factors influencing differences between survey and market based environmental value measures a unique us database combining survey and housing data is used to obtain household level stated and market based willingness to pay wtp measures to avoid living near landfills systematic differe

monte carlo benchmarks for discrete response valuation methods this paper argues that the belief that discrete contingent valuation cv questions yield substantially larger estimates of the mean and the median willingness to pay wtp for nonmarket resources in comparison to open ended cv questions is unfounded monte carlo experiments estimate the factors influencing the performance of wtp estimates based on discrete response models most of the error arises from the specification errors common to the empirical models in the literature these experiments suggest models where wtp is dominated by nonuse or passive use values are likely to have smaller errors than where large use values influence these decisions

estimating willingness to pay for a cycling event using a willingness to travel approach abstract this study examines the monetary value of nonmarket benefits to participants of an active sport tourism event such as happiness and pride from participating in an event willingness to travel wtt greater distances for future events is assessed and converted into willingness to pay wtp estimates using travel costs using survey data from the 2014 and 2015 blood sweat gears bike ride the intended visitation models show that changes in travel cost have a significant negative effect wtp to revisit the event was between 41 and 57 the likelihood of return visit decreases as travel costs increase indicating that wtp estimates are internally valid wtp estimates stemming from two years of data collection are stable suggesting that they are also temporally reliable this study demonstrated the feasibility of using stated preference wtt questions to assign a monetary value to nonmarket benefits of active sport tourists

giving stated preference respondents time to think results from four countries previous studies have found that contingent valuation cv respondents who are given overnight to reflect on a cv scenario have 30 40 lower average willingness to pay wtp than respondents who are interviewed in a single session this time to think ttt effect could explain much of the gap between real and hypothetical wtp observed in experimental studies yet giving time to think is still rare in binary or multinomial discrete choice studies we review the literature on increasing survey respondents opportunities to reflect on their answers and synthesize results from parallel ttt studies on private vaccine demand in four countries across all four countries we find robust and consistent evidence from both raw data and multivariate models for a ttt effect giving respondents overnight to think reduced the probability that a respondent said he or she would buy the hypothetical vaccines average wtp fell approximately 40 respondents with time to think were also more certain of their answers and a majority said they used the opportunity to consult with their spouse or family we conclude with a discussion of why researchers might be hesitant to adopt the ttt methodology

the individual travel cost method with consumer specific values of travel time savings the treatment of the opportunity cost of travel time in travel cost models has been an area of research interest for many decades our analysis develops a methodology to combine the travel distance and travel time data with respondent specific estimates of the value of travel time savings vtts the individual vtts are elicited with the use of discrete choice stated preference methods the travel time valuation procedure is integrated into the travel cost valuation exercise to create a two equation structural model of site valuation since the travel time equation of the structural model incorporates individual preference heterogeneity the full structure model provides a travel cost site demand model based upon individualized values of time the methodology is illustrated in a study of recreational birdwatching more specifically visits to a stork village in poland we show that the usual practice of basing respondents vtts on 1 3 of their wage rate is largely unfounded and propose alternatives including a separate component of the travel cost survey aimed at valuation of respondents vtts or as a second best asking if they wish if their journey was shorter and for those who do use full hourly wage as an indicator of their vtts

utility consistent discrete continuous choices in soil conservation a utility consistent model of participation and participation intensity choices for a voluntary soil conservation program is developed a modified form of roy s identity is used to derive a two equation system that links the discrete dichotomous choice participation and the continuous choice intensity to the same utility function the model corrects for selectivity bias that arises in single equation approaches an application to a filter strip program in two counties in illinois and michigan demonstrates that different factors affect responses to the program across the sample regions estimated willingness to accept payments for participation in the program suggest policy impacts are not uniform across locations

macroeconomic effects of active labour market programmes in a union wage setting model the recent western european policy debate on unemployment has emphasized the benefits of active labor market programs the authors analyze the effects on wage pressure and equilibrium employment in a union wage setting framework programs are wage reducing to the extent that they help maintain effective labor force participation but they may also weaken insider incentives for wage restraint as the disutility of layoffs becomes smaller targeting the long term unemployed is crucial for the success of active labor market policy since the welfare effects on the laid off then are more heavily discounted and employment opportunities are redistributed from insiders to outsiders copyright 1995 by royal economic society

valuing environmental resources through demand for related commodities we examine the revealed preference theory underlying the welfare analysis of public goods e g environmental quality by observing the consumption of related commodities inspired by larson 1991 and ebert 1998 and extended from eom and larson 2006 an empirical strategy is formulated consistent with the theory of uniquely deriving use and nonuse values for a change in the public good we show that the weak complementarity assumption and the willig condition the common preference assumptions used to support the revealed preference methods for non market valuation may be tested as parameter restrictions a study of water quality valuation is presented to illustrate the proposed empirical strategy results show that the weak complementarity assumption and the willig condition generally do not hold in the case study and the consumer surplus derived from the indirect valuation method deviates largely from the exact welfare measures

determinants of participation in accelerated vehicle retirement programs one potential way to reduce hydrocarbon emission is through accelerated vehicle retirement programs however it is difficult to forecast participation rates in these programs because the number and characteristics of participants are likely to vary with the price offered to attract old cars this paper presents a theoretical model of the owner s car tenure and scrappage decision an econometric model of participation is then developed and estimated using data from a recent old vehicle scrap program in delaware participation rates at different possible offer prices are then predicted

unsecured debt with public insurance from bad to worse abstract in u s data income interruptions the receipt of public insurance and the incidence of personal bankruptcy are all closely related the central contribution of this paper is to evaluate bankruptcy protection and public insurance in a unified setting where each program alters incentives in the other our analysis delivers two striking conclusions first we find that u s personal bankruptcy law is an important barrier that prevents the public insurance system from improving welfare second contrary to popular belief we find that increases in the generosity of public insurance will lead to more not less bankruptcy

sparkling wine choice from supermarket shelves the impact of certification of origin and production practices we report the results of a study based on revealed and stated preference data on choice of prosecco wines in retail stores close to the origin of production in northern italy emphasis is placed on ability to reconcile the utility structure of stated preference data with that underlying revealed preference data we extend the analysis to cover nonattendance of key attributes such as price and certification of origin while controlling for the large range of brand effects

perceptions versus objective measures of environmental quality in combined revealed and stated preference models of environmental valuation abstract this study examines perceptions and objective attribute measures in discrete choice models of recreation site choice behavior these forms of attribute measurement are examined in individual and combined revealed preference stated preference models our results suggest that the model based on perceptions slightly outperforms the models based on objective attribute measures however issues such as the definition of the choice set and the measurement of welfare present significant challenges when using perceptions data

combining revealed and stated preference data to estimate the nonmarket value of ecological services an assessment of the state of the science this paper reviews the marketing transportation and environmental economics literature on the joint estimation of revealed preference rp and stated preference sp data the rp and sp approaches are first described with a focus on the strengths and weaknesses of each recognizing these strengths and weaknesses the potential gains from combining data are described a classification system for combined data that emphasizes the type of data combination and the econometric models used is proposed a methodological review of the literature is pursued based on this classification system examples from the environmental economics literature are highlighted a discussion of the advantages and disadvantages of each type of jointly estimated model is then presented suggestions for future research in particular opportunities for application of these models to environmental quality valuation are presented

what happens when information leaves a market evidence from postbankruptcy consumers federal law mandates the removal of personal bankruptcies from credit reports after 10 years the removal s effect is market efficiency in reverse the short term effect is a spurious boost in apparent creditworthiness especially for the more creditworthy bankrupts delivering a substantial increase in both credit scores and the number and aggregate limit of bank cards the longer term effect is lower scores and higher delinquency than initial full information scores predict these findings relate to both the debate over the bankruptcy code and the wisdom of influencing market clearing by removing information

consumer bankruptcy and financial health this paper estimates the effect of chapter 13 bankruptcy protection on financial health using a new data set linking bankruptcy filings to credit bureau records our empirical strategy uses the leniency of randomly assigned judges as an instrument for chapter 13 protection we find that chapter 13 protection decreases an index measuring adverse financial events such as civil judgments and repossessions by 0 323 standard deviations and increases the probability of being a homeowner by 13 2 percentage points chapter 13 protection has little impact on open unsecured debt but decreases the amount of debt in collections by 1 333

estimating the benefit incidence of an antipoverty program by propensity score matching this brief summarizes the results of a gender impact evaluation study entitled estimating the benefit incidence of an antipoverty program by propensity score matching conducted between 1997 and 1998 in argentina the study observed that the average direct gain to the participant is found to be about half the gross wage over half of the beneficiaries are in the poorest decile nationally and 80 percent are in the poorest quintile the propensity score matching psm estimator is reasonably robust to a number of changes in methodology participants are more likely to be poor than non participants participants are less well educated live in poorer neighborhoods and are more likely to be members of neighborhood associations and political parties average gains are similar between men and women but are higher for younger workers funding for the study derives from the world bank research committee

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

rethinking cholera and typhoid vaccination policies for the poor private demand in kolkata india summary the old familiar diseases of cholera and typhoid remain a serious health threat in many developing countries health policy analysts often argue that vaccination against cholera and typhoid should be provided free because poor people cannot afford to pay for such vaccines and because vaccination confers positive economic externalities on unvaccinated individuals in 2004 we conducted a contingent valuation cv survey of 835 randomly selected adults from two neighborhoods in kolkata india to provide information on private demand for cholera and typhoid vaccines for themselves and for household members to support more nuanced financial and economics analyses of such vaccination programs the median private economic benefits of providing a typhoid vaccine to a household with five members is about us 23 in a middle income neighborhood us 27 for a cholera vaccine and us 14 in a low income slum us 15 for a cholera vaccine our research raises an intriguing possibility if user charges were set at a level to recover the costs of a vaccination program there could be sufficient demand for the vaccine so that coverage of the vaccinated population might ensure that all the remaining unvaccinated individuals would be protected as well through indirect herd protection

will they buy it the potential for marketing organic vegetables in the food vending sector to strengthen vegetable safety a choice experiment study in three west african cities abstract considering the hazardous use of synthetic pesticides in vegetable production in urban west africa this research investigated the marketing potential of organic vegetables in the food vending sector of cotonou benin accra ghana and ouagadougou burkina faso certified organic production and marketing was examined as a potential strategy to improve chemical food safety a stratified random sampling strategy was applied to study the preferences of food vendors n 180 and consumers n 360 vegetable use risk perception choice preferences and willingness to pay wtp for organic certification were specifically analyzed the results showed that awareness of chemical contamination risks was generally low appearance of a product was central to vendor choice consumers attributed similar utility to taste and organic certification consumer wtp was calculated to be a premium of 1 04 usd per plate if the food served contained only certified organic vegetables in restaurants this would mean an average premium of 19 for a meal if certified organic vegetable production is to make a positive impact on food safety in urban west africa we suggest concentrating marketing efforts on the educated elite who frequent restaurants however considering that restaurant owners exhibited a lower preference for organic certification than lower class food vendors the marketing situation is difficult we therefore conclude that demand from the food vending sector alone will not institutionalize domestic certification mechanisms this underlines the need for public commitment to facilitating such change

willingness to pay for quality improvements comparative statics and interpretation of contingent valuation results this paper extends variation function theory by examining the effects of changes in prices quality and income on willingness to pay for quality change comparative static effects are found for both on site users and nonusers of the resource these results are used to interpret contingent valuation empirical models for example the substitution and complementary relationships between trips to natural resource sites can be identified this paper also suggests tests for comparison of contingent valuation with recreation demand models and other tests of validity

precision of dichotomous choice contingent valuation welfare measures some simulation results the purpose of this research is to examine the roles of individuals heterogeneous economic factors and model misspecification in dichotomous choice contingent valuation welfare measurement willingness to pay for an improvement of environmental quality is studied simulation results indicate that the precision of welfare estimates increases with individuals income levels and decreases with the price of the quality related good the dependence of the consumption of the quality related good on the environmental quality also affects the reliability of welfare estimates

estimating the demand for a new technology bt cotton and insecticide policies this article examines the potential demand for bt cotton in the southeast from information gathered in the first year of commercialization we combine revealed preference rp data on adoption of bt cotton varieties with stated preference sp data on willingness to adopt to estimate demand using a double bounded maximum likelihood procedure using estimated demand equations we simulate the costs of reducing conventional insecticide applications through subsidization of bt cotton results indicate that reducing cotton insecticide applications by 40 in the southeast would require a 21 acre subsidy with total annual program costs between 53 million and 60 million

policy evaluation with combined actual and contingent response data the city of marietta georgia experimentally switched from flat fee financing to volume based pricing for its trash services in january 1994 both before and during the experiment detailed data on individuals observed responses to the actual introduction and contingent behavioral responses to a hypothetical introduction of volume based pricing were collected this study applies these data and investigates the methodology of collecting contingent behavior data and their use in policy analysis in particular this study empirically evaluates the effect of experience with the policy on responses to contingent behavior questions and tests for potential bias in the contingent behavior data

combining revealed and stated preference methods to value environmental amenities at residential locations this paper combines an established revealed preference method discrete choice he donic analysis and a relatively new stated refer ence method choice based conjoint analysis in order to estimate more accurately the aesthetic benefits generated by the presence and quality of environmental amenities associated with residen tial locations it applies the combined approach to the housing market of fairfield connecticut which contains several environmental amenities and is experiencing an improvement in the quality of its coastal wetlands due to active restoration efforts jel q26

debt relief and debtor outcomes measuring the effects of consumer bankruptcy protection consumer bankruptcy is one of the largest social insurance programs in the united states but little is known about its impact on debtors we use 500 000 bankruptcy filings matched to administrative tax and foreclosure data to estimate the impact of chapter 13 bankruptcy protection on subsequent outcomes exploiting the random assignment of bankruptcy filings to judges we find that chapter 13 protection increases annual earnings by 5 562 decreases five year mortality by 1 2 percentage points and decreases five year foreclosure rates by 19 1 percentage points these results come primarily from the deterioration of outcomes among dismissed filers not gains by granted filers jel d14 i12 j22 j31 k35

is meta analysis a noah s ark for non market valuation this paper describes meta analytical methods as they have been applied to non market valuation research these studies have been used to review and synthesize literature and more recently in benefit transfer this second use imposes a higher standard on the consistency in economic concepts being summarized and in the resources included in a meta analysis to meet this need the paper proposes and illustrates a structural framework using a generalized method of moments estimator to estimate the parameters of a preference function with the benefits estimates usually encountered in meta analytic summaries

a semi parametric estimator for revealed and stated preference data an application to recreational beach visitation abstract we present a semi parametric approach for jointly estimating revealed and stated preference recreation demand models the discrete factor method dfm allows for correlation across demand equations and incorporates unobserved heterogeneity our model is a generalized negative binomial with random effects the random effect is composed of a discrete representation of unobserved heterogeneity and a factor loading that translates the heterogeneity measure into a demand effect our empirical application is to beach recreation demand in north carolina statistical evidence supports our dfm specification which imposes less restriction on model dispersion and incorporates unobserved heterogeneity in a flexible manner elasticity estimates are smaller than those derived from models with parametric specifications for unobserved heterogeneity and welfare estimates are slightly larger and less precise while parametric models clearly dominate if the specification of unobserved heterogeneity is correct the semi parametric dfm provides a flexible alternative in cases where mis specification is a potential problem

convergent validity and the time consistency of preferences evidence from the iowa lakes recreation demand project we examine the consistency of preferences over time and as implied by revealed versus stated preference contingent behavior data studies in this area are typically based upon a single site and focus on consumer response to changes in travel cost or site access we use data from the iowa lakes project which provides information on usage patterns over several years and for 132 lakes along with detailed water quality data this allows us to test for convergence in how individuals respond to changing site characteristics as well as the consistency of preferences over time and between actual versus contingent trips

evaluation of nonmarket goods recovering unconditional preferences a new approach is proposed for the evaluation of nonmarket goods starting from a complete or incomplete conditional demand system for market goods which is observable and depends on nonmarket goods this information is not sufficient to recover the underlying preference ordering of the representative consumer the central idea is to employ additional marginal willingness to pay functions for the nonmarket goods since they can be estimated either together with the demand system or in a separate step they are less arbitrary than the assumptions or hypotheses usually made if the entire system is weakly integrable the underlying ordering and appropriate welfare measures can be derived in this article i investigate the relationship between conditional and unconditional demand systems present sufficient conditions for weak integrability and demonstrate the practicability of the procedure proposed by means of three examples

improving environmental valuation estimates through consistent use of revealed and stated preference information abstract environmental valuation data from stated and revealed preference methods are integrated into a unified model of preferences for environmental quality improvement that identifies the use and nonuse components of the total value estimate this articulates clearly what parts of the total value estimate come from each type of data and permits tests of whether estimated preferences satisfy weak complementarity between the environmental good of interest and related private goods the statistical advantages of using more information for the valuation problem are exploited while retaining flexibility to identify value estimates from any individual method of analysis

combining revealed preference data with stated preference data a latent class approach a substantial literature exists combining data from revealed preference rp and stated preference sp sources aimed either at testing for the convergent validity of the two approaches used in nonmarket valuation or as a means of drawing on their relative strengths to improve the ultimate estimates of value in doing so it is assumed that convergence of the two elicitation approaches is an all or nothing proposition i e the rp and sp data are either consistent with each other or they are not the purpose of this paper is to propose an alternative framework that allows for possible divergence among individuals in terms the consistency between their rp and sp responses in particular we suggest the use of a latent class approach to segment the population into two groups the first group has rp and sp responses that are internally consistent while the remaining group exhibits some form of inconsistent preferences an em algorithm is employed in an empirical application that draws on the alberta and saskatchewan moose hunting data sets used in earlier combined rp and sp exercises the empirical results suggest that somewhere between one third and one half the sample exhibits consistent preferences we also examine differences in welfare estimates drawn from the two classes

spring cleaning rural water impacts valuation and property rights institutions the brief summarizes the spring cleaning rural water impacts valuation and property rights institutions the first two rounds of spring protection occurred in january april 2005 and august november 2005 the author measure health impacts of spring protection an investment that improves source water quality the author also estimate households valuation of spring protection and simulate the welfare impacts of alternatives to the current system of common property rights in water which limits incentives for private investment spring infrastructure investments reduce fecal contamination by 66 percent but household water quality improves less due to recontamination child diarrhea falls by one quarter travel cost based revealed preference estimates of households valuations are much smaller than both stated preference valuations and health planners valuations and are consistent with models in which the demand for health is highly income elastic the author estimate that private property norms would generate little additional investment while imposing large static costs due to above marginal cost pricing private property will function better at higher income levels or underwater scarcity and alternative institutions could yield pareto improvements

specification tests for mixed demand systems with an emphasis on combining contingent valuation and revealed data abstract in a world characterized by r unrationed goods i e market goods and n r rationed goods such as most environmental goods necessary and sufficient conditions for the existence of an underlying rational preference structure are derived based on a system of mixed demand functions with complete information with incomplete information the case of a partial demand system is addressed and a test for separability is proposed the implications for testing rationality in a world characterized by combined rp and sp individual data are examined for data consistency testable conditions are derived

combining revealed and stated data to examine housing decisions using discrete choice analysis abstract this paper uses stated preference and revealed preference data separately and jointly to examine individuals housing choices in particular it combines an established revealed preference approach discrete choice analysis of actual housing purchases and a relatively new stated preference approach choice based conjoint analysis of hypothetical housing purchases to provide us with a better understanding of the factors driving housing decisions these methods are appropriately combined since they reflect the same decision process households select the dwelling that provides the best combination of attributes from the feasible set of alternatives in total this paper analyzes three data sets only actual housing purchases only hypothetical housing purchases and both types of purchases combined analysis finds that actual and hypothetical housing purchases are similar decision processes with respect to some attributes yet are dissimilar with respect to other attributes nevertheless combining the two types of data improves identification of both categories of attributes journal of economic literature classification number r21

the demand for a malaria vaccine evidence from ethiopia this study measures the monetary value households place on preventing malaria in tigray ethiopia we estimate a household demand function for a hypothetical malaria vaccine and compute the value of preventing malaria as the household s maximum willingness to pay to provide vaccines for all family members this is contrasted with the traditional costs of illness medical costs and lost productivity our results indicate that the value of preventing malaria with vaccines is about us 36 per household per year or about 15 of imputed annual household income this is on average about twice the expected household cost of illness

accounting for stochastic shadow values of time in discrete choice recreation demand models abstract in this paper a discrete choice recreation demand model that explicitly accounts for a stochastic shadow value of time function is proposed using data from a survey of san diego beach users the stochastic shadow value of time labor supply and beach choice are jointly estimated results from this joint estimation approach are compared with the familiar two step approach that estimates labor supply first and uses predicted values of time in the recreational site choice model the approaches produce markedly different welfare measures with the two step model which does not account for unobserved variability of time values predicting significantly higher values a monte carlo simulation illustrates how ignoring the stochastic nature of shadow value of time in discrete choice recreation demand models can bias model parameters and hence welfare estimates

structural benefit transfer an example using vsl estimates abstract this paper describes and illustrates a method for benefits transfer referred to as preference calibration or structural benefits transfer this approach requires selection of a preference model capable of describing individual choices over a set of market and associated non market goods to maximize utility when facing budget constraints once the structure is selected the next step involves defining the analytical expressions for the tradeoffs being represented by the set of available benefit measures these algebraic relationships are used with the benefit estimates from the literature to calibrate the parameters of the model the calibrated model then offers the basis for defining the new tradeoffs required for the policy analysis i e for transferring benefits a new application is used to illustrate the structural benefits transfer logic it involves the benefits for mortality risk reductions measured with labor market compensation a worker would accept to be willing to work with added risk the measure is usually labeled the value of a statistical life vsl our application indicates that we should not have expected differences in these measures for the economic value of risk reductions with age the calibrated estimates were not greatly different for combinations of risk levels labor supply choices wages and non wage income for older adults thus simple adjustments relying on value per discounted life year remaining seem questionable

active labor market policy evaluations a meta analysis this article presents a meta analysis of recent microeconometric evaluations of active labour market policies we categorise 199 programme impacts from 97 studies conducted between 1995 and 2007 job search assistance programmes yield relatively favourable programme impacts whereas public sector employment programmes are less effective training programmes are associated with positive medium term impacts although in the short term they often appear ineffective we also find that the outcome variable used to measure programme impact matters but neither the publication status of a study nor the use of a randomised design is related to the sign or significance of the programme estimate

combining revealed and stated preference data to estimate preferences for residential amenities a gmm approach we show how stated preference information obtained from a choice experiment and revealed preference information based on housing market transactions can be combined via generalized method of moments gmm estimation specifically we use a moment condition matching the predicted marginal willingness to pay wtp from a first stage hedonic model to the marginal wtp formula implied by the choice experiment utility function this is coupled with other moments from the choice experiment to produce gmm based estimates of parameters that reflect the strengths of each data source our application values remediation of a contaminated site in buffalo new york and we find evidence in support of estimates arising from our approach jel q51 q53

modeling recreation demand in the presence of unobservable travel costs toward a travel price model an important issue in the application of travel cost models is the construction of a travel cost variable this paper develops an econometric approach that views travel costs as an unobserved latent variable the latent variable approach utilizes indicators to capture the role of individual travel costs in recreational demand models the latent variables approach has at least two advantages over conventional approaches one the indicators can include both traditional components such as time and distance and non traditional components such as the scenic beauty second the estimation procedure results in each indicator being valued in dollar terms

empirical strategies for incorporating weak complementarity into consumer demand models abstract this article appraises existing empirical strategies for incorporating weak complementarity into consumer demand models the repackaging integrating back and discontinuity approaches are evaluated in terms of their behavioral implications and potential usefulness for applied research the appraisal suggests that the repackaging approach offers the most flexibility and tractability in the multi good demand system framework but the integrating back approach holds considerable promise in the single good context a multi good empirical comparison suggests that qualitatively similar policy inference arises from different repackaging approaches

a quantitative evaluation of payroll tax subsidies for low wage workers an equilibrium search approach abstract phelps phelps e 1994 low wage employment subsidies versus the welfare state american economic review 84 54 58 presented the case for a low wage subsidy policy since the mid 1990s france has experimented with this strategy this paper evaluates the effect of this policy on employment and also on output and welfare we construct an equilibrium search model incorporating wage posting and specific human capital investment where unemployment and the distribution of both wages and productivity are endogenous we estimate this model using french data numerical simulations show that the prevailing minimum wage allows a high production level to be reached by increasing training investment even though the optimal minimum wage is lower we show that payroll tax subsidies enhance welfare more than a reduction in the minimum wage when they are spread over a large range of wages in order to avoid specialization in low productivity jobs

possibilities for including the opportunity cost of time in recreation demand systems recreation demand modelers have attempted to identify and incorporate the opportunity cost of an individual s time in travel and on site in the model larson 1993b focused on the value of leisure time in a model where individuals face a fixed work week in this paper we examine the connection between labor supply and recreation demands and focus on conditional demand systems we illustrate that corner solution models are not needed to explain several interesting time related recreation issues

modeling discrete choices with augmented perception hurdles through creating latent perception hurdles associated with each attribute considered in a stated conjoint experiment this article describes a model that augments the conventional approach by utilizing the importance ratings provided by respondents prior to the discrete choice stage the resulting perception hurdle logit phl model has both advantages and disadvantages compared to the conditional logit cl and mixed logit models although the proposed model may not have the best within sample fit it outperforms the other two models in predicting choices in a hold out sample in addition the proposed model is also used to reveal that depending on their own characteristics and the process of the survey respondents may employ an array of different decision strategies

returns to rural electrification evidence from bhutan abstract rural electrification re is a core component of the sustainable development goals and a major focal point of the global development community despite this focus more than one billion people worldwide lack access to electricity and electrification rates need to more than quadruple to meet international goals we believe that lack of progress is partly driven by a know do gap a misalignment between academic research and the information needs of policy makers most studies measuring the impacts of electrification focus on precise estimation of a few outcomes specifically health education and productivity impacts other important impacts e g environmental have remained largely unstudied as a consequence quantifying the full set of costs and benefits of expanding electricity access is difficult and rarely done when cost benefit analyses are done they are often incomplete and conclusions are highly susceptible to unavailable or uncertain parameters we illustrate these arguments in the case of bhutan where re rates have expanded rapidly in the past few decades we show that re via grid extension had positive impacts related to fuelwood consumption education and employment but we do not find an effect on health we then use these impact estimates to conduct cost benefit analyses for the cost benefit parameters not available from our impact evaluation we transfer reasonable estimates from related contexts to acknowledge the uncertainty induced by this process we conduct monte carlo analyses and confirm that while the private npv calculations are robust to alternative parameter values the social returns are sensitive to estimates of the social cost of carbon and costs of grid operation and maintenance based on this exercise we highlight research gaps that persist and that preclude 1 careful cost benefit analysis of re more generally and 2 financial investment in the sector

assessing bankruptcy reform in a model with temptation and equilibrium default abstract a life cycle model with equilibrium default in which agents with and without temptation coexist is constructed to evaluate the 2005 bankruptcy law reform the calibrated model indicates that the 2005 reform reduces bankruptcies as seen in the data and improves welfare as lower default premia allows better consumption smoothing a counterfactual reform of changing income garnishment rate is also investigated interesting contrasting welfare effects between two types of agents emerge agents with temptation prefer a lower garnishment rate as tighter borrowing constraint prevents them from over borrowing while those without prefer better consumption smoothing enabled by a higher garnishment rate

jump starting self employment evidence among welfare participants in argentina one important concern of governments in developing countries is how to phase out large safety net programs the authors evaluate the short run effects of one possible exit strategy programs that promote self employment in argentina they provide evidence that a small fraction of beneficiaries were attracted by this program overall potential participants to self employment are more likely to be female household heads and more educated beneficiaries relative to the average jefes beneficiaries using nonexperimental methods the authors show that participation in the program does affect the labor supply of participants by reducing the probability of having an outside job especially for males and increasing the total number of hours worked but the intervention fails to produce on average income gains to participating individuals and households in the short run the fact that a small subset of former welfare beneficiaries are attracted to the program coupled with the fact that only a subset of participants younger and more educated beneficiaries and with previous self employment experience benefited from participation has important implications for this intervention to represent a viable exit strategy from welfare

assisting the transition from workfare to work a randomized experiment randomly sampled workfare participants in a welfare dependent region of argentina were given a voucher that entitled an employer to a sizable wage subsidy a second sample also received the option of skill training while a third sample formed the control group the authors analyze the effects of this scheme on participants employment and income using double difference and instrumental variables methods to deal with potential experimental biases including selective compliance with the randomized assignment the authors find that compared with the control group voucher recipients had a significantly higher probability of employment though their current incomes were no higher the impact was largely confined to women and younger workers labor supply effects appear to have been important however training had no significant impact the experiment was cost effective in reducing the government s welfare spending since take up of the subsidy by employers was low

information and bargaining in markets for environmental quality this paper explores the role of information on residential real estate prices housing transactions from 1990 formed the sample frame for surveying home buyers on their knowledge of local environmental disamenities both at the time their homes were purchased and when the survey was conducted of particular interest was home buyers knowledge of nearby landfill sites because of clustering of survey responses a sample selection model that combines transaction data with 1990 census micro data was used the results suggest that home buyers are poorly informed about disamenities and that those who are informed bid down the price of a home

household borrowing after personal bankruptcy a large body of literature has examined factors leading to filing for personal bankruptcy but little is known about household borrowing after bankruptcy this paper augments the existing literature with a comprehensive analysis of postbankruptcy borrowing using data from the survey of consumer finances we find that filers generally have more limited access to unsecured credit but borrow more secured debt after bankruptcy than comparable households that have never filed for bankruptcy filers also pay higher interest rates on all types of debt in addition as more time passes after filing credit access and borrowing costs improve however filers remain more prone than comparable nonfilers to experience financial distress accumulate less wealth and use expensive credit sources like payday loans even more than 10 years after filing

consistency in mixed demand systems contingent valuation and travel cost data in contrast to previous literature we propose a consistency test that does not impose any particular common functional form for the preference structure underlying the travel cost tc and contingent valuation cv models we derive testable consistency conditions between tc and cv data in the context of mixed demand systems when valuing changes in environmental quality these conditions are a subset of the rationality conditions the proposed consistency tests are implemented combining tc and cv data the empirical results show that it is possible to combine stated tc and cv but not revealed tc and cv data

willingness to pay for quality improvements should revealed and stated preference data be combined abstract in this article we propose theoretically consistent welfare measurement of use and nonuse values for an improvement in environmental quality with revealed and stated preference data an analytical model based on the comparative static analysis of the variation function that describes the relationship between recreation demand and dichotomous choice contingent valuation models is estimated our results show that revealed and stated data should not be combined under the same assumed preference structure unless the two decisions imply the same change in behavior induced by the quality change in addition our results indicate scope effects in willingness to pay measures estimated with stated preference data

using the travel cost method to value visits and stigma in connection with arv adherence in uganda abstractthis article uses the travel cost method to value both client visits to collect antiretroviral therapy arv and stigma which prevents arv adherence using a representative sample for uganda initiated specifically for this study we found a willingness to pay wtp valuation for visits made in the range of us 14 us 17 and a willingness to accept wta valuation of us 25 for visits missed the valuations for stigma based on a novel measure of stigma using a new estimation method were close to the valuations for visits these valuations can be used to estimate the benefits to carry out cost benefit analyses cbas of interventions aimed at increasing arv coverage and adherence

the consumption effects associated with filing for personal bankruptcy this article examines the response of food consumption to filing for personal bankruptcy in the spirit of previous work on the benefits of other social insurance programs using the panel study of income dynamics psid we find that an increase in the financial benefit to filing for bankruptcy increases the growth in food consumption in addition we find that filing under chapter 7 of the bankruptcy code provides consumption insurance while filing under chapter 13 of the bankruptcy code provides no significant consumption benefits personal bankruptcy in the united states is part of the social insurance structure provided by the federal and state governments other programs in this network include but are not limited to unemployment insurance ui temporary assistance to needy families tanf and food stamps while these latter three programs are targeted to specific groups the recently unemployed for ui and low income households for tanf and food stamps personal bankruptcy is not much like these other programs though bankruptcy reduces income uncertainty and reduces wealth uncertainty surprisingly little work has been done on the direct benefits to filing for bankruptcy this is in contrast with the growing literature on the costs of bankruptcy 1 fay hurst and white 2002 estimate the financial benefit to filing for bankruptcy which equals the debt forgiven minus any lost assets this measure is a good predictor of whether the household files for bankruptcy but it is not clear that the financial benefit is the true measure of the welfare gain from bankruptcy in fact the financial benefit is most likely an overestimate of the household s gain in the year it files for bankruptcy unlike ui or tanf bankruptcy provides no increase in money income for that period but rather increases net of debt income this change is felt over the household s lifetime and filers will most likely smooth this effect over multiple years because households cannot file for bankruptcy again for six years further using the financial benefit makes it difficult to compare results against the

strategic or nonstrategic the role of financial benefit in bankruptcy i introduction personal bankruptcy rates have increased at an annual rate of 3 9 since 1990 from about 718 thousand non business bankruptcies in 1990 to about 1 5 million in 2010 partly as a response to this increase the congress passed the bankruptcy abuse prevention and consumer protection act bapcpa of 2005 the largest overhaul of bankruptcy laws since 1980 although recent data are too sparse to determine the longer term effectiveness of the law we know that there was a spike in bankruptcy filings in 2005 just before the law took effect on october 17 2005 and a corresponding decline in 2006 since then bankruptcies have continued to rise reaching a level of about 1 5 million in 2010 the same level as in 2004 the bankruptcy rate has also begun to creep up to the earlier levels one of the major purposes of the new bankruptcy law was to cut down on abusive or fraudulent uses of the bankruptcy system or in other words strategic use of the law therefore it is important to understand the motivations of consumers who file for bankruptcy what constitutes strategic use of bankruptcy law and how widespread is its incidence in the literature there is no clear definition of what constitutes a strategic bankruptcy filing we shall consider strategic behavior to be a conscious decision to benefit from bankruptcy law to make this tractable consider a simple two period model of decision making in the first period consumers receive a noisy signal of experiencing a financial shock in the second period based on this signal consumers may update their probability of an adverse shock and choose their debt level in the second period the shock is realized and consumers decide whether to file for bankruptcy or not a strategic consumer is one who in the first period chooses her debt level after conditioning on the signal that is a strategic consumer takes on debt after accounting for the chance of filing for bankruptcy in other words a strategic consumer is one who is fully rational and takes decisions to maximize her benefit a nonstrategic consumer is one who chooses debt level without conditioning on the signal he plans to repay his debt in the absence of adverse events such a consumer is myopic and may be exhibiting rational inattention as described below consistent with this view we may distinguish between strategic and nonstrategic behavior by testing whether consumers make their debt and filing decision jointly or not strategic behavior is consistent with a joint decision whereas nonstrategic behavior is not in terms of empirical strategy this is implemented by testing whether financial benefit is endogenous to the filing decision or not our test is different from the one in the study by fay hurst and white 2002 henceforth fhw in that approach a positive relationship between filing for bankruptcy and financial benefit from filing ceteris paribus is taken as evidence of strategic behavior and a positive relationship between filing for bankruptcy and adverse events such as divorce health shocks employment shocks etc is taken as evidence of nonstrategic behavior using data from the panel study of income dynamics psid fhw show that financial benefit is positively and significantly related to the filing decision and after controlling for financial benefit adverse event variables do not affect the bankruptcy decision except for a marginally significant positive effect of divorce 1 this simple empirical relationship between bankruptcy filing and financial benefit does not consider more realistic relationships among financial benefit adverse events and strategic behavior for example financial benefit from filing may go up due to adverse events regardless of whether a consumer is trying to abuse bankruptcy law or not that is financial benefit goes up when a consumer consciously increases unsecured debts before filing consistent with strategic behavior and it also goes up when she uses unsecured debt e

averting behavior in the presence of public spillovers household control of nuisance pests this paper empirically imple ments an averting behavior model for gypsy moth control explicitly recognizing the joint pri vate and public spillover motivations for con trol the results demonstrate that averting be havior models can capture complex behavioral influences suggesting that such models can be extended beyond health related applications the model yields a reduced form parameter which cannot be identified using actual behavior data alone a method combining models of ac tual behavior and contingent behavior is piro posed as a way to directly measure the produc tion and preference effects jel q23

combining contingent valuation and travel cost data for the valuation of non market goods the travel cost method tcm has long been used to infer the economic value of nonmarket resources and public goods more recently contingent valuation cvm survey methods have gained popularity for eliciting these values here cvm survey responses are combined with tcm data on actual market behavior to estimate jointly both the parameters of the underlying utility function and its corresponding ordinary demand function this is a prototypical empirical example of a new modeling strategy variants of which should prove useful in many applications especially where reliance on a single valuation method is undesirable

discrete choice survey experiments a comparison using flexible methods abstract this study investigates the convergent validity of discrete choice contingent valuation cv and contingent rating ranking cr methods using flexible econometric methods our results suggest that cv and cr can produce consistent data achieve convergent validity when respondent s preferred choices and the same changes in environmental quality are considered we also find that cr models that go beyond modeling the preferred choice and include additional ranks cannot be pooled with the cv models accounting for preference heterogeneity via random coefficient models and their flexible structure does not make rejection of the hypothesis of convergent validity less likely but instead rejects the hypothesis to about the same degree or perhaps more frequently than fixed parameter models commonly used in the literature

race ethnicity and credit card marketing there is a vast literature on discrepancies in consumer credit related to race and ethnicity i explore a pattern that was first identified in aggregate data by han keys and li 2011 in their study of credit access blacks were approximately 27 less likely to receive offers from credit card lenders during the sample period even after controlling for variables such as credit history household income and local economic conditions hispanics were 17 less likely to receive an offer after including controls the discrepancy is robust to lender specific regressions and the inclusion of a large number of explanatory variables my findings imply that marketing is an important area for analysis of discrimination in consumer credit due to the likely need for confidential information in further analysis investigation by an appropriate regulatory agency such as the consumer financial protection bureau would be useful

personal bankruptcy and credit supply and demand this paper examines how personal bankruptcy and bankruptcy exemptions affect the supply and demand for credit while generous state level bankruptcy exemptions are probably viewed by most policy makers as benefiting less well off borrowers our results using data from the 1983 survey of consumer finances suggest that they increase the amount of credit held by high asset households and reduce the availability and amount of credit to low asset households conditioning on observable characteristics thus bankruptcy exemptions redistribute credit toward borrowers with high assets interest rates on automobile loans for low asset households also appear to be higher in high exemption states

estimating the private benefits of vaccination against cholera in beira mozambique a travel cost approach abstract this paper reports the results of the first study that estimates households private demand for cholera vaccines using the travel cost method we take advantage of an unusual natural experiment in january 2004 more than 41 000 residents from various locations in beira mozambique received two doses of oral cholera vaccine free of charge during the first vaccination trial to test its effectiveness in an endemic cholera zone of africa about 30 000 people participated from outside the target zone resulting in long queues and an average waiting time of about 85 min per dose we estimated travel cost models of the revealed demand for cholera vaccines among households informed of the trial using information collected in in person interviews conducted during the summer of 2005 to explore households participation in the trial we used standard and zero inflated household count models for all household members and dichotomous choice models for the head of the household our analysis shows that the quantity of vaccines obtained by households and the likelihood of participation decreased as travel cost in time and transport expenses rose our best estimates of per capita willingness to pay for the two required doses of cholera vaccine are about 0 85 usd these estimates are sensitive to the assumed value of time spent acquiring vaccines

who gets credit after bankruptcy and why an information channel abstract conventional wisdom holds that individuals find it difficult to obtain new credit post bankruptcy using credit bureau data we test this hypothesis and show that more than 90 of bankrupt individuals receive credit shortly after filing individuals with good credit history prior to filing have reduced credit availability after bankruptcy while those with ex ante low credit quality receive more credit we show that credit supplied to low quality individuals is severely curtailed during the financial crisis we also find that the default probability on new debt increases after bankruptcy especially among individuals with high ex ante credit score these findings are consistent with an information channel in which bankruptcy reveals new information about a borrower s credit quality

cost benefit analysis and mammographic screening a travel cost approach abstract this study describes the methodology and presents preliminary results of an economic appraisal of a program to use mobile mammographic screening units in rural areas of australia the benefits of the project are measured using the travel cost method since mammograms are a binary good conventional welfare analysis must be modified and discrete choice models used to estimate the demand for screening the results suggest that the level of welfare benefits depends on the distance a town is from the nearest fixed screening unit in the 10 towns studied the economic benefits of mobile screening outweighed the economic costs if a rural town is situated 29 km or more from a fixed mammographic screening unit

can entrepreneurial activity be taught quasi experimental evidence from central america summary business training is a widely used development tool yet little is known about its impact we study the effects of such a business training program held in central america to deal with endogenous selection into the training program we use a regression discontinuity design exploiting the fact that a fixed number of applicants are taken into the training program based on a pre training score business training significantly increases the probability that an applicant to the workshop starts a business or expands an existing business results also suggest gender heterogeneity as well as the presence of financial constraints

what works a meta analysis of recent active labor market program evaluations we summarize the estimates from over 200 recent studies of active labor market programs we classify the estimates by type of program and participant group and distinguish between three different post program time horizons using regression models for the estimated program effect for studies that model the probability of employment and for the sign and significance of the estimated effect for all the studies in our sample we conclude that 1 average impacts are close to zero in the short run but become more positive 2 3 years after completion of the program 2 the time profile of impacts varies by type of program with larger average gains for programs that emphasize human capital accumulation 3 there is systematic heterogeneity across participant groups with larger impacts for females and participants who enter from long term unemployment 4 active labor market programs are more likely to show positive impacts in a recession

effectiveness of active labor market tools in conditional cash transfers programs evidence for argentina summary this paper examines the impact of the program seguro de capacitacion y empleo sce implemented to provide support in skills upgrading job seeking and job placement to eligible beneficiaries of the argentinian conditional cash transfer program plan jefes the sce is an example of a growing trend observed in latin america where labor activation components have been increasingly included into cash transfers programs to support beneficiaries in finding more stable income opportunities despite this growing trend not enough is known regarding the effectiveness of these components especially on job quality in this context this paper sheds light on whether the provision of a comprehensive package of active labor market measures contributes to a successful labor market integration of cash transfers beneficiaries taking advantage of the panel structure of the permanent household survey and exploiting the time variation in the assignment of the program as identification strategy we apply difference in difference estimators to measure the impact on a number of labor market indicators we find that the program affects positively the job quality of participants by increasing the probability of having a formal job and raising hourly wages moreover the intervention is associated with a lower probability of having a low paid job and working an excessive number of hours these effects are however not homogeneous across all groups of participants while the program is more successful among the younger beneficiaries it does not contribute to an improvement in the labor market conditions of female beneficiaries who in fact are the majority of sce participants our results suggest that reducing dependency on monetary transfers through programs such as the sce that are rich in activation components is beneficial for participants labor market trajectories and therefore it constitutes a satisfactory exit strategy to more universal cash transfer programs

augmenting travel cost models with contingent behavior data this paper proposes contingent behavior survey questions as a valuable supplement to observed data in travel cost models of non market demand for recreational resources a set of observed and contingent behavior results for each survey respondent allows the researcher to control for individual heterogeneity by taking advantage of panel data methods when exploring the nature of respondent demands the contingent scenarios also provide opportunities to a test for differences between observed and contingent preferences and or b assess likely demands under conditionsbeyond the domain of observed variation in costs or resource attributes most importantly contingent scenarios allow the researcher to imposeexogenously varying travel costs exogenous imposition of travel costs together with panel methods reduces the omitted variables bias that plagues observed data travel cost models of recreational demand using a convenience sample of data for illustrative purposes we show how to estimate the demand for recreational angling by combining observed and contingent behavior data we begin with simple naive pooled poisson models and progress to more theoretically appropriate fixed effects panel poisson specifications

an empirical analysis of personal bankruptcy and delinquency this article uses a new dataset of credit card accounts to analyze credit card delinquency personal bankruptcy and the stability of credit risk models we estimate duration models for default and assess the relative importance of different variables in predicting default we investigate how the propensity to default has changed over time disentangling the two leading explanations for the recent increase in default rates a deterioration in the risk composition of borrowers versus an increase in borrowers willingness to default due to declines in default costs even after controlling for risk composition and economic fundamentals the propensity to default significantly increased between 1995 and 1997 standard default models missed an important time varying default factor consistent with a decline in default costs debt issued by consumers is an understudied asset class there has been particularly little academic study of recent trends in default on this debt between 1994 and 1997 the number of personal bankruptcy filings in the united states rose by about 75 the 1 35 million filings in 1997 represented well over 1 of u s households delinquency rates on credit cards rose almost as sharply federal reserve bank of cleveland 1998 the resulting losses to lenders amounted to a sizable fraction of the interest payments they collect potentially raising the average cost of credit these trends in default both in bankruptcy and delinquency are especially surprising in light of the strong economy over the period they provide an unusually rich source of variation to test the stability of models that forecast personal default and of credit risk models more generally there are two leading explanations for these trends first the risk composition of borrowers might have worsened under the risk effect less

valuing public goods a comparison of survey and hedonic approaches although the theory of public goods has progressed rapidly since paul samuelson s seminal article the empirical measurement of the value of demand for public goods only recently has received increased attention perhaps the best known and most widely accepted empirical approach has been the use of hedonic prices wherein for example it is assumed that either wages or housing values reflect spatial variation in public good characteristics of different communities this indirect approach based on theoretical work of charles tiebout kelvin lancaster sherwin rosen and others has proven quite successful among public goods or bads which have been valued using the hedonic approach are climate i hoch air pollution robert anderson and thomas crocker d harrison and d rubinfeld social infrastructure r cummings et al and other community characteristics such as noise level j nelson and ethnic composition ann schnare an alternative approach is to directly ask households or individuals to state their willingness to pay for public goods using survey techniques despite arguments that strategic bias will invalidate survey results there exists the need for an alternative to the hedonic approach as an example consider the case of a remote and unique scenic vista valuable to recreators which is threatened by air pollution from a proposed coal fired plant a typical situation in the western united states although it is possible in principle to impute the value of clean air and visibility from the relative decline in local visitation which might follow construction of a power plant information on the value of visibility at the site is needed prior to construction for socially optimal decision making on plant location and pollution control equipment the hedonic approach is unavailable both because the scarcity of local population as opposed to recreators makes use of wage or property value data impossible and because scenic vistas may themselves be unique for these reasons a randall et al first applied survey methods for valuing visibility and other environmental effects of large coal fired power plants in the four corners region of new mexico since this initial application the survey approach has been widely used to value environmental commodities where market data for hedonic analysis is difficult to acquire see for example brookshire ives and schulze rowe et al brookshire et al other early attempts to value public goods using the survey approach include r davis peter bohm and j hammack and g brown although results of using the survey approach for estimating the value of public goods appear to be internally consistent replicable and consistent with demand theory see schulze et al little work on external validation has been reported thus the purpose of this paper is to report on an experiment designed to validate the survey approach by direct comparison to a hedonic property value study the los angeles metropolitan area was chosen for the experiment because of the well defined air pollution problem and be assistant professor university of wyoming assistant professor university of missouri rolla associate professor university of wyoming and professor university of wyoming respectively the research reported here was funded under a grant methods development for assessing air pollution control benefits from the u s environmental protection agency we would like to give special thanks to alan carlin and shelby gerking for their helpful suggestions and contributions additional helpful comments were received from a myrick freeman iii john tschirhart and james murdoch all conclusions are of course our sole responsibility

the household bankruptcy decision personal bankruptcy filings have risen from 0 3 percent of households per year in 1984 to around 1 35 percent in 1998 and 1999 transforming bankruptcy from a rare occurrence to a routine event lenders lost about 39 billion in 1998 due to personal bankruptcy filings but economists have little understanding of why households file for bankruptcy or why filings have increased so rapidly until very recently studying the household bankruptcy decision was very difficult because no household level data set existed that included information on bankruptcy filings in this paper we use new data from the panel study of income dynamics which includes information on bankruptcy filings to estimate a model of households bankruptcy decisions we find support for the strategic model of bankruptcy which predicts that households are more likely to file when their financial benefit from filing is higher our model predicts that an increase of 1 000 in households financial benefit from bankruptcy would result in a 7 percent increase in the number of bankruptcy filings our model also predicts that if the 1997 national bankruptcy review commission s proposed changes in bankruptcy exemption levels were implemented there would be a 16 percent increase in the number of bankruptcy filings each year but if the 100 000 cap on homestead exemptions recently passed by the u s senate were adopted our model predicts that there would be only a negligible effect on the number of filings we find little support for the nonstrategic model of bankruptcy which predicts that households file when adverse events occur which reduce their ability to repay finally controlling for state and time fixed effects our model shows that households are more likely to file for bankruptcy if they live in districts with higher aggregate filing rates

a joint latent class model combining likert scale preference statements with choice data to harvest preference heterogeneity in addition to choice questions revealed and stated choices preference surveys typically include other questions that provide information about preferences preference statement data include questions on the importance of different attributes of a good or the extent of agreement with a particular statement the intent of this paper is to model and jointly estimate preference heterogeneity using stated preference choice data and preference statement data the starting point for this analysis is the belief that the individual has preferences and both his her choices and preference statements are manifestations of those preferences our modeling contribution is linking the choice data and preference statement data in a latent class framework estimation is straightforward using the e m algorithm even though our model has hundreds of preference parameters our estimates demonstrate that 1 within a preference class the importance anglers associate with different green bay site characteristics is in accordance with their responses to the preference statements 2 estimated across class utility parameters for fishing green bay are affected by the preference statement data 3 estimated across class preference statement response probabilities are affected by the inclusion of the choice data and 4 both data sets influence the number of classes and the probability of belonging to a class as a function of the individual s type

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
