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

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

fuel demand elasticities for energy and environmental policies indian sample survey evidence india has been running large scale interventions in the energy sector over the last decades still there is a dearth of reliable and readily available price and income elasticities of demand to base these on especially for domestic use of traditional fuels this study uses the linear approximate almost ideal demand system la aids using micro data of more than 100 000 households sampled across india the la aids model is expanded by specifying the intercept as a linear function of household characteristics marshallian and hicksian price and expenditure elasticities of demand for four main fuels are estimated for both urban and rural areas by different income groups these can be used to evaluate recent and current energy policies the results can also be used for energy projections and carbon dioxide simulations given different growth rates for different segments of the indian population

household electricity demand revisited respond to price changes this paper develops a model for evaluating the effects of alternative tariff designs on electricity use the model concurrently addresses several interrelated difficulties posed by nonlinear pricing heterogeneity in consumer price sensitivity and consumption aggregation over appliances and time we estimate the model using extensive data for a representative sample of 1300 california households the results imply a strikingly skewed distribution of household electricity price elasticities in the population with a small fraction of households accounting for most aggregate demand response we then estimate the aggregate and distributional consequences of recent tariff structure changes recent efforts to restructure electricity markets have renewed interest in electricity demand and pricing this interest reflects a broad desire to improve the efficiency of electricity markets and policy makers concerns over the impact of price changes on consumers how new pricing mechanisms would affect households consumption and expenditures is a matter of considerable uncertainty however this uncertainty has provoked controversy and debate in the regulatory policy arena hampering market reforms using econometric methods to assess the effects of electricity price changes presents several challenges these include the nonlinear structure of tariff schedules aggregation of metered consumption behaviour over time and appliances and the interdependence of energy use with longer term household decisions over appliance ownership and dwelling characteristics the first two issues introduce complex simultaneity problems between marginal prices and consumption the third issue imposes high data requirements information on household specific appliance holdings and residence features and creates heterogeneity in consumption responses related to the characteristics of these durable goods when the researcher s objective is to develop a model for simulating the effects of prospective tariff changes ignoring these issues will provide an incomplete assessment of demand responses and potentially misleading predictions of a new tariff s consumption and revenue consequences in this paper we estimate a model of household electricity demand that can be used

zero expenditures and the estimation of engel curves over the brief interview periods typical of budget surveys such as the u k family expenditure survey households recorded expenditures are liable to be misleading indicators of their underlying consumption most starkly a household may not be observed to purchase commodities that it nevertheless consumes this paper considers the implications of such measurement errors for the estimation of demand systems and derives a consistent estimator for the special case of linear engel curves

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

short and long run demand for energy in mexico a cointegration approach abstract the objective of this paper is to estimate the demands for the different types of energy consumption for the mexican economy over the period 1965 2001 these demands are modeled as a function of output and the own real price the johansen j econ dynamics control 12 1988 231 procedure and the likelihood ratio tests indicate the existence of long run and stable relationships between each type of energy demand and income with the exception of the industrial sector where the cointegrating vector also includes the relative prices the weak exogeneity tests indicate that energy consumption and income do not reject the null hypothesis of weak exogeneity when relative prices are weak exogenous the final econometric models show that relative prices in the short run are relevant in all cases with the exception of the residential sector these results indicate that in mexico the demand for energy is fundamentally driven by income and that the effect of the relative prices is basically concentrated on the short run with the exception of the industrial sector which also shows a long term price impact the strong dependence of energy consumption with respect to income and the price inelastic response indicates that it is necessary to introduce strong measures to decouple energy consumption from output in order to obtain sustainable economic growth in mexico

demand for gasoline in kuwait an empirical analysis using cointegration techniques abstract this paper estimates the demand for gasoline in kuwait for the period 1970 1989 using a cointegration and error correction model ecm it is found that gasoline demand is inelastic with respect to price in the short and long run and while it is elastic in the long run gasoline demand is inelastic with respect to income in the short run this suggests that gasoline demand response to income changes is higher in the long run than in the short run furthermore gasoline consumption adjusts towards its long run level with about 52 of the adjustment occurring in the first year

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 the transportation sector of mexico abstract this paper report results of an analysis of the demand for energy in the mexican transport sectors focusing on the railroad air transport and motor vehicle modes the approach is an econometric one with emphasis placed on the structure for each mode for two of the modes a two stage approach is employed where in the first stage demands for services from the particular mode are modeled and in the second stage demand is treated as a derived demand from these transport services for the motor vehicle mode gasoline demand is considered as the product of gasoline consumption per vehicle times the total number of vehicles and then these components are related to economic and structural variables diesel demand of motor vehicles is modeled in a more reduced from approach the principal finding is that changes in income play a more important role in affecting energy demand than do changes in energy prices especially in the railroad and air transport sectors for the gasoline and diesel fuel demand in the monitor vehicle sector however price is of substantial importance

household electricity end use consumption results from econometric and engineering models information about total electricity consumption is available for most households however the electricity consumption related to different end uses e g space heating lighting and services from household appliances are usually not metered metering data are costly to achieve and in this paper we study two methods for end use estimation which can be applied on household data for appliance holdings demographic and economic variables the first method is the engineering model which has been used to calculate the so far only documented norwegian end use results applied on data from a norwegian energy survey the second method is an econometric conditional demand model applied on data from the same survey we compare the numerical results from the two models and give some recommendations regarding choice of end use approach and what questions to implement in household surveys designed to disaggregate electricity consumption

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

on the possibility of an inverse relationship between tax rates and government revenues abstract when arthur laffer and other supply side advocates plot total tax revenue as a function of a particular tax rate they draw an upward sloping segment called the normal range followed by a downward sloping segment called the prohibitive range a brief literature review indicates that tax rates on the prohibitive range in theoretical and empirical models have been the result of particularly high tax rates high elasticity parameters or both the labor tax rate which maximizes total revenue for example will depend on the assumed labor supply elasticity this paper introduces a new curve which summarizes the tax rate and elasticity combinations that result in maximum revenues separating the normal area from the prohibitive area a general purpose empirical u s general equilibrium model is used to plot the laffer curve for several elasticities and to plot the newly introduced curve using the labor tax example results indicate that the u s could conceivably be operating in the prohibitive area but that the tax wedge or labor supply elasticity would have to be much higher than most estimates would suggest

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

an analysis of gasoline demand elasticities at the national and local levels in mexico abstract the majority of evidence on gasoline demand elasticities is derived from models based on national data since the largest growth in population is now taking place in cities in the developing world it is important that we understand whether this national evidence is applicable to demand conditions at the local level the aim of this paper is to estimate and compare gasoline per vehicle demand elasticities at the national and local levels in mexico national elasticities with respect to price income vehicle stock and metro fares are estimated using both a time series cointegration model and a panel gmm model for mexican states estimates for mexico city are derived by modifying national estimates according to mode shares as suggested by graham and glaister 2006 and by estimating a panel within groups model with data aggregated by borough although all models agree on the sign of the elasticities the magnitudes differ greatly elasticities change over time and differ between the national and local levels with smaller price responses in mexico city in general price elasticities are smaller than those reported in the gasoline demand surveys a pattern previously found in developing countries the fact that income and vehicle stock elasticities increase over time may suggest that vehicles are being used more intensively in recent years and that mexico city residents are purchasing larger vehicles elasticities with respect to metro fares are negligible which suggests little substitution between modes finally the fact that fuel efficiency elasticities are smaller than vehicle stock elasticities suggests that vehicle stock size rather than its composition has a larger impact on gasoline consumption in mexico city

household energy demand in kenya an application of the linear approximate almost ideal demand system la aids abstract this paper estimates price and fuel expenditure elasticities of demand by applying the linear approximate almost ideal demand system la aids to 3665 households sampled across kenya in 2009 the results indicate that motor spirit premium msp automotive gas oil ago and lubricants are price elastic while fuel wood kerosene charcoal liquefied petroleum gas lpg and electricity are price inelastic kerosene is income elastic while fuel wood charcoal lpg electricity msp and ago are income inelastic the results also reveal fuel stack behaviour that is multiple fuel use among the households main policy implications of the results include increasing the penetration of alternative fuels as well as provision of more fiscal incentives to increase usage of cleaner fuels this not withstanding however the household income should be increased beyond a certain point for the household to completely shift and use a new fuel

residential electricity demand in spain new empirical evidence using aggregate data this paper presents an empirical analysis on residential demand for electricity this analysis has been performed using aggregate panel data at the province level for 47 spanish provinces for the period from 2000 to 2008 for this purpose we estimated a log log demand equation for electricity consumption using a dynamic partial adjustment approach this dynamic demand function has been estimated using a two step system gmm estimator proposed by blundell and bond 1998 the purpose of this empirical analysis is to highlight some of the characteristics of spanish residential electricity demand particular attention has been paid to the influence of price income and weather conditions on electricity demand the estimated short and long run own price elasticities are negative as expected but lower than 1 furthermore weather variables have a significant impact on electricity demand

short and long run elasticities in us residential electricity demand a co integration approach abstract co integration techniques show promise in the analysis of short and long run effects of economic variables on energy use we use these techniques to develop an error correction model of annual us residential electricity demand we construct equipment stock indices and estimate the model for 1949 1993 our analysis suggests a structural shift in consumption during the 1960s we discuss reasons for this shift report the short and long run elasticities provide forecasts for 1994 1995 and compare the model s forecasts with other published forecasts

price elasticities policy measures and actual developments in household energy consumption a bottom up analysis for the netherlands in the netherlands it seems likely that the large number of new policy measures in the past decade has influenced the response of households to changing prices to investigate this issue the energy trends in the period 1990 2000 have been simulated with a bottom up model applied earlier for scenario studies and extensive data from surveys for a number of alternative price cases the elasticity values found are explained using the bottom up changes in energy trends one finding is that the specific set of saving options defines for a great part the price response the price effect has been analysed too in combination with the policy measures standards subsidies and energy taxes the simulation results indicate that the elasticity value could be 30 40 higher without these measures

swedish tax rates labor supply and tax revenues effective marginal tax rates on labor income for the representative swede have increased from roughly 50 percent in 1959 to 80 percent today the effects of this increase in the level of taxation are examined using a two sector model parameterized to correspond to the swedish economy the model contains a single household which allocates labor to either taxed essentially market or untaxed largely household uses the estimated long run effects are sufficient to explain up to 75 percent of the recent decline in the measured growth rate of the swedish gnp calculations of total tax revenues are also derived from the model these peak when the tax rate is approximately 70 percent indicating that sweden is presently on the downward sloping portion of its laffer curve

distributional effects of subsidy removal and implementation of carbon taxes in mexican households abstract this paper presents a microsimulation using data from the national households income and expenditure survey nhies from 1994 to 2010 to determine the distributional effects of the price changes arising from energy and environmental policies and their impact on mexican households we reported simulations of several changes in energy prices as a result of partial or total energy subsidy removal including carbon tax in order to examine whether the subsidy mechanism and carbon tax tend to be progressive or regressive we evaluated the households burden in different income levels these simulations respond to the need for an assessment of economic and environmental impacts of energy subsidies in mexico this is of great importance for mexico because of effort that has been taken in the development of energy policies and the rising interest of the mexican government in mitigating carbon dioxide co2 emissions and their concomitant environmental damage

underlying trends and seasonality in uk energy demand a sectoral analysis this paper demonstrates the importance for energy demand modelling of allowing for trends and seasonal effects that are stochastic in form inherent underlying trends may be non linear and reflect not only technical progress which usually produces greater energy efficiency but also other factors such as changes in consumer tastes and the economic structure that may be working in the opposite direction using quarterly unadjusted data for various sectors in the uk it is shown that unless energy demand models are formulated so as to allow for stochastic trends and seasonals estimates of price and income elasticities could be seriously biased

the unprofitability of mixed strategy equilibria in two person games abstract in this paper it is demonstrated that the payoffs of mixed strategy equilibria are equal to the maximin values for all 2x2 matrix games if maximim implies completely mixed strategies this characterizes a subclass of unprofitable games maximin instead of nash equilibrium has been suggested as an appropriate solution concept for these games

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

rationing can backfire the day without a car in mexico city a ban restricting each car from driving on a specified weekday is found to have increased total driving in mexico city because of the ban cars effectively represent driving permits and some households have bought an additional car and increased their driving greater use of old cars congestion effects and increased weekend driving may also have contributed to the disappointing results the ban has high welfare costs and does not deliver the intended benefits of reduced driving quite the contrary the experience provides an interesting lesson in applied welfare economics theory indicates that this is a costly way of reducing traffic and pollution but the finding that the strategy is counterproductive could be made only with applied quantitative analysis in november 1989 the mexico city administration imposed a regulation banning each car from driving a specific day of the week called hoy no circula this one does not circulate today the day without a car regulation specifies that cars with license plate numbers ending with digits 0 or 1 do not drive on monday 2 or 3 do not drive on tuesday and so on restrictions do not apply on weekends the regulation applies to all cars except those of the fire department and thus to firms as well as households we use the term household for simplicity compliance is generally believed to be high the police are visible and fines are heavy the regulation has been both popular and controversial some people argue that it places a reasonable burden on car owners in order to alleviate congestion and pollution problems others argue that it is inefficient and unfair inefficient in the way most rationing devices are inefficient unfair because it is more easily avoided or accommodated by some than by others finally some people are arguing that the regulation is counterproductive actually increasing the levels of congestion and pollution because many households have purchased additional cars to circumvent the ban this article analyzes the policy pragmatically section i shows how the results of rationing can be compared with those that would be obtained using market

elasticities in aids models in the literature a variety of approaches have been used to calculate demand elasticities in almost ideal demand system aids models of demand it is common to estimate the linear approximate almost ideal demand system la aids instead of the aids when the la aids is estimated all of the previously reported approaches to compute elasticities are theoretically incorrect this paper presents correct formulas for la aids elasticities and illustrates the potential errors from using incorrect computing the almost ideal demand system aids of deaton and muellbauer 1980a b has become popular in recent years anderson and blundell blanciforti and green 1983a b blanciforti green and king chalfant eales and unnevehr fujii khaled and mak fulponi heien and willett murray parsons ray a variety of approaches to computing elasticities has been used and some of the approaches may lead to significant errors this paper clarifies the differences between alternative approaches to estimating demand elasticities in aids models

an empirical analysis of electricity consumption in cyprus abstract the paper presents the first empirical analysis of electricity consumption in cyprus using annual data from 1960 to 2004 we have examined electricity use in the residential and the services sectors which are the fastest growing electricity consumers in the island and its interaction with income prices and the weather the analysis was performed with the aid of time series analysis techniques such as unit root tests with and without a structural break in levels cointegration tests vector error correction models granger causality tests and impulse response functions results show long term elasticities of electricity use above unity for income and of the order of 0 3 to 0 4 for prices in the short term electricity consumption is rather inelastic mostly affected by weather fluctuations granger causality tests confirm exogeneity of electricity prices and bidirectional causality between residential electricity consumption and private income the commercial sector is less elastic and reverts faster to equilibrium than the residential sector despite the relatively small sample size results reported here are quite robust and can be used for forecasts and policy analyses

ethanol demand in brazil regional approach abstract successive studies attempting to clarify national aspects of ethanol demand have assisted policy makers and producers in defining strategies but little information is available on the dynamic of regional ethanol markets this study aims to analyze the characteristics of ethanol demand at the regional level taking into account the peculiarities of the developed center south and the developing north northeast regions regional ethanol demand is evaluated based on a set of market variables that include ethanol price consumer s income vehicle stock and prices of substitute fuels i e gasoline and natural gas a panel cointegration analysis with monthly observations from january 2003 to april 2010 is employed to estimate the long run demand elasticity the results reveal that the demand for ethanol in brazil differs between regions while in the center south region the price elasticity for both ethanol and alternative fuels is high consumption in the north northeast is more sensitive to changes in the stock of the ethanol powered fleet and income these among other evidences suggest that the pattern of ethanol demand in the center south region most closely resembles that in developed nations while the pattern of demand in the north northeast most closely resembles that in developing nations

corporate tax integration in the united states a general equilibrium approach this paper presents estimates of static and dynamic general equilibrium resource allocation effects for four alternative plans for corporate and personal income tax integration in the united states a medium scale numerical general equilibrium model is used which integrates the u s tax system with consumer demand behavior by household and producer behavior by industry results indicate that total integration of personal and corporate taxes would yield an annual static efficiency gain of around 6 billion 1973 dollars partial integration plans yield less dynamic effects are larger and our analysis indicates that full integration may yield gains whose present value is as large as 500 billion or about 1 0 percent of the discounted present value of the gnp stream to the u s economy after correction for population growth plans differ in their distributional impacts although these findings depend on the nature of replacement taxes used to preserve government revenues the size of dynamic resource allocation effects is sensitive to the choice of the replacement tax while static gains are reasonably robust

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
