an experimental validation of hypothetical wtp for a recyclable product using a within subject experiment we compare hypothetical andreal willingness to pay wtp for an improvement in therecyclability of a product subjects are faced with a real paymentscenario after they have responded to a hypothetical question contrary to most of the results obtained in similar studies at apopulation level there are no significant median differencesbetween actual and hypothetical stated values of wtp however within subject comparisons between hypothetical and actual valuesindicate that subjects stating a low high hypothetical wtp tendto underestimate overestimate the value of their actualcontributions

economics of farmer early retirement policy we estimate the structural effects costs and potential efficiency gains that might arise from the introduction of an early retirement scheme for farmers in northern ireland using data from the farm business survey and a separate survey of 350 farmers aged between 50 and 65 modelling results suggest that farm scale is a significant determinant of profit per hectare but that the age of the operator is not the economic gains from releasing land through a scheme were conditional on transfers bringing about significant farm expansion and changes in land use when these conditions were satisfied pensions payments of only about one third the statutory maximum could be justified survey responses indicated that participation in the scheme would bring forward farmers retirement age by an average of 4 years moreover deadweight payments would equate to about 23 of potential total expenditure overall the economic case for the introduction of an early retirement scheme to northern ireland is judged to be weak

assessing the consumers willingness to adopt a prepayment metering system in nigeria abstract despite the rising popularity in the adoption and usage of prepayment meters little is still known about the drivers of its adoption we examine the willingness to adopt prepayment metering ppm for a sample of nigerian households that were not prepayment users double hurdle models were estimated to account for households decisions concerning billing system switching behaviour and households willingness to pay wtp the estimated results revealed that decisions to adopt a prepayment meter are significantly affected by current electricity spending current billing method and the split incentive problem whereas current electricity spending significantly increased the tendency to adopt ppm the split incentive problem reduced the probability of adoption although unmetered consumers were more likely to express a willingness to adopt a ppm system than post paid customers they did not intend to pay a significantly higher amount to obtain the prepayment service income did not play a significant role in decision making concerning ppm adoption and the corresponding wtp amount these results cast doubt on the validity of the widely held belief that low income may be responsible for ppm adoption reflecting the widespread usage of ppm by low income households

the disparity between willingness to accept and willingness to pay measures of value psychologists have long argued that people are much more averse to a loss than attracted to an equivalent gain this behavior termed loss aversion has been formalized by kahneman and tversky 1979 in their reformulation of expected utility theory prospect theory in prospect theory the utility function is replaced by a value function that evaluates changes in income from the current level increases in income are weighted by a relatively small marginal utility decreases in income are weighted by a much larger marginal utility in effect the value function implies that a kink in the relationship between utility and income occurs at the initial income or reference point and that the slope of the utility function for losses in income is steeper than it is for gains in a recent paper knetsch and sinden 1984 report a series of experiments that demonstrate the existence of a large disparity between willingness to accept wta and willingness to pay wtp measures of value they argue that the psychological theory of loss aversion explains this difference economic theory would suggest that individuals who exhibit a large disparity between wta and wtp are perhaps underperceiving the value of gains or overperceiving the value of losses are behaving in an irrational manner and will consequently achieve a lower level of well being than if they behaved in a true utility maximizing manner this would in contrast to loss aversion usually imply near equal values for wta and wtp see willig 1976 further documentation of a larger than expected disparity between wta and wtp has been obtained in surveys asking for the value of a variety of public goods for example cummings brookshire and schulze 1986 document six

shirking and sorting in a political market with finite lived politicians this paper analyzes principal agent slack in the context of a political market composed of voters challengers and incumbents the introduction of a last period via finite livedness in combination with voters imperfect information about politicians preferences causes time varying shirking behavior on the part of politicians political markets eventually sort out those politicians with significantly deviant policy preferences potentially providing a solution to the last period problem and enabling politicians to make credible commitments in the extreme sorting can insure that it is not worthwhile for potential shirkers to run for office a systematic relationship between political shirking and number of terms in office may exist and depends on how quickly sorting takes place we show that evidence of little if any shirking is quite consistent with politicians having diverse and strongly held policy preferences in addition if sorting is a significant feature of political markets cross sectional studies will tend to oversample little and non shirking politicians compared to longitudinal studies reinterpretations of existing empirical work are also discussed

why farmers quit a county level analysis we identify the effects of alternative explanatory variables on the propensity of u s farmers to cease farming with a particular emphasis on understanding the roles of off farm employment and federal farm program payments conventional ordinary least squares analysis using all counties suggests that off farm employment has no statistical effect on the net number of farmers quitting between 1987 and 1997 ceteris paribus a more refined analysis which separates counties losing farmers from those that gained farmers reveals subtle and less clear cut effects of off farm employment and federal program payments on farm exits copyright 2001 oxford university press

political economy of public policies insights from distortions to agricultural and food markets the agricultural and food sector is an ideal case for investigating the political economy of public policies many of the policy developments in this sector since the 1950s have been sudden and transformational while others have been gradual but persistent this paper reviews and synthesizes the literature on trends and fluctuations in market distortions and the political economy explanations that have been advanced based on a rich global data set covering a half century of evidence on commodities countries and policy instruments the paper identifies hypotheses that have been explored in the literature on the extent of market distortions and the conditions under which reform may be feasible

effect of distance of transportation on willingness to pay for food abstract consumers interest in locally produced foods is increasing hence there is a need to decipher and quantify consumers desire for local foods and understand the underlying causes of this demand more specifically we examine in this paper the issue of distance of transportation and its impact on consumer preferences we investigate how consumers willingness to pay wtp for food varies with the distance the food traveled results from non hypothetical second price auctions indicate that average wtp is falling in distance traveled indicating a preference for local production results also indicate that the marginal value of a mile traveled depends on the type of food studied apples vs wine socio demographic characteristics perceptions of freshness taste and food safety as well as support of local economy impact wtp for local foods

promoting local foods in small island states the role of information policies ensuring the success of agriculture is at the heart of food security and it is necessary to examine strategies that tackle agricultural development through the production and consumption of sustainable food products one way to increase food security in small island states is to develop local food sectors by increasing consumers awareness about local products with sustainable characteristics we designed an economic experiment to assess consumers willingness to pay wtp for yams with sustainable characteristics the origin the intrinsic quality of an alternative variety and the mode of production the results showed that labelling significantly changes consumers valuation of the different yam profiles consumers wtp for local yams 2 85 kg 1 was significantly higher than for imported yams 1 80 kg 1 while the organic mode of production derives a significant premium if information on production methods has been disseminated the results also suggested that organoleptic characteristics of new varieties should not be overlooked we conclude on how the labelling strategy could be facilitated through a policy targeting the development of the local food sector

the eu budget battle assessing the trade and welfare impacts of cap budgetary reform abstract there is a paucity of quantitative impact assessments of the sectorial and macroeconomic impacts of cap budget reform for eu member states to fill this gap the current study employs a sophisticated agricultural variant of the gtap model to evaluate the recently agreed cap spending limits for the financial period 2014 2020 as well as a more radical 50 cut to the cap budget proposed by the uk government the study incorporates methodological innovation in terms of the modelling of cap budgetary mechanisms furthermore official eu auditing statistics are employed to i greatly improve the existing representation of agricultural support payments in the gtap benchmark data and ii implement a detailed contemporary cap baseline for member states to capture both the decoupled coupled split of support payments and the distribution of support across both pillars in general cap expenditure cuts have muted impacts on eu and world agricultural markets whereas changes in net transfer payments have implications for real income and macro trade balances in eu member states this observation is particularly pertinent when assessing conciliatory reductions in the uk rebate in exchange for deeper cap budget cuts

the causes of order effects in contingent valuation surveys an experimental investigation contingent valuation researchers have found that the hypothetical values respondents place on a nested sequence of environmental goods are sensitive to the order in which the goods are presented typically the smallest bundle of goods is valued more highly if presented first than if following more comprehensive bundles such effects appear even when each bundle is valued from an exclusive list or as an alternative to any other so that income and substitution effects are controlled we conduct lab experiments where participants are asked to value sequences of nested goods for purchase from an exclusive list using an incentive compatible becker degroot marschak mechanism we test whether order effects occur in valuation for a induced value goods b actual private goods and c identical private goods that are to be donated to charities we find significant order effects when the goods are valued for own use but not when they are valued for donation

signaling through obstruction obstruction is a time honored tradition in legislative politics in many cases obstruction can be foreseen to be ultimately unsuccessful and in some of these cases purely costly even to the obstructor in this article i construct a model of obstruction in which the individual obstruction of a fait accompli policy proposal is potentially informative precisely and ironically because it is inefficient the theory based on the legislators reelection motivations offers comparative static predictions about the frequency and length of obstruction as a function of the individual characteristics of the legislator and his or her electoral setting including the legislator s value for reelection the appeal of the legislator s challenger the legislator s individual specific seniority competence and or valence and the visibility of the legislator s obstruction efforts to the voter finally the theory illustrates the potential for transparency of legislators individual actions to be strictly welfare reducing even in the absence of pandering

severing the electoral connection shirking in the contemporary congress studies of representation focusing on legislative shirking tend to offer an interesting tension when the opportunity presents itself it seems that exiting members do not change their votinq behavior ideological shirking but do reduce their effort level by voting less participatory shirking our analysis avoids the pitfalls of prior studies by defining a simple quasi experimental research design contrasting those certain that they are seeking reelection with those sure that they are departing the house for the102nd 103rd and 104th congresses 1991 1996 we measure changes in ideology and participation using all roll call votes in the last six months of election years controlling for possible member selection effects and short term influences and show that legislators are disposed toward ideological and participatory shirking while selection effects are unimportant thus we reconcile results seemingly at odds and suggest that policies affecting member turnover such as term limits can interfere with representation a fundamental issue concerning political representation is the extent to which the necessity of reelection constrains officeholders if incumbents plan to retire thus freeing themselves of their electoral shackles or if they pursue higher office and face a distinct constituency will they behave differently or do members continue to behave in the same manner even in the absence of an electoral connection to the districts they represent answers to such questions have important implications for how we understand and model the representative process additionally they have ramifications for the likely impact of public policy choices that affect member turnover rates such as the imposition of term limits on the political system a primary means of drawing inferences regarding shirking which we simply define as legislator behavior that differs from what would be observed given perfect monitoring and effective punishment by constituents is to determine if politicians change their behavior when electoral discipline is removed most notably scholars examine members actions during their last period in office on the grounds that those voluntarily departing can behave according to a distinct set of preferences even if they run afoul of their districts or of their electoral coalitions empirical results on final period behavior are voluminous and sometimes contradictory bender and lott 1996 nevertheless two general inferences seem to have gathered support first there is little evidence for shirking in terms of vote choice ideological shirking while as we will discuss shortly there are a variety of potential explanations for such nonfindings one intuitive and frequently offered reason is that they reflect member specific selection effects this implies that

a simultaneous approach to the estimation of risk aversion and the subjective time discount rate in this paper we analyze a sample of 1832 individuals who responded to six randomly generated lottery questions that differ with respect to chance prize and the timing of the draw using a model that explicitly allows for consumption smoothing we obtain an estimate of relative risk aversion of 82 instead assuming consumption to be immediate gives an estimate of 2 close to what is traditionally reported while a model of full asset integration gives estimates higher by several orders of magnitude our results show that estimated risk aversion is sensitive to the assumptions made with respect to the consumption profile and that it is possible to determine the level of asset integration endogenously the average subjective time discount rate which includes a preference for the present equals 6 percent per month it is found that both parameters vary strongly over individuals and that the variation can be explained by income age gender and entrepreneurship consistent with the majority of previous evidence

understanding the consequences of consequentiality testing the validity of stated preferences in the field this study pursues the external validation of stated preference methods by comparing survey responses from verified voters with the outcome of a parallel public referendum on a conservation and preservation program to be funded by a local property tax surcharge the majority of respondents were unaware of the upcoming referendum and the experimental design allows us to control for referenda related information effects as well as respondents perceptions regarding the consequentiality i e the potential policy impact of their survey votes we find the survey under predicts yes referendum votes at the precinct level these differences go away however if we focus only on respondents who perceived their survey vote to be consequential negative hypothetical bias among inconsequential survey respondents is also evident in the estimation of willingness to pay and controlling for consequentiality increases construct validity

are choice experiments incentive compatible a test with quality differentiated beef steaks this study compares hypothetical and nonhypothetical responses to choice experiment questions we test for hypothetical bias in a choice experiment involving beef ribeye steaks with differing quality attributes in general hypothetical responses predicted higher probabilities of purchasing beef steaks than nonhypothetical responses thus hypothetical choices overestimate total willingness to pay for beef steaks however marginal willingness to pay for a change in steak quality is in general not statistically different across hypothetical and actual payment settings

how reliable are meta analyses for international benefit transfers meta analysis has increasingly been used to synthesise the environmental valuation literature but only a few test the use of these analyses for benefit transfer these are typically based on national studies only however meta analyses of valuation studies across countries are a potentially powerful tool for benefit transfer especially for environmental goods where the domestic literature is scarce we test the reliability of such international meta analytic transfers and find that even under conditions of homogeneity in valuation methods cultural and institutional conditions across countries and a meta analysis with large explanatory power the transfer errors could still be large further international meta analytic transfers do not on average perform better than simple value transfers averaging over domestic studies thus we question whether the use of meta analysis for practical benefit transfer achieves reliability gains justifying the increased effort however more meta analytic benefit transfer tests should be performed for other environmental goods and other countries before discarding international meta analysis as a tool for benefit transfer

gasoline demand revisited an international meta analysis of elasticities meta analysis is used to determine if there are factors that systematically affect price and income elasticity estimates in studies of gasoline demand four econometric models are estimated using long run and short run price and income elasticity estimates from previous studies as the dependent variables explanatory variables include functional form lag structure time span national setting estimation technique and other features of the model structure elasticity estimates are found to be sensitive to the inclusion or exclusion of some measure of vehicle ownership static models appear to overestimate short run elasticities underestimate long run price elasticities but pick up the full long run income responsiveness there is variation in the elasticity of demand across countries especially in the short run and gasoline demand appears to be getting more price elastic and less income elastic over time

an inferred valuation method although estimates of people s values for public goods are often needed to conduct cost benefit analysis existing value elicitation methods are prone to a number of well documented biases we argue that some of these biases result because people derive utility from the act of saying they are willing to pay for a good to counteract this phenomenon we consider an approach that asks people to predict or infer others values for a good instead of asking people to state their own value both a conceptual model and results from a laboratory experiment lend support for the new approach

are consumers in developing countries willing to pay more for micronutrient dense biofortified foods evidence from a field experiment in uganda vitamin a deficiency is a major health problem in africa and in many other developing countries biofortified staple crops that are high in pro vitamin a have the potential to reduce the prevalence of vitamin a deficiency using a choice experiment with the real product in uganda we quantify the magnitude of the premium or discount in consumers willingness to pay wtp that may be associated with it results suggest that taste plays an important role in consumer acceptance and the provision of nutrition information does translate into substantial premiums for the biofortified variety there is a substantial hypothetical bias in the wtp for the new varieties and while cheap talk mitigates this bias it does not eliminate it

estimating consumer willingness to supply and willingness to pay for curbside recycling we estimate the willingness to pay for curbside recycling based on a contingent valuation survey of 600 residents of a large southeastern united states city the best estimate of willingness to pay for curbside recycling is 2 29 month after adjustment for hypothetical bias we also report the results of a field experiment designed to test the effectiveness of explicit monetary incentives and communication appeals to influence the decision to recycle and the quantity of materials to recycle while households respond to the monetary cost of recycling the effects of the token ex ante incentives and appeals appear to be small jel d61 q21

reliability and predictive validity of contingent values does the nature of the good matter abstract because the contingent valuation mechanism cvm elicits verbal reports of maximum willingness to pay and not actual willingness to pay analysts have expressed doubts about the reliability and validity of contingent values for commodities such as environmental amenities this skepticism is usually attributed to the amorphous nature of the commodity and to peoples lack of familiarity or experience however our comparison of two commodities which lie at polar extremes of the private good public good continuum suggests that the nature of the good may have little influence on the reliability and predictive validity of the cvm instead aspects of the cvm itself e g explicit payment obligation may be more important for high intention behavior consistency

political accountability and sequential policymaking abstract we develop a model of political accountability with sequential policymaking when a bureaucrat s actions are transparent his overseer faces a political time inconsistency problem she is tempted to revise her retention rule in the middle of the policymaking process as a result the bureaucrat s equilibrium behavior overemphasizes later tasks if the overseer knows the technology by which policies translate into outcomes then she can eliminate these distortions using task specific budget caps however if the overseer is uncertain about this technology such budget caps introduce ex post inefficiency when uncertainty is sufficiently large and consequential the overseer prefers an institutional environment with a fungible budget and no transparency such an environment allows the overseer to exploit the bureaucrat s expertise though at the cost of weaker overall incentives

is hypothetical bias a universal phenomenon a multinational investigation a concern with the contingent valuation method cvm is the finding that hypothetical and real statements of value often differ we test whether hypothetical bias broadly defined is independent of location by comparing real and hypothetical votes on a dichotomous choice referendum in china france indiana kansas and niger we find significant differences in hypothetical bias across locations and reject the hypothesis that hypothetical bias is independent of location as opposed to the typical finding reported in the literature subjects in niger significantly understated their willingness to pay in the hypothetical referendum

what s to know about hypothetical bias in stated preference valuation studies abstract hypothetical bias arises in stated preference valuation studies when respondents report a willingness to pay wtp that exceeds what they actually pay using their own money in laboratory or field experiments although this bias is not found in all stated preference surveys hypothetical wtp typically exceeds the actual value by a factor of two to three unfortunately there is no widely accepted general theory of respondent behaviour that explains hypothetical bias therefore two meta analyses are reviewed to test current hypotheses regarding the causes of this overstatement of wtp and the associated recommendations to mitigate the bias suggestions for future research are made including the development of a general theory

risky sports and the value of safety information abstract we develop a theoretical account of how athletes engaged in risky sports value safety information based on our model we postulate that the demand value of such information rises with wealth and exposure and declines with the athlete s appetite for risk we use survey data from a sample of backcountry skiers to empirically test these predictions the high degree of self control over exposure makes these athletes a well suited population to study the demand value of safety information caution is warranted in the empirical analysis as unobserved factors may jointly affect the athlete s perceived risk and his willingness to pay for obtaining safety information we use a recursive two stage estimation approach to account for endogeneity concerns the empirical results are supportive of our theoretical predictions and suggest that variations in athletes demand for safety information can be explained by personal beliefs about risk exposure and deliberate risk taking

the development and estimation of a latent choice multinomial logit model with application to contingent valuation we offer a new approach to investigate hypothetical bias in contingent valuation using a latent choice multinomial logit model to develop this model we extend dempster laird and rubin s 1977 work on the expectations maximization algorithm to the estimation of a multinomial logit model with missing information on category membership our model can be used to determine within choice heterogeneity using data on the preservation of saginaw wetlands in michigan we find evidence for two types of yes responders in the data we suggest that one set of yes responders consists of yea sayers who answer yes to the hypothetical question but are less likely to pay the bid amount if it were real we suggest that the second group of respondents does not suffer from hypothetical bias and are more likely to pay the bid amount if it were real even if the connection to hypothetical bias cannot be made our method can be used in sensitivity analyses of willingness to pay estimates

what experimental protocol influence disparities between actual and hypothetical stated values preferences elicited in hypothetical settings have recently come underscrutiny causing estimates from the contingent valuation method to bechallenged due to perceived hypothetical bias given that the receivedliterature derives value estimates using heterogeneous experimentaltechniques understanding the effects of important design parameters onthe magnitude of hypothetical bias is invaluable in this paper we addressthis issue statistically by using a meta analysis to examine data from 29experimental studies our empirical findings suggest that on averagesubjects overstate their preferences by a factor of about 3 in hypotheticalsettings and that the degree of over revelation is influenced by thedistinction between willingness to pay and willingness to accept publicversus private goods and several elicitation methods

short and long run credit constraints in french agriculture a directional distance function framework using expenditure constrained profit functions this empirical application investigates the eventual presence of credit constraints using a panel of french farmers the credit constrained profit maximization model proposed by fare grosskopf and lee is extended in three ways first we rephrase the model in terms of directional distance functions to allow duality with the profit function second we model credit constraints in the short run and investment constraints in the long run using short and long run profit functions third we lag the expenditure constraint one year to account for the separation between planning and production we find empirical evidence of credit and investment constraints financially unconstrained farmers are larger perform better and seem to benefit from a virtuous circle where access to financial markets allows better productive choices

the effects of congressional appropriation committee membership on the distribution of federal research funding to universities i introduction in 1994 members of the republican party pledged to seek legislation to impose term limits on members of congress this pledge stemmed from the popular belief that senior members of congress tend to promote personal interests or are more influenced by lobbying efforts that may not be representative of their constituents today term limits continue to be discussed but have not been enacted instead many members have focused their energies toward minimizing the time spent on any particular committee of congress believing that tenure on a committee is a more serious concern than simple tenure in congress implicit in these concerns is the issue whether as incumbent politicians plan to retire they will behave differently and if so whether tenure on a congressional committee exacerbates this behavior this article explores the role of membership on the appropriations committee on the distribution of federal research funding to universities specifically it explores whether funding is diverted to these universities because politicians use their position on a committee to promote personal or constituent interests previous research on shirking compares the voting records of politicians on certain issues with demographic and economic characteristics of the politicians constituents this article explores the issue of shirking differently i explore how membership on congressional appropriations committees affects the distribution of federal research funding to universities i look at two types of relationships between the members and the universities first i consider the relationship between members and the universities that are located in the members districts states in the case of senators second i examine the relationship between members and their undergraduate alma mater i use district representa tion to proxy favoritism that reflects a politician s constituents given that in most instances an alma mater affiliation is not the same as district representation i use alma mater affiliation to proxy favoritism that reflects the politician s personal interests federal research funding accounts for more than 60 of research funding received by research universities previous research has shown a positive impact of federal funding on research outcomes see adams and griliches 1998 arora and gambardella 1997 connolly 1997 payne and siow 2002 and payne 2001 except for payne and siow 2002 however these articles do not consider that political diversion of funds may promote or detract from research productivity as with any other federal program this article concentrates on the impact of membership on the house and senate appropriations committees because they wield the greatest power in the allocation of funding 1 using a panel data set spanning 26 years i explore how changes in the composition of the appropriations committees affects the distribution of research funding after controlling for the heterogeneity that exists across different universities the results suggest that both district representation and alma mater affiliation matter thus there is evidence of shirking for personal interests and evidence of members representing their constituents with respect to the representation of one s constituents the strongest results suggest that public universities benefit from representation on both the senate and house committees private universities however only benefit from representation in the senate with respect to alma mater affiliations the results suggest again that public universities benefit from representation on both the senate and house committees private universities also benefit from representation on both the senate and house committees the results also suggest that the tenure of the member on the committee matters as does whether the member is a part of the majority party in power in the congressional chamber

barriers to competition and the effect on political shirking 1953 1992 economists and political scientists have offered a variety of explanations for why legislators might rationally choose to ignore the preferences of their constituents political parties and presidents the broad conclusion of this literature is that there is an element of shirking in congressional voting the objective of this paper is to suggest that the effects of shirking in congressional voting may have increased over time largely in response to the raising of barriers to competition in congressional elections thereby enabling legislators to vote their own preferences without fear of losing reelection we use a quasi experimental design that controls for the effects of party region electoral safety presidential control of the white house and constituency factors in isolating the causal effects of barriers to entry on a continuous series of roll calls regarding the raising of the debt limit between 1953 and 1992 we find that shirking in legislative voting on debt limit legislation is a post 1970s phenomenon

the effects of changes in capital gains taxes on land sales empirical evidence from finland we estimate the landowner response to and fiscal effects of a temporary reduction in capital gains taxes imposed on land sales the underlying normative decision rules are first derived and solved numerically using stochastic dynamic programming the landowner preferences and willingness to sell land are then estimated in the reduced form using survey data from finland the results suggest that the timing of land sales and land sales quantities respond significantly to tax incentives certain temporary tax waiver programs could maintain the current tax revenues with fewer trade distorting effects on the land market

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

the truth the whole truth and nothing but the truth a multiple country test of an oath script hypothetical bias is one of the main issues bedeviling the field of nonmarket valuation the general criticism is that survey responses reflect how people would like to behave rather than how they actually behave in our study of climate change and carbon emissions reductions based on the increasing bulk of evidence from psychology and economics regarding the effects of making promises we investigate the effect of an oath script in a contingent valuation survey the survey was conducted in sweden and china and its results indicate that an oath script has significant effects on respondent behavior in answering willingness to pay wtp questions in both countries the shares of zero wtp responses and extremely high wtp responses decrease when an oath script is used resulting in lower variance furthermore the conditional wtp decreases in the chinese but not in the swedish sample we also find that the effect of the oath script is not generally dependent on respondent characteristics and the few differences we observe vary with the countries

a natural experiment approach to contingent valuation of private and public uv health risk reduction strategies in low and high risk countries we present the results of a natural experiment to test how variations in exogenous risk levels affect resultant willingness to pay wtp for risk reduction the case study presented considers wtp for reductions in the skin cancer risks associated with exposure to solar uv radiation a common design contingent valuation survey is conducted in four countries across which variation in geographical latitude and genetic mix mean that exogenous risks differ substantially survey respondents were presented with both a private and public good route for affecting risk reduction in both cases results confirm that once adjustment had been made for expected relationships with other covariates such as income and risk averting behaviour valuation responses for both goods conformed to expectations with the ordering of values across countries reflecting the ordering of scientifically established health risks this suggests that links between values and objective health risks may be observed within such situations and provides a justification for continuing research into more natural representations of risk and risk reductions in order to yield consistent and robust measures of associated values

are we willing to pay enough to back the bid valuing the intangible impacts of london s bid to host the 2012 summer olympic games using a contingent valuation survey this paper provides the first empirical test of the proposition that intangible impacts might justify hosting major sporting events on cost benefit grounds respondents drawn from london manchester and glasgow were asked for their willingness to pay wtp to host the 2012 olympic games in london on the basis of the intangible impacts that this event might provide annual mean wtp is 22 12 and 11 per year for 10 years in these 3 uk cities respectively an illustrative total uk wtp for intangible impacts is in the region of 2 billion statistical analysis of wtp determinants reveals a range of plausible explanatory factors such as respondents degree of support for the bid

an incentive compatible conjoint ranking mechanism a simple method for making ranking based conjoint analysis incentive compatible is proposed the incentive compatible mechanism involves people purchasing a product profile with a probability proportional to its assigned rank in an empirical application related to consumer preferences for beef attributes we find that the forecasted market share for a new pasture raised steak obtained using incentive compatible rankings was significantly greater than that implied from traditional hypothetical conjoint rankings people s rankings of ground beef products were not affected by the mechanism or by information about pasture raised beef copyright 2008 oxford university press

common agricultural policy effects on dynamic labour use in agriculture abstract the aim of this study is to investigate the effects of direct payments and rural development measures of the eu s common agricultural policy cap on employment in agriculture we work with a dynamic labour demand equation augmented by the full set of policy instruments of the cap which is estimated on a panel dataset of 69 east german regions we present results for four estimators which differ in how they eliminate the fixed effects and how they address the endogeneity of the lagged dependent variable the results suggest that there were few desirable effects on job maintenance in agriculture while there is some indication that investment subsidies have halted labour shedding on farms a rise in the general wage level reduced labour use in agriculture changes in direct payments had no employment effects generally labour adjustment exhibits a strong path dependency

economic evaluation of environmental externalities in china s coal fired power generation abstract serious environmental externalities exist in china s power industry environmental economics theory suggests that the evaluation of environmental externality is the basis of designing an efficient regulation the purposes of this study are 1 to identify chinese respondents preferences for green development of electric power industry and the socio economic characteristics behind them 2 to investigate the different attitudes of the respondents towards pollution and co2 reduction 3 to quantitatively evaluate the environmental cost of china s coal fired power generation based on the method of choice experiments ce and the 411 questionnaires with 2466 data points we found that chinese respondents prefer pm2 5 so2 and nox reduction to co2 reduction and that the environment cost of coal fired power plants in china is 0 30 yuan per kwh in addition we found that the socio economic characteristics of income education gender and environmental awareness have significant impacts on respondents choices these findings indicate that the environmental cost of coal fired power generation is a significant factor that requires great consideration in the formulation of electric power development policies in addition importance should also be attached to the implementation of green power price policy and enhancement of environmental protection awareness

mitigating hypothetical bias in stated preference data evidence from sports tourism one of the major criticisms of stated preference data is hypothetical bias using a unique dataset of both stated and actual behavior we test for hypothetical bias of stated preference survey responses we consider whether respondents tend to overstate their participatory sporting event behavior ex ante when compared to their actual behavior at different registration fees we find that stated behavior accurately predicts actual behavior at a middle level of respondent certainty overpredicts actual behavior at a lower level of certainty and underpredicts behavior at a higher level of certainty this result suggests that respondent uncertainty corrections can be used to mitigate hypothetical bias and stated preference data can be used to better understand actual behavior in situations where no data exist jel l83 q51 z2

in search of homo economicus behavioral experiments in 15 small scale societies we can summarize our results as follows first the canonical model is not supported in any society studied second there is considerably more behavioral variability across groups than had been found in previous cross cultural research and the canonical model fails in a wider variety of ways than in previous experiments third group level differences in economic organization and the degree of market integration explain a substantial portion of the behavioral variation across societies the higher the degree of market integration and the higher the payoffs to cooperation the greater the level of cooperation in experimental games fourth individual level economic and demographic variables do not explain behavior either within or across groups fifth behavior in the experiments is generally consistent with economic patterns of everyday life in these societies

jobs and agricultural policy impact of the common agricultural policy on eu agricultural employment abstract this paper investigates the relationship between eu agricultural subsidies and the outflow of labor from agriculture we use more representative subsidy indicators and a wider coverage panel data from 210 eu regions over the period 2004 2014 than has been used before the data allow to better correct for sample selection bias than previous empirical studies we find that on average cap subsidies reduce the outflow of labor from agriculture but the effect is almost entirely due to decoupled pillar i payments coupled pillar i payments have no impact on reducing labor outflow from agriculture i e on preserving jobs in agriculture the impact of pillar ii is mixed our estimates predict that an increase of 10 percent of the cap budget would prevent an extra 16 000 people from leaving the eu agriculture sector each year a 10 percent decoupling would save 13 000 agricultural jobs each year however the budgetary costs are large the estimated cost is more than 300 000 per year or more than 25 000 per month per job saved in agriculture

rural population decline in the 1980s impacts of farm structure and federal farm programs federal farm program benefits accrue disproportionately to large scale farm operators and continue largely because of the political influence of their beneficiaries some writers argue that these payments stem the movement of labor out of agriculture ultimately reducing the pace of rural depopulation here a theoretical model linking farm program payments to population loss is presented and empirically estimated for the years 1980 90 larger farm program payments as a share of total cash marketing receipts were associated with greater population losses from rural counties this result holds after controlling for other economic variables affecting population migration from rural areas

contingent valuation a new perspective after several decades of academic research on the contingent valuation cv method a consistent behavioral explanation of hypothetical bias is still lacking based on evidence from economics economic psychology and the political sciences i propose an explanation that is based on two simple working hypotheses about respondent behaviour in contingent valuation surveys the first hypothesis is that survey respondents are unable to form consistent preferences about unfamiliar goods unless the choice context offers reliable informative cues that can be rationally exploited in simplified heuristics the second hypothesis is that the probability and impact of strategic responses in dichotomous choice questions about public goods depends on the extent to which the presented hypothetical costs differ from the actual costs the literature on hypothetical bias is revisited in the light of these behavioral hypotheses i find that the hypotheses are generally supported by the empirical data moreover the hypotheses are able to explain several important empirical phenomena that previous research has not been able to explain in particular they solve the puzzle that pre election polls but not cv surveys are able to predict actual referendum outcomes and they explain why income effects on willingness to pay are lower in cv responses than in actual votes if confirmed by further studies the hypotheses will have important implications for future research and practice first the hypothetical costs presented in the dichotomous choice question should to be close enough to the actual costs to be credible to all respondents this can be achieved by specifying the costs as a percentage rather than absolute change in taxes second the respondents should be given the option to answer based on information about the positions of large parties and interest groups with known political orientation rather than based on the raw policy information theory and evidence suggest that this new survey paradigm largely eliminates the fundamental problems of the conventional stated preference methods

measuring the environmental cost of hypocrisy this paper provides an example of how to estimate the marginal environmental cost of hypocrisy using revealed behavior and self identification survey responses from coffee drinkers regarding their use of cardboard and plastic i e non reusable cups coffee shops provide a convenient microcosm for assessing the impact of hypocritical behavior because of 1 readily available cheap substitutes i e reusable coffee cups 2 a relatively accurate estimate of the environmental in particular carbon cost associated with using non reusable cups and 3 the ability to delineate hypocritical behavior by observing a choice with relatively few potential confounding factors hypocritical behavior is measured as a geometric mean of how often an individual takes coffee in a non reusable cup and the degree to which the individual self identifies as being concerned about his environmental footprint all else equal the more often a person takes his coffee in a non reusable cup and the greater the degree to which he self identifies as being concerned about his footprint the greater the individual s hypocrisy score controlling for other attitudinal and demographic characteristics including self identified awareness of environmental issues and willingness to pay for the convenience of using a non reusable cup we are able to determine the marginal effect of an individual s hypocrisy score on the environmental cost associated with the use of non reusable coffee cups

dynamic estimation of ideal points for the us congress theories of candidate positioning suggest that candidates will respond dynamically to their electoral environment because of the difficulty of obtaining bridge votes most existing approaches for estimating the ideal points of members of congress generate static ideal points or ideal points that move linearly over time we propose an approach for dynamic ideal point estimation using project vote smart s national political awareness test to construct bridge votes we use our dynamic estimates to measure aggregate change to measure individual level change and to study the institutional and structural factors that explain the changing positions of house candidates and members of congress we demonstrate that while the republican party has been selecting increasingly extreme candidates democratic incumbents have become more extreme while in office we also find that the congruence between elected members of congress and their constituents is mostly explained by the selection as opposed to the responsiveness of the candidate nonetheless we find evidence of dynamic responsiveness of incumbents in specific circumstances we find that competitiveness midterm elections and sharing the president s party affiliation are associated with greater responsiveness conversely retirement is not associated with a change in responsiveness we find no evidence of responsiveness of challengers finally we find that close elections draw challengers who are more in line with the district s ideology

benefits transfer of willingness to pay estimates and functions for health risk reductions a cross country study this paper provides a first application of the techniques of benefits transfer to the health economics literature these techniques seek to transfer the value of some good from one survey context to a new policy context so avoiding the need for new valuation surveys each time a new policy question arises two approaches to benefits transfer are assessed the simple transfer of mean values and the transferral of value functions we develop a new methodology for the latter approach in which value functions are iteratively built up from theoretical principles with transfer errors being tested each time a new variable is added through a novel application of advanced statistical tests we show that this approach outperforms the transferral of statistically driven best fit functions the case study presented focuses upon the transfer of contingent valuation cv willingness to pay wtp estimates and associated value functions for reducing the health risks associated with solar ultraviolet uv exposure common format studies are conducted in four countries with transfers between all of these being undertaken by calculating errors in predicted versus actual values across countries we show that when transferring between similar contexts simple mean value transfers outperform more complex value function transfers with the magnitude of the former errors being encouragingly small however this result is reversed when transfers are undertaken across dissimilar contexts where value functions partially adjust for these differences in summary these findings provide support and guidance for future applications

neoclassical theory versus prospect theory evidence from the marketplace several experimental studies have provided evidence that suggest indifference curves have a kink around the current endowment level these results which clearly contradict closely held economic doctrines have led some influential commentators to call for an entirely new economic paradigm to displace conventional neoclassical theory e g prospect theory which invokes psychological effects this paper pits neoclassical theory against prospect theory by investigating data drawn from more than 375 subjects actively participating in a well functioning marketplace the pattern of results suggests that prospect theory adequately organizes behavior among inexperienced consumers but consumers with intense market experience behave largely in accordance with neoclassical predictions moreover the data are consistent with the notion that consumers learn to overcome the endowment effect in situations beyond specific problems they have previously encountered this transference of behavior across domains has important implications in both a positive and normative sense

convergent validity of attribute based choice questions in stated preference studies the application of attribute based choice questions is well established in the marketing literature but there are unique aspects of the design that warrant investigation to assess their validity for economic welfare estimation three design issues are investigated in this paper 1 the placement of the monetary stimulus policy cost to respondents in the sequence of attributes 2 the number of policy alternatives respondents are asked to consider in choice questions two versus three and 3 the inclusion versus exclusion of a status quo alternative in choice questions the data used to implement these investigations are from a survey designed to estimate the value maine residents place on a farmland conservation easement program tests of convergent validity indicate that the placement of the monetary stimulus first versus last in the list of attributes did not affect estimates of preference parameters significant differences between questions with three versus two alternatives did occur and the inclusion exclusion of a status quo alternative did not affect preference parameters

are valuations from nonhypothetical choice experiments different from those of experimental auctions due to the importance of comparability and external validity of results nonhypothetical experimental methods are increasingly used to elicit consumers willingness to pay for various goods two of the increasingly popular preference elicitation methods are the nonhypothetical choice experiments and experimental auctions we conduct experiments to compare willingness to pay estimates elicited from both methods our results generally suggest that valuations elicited from experimental auctions can differ from those obtained from nonhypothetical choice experiments copyright 2011 oxford university press

input subsidies cash constraints and timing of input supply is low input use by poor smallholder farmers caused by time inconsistent behavior or by limited ability to buy inputs are input subsidies the best solution to stimulate input demand or are there smarter solutions these issues are investigated by combining survey data stated preference questions and randomized experiments in malawi the demand for fertilizer at harvest time and at planting time farm gate shadow prices for fertilizer and the gap between the willingness to accept wta and willingness to pay wtp prices for a standard input package were investigated significant effects of timing and of cash constraints were found suggesting the possibility that smarter designs exist such as distribution of smaller packages from harvest time to planting time

revealed and stated preferences for co2 emissions reduction the missing link abstract in this paper we combine data collected from two strands of literature dealing with revealed preferences expressed by conventional vehicle drivers for fuel price variation and stated preferences expressed by consumers for alternative fuel vehicles we employ a meta analysis approach drawing data on 30 primary studies reflecting two important policy interventions which are fuel price taxation and subsidies for alternative fuel vehicles this is a new contribution in environmental and energy economics in that we rescale all primary information into a unique index which captures consumers economic attitude towards carbon dioxide co2 emission reduction in monetary terms focusing on the transport sector we compute the implicit price for the avoidance of a kilogram of co2 emissions named pco2 explaining the existing heterogeneity from several points of view the results of the meta analysis show that contextual and individual characteristics influence the implicit price for co2 emissions avoidance this implicit price is on average positive in the case of revealed preferences studies whereas it is negative in the stated preferences studies although there are some important geographical differences our results show that fuel taxes could be an important additional instrument for environmental policy

can consumers willingness to pay incentivize adoption of environmental impact reducing technologies in meat animal production abstract this study develops a model estimating consumer willingness to pay wtp for environmental meat attributes and uses a multi objective nutritional optimizer to explore the extent to which wtp can offset on farm costs of reducing water use data for the wtp model are sourced from a literature survey of the agricola and google scholar databases yielding 46 studies estimating wtp for pure and impure organic grass fed natural environmental meat attributes bayesian analysis is used to estimate 3 models varying in independent variables models are evaluated by the correlation coefficient r2 root mean squared error of prediction rmspe and posterior model probability the most probable model is then used to estimate a confidence range of wtp for pure environmental beef impure environmental labels result in higher wtp than pure labels non hypothetical wtp for pure environmental labeling for north american consumers ranges from 6 7 to 32 6 a case study is conducted to identify the expected reduction in water use that can be funded from capturing wtp through labeling a multi objective nutritional optimizer is used to identify ideal management of beef cattle to reduce whole system water use in three regions of the united states cost increases from management are varied over the predicted range in wtp and combined with the probability of a consumer purchasing beef at each wtp value to identify the theoretical effect on expected environmental impact reduction a 10 premium is the ideal wtp resulting in water use reductions between 24 4 l and 41 4 l

bridging the gap between revealed and stated preferences in flood prone housing markets abstract this papers attempts to shed light on the gap between revealed and stated preferences methods in flood prone housing markets we quantitatively explore the market level consequences of various behavioural models assumptions regarding risky choices at the individual level in addition we quantify the effect of the market level bias in risk valuation that individual preferences for neighbourhood quality imply we apply an economic agent based housing market model to quantify and disentangle the impacts of behavioural biases in individual decisions under risk as well as neighbourhood externalities which both are known to distort markets we compare three different micro level behavioural risk models expected utility prospect theory and risk negligence the flood risk discount on a market level varies significantly but the results do not rule out any of these models in general markets with prospect theory traders overprice risks causing an unrealistically high price differential between risk prone and risk free properties the marginal implicit price for flood risk is much closer to empirically found prices in the expected utility and risk negligence models additionally we find that individual preferences for neighbourhood quality and multicollinearity in housing attributes can cause a bias in market level risk valuations of up to 9 7 of a property s value

on the intersectoral migration of agricultural labor labor is the single most important factor in determining national income as economies grow agricultural labor declines as a share of total labor and converges to a level of 2 or 3 percent off farm migration facilitates the development of nonagriculture but historically the process spans decades the authors argue that the pace of the process is a fundamental outcome of a dynamic equilibrium based on expectations of lifetime earnings and the cost of migration the authors present an empirical model of the determinants of intersectoral migration one fundamental determinant is income differences across sectors as such migration should stop when income differences reach a certain level the authors provide a method of measuring the level at which intersectoral migration will cease while there are credible reasons for a permanent difference to exist between sectoral incomes the authors find no empirical evidence of a permanent wedge

legislator voting and shirking a critical review of the literature we set out to critically review the progress in answering two related questions what determines how legislators vote and how can shirking by legislators be measured in the first category the hypothesis that legislators shirk in order to indulge their personal ideological preferences has led researchers astray the theoretical underpinning is shaky on two counts first legislators who indulge their preferences at the expense of their constituents preferences put themselves at a competitive electoral disadvantage second the original two stage procedure used to measure ideological shirking is severely flawed among many other problems the residual measure of shirking implicitly assumes that the median voter is the relevant constituent principal for the legislator agent

transition and agricultural labor reforms have strongly affected agricultural employment in transition countries but in remarkably different ways we present a theoretical model and an empirical analysis to explain differences in labor adjustment during transition we show that the differences are due to a combination of variations in initial conditions and differences in reform policies and effects the removal of price distortions and subsidies caused wage and price adjustments during transition and a reduction in labor demand in agriculture surplus labor outflow from agriculture was further stimulated by the privatization of the farm assets as they improve incentives and remove constraints for optimal factor allocation and structural adjustment the shift to individual farms which was especially strong in labor intensive production systems with low labor productivity in agriculture has reduced the outflow of labor from agriculture by improving farm governance and labor efficiency although this effect was mitigated by losses in scale economies due to disruptions and market imperfections in transition in general labor outflow was considerably lower on individual farms than on corporate farms due to a combination of factors related to human capital access to finance and physical capital in the last section of the article we present a general framework for understanding labor adjustments in transition countries specifically we show that there are several patterns of labor transition in one pattern followed by e g the czech republic and hungary there is initially a strong survival of the restructured large scale corporate farms that have laid off many workers in the second phase of transition gradually the importance of individual farms increases in other countries such as romania the opposite has happened in these countries there is an immediate strong shift to individual farms while labor use increases on average in agriculture after this initial phase the shift to individual farms continues albeit more slowly and labor use in agriculture starts to decline finally our analysis shows that in countries such as russia and ukraine much of the surplus labor is still employed by little reformed former collective and state farms major adjustments await more progress in agricultural and general reforms

stated versus revealed knowledge determinants of offsetting co2 emissions from fuel consumption in vehicle use abstract this paper examines the role of prior knowledge in offsetting co2 emissions from fuel consumption in vehicle use the main result of our econometric analysis on the basis of unique representative data from drivers license holders in the usa and germany refers to the strong discrepancy between the stated and revealed knowledge of co2 offsetting the revealed knowledge measured by the correct estimation of the costs for this offsetting practice has a positive impact on the stated purchase of corresponding offsetting credits in both countries in contrast the effect of the stated knowledge of offsetting is not robust and in some cases even negative surprisingly it cannot even be confirmed that drivers license holders who claim that they are more than sufficiently informed estimate these costs more accurately

growth of milk production in german dairy farms an empirical study based on event history analysis this article investigates determinants of growth of milk production in german dairy farms with the use of event history analysis this methodology enables the analysts to consider time as a proxy for not measurable effects on growth the likelihood of a farm s moving from a nongrowth episode into a growth episode is estimated and the impact of various covariates on that likelihood is assessed the analysis is based upon a balanced panel of annual farm accounts from 616 specialized dairy farms in germany covering the financial years 1995 1996 2008 2009 the results from event history analyses are presented for low and high growth rates for both groups it was found that the probability of entering a growth episode defined as the event to be analyzed increases over time e g as a consequence of an increasing need to improve competitiveness moreover several covariates such as the share of subsidies in returns farmer s age and milk price had a significant impact on growth in a farm s milk production the analysis revealed however that the effect direction of some explanatory variables differed between the two groups

land market imperfections and agricultural policy impacts in the new eu member states a partial equilibrium analysis this article analyses how transaction costs and imperfect competition in the land market affect the welfare effects of agricultural subsidies in the new eastern member states of the european union benefits of land subsidies end up with landowners in new eastern member states also with imperfections in the new eastern member states land markets with unequal access to subsidies small tenant farmers may even lose out from the subsidies decoupling of payments shifts policy rents to farmers but constrains productivity enhancing restructuring using reserve entitlements to mitigate this effect reduces the intended benefits on distortions and target efficiency

term limitation in a dynamic model of partisan balance in november 1992 voters in fourteen states considered ballot propositions to adopt term limits for members of congress all fourteen propositions passed ten received more than 60 support bringing the total number of states with congressional term limits to fifteen much of the discussion of term limitation has focused on issues of representation the strength of parties and the functioning of congress after the adoption of limits benjamin and malbin 1992 will 1992 this paper explores an important but less discussed consequence of term limitation its impact on the partisan balance of legislatures we inquire how electoral dynamics incumbent advantage and voluntary retirement interact with a term limit to produce a new balance between parties in a two party legislature which party is favored by the introduction of term limits how does the length of the term limit matter are there conditions such that one party will be favored by any limit regardless of how restrictive

international benefit transfer methods and validity tests abstract the use of value estimates measured in one country to value policy changes in another country would seem to introduce some unique issues and challenges even when the good being valued is identical these issues include how should values be converted from one currency to another how to account for differences in measurable characteristics when those can vary markedly between countries especially income and how to account for differences between countries in culture and shared experiences that are difficult to quantify however these challenges in international benefit transfer are not that different from those encountered in transfers between regions within a country and transfer errors are comparable to those seen in intra country transfers

convergent validity of revealed and stated recreation behavior with quality change a comparison of multiple and single site demands we consider the convergent validity of several demand models using beach recreation data two models employ multiple site data a count data demand system model and the kuhn tucker demand system model we explore the role of existing variation in beach width in explaining trip choices and analyze a hypothetical 100 foot increase in beach width we compare these models to a single equation model where we jointly estimate revealed and stated preference trip data and focus on a hypothetical scenario considering a 100 foot increase in beach width in each case we develop estimates of the change in beach visits and the welfare impacts from the increase in width the trip change estimates from two of the three models are similar and convergent valid though the willingness to pay estimates differ in magnitude

using neuroeconomics to understand environmental valuation contingent valuation choice experiments and other stated preference methods are frequently used to capture the nonmarket valuation of natural resources and ecosystem services the emerging field of neuroeconomics which assesses the neuroscience underlying decision making plots a promising course to explore the mechanisms underlying complex environmental valuation decisions neuroeconomic methods offer a unique capacity to isolate value components that contribute to willingness to pay wtp separating an individual s response to natural resource attributes that are of interest to economists from other attributes or influences on the decision process neuroimaging data can also aid in understanding differences in response between preference elicitation techniques and identifying the use of different decision processes and heuristics during valuation this article surveys the benefits and limitations of using neuroeconomics methods to assess the value of environmental goods and focuses on three examples where neuroeconomics may inform environmental valuation protest responses comparison of hypothetical and consequential choice contexts and the evaluation of environmental attributes and optimization of study design in stated choice experiments neuroeconomics methods offer a foundation for positive collaboration between environmental economists and cognitive neuroscientists yielding metrics that complement and augment current stated preference methods of determining environmental valuation

evaluating the validity of the dichotomous choice question format in contingent valuation hypothetical and actual cash willingness to pay wtp for an art print were elicited with dichotomous choice and open ended question formats comparing hypothetical and actual dichotomous choice responses using both a likelihood ratio test and the method of convolutions suggests we reject equality at the 0 05 but not the 0 01 level hypothetical wtp was roughly two times actual wtp with the dichotomous choice format there were no significant differences between the open ended and dichotomous choice question formats when both were used to estimate hypothetical wtp or both used to estimate actual wtp

the importance of taste in experimental auctions consumers valuation of calorie and sweetener labeling of soft drinks a majority of purchases that consumers make are classified as repeat purchases one of the main reasons why consumers make repeat food purchases is the food s taste therefore we examined the importance of including taste testing in nonhypothetical experimental auctions specifically we used two experiments to determine consumers willingness to pay for soft drinks labeled with different calorie and sweetener information in experiment 1 participants tasted the soft drinks prior to the bidding rounds in experiment 2 participants did not taste the soft drinks prior to the bidding rounds bidding behavior for the soft drinks was significantly different between experiment 1 and experiment 2 results suggest that including taste testing in the design of experimental auctions is important to accurately capture consumers willingness to pay for foods that are purchased repeatedly results also imply that policies aimed at combating obesity by making the calorie content of foods more visible may not produce desired outcomes

benefit transfer in europe how reliable are transfers between countries the benefits for specific health impacts related to air and water quality were measured in simultaneous contingent valuation surveys conducted in five different european countries consistent inter country differences in willingness to pay to avoid ill health episodes could not be explained by measurable differences in individual characteristics international transfer of unit values resulted in an average transfer error of 38 accounting for measurable differences among countries in health status income and other demographic measures either through ad hoc adjustments to the transferred values or through value function transfer did not improve transfer performance

preference elicitation under oath eliciting sincere preferences for non market goods remain a challenge due to the discrepency between hypothetical and real behavior and false zeros the gap arises because people either overstate hypothetical values or understate real commitments or a combination of both herein we examine whether the traditional real world institution of the solemn oath can improve preference elicitation applying the social psychology theory on the oath as a truth telling commitment device we ask our bidders to swear on their honour to give honest answers prior to participating in an incentive compatible second price auction the oath is an ancillary mechanism to commit bidders to bid sincerely in a second price auction results from our induced valuation testbed treatments suggest that the oath only auctions outperform all our other auctions real and hypothetical in our homegrown valuation treatments eliciting preferences for dolphin protection the oath only design induced people to treat as binding both their experimental budget constraint i e lower values on the high end of the value distribution and participation constraint i e positive values in place of the zero bids used to opt out of auction based on companion treatments we show the oath works through an increase in the willingness to tell the truth due to a strengthening of the intrinsic motivation to do so

the deadweight loss of christmas when economists comment on holiday gift giving it is usually to condone the healthy effect of spending on the macroeconomy however an important feature of gift giving is that consumption choices are made by someone other than the final consumer a potentially important microeconomic aspect of gift giving is that gifts may be mismatched with the recipients preferences in the standard microeconomic framework of consumer choice the best a gift giver can do with say 10 is to duplicate the choice that the recipient would have made while it is possible for a giver to choose a gift which the recipient ultimately values above its price for example if the recipient is not perfectly informed it is more likely that the gift will leave the recipient worse off than if she had made her own consumption choice with an equal amount of cash in short gift giving is a potential source of deadweight loss this paper gives estimates of the deadweight loss of holiday gift giving based on surveys given to yale undergraduates i find that holiday gift giving destroys between 10 percent and a third of the value of gifts while these recipients may be unrepresentative of the u s population their gifts are not necessarily unrepresentative holiday expenditures average 40 billion per year implying that a conservative estimate of the deadweight loss of christmas is a tenth as large as estimates of the deadweight loss of income taxation i also explore how deadweight loss and the tendency to give cash gifts vary with the relationship and age difference between giver and recipient i find that gifts from friends and significant others are most efficient while noncash gifts from members of the extended family are least efficient and destroy a third of their value i develop a simple expected utility model to explain the decision to give cash as opposed to in kind gifts the data are consistent with the model cash gifts are most common from the sorts of givers whose noncash gifts have the lowest expected value to recipients given their cost and high variability in recipient valuation

the determinants of the migration of labor out of agriculture in the united states 1940 85 the flow of labor out of production agriculture is analyzed using a two sector model of occupational choice a migration equation is specified and tested empirically using aggregate data for the united states the economic determinants of the migration of all farm workers and farm operators are established farm labor is found to be responsive to changes in the returns to agricultural labor relative to nonfarm labor returns given this responsiveness policies intended to increase farm income will affect the level of agricultural employment

credit market imperfections and the distribution of policy rents this article shows that credit market imperfections have important implications for the distribution of policy rents in a model with land as fixed factor and credit market imperfections when an area payment is given land rents go up by more than the subsidy on aggregate farms may lose from the subsidy the results depend on the extent to which subsidies have direct and indirect effects on the credit constraints on whether farms rent or own land and on farm heterogeneity

dynamic hypothetical bias in discrete choice experiments evidence from measuring the impact of corporate social responsibility on consumers demand abstract this paper is aimed at studying the dynamics of consumers preferences for corporate social responsibility the data come from both a discrete choice experiment dce and a field experiment conducted in a real market setting the results show that in a static setting first month predictions of a standard dce study and real market shares are statistically similar for the various profiles of corporate social responsibility however as time evolves real market shares present some dynamic patterns that are not mirrored by the standard dce predictions the overall conclusion is that differences between real market behavior and dce data can be attributed to the lack of learning experience or adaptation in dce surveys rather than to the hypothetical nature of the experiments

promoting structural adjustment in agriculture the economics of new entrant schemes for farmers we examine the efficacy of incentives for new entrants to farming as an alternative to early retirement schemes for farmers we briefly review previous studies on the effectiveness of farmer early retirement schemes in promoting structural adjustment in agriculture and conclude that the economic case for these schemes seems weak we then employ a dynamic farm optimisation model incorporating a realistic specification of farmer decision making on an original northern irish dataset to analyse ex ante the possible impacts of new entrant schemes we find a more positive potential impact from these schemes particularly the option of an interest rate subsidy on farm development loans this is attributed to the dynamic effects of the farm investments associated with such schemes a likely reflection of the long term effects of differences in age related lifecycle goals younger farmers have a longer planning horizon and tend to invest more heavily in business growth than comparable older age groups

are politicians really paid like bureaucrats abstract we provide the first empirical analysis of gubernatorial pay using u s data for 1950 90 we document substantial variation in the wages of politicians both across states and over time gubernatorial wages respond to changes in state income per capita and taxes we estimate that governors receive a 1 percent pay cut for each 10 percent increase in per capita tax payments and a 4 5 percent increase in pay for each 10 percent increase in income per capita in their states there is evidence that the tax elasticity reflects a form of reward for performance the evidence for the income elasticity of pay is less conclusive but is suggestive of rent extraction motives finally we find that democratic institutions play an important role in shaping pay for example voter initiatives and the presence of political opposition significantly reduce the income elasticity of pay and increase tax elasticities of pay
