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

domestic violence a nonrandom affair in this paper we develop and estimate a model of domestic violence we extend a noncooperative model of the family to include violence as a source of gratification and an instrument for controlling behavior we estimate the model by robust methods since the violence process appears to have a heavy tailed nonnormal error distribution we find that the properties of the equilibria depend on family income for low middle income families our results indicate an equilibrium in which one person s reservation utility constraint is binding whereas for higher income families both individuals may gain from the relationship

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

energy consumption real income and temporal causality results from a multi country study based on cointegration and error correction modelling techniques abstract unlike previous studies on the causal relationship between energy consumption and economic growth this paper illustrates how the finding of cointegration i e long term equilibrium relationship between these variables may be used in testing granger causality based on the most recent johansen s multivariate cointegration tests preceded by various unit root or non stationarity tests we test for cointegration between total energy consumption and real income of six asian economies india pakistan malaysia singapore indonesia and the philippines non rejection of cointegration between variables rules out granger non causality and imples at least one way of granger causality either unidirectional or bidirectionial secondly by using a dynamic vector error correction model we then analyse the direction of granger causation and hence the within sample granger exogeneity or endogeneity of each of the variables thirdly the relative strength of the causality is gauged through the dynamic variance decomposition technique by decomposing the total impact of an unanticipated shock to each of the variables beyond the sample period into proportions attributable to shocks in the other variables including its own in the bivariate system results based on these tools of methodology indicate that while all pair wise relationships shared common univariate integrational properties only relationships for three countries india pakistan and indonesia were cointegrated for these countries temporal causality results were mixed with unidirectional causality from energy to income for india exactly the reverse for indonesia and mutual causality for pakistan the vdcs were not inconsistent with these results and provided us with an additional insight as to the relatively more dominant direction of causation in pakistan simple bivariate vector autoregressive models for the three non cointegrated systems did not indicate any direction of causality significantly in either direction

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

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

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

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

causal relationship between energy consumption and gdp revisited the case of korea 1970 1999 abstract causal relationship between energy consumption and economic growth is investigated applying a multivariate model of capital labor energy and gdp usual btu energy aggregate is substituted with a divisia aggregate in an attempt to mitigate aggregation bias to test for granger causality in the presence of cointegration among the variables we employ a vector error correction model rather than a vector autoregressive model empirical results for korea over the period 1970 1999 suggest a long run bidirectional causal relationship between energy and gdp and short run unidirectional causality running from energy to gdp the source of causation in the long run is found to be the error correction terms in both directions

energy and economic growth in the usa a multivariate approach abstract this paper examines the causal relationship between gdp and energy use for the period 1947 90 in the usa the relationship between energy use and economic growth has been examined by both biophysical and neoclassical economists in particular several studies have tested for the presence of a causal relationship in the granger sense between energy use and economic growth however these tests do not allow a direct test of the relative explanatory powers of the neoclassical and biophysical models a multivariate adaptation of the test vector autoregression var does allow such a test a var of gdp energy use capital stock and employment is estimated and granger tests for causal relationships between the variables are carried out although there is no evidence that gross energy use granger causes gdp a measure of final energy use adjusted for changing fuel composition does granger cause gdp

effects of energy consumption on per worker output a study of kenya and south africa the paper investigates the long run cointegration relationship and energy elasticities for kenya and south africa over the periods 1978 2009 and 1971 2009 respectively using the ardl procedure developed by pesaran et al 2001 with recomputed critical bounds from narayan 2005 and the solow 1956 framework extended by rao 2010 we also conduct the toda and yamamoto 1995 test for granger non causality the regression results show that short run and long run energy elasticities are 0 50 and 1 71 respectively for kenya and 0 17 and 0 34 respectively for south africa the causality results indicate a unidirectional granger causality running from capital per worker and energy per capita to output per worker for both countries moreover in kenya we detect a strong unidirectional causality a on output from joint consideration of capital stock and energy and b on capital stock from joint consideration of energy and output in south africa the joint causations are neutral hence while energy and capital stock spurs growth in both countries kenya has a greater potential to harness growth and capital productivity via joint consideration of energy with capital and output respectively

the relationship between energy and gnp further results this paper reexamines the casuality between gnp and energy consumption by using updated us data for the period 1947 1979 as a secondary contribution we investigate the causal relationship between energy consumption and employment applying sims technique we find no causal relationship between gnp and energy consumption we find further that there is a slight unidirectional flow running from employment to energy consumption economic interpretations of the empirical results are also presented

the structural pension reform in chile effects comparisons with other latin american reforms and lessons chile pioneered a structural reform in latin america that privatized its public pension system and influenced similar reforms in another nine countries twenty five years later this article evaluates the macroeconomic microeconomic and social effects of this reform in chile and the other countries in the region and extracts lessons from those experiences fiscal costs of the reform have been high and prolonged exceeded capital accumulation and had a negative impact on national savings but chile s reform has contributed to the development of capital markets employer s contributions were eliminated or reduced in half of the countries and the worker s share in the total contribution averages 65 per cent competition is afflicted by a small number of administrators and a high level of concentration administrative costs are high and stagnant capital returns are fair but declining portfolio diversification has been achieved only in chile and peru labour force coverage has declined in all ten countries and gender and income inequalities have expanded copyright 2006 oxford university press

a multivariate cointegration analysis of the role of energy in the us macroeconomy abstract this paper extends my previous analysis of the causal relationship of gdp and energy use in the usa in the post war period a majority of the relevant variables are integrated justifying a cointegration analysis the results show that cointegration does occur and that energy input cannot be excluded from the cointegration space the results are plausible in terms of macroeconomic dynamics the results are similar to my previous granger causality results and contradict claims in the literature based on bivariate models that there is no cointegration between energy and output

energy and economic growth grounding our understanding in physical reality this article attempts to summarise the complex wide ranging and unresolved debate within the economics literature on the possibility of decoupling economic growth from energy use it explores the difference between neo classical and ecological economic worldviews and highlights how the ecological economic approach attempts to ground its analysis within the physical limits implied by the laws of thermodynamics once these laws are accounted for the possibility of decoupling economic growth from energy use seems more limited than neo classical economics implies analysis of empirical evidence also demonstrates that observed improvements in gdp energy use ratios in the usa are better explained by shifts towards higher quality fuels than by improvements in the energy efficiency of technologies this implies a need to focus on decarbonising energy supply furthermore where energy efficiency improvements are attempted they must be considered within the context of a possible rebound effect which implies that net economy wide energy savings from energy efficiency improvements may not be as large as the energy saved directly from the efficiency improvement itself both decarbonising energy supply and improving energy efficiency require the rapid development and deployment of new and existing low carbon technologies this review therefore concludes by briefly outlining areas of economic thought that have emerged as a result of engagement between economists and experts from other disciplines they include ecological evolutionary and institutional economics all of which can make policy relevant contributions to achieving a transition to a low carbon economy

energy consumption economic growth and prices a reassessment using panel vecm for developed and developing countries this paper reinvestigates the energy consumption gdp growth nexus in a panel error correction model using data on 20 net energy importers and exporters from 1971 to 2002 among the energy exporters there was bidirectional causality between economic growth and energy consumption in the developed countries in both the short and long run while in the developing countries energy consumption stimulates growth only in the short run the former result is also found for energy importers and the latter result exists only for the developed countries within this category in addition compared to the developing countries the developed countries elasticity response in terms of economic growth from an increase in energy consumption is larger although its income elasticity is lower and less than unitary lastly the implications for energy policy calling for a more holistic approach are discussed c 2006 elsevier ltd all rights reserved

structural break unit root and the causality between energy consumption and gdp in turkey abstract this paper tries to investigate a series of unit root and causality tests to detect causality between the gdp and energy consumption in turkey employing hsiao s version of granger causality method for the 1950 2000 period the conventional unit root tests indicate the series are i 1 whereas the endogenous break unit root tests proposed by zivot and andrews zivot e and andrews d w k 1992 further evidence on the great crash the oil price shock and the unit root hypothesis journal of business and economics statistics 10 251 270 and perron perron p 1997 further evidence on breaking trend functions in macroeconomic variables journal of econometrics 80 355 385 reveal that the series are trend stationary with a structural break therefore it is inappropriate to take the first difference of the data to achieve stationarity the main conclusion of this study is that there is no evidence of causality between energy consumption and gdp in turkey based on the detrended data

the relationship between energy consumption energy prices and economic growth time series evidence from asian developing countries this paper estimates the causal relationships between energy consumption and income for india indonesia the philippines and thailand using cointegration and error correction modelling techniques the results indicate that in the short run unidirectional granger causality runs from energy to income for india and indonesia while bidirectional granger causality runs from energy to income for thailand and the philippines in the case of thailand and the philippines energy income and prices are mutually causal the study results do not support the view that energy and income are neutral with respect to each other with the exception of indonesia and india where neutrality is observed in the short run c 2000 elsevier science b v all rights reserved jel classifications c22 q43 q48

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

energy use and output growth in canada a multivariate cointegration analysis using a neo classical one sector aggregate production technology where capital labor and energy are treated as separate inputs this paper develops a vector error correction vec model to test for the existence and direction of causality between output growth and energy use in canada using the johansen cointegration technique the empirical findings indicate that the long run movements of output labor capital and energy use in canada are related by two cointegrating vectors then using a vec specification the short run dynamics of the variables indicate that granger causality is running in both directions between output growth and energy use hence an important policy implication of the analysis is that energy can be considered as a limiting factor to output growth in canada

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
