how responsible is a region for its carbon emissions an empirical general equilibrium analysis targets for co2 reduction tend to be set in terms of the amount of pollution generated within the borders of a given region or nation that is under a production accounting principle however in recent years there has been increased public and policy interest in the notion of a carbon footprint or the amount of pollution generated globally to serve final consumption demand within a region or nation that is switching focus to a consumption accounting principle however this paper argues that a potential issue arising from the increasing focus on consumption based carbon footprint type measures is that while regional co2 generation embodied in export production is attributed outside of the region i e to the carbon footprints of other regions nations regional consumers are likely to benefit from such production moreover where there is a geographical and supply chain gap between producers and final consumers it may be difficult to identify precisely whose carbon footprint emissions should be allocated to

a factor analytic probit model for representing the market structure in panel data internal market structure analysis infers both brand attributes and consumer preferences for those attributes from preference or choice data the authors exploit a new method for estimating probit models from panel data to infer market structures that can be displayed in few dimensions even though the model can represent every possible vector of purchase probabilities

energy in a regional economy a computable general equilibrium model for california abstract this study presents a model of energy in the california economy and uses it to simulate long run impacts of oil price changes under varying assumptions about the structure of the economy the distinguishing feature of the model is flexibility use of generalized leontief flexible cost functions at the sectoral level captures the substitution effects of relative price changes while at the same time retaining the structure of traditional input output analysis experimental results suggest this innovation can be important a doubling of the price of imported oil leads to a much larger drop in oil use and a substantially smaller drop in aggregate consumption than is obtained with a fixed coefficient version of the model

shared producer and consumer responsibility theory and practice abstract over the past decade an increasing number of authors have been examining the nexus of producer versus consumer responsibility often dealing with the question of how to assign responsibility for internationally traded greenhouse gas emissions recently a similar problem has appeared in drafting the standards for the ecological footprint while the method traditionally assumes a full life cycle perspective with full consumer responsibility a large number of producers businesses and industry sectors have started to calculate their own footprints see www isa org usyd edu au adding any producer s footprint to other producers footprints or to population footprints which all already cover the full upstream supply chain of their operating inputs leads to double counting the sum of footprints of producers and consumers is larger than the total national footprint the committee in charge of the footprint standardisation process was hence faced with the decades old non additivity problem posing the following dilemma for the accounting of footprints or any other production factor if one disallows double counting but wishes to be able to account for producers and consumers then one cannot impose the requirement of full life cycle coverage the supply chains of actors have to be curtailed somehow in order to avoid double counting this work demonstrates and discusses a non arbitrary method of consistently delineating these supply chains into mutually exclusive and collectively exhaustive portions of responsibility to be shared by all actors in an economy

consumer preference for a no choice option the traditional focus in the decision making literature has been on understanding how consumers choose among a given set of alternatives the notion that preference uncertainty may lead to choice deferral when no single alternative has a decisive advantage is tested in seven studies building on recent research the article shows that the decision to defer choice is influenced by the absolute difference in attractiveness among the alternatives provided and is not consistent with trade off difficulty or the theory of search these findings are then extended to show that choice deferral can also be modified for the same alternatives by manipulations that make them appear more similar in attractiveness or that decrease the need to differentiate among them the results are consistent with the notion that preference uncertainty results in a hesitation to commit to any single action since small differences in attractiveness among the alternatives are potentially reversible consistent with this premise the effect of attractiveness difference on choice deferral decreased significantly when subjects were first allowed to practice making monetary trade offs among the available alternatives

a review of recent multi region input output models used for consumption based emission and resource accounting abstract the interest in consumption based emission and resource accounting has grown significantly many studies juxtapose consumer emissions carbon footprint and producer territorial emissions of greenhouse gases in order to demonstrate the effects of trade on the national emission budget to this end a respectable number of studies have been undertaken worldwide in order to estimate emissions embedded in international trade of numerous countries and world regions input output approaches and increasingly multi region input output mrio models are commonly chosen as they provide an appropriate methodological framework for complete carbon footprint estimates at the national and supra national level with increasing processing capabilities of computers and a wider availability of economic accounts environmental accounts and trade data such models are now being implemented on a wide scale after a brief overview of salient single region input output studies i provide an in depth review of the most recent multi region input output models used for the purpose of consumption based environmental accounting the main methodological features and important results are described for around twenty studies covering the years 2007 to 2009 this is followed by a detailed review of studies dealing with uncertainty in mrio analysis an area which has not received a lot of attention so far i conclude that further research is mainly needed in two areas a improvements in data availability and quality and b improvements in the accuracy of mrio modelling

a framework to account for the tourism carbon footprint at island destinations abstract given concerns over greenhouse gases and the role of tourism in generating such environmental externality a consistent carbon measurement framework is needed this paper combines principles derived from production and consumption accounting measures to better allocate the responsibility for carbon emissions utilizing a boundary that includes domestic tourism expenditure inbound tourism expenditure and local spending associated with outbound travel this paper a proposes a framework to measure the domestic total carbon effect and foreign sourced effect and b applies the analytical framework to taiwan the empirical study indicates that the carbon emissions for domestic tourism industries international aviation and imports accounted for 47 28 and 25 of the tourism carbon footprint it is suggested that an island s dependence on both aviation and international trade leads to a larger share of emissions outside their geographic territory with respect to tourism development

age analysis of the impact of a carbon energy tax on the irish economy a computable general equilibrium model with specific detail in taxation and energy use is developed in this paper to quantify the impact of the implementation of energy taxation to reduce carbon dioxide emissions in ireland benchmark data combining physical energy and emissions data and economic data in the form of a social accounting matrix sam had to be compiled from various data sources because energy and pollution accounts from the seea are not available for ireland we find that the reduction target for energy related co2 emissions in ireland of 25 8 compared to 1998 levels can be achieved with a carbon energy tax of 10 15 euros per tonne of co2 though fuel switching is important in meeting the target this result is more sensitive to the possibilities for producers to substitute away from energy use welfare would fall but only by small percentages production and consumption patterns would change more significantly with a shift in demand from fuels with a high emission factor to energy sources with a lower carbon intensity and from energy to other commodities this paper confirms that a carbon energy tax leads to greater emission reductions than an equivalent uniform energy tax the latter has a stronger negative impact on the less polluting energy sectors whereas the carbon tax greatly stimulates the use of renewable energy and reduces the use of peat and coal the new sam the model and the application to energy taxes contribute to a better informed debate on environmental policy in ireland

emissions in a decarbonised economy global lessons from a carbon footprint analysis of iceland abstract decarbonisation of stationary energy supply particularly electricity grids is the current focus of climate change mitigation policy however studies have suggested that this narrow policy focus is insufficient to achieve meaningful global emissions reductions using iceland as a case study this paper demonstrates that significant emissions arise from transport and imported products which are often not fully captured in territorial ghg inventories this results in high greenhouse gas emissions per capita regardless of the nation s domestic energy supply the result is a low carbon illusion in which rich economies believe they are reducing their ghg responsibility whilst global emissions continue to grow this paper presents the first consumption based carbon footprint cbcf analysis for iceland a nation where the stationary energy supply is 99 renewable and could be viewed as a decarbonisation future case for rich nations globally the study combines icelandic household expenditure data with the multi regional input output database eora to calculate the cbcf of icelandic households the average annual cbcf of icelandic households was 10 4 tco2eq capita similar in magnitude to other eu nations despite iceland s unique energy supply ghg emissions from transport food and goods dominated the household cbcf the national cbcf was higher than most european nations and 55 higher than the territorial emissions inventory approximately 71 of household emissions were attributed to imported goods which were mapped globally revealing that the ghg emissions burden of icelandic consumption falls primarily on developing nations the findings suggest that a broader ghg accounting framework and resulting policy focus is required both in iceland and globally that incorporates both supply and demand based ghg reduction strategies

the role of explanations and need for uniqueness in consumer decision making unconventional choices based on reasons this research investigates the interaction between a very common task explaining decisions and an individual difference need for uniqueness nfu on buyer decision making we propose that explaining or providing reasons for decisions shifts the focus from the choice of options to the choice of reasons furthermore buyers who explain their decisions and have high nfu tend to select unconventional reasons and are consequently more likely to make unconventional choices these predictions were supported in a series of studies involving choices between conventional and less conventional options such as whether to switch to a brand on sale whether to select a compromise option and whether to accept a gamble with a possible loss the findings also indicate that the effects of providing reasons are not due to attempts to act rationally or to concerns about being evaluated three boundary conditions on the generalization that high nfu consumers who provide reasons tend to make unconventional choices we

modelling regional policy scenarios in the agri food sector a case study of a spanish region abstractthe agri food industry has several features of great importance for sustainable economic growth in rural areas the objective of this work is to evaluate the effects associated with different scenarios of growth and changes in the regional agri food industry these scenarios simulate changes in exports and imports changes in technology and changes in the level of industrial integration we develop a computable general equilibrium model calibrated for the region our results indicate that policies trying to improve the competitiveness and dynamism of strategic sectors as the agro industrial complex in this regional economy exert positive effects on its growth and income having notable impacts on local job markets but also in other sectors and activities linked through the whole production chain

the impact of private versus public consumption on variety seeking behavior three experiments demonstrate that people incorporate more variety into their consumption decisions when their behavior is subject to public scrutiny studies 1 and 2 indicate that consumers expect others to evaluate their decision more favorably if they choose variety and that this sometimes leads individuals to incorporate more variety into their public than private decisions results of study 2 confirm predictions that a relevant individual difference variable self monitoring moderates the effects of expected evaluation on variety seeking the final study demonstrates that pressure to choose variety in public is eliminated when a social cue signals the appropriateness of consuming one s favorites

identifying the hand of past distinguishing state dependence from heterogeneity a basic problem in social science is to ascertain the importance of initial endowments on subsequent outcomes of a dynamic process interest in this topic centers on two distinct issues a do initial endowments have a temporally persistent effect on outcomes i e is there heterogeneity b are the effects of initial endowments attenuated or accentuated by subsequent experiences of the process being studied or by related processes i e is there state dependence these two questions show up in a variety of contexts 1 the importance of family background on a person s subsequent education and earnings is a hotly debated topic do market or nonmarket mechanisms reinforce or diminish initial endowments 2 the incidence of criminal activity is concentrated among a small population of repeated offenders are certain persons prone to criminality or does crime breed crime 3 are persons who experience unemployment more likely to experience future unemployment due to loss of work experience or market stigma 4 does early entry into an industry confer an advantage of incumbency or does it merely proxy the basic managerial and innovative ability of early entrants many formal models of state dependent processes or processes with persistent effects of initial conditions have been formulated invariance of steady states to initial endowments was viewed as a desirable feature of an economic model in the 1960 s and 1970 s path dependent synergism and nonergodicity are fashionable features of models today is the choice between models with long run dependence on initial conditions and those without solely a matter of intellectual esthetics can data discriminate between these two classes of models how many economically extraneous statistical regularity conditions have to be imposed in order to distinguish between these models how many and what kind of maintained assumptions are required in order to let the data speak on these important questions in this paper i focus on one nonergodic model that receives much attention in the literature the model of duration dependence and heterogeneity discussed by herbert silcock 1954 and also examined by tony lancaster 1979 chris elbers and geert ridder 1982 myself and burton singer 1984 and myself and bo honore 1989

self control for the righteous toward a theory of precommitment to indulgence prior research has examined consumers use of self control to avoid hedonic myopic temptations such as overspending and smoking in this research we investigate the opposite form of self control whereby consumers force themselves to indulge and avoid default forms of spending on utilitarian necessities and or savings in particular consumers who have difficulty choosing items that are perceived as indulgences or luxuries e g a cruise over necessities e g saving for college education and cash in everyday decisions may use precommitments to indulgence especially when the psychological cost of such commitments is less concrete these propositions were tested in a series of studies involving real and hypothetical choices as well as process measures the results indicate that a substantial segment of consumers choose hedonic luxury rewards over cash of equal or greater value consumers typically explain such choices based on the need to precommit to indulgence to make sure that the award does no

regional employment impacts of marine energy in the scottish economy a general equilibrium approach gilmartin m and allan g regional employment impacts of marine energy in the scottish economy a general equilibrium approach regional studies one aspect of the case for policy support for renewable energy developments is the wider economic benefits that are expected to be generated within scotland as with other regions of the uk there is a focus on encouraging domestically based renewable technologies this paper uses a regional computable general equilibrium framework to model the impact on the scottish economy of expenditures relating to marine energy installations the results illustrate the potential for considerable legacy effects after expenditures cease in identifying the specific sectoral expenditures with the largest impact on lifetime regional employment this approach offers important policy guidance

a dynamic analysis of market structure based on panel data internal market structure analysis infers brand positions in an attribute space from preference and choice data given a market in which consumers have heterogeneous tastes for attributes previous market structure models have adopted a static framework e g elrod 1988 chintagunta 1994 elrod and keane 1995 furthermore they assumed that consumer perceptions of brand attributes do not vary across consumers yet these approaches may render inaccurate representations of market structure if there is state dependence in consumer choice behavior this paper attempts to incorporate consumer choice dynamics into market structure models by specifying the source of choice dynamics explicitly in particular the process by which past purchases affect current choices is modeled in a framework which captures both consumer habit persistence and variety seeking behavior more specifically consumer preferences for brand attributes are modeled to depend on the attributes of brands bought on the previous purchase occasion furthermore the modeling approach adopted incorporates heterogeneity in both consumer preferences and perceptions of brand attributes the audience of this paper includes practitioners and academics interested in understanding consumer choice processes and inferring market structure from consumer choice data the proposed models are estimated on nielsen scanner panel data for margarine peanut butter yogurt and liquid detergent using simulated maximum likelihood techniques the empirical results suggest that accounting for choice dynamics improves both in sample and out of sample fit the results indicate that the average consumer is habit persistent in all the product categories studied this result is consistent with the findings of kannan and sanchez 1994 who conducted an aggregate analysis of consumer variety seeking behavior across product categories however the results obtained in this paper suggest that consumers are heterogeneous with respect to the processes by which past purchases affect current purchases these results provide strong evidence for habit persistence and variety seeking in brand attributes to be the behavioral source of consumer choice dynamics in food categories thus consumer tastes utility weights seem to be affected by the attributes of the brands consumed in the past given the empirical result that a large proportion of consumers are habit persistent this suggests that tastes are reinforced by the brand attributes consumed in the past the empirical results also show that not accounting for state dependence in market structure models for panel data may produce misleading results that is depending on consumer behavior patterns models that do not account for state dependence may distort the true nature of competition among brands more specifically the results confirm the expectation that if there is habit persistence that is if consumer tastes are reinforced by attributes of brands consumed in the past models that do not capture this choice dynamics will overestimate the distance between similar brands furthermore the policy experiments conducted suggest that 1 static models overestimate the short run impact of a price cut on the sales of the brand on promotion 2 price cuts hurt the sales of the more similar brands more and 3 free samples affect relatively less similar brands the most finally this paper studies variety seeking and habit persistence across brands over purchase occasions however variety seeking behavior may also involve the purchase of a portfolio of brands or items at a purchase occasion consumers may buy multiple items knowing that prior to the next trip they may want to consume different items simanson 1990 walsh 1995 this type of behavior can be modeled within the context of dynamic expected utility maximization with forward looking consumers the development and estimation of market structure models that include forward looking consumers who maximize expected utility over a planning horizon incorporating their future tastes and needs and shopping for an inventory of brands remain an important future research issue

do increases in energy efficiency improve environmental quality and sustainability governments world wide increasingly see energy efficiency as an important aspect of sustainability however there is a debate in the literature as to whether the impact of improved energy efficiency on reducing energy use might be partially or more than wholly offset through rebound and backfire effects this paper clarifies the theoretical conditions under which such effects would occur and explores their likely significance using a computable general equilibrium cge model of the scottish economy we find that for scotland a general improvement in energy efficiency in the production sectors of the economy initially produces rebound effects that eventually grow into backfire energy use ultimately increases in response to an efficiency gain and the ratio of gdp to co2 emissions falls the economic factors underpinning rebound effects are straightforward energy efficiency improvements result in an effective cut in energy prices which produces output substitution competitiveness and income effects that stimulate energy demands however the presence of strong rebound or even backfire does not mean that efficiency enhancing policies are irrelevant rather it suggests that such policies operating alone are insufficient to generate environmental improvements the implication is that a co ordinated portfolio of energy policies is required

choice based on reasons the case of attraction and compromise effects building on previous research this article proposes that choice behavior under preference uncertainty may be easier to explain by assuming that consumers select the alternative supported by the best reasons this approach provides an explanation for the so called attraction effect and leads to the prediction of a compromise effect consistent with the hypotheses the results indicate that 1 brands tend to gain share when they become compromise alternatives in a choice set 2 attraction and compromise effects tend to be stronger among subjects who expect to justify their decisions to others and 3 selections of dominating and compromise brands are associated with more elaborate and difficult decisions

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

examining the global environmental impact of regional consumption activities part 1 a technical note on combining input output and ecological footprint analysis in recent years there have been a number of attempts to develop a more comprehensive approach to the issue of measuring resource use and or pollution generation embodied in trade flows including contributions that combine input output techniques and ecological footprint analysis in this two part paper we describe how to enumerate the resource and or pollution content of inter regional and inter national trade flows part 1 and we present a literature review of recent methodological and empirical developments part 2 it is straightforward in principle to extend the basic input output approach to capture international trade flows however in practice problems of data availability and compatibility and of computability of extended input output matrices mean that simplifying assumptions are generally applied but with the implications of these assumptions often not made fully explicit what appears to be absent from previous applications is an account of the analytical method by which ecological footprints should ideally be estimated in an international input output accounting analysis this allows an explicit analysis of the problems that prevent the application of the full method and identification of the most appropriate short cut methods in a transparent way the objective of this paper is to provide such an account

multiple routes to self versus other expression in consumer choice abstract studies of consumer decision making often begin with the identification of a dimension on which options differ followed by an analysis of the factors that influence preferences along that dimension building on a conceptual analysis of a diverse set of problems the authors identify a class of related consumers choices e g extreme vs compromise hedonic vs utilitarian risky vs safe that can all be classified according to their levels of self versus other expression or un conventionality as shown in four studies these problem types respond similarly to manipulations that trigger or suppress self expression specifically priming self expression systematically increases the share of the self expressive options across choice problems conversely expecting to be evaluated decreases the share of the self expressive options across the various choice dilemmas in addition priming risk seeking increases only the choice of risky gambles but not of other self expressive options these find

consumer choice between hedonic and utilitarian goods abstract in this article the authors examine how consumer choice between hedonic and utilitarian goods is influenced by the nature of the decision task building on research on elaboration the authors propose that the relative salience of hedonic dimensions is greater when consumers decide which of several items to give up forfeiture choices than when they decide which item to acquire acquisition choices the resulting hypothesis that a hedonic item is relatively preferred over the same utilitarian item in forfeiture choices than in acquisition choices was supported in two choice experiments in a subsequent experiment these findings were extended to hypothetical choices in which the acquisition and forfeiture conditions were created by manipulating initial attribute level reference states instead of ownership finally consistent with the experimental findings a field survey showed that relative to market prices owners of relatively hedonic cars value their vehicles more than do owners of relat

consumer side actions in a low carbon economy a dynamic cge analysis for spain abstract in recent decades the need to strengthen efforts to reduce ghg emissions to combat climate change has become a major global concern as reflected in the 2015 paris agreement and the eu climate strategy 2016 in this context eu countries are required to organize their contributions to environmental improvement through national strategies given the potential importance of demand side actions both directly and through their relationship with the productive system as well as the need for a dynamic evolution we assess the dynamic path and medium term environmental impact of certain consumer oriented measures using a dynamic computable general equilibrium cge model specifically we generate scenarios that follow spain s strategies and evaluate the dynamic impact of more efficient technologies on electricity consumption and the use of transport services both in terms of environmental ghg and sox and economic effects our results confirm the role of technology improvements in delivering positive results for the environment and the importance of economy wide rebound effects through a detailed study of energy uses as a result of efficiency improvements in household energy consumption our findings show that reductions in emissions per person are consistent with economic growth
