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

information processing theory and the multinational enterprise this paper attempts to extend information processing theory so that it can be meaningfully applied to mncs a specific multidimensional framework is developed that can be used to measure the information processing capacities of macro level features of mnc organizational design an applied example transnationalism is used to illustrate how to apply the framework and demonstrate that it can contribute meaningful new insight to this complex organizational problem

efficiency and deregulation of the electricity market in singapore this study examines production efficiency of electricity generation in the new electricity market of singapore nems where deregulation is currently proceeding singapore is reliant on foreign direct investments and exports so competition from countries with lower costs such as china and india is exerting pressure on the government to reduce the costs of doing business here electricity cost is one of these deregulation is believed to be able to bring about lower electricity costs due to the various efficiency gains possible this study concerns itself mainly with production efficiency and attempts to calculate possible production efficiency gains by using linear programming model production efficiency gains are quantified by the base case scenario of continued regulation versus four counterfactual deregulation scenarios the results indicate that cost gains could be about eight per cent of current production cost and this is possibly a lower bound estimate however whether the purported efficiency gains are realized is to be seen as the deregulation proceeds

effectively conceiving and executing multinationals worldwide strategies this study addresses one of the most compelling questions in the field of international management how can a multinational simultaneously pursue the double ended objective of effectively conceiving and executing its worldwide strategy here we examine the ways in which the dynamics of the strategy making process between head office and subsidiary units influence the multinational s ability to achieve these two objectives specifically we introduce the concept of procedural justice the intellectual root of which is grounded in social psychology and law into the international management and explore the impact of process fairness on multinationals ability to conceive and execute effective worldwide strategies the results of this research are based on a two phase longitudinal study of the decision making dynamics of nineteen multinationals they provide support that the exercise of procedural justice is indeed a powerful way to organize the multinationals strategy making process procedural justice was found to significantly augment multinationals ability to achieve this double ended objective

decomposition analysis of the variations in residential electricity consumption in brazil for the 1980 2007 period measuring the activity intensity and structure effects abstract introduced at the end of the 1970s to study the impacts of structural changes on electricity consumption by industry index decomposition analysis techniques have been extended to various other areas to help in the formulation of energy policies notably in developed countries however few authors have applied these techniques to study the evolution of energy consumption in developing countries in brazil the few available studies have focused only on the industrial sector in this article we apply the decomposition technique called the logarithmic mean divisia index lmdi to electricity consumption of the brazilian residential sector to explain its evolution in terms of the activity structure and intensity affects over the period from 1980 to 2007 the technique is sufficiently robust and flexible to perform this analysis by disaggregating residential consumers by consumption classes and regions of the country among the main results is measurement of the impact of government programs for income transfer and universal service on variations in residential consumption typical of developing countries

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

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

accelerated electricity conservation in juneau alaska a study of household activities that reduced demand 25 abstract an avalanche destroyed the main hydroelectric transmission line to juneau alaska in april 2008 diesel generated electricity was substituted causing electricity prices to increase 500 for 45 days electricity demand fell by 25 during the supply disruption most of the reduction occurred before the higher rates were implemented some conservation about 8 of historic consumption persisted after the transmission line was repaired and prices returned to normal consumers reduced energy use through a combination of new habits and technical improvements a survey of residential consumers indicated that the average household undertook 10 conservation actions with major changes in lighting space heating fuel switching and water and appliance use we propose a method for prioritizing conservation actions for promotion according to their impact in electricity savings as a function of popularity effectiveness and persistence and a dynamic framework for electricity use before during and after a supply disruption i e both the magnitude and rates of change in electricity conservation

auctions and the price of art the value of most important works of art is established by public auction either directly by an actual sale or indirectly by reference to other sales how the auction system works is thus a critical determinant of how the public s preferences are translated into the evaluation of artistic work the auction system is central in the determination of the incentives for artistic work and the efficiency of the auction system is a key determinant of the cost of creating and distributing works of art this paper contains a review of the burgeoning new research of the last decade that has been designed to shed light on how the art auction system actually works what it indicates about price formation and how well it performs we begin our discussion in section 2 with a short description of the mechanics of the auction system and then organize the remainder of our discussion around two major topics the first topic concerns how auction prices can be used to determine and compare overall price movements within the art market and other markets and the second topic concerns how the auction mechanism influences prices we

are art auction estimates biased this article considers whether presale auction estimates are unbiased predictors of price when no sales are considered utilizing a newly constructed sample of over 500 works by eight early twentieth century american artists unbiased presale auction estimates in predicting price while expected are generally not supported in previous work but these studies excepting one do not include no sales in the calculations in order to study the question we employ a standard approach that uses an inverse mills ratio arising from a sample selection probit to correct for selection bias we find that controlling for selection bias presale auction estimates appear to be biased downward and we offer possible reasons for this result

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

vested interest and biased price estimates evidence from an auction market this study employs a new data set from art auctions to examine the relationship between auctioneer presale price estimates and the long term performance of artworks we find that the price estimates for expensive paintings have a consistent upward bias over a long period of 30 years high estimates at the time of purchase are associated with adverse subsequent abnormal returns moreover the estimation error for individual paintings tends to persist over time these results are consistent with the view that auction house price estimates are affected by agency problems and that

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

a comparison of canadian and japanese cognitive styles implications for management interaction many american and canadian companies seeking to form joint ventures and alliances with japanese companies or to negotiate contracts with them have discovered that the interaction can be difficult and frustrating value differences and preferences for different management practices have been identified that contribute to these interaction problems however little research has investigated potential differences in cognitive style that might also contribute to intercultural conflict this study compares samples of canadian and japanese mba students using the myers briggs type inventory mbti and links the findings to interaction difficulties reported in the literature

task attributes and process integration in business process offshoring a perspective of service providers from india and china this study addresses an important issue in designing and managing business process offshoring bpo process integration between an offshore service provider and its global bpo client we applied the information processing lens in global bpo and developed the logic that internationally disaggregated process integration requires a fit between process integration and bpo s task characteristics i e task complexity and security and task interdependence task connectivity stickiness and dependency this alignment is further moderated by the task context such as the geographic dispersion of the global client s end customers and the type of offshore provider independent vendor vs captive and joint venture finally we suggest that process integration has a positive but curvilinear relationship with the economic returns achieved by offshore providers our analysis of 308 bpo companies in india and china supports our propositions we conclude that international managers monitoring and integrating globally disaggregated activities in bpo should establish a proper alignment with the bpo project s task traits and task interdependence and look closely at the conditioning effect of external complexity by redressing the paucity of research on governing global bpo this study offers some insights into the integration externalization dynamics for growing business knowledge process offshoring

multi round procurement auctions with secret reserve prices theory and evidence when a secret reserve price is used in an auction the auctioneer cannot guarantee that the good can be sold out at the auction and can reauction the unsold objects in the next round motivated by this interesting feature observed in the procurement auctions organized by the indiana department of transportation we construct a dynamic bidding model in multi round procurement auctions with secret reserve prices and evaluate how the release of the auctioneer s reserve price affects bidders bidding behavior and the auctioneer s expected payment our theoretical model predicts that the equilibrium bids uniformly decline over stages and the numerical analysis of our model indicates that hiding the reserve price may be better than announcing it for the auctioneer under some specifications of underlying distributions we develop an empirical model with bidders discount factor equal to zero to recover the unknown structural parameters and to conduct counterfactual analyses copyright 2008 john wiley sons ltd

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

what we talk about when we talk about global mindset managerial cognition in multinational corporations recent developments in the global economy and in multinational corporations have placed significant emphasis on the cognitive orientations of managers giving rise to a number of concepts such as global mindset that are presumed to be associated with the effective management of multinational corporations this paper reviews the literature on global mindset and clarifies some of the conceptual confusion surrounding the construct we identify common themes across writers suggesting that the majority of studies fall into one of three research perspectives cultural strategic and multidimensional we also identify two constructs from the social sciences cosmopolitanism and cognitive complexity that underlie the perspectives found in the literature we then use these two constructs to develop an integrative theoretical framework of global mindset we then provide a critical assessment of the field of global mindset and suggest directions for future theoretical and empirical research

the impact of singapore s residential electricity conservation efforts and the way forward insights from the bounds testing approach abstract this article provides fresh empirical evidence of residential electricity demand in singapore over the period of 1980 2014 using the bounds testing procedure to cointegration the residential electricity demand comprises of income price temperature rainy days old age dependency and the impact of energy efficiency policies our results are consistent with previous studies where income and price elasticities are inelastic hence from a policy perspective subsidies will not be effective in reducing electricity demand we also found that old age dependency is an important determinant that reduces electricity consumption at least in the short run suggesting that policies that target the younger population may bring more savings the model findings suggest that in general energy efficiency interventions introduced after 2007 which comprises of both informational strategies and efficiency standards were effective in reducing household electricity consumption however in order to realise greater electricity reduction potential policy efforts have to intensify into the future with the main objectives being to permanently change energy habits and consider the role of hassle costs when rolling out energy saving measures

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

a random walk through mayfair art as a luxury good and evidence from dynamic models abstract the movement of international art prices in conjunction with other asset prices is preliminary to our understanding whether art is a luxury good it is well known that there are linkages between art market prices and equity prices however less is known about the structure of dependence between these variables and the influence of gold prices and sentiment we analyse art prices at the outset using granger causality and error correction models ecm to capture the long term dynamics between art prices equity markets gold prices and investor sentiment the dataset we use is unique and covers british art prices from 1895 to the present initial results do not give a complete picture of price movements or a fitting description of wealth effects to rectify this we look at short term dynamics in the art market we assume a regime switching model to describe the movement of prices using a threshold variable that drives prices into possibly locally explosive regimes these results indicate a dynamic wealth effect in that high low stock prices lead to subsequent increases decreases in art prices however this approach means that elasticities are now stochastic and we redefine what a luxury good is this is further explored by directly calculating elasticities from our model and its variants to analyse properties of art as a luxury good our threshold approach gives deeper insight into the impact of different market conditions than conventional ecm and cointegration modelling

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

trends in prices to commercial energy consumers in the competitive texas electricity market abstract to date the price of electricity to commercial or business energy consumers has generally increased at greater rates in the areas of texas where retail competition has been introduced than in areas that do not enjoy competition trends in commercial competitive prices have largely mirrored trends in residential prices market restructuring has tended to increase the sensitivity of retail electricity prices to changes in the price of natural gas the marginal fuel used for generation in texas consequently the rapid increases in the commodity price of natural gas following restructuring led to increases in competitive electric rates which exceeded the increases in areas not exposed to restructuring where the fuel component of electric rates tend to reflect a weighted average of the utilities fuel costs there is some evidence that pricing behavior by competitive retailers changed when the retailers affiliated with the incumbent utilities were permitted some pricing flexibility resulting in a reduction in prices

structural changes in residential energy demand abstract residential energy consumers in the usa faced several demand shocks in the 1970s and 1980s these included price rises engineered by the organization of petroleum exporting countries natural gas curtailments shortages of petroleum products and deregulation of energy markets one result of these events has been structural change in the demand for electricity and petroleum by residential consumers demand functions are now more responsive to price changes and consumers react more quickly in adjusting their capital stocks to new levels

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

art as an investment the market for modern prints repeat sales of modern prints at auction are used to estimate a semiannual index of prices for the period 1977 92 as in other studies of art as an investment prints do not compare favorably to traditional financial assets there is substantial noise in auction prices but little or no support for the proposition that some artists command higher prices in certain countries or that masterpieces outperform the market one puzzle is the continuing tendency for prices realized at certain auction houses to exceed those realized at others notably at sotheby s relative to christie s in new york copyright 1993 by american economic association

us consumers willingness to pay for green electricity abstract we analyze us consumers demand for environmental attributes of deregulated residential electricity services using results from a survey designed to elicit consumers willingness to pay for such attributes and using results from a hedonic analysis of actual price premiums charged for green electricity in several deregulated markets survey results suggest that many population segments are willing to pay for decreased air emissions even if there is no alteration in fuel source furthermore several groups are willing to pay significantly more when emissions reductions stem from increased reliance upon renewable fuels the hedonic analysis suggests that several product features not considered in the survey help explain real price premiums including fuel mix from newly created renewable generation capacity green e certification brand name and state of offer while survey and hedonic results are not easily compared due to limitations of the survey both point to similar values for key environmental attributes though the survey results are likely to overstate actual willingness to pay in sum the results suggest that consumer driven purchases can in part support the future of renewable generation capacity in the united states though reliance upon other policy alternatives may be needed if energy prices spike

productivity growth and deregulation of japanese electricity distribution deregulation of japanese electric power industry began in 1995 after the amendment of electricity utility industry law in 1995 competition was partially introduced in a generation sector and retail competition started from 2000 eligibility to choose suppliers was gradually extended from larger to smaller customers as of 2008 almost all customers except households can choose their electricity suppliers based upon both previous implementation result of competition policy and review on their achievement japanese government will begin new policy debate in 2013 to assess further retail competition which includes household customers to prepare for policy suggestion on the future electric power industry this study examines the cost structure of japanese electricity distribution for the purpose we estimate a multi product translog cost function of japanese electricity distribution from 1983 to 2003 using the estimated cost function we calculate several economic measures such as productivity growth technical change and economies of scale and scope the empirical results of this study indicate the improvement in productivity growth after deregulation

price elasticities of residential electricity demand estimates from household panel data in bangladesh abstract we collect a household level panel dataset to estimate the price elasticities of electricity demand for different types of urban households in bangladesh we use an instrumental variable estimation strategy which exploits exogenous variation in average electricity prices induced by a value added tax shock the results indicate significant heterogeneity in price elasticities by electricity consumption levels we conduct a number of simulations under alternative policy scenarios to illustrate how incorporating the heterogeneous nature of price elasticities into pricing policy can help decrease electricity demand supply mismatch and inequality in electricity consumption the results have important policy implications for developing countries aiming to address major energy issues by implementing tariff reforms

household consumption of electricity in brazil between 1985 and 2013 abstract this article describes the electricity consumption in brazilian residences between 1985 and 2013 through linear regressions the explanatory variables considered were the number of households effective consumption of families as a proxy for family income and electricity tariff for households to deal with the power generation crisis of 2001 we have introduced a dummy variable in the form of a step function with such explanatory variables we were able to account for the reduction of household electricity consumption caused by the policies conducted in 2001 and their permanent consequences the regression presented coefficient of determination of 0 9892 and the several statistic tests conducted assured the existence of long term relation between the electricity consumption in residences and the explanatory variables the obtained elasticities for the household consumption of electricity with respect to number of residences family income and residential tariff of electricity were 1 534 0 095 0 189 0 049 and 0 230 0 060 respectively these results allowed understanding the evolution over time of the household consumption of electricity in brazil they suggest that the electric sector in brazil should pursue an active policy to manage demand of residential electricity using tariffs as a means to control it

market seeking mnes in an emerging market how parent subsidiary links shape overseas success this study extends research on parent subsidiary links applying new theoretical perspectives those of resource dependence and dynamic capability to the new empirical setting of an emerging market we suggest that parent subsidiary links help to mitigate emerging market threats by reducing external dependence and help to capitalize on emerging market opportunities by enhancing local responsiveness

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

industrial electricity demand for turkey a structural time series analysis abstract this research investigates the relationship between turkish industrial electricity consumption industrial value added and electricity prices in order to forecast future turkish industrial electricity demand to achieve this an industrial electricity demand function for turkey is estimated by applying the structural time series technique to annual data over the period 1960 to 2008 in addition to identifying the size and significance of the price and industrial value added output elasticities this technique also uncovers the electricity underlying energy demand trend uedt for the turkish industrial sector and is as far as is known the first attempt to do this the results suggest that output and real electricity prices and a uedt all have an important role to play in driving turkish industrial electricity demand consequently they should all be incorporated when modelling turkish industrial electricity demand and the estimated uedt should arguably be considered in future energy policy decisions concerning the turkish electricity industry the output and price elasticities are estimated to be 0 15 and 0 16 respectively with an increasing but at a decreasing rate uedt and based on the estimated equation and different forecast assumptions it is predicted that turkish industrial electricity demand will be somewhere between 97 and 148 twh by 2020

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

estimation of japanese price elasticities of residential electricity demand 1990 2007 abstract this paper estimates elasticities of japanese residential price electricity from 1990 to 2007 the first difference generalized method of moment estimator is employed to avoid dynamic panel bias which is not considered in most previous studies the results show that while short run elasticities are similar to those in previous studies long run elasticities are significantly lower in our study we also find that the price elasticity of japanese residential electricity consumption is notably affected by income inequality and severe weather based on these results we provide some insights to tailor environmental taxation so as to effectively attain the kyoto protocol

residential energy demand in oecd countries and the role of irreversible efficiency improvements abstract after undergoing substantial changes during a period of high energy prices household energy demand did not rebound in times of declining energy prices as might have been expected hence other factors such as irreversible improvements in technical efficiency must be understood in order to describe both past and future household energy demand in this paper we consider irreversible efficiency improvements as a major reason for the moderate growth in energy demand after the plummeting of the oil price in 1985 we test different econometric models to take into account efficiency indicators the major conclusions of our investigation are i price elasticities are different for rising and falling prices for the latter they are close to zero implying a low rebound effect in the residential sector ii technical efficiency is an important parameter for describing and forecasting energy demand and iii income elasticities turn out to be higher once we incorporate indicators of technological efficiency in the process of estimating energy demand

structural changes in residential electricity demand abstract the purposes of this study are to investigate the structural changes in residential electricity demand parameters and explain the causes for such changes a dynamic model is specified and estimated using pooled time series and cross section state level data for the usa changes in demand parameters over time are examined by using successive over lapping ten year sample periods for data from 1955 78 for parameter estimation the results show that there have been significant structural changes in demand elasticities for several independent variables these changes can be best explained by changes in household stocks of major electric appliances as new technologies have been developed improved and ingrained in consumer lifestyles and preference functions over time further inquiry shows no strong evidence of structural changes associated with either the reversal of the declining trend of electricity prices or the 1973 oil embargo however more data after the oil embargo may be needed to validate the existence of price asymmetries in electricity demand

does market based electricity price affect china s energy efficiency abstract china is in a critical period of market oriented reform and energy transition as a crucial means to regulate supply and demand under the market oriented mechanism the electricity price can promote the development of energy efficiency by optimizing resource allocation with the gradual increase in electricity consumption the influence of its price on energy consumption is also gradually enhanced therefore this paper evaluated the process of electricity price marketization and conducted a spatial temporal comparative analysis of the effect of electricity price on energy efficiency by controlling economic policy and other price factors the results show that 1 the marketization degree of china s electricity price has improved with steady steps 2 market oriented electricity price has a stable positive correlation with energy efficiency in both the short and long term 3 marketization improves the promotion effect of electricity price on energy efficiency and the influence of electricity price is more significant in the eastern region with a high degree of marketization and the subsequent stage 4 the impact of market oriented electricity price on energy efficiency is asymmetric the impulse response under positive and negative shock is opposite and under the positive shock the response time is longer and the degree is greater

technical efficiency and impacts of deregulation an analysis of three functions in u s electric power utilities during the period from 1992 through 2000 the main purpose of this study is to examine the impacts of deregulation on technical efficiency and its changes over time for large scale u s electric power utilities during the period from 1992 through 2000 we analyze the efficiency of three individual functions i e generation transmission distribution and general administration and the deregulatory impacts on each of them in order to implement the analysis we estimate an input distance function by using a stochastic frontier analysis the results indicate that there is a significant impact of deregulation on efficiency in the generation and general administration functions while no effects are observed in the transmission distribution function

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

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

sale rates and price movements in art auctions this paper examines the relationship between sale rates and price shocks in art auctions using data on contemporary and impressionist art we show that while sale rates appear to have little relationship to current prices there exists a strong negative relationship of sale rates to unexpected price shocks which is reminiscent of a phillips curve we estimate an empirical model that suggests that the reserve price is set on average at about 70 of the low estimate

how auctions work for wine and art interview auctioneers and even to buy a little wine in the meantime i have also had the opportunity with john abowd 1988 to observe and collect data on the auction sale of impressionist and contemporary paintings this paper reports on some of the empirical regularities that i and others have observed in the actual operation of the auction markets for these items in view of the rich and diverse array of theoretical literature on auctions it seems high time economists began to spell out precisely what facts it is meant to explain 2

dynamic capabilities and internationalization of authentic firms role of heritage assets administrative heritage and signature processes we study mnes that tie their long lasting competitiveness and internationalization to the deployment of their heritage assets administrative heritage and signature processes built in their home markets when faced with changes these authentic firms scan for and buffer against threats to their signature processes use their heritage endowment to focus on their capacity to maintain and defend their niches and preserve their capacity for stability we complement the traditional dynamic capabilities perspective by redefining its boundary conditions furthermore authentic firms resist and limit local adaptation of process and products and internationalize only if opportune by deploying preservation capabilities

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

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

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

auctioning and bargaining an econometric study of timber auctions with secret reservation prices this article considers a first price sealed bid auction at which the seller s reservation price is not announced in advance we allow for a second round of bargaining and consider the nash bargaining outcome when the object is unsold after the auctioning round we characterize the bidders and seller s bayesian nash equilibrium strategies the distributions of the buyers and seller s private values are estimated by nonlinear least squares from auction data on standing timber while solving numerically the differential equations characterizing the seller s and buyers equilibrium strategies the performance of the estimated model is then compared to a model in which the players behave myopically

sensitivity of price elasticity of demand to aggregation unobserved heterogeneity price trends and price endogeneity evidence from u s data abstract price elasticity estimates of residential electricity demand vary widely across the energy economics and policy literature in this paper we seek to explain these findings using three nationwide datasets from the u s the american housing survey forms eia 861 and the residential energy consumption survey we examine the role of the sample period level of aggregation use of panel data use of instrumental variables and inclusion of housing characteristics and capital stock our findings suggest that price elasticities have remained relatively constant over time upon splitting our panel datasets into annual cross sections we do observe a negative relationship between price elasticities and the average price whether prices are rising or falling appears to have little effect on our estimates we also find that aggregating our data can result in both higher and lower price elasticity estimates depending on the dataset used and that controlling for unit level fixed effects with panel data generally results in more inelastic demand functions addressing the endogeneity of price and or measurement error in price with instrumental variables has a small but noticeable effect on the price elasticities finally controlling for housing characteristics and capital stock produces a lower price elasticity

a meta analysis on the price elasticity and income elasticity of residential electricity demand abstract price elasticity and income elasticity can quantitatively measure the impact of price volatility and income diversity on household electricity demand to analyze household electricity demand and better identify the main factors affecting residential electricity demand elasticity in previous literature a meta analysis based on a comprehensive and systematic summary of 103 articles is presented in this study the influencing factors are identified with a weighed least squares wls linear regression model to evaluate their strength the price elasticities and income elasticities are discussed from three dimensions namely short term long term and unmarked the results show that residential electricity demand is almost price inelastic and income inelastic in the short term but in the long term some residential electricity demand is price elastic and income elastic the results also reveal that residential electricity demand elasticity is affected by many factors such as time interval and sample period these conclusions can support the formulation of more effective electricity price and energy policy

restructuring electricity policy and financial models the old regulated electric industry provided reliable service not necessarily in the most economic manner at a declining real price the semi competitive electric industry model now operating in the united states and the uk has shown that electric companies can operate more efficiently than before but it has not delivered significantly greater benefits to consumers than the old model financial modelers and policy makers should address those issues whose solution will provide the most bang for the buck in order to bring about greater benefits to consumers

residential electricity consumption in portugal findings from top down and bottom up models an econometric study of the portuguese residential electricity consumption is presented with a focus on the influence of dwelling characteristics on consumption the relationship between the dwelling and household characteristics on per capita residential electricity consumption is estimated at two different scales involving two distinct databases the first includes data at the municipality level for 2001 the second is the most recent portuguese consumer expenditure survey that was collected in 2005 and 2006 the results of the analysis at both scales are consistent and indicate that household and dwelling characteristics have a significant influence on residential electricity consumption our results show that in portugal the direct effect of income on electricity consumption is low and becomes smaller when more relevant control variables are included in the analysis future demand of electricity in portugal will be significantly influenced by trends in socioeconomic factors as well as changes in the building stock these trends should be taken in consideration in the formulation of policy measures to reduce electricity consumption

the structure of electricity demand in the brazilian household sector abstract the present structure of residential electricity demand is analysed by electricity consumption classes and end uses nearly 70 of households consume less than 150 kwh month and are responsible for 35 of total residential demand other determinants of electricity use such as income and place of residence are also discussed it is found that electricity demand is increasing faster than income as the country reaches appliances saturation in upper consumption levels water heating and refrigeration account for the major part of residential consumption residential conservation efforts have started introducing more efficient lighting equipment and refrigerators but further work will have to be done to speed up the diffusion of efficient technology at costs that can be paid by consumers

estimating residential demand for electricity in the united states 1965 2006 abstract this paper examines the residential demand for electricity in the us economy as a function of the per capita income the price of electricity the price of oil for heating purposes the weather conditions and the stock of occupied housing over the period 1965 2006 this paper has two novelties first the occupied stock of houses as a proxy for the stock of electrical appliances and second the identification of a possible equilibrium relationship among the variables is ascertained through the recently advanced ardl approach to cointegration our empirical findings give support to a stable long run relationship implying also short run and long run elasticities whose size and sign are comparable to other similar studies

retail competition in electricity supply survey results in north carolina residential retail competition in electricity supply was introduced in many countries and some us states as part of electricity industry deregulation following problems in the electricity market in california in 2000 2001 many us states including north carolina suspended their deregulation agenda recent technological advances have made competition more viable so we ask if nc should reconsider deregulation and retail competition the welfare benefits will depend on consumers willingness to switch suppliers and the potential for value added innovations in electricity and industries such as pay tv and telecommunications consumers are sticky remaining with their current supplier even though rivals offer savings moreover some analysts question the likelihood of significant welfare improvements from retail competition we survey residents in two nc counties focusing on i households knowledge of and interest in retail competition ii factors that would encourage them to switch suppliers and iii the required savings to encourage switching about 50 65 of respondents would favor retail competition in nc demographic variables and experience switching in other industries affect opinions and the savings required to incent switching we conclude the estimated rate reduction to encourage competitive switching will be hard to achieve in nc as long as rates remain below the national average

industrial and residential electricity demand dynamics in japan how did price and income elasticities evolve from 1989 to 2014 abstract this study estimates the price and income elasticities of industrial and residential electricity demand in japan with the annual data from 1989 to 2014 a time varying parameter tvp model with the kalman filter is applied to monitor the evolution of consumer behaviors in the post bubble period given the exogenous shock financial crisis in 2008 and the structural breaks electricity deregulation and fukushima daiichi crisis the tvp model can provide a robust estimation of elasticities and can detect the outliers and the structural breaks the results suggest that both industrial and residential consumers become less sensitive to price after the electricity deregulation and the financial crisis and more sensitive to price after the fukushima daiichi crisis especially the industrial sector is less sensitive to price after the retail deregulation by contrast the income elasticities of industrial and residential sector consumers are stable during the examined period results also indicate that a negative relationship exists between the price elasticity of electricity demand and the price level of electricity after the electric sector deregulation some insights on the further electric sector reform and the environmental taxation in japan are also provided

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

declining values and the afternoon effect evidence from art auctions we study the order of sale in art auctions the final bid relative to the auctioneer s estimated price declines throughout the course of an auction a theoretical model shows that in an auction ordered by declining valuation even in the presence of risk neutral strategic bidders the price received relative to the estimate for later items in an auction should be less than the price relative to the estimate for earlier items furthermore ordering heterogeneous items by value maximizes revenue for the auctioneer

electricity liberalisation in europe how competitive will it be all the countries of western europe have taken steps to liberalise their electricity industries large consumers in every country can choose their electricity supplier and in some countries this choice has been extended to every consumer the european union has decided that from 2007 at the latest all customers will be able to choose their electricity supplier a number of large european electricity companies have been responding to this changing environment by merging with electricity companies in other countries this means that while some national markets may not look unduly concentrated concentration at the european level has been growing this paper addresses the reasons for this and asks whether the resulting industry structure will be sufficiently competitive to deliver gains from liberalisation

seasonality in dynamic regression models this paper examines the implications of treating seasonality as an unobserved component which changes slowly over time this approach simplifies the specification of dynamic relationships by separating non seasonal from seasonal factors we illustrate this approach using the consumption model of davidson et al 1978 and estimate a stable error correction model between consumption income and prices over the period 1958 92 more generally we argue that autoregressive models are unlikely to successfully model slowly changing seasonality and may confound seasonal effects with the dynamic responses of prime interest our approach can be used in a wide range of cases and we show that there is little loss in efficiency even if seasonality is deterministic

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

the evolution of price elasticity of electricity demand in south africa a kalman filter application abstract in south africa the electricity mismatch of supply and demand has been of major concern additional to past problems the 2008 electricity crisis made the solution crucial after its damaging consequences to the economy the disagreement on the need and consequences of the continuous electricity price hikes worsens the situation to contribute to the recent electricity debate this paper proposes a time varying price elasticity of demand for electricity the sensitivity of electricity consumption to price fluctuations changes throughout the years the main purpose of this study is the estimation of the price elasticity of electricity in south africa during the period 1980 2005 by employing an advanced econometric technique the kalman filter apart from the decreasing effect of electricity prices to consumption 71 8 in the 1990s and 94 5 in the 2000s in average our results conclude to an important finding the higher the prices for example in the 1980s the higher the sensitivity of consumers to price fluctuations thus further increases of the electricity prices may lead to changes in the behaviour of electricity consumers focusing their efforts on improving their efficiency levels by introducing demand side management techniques or even turning to other sources of cheaper energy

estimating house price indexes in the presence of seller reservation prices we analyze a bias in transaction based price indexes due to the presence of seller reservation prices we develop a model in which the ratio of sellers reservation prices to the market value affects trading volume and biases of observed transaction prices when trading volume decreases increases index returns are estimated with an upward downward bias we propose a new econometric procedure to mitigate the bias and use simulations to demonstrate the effectiveness of the procedure we construct a reserve conditional unbiased index for the los angeles housing market which substantially differs from a traditional repeat sale index

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

the effects of sfas 131 geographic segment disclosures by us multinational companies on the valuation of foreign earnings foreign operations are becoming increasingly important for us companies we investigate whether the market s valuation of foreign earnings is a function of the firm s geographic segment disclosures specifically we examine the effects of an increase in the number of geographic segments disclosed and the inclusion of earnings measures in geographic segment disclosures following the adoption of sfas 131 we find strong evidence that our proxies for increased disclosure are positively associated with the valuation of foreign earnings our results are robust to a number of sensitivity analyses taken together our results suggest that the pricing of foreign earnings is associated with important aspects of the firm s information environment

global account management in multinational corporations theory and evidence this paper uses two theoretical perspectives information processing and resource dependency to examine global account management the co ordination of activities involved in serving a single customer in multiple countries it is hypothesized that global account management structures allow the multinational corporation mnc to increase its information processing capacity as well as its bargaining power vis a vis the global customer using data on 106 global accounts in 16 mncs we find support for both perspectives individually furthermore evidence is presented for an interaction effect in which the effectiveness of structures for increasing information processing is conditional upon the presence of high customer dependence

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

modelling and forecasting turkish residential electricity demand abstract this research investigates the relationship between turkish residential electricity consumption household total final consumption expenditure and residential electricity prices by applying the structural time series model to annual data over the period from 1960 to 2008 household total final consumption expenditure real energy prices and an underlying energy demand trend are found to be important drivers of turkish residential electricity demand with the estimated short run and the long run total final consumption expenditure elasticities being 0 38 and 1 57 respectively and the estimated short run and long run price elasticities being 0 09 and 0 38 respectively moreover the estimated underlying energy demand trend which as far as is known has not been investigated before for the turkish residential sector should be of some benefit to turkish decision makers in terms of energy planning it provides information about the impact of past policies the influence of technical progress the impacts of changes in consumer behaviour and the effects of changes in economic structure furthermore based on the estimated equation and different forecast assumptions it is predicted that turkish residential electricity demand will be somewhere between 48 and 80 twh by 2020 compared to 40 twh in 2008

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

a decision support tool for the analysis of pricing investment and regulatory processes in a decentralized electricity market abstract after the liberalization of the electricity generation industry capacity expansion decisions are made by multiple self oriented power companies unlike the centralized environment decision making of market participants is now guided by price signal feedbacks and by an imperfect foresight of the future market conditions and competitor actions that they will face in such an environment decision makers need to better understand long term dynamics of the supply and demand sides of the power market in this study a system dynamics model is developed to better understand and analyze the decentralized and competitive electricity market dynamics in the long run the developed simulation model oversees a 20 year planning horizon it includes a demand module a capacity expansion module a power generation module an accounting and finance module various competitors a regulatory body and a bidding mechanism many features singularities and tools of decentralized markets such as capacity withholding enforced divestment long term contracts price elastic demands incentives disincentives are also incorporated into the model public regulators and power companies are potential users of the model for learning and decision support in policy design and strategic planning results of scenario analysis are presented to illustrate potential use of the model

the impact of reserve prices on the perceived bias of expert appraisals of fine art we examine whether the expert appraisals provided to bidders before major art auctions are unbiased indicators of market value despite a strong grounding in theory this aspect of optimal auction design has been frequently challenged in previous empirical research particularly in the market for fine art we adopt a valuation benchmark that incorporates sellers reservation prices as well as high bids and recognize latent censoring due to works that fail to make reserve although the auction houses never divulge sellers reserve prices which are therefore unobservable we exploit the fact that they can be observed indirectly via their impact on buy in rates using the set of french impressionist paintings brought to auction from 1985 to 2001 we estimate the distribution of seller reserve prices establish their link to a proper valuation benchmark and isolate the selection bias due to bought in works on the perceived market value of fine art works brought to auction after controlling for the impact of reservation prices and considering all works brought to auction and therefore all works appraised we find no evidence of bias in the experts pre sale estimates
