dynamic interaction between markets for leasing and selling automobiles we develop a model of dynamic interactions between price variations in leasing and selling markets for automobiles our framework assumes a differential game between multiple bertrand type competing firms which offer differentiated products to forward looking agents empirical analysis of our model using monthly us data from 2002 to 2011 shows that variations in selling cash market prices lead rapidly dissipating changes of leasing market prices in the opposite direction we discuss the practical implications of these results by augmenting a standard leasing valuation formula the additional terms represent the leased asset value changes that can be expected on the basis of past variations in automobile selling market prices

joint estimation of multiple cvm scenarios under a double bounded questioning format contingent valuation surveys frequently ask the same respondent for willingness to pay wtp for either different programs or different levels of provision of a single program when multiple scenarios are considered by the respondent the errors in the estimates of wtp are likely to be correlated across scenarios failing to account for correlation may lead to erroneous inferences concerning differences in wtp this paper presents a technique that can be used to jointly estimate wtp for multiple scenarios proposed within a survey when the double bounded questioning format is used monte carlo simulations are employed to show that estimates derived from the joint model provide lower parameter variances as well as tighter confidence intervals surrounding wtp the model is used to estimate wtp values for data collected in telephone interviews of california residents concerning wtp for fire reduction programs in oregon and california variance properties of these estimates are shown to be similar to those estimated using simulated data

fixed costs and long lived investments abstract fixed costs models are difficult to analyze because they feature non degenerate time varying distributions of capital across firms if investments are sufficiently long lived however then the cross sectional distribution of capital holdings has virtually no bearing on the equilibrium and the aggregate behavior of fixed cost models is essentially identical to neoclassical models the findings are due to a near infinite elasticity of investment timing for long lived investments a feature shared by fixed cost models and neoclassical models irrelevance results found in numerical studies of fixed cost models are not parametric special cases but instead are fundamental properties of models with long lived investment goods

identifying the warm glow effect in contingent valuation abstract this paper reports the results from a contingent valuation study designed to investigate the influence of warm glow in willingness to pay wtp responses interindividual differences in warm glow motivation are measured through a factor analysis performed on a list of attitudinal items the reported wtp measures fail to pass the scope test both socioeconomic variables and motivational factor scores are significant in the explanation of the individual wtp measures we compute cold wtp measures by taking out the effect of the warm glow motivation these cold measures satisfy both the scope test and hausman s adding up property

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

stationary equilibrium in a market for durable assets this paper presents a dynamic model of consumer trading on the primary secondary and scrap markets for a stochastically deteriorating durable good in a stationary economy with perfect information and no transaction costs we explicitly model the trading process by tracking each durable from its birth in the primary market through its sequence of owners in the secondary market until its death in the scrap market we prove that a stationary equilibrium exists characterize the distribution of consumer holdings of durables and show that equilibrium asset prices are shadow prices to a particular regenerative optimal stopping problem we show that each heterogeneous agent equilibrium is observationally equivalent to a homogeneous agent equilibrium we derive a differential equation for equilibrium rental rates and a functional equation which links rental rates to asset prices these equations show precisely how the structure of durable prices and rental rates embody the functional form and population distribution of preferences and the technological characteristics of durable goods this abstract was borrowed from another version of this item

the role and growth of new car leasing theory and evidence abstractthere has been substantial growth in rates of new car leasing over the last few decades building on recent theoretical research we construct a model of the leasing decision in which leasing mitigates adverse selection and reduces transaction costs but moral hazard limits its use in our model the prevalence of leasing is related to new car reliability which suggests that the recent growth in leasing is at least partly due to improvements in new car reliability we use this model to derive testable implications and then conduct an empirical analysis to investigate whether the operation of the new and used car markets is consistent with the predictions of this theoretical approach our empirical results support the theoretical predictions of our model in particular we provide direct evidence that leasing mitigates adverse selection and that an important factor in the growth in new car leasing rates has indeed been the growth of new car reliability

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

differences between continuous and discrete contingent value estimates in a split sample contingent valuation study of willingness to pay wtp for food safety improvements the dichotomous choice dc elicitation method consistently generated much larger estimates of wtp than did a continuous method little or none of these differences was due to bias introduced by the statistical techniques used with the dc data most or all of the difference was due to differences in respondent behavior in addition the continuous wtp responses showed a significant scope effect while the dc responses did not the observed difference in behavior may be attributable in part to yea saying by dc respondents

existence of stationary equilibrium in the markets for new and used durable goods abstract we prove the existence of stationary equilibrium in the primary and secondhand markets for an indivisible consumer durable in a general model with stochastic degradation and endogenous scrappage decisions unlike rust econometrica 53 1985 783 we introduce transaction costs in the model as a motivation for consumer holdings of durables across multiple quality levels our technique allows for both multiple types of durables e g porsche and bmw and relaxation of the single crossing condition on consumer tastes we provide a simple example showing how increasing transaction costs affect secondhand prices eventually for sufficiently costly transactions closing the secondhand market altogether

a quantitative analysis of the used car market we quantitatively investigate the allocative and welfare effects of secondary markets for cars an important source of gains from trade in these markets is the heterogeneity in the willingness to pay for higher quality newer goods but transaction costs are an impediment to instantaneous trade calibration of the model successfully matches several aggregate features of the u s and french used car markets counterfactual analyses show that transaction costs have a large effect on volume of trade allocations and the primary market aggregate effects on consumer surplus and welfare are relatively small but the effect on lower valuation households can be large

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

revenue management for durable goods using trade ins with certified pre owned options abstract the economics research suggests that firms can use trade ins as a revenue management device for price discrimination between new and replacement buyers of durabprle goods offering different prices to different groups of customers creates a market segmentation effect this study examines such an effect by considering trade ins and certified pre owned options for a durable goods firm where certified pre owned cpo represents the used goods market generated from the return flow of trade in transactions the optimal pricing and or trade in rebate is determined and the strategic choice between the two options is examined an analytical model is developed that incorporates the key durable goods features into model formulation specifically the deterioration rate or durability in a reverse measure and the variation in quality of the used goods our research findings indicate that i the magnitude of trade in rebates increases with the deterioration rate and quality variation ii the segmentation effect outweighs the cannibalization effect when the deterioration rate is moderately high iii the strategic choice of trade ins and cpo options is critically dependent on these two features and iv the majority of profit improvement is generated from trade in provisions although the cpo option can serve as a second profit boosting device

valuation of natural resource improvements in the adirondacks for 20 years acid rain in the adirondack park has been a central issue in the debate about clean air regulation based on a contingent valuation survey of new york residents our study quantifies the total economic value of expected ecological improvements in the park from forthcoming policies our preferred estimates of the mean household willingness to pay range from 48 to 107 annually which imply total statewide benefits ranging from 336 million to 749 million annually alternative assumptions about ecological changes yield benefits up to 1 1 billion the instrument passes external scope sensitivity to bid and sample selection tests

resale and collusion in a dynamic market for semidurable goods the paper studies the incentives to form collusive agreements when goods can be traded in second hand markets it will be shown that such incentives crucially depend on the rate of depreciation of the durable good and on consumer heterogeneity the main contribution of the paper shows that an active second hand market may strengthen the incentives to collude as do policies that affect the functioning of the second hand market e g leasing policy and buy back it will also be argued that the oligopoly incentives to adopt strategies that strengthen collusion often differ from the monopoly incentives to increase profits

household willingness to pay for expanding fuel cell power generation in korea a view from co2 emissions reduction abstract the fuel cell fc is accepted as the state of the art instrument for reducing co2 emissions in the field of power generation in korea therefore the korean government has planned to expand fc power generation from 565 gwh in 2013 to 13 449 gwh by 2027 this article aims to assess the public value or acceptability of this expansion in terms of reducing co2 emissions to this end we derive the public s additional willingness to pay wtp for the expansion using a contingent valuation survey of 1000 korean households for the purpose of mitigating the response effect in eliciting their wtp and increasing statistical efficiency in analyzing the wtp data we employ a one and one half bounded dichotomous choice question format furthermore we use the spike model so as to model zero wtp responses the mean additional monthly wtp for the expansion is computed to be krw 1407 usd 1 37 per household expanding the value to the national population gives us krw 310 5 billion usd 304 4 million per year we can conclude that korean households are ready to shoulder some of the financial burden of expanding fc power generation to reduce co2 emissions

the learning curve market dominance and predatory pricing sufficient conditions for id and iid are given in the case of two step learning in which a firm reaches the bottom of its learning curve after just two sales however examples are also constructed for the two step learning case in which neither id nor iid holds it is also shown that in equilibrium iid implies that learning is privately disadvantageous although it is socially advantageous finally introducing avoidable fixed costs and possible exit into the model yields a new theory of predatory pricing based on the learning curve hypothesis

the validity of the contingent valuation method perfect and regular embedding this article deals with one aspect of the validity claim of the contingent valuation method namely to what extent does the method produce different values in situations for which economic theory claims different values two aspects of this validity test perfect and regular embedding were tested in a field experiment comprising six samples of the dutch population perfect embedding occurs when the value for a specific good is similar to the value for a more inclusive good perfect embedding did not manifest itself in the experiment respondents considered a package of six goods as well as a package of two goods more valuable than one of these goods it is argued that this supportive evidence of the method s validity claim occurred because the goods involved were well defined regular embedding occurs when the same good receives a lower value if the value for it is inferred from the value for a more inclusive good rather than if that good is valued on its own regular embedding was only found when respondents were given the opportunity to value the inclusive good before valuing the specific good respondents who were given information on the inclusive good without valuing it did not state different values than respondents who were not given that information it seems that respondents perceive an inclusive good as being relevant to their valuation decision only when they are asked to value it further research is necessary to shed more light on the underlying processes that may account for this

gasoline prices fuel economy and the energy paradox abstract policymakers often assert that consumers undervalue future gasoline costs when they buy automobiles we test this by measuring whether relative prices of vehicles with different fuel economy ratings fully adjust to variation in gasoline prices vehicle prices move as if consumers are indifferent between 1 00 in discounted future gas cost and 0 76 in vehicle purchase price we show how corrections for endogenous market shares and utilization measurement error and different gasoline price forecasts affect the results we also provide unique evidence of sticky information vehicle markets respond to changes in gasoline prices with up to a six month delay

understanding the role of trade ins in durable goods markets theory and evidence the act of trading in a used car as partial payment for a new car resonates with practically all consumers such transactions are prevalent in many other durable goods markets ranging from golf clubs to ct scanners what roles do trade ins play in these markets what motivates the seller to set up a channel to facilitate trade ins intuitively accepting a trade in would appear to stimulate demand for the producer s product but facilitating the resale of these used goods that substitute for new goods might also increase cannibalization although such transactions involve billions of dollars we know relatively little about this practice from the extant research literature this paper develops an analytical model that incorporates key features of real world durable goods markets i coexistence of new and used goods markets ii consumer heterogeneity with respect to quality sensitivity iii firms that anticipate the cannibalization problem arising from the coexistence of new and used goods and iv lemon problems in resale markets whereby sellers of used goods are better informed than buyers about the quality of their particular item in our analysis a trade in policy amounts to an intervention by the firm in the used goods market which reduces inefficiencies arising from the lemon problem it motivates owners to purchase new goods and reduces their proclivity to hold on to purchased goods because of the low price the latter would fetch in a lemon market we also show that trade in programs are more valuable for less reliable products as well as for products that deteriorate more slowly our analysis shows that producers in durable goods markets should consider trade in programs as a matter of routine despite cannibalization concerns arising from a more active resale market a producer s profits will inevitably rise from introducing trade ins given pervasive lemon problems we test the key predictions of the model about price and volume of trade by assembling a data set of transactions of u s automobile consumers and find broad support for our model

an empirical equilibrium model of a decentralized asset market i estimate a search and bargaining model of a decentralized market to quantify the effects of trading frictions on asset allocations and asset prices and to quantify the effects of intermediaries that facilitate trade using business aircraft data i find that relative to the walrasian benchmark 12 4 percent of the assets are misallocated and prices are approximately 27 3 percent lower dealers play an important role in reducing frictions in a market with no dealers 15 7 percent of the assets would be misallocated perhaps surprisingly in a market with no dealers prices would increase by 2 8 percent because sellers outside options improve relative to buyers thus counteracting the effects of higher search costs and slower trade on asset prices

valuing public goods with the contingent valuation method a critique of kahneman and knetsch the social stakes in the use and abuse of the contingent valuation method cvm are very high recent developments in environmental law have elevated the cvm to the status of a refutable presumption in cases brought under certain statutes it is no longer adequate for economists to sniff at the continued popularity of the cvm in such cases it is instead incumbent on economists to come to some conclusions as to the domain under which the cvm may or may not be correctly applied one should not expect a simple thumbs up or thumbs down assessment in this matter such an expectation would be naive with respect to the inherent complexity of the issue not to mention the financial incentives that expert witnesses might have to breed as if controversy in an adversarial legal system in this context the strong admonitions of kahneman and knetsch 3 kk against the casual use of the cvm must be carefully examined they present what they believe to be evidence to support the claim that the cvm suffers from an embedding effect and that any reported willingness to pay wtp is best interpreted as the purchase of moral satisfaction rather than as a measure of the value associated with a particular public good i argue that their evidence is insufficient to test the implied hypotheses that it is incorrectly reported and that it is in large measure fully consistent with received economic theory

consumers willingness to pay for renewable and nuclear energy a comparative analysis between the us and japan abstract this paper examines consumers willingness to pay for nuclear and renewable electricity as two alternatives to fossil fuels for the reduction of greenhouse gas emissions we conduct a choice experiment of consumer stated preferences on the basis of an online survey in four us states and japan after the fukushima nuclear plant accident first the results suggest that us consumers willingness to pay for a 1 decrease in greenhouse gas emissions is 0 31 per month which is similar to the results for the us a decade ago japanese consumers show a slightly lower willingness to pay of 0 26 per month second the average consumer in both countries expresses a negative preference for increases in nuclear power in the fuel mix to a greater extent in japan third renewable energy sources were endorsed by both us and japanese consumers who show a willingness to pay 0 71 and 0 31 per month for a 1 increase in the use of renewable source energy this study also examines the differences in respondents characteristics approximately 60 of the us respondents who did not change their perception concerning the use of nuclear energy subsequent to the fukushima nuclear crisis have almost no preference for variation in nuclear power which is in stark contrast to the japanese respondents opposition to nuclear energy

optimal sequential investment when capital is not readily reversible when investment opportunities arrive one at a time and are reviewed sequentially a corporation s optimal policy differs from a standard net present value rule if the corporation exercises control over an industry state variable and control is costly the first condition presupposes a degree of market power for the firm the second occurs if corporate investment decisions are imperfectly reversible to address the problem of optimal investment in this context a firm s investment decisions are modeled as a markov reward process the causes of economic irreversibility are discussed and general propositions concerning the optimal investment policy are derived these propositions are then applied to the optimization of an exploration program by an oligopolistic firm a price leader under particular demand and distributional assumptions solutions for the optimal decision rule and the value of the exploration program are obtained and their properties examined current investment may affect future opportunities by creating growth opportunities as defined by myers 16 see also spence 25 or by reducing the value of an existing opportunity set despite the known potential for these interactions capital budgeting techniques such as net present valuation scenario planning and monte carlo simulation focus exclusively on the stand alone value of an investment the capacity for modeling interactions is present in the multiperiod models of merton 16 bogue and roll 5 and others the absence of applications however is evidence that actual economic interactions between current and future opportunities are not well understood this paper develops a model of a firm facing a sequence of interdependent growth opportunities opportunities have positive net present values because the firm exercises market power in its product market current investment changes the value of future opportunities through its effect on a product market variable the model is used to examine the impact of demand industry structure and technology on optimal investment rules and on the value of aggregate growth

valuing biodiversity for use in pharmaceutical research biodiversity prospecting has been touted as a mechanism for both discovering new pharmaceutical products and saving endangered ecosystems it is unclear what values may arise from such activities however evidence from transactions is incomplete and existing theoretical models are flawed we calculate an upper bound on the value of the marginal species even under favorable assumptions this bound is modest slightly modified assumptions lead to drastically lower estimates we extend our findings to the value of the marginal hectare of habitat and find that the incentives for habitat conservation generated by private pharmaceutical research are also at best very modest

valuing nature in a general equilibrium abstract we explore the consequences of modeling the demand for environmental quality improvements as a fully integrated part of a general equilibrium demand system in an applied general equilibrium or cge analysis demand for non market goods depends on a full range of relative prices as well as environmental outcomes we simulate the effects of reducing two air pollutants to improve human health and three ecosystem services provided to households the ecosystem services make non separable contributions to household utility we find that willingness to pay measures of use based ecosystem services are impacted by changes in demand for complementary market goods demand for these goods shifts due to pollution reductions that enhance ecosystem services partial equilibrium estimates of these use values can be measured with substantial error if they fail to account for the general equilibrium adjustments caused by pollution over 300 calibrations of the model identify the model features important to these errors we find that effects on ecosystem services associated with non use values have important implications for the feedback effects on use related measures of economic tradeoffs this is due to how our model integrates market and non market effects reflecting the non market services importance to general equilibrium market outcomes

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

enhanced geospatial validity for meta analysis and environmental benefit transfer an application to water quality improvements meta regression models are commonly used within benefit transfer to estimate willingness to pay wtp for environmental quality improvements theory suggests that these estimates should be sensitive to geospatial factors including resource scale market extent and the availability of substitutes and complements valuation meta regression models addressing the quantity of non market commodities sometimes incorporate spatial variables that proxy for a subset of these effects however meta analyses of wtp for environmental quality generally omit geospatial factors such as these leading to benefit transfers that are invariant to these factors this paper reports on a meta regression model for water quality benefit transfer that incorporates spatially explicit factors predicted by theory to influence wtp the metadata are drawn from stated preference studies that estimate per household wtp for water quality changes in united states water bodies and combine primary study information with extensive geospatial data from external sources results find that geospatial variables are associated with significant wtp variations as predicted by theory and that inclusion of these variables reduces transfer errors

durable goods oligopoly with secondary markets the case of automobiles we study the effects of durability and secondary markets on equilibrium firm behavior in the car market we construct a dynamic oligopoly model of a differentiated product market to incorporate the equilibrium production dynamics that arise from the durability of the goods and their active trade in secondary markets we derive an econometric model and estimate its parameters using data from the automobile industry over a 20 year period our estimates are used to provide a measure of the competitive importance of the secondary market

fat tails and truncated bids in contingent valuation an application to an endangered shorebird species a yes response function in a contingent valuation study is said to have fat tails if it has a high and slowly declining yes response rate at high bid levels truncated bids refer to the practice of dropping high bid offers before a yes response rate of near zero is reached this is a common practice in contingent valuation we explore the extent and implications of fat tails and truncated bids in a study of an endangered shorebird species we find among other things that mean willingness to pay is quite sensitive to the highest bid offered so much so that the choice of highest bid nearly dictates outcomes

part whole bias in contingent valuation will scope effects be detected with inexpensive survey methods the purpose of this paper is to test for scope effects with the contingent valuation method we use data from a telephone survey focusing on water quality improvements in the albemarle and pamlico sounds in north carolina we find that the willingness to pay estimates are sensitive to the scope of the policy these results suggest that the use of inexpensive survey methods may not be the cause of the failure to detect scope effects in some recent contingent valuation studies

the market for used cars new evidence of the lemons phenomenon the lemons model assumes that owners of used cars have an information advantage over potential buyers with respect to the quality of their vehicles owners of bad cars try to sell them to ill informed buyers while owners of good cars hold on to theirs consequently the quality of traded automobiles tends to be sub average in contrast to previous empirical work the following article investigates the behaviour of both buyers and sellers testing for adverse selection by sellers and for quality uncertainty among buyers with a sample consisting of all 1985 cars registered in the swiss canton of basle city over the period 1985 to 1991 our data supports both adverse selection and buyer uncertainty suggesting that a lemons problem exists

asking for individual or household willingness to pay for environmental goods implication for aggregate welfare measures the aggregate welfare measure for a change in the provision of a public good derived from a contingent valuation cv survey will be higher if the same elicited mean willingness to pay wtp is added up over individuals rather than households a trivial fact however once respondents are part of multi person households it becomes almost impossible to elicit an uncontaminated wtp measure that with some degree of confidence can be aggregated over one or the other response unit the literature is mostly silent about which response unit to use in wtp questions and in some cv studies it is even unclear which type has actually been applied we test for differences between individual and household wtp in a novel web administered split sample cv survey asking wtp for preserving biodiversity in old growth forests in norway two samples are asked both types of questions but in reverse order followed by a question with an item battery trying to reveal why wtp may differ we find in a test between samples that the wtp respondents state on behalf of their households is not significantly different from their individual wtp however within the same sample household wtp is significantly higher than individual wtp in particular if respondents are asked to state individual before household wtp our results suggest that using individual wtp as the response unit may overestimate aggregate wtp thus the choice of response format needs to be explicitly and carefully addressed in cv questionnaire design and further research in order to avoid the risk of unprofitable projects passing the benefit cost test

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

an ss model with adverse selection we present a model of the market for a used durable in which agents face fixed costs of adjustment the magnitude of which depends on the degree of adverse selection in the secondary market we find that unlike typical models the ss bands in our model contract as the variance of the shock increases we also analyze a dynamic version of the model in which agents are allowed to make decisions that are conditional on the age of the durable we find that as the durable ages the lemons problem tends to decline in importance and the ss bands contract

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

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

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

financing durable assets this paper studies the nancing of durable assets in a model with collateral constraints due to limited enforcement durability aects the ease of nancing we show that more durable assets require larger down payments of internal funds per unit of capital making them harder to nance because durability raises the price of an asset and hence the overall nancing need more than its collateral value thus nancial constraints have a bigger impact on purchases of more durable capital such as land structures and durable equipment this basic insight has implications for the choice between new and used capital technology adoption and the rent versus buy decision since new assets are more durable than used ones unconstrained borrowers buy new assets and sell them when they are used while constrained borrowers purchase used assets financial constraints inhibit technology adoption as constrained borrowers may adopt less durable low quality assets that are otherwise dominated technologies more durable assets are more likely to be rented given their larger nancing need legal enforcement aects trade in durable assets and technology adoption with weak legal enforcement economies being net importers of used assets and investing a larger fraction in less durable low quality assets

strategic learning and entry equilibrium abstract this paper describes the nature of equilibrium for a dynamic game between a monopolist and an entrant who adopts a learning strategy for cost reduction the learning process is characterized as a continuous time poisson process where each success reduces a part of the entrant s cost difference with the incumbent the entrant chooses a stream of expenditure after every success to control the instant probability of the next success the techniques of semi markov decision processes are used to characterize equilibrium learning decisions at every stage distribution of entry times and the effects of subsidies technical progress etc on pre entry and post entry learning strategies

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

turnover of used durables in a stationary equilibrium are older goods traded more this paper develops a dynamic model with transaction costs to determine the equilibrium resale pattern in a market for a durable good the key result is that the probability of resale is nonmonotonic in the age of the good trade volume is relatively low in the very beginning and in the middle of a good s life this result helps explain observed variations of resale rates across vintages for the u s market of used cars

durable goods leasing in the presence of exporting used products to an international secondary market abstract with the rapid growth of global trade used durable goods from wealthy countries increasingly find their way into the secondary market of less wealthy countries exporting used products to a physically separate market not only removes cannibalization for new products at home but also fetches additional revenue in this paper we investigate the implications of exporting used products to international secondary markets in the durable goods industry we find that such a practice may significantly stimulate new product lease on the home market an effect in which the market attractiveness and product quality are mutually reinforcing we discover that removing cannibalization pressure is more of a priority than generating additional revenue while exporting used products if the export is carried out by an agent who exports used products bought from oem original equipment manufacturer we observe the disadvantage of double marginalization in a channel structure which slows down export and causes quantity distortion and also reduces the effectiveness of government stimulus however if the agent and oem set export price based supply and demand equilibrium this reduces the quantity distortion one special characteristic of used products trade across borders is the involvement of governments on both sides of the border the government measures include penalties imposed on aging durable goods and trade barriers we find that legislation of penalizing used products on the domestic market can stimulate export but it does not have an intended effect of stimulating new products produced at home the channel structure worsens the problem

dominant firms and their alleged decline abstract by way of a survey of recent literature on the theory of strategic competition this paper focuses on the question of whether dominant firms decline the traditional argument suggesting decline is found to be based on a rather unsatisfactory modelling of dominance and more acceptable conceptualizations suggest that such privileged positions will persist

sequencing and the adding up property in contingent valuation of endangered species are contingent non use values economic values this paper presents tests of the theoretical validity of the contingent valuation cv method the validity of cv is especially a concern when involving environmental goods with a predominant non use value one test of theoretical validity is the adding up property that implies that a specific good should be equally valued irrespectively of it is being valued directly or built up sequentially in this cv study four independent sub samples stated willingness to pay for the same composite good or package using different sequences one sub sample valued the composite good directly while two sub samples faced built up sequences valuing first subsets of this composite good a fourth sub sample valued the composite good from a dividing out approach facing first the valuation of a larger multi package theoretically expected sequencing effects were observed the subset goods obtained higher values earlier in a sequence and the dividing out approach decreased the stated value for the composite good most importantly these cv data did pass the tests of the adding up property

economic analysis and the quest for competitive advantage curred in the past decade between applied microeconomists and those who study business strategy business strategists have cast up a series of questions for industrial economists who have responded with numerous applications of economic theory and quantitative research methods this interchange has been fruitful and indeed more fruit remains for the picking i shall argue for centering the collaborative effort on what may be called committed competition rivalrous moves among incumbent producers that involve resource commitments that are irrevocable for nontrivial periods of time most concerns of business strategy are with policy choices that

when do secondary markets harm firms to investigate whether secondary markets aid or harm durable goods manufacturers we build a dynamic model of durable goods oligopoly with transaction costs in the secondary market calibrating model parameters using data from the us automobile industry we find the net effect of opening the secondary market is to decrease new car manufacturers profits by 35 percent counterfactual scenarios in which the size of the used good stock decreases such as when products become less durable when the number of firms decreases or when firms can commit to future production levels increase the profitability of opening the secondary market

balladurette and juppette a discrete analysis of scrapping subsidies this paper studies the effects of subsidies on durable goods markets in particular we focus on a recent policy in france in which the governments of balladur and juppe subsidized the replacement of old cars with new ones to study this policy we construct a dynamic stochastic discrete choice model of car ownership at the household level the resulting decision rules and equilibrium conditions are used to estimate the underlying parameters of the model using aggregate data these policy functions are used to evaluate the short and long run effects of the french policies we find that these policies do stimulate the automobile sector in the short run but through the induced changes in the cross sectional distribution of car ages create the basis for subsequent low activity further while these policies increase government revenues in the short run revenues in the long run are lower relative to a baseline without intervention

trade in used equipment with heterogeneous firms this paper examines the pattern of trade in used asset markets where firms have differing factor prices and utilization rates of capital goods depreciation is modeled as an increase in down time as machines age and a measure of comparative advantage is derived that will explain the pattern of trade when there are two types of firms it is shown that with heterogeneous firms the price of used machines will reflect the characteristics of firms as well as the productivity of used machines and the implications of this result for the study of depreciation are discussed finally the relationship between firm characteristics and choice between purchasing new and used truck tractors is presented as an illustration of the predictions of the model

investment decisions with economies of scale and learning economists in an antitrust case have at their disposal quite a large bag of tools and truisms but for the most part these are derived from studies of static models in many industries the policy issues concern the implications of firm behavior on market structure and performance over time a case in point is a recent federal trade commission complaint against the dupont corporation the ftc alleged that dupont had engaged in a strategy designed to monopolize the market for titanium dioxide better known as the coloring agent in white paint the alleged strategy was in essence what some would recognize as the boston consulting group story when a firm has a lead in an industry with significant learning economies the firm should price below competitors costs and expand to take further advantage of learning effects and in the process to increase market share this paper summarizes the results of an analysis of dynamic competition with scale and learning effects the research is a preliminary exploration all results are obtained under rather special assumptions about the production technology the effects of experience on costs and the strategic interactions between firms two kinds of strategic behavior are considered in the first case each firm takes the production decisions of competitors as given the nash assumption in the second case firms consider pre emptive capacity investments taking into account that competitors will alter their future investment plans to achieve nonnegative profits we call this a competitive stackelberg cs game using the maximization of net surplus as a socially optimal benchmark neither form of competition yields an efficient outcome when new investment exhibits increasing returns to scale in the absence of learning effects smaller firms in a nash competition have a greater incentive to add new capacity than do larger firms and the equilibrium industry structure approaches equal market shares introducing learning effects in the nash game causes a tendency toward increased concentration but monopoly is not an inevitable consequence the cs game is more competitive than the nash game in the sense that firms compete for the right to invest at each instant of time with identical firms and no learning effects the market structure in a cs equilibrium is indeterminate although the sequence of industry investments is well defined introducing firm specific and nonstochastic learning has a dramatic effect on the cs equilibrium all new investment is undertaken by a single firm even if the learning economies are small moreover the level of output could be lower and price higher in a cs equilibrium than it would be in a nash equilibrium in this sense more competition can lead to a lower rate of output over time

values in the wind a hedonic analysis of wind power facilities the siting of wind facilities is extremely controversial this paper uses data on 11 331 property transactions over nine years in northern new york state to explore the effects of new wind facilities on property values we use a fixed effects framework to control for omitted variables and endogeneity biases we find that nearby wind facilities significantly reduce property values in two of the three counties studied these results indicate that existing compensation to local homeowners communities may not be sufficient to prevent a loss of property values jel q51 q53

adverse selection in durable goods markets we present a dynamic model of adverse selection to examine the interactions between new and used goods markets we find that the used market never shuts down the volume of trade can be large and distortions are lower than previously thought new cars prices can be higher under adverse selection than in its absence an extension to several brands that differ in reliability leads to testable predictions of the effects of adverse selection unreliable brands have steeper price declines and lower volumes of trade we contrast these predictions with those of a model where brands physically depreciate at different rates

new or used investment with credit constraints abstract used capital is cheap up front but requires higher maintenance payments later on we argue that the timing of these investment cash outflows makes used capital attractive to financially constrained firms since it is cheap when evaluated using their discount factor in contrast it may be expensive from the vantage point of an unconstrained agent we provide an overlapping generations model and determine the price of used capital in equilibrium agents with less internal funds are more credit constrained invest in used capital and start smaller firms empirically we find that the fraction of investment in used capital is substantially higher for small firms and varies significantly with measures of financial constraints

environmentalism stimulus and inequality reduction through industrial policy did cash for clunkers achieve the trifecta the 2009 american cash for clunkers program which subsidized consumers who scrapped old vehicles and purchased new vehicles was promoted by appealing to multiple constituencies we evaluate the policy and alternatives according to its stated goals emissions reductions economic stimulus and reducing inequality we calibrate a dynamic partial equilibrium portfolio model to match consumer expenditure data from 1998 to 2011 focusing on heterogeneity across cars and trucks we find the program generated 0 17 in environmental benefits 0 28 in consumer surplus and 0 31 in net discounted additional spending per subsidy dollar since subsidies largely went to middle income infra marginal consumers the program exacerbated consumption inequality we evaluate alternative policy designs and find no policy which simultaneously improves all outcomes jel h23 l52 l92 d63

price and quality discrimination in durable goods monopoly with resale trading abstract we examine a durable goods monopolist s optimal dynamic price and product quality strategy when buyers are rational and can trade used durables among themselves in contrast to the usual credibility problem of the durable goods monopolist intertemporal quality discrimination introduces a time inconsistency problem of not raising prices against high valuation consumers who delay purchase for quality upgrades resale trading ameliorates this time inconsistency problem and allows the monopolist to effectively price discriminate especially when the buyers are patient the monopolist s optimal price and quality offers in the new good market exhibit complex dynamic patterns and new good prices can fall as product quality improves even in the absence of entry threats or learning economies initial quality distortions are followed by steady state quality allocations that are always efficient for the high valuation buyers but sometimes also for the marginal consumer types both the resale trading frequency and the price discount for secondhand goods are driven by the pace of strategic quality obsolescence in the new good market

quality standards for used durables an indirect subsidy abstract we construct a theoretical framework to study the impact of quality standards for used durable goods on trade ows pro ts and consumer welfare we show that asymmetric quality standards generate trade in used goods from high to low standard countries while at the same time reducing trade in new goods producers in the exporting country bene t from this change while consumers lose in the importing country consumers are better off but domestic industry is hurt these ndings suggest that quality standards on used goods may be a powerful policy tool whose use should be monitored by the wto

imperfect durability and the coase conjecture this article considers a market served by a monopolist who sells a durable good that depreciates stochastically over time we show that there exist three types of stationary equilibria a coase conjecture equilibrium a monopoly equilibrium and a reputational equilibrium when the depreciation rate is low the coase conjecture equilibrium is the unique equilibrium for intermediate values of the depreciation rate all three equilibrium types coexist when the depreciation rate is high the monopoly equilibrium is the unique equilibrium consequently when selling a good of sufficiently low durability the monopolist does not lose any of her monopoly power furthermore the steady state output in the reputational equilibrium falls below the monopoly quantity hence in durable goods markets welfare losses due to monopoly power may be larger than in markets for perishables

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

lumpy investment in a growing differentiated market optimum consider now a growing differentiated market that is a market for a chamberlinian group of differentiated commodities which is expanding over time as the size of the market increases it will be profitable for new firms to enter with new varieties of the industry product the same strategic considerations apply as with a homogeneous industry investment in new products involves irreversible and indivisible costs thus decisions of a potential entrant depend on the past decisions of earlier entrants and on the decisions of future entrants as to entry date price and type of product produced in this way the equilibria that we consider here differ from nash equilibria in static models in that the profit flows accruing to incumbent firms depend on the behaviour of future entrants one consequence of this for example is that the nash equilibrium we consider here involves pure profit for all producing firms when a reasonably large number of products is established in the market the industry can be regarded as monopolistically competitive it is appropriate then to pose in this context traditional questions concerning the welfare optimality of monopolistic competition will there be too much variety with each product produced inefficiently the dynamic aspect of the problem means that it is perfectly possible in principle to have excessive variety at one stage in the growth of a market and insufficient variety at some different stage note that one relevant decision variable is the introduction date of a new product or of a whole sequence of products provided that variable costs can be covered a particular product once introduced will not leave the set at a later date thus if we take any given chronological sequence of product types and

referendum models and economic values theoretical intuitive and practical bounds on willingness to pay innovations in the estimation of referendum type contingent valuation models have led to willingness to pay wtp measures inconsistent with consumer preferences and unbounded from above or below we propose a set of criteria which guarantee a bounded measure of wtp the criteria reject the traditional random utility model with unrestricted error terms in favor of the random wtp model with bounds on wtp once wtp is bounded by zero and income the form of the distribution is less consequential a new model for wtp is developed based on the beta distribution and is compared to previously estimated models

adjustment of consumers durables stocks evidence from automobile purchases this paper tests an optimal s s rule in household durable purchases and examines directly the resulting aggregate expenditure dynamics the observed decision rule responds to income uncertainty and growth as predicted by an s s model resulting from transactions costs tests against liquidity constraints find that about half the households purchase according to an optimal s s rule aggregating the s s rule over households produces a cross section distribution of durables holdings the empirical distribution is similar to that predicted theoretically as is its response to aggregate shocks furthermore simulations of aggregate expenditure based on the household distribution exhibit dynamics consistent with those observed in the 1980s

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

the adding up test in an incentivized value elicitation mechanism the role of the income effect in the context of testing the construct validity of stated preference studies some researchers advocate the use of an adding up test designed to gauge whether elicited values are sufficiently sensitive to a change in the scope i e size of a good crucial to the applicability of this test in practice which relies on endowing a subsample of respondents with a good free of charge is that the income effects due to endowment are negligible in this study we apply the adding up test in an experimental value elicitation format to examine the potential effect of endowment as part of the test design on the adding up property of elicited values the results show that the adding up property can be affected by free provision of part of the bundle
