estimating residential demand for electricity in greece abstract this paper examines the residential demand for electricity in greece the issues of structural stability price and income sensitivity of both long and short run residential demand for electricity in greece were examined employing monthly data over the period 1986 1999 the long run residential demand for electricity is estimated taking into account changes in weather conditions weighted by the size of the population employing multivariate framework analysis a long run residential demand function for electricity sensitive to real income price level and weather conditions is found to exist and the importance of short run deviations is presented using vector error correction model vecm estimation the empirical evidence suggests the presence of a stable residential demand for electricity in greece both in the long and short run periods and the policy implications of such a relationship are presented

the effect of urbanization affluence and trade openness on energy consumption a time series analysis in malaysia abstract this paper investigates the impact of urbanization on energy consumption by applying the stochastic impacts by regression on population affluence and technology stirpat in case of malaysia the study covers the time period of 1970q1 2011q4 the unit root test and the ardl bounds testing approach have been applied to examine integrating properties and long run relationship in the presence of structural breaks our results validated the existence of cointegration and exposed that urbanization is a major contributor in energy consumption affluence raises energy demand capital stock boosts energy consumption trade openness leads to affluence and hence increases energy consumption the causality analysis finds that urbanization granger causes energy consumption the feedback effect is found between energy consumption and affluence and energy consumption and capital the bidirectional causality exists between trade openness and energy consumption

aggregate demand for electricity in south africa an analysis using the bounds testing approach to cointegration abstract electricity demand in south africa has grown at a very rapid rate over the past decade as part of reform initiatives to enhance long term sustainability of the country s electricity industry south africa s authorities have in recent years sought to develop an electricity pricing framework that is cost reflective and forms the cornerstone of demand management schemes meant to foster changes in consumption behaviour and enhance efficiency in resource use the effects of any pricing policy on aggregate electricity consumption will depend on a useful understanding of the factors that influence electricity demand and the magnitude to which electricity demand responds to changes in such factors in this context this paper applies the bounds testing approach to cointegration within an autoregressive distributed lag framework to examine the aggregate demand for electricity in south africa during the period 1960 2007 the results indicate that in the long run income is the main determinant of electricity demand with electricity prices having an insignificant effect on aggregate electricity demand future pricing policies will need to ensure that electricity prices are cost reflective and enhance efficiency of electricity supply and use

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

battese coelli estimator with endogenous regressors abstract we provide a framework for dealing with the endogeneity problem in the battese coelli estimator for productive efficiency measurement

how should control theory be used to calculate a time consistent government policy we study different solutions to a simple one dimensional linear quadratic game with a large number of private agents and a government a time consistent solution is defined as a solution to the hamilton jacobi bellman equation i e as a policy for which the government has noprecommitment capability this solution is compared to a policy where the government has an instantaneous pre commitment i e an equilibrium in which the government has a period by period leadership in both cases we show how control theory should be applied to calculate the equilibrium and how to relate these equilibria to the differential game literature

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

the sources of sovereign risk a calibration based on levy stochastic processes abstract governments choose to issue risky or riskless debt depending on the nature of the stochastic process of output we use brownian motion and poisson shocks a modeling method in the literature on corporate default known as levy processes to approximate a decomposition of the output process into a smooth and a jump component using an eaton and gersovitz 1981 model of debt repudiation we show that the brownian part explains the counter cyclical behavior of the current account and the poisson part explains the risk of default thus enabling our model to account for key stylized facts regarding sovereign risk

debt relief and adjustment effort in a multi period model abstract this paper shows that if the period following the granting of debt relief is taken into account debt relief increases adjustment effort investment irrespective of whether there is an initial debt overhang or not

the demand for residential electricity in south africa abstract this paper examines the residential demand for electricity in south africa as a function of real gross domestic product per capita and the price of electricity during the period 1978 2005 we make use of the bounds testing approach to cointegration within an autoregressive distributed framework suggested by pesaran et al 2001 bounds testing approaches to the analysis of level relationships journal of applied econometrics 16 3 289 326 following the literature we use a linear double logarithmic form using income and price as independent variables in the empirical analysis in the long run we find that income is the main determinant of electricity demand while electricity price is insignificant

energy demand in ghana a disaggregated analysis this paper presents a comprehensive analysis of energy demand in ghana by estimating demand functions for key disaggregated energy components including gasoline diesel liquefied petroleum gas lpg kerosene biomass residual fuel oil rfo and electricity our results show that energy prices income urbanization and economic structure are significant demand drivers of the different energy types in ghana with varying estimated elasticities further there is evidence of high degree of inter fuel substitution in energy demand in ghana particularly from gasoline diesel and kerosene towards lpg consumption we recommend among different policy options a customization of energy price subsidization policies especially on lpg to reduce the unintended beneficiary dilemma or spillover effect of current government policy other policies such as intensification of energy conservation programs and market entry of independent power trading companies to enhance energy service delivery through competition are also discussed

on the empirics of foreign aid and growth the present paper re examines the effectiveness of foreign aid theoretically and empirically using a standard olg model we show that aid inflows will in general affect long run productivity the size and direction of the impact may depend on policies deep structural characteristics and the size of the inflow the empirical analysis investigates these possibilities overall we find that aid has been effective in spurring growth but the magnitude of the effect depends on climate related circumstances finally we argue that the collier dollar allocation rule should be seriously reconsidered by donor agencies if aid effectiveness is related to climate the usefulness of foreign aid in promoting growth in developing countries has been an area of controversy ever since rosenstein rodan in 1943 advocated for aid to eastern and south eastern europe browsing through successive editions of a leading textbook in development economics provides a telling illustration of how the confidence in aid effectiveness dwindled over the years in the first edition of leading issues in economic development meier 1964 dedicated a full 18 page section to the issue of foreign aid he started out asking how much aid by the time of the sixth edition meier 1995 the treatment of foreign aid had been cut into half and the questions in focus were why official assistance and does aid work in the 2000 edition meier and rauch 2000 foreign aid is not even listed in the index

did high debts distort loan and grant allocation to ida countries summary we examine the allocation of net loans net transfers and grants to ida countries over the period 1982 2008 focusing on the role of debt and debt sustainability in the decisions of multilateral and bilateral donors we find no evidence of defensive lending but strong evidence of defensive granting a significant negative reaction of net loans to the debt ratio indeed characterizes the decisions of both multilateral and bilateral creditors the impact of lower loans on the budget of debtor countries is however accommodated through higher grants in addition to debt relief these findings are consistent with a substitution of grants for loans and with the new approach to debt sustainability but question the efficiency and selectivity of foreign aid

the economics of development a survey i the subject our definition of the subject will be the use of economic analysis to understand the economies of poor or developing countries this includes in particular how standards of living in the population are determined and how they change over time and further how policy can or should be used in the influence of these processes the definition contains in principle much or most of analytical methods in economics insofar as they can be put to use in the examination of the issues of interest this is as it should be but it poses a problem for a survey in a journal a comprehensive treatment is infeasible so we shall follow a different route the survey will focus on what i take to be the major themes and approaches which characterise the productive aspects of the subject there is therefore no pretence at being exhaustive the purpose is rather to highlight some of the advances many of these have been of real substance there are a number of possible purposes for a survey and it is important to be clear at the outset for whom it is intended what it is and what it is not this survey is addressed to economists and students of economics who know the tools of their trade but not necessarily how they have been applied to and fashioned for the analysis of the economics of developing countries it is a description of the ways in which problems can be productively formulated and approached in terms of examples chosen for their intrinsic importance and interest the vastness of the subject means that we have to be highly selective it does not seek to provide a summary evaluation of the current view of the appropriate response to immediate policy questions it is not a history of thought nor a research manifesto nor an attempt to adjudicate or settle the major debates where they arise naturally from the major purpose some judgements on these subjects will be offered but they do not themselves constitute the primary intent of this survey there are three lines of enquiry or sets of questions which have i suggest been distinctive of the most fruitful work in development economics they will

the debt overhang and the disincentive to invest abstract this paper is an attempt to explore the debt overhang hypothesis by an empirical examination of the investment experience of 13 severely indebted countries it begins with a discussion of the disincentive effect of debt overhang which is linked to some aspects of the adjustment measures that these countries are undergoing viz devaluation and reduction in public sector deficits this is followed by empirical analysis which demonstrates that first in countries with a debt overhang external debt captures many of the effects of other explanatory variables that traditionally explain investment second through 1971 1991 the relationship between external debt and investment is consistently a negative one however the first half of the period has strong time influences that exercise a positive influence on investment in the second half of the period time effects turn negative too thus explaining the fall in investment levels observed after 1982

policy selectivity forgone debt and donor behavior in africa authors assess the dynamics behind the high net resource transfers by donors and creditors to sub saharan african countries analyzing the determinants of overall net transfers for a panel of 37 recipient countries in 1978 98 authors find that country policies mattered little donors especially bilateral donors actually made greater transfers to countries with high debt largely owed to multilateral creditors when policies were bad authors conclude that comprehensive debt relief has the potential though not the certainty to restore selectivity in support of good policies that would make development assistance more effective going forward and increase public support in donor countries

sovereign debt relief and its aftermath this paper studies sovereign debt relief in a long term perspective we quantify the relief achieved through default and restructuring in two distinct samples 1920 1939 focusing on the defaults on official government to government debt in advanced economies after world war i and 1978 2010 focusing on emerging market debt crises with private external creditors debt relief was substantial in both eras averaging 21 of gdp in the 1930s and 16 of gdp in recent decades we then analyze the aftermath of debt relief and conduct a difference in differences analysis around the synchronous war debt defaults of 1934 and the baker and brady initiatives of the 1980s 1990s the economic landscape of debtor countries improves signicantly after debt relief operations but only if these involve debt write offs softer forms of debt relief such as maturity extensions and interest rate reductions are not generally followed by higher economic growth or improved credit ratings jel e6 f3 n0 and h6

the dynamics of electricity demand in pakistan a panel cointegration analysis abstract this paper examines the dynamics of electricity demand in pakistan at the aggregate and sectoral levels over the period 1978 2012 panel cointegration test and fully modified ordinary least squares method is employed to determine the long run relationship between electricity consumption real income real price of electricity and domestic price of non energy products the results reveal that electricity demand is more responsive to changes in income than changes in prices at the aggregate and disaggregate levels short run and long run income elasticities are positive and statistically significant supporting the conservation hypothesis it appears from the results that long run price elasticities are negative and significant at the aggregate level and for the agriculture commercial residential sectors and public utilities the short run price elasticities are significant but low in magnitude which implies that changes in electricity price exert minimal effect on the electricity consumption in pakistan the domestic price of non energy products is positive and significant for aggregate sample in the short run the domestic price of non energy products exert significant negative positive impact on electricity demand in the agriculture industrial sectors the results thus provide important information to the agents operating in the electricity market regarding the income and pricing policies and helps in planning the future strategy of electricity demand management

uncertainty economic reforms and private investment in the middle east and north africa during the 1980s and the 1990s private investment in the middle east and north africa mena has on average shown a decreasing or stagnant trend this contrasts with the situation of the asian economies where private investment has always been more dynamic in this paper it is empirically shown for a panel of 39 developing economies among which four mena countries that in addition to the traditional determinants of investment such as the growth anticipations and the real interest rate government policies explain mena s low investment rate insufficient structural reforms which have most of the time led to poor financial development and deficient trade openness have been a crucial factor for the deficit in private capital formation the economic uncertainties of the region have represented another factor of the firm s decisions not to invest these uncertainties have consisted of the external debt burden and various measures of volatility

modelling aggregate domestic electricity demand in ghana an autoregressive distributed lag bounds cointegration approach in spite of the varying supply boosting efforts made by various governments to deal with the existing demand supply gap in the electricity sector the incessant growth in aggregate domestic electricity demand has made these efforts futile as an objective this paper attempts to identify the factors responsible for the historical growth trends in aggregate domestic electricity demand quantifying their effects both in the short run and long run periods using the ardl bounds cointegration approach and the sample period 1975 to 2005 in the long run real per capita gdp industry efficiency structural changes in the economy and degree of urbanisation are identified as the main driving force behind the historical growth trend in aggregate domestic electricity demand however in the short run real per capita gdp industry efficiency and degree of urbanisation are the main drivers of aggregate domestic electricity demand industry efficiency is the only factor that drives aggregate domestic electricity demand downwards however the negative efficiency effect is insufficient to have outweighed the positive income output and demographic effects hence the continual growth in aggregate domestic electricity demand as a policy option we recommend that appropriate electricity efficiency standards be implemented at the industry level

the demand for residential industrial and total electricity 1973 1998 this paper estimates residential industrial and total electricity demand by a partial adjustment approach and by a simultaneous equation approach simultaneous equation models are more appropriate since they provide negative price elasticity estimates for the residential industrial and total electricity samples flow adjustment models yield positive price elasticity estimates in some cases suggesting they fail to identify proper supply considerations that may be influencing prices the simultaneous equation approach suggests that residential customers are more price sensitive than industrial customers weather seems to have the greatest impact on the residential sector and cold weather appears to affect demand more than hot weather

evidence for the ineffectiveness of debt rescheduling as a policy instrument where an economy cannot meet its external debt service obligations it is forced to appeal to creditors for rescheduling of the debt as such rescheduling is evidence of a country s incapacity to carry a debt burden this article explores factors that explain the probability of a country requiring debt rescheduling in a panel framework the current literature is extended by modelling a dynamic random effects panel probit in order to identify a presence of state dependence after controlling for country heterogeneity we find clear evidence of state dependence when a 2 year lag of the dependent variable is allowed for suggesting that overall the fact that a country has experienced a rescheduling arrangement in the past does indeed make them more likely to experience further rescheduling the article stresses that in order to draw the appropriate policy conclusions from this finding one must understand that the debt rescheduling variable is itself a policy response variable the fact that further resche

electricity demand analysis using cointegration and arima modelling a case study of turkey in the early 2000s the republic of turkey has initiated an ambitious reform program in her electricity market which requires privatization liberalization as well as a radical restructuring the most controversial reason behind or justification for recent reforms has been the rapid electricity demand growth that is to say the whole reform process has been a part of the endeavors to avoid the so called energy crisis using cointegration analysis and autoregressive integrated moving average arima modelling the present article focuses on this issue by both providing an electricity demand estimation and forecast and comparing the results with official projections the study concludes first that consumers respond to price and income changes is quite limited and therefore there is a need for economic regulation in turkish electricity market and second that the current official electricity demand projections highly overestimate the electricity demand which may endanger the development of both a coherent energy policy in general and a healthy electricity market in particular

large external debt and slow domestic growth a theoretical analysis abstract this paper analyzes the optimal rescheduling strategy of lenders whose claims on a country show a discount on the secondary markets the paper shows that lenders should proceed as follows they should split the debt into two components a performing and a nonperforming part they should act as if the debt amounted to the performing part and scale down how much money the borrower should service on that part only as a result it is shown that the efficient servicing of the debt crowds in investment the paper relates this result to the debt overhang argument according to which too large a nominal claim may reduce investment and the market value of the debt

low investment and large ldc debt in the 1980s this paper aims at disentangling the correlation between ldc debt and investment in the 1980s the author shows that a large debt was not an unconditional predictor of low investment in the 1980s nor was investment abnormally low when compared to a financial autarky rate calculated in the text he does find however that the actual service of the debt crowded out investment for the rescheduling countries he shows that 1 percent of gdp paid abroad reduced domestic investment by 0 3 percent of gdp this is identical to the correlation between investment and foreign finance observed in the 1960s copyright 1993 by american economic association

an empirical analysis of energy demand in namibia abstract using a unique database of end user local energy data and the recently developed autoregressive distributed lag ardl bounds testing approach to cointegration we estimate the long run elasticities of the namibian energy demand function at both aggregated level and by type of energy electricity petrol and diesel for the period 1980 2002 our main results show that energy consumption responds positively to changes in gdp and negatively to changes in energy price and air temperature the differences in price elasticities across fuels uncovered by this study have significant implications for energy taxation by namibian policy makers we do not find any significant cross price elasticities between different fuel types

on the estimation of zero inefficiency stochastic frontier models with endogenous regressors in this paper we investigate endogeneity issues in the zero inefficiency stochastic frontier zisf models by mean of simultaneous equation setting specifically we allow for one or more regressors to be correlated with the statistical noise a modified limited information maximum likelihood liml approach is used to estimate the parameters of the model moreover the firm specific inefficiency score is also provided limited monte carlo simulations show that the proposed estimators perform well in finite sample

policy watch debt relief at the gleneagles summit in july 2005 the heads of state from the g 8 countries the united states canada france germany italy japan russia and the united kingdom called on the international monetary fund imf the world bank and the african development bank to cancel 100 percent of their debt claims on the world s poorest countries the world s richest countries have agreed in principle to forgive roughly d55 billion dollars owed by the world s poorest nations this article considers the wisdom of the proposal for debt forgiveness from the standpoint of stimulating economic growth in highly indebted countries in the 1980s debt relief under the brady plan helped to restore investment and growth in a number of middle income developing countries however the debt relief plan for the heavily indebted poor countries hipc launched by the world bank and the international monetary fund in 1996 has had little impact on either investment or growth in the recipient countries we will explore the key differences between the countries targeted by these two debt relief schemes and argue that the gleneagles proposal for debt relief is at best likely to have little effect at all debt relief is unlikely to help the world s poorest countries because unlike the middle income brady countries their main economic difficulty is not debt overhang but an absence of functional economic institutions that provide the foundation for profitable investment and growth we will show that debt relief may be more valuable for brady like middle income countries than for low income ones because of how it leverages the private sector

to give or to forgive aid versus debt relief is generalized debt relief an effective development strategy or should assistance be tailored to countries characteristics to answer this question the authors build a simple model in which recipient governments reveal their creditworthiness if donors offer them to choose between aid and debt relief since offering such a menu is costly it is preferred by donors only when the cost of assistance is low and the probability that an indebted country is creditworthy is high enough for lower probabilities and higher costs of assistance donors prefer a policy of only debt relief very limited aid is the preferred policy only for high costs of assistance and low probabilities that the government is creditworthy

debt relief investment and growth from 1989 to 2004 the donor community provided approximately 400 billion in debt relief to developing countries in an attempt to promote growth and reduce poverty using a sample of 118 developing countries this paper empirically assesses the impact of debt relief on growth via 1 resources made available for investment from reduced debt service payments and 2 improved incentives to invest from a reduced debt stock although the results show no general evidence of a growth effect from debt relief the study provides certain evidence that it promotes investment and thereby growth in countries not classified as hipcs

rewarding the profligate and punishing the prudent and poor some recent proposals for debt relief at a conference organized in june 1986 by the overseas development council on the future of the world bank former west german chancellor helmut schmidt investment banker felix rohatyn and the chairman of the federal reserve board paul volcker all suggested that the massive 60 billion trade surplus of japan be mobilized to solve what they termed as the debt problem of the third world mr barber conable the new president of the world bank is quoted by the new york times 3 july 1986 as saying clearly there is the expectation that japan in view of the light defense burden it carries will participate fully in solving collective debt problems of the world he characterized the japanese surpluses as a considerable world asset and suggested that establishing a special facility such as the one established by the imf in the 1970s to tap saudi arabia s surplus petro dollars to recycle them would be one way of dealing with it nearly a year ago in october 1985 at the annual meetings of the world bank and imf at seoul us treasury secretary james baker signaled a shift in the us approach to the debt crisis the baker plan aimed to help highly indebted middle income countries 15 were mentioned by baker 10 of them in latin america resume growth and achieve adjustment towards a sustainable debt position through the adoption of the following course of action by lenders debtors and multilateral agencies within the context of the then prevailing imf supervised case bycase approach commercial banks the world bank and other multilateral development banks were to increase lending to these countries baker suggested that the commercial banks commit a total of 20 billion in net new lending over 198688 and the multilateral development banks an additional 9 billion during the same period this increased net lending was to be in support of the adoption of market oriented policies by indebted nations growth was to be promoted inflation reduced and external balance restored by expanding the role of the private sector and of markets both domestically and internationally the first offspring of the baker plan is the recent growth oriented adjustment plan for mexico which was foisted upon a reluctant imf perhaps the world s last unreconstructed bastion of adjustment through austerity by the combined pressure of the us treasury and federal reserve board and the mexican threat of repudiation the imf s reservations concerned the budgetary features of the package not the novel real growth and oil price contingency clauses which it supported the 18 month standby arrangement with the imf provides mexico with sdr 1 4 billion about 1 7 billion in support of what is described as a comprehensive program of adjustment and structural reform the total financing package amounts to 12 billion of which 6 billion is to come from the commercial banks mexico s economic problems had of course been intensified dramatically as a result of the drop in the price of oil policies aimed at bringing mexico s real gdp growth to 3 5 by 1987 from recent negative growth rates of 4 or 5 involve a variety of growth oriented market friendly adjustment measures increased public investment current expenditure cuts tax reform measures marketbased adjustments in tariffs and prices charged by public sector enterprises liberalizing trade measures mexico is about to join the ga7t and only very mild by traditional imf standards budgetary restraint a reduction in the deficit gdp ratio by three percentage points over 1986 87 the aspect of the mexican program of most interest for this discussion is the actions taken

debt relief for low income countries is it effective and efficient in recent years religious bodies campaigning groups and parts of the media have made a strong moral case for debt relief accusing creditors of imposing an excessive burden of debt on low income countries and thereby forcing them to cut back in other areas of government expenditure such as education and health with deleterious effects on poverty reduction and economic growth the case for debt relief is also made from the other side of the political spectrum most notably in the recent report of the international financial institution advisory commission sponsored by the us congress the meltzer report which amongst other measures called for complete debt cancellation by the imf and other ifis

electricity demand in kazakhstan properties of electricity demand in transition economies have not been sufficiently well researched mostly due to data limitations however information on the properties of electricity demand is necessary for policy makers to evaluate effects of price changes on different consumers and obtain demand forecasts for capacity planning this study estimates kazakhstan s aggregate demand for electricity as well as electricity demand in the industrial service and residential sectors using regional data firstly our results show that price elasticity of demand in all sectors is low this fact suggests that there is considerable room for price increases necessary to finance generation and distribution system upgrading secondly we find that income elasticity of demand in the aggregate and all sectoral models is less than unity of the three sectors electricity demand in the residential sector has the lowest income elasticity this result indicates that policy initiatives to secure affordability of electricity consumption to lower income residential consumers may be required finally our forecast shows that electricity demand may grow at either 3 or 5 per year depending on rates of economic growth and government policy regarding price increases and promotion of efficiency we find that planned supply increases would be sufficient to cover growing demand only if real electricity prices start to increase toward long run cost recovery levels and policy measures are implemented to maintain the current high growth of electricity efficiency

electricity output ratio and sectoral electricity use the case of east and southeast asian developing countries abstract continuing a recent line of investigation the relationship between electricity use and economic growth and the changes in the sectoral composition of electricity consumption are examined for eight developing countries in east and southeast asia it is found that the relative rate of growth of electricity consumption to gdp declined over time and there were no systematic variations in the sectoral composition of electricity use both over time and across countries

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

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

electricity consumption and economic growth a case study of china abstract this study examines the relationship between electricity consumption and economic growth in china during 1950 1980 the results show that the income elasticity of electricity consumption is significantly greater than one ranging from 2 33 to 2 72 and the electricity gdp ratio or electricity intensity has increased over time with the growth rate of 7 3 pa during 1950 1980 these results suggest that the policy makers in china should pay more attention to electricity conservation policies and structural changes in production

endogeneity in stochastic frontier models copula approach without external instruments this papers considers an alternative estimation procedures for estimating stochastic frontier models with endogenous regressors when no external instruments are available the approach we propose is based on copula function to directly model the correlation between the endogenous regressors and the composed errors estimation of model parameters is done using maximum likelihood monte carlo simulations are used to assess and compare the finite sample performances of the proposed estimation procedures

gmm estimation of stochastic frontier model with endogenous regressors a convenient and simple gmm procedure for estimating stochastic frontier models in the presence of endogenous regressors is proposed monte carlo simulations show that the proposed estimator works very well in finite samples we apply the proposed method to panel data of norwegian dairy farms to illustrate the usefulness of the proposed approach

donors mechanisms for financing international and national public goods loans or grants this paper investigates whether three classes of donors multilateral organisations regional institutions and bilateral donors tailor their mix of grants and loans to reflect international benefit spillovers and recipient specific benefits derived from aid funded activities in developing and transition countries to account for recipient benefit shares donors should use a greater share of grants when supported activities yield a larger portion of international public benefits a greater reliance on loans is appropriate when a large portion of recipient specific benefits are associated with the assistance by reflecting recipient benefit shares in the grant loan mix donors assistance also promotes allocative efficiency using the credit reporting system crs database from oecd for 1980 2000 our analysis establishes that various donor classes apply different grant loan mixtures when supporting the environment health knowledge and governance sectors of recipient countries we employ analysis of variance and other statistical comparisons of the means to investigate differences among donor classes we demonstrate that bilateral donors do the best job in tailoring their grant loan mix to accord with the extent of international public good benefits embodied in the aid supported activity multilateral organisations grant loan mix is intermediate of the three types of donors with some evidence of them relying more on grants to finance activities that possess a larger share of international public good spillovers regional institutions however do not discriminate their grant loan mix by either sectors or the associated public good spillovers this finding suggests that regional development banks need to adjust their grant loan mix to better account for international benefit spillovers if these institutions are to warrant the increased funds to underwrite regional public goods that they have been seeking if however their mix is institutionally set then the stakeholders must give these institutions greater flexibility to tailor their grants and loans to who benefits from the aid supported public goods this is the first paper to empirically ascertain whether the grant loan mix is tied to the inherent publicness of the aid funded activities

official debt restructurings and development abstract despite the frequency of official debt restructurings little systematic evidence has been produced on their characteristics and implications using a dataset covering more than 400 paris club agreements this paper fills that gap it provides a comprehensive description of the evolving characteristics of these operations and studies their impact on debtors the progressive introduction of new terms of treatment gradually turned the paris club from an institution primarily concerned with preserving creditors claims into an instrument to foster development in the world s poorer nations among other objectives our study finds that more generous restructuring conditions involving nominal relief are associated with an acceleration of per capita gdp growth and with a reduction in poverty and inequality we also find that countries receiving nominal relief tend to receive lower aid flows subsequently the opposite being the case for countries receiving high reductions in the net present value of their obligations but no nominal haircuts

prospective aid and indebtedness relief a proposal primary needs of human development are not met in poor development countries although ambitious goals have been set by the international community to meet specific human development targets by 2015 official development aid is lagging and excessive external debt continues to drain much needed resources from poor countries despite the recent hipc highly indebted poor countries initiative this paper outlines a 15 year program for implementing the 2015 human development targets while resolving fully the debt overhang problem for a set of 49 poor countries the proposal requires additional contributions from 23 rich countries amounting to 0 1 of 1 of their gdp over each of the 15y ears although only a small part of the effort would take the form of debt cancellation the outstanding debt of the 49 poor countries would be totally extinct by year 2015 the program to be implemented in a multilateral framework in which all interested parties have an effective voice relies on several basic premises a long term commitment by donors a fair burden sharing among creditors a fair distribution of newly available resources among poor countries heavily indebted or not a targeting of these resources to human development programs a conditionality guaranteeing reasonable aid effectiveness

debt relief and governance quality in developing countries summary in this paper we empirically discuss whether or not debt relief has been economically rational in the past 15 years from analyzing the determinants of debt relief our results suggest that governance quality did not play a role in the decision of creditor countries to forgive debt in the 1990s furthermore even the actual debt burden of highly indebted poor countries was not crucial in deciding whether or not debt forgiveness was granted rather debt relief followed a strong path dependence those countries whose debt had been forgiven in the first half of the 1990s were also granted debt forgiveness in the second half of the decade however this allocation pattern changed at the beginning of the 21st century when path dependence diminished and some dimensions of governance quality were taken into account by donor countries

modelling electricity demand in ghana revisited the role of policy regime changes as policy regime changes demand elasticities are unlikely to be constant since individuals change how they form their expectations and this will change the estimated decision rules in this paper the time varying nature of electricity demand elasticities prior to and post the economic reform period in ghana is analysed using the fm ols three different sample periods pre reform post reform and full period was used in the analysis the result from the full sample period revealed that in the long run electricity demand is significantly affected by industry efficiency industry value added and real per capita gdp urbanization rate however has no significant effect the pre reform estimate showed lower income output and urbanization elasticities but higher industry energy efficiency elasticity relative to the post reform period this suggests that technological change in the pre reform period has been energy saving whilst technological change in the post reform period has been energy consuming the result further showed evidence of changing structure of the economy from the more energy intensive sector to the less energy intensive sector after the reform government should renew her effort in promoting energy saving technologies in the industrial sector and adjust the industrial structure to encourage the expansion of low energy intensive industries or high technology efficient industries

the relationship between turkey s foreign debt and economic growth an asymmetric causality analysis tackling foreign debt that arises as a result of limited and ineffective use of resources is an item that remains on the agenda particularly for developing countries in this study we examine the

debt relief for poor countries conditionality and effectiveness this paper studies the effectiveness of debt relief to stimulate economic growth in the most heavily indebted poor countries we develop a neoclassical framework with a conflict of interest between the altruistic donor and the recipient government and model conditionality as an imperfectly enforceable dynamic contract in contrast to the recent practice of fully cancelling debt optimal incentive compatible conditionality is accompanied by a concessionality level that implies a combination of subsidized loans and outright grants the optimal concessionality level depends on the recipient s access to international financial markets and on the strength of the conflict of interest incentive compatible transfers with optimal concessionality levels generate substantial welfare gains if the donor does not implement the optimal concessionality level and provides subsidized loans only then the effectiveness of transfers decreases in the long run with severe welfare implications in contrast transfers are less effective in the short run if the donor offers outright grants only

ida grants and hipc debt cancellation their effectiveness and impact on ida resources abstract ida is in trouble the world bank s long term plans presume that ida will need all the loan repayments currently scheduled just to keep its program from shrinking in future decades yet the ida grant and hipc debt reduction programs are cutting the flow of repayments foreshadowing major future cuts in ida aid unless the donor countries agree on a plan to offset those costs poor countries will suffer meanwhile the efficiency and effectiveness of the grant and debt cancellation programs have been seriously questioned these programs are evaluated and changes in the bank s future plans for ida are proposed

aid policies and growth the authors of this paper use a new database on foreign aid to examine the relationships among foreign aid economic policies and growth of per capita gdp in panel growth regressions for 56 developing countries and 6 four year periods 1970 93 they find that the policies that have a great effect on growth are those related to fiscal surplus inflation and trade openness they construct an index for those three policies and have that index interact with foreign aid they have instruments for both aid and aid interacting with policies they find that aid has a positive impact on growth in developing countries with good fiscal monetary and trade policies in the presence of poor policies aid has no positive effect on growth this result is robust in a variety of specifications which include or exclude middle income countries include or exclude outliers and treat policies as exogenous or endogenous they examine the determinants of policy and find no evidence that aid has systematically affected policies either for good or for ill they estimate an aid allocation equation and show that any tendency for aid to reward good policies has been overwhelmed by donors pursuit of their own strategic interests in a counterfactual they reallocate aid reduce the role of donor interests and increasing the importance of policy such a reallocation would have a large positive effect on developing countries growth rates

official finance requirements in the 1990s abstract estimates based on a savings gap model with endogenous private bank lending suggest that projections of development aid requirements for sub saharan africa low income asia and latin america by fishlow 1987 the development committes 1988 and the un 1988 are too optimistic a substantial increase in official financial flows to developing countries is necessary it appears that an increase in private bank exposure by 25 a 35 debt reduction and a 35 interest reduction as proposed in the recent brady plan are insufficient to reach minimum growth rates in the three developing regions

when is fiscal adjustment an illusion fiscal adjustment is an illusion when it lowers the budget deficit or public debt but leaves government net worth unchanged conventional measures of the budget deficit largely show the change in public sector debt ideally the measured deficit would reflect the change in public sector net worth many people consider it impractical to try to measure public sector assets my paper does not discuss what the deficit should measure but instead proposes a positive and testable theory of how governments actually behave when an outside agent forces a reduction in a government s conventional deficit and debt accumulation the government responds by lowering asset accumulation or increasing hidden liabilities since government net worth is unchanged such fiscal adjustment is an illusion using data from countries with world bank and imf fiscal adjustment programmes and case studies of emu countries compliance with the maastricht criteria i confirm my theoretical predictions fiscal adjustment in these countries was at least partly an illusion

a cheap lunch for emerging markets removing international financial market imperfections with modern financial instruments summary this paper develops a market based procedure to significantly reduce the indebtedness of emerging markets by applying an asset backed security approach to a pool of emerging market bonds in an extensive simulation study based on historical data the cumulated interest savings over a horizon of 10 years amount to about 20 of the credit sum on average with a standard deviation of 8 and up to 44 for individual countries dependent on the internal distribution of the surplus the theoretical structure of the transaction is explicitly derived in cooperation with professionals from major commercial banks and it implies only negligible implementation cost the implementation requires neither institutional reforms nor debt forgiveness but can supplement or substitute previous measures

optimal deficit and debt in the presence of foreign aid summary external revenue in the form of foreign aid constitutes an important component of the government s budget constraint in many developing countries we derive optimal public spending and the resulting optimal deficit and debt in an optimal control framework when the government seeks to maximize the utility of constituents in the presence of external revenue that cannot be influenced by the government directly but is contingent on public revenue and debt we find that in this context a policy of running budget deficits and accumulating debt becomes optimal in simulations we characterize the size and the path dependency of the optimal deficit and debt

norwegian residential electricity demand a microeconomic assessment of the growth from 1976 to 1993 abstract the norwegian residential electricity consumption increased by an average of 3 annually during the period 1976 1993 political signals indicate that the growth in norwegian residential energy consumption should be reduced and that it may be necessary to increase energy taxes based on data for the sample of households from the annual consumer expenditure survey we study factors that are of importance explaining the growth in norwegian residential electricity demand during this period nearly half of the growth is due to an increase in the number of households while the rest reflects an increase in average consumption per household the increase in average consumption per household is due to an increasing number of households possessing electric household appliances such as dryers and dishwashers an increase in real disposable household income and in the floor space of dwellings

flight capital as a portfolio choice the authors examine flight capital in the context of portfolio choice they estimate the stock of flight capital held abroad and compare it with the stock of real nonfinancial capital held within each country for 51 countries they construct estimates as of 1990 of private domestic capital and flight capital which combined add up to domestic wealth there are large regional differences in the proportion of private wealth that is held abroad ranging from 3 percent in south asia to 39 percent in africa they explain differences in portfolio choice in terms of the capital to labor ratio indebtedness exchange rate distortions and risk ratings all proxies for differences in the risk adjusted rate of return on capital they then apply the results to four policy questions in which private portfolio choices are potentially important the effect of the east asian crisis on domestic capital outflows spillovers the effect of hipc debt relief on capital repatriation and why africa has so much of its private wealth outside the continent their conclusions 1 the four most severely affected east asian countries will eventually lose about 250 billion in domestic wealth as a result of the deterioration in risk between march 1997 and september 1998 2 they found some support for a spillover model 3 the effect of the hipc debt relief initiative on capital repatriation will vary massively between hipc eligible countries 4 africa has by far the lowest capital per worker which makes massive capital flight from africa all the more distinctive three variables explain capital flight in africa exchange rate overvaluation adverse investor risk ratings and high indebtedness

financing vs forgiving a debt overhang abstract this paper examines the tradeoffs facing creditors of a country whose debt is large enough that the country cannot attract voluntary new lending if the country is unable to meet its debt service requirements out of current income the creditors have two choices they can finance the country lending at an expected loss in the hope that the country will eventually be able to repay its debt after all or they can forgive reducing the debt level to one that the country can repay the post 1983 debt strategy of the imf and the us has relied on financing but many current calls for debt reform call for forgiveness instead the paper shows that the choice between financing and forgiveness represents a tradeoff financing gives the creditors an option value if the country turns out to do relatively well creditors will not have written down their claims unnecessarily however the burden of debt distorts the country s incentives since the benefits of good performance go largely to creditors rather than itself the paper also shows that the tradeoff itself can be improved if both financing and forgiveness are made contingent on states of nature that the country cannot affect such as oil prices world interest rates etc

stabilising economic growth through risk sharing macro instruments the risk sharing principles of islamic finance have ironically been studied and used extensively outside the muslim world the development of early european city states was founded on the risk sharing principle the risk sharing financing helped these city states to develop their infrastructure and rule the scientific and economic landscape of the west the western financial system of today still carries traces of risk sharing in the form of venture capital financing albeit the primary focus has diverted to risk shifting based debt financing over the past decades much effort and research has gone into establishing a viable set of islamic financial institutions most muslim nations are heavily indebted with high reliance on multilateral financing primarily based on high interest rates this vicious cycle of interest rates and debt has stunted the growth of these nations and worsened the conditions of the masses this research brings to the forefront the concept of an equity in nature gdp linked paper which allows for enhanced risk sharing based sovereign financing it aims to present empirical proof of the stability this instrument offers in economic growth for a large sample of developing economies comprising bulk of islamic countries while analysing the empirical work a strong favourable argument for this instrument is derived for its benefits in stability through this study we endeavour to initiate a thought provoking and practical discussion for further development of these instruments for the betterment of developing countries

the long run price sensitivity dynamics of industrial and residential electricity demand the impact of deregulating electricity prices abstract this study examines the demand side of ghana s electricity sector we test two important related hypotheses 1 deregulation of electricity price does not promote energy conservation and 2 demand price relationship is not an inverted u shaped the stock and watson dynamic ols is used to address the so called second order bias the result showed that deregulation of electricity price in ghana has induced behaviours that are more consistent with energy conservation improvements the demand price relationship is an inverted u which suggests that there is a price range that end users can tolerate further price rise and still increase their consumption of electricity however the degree of price tolerability is higher for residential consumers than industrial consumers the simulation results showed that further economic growth is likely to compromise energy conservation but more in the industrial sector than the residential sector on the other hand future crude oil price is likely to deteriorate energy conservation in the initial years after 2016 but this trend is likely to reverse after the year 2020 pricing mechanisms are potent to induce energy conservation but inadequate the results suggest that they should be complemented with other stringent policies such as a mandatory energy reduction policy investment in renewables and personalization of energy efficiency programs

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

debt levels debt composition and sovereign spreads in emerging and advanced economies this paper studies the relationship between sovereign spreads and the interaction between debt composition and debt levels in advanced and emerging market countries it finds that in emerging market countries there is a significant correlation between spreads and debt levels this correlation however is not statistically significant in countries where most public debt is denominated in local currency in advanced economies the magnitude of the correlation between debt levels and spreads is about one fifth of the corresponding correlation for emerging market economies in eurozone countries however the correlation between spreads and debt ratios is similar to that of emerging market countries the paper also shows that the financial crisis amplified the relationship between spreads and debt levels within the eurozone but had no effect on the relationship between spreads and debt in stand alone countries finally the paper shows that the relationship between debt levels and spreads is amplified by the presence of large net foreign liabilities this amplifying effect of net foreign liabilities is larger in the eurozone than in stand alone advanced economies the paper concludes that debt composition matters and corroborates the original sin hypothesis that rather than being a mere reflection of institutional weakness the presence of foreign currency debt increases financial fragility and leads to suboptimal macroeconomic policies copyright 2013 oxford university press

curse or blessing has the impact of debt relief lived up to expectations a review of the effects of the multilateral debt relief initiatives for low income countries as the multilateral debt relief initiatives draw to a close this article reviews the impacts of debt relief to low income countries lics building on both the theoretical and empirical literature

residential electricity demand in taiwan this paper examines the residential demand for electricity in taiwan as a function of household disposable income population growth the price of electricity and the degree of urbanization short and long term effects are separated through the use of an error correction model in the long run the income elasticity is unit elastic the own price effect is negative and inelastic in an error correction framework the short run income and price effects are small and less than the long run effects cooling degree day effects have a positive impact on short run consumption we have used a proxy variable urbanization to capture economic development characteristics and changes in electricity using capital stocks not explained by income the variable provides significant explanatory power to the model both in the short and long run we interpret it as controlling for economic development factors not captured by the pure income effect and we think it holds promise for explaining residential electricity consumption in other developing countries

oil nontax revenue and the redistributional foundations of regime stability nontax revenues make up a substantial amount of government revenue around the world though scholars usually focus on individual sources of such revenue for example foreign aid and state owned oil companies using a theory of regime change that builds on recent models of the redistributional foundations of dictatorships and democracies i generate hypotheses regarding all nontax revenue and regime stability i argue that an increase in nontax revenue should be associated with less taxation of elites in democracies more social spending in dictatorships and more stability for both regime types i find support for all three of these hypotheses in a cross sectional time series analysis covering all countries and years for which the necessary data are available significantly i show that the particular source of nontax revenue does not make a difference they all act similarly with regard to regime stability and the causal mechanisms

the anarchy of numbers aid development and cross country empirics the recent literature contains many stories of how foreign aid affects economic growth aid raises growth in countries with good policies or with difficult economic environments or outside the tropics or on average but with diminishing returns the diversity of the results suggests that many are fragile seven important aid growth papers are tested for robustness using 14 minimally arbitrary tests deriving mainly from differences among the studies themselves this approach investigates the importance of potentially arbitrary specification choices while minimizing the arbitrariness in testing choices all of the results appear fragile especially to sample expansion

domestic taxes and the external debt laffer curve this paper highlights the role of the domestic tax system in determining the economic consequences of an external debt overhang the analysis indicates that fairly strong and probably unrealistic assumptions about the domestic tax system are needed to argue that the investment disincentives associated with the debt overlhang are large enough to place a country on the wrong side of the debt laffer curve a simple taxation scheme is specified and it is shown that a country can be on the wrong side of its debt laffer curve only if it is on the wrong side of its tax laffer curve

determinants of electricity demand for newly electrified low income african households access to clean affordable and appropriate energy is an important enabler of development energy allows households to meet their most basic subsistence needs it is a central feature of all the millennium development goals mdgs and while a lack of access to energy may not be a cause of poverty addressing the energy needs of the impoverished lets them access services which in turn address the causes of poverty while much is known about the factors affecting the decisions made when choosing between fuel types within a household few quantitative studies have been carried out in south africa to determine the extent to which these factors affect energy choice decisions it is assumed that the factors traditionally included in economic demand such as price and income of the household affect choice tastes and preferences as well as external factors such as distance to fuel suppliers are expected to influence preferences this study follows two typical low income rural sites in south africa antioch and garagapola where the electricity basic services support tariff ebsst was piloted in 2002 the ebsst is set at 50 kwh month per household for low domestic consumers this is worth approximately r20 1 7us 3 this subsidy is a lifeline tariff where households receive the set amount of units per month free of charge irrespective of whether more units are purchased these data collected in 2001 and 2002 recently collated with detailed electricity consumption data allow us to determine the drivers of electricity consumption within these households the sample analysed is taken from the initial phase of the study when no fbe had been introduced to the households this enabled the study presented here to make use of the well populated datasets to assess what affects the electricity use decision in these households this paper attempts to assess which factors affected the decision making process for electricity consumption within these households a brief history of the electricity industry and the electrification is provided and the theoretical background for the electricity consumption model is provided it was found that income woodfuel usage iron ownership and credit obtained were significant in determining consumption levels within these households price and cross price elasticities were difficult to assess due to lack of data within the sample the results have many possible implications for policy including the effect that easily obtained credit has for low income households

macroeconomic stability and the distribution of growth rates it is often argued that macroeconomic instability can form a binding constraint on economic growth drawing on a new index of stability threshold estimation is used to divide developing economies into two growth regimes depending on a threshold level of stability for the more stable group of countries the output benefits of investment are greater conditional convergence is faster and measures of institutional quality have more explanatory power suggesting that instability forms a binding constraint for the less stable group macroeconomic stability is also shown to dominate several other candidates for identifying distinct growth regimes

the stock of external sovereign debt can we take the data at face value abstract the stock of sovereign debt is typically measured at face value defined as the undiscounted sum of future principal repayments face values are misleading when debts are issued with different contractual forms or maturities in this paper we construct alternative measures of the stock of external sovereign debt for 100 developing countries from 1979 through 2006 that correct for differences in contractual form and maturity we show that our alternative measures 1 paint a very different quantitative and in some cases also qualitative picture of the stock of developing country external sovereign debt 2 often invert rankings of indebtedness across countries which historically defined eligibility for debt forgiveness 3 indicate that the empirical performance of the benchmark quantitative model of sovereign debt deteriorates by roughly 50 once model consistent measures of debt are used 4 show how the spread of aggregation clauses in debt contracts that award creditors voting power in proportion to the contractual face value may introduce inefficiencies into the process of restructuring sovereign debts and 5 illustrate how countries have manipulated their debt issuance to meet fiscal targets written in terms of face values

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

effects of changing trade structure and technical characteristics of the manufacturing sector on energy intensity in ghana abstract this study examined the effects of changing trade structure and changing technical characteristics of the manufacturing sector alongside the effects of foreign direct investment and urbanization on energy intensity in ghana in order to produce a result that is not biased towards non rejection the zivot andrews unit root test with structural break was used the study applied the phillip hansen park and stock watson cointegration models which are more robust to serial correlation and exogeneity problems preliminary findings showed evidence of cointegration the study concludes that the changing technical characteristics of the manufacturing sector after the reform and changing production mix in favor of less energy intensive improved energy efficiency however energy consumption via exports which outweighed the energy saving via imports of capital goods after the reform in 1983 worsened energy efficiency growing urbanization significantly increases energy intensity in all technological diffusion via trade exerts significant influence on energy intensity than technological diffusion via foreign direct investment these results are robust to the cholesky variance decomposition analysis

estimating short and long term residential demand for electricity new evidence from sri lanka this study investigates the short run dynamics and long run equilibrium relationship between residential electricity demand and factors influencing demand per capita income price of electricity price of kerosene oil and price of liquefied petroleum gas using annual data for sri lanka for the period 1960 2007 the study uses unit root cointegration and error correction models the long run demand elasticities of income own price and price of kerosene oil substitute were estimated to be 0 78 0 62 and 0 14 respectively the short run elasticities for the same variables were estimated to be 032 0 16 and 0 10 respectively liquefied petroleum lp gas is a substitute for electricity only in the short run with an elasticity 0 09 the main findings of the paper support the following 1 increasing the price of electricity is not the most effective tool to reduce electricity consumption 2 existing subsidies on electricity consumption can be removed without reducing government revenue 3 the long run income elasticity of demand shows that any future increase in household incomes is likely to significantly increase the demand for electricity and 4 any power generation plans which consider only current per capita consumption and population growth should be revised taking into account the potential future income increases in order to avoid power shortages ill the country

aid and growth what does the cross country evidence really show abstract we examine the effects of aid on growth in cross sectional and panel data after correcting for the possible bias that poorer or stronger growth may draw aid contributions to recipient co

aid and growth regressions this paper examines the relationship between foreign aid and growth in real gdp per capita as it emerges from simple augmentations of popular cross country growth specifications it is shown that aid in all likelihood increases the growth rate and this result is not conditional on good policy there are however decreasing returns to aid and the estimated effectiveness of aid is highly sensitive to the choice of estimator and the set of control variables when investment and human capital are controlled for no positive effect of aid is found yet aid continues to impact on growth via investment we conclude by stressing the need for more theoretical work before this kind of cross country regressions are used for policy purposes

how did highly indebted poor countries become highly indebted reviewing two decades of debt relief how did highly indebted poor countries become highly indebted after two decades of debt relief efforts a set of theoretical models predict that countries with unchanged long run savings preferences will respond to debt relief with a mixture of asset decumulation and new borrowing a model also predicts that a high discount rate government will choose poor policies and impose its inter temporal preferences on the entire economy reviewing the experience of highly indebted poor countries compared with that of other developing countries the author finds direct and indirect evidence of asset decumulation and new borrowing associated with debt relief the ratio of the net present value of debt to exports rose strongly over 1979 97 despite the debt relief efforts average policies in highly indebted poor countries were generally worse than those in other developing countries nor were wars more likely in highly indebted poor countries over time there has been an important shift in financing for highly indebted poor countries away from private and bilateral nonconcessional sources to the international development association and other sources of multilateral concessional financing but this implicit form of debt relief also failed to reduce debt in net present value terms although debt relief is done in the name of the poor the poor are worse off if debt relief creates incentives to delay reforms needed for growth
