbanization does not significantly increase coal intensity the fact that short run elasticities account for a majority of corresponding long run values indicates that the short run effect that is indirect energy use induced by urban infrastructures is the most significant impact channel of urbanization on energy use in china an energy transition from high pollution coal to clean electricity is also present in china although the fundamental transition to renewable energy is still in its infancy from a regional perspective urbanization exerts asymmetric impacts on provincial energy use so that energy policies associated with urbanization should be province specific the findings also illustrate that for a panel dataset on regional dimension within large and fast growing economies such as china error cross sectional dependence and residual nonstationarity must be tested and properly treated to avoid size distortion and biased estimators

energy consumption and modes of industrialization four developing countries abstract because of heterogeneity of developing countries energy consumption dynamics can only be analysed at the level of individual countries this paper focuses on the comparison of the energy consumption dynamics of south korea india brazil and mexico and on the origins of the dynamics observed it is shown that the same factors explain the diversified energy consumption dynamics the national availability of energy resources the energy policies and the modes of industrialization adopted as well as the patterns of private consumption

energy consumption and economic growth the experience of african countries revisited abstract the aim of this paper is to re examine the causal relationship between energy consumption and economic growth for seventeen african countries in a multivariate framework by including labor and capital as additional variables we apply the variance decomposition analysis due to pesaran and shin pesaran m h and shin y generalised impulse response analysis in linear multivariate models economics letters 1998 58 17 29 to evaluate how important is the causal impact of energy consumption on economic growth relative to labor and capital the results of our multivariate modified granger causality analysis due to toda and yamamoto toda h y and yamamoto t statistical inference in vector autoregressions with possibly integrated process journal of econometrics 1995 66 225 250 tend to reject the neutrality hypothesis for the energy income relationship in fifteen out of the seventeen countries in contrast results of our variance decomposition analyses show that in eleven out of the seventeen countries energy is no more than a contributing factor to output growth and not an important one when compared to capital and labor labor and capital are the most important factors in output growth in fifteen out of the seventeen countries however these results should be interpreted with care as they may not be sufficiently robust enough to support the inference that energy consumption plays a minor role in the economic growth of african countries

residential electricity demand in taiwan this paper examines the residential demand for electricity in taiwan as a function of household disposable income population growth the price of electricity and the degree of urbanization short and long term effects are separated through the use of an error correction model in the long run the income elasticity is unit elastic the own price effect is negative and inelastic in an error correction framework the short run income and price effects are small and less than the long run effects cooling degree day effects have a positive impact on short run consumption we have used a proxy variable urbanization to capture economic development characteristics and changes in electricity using capital stocks not explained by income the variable provides significant explanatory power to the model both in the short and long run we interpret it as controlling for economic development factors not captured by the pure income effect and we think it holds promise for explaining residential electricity consumption in other developing countries

energy consumption carbon emissions and economic growth in china abstract this paper investigates the existence and direction of granger causality between economic growth energy consumption and carbon emissions in china applying a multivariate model of economic growth energy use carbon emissions capital and urban population empirical results for china over the period 1960 2007 suggest a unidirectional granger causality running from gdp to energy consumption and a unidirectional granger causality running from energy consumption to carbon emissions in the long run evidence shows that neither carbon emissions nor energy consumption leads economic growth therefore the government of china can purse conservative energy policy and carbon emissions reduction policy in the long run without impeding economic growth

an assessment of the danish german cross border auctions abstract this paper presents an analysis of the auction prices at the cross border auction between west denmark and germany and between east denmark and germany the kontek cable monthly and annual transmission capacities appear to be more highly valued than daily transmission capacity on average the two cross border auctions show different trends the auctions between west denmark and germany exhibit a higher level of prices in the southbound direction and between east denmark and germany higher prices in the northbound direction we find a relatively strong correspondence in the pricing of products over different time frames daily monthly and annual auctions between west denmark and germany and a weak correspondence for the products between east denmark and germany in the daily auctions market players can decide whether to use their capacity after the clearing of the day ahead market while in the monthly and annual auctions they must decide whether to use their capacity prior to clearing if they choose not to use their capacity the use it or lose it principle applies the capacity is then subsequently released to the daily market since the daily cross border auctions are free of commitment they should be valued as options likewise in the monthly and annual auctions market players can choose not to nominate their capacity but as this must occur before the clearing of the day ahead market they will not know the directions of the power flows a priori if they nominate the capacity they must use it if the direction turns out to be wrong it is then possible to purchase capacity in the opposite direction in the daily auctions if market players can accurately predict the outcome of the spot markets day ahead the value of monthly and annual capacity should more closely reflect the value of an option thus one would expect the value of the monthly and annual capacity to be between the value of an option and an obligation although this suggests that the average price of daily capacity should be greater than monthly and annual capacity our data do not support this hypothesis the daily monthly and annual capacity auctions do not reflect the value of the underlying asset as specified by the appropriate valuation of the energy price differentials between west denmark and germany and east denmark and germany therefore market players are exposed to substantial variation in fees for congestion management on the cross border we study whether arbitrage improves over time and discern no obvious trend since the explicit auction procedure has not been cost efficient a better approach appears to be the new market coupling arrangement introduced on the kontek cable and on the border between west denmark and germany with the result that market players will pay a congestion management fee i e area price difference equal to the energy price differential resulting from the market coupling mechanism

why and how to regulate power exchanges in the eu market integration context abstract the european union eu market integration is leading to increasingly monopolistic electricity market infrastructures which has opened a debate on the regulation of these so called power exchanges in this paper we start by stating that there are two types of power exchanges in europe i e merchant and cost of service regulated power exchanges we then discuss how regulation can be used to better align their incentives with the main power exchange tasks we conclude that adopting the cost of service regulated model for all power exchanges in europe could be counterproductive in the current context but that regulation can help ensure that the benefits of the eu market integration materialize promising regulatory actions include tempering the reinforced market power of power exchanges and quality of service regulation for the ongoing cooperation among power exchanges to organize trade across borders

how much have electricity shortages hampered china s gdp growth abstract based on an econometric analysis of the annual growth data for china s gdp and electricity generation from 1953 to 2010 we find that electricity generation growth granger causes gdp growth but not vice versa we also find that the gdp elasticity of electricity generation is about 0 6 implying that a 1 increase in china s electricity generation growth would increase gdp growth by 0 6 while deng s reform raised china s gdp growth rate by about 5 per year it did not alter the gdp elasticity of electricity generation hence an obvious strategy to promote china s economic growth would be accelerating electricity generation expansion rapidly adding thermal generation units however could have large scale adverse environmental impacts we therefore support china s 2011 five year plan which calls for expanding investments in renewable energy conservation and energy efficiency as well as improving china s integrated electricity planning and cost based pricing decisions

the relationship between disaggregate energy consumption and industrial production in the united states an ardl approach abstract we re examine the relationship between disaggregate energy consumption and industrial output as well as employment in the united states using the autoregressive distributed lag ardl approach developed by pesaran and pesaran pesaran m h pesaran b 1997 working with microfit 4 0 camfit data ltd cambridge and pesaran shin and smith pesaran m h shin y smith r j 2001 bounds testing approaches to the analysis of level relationships journal of applied econometrics 16 289 326 in particular we focus attention on the following energy consumption variables coal fossil fuels conventional hydroelectric power solar energy wind energy natural gas wood and waste the sample period covers 2001 1 2005 6 our results imply that real output and employment are long run forcing variables for nearly all measures of disaggregate energy consumption

energy consumption and gdp in turkey is there a co integration relationship energy consumption and gdp are expected to grow by 5 9 and 7 annually until 2025 in turkey this paper tries to unfold the linkage between energy consumption and gdp by undertaking a co integration analysis for turkey with annual data over the period 1970 2003 the analysis shows that energy consumption and gdp are co integrated this means that there is a possibly bi directional causality relationship between the two we establish that there is a unidirectional causality running from gdp to energy consumption indicating that energy saving would not harm economic growth in turkey in addition we find that energy consumption keeps on growing as long as the economy grows in turkey

how urbanization affects energy use in developing countries abstract this paper identifies mechanisms whereby urbanization affects energy consumption industrialization and urbanization accompany each other during economic development but urbanization exerts a number of independent influences on energy use it permits economies of scale in production but requires more transportation food must be transported to urbanized populations and relatively smaller agricultural populations must modernize entailing considerable increases in agricultural energy use in cities a number of production activities which were domestically provided in rural areas using human or animal energy shift to sources outside the household using modern energy sources the largest single source of change in energy use is personal transportation passenger transport in cities is heavily weighted towards fuel using modes particularly as incomes increase to assess the overall impact a regression analysis of 59 developing countries for 1980 is conducted holding constant per capita income and the extent of industrialization the elasticity of energy consumption per capita and per dollar of gdp is between 0 35 and 0 48

factors determining energy consumption evidence from indonesia malaysia and thailand abstract the aim of this study is to verify empirically the impact of various factors on energy consumption in three asean countries namely indonesia malaysia and thailand over the period 1980 to 2012 after using sundry appropriate diagnostic tests for checking time series data the method of least square as an analytical technique is used for parameters estimation the findings validate that fdi inflows economic growth trade openness and human development index have positive and statistically significant impacts on energy consumption the other variable urbanization has positive and statistically significant impacts on energy consumption for thailand and indonesia only while the empirical results reveals that population growth rate has a positive and statistically significant relationship with energy consumption only in the case of malaysia so in the light of determinations of the study the policy implication is that energy policy needs to be orientated in favor of expanding the supply of energy to reach an enhanced degree of sustainable economic growth and development

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

energy consumption and economic growth in central america evidence from a panel cointegration and error correction model abstract this study examines the relationship between energy consumption and economic growth for six central american countries over the period 1980 2004 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 based on the heterogeneous panel cointegration test by pedroni pedroni p 1999 critical values for cointegration tests in heterogeneous panels with multiple regressors oxford bulletin of economics and statistics 61 653 670 pedroni p 2004 panel cointegration asymptotic and finite sample properties of pooled time series tests with an application to the ppp hypothesis new results econometric theory 20 597 627 cointegration is present between real gdp energy consumption the labor force and real gross fixed capital formation with the respective coefficients positive and statistically significant the granger causality results indicate the presence of both short run and long run causality from energy consumption to economic growth which supports the growth hypothesis
