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

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

the non linear link between electricity consumption and temperature in europe a threshold panel approach this paper investigates the relationship between electricity demand and temperature in the european union we address this issue by means of a panel threshold regression model on 15 european countries over the last two decades our results confirm the non linearity of the link between electricity consumption and temperature found in more limited geographical areas in previous studies by distinguishing between north and south countries we also find that this non linear pattern is more pronounced in the warm countries finally rolling regressions show that the sensitivity of electricity consumption to temperature in summer has increased in the recent period

the finance growth nexus evidence from bank branch deregulation this paper provides evidence that financial markets can directly affect economic growth by studying the relaxation of bank branch restrictions in the united states we find that the rates of real per capita growth in income and output increase significantly following intrastate branch reform we also argue that the observed changes in growth are the result of changes in the banking system improvements in the quality of bank lending not increased volume of bank lending appear to be responsible for faster growth

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

cross subsidy in electricity tariffs evidence from india the recent reforms in india have been equated to the reduction of cross subsidization in electricity tariffs examining the usefulness of cross subsidies in electricity tariffs in india i have argued that they are prone to considerable inefficiencies and should be discontinued i have also formally examined the viability of above cost tariffs in the industrial sector to allow subsidized domestic and agricultural consumption finally i have used data from a distribution company in the state of uttar pradesh india to estimate industrial demand for electricity and have found that the policy of cross subsidy may have indeed gone overboard in india

modelling industrial energy demand in saudi arabia abstract between 1986 and 2016 industrial energy consumption in saudi arabia increased by tenfold making it one of the largest end use sectors in the kingdom despite its importance there appear to be no published econometric studies on aggregate industrial energy demand in saudi arabia we model aggregate industrial energy demand in saudi arabia using harvey s 1989 structural time series model showing that it is both price and income inelastic with estimated long run elasticities of 0 34 and 0 60 respectively the estimated underlying energy demand trend suggests improvements in energy efficiency starting from 2010 applying decomposition analysis to the estimated econometric equation highlights the prominent roles of the activity effect the growth in industrial value added and the structure effect the shift towards energy intensive production in driving industrial energy demand growth moreover the decomposition shows how exogenous factors such as energy efficiency helped mitigate some of that growth delivering cumulative savings of 6 8 million tonnes of oil equivalent mtoe between 2010 and 2016 saudi arabia implemented a broad energy price reform program in 2016 which raised electricity fuel and water prices for households and industry the decomposition results reveal that holding all else constant higher industrial energy prices in 2016 reduced the sector s energy consumption by 6 9 a decrease of around 3 0 mtoe saudi policymakers could therefore build on the current policy of energy price reform and energy efficiency standards to mitigate the rate of growth of industrial energy consumption increase economic efficiency and maintain industrial sector competitiveness

household and industrial electricity demand in europe abstract this paper examines the electricity demand and its determinants in 29 european countries during the liberalization of the electricity market based on panel data for these countries for the years 1995 2015 and using a dynamic partial adjustment model price elasticities are estimated for both residential and industrial electricity demand these elasticities and effects of other variables on electricity consumption are estimated using both gmm generalized method of moments and ml maximum likelihood approaches it is found that the price elasticities are very small especially in the short run while the income elasticities are relatively large especially for households and in the long run

does financial reform raise or reduce saving the effect of financial liberalization on private saving is theoretically ambiguous not only because the link between interest rate levels and saving is itself ambiguous but also because financial liberalization is a multidimensional and phased process sometimes involving reversals using principal components we construct 25 year time series indices of financial liberalization for each of eight developing countries chile ghana indonesia korea malaysia mexico turkey and zimbabwe these are employed in an econometric analysis of private saving in these countries our results cannot offer support for the hypothesis that financial liberalization will increase saving on the contrary the indications are that liberalization overall and in particular those elements that relax liquidity constraints may be associated with a fall in saving

short run and long run elasticities of import demand for crude oil in turkey abstract the aim of this study is to attempt to estimate the short run and the long run elasticities of demand for crude oil in turkey by the recent autoregressive distributed lag ardl bounds testing approach to cointegration as a developing country turkey meets its growing demand for oil principally by foreign suppliers thus the study focuses on modelling the demand for imported crude oil using annual data covering the period 1980 2005 the bounds test results reveal that a long run cointegration relationship exists between the crude oil import and the explanatory variables nominal price and income but not in the model that includes real price in domestic currency the long run parameters are estimated through a long run static solution of the estimated ardl model and then the short run dynamics are estimated by the error correction model the estimated models pass the diagnostic tests successfully the findings reveal that the income and price elasticities of import demand for crude oil are inelastic both in the short run and in the long run

integrated capacity and inventory management with capacity acquisition lead times we model a make to stock production system that utilizes permanent and contingent capacity to meet non stationary stochastic demand where a constant lead time is associated with the acquisition of contingent capacity we determine the structure of the optimal solution concerning both the operational decisions of integrated inventory and flexible capacity management and the tactical decision of determining the optimal permanent capacity level furthermore we show that the inventory either before or after production the pipeline contingent capacity the contingent capacity to be ordered and the permanent capacity are economic substitutes we also show that the stochastic demand variable and the optimal contingent capacity acquisition decisions are economic complements finally we perform numerical experiments to evaluate the value of utilizing contingent capacity and to study the effects of capacity acquisition lead time providing useful managerial insights

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

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

residential electricity demand dynamics in turkey abstract this article provides fresh empirical evidences for the income and price elasticies of the residential energy demand both in the short run and long run for turkey over the period 1968 2005 using the bounds testing procedure to cointegration the computed elasticities of income and price are consistent with the previous studies and as expected the long run elasticities are greater than the short run elasticities an augmented form of granger causality analysis is implemented among residential electricity income price and urbanization in the long run causality runs interactively through the error correction term from income price and urbanization to residential energy but the short run causality tests are inconclusive the parameter stability of the short run as well as long run coefficients in the residential energy demand function are tested the results of these tests display a stable pattern

the price elasticity of electricity demand in south australia abstract in this paper the price elasticity of electricity demand representing the sensitivity of customer demand to the price of electricity has been estimated for south australia we first undertake a review of the scholarly literature regarding electricity price elasticity for different regions and systems then we perform an empirical evaluation of the historic south australian price elasticity focussing on the relationship between price and demand quantiles at each half hour of the day this work attempts to determine whether there is any variation in price sensitivity with the time of day or quantile and to estimate the form of any relationships that might exist in south australia

modeling industrial energy demand in greece using cointegration techniques abstract this paper attempts to shed light on the determinants of industrial energy demand in greece for this purpose we used cointegration analysis in order to capture short run and long run elasticities for oil and electricity industrial demand respectively the sample spans the period 1970 2004 from the empirical analysis and the johansen s maximum likelihood procedure we found cointegration for oil and electricity demand the results suggest that industrial energy demand is inelastic both in the short and the long run while electricity and oil are substitutes also oil and electricity prices are weakly exogenous both in the short and the long run

long and short run elasticities of residential electricity consumption in china a partial adjustment model with panel data abstractwhile it has stabilized in developed world the per capita residential electricity consumption rec in developing countries such as china is growing very rapidly and this trend is very likely to continue built upon a provincial level panel data we employ a partial adjustment model to investigate the future trend of rec in china and factors that affect it we estimate the income and price short term and long term elasticities for urban and rural china respectively and compare the results with rec studies in other countries or regions the findings provide useful information to understand how the rec would grow in china as household income increases and how effective that price could be as an intervention tool

how do urban households in china respond to increasing block pricing in electricity evidence from a fuzzy regression discontinuity approach abstract china is the largest electricity consumption country after it has passed the united states in 2011 residential electricity consumption in china grew by 381 35 12 85 per annum between 2000 and 2013 in order to deal with rapid growth in residential electricity consumption an increasing block pricing policy was introduced for residential electricity consumers in china on july 1st 2012 using difference in differences models with a fuzzy regression discontinuity design we estimate a causal effect of price on electricity consumption for urban households during the introduction of increasing block pricing policy in guangdong province of china we find that consumers do not respond to a smaller approximately 8 increase in marginal price however consumers do respond to a larger increase in marginal price an approximately 40 increase in marginal price induces an approximately 35 decrease in electricity use 284 kw h per month our results suggest that although the increasing block pricing could affect the behavior of households with higher electricity use there is only a limit potential to overall energy conservation

income and price elasticities of electricity demand aggregate and sector wise analyses abstract cointegration and vector error correction modeling approaches are widely used in electricity demand analysis the study rigorously examines the determinants of electricity demand at aggregate and sectoral levels in pakistan in the backdrop of severe electricity shortages our empirical findings give support to the existence of a stable long run relationship among the variables and indicate that electricity demand is elastic in the long run to both income and price at aggregate level at sectoral level long run income and price elasticity estimates follow this pattern except in agricultural sector where electricity demand is found elastic to output but inelastic to electricity price on the contrary the coefficients for income and price are rather small and mostly insignificant in the short run we employed temperature index price of diesel oil and capital stock at aggregate and sectoral levels as exogenous variables these variables account for most of the variations in electricity demand in the short run it shows that mechanization of the economy significantly affect the electricity demand at macro level moreover elastic electricity demand with respect to electricity price in most of the sectors implies that electricity price as a policy tool can be used for efficient use and conservation

regional heterogeneous drivers of electricity demand in saudi arabia modeling regional residential electricity demand abstract this study investigates the drivers of residential electricity demand in saudi arabia at a regional level for the period 1990 2018 using structural time series modeling we find that saudi arabia s two waves of energy price reforms in 2016 and 2018 have had different impacts on residential electricity consumption across its regions the empirical estimation results show that the long run price responses of residential electricity demand vary across regions from 0 20 in the central region to 0 46 in the eastern region the short run elasticities are 0 10 for the central and western regions 0 15 in the southern region while the eastern region s demand does not respond to price changes in the short run the long run income elasticities of the regions residential electricity demand also differ considerably from 1 02 in the western region to 0 27 in the eastern region the short run income elasticities are 0 14 and 0 43 for the eastern and western regions respectively while the residential electricity demand in the central and southern regions does not react to income changes we further estimate that hot weather conditions significantly impact all regions residential electricity demand finally we find that all regions saw some efficiency improvements in light of the energy price reforms although there is a room for further improvements the findings of the study can be useful for policymakers through the ways that we discussed in the paper

modelling energy demand of developing countries are the specific features adequately captured abstract this paper critically reviews existing energy demand forecasting methodologies highlighting the methodological diversities and developments over the past four decades in order to investigate whether the existing energy demand models are appropriate for capturing the specific features of developing countries the study finds that two types of approaches econometric and end use accounting are commonly used in the existing energy demand models although energy demand models have greatly evolved since the early seventies key issues such as the poor rich and urban rural divides traditional energy resources and differentiation between commercial and non commercial energy commodities are often poorly reflected in these models while the end use energy accounting models with detailed sectoral representations produce more realistic projections as compared to the econometric models they still suffer from huge data deficiencies especially in developing countries development and maintenance of more detailed energy databases further development of models to better reflect developing country context and institutionalizing the modelling capacity in developing countries are the key requirements for energy demand modelling to deliver richer and more reliable input to policy formulation in developing countries

do customer information programs reduce household electricity demand the irish program abstract we study empirically the effectiveness of a customer information program to decrease energy demand by increasing efficient electricity use this demand side management dsm program aims at reducing the lack of information on the customers side that is documented in related literature we study the irish dsm program which is particularly well suited to investigate this issue as strategic behavior is ruled out in this setting for both customers and suppliers on the customers side because information programs allow only for a limited substitution of own effort on the producers side because the specificity of the irish case left no room for strategic behavior we find that providing customers with information reduced overall electricity demand by roughly 7 as well as reducing demand fluctuations over the year further we find that the dsm program had a larger impact upon long run demand with consumers short run demand behavior not being changed significantly

simultaneous capacity and production management of short life cycle produce to stock goods under stochastic demand this paper derives the optimal simultaneous capacity and production plan for a shortlife cycle produce to stock good under stochastic demand capacity can be reduced as well as added at exogenously set unit prices in both cases studied with and without carryover of unsold units a target interval policy is optimal there is a usually different target interval for each period such that capacity should be changed as little as possible to bring the level available into that interval our contribution in the case of no carry over is a detailed characterization of the target intervals assuming demands increase stochastically at the beginning of the life cycle and decrease thereafter in the case of carry over we establish the general result and show that capacity and inventory are economic substitutes the target intervals decrease in the initial stock level and the optimal unconstrained base stock level decreases in the capacity level in both cases optimal service rates are not necessarily constant over time a numerical example illustrates the results

the real time price elasticity of electricity the real time price elasticity of electricity contains important information on the demand response of consumers to the volatility of peak prices despite the importance empirical estimates of the real time elasticity are hardly available this paper provides a quantification of the real time relationship between total peak demand and spot market prices we find a low value for the real time price elasticity which may partly be explained from the fact that not all users observe the spot market price if we correct for this phenomenon we find the elasticity to be fairly low for consumers currently active in the spot market if this conclusion applies to all users this would imply a limited scope for government intervention in supply security issues

managing flexible capacity in a make to order environment flexible capacity has been shown to be very effective to hedge against forecast errors at the investment stage in a make to order environment this flexibility can also be used to hedge against variability in customer orders in the short term for that purpose production levels must be adjusted each period to match current demands to give priority to the higher margin product or to satisfy the closest customer however this will result in swings in production inducing larger order variability at upstream suppliers and significantly higher component inventory levels at the manufacturer through a stylized two plant two product capacitated manufacturing setting we show that the performance of the system depends heavily on the allocation mechanism used to assign products to the available capacity although managers would be inclined to give priority to higher margin products or to satisfy customers from their closest production site these practices lead to greater swings in production result in higher operational costs and may reduce profits

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

a review of time use models of residential electricity demand residential electricity demand in most european countries accounts for a major proportion of overall electricity consumption the timing of residential electricity demand has significant impacts on carbon emissions and system costs this paper reviews the data and methods used in time use studies in the context of residential electricity demand modelling it highlights key issues which are likely to become more topical for research on the timing of electricity demand following the roll out of smart metres

the demand for energy in the uk a general equilibrium analysis abstract previous research into the demand for energy has treated economic activity as an explanatory variable however economic theory suggests that economic activity is not independent of energy prices and energy demand we explore the two way causality between energy demand and economic activity in the context of a macroeconometric model of the uk economy inter alia this study suggests that the demand for energy is more price elastic in general equilibrium than it is under the more conventional assumptions of partial equilibrium

estimation of elasticities for electricity demand in brazilian households and policy implications abstract this paper aims to identify the demand elasticity in energy consumption by brazilian families by using an original household level sample we are the first to identify the average price and income elasticities for brazil we also investigate heterogeneous effects across different quantiles through a quantile regression qr analysis finally we extend the results of the qr analysis and combine them with aggregated data to assess the effects of two price policies a cross subsidy and the recently adopted tariff flags the primary data comes from the household budget survey pof for two periods 1998 99 and 2008 13 conducted in the metropolitan area of sao paulo the price and income elasticities range from 0 46 to 0 56 and from 0 20 to 0 32 respectively the qr results indicate that households behavioral response to a price increase is non uniform across groups and that the reaction is stronger for the lower quantiles additionally tariff flags lead to a more significant reduction in consumption for the low income residences therefore representing a regressive policy on the other hand a cross subsidy that increases the energy price to ordinary residences by 1 could mean a decrease in electricity prices of between 7 5 and 12 4 to low income families

price freezes durables and residential electricity demand evidence from greater buenos aires abstract this paper examines the determinants of residential electricity demand in greater buenos aires between 1997 and 2006 during the second half of this period residential electricity tariffs remained nominally fixed while rising incomes increased sales of durables our study is one of few that use monthly data to examine the contribution of prices to residential consumption growth and it appears to be the first time series study to explicitly consider the impact of air conditioners on residential demand results indicate that durables have an impact on residential electricity demand simulations illustrate how prices income and durables impact future demand

which utilization and service level lead to the maximum eva abstract in this paper a model for evaluating the influence of utilization wip fgi service level and production lead time on eva economic value added is developed in order to link the available logistical key figures with a market perspective and discuss their influence on company value the question answered in this paper is what is the optimal utilization and service level of a production system in order to achieve the maximum possible eva for a company a single product single machine make to order production system with investment dependent machine capacity is modeled the model combines a market share concept based on delivery production lead time and service level with concepts describing the logistical relationships between wip utilization production lead time and service level in addition to the explanatory use of the model it can provide support for strategic decisions concerning investing or divesting machinery the main application of this model is in describing the link between capacity investment and company value comprehensively based on data available from cost accounting in real companies furthermore this paper shows that high flexibility of personnel and machine capacity increases the maximum possible eva of production systems even if this flexibility is linked to additional costs

are shocks to energy consumption permanent or temporary evidence from 182 countries this article applies univariate and panel data unit root tests to annual panel data for 182 countries over the period 1979 2000 to examine the stationarity properties of per capita energy consumption the univariate unit root test can only reject the unit root null for 56 countries or 31 of the sample at the 10 level or better however univariate unit root tests have low power with short spans of data and therefore failure to reject the unit root null should be treated with caution when we apply the panel data unit root test we find overwhelming evidence that energy consumption is stationary we discuss the policy implications of these findings and offer suggestions for future research

estimation of urban residential electricity demand in china using household survey data abstract this paper uses annual urban household survey data of sichuan province from 2007 to 2009 to estimate the income and price elasticities of residential electricity demand along with the effects of lifestyle related variables the empirical results show that in the urban area of sichuan province the residential electricity demand is price and income inelastic with price and income elasticities ranging from 0 35 to 0 50 and from 0 14 to 0 33 respectively such lifestyle related variables as demographic variables dwelling size and holdings of home appliances are also important determinants of residential electricity demand especially the latter these results are robust to a variety of sensitivity tests the research findings imply that urban residential electricity demand continues to increase with the growth of income the empirical results have important policy implications for the multistep electricity price which been adopted in some cities and is expected to be promoted nationwide through the installation of energy efficient home appliances

short and long run electricity demand elasticities at the subsectoral level a cointegration analysis for german manufacturing industries in this paper we use multivariate cointegration analysis to estimate electricity demand elasticities at the subsectoral industry level this enables us to reap the benefits of lower heterogeneity within the electricity consuming sectors investigated and of retaining additional information otherwise blurred by aggregation the annual data set used covers eight subsectors of the german economy for the period 1970 2007 by employing a cointegrated var model specification and accounting for structural breaks we find cointegration relationships for five of the eight subsectors studied the long run elasticities range between 0 70 and 1 90 for economic activity and between 0 52 and zero for the price of electricity the short run elasticities are estimated by single equation error correction modeling and found to be between 0 17 to 1 02 for economic activity and 0 57 to zero for electricity price granger causality tests indicate that in the long term causality runs from both economic activity and electricity price to electricity consumption while granger causality from electricity price and electricity consumption to economic activity is detected in only two subsectors electricity price is found to be granger caused neither in the long nor the short run finally an impulse response analysis yields plausible results confirming the usefulness of the approach adopted

household demand for electricity the role of market distortions and prices in competition policy abstract this paper examines residential demand for electricity in sri lanka using survey data collected over a five year period between 2011 and 2015 the study finds that the major determinants of demand for residential electricity are the result of price or market distortions i e subsidies socioeconomic variables and energy saving technology the effects of these variables are particularly relevant to competition policy estimated elasticities with respect to average price subsidies under marginal cost pricing subsidies under average cost pricing and income are found to be 0 015 0 021 0 036 and 0 046 respectively we find that demand for electricity is inelastic and is categorised as a normal good however elasticities with respect to subsidy variables are found to be higher than the price variable this implies that under an increasing block rate system any price change used as a policy measure to control electricity consumption will not be effective this is because price changes could alter the subsidy received by the consumer and therefore reverse the objective of the price change further results of this study find that price and elasticities with respect to subsidy variables are relatively higher for low income groups while income elasticity is relatively larger for high income groups

regionally varying and regionally uniform electricity pricing policies compared across four usage categories the objective of our research is to predict how electricity demand varies spatially between status quo regionally uniform electricity pricing and hypothetical regionally varying electricity pricing across usage categories we summarize the empirical results of a case study of electricity demand in south korea with three key findings and their related implications first the price elasticities of electricity demand differ across usage categories specifically electricity demands for manufacturing and retail uses are price inelastic and close to unit elastic respectively while those for agricultural and residential uses are not statistically significant this information is important in designing energy policy because higher electricity prices could reduce electricity demands for manufacturing and retail uses resulting in slower growth in those sectors second spatial spillovers in electricity demand vary across uses understanding the spatial structure of electricity demand provides useful information to energy policy makers for anticipating changes in demand across regions via regionally varying electricity pricing for different uses third simulation results suggest that spatial variations among electricity demands by usage category under a regionally varying electricity pricing policy differ from those under a regionally uniform electricity pricing policy differences in spatial changes between the policies provide information for developing a realistic regionally varying electricity pricing policy according to usage category

trade off between capacity invested and inventory needed a multi item capacitated make to order production system with considerable demand fluctuations is discussed the relationship between the available capacity and the inventory needed to meet customer requirements with a pre defined service level is modeled furthermore the total cost for both capacity and inventory is minimized and it is shown that assuming negligible change over times the double of the surplus inventory cost has to be equal to the excess capacity cost to ensure minimum total cost

estimation of elasticity price of electricity with incomplete information abstract the sharp increase in energy prices and growing concern for environmental issues among other things are behind the renewed interest in energy demand estimation however there is scarce academic literature that takes real situation of energy suppliers into account high quality but incomplete data in this paper we propose a useful and rather simple instrument for estimating electricity demand with the incomplete and or imperfect data currently available to suppliers in particular using real expenditure and consumption data on electricity we employ a model of random effects for panel data to estimate residential and industrial electricity demand in spain

estimation of the effects of price on apartment water demand using cointegration and error correction techniques abstractwater price is a key instrument in regulating water demand in the residential sector many empirical studies have assessed the effects of price through quantifying the price elasticity of water demand however most of these studies have mainly focused on the single family housing rather the multifamily housing an in depth understanding of the price elasticity of multifamily housing water demand is paramount for water planners in order to properly manage water use in the fast growing intensive housing developments in urban areas this study investigates both the long term and short term price elasticities of water demand in the residential apartments in auckland central city using 6 years of monthly time series data the price elasticities were estimated through cointegration and error correction methods the results showed that the price elasticities of water demand were 0 14 and 0 12 in the short term and the long term respectively the price is inelastic yet negative and statistically sign

testing viability of cross subsidy using time variant price elasticities of industrial demand for electricity indian experience abstract indian electric tariffs are characterized by very high rates for industrial and commercial classes to permit subsidized electric consumption by residential and agricultural customers we investigate the viability of this policy using monthly data for 1997 2003 on electric consumption by a few large industrial customers under the aegis of a small distribution company in the state of uttar pradesh for a given price cost ratio it can be shown that if the cross subsidizing class electricity demand is sufficiently elastic increasing the class rates fail to recover incremental cross subsidy necessary to support additional revenues for subsidized classes this suboptimality is tested by individually estimating time variant price elasticities of demand for these industrial customers using box cox and linear regressions we find that at least for some of these customers cross subsidy was suboptimal prior to as late as october 2001 when rates were changed following reforms

energy consumption and economic activity in industrialized countries the dynamic aggregate time series relationship abstract most econometric studies suggest that the income elasticity of demand for energy is approximately unity for the developed market economies it is shown that over the period 1950 1978 the long run income elasticity is substantially higher than unity in terms of a ces energy demand function this result reflects the application of a generalized dynamic estimation methodology where serial correlation is regarded as a diagnostic guide to distributed lag fitting price elasticities are also estimated but these are in line with conventional estimates

market power and heterogeneous pass through in german electricity retail abstract we analyze the pass through of cost changes to retail tariffs in the german electricity market over the 2007 2014 period we find an average pass through rate of around 60 this significantly varies with demand factors while the pass through rate to baseline tariffs where firms have greater market power because customers are less willing to switch is only 50 it increases to 70 in the competitive segment of the market although the pass through rate of independent firms is significantly higher than that of other firms in the competitive market segment the extent of supply side heterogeneity is limited thus the firms ability to exercise market power and reduce pass through appears to be constrained by competition and largely determined by demand side factors finally we find that the pass through rate in the competitive market segment has been approaching unity over the past years indicating a rise in competitive pressure

has latin america s post reform growth been disappointing after years of poor economic performance many latin american countries undertook ambitious programs of macroeconomic stabilization and structural reform in recent years this change in policy created high expectations for the region and some observers have questioned whether actual growth outcomes have lived up to these expectations the authors offer evidence that the response of economic growth to reforms in latin america has not been disappointing because of their significant policy changes and despite a global slowdown latin america did well to return to its historic growth rate of 2 percent per capita in 1990 93 latin america has responded to changes in policy variables as would have been predicted by the experience of other times and places those earlier experiences are summarized by a panel regression spanning many countries and multi year periods from 1960 to 1993 to get consistent estimates of the parameters linking growth and policy variables the authors use a dynamic panel methodology that both controls for unobserved time and country specific effects and accounts for the likely internal dynamism of the explanatory variables

a coordinated production planning model with capacity expansion and inventory management motivated by a problem faced by a large manufacturer of a consumer product we explore the interaction between production planning and capacity acquisition decisions in environments with demand growth we study a firm producing multiple items in a multiperiod environment where demand for items is known but varies over time with a long term growth and possible short term fluctuations the production equipment is characterized by significant changeover time between the production of different items while demand growth is gradual capacity additions are discrete therefore periods immediately following a machine purchase are characterized by excess machine capacity we develop a mathematical programming model and an effective solution approach to determine the optimal capacity acquisition production and inventory decisions over time through a computational study we show the effectiveness of the solution approach in terms of solution quality and investigate the impact of product variety cost of capital and other important parameters on the capacity and inventory decisions the computational results bring out some key insights increasing product variety may not result in excessive inventory and even a substantial increase in set up times or holding costs may not increase the total cost over the horizon in a significant manner due to the ability to acquire additional capacity we also provide solutions and insights to the real problem that motivated this work

finance and the sources of growth the authors evaluate whether the level of development in the banking sector exerts a causal impact on economic growth and its sources total factor productivity growth physical capital accumulation and private saving they use 1 a pure cross country instrumental variable estimator to extract the exogenous component of banking development and 2 a new panel technique that controls for country specific effects and endogeneity they find that banks do exert a large causal impact on total factor productivity growth which feeds through to overall gdp gross domestic product growth the long run links between banking development and both capital growth and private savings are more tenuous

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 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
