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

the phillips curve macroeconomic policy and the welfare of canadians a review of the two competing paradigms explaining inflation and unemployment fluctuations singles out the keynesian phillips curve as the clear empirical winner over its classic competitors reestimation of the canadian phillips curve for 1957 90 identifies a sharp structural shift toward a high degree of unemployment hysteresis after 1972 the recent attempt of macropolicy to flatten the aggregate demand curve and limit supply side shock accommodation which aims at lower and more stable inflation is then shown to make unemployment higher and more unstable on average to an extent that is an increasing function of the degree of hysteresis understanding and reducing hysteresis and developing a consensus based incomes policy that has a chance of alleviating the dismal trade off should therefore to top research and policy priorities

energy growth long term relationship under structural breaks evidence from canada 17 latin american economies and the usa abstract we study the relationship and the causal link between electric power consumption epc and gross domestic product gdp both per capita for 17 countries in latin america canada and the usa considering that many of these economies underwent important economic crises in the last three decades we therefore model the epc gdp relationship through a vec specification that allows for structural breaks along with a robust testing methodology of causal links based on the concepts of weak and super exogeneity rather than granger causality evidence favorable to the growth hypothesis epc gdp is found for eight countries while data of three countries support the conservation hypothesis gdp epc for three countries evidence is favorable to the neutrality hypothesis but should be considered with caution as for the remaining five countries the evidence is not conclusive

energy consumption and economic growth nexus in tanzania an ardl bounds testing approach abstract in this paper we examine the intertemporal causal relationship between energy consumption and economic growth in tanzania during the period of 1971 2006 unlike the majority of the previous studies we employ the newly developed autoregressive distributed lag ardl bounds testing approach by pesaran et al 2001 bounds testing approaches to the analysis of level relationships journal of applied econometrics 16 289 326 to examine this linkage we also use two proxies of energy consumption namely total energy consumption per capita and electricity consumption per capita the results of the bounds test show that there is a stable long run relationship between each of the proxies of energy consumption and economic growth the results of the causality test on the other hand show that there is a unidirectional causal flow from total energy consumption to economic growth and a prima facie causal flow from electricity consumption to economic growth overall the study finds that energy consumption spurs economic growth in tanzania

electricity consumption and economic growth in south africa a trivariate causality test abstract in this paper we examine the causal relationship between electricity consumption and economic growth in south africa we incorporate the employment rate as an intermittent variable in the bivariate model between electricity consumption and economic growth thereby creating a simple trivariate causality framework our empirical results show that there is a distinct bidirectional causality between electricity consumption and economic growth in south africa in addition the results show that employment in south africa granger causes economic growth the results apply irrespective of whether the causality is estimated in the short run or in the long run formulation the study therefore recommends that policies geared towards the expansion of the electricity infrastructure should be intensified in south africa in order to cope with the increasing demand exerted by the country s strong economic growth and rapid industrialisation programme this will certainly enable the country to avoid unprecedented power outages similar to those experienced in the country in mid january 2008

co2 emissions energy consumption economic growth and financial development in gcc countries dynamic simultaneous equation models abstract this study investigates the dynamic causal relationships among carbon emissions financial development economic growth and energy consumption for gulf cooperation council gcc countries from 1980 through 2011 annual time series data and an autoregressive distributed lag ardl model are used the main contribution of this paper is that it has investigated the causes of carbon emissions by taking into account the role of financial development and economic growth in gcc countries the results suggest long run and causal relationships among carbon emissions financial development gross domestic product gdp and energy use in all gcc countries except united arab emirates uae moreover there is long run unidirectional causality running from carbon emissions to energy use in the case of saudi arabia uae and qatar furthermore a one way causal relationship from financial development to carbon emissions in the context of uae oman and kuwait is found the evidence suggests that financial systems should take into account environmental aspects in their current operations in these countries the results of this study may be of great importance for policy and decision makers in developing energy policies for gcc countries that contribute to curbing carbon emissions while preserving economic growth

energy consumption and economic development in sub sahara africa sub saharan african countries economic development is dependent on energy consumption this paper assesses total energy demand which is composed of traditional energy wood fuel and commercial energy electricity and petroleum in the central east south and west regions of sub saharan africa cross sectional time series data for 20 countries in 25 years are analyzed and the results of the study show that wood fuel accounts for 70 of energy consumption followed by petroleum with most industrial activities utilizing some form of wood fuel regression results suggest that energy demand is inversely related to the price of petroleum and industrial development but positively related to gdp population growth rate and agricultural expansion and that price elasticity is less than one the model results also show that there are regional differences in energy demand in addition the interaction of population growth rates by regions generates mixed results and there are regional differences in the use of commercial energy consumption and gdp growth the findings of this study suggest that countries must diversify their energy sources and introduce energy efficient devices and equipment at all levels of the economy to improve gdp growth rate and gdp per capita

stylized facts and stylized illusions inflation and productivity revisited recent estimates of a negative empirical relationship between inflation and the rate of growth of productivity provide a strong case for vigorous anti inflationary policy this paper tests the robustness of this evidence using long quarterly and annual datasets for four countries canada united states united kingdom west germany our results from cointegration and other time series tests show no evidence for any connection between inflation and the level of productivity we do find a strong connection between inflation and productivity growth but it is so internally inconsistent as to be incredible the best explanation is that it is accounted for entirely by statistical bias from attempting to cointegrate stationary and non stationary variables

the impact of paying interest on reserves in the presence of government deficit financing this paper reexamines the impact that paying interest on reserves has on price level indeterminacy volatility and economic well being unlike the previous literature this model includes an after tax deficit financed by assets bonds and reserves whose returns are linked i show that the number of steady state equilibria and the corresponding level of indeterminacy are equal to or greater than those arising in the no interest economy when the level of indeterminacy is the same the economic volatility is reduced by paying interest however greater indeterminacy in the interest economy results in greater volatility finally paying interest on reserves can enhance welfare jel d6 e3 e5 i introduction the issue of paying interest on reserves was introduced by friedman almost 50 years ago in a program for monetary stability friedman s original motivation was to make the 100 reserve requirement of the chicago plan more palatable to a banking system subject to only a fractional reserve system the goal of the chicago plan and the proposal to pay interest on reserves was to establish greater price level stability and to reduce excessive price level fluctuations 1 in the subsequent decades there has been considerable research regarding the implications of paying interest on reserves 2 three studies in particular sargent and wallace 1985 smith 1991 and freeman and haslag 1996 have examined in detail whether friedman s proposal would bring about the desired reductions in price level indeterminacy and volatility as well as the welfare implications of switching from a system of not paying interest on reserves to one which did 3 however these works suffered from two specific limitations first they did not equate the interest paid on reserves to returns on assets of similar risk and duration second they assumed that the government either ran a balanced budget or had a surplus by assuming that the budget was not in deficit these works sidestepped two important issues a the impact that deficit financing has on the means for financing interest payments and b the complications that arise from simultaneously attempting to finance a deficit and set the real return on reserves one of the key results of this previous literature was that how interest payments were financed was crucial to the likelihood of indeterminacy and volatility arising however if the sum of government expenditures and interest payments on bonds and reserves exceeds tax revenue then the issue of how interest payments on reserves are financed via taxes or earnings on assets is no longer relevant instead the appropriate concern is whether the government can simultaneously finance the deficit by issuing bonds or printing money link the return on reserves to other assets such as bonds and maintain sufficient returns on bonds and reserves such that both assets are desired by consumers the objective of this paper is to reexamine in the presence of an after tax deficit the impact of switching from a system where reserves earn no interest to one where they do this is accomplished in the context of a two period overlapping generations model with multiple assets and an after tax government deficit that must be financed by a combination of debt and seigniorage income the primary goal is to compare the level of economic indeterminacy economic volatility and welfare gains in an economy where interest is paid on reserves to one where reserves earn no interest more specifically this paper addresses the following three questions first in the presence of a government deficit and a return on storage that dominates all other rates of return does paying interest on reserves reduce potential indeterminacy of equilibria second under the same conditions does the amount of economic volatility increase or decrease third are there any welfare justifications for switching to a sys tem where reserves earn interest

estimates of inter fuel substitution possibilities in chinese chemical industry abstract the chemical sector is a key driver of china s remarkable growth record and accounts for about 10 of the country s gdp this has made the industry energy intensive and consequently a major contributor to greenhouse gas emissions ghg and other pollutants this study has attempted to investigate the potential for inter fuel substitution between coal oil natural gas and electricity in chinese chemical sector by employing a translog production and cost function ridge regression procedure was adopted to estimate the parameters of the function estimation results show that all energy inputs are substitutes in addition the study produces evidence that the significant role of coal in the chinese chemical fuel mix converges over time albeit slowly these results suggest that price based policies coupled with capital subsidy programs can be adopted to redirect technology use towards cleaner energy sources like electricity and natural gas hence retaining the ability to fuel the chemical sector while also mitigating ghg emissions notwithstanding one must understand that the extent to which substituting electricity for coal will be effective depends on the extent to which coal or oil is used in generating electricity the findings of this study provide general insights and underscore the importance of chinese government policies that focus on installed capacity of renewable electricity energy intensity targets as well as merger of enterprises

is renewable energy a model for powering eastern african countries transition to industrialization and urbanization abstract this study profiles a conversation on the appropriateness of renewable energy as a model for powering development in east african countries estimated output elasticities of nonrenewable energy 0 29 0 48 are by far larger than those of renewable energy 0 12 0 08 and as such highlights the relative importance of the former also the biased component of technical change shows higher technological progress for nonrenewable energy furthermore substitution elasticities are positive 0 77 0 92 suggesting huge potential for a transition towards renewable energy however inherent limitations in renewables documented in wesseh and lin 52 53 undermine the usefulness of east african countries reliance on renewable energy

energy consumption and economic growth in south africa reexamined a nonparametric testing apporach this paper is an effort to investigate claims concerning granger causality relationship from energy consumption to economic growth in south africa we adopt a nonparametric bootstrap method to reassess evidence supporting granger causality and unravel findings of long run unidirectional causality running from energy consumption to economic growth this implies that energy conservation policies will negatively impact economic growth in south africa in addition the results of this study have implications on co2 emissions in south africa given that coal accounts for about 72 of energy this suggests that energy use would have a long run effect of raising the country s co2 emission levels hence there might be a need to develop a more balanced energy structure which will include higher share of renewable energy a further monte carlo experiment performed reveals that asymptotic granger causality test suffers size distortion problem for south african data these findings provide support for use of a bootstrap methodology and also imply that the results presented in this study are likely to be more reliable

causal independence between energy consumption and economic growth in liberia evidence from a non parametric bootstrapped causality test abstract this contribution investigates causal interdependence between energy consumption and economic growth in liberia and proposes application of a bootstrap methodology to better reflect causality employment is incorporated as additional variable the study demonstrates evidence of distinct bidirectional granger causality between energy consumption and economic growth additionally the results show that employment in liberia granger causes economic growth and apply irrespective of the short run or long run evidence from a monte carlo experiment reveals that the asymptotic granger causality test suffers size distortion problem for liberian data suggesting that the bootstrap technique employed in this study is more appropriate given the empirical results implications are that energy expansion policies like energy subsidy or low energy tariff for instance would be necessary to cope with demand exerted as a result of economic growth in liberia furthermore liberia might have the performance of its employment generation on the economy partly determined by adequate energy therefore it seems fully justified that a quick shift towards energy production based on clean energy sources may significantly slow down economic growth in liberia hence the government s target to implement a long term strategy to make liberia a carbon neutral country and eventually less carbon dependent by 2050 is understandable

electricity consumption real gdp causality nexus evidence from a bootstrapped causality test for 30 oecd countries the goal of this paper is to examine any causal effects between electricity consumption and real gdp for 30 oecd countries we use a bootstrapped causality testing approach and unravel evidence in favour of electricity consumption causing real gdp in australia iceland italy the slovak republic the czech republic korea portugal and the uk the implication is that electricity conservation policies will negatively impact real gdp in these countries however for the rest of the 22 countries our findings suggest that electricity conversation policies will not affect real gdp

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

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

energy consumption fuel substitution technical change and economic growth implications for co2 mitigation in egypt abstract energy consumption propels economic growth but the level of co2 emissions associated with a fossil dominated energy structure raises concerns for the fight against climate change to draw consensus this study develops a translog causality based model in order to study causation between electricity natural gas petroleum and economic growth in egypt in addition the models results are used to estimate the substitution possibilities between various energy pairs and to subsequently test the co2 mitigation benefits arising from fuel substitution results support a bidirectional relationship between all energy types and economic growth in egypt and suggest also that these energy types are substitutes although technical progress is estimated to be a bit slow varying between 4 5 and 7 5 there appears to be substantial co2 emissions mitigation benefits from fuel substitution amounting to reductions in the range of 1 5 and 2 2 million metric tons under a 5 investment scenario and 2 5 and 4 5 million metric tons under a 10 investment scenario these results have broader implications for energy conservation policies and industrial merger policies in developing countries moreover by studying technical change insights are provided on future co2 mitigation potential driven by energy efficiency

a real options valuation of chinese wind energy technologies for power generation do benefits from the feed in tariffs outweigh costs abstract in order to assess the viability of wind energy projects in china this paper takes a real options approach by accounting for flexibility over deployment of the technology in response to a stochastic non renewable energy cost the difference between the latter and the r d enhanced cost of renewable energy operation may be thought of as a benefit from using wind on the other hand the chinese government provides feed in tariffs to encourage further adoption of wind which should be included as a cost this work thus shows that there is substantial options value to china s wind energy program which is bolstered if the cost of carbon dioxide emissions is internalized moreover by varying the rate of feed in tariffs the model may be used to show plausible ranges for the feed in tariffs which could be a useful policy insight furthermore the study hypothesizes that with the likelihood of renewable energy to replace non renewable energy wind power in china can potentially reduce co2 emissions by approximately 6 4 by 2020 comparing to the 2005 level and highlights the significant role of wind power in china s emission targets and energy security this is a relevant paper especially given the importance of a sustainable energy transition for china more generally using the real options approach from a policy perspective could provide insights about the viability of renewable energy programs and robustness of feed in tariffs rates

energy consumption prices and economic growth in three ssa countries a comparative study in this paper we examine the causal relationship between energy consumption and economic growth in three sub saharan african countries namely south africa kenya and congo drc we incorporate prices as an intermittent variable in a bivariate setting between energy consumption and economic growth thereby creating a simple trivariate framework using the ardl bounds testing procedure we find that the causality between energy consumption and economic growth varies significantly across the countries under study the results show that for south africa and kenya there is a unidirectional causal flow from energy consumption to economic growth however for congo drc it is economic growth that drives energy consumption these findings have important policy implications insofar as energy conservation policies are concerned in the case of congo drc for example the implementation of energy conservation policies may not significantly affect economic growth because the country s economy is not entirely energy dependent however for south africa and kenya there is a need for more energy supply augmentations in order to cope with the long run energy demand in the short run however the two countries should explore more efficient and cost effective sources of energy in order to address the energy dependency problem

refined oil import subsidies removal in ghana a triple win abstract in this study claims and counterclaims that fossil fuel subsidies removal yields benefits in terms of budget deficits energy efficiency and mitigation are assessed in order to do this a global computable general equilibrium cge model has been estimated to evaluate the impact of subsidies removal on imported refined oil in ghana on prices carbon dioxide co 2 emissions households demand firm s production and real gdp the simulation experiment points to evidence that subsidy removal raises prices increases the rate of co 2 emissions reduces households demand reduces aggregate output and affects various sectors differently the increased rate of co 2 emissions due to the removal of subsidies is indicative of the existence of the so called green paradox these results underscore the fact that a removal of subsidies on fossil fuels may win in some regards but fail in others a general implication from the applied model therefore is one which supports the assertion that removal of subsidies on fossil fuels removal on energy should be implemented along with policies aimed at stimulating economic activities and reducing the level of co 2 emissions especially where there is evidence of the green paradox

electricity consumption employment and real income in australia evidence from multivariate granger causality tests this paper examines the relationship between electricity consumption employment and real income in australia within a cointegration and causality framework we find that electricity consumption employment and real income are cointegrated and that in the long run employment and real income granger cause electricity consumption while in the short run there is weak unidirectional granger causality running from income to electricity consumption and from income to employment

the renewable energy and economic growth nexus in black sea and balkan countries the aim of this study is to explore the relationship between renewable energy consumption and economic growth within the framework of traditional production function for the period of 1990 2012 in 9 black sea and balkan countries for this purpose we use pedroni 1999 2004 panel cointegration pedroni 2000 2001 co integration estimate methods and dumitrescu and hurlin 2012 heterogeneous panel causality estimation techniques the study has concluded that there is a long term balance relationship between renewable energy consumption and economic growth and renewable energy consumption has a positive impact on economic growth heterogeneous panel causality analysis results support growth hypothesis in bulgaria greece macedonia russia and ukraine feedback hypothesis in albania georgia and romania neutrality hypothesis in turkey and according to the panel data set including all nine countries the results support feedback hypothesis with the findings it was concluded that there is a significant impact of renewable energy consumption on economic growth in balkan and black sea countries

monetary fiscal and reserve requirement policy in a simple monetary growth model the authors consider an otherwise conventional monetary growth model in which spatial separation and limited communication create a transactions role for currency and stochastic relocation gives rise to financial intermediaries in this framework they consider how changes in fiscal and monetary policy and in reserve requirements affect inflation capital formation and nominal interest rates there is also considerable scope for multiple equilibria the authors show how reserve requirements that never bind along actual equilibrium paths can play an important role in avoiding undesirable equilibria finally they demonstrate that changes in apparently nonbinding reserve requirements can have significant real effects coauthors are mark g guzman elisabeth huybens and bruce d smith copyright 1997 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

long run neutrality high inflation and bank insolvencies in argentina and brazil abstract using long low frequency data on money and output over 1884 1996 for argentina and over 1912 1995 for brazil it is found that money is long run neutral but not long run superneutral with regard to real output a rise in money growth is associated with a decline in output the opposite of the tobin effect the introduction of dummy variables for 1930s or to capture recent periods of financial disruption associated with bank insolvencies does not restore long run superneutrality for either country however results indicate that bank insolvency episodes have a distinct and negative influence on output

natural gas consumption and economic growth are we ready to natural gas price liberalization in iran this paper examines the relationship between natural gas consumption and economic growth in iran within a multivariate production model we also investigate the effects of natural gas price on its consumption and economic growth using a demand side model the paper employs bounds test approach to level relationship over the period of 1972 007 we find evidence of bidirectional positive relationship between natural gas consumption and economic growth in short run and long run based on the production model the findings also suggest that real gdp growth and natural gas have positive and negative impacts on gross fixed capital formation respectively employment however was found to have negative but insignificant impact on gross fixed capital formation moreover the estimation results of demand side model suggest that natural gas price has negative and significant impact on natural gas consumption only in the long run though there is insignificant impact on economic growth these results imply that the iranian government s decision for natural gas price liberalization has the adverse effects on economic growth and policy makers should be cautious in doing this policy

stagflationary effect of government bond financing in the transforming chinese economy a general equilibrium analysis abstract this paper studies how the method of government debt financing affects the macroeconomic performance of the transforming chinese economy the investigation is conducted within the context of an endogenous growth model that incorporates the major institutional features of the chinese economy using this framework we evaluate the effects on the growth rate of output and inflation if the chinese government relies more on bonds and less on money creation for budget deficit and debt repayment financing it is shown that although this policy change can reduce the growth rate of the money supply it can generate a stagflationary effect reducing the rate of output growth while raising the rate of inflation if the initial fraction of government deficit and debt repayment financed by bonds is sufficiently small and the tax rate on labor income is sufficiently low

the conduct of monetary policy with a shrinking stock of government debt this article considers the consequences for a central bank of a declining stock of government debt the model has a treasury that taxes spends and issues debt a central bank that conducts open market operations in treasury debt and banks that intermediate private savings it suggests that a sufficiently small stock of debt can put an economy on the pareto inferior side of the seigniorage laffer curve implying unnecessarily high inflation if there is also a primary budget deficit equilibrium might not exist discount window lending is a potentially desirable alternative to open market operations especially if the loans are not subsidized

quantitative modelling of electricity consumption using computational intelligence aided design abstract high electricity consumption is of concern to the world for a variety of reasons including its social economic environmental coupled impacts on well being of individuals social life and the federal energy policies this paper proposes a quantitative model to examine the long term relationship between annual electricity consumption and its major macroeconomic variables including gross domestic product electricity price efficiency economic structure and carbon dioxide emission using computational intelligence aided design ciad it develops a firefly algorithm with variable population favp to obtain the parameters of the electricity consumption model through optimising two proposed trend indices moving mean of the average precision mmap and moving mean of standard derivation mmstd the model is validated with empirical electricity consumption data in china between 1980 and 2012 based on which the error of approximations between 1980 and 2009 is 15 and the error of predictions between 2010 and 2012 is 8 5 the main contributions of this research are to develop 1 a novel quantitative model that can accurately predict the social economic and environmental coupled impacts on the annual electricity demands 2 the conceptual ciad framework 3 favp algorithm and 4 two new trend indices of mmap and mmstd the findings of this research can assist the decision makers in resolving the conflict between energy consumption growth and carbon emission reduction without dooming the economic prosperity in the long run

energy consumption and economic growth revisited in african countries abstract the aim of this paper is to provide new empirical evidence on the relationship between energy consumption and economic growth for 21 african countries over the period from 1970 to 2006 using recently developed panel cointegration and causality tests the countries are divided into two groups net energy importers and net energy exporters it is found that there exists a long run equilibrium relationship between energy consumption real gdp prices labor and capital for each group of countries as well as for the whole set of countries this result is robust to possible cross country dependence and still holds when allowing for multiple endogenous structural breaks which can differ among countries furthermore we find that decreasing energy consumption decreases growth and vice versa and that increasing energy consumption increases growth and vice versa and that this applies for both energy exporters and importers finally there is a marked difference in the cointegration relationship when country groups are considered

electricity consumption and economic growth a time series experience for 17 african countries abstract while the availability of electricity by itself is not a panacea for the economic and social problems facing africa the supply of electricity is nevertheless believed to be a necessary requirement for africa s economic and social development this paper tests the long run and causal relationship between electricity consumption per capita and real gross domestic product gdp per capita for 17 african countries for the period 1971 2001 using a newly developed cointegration test proposed by pesaran et al 2001 and using a modified version of the granger causality test due to toda and yamamoto 1995 the advantage of using these two approaches is that they both avoid the pre testing bias associated with conventional unit root and cointegration tests the empirical evidence shows that there was a long run relationship between electricity consumption per capita and real gdp per capita for only 9 countries and granger causality for only 12 countries for 6 countries there was a positive uni directional causality running from real gdp per capita to electricity consumption per capita an opposite causality for 3 countries and bi directional causality for the remaining 3 countries the result should however be interpreted with care as electricity consumption accounts for less than 4 of total energy consumption in africa and only grid supplied electricity is taken into account

electricity consumption and economic growth in burkina faso a cointegration analysis abstract this study empirically establishes the direction of causality between electricity consumption and economic growth in burkina faso for the period 1968 2003 the bounds test yields evidence of cointegration between electricity consumption gdp and capital formation when electricity consumption and gdp are used as dependent variable causality results indicate that there is no significant causal relationship between electricity consumption and investment estimates however detect in the long run a bidirectional causal relationship between electricity use and real gdp there is also evidence of a positive feedback causal relationship between gdp and capital formation burkina faso is therefore an energy dependent country it is also a country in which electricity consumption is growing with the level of income all of this shows that electricity is a significant factor in socio economic development in burkina faso as such energy policy must be implemented to ensure that electricity generates fewer potential negative impacts

productivity in the united states trends and cycles productivity growth in the us has taken a sharp downturn in recent years two experts provide a new body of comparative data on productivity since 1948 by major sector and industry the book analyzes 20 industries to highlight trends and fluctuations in productivity and to provide a better context for the discussion of policy options the authors set forth the causes of productivity advances based on growth accounting for the business economy as a whole they detail interindustry regressions with particular reference to the productivity slowdown since 1966 they look at both the traditional measure of productivity labor output per hour and the more recently developed measure of total factor productivity which takes into account capital as well as labor inputs the quarterly and annual data are used to relate changes to other basic variables such as factor prices unit costs and product prices an appendix presents data for 35 industries 42 references 8 figures 30 tables

the electricity consumption versus economic growth of the polish economy abstract the aim of this contribution is an investigation of causal interdependences between electricity consumption and gdp in poland our research was conducted for total electricity consumption as well as for the industrial consumption of electricity in order to reflect the causality between gdp and electricity consumption properly we performed our investigations in a three dimensional framework with employment chosen as an additional variable we used reliable quarterly data from the period q1 2000 q4 2009 in order to check the stability of the causalities the investigations were performed on two samples a full sample and a pre crisis i e q1 2000 q3 2008 subsample we applied both traditional methods and some recently developed econometric tools we found feedback between total electricity consumption and gdp as well as between total electricity consumption and employment we also found unidirectional causality running from industrial electricity consumption to employment and no direct causal links between industrial electricity consumption and gdp in addition all these findings were in general not seriously affected by the financial and economic crises of 2008 a significant exception is the causal effect of industrial electricity consumption on employment which was more pronounced after the crisis of 2008

interactions between energy and imports in singapore empirical evidence from conditional error correction models this study empirically tests for long run equilibrium relationship and the direction of causality between imports and energy consumption in singapore the results of the present study reveal that a long run equilibrium relationship exists between import growth and energy consumption growth in singapore by using bivariate systems imports of singapore converge to long term equilibrium levels by 79 9 percent speed of adjustment through the channel of energy growth furthermore the major finding of this study is that there are long and short term undirectional causalities that run from energy growth to import growth in singapore which denote that energy consumption in singapore is a catalyst for importing

environmental policy and double dividend in a transitional economy abstract although the environmental benefit from implementing a climate tax is usually realized the economic dividend still remains a controversial issue warranting further research this is because the impact of an environmental policy on an economy wide system will depend on factors that differ from one region to the next in this paper we develop a static cge model for liberia that is capable of analyzing both a uniform and a partial carbon tax policy under the uniform policy instituted to ensure mitigation in the range of 20 50 an economic dividend is found for energy employment and welfare in particular energy consumption increases by between 5 and 15 5 respectively interestingly under a second best policy which exempts economically strategic sectors from the tax no economic dividend is found for all three variables this time energy use declines by between 2 and 9 these suggest that a uniform environmental tax policy is a more viable option for liberia in particular as it does not only generate economic dividend for employment and welfare it also incentivizes liberia s adoption and use of renewable energy technologies in general based on the results obtained further conditions for the feasibility of a double dividend are proposed

tight money policies and inflation revisited in this paper we reconsider the link between tight money policies and inflation in the spirit of sargent and wallace s 1981 influential paper some unpleasant monetarist arithmetic a standard neoclassical model with capital bonds and return dominated currency is used the potential for tight money policies to be inflationary unpleasant arithmetic exists even when the real interest rate is below the growth rate of the economy additionally the likely observability of unpleasant arithmetic in real world economies is shown to depend crucially on the type of monetary policy rule that is used jel classification e52 e63 un autre coup d il sur la relation entre politiques monetaires restrictives et inflation ce memoire re examine la relation entre politiques monetaires restrictives et inflation dans l esprit du travail de sargent et wallace 1981 some unpleasant monetarist arithmetic les auteurs utilisent un modele neo classique standard avec capital debentures et une monnaie dont les rendements sont domines par ceux d autres reservoirs de valeur la possibilite que les politiques monetaires restrictives soient inflationnistes existe meme quand le taux d interet reel est plus petit que le taux de croissance de l economie de plus on montre que l obtention de ces resultats deplaisants dans les economies concretes depend fondamentalement du type de regle monetaire qu on utilise

the effects of inflation on economic growth lessons from latin america this paper investigates the relationship between inflation and long run growth it presents an endogenous growth model that illustrates the channels through which inflation affects growth the model highlights the effects of inflation on the productivity of capital and the rate of capital accumulation the reduction in growth is caused by a diversion of resources away from activities that lead to faster rates of growth toward activities associated with reducing the costs of inflation the negative association between inflation and growth is assessed empirically for a sample group of latin american countries this abstract was borrowed from another version of this item

is reserve ratio arithmetic more pleasant does it matter in a revenue neutral setting if the government changes the inflation tax base or the inflation tax rate we answer this question within the context of an overlapping generations model in which government bonds capital and cash reserves coexist we consider experiments that parallel those studied in sargent and wallace s unpleasant monetarist arithmetic the government uses seigniorage to service its debt choosing between changing either the money growth rate the inflation tax rate or the reserve requirement ratio the inflation tax base in the former case we obtain standard unpleasant arithmetic in the long run a permanent open market sale results in higher money growth and higher long run inflation somewhat surprisingly it turns out that for a given money growth rate lower reserve requirements fund the government s interest expense associated with the lower reserve requirements is lower long run inflation and higher welfare compared with the money growth case the broad message is that reserve ratio arithmetic can be pleasant even when money growth arithmetic is not

monetary policy arithmetic reconciling theory with evidence empirical evidence indicates that in countries with low inflation rates a permanent decrease in inflation rate either has no impact on capital stock and output superneutrality or causes them to fall moderately existing budget arithmetic models of monetary policy cannot deliver superneutrality in this paper we conduct a budget arithmetic analysis of monetary policy using a money demand specification money in the utility function that is new to this literature we find that one simple assumption about utility from money delivers superneutrality while a more general assumption delivers departures from superneutrality in the direction consistent with the evidence jel classification e60 e13

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

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

is low inflation an important condition for high growth factual evidence for the seemingly universal belief that low price inflation is necessary for high gnp growth is curiously lacking maybe even felt to be unnecessary this paper takes what is thought to be all the not very voluminous postwar factual data that are relevant and treats this data in a number of ways to find whether any convincing demonstration of the truth of this belief is possible the paper concludes that it is not c 1993 academic press inc copyright 1993 by oxford university press

pricing decisions in an experimental dynamic stochastic general equilibrium economy we construct experimental economies populated with human subjects with a structure based on a nonlinear version of the new keynesian dynamic stochastic general equilibrium dsge model we analyze the behavior of firms pricing decisions in four different experimental economies we consider how well the experimental data conform to a number of accepted empirical stylized facts pricing patterns mostly conform to these patterns most price changes are positive and inflation is strongly correlated with average magnitude but not the frequency of price changes prices are affected negatively by the productivity shock and positively by the output gap lagged real interest rate has a negative effect on prices unless human subjects choose the interest rate or firms sell perfect substitutes in the output market there is inertia in price setting firms integrate wage increases into their prices and there is evidence of adaptive behavior in price setting in our laboratory economy the hazard function for price changes however is upward sloping in contrast to most empirical studies

energy economic growth and causality in developing countries a case study of tanzania and nigeria the debate about the precise role of energy in economic development remains contentious existing empirical studies have produced varying results some have argued the complementarity between energy and other factors of production and others have indicated that energy can be substituted for other factors of production commonly these studies have focused primarily on the developed countries one explanation being that supply constraints and price rigidities render any study on factor substitutions in developing countries meaningless however the functional relationship between energy consumption and income in developing countries is constantly investigated with the use of regression techniques while such techniques are useful in empirical analysis no mechanism exists for indicating causal directions between variables this limits the scope for policy analysis and prescription the need to identify causal direction between energy consumption and income growth in developing countries is overwhelming apart from providing further insights into the role of energy in economic development it provides policy analysts with a clearer understanding of the likely impact of energy supply constraints on economic growth this article examines the causal directions between energy consumption and economic growth proxied by gdp and gnp for nigeria and tanzania the results show a simultaneous causal relationship between energy and economic growth for both countries the implication being that unless energy supply constraints are eased economic growth and development will remain elusive to these countries given similar economic characteristics and profiling the same energy scenario for other developing countries our finding supports the view that energy plays a key role in economic development

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

a new statistic and practical guidelines for nonparametric granger causality testing abstract in this paper we introduce a new nonparametric test for granger non causality which avoids the over rejection observed in the frequently used test proposed by hiemstra and jones 1994 testing for linear and nonlinear granger causality in the stock price volume relation journal of finance 49 1639 1664 after illustrating the problem by showing that rejection probabilities under the null hypothesis may tend to one as the sample size increases we study the reason behind this phenomenon analytically it turns out that the hiemstra jones test for the null of granger non causality which can be rephrased in terms of conditional independence of two vectors x and z given a third vector y is sensitive to variations in the conditional distributions of x and z that may be present under the null to overcome this problem we replace the global test statistic by an average of local conditional dependence measures by letting the bandwidth tend to zero at appropriate rates the variations in the conditional distributions are accounted for automatically based on asymptotic theory we formulate practical guidelines for choosing the bandwidth depending on the sample size we conclude with an application to historical returns and trading volumes of the standard and poor s index which indicates that the evidence for volume granger causing returns is weaker than suggested by the hiemstra jones test

does productivity growth lower inflation in korea we investigate granger causality between productivity growth and inflation in korea using quarterly data for the period 1985q1 2002q4 our results indicate unidirectional granger causality from productivity growth to inflation in light of such causality we estimate the effect of productivity and other variables on productivity according to our regression results a 1 increase in labour and total factor productivity tfp reduces consumer price index cpi inflation by 0 07 0 08 and 0 37 0 44 respectively our results also suggest that the productivity inflation nexus became stronger in korea since the asian financial crisis and that this was largely due to structural reform and technological progress

real wages inflation and labour productivity in australia this paper presents an analysis of real wages inflation and labour productivity interrelationships using cointegration granger causality and most importantly structural change tests applications of tests to australian data over the 1965 2007 period corroborate the presence of a structural break in 1985 and show that a 1 percent increase in manufacturing sector real wages led to an increase in manufacturing sector productivity of between 0 5 and 0 8 percent comparable estimates for the effect of inflation on manufacturing sector productivity have limited statistical significance granger causality test results suggest that real wages and inflation both granger cause productivity in the long run

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

does economic growth in malaysia depend on disaggregate energy abstract this study aims to investigate long run relationship between economic growth and disaggregated energy consumption in malaysia toda yamamoto t y the modified granger causality test along with annual disaggregated energy and real gdp growth data from 1971 to 2014 was used in the investigation process this paper presents several outcomes firstly this paper argues that the malaysian economy is energy dependent and sensitive to energy supply shocks secondly the usage of energy inputs in malaysian economy is found to be consumed inefficiently meaning that usage of higher energy resources does not contribute the economic growth significantly rather causes environmental pollution badly thirdly the finding indicates that economic growth and environmental pollution through spreading carbon emissions are responsive to each other in this circumstance the malaysian economy has to find a way to consume the energy inputs efficiently so that economic growth is improved while negative externality in the environment is reduced therefore the study presents significant policy implications in order to improve the energy efficiency and reduce environmental pollution

the effect of inflation and real wages on productivity new evidence from a panel of g7 countries this article examines the effect of inflation and real wages on productivity within a panel unit root and panel cointegration framework for the g7 countries over the period 1960 to 2004 the main contribution of the article is to provide panel long run estimates of the effect of inflation and real wages on productivity in the g7 countries over this period the article finds that for the panel as a whole a 1 increase in real wages generates a 0 6 increase in productivity while the effects of inflation on productivity are statistically insignificant for most of the individual countries and for the panel as a whole

renewable energy electricity development in ghana observations concerns substitution possibilities and implications for the economy abstract can ghana build its economy on renewable energy is it possible to substitute nonrenewable for renewable energy what is the impact of renewable energy on the economy of ghana these questions are relevant and worth considering as far as the renewable energy development agenda in ghana is concern using the translog production function approach this study primarily investigates whether ghana can move away from nonrenewable electricity generation to renewable power generation in particular we provide estimates for the relationship between the two energy types and output the estimates are then used to calculate the output and substitution elasticities between renewable and nonrenewable energy our findings show that while the impact of nonrenewable energy on ghana s economy is negative that of renewable energy is insignificant with output elasticities for both energy types averaging 0 139 and 1 875 respectively even though substitution elasticity suggests the possibility of moving towards a renewable power generation system this study also highlights the limitations associated with such transition citing inherent problems such as scale cost and location based on the analysis done in the context of the findings this study recommends a policy that supports an optimal energy matrix with both renewable and nonrenewable sources

carbon dioxide co2 emissions during urbanization a comparative study between china and japan as the world s largest emitter of co2 china is facing increasing domestic and international pressures on emissions mitigation considering japan s leading position in energy conservation this paper conducts a comparative study between china and japan at the urbanization stages to analyze the similarities as well as differences of influencing factors of co2 emissions results indicate that although co2 emissions in japan and china showed the similar characteristics of rigid growth during the urbanization processes significant differences exist in factors such as co2 emissions per capita energy structure and energy intensity between the two countries which are the determinants for co2 emissions growth a cointegration model is constructed to examine the long run equilibrium relationship between co2 emissions and factors including gdp urbanization level energy intensity and cement manufacture empirical results show that there is a quadratic relationship between income growth and co2 emissions granger causality test is then adopted to explore the causal relationships among the variables the future co2 emissions and emission reduction potentials in china are estimated based on scenario analysis finally japan s valuable experience of reducing energy intensity and optimizing energy structure is concluded to provide important policy implications for china s strategic low carbon planning and low carbon transition

threshold cointegration and causality relationship between energy use and growth in seven african countries abstract the paper investigates the long run and the causality relationship between energy consumption and economic growth for seven sub saharan african countries during the period 1970 2007 using the gregory and hansen 1996a 1996b testing approach to threshold cointegration we find that energy consumption is cointegrated with economic growth in cameroon cote d ivoire ghana nigeria and south africa moreover this test suggests that economic growth has a significant positive long run impact on energy consumption in these countries before 1988 and this effect becomes negative after 1988 in ghana and south africa furthermore causality tests suggest bidirectional causality between energy consumption and real gdp in cote d ivoire and unidirectional causality running from real gdp to energy usage in the case of congo and ghana

exploring the relationship between agricultural electricity consumption and output new evidence from turkish regional data abstract this study investigates the relationship between agricultural electricity consumption and agricultural output for a panel of 12 regions of turkey for the period 1995 2013 in order to reveal the possible heterogeneity between regions empirical analyses are conducted for the whole panel data and two sub groups within the panel data namely coastal regions and non coastal regions the results from several panel unit root tests indicate that electricity consumption and output are stationary process at their levels for overall panel and the two specific groups by using the ols with regional fixed effects this study finds that coefficient estimate of electricity consumption on output is statistically significant and positive for overall regions coastal regions and non coastal regions in addition the results from the dumitrescu hurlin granger causality test show that there is unidirectional causality running from agricultural output to electricity consumption for non coastal regions and there is bidirectional causality between agricultural electricity consumption and output for overall panel and coastal regions findings and policy implications are further discussed

does improved environmental quality prevent a growing economy abstract a major concern for sustainable development is how countries can lower pollution while avoiding adverse output and energy shocks since economic activities change with time we develop a dynamic applied equilibrium model to study the dynamics of co2 emissions and evaluate how the pursuit of environmental policy objectives can influence output and productivity in a surrogate country in transition under an optimal environmental policy which ensures mitigation between 38 and 50 we show that productivity projected towards the year 2075 increases slightly from between 3 8 and 6 2 to between 5 7 and 7 6 respectively the required carbon tax begins from 5 29 ton in 2020 and grows on average by 3 5 reaching up to 35 83 per ton carbon towards the year 2075 even though these tax rates ensure huge benefits for mitigation they represent marginal productivity growth and substantial output and consumption costs in other words improved environmental quality presents opportunities for multifactor productivity mfp but this productivity improvement is too marginal to offset the compliance costs of the carbon tax thereby causing output to decline hence to ensure maximum economic dividend from carbon pricing especially in transitional economies measures are required to improve the innovation benefits of carbon taxes towards levels that offset the compliance costs of environmental regulations otherwise caution should be taken by developing countries in their environmental policy designs especially when boosting consumption and economic growth is a major priority

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

the productivity inflation nexus the case of the australian mining sector this paper examines the causal links between productivity growth and two price series given by domestic inflation and the price of mineral products in australia s mining sector for the period 1968 1969 to 1997 1998 the study also uses a stochastic translog cost frontier to generate improved estimates of total factor productivity tfp growth the results indicate negative unidirectional causality running from both price series to mining productivity growth regression analysis further shows that domestic inflation has a small but adverse effect on mining productivity growth thus providing some empirical support for australia s inflation first monetary policy at least with respect to the mining sector inflation in mineral price on the other hand has a greater negative effect on mining productivity growth via mineral export growth

oil price fluctuation volatility spillover and the ghanaian equity market implication for portfolio management and hedging effectiveness abstract this study attempts to contribute to the literature on stock markets and energy prices by examining the dynamic volatility and volatility transmission between oil and ghanaian stock market returns in a multivariate setting using the recently developed var garch var agarch and dcc garch frameworks in turn the models results are used to compute and analyze the optimal weights and hedge ratios for oil stock portfolio holdings for comparison purposes and to put the paper more in the perspective of west africa the nigerian stock market is also included in the analysis our findings point to the existence of significant volatility spillover and interdependence between oil and the two stock market returns while spillover effects are stronger for nigeria the transmission of volatility is much more apparent from oil to stock than from stock to oil in the case of ghana also the study demonstrates evidence of short term predictability in oil and stock price changes through time and reveals that conditional volatility changes more rapidly as result of substantial effects of past volatility rather than past news shocks for all market returns moreover we show that there is a slightly more effective hedge in the two stock markets under the dcc garch framework our preferred model compared to the other two models although hedging effectiveness is much greater for ghana on the whole our findings for optimal hedge ratios are consistent with other studies and particularly the view that oil assets should be an integral part of a diversified portfolio of stocks and suggest that a better understanding of volatility links is crucial for portfolio management in the presence of oil price risk finally the existence of multivariate asymmetric effects and dynamic conditional correlations as revealed by the var agarch and dcc garch models make it clear that the assumptions of symmetric effects and constant conditional correlations are not supported empirically

some even more unpleasant monetarist arithmetic does monetizing a deficit always result in a higher rate of inflation than bond financing the same deficit t j sargent and n wallace 1981 produced conditions under which the answer was negative unpleasant monetarist arithmetic subsequent authors have challenged the empirical validity of these conditions the authors develop a model similar to that of sargent and wallace and modify it to allow for financial intermediation in the presence of reserve requirements unpleasant arithmetic arises even when the real rate of growth exceeds the real return on bonds moreover under empirically plausible restrictions there exists a unique equilibrium no laffer curve considerations arise

delving into liberia s energy economy technical change inter factor and inter fuel substitution abstract the industrial energy mix of liberia is dominated by petroleum products this has generated serious environmental problems contributing immensely to co 2 emissions and other pollutants in the country this study has attempted to investigate the potential for inter factor and inter fuel substitution between capital labor petroleum and electricity in liberia by employing a translog production and cost function approach ridge regression procedure has been adopted to estimate the parameters of the function due to multicollinearity in the data estimation results show that all inputs are substitutes these suggest that price based policies coupled with capital subsidy programs can be adopted to redirect technology use towards cleaner energy sources like electricity hence retaining the ability to fuel the economy while also mitigating greenhouse gas ghg emissions substitution between energy and labor and energy and capital implies that removal of price ceilings on energy in liberia would tend to reduce energy use and increase capital and labor intensiveness notwithstanding the study seems to show no evidence of convergence in relative technological progress of the four inputs implying that petroleum will continue to play a dominant role in the energy consumption mix of liberian industry while labor investment will continue to outweigh capital inputs finally the findings of this study provide general insights and underscore the importance of policies that focus on installed capacity of renewable electricity energy intensity targets as well as merger of enterprises

the saving and investment nexus for china evidence from cointegration tests the saving and investment nexus as postulated by feldstein and horioka fh 1980 is revisited the saving investment correlation for china is estimated over the periods 1952 1998 and 1952 1994 the latter culminating in a period of fixed exchange rate regime amongst the key results it is found that saving and investment are correlated for china for both the period of the fixed exchange rate and the entire sample period with high saving investment correlation the results suggest that the chinese economy is in conformity with the fh hypothesis this is a valid outcome for in china capital mobility was fairly restricted over the 1952 1994 period as indicated by the relatively low foreign direct investment

renewable energy technologies as beacon of cleaner production a real options valuation analysis for liberia abstract the importance of energy consumption for growth and development calls for improved decision support for a sustainable energy transition given africa s dependence on fossil fuels the economic and environmental savings from research development and deployment of renewable energy technologies may be substantial although the benefits of renewable energy technologies research development funding may appear to be low assuming immediate deployment the uncertainty in the non renewable energy price and the flexibility over timing makes research development program more appealing this study develops different scenarios in order to quantify benefits provided by research development funding for renewable power generation in liberia by using real options pricing approach to estimate the value of renewable energy technologies while taking into account the uncertainty of fossil fuel prices and learning by doing in renewable energy technologies the optimal solution shows that renewable energy technologies are economically attractive especially when external costs are internalized however annual research development funding is low and should be raised significantly in order to guarantee the highest possible investment incentives with minimal expenditures the study also hypothesizes that with the likelihood of renewable energy to replace non renewable energy renewable power use in liberia can potentially reduce carbon dioxide emissions by approximately 13 9 by 2015 compared to the 2008 levels the key insight provided by the real options analysis in this study is that while renewable energy may have inherent limitations such as seasonality of supply low energy content and capacity factor issues they still hold a significant amount of value which can only be detected when externalities are internalized thus underscoring the need for external costs related policies

investigating the multivariate granger causality between energy consumption economic growth and co2 emissions in ghana abstract the economy of ghana continues to witness a rising demand for energy coupled with growth in gross domestic product that follows a wavy trajectory in the midst of this economic phenomenon there is a trend of increasing greenhouse gas emissions with attendant economic health and environmental consequences this paper examines the causal interdependence between energy consumption economic growth and co 2 emissions in ghana from 1960 to 2015 by using the toda yamamoto and granger causality tests the johansen and johansen juselius cointegration approach and the autoregressive distributed lag bounds test approach are employed to test for cointegration relationship the results show that the variables are cointegrated the causality tests reveal that there is feedback granger causality between energy consumption and co 2 emissions since there is a causal link between energy consumption and economic growth with its concomitant effect on co 2 emissions any energy conservation oriented policy not derived from energy efficiency and technological progress may hurt the ghanaian economy in effect more effort should be aimed at improving energy efficiency through technological progress and investment should be made in renewable energy to reduce over reliance on fossil fuels

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

inflation taxes and the coordination of monetary and fiscal policy by use of a game of chicken in this study some of the consequences of an uncertain policy struggle game of chicken between independent taxing agencies a monetary and a fiscal authority are exam ined we show that policy uncertainty may improve upon regimes where there is no uncer tainty and one agency succeeds in implementing a low tax policy at the expense of the other agency an uncertain tax policy never dominates a fully coordinated tax policy but it can move average tax rates in the right direction in this sense the game of chicken between agencies can be beneficial and can compensate for the lack of a specific coordinating admin
