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

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

the asymmetric linkage between energy use and economic growth in selected african countries evidence from a nonlinear panel autoregressive distributed lag model abstract this paper endeavors to shed light on the asymmetric heterogeneous relationship between energy use and economic growth in nineteen selected african countries from 1971 to 2014 we employ to this end a nonlinear panel autoregressive distributed lag model and an asymmetric panel causality test the empirical results suggest that the relationship between energy use and economic growth is asymmetric and depends on the phases of economic cycle firstly in periods of economic expansion positive shocks on energy use have a positive and significant effect on economic growth in the long run but have a weak positive effect in the short run negative shocks on energy use have a negative and significant effect on economic growth in the long run but a positive and significant effect in the short run moreover in periods of economic expansion economic growth tends to react more to a decrease in energy use than to an increase in energy use secondly in period of economic contraction positive shocks on energy use accentuate the negative variation of economic growth in the long run while in the short run economic contraction is resorb by negative shocks on energy use thirdly net energy importing economies located in north africa east africa central africa and southern africa are the most subject to energy asymmetric shocks for net energy exporting countries the asymmetric relationship between energy use and economic growth is mixed we also find that negative changes in economic activity lead to negative variations of energy use fourthly positive and negative shocks on the cyclical components of energy use and economic growth do not have over the time the same correlation with positive and negative shocks of one or other of the variables from the research that has been carried out it appears that sound economic policy decisions require information on the asymmetric linkage between energy use and economic growth

eldercare hours work hours and perceived filial obligations in this paper we take a fresh look at the magnitude of the trade off between caring informally for a parent and paid work we adopt a simultaneous approach with a primary focus on how hours of car

what drives energy consumption in developing countries the experience of selected african countries abstract this study investigates the drivers of energy consumption in sub saharan african countries it applies the bounds testing approach to cointegration to time series data at individual country levels over the period from 1970 to 2011 the study finds that energy consumption is cointegrated with real gdp per capita industrial output imports foreign direct investment credit to private sector urbanization and population furthermore the sign and magnitude of long run estimates vary significantly for a single country and across countries depending on the energy consumption variable used overall the findings confirm the leading role of economic growth industrial output population and urbanization economic growth industrial output and population have positive effects on energy consumption in the majority of countries given the urgent need to address climate change african countries should adopt policies to improve energy efficiency and accelerate transition toward renewable energy the african renewable energy initiative launched at the 21st session of the united nations conference of the parties cop21 is an opportunity for african countries to provide and maintain widespread access to reliable and affordable environmentally cleaner energy to meet the requirements of rapid economic growth and improved living standards

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

causality analysis of diesel consumption and economic growth in cameroon abstract this study examines the causal relationship between diesel consumption and economic growth in cameroon by using a three step modern time series technique tests for unit roots cointegration and granger causality based on error correction model are employed on annual data covering the period 1975 2008 empirical results of the study confirm the presence of a long run equilibrium relationship between diesel consumption and economic growth the error correction model shows that an estimated 1 increase in economic growth causes a rise in diesel consumption of 1 30 in the long run the overall results show that there exists bidirectional causality in the long run relationship and no causality in the short run relationship between diesel consumption and economic growth at the 5 level of significance thus the energy policies in cameroon should place priority on the discovery of new oil field and building capacity additions of the refinery to increase production of petroleum products as this would propel the economic growth of the country

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

tests for parameter instability in regressions with i 1 processes this article derives the large sample distributions of lagrange multiplier lm tests for parameter instability against several alternatives of interest in the context of cointegrated regression models the fully modified estimator of phillips and hansen is extended to cover general models with stochastic and deterministic trends the test statistics considered include the supf test of quandt as well as the lm tests of nyblom and of nabeya and tanaka it is found that the asymptotic distributions depend on the nature of the regressor processes that is if the regressors are stochastic or deterministic trends the distributions are noticeably different from the distributions when the data are weakly dependent it is also found that the lack of cointegration is a special case of the alternative hypothesis considered an unstable intercept so the tests proposed here may also be viewed as a test of the null of cointegration against the alternative of no cointegration the tests are applied to three data se

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

the earnings of informal carers wage differentials and opportunity costs a substantial proportion of working age individuals in britain are looking after sick disabled or elderly people often combining their work and caring responsibilities previous research has shown that informal care is linked with substantial opportunity costs for the individual due to forgone wages as a result of non labour market participation in this paper we show that informal carers exhibit further disadvantages even when participating using the british household panel study bhps we decompose wage differentials and show that carers can expect lower returns for a given set of characteristics with this wage penalty varying along the pay distribution and by gender furthermore opportunity costs from forgone wages and wage penalties are estimated and found to be substantial

potential pitfalls for the purchasing power parity puzzle sampling and specification biases in mean reversion tests of the law of one price the ppp puzzle is based on empirical evidence that international price differences for individual goods loop or baskets of goods ppp appear highly persistent or even nonstationary the present consensus is these price differences have a half life that is of the order of five years at best and infinity at worst this seems unreasonable in a world where transportation and transaction costs appear so low as to encourage arbitrage and the convergence of price gaps over much shorter horizons typically days or weeks however current empirics rely on a particular choice of methodology involving i relatively low frequency monthly quarterly or annual data and ii a linear model specification in fact these methodological choices are not innocent and they can be shown to bias analysis towards findings of slow convergence and a random walk intuitively if we suspect that the actual adjustment horizon is of the order of days then monthly and annual data cannot be expected to reveal it if we suspect arbitrage costs are high enough to produce a substantial band of inaction then a linear model will fail to support convergence if the process spends considerable time random walking in that band thus when testing for ppp or loop model specification and data sampling should not proceed without consideration of the actual institutional context and logistical framework of markets

cointegration and threshold adjustment this article proposes an extension to the engle granger testing strategy by permitting asymmetry in the adjustment toward equilibrium in two different ways we demonstrate that our test has good power and size properties over the engle granger test when there are asymmetric departures from equilibrium we consider an application namely whether there exists cointegration among interest rates for instruments with different maturities this issue has been widely tested with mixed results we argue that either cautious policy or possibly opportunistic behavior on the part of the federal reserve implies that an equilibrium relationship between short and long term interest rates exists but that adjustments from disequilibrium are asymmetric in nature empirical tests using u s yields confirm the asymmetric nature of error correction among interest rates of different maturities

structural adjustment in africa insights from the experiences of ghana and senegal abstract structural adjustment in ghana and senegal has helped create an improved framework for economic growth but this is a fragile trend one that could be disrupted by bad weather adverse terms of trade and the vagaries of international assistance the current version of adjustment however has produced little enduring poverty alleviation a weak performance on equity issues together with rising political expectations has generated threats to the sustainability of structural adjustment and overall political stability alternatively adjustment policies can be modified to fully incorporate equity and sustainability objectives in this respect it is critical for the poor to obtain more effective representation in decision making on adjustment through indigenous nongovernment organizations

structural adjustment in ghana abstract ghana s structural adjustment programme has been hailed as an impressive success story with rises in gdp exports net inward financial transfers food production and real minimum wages and decreasing inflation however there are still gaps and problematics both in terms of production economics and human and social failures which require attention if these gains are to be secured and issues such as absolute poverty life expectancy literacy education and health are to be addressed this article looks at gaps and doubts in production and productive efficiency and indicates the way forward for ghanaian policy if this success story is to be continued

rentierism energy and economic growth the case of algeria and egypt 1965 2010 abstract the algerian economy is an example of a high level of rentierism while the egyptian economy shows a low moderate level of rentierism the ardl bounds test approach was used upon annual time series data from 1965 to 2010 the results suggest cointegration for both countries bi causality between energy consumption and growth in the long run was found for algeria there is a reversed negative energy growth nexus adding a new relationship to the traditional four causal hypotheses on the energy growth nexus for egypt we found positive elasticity both of oil price and energy which is in line with the mainstream

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

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

structural change and poverty in africa a decomposition anakysis for cote d ivoire abstract this paper provides evidence that economic destabilization and the absence of managed structural change in an economy can be more harmful to the welfare of the poor than the process of adjustment itself evidence comes from four consecutive years of household survey data from cote d ivoire spanning both a period of adjustment and destabilization these constitute a unique data base in africa to assess the impact of structural change on the poor the analytic methodology used is that of static and dynamic decomposition of poverty measures along policy relevant dimensions

adjustment and economic performance under a fixed exchange rate a comparative analysis of the cfa zone abstract this paper examines the economic performance of the cfa franc zone versus non cfa countries in recent years a modified control group approach is used to compare the evolution of macro economic indicators in the cfa countries vis a vis other sub saharan african countries controlling for initial conditions changing exogenous internal and world environment and policy stance in addition our approach allows for a formal testing of whether zone membership is a random the implication of randomness i e no selection bias is that the cfa zone economies would have performed in the same fashion as the rest of sub saharan africa for example in the absence of the zone our results show that the randomness assumption is only valid for the cases of gdp growth and inflation for other indicators savings investment and export ratios to gdp the decision to participate in the zone is endogenous and is related to the expectation of improved economic performance subsequently in the estimation of the zone s effects on the latter group of indicators we corrected for the ensuing sample selectivity bias by estimating that status indicator participation versus non participation via a probit model our estimation results indicate a weakening competitive position of the cfa members during the second half of 1980s relative to the first half compared with the non cfa countries in terms of output growth as well as the performance of exports investment and savings the exception is domestic inflation with the cfa countries faring better on that front results for a longer term comparison the 1970s versus the 1980s are somewhat mixed while the estimated coefficients for the marginal effect of zone participation corroborates a better performance for the cfa zone over the group of comparators in terms of exports domestic savings and investment and inflation the zone failed to distinguish itself with regard to economic growth in the long run

modeling energy demand some emerging issues abstract the proliferation of papers on energy demand modeling has offered different dimensions both in terms of methodology and estimation while this development has strengthened our understanding of the subject it may render the identification of gaps in the literature arduous for future research thus this study sets out to document some emerging issues that seem to have engendered new directions on energy demand modeling ranging from asymmetric price responses time varying demand parameters triangulation analyses to seasonal and climate change effects it is hoped that access to this review complemented with the previous ones will facilitate the comprehension of the extant literature as well as areas of future research in energy demand modeling

politics and perceived country creditworthiness in international banking this paper marks a departure from most previous studies of country creditworthiness in international banking because it incorporates systematically generated quantitative indicators of political instability in the analysis the authors empirically test for the effects of political instability on perceived country creditworthiness using data on thirty heavily indebted developing countries for the period 1967 86 in addition to economic factors they examine the effects of three types of political instability regime change political legitimacy and armed conflict the authors also distinguish between proximate instability and chronic instability they find significant effects of proximate instability particularly in governmental regime on indicators of countries perceived creditworthiness copyright 1990 by ohio state university press

energy consumption and economic growth evidence from the economic community of west african states ecowas access to modern energy is believed to be a prerequisite for sustainable development poverty alleviation and the achievement of the millennium development goals however theoretical models and empirical results offer conflicting evidence on the relationship between energy consumption and economic growth that we remain largely unsure of the cause and effect nature of this relationship if indeed a relationship exists at all this paper tests in a panel context the long run relationship between energy access and economic growth for fifteen african countries from 1980 to 2008 by using recently developed panel cointegration techniques we adopt a three stage approach consisting of panel unit root panel cointegration and granger causality tests to study the dynamic causal relationships between energy consumption energy prices and growth as well as relationship between electricity consumption prices and growth results show that gdp and energy consumption as well as gdp and electricity move together in the long run by estimating these long run relationships and testing for causality using panel based error correction models we found unidirectional long run and short run causality the causality is running from gdp to energy consumption in the short run and from energy consumption to gdp in the long run there is also evidence of unidirectional causality running from electricity consumption to gdp in the long run this study thus provides empirical evidence of long run and causal relationships between energy consumption and economic growth for our sample of fifteen countries suggesting that lack or limited access to modern energy services could hamper economic growth and compromise the development prospects of these countries

solow meets leontief economic growth and energy consumption abstract this paper proposes a methodology that integrates a growth model with an input output model to analyze the impacts of economic growth on the consumption of energy the integration between the models is carried out by calibrating the growth module which incorporates energetic inputs renewable and nonrenewable in the production function and implementing shocks by the supply side capital labor renewable and nonrenewable energy in the input output model this allows us to verify the pattern of energy consumption for each sector in the input output matrix we apply this methodology to study the energy consumption of eleven economic sectors in brazil using data from the brazilian national accounts and input output matrix ibge and the national energy report ben we conduct experiments involving changes in technological progress growth rate extraction and regeneration rates of both renewable and nonrenewable resources and population growth to analyze the impact of changes in the parameters of the model on the sectoral output growth rate and consequently on the consumption of energy in each economic sector

energy consumption and economic growth evidence from the commonwealth of independent states abstract this study examines the relationship between energy consumption and economic growth for eleven countries of the commonwealth of independent states over the period 1991 2005 within a multivariate panel data framework based on pedroni 1999 pedroni 2004 heterogeneous panel cointegration test and corresponding error correction model cointegration is present between real gdp energy consumption real gross fixed capital formation and labor force with the respective coefficients positive and statistically significant the results of the error correction model reveal the presence of unidirectional causality from energy consumption to economic growth in the short run while bidirectional causality between energy consumption and economic growth in the long run thus the results lend support for the feedback hypothesis associated with the relationship between energy consumption and economic growth

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

biofuels adoption in nigeria attaining a balance in the food fuel feed and fibre objectives abstract the drive towards economic development in nigeria brings about the pursuit of many competing objectives whose attainments depend on limited resources biofuels adoption has been set as an important path among other options for pursuing economic growth and development for the country the federal government of nigeria fgn is currently promoting the production processing and utilization of biofuels in the transport and energy sectors the article examines biofuels adoption in nigeria vis a vis the attainment of a balance in the food fuel feed and fibre objectives crops already profiled as preferred sources of feedstock for the primary biofuels production are also crucial for food feed and fibre the resources needed for producing these crops are limited hence the need for a balance this paper derived data from secondary sources including the food and agriculture organization fao the paper explores some aspects of biofuels sustainability and present recommendations for attaining a balance in the multiple objectives for attaining socioeconomic development

the opportunity costs of informal care does gender matter in this paper we investigate the costs borne by both male and female carers in terms of their forgone formal employment opportunities traditionally informal care was supplied by women but nowadays women are not only more likely to work but also likely to be significant contributors to family finances for women this implies that the size of any forgone earnings cost of informal care is increasing at the same time population ageing is making for increasing numbers requiring care from a policy perspective it is therefore helpful to consider a less traditional but nevertheless important source of informal care men we find that both male and female carers bear indirect costs in that they are less likely to be in paid work than otherwise similar non carers and when they are in paid work they earn significantly less however we find that the motivation for lower employment participation is not the same for men as it is for women

privatization technical efficiency and welfare consequences the case of the cote d ivoire electricity company cie abstract in 1990 cote d ivoire privatized the management of its electric power company lease contracting in this paper we are interested in identifying the economic effect of this institutional change by estimating a stochastic production frontier we have found that productive efficiency improved after privatization thanks to organizational innovations total factor productivity gains have been closely associated with a cost reduction strategy the way these gains have been distributed in a monopoly context suggests that consumers have been the main beneficiaries through a significant decrease of the relative price of electricity

the labour market costs of community care this paper reports an empirical investigation into the influence of informal care responsibilities on the labour supply of women the objective is to examine the argument that the uk policy of caring for the chronic sick in the community involves a nontrivial opportunity cost in the form of the forgone labour supply of the informal carers upon which it relies we find that informal carers who care for less than 20 h per week are in fact more likely to participate in the labour market but tend to work for fewer hours per week than otherwise similar noncarers informal carers who care for 20 h or more a week are less likely to participate but only slightly however when they do undertake formal employment they tend to earn less per hour and work for fewer hours per week

searching for a break in gnp it has been suggested that existing estimates of the long run impact of a surprise move in income may have a substantial upward bias due to the presence of a trend break in postwar u s gross national product data this article shows that the statistical evidence does not warrant abandoning the no trend break null hypothesis a key part of the argument is that conventionally computed p values overstate the likelihood of the trend break alternative hypothesis this is because they do not take into account that in practice the date is chosen based on pretest examination of the data

the validation of granger causality through formulation and use of finance growth energy indexes abstract the paper aims to investigate the finance growth energy nexus validity in pakistan by taking large range of relevant variables and developing indexes focus of the paper is to evaluate the long run relationship between financial development economic development and energy consumption after extracting the indices granger s ordinary least squares ols regression and correlation is used to explain short run deviation in the nexus in order to capture co integration eagle granger approach is applied lastly hurst exponent are used to estimate annual rescaled range statistics to explain deviation during period of analysis granger causality has been empirically tested in a robust way incorporating large range of relevant variables on overall nexus of finance growth energy that has been hardly tested in such depth index formation through econometric analysis is novel part of this study which revealed that in short run financial development index fdi and energy price have significant relationship with energy consumption however in long run analysis has endorsed the concept of granger casualty especially on feedback hypothesis study has practical and theoretical contribution to the literature that could be highly beneficial to policy makers

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

political uncertainty and asset valuation evidence from business relocations in canada abstract quebec s drive for sovereignty from canada has been the source of political uncertainty for decades in canada this paper studies empirically stock market s reaction to the announcements of business relocations from the province of quebec to other provinces within canada similar announcements about toronto are used for control empirical results show that the market s reaction to the announcements of business relocations a from quebec is positive b from toronto is negative and c to toronto is positive the difference in abnormal returns between the quebec and toronto samples is positive and significant

energy use for economic growth a trivariate analysis from tunisian agriculture sector abstract following the importance of energy in the agrarian economies the investigation of the causal relationship between energy consumption in agriculture sector and economic growth has a fundamental role in implementing suitable policies this paper examines the causal relationship between energy consumption and agricultural value added controlling for trade openness in tunisia from 1980 to 2007 the relationship is investigated at aggregated as well as disaggregated components of energy consumption including oil and electricity using granger s technique it is shown that various results are obtained regarding the direction of causality between competing variables nevertheless the most common finding suggest that trade openness and both aggregated and disaggregated energy consumption granger causes agricultural value added therefore the energy led growth and trade led growth hypotheses are supported in the tunisian agriculture sector an important policy implication resulting from this study is that energy can be considered as a limiting factor to agriculture value added and therefore shocks to energy supply would have a negative impact onto agriculture performance furthermore trade liberalization seems to be a stimulus factor to the tunisian agriculture development

carbon emissions energy consumption and output a threshold analysis on the causal dynamics in emerging african economies abstract following the recent global economic downturn attention has gradually shifted towards emerging economies which have experienced robust growth amidst sluggish growth of the world economy a significant number of these emerging economies are in africa rising growth in these economies is associated with surging demand for energy to propel the engines of growth with direct implications on emissions into the atmosphere further these economies are constantly being shaped by series of structural reforms with direct and indirect effects on growth demand for energy etc to this end this paper examines the causal dynamics among energy use real gdp and co2 emissions in the presence of regime shifts in six emerging african economies using the gregory and hansen 1996a j econ 70 99 126 threshold cointegration and the toda and yamamoto 1995 j econometrics 66 225 250 granger causality techniques results confirm the presence of regime shift effects in the long run inter linkages among energy use real gdp and co2 emissions in the countries considered thus indicating that structural changes have both economic and environmental effects hence integration of energy and environmental policies into development plans is imperative towards attaining sustainable growth and development

currency risk and country risk in international banking this paper focuses on the conditions under which banks are subject to currency and country risks on their dollar denominated loans to foreign firms and governments we conclude that currency risk is a function of the rates of domestic and foreign inflation deviations from purchasing power parity and the effect of these deviations on the firm s and the nation s dollar equivalent cash flows country risk is largely determined by the variability of the nation s terms of trade and the government s willingness to allow the national economy to adjust rapidly to changing economic fortunes banks typically try to cope with currency risk when lending to foreign firms and governments either by both denominating and funding their loans in the foreign currency or failing that by denominating their foreign loans in dollars the latter practice appears to protect the banks by shifting any risk associated with exchange rate fluctuations to the borrowers yet to the extent that changes in currency values affected the ability and or willingness of foreign borrowers to repay their dollar loans the exchange risk on these loans is converted into credit risk this is the element of currency risk referred to in the paper s title when the government is the borrower credit risk becomes country risk the objective of this paper is to explore the conditions under which banks are subject to currency and country risks on their dollar denominated foreign loans section i analyzes the sources of currency risk for firms while section ii extends the analysis to study the riskiness of dollar loans to foreign firms under several currency scenarios the political economic circumstances under which dollar loans to foreign governments could be subject to currency and country risk are the subject of section iii section iv discusses in more detail the various political and economic indicators of country risk section v summarizes the paper s key points

energy consumption and economic growth in vietnam abstract this study attempts to analyse the relationship between energy consumption and economic growth in vietnam using the neoclassical solow growth framework for the 1971 2011 period the concept and methods of cointegration and granger causality are used to establish the relationship between the variables of interest our results confirm the existence of cointegration among the variables in particular energy consumption fdi and capital stock were found positively influence economic growth in vietnam the granger causality test revealed unidirectional causality running from energy consumption to economic growth hence vietnam is an energy dependent economy and any energy or environment policy drawn up in an attempt to conserve energy will jeopardise the process of economic development in vietnam for this reason the renewable energy policy should be given attention to provide sufficient supplies of energy to speed up economic expansion investment in r d may be required to incentivise private public institutions to engage in this innovation while the awareness for energy saving policy among public could be integrated to meet social economic development

adjustment and income distribution in an agricultural economy a general equilibrium analysis of cameroon abstract to distinguish policy packages that have favorable characteristics for both structural adjustment and income distribution this paper uses static and dynamically optimizing simulations of a computable general equilibrium cge model based on detailed country and household data from cameroon model results indicate that public spending to reduce transport and marketing costs are beneficial for the poor and for economic growth even at the expense of competing public investments

international retail banking as a strategy an assessment we assess the viability of a bank s strategy of entering into retail banking worldwide wherever regulations permit via a review of literature and evidence on foreign direct investment in banking issues we discuss include the roles of regulation the costs of operating at a distance and in an unfamiliar environment and the advantages or offsetting factors which foreign banks may possess relative to their local competitors the factors the paper examines are uncompetitive host markets product differentiation economies of scale management and technology cost of capital government support and vertical integration

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

what has happened to the urban population in cote d ivoire since the 1980s an analysis of monetary poverty and deprivation over 15 years of household data abstract this article investigates the evolution of urban poverty in its various dimensions in cote d ivoire since the 1980s the robustness of the results is checked using dominance criteria an econometric analysis of poverty complements the analysis the study shows that the dynamic of poverty in terms of existence conditions can significantly differ from that of monetary poverty as was the case in the 1980s monetary poverty increased strongly in the 1990s in spite of a return to sustained growth following the devaluation of the cfa franc poverty in terms of existence conditions rose less before the adjustment and even decreased afterward

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

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

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

electricity use and economic development abstract a study of the relationship between electricity use and economic development in over one hundred countries constituting over 99 of the global economy has been undertaken correlations between electricity consumption capita and gdp capita have been analysed and compared with those between total primary energy supply capita and gdp capita a supporting analysis has correlated the proportion of energy used in the form electricity the e e ratio with gdp capita the general conclusions of this research are that wealthy countries have a stronger correlation between electricity use and wealth creation than do poor countries and that for the global economy as a whole there is a stronger correlation between electricity use and wealth creation than there is between total energy use and wealth the study also shows that in wealthy countries the increase in wealth over time correlates with an increase in the e e ratio the results imply that the energy ratio toe should be replaced by the electricity ratio kwh as a development indicator and more precisely by the e e ratio kwh toe

electricity sector reform in cameroon is privatization the solution abstract the economic difficulties of cameroon and of its government owned companies led the international monetary fund imf and the world bank to set up a vast privatization program with the government s collaboration in the electricity sector the state had a complete control over the industry through the societe national d electricite sonel an integrated monopoly utility under the imf world bank program sonel has been sold to foreign interests this article presents cameroon s electricity sector the proposed reform and the importance of electricity in economic development an evaluation of the reform is presented from two different perspectives first we consider the reform from a theoretical and market design point of view second we challenge the reform from a more fundamental level by questioning the relevance of privatization at this stage of the electricity sector development this brings us to review the strategic place of electricity in economic growth how different countries have dealt with their electricity industry in early development stage and how the objective of multinational corporations could be in conflict with specific electricity sector goals from these two different perspectives we conclude that the imf and the world bank have set up a reform process that is against good public policy we conclude with some suggestions for improving the reform process

balance of payments adjustment in low income developing countries the experiences of kenya and tanzania in the 1970s abstract in the wake of the oil price shock of the mid 1970s the two low income economies of kenya and tanzania adopted growth oriented adjustment strategies the oil shock also coincided with drought which affected tanzania much more adversely by the end of the 1970s the glaring failures in the two countries adjustment performance was in relation to balance of payments and in particular to export growth pricing policies in agriculture were actively applied in the two countries the results of these policies continue to underline the importance of a farmer rewarding price policy but also indicate a strong possibility of crop substitution problems in low income economies special measures were applied to promote manufactured exports subsidies in kenya and primary export processing in tanzania but they were a conspicuous failure policy lessons from these experiences are briefly indicated

what does purchasing power parity mean this paper examines the theoretical and empirical content of purchasing power parity ppp in efficient markets it analyzes the sources of deviations from the strictest version of ppp that exchange adjusted price levels are everywhere identical focusing on the role played by uncertainty relative price changes inappropriate price data transaction costs and government intervention in creating these deviations it then identifies and addresses the key issue involving purchasing power parity are the deviations from ppp that occur sufficiently large persistent and predictable as to enable individuals or governments to successfully exploit them an answer of no is shown to be consistent with both economic theory and the empirical evidence

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