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

scenario based forecast for the electricity demand in qatar and the role of energy efficiency improvements abstract we model the electricity consumption in the market segment that compose the qatari electricity market we link electricity consumption to gdp growth and population growth building on the estimated model we develop long range forecasts of electricity consumption from 2017 to 2030 over different scenarios for the economic drivers in addition we proxy for electricity efficiency improvements by reducing the long run elasticity of electricity consumption to gdp and population we show that electricity efficiency has a crucial role in controlling the future development of electricity consumption energy policies should consider this aspect and support both electricity efficiency improvement programs as well as a price reform

elements for the development of public policies in the residential sector of mexico based in the energy reform and the energy transition law abstract mexico has entered in an important dynamic of structural changes in the energy area proof of this it is the energy reform 2013 and the energy transition law published the last december 24th 2015 thus it is important to carry out studies of the impacts of future politics in the consumption of the population so this study estimate an energy demand system using microdata collected from 97 817 households in a national households income and expenditure survey enigh acronyms in spanish encuesta nacional de ingresos y gastos de los hogares in the 20 years period from 1994 to 2014 the magnitudes of all the fuels are smaller than one indicating that electricity lpg gasoline and public transport are normal goods while lpg is the most inelastic energy source the geographic factor shows that households in the north of mexico tend to consume more gasoline whereas in the south of the country the lowest share of lpg expenditure is reported the rigorous evaluation of energy demanded in households will help policy makers to put forward more efficient reforms

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

determinants of import demand for non renewable energy petroleum products empirical evidence from nigeria abstract this study estimated determinants of import demand for refined petroleum products in nigeria for the period 1984 2013 it employed the autoregressive distributed lag ardl bounds test cointegration method and analysed both long run and short run determinants of import demand for total and specific petroleum products in the long run aggregate and sectoral incomes are significant determinants of import of refined kerosene further real effective exchange rate reer aggregate income gdp manufacturing sector s income domestic energy production dep and population growth rate pgr are drivers of import of refined motor spirit moreover reer dep and manufacturing sector s income are propellers of import of refined distillate fuel also reer and total output of petroleum products are major drivers of total import of refined petroleum products short run results show that previous period gdp pgr and manufacturing and service sectors incomes are determinants of import demand for refined kerosene moreover reer gdp previous pgr and manufacturing sector s income exert significant effects on the import of refined motor spirit further significant effects of reer dep previous pgr domestic output of the product and manufacturing and service sectors incomes on the import demand for distillate fuel were found policy implications of the foregoing are articulated in the paper

price and income elasticities of electricity demand evidence from jamaica abstract jamaica s electricity sector faces supply side challenges demand side policies have the potential to improve electricity use efficiency and reduce the likelihood of electricity disruptions in this paper i use the bounds testing approach to cointegration to obtain long run price elasticity of demand estimates for the period 1970 2014 the analysis focuses on aggregate electricity demand and three categories of consumers residential commercial and industrial the findings suggest that residential and industrial consumers are most responsive to price changes with long run price elasticities of demand of 0 82 and 0 25 respectively price based approaches are likely to be more successful in slowing electricity demand growth in these sectors

econometric modeling of electricity consumption in post war lebanon this paper applies econometric models to investigate determinants of electrical energy consumption in post war lebanon the impact of the gross domestic product gdp proxied by total imports ti and degree days dd on electricity consumption is investigated over different time spans covering the period from 1993 to 1997 the time spans are chosen according to the rationing level of electricity supply for the 1993 1994 time span ti is found to be a significant determinant of energy consumption whereas dd has a negative correlation this inconsistency might be attributed to an extensive rationing policy followed during this period for the 1995 1997 time span which includes reduced rationing period 1995 all electrical energy consumption determinants are found to be significant at the 5 significance level analysis results for the rationing free 1996 1997 time span also show the significance of ti and dd at the 5 level furthermore cointegration analysis for the 1995 1997 and 1996 1997 subsets reveals the existence of a long run relationship between all variables in addition error correction models for both subsets are developed to predict short run dynamics finally statistical performance measures such as mean square error mean average deviation and mean average percentage error are presented for all models

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

electricity planning and implementation in sub saharan africa a systematic review abstract universal electricity access is an important development objective and the focus of a number of key global un initiatives while robust electricity planning is widely believed to be a prerequisite for effective electrification to date no comprehensive overview of electricity planning research has been undertaken on sub saharan africa the world region with the lowest access rates this paper reviews quantitative and qualitative electricity planning and related implementation research considering each of the 49 sub saharan african countries the four regional power pools and the sub continent as a whole applying a broad understanding of electricity planning and a practical limit of 20 reviewed articles per country and region 306 relevant peer reviewed journal articles are included in this review a general classification scheme is introduced that classifies the planning literature along the addressed value chain depth number of different analysed criteria and number of evaluated decision alternatives the literature is found to be strongly clustered in a few countries with less than 5 identified relevant articles in 36 of the 49 countries the total amount of articles per year is clearly increasing over time addressing technology choice operation distribution and implementation analyses although including different high level criteria in analysing electricity systems is common the literature is only starting to use formalised multi criteria decision making mcdm tools the review indicates that 63 of relevant articles favour renewable energy technologies for their given problems frequently mentioned success factors for electrification in sub saharan africa include adequate policy design sufficient finance and favourable political conditions while considerable regional and methodological literature gaps are apparent the literature in this review identifies a rich and fruitful ground for future research to fill these gaps

dynamic demand for residential electricity in taiwan under seasonality and increasing block pricing abstract this paper studies the dynamic demand for residential electricity in taiwan employing a monthly panel data set composed of 19 counties and spanning the period from 2007 01 to 2013 12 the partial adjustment model used addresses the endogeneity of the electricity price that results from the increasing block pricing the estimated results show that there is a significant seasonal difference in the demand for electricity between the summer and non summer periods both the adjustment speed and own price elasticity during the summer months are found to be lower than those in the non summer months due to the hot weather in summer it is easier for consumers to adjust their electricity consumption in response to the changes in electricity pricing during the non summer time the estimated inelastic short run and long run income effects show that electricity is a necessity for consumers moreover the controversial electricity conservation policies are found to be ineffective measures for reducing electricity consumption in taiwan

understanding the demand side issues of international corruption in global business business organizations and their representatives frequently encounter corruption and may be the perpetrators victims or simply participants in such acts while international corruption has existed in multiple forms for several years many individuals companies nations and international organizations are currently attempting to reduce or eliminate corrupt acts because of their harmful effects on local economies and the quality of life of citizens several of these corruption curtailment efforts have been directed toward the supply side of corruption i e those who make corrupt payments in developing an understanding of corruption however and formulating strategies for its reduction consideration must also be given to the demand side of corruption i e those who demand and accept corrupt payments accordingly this study examined the demand side of corruption and several related factors in the categories of government economy and poverty education geography and culture analysis of these factors employed the corruption perceptions index cpi formulated annually by transparency international ti and other sources several factors in each of the five categories were found to correlate significantly with perceived corruption and strategies for addressing these issues were developed and discussed

electricity demand for south korean residential sector abstract this study estimates the electricity demand function for the residential sector of south korea with the aim of examining the effects of improved energy efficiency structural factors and household lifestyles on electricity consumption in the study time series data for the period from 1973 to 2007 is used in a structural time series model to estimate the long term price and income elasticities and annual growth of underlying energy demand trend uedt at the end of the estimation period the result shows a long term income elasticity of 1 33 and a long term price elasticity of 0 27 with 0 93 as the percentage growth of uedt at the end of the estimation period this result suggests that in order to encourage energy efficiency in the residential sector the government should complement the market based pricing policies with non market policies such as minimum energy efficiency standards and public enlightenment

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

the demand for electricity in the gcc countries abstract cointegration techniques are used to study the effects of economic variables on electricity demand in the gcc countries a dynamic model is estimated using aggregate data for the six states spanning the period 1970 97 statistical investigations confirm the existence of unit root in all time series employed in the study which called for the use of cointegration and error correction methodologies empirical results indicate that both income and price have an impact on electricity consumption and income and price policies could be effectively facilitated in electricity demand management

elasticities of electricity demand in urban indian households abstract in the past several electricity demand studies have been published for india based on aggregate macro data at the country or sub national state level since the underlying theory of consumer demand is based on the behaviour of individual agents the use of micro data which reflects individual and household behaviour more closely can shed greater light on the nature of consumer responses in this paper seasonal price and income elasticities of electricity demand in the residential sector of all urban areas of india are estimated for the first time using disaggregate level survey data for about 30 000 households three electricity demand functions have been econometrically estimated using monthly data for the winter monsoon and summer season in order to understand the extent to which factors like income prices household size and other household specific characteristics influence variations observed in individual households electricity demand the results show electricity demand is income and price inelastic in all three seasons and that household demographic and geographical variables are significant in determining electricity demand

analysing households responsiveness towards socio economic determinants of residential electricity consumption in singapore abstract the research of household electricity use is still relatively new for singapore where apart from some government surveys and sparingly available papers not much has been done to understand the underlying socio economic determinants that affect residents energy demand here we seek to quantify price and income elasticities as well as provide reasonable justification for price asymmetry in singapore using a panel approach across dwelling types and geographical areas we find that households do not react much to prices and that price elasticities may decrease as income rises there is also some evidence of price asymmetry with surprising results putting responsiveness towards price decreases larger than price increases this points towards similar behavioural patterns with the rebound effect for household energy efficiency if found present in future studies our findings suggest that there will only be positive responses towards dynamic pricing and higher churn rates if more transparent information is provided on related cost savings when households are exposed to retail choice in the electricity market after full retail competition is introduced in 2018 in addition a large role will have to come from cultivating the young to engage in sustainable practices to achieve energy efficiency targets

change in consumer sensitivity to electricity prices in response to retail deregulation a panel empirical analysis of the residential demand for electricity in the united states abstract about ten years have passed since the deregulation of the u s retail electricity market and it is now generally accepted that the available data is adequate to quantitatively assess and compare conditions before and after deregulation this study therefore estimates the changes in price elasticity in the residential electricity market to examine the changes if any in household sensitivity as a result of retail electricity market deregulation policies to residential electricity rates specifically six types of panel data are prepared based on three cross sections all states except for alaska and hawaii and the district of columbia deregulated states and non deregulated states and two time series the period before deregulation and the period after deregulation the panel empirical analysis techniques are used to determine whether or not the variables are stationary and to estimate price elasticity we find that there is no substantial difference in the price elasticity between deregulated and non deregulated states for both periods before deregulation and after deregulation thus it can be said that the deregulation of the retail electricity market has not made consumers more sensitive to electricity rates and that retail deregulation policies are not the cause of price elasticity differences between deregulated and non deregulated states

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

estimation of residential electricity demand function in seoul by correction for sample selection bias abstract this paper attempts to estimate the residential electricity demand function in seoul to this end we collected the data from a survey of households in seoul and employed the bivariate model to rectify the undesirable impacts of non response data the results show that the size of family the size of house dummy for having a plasma display panel television dummy for having an air conditioner and the household s income have positive relationships with the residential electricity demand on the other hand electricity price contributes negatively to the residential electricity demand in addition the price and income elasticities were estimated as 0 2463 and 0 0593 respectively implying that residential electricity demand in seoul is price and income inelastic such useful information is expected to help policy makers regulate the residential electricity supply and predict the effect of the price on the residential electricity demand in the future

electricity consumption in g7 countries a panel cointegration analysis of residential demand elasticities this article applies recently developed panel unit root and panel cointegration techniques to estimate the long run and short run income and price elasticities for residential demand for electricity in g7 countries the panel results indicate that in the long run residential demand for electricity is price elastic and income inelastic the study concludes that from an environmental perspective there is potential to use pricing policies in the g7 countries to curtail residential electricity demand and thus curb carbon emissions in the long run

elasticities of electricity demand in india abstract the paper examines econometric relationship between electricity consumption and variables like income price of electricity and diesel used in for captive power generation to meet the shortages and reliability of power supply from utilities in five major consumer categories in india these categories are residential commercial agriculture small and medium industries and large industries income and price elasticities of electricity consumption are estimated at the national level for these consumers by pooling data across 19 states spread over 9 years 1985 86 1993 94 the results show that electricity consumption in commercial and large industrial sectors are income elastic 1 while residential agricultural and small and medium industries are income inelastic

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

residential demand for electricity the case of greece this paper examines the determinants of residential electricity consumption in greece over the period 1961 86 the paper presents first a brief description of the evolution of residential electricity consumption then it proceeds in the estimation of elasticities of residential demand for electricity using a single equation model with the ridge regression method the paper concludes that i the residential demand for electricity is price inelastic and income elastic ii there is high substitutability between electricity and lpg iii during the examined period the number of consumers played a very important role in the expansion of electricity consumption in greece and iv there is no regional variation in residential electricity demand

the welfare effects of unprecedented electricity price hikes in zambia abstract this paper simulates the real household expenditure effects of large electricity price increases in zambia first we find that electricity subsidies are highly regressive the richest household quintile receives over 60 of the subsidies while the poorest quintile receives less than 1 second our partial equilibrium simulations of the welfare effects of a 75 electricity price increase show that the poorest households would experience a 3 times larger percentage loss in real expenditure compared to the wealthiest households naturally these adverse effects lead to an increase in poverty however we find that transferring the fiscal savings realised from the complete elimination of electricity subsidies to the poor reduces extreme poverty significantly this budget neutral strategy is particularly attractive for zambia and other sub saharan economies currently battling the twin challenges of widening budget deficits and high extreme poverty

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

why bank credit policies fluctuate a theory and some evidence in a rational profit maximizing world banks should msdntain a credit policy of lending if and only if borrowers have positive net present value projects why then are changes in credit policy seemingly correlated with changes in the condition of those demanding credit this paper argues that rational bank managers with short horizons will set credit policies that influence and are influenced by other banks and demand side conditions this leads to a theory of low frequency business cycles driven by bank credit policies evidence from the banking crisis in new england in the early 1990s is consistent with the assumptions and predictions of the theory

the demand for electricity in israel quarterly data for israel are used to compare and contrast three dynamic econometric methodologies for estimating the demand for electricity by households and industrial companies these are the dynamic regression model and two approaches to cointegration ols and maximum likelihood since we find evidence of seasonal unit roots in the data we also test for seasonal cointegration we find that the scale elasticities are similar in all three approaches but the ols price elasticities are considerably lower moreover ols suggests non cointegration the paper concludes by stochastically simulating the drms to calculate upside risk in electricity demand

the residential demand for electricity in australia an application of the bounds testing approach to cointegration this paper reports estimates of the long and short run elasticities of residential demand for electricity in australia using the bounds testing procedure to cointegration within an autoregressive distributive lag framework in the long run we find that income and own price are the most important determinants of residential electricity demand while temperature is significant some of the time and gas prices are insignificant our estimates of long run income elasticity and price elasticity of demand are consistent with previous studies although they are towards the lower end of existing estimates as expected the short run elasticities are much smaller than the long run elasticities and the coefficients on the error correction coefficients are small consistent with the fact that in the short run energy appliances are fixed

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

demand customer base line and demand response in the electricity market a survey the increasing use of demand side management as a tool to reliably meet electricity demands at peak time has stimulated interest among researchers consumers and producer organiza tions managers regulators and policymakers this research reviews the growing literature on models which are used to study demand customer base line cbl and demand response in the electricity market after characterizing the general demand models the cbl based on which the demand response models are studied is reviewed given the experience gained from the review and existing conditions the study combines an appropriate model for each case for a possible application to the electricity market moreover it discusses the implications of the results in the literature these aspects are studied independently the main contribution of this survey is attributed to the treatment of the three issues as sequentially interdependent the review is expected to enhance the understanding of the demand cbl and demand response in the electricity market and their relationships the objective is conducted through a combination of demand and supply side managements in order to reduce demand through different demand response programs during peak times this enables electricity suppliers to save costly electricity generation and at the same time reduce energy vulnerability
