economic valuation of the threat posed by the establishment of the asian tiger mosquito in australia invasive species policy could be better informed if we understood how much people value reductions in the risks posed by these organisms this study investigates the public s willingness to pay wtp for additional measures to reduce the risk of invasion of the australian mainland by the asian tiger mosquito atm the study contributes to the literature by applying a stated preference method to estimate the public s wtp to reduce the risk of an atm invasion expressed as a change in probability it is the first ex ante invasive species analysis to test over two discrete invasion reduction probabilities based on management effort further to overcome the challenges in valuing changes in probabilities the study presented respondents with a well defined discrete difference in the final probability with one scenario reducing risk from 50 to 25 and the other from 50 to 5 we find a significant difference in the mean wtp values between these two scenarios a 67 vs a 90 the overall conclusion is that estimated benefits of reducing the probability of an atm incursion outweigh the costs

corporate philanthropic disaster response and ownership type evidence from chinese firms response to the sichuan earthquake this article examines whether the charitable giving amount and likelihood of firm response to catastrophic events relate to firms ownership type using a unique dataset of listed firms in china where state ownership is still prevalent based on the data of chinese firms response to the 2008 sichuan earthquake we find that the extent of corporate contributions for state owned firms following this disaster is less than that for private firms state owned firms are also less likely to respond in this disaster compared to private firms the results also reveal that firm size profitability geography cash resource available and leverage affect firms philanthropic disaster response behavior in china

statistical efficiency of double bounded dichotomous choice contingent valuation the statistical efficiency of conventional dichotomous choice contingent valuation surveys can be improved by asking each respondent a second dichotomous choice question which depends on the response to the first question if the first response is yes the second bid is some amount greater than the first bid while if the first response is no the second bid is some amount smaller this double bounded approach is shown to be asymptotically more efficient than the conventional singlebounded approach using data from a survey of californians regarding their willingness to pay for wetlands in the san joaquin valley we show that in a finite sample the gain in efficiency can be very substantial

organizational membership and environmental ethics a comparison of managers in state owned firms collectives private firms and joint ventures in china abstract this study empirically examines the relationship between organizational type and the environmental ethical orientation of managers in the people s republic of china prc on three dimensions stewardship and long and short term utilitarianism it was found that chinese managers uniformly self report strong ethical commitments to environmental protection in addition organizational type was found to be a significant predictor for the different ethical dimensions overall managers in state owned firms uniformly reported the strongest values managers in private firms on the other hand self reported lower values and appeared relatively more skeptical of emergent utilitarian arguments that economic performance and environmental performance are compatible in the short term

sensitivity to scale in contingent valuation the importance of the budget constraint the possible insensitivity of willingness to pay wtp values to changes in scale continues to cause concern within the contingent valuation cv literature although several reasons for this phenomenon have been suggested empirical evidence both supports and refutes insensitivity this paper presents data that suggest that insensitivity may be significantly determined by the individual s budget constraint the higher the proportion of income the expressed wtp represents the greater the insensitivity of that wtp to changes in the scale of the good irrespective of changes in underlying marginal utility the methodological implication for cv studies in health care is outlined

estimation using contingent valuation data from a dichotomous choice with follow up questionnaire reply abstract our original article proposed that the two yes no willingness to pay wtp responses produced by this survey format should be viewed as a pair of jointly distributed correlated discrete random variables the comparison model the conventional approach to estimation using these types of data contained a programming error correction alters the results from the comparison model but our original claim that estimation by conventional methods can produce misleading inferences if ours is the appropriate specification still stands this is especially true if negative wtp is precluded when e wtp is calculated

does altruism undermine existence value abstract the debate over the use of contingent valuation for existence values or passive use values has failed to explore the validity of motives for such values one potential motive altruism has conflicting implications for benefit cost analysis depending on whether the altruist is paternalistic this paper constructs models of three types of altruism and shows how benefit cost analysis responds to each type of altruism how damage assessment and restoration depend on each type and the implications of a population of heterogeneous altruists

substitution between unemployment insurance and workers compensation abstract this paper extends the literature on post injury duration of absence from work by developing a model that incorporates substitution between unemployment insurance benefits and workers compensation a theoretical analysis is presented in which the worker maximizes expected utility over four possible states of nature the model is tested empirically using pooled cross section and time series data at the two digit industry level the main findings support the predictions of the model an increase in workers compensation benefits increases the average duration of accidents with an elasticity of 0 9 1 4 while an increase in unemployment insurance payments reduces the average duration of accidents with an elasticity of 0 5 0 7

separating the reporting effects from the injury rate effects of workers compensation insurance a hedonic simulation this paper presents a numerical simulation based on data from the early 1970s to investigate the economic links between labor market outcomes and the workers compensation insurance system the results suggest that in most cases any of three changes in the system more generous benefits more accurate categorization of insurance claims or more complete experience rating of premiums will slightly reduce the actual number of work related injuries but will dramatically increase the number of insurance claims filed the authors conclude that changes in self reported injuries can produce significant misimpressions of the safety incentives created by the workers compensation insurance system

the case of risk premia for risky jobs revisited abstract the empirical evidence concerning the existence of risk premia for risky jobs is contradictory some results support the existence of these premia while others do not this note provides a theoretical justification for these contradictory results in a fairly general model where firms and workers can effect the probability of a workplace accident

consumer support for corporate social responsibility csr the role of religion and values ethical behavior among businesses has gained significant prominence in recent years survey evidence shows that asian consumers demand for greater social responsibility among businesses thus a deeper understanding of the factors that contribute to such a demand is useful this study examines the influence of religiosity and values on corporate social responsibility csr support among consumers in hong kong and singapore primary data collected among consumers in these cities point to a significant direct relationship between religiosity and csr support in hong kong this attitude is due both to altruistic as well as for egotistical or face saving reasons in singapore this is mainly due to the latter the results imply that different motivations should guide csr strategies in these two cities

do contingent valuation estimates pass a scope test a meta analysis abstract this paper considers the scope test proposed to judge the internal consistency of contingent valuation estimates the test is shown to be quite sensitive to the maintained hypotheses required to derive fairly precise expectations for the properties of wtp functions and therefore a different approach may be needed in gauging the reliability of cv this paper describes an approach that relies on a weight of the evidence criterion and uses meta analysis to develop a systematic appraisal of what the economic values of changes in amenity resources are the approach is illustrated for the case of estimating people s willingness to pay for improving or maintaining visibility at the national parks

contingent valuation a practical alternative when prices aren t available a person may be willing to make an economic tradeoff to assure that a wilderness area or scenic resource is protected even if neither that person nor perhaps anyone else will actually visit this area this tradeoff is commonly labeled passive use value contingent valuation studies ask questions that help to reveal the monetary tradeoff each person would make concerning the value of goods or services such surveys are a practical alternative approach for eliciting the value of public goods including those with passive use considerations first i discuss the exxon valdez oil spill of march 1989 focusing on why it is important to measure monetary tradeoffs for goods where passive use considerations loom large although discussions of contingent valuation often focus on whether the method is sufficiently reliable for use in assessing natural resource damages in lawsuits it is important to remember that most estimates from contingent valuation studies are used in benefit cost assessments not natural resource damage assessments those working on benefit cost analysis have long recognized that goods and impacts that cannot be quantified are valued implicitly by giving them a limitless value when government regulations preclude certain activities or giving them a value of zero by leaving certain consequences out of the analysis contingent valuation offers a practical alternative for reducing the use of either of these extreme choices i put forward an affirmative case for contingent valuation and address a number of the concerns that have arisen

stock market s reaction to disclosure of environmental violations evidence from china the stock market s reaction to information disclosure of environmental violation events eves is investigated multi dimensionally for chinese listed companies including variables such as pollution types information disclosure sources information disclosure levels modernization levels of the region where the company locates ultimate ownership of the company and ownership held by the largest shareholder using the method of event study daily abnormal return ar and accumulative abnormal return car are calculated under different event window for examining the extent to which the stock market responds to the eves furthermore statistical significance of the difference in stock market reaction is compared between event firms with different characteristics the relationship between car and its impact factors is examined by multivariate analysis the findings reveal that the average reduction in market value is estimated to be much lower than the estimated changes in market value for similar events in other countries demonstrating that the negative environmental events of chinese listed companies currently have weak impact on the stock market

corporate social responsibility ownership structure and political interference evidence from china prior research suggests that ownership structure is associated to corporate social responsibility csr in developed countries this article examines whether and how ownership structure affects csr in emerging markets using chinese firms social responsibility ranking our empirical evidences show that for non state owned firms corporate ownership dispersion is positively associated to csr however for state owned firms whose controlling shareholder is the state this relation is reversed we attribute the reversed relationship to political interferences and further test this hypothesis by demonstrating that regional economic development is negatively related to csr for state owned firms due to decreased political interference in more developed areas this study is the first to directly examine the relationship between the dispersion of corporate ownership and csr in emerging markets and our results depict that it is important to consider ownership type in assessing csr in emerging market where state ownership is still prevalent such as china the results also reveal that firm size profitability employee power leverage and growth opportunity affect csr in china

environmental and resource economics a canadian retrospective the paper reviews research contributions to environmental and resource economics by scholars in canada we focus mainly on work from the past 25 years but also highlight earlier pathbreaking work we begin by looking at broad trends in research both internationally and within canada we then review canadian contributions to various topics in the field canadians have played a leading role in the development of the field especially in resource economics international environmental economics and the valuation of environmental amenities

preferences in the future environmental economics has been much occupied with the discount rate which is the value of future costs and benefits relative to present costsor benefits but at least as important is the question of whatshould be discounted that is what the value of those future environmentalbenefits is to future generations this paper analyzes the role for futurepreferences and discusses the state of knowledge i argue that theappropriate discount rate is the market one and that the real problemis determining future willingness to pay this approach makes clearerthe connection between discounting and the valuation debate this paper focuses on two features that have been prominent in that debate existence value and reference dependence i argue that thereis a vital connection between the two constructs and that this link yieldsimportant implications for future willingness to pay

diagnosing insensitivity to scope in contingent valuation sensitivity to scope is considered a desirable property of contingent valuation studies and often treated as a necessary condition for validity we first provide an overview of scope insensitivity explanations put forth in the environmental valuation literature then we analyze data from a contingent valuation survey eliciting willingness to pay to prevent oil spills of four different magnitudes in arctic norway in the baseline analysis the scope inference is ambiguous there is only statistical difference in willingness to pay to avoid a very large versus small oil spill nok 1869 and nok 1086 respectively however further explorations show that several confounding factors suggested in the literature influence the scope inference the scope sensitivity improves when we control for subjective probabilities of amenity provision exclude respondents based on the debriefing questions take into consideration the sample sizes and impose diminishing marginal utility overall the analysis supports an emerging view in the contingent valuation literature suggesting that statistical scope insensitivity is not a sufficient reason for deeming a study invalid

separating moral hazard from adverse selection and learning in automobile insurance longitudinal evidence from france the identification of information problems in different markets is a challenging issue in the economic literature this paper performs tests of residual asymmetric information in the french automobile insurance market for the 1995 1997 period this market is characterized by the presence of a regulated experiencerating scheme bonus malus contract choices are strongly associated with the bonus malus of policyholders we have access to longitudinal survey data with dynamic information both on claims and accidents we propose a causality test to distinguish pathways through which a positive correlation arises between contract choice and accidents we find evidence of moral hazard among a sub group of policyholders with significant driving experience 5 15 years we distinguish this moral hazard estimate from adverse selection and learning policyholders with less experience have a combination of learning and moral hazard whereas no residual information problem is found for policyholders with more than 15 years of experience

factors that drive chinese listed companies in voluntary disclosure of environmental information based on the institutional theory this article attempts to examine two consecutive questions regarding the impact of various factors on corporate decision in environmental information disclosure eid 1 whether or not to disclose and 2 the level of disclosure the relevance of these factors is empirically tested using data collected from publicly listed manufacturing companies from 2006 to 2008 in china some interesting findings appear we find that firms that are state owned those that operate in environmentally sensitive industries those having more industrial peers engaged in eid and those with better reputation are more likely to disclose environmental information when it comes to the content of eid variables that attempt to capture external institutional pressures exhibit either no or weak explanatory power only the variable of organizational image and reputation is demonstrated to have a significant impact on both the act and the content of eid this study provides a snapshot of the dialogues between constituencies in the organizational field and eid development

business ethics and finance in greater china synthesis and future directions in sustainability csr and fraud following the financial crisis and recent recession the center of gravity of global economic growth and competitiveness is shifting toward emerging economies as a leading and increasingly influential emerging economy china is currently attracting the attention of academics practitioners and policy makers there has been an increase in research interest in and publications on issues relating to china within high quality international academic journals we therefore organized a special issue conference in conjunction with the journal of business ethics jbe in lhasa tibet on may 19 20 2014 on business ethics in greater china past present and future the papers for the special issue focused on the intersection of ethics and finance and fit within one of the three themes environment and sustainability corporate social responsibility and fraud within these themes issues of intellectual capital protection gender equality political connections regional development investor protection corporate stewardship trust and corruption and corporate transparency each play a significant role in this paper we survey these studies and the related literature to provide a comprehensive coverage of business ethics and finance issues that affect china

plausible responsiveness to scope in contingent valuation plausible responsiveness to scope is a question of economic significance in addition to statistical significance of the scope test in contingent valuation we briefly review the history of the scope test in order to place the current issue in the context of the bp deepwater horizon oil spill as a result of the review we gain insights into how the issue of scope adequacy arose twenty years after it was first mentioned by the noaa panel on contingent valuation following the exxon valdez oil spill we then provide a review of desvousges mathews and train 2012 who promote the adding up test to identify inadequate responsiveness to scope adequacy the adding up test is a test of the construct validity of the contingent valuation method but is flawed as a measure of economic significance we propose scope elasticity of willingness to pay as a measure of economic significance a simulation suggests a likely range of elasticity estimates given linear and quadratic functional forms for the willingness to pay function in order to illustrate the ease of implementation of scope elasticity within the context of the standard scope test we calculate scope elasticity with willingness to pay estimates from several studies describe two studies that directly estimate scope elasticity and estimate scope elasticity with primary data from two studies all of these empirical estimates of scope elasticity fall within the range of scope elasticity suggested by the simulation scope elasticity provides a practical way forward relative to the adding up test on the issue of economic significance of scope effects

income tax evasion an intersectoral analysis abstract this paper develops an intersectoral model of income tax evasion with general equilibrium effects key elements of the model are imperfectly substitutable outputs from the compliant and evading sectors and workers with heterogeneous evasion costs the model allows for biased public expenditures a wide range of behavioural responses and both legitimate and criminal activities evading tax as well as tax avoidance activities qualitative and quantitative assessments are undertaken for the effects of tax rate changes on evasion activity relative output prices and real tax revenues this approach offers useful findings for taxation policy and is amenable to further analytical extensions

political connections and industrial pollution evidence based on state ownership and environmental levies in china we investigate how state involvement in the ownership of non listed entrepreneurial firms affects pollution fees levied by national and provincial governments in china environmental levies while the national government sets minimum environmental standards provincial governments can enact requirements that exceed these minimums and they are largely responsible for enforcing even the national standards so environmental levies can measure concessions that provinces make to encourage development and employment furthermore state ownership is a good proxy for a firm s political connections which can influence the relationship between the firm and the environmental authorities we find that firms with state ownership pay lower environmental levies which indicates that concessions are made for political or economic purposes however these concessions are conditional on the level of development of the province offering them with better developed provinces providing fewer concessions

do lenders value corporate social responsibility evidence from china drawing on risk mitigation theory this article examines whether the improvement of firms social performance reduces debt financing costs cdfs in china the world s largest emerging market employing both the ordinary least square ols and the two stage instrumental variable regression methods we find that improved corporate social responsibility csr reduces the cdf when firms csr investment is lower than an optimal level however this relationship is reversed after the csr investment exceeds the optimal level firms with extremely low or extremely high csr are subject to a higher cdf the results also suggest that the optimal csr level for small firms is higher than that for large firms this study is the first to document a u shaped relationship between csr and cdf and also the first to investigate this relationship within an emerging market context

impacts of corporate code of conduct on labor standards a case study of reebok s athletic footwear supplier factory in china this study examines the social impacts of labor related corporate social responsibility csr policies or corporate codes of conduct on upholding labor standards through a case study of csr discourses and codes implementation of reebok a leading branded company enjoying a high profiled image for its human rights achievement in a large taiwanese invested athletic footwear factory located in south china i find although implementation of reebok labor related codes has resulted in a race to ethical and legal minimum labor standards when notoriously inhumane and seriously illegal labor rights abuses were curbed chinese workers were forced to work harder and faster but earned less payment and the employee elected trade union installed through codes implementation operated more like a company union rather than an autonomous workers organization representing worker interests in order to explain the paradoxical effects of reebok labor related codes on labor standards i argue the result is determined by both structural forces and agency related factors embedded in industrial national and local contexts to put it shortly i find the effectiveness of reebok labor related codes is constrained not only by unsolved tension between reebok s impetus for profit maximization and commitment to workers human rights but also by hard nosed competition realities at marketplace and chinese government s insufficient protection of labor rights despite drawing merely from a single case study these findings illuminate key determinants inhibiting the effectiveness of labor related csr policies or codes in upholding labor standards and hence two possible way outs of the deadlock 1 sharing cost for improving labor standards among key players in global supply chain and 2 combining regulatory power of voluntary codes and compulsory state legislations

regulatory sanctions on independent directors and their consequences to the director labor market evidence from china we investigate the regulatory sanctions imposed on independent directors for their firms financial frauds in china these regulatory sanctions are prima facie evidence of significant lapses in business ethics during the period 2003 2010 302 person time independent directors were penalized by the regulator the china securities regulatory commission the csrc and the two stock exchanges we find that the independent directors with accounting experiences are more likely to be penalized by the csrc though they do not suffer more severe penalties than do the other sanctioned independent directors we also find that independent directors suffer less severe penalties than do the insider directors these results are consistent with the hypothesis that the sanctions on independent directors are tied to their assumed ethical and legal responsibilities following a regulatory sanction penalized independent directors experience a significant decline in the number of other board seats held however they can gain board seats in better quality firms we find that interlocked firms that share penalized independent directors with the fraud firm do not suffer from a valuation decline overall our results suggest that regulatory sanctions have not triggered further sanctions on the penalized directors in the labor market but they have instead created a disincentive for these directors to serve on the company boards of high risk firms

nonuse values in benefit cost analysis benefit cost analysis bca is a pragmatic realization of the theory of welfare economics much of the research associated with bca has sought to expand the types of benefits that can be measured in dollar terms with this research there has been a progressive movement of goods and services from the set without measures usually designated as intangibles in bca terminology to the set with for example the recreational services provided by projects associated with dams for hydroelectric power or flood control were regarded as intangible until the development of the travel cost model for estimating the demand for outdoor recreation sites one of the current frontiers in bca research is associated with modeling and measuring nonuse benefits in contrast to the past efforts with intangibles research on this topic has remained controversial with few direct effects on the practice of applied welfare economics there are two principal reasons for this outcome first there has not been an accepted set of definitions for nonuse benefits and second applied studies with empirical estimates of nonuse benefits have until recently been non existent clearly these problems are related a consistent set of definitions is a necessary prerequisite for empirical implementation i will argue that consistent definitions for nonuse benefits have been elusive because the conceptual frameworks used in the literature to describe its primary components option value and existence values are not mutually consistent in the process of demonstrating this result i will describe the elements of a consistent framework for treating both use and nonuse benefits and apply it in explaining some of the problems with the available empirical estimates of nonuse benefits

valuing riverside wetlands the case of the donau auen national park abstract for two decades the establishment of the donau auen national park east of vienna has been on the political agenda in austria since 1991 concrete proposals have been worked out for several variants of a national park including hydraulic engineering concepts and hydroelectric power stations within this planning process a cost benefit analysis was carried out to estimate the economic impacts of the proposed projects one crucial question was how to value the ecological quality of wetlands these environmental goods were valued by means of a willingness to pay wtp survey two different kinds of variables were defined 1 costs and benefits depending on direct anthropocentric use including energy production with hydroelectric power stations shipping groundwater protection stabilisation of the river bed to stop channel erosion visitors benefits forestry farming fishing hunting and the costs of establishing a national park based on these variables the net present value for variants with hydroelectric power stations is higher than for variants without electricity production on the contrary the internal interest rate and the benefit cost ratio is higher for a pure national park without electricity production 2 taking also the austrians wtp for the donau auen national park as a substitute measure for ecological values into account only 20 percent of the wtp which was measured by means of contingent valuation is needed to make the net present value of the best national park variant equal to that of the best hydroelectric power variant this shows that the protection of natural goods like wetlands in a natural state might be more efficient from an economic viewpoint than development projects

globalization and the environment determinants of firm self regulation in china critics assert that globalization is detrimental to the environment because it encourages location of polluting industries in countries with low environmental regulations we suggest that globalization might also have positive environmental effects because global ties increase self regulation pressures on firms in low regulation countries using survey data from firms in china we find that multinational ownership multinational customers and exports to developed countries increase self regulation of environmental performance

an investigation of part whole biases in contingent valuation studies abstract part whole bias is a possible explanation for nonuse contingent valuation estimates that are insensitive to marginal changes in environmental commodities our empirical analyses reveal no statistically significant differences in willingness to pay of independent samples of nonusers to prevent 2000 20 000 or 200 000 migratory waterfowl deaths in the central flyway all numbers less than 2 of the waterfowl population five alternative propositions for explaining this empirical findings do not provide a completely satisfactory explanation more research is necessary to investigate appropriate commodity metrics sample sizes for small changes in environmental commodities and consider how respondents evaluate small changes in environmental commodities

contingent valuation controversies and evidence contingent valuation cv has become one of the most widely used non market valuation techniques cv s prominence is due to its flexibility and ability to estimate total value including passive use value its use and the inclusion of passive use value in benefit cost analyses and environ mental litigation are the subject of a contentious debate this paper discusses key areas of the debate over cv and the validity of passive use value we conclude that many of the alleged problems with cv can be resolved by careful study design and implementation we further conclude that claims that empirical cv findings are theoretically inconsistent are not generally supported by the literature the debate over cv however has clarified several key issues related to nonmarket valuation and can provide useful guidance both to cv practitioners and the users of cv results

on visible choice sets and scope sensitivity abstract in this paper we argue that the burgeoning empirical debate over scope sensitivity within contingent valuation studies is fundamentally incomplete in that it has neglected a systematic examination of certain effects of study design upon observed scope sensitivity in particular we highlight the fact that in certain study designs the choice set initially offered or visible to respondents is changed in a stepwise manner as they progress through a valuation exercise while other designs involve advance disclosure regarding the full extent of the final visible choice set prior to any choices or values being elicited the issue of changes in the visible choice set is alluded to by smith j environ econom manage 22 1 71 who identifies this as a primary challenge to kahneman and knetsch s j environ econom manage 22 1 57 well known experimental results kahneman and knetsch contend that it seems highly implausible that this minor procedural change would significantly alter results p 61 but do not test this assertion we present experimental and field tests of the impact upon contingent values of varying the visible choice set through stepwise and advance disclosure these dimensions of design are interacted with changes in the order in which nested goods are presented bottom up versus top down when a stepwise disclosure procedure is adopted the observed scope sensitivity is substantially and significantly affected by the order in which goods are presented but such procedural variance is not observed within advance disclosure designs conjectures regarding the origin and implications of such findings are presented

from voluntarism to regulation a study on ownership economic performance and corporate environmental information disclosure in china this article examines whether economic performance could affect eid and how the relationship is determined by the form of ownership from voluntarism to regulation under the current chinese context in this study our empirical results show that the relationship between firms performance and eid is complex and the interactive impact of ownership and economic performance on eid significantly varies from voluntary disclosure to mandatory disclosure this study provides a more comprehensive understanding of the motivations in corporate eid the performance impression theory can be used to explain the disclosure behaviors during the period of voluntary disclosure while the pressure legitimacy theory can be used during the period of mandatory disclosure the finding suggests that when evaluating corporate eid associated with economic performance in emerging economies such as china it needs to be cautious as which tends to vary with the form of ownership and whether there is any mandatory regulation in place

adequate responsiveness to scope in contingent valuation the standard test for scope sensitivity in contingent valuation studies determines whether the response to changes in scope is statistically significant it does not address whether the magnitude of response is appropriate given the specified changes in scope we examine contingent valuation studies that implemented scope tests to determine what they imply about the adequacy of response to scope we find that in the vast majority of studies the magnitude of response cannot be assessed only three studies permit such an assessment samples and hollyer 1990 diamond et al 1993 and chapman et al 2009 the first two papers find that responses to their surveys did not vary adequately with scope the third study passed the standard scope test but we show that the magnitude of response in this study is inadequate by straightforward methods of assessment and cannot be explained by diminishing marginal utility or substitution more research is needed on this issue including wider application of adding up tests on incremental parts as well as the development of other methods that permit an assessment of the magnitude of response or other tests of rationality

economies of scope in endangered species protection evidence from interest group behavior abstract this paper looks for positive spillovers from the legal protection of one species to the welfare of others and for evidence of economies of scope in the costs associated with protecting species under the endangered species act the analysis uses data on the intensity of interest group comment activity in response to proposals to protect new species the results suggest that these phenomena are significant strengthening arguments that wildlife protection policy should be shifted toward species groups or ecosystems however the findings are also consistent with diminishing public willingness to pay for protected species in a given area a pattern which also has public policy implications

an adding up test on contingent valuations of river and lake quality for a contingent valuation cv study of a bundle of water quality improvements this paper tests whether the sum of the estimated willingness to pay wtp for each individual part of the package evaluated incrementally equals the estimated wtp for the entire bundle as implied by standard utility theory this is the first application of the adding up test using incremental parts and carson and groves s 2007 procedures to induce truthful respondents answers the test is failed which implies that either the cv method did not elicit truthful answers or that respondents true preferences are inconsistent with standard utility theory

incentive effects of workers compensation insurance abstract this paper uses micro level data from the current population survey to estimate the determinants of participation in state workers compensation programs in the united states the principal finding is that higher workers compensation benefits are associated with greater participation in the workers compensation program after accounting for a variety of covariates in addition the waiting period is found to have a substantial negative effect on program participation finally time series estimates based on the cross sectional model show that the growth in workers compensation claims in the 1970s corresponds reasonably well with the growth in real benefits in this time period

workers compensation moral hazard and the composition of workplace injuries this paper provides evidence that workers compensation insurance wc affects not only the occurrence but also the composition of reported injuries in our theoretical approach wc is the source of two interrelated moral hazard problems underprovision of accident preventing efforts by the insured worker ex ante moral hazard and false reporting of injuries ex post moral hazard our model predicts that under certain assumptions the impact of wc benefits is stronger on the probability of reporting a difficult to diagnose injury than on the probability of reporting an injury that is easy to diagnose panel data on 9 800 workers in the quebec construction industry over each month of the period 1977 86 combining administrative data from the quebec construction board with data from the quebec workers compensation board are used for the estimates the parameters of the model are estimated using a threealternative logit kernel hybrid multinomial probit mnp framework with individual random effects our results confirm our theoretical pre

unemployment insurance and the duration of workplace accidents the social cost of workplace accidents is large in a typical year in the united states from one third to one half as many working days are lost to work injuries as are lost to unemployment see krueger 1988 recently economists have paid more attention to the economic issues involved in occupational safety and health osh in particular they have investigated the different effects of government intervention in this area for example it has been found that in general safety regulations and their enforcement had little impact on the incidence of workplace accidents there also seems to be a consensus that an increase in the generosity of workers compensation wc benefits is associated with an increase in both the frequency and the duration of wc claims for workplace accidents in this connection some researchers have raised a potentially important issue the possibility of substitution between wc and unemployment insurance ui in most countries wc is more generous than ui in terms of wage replacement and there may therefore be an incentive for workers about to be laid off to try to benefit from wc instead of ul2 workers suffering from a workplace accident may also be tempted to take action in order to obtain a longer period of recovery compensated by wc these two types of moral hazard are likely to be particularly important when injuries are hard todiagnose e g low back injuries and in industries where the level of unemployment is such that many workers may expect to be unemployed and to receive ui benefits after their recovery the construction industry in canada may be considered such an industry since climate constraints mean that many workers are unemployed during winter time fortin and lanoie 1992 were the first authors to investigate these issues in particular from quebec aggregate data at the industry level they found

corporate social responsibility and crony capitalism in taiwan corporate social responsibility csr has become increasingly popular in advanced economies in the west in contrast csr awareness in asia is rather low both on the corporate and state level however recent events have shown that the csr is receiving more attention by corporations in asia recent development in csr in taiwan is one example of such a trend a 2005 survey on the 700 publicly listed companies in taiwan on csr has highlighted the current csr situation concurrently the numbers of corporate scandals and corruption have dramatically increased over the past 6 years corporate csr activities co existing with pervasive corporate scandals create a phenomenon of contradictions this article aims to report via the survey findings the current development of business ethics in corporate taiwan and to interpret the findings in context of taiwan s business ethos especially its confucian familism and crony capitalism

player and referee roles held jointly the effect of state ownership on china s regulatory enforcement against fraud this article examines the impact of the prevailing state ownership in the chinese stock market on corporate governance and the financial regulatory system respectively as the internal and external monitoring mechanisms to deter corporate fraud and protect investors in line with the literature that state ownership exaggerates the agency problem we find that the retained state ownership in privatised firms increases the incidence of regulatory enforcements against fraud for the state owned enterprises soes however larger state ownership is associated with a lower incidence of enforcement actions this is attributed to the mutual political affiliation of the fraudulent soes and the regulatory commission a new regulation solutions for listed firm checks promulgated in march 2001 has mitigated this effect by empowering the regulatory commission to increase the severity of regulatory conditions our evidence confirms the improvement in the regulatory environment and investor protection in the chinese stock market brought about by the regulatory reform and development

how does environmental corporate social responsibility matter in a dysfunctional institutional environment evidence from china drawing on institutional and signaling theories this study examines how environmental corporate social responsibility ecsr affects firm performance in a dysfunctional institutional environment we extend the ecsr literature by suggesting that ecsr indirectly influences firm performance through the mediating effects of business and political legitimacy based on a dataset of 238 firms in china we find that ecsr affects business and political legitimacy followed by firm performance moreover legal incompleteness weakens and legal inefficiency strengthens the effects of ecsr on business and political legitimacy

workers compensation and moral hazard two types of moral hazard have been determined the first type is related to self prevention activities affecting probabilities of accidents the second type relates to the agent s activities whenever the accident occurs the authors objective consists of presenting an empirical measure of the significance of this second type of moral hazard in the workers compensation market the main challenge in isolating moral hazard consists of dividing into two parts the total variation in recovery time with respect to changes in insurance coverage 1 the variation of consumption corresponding to a given level of information and 2 the variation of consumption due to greater asymmetrical information the methodology used in this study separates these two variations copyright 1991 by mit press

existence values in benefit cost analysis and damage assessment existence values for obscure resources should not be ruled out a priori because consumers have limited time and resources for information gathering furthermore to the extent that environmental good things are highly substitutable existence values must be cautiously interpreted when evaluating public choice alternatives but similar concerns do not arise in damage assessments issues associated with adding up existence values across resources high per unit values and property rights in the existence of resources are also addressed

the effectiveness of public enforcement evidence from the resolution of tunneling in china this paper examines the effectiveness of public enforcement by studying the effects of regulatory intervention to curb tunneling through intercorporate loans in china specifically we explore whether public enforcement efforts in 2006 blacklisting and sanctions resulted in less tunneling and ultimately in increased performance for tunneling firms we show that tunneling is among the dominant factors increasing the likelihood of becoming blacklisted we also find that firms tunneling mechanisms decreased significantly after the regulatory shock and that their performance increased significantly compared to non tunneling firms after the regulatory shock finally we find a positive market reaction to the public announcement of tunneling both for firms that have been blacklisted and other tunneling firms that are not blacklisted collectively these results suggest that public enforcement in the presence of a credible threat succeeds in deterring the effect on tunneling behavior in china

mutual fund activism and market regulation during the pre ifrs period the case of earnings informativeness in china from an ethical perspective this paper investigates the emerging effect of mutual fund involvement on the agency problem between majority and minority shareholders during the pre ifrs period in china indicated by earnings informativeness from an ethical perspective we find that the presence of mutual fund hampers earnings informativeness implying that mutual funds in general at their early stage in china are not yet capable of serving as an effective monitor this finding is in sharp contrast to the role of institutional investors in mature markets as documented in the literature however mutual funds affiliated with banks have been found to be effective to improve earnings informativeness of chinese listed companies and the impact is more pronounced among those affiliated with joint equity banks compared to their counterparts affiliated with state owned banks

workers compensation rate regulation how price controls increase costs abstract in the 1980s regulation constrained workers compensation insurance premiums in the face of rapid growth in loss costs we develop and test the hypothesis that rate suppression exacerbates loss growth leading to higher losses and premiums the empirical analysis using rating class data for eight states for the period 1985 91 confirms that rate suppression measured by lagged residual market share of payroll increased loss growth the cost increasing effects are greater in the residual market than in the voluntary market but premiums increased more rapidly in the voluntary market the resulting pattern of cross subsidies between and within classes is consistent with a simple model of political influence with subsidies to high risks and small firms at the expense of low risks and insurer equity

testing the internal consistency of contingent valuation surveys abstract for an internal consistency check one can examine wtp responses to different surveys holding an environmental problem constant concave preferences imply wtpconcavein the success of a remedy the same preferences imply wtpconvexin the magnitude of an environmental problem assuming a successful remedy having opposite signed curvature of these two wtp patterns is general not requiring concave preferences for an adding up test an environmental commodity can be divided then wtp for one part plus wtp for the second part conditional on already having the first part equals wtp for the whole adjusted by an income effect

test retest reliability of the contingent valuation method a comparison of general population and visitor responses the reliability of the contingent valuation method is evaluated by resurveying the same general households and visitors nine months after their original survey test retest correlations on willingness to pay are statistically significant and ranged from 422 for the general population sample to 782 for the visitor sample using a paired t test there was no statistical difference between an individual s first and second reported willingness to pay chow tests comparing the original and resurvey willingness to pay functions showed no statistical difference at the 01 level reported willingness to pay is reasonably stable over the time period surveyed

the case for diminishing marginal existence values abstract this study addresses the debate over sensitivity of existence values measured by contingent valuation to scope tests we reconcile much of the debate within one theoretical model if marginal wtp for existence goods is diminishing then a study that tested for sensitivity to scope over a range for which marginal wtp is high would be more likely to detect sensitivity to scope than a study that focused on a range for which marginal wtp is much lower an empirical model demonstrates this point for existence value of remote wilderness parks these results have significant implications for future contingent valuation work

exploring welfare implications of resource equivalency analysis in natural resource damage assessments abstract resource equivalency analysis rea has become the dominant method for calculating natural resource damages for biological injuries from pollution incidents this methodology compares resources lost as a result of an incident to benefits that can be gained from a habitat or wildlife restoration project compensation is evaluated in terms of resource services instead of market currency recently this approach has been questioned regarding its ability to provide adequate compensation based on economic welfare principles the following paper examines these critiques and develops a model to quantify the welfare implications of using rea when some of its implicit assumptions are violated we focus on the situation where compensatory restoration projects provide services that are comparable to those lost as a result of an incident we examine simulation scenarios where the public has heterogeneous preferences for resources and where resource values change over time using the hicks kaldor criterion we find that the traditional rea provides an acceptable approximation of aggregate compensation for a reasonably wide range of economic and biological parameter combinations

rate regulation safety incentives and loss growth in workers compensation insurance we analyze the relationship between insurance rate regulation inflationary cost surges and incentives for loss control using state level data on workers compensation insurance for 24 states during 1984 90 regulators often responded to rapid loss growth during this period by denying rate increases or approving increases that were less than initially requested by insurers we test whether rate suppression increased loss growth by distorting incentives for loss control our regressions indicate a positive and statistically reliable relationship between loss growth and lagged measures of regulatory price constraints suggesting that rate regulation increased the frequency and or severity of employee injuries copyright 2000 by university of chicago press
