consumer stated purchasing preferences and corporate social responsibility in the wood products industry a conjoint analysis in the u s and china the impacts of disclosed level of corporate social responsibility csr domestic versus imported origin and type of construction on consumers stated wood product purchasing preferences were examined in the u s and china hierarchical logit models based on a bayesian framework were utilized to test the magnitude and statistical significance of each wood product attribute using survey data results indicate that u s and chinese respondents a were more likely to choose products from manufacturing companies with a higher level of csr rating compared with an unknown one b preferred domestically manufactured wood products compared to imported ones and c expressed higher interest in wood products made of solid wood compared with composites in terms of demographics respondents higher education levels corresponded with higher preferences for products from companies with the highest five star csr rating in the u s statistically significant income effects were detected only in the chinese sample when respondents indicated their purchasing preferences for wood products with three star or five star csr levels implications for improving wood products companies managerial performance and suggestions for future studies are provided

time preference the discounted utility model and health the constant rate discounted utility model is commonly used to represent intertemporal preferences in health care program evaluations this paper examines the appropriateness of this model and argues that the model fails both normatively and descriptively as a representation of individual intertemporal preferences for health outcomes variable rate discounted utility models are more flexible but still require restrictive assumptions and may lead to dynamically inconsistent behaviour the paper concludes by considering two ways of incorporating individual intertemporal preferences in health care program evaluations that allow for complementarity of health outcomes in different time periods

compliance with mandatory environmental reporting in financial statements the case of spain 2001 2003 corporate social ethical and environmental reporting seer should ideally discharge the accountability of an organisation to its stakeholders voluntary reporting has been characterised by a dearth of neutral and objective information such that the advocates of seer recommend that it be made compulsory their underlying rationale is that legally specified disclosure requirements and enforcement mechanisms will enhance the quality of such reporting this paper sets out to explore how realistic this scenario actually is in view of the conflicting interpretations in the literature on this subject to that end a survey of the reporting patterns of 78 of the largest spanish companies between 2001 and 2003 examines the extent of their compliance with the icac 2002 standard which obliged them to make environmental disclosures in their financial statements the results suggest that progressive and improved regulation could increase the volume and quality of seer disclosures they also suggest however that persistent non compliance means that the problems associated with voluntary disclosure still exist finally through an impression management perspective the study reveals the diverse strategies ranging from dismissal to concealment that are employed by companies to avoid transparency as regulation improves and enforcement expectations rise it becomes more difficult to dismiss compulsory reporting norms as a result some firms engage in more complex concealment strategies to attain corporate legitimacy depriving stakeholders of regulatory information the latter point serves to reconcile apparently contradictory explanations in the literature as to whether legitimacy theory might explain partial compliance with seer regulation

alternative approaches to valuing intangible health losses the evidence for multiple sclerosis abstract this study uses both risk risk and risk dollar approaches to assess intangible health losses associated with multiple sclerosis ms using an estimation approach that adjusts for potential perceptional biases that may affect the expressed risk tradeoffs we estimated parameters of the utility function of persons with and without ms as well as the degree of subjects overestimation of the probability of obtaining ms the sample included subjects from the general population and persons with ms we found that marginal utility of income is lower in the state with ms than without it however the difference in marginal utility in the two states was greater for persons without ms than for those with the disease persons with ms overestimated the probability of acquiring ms to a greater extent than did persons within ms correcting for overestimation of this probability the value of intangible loss of a statistical case of ms derived from responses of the general population was us 350 000 to us 500 000 persons with ms were willing to pay somewhat more than this d80 i18 j17

differences in managerial values a study of u s hong kong and prc managers in this study of convergence divergence of managerial values four western developed measures machiavellianism locus of control intolerance of ambiguity and dogmatism and the four dimensions of the eastern developed chinese value survey confucian dynamism human heartedness integration and moral discipline were the measures used the findings indicate that often times both culture and the business environment interact to create a unique set of managerial values in a country

conjoint effect of environmental labeling disclosure of forest of origin and price on consumer preferences for wood products in the us and uk abstract a study that conjointly analyzed the effects of environmental labeling disclosure of forest of origin and price on consumer preferences for wood products was conducted in the us and the uk a choice based elicitation tool was used to mimic a real life situation where a single product was selected over a set of options data collected were analyzed using a conditional logit model certification issued by a government agency or an environmental non government organization both had a favorable effect on consumer preference over a non certified option the most relevant implication of our findings was the negative effect that disclosing information about a product coming from tropical forests had on consumer preferences even compared to a product of unknown origin a decline in product preference was observed along higher price premiums as expected the degree of sensitivity to price changes was affected by demographic characteristics model coefficients were used to estimate market shares of tropical wood products under different scenarios in both countries scenarios explored the effect of environmental certification and price premiums on product market shares

a new approach to valuing a life abstract because the issue of how to put a monetary value on a life will always be controversial this paper presents an alternative approach that can in certain circumstances avoid the use of monetary values the alternative approach uses time as the numeraire this numeraire can handle both the ex ante and ex post approaches to valuing a life after showing how a simple two period consumer choice problem can be translated into terms of time the paper considers an application that involves reformulating the data used to evaluate the 55 mph speed limit decision in the united states

using rank data to estimate health state utility models in this paper we report the estimation of conditional logistic regression models for the health utilities index mark 2 and the sf 6d using ordinal preference data the results are compared to the conventional regression models estimated from standard gamble data and to the observed mean standard gamble health state valuations for both the hui2 and the sf 6d the models estimated using ordinal data are broadly comparable to the models estimated on standard gamble data and the predictive performance of these models is close to that of the standard gamble models our research indicates that ordinal data have the potential to provide useful insights into community health state preferences however important questions remain

pressure and the division of a public budget this paper considers the division of a public budget among competing interests the planner determines the optimal allocation by maximizing a weighted social welfare function these weights reflect society s attitudes to different recipient groups and are not constrained to be constant by exerting pressure the recipients can attempt to manipulate the weights and hence influence the division of the budget the amount of resources used on pressure and the effects on the preference weights are calculated an important parameter in the model is the elasticity of pressure for which an appropriate estimate is presented from the case of competition for a share of a health services budget in norway

building institutions based on information disclosure lessons from gri s sustainability reporting abstract global reporting initiative gri is the best known framework for voluntary reporting of environmental and social performance by business worldwide using extensive empirical data including interviews and documentary analysis we examine gri s organizational field and conclude that since its modest beginnings in 1999 gri has been by several measures a successful institutionalization project but the institutional logic of this new entity as an instrument for corporate sustainability management leaves out one of the central elements of the initial vision for gri as a mobilizing agent for many societal actors this emergent logic reflects gri s dominant constituency large global companies and financial institutions and international business management consultancies and not the less active civil society organizations and organized labor we attribute these developments to factors such as building gri within the existing institutional structures the highly inclusive multistakeholder process and the underdeveloped base of information users from the institutional theory perspective this case shows how the process of institutionalization is deeply affected by initial strategies of the founders and how it reproduces existing power relations from the governance perspective this case leads us to question the power of commodified information to mobilize civil society and to strengthen governance based on partnerships

who will meet china s import demand for forest products summary via computable general equilibrium modeling we find that as a result of economic growth yuan appreciation and logging restrictions in china china s imports and exports of forest products would dramatically increase and china s imports would have displacement effects as timber exporting countries would increase their exports to china while reducing their shipments to other countries such displacement effects would make pressure on forests in supplying countries less than they otherwise might be global economic growth is a dominant driving force for china s imports russia southeast asia and africa would remain major foreign suppliers of logs to china while supply sources for chinese imported lumber and paper products would be relatively diverse

cost effectiveness utility analyses do current decision rules lead us to where we want to be despite the growing literature on economic evaluation of health care programmes little attention has been paid to the theoretical foundations of cost effectiveness and cost utility analyses and the validity of the decision rules adopted as methods of achieving the stated goals we show that although applications of the techniques can be used to pursue some managerial objectives in the context of highly constrained environments such applications are inconsistent with both welfare economic objectives and the interpretations of the findings of these applications alternative strategies are identified as potential and practical methods for pursuing welfare economic objectives

structural reliability of conjoint measurement in health care an empirical investigation this paper is concerned with the structural reliability of conjoint measurement when applied in a health care setting the clinical context was the diagnosis and treatment of knee injuries a conjoint measurement study was conducted which used the pairwise choice approach to preference elicitation each choice included two scenarios a conventional treatment approach to management arthroscopy and an approach using magnetic resonance imaging in order to test for structural reliability two separate conjoint measurement exercises were conducted exercise a where scenarios were defined in terms of three attributes and exercise b where scenarios included all four attributes the assessment of structural reliability involved a comparison of two random effects probit models for exercises a and b data were collected on a total of 176 students of sports science the results strongly indicate that the models for the two exercises are different although the instability is limited to the constant term and a sin

using cheap talk as a test of validity in choice experiments abstract in two experiments on the choice of consumer goods the estimated marginal willingness to pay for food is found to be lower in the survey version with cheap talk our test can be seen as a test of hypothetical bias this implies that we cannot reject the hypothesis of a hypothetical bias for marginal wtp in choice experiments

what do customers want from improved residential electricity services evidence from a choice experiment abstract improvements in customer satisfaction as well as product service quality represent a common objective of all businesses and electricity services are no exception using choice experiments and a mixed logit model this study quantitatively analyzes customers preferences and their marginal willingness to pay for improved residential electricity services the study provides an ex ante evaluation of customers acceptance of hypothetical electricity services according to the results customers consider the electricity bill and the electricity mix as the two most important attributes when choosing their electricity services customers are willing to pay 2 2 more in the average electricity bill an additional monthly electricity bill of krw 1 064 usd 0 96 for a significant increase in the share of renewable energy which is far less than the actual cost of achieving this renewable target therefore it is better to maintain the current electricity mix in principle and the renewable share should be gradually expanded instead of making a sudden change in the electricity mix in addition customers are willing to pay krw 6 793 usd 6 15 more to reduce blackouts once in a year and krw 64 year usd 0 06 year to reduce a minute of each blackout

equivalence scales and the costs of disability abstract the impact of disability on household welfare is estimated by equivalence scales using data from the 1986 1987 fes disability survey three methods of identifying scales from cross section data are considered these imply a series of restrictions that are tested on quadratic logarithmic engel curves the results indicate that there are substantial consumption costs associated with physical disability

evolving theories of sustainability and firms history future directions and implications for renewable energy research abstract sustainability has become a critical perspective in managing firms via a holistic approach by considering economic environmental and social dimensions of firms with the rising significance of sustainable development the theories of sustainability in firms have evolved during the past six decades this article offers a critical review of the evolving theories linking sustainability to firms and discusses their implications for future renewable energy research the relationships among different theories are critically analysed and the directions for future research are discussed the paper shows that the main theories linking sustainability to firms in a chronological order are 1 corporate social responsibility 2 stakeholder theory 3 corporate sustainability and 4 green economics currently various innovative approaches and new theories emerged such as co evolution theory and multi level perspective reflecting three directions of theory development namely 1 shifting from what to how 2 growing use of interdisciplinary approach and 3 towards broader systems renewable energy studies associated with firms and future research opportunities in this area are also critically analysed the comprehensive review offered in this paper provides a useful reference for policy makers corporate managers and researchers interested in corporate sustainability and renewable energy related studies

applications of cost benefit analysis to health care departures from welfare economic theory in applying the principles of cost benefit analysis to real world problems of resource allocation particular care must be taken to ensure that the welfare economic theory which underlies the cost benefit technique is adhered to major problems arise where costs and benefits are used interchangeably to represent the good and bad attributes of a programme furthermore in the presence of mutually exclusive projects focussing attention upon the net benefits or cost benefit ratios of individual projects as opposed to the net benefits of the use of budgeted resources can lead to biased estimates of the shadow price of projects and consequently errors in analysts conclusions as a result economic appraisals of individual projects are not directly relevant for choosing between mutually exclusive projects of different sizes both types of problem are illustrated by reference to both simple examples and published economic appraisals of health care techniques integer programming is proposed and demonstrated as a method of selecting between mutually exclusive projects

qalys versus hyes this paper explores the claim that qalys are liable to misrepresent consumer preferences and hence lead to decision makers choosing options which are not those preferred by the public it also considers the claim that hyes do not suffer from this defect we argue that none of the examples offered to date demonstrate the alleged tendency of qalys to misrepresent preferences we also show that hyes are identical to qaly scores obtained from a time tradeoff experiment and therefore that the assumptions about preferences underlying hyes are just as restrictive as those underlying tto based qalys

on the aggregation of health status measures in the present paper we address the problem of finding conditions under which aggregation of individual health status measurements e g qalys is meaningful in the sense that there is a universal unit of measurement for health the problem is studied in a model where different aspects of health take the form of lancasterian characteristics to be produced by the individuals using commodities obtained in the market for a meaningful unit of measurement to exist marginal rates of substitution between different aspects of health should not differ among individuals and for this to happen in an equilibrium of the economy considered certain assumptions of separability of technology and or preferences must be satisfied this means that universal measures of health will be meaningful only if there are not too many spillovers in achieving different aspects of health

accounting for future costs in medical cost effectiveness analysis most medical cost effectiveness analyses include future costs only for related illnesses but this approach is controversial this paper demonstrates that cost effectiveness analysis is consistent with lifetime utility maximization only if it includes all future medical and non medical expenditures estimates of the magnitude of these future costs suggest that they may substantially alter both the absolute and relative cost effectiveness of medical interventions particularly when an intervention increases length of life more than quality of life in older populations current methods overstate the cost effectiveness of interventions which extend life compared to interventions which improve the quality of life

environmental reporting in the spanish wind energy sector an institutional view abstract the aim of this paper is to explore the relevance of institutional influences on corporate environmental reporting practices the wind energy sector in spain was chosen for analysis because of its rapid growth and significant impact on moves towards cleaner energy production a content analysis of recent sustainability reports 2005 2009 from seven main wind energy companies facilitated a longitudinal comparison of the levels of compliance with global reporting initiative indicators of sustainability results show that initial institutional pressures for reporting have been replaced by imitation by companies of each other s practices leading to a reduction in the differences between environmental disclosures results confirm the importance of examining different institutional pressures on disclosure practices to development of policy however a key finding is that the disclosures have been minimal and their lack of effectiveness and unreliability mean they are not conducive to the notion of increasing transparency in the wind generated clean energy electricity sector as a result the credibility of relying on a voluntary sustainability standard such as the global reporting initiative gri as an incentive for informative environmental reporting is challenged

using a discrete choice experiment to estimate health state utility values in this study we explored a novel application of the discrete choice experiment dce that resembles the time trade off tto task to estimate values on the health utility scale for the eq 5d the dce was tested in a survey alongside the tto in a sample of english speaking canadians recruited by a market research company the study found that the dce is able to derive logical and consistent values for health states valued on the full health dead scale the dce overcame some issues identified in the version of tto currently used to value eq 5d notably allowing for fewer data exclusions and incorporating values considered worse than dead without introducing a separate valuation procedure this has important implications for providing robust values that represent the preferences of all respondents

models of quality adjusted life years when health varies over time survey and analysis quality adjusted life year qaly models are widely used for economic evaluation in the health care sector in the first part of the paper we establish an overview of qaly models where health varies over time and provide a theo retical analysis of model identification and parameter estimation from time trade off tto and standard gamble sg scores we investigate deterministic and probabilistic models and consider five different families of discounting functions in all the second part of the paper discusses four issues recurrently debated in the literature this discussion includes questioning the sg method as the gold standard for estimation of the health state index re examining the role of the constant proportional trade off condition revisiting the problem of double dis counting of qalys and suggesting that it is not a matter of choosing between tto and sg procedures as the combination of these two can be used to disen tangle risk aversion from discounting we find that caution must be taken when drawing conclusions from models with chronic health states to situations where health varies over time one notable difference is that in the former case risk aversion may be indistinguishable from discounting models of quality adjusted life years qalys are widely used as health related quality of life measures for economic evaluation in the health care sector in its simplest form the qaly approach assumes that the utility of a profile of health states over time may be estimated by adding the values of the constituent health states in the health profile in more sophisticated models health events occurring in the future may be discounted or risk adjusted

measurement of health state utilities for economic appraisal health status measurement for use in economic appraisal of health care programmes is reviewed in this paper with particular emphasis on utility measurement a framework for economic appraisal is presented displaying the various components that must be measured and showing how the three forms of analysis cost effectiveness analysis cost benefit analysis and cost utility analysis relate to the framework and to each other one of the components in the framework is health status it can be measured using ad hoc numeric scales willingness to pay receive or health state utilities the determination of health state utilities is reviewed covering the following issues alternative sources of utilities health state descriptions multi attribute utility approach determination of appropriate subjects utility aggregation and accuracy three measurement techniques for health state utilities are described in detail rating scale standard gamble and time trade off the use of these methods is described for both chronic and temporary health states and for both health states considered better than death and those considered worse than death

incorporating psycho social considerations into health valuation an experimental study abstract this study used multiple elicitation question modes and group discussions to value psycho social considerations associated with public perceptions of health risks values for saving 100 statistical lives in six different policy contexts varied by 50 largely due to psycho social considerations of choice and control a currency effect was found value of life differentials were smaller when questions were framed directly in the currency of lives saved rather than willingness to pay or public spending to save lives discussions reduced but did not eliminate inconsistencies and slightly increased the relative valuations of health interventions involving less choice and control by those at risk

economic evaluation of services for a national health scheme the case for a fairness based framework in this paper we argue that the usual framework for evaluating health services may need modification in the context of a national health scheme nhs some costs and benefits may need to be ignored or discounted others included at face value and some transfer payments included in the decision algorithm in contrast with the standard framework we argue that economic evaluation in the context of an nhs should focus on social transfers between taxpayers and beneficiaries and that the nature and scope of these transfers is determined by the level of social generosity some of the implications of a modified framework are illustrated with a re examination of i costs and transfer payments ii unrelated future costs iii moral hazard and iv the rule that marginal costs should equal marginal benefits we argue that an explicitly fairness based framework is needed for the evaluation of services in an nhs in contrast the usual welfare economic theoretic framework facilitates the sidelining of issues of fairness

corporate social responsibility in europe and the u s insights from businesses self presentations the paper compares the extent and content of businesses communications about corporate social responsibility csr in france the netherlands the u k and the u s in particular the study investigates the nature of csr principles processes and stakeholder issues discussed in web pages the results show that businesses in the four countries do not display the same eagerness to appear as socially responsible and employ diverse means to convey social responsibility images

qalys versus hyes what s right and what s wrong a review of the controversy abstract the paper uses an axiomatic approach to the description of individual preferences for health status sequences to resolve the major issues at stake in the recent controversy over qalys versus hyes while the hye accounts for an individual s time preference for health qaly scores based on the time trade off method will generally differ from the number of hyes hyes do not represent preferences for health under risk unless the utility function for reference flows of health is linear collapsing the two step hye assessment procedure into a single step entails a loss of information as regards the utility of a health status sequence although the procedure does represent preferences for health it fails to supply a description in terms of hyes in the case of risk as a remedy a modified hye approach is proposed

standard gamble time trade off and rating scale experimental results on the ranking properties of qalys this paper compares the relative performance of quality adjusted life years qalys based on quality weights elicited by rating scale rs time trade off tto and standard gamble sg the standard against which relative performance is assessed is individual preference elicited by direct ranking the correlation between predicted and direct ranking is significantly higher for tto qalys than for rs qalys and sg qalys this holds both based on mean spearman rank correlation coefficients calculated per individual and based on two social choice rules the method of majority voting and the borda rule undiscounted tto qalys are more consistent with direct ranking than discounted tto qalys

the corporate social performance financial performance link strategic managers are consistently faced with the decision of how to allocate scarce corporate resources in an environment that is placing more and more pressures on them recent scholarship in strategic management suggests that many of these pressures come directly from sources associated with social issues in management rather than traditional arenas of strategic management using a greatly improved source of data on corporate social performance this paper reports the results of a rigorous study of the empirical linkages between financial and social performance corporate social performance csp is found to be positively associated with prior financial performance supporting the theory that slack resource availability and csp are positively related csp is also found to be positively associated with future financial performance supporting the theory that good management and csp are positively related 1997 by john wiley sons ltd
