geo economic approach to energy security measurement principal component analysis abstract currently there is no single accepted methodology for measuring energy security while the prevailing scientific attitude is that energy security should be defined and quantified in a way to be able to follow rapid developments on the global economic and geopolitical scene considering the fact that the national economies represent an integral part of a dynamic international economy where external shocks global financial and economic crisis political conflicts war etc have the impact on energy prices and energy security in general the paper proposes a new geo economic concept of energy security the new approach differs from the existing ones as regards the fact that in addition to basic indicators it takes into account sovereign credit rating as a measure of economic financial and political stability as one of the decisive factors which determines global energy trade and the ability of national economies to be stable and secure when it comes to energy determination and testing of geo economic index of energy security was conducted by using the principal component analysis in the european union and in the selected countries of the world over a period of ten years 2004 2013 the measured values of a newly proposed geo economic index of energy security demonstrate significant deviations from the data obtained by using usual indicators of energy security observed individually gdp per capita has the greatest impact on the change in final value of geo economic index of energy security while the impact of sovereign credit rating is slightly less the study has shown that the least impact on energy security is exerted by energy dependence which is traditionally used as a proxy indicator of energy security and production of energy from renewable sources which is defined by the eu policy as one of the methods for the improvement of energy security due to the results obtained it is necessary to conduct further analysis of sovereign credit rating and to review the type and significance of the impact of energy dependence indicator as a measure of energy security in general

oil vulnerability index of oil importing countries abstract this paper assesses the relative oil vulnerability of 26 net oil importing countries for the year 2004 on the basis of various indicators the ratio of value of oil imports to gross domestic product gdp oil consumption per unit of gdp gdp per capita and oil share in total energy supply ratio of domestic reserves to oil consumption exposure to geopolitical oil market concentration risks as measured by net oil import dependence diversification of supply sources political risk in oil supplying countries and market liquidity the approach using the principal component technique has been adopted to combine these individual indicators into a composite index of oil vulnerability such an index captures the relative sensitivity of various economies towards developments of the international oil market with a higher index indicating higher vulnerability the results show that there are considerable differences in the values of individual indicators of oil vulnerability and overall oil vulnerability index among the countries both inter and intraregional

modelling sovereign credit spreads with international macro factors the case of brazil 1998 2009 abstract this paper develops a macro finance model of the brazilian economy and its sovereign debt markets that allows for domestic and international macroeconomic influences as well as swings in investor confidence it finds significant evidence of common trends in the us and brazilian economies and bond markets as well as spillover effects from us inflation and business cycles to the brazilian economy the us fed funds rate influences brazilian sovereign spreads as do brazilian inflation and policy rates the brazilian confidence factor dominates the behavior of the spreads during periods of crisis and we find that it also has a powerful effect on the level and volatility of macroeconomic variables these results suggest that the macro finance approach could throw light upon the behavior of other economies that are troubled by sovereign risk

the determinants of household risky asset holdings australian evidence on background risk and other factors we study the portfolio allocation decisions of australian households using the relatively new household income and labour dynamics in australia hilda survey we focus on household allocations to risky financial assets our empirical analysis considers a range of hypothesised determinants of these allocations we find background risk factors posed by labor income uncertainty and health risk are important credit constraints and observed risk preferences play the expected role a positive age gradient is identified for risky asset holdings and home ownership is associated with greater risky asset holdings a unifying theme for many of our empirical findings is the important role played by financial awareness and knowledge in determining risky asset holdings many non stockholding households appear to lack the experience and financial literacy that might enable them to benefit from direct investment in stocks

stock market expectations of dutch households despite its importance for the analysis of life cycle behavior and in particular retirement planning stock ownership by private households is poorly understood among other approaches to investigate this puzzle recent research has started to elicit private households expectations of stock market returns this paper reports findings from a study that collected data over a two year period both on households stock market expectations subjective probabilities of gains or losses and on whether they own stocks we document substantial heterogeneity in financial market expectations expectations are correlated with stock ownership over the two years of our data stock market prices increased and expectations of future stock market price changes also increased lending support to the view that expectations are influenced by recent stock gains or losses

subjective expectations experiences and stock market participation evidence from the lab abstract recent evidence suggests that stock market experiences i e realized returns impact subjective expected returns i bring a model into the laboratory and find that experience based subjective expected returns can help explain limited stock market participation in the experiment the probability of subjects participating in the stock market is increasing in both their subjective expected returns and past realized returns i find that learning from experience generates heterogeneity in subjective expected returns where subjects who experience low returns have lower subjective expected returns than subjects who only observe low returns this experience effect is asymmetric where subjects who experience high returns have no statistically significant difference in their subjective expected returns than subjects who only observe high returns finally after a series of low returns a fraction of subjects leave the stock market indefinitely

chinese energy investments in europe an analysis of policy drivers and approaches abstract enhancing the understanding of china eu energy relations the article examines chinese energy investments in europe from 2008 to 2015 and analyzes the energy interests and policy approaches underpinning them analysis of this data shows that within the eu 30 chinese investments largely focused on the oil and gas sector especially through the acquisition of company shares chinese energy investments in europe reflect a clear political and commercial strategy that addresses the prc s need to balance supply chain security of fossil fuels environmentally friendlier energy production and use as well as to enhance the market position and energy industrial capabilities of chinese state owned or state supervised energy companies based on a comprehensive set of domestic incentives for international investment the chinese penetration of the european energy sector is embedded within two levels of political cooperation the first level revolves around bilateral investment agreements between china and 27 eu member states on the second level china and the eu have established a variety of formats that guide their energy cooperation the conclusion of the proposed bilateral investment agreement between the prc and the eu would create a uniform investment environment across the continent and facilitate mutual economic benefits for both parties

trade offs in energy and environmental policy abstract the energy sector is undeniably undergoing a critical period faced with multiple challenges whether economic political or technological these challenges are related to the requirements set on the sector to meet a wide range of social demands associated with the three traditional dimensions of a sustainable energy system i e environmental sustainability security of energy supply and economic sustainability in particular the environmental pillar has gained ground after the paris agreement which has reinforced the requirement of a low carbon transformation of the sector a main challenge is to balance trade offs among competing goals when designing energy and environmental policies although making the energy sector greener is a common aspiration of governments and many countries are indeed being successful in this regard the success comes at a price in terms of the other non environmental dimensions of a sustainable energy system the aim of this special issue is to look in detail on some of the most pressing environmental challenges faced by the energy sector as well as the trade offs involved in reaching a greener energy system

the role of fixed costs and cost complementarities in determining scope economies and the cost of narrow banking proposals narrow banking proposals would separate insured deposits from most types of bank lending using data from large u s banks the authors examine the extent to which narrow banking proposals are likely to result in increased production costs production costs will rise for nonjoint provision of deposit and loan services if there are cost complementarities in producing the two outputs jointly or if joint production enables banks to spread their fixed costs more effectively unlike standard cost function approaches the authors methods allow them to estimate the fixed cost and cost complementarity effects separately they find the net production cost consequences of narrow banking to be negligible copyright 1993 by university of chicago press

exploring the relationship between energy use and economic growth with bivariate models new evidence from g 7 countries abstract there is a rapidly growing literature on the interaction between energy use and economic development with many analysts drawing policy conclusions on the basis of granger causality tests that involve only an energy and an economic variable this paper attempts to demonstrate empirically that such studies although useful for certain applications may be of limited use for policy purposes after outlining theoretical and methodological issues associated with such approaches i apply bivariate energy economy causality tests for canada france germany italy japan the united kingdom and the united states using aggregate and sectoral data and three different modern econometric methods the results which are often contradictory or economically implausible illustrate explicitly that one should be cautious when drawing policy implications with the aid of bivariate causality tests on small samples i therefore underline the importance of utilizing as large sample sizes as possible and using multivariate models which are closer to economic theory accommodate several mechanisms and causality channels and provide a better representation of real world interactions between energy use and economic growth

measuring energy security can the united states achieve oil independence stochastic simulation of the direct economic costs of oil dependence in an uncertain future is proposed as a useful metric of oil dependence the market failure from which these costs arise is imperfect competition in the world oil market chiefly as a consequence of the use of market power by the organization of the petroleum exporting countries opec cartel oil dependence costs can be substantial it is estimated that oil dependence costs to the us economy in 2008 will exceed 500 billion other costs such as military expenditures or foreign policy constraints are deemed to be largely derivative of the actual or potential economic costs of oil dependence the use of quantifiable economic costs as a security metric leads to a measurable definition of oil independence or oil security which can be used to test the ability of specific policies to achieve oil independence in an uncertain future

a framework for analyzing efficiency risks costs and innovations in the payments system the market for payment instruments such as cash checks and electronic funds transfers is one of the largest most important and economically interesting markets in the economic system virtually every economic transaction requires the use of a payment instrument therefore on a value basis the demand for payment instruments equals the demand for all other goods services assets and other financial instruments traded in the economy combined in a monetary economy the buyers and sellers of any commodity must not only agree on the price and quantity to be exchanged but must also concur on the payment method that will be employed in the exchange that is every commodity buyer takes on the role of a payor and every commodity seller takes on the role of a payee and they jointly demand a payment instrument of equal value to the commodities exchanged the size of payments markets is illustrated in table 1 which shows transactions

scale economies cost efficiencies and technological change in federal reserve payments processing the payments system the means of conducting transactions in an economy hume s oil has undergone tremendous change over the centuries commodity money was replaced by fiat usually paper money reducing transportation and storage costs the invention of checks to supplement fiat money further reduced transportation and storage costs lessened the problem of theft and provided a record of transactions most recently the advent of electronic payment instructions has greatly reduced the time and handling costs associated with checks between the great evolutionary leaps forward that gave rise to new forms of payment instructions smaller degrees of gradual evolution occurred within each payment mechanism refining and improving them and reducing the costs associated with their use

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

new evidence on the fed s productivity in providing payments services abstract as the dominant provider of payments services the efficiency with which the federal reserve provides such services is an important public policy issue this paper examines the productivity of federal reserve check processing offices during 1980 1999 using non parametric estimation methods and newly developed methods for non parametric inference and hypothesis testing the results support prior studies that found little initial improvement in the fed s efficiency with the imposition of pricing for federal reserve services in 1982 however we find that median productivity improved substantially during the 1990s and the dispersion of productivity across fed offices declined

financial literacy and consumer credit portfolios we use survey data from a sample of uk households to analyse the relation ship between financialliteracy and consumer credit portfolios we show that individ uals who borrow on consumer credit exhibit worse financial literacy than those who do not borrowers with poor financialliteracy hold higher shares of high cost credit such as home collected credit mail order catalogue debt and payday loans than those with higher literacy we also show that individuals with poor financialliteracy are more likely to lack confidence when interpreting credit terms and to exhibit confusion over financialconcepts they are also less likely to engage in behaviour which might help them to improve their awareness of the credit market

indicators of energy security in industrialised countries energy security has become a popular catch phrase both in the scientific arena as well as in the political discussion yet in general the applied concepts of energy security are rather vague this paper sheds some light on concepts and indicators of energy security first we conceptually discuss the issue of energy supply security and explain why it is not to handle by one science alone and what economics may contribute in order to structure the topic after providing a brief survey of existing attempts to define or measure energy security we suggest an additional dimension along which indicators of energy security may be classified ex post and ex ante indicators finally we illustrate our concept on the basis of several simplified indicators while ex post indicators are mostly based on price developments ex ante indicators are to a greater extent aimed at illustrating potential problems our illustration suggests that it is worthwhile to take into account the market structure along with the political stability of exporting countries

global energy security and the implications for the eu abstract the following article will analyse the global and geopolitical dimensions of the future international energy security and its implications for europe and the eu 27 in this context i will discuss to which extent the eu s newly proclaimed energy action plan of the eu spring summit of 2007 and its declared common energy foreign policy are a sufficient strategy to cope with the new global and geopolitical challenges the article concludes the following 1 the interlinkage between globally designed traditional energy security concepts that rely just on economic factors and market strategies and domestic as well as regional political stability demands new thinking with regard to both energy supply security and foreign and security policies 2 although after the russian ukrainian gas conflict in january 2006 energy security has forced its way up the european energy and foreign policy agendas the eu 27 member states have largely failed to forge a coherent european energy security and energy foreign policy strategy after their spring summit of 2007 because its declared political solidarity has been still lacking but the 2nd strategic energy review of november 2008 has recommended new initiatives to overcome this lack by promoting concrete infrastructure and other projects for enhancing europe s supply security and its political solidarity as part of a common energy foreign policy if the eu is able to implement the march 2007 and november 2008 decisions the eu oil and gas demand will drastically reduce and freeze at current levels in this case putin s energy policies by using russia s energy resources and pipeline monopolies as a political instrument to enforce its economic and geopolitical interests will be proved as self defeating in russia s long term strategic interests it will reduce gazprom s gas exports to a much smaller eu gas market than originally forecasted as the result of a deliberate eu policy of decreasing its overall gas demand and by diversifying its gas imports

genetic variation in financial decision making individuals differ in how they construct their investment portfolios yet empirical models of portfolio risk typically account only for a small portion of the cross sectional variance this paper asks whether genetic variation can explain some of these individual differences following a major pension reform swedish adults had to form a portfolio from a large menu of funds we match data on these investment decisions with the swedish twin registry and find that approximately 25 of individual variation in portfolio risk is due to genetic variation we also find that these results extend to several other aspects of financial decision making

heterogeneity in expectations risk tolerance and household stock shares the attenuation puzzle this article jointly estimates the relationship between stock share and expectations and risk preferences the survey allows individual level quantitative estimates of risk tolerance and of the pe

sovereign credit rating determinants a comparison before and after the european debt crisis this paper compares the importance of different sovereign credit rating determinants over time using a sample of 90 countries for the years 2002 2015 applying the composite marginal likelihood approach we estimate a multi year ordered probit model for each of the three major credit rating agencies after the start of the european debt crisis in 2009 the importance of the financial balance the economic development and the external debt increased substantially and the effect of eurozone membership switched from positive to negative in addition gdp growth gained a lot of importance for highly indebted sovereigns and government debt became much more important for countries with a low gdp growth rate these findings provide empirical evidence that the credit rating agencies changed their sovereign credit rating assessment after the start of the european debt crisis

explaining credit default swap spreads by means of realized jumps and volatilities in the energy market abstract this paper studies the relationship between credit default swap cds spreads for the energy sector and oil futures dynamics using data on light sweet crude oil futures from 2004 to 2013 which contains a crisis period we examine the importance of volatility and jumps extracted from the futures in explaining cds spread changes the analysis is performed at an index level and by rating group as well as for the pre crisis crisis and post crisis periods our findings are consistent with merton s theoretical framework at an index level futures jumps are important when explaining cds spread changes with negative jumps having higher impact during the crisis the continuous volatility part is significant and positive indicating that futures volatility conveys relevant information for the cds market as for the analysis per rating group negative jumps have an increasing importance as the credit rating deteriorates and during the crisis period while the results for positive jumps and futures volatility are mixed overall the relation between the cds market and the futures market is stronger during volatile periods and strengthened after the global financial crisis

differing cultures of energy security an international comparison of public perceptions this study reviews how energy users perceive the importance of energy security dimensions it asks how does the sense of energy security vary with culture its primary source of data is a summary of survey distributed in eight languages to almost 2500 respondents in brazil china denmark germany india kazakhstan japan papua new guinea saudi arabia singapore and the united states it utilizes an energy literacy test in denmark as a secondary data tool the survey results are used to test nine hypotheses about national economic political professional and epistemic cultures the study concludes by affirming the complexity of energy security as a cultural topic by emphasizing how answers among respondents tended to converge more than diverge and by calling for further research

robustly strategic consumption portfolio rules with informational frictions this paper provides a tractable continuous time constant absolute risk aversion gaussian framework to explore how the interactions of fundamental uncertainty model uncertainty due to a preference for robustness and state uncertainty due to information processing constraints rational inattention affect strategic consumption portfolio rules and precautionary savings in the presence of uninsurable labor income specifically after solving the model explicitly i compute and compare the elasticities of strategic asset allocation and precautionary savings to risk aversion robustness and inattention furthermore for plausibly estimated and calibrated model parameters i quantitatively analyze how the interactions of model uncertainty and state uncertainty affect the optimal share invested in the risky asset and show that they can provide a potential explanation for the observed stockholding behavior of households with different education and income levels this paper was accepted by neng wang finance

risk spillovers in oil related cds stock and credit markets abstract this paper examines risk transmission and migration among six us measures of credit and market risk during the full period 2004 2011 period and the 2009 2011 recovery subperiod with a focus on four sectors related to the highly volatile oil price there are more long run equilibrium risk relationships and short run causal relationships among the four oil related credit default swaps cds indexes the expected equity volatility vix index and the swaption expected volatility smove index for the full period than for the recovery subperiod the auto sector cds spread is the most error correcting in the long run and also leads in the risk discovery process in the short run on the other hand the cds spread of the highly regulated natural monopoly utility sector does not error correct the four oil related cds spread indexes are responsive to vix in the short and long run while no index is sensitive to smove which in turn unilaterally assembles risk migration from vix the 2007 2008 great recession seems to have led to localization and less migration of credit and market risk in the oil related sectors

scale economies scope economies and technical change in federal reserve payment processing in the past decade the u s economy has witnessed a tremendous surge in the usage of electronic payment processing services and an increased importance of the firms that provide these services in this paper we estimate scale economies scope economies and technical change in the federal reserve s provision of payments processing from 1990 to 2000 we find considerable scale economies and evidence of some scope economies for the provision of automated clearinghouse fedwire and book entry services no matter whether we specify a separable quadratic or a translog cost function in addition we find that disembodied technical change also contributed to the overall reduction in costs throughout the 1990s

a composite cost function for multiproduct firms with an application to economies of scope in banking the composite cost function the authors propose combines a quadratic output structure with a log quadratic input price structure and is well suited for examining economies of scope subadditivity and other important properties of multiproduct firms to compare the composite model with an appropriate set of alternative functional forms they develop a parsimonious but general specification that nests the standard translog cost function the generalized translog cost function a separable quadratic cost function and the composite cost function an application to economies of scope in banking confirms the advantages of the composite model copyright 1992 by mit press

structural shifts in credit rating standards i examine the time series variation in corporate credit rating standards from 1985 to 2007 a divergent pattern exists between investment grade and speculative grade rating standards from 1985 to 2002 as investment grade standards tighten and speculative grade loosen in 2002 a structural shift occurs toward more stringent ratings holding characteristics constant firms experience a drop of 1 5 notches in ratings due to tightened standards from 2002 to 2007 credit spread tests suggest that the variation in standards is not completely due to changes in the economic climate rating standards affect credit spreads loose ratings are associated with higher default rates

payment transactions instruments and systems a survey the payments literature ranges from theoretical general equilibrium models to practical payment issues related to the day to day operation of various national networks for the transfer of money it is an area where economic theory and institutional structure are often closely intertwined and it is currently undergoing significant change shifting from costly paper based systems to technologically advanced electronic payments the extant literature is surveyed here with the aim of integrating the various strands of payment research which have been largely pursued separately in addition we present newly available data to illustrate and investigate a number of underdeveloped areas in this literature 1998 elsevier science b v all rights reserved

financial system design and liquidity provision by banks and markets in a dynamic economy this paper contributes to the literature on financial system design by comparing markets and banks in a dynamic economy investors trade off their liquidity needs against the high returns on illiquid investments both the banking system and the market can provide partial liquidity insurance to investors we consider full market participation as well as limited market participation we demonstrate that the full participation market with intergenerational trading can provide more liquidity than one without insurance is provided through wealth transfer across generations instead of cross subsidization across contemporaneous types as is the case in the finite economy given a full participation market that allows trading across generations only banks with initial capital can provide additional liquidity in a limited participation market with uncertainty about trading types an intergenerational bank with or without initial capital provides additional insurance to investors the need for trade is eliminated finally if there is no uncertainty about trading types then an intergenerational bank with initial capital eliminates the need for trading and improves welfare for all an intergenerational bank without initial capital improves welfare for people who do not trade

why do so few hold stocks the authors investigate why 75 percent of u s households do not hold stocks despite the equity premium and predictions of expected utility models the question is relevant for privatization asset pricing and tax progressivity issues they show that risk aversion per se heterogeneity of beliefs habit persistence time nonseparability and quantity constraints on borrowing do not account for the phenomenon a wedge between borrowing and lending rates and minimum investment requirements are plausible but empirically weak factors more promising explanations are inertia and departures from expected utility maximization there is also qualified support for nondiversifiable income risk as a contributing factor copyright 1995 by royal economic society

asset market participation and portfolio choice over the life cycle using error free data on life cycle portfolio allocations of a large sample of norwegian households we document a double adjustment as households age a rebalancing of the portfolio composition away from stocks as they approach retirement and stock market exit after retirement when structurally estimating an extended life cycle model the parameter combination that best fits the data is one with a relatively large risk aversion a small per period participation cost and a yearly probability of a large stock market loss in line with the frequency of stock market crashes in norway

resource nationalism and credit growth in fsu countries this paper analyses the connection between resource nationalism and financial sector intervention in the fsu countries we consider recent financial development in the fsu and the special features of energy rich emerging economies russia and kazakhstan in particular which are influencing recent credit expansions we find that the hydrocarbon sector has boosted boosting domestic credits through a number of direct and indirect routes recent decline in oil prices may change government attitudes to a continued resource nationalist strategy sovereign wealth funds that were established in a majority of energy rich emerging economies may to the extent that they enable the selection of winners in specific economic sectors create path dependency or exacerbate longer term allocative inefficiency arising from the governance structure associated with resource nationalism

strengthening of energy security low carbon growth in asia role of regional energy cooperation through trade abstract prudent demand supply management of energy is pivotal for the energy security of the countries and transitions towards the sustainable low carbon energy system this study empirically investigates the existing demand supply gaps of energy in the south though east asian stea countries and analyzes how the gaps can be minimized most efficiently through intraregional energy trade stochastic frontier gravity model extended with the determinants of efficiency models used for both primary energy and renewable energy goods reg trade the result implies that for most of the countries intraregional export of primary energy as well as reg are positively influenced by gross domestic products gdp of the exporting and importing countries tariff and distance adversely affect the exports while the implication of cross exchange ratio seems minimal in both cases regional trade agreements rta are also found to have notable positive impact on intraregional trade results show that china and thailand are the most efficient in this intraregional primary energy export while bangladesh and myanmar remain the least efficient china and japan are the most efficient in reg exports while bangladesh remains the least efficient on average the whole region has the weighted export efficiency of 56 5 in intraregional primary energy trade and 63 1 in reg trade the determinants of efficiency model reveals that institutional quality better infrastructure goods market efficiency and technological readiness have reasonable impacts to enhance the countries intraregional energy trade efficiencies

energy security measurement a sustainable approach abstract the main objective of this paper is to define new energy security indicator with the long term sustainability and to test it in a sample of 28 european union countries for the period 1990 2012 as well as to determine the level of impact of six different indicators on energy security the previous methodologies for measuring of energy security have been mainly focused on security of supply while not taking into account environmental indicators and the social component the newly proposed indicator energy security index differs from the existing measuring methods precisely in a way that it includes environmental and social aspects energy security index recorded a decline in values in most countries in the period 1990 2000 in the period 2000 2008 the values became positive and after 2008 some countries reported again gradual deterioration the index value varies by year and the biggest positive changes were recorded in the case of the netherlands slovenia and spain the four economically strongest eu countries the united kingdom france germany and italy recorded significantly less fluctuations in energy security over 23 years compared to other countries the data for france and denmark show that an increased share of energy from nuclear and renewable sources can compensate even increased energy import dependence the assessment of impact of individual indicators on energy security index was conducted by using principal component analysis and showed that energy intensity gdp per capita and carbon intensity have the greatest impact the countries of the former eastern bloc are facing particular challenges of energy security which is primarily related to the rapid economic growth and at the same time a high degree of dependence on import of energy generating products in terms of energy security the most stable transition was reported in hungary and poland

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
