factor demand technical change and inter fuel substitution in africa abstract the translog production function has been widely used in applied production analysis due to its flexibility and superiority over other functional forms this study develops a translog production function for a group of african countries the random effects model is estimated using generalized least squares estimator the main findings are first output in africa is driven by a more intensive use of petroleum and electricity and to a lesser extent capital labor and coal relative to technological progress second african production technology exhibits increasing returns to scale suggesting a path towards market entry barriers third technical change is scale biased and factor augmenting albeit very slow fourth all energy inputs are substitutes indicating africa s potential to proportionally switch towards cleaner fuels without adversely affecting economic growth finally and perhaps more generally the study reinforces the assertion that imposing restrictions like homotheticity homogeneity or separability on the production technology is unrealistic and should rather be a testable hypothesis within any applied analysis in view of the documented findings relevant implications for africa are discussed

on electricity consumption and economic growth in china abstract the invention and application of the electric power technology triggered the second industrial revolution in human history which marked the human society entered the age of electricity electricity provides the sustainable power for economic and social development with the rapid development of economy the electricity consumption is also increasing the increase of electricity consumption has further promoted the progress of the industrial economy in order to achieve the goal of improving the level of economic development while reducing energy consumption it is necessary to reveal the relationship between electricity consumption and economic growth this study is an extensive overview of the literature surrounding this topic in this paper we focus on the relationship between electricity consumption and economic growth in china we first analyze the general situation of china s electricity consumption and economic development then we explore the relationship between china s electricity consumption and economic growth from three dimensions i e the time dimension the regional dimension and the industrial dimension finally we study the key issues in the research of the relationship between electricity consumption and economic growth including variable selection model construction and results discussion this work suggests that the nature of the nexus in china should and can be explored from a wider perspective by developing a suitable integrated methodological framework

the armed peace a punctuated equilibrium theory of war according to a leading rationalist explanation war can break out when a large rapid shift of power renders unbelievable a rising state s promise to compensate its declin ing opponent causing the latter to attack preventively this mechanism does not provide a complete and coherent explanation of war because it does not specify how inefficient fighting resolves this commitment problem we present a complete information model of war as a sequence of battles and show that although opportunities for a negotiated settle ment arise throughout the very desirability of peace creates a commitment problem that undermines its likelihood because players have incentives to settle as soon as possible they cannot credibly threaten to fight long enough if an opponent launches a surprise at tack this decreases the expected duration and costs of war and causes mutual deterrence to fail fighting s sheer destruction improves the credibility of these threats by decreasing the benefits from continuing the war equilibrium fighting may involve escalating costs that exceed the value of the stakes by the time peace is negotiated and that leave both players worse off than when the war began

a dynamic panel study of economic development and the electricity consumption growth nexus abstract this study examines the relationship between electricity consumption and economic growth for 88 countries categorized into four panels based on the world bank income classification high upper middle lower middle and low income within a multivariate panel framework over the period 1990 2006 the larsson et al 2001 panel cointegration test indicates there is a long run equilibrium relationship between real gdp coal consumption real gross fixed capital formation and the labor force for the high upper middle and lower middle income country panels the results from the panel vector error correction models reveal 1 bidirectional causality between electricity consumption and economic growth in both the short and long run for the high income and upper middle income country panels 2 unidirectional causality from electricity consumption to economic growth in the short run but bidirectional causality in the long run for the lower middle income country panel and 3 unidirectional causality from electricity consumption to economic growth for the low income country panel

environmental kuznets curve in romania and the role of energy consumption abstract the aim of present study is to probe the dynamic relationship between economic growth energy consumption and co 2 emissions for period of 1980 2010 in case of romania in doing so ardl bounds testing approach is applied to investigate the long run cointegration between these variables our results confirm long run relationship between economic growth energy consumption and energy pollutants the empirical evidence reveals that environmental kuznets curve ekc is found both in long and short runs in romania further energy consumption is major contributor to energy pollutants democratic regime shows her significant contribution to decline co 2 emissions through effective implementation of economic policies and financial development improves environment i e reduces co 2 emissions by redirecting the resources to environment friendly projects

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

the effect of business risk on corporate capital structure theory and evidence under corporate and personal taxation we demonstrate that the relation between optimal debt level and business risk is roughly u shaped this result follows from the fact that the tax liability is an option portfolio that is long in the corporate tax option and short in the personal tax option therefore the net effect of a change in business risk on the optimal debt level depends upon the relative magnitudes of the resultant marginal changes in the values of these two options results of empirical tests offer support for the predicted u shaped relationship

energy production system optimization evidence from pakistan abstract the ongoing energy crisis in pakistan and the dependency on thermal electricity generation has contributed to the necessity to optimize energy production system the expensive thermal electricity and inability to recover its cost gives unprecedented rise to the electricity tariffs in this study optimization of the energy production system has been performed using linear programing model as the high cost of electricity generation has been found as the root cause of energy crises the objective function of the proposed model is cost minimization that will also reduce the circular debt specifically it has examined the optimum proportion of energy production from each available source under two different scenarios the first scenario considers that the existing system should be used at its maximum capacity in the second scenario seventy percent utilization of power plants has been examined the second scenario summarizes the optimum mix of energy production which minimizes the cost of electricity production the differential cost that is payable by the government as a subsidy is also compensated similarly it reduces circular debt that is a bottleneck between power generation companies and oil supply companies thus the proposed model has a tendency to minimize the cost of energy production and further reduce circular debt as well as the burden of a subsidy on the government the study specifies the problems confronting pakistan s energy sector and identifies the key elements of a potential policy response to address the country s severe power crisis

economic growth and electricity consumption in cote d ivoire evidence from time series analysis this paper examines the causal relationship between the electric power industry and the economic growth of cote d ivoire using the data from 1971 to 2008 a test was conducted for the cointegration and granger causality within an error correction model results from these tests reveal a bidirectional causality between per capita electricity consumption and per capita gdp a unidirectional causality running from electricity consumption to industry value added appears in the short run economic growth is found to have great effects on electricity consumption and a reverse causality from electricity to economic growth may also appear in the long run there is a unidirectional causality between electricity and both gdp and industry value added from these findings we conclude that the country will be energy dependent in the long run and must therefore secure the production network from shortfalls to ensure a sustainable development path accordingly government should adopt policies aimed at increasing the investment in the sector by stepping up electricity production from existing and new energy sources

the relationship between economic growth and electricity consumption from renewable and non renewable sources a study of turkey abstract the main objective of this study is to analyze the short and long run estimates as well as the causality relationships between economic growth gr electricity consumption from renewable sources relc and electricity consumption from non renewable sources nrelc for turkey in a multivariate model wherein capital k and labor l are included as additional variables using the autoregressive distributed lag ardl approach to cointegration the johansen cointegration test and the gregory hansen cointegration test with structural break we show that gr relc nrelc k and l are cointegrated although nrelc has a long run positive effect on gr the long run estimate of relc is negative but insignificant at 5 level of significance the granger causality test based on the vector error correction model reveals the evidence of neutrality hypothesis between relc and gr and between nrelc and gr in turkey in the short run in addition the granger causality runs from relc nrelc k and l to gr as well as from gr relc k and l to nrelc in the long run which supports the existence of growth hypothesis between relc and gr and feedback hypothesis between nrelc and gr in the long run it is advised that policy makers in the turkish government should continue to reduce the share of electricity consumption from renewable sources and encourage the usage of electricity from non renewable sources to have sustainable long run growth rates it is also essential to promote the investment projects to increase the efficiency of electricity generation from non renewable sources

the costs of conflict abstract violent conflict destroys resources it generates destruction costs these costs have an important effect on individuals decisions to cooperate or conflict we develop two models of conflict one in which conflict s destruction costs are independent of individuals investments in arms the tools of conflict and another in which conflict s destruction costs depend on those investments our models demonstrate that when conflict s destruction costs are arms dependent conflict is more costly making cooperation more likely we test this prediction with a laboratory experiment in which subjects first choose how heavily to invest in arms and then choose whether to cooperate or conflict in an environment where interaction is repeated in one set of treatments conflict s destruction costs are arms independent in another they are arms dependent our experimental results support our models predictions compared to when conflict s destruction costs are arms independent when those costs are arms dependent cooperation increases by nearly a third

natural gas consumption and economic growth nexus panel data analysis for gcc countries abstract this study investigates the relationship between natural gas energy consumption and economic growth by including trade openness total labor force and gross fixed capital formation as a major determinants of gdp growth within the multivariate framework model in gulf cooperation council gcc countries a panel gdp model is constructed taking the period of 1980 2012 the result revealed that natural gas energy consumption is cointegrated with gdp growth in the investigated countries in addition based on the panel dynamic ordinary least square dols and the fully modified ordinary least square fmols this study concluded that the natural gas energy consumption affects the gcc s countries gdp growth positively in the long run furthermore the results from the granger causality test revealed bidirectional causality between natural gas energy consumption and gdp growth which confirms the feedback hypothesis from the outcome of this research a number of policy implications were provided for the gcc countries

the debt equity choice when firms adjust their capital structures they tend to move toward a target debt ratio that is consistent with theories based on tradeoffs between the costs and benefits of debt in contrast to previous empirical work out tests explicitly account for the fact that firms may face impediments to movements toward their target ratio and that the target ratio may change over time as the firm s profitability and stock price change a separate analysis of the size of the issue and repurchase transactions suggests that the deviation between the actual and the target ratios plays a more important role in the repurchase decision than in the issuance decision

electricity consumption and economic growth in the gcc countries panel data analysis applying recent advances in panel data analysis we investigate the relationship between electricity consumption and economic growth in the gcc countries using annual data from 1975 to 2012 within a framework which takes into consideration dynamics heterogeneity and cross sectional dependence in the panel we show that the results obtained from using the pmge demeaned pmg amg mge and dfe models indicate a long run equilibrium relationship between electricity consumption and economic growth in order to determine the appropriate model and decide the preferred estimator the hausman test was performed the pmge model emerged as the most efficient of the three estimators also the results obtained revealed a bi directional causality between economic growth and electricity consumption in these countries which supports the feedback hypothesis as a result this implies that if these countries adopt or implement any energy or electricity conservation policies this may have a negative impact on its economic growth

was privateering plunder efficient abstract this paper argues that when contracts between enemies are enforceable and transaction costs are low plunderers and their victims benefit from trade that facilitates the former s ability to plunder the latter coasean plunder contracts transform part of plunder s social costs into private benefits for plunderers and their victims a significant portion of the wealth that plunder would otherwise destroy is preserved instead the result is more efficient plunder to investigate our hypothesis we consider maritime marauding in the 18th and 19th centuries privateers developed a system of ransom and parole founded on coasean plunder contracts with victim merchantmen

corporate control and the choice of investment financing the case of corporate acquisitions we test the proposition that corporate control considerations motivate the means of investment financing cash and debt or stock corporate insiders who value control will prefer financing investments by cash or debt rather than by issuing new stock which dilutes their holdings and increases the risk of losing control our empirical results support this hypothesis in corporate acquisitions the larger the managerial ownership fraction of the acquiring firm the more likely the use of cash financing also the previously observed negative bidders abnormal returns associated with stock financing are mainly in acquisitions made by firms with low managerial ownership do firms have systematic preferences for the means of financing investments in modigliani and miller s 1958 m m s perfect market no tax world the means by which investments are financed are irrelevant for the total value of the firm miller 1977 extended this irrelevance proposition to a case where taxes exist however casual observation suggests that firms are not indifferent to the means of financing for example many firms prefer to finance investments from internal sources or by debt rather than by issuing new equity an explanation for such systematic financing preferences and the consequent capital structure of firms is therefore called for indeed a number of such explanations have been advanced for example deangelo and masulis 1980 showed that in miller s 1977 framework the means of financing is not irrelevant if firms have different expected marginal effective tax rates due to differences in fixed charges it has also been argued that financing preferences may result from agency costs associated with debt e g barnea haugen and senbet 1981 or from asymmetry of information between managers and outside investors myers and majluf 1984 recently harris and raviv 1988 and stulz 1988 advanced a new argument for the existence of financing preferences that centers around managers incentive to maintain control over the corporation specifically by increasing debt and using the proceeds to retire equity held by the public owners managers increase the probability of maintaining control and reaping the benefits associated with it since the substitution of debt for outsiders equity decreases the fraction of

estimating the environment kuznets curve hypothesis evidence from latin america and the caribbean countries this study explores the effect of economic growth gdp renewable energy consumption re and financial development fd on co2 emission co2 in latin america and caribbean countries to achieve this goal a panel co2 model was built over the period 1980 2010 the kao cointegration test results revealed that the variables are cointegrated the fully modified ols fmols results indicated an inverted u shape relationship between co2 and gdp thus confirming the environmental kuznets curve hypothesis furthermore fmols results also revealed that fd can improve environmental quality by its negative long run effect on co2 however re has no long run effect on co2 indicating that the re does not contribute to co2 reduction the vecm granger causality results revealed feedback causality between gdp re fd and co2 in both short and long run additionally granger causality results also revealed that re gdp and fd can be a good solution to reduce environmental damage since they have a causal effect on co2 this study shows the investigated countries should increase their banking loans on green energy energy efficiency and energy saving projects to reduce environmental damage in addition the above recommendation can increase the contribution of renewable energy in reducing environmental damage

electricity consumption and economic growth nexus in portugal using cointegration and causality approaches the aim of this paper is to re examine the relationship between electricity consumption economic growth and employment in portugal using the cointegration and granger causality frameworks this study covers the sample period from 1971 to 2009 we examine the presence of a long run equilibrium relationship using the bounds testing approach to cointegration within the unrestricted error correction model uecm moreover we examine the direction of causality between electricity consumption economic growth and employment in portugal using the granger causality test within the vector error correction model vecm as a summary of the empirical findings we find that electricity consumption economic growth and employment in portugal are cointegrated and there is bi directional granger causality between the three variables in the long run with the exception of the granger causality between electricity consumption and economic growth the rest of the variables are also bi directional granger causality in the short run furthermore we find that there is unidirectional granger causality running from economic growth to electricity consumption but no evidence of reversal causality

evidence on the impact of the agency costs of debt on corporate debt policy in the last several years there has been increased theoretical emphasis on the agent principal problem as it applies to corporate finance this paper is an attempt to empirically test for the presence of the agency costs and their relation to the debt policy of corporations we find that firms with higher insider ownership have greater debt ratios than firms with lower insider ownership which may be explained by the agency costs of debt and or the agency costs of equity other regression results tend to confirm the theoretically optimal relationships put forth by myers we find that high growth firms use less debt rather than more debt high operating risk firms use more debt rather than less debt and firm size appears to be uncorrelated to the level of debt

small firm growth access to capital markets and financial structure review of issues and an empirical investigation this article investigates the financial structure of small firms with an emphasis on growth and access to capital markets neo classical economic life cycle pecking order and agency theory perspectives are reviewed in order to formulate testable propositions concerning levels of long term short term and total debt and liquidity up to date financial data were collected from the u k private database for a large sample comprising of both listed and unlisted small firms regression results indicate significant relationships between financial structure and profitability asset structure size age and stock market flotation but not growth except when rapid and combined with lack of stock market flotation analysis of stock market flotation as an interactive dummy reveals major differences between listed and unlisted small firms the results indicate that the variety of financial structures observed in practice may reflect rational trade offs of various costs on the part of small firm owner managers but that the over reliance on internally available funds and the importance of collateral in the case of unlisted small firms are likely to be major constraints on economic growth

pollution energy use gdp and trade estimating the long run relationship for vietnam abstractsince the beginning of economic reform in the 1980s and in particular with its openness to international trade accelerating since the 1990s the vietnamese economy has registered significant growth at the same time energy consumption and the level of pollution in vietnam has also increased this article aims to focus on the link between openness to trade and pollution in vietnam due to lack of data very few existing studies have focused on vietnam using annual data from1980 to 2011 and employing the bounds testing approach to cointegration based on an autoregressive distributed lagged ardl model we find that there is a statistically significant long run relationship amongst pollution openness to trade energy consumption and real national income in vietnam this conclusion continues to hold when the possibility of a structural break in the relationship is allowed for using the gregory hansen approach to cointegration analysis of the cointegration relationship suggests that in respons

endogenous destruction in conflict theory and extensions this article develops a general equilibrium model of conflict to characterize the implications of endogenous destruction for bargaining and fighting specifically we consider the scenario where two contending parties engage in bargaining to avoid fighting when there are direct costs e g arms buildups and indirect costs e g destruction to consumable resources of conflict without imposing specific functional form restrictions on conflict production and destruction technologies we show their interactions in determining an optimal decision between fighting and bargaining we find that under the shadow of conflict bargaining is costly as the contending parties always allocate more resources to arming for guarding settlement through bargaining than in the event of fighting in contrast to conventional thinking that bargaining is pareto superior over fighting we show conditions under which fighting dominates bargaining as the nash equilibrium choice the positive analysis may help explain the general causes of fighting without resorting to the assumption of incomplete information or misperceptions jel d74 h56 c7

models of energy use putty putty versus putty clay energy use is inelastic in time series data but elastic in international cross section data two models of energy use reproduce these elasticities a putty putty model with adjustment costs developed by pindyck and rotemberg 1983 and a putty clay model in the pindyck rotemberg model capital and energy are highly complementary in both the short run and the long run in the putty clay model capital and energy are complementary in the short run but substitutable in the long run we highlight the differences in the cross section implications of the models by considering the effect of an energy tax on output in both models in the putty putty model an energy tax that doubles the price of energy leads to a fall in output in the long run of 33 in contrast the same tax in the putty clay model leads to a fall in output of only 5 3

dynamics of electricity consumption oil price and economic growth global perspective this study uses the data from 157 countries from 1960 to 2014 to analyze the relationship between economic growth electricity consumption oil prices capital and labor the economic growth of developing countries with industrial infrastructure has a more significant association with electricity consumption than oil prices we use oil prices and electricity consumption jointly to study highly predictive observations for economic growth the data are categorized by income oecd and regional levels the panel cointegration long run parameter estimation and pool mean group tests are used to analyze the cointegration and short run and long run relationships between the variables the empirical results indicate the presence of cointegration between the variables the presence of feedback effects between electricity consumption and economic growth oil prices and economic growth is valid these findings confirm that in spite of the oil prices developing countries rely heavily on electricity consumption for economic growth in the short run growth and feedback effects suggest that more vigorous electricity policies should be implemented to attain sustainable economic growth for the long term

are energy conservation policies effective without harming economic growth in the gulf cooperation council countries abstract this study explores the fossil fuels electricity consumption growth of the gross domestic product gdp relationship in the six gulf cooperation council gcc countries for the period 1980 2012 the aim of this study is to examine whether energy conservation policies are appropriate for these countries to reduce their high levels of electricity consumption the autoregressive distributed lag ardl and the toda yamamoto dolado lutkepohl tydl methodologies were employed to investigate this relationship the ardl results revealed that fossil fuels electricity consumption has a long run positive effect on gdp growth in the gcc countries however the tydl granger causality revealed different causality relationships among the countries a bi directional causality was found between fossil fuels electricity consumption and gdp growth in bahrain and the united arab emirates uae while one way causality from fossil fuels electricity consumption to gdp growth was found in oman and qatar on the other hand no causality was concluded between the variables in kuwait and saudi arabia from the results it is clear that energy conservation is not an ideal policy for the bahrain uae oman and qatar because it will have a negative consequence on their output however this policy can be implemented in kuwait and saudi arabia since it will not harm their output

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

estimation of residential electricity demand in hong kong under electricity charge subsidies abstract over the past decade the hong kong hk government provided electricity charges subsidies for residential accounts to alleviate the burden of inflation and later the burden of economic downturn in this study we estimate an econometric model of residential electricity demand and test the existence of a stable long run relationship for the period 1980 2016 while accounting for the relief measures set out by the hk government since 2008 empirical results suggest that there exists a long run relationship among residential electricity consumption electricity price income per capita and weather variables temperature or cooling degree days in the absence of electricity charge subsidies the demand is found to be both price and income inelastic on the other hand hk s residential electricity consumers are unresponsive to price and income changes when electricity subsidies are in place following its new carbon reduction plan hk is gradually phasing out coal for electricity generation to replace it mainly with natural gas our results suggest that new residential electricity charge subsidies can lessen the effectiveness of6 climate policies aimed at reducing electricity consumption through increases in the electricity price

energy growth conundrum in energy exporting and importing countries evidence from heterogeneous panel methods robust to cross sectional dependence abstract this article uses the panel methods for energy exporting and importing countries that discuss the heterogeneity and cross sectional dependence in investigating the linkages between energy consumption and economic growth the findings of the study suggest that the energy consumption is an important input not only in the energy importing but also in energy exporting countries furthermore the results of the present paper suggest that the policy options should be different for the different countries in the back drop of heterogeneous slope coefficients

anarchy and its breakdown anarchy defined as a system in which participants can seize and defend resources without regulation from above is not chaos but rather a spontaneous order however anarchy is fragile and may dissolve either into formless amorphy or into a more organized system such as hierarchy under anarchy each contestant balances between productive exploitation of the current resource base and fighting to acquire or defend resources anarchy is sustainable only when there are strongly diminishing returns to fighting effort the decisiveness parameter is sufficiently low and incomes exceed the viability minimum these considerations explain many features of animal and human conflict

output and substitution elasticities of energy and implications for renewable energy expansion in the ecowas region abstract this study estimates output and substitution elasticities of renewable energy and nonrenewable energy for the economic community of west african states ecowas and discusses implications for expanding the former the results show that nonrenewable energy promises greater benefits for ecowas economic transition with output elasticities averaging between 0 052 0 579 and 0 055 to 0 223 for nonrenewable energy and renewable energy respectively overall estimated technological progress is low 0 5 to 2 6 the bulk coming from input efficiency substitution elasticities 0 02 0 94 suggest potential for switching towards renewable energy notwithstanding scale economics and sitting problems inherent in renewable power generation challenge the opportunities for energy substitution a sustainable policy solution therefore appears to be one favoring scaled and efficient electricity generation from fossil energy in the short run with a gradual switch towards renewable power in the long run in general the applied model provides insights that energy efficiency enhances sustainable growth by propelling technological advancement especially when technical change is scale biased and factor augmenting the study also provides insights that impacts of exogenous shocks to inputs are temporary and hence do not jeopardize efforts aimed at scaling output through increased and efficient use of labor capital and energy especially nonrenewable energy

environmental kuznets curve for carbon emissions in pakistan an empirical investigation this study investigates the relationship between carbon emissions income energy consumption and foreign trade in pakistan for the period 1972 2008 by employing the johansen method of cointegration the study finds that there is a quadratic long run relationship between carbon emissions and income confirming the existence of environmental kuznets curve for pakistan moreover both energy consumption and foreign trade are found to have positive effects on emissions the short run results have however denied the existence of the environmental kuznets curve the short run results are unique to the existing literature in the sense that none of the long run determinants of emissions is significant the contradictory results of short and long run give policy makers the opportunity to formulate different types of growth policies for the two terms taking environmental issues into consideration in addition the uni directional causality from growth to energy consumption suggests that the policy makers should not only focus on forecasting future demand for energy with different growth scenarios but also on obtaining the least cost energy furthermore the absence of causality from emissions to growth suggests that pakistan can curb its carbon emissions without disturbing its economic growth

can african countries efficiently build their economies on renewable energy abstract the translog production model is estimated to provide insights on the effectiveness of renewable energy for africa the analysis shows that capital labor renewable energy and nonrenewable energy drive output in african countries with renewable energy being a higher driver of growth than the conventional fossil fuels over the sample period this finding is reflective of the fact that renewable sources like wind hydro and solar account for a greater share of power generation in most african countries output elasticities computed for both energy types reaffirm the results and suggest that eastern and central african countries are more renewable energy dependent than the other three regions in addition technological progress is driven mainly by the efficiency with which various factors and energy inputs are used while africa has great potential of facing out conventional fossil energy the discussion provided in this study suggests that such transition is limited in practice due to issues of scale economics and sitting problems

electricity consumption oil price and economic growth global perspective abstract the study uses the panel data of 210 countries over the period 1960 2014 to analyze the empirical relationship between economic growth electricity consumption oil price gross fixed capital formation and population while the current literature on the topic focus largely on relationship between oil consumption and economic growth while only a few presented the research studying relationship between electricity and economic growth we used oil price and electricity consumption jointly to study the highly predictive observer for economic growth furthermore the data is categorized into income oecd regional level renewable energy consumption level and oil export import countries pedroni panel cointegration fully modified ols and panel vector error correction test apply to analyze the cointegration short run and the long run relationship between the variables the results of full panel confirm a bidirectional relationship between electricity consumption and gdp oil price and gdp fixed capital formation population and gdp moreover the results confirm that countries using non renewable sources for electricity generating such as through coal and oil the electricity consumption of these countries exhibit a negative relationship with the economic growth furthermore the finding varies across income oecd and regional renewable energy consumption level

comparing bargaining solutions in the shadow of conflict how norms against threats can have real effects abstract in many economic environments agents make costly and irreversible investments in guns that may enhance their respective threat payoffs but also shrink the utility possibilities set in such settings with variable threats and a variable utility possibilities set it becomes possible to rank different bargaining solutions in terms of efficiency we compare bargaining solutions within a class in which the influence of the threat point on the bargaining outcome varies across solutions under symmetry we find that the solution in which the threat point is least influential the equal sacrifice solution pareto dominates the other solutions since the equal sacrifice solution puts the least weight on the threat point norms against threats that can be seen in many seemingly rhetorical pronouncements in adversarial relations can mitigate some of the costs of conflict and therefore have efficiency enhancing effects journal of economic literature classification numbers c72 c78 d30 d70 d72 k42

energy consumption and economic growth new evidence from meta analysis abstract the causal relationships between energy consumption and economic growth have given rise to much discussion but remain controversial alternative data sets based on different time spans countries energy policies and econometric approaches result in diverse outcomes a meta analysis using a multinomial logit model with 174 samples governing the relationships between gdp and energy consumption is applied here to investigate the major factors that affect these controversial outcomes the empirical results have demonstrated how the time spans subject selections including gdp and energy consumption econometric models and tools for greenhouse gases emission reduction characteristics significantly affect these controversial outcomes

the costs of conflict a choice theoretic equilibrium analysis in models of destructive armed conflict it is standard to account for the endogeneity of arming allocations made by incumbent government and rebel parties indeed standard contest theoretic microeconomic models of behavior recognize that allocations change with shifts in marginal benefit or marginal cost taking governments and rebels as responsive to such shifts the present study applies standard contest theoretic equilibrium analysis to the smith et al 2014 model of conflict and cooperation this alternative solution methodology yields starkly different results within the present analysis there does not exist greater scope for cooperation given endogenously destructive arming rather than exogenously destructive arming

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

linear and nonlinear causality between sectoral electricity consumption and economic growth evidence from taiwan this study investigates the linear and nonlinear causality between the total electricity consumption tec and real gross domestic production rgdp unlike previous literature we solve the undetermined relation between rgdp and electricity consumption by classifying tec into industrial sector consumption isc and residential sector consumption rsc as well as investigating how tec isc and rsc influence taiwan s rgdp by using the granger s linear causality test it is shown that i there is a bidirectional causality among tec isc and rgdp but a neutrality between rsc and rgdp with regard to the linear causality and ii there is still a bidirectional causality between tec and rgdp but a unidirectional causality between rsc and rgdp with regard to the nonlinear causality on the basis of i and ii we suggest that the electricity policy formulators loosen the restriction on isc and limit rsc in order to achieve the goal of economic growth

energy conservation policies growth and trade performance evidence of feedback hypothesis in pakistan this study investigates the relationship between energy consumption and trade openness in pakistan by using the annual time series data for the period of 1973 2011 our main results show i the presence of long run link between energy consumption and trade performance ii positive impact of gross domestic product exports and imports on energy consumption iii bidirectional causal relationship between exports and energy consumption and also be tween imports and energy demand and iv bidirectional causality between gross domestic product and energy consumption points to the presence of feedback hypothesis in pakistan we therefore note that energy conservation policies will reduce the trade performance which in turn leads to the decline in economic growth in pakistan the present study may guide policymakers in formulating a conclusive energy and trade policies for sustainable growth for long span of time

electricity consumption and economic growth across australian states and territories this study investigates the long run and short run dynamics between electricity consumption along with traditional inputs such as labour and capital on economic output for a panel of seven austra

examining the bi directional long run relationship between renewable energy consumption and gdp growth abstract the bi directional long run relationship between renewable energy consumption and gdp growth has been investigated in high income upper middle income lower middle income and high income countries to achieve this goal the fully modified ols was utilized the results revealed that 79 of the countries have a positive bi directional long run relationship between renewable energy consumption and gdp growth this represents the feedback hypothesis on the other hand 19 of the countries showed no long run relationship between the variables this represents the neutrality hypothesis besides 2 of the countries showed a one way long run relationship from gdp growth to renewable energy consumption confirming the conservation hypothesis and from renewable energy consumption and gdp growth representing the growth hypothesis despite the mixed results across countries it has been proved that the more persistent and significant the bi directional long run relationship between the variables is the higher the income countries are

re investigating the electricity consumption and economic growth nexus in portugal in the previous decades a number of studies have been conducted to analyse the causal relationship between electricity consumption and economic growth in the portuguese economy however the evidence remains controversial because the previous studies do not provide clear causality evidence this might be attributed to the omitted variables bias because most previous studies only focus on the relationship between electricity consumption and economic growth in a bi variate model this paper attempts to re investigate the relationship between electricity consumption and economic growth in portugal using a multivariate model based on the bounds testing approach to cointegration and the granger causality test within the vector error correction model vecm our empirical results confirm the presence of cointegration among the variables moreover there is evidence of bi directional causality between electricity consumption and economic growth in the short and long run this suggests that energy is an important source of economic growth in portugal therefore energy conservation policies should not be implemented because it would deteriorate the process of economic growth and development of the portuguese economy

electricity consumption and economic growth in nigeria a revisit of the energy growth debate abstract this paper examines the dynamic causal linkages between electricity consumption and economic growth in nigeria within a trivariate vecm for the period 1971 2011 the paper obviates the variable omission bias and the use of cross sectional techniques that characterise most existing studies the results show that there is a distinct causal flow from electricity consumption to economic growth both in the short run and in the long run this finding supports the electricity led growth hypothesis that has been conjectured in the literature the paper urges policy makers in nigeria to implement policies which enhance the generation and consumption of electricity in order to engineer economic growth appropriate monetary policies must also be put in place in order to moderate inflation thus enhancing growth

a dynamic equilibrium of electricity consumption and gdp in hong kong an empirical investigation abstract public debates on electricity policy in hong kong focus on the regulation regime but seldom discuss the macroeconomic impact in this paper we use the novel dataset on electricity consumption and report the following findings 1 there is a long run equilibrium relationship between real gdp and electricity consumption 2 a one way causal effect exists from electricity consumption to real gdp 3 a significant adjustment process occurs when equilibrium is interrupted 4 there exists possible structural change in the relationship between electricity consumption and economic activities in 1990s

conflict settlement and the shadow of the future abstract we examine a conflictual setting in which adversaries cannot contract on an enforcement variable arms and where the future strategic positions of adversaries are very different when there is open conflict than when there is settlement we show that as the future becomes more important in this setting open conflict becomes more likely than settlement we demonstrate the theoretical robustness of this finding and test it in a laboratory experiment as predicted we find that subjects are more likely to engage in destructive conflict as the future becomes more important

bargaining and conflict with up front investments how power asymmetries matter abstract we examine settings such as litigation labor relations or arming and war in which players first make non contractible up front investments to improve their bargaining position and gain advantage for possible future conflict bargaining is efficient ex post but we show that a player may prefer conflict ex ante if there are sufficient asymmetries in strength there are two sources of this finding first up front investments are more dissimilar between players under conflict and they are lower than under bargaining when one player is much stronger than the other second the probability of the stronger player winning in conflict is higher than the share received under nash bargaining we thus provide a rationale for conflict to occur under complete information that does not depend on long term commitment problems greater balance in institutional support for different sides is more likely to maintain peace and settlements

war and conflict in economics theories applications and recent trends we review the main economic models of war and conflict these models vary in details but their implications are qualitatively consistent highlighting key commonalities across a variety of conflict settings recent empirical literature employing both laboratory and field data in many cases confirms the basic implications of conflict theory however this literature also presents important challenges to the way economists traditionally model conflict we finish our review by suggesting ways to address these challenges

electricity consumption from renewable and non renewable sources and economic growth evidence from latin american countries abstract this study explores the effect of renewable and non renewable electricity consumption on economic growth in 18 latin american countries to achieve the goal of this study a panel gross domestic product gdp model was constructed taking the period 1980 2010 into account from the pedroni cointegration test results it was found that renewable electricity consumption non renewable electricity consumption labor gross fixed capital formation and total trade are cointegrated moreover the panel dynamic ordinary least squares dols test results revealed that all above the mentioned variables have a long run positive effect on gdp growth in the investigated countries the vector error correction vec granger causality model results revealed the existence of feedback causality between the variables the results of the study indicated that renewable electricity consumption is more significant than non renewable electricity consumption in promoting economic growth in the investigated countries in the long run and the short run based on the results of this study it is recommended that the investigated countries should increase their investment on renewable energy projects to increase the role of electricity consumption from renewable sources in addition it is essential that these countries should reduce their non renewable electricity consumption by increasing their energy efficiency and implementing energy saving projects by applying these recommendations these countries would be able to mitigate global warming and reduce their dependency on fossil fuel to increase their energy security

anarchy in the laboratory and the role of the state abstract a recent literature on the economics of conflict provides conditions under which groups of individuals divide up between producers and predators an anarchic equilibrium as well as conditions under which a government agent is empowered to make collective action choices that can completely deter predation we test these theoretical predictions in a laboratory experiment in the absence of a government agent groups of subjects choose actions consistent with the anarchic equilibrium the introduction of a government agent charged with maximizing the consumption of producers enables subjects to achieve nearly perfect coordination on the pareto superior equilibrium where all individuals choose to be producers

balance of power and the propensity of conflict we study the role of an imbalance in fighting strengths when players bargain in the shadow of conflict our experimental results suggest in a simple bargaining game with an exogenous mediation proposal the likelihood of conflict is independent of the balance of power if bargaining involves endogenous demand choices however the likelihood of conflict is higher if power is more imbalanced even though endogenous bargaining outcomes reflect the players unequal fighting strengths strategic uncertainty causes outcomes to be most efficient when power is balanced in turn the importance of exogenous mediation proposals depends on the balance of power

an international literature survey on energy economic growth nexus evidence from country specific studies in this paper an extensive review of the rapidly growing in the literature on the nexus between economic growth and four types of energy consumption total energy consumption electricity consumption nuclear consumption and renewable consumption the various hypotheses associated with the causal interaction between these variables along with a survey of the empirical literature are also discussed the survey focuses on country coverage periods modeling techniques and empirical conclusions a general observation from these studies that results are found to be sensitive to methodology and type of energy considered the empirical results for the specific countries surveyed show that i for energy consumption growth nexus 29 supported the growth hypothesis 27 the feedback hypothesis 23 the conservation hypothesis and 21 the neutrality hypothesis ii for the electricity consumption growth nexus 40 supported the growth hypothesis 33 the feedback hypothesis and 27 conservation hypothesis iii for the nuclear consumption growth nexus 60 supported the neutrality hypothesis and 40 the growth hypothesis and iv for the renewable consumption growth nexus 40 supported the neutrality hypothesis 40 the conservation hypothesis and 20 the growth hypothesis these mixed results may be attributed to the different used data selected variables and econometric approaches undertaken

literature survey on the relationships between energy environment and economic growth abstract the aim of this study is to exhibit an exhaustive survey which is related to the great flight of the literature of energy environment growth nexus at the individual and regional scale studies covering the period from 1978 to 2014 the survey takes into consideration the sample country region etc periods covering econometric strategies and conclusions our survey is based on the causality direction among i the energy use variables electricity nuclear renewable and non renewable and output growth ii between economic growth and environment and between the three variables at the same time globally these surveys provide paradoxical and not conclusive results which energy consumption can boost economic growth through the productivity enhancement and it can boost also the environmental damages through the enhancement of pollutant emissions our survey sheds more the lights on the energy environment growth literature by giving an extensive listing 1978 2014 of these causal linkages among the energy use variables environment and economic growth for both individual and collective cases there is a unanimous consensus about the importance of dealing with such dynamic relationship which is seems to be a cornerstone element in setting any ambition strategies energy ecological and economics

the hydroelectricity consumption and economic growth in asian countries evidence using an asymmetric cointegration approach this study examines the four commonly tested hypotheses in hydroelectricity consumption economic growth literature for 12 asian countries our results from a recently developed hidden cointegrati

economic growth urbanization and energy consumption a provincial level analysis of china abstract as the largest developing country with fast paced economic growth china s development has been characterized by a high degree of energy consumption high level of heavy industry international trade and urbanization progress in this study we extend the current literature by incorporating urbanization energy consumption and international trade into a production function using a panel data set model over the period from 2001 to 2012 the results show that urbanization and capital are the major contributors to china s economic growth meanwhile there exists a u shaped relationship between urbanization and economic growth that heavy industry exerts a significant negative effect on economic growth using system generalized methods of moments gmm sys estimation methods and the relationship between international trade and economic growth is mixed and no consistent results support the conclusion that the international trade promotes economic growth adjusting the industry and trade structure in economic growth is the priority for the policy makers

trivariate causality between economic growth urbanisation and electricity consumption in angola cointegration and causality analysis abstract this paper investigates the causal relationship between economic growth urbanisation and electricity consumption in the case of angola while utilizing the data over the period of 1971 2009 we have applied lee and strazicich 2003 the review of economics and statistics 63 1082 1089 2004 working paper department of economics appalachian state university unit root tests to examine the stationarity properties of the series using the gregory hansen structural break cointegration procedure as a complement we employ the ardl bounds test to investigate long run relationships the vecm granger causality test is subsequently used to examine the direction of causality between economic growth urbanisation and electricity consumption our results indicate the existence of long run relationships we further observe evidence in favour of bidirectional causality between electricity consumption and economic growth the feedback hypothesis is also found between urbanisation and economic growth urbanisation and electricity consumption granger cause each other we conclude that angola is energy dependent country consequently the relevant authorities should boost electricity production as one of the means of achieving sustainable economic development in the long run

financial capacity and output fluctuations in an economy with multi period financial relationships this paper motivates a financial propagation mechanism in the context of an intertemporal production economy with asymmetric information and with borrowers and lenders who enter multi period financial relationships a key feature is that aggregate output and borrowers financial capacity the maximum overhang of past debt they may feasibly carry are determined jointly much in the spirit of gurley and shaw 1955 expectations of future economic conditions govern financial capacity which in turn may constrain current production especially in bad times a small but persistent shift in aggregate conditions may have a large impact on financial capacity making the framework capable of motivating large endogenous fluctuations in financial constraints understanding how small disturbances can induce large output fluctuations is an on going quest in macroeconomics this paper develops a simple framework in which shifts in aggregate economic fundamentals are amplified through their impact on financial conditions a distinguishing feature is that output and borrowers financial capacity the maximum overhang of past debt they may feasibly carry are determined jointly much in the spirit of gurley and shaw 1955 expectations of future economic conditions govern financial capacity and financial capacity may constrain current production especially in bad times a number of recent papers have resurrected the view that financial factors may play a part in propagating business fluctuations the underlying theories exploit the idea that with asymmetric information between borrowers and lenders agency costs may drive the price of uncollateralized external funds above the price of internal funds in this kind of setting a borrower s financial position is a key determinant of the terms of credit she faces in the aggregate swings in borrower balance sheets over the cycle amplify fluctuations in investment and output essentially by inducing counter cyclical movements in the required premium for external finance this simple mechanism is broadly consistent with informal descriptions of how financial and real variables interacted in the great depression bernanke 1983 and in the postwar business cycles eckstein and sinai 1986 in addition numerous recent panel data studies beginning with fazzari hubbard and peterson 1988 support the notion of a financial investment accelerator mechanism

a meta analysis investigation of the direction of the energy gdp causal relationship implications for the growth degrowth dialogue abstract the complex relation between energy use and the economic process has long attracted attention issues such as the scarcity of energy resources energy theory of value degrowth and a growth approaches are closely related to the relationship between energy and development the present study traces the implications of the energy gdp causality dialogue for the context of the growth degrowth debate where the energy development link plays a decisive role in that context the present research investigates the possible existence of a fundamental macro direction of causality between energy use and economic growth that is not influenced by study specific characteristics and events towards this objective we perform a meta analysis that takes into account 158 studies on causality between energy and gdp covering the period 1978 2011 this is the first time to our knowledge that meta analysis has been applied to investigate the direction of the energy and gdp causal relationship the meta analysis results neither support the existence of a fundamental macro direction nor the so called neutrality hypothesis e gdp in the causal relationship between energy consumption and economic growth

asymmetries in the dynamic interrelationship between energy consumption and economic growth evidence from turkey abstract in this study we examine possible nonlinearities in dynamic interrelationship between energy consumption and economic growth in turkey for the 1960 2010 period by using a smooth transition vector autoregressive model in order to trace the effects of one variable on another we calculate generalized impulse response functions girfs the computed impulse response functions demonstrate asymmetric effects of positive versus negative and small versus large energy consumption shocks on output growth and vice versa specifically we find that negative energy shocks have a greater effect on output growth than positive energy shocks and that big negative energy shocks affect output much more than small negative energy shocks similarly we find that positive output shock has a greater effect on energy consumption whereas negative shocks have almost no effect on energy consumption the results of this study have clear and important implications for energy economists and policymakers in turkey

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

swords or plowshares a theory of the security of claims to property this paper develops a general equilibrium model of the allocation of resources among appropriative and productive activities the model emphasizes the distinction between offensive weapons which are the instruments of predation and fortifications which provide defense against predation the analysis of this model shows how the equilibrium security of claims to property is determined the analysis focuses on the possibility of a nonaggressive equilibrium in which no resources are allocated to offensive weapons and claims to property are fully secure we also analyze the complex relation between economic welfare and the security of claims to property we find for example that a relatively poor agent could be better off in an equilibrium with less secure claims to property

energy conservation and sustainable economic growth the case of latin america and the caribbean this study examines the causal relationships among energy consumption economic growth and carbon dioxide emissions in twenty countries from latin america and the caribbean region the methodology includes the use of phillips and perron pp tests a cointegration model with vector error correction modeling vecm and vector autoregression var with granger causality the study concludes that of the twenty countries analyzed only in four of them will it be possible to implement energy conservation polices without affecting their economic growth four others are not able to consider an energy conservation policy with economic growth and the other twelve should focus on their economic growth before adopting any conservation policies energy efficiency was found in this region especially in the countries which have both cointegration and short term equilibrium

comparing energy use structures an input output decomposition analysis of large economies abstract in this paper we aim to assess how the changes in aspects of demand impact the use of energy in the developing economies of brazil china and india and the developed economies of germany the united kingdom and the united states to achieve this objective we use input output matrices for the years 1995 and 2005 by applying a structural decomposition analysis we find the following brazil is the only country where technology has a positive impact on energy germany and the united kingdom decrease their use of energy over the sample period china and the united kingdom are the only countries where the use of renewable inputs decreases and in brazil china and the united states the use of coal increases when we change the focus of our analysis from aggregated to disaggregated results these countries can be lined up differently in terms of development in relation to their wealth and energy use

energy consumption and output evidence from a panel of 14 oil exporting countries abstract we examine the long run relation and short run dynamics between energy consumption and output in a panel of 14 oil exporting countries over 1980 2007 panel unit root tests which account for common cross sectional factors fail to reject non stationarity in both variables thus we explore their long run relation and short run dynamics using three alternative panel estimation techniques dynamic fixed effect pooled and mean group estimators before and after accounting for common cross sectional factors these estimators allow for various degrees of heterogeneity in long run parameters and short run dynamics the results based on the mean group estimator with common correlated effects suggest a a stable relation between energy consumption and output b bi directional causality in both long and short run and c the robustness of the long run causality results to the inclusion of additional variables as such environmental policies designed to curtail energy may have significant long run ramifications for economic growth and policies designed to promote economic growth may have adverse environmental consequences

regulatory effects on electricity prices in hong kong abstract in hong kong electricity is supplied by two investor owned utilities china light and power company limited clp and the hongkong electric company limited hec these two utilities operate under a special regulatory arrangement known as the scheme of control which was proposed by the industry in 1964 the objective of this paper is to evaluate whether the scheme of control has fulfilled its original intention of protecting both the producer s right to serve and the consumer s right to be served our empirical results have indicated that the first scheme of control 1964 1978 had a greater effect on reducing electricity prices than the second one 1979 1992

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

the response of firms leverage to risk evidence from uk public versus nonpublic manufacturing firms this article empirically investigates the effects of macroeconomic and firm specific risk on firms leverage the analysis is carried out for a large panel of public and nonpublic uk manufacturing firms over the period 1999 2008 our investigation provides evidence that uk manufacturing firms use less short term debt during periods of high risk however the leverage of nonpublic manufacturing firms is more sensitive to firm specific risk in comparison to their public counterparts while macroeconomic risk affects both types of firms similarly our investigation also shows that firms with high liquid assets reduce their leverage more less during periods of heightened firm specific macroeconomic risk jel c23 g32

volatility and investment interpreting evidence from developing countries we uncover a significant negative correlation between various volatility measures and private investment in developing countries even when adding the standard control variables no such correlation is uncovered when the investment measure is the sum of private and public investment spending indeed public investment spending is positively correlated with some ineasures of volatility these findings suggest that the detrimental impact of volatility on investment may be easier to detect using disaggregated data we provide several possible interpretations for our findings nonlinearities in preferences or budget constraints can cause volatility to have first order negative effects on private investment
