option value empirical evidence from a case study of recreation and water quality a procedure for measuring option value and other preservation values of water quality is developed and applied to a case study area in the south platte river basin colorado benefits from water based recreation activities are the focus of the study the results provide an empirical test and confirmation of weisbrod s proposal that option value and other preservation values represent important social benefits and should be added to the aggregate consumer surplus of recreation activities to determine the total benefit of environmental amenities to society in the absence of such an estimate insufficient resources would be allocated by society to preservation of unique environments such as pristine mountain streams where mineral and energy development may irreversibly degrade water quality

should government fund assisted reproductive techniques a study using willingness to pay during recent years there has been a growth in the use of assisted reproductive techniques arts across europe america and australia this has resulted in debates about whether health insurance should cover this procedure this study used the closed ended ce willingness to pay wtp technique to establish the value the infertile place on in vitro fertilization ivf treatment in scotland the intention is to consider the use of the economic instrument of wtp for informing the debate on the public provision of ivf assuming that the value of the service outweighs the cost public provision should be encouraged the responses suggested that users of the service have a mean wtp of over 5000 for an attempt at ivf this compares with an average government expenditure of 7pound 2700 the internal validity of the ce wtp was also shown with income being positively related to wtp it is concluded that the ce wtp technique is potentially a useful tool for policy makers in considering the public provision of i

elicitation and truncation effects in contingent valuation studies comment abstract this comment reviews some of the findings of bateman et al 1995 which appear to have simplified the choice between alternative benefit measures with dichotomous choice contingent valuation errors in the bateman et al analysis are identified and corrected results are used to review the conclusions

interest on reserves interbank lending and monetary policy abstract a two sector general equilibrium banking model is constructed to study the functioning of a floor system of central bank intervention only retail banks can hold reserves and these banks are subject to a capital requirement creating balance sheet costs of holding reserves an increase in the interest rate on reserves has different qualitative effects from a reduction in the central bank s balance sheet increases in the central bank s balance sheet can have redistributive effects and can reduce welfare a reverse repo facility at the central bank puts a floor under the interbank interest rate and is always welfare improving

valuation of non priced amenities provided by the biological resources within the monteverde cloud forest preserve costa rica abstract to quantify the economic benefits of the monteverde cloud forest preserve and to test the contingent valuation method in a third world setting a contingent valuation survey was designed with five experimental treatments these determined an overall expected value per visitor determined and compared two ways of eliciting value single versus annual lump sum payments and compared average values of costa rican versus non costa rican visitors visitors were willing to pay to prevent the preserve s conversion to agricultural uses monteverde s value as a cloud forest preserve appears much higher than any value it might have in agricultural use despite lower incomes costa rican visitors valued the preserve more highly than non costa rican visitors visitors may have differentiated only weakly between greatly differing bid amounts expected values derived from econometric analysis of the differing experimental treatments suggest that further methodological adaptation of the contingent valuation method may be required 1 when it is applied in third world settings and 2 when precision is critical in estimating wtps

comment on cameron s censored logistic regression model for referendum data abstract t a cameron a new paradigm for valuing non market goods using referendum data maximum likelihood estimation by censored logistic regression j environ econom management 15 355 379 1988 presents what she terms a new paradigm for interpreting referendum data derived from contingent valuation surveys for nonmarket resources we show that since her model is a reparameterization of the usual logistic regression model asymptotic standard errors can be derived for the maximum likelihood estimators of the parameters in either model from the other we also argue that computational convenience in deriving demand relationships or elasticities depends more on the choice of welfare measure than on the choice of a parameterization

a simple general equilibrium model of large excess reserves abstract in a general equilibrium macroeconomic model with a banking system that can hold large excess reserves and is subject to possibly binding capital constraints i study how the quantity of government provided monetary assets is related to the price level in steady state when the central bank does not pay interest on reserves the price level moves one for one with the monetary base if instead the central bank can pay interest on reserves at market rates the price level can decouple from the quantity of monetary assets in the economy a larger monetary base need not imply a higher price level however for large enough levels of reserves the capital constraint binds and the tight link between money and prices reemerges

estimating willingness to pay for renewable energy in south korea using the contingent valuation method the importance of renewable energy as a response to climate change is universally acknowledged however its successful implementation requires public approval and cooperation this study aims to identify the level of renewable energy acceptance in korea by estimating korean consumers additional willingness to pay wtp using the contingent valuation cv method which is the most widely used to analyze consumer preferences the estimation results indicate that korean consumers are willing to pay an additional usd 3 21 per month for electricity generated with renewable energy however wtp in korea is low relative to other advanced nations indicating that these values could be influenced through policies aimed at improving knowledge and acceptance of renewable energy sources among korean consumers

money credit and banking in monetary models where agents are subject to trading shocks there is typically an ex post inefficiency since some agents are holding idle balances while others are cash constrained this problem creates a role for financial intermediaries such as banks who accept nominal deposits and make nominal loans in general financial intermediation improves the allocation the gains in welfare come from the payment of interest on deposits and not from relaxing borrowers liquidity constraints we also demonstrate that when credit rationing occurs increasing the rate of inflation can be welfare improving

a test of the equality of closed ended and open ended contingent valuations a test is developed to find whether open ended and closed ended contingent valuation mechanisms lead to significantly different results the test is based on joint estimation of willingness to pay responses to open and closed ended questions asked of the same sample of individuals in a public good example individuals do respond differently depending on question format possible explanations include different incentives for strategic behavior and respondents lack of familiarity with the open ended question type no differences in willingness to pay were found in a private good example

understanding economic inequality through the lens of caste research on economic inequality has largely focused on understanding the relationship between organizations and inequality but has paid limited attention to the role of institutions in the creation and maintenance of inequality in this article we use insights from the caste system an institution that perpetuates socio economic inequalities and limits human functions to elaborate on three elements of economic inequality uneven dispersions in resource endowments uneven access to productive resources and opportunities and uneven rewards to resource contributions we argue that economic inequalities persist because these three different elements of inequality feed from and reinforce each other our study underscores the potential of the caste lens to inform research on economic inequality as well as organizational theory and practice

when does a central bank s balance sheet require fiscal support abstract using a simple general equilibrium model we argue that it would be appropriate for a central bank with a large balance sheet composed of long duration nominal assets to have access to and be willing to ask for support for its balance sheet by the fiscal authority otherwise its ability to control inflation may be at risk this need for balance sheet support a within government transaction is distinct from the need for fiscal backing of inflation policy that arises even in models where the central bank s balance sheet is merged with that of the rest of the government

the worth of a possum valuing species with the contingent valuation method the focus of this paper is on methods of assessing the value peopleplace on the conservation of species for use in policy making of principalinterest is the relatively new methodology of contingent valuation whichis a method for asking people directly about their preferences the paperpresents an application of the contingent valuation method to theconservation of an endangered species in the state of victoria australia the results emphasise the importance of careful survey design implementation and analysis as well as the precise definition of theenvironmental good being valued consequently the contingent valuationmethod does provide information relevant to decision making processesbased on monetary economic considerations thus in orthodox economicterms it makes sense to conserve species but there are other moral andethical grounds for conserving species as well

a search based model of the interbank money market and monetary policy implementation we present a search based model of the interbank money market and monetary policy implementation banks are subject to reserve requirements and the central bank tenders reserves interbank payments redistribute holdings and banks trade with each other in a decentralized over the counter market the central bank provides standing facilities where banks can either deposit surpluses or borrow to cover shortfalls of reserves overnight the model provides insights on liquidity trading volume and rate dispersion in the interbank market features largely absent from the canonical models in the tradition of poole 1968 and fits a number of stylized facts for the eurosystem observed during the recent period of unconventional monetary policies moreover it provides insights on the implications of different market structures

application of stochastic choice modeling to policy analysis of public goods a case study of air quality improvements this paper demonstrates the applicability of the stochastic choice method in performing policy analysis of changes in public goods using survey data the air quality problem studied involves air pollution control for the tampa bay area of florida and relatively simple choices between changes in a public good and disposable income it illustrates the use of surveys as a public forum in which preferences are revealed 26 references 2 tables

valuation of ecotourism resources using a contingent valuation method the case of the korean dmz abstract the korean demilitarized zone dmz which has been untouched by human interference for the last half century has become a sanctuary for rare species of animals and plants conflicts concerning development between communities and environmentalists are arising estimates of the preservation value of the dmz are necessary for society to properly address these issues such estimates will help policy makers address issues of conservation management sustainable development and public financial support given this situation the objectives are two fold the primary objective of this study is to obtain estimates of the preservation value of the korean dmz and civilian control zone ccz a secondary objective is to examine the potential for hypothetic bias in respondents answers in a contingent valuation method framework findings suggest hypothetical bias is present in the survey including a real payment vehicle may reduce hypothetical bias in eliciting willingness to pay wtp best estimates are the mean wtp is us 16 74 per capita aggregate preservation value lies between us 264 and 602 million these findings indicate that conservation of the dmz and ccz is not only important for moral and ecological reasons but the dmz and ccz are of considerable economic value to south koreans any development unfriendly to the environment will degrade the quality of the ecosystem of the dmz as well as decrease its economic value

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

economic valuation of biodiversity sense or nonsense this paper critically evaluates the notion and application of economic monetary valuation of biological diversity or biodiversity for this purpose four levels of diversity are considered genes species ecosystems and functions different perspectives on biodiversity value can be characterized through a number of factors instrumental vs intrinsic values local vs global diversity life diversity vs biological resources etc a classification of biodiversity values is offered based on a system of logical relationships among biodiversity ecosystems species and human welfare suggestions are made about which economic valuation methods can address which type of biodiversity value the resulting framework is the starting point for a survey and evaluation of empirical studies at each of the four levels of diversity the contingent valuation method is by far the most used method an important reason is that the other valuation methods are unable to identify and measure passive or nonuse values of biodiversity at first sight the resulting monetary value estimates seem to give unequivocal support to the belief that biodiversity has a significant positive social value nevertheless most studies lack a uniform clear perspective on biodiversity as a distinct concept from biological resources in fact the empirical literature fails to apply economic valuation to the entire range of biodiversity benefits therefore available economic valuation estimates should generally be regarded as providing a very incomplete perspective on and at best lower bounds to the unknown value of biodiversity changes 2001 elsevier science b v all rights reserved

ex ante willingness to pay with supply and demand uncertainty implications for valuing a sea turtle protection programme it is argued that ex antewillingness to pay is appropriately measured as a function of subjective supply and demand probabilities an exploratory case study of a loggerhead sea turtle protection programme is used to show how estimates of these probabilities can be obtained from a sample survey and how a change in probabilities determines contingent choice empirical results confirm that subjective probabilities are important when explaining ex antewillingness to pay attempts to estimate the determinants of ex antewillingness to pay without controlling for subjective probabilities will result in specification bias it is important that subjective probability information is gleaned from contingent valuation survey respondents and included in empirical models of contingent choice

does question format matter valuing an endangered species a three way treatment design is used to compare contingent valuation response formats respondents are asked to value an endangered species the red cockaded woodpecker and the restor ation of its habitat following a natural disaster for three question formats open ended payment card and double bounded dichotomous choice differences in survey response rates item non response rates and protest bids are examined bootstrap techniques are used to compare means across formats and to explore differences in willingness to pay wtp distribution functions convergent validity is found in a comparison of mean wtp values although some differences are apparent in the cumulat ive distribution functions differences across formats are also identified in item non response rates and proportion of protest bids overall the payment card format exhibits desirable properties relative to the other two formats

degreasing the wheels of finance can there be too much trading in financial markets we construct a dynamic general equilibrium model where agents face idiosyncratic liquidity shocks a financial market allows agents to adjust their portfolio of liquid and illiquid assets in response to these shocks the optimal policy is to restrict access to this market because portfolio choices exhibit a pecuniary externality agents do not take into account that by holding more of the liquid asset they not only acquire additional insurance against these liquidity shocks but also marginally increase the value of the liquid asset which improves insurance for other market participants

valuing health care using willingness to pay a comparison of the payment card and dichotomous choice methods this paper compares willingness to pay wtp estimates generated from the dichotomous choice dc and payment card pc approaches in a split sample wtp experiment concerned with allocating scarce health care resources across three health care interventions the dc approach is shown consistently to generate larger welfare estimates than the pc observed difference between pc and dc experiments cannot be explained by the inclusion of non demanders or methods of statistical analysis but may be partly explained by yea saying no evidence of range bias or mid point bias was found with pc responses data were also collected on respondents ordinal rankings of the three interventions and person trade offs ptos neither of these approaches converged with wtp future work must address the decision heuristics individuals employ when responding to valuation experiments

modernizing without westernizing social structure and economic action in the indian financial sector to better understand whether the transition by asian countries toward market economies mirrors the path taken in the west we ask how embedded network ties between equity analysts and the chief executive officers ceos of the firms that they follow in india influence the accuracy of analysts earnings forecasts we contrast traditional institutions of caste and regional language with contemporary institutions such as universities as the locus of such ties we posit that ceos from the postreform generation are more likely to transfer material private information via their school ties while prereform generation ceos favor caste or language ties contrasting domestic business groups bgs with western multinational corporations mncs as organizational contexts we argue that bgs legitimate the transfer of private information along particularistic ties whereas mncs mitigate such transfers our conceptual framework is supported by analyses that draw on a sample of 1 552 earnings forecasts issued between 2001 and 2010 by 296 equity analysts our findings suggest that the embeddedness perspective should be broadened to incorporate the influence of the larger historical social structures within which economic action is embedded and to view bgs as carriers and repositories that blend modern management practices with particularistic behavioral patterns among top executives

exit strategies for monetary policy abstract in response to the financial crisis of 2007 08 all major central banks decreased interest rates to historically low levels and created large excess reserves central bankers and academics currently discuss how to implement monetary policy going forward we find that paying interest on reserves ior is optimal if the central bank has full fiscal support if the central bank has no fiscal support reducing reserves is optimal this can be achieved by reserve absorbing operations which hold the size of the balance sheet constant or by selling assets which reduces the size of the balance sheet

on the gap between payment card and closed ended cvm answers the paper presents contingent valuation cv estimates of benefits provided by a proposed kalkalpen national park in austria although descriptive results of welfare measures are presented the focus of the paper is on methodological questions concerning the analysis of cv answers evidence is given regarding the difference between payment card pc answers and closed ended question formats based on different estimation models for cv questions substantial differences are found between closed ended and payment card welfare measures on average pc willingness to pay wtp measures are below the closed ended figures since the evaluation models are based on different premises in the calculation of wtp figures a more precise disclosure of the underlying evaluation methods is required if different question formats are compared to one another identical assumptions on the probability distributions have to be assumed whenever open and closed ended cv welfare measures are compared taking theoretical argument

the over the counter theory of the fed funds market a primer we present a dynamic over the counter model of the fed funds market and use it to study the determination of the fed funds rate the volume of loans traded and the intraday evolution of the distribution of reserve balances across banks we also investigate the implications of changes in the market structure as well as the effects of central bank policy instruments such as open market operations the discount window lending rate and the interest rate on bank reserves

monetary policy in a channel system abstract channel systems for conducting monetary policy are becoming increasingly popular despite its popularity the consequences of implementing policy with a channel system are not well understood we develop a general equilibrium framework of a channel system and study the optimal policy a novel aspect of the channel system is that a central bank can tighten or loosen its policy without changing its policy rate this policy instrument has so far been overlooked by a large body of the literature on the optimal design of interest rate rules

access policy and money market segmentation abstract deviations between interest rates paid in the swiss franc unsecured money market and the respective libor rate are analysed for a period spanning the financial crisis first banks that have access to sources of secured central bank and interbank funding pay less than other banks second foreign banks not chartered in switzerland pay more than domestic banks third both lines of segmentation are economically relevant but limited due to open access to sources of secured funding thus access policy matters for monetary policy implementation and financial stability

trade dynamics in the market for federal funds we develop a model of the market for federal funds that explicitly accounts for its two distinctive features banks have to search for a suitable counterparty and once they have met both parties negotiate the size of the loan and the repayment the theory is used to answer a number of positive and normative questions what are the determinants of the fed funds rate how does the market reallocate funds is the market able to achieve an efficient reallocation of funds we also use the model for theoretical and quantitative analyses of policy issues facing modern central banks

when did the fomc begin targeting the federal funds rate what the verbatim transcripts tell us in october 1982 the fomc deemphasized m1 and moved to what is commonly referred to as a borrowed reserves operating procedure sometime thereafter the fomc switched to a funds rate targeting procedure but never formally announced the change given the close correspondence between a borrowed reserves operating procedure and a funds rate targeting procedure thornton 1988 suggested that the fomc went immediately to a funds rate targeting procedure others date the switch to the funds rate procedure later meulendyke 1998 suggests the switch came in late 1987 while others suggest the change occurred later this paper reviews the verbatim transcripts of the fomc meetings to establish the timing of the switch the verbatim transcripts suggest that the fomc effectively switched to a funds rate targeting procedure in 1982 the documentary evidence is supported by an analysis of the spread between the funds rate and the funds rate target which suggests that the differences in the behavior of the spread before october 1979 and after october 1982 are relatively small and economically unimportant

a unified framework for monetary theory and policy analysis search theoretic models of monetary exchange are based on explicit descriptions of the frictions that make money essential however tractable versions of these models typically make strong assumptions that render them ill suited for monetary policy analysis we propose a new framework based on explicit micro foundations within which macro policy can be studied the framework is analytically tractable and easily quantifiable we calibrate the model to standard observations and use it to measure the cost of inflation we find that going from 10 percent to 0 percent inflation is worth between 3 and 5 percent of consumption much higher than previous estimates

willingness to pay for antihypertensive therapy further results a measurement experiment regarding willingness to pay for antihypertensive therapy is reported a new type of binary willingness to pay question is used that allows for different degrees of certainty with respect to the responses mean willingness to pay is derived from a simple expected utility model and estimated using maximum likelihood methods the estimated parameters are highly significant with predicted signs and imply a mean willingness to pay of about sek 800 130 per month the explanatory power of the equation that only includes certain yes no responses is as expected much higher than that of the equation where only uncertain responses are included

contingent valuation and social choice the contingent valuation method for estimating the existence value of natural resources is examined for psychophysical robustness statistical reliability and economic sensibility extensions of standard models for willingness to pay and suitable econometric techniques for analyzing these models are developed the analysis is applied to a series of experiments on the value of preserving wilderness areas in the western united states the results call into question the reliability of the cv method for estimating existence values

nonparticipation or misspecification the impacts of nonparticipation on dichotomous choice contingent valuation dichotomous choice or referendum contingent valuation surveys have become the predominate choice for valuing goods and services otherwise not valued in a standard market nonmarket goods and services a number of researchers have recently recommended that dichotomous choice contingent valuation studies include a follow up question to all no responses to determine whether the no response is a result of unwillingness to pay or nonparticipation if the goal of the study is to investigate the impact of covariates on either mean willingness to pay or the probability of nonparticipation simple identification of indifferent individuals will not suffice a simulation study shows that existing econometric models designed to account for nonparticipation are extremely sensitive to misspecification bias accurate identification of the probability of nonparticipation is hampered by potential misspecification of the distribution of willingness to pay

testing for misspecification in the referendum contingent valuation approach binary choice models are frequently used in the analysis of referendum contingent valuation data because omitted regressors heteroskedasticity and distribution asymmetry in these models result in inconsistent parameter estimates it is important that misspecification tests be undertaken in this article conditional moment tests for these problems are presented and applied to data from two referendum contingent valuation studies results show that some models have misspecification problems and that these problems affect the estimation of welfare measures

re use of collateral in the repo market this paper introduces a methodology to estimate the re use of collateral based on actual transaction data with a comprehensive data set from the swiss franc repo market we are able to provide the first systematic study on the re use of collateral we find that re using collateral was most popular prior to the financial crisis when roughly 10 of the outstanding interbank volume was secured with re used collateral furthermore we show that the re use of collateral increases with the scarcity of collateral by giving an estimate of the collateral re use and explaining its drivers the paper contributes to the on going debate on collateral availability

comparison of contingent valuation and conjoint analysis in ecosystem management abstract contingent valuation cv and conjoint analysis were used to estimate landowner s willingness to pay wtp for ecosystem management on non industrial private forest land the results suggest that even when conjoint and cv questions are the same except for rating and pricing format respectively wtp estimates are quite different since most conjoint models essentially count maybe responses to valuation questions as yes responses we conclude that conjoint model results often produce wtp estimates that are biased upwards

inference and optimal design for a welfare measure in dichotomous choice contingent valuation this paper considers the use of contingent valuation to estimate non market benefits from separately valued nested goods survey respondents were asked referendum wtp questions regarding either a scheme to protect the whole area of a wetland or a

valuing public goods discrete versus continuous contingent valuation responses independent applications of open ended and dichotomous choice formats are compared using tests of means estimating joint likelihood functions and nonparametric tests of distributions the null hypothesis of no difference in the open ended and dichotomous choice estimates of central tendency cannot be rejected for two out of three data sets while estimated standard deviations are significantly different for all three data sets in addition actual dichotomous choice means and standard deviations exceed those from comparable synthetic dichotomous choice data sets suggesting either open ended questions underestimate values or dichotomous choice bid structures may lead to systematic overestimates

the endangered species act and economic values a comparison of fines and contingent valuation studies abstract economic theory holds that the level of punishment set for a violation of a law reflects or should reflect the marginal social damage of the violation this paper considers the implications of this theory with respect to the endangered species act of 1973 esa in particular we examine the punishment set forth in the esa as an indicator of marginal social damage we compare the level of punishment or fines in the esa to other attempts at measuring the marginal social value of threatened and endangered species namely contingent valuation method studies the comparison indicates that fines in the esa do not depict the marginal social damage incurred with each taking of a threatened or endangered species further the comparison shows that the fines are if anything too low possible modifications to the esa should consider a fine structure that reflects the degree or level of species endangerment proposed or existing endangered species legislation in other nations should perhaps also incorporate such a structure

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

comparing benefit estimates from travel cost and contingent valuation using confidence intervals for hicksian welfare measures an approach to determining whether benefit estimates derived from the travel cost method and contingent valuation method are statistically different is presented unlike past comparisons compensating variation is estimated for both methods benefit comparisons are made more rigorous by use of confidence intervals which are developed using the same krinsky and robb simulation technique for both valution mothods the techniques are applied to deer hunting in california while point estimates of benefits from both truncated and untruncated adjusted travel cost methods are lower than the contingent valuation method the confidence intervals on the untruncated travel cost method do overlap the contingent valution method benefit estimates

open market operations abstract in an open market operation the central bank swaps currency for bonds we show how injecting money in this way is different from transfers the way policy is usually formulated the model captures liquidity explicitly by modeling the roles of assets in frictional exchange under various specifications for market structure and the acceptability or pledgeability of assets we discuss implications for the fisher and quantity equations the possibility of negative nominal yields liquidity traps and market segmentation when liquidity is endogenized using information theory multiple equilibria emerge with different policy predictions interest on reserves and quantitative easing are discussed
