learning to believe in sunspots a number of authors have shown that competitive economies may possess sunspot equilibria that is rational expectations equilibria in which purely extrinsic uncertainty affects equilibrium prices and allocations 2 such results demonstrate that it does not require a lack of faith in the rationality of market participants to believe that competitive markets may be subject to purely speculative fluctuations driven solely by expectations 3 the mere existence of sunspot equilibria as solutions to a system of marketclearing conditions however might not be judged sufficient to indicate that competitive markets with rational participants could ever be subject to speculative instability the sunspot equilibria represent states of affairs in which agents act differently in the case of different realizations of the sunspot variable and it is rational for each agent to do so but it might be thought unlikely that the beliefs of all the participants in the market could ever come to be coordinated so as to bring about an equilibrium of that kind it is rational to believe that sunspots convey information about future states of affairs once the economy is in a sunspot equilibrium but why would rational agents ever begin to believe in such a thing so as to create the conditions under which the belief is rational in order to address such a question one must go beyond the mere statement of the conditions for equilibrium and discussion of what states of affairs satisfy them one must specify an explicit dynamic process according to which the beliefs of agents adjust when out of equilibrium any exercise of this kind is necessarily unsatisfactory as there is no univocal meaning for the postulate of rational behavior outside of an equilibrium it may well be the case that

dynamic multidimensional assessment of sustainability at the macro level the case of austria abstract this paper explores the issue of sustainability at the macro scale employing multi criteria decision aid mcda methods the incommensurability of values and the essentially multi dimensional and dynamic nature of sustainability challenge the use of composite measurement indices this determined the choice of mcda methods austria was chosen as a case study due to the wide availability of data especially on indicators of strong sustainability the structure of the multi criteria problem comprised the evolution of different sustainability dimensions over time the process for selecting criteria included a critical assessment of institutional sustainability agendas un eu and austrian government and theoretical recommendations after an assessment of mcda methods the naiade method demonstrated the most suitable properties for sustainability assessment the application of this outranking approach was undertaken in three separate settings long term from 1960 to 2003 medium term 1970 1995 and short term 1995 2003 with varying numbers of criteria the response of results to the addition of evaluating criteria and periods was tested the degree of credibility for accepting preference relations was also employed for sensitivity analysis according to the results of long term and medium term assessments especially in the weak sustainability setting sustainable progress is taking place in austria in the short term in the stronger sustainability setting and especially as the number of criteria increases more incomparable periods appear and trends are less determined moreover it is shown how results crucially depend on the methodological choices this is one of the first applications of the multi criteria tools to the dynamic analysis of sustainability at the macro scale

energy consumption and sustainable economic welfare in g7 countries a comparison with the conventional nexus abstract this is an empirical study on the causal relationship between sustainable economic welfare growth and energy consumption for canada france germany italy japan uk and the usa using a multivariate panel framework with variables such as employment capital energy consumption and r d the short and long run relationships are compared with those produced from the commonly known so far energy gdp gross domestic product growth relationship results mainly show that in the long run g7 economies can reduce energy consumption without compromising sustainable economic welfare in the short run though both gdp and economic welfare are very much dependent on energy consumption for their materialization of growth sustainable or not the current paper follows the tendency of new economics that shift their focus therein and propagate the use of sustainable welfare in place of the criticized gdp the calculation of the index for sustainable economic welfare isew reveals that uk closely followed by usa have the largest gap on average 52 and 50 respectively between their gdp and sustainable economic welfare japan is experiencing a steadily widening gap while canada is the most sustainable country among g7

application and use of the isew for assessing the sustainability of a regional system a case study in italy abstract the index of sustainable economic welfare isew was introduced by daly and cobb in 1989 in order to integrate the information embodied in gdp since economic growth implies externalities and market failures and a portion of it can be defined as uneconomic the isew method introduces some corrections and adjustments to the gdp calculation framework the isew has been calculated for a number of nations but it has been rarely applied to sub national systems its calculation at the local level is important especially in case of administrative decentralization and autonomy and responsibility of local authorities in certain fields for this reason a more and more comprehensive knowledge of the characteristics and peculiarities of the territorial system they manage is necessary this paper presents the results of the isew calculation for tuscany a region in central italy in the period 1971 2006 this is one of the few attempts to apply the isew in time series at the regional level final results show that a discrepancy between isew and gdp appeared in the 1970s social and environmental pressures increased during the period under study making the gap equal to about 30 percent of regional gdp in 2006 the isew can be used also as a tool for evaluating policies but further adjustments in calculation of certain items are considered necessary for taking into account and evaluating punctual policies a case of energy policy is presented

dynamic sustainability assessment the case of russia in the period of transition 1985 2008 abstract russia has experienced twenty years of economic and social change which had a substantial impact on the regional and sectoral patterns of the development of its economy infrastructure the quality of the environment and the well being of its people the current economic revival offers new opportunities and presents new challenges for the sustainable development of russia the paper employs the un sustainable development framework of indicators and assesses sustainability of russia using multi criteria evaluation methods namely the uncertainty randomization multi criteria evaluation method analysis and synthesis of parameters under information deficiency aspid the analysis covers economic environmental and social trends in russia s development in 1985 2008 and assesses sustainability of this development from the point of view of multiple criteria the results show the potential of employment of multi criteria methods for the sustainability assessment at the macro level and offer useful insights into multidimensional nature of sustainability and the role of priority setting in the evaluation process such an analysis reveals the degree of harmoniousness of sustainable development policy it shows how different sets of priorities determine the outcome of multidimensional analysis of sustainability and could potentially help in assessing progress and designing new policy instruments this paper is one of the first to apply multi criteria methods to the macro sustainability analysis in the dynamic setting

the index of sustainable economic welfare isew for a local authority a case study in italy abstract the index of sustainable economic welfare isew has been calculated for many countries but rarely at the local level this paper shows how the index has been calculated for the province of siena central italy the whole procedure is illustrated step by step including the search for the most suitable and precise methods to obtain reliable values for each item composing the index application of isew at a very local level was found to be feasible the most general difficulty encountered was the lack of an adequate institutionalised source of statistical information to support the construction of indicators other than purely economic or demographic ones this is mainly due to the still low interest for a sustainable management of natural resources and land on the part of local authorities and the related willingness to invest money and human resources on environmental research the isew gives a more realistic representation of the well being of the population than gdp since it includes environmental and social items not considered in conventional national accounting furthermore in italy the principle of administrative decentralization has been implemented in recent years to such an extent that the central government devolved part of its power to regions provinces and municipalities consequently local authorities are called to allocate more resources to pursue their policies towards sustainability an issue which modern electoral campaigns are often based on the results for the province of siena show that there is a large gap between local gdp and isew about 37 of gdp

economic growth and the evolution of material cycles an analytical framework integrating material flow and stock indicators abstract understanding the relationship between material cycles and economic growth is essential for relieving environmental pressures associated with material extraction production and consumption we developed an integrated analytical framework of dematerialization analysis incorporating both material flow and stock indicators a four quadrant diagram is designed to classify different stages of dematerialization based on the elasticity of material flow stock to economic output or well being we then conducted a case study on the long term evolution of aluminum cycle in the u s and found that different material flow and stock indicators decoupled from gross domestic product gdp growth in a clear sequential pattern flows closer to the beginning of the aluminum cycle e g primary aluminum production decoupled from gdp earlier than flows closer to the final consumption stage e g consumption of final products in use stock of aluminum decoupled from gdp much more slowly than any flow indicator and had just reached the status of relative decoupling around 2000 this phenomenon is determined by the fact that different causes of dematerialization such as import substitution and secondary material recycling take effect at different stages of economic development comprehensive understanding of dematerialization depends on in depth analysis on material economy relationships from an integrated stock and flow perspective

measuring sustainable welfare a new approach to the isew abstract sustainability and welfare assessment is a contemporary theme of major scientific and policy relevance requiring the consideration of multiple dimensions and diverse perspectives the economic approach to sustainability and welfare assessment has frequently relied on alternatives or adjustments to gdp widely used as an indicator of macroeconomic performance several authors have proposed alternative indicators such as the isew which intend to measure sustainability and economic welfare in a way that avoids the limitations of gdp namely accounting for the value of externalities the distribution of income and natural resources depletion since daly and cobb 1989 there have been proposed improvements to the isew however its aptitude to represent a sound alternative to gdp is still the subject of scientific debate this paper presents a new approach to the isew named modified isew including new components and methodological changes for the estimation of the index these have the purpose of avoiding some of the index shortcomings and allow for a direct comparison with the gdp which are advantages over previous studies an application is developed for the us case taking advantage of wide data availability and the possibility of comparing the results with previous works the results obtained provide a clearer picture of the success or failure of environmental and social policies namely by avoiding the tampering effect resulting from the cumulative accounting of environmental externalities this work also emphasizes the inadequacy of gdp as a welfare indicator as well as the need to develop and adopt alternative indicators

barriers and opportunities for alternative measures of economic welfare this paper explores a number of barriers and opportunities facing alternative measures of economic welfare by conducting semi structured in depth interviews with potential users in both belgium and germany the barriers that they identified are grouped into three categories context factors are embedded in the policy context and agendas that shape the environment in which an indicator percolates indicator factors depend on specific characteristics of the indicators while user factors relate to the level of experience and expertise of the users of indicators and the institutional culture in which they operate drawing on the different barriers that are reported we identify four opportunities to increase the policy value of alternative measures of economic welfare harmonizing and updating the methodological framework extending macroeconomic models to include a wider range of welfare related items improving the communication around these indicators and promoting indicator and researcher entrepreneurship these opportunities should be regarded as recommendations to the scientific community that works on these alternative measures the process of overcoming the different barriers listed in this paper should not be insurmountable as there is clear international public support for using health social and environmental statistics as well as economic statistics to measure societal progress and human well being

economic growth inequality and well being in advanced industrial societies rising levels of inequality have contributed strongly to the observed gap that has emerged between per capita income and the index of sustainable economic welfare isew which in its current versions is known as the genuine progress indicator gpi yet the isew gpi approach to measuring the social costs of inequality has been criticized as ad hoc the present paper reviews the literature on this topic and efforts to resolve it based on the construction of indicators grounded in a a classical utilitarian ethical framework and b empirical evidence on the relationship between income and well being in the united states after tax income per capita grew at an annual rate of 1 7 between 1979 and 2011 a growth rate of 1 2 per year arises when income is adjusted to account for the social costs of inequality the most common adjustment used in isew gpi studies yields a similar growth rate despite much smaller subtractions from baseline income

the index of sustainable economic welfare isew as an alternative to gdp in measuring economic welfare the results of the austrian revised isew calculation 1955 1992 abstract although the inadequacy of gdp to measure economic welfare is widely accepted theoretically it is still used as the key indicator for economic policy this article s aim therefore is to give some empirical evidence to the theoretical critique economic welfare or at least its change over time is estimated by the index of sustainable economic welfare isew which takes account of gdp unpaid household labor social costs environmental damage and income distribution the concept of the isew which was originally developed by herman daly and john cobb is entirely reformulated with special regard to questions of inner consistency and clarity in structure as an illustration the methods of the calculation in the austria case study and its results are presented the main result is that gdp and economic welfare as measured by the isew differ significantly up until the 1970s gdp only slightly overestimated the growth of economic welfare but since then it has been completely misleading while gdp continues to rise sustainable economic welfare has been stagnating since the middle of the 1980s the main causes have been growing future welfare reductions increasing income inequality and a stagnation in the value of unpaid household labor as gdp neglects those aspects it systematically misinterprets economic welfare however the isew does not intend to simply replace gdp as a unique welfare measure but should form part of a more holistic social reporting system

the sustainable welfare index towards a threshold effect for italy abstract gdp as a key parameter for macro economic policy has long been criticized one of the better known monetary alternatives to gdp is the isew a synthetic proxy of sustainable welfare theoretical and methodological limitations of this indicator have been identified and several refinements or extensions proposed gpi for example building on these approaches this article presents a new composite flow oriented indicator directly comparable with gdp the proposed sustainable welfare index swi is calculated for the italian case over the 1960 2014 period the estimate of swi over an extended period of fifty four years provides evidence for a previously undetected threshold effect in italy by means of a flow oriented indicator unlike gdp swi per capita stops increasing in 1991 empirical results show that the level of sustainable welfare in italy stops growing mainly because of a rise in income inequality a decline in non paid domestic work and a worsening of the net fixed capital formation and net international investment position

the genuine progress indicator methodological developments and results from australia abstract this paper is a contribution to the continuing development of the methods and results for the index of sustainable economic welfare also known as the genuine progress indicator gpi it attempts a more systematic approach to some of the components of the gpi it includes a more careful specification of types of capital and more plausible methods of estimating the costs of depletion of non renewable resources and environmental damage due to ozone depletion in addition the paper attempts a more comprehensive treatment of the value of time including the costs of unemployment and overwork results of the gpi calculations for australia over the period 1950 1996 are presented and analysed

economic openness and green gdp since the early 1990s there have been several attempts to develop national income accounting systems which recognize the negative impacts of environmental degradation and income inequalities on economic welfare collectively these bgreenq gross domestic product gdp studies have generated a wealth of new time series data sets which can be used to reexamine the links between gdp and a host of factors commonly included in traditional economic growth models in this paper we develop models of green gdp growth and the gap between traditional and green gdp by using a panel data set from eight countries spanning 30 50 years in both the growth and gap models the effects of economic openness are tested we find strong and robust results suggesting a negative nonlinear correlation between openness and green gdp growth and a positive nonlinear correlation between openness and growth of the gap between traditional and green gdp while green gdp accounting systems are still in their infancy our paper nonetheless implies that once these more comprehensive measures are fully developed empirical models which explore factors contributing to the growth of economic welfare over time should be reexamined d 2005 elsevier b v all rights reserved

a theoretical foundation to support the index of sustainable economic welfare isew genuine progress indicator gpi and other related indexes abstract for some time now ecological economists have been putting forward a threshold hypothesis the notion that when macroeconomic systems expand beyond a certain size the additional cost of growth exceeds the flow of additional benefits in order to support their belief ecological economists have developed a number of similar indexes to measure and compare the benefits and costs of growth e g the index of sustainable economic welfare isew and the genuine progress indicator gpi in virtually every instance where an index of this type has been calculated for a particular country the movement of the index appears to reinforce the existence of the threshold hypothesis of late a number of observers have cast doubt over the validity of these alternative indexes one of the concerns commonly expressed is the supposed lack of a theoretical foundation to support the isew the gpi and other related indexes by adopting a concept of income and capital outlined by fisher nature of capital and income a m kelly new york 1906 this paper demonstrates that these alternative indexes are theoretically sound but in order to be broadly accepted require the continuous development of more robust valuation methods

best nonparametric bounds on demand responses this paper uses revealed preference inequalities to provide the tightest possible best nonparametric bounds on predicted consumer responses to price changes using consumer level data over a finite set of relative price changes these responses are allowed to vary nonparametrically across the income distribution this is achieved by combining the theory of revealed preference with the semiparametric estimation of consumer expansion paths engel curves we label these expansion path based bounds on demand responses as e bounds deviations from revealed preference restrictions are measured by preference perturbations which are shown to usefully characterize taste change and to provide a stochastic environment within which violations of revealed preference inequalities can be assessed

equilibrium models displaying endogenous fluctuations and chaos abstract this paper surveys current developments in dynamic general equilibrium theory concerned with conditions under which endogenous fluctuations are possible existing contributions are divided into two classes the larger one consists of models with a unique perfect foresight equilibrium while the second includes models where equilibrium is indeterminate and the set of equilibria involving endogenous fluctuations includes sunspots equilibria while the two classes of models involve oscillations of different natures and with different policy implications we show that both are consistent with optimizing behavior and competitive equilibrium

non parametric tests of consumer behaviour the neoclassical model of consumer behaviour postulates that a consumer s choice behaviour can be described as deriving from utility maximization subject to a budget constraint one is then naturally led to ask what this model implies about observed behaviour this question has been addressed from two quite distinct approaches the first approach originating in the work of slutsky 1915 and antonelli 1886 derives necessary and sufficient conditions involving the derivatives of the demand functions the second approach originating in the work of samuelson 1938 1947 1948 derives algebraic conditions on the demand functions implied by maximizing behaviour

case study on the use of genuine progress indicator to measure urban economic welfare in china abstract the gross domestic product gdp has been widely used to measure the economic growth of a region or a country however it does not distinguish between economic activities that improve the well being and those that impair it it does not reflect the social economical and environmental sustainability either this paper presents a case study using the newly developed economic indicator genuine progress indicator gpi to evaluate the economic performance and human well being in china at an urban level the study also shows how the deficiencies of gdp in measuring the economic performance and well being can be overcome by gpi four cities in china suzhou and yangzhou in jiangsu province ningbo in zhejiang province and guangzhou in guangdong province were chosen in the case study important components of gpi for cost and benefit analysis were developed to address the depletion of nonrenewable resources cost of environmental pollution and net capital investment etc the comparison between gdp and gpi for the four cities and the comparison among the gpis of the four cities and other countries were made over the period of 1991 2001 based on the gpi results recommendations on policy making and infrastructural development were made for the improvement of the overall economic welfare of the cities the advantages and limitations of the gpi method were discussed

an index of sustainable economic welfare isew for chile abstract chile has experienced a period of strong economic growth the gross domestic product gdp has doubled in the past 12 years however income inequality remains relatively the same as in the 1960s the economic growth is primarily attributed to the exports of natural resources which accounts for 80 of total exports however the gdp fails to account for the loss of natural capital and non marketed services the objective of this paper is to more clearly indicate the status of the chilean economy in terms of welfare using the index of sustainable economic welfare isew designed by daly and cobb 1989 the isew provides corrections to the gdp that includes income inequalities household labor and damage to natural capital this index has been applied in several case studies for developed countries in general the results show that isew runs parallel with gdp until the 1970s when a decline in welfare occurs due to a loss in natural capital this study is the first attempt to utilize the isew for the purpose of analyzing whether or not similar trends exist for chile a developing country the isew for chile grew at a much slower annual rate over the past 30 years compared with gdp 0 16 vs 2 9 the chilean isew parallels the gdp until the 1980s a decline in the isew then occurs showing that chile is not on a sustainable path and that there is a strong link between economic growth and the depletion of natural resources

has australia surpassed its optimal macroeconomic scale finding out with the aid of benefit and cost accounts and a sustainable net benefit index abstract the sustainable economic welfare of a nation depends largely on the sustainable net benefits the macroeconomy confers to its citizens for this reason an optimal macroeconomic scale can be considered one where the physical scale of the macroeconomy and the qualitative nature of the stock of wealth it comprises maximises a nation s sustainable net benefits the corollary of this definition is thus the physical scale of the macroeconomy should grow only if in the process the sustainable net benefits of a nation increase it should cease to grow once sustainable net benefits are maximised whilst it is one thing to promote an optimal macroeconomic scale it is another entirely to gain an appreciation of the sustainable net benefits yielded by the macroeconomy gaining such an appreciation constitutes the central aim of this paper with the assistance of two separate benefit and cost accounts to replace gross domestic product gdp a sustainable net benefit index is constructed for australia for the period 1966 1967 to 1994 1995 the index particularly at the per capita level indicates that economic welfare in australia is declining i e the average australian is getting poorer despite per capita real gdp increasing the index therefore suggests that the scale of the australian macroeconomy has probably well exceeded the optimum

genuine progress indicator 2 0 pilot accounts for the us maryland and city of baltimore 2012 2014 abstract for over thirty years the genuine progress indicator gpi has been used to evaluate economic performance quantify benefits and costs of growth and predict effects of policy changes on economic wellbeing the popularity and use of the metric is increasing partially in response to new global demands for metrics that go beyond gross domestic product gdp however because the basic gpi accounting protocols have yet to be consistently updated to respond to theoretical critiques new valuation methods and new data sources a proliferation of studies at the global national and sub national level contain widely divergent methodologies because of this gpi practitioners have called for a new consistent framework to guide future gpi studies gpi 2 0 this paper is an attempt to operationalize some of the concepts that have emerged from gpi 2 0 deliberations online and at recent workshops in the form of gpi 2 0 pilot accounts for the us state of maryland and city of baltimore the goal is to demonstrate the feasibility of multi scale gpi accounts that provide a more accurate measure of current economic welfare than gdp and that incorporate new methods and sources of information to replace many of the outdated aspects of the prevailing gpi approach

on endogenous competitive business cycles the belief that the long run equilibrium of a competitive monetary economy that does not experience any exogeneous shocks whether originating from the external environment or from policy should be modelled as a state that is stationary or perhaps growing at a constant rate seems to be deeply rooted in the mind of some economists

nonparametric engel curves and revealed preference this paper applies revealed preference theory to the nonparametric statistical analysis of consumer demand knowledge of expansion paths is shown to improve the power of nonparametric tests of revealed preference the tightest bounds on indifference surfaces and welfare measures are derived using an algorithm for which revealed preference conditions are shown to guarantee convergence nonparametric engel curves are used to estimate expansion paths and provide a stochastic structure within which to examine the consistency of household level data and revealed preference theory an application is made to a long time series of repeated cross sections from the family expenditure survey for britain the consistency of these data with revealed preference theory is examined for periods of consistency with revealed preference tight bounds are placed on true cost of living indices

resource accounting in measures of unsustainability challenging the world bank s conclusions the world bank has recently published acomprehensive study of environmental and resourceaccounting covering 103 countries world bank1997a the study concludes that many sub saharan northern african and middle east countries have hadnegative genuine saving rates over the last 20years and therefore fail to pass the test of weaksustainability this paper argues that the bank sconclusions depend on a method for computing usercosts from resource exploitation that is challengedby two competing ones the el serafy method andthe method of repetto et al and is inferior to oneof its rivals resource rents are re computed usingthe el serafy method for 14 countries and thesub saharan and northern african and middle eastregions the results are that both regions andalmost all countries either stop exhibiting signs ofunsustainability or their unsustainability can beexplained without having recourse to resourceaccounting however for congo ecuador gabon nigeria mauritania and trinidad and tobago there isa lesson these countries did not adequately use theopportunities they were given through their naturalresource endowments and should learn from theirmistake for the future depletion of their remainingreserves of natural resources

the end of economic growth a contracting threshold hypothesis this paper argues that gdp growth in both developed and developing countries has associated costs that can outweigh the benefits and thus reduce sustainable well being this conclusion is based upon the findings of empirical applications of the genuine progress indicator gpi to a range of countries in the asia pacific region the studies conducted on seven asia pacific countries indicate that in the case of five of the seven nations more recent gdp growth has reduced the sustainable well being experienced by the average citizen residing within them moreover the threshold point at which the costs of gdp growth outweigh the benefits appears to be contracting i e occurring at a much lower per capita level of gdp this paper therefore introduces a new contracting threshold hypothesis as the economies of the asia pacific region and the world collectively expand in a globalised economic environment there is a contraction over time in the threshold level of per capita gdp as a consequence the threshold point confronting growth late comers i e developing countries occurs at a much lower level of sustainable welfare than what wealthy nations currently enjoy the consequences of this for developing countries are clearly significant and require a new approach to economic development

hidden linkages between resources and economy a beyond gdp approach using alternative welfare indicators taking gdp as the standard economic indicator for economic welfare recent resources economy studies indicate the dematerialization of the economy the so called decoupling effect this conclusion seems to alleviate concerns over resource scarcity and limits to growth and feeds optimism for green growth and sustainability prospects however the validity of gdp as the sole and unambiguous measure of the ultimate outcome of the economy has been severely disputed there is nowadays increasing interest in broader welfare measurements that capture more aspects of economic output and hence constitute better approximations of well being the present paper provides an overview of the above discussion and sets out to explore the relevance of three alternative welfare indicators the human development index hdi the index of sustainable economic welfare isew and the genuine progress indicator gpi as a basis for evaluating the dependency of welfare and its major engine the economy on natural resources increasing welfare appears to require a disproportionate use of resources strong and increasing dependency on resources at the global level and in giant countries such as china and india may have serious implications for current sustainability policies and the united nations sustainable development goals

welfare increasing third degree price discrimination when demand functions in different markets are derived from distributions of reservation prices that differ only in their means conditions exist such that third degree price discrimination leads to greater total output and greater total welfare welfare is higher with discrimination than with a uniform price when demand functions are derived from logistic distributions with different means welfare and consumer surplus are higher with discrimination for demands derived from a distribution related to the pareto in general whether discrimination increases total output depends on demand being more convex in markets in which prices fall with discrimination than in those in which prices rise

developing approaches to measuring and monitoring sustainable development in wales a review munday m and roberts a 2006 developing approaches to measuring and monitoring sustainable development in wales a review regional studies 40 534 535 under the 1998 government of wales act the welsh assembly government committed to the promotion of sustainable development in the exercise of its functions the paper examines a selection of approaches that are being explored in wales to monitor and measure progress towards sustainable development objectives these approaches are the ecological footprint the index of sustainable economic welfare the environmental satellite account and environmental input output tables the paper shows that in wales there are problems with each of the approaches outlined but that development of an environmental satellite account could be useful with this approach linked to the other approaches reviewed and with the satellite account enabling environmental factors to be connected more readily to conventional regional accounting aggregates the findings are expecte

a summary of isew and gpi studies at multiple scales and new estimates for baltimore city baltimore county and the state of maryland this paper 1 summarizes a number of previous index of sustainable economic welfare isew and genuine progress indicator gpi studies at various scales 2 estimates the gpi for baltimore baltimore county and the state of maryland and 3 compares these results with previous and parallel studies gpi incorporates environmental social and economic information into a single metric to represent economic well being at all three scales gpi was found to grow at a slower rate than the conventional economic measure of gross domestic product gdp while at the us national scale gpi has been relatively flat since 1975 state level results match an independently calculated maryland gpi confirming that gpi methods are robust and reproducible in addition the state of maryland has recently made gpi one of their official state statistics reported annually state level gpi results were also compared with studies for the states of ohio and vermont to explore regional differences we recommend that the gpi research community develop consensus on a standardized measurement approach and seek common ground for advancing the use of improved indicators and accounting systems in official policy settings

economic growth quality environmental sustainability and social welfare in china provincial assessment based on genuine progress indicator gpi abstract in order to devise scientific and sustainable development strategy it is vital to assess the quality of economic growth as a useful complement to traditional economic indicators gpi s most reputed virtue is its great improvement in evaluating environmental and social costs in this paper we estimate the gpi for all 31 provinces in mainland china from 1997 to 2016 gpi estimation is highly sensitive to income inequality climate change damage and depletion of non renewables we address contestable methodological assumptions associated with the three items which have been usually ignored in empirical studies we use the atkinson index in place of the gini index as a measure of income inequality we avoid the problematic duplicated counting of climate change damage and the unjustified cost escalation factor in depletion of non renewables our results show that first gpi per capita has recently declined in some provinces unveiling a threat to social welfare and sustainability second the relative threshold effect the progress of social welfare promotion is slower than the expansion of economic scale has been found in many provinces third resource consumption and environmental pollution especially water pollution and carbon emissions would generate substantial welfare losses

eductive expectations coordination on deterministic cycles in an economy with identical fundamentals abstract we study expectations coordination on a deterministic cycle of period 2 by an eductive approach in which agents are concerned with forecasting the forecasts of others this approach is grounded in some common knowledge assumptions we use this approach to discuss the problem of equilibrium selection between the stationary state and a cycle of period 2 we prove that locally eductively stable cycles of period 2 can exist if agents have stationary beliefs

valuation for renewable energy a comparative review abstract environmental cost benefit analysis is applied for the evaluation of renewable energy projects since some benefits and costs do not have monetary values economic valuation techniques are applied to estimate them this paper reviews the literature on the valuation evaluation of renewable energy resources and summarizes the methods used in them it discerns four main streams of valuation in renewable energy the first is economic welfare oriented and comprises stated and revealed preference methods the second is the financial option analysis with a financial background the third is emergy analysis which is mostly an ecological engineering based method with capable economic links and the fourth is again economic but not welfare based the paper discusses the main directions discerned in these studies and recognizes first that proper valuation takes place only in the first method while the other methods describe only evaluation procedures and second that there is a research gap that has yet to be filled in as compared to other areas of environmental resource and energy economics

eductive expectations coordination on deterministic cycles in an economy with heterogeneous agents abstract in this paper we study expectations coordination on a deterministic 2 cycle by an eductive approach in which agents are concerned with forecasting the forecasts of others this approach is grounded in some common knowledge assumptions we consider an overlapping generations economy in which agents have heterogeneous utility functions we show that locally eductively stable 2 cycles can exist when agents have stationary beliefs we also show that heterogeneity may hinder eductive coordination

on the methodology of isew gpi and related measures some constructive suggestions and some doubt on the threshold hypothesis existing country studies of the index of sustainable economic welfare isew the genuine progress indicator gpi and related measures while sharing the same basic methodological approach differ with respect to the valuation of important items this paper provides a critical but constructive discussion of the various methods used for the valuation of non renewable resource depletion and long term environmental damage and for the weighting of consumption expenditures for income inequalities several recommendations are given on how to improve the methodology for future updates of existing studies or for the construction of new measures sensitivity analysis shows that if these recommendations are followed for the valuation of resource depletion and long term environmental damage then the so called threshold hypothesis which seems to have gained empirical support from all studies undertaken so far fails to materialise this suggests that as far as factors related to the environment are concerned the widening gap between isew and gpi on the one hand and gross national product gnp on the other might be an artefact of highly contestable methodological assumptions 2000 elsevier science b v all rights reserved

revisiting isew valuation approaches the case of spain including the costs of energy depletion and of climate change abstract this paper develops an index of sustainable economic welfare for spain from 1970 to 2012 and seeks to update valuation approaches to a number of items two approaches have proven particularly controversial over recent decades the costs of energy depletion and of climate change the valuation implications in measuring present welfare have proven problematic as both include future sustainability consequences arising from resource depletion and environmental impacts this study includes a transition cost approach to energy depletion a modified approach to costs of climate change and water pollution and removes the cost of ozone depletion the results illustrate that while gdp per capita increased significantly the isew per capita shows a widening gap household labour contributes strongly but income distribution energy depletion and costs of climate change limit improvement sensitivity analysis shows that accumulating climate change costs and escalating energy depletion costs have significant effects nevertheless the new valuation approaches do not alter conclusions that welfare has shown little improvement the isew provides a useful alternative to current indicators such as gdp subject to awareness of limitations it is a measure of welfare that uses sustainability accounting methods when estimating costs but is not an indicator of whether welfare is actually sustainable

estimates of the genuine progress indicator gpi for vermont chittenden county and burlington from 1950 to 2000 the genuine progress indicator gpi a version of the index of sustainable economic welfare isew is a significantly more comprehensive approach to assessing economic progress than conventional measures like gross domestic product gdp gpi adjusts for income distribution effects the value of household and volunteer work costs of mobility and pollution and the depletion of social and natural capital isew or gpi have been estimated for several countries around the world and a few canadian provinces but we report here on the first multi scale application at the city county and state levels in vermont usa we show that it is feasible to apply the gpi approach at these smaller scales and to compare across scales and with the national average data limitations and problems still exist but potential solutions to these problems also exist all three vermont scales had significantly higher gpi per capita since 1980 than the national average indicating the major differences that can exist within countries the gpi per capita for all vermont scales was similar to the national average in the 1950 1980 period but more than twice the national average by 2000 the main factors explaining this difference had to do with vermont s much better environmental performance than the national average in the post 1980 period d 2004 elsevier b v all rights reserved

proposed changes to the index of sustainable economic welfare an application to belgium abstract this paper presents the results of a belgian case study on the index of sustainable economic welfare isew the index is first compiled using the standard methodology applied in other international studies owing to the short period in which belgium s traditional isew has recently declined it is not possible to draw any solid conclusion regarding max neef s threshold hypothesis after a brief review of the criticism that the isew has attracted over the years the paper then explains and discusses the rationale for omitting the net capital growth and change in net international investment position items it is argued that these items do not comply with the theoretical foundation underpinning the isew the paper also puts forward new valuation methods for several items within the index the escalation factor in the valuation of natural capital depletion is dropped long term environmental damage is valued using a stock based approach and considerably more government expenditures are considered to be non defensive the results of the revised isew show significant improvements in sustainable economic welfare over the entire study period these findings are not in line with the threshold hypothesis finally the paper offers some guidelines for communicating about the isew namely that a all methodological assumptions should be made explicit and b all raw unadjusted data used should be included in any final isew report so as to enable the reader to make his or her own assessment about the assumptions the researcher has employed
