integrating methods for ecosystem service assessment and valuation mixed methods or mixed messages a mixed method approach was used to assess and value the ecosystem services derived from the dogger bank an extensive shallow sandbank in the southern north sea three parallel studies were undertaken that 1 identified and quantified where possible how indicators for ecosystem service provision may change according to two future scenarios 2 assessed members of the public s willingness to pay for improvements to a small number of ecosystem services as a consequence of a hypothetical management plan and 3 facilitated a process of deliberation that allowed members of the public to explore the uses of the dogger bank and the conflicts and dilemmas involved in its management each of these studies was designed to answer different and specific research questions and therefore contributes different insights about the ecosystem services delivered by the dogger bank this paper explores what can be gained by bringing these findings together post hoc and the extent to which the different methods are complementary findings suggest that mixed method research brings more understanding than can be gained from the individual approaches alone nevertheless the choice of methods used and how these methods are implemented strongly affects the results obtained

deliberative monetary valuation in search of a democratic and value plural approach to environmental policy the use of deliberative methods to assess environmental values in monetary terms has been motivated by the potential for small group discussion to help with preference formation and the inclusion of non economic values in this review two broad approaches are identified preference economisation and preference moralisation the former is analytical concentrates upon issues of poor respondent cognition and produces a narrow conception of value linked to utilitarianism the latter emphasises political legitimacy appeals to community values and tends to privilege arguments made in the public interest both approaches are shown to embrace forms of value convergence which undermine the prospects for value pluralism as a result exclusion and predefinition of values dominates current practice in order to maintain democratic credentials the importance attributed to monetary value needs to be left as an open question to be addressed as part of a process determining an agreement to pay to this end we identify a discourse based approach as a third way consistent with the democratic and value plural potential of deliberative monetary valuation

deliberative monetary valuation dmv issues in combining economic and political processes to value environmental change abstract this paper explores and contrasts the different social processes of valuation now appearing as economic means of valuing the environment monetary valuation via stated preference approaches has been criticised for assuming well formed and informed preferences and excluding a range of sustainability concerns such as rights fairness and equity deliberative monetary valuation dmv in small groups is a novel hybrid of economic and political approaches which raises the prospect of a transformative and moralising experience critics of standard contingent valuation approaches have advocated this as offering a way forward however there has been a lack of clarity as to the means of obtaining values the expected outcomes and their role moving to group settings of deliberation raises concepts of social willingness to pay and accept which are distinct from an aggregate of individual value although this does not seem to have been widely recognised a new classification of values is presented appropriate to the literature trying to merge economic and political processes values associated with the individual may be exchange values charitable contributions or fair prices while social values can be speculative expressive or arbitrated the use of dmv is shown to result in different values due to variations in the institutional setting and process of valuation

strike coordination and dismissal in uniform wage settings abstract we study a gift exchange game with 12 employees and one employer when the employer can offer individually differentiated wages in a setting without collective action we observe high levels of wages effort choices and total earnings when the employer is restricted to offering a uniform wage trust and reciprocity drop dramatically due to widespread shirking the stepwise introduction of two collective action mechanisms strike and coordination increases the employees share of the total earnings but does not mitigate the free riding problem adding employment risk to the collective action setup drives up wages reduces free riding and leads to higher total earnings however this increase in productivity is not sufficient to achieve the high levels of wages efforts and earnings that we observe with individually differentiated wages

how deliberation affects stated willingness to pay for mitigation of carbon dioxide emissions an experiment respondents reported willingness to pay wtp for mitigating carbon dioxide emissions after structured group discussion or without this deliberation deliberation did not affect mean or median wtp but it increased the number of issues respondents considered with some issues becoming more frequently considered and others less survey only respondents considered issues relevant for responding to a request for a charitable contribution group mode participants considered issues relevant for a public policy assessment findings suggest that ordinary citizens can offer valid input to environmental policy decisions but that framing effects in ordinary wtp surveys may prevent them from providing such input

understanding environmental policy preferences new evidence from brazil we examine the relationship between socio economic factors and public opinion on environmental policies in brazil drawing on a survey conducted in june 2012 there are few systematic studies of the determinants of environmental preferences in emerging economies and brazil is a particularly interesting case because of its democratic political system rapid economic growth and importance for the global environment in general we find that the brazilian public is highly supportive of environmental protection to explain variation in environmental preferences we focus on the effects of income and education many previous studies suggest that both should have positive effects but the empirical evidence is mixed indeed we find that income has no effect on environmental preferences however education is a strong predictor of environmental preferences while college education is not necessary for environmental awareness there is a large difference between brazilians with primary and secondary education for policy the findings imply that investment in secondary education can raise environmental awareness regardless of income levels

willingness to pay of committed citizens a field experiment in this paper we propose a behavioral approach to determine the extent to which the consumer citizen distinction affects interpretations of monetary values in stated preferences methods we perform a field experiment dealing with air pollution where some randomly selected subjects are given the opportunity to behave politically by signing a petition for environmental protection prior to stating their private preferences in a standard contingent valuation exercise we show that signing has the potential to influence respondents willingness to pay values results indicate that even market like situations are not immune to citizen behavior

the economic valuation of biodiversity as an abstract good abstract the notion of an economic valuation of biodiversity raises major philosophical and practical challenges especially due to the fact that biodiversity is an abstract good insights from political philosophy and philosophy of language can help to clarify the reliability and scope of the current economic methods that can be used for the purpose of valuing it the analogy with another abstract good justice indeed shows that thinking about abstract goods is a very specific exercise if they do not take account of this specificity applications of hedonic and contingent valuation methods can hardly claim to be relevant to value biodiversity rawls theory of justice provides for the conceptual tools to overcome this problem a reinterpretation based on the theory of counterfactuals allows generalizing this account of justice to outline a theory of thinking about abstract goods this new framework emphasizes the importance of the institutional context in determining the reliability of thinking about abstract goods it points toward substantial reforms of the methodology of economic valuation specifically it suggests reinterpreting valuation as a dynamic expressive process where initial steps aim at reinforcing the reliability of later steps through an institutional transformation and stabilization of preferences for abstract goods

valuing the non market benefits of wild goose conservation a comparison of interview and group based approaches wild geese graze on improved pastures and young cereal crops and hence can cause considerable damage to agriculture particularly in areas close to roosting sites this study uses contingent valuation cv to establish whether government compensation payments currently made to farmers represent value for money by estimating the value placed on goose conservation by the general public benefit estimates from a conventional interview approach are compared with a group based approach called the market stall ms this involves two 1 h meetings held 1 week apart and differs from conventional interviews in that participants are given more time to consider their preferences and to discuss their wtp question with other household members we argue that this type of group based approach to environmental valuation offers important advantages over individual interview approaches especially for unfamiliar and or complex environmental goods

new foundations for ecological economics abstract ecological economics has been repeatedly described as transdiciplinary and open to including everything from positivism to relativism i argue for a revision and rejection of this position in favour of realism and reasoned critique looking into the ontological presuppositions and considering an epistemology appropriate for ecological economics to meaningfully exist requires rejecting the form of methodological pluralism which has been advocated since the start of this journal this means being clear about the differences in our worldview or paradigm from others and being aware of the substantive failures of orthodox economics in addressing reality this paper argues for a fundamental review of the basis upon which ecological economics has been founded and in so doing seeks improved clarity as to the competing and complementary epistemologies and methodologies in part this requires establishing serious interdisciplinary research to replace superficial transdisciplinary rhetoric the argument places the future of ecological economics firmly amongst heterodox economic schools of thought and in ideological opposition to those supporting the existing institutional structures perpetuating a false reality of the world s social environmental and economic systems and their operation

capturing the complexity of biodiversity a critical review of economic valuation studies of biological diversity biodiversity is a highly complex and abstract ecological concept even though it is not one physical entity it influences human well being in multiple ways mostly indirectly while considerable research effort has been spent on the economic valuation of biodiversity it remains to be a particularly challenging valuation object valuation practitioners therefore have to use proxies for biodiversity many of which are very simple single species habitats this paper presents a comprehensive and critical review of biodiversity valuation studies with special emphasis on biodiversity valuation in order to depict the state of the art in this research field it develops evaluation criteria so as to identify best practice applications and shows that the field of biodiversity valuation studies is rather heterogeneous regarding both valuation objects and valuation methods on the basis of our evaluation criteria and best practice studies we suggest that to account for the complexity and abstractness of biodiversity multi attribute approaches with encompassing information provision should be used that emphasise the roles biodiversity plays for human well being

a box cox double hurdle model of wildlife valuation the citizen s perspective abstract a stated preference approach is used to elicit the attitudes of the general public towards coyote conservation the payment vehicle is presented in a way that explicitly prompts respondents to adopt a citizen perspective rather than a consumer perspective when responding to the survey to deal with the large numbers of zero responses a box cox double hurdle specification is used to model separately individuals choices about whether to support conservation or not and their choice about the level of support the results show that simpler analyses that do not account explicitly for these two different decisions would lead to misleading conclusions in the study of nuisance wildlife the study uses primary data from prince edward island canada

are union productivity effects overestimated evidence from coal mining the empirical literature of the influence of unions on productivity is extended by considering the effect in an industry with heterogeneous firms recent theoretical papers suggest that in such an industry unions will tend to organize the exogenously more productive firms thus a spurious correlation between unions and productivity may emerge we test this hypothesis by estimating production functions for coal with data from eastern kentucky underground coal mines the aspect of mine heterogeneity that we focus on is the width of the mine s seam of coal wider seams increase productivity empirically we find that unions disproportionately organize mines with wider seams and this accounts for the positive relationship between unions and productivity observed in our data in fact once seam thickness is accounted for the estimated effect of unions on productivity is negative

measuring impartial preference for biodiversity biodiversity undergoes unprecedented rates of erosion despite the important services it provides this is considered evidence that biodiversity is undervalued biodiversity valuation is accordingly a prominent issue in the literature economic valuations are however largely criticized numerous alternatives have been introduced most of them involve participatory protocols aimed at producing high quality results being time consuming and expensive it is difficult to implement and reproduce them at a large scale we produce an easily reproducible inexpensive survey methodology to measure impartial preference for biodiversity we implement it in switzerland through a mail based survey our result is that biodiversity should be ranked after retirement schemes and public transportation but before relations with foreign countries order and security and culture and leisure in the expanses of the state current expenses therefore substantially underestimate the value that swiss people grant to biodiversity our new method is a viable alternative to standard economic valuation given the impartiality achieved at least in the swiss political context our estimate can be used by decision makers to assess the legitimacy of conservation programs or to gauge public support at a philosophical level our measure is relevant for public policies because it captures the stances that people take when they participate in public decisions

economic valuation of biodiversity a comparative study abstract in recent years an intensive debate on the economic valuation of biodiversity has entered the environmental economics literature the present paper seeks to offer first a critical review of key concepts that are essential for a proper understanding of such evaluation issues particular attention is given here to various monetary valuation approaches and to comparative i e meta analytical methods from the perspective of conservation and sustainable use of biodiversity several illustrative examples are presented in order to highlight the usefulness of the various approaches discussed next an attempt is made to infer general findings and lessons from past applied research by means of meta analysis in this context a multi dimensional technique originating from the field of artificial intelligence is deployed it allows us to identify the most important variables responsible for changes in economic estimates of biodiversity

willingness to pay and willingness to accept how much can they differ comment i agree with the point made by edoh y amiran and daniel a hagen 2003 that there can be a substantial or even infinite divergence between the wta and wtp for a public good even where there is a nonzero elasticity of substitution between market goods and the public good provided that the indifference curves are asymptotically bounded with respect to market goods in the manner they describe this is an important point they are also correct to point out that the elasticity of substitution is a local concept whereas their asymptotic boundedness condition applies also for discrete changes my 1991 paper used a local analysis because it was following the structure of the analysis in robert d willig 1976 and alan randall and john r stoll 1980 i wanted to show that while randall and stoll appeared to extend willig s local result on wta versus wtp from price changes to changes in the quantity of a public good the relevant elasticity was in fact different and involved the substitution elasticity as well as the income elasticity i view these points by amiran and hagen as not two separate results but essentially the same result their asymptotic boundedness condition generalizes my zero elasticity of substitution condition to discrete changes the asymptotic boundedness condition can be expressed as follows assuming a bivariate utility function u x q and given a reference point x q associated with a reference utility level u u x q there exists some q q such that for all q q there exists no x such that u x q u in other words no amount of x can substitute for the reduction in public good from q to q q in the case of a zero elasticity of substitution q q but as amiran and hagen show in their theorem 1 this is unnecessarily restrictive when dealing with a discrete reduction in q furthermore their theorem 2 can be viewed as a special case of their theorem 1 in which q 0 which makes q an essential commodity it is well known in consumer theory that the wta to avoid the loss of an essential market good is infinite their theorem 2 extends this result to the case of an essential nonmarket good but as their theorem 1 shows essentialness is not necessary for an infinite wta the boundedness condition is the key and this implies a fundamental lack of substitutability between money market goods and the public good

evidence on macroeconomic complementarities this paper provides empirical evidence on macroeconomic complementarities a restriction on the nature of interaction between individuals in a multiagent setting these models imply that activities across agents will be positively correlated that discrete decisions will be synchronized and that disturbances will be magnified and propagated the paper shows that these implications are consistent with aggregate observations as well as some microeconomic evidence further looking at certain historical episodes such as the national industrial recovery act as well as seasonal fluctuations provides additional support for models with macroeconomic complementarities copyright 1996 by mit press

understanding how income influences willingness to pay for joint programs a more equitable value measure for the less wealthy the preponderance of evidence from many studies is that less wealthy households are subjected to greater exposure per capita and in aggregate to air pollution water pollution and toxic wastes it also is the case that the less wealthy are provided with a disproportionately low amount of other programs to enhance amenities provided by the natural environment such as recreational resources and high quality esthetic opportunities both quality and quantity however to date no study has quantified the scale of this effect on the less wealthy as compared to their more wealthy counterparts when it comes to policy choices made on the basis of benefits analysis this study provides a new equity adjustment method to measure quantitatively the effect of this inequity in the case of public goods

unionism and productivity in west virginia coal mining this study presents econometric estimates of the effects of unionism on productivity in 83 west virginia coal mines in the early 1920s the size detail and panel structure of the data set permit investigation of many possible links between unionism and productivity in contrast to the summary measures reported by most studies the results show that the union effect was not uniform across mines and cannot be represented by a simple shift parameter rather unionism significantly reduced productivity at small mines but not at large mines drawing on historical evidence the author ascribes this differential effect to systematic differences between small and large operations in the quality of management and union leadership

motives behind willingness to pay for improving biodiversity in a water ecosystem economics ethics and social psychology this paper reports on empirical work extending the standard economic approach to valuation by including psychological and philosophical factors more specifically a contingent valuation method survey was applied to biodiversity improvement while simultaneously assessing rights based beliefs consequentialism and the theory of planned behaviour the latter was assessed using measures of attitudes subjective norms and perceptions of control over willingness to pay the results show that standard socio economic explanatory variables are far inferior to those of social psychology and philosophy and that these factors offer a better understanding of the motives behind responses to contingent valuation the implication is that alternative means of measuring an individual s pluralistic values should be taken into account in order to assess the validity and meaning of willingness to pay

preferences for redistribution in the land of opportunities this paper explores how individual preferences for redistribution depend on future income prospects in addition to estimating the impact of individuals socioeconomic background and of their subjective perceptions of future mobility we employ panel data to construct dobjectivet measures of expected gains and losses from redistribution for different categories of individuals we find that such measures have considerable explanatory power and perform better than dgeneral mobilityt indexes we also find that preferences for redistribution respond to individual beliefs on what determines one s position in the social ladder ceteris paribus people who believe that the american society offers equal opportunities are more averse to redistribution d 2004 published by elsevier b v

unions and the incidence of performance linked pay schemes in britain abstract this paper examines the relationship between trade unions and the incidence of share ownership profit sharing and value added schemes in britain the first two schemes are more common in the union sector whilst the third occurs more in non union establishments a distinction is made between weak and strong unions and it is found that performance linked pay schemes are in general less likely to be present if an establishment has a strong union rather than a weak one

unionized construction workers are more productive this paper presents evidence on the effect of unionism on productivity in construction the linkages are distinct from those studied previously in industrial settings apprenticeship training and hiring halls probably raise union productivity while jurisdictional disputes and restrictive work rules lower it using brown and medoff s methodology union productivity measured by value added per employee is 44 to 52 percent higher than nonunion the estimate declines to 17 to 22 percent when estimates of interarea construction price differences are used to deflate value added occupational mix differences and possibly apprenticeship training account for 15 to 27 percent of this difference

social preferences self interest and the demand for redistribution preferences for redistribution may be influenced by values and beliefs about distributive justice as well as by self interest people may prefer more redistribution to the poor if they believe that poverty is caused by circumstances beyond individual control therefore beliefs about the causes of income may affect demand for redistribution alternatively the effect of these beliefs on redistributive preferences may be spurious if they are correlated with income and self interest is not properly controlled for they may also measure incentive cost concerns using social survey data i find that self interest cannot explain the effect of these beliefs on redistributive preferences 2001 elsevier science b v all rights reserved

democratic valuation dv using majority voting principles to value public services the now dominant survey approaches to value public services remain contentious a common explanation is that stated preferences are generally difficult to measure i argue that the key problems of the dominant survey approaches can be explained more specifically by their ambition to measure individuals maximum willingness to pay wtp to estimate wtp researchers need to ask questions involving counterfactual prices to specify doubtful implementation rules and to aggregate preferences in a way that is inconsistent with political rights the procedures engender problems with scenario credibility incentive compatibility adequate information provision and democratic legitimacy as an alternative to the standard stated preference paradigm i propose a democratic valuation approach dv dv measures the exchange value of public services in the political domain in terms of the aggregate valuation implied by the median preferred expenditure level for public services the blueprint for survey design is the public finance referendum with multiple proposals i suggest that empirically straightforward and democratically legitimate exchange values may be a more powerful input to public policy decisions than theoretically correct but empirically problematic estimates of mean willingness to pay

the impact of unionization on motor carrier costs i introduction the increasingly competitive markets fostered by the motor carrier act of 1980 have forced motor carriers to focus on cost saving strategies intended to reduce operating miles fuel consumption and capital and labor expenses there are two reasons unions firms may be at a competitive disadvantage in these efforts first although the union nonunion wage differential has decreased following regulatory reform rose 1987 and hirsch 1988 find that union firms still pay higher wages second managers of unionized firms may have less flexibility in the use of inputs since union work rules restrict the activities and substitutability of drivers terminal workers and terminal facilities indeed harrington 1987 reports that post 1980 trucking expenses are still 40 higher for unionized motor carriers than for nonunion firms unionization may affect carrier cost both by increasing the price of labor and by potentially affecting cost function parameters if union rules make labor less productive the entire cost function will shift upwards for a given set of factor input prices further freeman and medoff 1982 argue that work rules may be expected to result in reduced elasticities of substitution between labor and other inputs in the unionized setting indeed they find that substitution between production labor and other labor in manufacturing is generally lower in unionized settings the impact of unionization on production has been investigated in industries such as construction coal mining hospitals and the cement industry by allen 1984 1986a 1986b byrnes et al 1988 and clark 1980a 1980b the results have been inconclusive with unionized firms being more productive than nonunion firms in some instances and less productive in others studies such as allen 1986c and addison and hirsch 1989 have utilized production function methodologies that use restrictive functional forms which impose homogeneity and identical elasticities of substitution between pairs of inputs allen 1986c examines the relative efficiency of union and nonunion firms with a translog cost function allowing for union effects using intercept and slope parameters that vary by union status in his study of different types of construction projects he finds significant differences between the cost functions for union and nonunion firms but no evidence of the inelasticity of factor substitutions as hypothesized by medoff and freeman in fact his estimates of factor demand elasticities show no discernible pattern for union versus nonunion firms leading him to conclude that work rules do not have the anticipated impact on elasticity the purpose of this study is to test whether unionization impacts motor carrier costs and if so to determine the direction of the impact of particular interest is whether the work rules imposed by the teamster s union have had a significant impact on factor substitutability in unionized firms as argued by freeman and medoff 1982 friedlaender and spady 1981 daughety et al 1985 mcmullen and stanley 1988 grimm et al 1989 and ying s 1990 studies of motor carrier industry costs have used translog cost functions which implicitly assume that union and nonunion cost functions arise from the same production technology this is equivalent to accepting the hypothesis that unionization does not affect the production structure of motor carrier firms if unionization does affect a firm s production process the results from these studies could be biased accordingly this study uses a translog cost function to test for differences in the cost structure of union and nonunion carriers not only is the translog cost function standard in the motor carrier literature permitting comparison of these results with those of previous work it also allows the flexibility necessary to examine the differential impact of unions on cost function parameters and elasticities of substitution between factors
