models for referendum data the structure of discrete choice models for contingent valuation abstract in 1979 bishop and heberlein introduced an appealing variant of the contingent valuation method which required only yes or no responses hanemann developed a utility theoretic interpretation of the yes no responses which has helped popularize the approach recently cameron has offered another interpretation also utility theoretic which she argues is more general than the hanemann random utility model this paper compares the deterministic models suggested by hanemann and cameron showing them to be dual to each other it shows that correct specification of either function must exclude endogenous variables such as quantity demanded it also demonstrates that using utility theoretic models allows one to compare travel cost models and contigent valuation models on the basis of their implied behavior not on the unobservable surplus or variation measure

the value of tax shields is not equal to the present value of tax shields abstract the value of tax shields is the difference between the present values of two different cash flows each with their own risk the present value of taxes for the unlevered company and the present value of taxes for the levered company for constant growth companies the value of tax shields in a world with no leverage cost is the present value of the debt times the tax rate times the unlevered cost of equity discounted at the unlevered cost of equity this result arises as the difference of two present values and does not mean that the appropriate discount for tax shields is the unlevered cost of equity

correcting for the endogeneity of pro environment behavioral choices in contingent valuation abstract in contingent valuation studies observed behavioral choices often enter as independent variables in the willingness to pay function however these variables may be endogenously determined when the error term in the behavioral model is correlated with the error term in the willingness to pay model we investigate the effects of correcting for the endogeneity of a variable namely membership status in environmental organizations that proxies unobservable characteristics of the respondents jointly modeling the membership variable and the willingness to pay response yields an estimate for the effect of the former that contradicts previous findings but is intuitive and agrees with theoretical expectations

a joint investigation of public support and public values case of instream flows in new mexico abstract instream flow can be defined as the flow of water in its natural channels without diversion alone among the western us states new mexico nm fails to provide any mechanism for the protection of instream flows and has a long history of political resistance to any change in the status quo using the combined results from two statewide telephone surveys this study jointly investigates stated voting preferences for a proposed institutional change and stated valuation preferences for minimum instream flow protection the contingent valuation cv question uses a dichotomous choice dc elicitation format and a voluntary contribution trust fund payment vehicle results show a highly significant positive correlation between expressed voting preferences and expressed valuation preferences additionally those individuals who respond yes to the voting question have an expected willingness to pay wtp of 80 with a 95 confidence interval ci that is always positive 62 97 while those who respond no to the voting question have an expected wtp that is actually slightly negative 6 with a 95 ci containing zero 14 2 taken together these results provide evidence of construct validity estimation results are also shown to be temporally reliable across repeated samples thus there is strong evidence of public support for instream flow protection and its associated nonmarket benefits such evidence helps to provide instream flow concerns with standing in future nm water policy debates prominent examples include explicitly defining beneficial use and public welfare to allow consideration of instream flow protection

semi nonparametric distribution free dichotomous choice contingent valuation abstract we apply a semi nonparametric distribution free estimator for binary discrete response data to the estimation of a dichotomous choice contingent valuation model using this estimator mean and median compensating and equivalent variation can be consistently estimated without making nontheoretically motivated assumptions on consumer preferences the approach is illustrated using a contingent valuation survey of willingness to pay for reduction of risk of premature death due to exposure to hazardous waste we find that a conventional parametric estimator and the proposed estimator give similar estimates of unconditional wtp but that conditional on explanatory variables the estimates are quite different

study on benefit transfer in an international setting how to improve welfare estimates in the case of the countries income heterogeneity abstract the paper aims at investigating the validity of benefit transfer in the case of transfers between countries highly heterogeneous in income and demonstrates relative performance of different benefit transfer methods under these conditions lake water quality valuation studies were conducted in two countries in transition poland and the czech republic they reflected two earlier studies carried out in norway we examine how income elasticity of wtp varies with the levels of income and find support for applying the income elasticity of 1 to adjust transferred welfare estimates in case of high differences in income between countries in addition we show that using site specific measures of income outperforms transfers based on gpd per capita the accuracy of benefit transfer is compared using equivalence testing following the tosc two one sided convolutions test a new more informative way of reporting equivalence is proposed based on computing minimum tolerance level rather than specifying it a priori

treatment of don t know responses in contingent valuation surveys a random valuation model abstract this paper provides a utility theoretic interpretation of don t know dk responses in contingent valuation surveys using a referendum elicitation procedure the random valuation model in this paper assumes that each respondent of a contingent valuation survey has an implicit valuation distribution rather than a single true value as traditionally assumed in his her mind if an offered referendum bid is not clearly different from the mean value of one s valuation distribution the respondent may give a dk answer to the cv referendum question based on this model a maximum likelihood procedure is proposed for estimating respondents willingness to pay for a nonmarket good with referendum contingent valuation data which include dk responses an empirical illustration of this estimation procedure is also provided

do reminders of substitutes and budget constraints influence contingent valuation estimates a test is performed of the recommendation by the noaa panel on contingent valuation that respondents be reminded about other substitute resources and their budget constraint prior to answering the willingness to pay wtp question the context for this experiment is a cvm study of the benefits from reducing fire hazards to old growth forests in oregon the test was performed using two mail surveys that were otherwise identical except for the inclusion of reminder statements prior to the wtp question the dichotomous choice logit equations were not statistically different between versions and the mean wtp results were identical

using labels to investigate scope effects in stated preference methods insufficient sensitivity to scope variations in the scale of the environmental good on offer remains a major criticism of stated preference methods and many studies fail a scope test of some sort across a range of existing explanations for insensitivity to scope commodity mis specification embedding warm glows there seems to exist no clear conclusion on how to deal with the problem this paper provides an alternative explanation for insufficient sensitivity to scope based on re definition of the determinants of value for environmental goods within an attributes based choice model in the proposed framework respondents willingness to pay need depend not only on physical characteristics of a good but may also depend on the label under which the environmental good is sold in the hypothetical market to investigate this problem a choice experiment study of biodiversity was conducted we find that controlling for the effects of a label in this case national park designation leads to significant increase in the scope sensitivity of welfare measures

a satisfactory benefit cost indicator from contingent valuation abstract standard economic concepts are used to develop a model of individual behavior when subject to the constraints of the contingent valuation choice context the model yields refutable consequences that are consistent with previously reported empirical findings including some that have been thought to be anomalous the model is used to show that different contingent valuation formats have predictably different performance characteristics notably the hicksian compensating measures are satisfactory benefit cost indicators when elicited using any one of several formats identified in the text of the formats examined one form of a policy referendum appears to have the most satisfactory characteristics overall we conclude that contingent valuation is a progressing research program

public support for reducing us reliance on fossil fuels investigating household willingness to pay for energy research and development abstract in order to reduce future dependence on foreign oil and emissions of co2 how much would us households be willing to pay annually to support increased energy research and development r d activities designed to replace fossil fuels does it matter whether the r d includes nuclear energy options we explore these questions using data from a unique set of national telephone and internet surveys using a national advisory referendum format the contingent valuation method is applied to estimate annual household willingness to pay wtp for us household support of a national energy research and development fund erdf for investments in energy sources not reliant on fossil fuels while accounting for the level of un certainty in voting responses the wtp modeling includes a comparison of both classic maximum likelihood estimation mle and bayesian analysis evidence indicates that mle and bayesian analysis achieve similar statistical inference while the bayesian analysis provides a narrower confidence interval around estimated wtp

a randomized response approach to dichotomous choice contingent valuation in this paper we combine dichotomous choice contingent valuation dc cv with the randomized response rr method for asking sensitive survey questions rr increases respondents anonymity by allowing them to answer a sensitive question without revealing with certainty their true response we combine rr with dc cv to test for response effects in the valuation of a public good in a setting of expected social pressure while there are practical implementation issues our findings suggest that the rr technique is a useful tool for exploring social context effects rather than generalize from our pre test results we instead emphasize the development of the experimental technique

specification of the logit model the case of valuation of nonmarket goods abstract we address the proper specification of the logit model for estimation of nonmarket commodity demand economic theory is used to show the conditions which must be met by the logit functional form if it is to yield valid estimates of welfare change measures and demand relationships an empirical example is used to illustrate the argument recreational boating data were collected using the contingent valuation method cvm in texas in one instance the demand curve is positively sloped due to the specific functional form chosen the estimated demand curve for the theoretically preferred functional form has the expected negative slope

a perspective on regional and global strategies of multinational enterprises multinational enterprises mnes are the key drivers of globalization as they foster increased economic interdependence among national markets the ultimate test to assess whether these mnes are global themselves is their actual penetration level of markets across the globe especially in the broad triad markets of nafta the european union and asia yet data on the activities of the 500 largest mnes reveal that very few are successful globally for 320 of the 380 firms for which geographic sales data are available an average of 80 3 of total sales are in their home region of the triad this means that many of the world s largest firms are not global but regionally based in terms of breadth and depth of market coverage globalization in terms of a balanced geographic distribution of sales across the triad thus reflects a special and rather unusual outcome of doing international business ib the regional concentration of sales has important implications for various strands of mainstream ib research as well as for the broader managerial debate on the design of optimal strategies and governance structures for mnes journal of international business studies 2004 35 3 18 doi 10 1057 palgrave jibs 8400073

rational herding in financial economics abstract this paper briefly describes recent papers on the economics of rational herding in financial markets some models can predict perfect herding in which rational agents all act alike without any countervailing force such herding typically arises either from direct payoff externalities negative externalities in bank runs positive externalities in the generation of trading liquidity or in information acquisition principal agent problems based on managerial desire to protect or signal reputation or informational learning cascades the paper also provides a few pointers to related literature and suggests issues to be addressed in future research

the asian financial crisis the role of derivative securities trading and foreign investors in korea abstract this paper is part of a larger research program pertaining to the role of derivatives during financial crisis and also part of the research pertaining to the causes of the asian financial crisis the korean market is studied because of two reasons 1 it is an important example of the asian financial meltdown and 2 there is a detailed data set available of all transactions by different types of protagonists including foreign investors the results in this paper indicate that futures markets and trading by foreign investors played a key role during the korean stock market turbulence in 1997

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

the role of uncertainty in the relationship between fairness evaluations and willingness to pay participants in contingent valuation studies may be uncertain about a number of aspects of the policy and survey context the uncertainty management model of fairness judgments states that individuals will evaluate a policy in terms of its fairness when they do not know whether they can trust the relevant managing authority or experience uncertainty due to insufficient knowledge of the general issues surrounding the environmental policy similarly some researchers have suggested that not knowing how to answer wtp questions participants convey their general attitudes toward the public good rather than report well defined economic preferences these contentions were investigated in a sample of 840 residents in four urban catchments across australia who were interviewed about their wtp for stormwater pollution abatement four sources of uncertainty were measured amount of prior issue related thought trustworthiness of the water authority insufficient scenario information and wtp response uncertainty a logistic regression model was estimated in each subsample to test the main effects of the uncertainty sources on wtp as well as their interaction with fairness and proenvironmental attitudes results indicated support for the uncertainty management model in only one of the four samples similarly proenvironmental attitudes interacted rarely with uncertainty to a significant level and in ways that were more complex than hypothesised it was concluded that uncertain individuals were generally not more likely than other participants to draw on either fairness evaluations or proenvironmental attitudes when making decisions about paying for stormwater pollution abatement

speculation in international crises report from the gulf recent years have seen recurring international financial crises as well as a tremendous rise in trading and speculation how are the two related are speculators and trading responsible for market volatility this paper presents a study of the gulf crisis of 1990 1991 examining the behavior of the international oil market during a period of unprecedented volatility the analysis suggests that a combination of political events and market fundamentals rather than trading was behind this volatility

disentangling preferences and expectations in stated preference analysis with respondent uncertainty the case of invasive species prevention abstract contingent valuation typically involves presenting the respondent with a choice to pay for a program intended to improve future outcomes such as a program to place parcels into conservation easement or a program to manage an invasive species deducing from these data the value of the good or bad at the core of the program the welfare gain generated by a parcel of conserved land for instance or the loss incurred by a species invasion often is not possible because respondent preferences are conflated with their expectations about future environmental outcomes in the absence of the program this paper formally demonstrates this conundrum in the context of a standard contingent valuation survey and examines the use of additional survey data to resolve it the application is to the prevention of lake invasions by eurasian watermilfoil myriophyllum spicatum an invasive aquatic plant that is present in many lakes in the northern u s and canada and a possible threat to many more respondents are shoreline property owners on lakes without eurasian watermilfoil the estimated per property welfare loss of a lake invasion is 30 550 for one model and 23 614 for another both of which are in reasonable agreement with estimates obtained from a recent hedonic analysis of eurasian watermilfoil invasions in the study area 16 and from a companion contingent valuation survey of shoreline property owners on already invaded lakes

explaining crude oil prices using fundamental measures abstract oil is the world s most important commodity and improving the understanding of drivers of its price is a longstanding research objective this article analyses real oil prices during 1984 2007 using a monthly dataset of fundamental and market parameters that cover financial markets global economic growth demand and supply of oil and geopolitical measures the innovation is to incorporate proxies for speculative and terrorist activity and dummies for major industry events and quantify price impacts of each new findings are positive links between oil prices and speculative activity bond yields an interaction term incorporating opec market share and oecd import dependence and the number of us troops and frequency of terrorist attacks in the middle east shocks also prove significant with a 6 18 per barrel impact on price for several months

alternative approaches for incorporating respondent uncertainty when estimating willingness to pay the case of the mexican spotted owl abstract this paper explores the sources and patterns of respondents uncertainty regarding their willingness to pay wtp and presents alternative approaches for incorporating this uncertainty into estimation of the logit model recently proposed approaches are compared to methods proposed in this paper which allows for incorporation of uncertainty regarding both yes and no responses these approaches are evaluated by comparing the goodness of fit and variability of mean wtp extreme recoding of uncertain yes responses as no responses reduces the logit goodness of fit and the precision of the wtp estimate incorporating the degree of uncertainty of yes responses results in the highest goodness of fit and the smallest variability of mean wtp among the various models addressing uncertainty a regression model is used to determine the significant determinants of respondent uncertainty

the net benefit of saving the asian elephant a policy and contingent valuation study reports results from a contingent valuation cv survey of willingness to pay wtp for the conservation of the asian elephant of a sample of urban residents living in three selected housing schemes in colombo the capital of sri lanka face to face surveys were conducted using an interview schedule is a non linear logit regression model is used to analyse the respondents responses for the payment principle questions and to identify the factors that influence their responses we investigate whether urban residents wtp for the conservation of elephants is sufficient to compensate farmers for the damage caused by elephants we find that the beneficiaries the urban residents could compensate losers the fanners in the areas affected by human elephant conflict hec and be better off than in the absence of elephants in sri lanka therefore there is a strong economic case for the conservation of the wild elephant population in sri lanka however we have insufficient data to determine the optimal level of this elephant population in the kaldor hicks sense nevertheless the current population of elephant in sri lanka is kaldor hicks preferable to having none c 2003 elsevier b v all rights reserved

institutions sans frontieres international agreements and foreign investment we examine whether the presence of international investment agreements iias negotiated among countries for foreign investor protection lowers political risk faced by multinational enterprises mnes drawing on research from international business political science and international law we argue that iias increase expected future cash flows and hence the value of foreign assets by limiting the ability of host governments to make discriminatory policy changes however the need for iia protection and the ability to benefit from it varies with firm characteristics using detailed transaction level data for sale of petroleum assets in 45 countries we find that mnes pay significantly higher amounts for those protected by iias than similar but unprotected assets an effect moderated by the firm s reserve size and state ownership

the dax and the dollar the economic exchange rate exposure of german corporations this paper examines the economic exposure of german corporations to changes in the dm us dollar exchange rate our work contributes to the existing body of literature in the following ways firstly we point out conceptual problems of previous attempts to estimate economic exposure secondly we find that german firms are significantly exposed to changes in the dm us dollar rate however our results are unstable over time

a multistage linear stochastic programming model for optimal corporate debt management abstract large corporations fund their capital and operational expenses by issuing bonds with a variety of indexations denominations maturities and amortization schedules we propose a multistage linear stochastic programming model that optimizes bond issuance by minimizing the mean funding cost while keeping leverage under control and insolvency risk at an acceptable level the funding requirements are determined by a fixed investment schedule with uncertain cash flows candidate bonds are described in a detailed and realistic manner a specific scenario tree structure guarantees computational tractability even for long horizon problems based on a simplified example we present a sensitivity analysis of the first stage solution and the stochastic efficient frontier of the mean risk trade off a realistic exercise stresses the importance of controlling leverage based on the proposed model a financial planning tool has been implemented and deployed for brazilian oil company petrobras

price discovery in oil markets a time varying analysis of the 1990 1991 gulf conflict abstract this study examines the behaviour of crude oil spot and futures markets in the uk and usa during the 1990 1991 gulf conflict the objective is to investigate the relative ability of spot and futures markets to impound information this is achieved with the use of a generalized model of price discovery which represents a synthesis of the two most commonly used methodologies in its field emphasis is placed on the time varying nature of price discovery relationships results indicate that such relationships are strongly temporal these findings offer new insights into the nature of relationships between spot and futures markets

actual averting expenditure versus stated willingness to pay the purpose of this study is to perform a complete comparison of actual averting expenditure and stated willingness to pay measures and to determine if the averting expenditure is a lower bound of the willingness to pay measured from contingent valuation experiment as suggested by literature in addition to the single value comparison bootstrap krinsky and robb jackknife and cameron are four simulation methods used to calculate confidence intervals for response function sample sizes of 100 200 and 1000 are simulated 100 and 200 times respectively a set of data with 540 households from a contingent policy referendum survey is employed for our purpose under a specific level of bod improvement a one to one single mean value comparison of the actual averting expenditure is greater than the mean willingness to pay from utility difference model the empirical results are consistent with the theoretical expectation for expenditure difference that averting expenditure is a lower bound of willingness to

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

recovering an asset s implied pdf from option prices an application to crude oil during the gulf crisis we develop a general method for estimating the implied martingale equivalent probability density function pdf for futures prices from american options prices the early exercise feature of american options precludes expressing the price of the option in terms of the pdf there exist tight bounds for the price of american options in terms of the pdf we demonstrate how these bounds together with observed option prices can be used to estimate the parameters of the pdf we estimate the distribution for crude oil during the persian gulf crisis and find the distribution differs significantly from that recovered using standard techniques

international listings of stocks the case of canada and the u s the globalization of financial markets has seen ever increasing numbers of firms choosing to list their stocks on foreign exchanges we examine whether the extent of economic and financial market integration or segmentation between a firm s home country and listing country influences stock price reaction by examining the case of two similar countries the u s and canada during the 100 days before the week of interlisting in the u s risk adjusted stock prices of canadian firms rise on average by over 9 4 rise by an additional 2 around the interlisting date but follow with a corresponding drop of 9 7 in the 100 days after interlisting we interpret this evidence to be consistent with the financial market segmentation between canada and the u s however a subsample of canadian resource firms does not exhibit these stock price effects suggesting industry related factors may also be an important determinant of integration we also find average trading volume in interlisted stocks more than doubles in the months following interlisting

language related differences in a contingent valuation study english versus spanish to test the similarity of english and spanish speaking households responses to a contingent valuation survey phone interviews were conducted in both languages regarding two forest fire prevention programs while there were similar response rates there were significant differences in the most frequent reasons given for refusing to pay in the pooled logit model the language intercept and bid interaction variables were insignificant in both programs the likelihood ratio test of separate logit equations showed no statistical difference between english and spanish speaking households responses to either program mean benefits reported by spanish speaking households were about one third lower than english speaking households although the difference is not statistically significant according to the 1990 census more than 32 million adults in the united states speak a language other than english in their home and these multiracial populations are growing faster than the english speaking population in many states according the bureau of census from 1990 to 1999 the hispanic population grew by 39 in the united states in states such as arizona california florida and texas hispanics are a large and rapidly growing segment of the population many in the hispanic population either do not speak english or are more fluent in spanish than in english executive order 12898 by president clinton requires federal agencies to evaluate environmental justice of federal actions on minority populations under this executive order policy makers are charged with the daunting

firm strategy and economic exposure to foreign exchange rate movements this study examines the implications of differences in strategy and industry structure for firms economic exposures to foreign exchange rate movements in contrast with previous research using a single currency proxy this study estimates firms exposures using a multiple currency model the empirical evidence from u s manufacturing firms indicates that 13 to 17 percent of firms are exposed to foreign exchange rate movements results from cross sectional analyses reveal that foreign direct investment reduces economic exposure to foreign exchange rate movements

is the international business research agenda running out of steam this research note challenges international business researchers to think of their future work in terms of the past achievements of their discipline it identifies three key research areas corresponding to attempts to tackle crucial empirical questions the explanation of foreign direct investment the multinational firm and the globalization of business it ends by considering the future research agenda

semiglobalization and international business strategy if markets were either completely isolated by or integrated across borders there would be little room for international business strategy to have content distinctive from mainstream strategy but a review of the economic evidence about the international integration of markets indicates that we fall in between these extremes into a state of incomplete cross border integration that i refer to as semiglobalization more specifically most measures of market integration have scaled new heights in the last few decades but still fall far short of economic theory s ideal of perfect integration the diagnosis of semiglobalization does more than just supply a relatively stable frame of reference for thinking about the environment of cross border operations it also calls attention to the critical role of location specificity in the prospects of distinctive content for international business strategy relative to mainstream business and corporate strategy in addition it flags factors products subject to location specificity as being salient from the perspective of international business finally it highlights the scope for strategies that strive to capitalize on the large residual barriers to cross border integration as well as those that simply try to cope with them

government intervention in the venezuelan petroleum industry an empirical investigation of political risk two important aspects of political risk analysis that have not received much attention in the literature are a the reasons why multinational firms experience different types of intervention and b the timing of intervention in order to address these issues this research develops a conceptual model of political risk based on the premise that host government intervention is related to specific objectives of the government vis a vis multinational firms information reflecting the attainment of objectives motivates the government to intervene in a given manner the application of this model to the case of the venezuelan petroleum industry from years 1947 to 1976 provides some support for this model and gives insight into the timing of specific types of intervention

flexible exchange rates prices and the role of news lessons from the 1970s recent experience with flexible exchange rate systems has led to renewed interest in the operation of foreign exchange markets as reflected in many recent studies of the principal determinants of exchange rates the 1970s witnessed the dramatic alteration of the international monetary system from a regime of pegged exchange rates which prevailed for about a quarter of a century since the bretton woods conference into a regime of flexible though managed rates as a consequence of the emergence of the new legal and economic system traders national governments and international organisations were confronted with new economic problems choices and instruments during the 1970s ex change rates fluctuated widely and inflation rates accelerated the international monetary system had to accommodate extraordinarily large oil related shocks which affected trade flows in goods and assets huge oil payments had to be recycled uncertainties concerning future developments in international politics reached new heights and the prospects for the world economy got gloomier these developments placed unprecedented pressures on the markets for foreign exchange as well as on other asset markets they were associated with a large slide in the value of the us dollar and resulted in speeding up the creation of new institutions like the european monetary system which provided the formal framework for the management of exchange rates among members

how people respond to contingent valuation questions a verbal protocol analysis of willingness to pay for an environmental regulation abstract this paper investigates what a respondent is thinking when answering a willingness to pay question in a contingent valuation using a think aloud technique from psychology called verbal protocol analysis the willingness to pay responses we observed seem to be constructed from a variety of considerations including an obligation to pay a fair share of the cost of the solution and signaling concern for a larger set of environmental issues the finding that respondents seem to construct their values at the time they are asked rather than reporting a more well defined value is seen as consistent with over two decades of research on the psychology of decision making potential uses of verbal protocols in contingent valuation studies are also discussed

corporate debt management and the value of the firm three alternative characterizations of corporate debt management policy which have had wide currency in the literature are examined they are shown to give rise to substantial differences in their predictions of total firm value this study concludes that of the three the one that assumes that management periodically rebalances the firm s debt levels in response to evolving new information on expected future operating cash flows is the most logically consistent on that basis a reinterpretation of the available empirical evidence on the tax effect of debt is indicated

default market microstructure and changing trade patterns in forward markets a case study of north sea oil abstract default or credit risk is a central difference between forward and futures markets empirical tests have found little difference between forwards and futures prices but these tests have been conducted on markets where such risk is minimal e g foreign exchange so that even if default risk is in general an important difference between forward and futures trading they would have been unable to detect its effects in contrast this paper presents a case study of a market for forward delivery of a type of crude oil from the north sea that experienced widespread and well documented defaults when the spot price of the underlying commodity plunged from roughly 30 to roughly 10 per barrel in a short period of time in early 1986 the defaults were by relatively small lightly capitalized trading companies firms that neither produce nor consume the physical commodity because information on defaults in financial markets is scarce the paper describes the circumstances surrounding the default episode in some detail the market survived the default episode with market microstructure unaltered and still flourishes despite the successful introduction of a futures market in the same commodity by the london international petroleum exchange patterns of trade changed however the paper examines the hypothesis that investment banks which entered the market following the default period provided intermediation services to market participants thereby substituting to an extent for a clearinghouse taking advantage of the information on the buyer and seller in each transaction the paper presents nonparametric tests for changing patterns of forward trade

tough and easy choices testing the influence of utility difference on stated certainty in choice in choice experiments respondents in stated preference studies may be uncertain about their preferences for the good presented to them inspired by wang j environ econ manag 32 219 232 1997 we hypothesize that respondents stated certainty in choice increases with the utility difference between the alternative chosen and the best alternative to that we test this hypothesis using data from two independent choice experiments both focusing on nature values in modelling respondents self reported certainty in choice we find evidence that the stated level of certainty increases significantly as utility difference in choice sets increases in addition stated certainty increases with income furthermore there is some evidence that male respondents are inherently more certain in their choices than females and a learning effect may increase stated certainty we find evidence of this in the first study where the good is described in rather broad and generic terms but not in the second study where a more specific description of the good is used

willingness to pay for curbside recycling with detection and mitigation of hypothetical bias in this article we estimate willingness to pay for curbside recycling using a unique data set we also test for and detect significant hypothetical bias using stated and revealed preference data a short scripted cheap talk statement is used to mitigate the bias and provide more efficient estimates of the welfare impacts of curbside recycling programs copyright 2003 oxford university press

further investigation of voluntary contribution contingent valuation fair share time of contribution and respondent uncertainty in the spirit of randall s resource energy econom 20 197 206 1998 argument for focusing on mapping the performance characteristics of alternative contingent valuation designs and formats the focus of this study is on three tests of the voluntary contribution mechanism we investigate the response effects of three crossed treatments 1 an informational treatment that randomly varies the total cost of providing the good to identify possible fair share effects 2 a split sample informational treatment that makes the time of contribution explicit and 3 elicitation formats that allow respondent uncertainty both as a follow up to a dichotomous choice question and asked directly in a split sample treatment

information and effort in contingent valuation surveys application to global climate change using national internet samples this contingent valuation study investigates the issues of information access and respondent effort and is based on a series of national internet samples the focus is on a split sample treatment basic information bi versus enhanced information ei in the latter significantly expanded information is provided about global climate change and the kyoto protocol using a referendum format we compare the treatment effect bi versus ei on willingness to pay wtp we develop measures of respondent effort in accessing optional information through the technology of web based surveys and jointly model effort and wtp using a simultaneous estimation approach results support the use of the joint modeling approach for objective measures of respondent effort and wtp respondent effort is shown to be positively and significantly related to wtp however use of the optional menu is rather modest counts of pages and time spent and is highly variable both across pages and respondents

discrete choice under preference uncertainty an improved structural model for contingent valuation abstract this paper is concerned with discrete choice contingent value estimation in the presence of response errors we attempt to extend the theoretical frameworks developed by hanemann 1984 amer j agric econom 66 332 341 and cameron 1988 j environ econom management 15 355 379 by introducing preference uncertainty with individual respondents we assume that respondents have incomplete knowledge about their true valuation of a nonmarket resource and thus may give wrong yes no answers on whether or not to pay a given bid amount for the resource a post decisional confidence measure for each observed yes no answer is elicited for characterizing the degree of preference uncertainty with the help of this confidence measure we develop an improved structural model for deriving value estimates data from a forest environment valuation survey are used for the empirical estimations

dubious and dubiouser contingent valuation and the time of day we collect contingent valuation data from 524 student survey respondents over a 3 day 72 hour period data analysis of a hypothetical campus referendum focuses on time of day effects on willingness to pay for a renewable energy project we find that subjects responding to the survey during the night time hours i e between 12 a m and 6 a m do not display the law of demand offering theoretically invalid responses to questions with important policy implications results from this research may have serious implications for the contingent valuation method cvm in short just like your father said nothing good happens after midnight when using the cvm jel q51

efficient estimation methods for closed ended contingent valuation surveys closed ended contingent valuation surveys can be very useful in the evaluation of nonmarket resources respondents merely state whether they would accept or reject a hypothetical threshold amount either as payment for giving up access to the resource or as a fee for its use the authors develop a maximum likelihood procedure which exploits the variation in the threshold values to allow direct and separate point estimates of regression like slope coefficients and error standard deviations without truncation bias their illustration uses data from a survey of recreational fisherman to examine factors which influence individuals willingness to pay copyright 1987 by mit press

two cases for sand in the wheels of international finance the incompatibility of pegged exchange rates international capital mobility and national monetary autonomy is a basic postulate of open economy macroeconomies in the present environment of high capital mobility and political uncertainty even the possibility that governments may utilize their policy autonomy can defeat efforts to peg the exchange rate this leaves two possibilities one is to fix the exchange rate irrevocably through monetary unification the other is to live with floating rates either way a case can be made for throwing sand in the wheels of international finance where monetary unification is not an option this is a may to make distinct national currencies tolerable and international money and capital markets compatible with modest national autonomy in monetary and macroeconomic policy for eu counties striving to create a monetary union it is the only politically and economically feasible way of completing the transition to stage iii of the maastricht process

the effect of common sources of regression error on benefit estimates discussions of the sources of error in recreation demand analysis are common in the existing literature the most traditional line of thought e g gum and martin considers the error component in predicting the individual s recreation behavior to arise from unmeasured socioeconomic factors others e g hanemann attribute at least some of this error to fundamental randomness in human behavior applied statisticians e g hiett and worrall on the other hand suggest that recall of annual number of recreational trips i e the quantity demanded is subject to substantial error still others e g brown et al have argued that recall of explanatory variables such as travel expenses contains error despite the discussion of potential error sources there is no work which relates the sources of error in the demand relationship with benefit measurement 1 of practical importance in recreational demand estimation is whether error assumptions have an influence on welfare measures since it is for public policy decision purposes that recreational demand estimation is usually undertaken will the estimated consumer surplus derived from demand analysis be independent of the assumed source of the error in the regression the purpose of this paper is to explore how the assumptions about sources of error influence estimates of recreation benefits a discussion of the various sources of error in de

speculative trading and oil price dynamic a study of the wti market abstract the aim of this paper is to study the oil price dynamic in west texas intermediate wti market in the us by using statistical and econometric tools we first attempt to identify the long term relationship between wti spot prices and the prices of futures contracts on the new york mercantile exchange nymex subsequently we model the short term dynamic between these two prices and this analysis points up several breaks on this basis a short term markov switching vectorial error correction model ms vecm with two distinct states standard state and crisis state has been estimated finally we introduce the volumes of transactions observed on the nymex for the wti contracts and we estimate the influence of the non commercial players we conclude that the hypothesis of an influence of non commercial players on the probability for being in the crisis state cannot be rejected in addition we show that the rise in liquidity of the first financial contracts as measured by the volume of open interest is a key element to understand the dynamics in market prices

paired comparison estimates of willingness to accept versus contingent valuation estimates of willingness to pay estimating empirical measures of an individual s willingness to accept that are consistent with conventional economic theory has proven difficult the method of paired comparison offers a promising approach to estimate willingness to accept this method involves having individuals make binary choices between receiving a particular good or a sum of money willingness to accept can be inferred from the ranking of dollar amounts and the good of interest using the paired comparison approach mean median willingness to accept for a private good is estimated at 59 52 contingent valuation estimate of willingness to pay for the same good yields a mean median of 28 28 while these estimates are statistically different the ratio of willingness to accept to willingness to pay is less than in most previous studies and closer to ratios found in actual cash experiments

on the matter of parity among financial obligations the lessons of the leasing literature concerning the impact of leases on the debt capacity of a firm are reviewed and summarized to establish an approach to the analysis of the corporate bond refunding decision a general proposition regarding financial obligation parity is established and from that a clear bond refunding decision rule is developed previous debates in the literature about appropriate discount rates and about the appropriate cash flows to be discounted for refunding decisions are clarified the debate in the finance literature during the last decade about the proper approach to the corporate asset leasing decision has given rise to a number of useful insights into issues relating to debt capacity and the valuation of income streams having different risk characteristics indeed the debate turns out to have much in common with the u s space program of the preceding decade in that the technological spin offs resulting from the effort were often as significant as the attainment of the original objective itself our purposes in the present paper are twofold and they are addressed in sequence below first we shall offer what we believe to be some needed additional clarifying observations on the nature of the most recently proposed approaches to the evaluation of lease contracts second we shall extend the lessons derived from the analysis to develop a further important technological spin off the latter has to do with corporate bond refunding decisions in particular the notion of parity among alternative financial obligations which we shall see is central to a proper appraisal of asset leasing arrangements also provides the key to a resolution of the longstanding refunding controversy

valuation and hedging of risky lease payments presented here is a simple formula to value risky corporate lease payments when the amount of debt displaced by a lease depends on the value of the lease the displaced debt tax shields are risky the value of these risky tax shields is less than the value of riskless tax shields the valuation of the lease makes use of a dynamic investment strategy that replicates the lease payments and associated tax shields from displaced debt a useful variation of the valuation formula requires only the contractual cash flows and the yield on lease equivalent debt calculations show that the new formula can produce significantly different lease values from formulas that assume riskless cash flows

contingent valuation theoretical advances and empirical tests since the noaa panel beyond a simple cost effectiveness role and for many policy issues where all the goods or impacts at issue are not readily priced in the market the relevance of economics depends to a large degree on the ability to use contingent valuation cv and other closely related stated preference approaches the government s use of cv as a tool to place a monetary value on damages from the exxon valdez oil spill brought forth strong industry objections to the use of cv in response the national oceanic and atmospheric administration noaa one of the trustee agencies in the exxon valdez case commissioned a blue ribbon panel chaired by kenneth arrow and robert solow to review the use of cv in natural resource damage assessment proceedings the panel s report arrow et al and transmittal letter to the noaa general counsel concluded cv studies can produce estimates reliable enough to be the starting point for a judicial or administrative determination of nat

resource nationalism meets the market political risk and the value of petroleum reserves this paper investigates the effect of resource nationalism on the value of petroleum crude oil and natural gas reserves we develop a framework for treating resource nationalism as political risk and utilize data on reserve transactions from john s herold and political risk ratings from international country risk guide and institutional investor for the period 2000 2006 controlling for other factors that affect reserve value we demonstrate the value destruction of political risk and estimate the political risk discount for 37 countries the paper contributes to both the international business literature and practitioner approaches to political risk analysis in demonstrating use of publicly available market data from real asset transactions to measure the cost of political risk we also show that the discount depends on market conditions the higher expected future petroleum prices are the larger is the discount at any level of political risk this insight adds a new dimension to analysis of political risk which is typically measured and examined without regard to market conditions

an examination of stock market return volatility during overnight and intraday periods 1964 1989 this paper examines the variance of hourly market returns during 1964 89 results indicate that return volatility falls from the opening hour until early afternoon and rises thereafter and is significantly greater for intraday versus overnight periods market variance is also shown to change significantly over time rising after nasdaq began in 1971 rising after trading in stock options began in 1973 falling after fixed commissions were eliminated in 1975 rising after trading in stock index futures was introduced in 1982 and falling after margin requirements for stock index futures became larger in 1988 copyright 1990 by american finance association

operational hedges and the foreign exchange exposure of u s multinational corporations this paper examines the impact of operational hedges of us multinational corporations mncs on their exchange rate exposure the two important contributions of this study are first it documents the importance of operational hedges as significant determinants of exchange rate risk as measured by breadth and depth dimensions of the mnc foreign subsidiary network second this finding remains robust even after examining the impact of operational hedges on exposure separately for negatively and positively exposed mncs

bias in discrete response contingent valuation abstract the empirical literature on discrete response contingent valuation has found that seemingly innocuous changes in the statistical models estimated result in significantly different point estimates of willingness to pay this paper hypothesizes and tests several potential explanations for these results first it investigates and compares the biases inherent in single bounded and double bounded maximum likelihood estimation procedures and examines how they react to various bid designs and sample sizes then it examines the presence and identification of outliers in binary choice data and how these outliers influence estimation finally it presents an alternative approach to addressing the issue of outliers which explicitly acknowledges the possibility of upwardly biased response probabilities

construct validity of dichotomous and polychotomous choice contingent valuation questions in this note we conduct construct validity tests for dichotomous choice dc and polychotomous choice pc contingent valuation questions contrary to previous results we find that dc and pc estimates of willingness to pay are theoretically valid convergent valid and similar in terms of statistical precision similar to previous results pc respondents are less sensitive to information than dc respondents we conclude that dc and pc valuation questions are construct valid for this study sequential pc valuation questions could be used in studies where obtaining information about the certainty or intensity of respondent preferences would be useful

statistical approaches to the fat tail problem for dichotomous choice contingent valuation if a cumulative density function esti mated from dichotomous choice data has an unre alistically fat right hand tail mean willingness to pay wtp will be overestimated truncating the range of integration results in a lower bound esti mate of the true mean wtp a normalization pro cedure proposed by boyle welsh and bishop 1988 unnecessarily depresses the estimate further a new statistical approach is presented that allows a best guess estimate of mean wtp because this estimate involves extrapolation beyond the range of the data it tends to be highly variable jel q21

does realism matter in contingent valuation surveys the importance of stressing the realism or policy relevance of a contingent valuation cv survey is commonly recognized by cv researchers this paper focuses on the relationship between the probability that a subject s response will result in real consequences and the subject s accurate reporting of willingness to pay results from experiments support the argument that efforts to make contingent valuation surveys real are important however our results also suggest that the connection between the survey and the likelihood of a payment must be rather powerful before surveys generate accurate reporting of willingness to pay for a public good

would developing country commitments affect us households support for a modified kyoto protocol abstract would us households be willing to pay more to support a modified kyoto protocol mkp if developing countries had binding future limits on greenhouse gas production we explore this question using data from a unique set of national internet samples and web based surveys using an advisory referendum format the contingent valuation method is applied to estimate annual household willingness to pay wtp for us senate ratification of the kyoto protocol for a split sample treatment the basic kyoto protocol bkp control group versus a mkp that includes limits on future greenhouse gas production for major developing countries treatment group the results indicate that the treatment significantly increases the probability of a yes vote on the advisory referendum econometric modeling results provide evidence that the mkp significantly increases us households median wtp to support the treaty

respondent experience and contingent valuation of environmental goods abstract respondent experience i e a respondent s information set has long been suspected to influence contingent valuation estimates of environmental values we assess the influence of experience by explicitly modeling the relationship between respondent experience and both fitted individual resource values and the conditional variance of these estimated values using three different joint specifications for experience and wtp normal censored normal poisson censored normal and zero inflated poisson censored normal we find discrete jumps in resource values as experience increases from zero and that more experienced respondents have smaller conditional variances simulation of arbitrary levels of experience allows standardization of the amount of information when developing welfare estimates

do foreign owned and u s owned establishments exhibit the same location pattern in u s manufacturing industries there are arguments to support and contradict the proposition that foreign owned and u s owned establishments exhibit similar location patterns within the united states this paper addresses these conflicting views by comparing the location of all manufacturing establishments in the united states held by the u s and by foreign firms the empirical evidence indicates that the location patterns of foreign owned and u s owned establishments differ moreover the most influential factor in explaining the location pattern difference is that foreign owned establishments compared to u s owned establishments favor coastal states i also find evidence to suggest that foreign firms favor states with low unionization rates low wage rates and right to work legislation these results are consistent with arguments that foreign establishments differ from their domestic counterparts and value location attributes differently

do children matter an examination of gender differences in environmental valuation abstract this paper is concerned with the role played by children in a household on choice behaviour related to willingness to pay wtp for environmental goods improvements data from a contingent valuation cvm survey dealing with three environmental improvements are used to examine three hypotheses the first is that after controlling for income individuals with children have higher wtp than childless individuals the second hypothesis is that women with children are willing to pay more for environmental improvements than men with children particularly in the case where there is concern for environmental health risks the third is that childless men and women exhibit significant differences in wtp that arise from greater time constraints faced by women estimated wtp functions are shown to be statistically different for four groups of individuals women with children men with children women without children and men without children parents of either gender are willing to pay more than their childless counterparts valuations of mothers and fathers are statistically different for only one of the three goods being evaluated interestingly it is the fathers mean valuations that are higher this may arise from the fact that these environmental improvements lead to better recreational opportunities and as indicated earlier men are less time constrained further support for this view comes from results that show that valuations of childless men are significantly greater than those for childless women for two goods the paper concludes with some directions for future research in the area

rural amenity values and length of residency new residents of rural communities are often assumed to have preferences for development and conservation that differ from those of longer term residents however the literature offers little to quantify presumed preference heterogeneity this article assesses whether stated preferences differ according to length of residency results are based on a conjoint choice experiment survey of rhode island rural residents heterogeneity according to length of town residency is modeled using dummy variables multiplicative interactions and lagrangian interpolation polynomials results are compared across the three models and identify a range of attributes for which willingness to pay depends on length of residency
