crisis or opportunity economic degrowth for social equity and ecological sustainability introduction to this special issue abstract this article reviews the burgeoning emerging literature on sustainable degrowth this is defined as an equitable downscaling of production and consumption that increases human well being and enhances ecological conditions at the local and global level in the short and long term the paradigmatic propositions of degrowth are that economic growth is not sustainable and that human progress without economic growth is possible degrowth proponents come from diverse origins some are critics of market globalization new technologies or the imposition of western models of development in the rest of the world all criticize gdp accounting though they propose often different social and ecological indicators degrowth theorists and practitioners support an extension of human relations instead of market relations demand a deepening of democracy defend ecosystems and propose a more equal distribution of wealth we distinguish between depression i e unplanned degrowth within a growth regime and sustainable degrowth a voluntary smooth and equitable transition to a regime of lower production and consumption the question we ask is how positive would degrowth be if instead of being imposed by an economic crisis it would actually be a democratic collective decision a project with the ambition of getting closer to ecological sustainability and socio environmental justice worldwide most articles in this issue were originally presented at the april 2008 conference in paris on economic degrowth for ecological sustainability and social equity this conference brought the word degrowth and the concepts around it into an international academic setting articles of this special issue are summarized in this introductory article hueting d alessandro and colleagues van den bergh kerschner spangenberg and alcott discuss whether current growth patterns are un sustainable and offer different perspectives on what degrowth might mean and whether and under what conditions it might be desirable matthey and hamilton focus on social dynamics and the obstacles and opportunities for voluntary social action towards degrowth lietaert and cattaneo with gavalda offer a down to earth empirical discussion of two practical living experiments cohousing and squats highlighting the obstacles for scaling up such alternatives finally van griethuysen explains why growth is an imperative in modern market economies raising also the question whether degrowth is possible without radical institutional changes

knowledge spillovers and patent citations evidence from a survey of inventors it is well understood that the non rival nature of knowledge as a productive asset creates the possibility of knowledge spillovers whereby investments in knowledge creation by one party produce external benefits by facilitating innovation by other parties at least since zvi griliches s 1979 seminal paper on measuring the contributions of r d to economic growth economists have been attempting to quantify the extent and impact of knowledge spillovers one line of research of this type has utilized patent citations to identify a paper trail that may be associated with knowledge flows between firms very little of this research has attempted to determine the modes or mechanisms of communication that actually permit knowledge to flow further most of the work has simply assumed that citations or other proxies are sufficiently correlated with knowledge flows to allow statistical analysis of the proxies to be informative regarding the underlying phenomenon of interest this paper reports on a preliminary attempt to improve this situation the idea for this survey came from r d managers whom we were interviewing to test whether the picture of knowledge flows produced by patent citations was consistent with the managers impressions one of these managers commented that he could not let us talk to the scientists who worked for him but that he could not stop uls from contacting them via the postal address that appears on their issued patents the survey results suggest that communication between inventors is reasonably irnportant and that patent citations do provide an indication of communication albeit one that also carries a fair amount of noise

the carbon footprint of uk households 1990 2004 a socio economically disaggregated quasi multi regional input output model this paper presents a socio economically disaggregated framework for attributing co2 emissions to people s high level functional needs based around a quasi multi regional input output qmrio model the study in theory takes into account all co2 emissions that arise from energy used in production of goods and services to satisfy uk household demand whether the emissions occur in the uk or abroad results show that co2 emissions attributable to households were 15 above 1990 levels in 2004 and that although absolute decoupling occurred between household expenditure and co2 during the uk s switch from coal to gas in the early 1990s since then only slight relative decoupling is evident the proportion of co2 that arises outside uk borders in support of uk consumption is rising and reducing these emissions is particularly problematic in a global trading system investigation into the carbon footprint of different segments of the uk population shows wide variation the segment with the highest carbon footprint emits 64 more co2 than the segment with the lowest results show that recreation and leisure are responsible for over one quarter of co2 emissions in a typical uk household in 2004 we conclude that expanding lifestyle aspirations are significant factors in driving household co2 emissions but the study also emphasizes that attention must be paid to the infrastructures and institutions that result in considerable amounts of co2 being locked up in basic household activities through which people meet their everyday needs for subsistence protection and communication with family and friends the findings highlight the sheer scale of the challenge facing uk policy makers and suggest that policies should be targeted towards segments of society responsible for the highest carbon footprints

relating the environmental impact of consumption to household expenditures an input output analysis in this paper we evaluate the relationships between household expenditures and the environmental impact categories climate change acidification eutrophication and smog formation by combining household expenditures with environmentally extended input output analysis expenditure elasticities are examined with regression analysis and are compared and interpreted on the basis of insight at the product level with data from the netherlands in the year 2000 we find that environmental impact increases with increasing household expenditures although the degree to which the environmental impact increases differs per impact category climate change and eutrophication increase less than proportionally with increasing expenditures acidification increases nearly proportionally with increasing expenditures whereas smog formation increases more than proportionally it appears that the mix of necessities and luxuries to which an environmental impact is related is essential in explaining the relationship

behavioural attitudes towards water saving evidence from a study of environmental actions given the growing emphasis being placed on water conservation in and around the home by water companies there is a pressing need to identify the characteristics of the water saver so that policy makers can more accurately target initiatives for water conservation this paper examines the social attitudinal and behavioural composition of water saving activities using a sample of 1600 households from devon the research sought to examine the links between water saving energy conservation green consumerism and waste management in and around the home accordingly the extent to which water saving can be placed within a behavioural context that incorporates different environmental behaviours is discussed the data relating to water saving are then analysed and four different types of individual are defined according to their behavioural characteristics these are examined in the context of their demographic composition and a range of attitudinal factors the policy implications of the research are described throughout the paper

targeting energy justice exploring spatial racial ethnic and socioeconomic disparities in urban residential heating energy efficiency abstract fuel poverty the inability of households to afford adequate energy services such as heating is a major energy justice concern increasing residential energy efficiency is a strategic fuel poverty intervention however the absence of easily accessible household energy data impedes effective targeting of energy efficiency programs this paper uses publicly available data bottom up modeling and small area estimation techniques to predict the mean census block group residential heating energy use intensity eui an energy efficiency proxy in kansas city missouri results mapped using geographic information systems gis and statistical analysis show disparities in the relationship between heating eui and spatial racial ethnic and socioeconomic block group characteristics block groups with lower median incomes a greater percentage of households below poverty a greater percentage of racial ethnic minority headed households and a larger percentage of adults with less than a high school education were on average less energy efficient higher euis results also imply that racial segregation which continues to influence urban housing choices exposes black and hispanic households to increased fuel poverty vulnerability lastly the spatial concentration and demographics of vulnerable block groups suggest proactive area and community based targeting of energy efficiency assistance programs may be more effective than existing self referral approaches

technology as a complex adaptive system evidence from patent data this paper develops a theory of invention by drawing on complex adaptive systems theory we see invention as a process of recombinant search over technology landscapes this framing suggests that inventors might face a complexity catastrophe when they attempt to combine highly interdependent technologies our empirical analysis of patent citation rates supports this expectation our results also suggest however that the process of invention differs in important ways from biological evolution we discuss the implications of these findings for research on technological evolution industrial change and technology strategy 2001 elsevier science b v all rights reserved

energy consumption and urban sprawl evidence for the spanish case residential electricity consumption constitutes one of the largest sources of spanish final energy demand to improve electricity savings policies oriented towards efficiency in residential consumption such as replacement of appliances or the construction of nearly zero energy buildings have been suggested and implemented however the potential relevance of urban structural characteristics such as the increase in detached houses in sprawling residential areas has not often been considered the aim of this research is to analyse the relevance of living in a detached house located in a dispersed urban area to household electricity consumption thus an electricity consumption model is estimated by using household socioeconomic variables and including urban characteristics as its determinants such us the level of urban agglomeration or whether families live in detached sprawling homes the model is estimated by using 2014 household budget survey hbs microdata and applying ordinary least squares ols as well as quantile regressions qr as econometric procedures endogeneity problems are corrected by means of instrumental variables the results confirm that living in a detached house significantly increases electricity consumption whereas urban agglomerations have the opposite effect sprawl is occurring rapidly in spanish cities and according to our results it could constitute a relevant source of increase in electricity demand in the following years

fossil resource trade balances emerging trends for the uk abstract the aim of this paper is to examine the extent to which the uk can be classified as a net importer of fossil resources and a creator of pollution havens abroad between 1968 and 2000 using input output techniques and a derived resource flow classification system both the physical trade balance ptb and pollution trade balance utb associated with fossil resource use are computed the ptb shows that between 1968 and the early 1980 s the uk is presented as a net importer of direct fossil resource flows between 1984 and 2000 the uk is identified as a net exporter of direct fossil resources these trends are primarily explained by the uk s discovery and commercial production of north sea oil and gas fields in the late 1970s on the other hand the utb shows that over the whole period the indirect used flows attributable to the uk s exports are higher than those attributable to its imports these findings suggest that the uk did not create pollution havens abroad from the use of fossil resources between 1968 and 2000 however it is noticeable in both cases that from 1995 the uk s position as a net exporter has been decreasing considerably maturing north sea oil and gas fields set against increasing demands for fossil fuels and imported goods is signalling a return to the uk s pre 1984 dependence on direct imported fossil resources and the possible creation of pollution havens abroad knowledge of these trends contributes to the evidence base for the uk s changing import and export structure and the potential environmental repercussions at home and abroad

untangling the complexity of the direct and indirect determinants of the residential energy consumption in france quantitative analysis using a structural equation modeling approach abstract about a quarter of french energy demand is for residential use this study mobilises a multidisciplinary approach and a non linear modeling strategy to examine the total direct and indirect effects of households and housing units in designing french energy consumption based on micro level data from the new french 2012 phebus survey this research implements a structural equation model to tease out the effects of both dwelling characteristics household attributes climate and behaviours on the domestic energy use findings confirm that the direct effect of household related attributes on domestic energy demand is notably lower than the corresponding effect from the dwelling attributes nevertheless considering for the indirect effect of household factors on energy use across housing choices the total impact of household related attributes on the french domestic energy consumption is just slightly lower than that of dwelling characteristics therefore to highlight the spectrum of residential energy use this research calls to incorporate both direct and indirect effects of household attributes and choices this study suggests several key insights on how to incorporate housing policy into residential energy policy and reduce energy related greenhouse gas emissions

from frugal jane to wasteful john a quantile regression analysis of swiss households electricity demand abstract in this article we investigate the heterogeneity in the responsiveness of swiss household electricity demand to changes in prices and income we focus on segments of consumers with different intensities of electricity consumption by using a panel quantile regression approach this estimation strategy is applied to a rich micro level longitudinal data set of 3880 observations from more than 1400 households matched with a unique price data set extracted from the swiss electricity regulator s online sources while the findings show an inelastic electricity demand across all groups an interesting pattern of variation emerges between lower and upper quantiles of electricity demand respectively frugal and intensive users results show that households in the first conditional quartile and at the median react significantly to changes in prices while those at the lowest quantile and upper quantiles exhibit insignificant price elasticities the main policy implications of this work concern the design of price based measures for reducing electricity consumption in the residential sector and the possibility of accounting for individual responses in tailoring policies for specific consumer segments

modelling household energy expenditures using micro data this paper is concerned with the empirical modeling of domestic demand for energy in the united kingdom at the level of the individual household a two stage budgeting model of household demand for energy conditional on durable ownership is developed at the first stage income is allocated between energy and nonenergy consumption while at the second stage energy expenditure is disaggregated the second stage allocation is assumed to be between gas electricity and a composite good other fuels estimation takes place using a sample of some 50 000 households drawn from the annual u k family expenditure survey for the years 1972 83 a source that has not been fully exploited in the analysis of energy demand to date copyright 1989 by royal economic society

measuring consumption in households interpretations and strategies the paper discusses the connection between environmental awareness and metering data on household consumption electricity heating water and it is based on recent danish studies it is discussed how families understanding of environmental awareness and environmental practices relates to their overall household consumption the paper indicates that residents environmental practices in everyday life are often overshadowed by consumption practices in other areas and that such practices are often rooted in quite different rationales than environmental awareness these findings are seen as an example of what pierre bourdieu calls the economy of symbolic goods bourdieu 1998 92 offering an explanation for why some symbolic actions apparently play a larger role than other more environmentally serious consumption practices from this it is argued that the social structures underlying consumption and green behaviour should be recognised in the formulation of environmental policies and that instead of using sustainable practices such as environmental awareness as a sales argument more reflexive strategies that take consumers preferences into account should be considered

purchasing power parity a quantitative reassessment of the 1920s experience abstract the purpose of this paper is to test the hypothesis of purchasing power parity the basic methodology is to start by estimating a general distributed lag equation relating the excchangr rate to its own past and to current and past relative price levels successively more restricted version are then proposed and tested against the general model two interesting facts come out of this one is that the proportionality restrictin is not supported by the data and the other is that all the models estimated by frenkel 1978 are rejected in favor of less restricted models

proposal of a simple indicator for sustainable consumption classifying goods and services into three types focusing on their optimal consumption levels abstract we calculated optimal consumption patterns of japanese households using a linear programming model taking into account the different environmental burdens to be minimized ninety four industrial sectors and 94 commodities were defined in the model in terms of environmental burdens to be minimized this study considered energy consumption co 2 emission waste and no x emission according to the direction increase or decrease of adjusted final demand for a commodity in the household commodities were classified into three types 1 a commodity for which optimal demand should be decreased in all cases of reducing various environmental burdens 2 a commodity whose optimal demand should be increased in all cases and 3 a commodity whose optimal demand depends on the type of environmental burden among 63 commodities whose final demand was assumed to be adjustable 47 were categorized as commodity type 1 nine were categorized as commodity type 2 and seven belonged to commodity type 3 this work also characterized each type of commodity from the viewpoint of economic and environmental properties

residential energy use and conservation economics and demographics energy consumption in the residential sector offers an important opportunity for conserving resources however much of the current debate regarding energy efficiency in the housing market focuses on the physical and technical determinants of energy consumption neglecting the role of the economic behavior of resident households in this paper we analyze the extent to which the use of gas and electricity is determined by the technical specifications of the dwelling as compared to the demographic characteristics of the residents our analysis is based on a sample of more than 300 000 dutch homes and their occupants the results indicate that residential gas consumption is determined principally by structural dwelling characteristics such as the vintage building type and characteristics of the dwelling while electricity consumption varies more directly with household composition in particular income and family composition combining these results with projections on future economic and demographic trends we find that even absent price increases for residential energy the aging of the population and their increasing wealth will roughly offset improvements in the energy efficiency of the building stock resulting from policy interventions and natural revitalization

the impacts of china s household consumption expenditure patterns on energy demand and carbon emissions towards 2050 abstract this paper explores how china s household consumption patterns over the period 2005 2050 influence the total energy demand and carbon dioxide co2 emissions in two baseline scenarios and how it influences carbon prices as well as the economic cost in the corresponding carbon mitigation scenarios to this end we first put forward two possible household consumption expenditure patterns up to 2050 using the working leser model taking into account total expenditure increase and urbanization for comparison both expenditure patterns are then incorporated in a hybrid recursive dynamic computable general equilibrium model the results reveal that as income level increases in the coming decades the direct and indirect household energy requirements and co2 emissions would rise drastically when household expenditure shifts from material products and transport to service oriented goods around 21 000 mtce 1 of primary energy and 45 billion tons of co2 emissions would be saved over the 45 year period from 2005 to 2050 moreover carbon prices in the dematerialized mitigation scenario would fall by 13 in 2050 thus reducing the economic cost

does urbanization lead to more direct and indirect household carbon dioxide emissions evidence from china during 1996 2012 china is experiencing a stage of rapid urban development the energy consumption and related carbon dioxide emissions of households continue to increase this paper calculates direct and indirect carbon dioxide emissions of households based on the input output method in china from 1996 to 2012 the results reveal that there were more total carbon dioxide emissions from urban households than from rural households far more indirect emissions from urban households than from rural households slightly more direct emissions from urban households than from rural households and differences in direct carbon dioxide emissions from various fuels and in indirect emissions from various sectors between urban and rural households to examine the causal relationship between urbanization and the carbon dioxide emissions of households cointegration and granger causality tests are applied a unidirectional causal relation was found running from urbanization to both direct and indirect household carbon dioxide emissions and the direct and indirect carbon dioxide emissions of households would increase 2 9 and 1 1 respectively for every increase of one percent in urbanization we discuss the reasons of why the development of urbanization will lead to more household direct and indirect carbon dioxide emissions and suggest certain policy implications for urbanization and carbon dioxide emissions based on the results of this study

luxury or lock in an exploration of unsustainable consumption in the uk 1968 to 2000 abstract sustainable consumption demands the ability to understand the patterns of resource consumption associated with changing lifestyles this paper explores changes in resource consumption patterns in the uk between 1968 and 2000 using an environmental input output model the paper tracks the fossil resource requirements attributable to 8 high level functional purposes and finds that overall fossil resource consumption increased 35 over the 32 year period the four functional purposes most closely related to the provision of basic material needs showed little change over the period the bulk of the increase in fossil resource requirements was attributable to two specific functional purposes 1 recreation and entertainment 2 commuting and business travel the authors discuss the relevance of these findings for the continuing debate over the question whether rising consumption is being driven by expanding social aspirations luxury or whether it is the result of structural lock in

long memory in foreign exchange rates using the geweke porter hudak test we find evidence of long memory in exchange rate data this implies that the empirical evidence of unit roots in exchange rates may not be robust to long memory alternatives fractionally integrated autoregressive moving average arfima models are estimated by both the time domain exact maximum likelihood ml method and the frequency domain approximate ml method impulse response functions and forecasts based on these estimated arfima models are evaluated to gain insight into the long memory characteristics of exchange rates some tentative explanations of the long memory found in the exchange rates are discussed

policy options for the split incentive increasing energy efficiency for low income renters the split incentive problem concerns the lack of appropriate incentives to implement energy efficiency measures in particular low income tenants face a phenomenon of energy poverty in which they allocate significantly more of their household income to energy expenditures than other renters this problem is substantial affecting 1 89 of all united states energy use if effectively addressed it would create a range of savings between 4 and 11 billion dollars per year for many of the nation s poorest residents we argue that a carefully designed program of incentives for participants including landlords in conjunction with a unique type of utility managed on bill financing mechanism has significant potential to solve many of the complications we focus on three kinds of split incentives five concerns inherent to addressing split incentive problems scale endurance incentives savings political disfavor and provide a detailed policy proposal designed to surpass those problems with a particular focus on low income tenants in a u s context

housing wealth and residential energy consumption abstract the housing wealth effect often manifests as a positive relationship between consumption and perceived housing wealth e g the perceived value of houses when the perceived value of a property rises homeowners may feel more comfortable and secure about their wealth causing them to spend more this study adopts a behavioural approach to verify if this relationship holds true for residential energy consumption in the uk while controlling for property characteristics and a large number of demographic socioeconomic and energy use behaviour variables we identified a significant relationship between housing wealth and energy consumption our models also considered psychological biases in energy consumption behaviours such as the framing effect our findings shed light on the behavioural aspects of housing wealth effect on residential energy consumption and demonstrate the potential to nudge households towards energy conservation most importantly we provide empirical evidence on the intriguing relationship among housing wealth residential energy consumption and fuel poverty the findings of this study are particularly helpful in designing and implementing energy consumption policies that can strike a balance between social justice and economic efficiency

tailored advice and services to enhance sustainable household consumption in finland abstract household consumption for housing mobility food goods and services accounts for about 70 of finland s carbon footprint greenhouse gas emissions caused by the domestic final use of products therefore climate change mitigation calls for changes in human behaviour and consumption patterns opinion polls indicate that finns are concerned about climate issues at the same time the carbon footprint of household consumption in finland is high on a global scale it is clear that environmentally sustainable behaviour and decisions at the household level require knowledge motivation and services that support actions to tackle unsustainable consumption patterns action models promoting households environmental sustainability were developed and piloted in finland the action research approach was applied to study the process of development and piloting of the action models with key intermediaries and target groups involved in the process these action models were designed specifically to help households decrease their energy consumption and carbon footprint the action models provide tailored feedback and advice to address sustainable consumption from two perspectives 1 everyday sustainable choices and practices and 2 long term home renovation decisions in the action models the focus is on the most significant consumption choices therefore they also supplement finland s programme for sustainable consumption and production the pilot work demonstrates the role of the interactive process and feedback from target groups and intermediaries in significantly improving the action models the importance of personal contact for supporting household interpretation of numerical data and provision of tailored advice the role of intermediaries in disseminating research based knowledge and tools and that sustainability based perspectives in the renovation and housing maintenance sector can provide new and supplementary business opportunities

a micro econometric analysis of determinants of unsustainable consumption in the netherlands recently much attention has been given to the notion of sustainable consumption whereas environmental economics traditionally has focused environmental policy analysis on producers this new notion broadens the perspective to include environmental policies aimed at directly influencing consumer decisions regarding buying using and recycling products this could suggest policies that link not only to price incentives but also and especially to persuasive instruments such as education and information provision these policies might take into account certain characteristics of households such as lifestyle and family size this article presents a first econometric analysis of consumption in the context of environmental sustainability relationships between different types of household expenditures and a range of household characteristics are assessed based on a large micro data set of households for the netherlands use is made of various demand models and econometric techniques to adequately address theoretical and technical issues involved the article ends with a discussion of the implications of the results for environmental policy directed at stimulating sustainable consumption

a failure inducement model of research and development expenditure abstract empirical evidence for the schumpeterian suggestion of a positive relationship between profitability and innovative effort is slim in fact the opposite is often suggested an alternative failure inducement hypothesis argues that firms make innovative efforts when performance falls below a minimum threshold resulting in a negative relationship between profitability and r d expenditures data on r d expenditures in italian industry in the early 1980s a period of severe economic crisis show that both hypotheses are relevant for firms whose profits are well above or well below average respectively

a knowledge based theory of the firm the problem solving perspective in this paper we develop a knowledge based theory of the firm while existing knowledge based theory focuses on the efficiency of hierarchy in economizing on knowledge exchange we develop a theory of the firm that focuses on the efficiency of alternative organizational forms ingenerating knowledge or capability our theory begins with the problem as the basic unit of analysis arguing that a problem s complexity influences the optimal method of solution search and the optimal means of organizing that search the distinguishing feature that differentiates among organizational alternatives is the different way each resolves conflict over the selection of solution trials that is the way it chooses the path of search our theory predicts that efficiency demands that these governance alternatives be matched in a discriminating way to problems based on their associated benefits and costs in governing solution search thus our theory is among the first to simultaneously treat both the boundary choice i e internal versus external and the choice among alternative internal approaches to organizing

heterogeneity in german residential electricity consumption a quantile regression approach abstract in the absence of sufficient coverage of metering data on the electricity consumption of individual devices this paper estimates the contribution of individual appliances to overall household electricity consumption drawing on the most recent wave of the german residential energy consumption survey grecs moving beyond the standard focus of estimating mean effects we combine the conditional demand approach with quantile regression methods to capture the heterogeneity in electricity consumption rates of individual appliances our results indicate substantial differences in these rates as well as the end use shares across households originating from the opposite tails of the electricity consumption distribution this outcome highlights the added value of applying quantile regression methods in estimating consumption rates of electric appliances and indicates some scope for realizing conservation potentials

modelling sustainability performance to achieve absolute reductions in socio ecological systems as the world s natural resources dwindle and critical levels of environmental pollution are approached sustainability becomes a key issue for governments organisations and individuals with the consequences of such an issue in mind this paper introduces a unifying approach to measure the sustainability performance of socio economic systems based on the interplay between two key variables essentiality of consumption and environmental impact this measure attributes to every system a fitness value i e a quantity that reflects its ability to remain resilient healthy by avoiding ecological social and economic collapse as it consumes the available resources this new measure is tested on a system where there is a limited supply of resources and four basic consumption types the analysis has theoretical implications as well as practical importance as it can help countries organisations or even individuals in finding better ways to measure sustainability performance

the long run behavior of the real exchange rate a reconsideration using a new statistical test this paper provides empirical evidence that the real exchange rate is not a random walk if the real exchange rate were a random walk deviations from purchasing power parity could be expected to become unbounded as the forecast horizon became longer recently christopher a sims proposed a test based on bayesian posterior odds ratios that is designed to discriminate between a unit root and a large but stationary autocorrelation coefficient this paper applies the sims test to real exchange rate data for six industrial countries the results reject the random walk hypothesis copyright 1992 by ohio state university press

demographic effects on residential electricity and city gas consumption in the aging society of japan abstract japan has been confronted with two demographic forces declining fertility rates and lengthening life spans which give rise to the increasing ratio of the elderly aging society the decline in population and the prevalence of nuclear families this study empirically analyzes the demographic effects on residential electricity and city gas consumption in japan our analysis presents the following main results first the aging of the society decreases the electricity demand but does not affect the city gas demand significantly second the decrease in population with the prevalence of nuclear families increases the electricity demand but decreases the city gas demand the direction of the demand for each alternative depends on the balancing of the first and second effects third the analysis also shows clear results about the own and cross price effects ongoing energy market reforms for price suppression would increase energy demand with possible substitutability between the two energy sources our case study of japan is also applicable to other countries that will have just started to experience the similar demographic pattern of an aging society with energy market deregulation

rural residential energy transition and energy consumption intensity in china abstract this paper examines the impact of residential energy transition on residential energy consumption per capita recpc and identifies the underlying drivers in rural china based on province level panel data for years 1991 2014 in rural china it is shown that energy transition from traditional biomass energy tbe to traditional commercial energy tce significantly decreases recpc while energy transition from tbe or tce to advanced commercial energy ace significantly increases recpc as is revealed by the energy stacking model per capita income has a significantly negative impact on recpc and the impact of lagged recpc is opposite due to the regulation of energy price there exists price distortion in china s rural energy market and the price mechanism functions poorly besides factors including juvenile dependency ratio and education level significantly reduce recpc therefore it is vital to integrate rural energy into national energy strategic system facilitate energy transition process and introduce the market system reform of rural energy and continue to improve the education level of rural residents in rural china

energy consumption for space heating a discrete continuous approach energy demand for space heating is estimated using a discrete continuous choice model which focuses on the relationship between the choice of heating equipment and energy consumption the model is estimated on norwegian micro data and the two stages of the model are estimated simultaneously the capital cost and the operating cost of the heating systems are both found to have a significant impact on the choice of heating system furthermore the results show that household characteristics are important variables in residential energy models energy price elasticities and income elasticities are also estimated

allocating ecological footprints to final consumption categories with input output analysis we present and discuss a method that allows the disaggregation of national ecological footprints by economic sector detailed final demand category sub national area or socio economic group this is done by combining existing national footprint accounts with input output analysis calculations in the empirical part are carried out by using supply and use tables for the united kingdom covering the reporting period 2000 ecological footprints are allocated to detailed household consumption activities following the coicop classification system and to a detailed breakdown of capital investment the method presented enables the calculation of comparable ecological footprints on all sub national levels and for different socio economic groups the novelty of the approach lies in the use of input output analysis to re allocate existing footprint accounts in the detail of disaggregation by consumption category and in the expanded use of household expenditure data this extends the potential for applications of the ecological footprint concept and helps to inform scenarios policies and strategies on sustainable consumption the method described in this paper can be applied to every country for which a national footprint account exists and where appropriate economic and environmental accounts are available the approach helps to save time in data collection and improves the consistency between ecological footprint estimates for a particular human society from different researchers for these reasons the suggested methodology includes crucial steps on the way towards a standardisation of ecological footprint accounts

the carbon footprint of greek households 1995 2012 abstract the goal of this paper is twofold i to investigate the carbon footprint of greek households throughout the period 1995 2012 in order to identify the main socio economic factors that affect ghg emissions and ii to evaluate the effectiveness of the implemented policies to tackle climate change in this a consumption based emissions inventory approach is applied the analysis is based on an environmentally extended input output model including direct co2 emissions from households indirect co2 emissions from electricity consumption and indirect co2 emissions from energy used in the production of goods and services purchased by households domestic or imported statistical analysis and appropriate regression models were developed in order to identify the main factors influencing the carbon footprint of greek households the results indicate that the observed trends during the period 1995 2008 can be attributed to the effect of high economic growth this trend is partially counterbalanced by favorable weather conditions and the implementation of greenhouse mitigation policies and measures mainly in the supply side since 2008 the shrinking household income is the dominant driver in addition the effectiveness of energy conservation policies and measures in place is rather low while the effect of imports is limited

understanding the spectrum of residential energy saving behaviours french evidence using disaggregated data analysing household energy saving behaviours is crucial to improve energy consumption predictions and energy policy making how should we quantitatively measure them what are their determinants this study explores the main factors influencing residential energy saving behaviours based on a bottom up multivariate statistical approach using data from the recent french phebus survey firstly we assess energy saving behaviours on a one dimension scale using irt secondly we use linear regression with an innovative variable selection method via adaptive lasso to tease out the effects of both macro and micro factors on the behavioural score the results highlight the impact of five main attributes incentivizing energy saving behaviours based on cross variable analyses energy price household income education level age of head of household and dwelling energy performance in addition our results suggest that the analysis of the inverted u shape impact of age enables the expansion of the energy consumption life cycle theory to energy saving behaviours abstract analysing household energy saving behaviours is crucial to improve energy consumption predictions and energy policy making how should we quantitatively measure them what are their determi nants this study explores the main factors influencing residential energy saving behaviours based on a bottom up multivariate statistical approach using data from the recent french phebus survey firstly we assess energy saving behaviours on a one dimension scale using irt secondly we use linear regression with an innovative variable selection method via adaptive lasso to tease out the effects of both macro and micro factors on the behavioural score the results highlight the impact of five main attributes incentivizing energy saving behaviours based on cross variable analyses energy price household income education level age of head of household and dwelling energy performance in addition our results suggest that the analysis of the inverted u shape impact of age enables the expansion of the energy consumption life cycle theory to energy saving behaviours

subjective versus objective energy burden a look at drivers of different metrics and regional variation of energy poor populations abstract energy poverty is typically assessed using the energy expenditure to income ratio as a metric this metric fails to account though for residents demographics and regional variation in energy consumption in the united states policymakers dealing with energy poverty have faced challenges estimating the needs for energy assistance programs this study seeks to explore regional variations in energy poverty using texas as the region of study this work also explores differences in the populations captured via objective and subjective metrics i e those who are unable to pay their bill and those who state they struggle to do so drawing on survey data this work uses statistical analyses to 1 assess the regional variation of energy poverty defined as a ratio of household income spent on electricity bills 2 determine if there is an association between objective and subjective metrics of energy poverty and 3 identify statistical drivers of objective and subjective energy poverty metrics of respondents 51 of objectively energy burdened individuals indicated they struggled to pay electricity bills and 53 faced great stress due to the electricity bill if policymakers can use metrics that are more accurate in capturing populations facing energy poverty more effective energy poverty policies might be formulated

food and life cycle energy inputs consequences of diet and ways to increase efficiency food consumption is one of the most polluting everyday activities when impacts during product life cycles are considered greenhouse gas emissions from the food sector are substantial and need to be lowered to stabilise climate change here we present an inventory of life cycle energy inputs for 150 food items available in sweden and discuss how energy efficient meals and diets can be composed energy inputs in food life cycles vary from 2 to 220 mj per kg due to a multitude of factors related to animal or vegetable origin degree of processing choice of processing and preparation technology and transportation distance daily total life cycle energy inputs for diets with a similar dietary energy consumed by one person can vary by a factor of four from 13 to 51 mj current swedish food consumption patterns result in life cycle energy inputs ranging from 6900 to 21 000 mj per person and year choice of ingredients and gender differences in food consumption patterns explain the differences up to a third of the total energy inputs is related to snacks sweets and drinks items with little nutritional value it is possible to compose a diet compatible with goals for energy efficiency and equal global partition of energy resources however such a diet is far from the swedish average and not in line with current trends

a fractional cointegration analysis of purchasing power parity a generalized notion of cointegration called fractional cointegration is introduced to examine the long run purchasing power parity ppp hypothesis by allowing deviations from equilibrium to follow a fractionally integrated process the fractional cointegration analysis can capture a wider range of mean reversion behavior than standard cointegration analyses this gain is flexibility in modeling subtle mean reverting dynamics is found to be important for a proper evaluation of long run ppp empirical results based on historical data for the 1914 1989 period show that ppp reversion exists and can be characterized by a fractionally integrated process in three out of five countries studied the results support ppp as a long run phenomenon though significant short run deviations from ppp can exist

an empirical examination of long run purchasing power parity using cointegration techniques this paper presents an empirical analysis of long run purchasing power parity ppp for five major exchange rates using recently developed econometric techniques on the cointegration of economic time series our empirical results are extremely unfavourable to the ppp hypothesis as a long run equilibrium condition even with an allowance made for measurement error and or tranportation costs in particular we are unable to reject the hypothesis of non cointegration of the exchange rate and relative prices for any of the countries concerned far from finding a stable long run proportionality between exchange rates and relative prices our results therefore suggest that they tend to drift apart without bound

on the sources and significance of interindustry differences in technological opportunities abstract the set of technological opportunities in a given industry is one of the fundamental determinants of technical advance in that line of business we examine the concept of technological opportunity and discuss three categories of sources of those opportunities advances in scientific understanding and technique technological advances originating in other industries and in other private and governmental institutions and feedbacks from an industry s own technological advances data from the yale survey on industrial research and development are used to measure the strength of various sources of technological opportunity and to discern interindustry differences in the importance of these sources we find that interindustry differences in the strength and sources of technological opportunities contribute importantly to explanations of cross industry variation in r d intensity and technological advance

natural gas demand at the utility level an application of dynamic elasticities abstract previous studies provide strong evidence that energy demand elasticities vary across regions and states arguing in favor of conducting energy demand studies at the smallest unit of observation for which good quality data are readily available that is the utility level we use monthly data from the residential sector of xcel energy s service territory in colorado for the period january 1994 to september 2006 based on a very general autoregressive distributed lag model this paper uses a new approach to simulate the dynamic behavior of natural gas demand and obtain dynamic elasticities knowing consumers response on a unit time basis enables one to answer a number of questions such as the length of time needed to reach demand stability responses to price and income were found to be much lower even in the long run than has been commonly suggested in the literature interestingly we find that the long run equilibrium is reached relatively quickly around 18 months after a change in price or income has occurred while the literature implies a much longer period for complete adjustments to take place

residential energy use abstract the energy information administration recently published data they collected from the national interim energy consumption survey niecs niecs includes detailed information on 4081 individual households demographic characteristics energy related features of the structure heating equipment and appliances therein recent conservation actions taken by the household and fuel consumption and costs for the april 1978 march 1979 one year period this data set provides a new and valuable resource for analysis we summarized and analysed the niecs data on household energy consumption total energy use electricity use and use of the primary space heating fuel the regression equations constructed explain roughly half the variation in energy use among households these equations contain 10 or fewer independent variables the most important of which are fuel price year house was built floor area and heating degree days

long run purchasing power parity in the 1920s abstract this paper presents an empirical analysis of long run purchasing power parity ppp during the 1920s float using recently developed methodology on the cointegration of economic time series our results are generally supportive of ppp as a long run equilibrium condition on which exchange rates tended to converge over the period for dollar sterling however there is some evidence of a non stationary drift away from fundamentals during the last year or so before britain s return to the gold standard perhaps due to speculation our results also appear to reconcile some apparently conflicting evidence in the literature

equilibrium relationships between money and other economic variables central to the quantity theory of money are a number of important propositions about the long run equilibrium effects of changes in the nominal stock of money on other economic variables a standard way of testing these propositions is to use quarterly or annual data explicitly model the lag structure and then derive the long run solution of the model from the empirical estimates an alternative is to use some type of smoothing procedure to approximate positions of equilibrium and then to use these transformed data directly in testing hypotheses the national bureau technique of averaging data over reference cycle phases is one such method robert lucas s application of fourier transforms in two illustrations of the quantity theory of money 1980 is another and john geweke s method 1982 of frequency decomposition is a third an entirely different way of approaching the problem is to use cross country average rather than time series data as the basic units of observation the advantage according to lucas is that since the two quantity theoretic laws that he examines are obtained as characteristics of steady states or limiting distributions of theoretical models the ideal experiment for testing them would be a comparison of long term average behavior across economies with different monetary policies but similar in other respects p 1006 in this paper i conduct such an experiment the data that i use are for 20 oecd countries over the period 1956 80 the specific relationships that i examine are those between money and the price level money and real income money and interest rates and money and exchange rates in the main the data accord well with the quantity theoretic model classical neutrality holds there is evidence of a fisher effect albeit a less than complete effect on interest rates finally the data are consistent with long run purchasing power parity and hence correspondingly with a long run monetary approach to exchange rate determination

environmentally sustainable household consumption from aggregate environmental pressures to priority fields of action unsustainable consumption patterns of the north or rather of the global affluent consumers class have been identified by agenda 21 as one of the key driving forces behind the unsustainable development however neither accounting based on the system of national accounts sna nor household economics provide the proper instruments to assess the environmental impact of household decision making eco efficiency assessments as familiar in the business sector provide no appropriate tool for households as an alternative an environmental space based assessment scheme is suggested covering the major pressures on the environment caused by household decisions the methodology is used twice once to analyse the environmental relevance of the main activity clusters of household consumption and once to identify the dominant acts of consumption within each cluster the latter provide the basis for deriving environmental performance indicators a rough analysis of household influence potentials permits to identify housing eating and mobility as the three priority fields for action for minimising the environmental impact of households extending the influence analysis actor matrixes are derived allocating influence and thus responsibility for environmental pressures to different groups of economic agents

household consumption associated fossil fuel demand and carbon dioxide emissions the case of greece between 1990 and 2006 abstract this paper explores how greece s household consumption has changed between 1990 and 2006 and its environmental implications in terms of fossil fuel demand and carbon dioxide co2 emissions the results show that the 44 increase in greece s household expenditure between 1990 and 2006 was accompanied by a 67 increase in fossil fuel demand of this total indirect demand accounted for approximately 60 throughout the 16 year period increasing by 56 overall whereas direct fossil fuel demand grew by 80 the results also show that associated co2 emissions increased by 60 resulting in a relative decoupling from energy demand this relative decoupling is shown to be due to fossil fuel mix changes from the supply side rather than action from consumers these insights highlight the opportunities for demand side policies to further reduce fossil fuel demand and co2 emissions allowing greece to set more proactive and ambitious post kyoto targets

calculation and decomposition of indirect carbon emissions from residential consumption in china based on the input output model abstract based on the input output model and the comparable price input output tables the current paper investigates the indirect carbon emissions from residential consumption in china in 1992 2005 and examines the impacts on the emissions using the structural decomposition method the results demonstrate that the rise of the residential consumption level played a dominant role in the growth of residential indirect emissions the persistent decline of the carbon emission intensity of industrial sectors presented a significant negative effect on the emissions the change in the intermediate demand of industrial sectors resulted in an overall positive effect except in the initial years the increase in population prompted the indirect emissions to a certain extent however population size is no longer the main reason for the growth of the emissions the change in the consumption structure showed a weak positive effect demonstrating the importance for china to control and slow down the increase in the emissions while in the process of optimizing the residential consumption structure the results imply that the means for restructuring the economy and improving efficiency rather than for lowering the consumption scale should be adopted by china to achieve the targets of energy conservation and emission reduction

ghg reduction potential of changes in consumption patterns and higher quality levels evidence from swiss household consumption survey abstract an effective consumer oriented climate policy requires knowing the ghg reduction potential of sustainable consumption the aim of this study is to draw lessons from differences in consumption between households with high and low ghg emissions we evaluate a survey of 14 500 households and use a method that allows measuring changes in price level of consumption comparing the 10 of households with the highest ghg emissions per capita with the lowest 10 controlling for differences in expenditure level and household structure we find a range 5 17 tons of co2 equivalent per capita and year the observed differences stem mainly from heating electricity use car use and travel by aircraft consumption patterns with low ghg emissions are characterized by less spending on mobility but more on leisure and quality oriented consumption leading to higher prices per unit further characteristics are a higher share of organic food low meat consumption and fewer detached single family houses our findings imply that a significant reduction in ghg emissions would be possible by adopting real world consumption patterns observable in society the twin challenge is to shift consumption towards more climate friendly patterns and to prevent any trend towards high emitting consumption patterns

real exchange rates under the gold standard purchasing power parity is one of the most important equilibrium conditions in international macroeconomics empirically it is also one of the most hotly contested numerous recent studies for example have sought to determine the validity of purchasing power parity using data from the post bretton woods float and have reached different conclusions we assert that most such studies are flawed for two reasons first the post 1973 data contain by definition only a very limited amount of the low frequency information relevant for examination of long run parity second the dynamic econometric techniques used to model deviations from parity are typically quite crude with respect to admissible low frequency dynamics both deficiencies are rectified in the present paper with dramatic results we construct a new data set of 16 real exchange rates covering more than a century of the classic gold standard period and we study deviations from parity using long memory models that allow for subtle forms of mean

technological revolutions and techno economic paradigms this paper locates the notion of technological revolutions in the neo schumpeterian effort to understand innovation and to identify the regularities continuities and discontinuities in the process of innovation it looks at the micro and meso foundations of the patterns observed in the evolution of technical change and at the interrelations with the context that shape the rhythm and direction of innovation on this basis it defines technological revolutions examines their structure and the role that they play in rejuvenating the whole economy through the application of the accompanying techno economic paradigm this over arching meta paradigm or shared best practice common sense is in turn defined and analysed in its components and its impact including its influence on institutional and social change

diffusion of general purpose technologies understanding patterns in the electrification of us manufacturing 1880 1930 i examine the diffusion of the electric motor between 1880 and 1930 i find that long lag times are determined by the degree of technical difficulty in application after solutions became available electrification generally proceeded rapidly to make this claim i explore three industries urban transit printing and paper making i identify points at which viable electric solutions to particular problems were found and examine adoption patterns both before and after these events the explanation contrasts with common demand side explanations such as costly user adaptation or information diffusion and imposes conditions on the application of standard supply side models the results are particularly important when examining the diffusion of broadly defined technological categories such as general purpose technologies in the history of diffusion of many innovations one cannot help being struck by two characteristics of the diffusion process its apparent overall slowness on the one hand and the wide variations in the rates of acceptance of different inventions on the other rosenberg 1972 191 copyright 2005 oxford university press

long run versus short run behaviour of the real exchange rates this paper discusses the mean stationarity of real exchange rates by using new time series methods and new tests the question whether the real exchange rates have a unit root or are level reverting is set in the general and flexible framework of fractionally integrated processes the estimations and tests sustain the claim that real exchange rates may be nonstationary and not revert to any short run parity however estimations also suggest that real exchange rates behave differently on the short and on the long run and that they may revert to parity in a century long period

does the new economy measure up to the great inventions of the past abstract during the four years 1995 99 u s productivity growth experienced a strong revival and achieved growth rates exceeding that of the golden age of 1913 72 accordingly many observers have declared the new economy to be an industrial revolution even more important than the second industrial revolution of 1860 1900 which made the golden age of productivity growth possible this paper dissects the recent productivity revival subtracts out a cyclical component and concludes that there is no revival of the productivity growth trend in the 88 percent of the private economy lying outside of the durables manufacturing sector the paper explains this surprising finding by pointing to limitations in computers and the internet in comparison with the great inventions of the past

origins and pathways of innovation in the third industrial revolution this study examines the factors that shaped the long term evolution of the ict industry in sweden 1950 2013 using a new historical microdatabase on actual innovation output the driving forces and technological interdependencies in the third industrial revolution are chronicled the results of this study support some stylized facts about technological interdependencies in general purpose technologies a closely knitted set of industries have provided positive and negative driving forces for the development of ict innovations the historical evolution of gpts can in this perspective be described as a sequence of development blocks

residential energy demand additional empirical evidence by minority household type abstract in a number of recent studies household level data for specific urban areas or national household level micro data have been used to estimate price and income elasticities of energy demand none of this literature however provides us with elasticity estimates by minority majority household type the main focus of this paper is to measure the responsiveness of the quantity of electricity and total energy demanded for black hispanis and majority households to price and income price and income elasticities are compared among these groups over the short and long term a variable elasticity demand model is estimated the elasticities are allowed to vary with respect to non price and income variables the price elasticities of demand vary with heating and cooling degree days and the income elasticities with the number of household members mean estimates were calculated over the respective samples findings indicate that demand for electricity is relatively price inelastic irrespective of household group however blacks are more sensitive to variations in the short run to price than hispanic and majority households in the long run blacks are also more sensitive to price changes but the magnitude of the response to price changes in the long run relative to the short run is larger for hispanics and majority households respectively than for blacks

an in depth economic restructuring framework by using particle swarm optimization abstract the aim of this paper is the development of an integrated framework based on environmental input output analysis for optimizing the economic structure of an economy the restructuring process is approached as a constraint optimization problem where the optimized variables are the elements of the matrix of domestic technical coefficients a method for determining the optimal level of the productive linkages of an economy in order to maximize its output with the minimal greenhouse gas emissions the possible is suggested the proposed methodology is able to join both environmental and economic policy targets in the form of predefined constraints the objective function which is going to be minimized expresses the greenhouse gas emissions ghg intensity or ghg emissions per unit of output a particle swarm algorithm is employed for the solution of the optimization problem an illustrative application to the greek economy was carried out the experimental results revealed that if the greek economy will apply policies for boosting the sectors of high and medium high r d intensity then the greenhouse gas emission per unit of gross domestic product of greece would be reduced furthermore the promotion of high and medium high r d intensity sectors is connected with an important improvement of the production linkages to a wide range of sectors highlighting the important spillover effect of the suggested restructuring process

environmental regulation of households an empirical review of economic and psychological factors abstract the literature on sustainable consumption and environmental regulation of household behavior is dominated by conceptual and normative approaches as a result many suggestions lack a firm empirical basis to overcome this deficiency econometric studies in three areas of environmentally relevant activities of households are reviewed residential use of energy generation of solid waste and recycling and residential use of water next to price and income elasticities attention is devoted to individual socio economic features and psychological factors such as attitudes knowledge perceptions and values potential psychological determinants and related insights are further examined by discussing a range of representative and illustrative statistical psychological studies of environmental behavior one important general finding is that there are very few empirical studies that systematically combine socio economic and psychological determinants a range of insights for environmental policy is derived and research recommendations are offered

evaluation of the soft measures effects on ambient water quality improvement and household and industry economies abstract various ecological footprint calculators carbon footprint calculators and water footprint calculators have been developed in recent years the basic concepts of ecological behaviour record notebooks and of carbon dioxide emission calculators have been developed since the late 20th century the first carbon dioxide emission calculator was developed in 1991 likewise water pollutant discharge calculators have been developed to estimate the effects of soft measures introduced into households to reduce pollutant discharge since 2004 the soft measures which have been developed in japan may consist of a wider framework household sustainable consumption which has been developed in europe and can be referred to cleaner consumption in this research summarisation of the short history of ecological behaviour record notebooks and ecological footprint calculators in japan since the 1980s was conducted and the soft measures in households to reduce pollutant discharge were evaluated for their effects on ambient water quality improvement as well as household and industry economies effects of the soft measures on related industry economies were investigated using an input output table analysis and the effects of the imported goods were evaluated with an import effect matrix which was developed in this research the effects of the soft measures on household expenditures were estimated to be a decrease by 2 5 or usd 285 person 1 year 1 in 2003 2006 the results show that the soft measures positively affect the chemical fibre industry and significantly affect the detergent industry analysis of the import effect matrix proved that the six industries were tightly related through extensive amounts of imported goods the soft measures in households may lead to household sustainable consumption and thus reduce disadvantageous human impacts on water environments the effects of the measures introduced to improve the environment should be qualitatively and quantitatively evaluated to avoid redundant concerns and discord between the environment and the economy which may be worried when the relationship is not well understood

the indirect energy consumption and co2 emission caused by household consumption in china an analysis based on the input output method in recent decades china s rapid economy development has been coupling with the steadily increasing household consumption which in turn leads to ever growing energy consumption and co2 emission with a focus on the decade of 2000 2010 this study examines the energy consumption and co2 emission caused by household consumption using the input output method as well as the influencing factors of the indirect co2 emission the results show that first the indirect energy consumption and co2 emission appear the main parts of total energy consumption and co2 emission caused by household consumption accounting for 69 77 and 77 84 respectively second the indirect co2 emission indicates an increasing trend mainly driven by per capita household consumption and energy intensity finally the five sectors with relatively higher direct or total co2 emission intensity are the key sectors for reducing co2 emission in china i e 1 production and distribution of electric power and heat power pdeh 2 smelting and pressing of metals spm 3 processing of petroleum coking processing of nuclear fuel ppcpn 4 manufacture of non metallic mineral products mnm and 5 manufacture of chemical materials mcm

environmental consciousness of european consumers a segmentation based study abstract sustainable consumption is not a one dimensional phenomenon it entails various attitudinal and behavioural dimensions to promote sustainability decision makers are encouraged to recognise the heterogeneity of sustainable consumers the aim of this study was to examine a model of environmental consciousness and use its variables to segment european union eu consumers the study used a structural equation modelling approach to verify the environmental consciousness model and hierarchical agglomeration method for segmentation it was based on secondary data on environmental issues gathered in 28 eu member states personal attitudinal dimensions in the model explained a relatively high proportion of the variance in sustainable behaviour the segmentation analysis yielded three distinct segments that differ in their environmental consciousness and are affiliated with different eu country clusters the use of secondary data to a certain extent limited the analysis however its strengths are its scope the potential generalisability of the results and comparability based on eu data

procedures and criteria to develop and evaluate household sustainable consumption indicators abstract communication about very complex problems like household sustainable consumption in simple terms is still a major challenge despite the diversity of tools to measure household consumption clearer indicators are needed to more effectively communicate with the general public the main objective of this research was to develop an approach to define the main procedures and criteria to built household sustainable consumption assessment tools based on indicator sets a review of available household sustainable consumption assessment metrics and related initiatives was conducted this included a comparative analysis of the different approaches the review revealed that the majority of these initiatives are focused upon specific domains e g energy or waste but none used an integrated approach in the sustainable consumption domains furthermore it was found that few methods used indicators to measure and assess household sustainable consumption principal components and a checklist of key good practice factors that a household sustainable consumption indicator system should include were developed due to the need to communicate effectively to engage stakeholders and to address the complexity involved in the measurement and assessment of household sustainable consumption the proposed integrated approach was designed to evaluate household sustainable consumption

understanding the spectrum of domestic energy consumption empirical evidence from france abstract this article focuses on residential energy consumption in france using a bottom up statistical approach this analysis explores determinants of household energy consumption using data from the most recent national housing survey the primary objective is to tease out the impacts of various factors on the domestic energy consumption spectrum across different population groups the aim of this approach is to neutralize conventional factors affecting energy consumption age of house total area etc to finely analyze the impact of other determinants including those relating to household characteristics and other control variables first we define homogeneous consumption groups of households by using multivariate statistical techniques namely the multiple correspondence analysis and ascending hierarchical classification second we use standard ols regression to explore the effects of various factors on domestic energy consumption among homogeneous groups of households this multivariate analysis exercise has led us to identify four main consumption typologies results revealed that energy prices were the most important factors determining domestic energy consumption in addition this study showed that occupant characteristics significantly affect domestic energy use results of this research call for combine all efforts multiple strategies and smart policies to incorporate household and consumption behaviors in managing domestic energy consumption

the determinants of domestic energy consumption in france energy modes habitat households and life cycles this article explores the question of domestic energy consumption it concentrates on the example of france and using micro data from the 2002 and 2006 national housing surveys conducted by insee national institute of statistics and economic studies the empirical analysis is divided into three stages the first verifies the correspondences between modes of energy consumption household profiles and housing profiles in order to classify consumer mode types the second looks at the stabilities and variations over time of each of these types the last seeks to identify the causes of these changes the findings reveal sharp divergences between the factors affecting global consumption consumption per m2 and per person these variations can be explained by the impact of the demographic characteristics of households residential mobility and life cycles therefore these findings demonstrate the flexibility over time of domestic energy consumption which is still too often approached as a static variable solely associated with building characteristics they need to be taken further through a longitudinal and multidisciplinary approach to energy consumption patterns

a geographically and socio economically disaggregated local household consumption model for the uk abstract a key challenge for local environmental and economic planning is to predict resource flows and material waste arisings at a high level of geographical localisation this paper presents an approach to household consumption modelling in which the material demands of small socio economically homogeneous neighbourhoods are estimated on the basis of consumer expenditure data in conjunction with census data household waste arisings are estimated through incorporation of a household metabolism model selected material flows of consumer commodities such as household appliances carpets and clothing are examined in case study areas representing extremes of relative deprivation and neighbourhoods representing typical examples of the uk national output area classification oac the model will be of use in sustainable consumption policy making and local waste strategy planning

estimating energy conservation patterns of greek households abstract this paper develops an empirical model to investigate the main determinants of household energy conservation patterns in greece employing cross section data in the empirical analysis household energy conserving choices models are employed using a discrete and a latent trait variable respectively as a dependent variable the results show that socio economic variables such as consumers income and family size are suitable to explain differences towards energy conservation preferences in addition the results suggest that electricity expenditures and age of the respondent are negatively associated with the number of energy conserving actions that a consumer is willing to adopt finally other variables such as environmental information feedback and consciousness of energy problems are characteristics of the energy saver consumer by evaluating consumer s decision making process with regards to energy conservation measures we are able to formulate and propose an effective energy conservation framework for greece an energy policy framework is among the main prerequisites not only to achieve sustainable development but also to maintain consumers quality of life

effects of customized consumption feedback on energy efficient behaviour in low income households abstract smart metering and various consumption feedback systems can be used as applicable technology to encourage end use energy efficiency in the residential sector many studies have demonstrated the positive influence of socially contextualized feedback on the energy consumption of households but not many such studies dealt with the specifics of low income households this paper evaluates the effect of customized consumption feedback and other information interactions on energy behaviour patterns and energy savings in low income households the experimentation process was accompanied by an interactive awareness campaign with the emphasis being on a proper understanding of the consumption feedback and other complementary energy services provided to low income households the feedback actions were customized to tackle the recognised needs of each specific target household considering both the social aspects and the typology of the dwelling the results clearly confirmed the importance of customized information and efficiency indicators for specific household groups with a potential to increase knowledge and develop awareness with respect to established habits and their relevance to energy behaviour

an analysis of monthly household energy consumption among single family residences in texas 2010 demographic socioeconomic and housing characteristics influence variation in household energy consumption by combining household level utility public and proprietary data we examine predictors of household energy consumption in a texas urban area using quantile regression this analysis assesses the relationship between energy consumption and predictors at the middle and both ends of the distribution 10th and 90th percentiles results indicate potential opportunities to lower consumption among the highest energy consuming households including those with pools with non central cooling with people working from home those built on pier post foundation and those that are renter occupied these findings suggest significant opportunities to reduce consumption and demand as in the study area almost 10 of housing units are renter occupied 18 percent are without central cooling and 7 have pools capturing a significant portion of these homes for retrofit conservation efforts through marketing has potential to produce substantial results producing a better understanding of determinants of household energy consumption using the methods presented has potential to assist development and implementation of strategies to reduce consumption and increase efficiency

two illustrations of the quantity theory of money of two central implications of the quantity theory of money that a given change in the rate of change in the quantity of money induces i an equal change in the rate of price inflation and ii an equal change in nominal rates of interest the illustrations were obtained by comparing moving averages of the three variables in question using quarterly u s time series for the period 1953 77 readers may find the results of interest as additional confirmation of the quantity theory as an example of one way in which the quantity theoretic relationships can be uncovered via atheoretical methods from time series which are subject to a variety of other forces or as a measure of the extent to which the inflation and interest rate experience of the postwar period can be understood in terms of purely classical monetary forces the theoretical background of the study is reviewed very briefly as it is familiar material in the next section the data processing methods are described and rationalized in section ii the illustrations

understanding the spectrum of residential energy consumption a quantile regression approach abstract residential energy consumption accounts for 22 of the total energy consumption in the us however the impacts of local planning policies such as increasing density and changing the housing type mix on residential energy consumption are not well understood using residential energy consumption survey data from the energy information administration quantile regression analysis was used to tease out the effects of various factors on entire distribution on the energy consumption spectrum instead of focusing on the conditional average results show that while housing size matters for space conditioning housing type has a more nuanced impact self reported neighborhood density does not seem to have any impact on energy use furthermore the effects of these factors at the tails of the energy use distribution are substantially different than the average in some cases differing by a factor of six some not all types of multifamily housing offer almost as much savings as reduction in housing area by 100 m 2 compared to single family houses
