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

multivariate count data regression models with individual panel data from an on site sample the purpose of this paper is to consider the problem of controlling for on site sampling in the context of a system or panel of demand equations specifically in the context of recreation demand we are concerned with the situation in which survey respondents are asked to provide information not only about the actual trips to a specific site observed behavior but also their anticipated trips either under current conditions or given price and quality changes a multivariate poisson log normal mpln model and a seemingly unrelated negative binomial sunb model are used to jointly model the observed and contingent behavior data and to correct for on site sampling

government deficits the real interest rate and ldc debt on global crowding out abstract the paper uses a three regions model of global saving investment balance to present a global crowding out interpretation of present economic trends the model builds on data which point to a possible shortage of savings explosive growth of social expenditures structural public sector deficit in north and south changes of the age pyramid real wage rigidity in many industrial countries

sustainable consumption within a sustainable economy beyond green growth and green economies abstract in 1992 one unambiguous result of the unced conference was the need for changing consumption and production patterns with affluent countries taking the lead 20 years later at the 2012 uncsd little is left over and instead the green economy has been the theme pursued by the oecd the eu and other countries so the question needs to be answered if this is finally an attempt to put into practice what was promised 20 years ago or another diversion from what needs to be accomplished sustainable development is still a convincing concept if the original definition is taken avoiding the confusion caused by partisan interests reinterpreting the concept focussing on human needs fulfilment and respecting environmental limits it can still guide strong sustainable consumption green economy green growth on the other hand is a new terminology for what is known since 40 years as ecological modernisation it is indeed overdue but with its focus on efficiency and innovation it cannot guarantee to fulfil the brundtland sustainability criteria a factor analysis based on the i p a t formula demonstrates how optimistic the assumptions regarding future technologies must be to support the green growth concept consequently the authors pledge for a pragmatic risk avoiding approach by slimming the physical size of the economy this requires strong sustainable consumption including production as resource consumption which in turn requires a change of the societies institutional settings formal and informal mechanisms and orientations finally some elements of a strategy towards this end are pointed out with special emphasis on the role of non governmental organisations ngos through networking and advocacy they can both stimulate bottom up action and mobilise the pressure necessary for the institutional changes which are needed to mainstream strong sustainable consumption

population growth and savings in ldcs a survey article both population growth and savings have traditionally taken a certain place of pride among models of growth and development the purpose of this paper is to examine the literature concerning the hypothesis that the savings rate itself is a function of the population growth rate and this effect exacerbates the negative effect of population on economic growth the evidence is examined from three perspectives i macroeconomic effects of variations in the age structure of the population ii choice theoretic models of family decision making particularly the joint determination of fertility decisions and savings decisions and iii market level interactions of variables which determine individual decisions the paper concludes that both population growth and savings rates are inextricably tied up in the process of economic development there are many ways in which the two variables may interact but no generalizations can be safely made across countries

population pressures saving and investment in the third world some puzzles for over 25 years economists and population specialists have generally embraced the plausible notion that rapid rates of population growth exert a quantitatively significant adverse impact on the pace of economic growth through the effects of age dependency capital shallowing and investment diversion however empirical research has not sustained these hypotheses individually or collectively one general factor appears to account for this variance between theory and facts the tendency to develop analyses with simplifying assumptions that are not then subjected to adequate empirical tests at its most fundamental level economics is about making choices in the face of scarcity in the literature relating population growth savings and investment and modeling of choices has been amazingly narrow indeed almost a economic at the household level population pressures are usually modeled by engineering like fixed coefficient formulae in contrast trade offs between quantities or qualities of consumption are seldom admitted parents work force behavior is usually taken to be uninfluenced by family size and children are typically assumed to contribute nothing productively similarly at the government level population pressures are modeled to show population sensitive expenditures taking priority and crowding out more productive spending in reality governments respond with more flexibility than the models suggest and some of the population sensitive expenditures may be growth enhancing more elaborate analyses reveal 2nd order effects economizing on scarce resources and an expansion in supply

testing the validity of contingent behavior trip responses while a number of validity tests exist for contingent valuation data to date there are very few literature examples for contingent behavior cb data the objective of this study is to test the validity of cb trip data for different levels of rock climbing access using data from surveys implemented before and after a policy restricting recreational access was imposed results from generalized negative binomial and seemingly unrelated poisson regression models show significant sensitivity to scope and suggest that cb data may be a valuable supplement to revealed preference data when policy proposals are outside the range of historical conditions copyright 2002 oxford university press

a panel travel cost model accounting for endogenous stratification and truncation a latent class approach in this paper we develop a panel data negative binomial count model that corrects for endogenous stratification and truncation we also incorporate a latent class structure into our panel specification which assumes that the observations are drawn from a finite number of segments where the distributions differ in the intercept and the coefficients of the explanatory variables the paper argues that count data panel models corrected for on site sampling may still be inadequate and potentially misleading if the population of interest is heterogeneous with respect to the impact of the chosen explanatory variables jel q51 q57

investigation of stated and revealed preferences for an elk hunting raffle the charter forest experiment at the valles caldera national preserve vcnp in new mexico provides land managers policymakers and researchers a unique opportunity to examine an alternative public land management institution the vcnp mature bull elk permit lottery has been the largest revenue generating recreation program at the preserve since the program s inception in 2002 this paper uses stated and revealed preference ticket purchase data collected through an online survey to estimate a set of ticket demand equations for the purpose of assessing revenue generation access and the willingness to donate to this program

green growth or degrowth assessing the normative justifications for environmental sustainability and economic growth through critical social theory abstract scientists agree that changes in the organization of human society and economy are needed to stop the degradation of the natural environment the most commonly proposed solution green growth has been increasingly criticized but the offered alternative of degrowth has remained a marginal undertaking in academia and in practice this article further develops the argument for degrowth the article conducts a comparative analysis of the normative foundations of green growth and degrowth using frameworks from critical social theory the analysis shows that green growth and degrowth work toward different normative ideals that are justified in different ways the analysis shows that degrowth has a stronger normative justification than green growth and therefore should be preferred the article contributes to the debate about green growth and degrowth by establishing normative grounds for focusing efforts for environmental sustainability on degrowth rather than green growth

fiscal spending and green economic growth evidence from china abstract the green economy is considered as an efficient way for sustainability but the connection between fiscal spending and green economic growth has not been systematically explained this paper attempts to fill this research gap based on the panel data of 282 prefecture level cities from 2005 to 2016 we first construct the green economic growth index by using the non radial direction distance function then by employing the system gmm estimation we further evaluate the effect of fiscal education spending and r d spending on green economic growth finally we explore the potential mechanism and discuss our findings we obtain the following conclusions 1 the green economic growth index fluctuated in the study period we attribute it to the political tournament of local governments 2 the system gmm estimation results confirm the existence of composition effect and technique effect in the full sample but the sub sample analysis suggests that there is a heterogeneous effect in different areas with different resources abundant degree 3 mechanism analysis illustrates that fiscal r d spending and education spending foster the green economic growth through technological activities and human capital intensive activities respectively but they exhibit distinct roles in different areas based on these findings we propose some targeted policy suggestions for promoting green economic growth

policy evaluation with combined actual and contingent response data the city of marietta georgia experimentally switched from flat fee financing to volume based pricing for its trash services in january 1994 both before and during the experiment detailed data on individuals observed responses to the actual introduction and contingent behavioral responses to a hypothetical introduction of volume based pricing were collected this study applies these data and investigates the methodology of collecting contingent behavior data and their use in policy analysis in particular this study empirically evaluates the effect of experience with the policy on responses to contingent behavior questions and tests for potential bias in the contingent behavior data

combining contingent valuation and travel cost data for the valuation of non market goods the travel cost method tcm has long been used to infer the economic value of nonmarket resources and public goods more recently contingent valuation cvm survey methods have gained popularity for eliciting these values here cvm survey responses are combined with tcm data on actual market behavior to estimate jointly both the parameters of the underlying utility function and its corresponding ordinary demand function this is a prototypical empirical example of a new modeling strategy variants of which should prove useful in many applications especially where reliance on a single valuation method is undesirable

estimating the demand for a new technology bt cotton and insecticide policies this article examines the potential demand for bt cotton in the southeast from information gathered in the first year of commercialization we combine revealed preference rp data on adoption of bt cotton varieties with stated preference sp data on willingness to adopt to estimate demand using a double bounded maximum likelihood procedure using estimated demand equations we simulate the costs of reducing conventional insecticide applications through subsidization of bt cotton results indicate that reducing cotton insecticide applications by 40 in the southeast would require a 21 acre subsidy with total annual program costs between 53 million and 60 million

the individual travel cost method with consumer specific values of travel time savings the treatment of the opportunity cost of travel time in travel cost models has been an area of research interest for many decades our analysis develops a methodology to combine the travel distance and travel time data with respondent specific estimates of the value of travel time savings vtts the individual vtts are elicited with the use of discrete choice stated preference methods the travel time valuation procedure is integrated into the travel cost valuation exercise to create a two equation structural model of site valuation since the travel time equation of the structural model incorporates individual preference heterogeneity the full structure model provides a travel cost site demand model based upon individualized values of time the methodology is illustrated in a study of recreational birdwatching more specifically visits to a stork village in poland we show that the usual practice of basing respondents vtts on 1 3 of their wage rate is largely unfounded and propose alternatives including a separate component of the travel cost survey aimed at valuation of respondents vtts or as a second best asking if they wish if their journey was shorter and for those who do use full hourly wage as an indicator of their vtts

degrowth from theory to practice abstract the collection of articles reviewed in this editorial presents an eclectic sample of the best contributions from the second international conference on degrowth exemplifying recent debates in the field and touching on different aspects of the multi dimensional transition at stake moving beyond theory and the construction of the degrowth proposal the articles in this special issue look at particular applications new methodologies and fresh policy options for example social enterprises are evaluated as primer candidates for a sustainable degrowth economy in the north lessons are also drawn from very different parts of the world such as cuba s experience with an oil and commodity shock to which it adapted through the introduction of ecological labour intensive agriculture in urban regions this special issue approaches from a degrowth perspective important sectoral issues in agriculture resource consumption and water the unsustainable fuel dependence of the spanish agrarian sector where the energy input for the production process is six times higher than the energy contained in finished food products is analysed in the context of the industrialization of food production rather than efficiency sufficiency in consumption is proposed as an organising societal principle and a call is made for stronger ngo action and coalition building in the direction of absolute rather than relative consumption reduction the obstacles to sufficiency policies are illustrated with a case study on water in the city of barcelona where a growth discourse is still dominant and a source of a technological and institutional deadlock against softer decentralized and more participatory forms of water management finally many of the contributions in this issue focus on work the policy option of a job guarantee scheme is examined as a tool to decouple jobs from economic growth and fiscal policy by bringing them to the realm of political rights this is complemented by a discussion of the social benefits of an amateur economy through work sharing and a socially beneficial reduction in labour productivity original data from barcelona analysed for this special issue shows that household activities an essential component of a more amateur economy have a much lower intensity of energy use than the paid sector delivery of equivalent services especially government and privatized caring services interesting research questions are identified concerning work under a degrowth trajectory not least whether reducing paid work will be possible in an energy scarce future put together the diverse contributions of this issue show that there is a vibrant and fertile degrowth research agenda with a range of open questions to which the community of this journal has much to offer

re evaluating the income elasticity of the property tax base an important research issue relating to the property tax is its income elasticity income elasticities provide a potentially cost effective means to forecast local government revenues and in policy analysis they are used to judge the tax s behavior over business cycles its stability and capacity to generate necessary growth in revenues its adequacy while previous income elasticity estimates have been derived from simple log linear models this paper focuses on the residential component of the property tax base and develops and estimates a nonlinear structural model of residential property valuation in further contrast to previous studies which have relied on national or state

the nature of the savings function in developing countries a survey of the theoretical and empirical literature the savings rate marginal or average is regarded as a key performance indicator by development economists and foreign aid practitioners admonish their clients to increase their savings ratio as a primary condition for achieving a satisfactory rate of economic growth however not only have questions been raised regarding the significance of the savings effort as an independent determinant of economic progress but the formulation of policies designed to increase the savings propensity has suffered from a dearth of knowledge regarding the nature of the savings function in developing countries a number of alternative savings hypotheses derived mainly from the literature relating to developed economies have been advanced but the paucity of reliable data has made it difficult to test these hypotheses and obtain results which warrant a reasonable degree of confidence the purpose of this article is a to review the theoretical and empirical literature on the savings function in developing countries b to assess critically the findings with respect to the major hypotheses and c to summarize the state of our knowledge on this important topic we shall begin with a brief review of the nature of the data on savings in developing countries with which economic analysts must work

consumption benefits of national hockey league game trips estimated from revealed and stated preference demand data this paper examines the demand for hockey game trips among metropolitan and nonmetropolitan residents of alberta canada using data on both revealed and stated preference game trip behavior from a telephone survey conducted throughout alberta we estimate the effect of ticket prices team quality arena amenities and capacity on the latent demand for national hockey league hockey games we nd that lower ticket prices higher team quality and additional capacity encourage attendance in the status quo scenario consumer surplus per game is 50 for those who had attended hockey games and about 50 less for those who had not attended games exploiting the stated preference data we develop a number of other consumer surplus estimates we also include travel costs in the estimation of the demand function and estimate the full value of the game trip considering both ticket prices and travel costs sold out arenas in calgary and edmonton generate annual consumption bene ts of 40 and 35 million when only ticket prices are used to calculate consumer surplus i e excluding travel costs considering the full price consumer surplus for the calgary flames of 103 per game trip the annual consumption bene ts may be as high as 82 million jel r22 l83 d61

a semi parametric estimator for revealed and stated preference data an application to recreational beach visitation abstract we present a semi parametric approach for jointly estimating revealed and stated preference recreation demand models the discrete factor method dfm allows for correlation across demand equations and incorporates unobserved heterogeneity our model is a generalized negative binomial with random effects the random effect is composed of a discrete representation of unobserved heterogeneity and a factor loading that translates the heterogeneity measure into a demand effect our empirical application is to beach recreation demand in north carolina statistical evidence supports our dfm specification which imposes less restriction on model dispersion and incorporates unobserved heterogeneity in a flexible manner elasticity estimates are smaller than those derived from models with parametric specifications for unobserved heterogeneity and welfare estimates are slightly larger and less precise while parametric models clearly dominate if the specification of unobserved heterogeneity is correct the semi parametric dfm provides a flexible alternative in cases where mis specification is a potential problem

convergent validity and the time consistency of preferences evidence from the iowa lakes recreation demand project we examine the consistency of preferences over time and as implied by revealed versus stated preference contingent behavior data studies in this area are typically based upon a single site and focus on consumer response to changes in travel cost or site access we use data from the iowa lakes project which provides information on usage patterns over several years and for 132 lakes along with detailed water quality data this allows us to test for convergence in how individuals respond to changing site characteristics as well as the consistency of preferences over time and between actual versus contingent trips

population dependency rates and savings rates stability of estimates challenging the notion that increasing dependency rates lower the national savings rate in developing countries this study explored the stability of dependency effects over time while holding constant the sample of countries in an attempt to examine the link between the two rates specifically researchers estimated savings rate equations for 1975 1980 and 1985 and looked at regionally differential effects of dependency ratios on the national savings rate these equations were estimated separately for each year for developing countries in africa latin america and asia the model structure proved generally unstable for the years between 1975 and 1980 and for countries in africa and latin america between 1975 and 1985 the savings model structure was significantly different across each region for each of the 3 years examined as population variables on savings rates varied among developing countries depending on their geographical location results concurred with findings from earlier research suggesting the impact country composition included in the estimation has upon study results broadly speaking however dependency rate effects did not significantly change over time no strong evidence was produced to support generalizations that increasing dependency rates lower the national savings rate data sources and savings equations and variables are discussed in the report

modelling recreation demand using choice experiments climbing in scotland this paper is concerned with the use of thechoice experiment method for modelling thedemand for recreation using the example ofrock climbing in scotland we begin byoutlining the method itself including itstheoretical and econometric underpinnings datacollection procedures are then outlined wepresent results from both nested and non nestedmodels and report some tests for theimplications of choice complexity andrationality finally we compare our resultswith a revealed preference data model based onthe same sample of climbers

the saving of the elderly in micro and macro data examination of household micro data on the elderly has generally concluded that they do not dissave significantly whereas estimates using aggregate macro data have shown that the presence of a large elderly population leads to a lower saving rate this paper shows that if interactions between generations are important one would not expect these estimates to be the same the paper presents new evidence that bequests are plausibly the source of this discrepancy examination of data from young households that have received or expect bequests confirms that bequests are indeed an important factor determining the saving of the young

omitted cross price variable biases in the linear travel cost model correcting common misperceptions the essence of the travel cost method is that the combination of the number of visits to a site and the round trip travel costs for each recreationist traces out a demand relationship since the geographic location of the recreationist s residence exerts a kind of experimental control which forces the more distant consumer to bear higher travel and related costs these travel costs are used as proxies for prices in estimating demand for the site s services clawson 1959 has presented the two step method for valuing a single site s services however it has been pointed out in the literature that single and isolated recreation sites very rarely exist and the failure to include prices for alternative sites in the demand equation leads to biased estimates for the value of the resource under consideration the literature contains some misconceptions about the direction of the bias consider quotations from two frequently cited studies

the demand for solid waste disposal in this paper we estimate the elasticity of demand for landfill disposal of municipal solid waste using data from the portland oregon metropolitan area efficiency losses associated with deviations from marginal cost pricing of disposal services are then derived the efficiency losses of small deviations from long run marginal disposal costs are not large however many municipalities finance solid waste services from general tax revenues in which case waste generators effectively face zero marginal costs here the efficiency losses are much larger indicating that communities would benefit from introducing volume or weight based pricing

a note on the welfare effects of omitting substitute prices and qualities from travel cost models the bias to welfare estimates from omitting substitute prices or qualities in travel cost models is examined the presence of bias depends on whether single or multiple site changes are examined and the degree of correlation between the omitted and included prices for a multiple site price or quality change even when omitted price is uncorrelated with included price welfare estimates may be biased alternatively if omitted price is perfectly correlated the welfare measure may not be biased the presence of the bias depends equally on both the degree of correlation and whether a single or multiple change occurs this abstract was borrowed from another version of this item

in defence of degrowth abstract this article defends the proposal of sustainable degrowth a starting premise is that resource and co2 limits render further growth of the economy unsustainable if degrowth is inevitable the question is how it can become socially sustainable i e a prosperous and stable rather than a catastrophic descent pricing mechanisms alone are unlikely to secure smooth adaptation a full ensemble of environmental and redistributive policies is required including among others policies for a basic income reduction of working hours environmental and consumption taxes and controls on advertising policies like these that threaten to harm the economy are less and less likely to be implemented within existing market economies whose basic institutions financial property political and redistributive depend on and mandate continuous economic growth an intertwined cultural and political change is needed that will embrace degrowth as a positive social development and reform those institutions that make growth an imperative sustainable degrowth is therefore not just a structuring concept it is a radical political project that offers a new story and a rallying slogan for a social coalition built around the aspiration to construct a society that lives better with less

augmenting travel cost models with contingent behavior data this paper proposes contingent behavior survey questions as a valuable supplement to observed data in travel cost models of non market demand for recreational resources a set of observed and contingent behavior results for each survey respondent allows the researcher to control for individual heterogeneity by taking advantage of panel data methods when exploring the nature of respondent demands the contingent scenarios also provide opportunities to a test for differences between observed and contingent preferences and or b assess likely demands under conditionsbeyond the domain of observed variation in costs or resource attributes most importantly contingent scenarios allow the researcher to imposeexogenously varying travel costs exogenous imposition of travel costs together with panel methods reduces the omitted variables bias that plagues observed data travel cost models of recreational demand using a convenience sample of data for illustrative purposes we show how to estimate the demand for recreational angling by combining observed and contingent behavior data we begin with simple naive pooled poisson models and progress to more theoretically appropriate fixed effects panel poisson specifications

choices without prices without apologies valuing is usually regarded as a process of compressing information about attributes into a single metric armed with this reduced form of compact information the consumer can consider a particular object with a particular price attached or implied and make an informed decision but the process of valuing is less straightforward than we ordinarily suppose when environmental goods and services become the object of information compaction it is possible that important information is lost we comment on the choice problem germane to environmental goods and services and challenge the presumption that environmental choices made without explicit pricing are inferior to those in which hypothetical valuation studies are undertaken

strong sustainable consumption governance precondition for a degrowth path this paper aims to link two debates and literatures at the cutting edge of sustainable development research and governance sustainable consumption and degrowth interestingly these literatures have only recently started to exchange and integrate insights despite their similar interest in the fundamental systemic challenges to sustainable development the paper argues that this lack of connection is due to a predominance of perspectives in sustainable consumption governance that focus almost exclusively on questions of efficiency gains this weak sustainable consumption governance however is not able to address the challenges to sustainable development arising from overconsumption in general or the rebound effect and distributive issues in particular in contrast a strong sustainable consumption perspective provides a basis for a promising inquiry into the linkages between consumption and sustainable development as well as a fruitful exchange with degrowth specifically it allows the delineation of relevant insights on the role of values in governance obstacles to political reform and promising political strategies for the degrowth debate and literature

comparative analysis of non market valuation techniques for the eduardo avaroa reserve bolivia abstract ecological tourism has held up as a potentially important development alternative in relatively undeveloped regions and countries however tourism is a highly vulnerable activity where tourists display voluntary and discretionary behavior while tourism can serve as an income generating activity for the region uncontrolled tourism that is developed without consideration of the environmental impact can adversely affect the natural areas determining what to charge tourists to view a natural area is difficult since demand elasticities are not readily available from observable transactions in order to better gauge the value tourists place on the reserve and their sensitivity to changes in the costs of visiting eduardo avaroa non market valuation provides several valuable tools here we test the convergent validity between two popular non market valuation alternatives the contingent valuation method and the contingent behavior method tourists to the eduardo avaroa reserve in bolivia were asked their willingness to pay in visitor days or in dollars due to an improvement in tourism services at the reserve our models show that the traditionally important variables predict willingness to pay for improved services for the contingent behavior contingent valuation and the pooled model however we find statistically and empirically meaningful distinctions in the estimates derived from the two methods comparisons of the implications of adopting the entrance fee recommendations from the two non market valuation techniques are made based on the revenues predicted to accrue to eduardo avaroa reserve if park management techniques were improved this research highlights the challenges in using non market valuation techniques for policy formation particularly in a developing country setting

combining revealed and stated preference data to estimate the nonmarket value of ecological services an assessment of the state of the science this paper reviews the marketing transportation and environmental economics literature on the joint estimation of revealed preference rp and stated preference sp data the rp and sp approaches are first described with a focus on the strengths and weaknesses of each recognizing these strengths and weaknesses the potential gains from combining data are described a classification system for combined data that emphasizes the type of data combination and the econometric models used is proposed a methodological review of the literature is pursued based on this classification system examples from the environmental economics literature are highlighted a discussion of the advantages and disadvantages of each type of jointly estimated model is then presented suggestions for future research in particular opportunities for application of these models to environmental quality valuation are presented

dynamic savings behaviour in an oil dependent economy abstract this paper tests for the influence of income demography terms of trade export orientation and real interest rates on savings behaviour in trinidad and tobago within an error correction formulation it finds evidence in favour of the error correction mechanism under which the savings rate varies procyclically in the short run but remains constant in the steady state in addition long run and short run significant effects are found for income real interest rates and export orientation demography is significant only in the long run while the terms of trade is not significant in either the short or long run

degrowth business framework implications for sustainable development abstract recent years have seen a revival in growth scepticism yet degrowth in relation to the macroeconomic level has received almost exclusive attention this resulted in a lack of literature on how post growth and specifically degrowth visions of economy could be implemented including from the perspective of firms and other organisations this paper focuses on degrowth literature and fields of knowledge which share a similar or sympathetic perspective regarding the undesirability of economic growth and desirability of living within planetary boundaries while pursuing wellbeing it then applies degrowth vision to firms and identifies potential elements of a business for a degrowth economy here referred to as a degrowth business these elements comprise a degrowth business framework the framework is centred around the following groups 1 environment 2 people and non humans and 3 deviation from profit maximisation imperative it aims to contribute to an emerging discussion on what firms should be like for a degrowth economy and society to be possible

degrowth taking stock and reviewing an emerging academic paradigm degrowth has evolved within a decade from an activist movement into a multi disciplinary academic paradigm however an overview taking stock of the peer refereed degrowth literature is yet missing here we review 91 articles that were published between 2006 and 2015 we find that the academic degrowth discourse occupies a small but expanding niche at the intersection of social and applied environmental sciences the discourse is shaped by authors from high income mainly mediterranean countries until 2012 articles largely constitute conceptual essays endorsed by normative claims more recently degrowth has branched out into modelling empirical assessments and the study of concrete implementations authors tend to agree in that economic growth cannot be sustained ad infinitum on a resource constraint planet and that degrowth requires far reaching societal change whether degrowth should be considered as a collectively consented choice or an environmentally imposed inevitability constitutes a major debate among degrowth thinkers we argue that the academic discourse could benefit from rigid hypotheses testing through input output modelling material flow analysis life cycle assessments or social surveys by analyzing the potentials for non market value creation and identifying concrete well being benefits the degrowth discourse could receive wider public support and contribute to a paradigmatic change in the social sciences

mitigating hypothetical bias in stated preference data evidence from sports tourism one of the major criticisms of stated preference data is hypothetical bias using a unique dataset of both stated and actual behavior we test for hypothetical bias of stated preference survey responses we consider whether respondents tend to overstate their participatory sporting event behavior ex ante when compared to their actual behavior at different registration fees we find that stated behavior accurately predicts actual behavior at a middle level of respondent certainty overpredicts actual behavior at a lower level of certainty and underpredicts behavior at a higher level of certainty this result suggests that respondent uncertainty corrections can be used to mitigate hypothetical bias and stated preference data can be used to better understand actual behavior in situations where no data exist jel l83 q51 z2

mass customization a method for market segmentation and choice menu design abstract this paper proposes a method for designing choice menus for mass customization mc the method is based on the analysis of stated preferences sp on product or service attributes obtained through panel studies the method is first presented and then illustrated with a real world case application in a natural gas ng distribution company the case application indicated the method was able to elicit stated preferences on a broad range of attributes enabling the design of choice menus of different sizes and content for alternative customer segments thus balancing the trade off between flexibility and complexity that is at the core of choice menu design

a note on long term determinants of the private savings ratio abstract this note presents some new evidence about cross country differences in the private savings ratios opposite to claims forcefully proposed e g by feldstein social security benefit variables do not contribute to explain these differences instead our results suggest that variables describing degree of development of monetary systems perform strikingly better according to our estimation results there is a clear positive relationship between these variables and the private savings ratio

adopt a hypothetical pup a count data approach to the valuation of wildlife the willingness to pay wtp for a coyote conservation program is estimated using a novel payment vehicle based on how many problem coyotes respondents would be willing to sponsor for a year this hypothetical scenario mimics an increasingly popular type of actual market data from a phone survey conducted in prince edward island are analyzed using count data models that consider different processes explaining zero responses and the level of positive responses this is particularly important in the case of coyotes often regarded as an economic bad estimates of wtp per coyote per year around 18 22 and annual wtp per contributor of about 46 57 are obtained

sequencing and nesting in contingent valuation surveys abstract the term embedding is ill defined and has been applied to distinct phenomena some predicted by economic theory and others not this paper lays out a theoretical framework for looking at these phenomena and provides a set of well defined terms included is a discussion of survey design problems which may induce spurious evidence in favor of the hypothesis that respondents are insensitive to the scope of the good being valued an empirical example of the component sensitivity is provided this test rejects the hypothesis that respondents are insensitive to the scope of the good being valued

capital accumulation income distribution and endogenous fertility in an overlapping generations general equilibrium model abstract this paper studies the intertemporal relationships among population growth income distribution inter generational social mobility skill composition of the labor force and household income in an overlapping generations general equilibrium model that aggregates household decisions regarding fertility savings and investment in human capital of children it shows that as a consequence of endogenous fertility the equilibrium path attains steady state from the second generation income tax transfer child taxation and social security taxation policies that can be devised to affect these variables are also analyzed the model provides a structural explanation for the inverse household income child quantity and negative child quality quantity relationships that are observed in developing countries it also shows that group interests may hinder the emergence of perfect capital markets with private initiatives

an extension of omitted cross price variable biases in the linear travel cost model correcting common misperceptions caulkins bishop and bouwes cbb 1985 raise an important issue concerning the conventional presumption of positive bias in consumer surplus when alternative sites are ignored in the travel cost method treatment of site value dwyer kelly and bowes 1977 they analyze a significant geographic dispersion phenomenon which can cause either negative or positive bias in travel cost model tcm estimates of site value when travel costs to alternative sites are omitted however the derivation of specification bias in the tcm which they provide is incomplete and could lead to generalizations which are erroneous cbb use the well known specification bias analysis to discuss the possible effects of ignoring alternative recreation sites in the tcm demand analysis given the estimated linear regression equation

valuing water level changes in reservoirs using two stated preference approaches an exploration of validity the combination of travel cost tcm and contingent behaviour cb methods is a relatively new research avenue in the recreational valuation community contrary to simple tcm applications tcm cb facilitates the ex ante valuation of marginal welfare effects resulting from environmental quality or quantity changes similar to the contingent valuation method cv even though tcm cb is highly policy relevant i e to inform changes in management regimes at recreational sites the validity of estimates has hardly received any attention and little is known about the performance of tcm cb compared to cv in this paper tcm cb and cv are explored with respect to several validity tests in a case study on the recreational effects of water level changes in a reservoir overall the findings reveal that tcm cb and cv perform equally well in terms of theoretical validity but that the marginal recreational value varies significantly between the two methods we also observe that both methods face similar internal difficulties with respect to the stability of values when the order of a set of valuation questions is changed

the economics of household solid waste generation and disposal abstract we develop a household production model of waste management that explicitly incorporates many of the technical and behavioral elements germane to current regulatory and non regulatory solid waste policy initiatives examination of first order conditions shows the interaction among household preferences these production options and external prices and fees a simplified simulation of our model illustrates these relationships showing that household response elasticities can vary widely over common price ranges and that relatively large household welfare gains may be obtained by adopting curbside recycling and unit pricing programs

consistency in mixed demand systems contingent valuation and travel cost data in contrast to previous literature we propose a consistency test that does not impose any particular common functional form for the preference structure underlying the travel cost tc and contingent valuation cv models we derive testable consistency conditions between tc and cv data in the context of mixed demand systems when valuing changes in environmental quality these conditions are a subset of the rationality conditions the proposed consistency tests are implemented combining tc and cv data the empirical results show that it is possible to combine stated tc and cv but not revealed tc and cv data

using count data models in travel cost analysis with aggregate data estimators of recreational demand models frequently use continuous functional forms such as ordinary least squares ols on log transformed variables e g ziemer musser and hill however the nature of trip demand introduces complicating factors first trips occur in nonnegative quantities failure to control for this censoring will lead to biased estimation second because trips are available only in integer quantities the usual demand models which correlate marginal quantity with marginal price may be inapplicable in light of these factors a natural alternative is to use statistical models that explicitly recognize the count nature of trip demand several recent papers e g shaw smith grogger and carson creel and loomis have applied count models to the travel cost model these works largely have focused on truncated data sets based on choice based samples in this study the focus is on the older problem where zero demanders are included in particular the application of several robust estimators of count models to aggregated data will be considered the poisson distribution forms the foundation for the count models examined in this study although the poisson is a convenient distribution to work with it imposes some stringent constraints on the demand distribution in particular the poisson distribution assumes the variance of trip demand is equal to the expected value of trip demand to loosen these constraints a generalization of the poisson the negative binomial is discussed robust estimation procedures that permit further loosening of a priori assumptions are then reviewed permit data from the boundary waters canoe area are used to examine the effects of these count models on consumer surplus estimates and on coefficient variability

the effects of variable omission in the travel cost technique the travel cost technique is probably the most widely used method for estimating outdoor recreation demand functions consequently problems of specification have attracted much attention specification errors due to the omission of travel time and congestion effects have received the most recent attention with the consensus being that the travel cost technique underestimates the true value of recreational resources if these variables are omitted gum and martin 1975 wetzel 1977 mcconnell and duff 1976 yet the effect of variable omission is likely to vary depending upon the type of activity the existence of substitutes and related factors for this reason we reexamine from both an empirical and theoretical perspective the magnitude and nature of potential specification errors due to variable omission

willingness to pay for quality improvements should revealed and stated preference data be combined abstract in this article we propose theoretically consistent welfare measurement of use and nonuse values for an improvement in environmental quality with revealed and stated preference data an analytical model based on the comparative static analysis of the variation function that describes the relationship between recreation demand and dichotomous choice contingent valuation models is estimated our results show that revealed and stated data should not be combined under the same assumed preference structure unless the two decisions imply the same change in behavior induced by the quality change in addition our results indicate scope effects in willingness to pay measures estimated with stated preference data

a new approach to random utility modeling using the dirichlet multinomial distribution in this paper we introduce a new econometricapproach to analyzing recreational site choicedata the dirichlet multinomial model thismodel which nests the standard conditionalmultinomial logit model can accommodateover dispersed data and may provide moreefficient estimators of coefficients andconsequent welfare measures than the standardconditional logit model which is so widelyused in the random utility model approach torecreation demand we illustrate thisdirichlet approach using a data set of rockclimbers in scotland and study the impacts onper trip consumers surplus of alternativemanagement strategies for popular rock climbingsites results show that the dirichletmultinomial approach produces coefficient andwelfare estimates having smaller samplingvariability in this case we also compareclassical welfare measures with their posteriorequivalents which allow for welfare changes tobe dis aggregated

assessing the degrowth discourse a review and analysis of academic degrowth policy proposals abstract debates on ecological and social limits to economic growth and new ways to deal with resource scarcity without compromising human well being have re emerged in the last few years central to many of these is a call for a degrowth approach in this paper a framework is developed to support a systematic analysis of degrowth in the academic literature this article attempts to present a clearer notion of what the academic degrowth literature explores by identifying organising and analysing a set of proposals for action retrieved from a selection of articles the framework is applied to classify proposals according to their alignment to ecological economics policy objectives sustainable scale fair distribution and efficient allocation type of approach top down versus bottom up and geographical focus local national or international a total of 128 peer reviewed articles focused on degrowth were reviewed and 54 that include proposals for action were analysed the proposals identified align with three broad goals 1 reduce the environmental impact of human activities 2 redistribute income and wealth both within and between countries and 3 promote the transition from a materialistic to a convivial and participatory society the findings indicate that the majority of degrowth proposals are national top down approaches focusing on government as a major driver of change rather than local bottom up approaches as advocated by many degrowth proponents the most emphasised aspects in the degrowth literature are related to social equity closely followed by environmental sustainability topics such as population growth and the implications of degrowth for developing nations are largely neglected and represent an important area for future research moreover there is a need for a deeper analysis of how degrowth proposals would act in combination

the shallow or the deep ecological economics movement ecological economics and its policy recommendations have become overwhelmed by economic valuation shadow pricing sustainability measures and squeezing nature into the commodity boxes of goods services and capital in order to make it part of mainstream economic financial and banking discourses there are deeper concerns which touch upon the understanding of humanity in its various social psychological political and ethical facets the relationship with nature proposed by the ecological economics movement has the potential to be far reaching however this is not the picture portrayed by surveying the amassed body of articles from this journal or by many of those claiming affiliation a shallow movement allied to a business as usual politics and economy has become dominant and imposes its preoccupation with mainstream economic concepts and values if instead ecological economists choose a path deep into the world of interdisciplinary endeavour they will need to be prepared to transform themselves and society the implications go far beyond the pragmatic use of magic numbers to convince politicians and the public that ecology still has something relevant to say in the 21st century author s abstract

convergent validity of revealed and stated recreation behavior with quality change a comparison of multiple and single site demands we consider the convergent validity of several demand models using beach recreation data two models employ multiple site data a count data demand system model and the kuhn tucker demand system model we explore the role of existing variation in beach width in explaining trip choices and analyze a hypothetical 100 foot increase in beach width we compare these models to a single equation model where we jointly estimate revealed and stated preference trip data and focus on a hypothetical scenario considering a 100 foot increase in beach width in each case we develop estimates of the change in beach visits and the welfare impacts from the increase in width the trip change estimates from two of the three models are similar and convergent valid though the willingness to pay estimates differ in magnitude

sociopolitical instability and the behavior of savings in less developed countries the paper argues for the introduction of sociopolitical instability as a factor in explaining saving behavior it also provides empirical evidence in regard to the quantitative and qualitative relationship between these two variables the empirical results point towards an inverse relationship between sociopolitical instability and savings our estimates are based on a sample of 7 observations from 60 countries a new pooling procedure is used to address the problems of autocorrelation and heteroskedasticity

a difficulty with the travel cost method instead of observable prices of recreational visits travel cost method tcm re searchers are obliged to substitute researcher assigned visitation cost estimates i argue that visitation costs are inherently subjective but are ordinally measurable so long as the cost in creases with distance travelled it follows that traditional tcm yields only ordinally measur able welfare estimates the household produc tion function formulation of tcm resolves this problem only by imposing severe and un testable analytical restrictions tcm cannot serve as a stand alone technique for estimating recreation benefits rather it must be calibrated using information generated with fundamentally different methods jel q26

the response of aggregate production to fertility induced changes in population age distribution with a particular focus upon long term supply effects the authors explored the implications of different population age distributions for the productive capacity of an economy a multilevel aggregate production process was specified plausible values assigned to its parameters and steady state solutions obtained under a range of alternative fertility assumptions the theoretical model was calibrated to conform with canadian data and published estimates of age sex substitution elasticities the study found productive capacity to be related to age distribution although the output effects exceed 8 regardless of the structure of the economy only when total fertility rate is less than 1 6 or well above 3 0 within the range of variation productive capacity and output per capita are lower for both younger and older populations altering the elasticity of substitution between different tasks has negligible effects upon the sensitivity of the economy to changes in age distribution altering the elasticity of substitution between different age sex groups for a given task has a markedly greater effect introducing either increasing or decreasing returns to scale has only a minor effect upon the sensitivity of the economy to changes in age distribution and marginal products are quite sensitive to changes in age distribution for both younger and older workers but far less sensitive for middle aged workers

savings rates and income distribution further evidence from ldcs a cross country test for the existence of kaldor effects in less developed countries is developed earlier attempts have been inconclusive and have led to a perception that the effect is unimportant it is argued that previous tests may have ben misspecified within a standard life cycle framework a savings rate function that also incorporates two distribution variables one involving measures of income inequalities across income classes and the other a broad measure of inequalities among sectors was specified and estimated the results indicate that regardless of the inequality measure employed some sort of kaldor effect may be at work this suggests that the traditional conflect between growth and equity warrants continued investigation

estimating the wetland rental fee a case study involving a taiwan wetland wetlands provide many functions that are both economic and recreational and are valuable in terms of their ecological diversity while at the same time being nonmarket value products the purpose of this study is to estimate the optimal wetland rental through estimations of both the demand and supply functions in relation to wetland the wetland supply function is directly estimated based on the data provided by the owners of the wetland while the estimation of the wetland input demand function involves using the bootstrapping and contingent visitation approaches such estimation approaches could also be applied to other nonmarket value products that give rise to environmental externalities the estimation of rental fee could provide a long term leasing contract that gives the landlord with a particular rent to lease their lands to support a wetland eco tourism park to maintain wetland for substantial management several environmental management policy implications are also addressed
