inflation and the fiscal limit abstract we use a rational expectations framework to assess the implications of rising debt in an environment with a fiscal limit the fiscal limit is defined as the point where the government no longer has the ability to finance higher debt levels by increasing taxes so either an adjustment to fiscal spending or monetary policy must occur to stabilize debt we give households a joint probability distribution over the various policy adjustments that may occur as well as over the timing of when the fiscal limit is hit one policy option that stabilizes debt is a passive monetary policy which generates a burst of inflation that devalues the existing nominal debt stock the probability of this outcome places upward pressure on inflation expectations and poses a substantial challenge to a central bank pursuing an inflation target the distribution of outcomes for the path of future inflation has a fat right tail revealing that only a small set of outcomes imply dire inflationary scenarios avoiding these scenarios however requires the fiscal authority to renege on some share of future promised transfers

how useful are the forecasts of intergovernmental agencies the imf and oecd versus the consensus this study compares the accuracy and information content of economic forecasts for g7 countries made in the 1990s by the oecd and imf the benchmarks for comparison are the average forecasts of private sector economists published by consensus economics with few exceptions the private sector forecasts are less biased and more accurate in terms of mean absolute error and root mean square error formal tests show these differences are statistically significant for forecasts of real growth and production less so for forecasts of inflation and unemployment overall there appears little information in the oecd and imf forecasts that could be used to reduce significantly the error in the private sector forecasts

qualitative assessment of eco labels on fresh produce in flanders belgium highlights a potential intention performance gap for the supply chain abstract when it comes to making sustainable food purchasing choices consumers trust on information provided to them by eco labels this article studies the labels for fresh produce available to consumers in flanders belgium concluding that the existing labelling landscape fails at enabling consumers to make adequate decisions for purchasing environmentally sound food a consumer survey supports the need for additional information on the sustainability of fruits and vegetables a potential intention performance gap is found for producers and in the wider sense for the entire supply chain since current labels found on fresh produce are input or practice based labels farmers adhering to those labels can be considered as having the intention to produce sustainably however this intention alone cannot guarantee good environmental performance in order to close the potential intention performance gap for the supply chain and provide more adequate information to consumers we conclude that performance based labels covering the entire food chain of fresh produce using the life cycle assessment approach lca and including situational parameters such as time of consumption origin and production and distribution mode are indispensable

enterprises compliance with government carbon reduction labelling policy using a system dynamics approach abstract a carbon reduction labelling scheme is an effective policy tool for motivating enterprises or organizations to reduce their life cycle based carbon emissions to benefit the environment this paper uses system dynamics to model enterprises compliance with a combined government policy instrument for a carbon reduction labelling scheme that is government subsidies and economic sanctions a case study of paper enterprises in china is provided to demonstrate the application of the proposed model in which two optional technological plans to reduce the enterprises carbon emissions are examined the technological plans are categorized as a low cost and high cost plan the simulation results show that both the technological plans are vulnerable to the combined policy making and the high cost plan shows superior environmental performance for carbon emissions reduction however the enterprises are more inclined to choose the low cost plan because of superior economic performance the study offers insights to help enterprises select optimal actions on carbon emissions reduction and to inform government of possible sustainable policy design to promote low carbon development the model limitations are discussed as a basis for further improvements in low carbon development

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

egyptian consumers willingness to pay for carbon labeled products a contingent valuation analysis of socio economic factors abstract carbon emissions from products contribute to anthropogenic climate change because of the growing concern over the environmental impact of production and consumption of consumer goods carbon footprint information started to appear on labels of several products in this paper we use both parametric and non parametric econometric models in order to estimate egyptian consumers willingness to pay wtp for carbon labeled products contingent valuation methods based on log logistic log normal and weibull regression models revealed that consumers in egypt are willing to pay a price premium of approximately 75 egyptian pounds ep for carbon labeled products based on the single bound dichotomous choice sbdc model and up to 90 ep based on the double bound dichotomous choice dbdc model from a socio economic perspective results have also revealed that income age gender and educational level have a significant influence on the respondent s wtp implications of this study highlight the fact that understanding consumers preferences for eco friendly products may play an important role in formulating environmental policy changes to face complex problems as diverse as environmental pollution or global climate change

finnish consumer perceptions of carbon footprints and carbon labelling of food products abstract the aim of this study was to explore how finnish consumers perceive the communication of carbon footprints for food products the study comprised five semi structured focus groups and an online survey of 1010 respondents the study showed that the term product carbon footprint is familiar to many but there is substantial misunderstanding of its meaning only 7 of the respondents linked product carbon footprint spontaneously to greenhouse gas emissions associated with the product and an additional 5 of the respondents linked it to climate change there are positive attitudes towards carbon labels 90 stated that a carbon footprint would have at least a little impact on their buying decision but the information became meaningful only when many other purchasing criteria such as price and taste were satisfied furthermore 86 preferred carbon labels that allow comparisons of carbon footprints to be made among food products but there is divergence on perceived needs for carbon label content

information disclosure policies evidence from the electricity industry i introduction developed nations environmental policies have evolved substantially in the past several decades early pollution control programs involved command and control approaches policies then frequently included pollution charges tradable permits and other market based instruments most recently a third wave of environmental policy has emerged that emphasizes information provision as an integral part of the risk mitigation strategy here government regulation is replaced or augmented by publicly provided information presumed to assist more cost effective private market and legal forces common examples include the toxics release inventory lead paint disclosures drinking water quality notices and eco labels the empirical effects of such programs however remain largely undetermined this paper examines the impact of a prominent mandatory disclosure program on the fuel mix percentages of large electric utility corporations the prominence of mandatory information policies is not restricted to environmental arenas for example developed countries equity markets generally require firm level financial information provision in many countries agricultural goods require country of origin and other health labels domestic colleges and universities are required by law to inform current and prospective students of crime statistics equity data and performance metrics even significant medical errors must now be disclosed to the community there are several potential advantages of information provision policies and theory suggests that disclosure programs may effectively achieve their goals healy and palepu 2001 provided a survey of the evidence in capital markets brouhle and khanna 2007 demonstrated that information provision can improve product quality in the environmental area kennedy laplante and maxwell 1994 arora and gangopadhyay 1995 maxwell lyon and hackett 2000 kirchhoff 2000 and khanna 2001 showed that the provision of information about pollution may correct a market failure improve performance and enhance welfare despite the literature s theoretical findings the empirical effects of disclosure programs remain inconclusive early studies of securities regulation found mixed results see stigler 1964 robbins and werner 1964 and benston 1973 a more recent literature suggested that disclosure programs in financial markets can achieve their desired effects la porta and lopez de silanes 2006 and greenstone oyer and vissing jorensen 2006 found that both market size and market returns were positively influenced by mandatory disclosure programs in product quality settings chipty and witte 1998 established that resource and referral agencies significantly influenced childcare prices but had no impact on the quality of care in contrast jin and leslie 2003 found that mandatory hygiene grade cards positively affected restaurant quality and health outcomes studies of environmental performance yielded similarly mixed results desvousges smith and rink 1992 found that information based programs influenced attitudes favorable to radon testing but testing itself only increased when mass media dissemination was coupled with community based implementation programs konar and cohen 1997 and khanna quimio and bojilova 1998 found that stock movements associated with toxics release inventory tri announcements led to increased abatement and reduced emissions however bui 2005 found that the declines in emissions after tri reporting events may have been attributable to regulation rather than investor pressure bennear and olmstead 2006 found that drinking water quality notices lowered violations for some systems but not others this paper is the first empirical economic study of the impacts of mandatory information provision in the electric utility industry the disclosure programs considered here differ significantly from the tri information programs examined previously

analyst forecasts and herding behavior the use of analyst forecasts as proxies for investors earnings expectations is commonplace in empirical research an implicit assumption behind their use is that they reflect analysts private information in an unbiased manner as demonstrated here this assumption is not necessarily valid there is shown to be a tendency for analysts to release forecasts closer to prior earnings expectations than is appropriate given their information further analysts exhibit herding behavior whereby they release forecasts similar to those previously announced by other analysts even when this is not justified by their information these results are shown to have interesting empirical implications article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

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

predicting consumer demand responses to carbon labels abstract providing carbon footprint labels for all food products is a daunting and potentially infeasible project knowing how consumers substitute away from high carbon goods and what they choose as substitutes is essential for understanding which goods are likely to result in meaningful reductions in carbon emissions this paper proposes a model to systematically estimate how consumers will respond to information from a carbon footprint label our model uses consumers value of their individual carbon footprint with own and cross price elasticities of demand data on carbon emissions from life cycle analysis to simulate shifts in consumer demand for 42 food products and a non food composite and subsequent changes in carbon emissions from different labeling schemes our simulation results have several findings including 1 carbon labels can reduce emissions but labeling only some items could lead to perverse impacts where consumers substitute away from labeled goods to unlabeled goods with a higher carbon footprint 2 carbon labels can inform consumers such that their previous beliefs about carbon footprints matter and 3 carbon labels on alcohol and meat would achieve the largest decreases in carbon emissions among the 42 food products studied

consumer acceptance valuation of and attitudes towards genetically modified food review and implications for food policy abstract an increasing set of evidence has been reported on how consumers could potentially react to the introduction of genetically modified food studies typically contain some empirical evidence and some theoretical explanations of the data however to date limited effort has been posed on systematically reviewing the existing evidence and its implications for policy this paper contributes to the literature by bringing together the published evidence on the behavioural frameworks and evidence on the process leading to the public acceptance of genetically modified gm food and organisms gmos in doing so we employ a set of clearly defined search tools and a limited number of comprehensive key words the study attempts to gather an understanding of the published findings on the determinants of the valuation of gm food both in terms of willingness to accept and the willing to pay a premium for non gm food trust with information sources on the safety and public health and ultimate attitudes underpinning such evidence furthermore in the light of such evidence we formulate some policy strategies to deal with public uncertainly regarding to gmos and especially gm food

interval estimates of non market resource values from referendum contingent valuation surveys contingent valuation methods cvm have attracted considerable attention in recent years as researchers have begun to resort to survey methods to elicit individual values for non market goods such as environmental resources or public goods cummings brookshire and schulze 1986 and mitchell and carson 1989 offer comprehensive assessments of these methods cvm survey questions come in a variety of forms one format which has proven to be popular is called the discrete choice or take it or leave it referendum or closedended question originally implemented in the literature by bishop and heberlein 1979 since respondents find it very difficult to identify precisely their true point value of access to some resource or public good open ended valuation questions can be unreliable or can discourage response in contrast most people are familiar with being confronted by a posted price for a good and with deciding whether or not they would buy at that price this is the strategy behind discrete choice cvm questions a different hypothetical price is offered to each respondent and by their yes no response to the question of whether they would be willing to pay this price the researcher gains information about their true underlying point value one persistent difficulty with the econometric techniques that are currently used most widely to analyze referendum contingent valuation data is the absence of confidence intervals for the ultimate value estimates early empirical applications approximate mean valuations using a truncated mean based on a logit model with the upper limit being the highest bid value in the sample unfortunately the variance of this estimated mean cannot easily be recovered from the numerical integration procedure commonly used to calculate the

a theory of collective reputations with applications to the persistence of corruption and to firm quality the paper is a first attempt at modelling the idea of group reputation as an aggregate of individual reputations a member s current incentives are affected by his past behaviour and because his track record is observed only with noise by the group s past behaviour as well the paper thus studies the joint dynamics of individual and collective reputations and derives the existence of stereotypes from history dependence rather than from a multiplicity of equilibria or from the existence of a common trait as is usually done in the literature it shows that new members of an organization may suffer from an original sin of their elders long after the latter are gone and it derives necessary and sufficient conditions under which group reputations can be rebuilt last the paper applies the theory to analyse when a large firm can maintain a reputation for quality 1 collective reputations collective reputations play an important role in economics and the social sciences countries ethnic racial or religious groups are known to be hard working honest corrupt hospitable or belligerent some firms enjoy substantial rents from their reputations for producing high quality products some departments are reported to treat their faculty or students fairly the paper is a first attempt at modelling the idea of group reputation as an aggregate of individual reputations a member s current incentives are affected by her past behaviour and because her track record is observed only with noise by the group s past behaviour as well the paper studies the joint dynamics of individual and collective reputations in a model in which current generations are progressively replaced by new ones and derives the existence of stereotypes from history dependence rather than from a multiplicity of equilibria or from the existence of a common trait as is usually done in the literature see section 2 for a detailed comparison with the literature it shows that new members of an organization may suffer from an original sin of their elders long after the latter are gone and it derives necessary and sufficient conditions under which group reputations can be rebuilt last the paper applies the theory to analyse when a large firm can maintain a reputation for quality let us spell out the building blocks of our theory in more detail a a group s reputation is only as good as that of its members each member is characterized by individual traits such as talent diligence or honesty past individual behaviour conveys information about these traits and generates individual reputations

a strategy experiment in dynamic asset pricing this study presents a strategy experiment in a simple dynamic asset pricing model where the current market equilibrium asset price is determined by aggregated individual expectations of next period s price after participating in an introductory laboratory experiment on expectation formation participants formulate a complete forecasting strategy these strategies are programmed and markets are simulated participants receive feedback from the results of these simulations and can adapt their strategy four rounds are played and the entire experiment lasts eight weeks a final laboratory experiment compares predictions of participants with the predictions of the submitted strategy we find that most of the participants submit complicated strategies and that strategies become more complicated over the rounds most markets converge to a steady state price only after many periods if at all the number of converging price sequences increases over the rounds these results suggest in general slow convergence and learning of the subjects over the rounds even in a stationary environment learning the correct fundamental price level turns out to be difficult an important part of the non convergence seems to be caused not by individual strategies but by the interaction of several strategies from the final experiment we conclude that the strategies are a good representation of what participants do in a laboratory experiment

implications of mandatory labeling of gm food in india evidence from the supply side abstract we assess the supply side economic implications of introducing a strict mandatory labeling policy for genetically modified gm food in india as proposed in 2006 we apply our analysis to the case of cottonseed oil and soybean oil two products that would be the first affected by such regulation we find that gm food labeling would generate adjustment and implementation costs and consumer benefits would not always be visible and would highly depend on the degree of enforcement

smoking cessation a model of planned vs actual behavior for time inconsistent consumers we offer a simple model of intertemporal choice to characterize how planned versus actual behaviors evolve for time inconsistent smokers our results suggest that smokers participation and cessation decisions are governed by the interplay between three effects the cessation effect leads smokers to advance their plans to quit smoking whereas the procrastination effect leads them to consecutively revise their planned quitting age upwards consequently the duration of smoking is effectively governed by which one of these two effects is dominant finally for certain consumer segments a threshold effect causes an all or nothing type of extreme smoking behavior based on certain critical values of present biased preferences our results provide some preliminary evidence that both marketing efforts by tobacco firms and public policy initiatives can have a significant influence on smoking behavior in particular we find that reductions in the age at which individuals start smoking may not only vastly extend their duration of smoking but also convert potential never smokers into lifetime smokers finally we estimate a hazard model using survey data from over 800 smokers to provide evidence in support of our theoretical model

a bayesian approach to double bounded contingent valuation in this paper we propose a bayesian approach to model double bounded contingent valuation data the double bounded elicitation method is interpreted as a two tier iterated process in which the subject is allowed to have a second thought about his her valuation for the environmental good prior information is modelled from the answers to the first dichotomous choice question the model is quasi bayesian q b in that the prior distribution refers to mean willingness to pay while the likelihood function refers to the proportions of a multinomial distribution this model is applied to empirical data from a contingent valuation survey involving the valuation expressed by european tourists for access to natural areas in the canary islands results show that point estimate of consumer surplus computed with the q b model does not differ substantially from single bounded model estimation in addition double bounded seems to be quite robust to the choice of the prior model of willingness to pay responses comparison with open ended suggests that the q b model might be useful to control for strategic response and starting point biases

distributional conflict in organizations abstract hierarchy can function as an instrument to channel influence activities or power struggles in organizations contrary to what has frequently been argued we show that multi divisional organizations may involve lower influence costs than single tier organizations even though they offer more scope for organizational conflict and have more executives that can be influenced these benefits derive from two effects first part of the conflict in multi divisional organizations takes place on the division level where a small number of agents fight over only a fraction of the overall prize second by grouping agents into common divisions multi divisional organizations create free rider problems in rent seeking our model sheds new light on the desirability of divestitures and the transition from the u to the m form by us corporations in the 1920s

nudging and corporate environmental responsibility a natural field experiment abstract we devise a nudging natural field experiment to test the impact of a simple form of advertising on environmentally responsible products with without the increase of the responsible product price we find that the simple use of a small shelf poster explaining the importance of buying a green product with without a concurring price increase generates significant changes in market shares for some of the product classes for both food and non food products part of the effect is generated by the reduced price elasticity of consumers to the poster plus price increase treatment

unfolding social hierarchies abstract consider a large population of finitely lived agents organized into n different hierarchical levels every period all those placed at each level are randomly matched to play a given symmetric game based on the resulting outcome a fraction of agents who within their own level attain the highest payoffs are promoted upwards on the other hand newcomers replacing those who die every period enter at the lowest level and choose irreversibly the strategy to be played for the rest of their life this choice is made with some noise by imitating one of the strategies adopted at the highest level in this setup the unique long run behavior of the system is fully characterized for the whole class of 2 2 coordination games and two alternative variations of the model the results crucially depend on the key institutional parameters and n in particular it is shown that inefficient behavior prevails in the long run even when risk dominated if promotion is only mildly selective high and the social system is quite hierarchical large n in a stylized manner these parameter conditions may be viewed as reflecting a sort of institutional deficiency that impairs economic performance journal of economic literature classification numbers c70 c72 c73 d72

consumers valuation of sustainability labels on meat there are various sustainability certifications and claims for food products that focus on environmental or ethical benefits these claims empower consumers to make informed purchasing decisions that take environmental and ethical considerations into account this paper compares consumers preferences for four types of sustainability claims related to organic meat free range animal welfare and carbon footprint using a choice experiment on a chicken breast product our results show that nine in every ten belgian consumers favor free range claims which are also valued the most highly attracting premiums ranging from 43 to 93 our study also shows that a vast majority of consumers 87 would welcome the introduction of an eu level animal welfare label the carbon footprint labels and the organic labels are less appealing to consumers who have lower willingness to pay for these labels belgian consumers prefer the national belgian organic food logo certified by a private organization to the newly introduced eu organic food logo

fiscal space and sovereign risk pricing in a currency union abstract we examine how membership in a currency union affects public debt sustainability and market assessments of default risk in eurozone countries we argue that there exist offsetting effects expectations of bailouts tend to make a given level of debt more sustainable lowering bond yields and cds rates but constraints on the use of monetary policy would tend to have the opposite effect pushing rates up especially as room for fiscal maneuver gets exhausted we develop a formal concept of fiscal space which takes account of the notion of fiscal fatigue under which there are limits to the government s ability to raise the primary surplus in response to higher debt and apply it to the eurozone countries investigating in particular how currency union membership affects cds and bond rates during both quiet and turbulent times for a given amount of fiscal space we find that in quiet times cds and bond rates for eurozone members were below what would be expected given their fiscal space a bonus from currency union membership but when the crisis erupted cds and bond yields rose more sharply for eurozone members than would be predicted based on their available fiscal space our interpretation is that sovereign bailouts did not occur with the hoped for alacrity in euro crisis countries generating sharper penalties for sovereigns that belong to a currency union

how much are people willing to pay for silence a contingent valuation study despite its major importance in the urban environment the problem of noise has received little attention from environmental economists in this paper the economic value of a noise reduction programme is evaluated the chosen technique is contingent valuation using the recently proposed one and one half bound question format this new question format reduces the potential for response bias in multiple bound formats such as the double bound model while maintaining much of its efficiency through the estimations it is found that urban residents generally value noise negatively that is households are willing to pay for a noise reduction in particular it is found that households are willing to pay approximately four euros per decibel per year a further finding is that interviewees show scope sensitivity that is households display a different willingness to pay for different degrees of noise reduction most are willing to pay more for larger decreases in the level of disturbance from noise

household willingness to pay for green electricity in urban and peri urban tigray northern ethiopia determinants and welfare effects abstract this paper set out to estimate household willingness to pay for green electric services and welfare gains attributed to such schemes for this purpose contingent valuation survey was conducted on 300 urban and peri urban households in northern ethiopia a bivariate probit model was used to elicit willingness to pay and analyze determinants of household willingness to pay on the other hand welfare gains were analyzed using consumer and producer surpluses the mean willingness to pay was estimated to be birr 12 5 0 66 usd per month per household for five years on top of monthly electricity bill among others income played positive role on willingness to pay while difference in willingness to pay behavior was observed between male and female headed households in addition distance to wood and charcoal alternative energy markets played encouraging role for willingness to pay results from the welfare analysis show that there is significant societal gain to be made both in terms of surplus for households and producers government if the previously untapped green electricity service was implemented the revenue producer surplus for the state would be instrumental in contributing to the state s endeavor to generate a much needed capital for investment in and expansion of renewable energy

what drives spreads in the euro area government bond market spreads between euro area government bond yields are related to short term interest rates which are in turn related to market liquidity to cyclical conditions and to investors incentives to take risk in theory lower interest rates are associated with lower degrees of risk aversion and smaller government bond spreads empirically the eurosystem s short term interest rates are positively related to those spreads which our econometric model finds to include significant and policy relevant default risk and liquidity risk components simone manganelli and guido wolswijk

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

how do experts forecast sovereign spreads this paper assesses how forecasting experts form their expectations about future government bond spreads using monthly survey forecasts for france italy and the united kingdom between january 1993 and october 2014 we test whether respondents consider the expected evolution of the fiscal balance and other economic fundamentals to be significant drivers of the expected bond yield differential over a benchmark german 10 year bond our main result is that a projected improvement of the fiscal outlook significantly reduces expected sovereign spreads this suggests that credible fiscal plans affect market experts expectations and reduce the pressure on sovereign bond markets in addition we show that expected fundamentals generally play a more important role in explaining forecasted spreads compared to realized spreads

controlling starting point bias in double bounded contingent valuation surveys in this paper we study starting point bias in double bounded contingent valuation surveys this phenomenon arise in applications that use multiple valuation questions indeed response to follow up valuation questions may be influenced by the bid proposed in the initial valuation question previous research have been conducted in order to control for such an effect however they find that efficiency gains are lost when we control for undesirable response effects relative to a single dichotomous choice question contrary to these results we propose a way to control for starting point bias in double bounded questions with gains in efficiency

hedonic price functions and the measurement of preferences the case of swedish wine consumers abstract a hedonic price function for wine is estimated using swedish data 1989 1991 implicit prices for quality attributes are determined not from a regression of variety price on a vector of quality attributes but rather from a regression of quantity sold adjusted for weeks of availability on price and quality attributes such a reduced form is justified by the assumption that prices and attribute contents can be taken as exogenous to the swedish consumer price elasticity is estimated to be about 1 65 holding quality constant showing that swedish consumers are highly sensitive to price estimates of the implicit valuations of quality attributes are shown to differ greatly from those obtained from the more usual hedonic regression with price as the dependent variable

on mandatory labeling of animal welfare attributes this paper assesses us resident support for mandatory labeling of animal welfare information on pork and egg products and outlines policy considerations for assessment prior to implementing any mandatory labeling policies regarding animal welfare practices results suggest consumers support mandatory labeling indicating use of gestation crates stalls and laying hen cages estimates suggest consumers would be willing to pay about 20 higher pork and egg prices to obtain this production practice information demographic and latent perception drivers of this support are highlighted multiple issues that warrant consideration prior to imposing mandatory labeling are discussed revealing lines of corresponding future research

the pricing of experience goods the example of en primeur wine the market for primeur wine in the bordeaux region allows producers to sell wine that is still in barrels as with all experience goods producers send quality signals to uninformed buyers using original data on bordeaux wines we show that the pricing behavior of producers depends to a large extent on their reputation and much less on short term changes in quality as measured by experts grades we also find that the primeur price has an informative role since a 10 increase in primeur price leads to a 3 increase in prices on the market for bottled wine

rethinking new wines implications of local and environmentally friendly labels abstract new wine production areas around the world are encountering challenges in creating a reputation for high quality products in order to help these new wine growing areas numerous labeling programs claiming local origin and environmentally friendly practices are being implemented in this study consumer response toward wine grown in a new production area such as colorado is researched using an interval probit model the mean willingness to pay wtp for colorado environmentally friendly and colorado regular wines are calculated in summary the results in this paper highlight the need to improve quality perceptions to garner a premium in differentiated wine markets as a consequence environmentally friendly labeling in wine is an inefficient marketing tool for wines perceived as low quality

consumer perceived risk model for the introduction of genetically modified food in spain abstract since the last part of the 20th century the search for new forms of cultivation and food has basically centred on the application of biotechnology giving rise to gm foods consumer acceptance is conditioned by the risk that they perceive from introducing food into their consumption habits processed through technology that they hardly understand besides information is insufficient in the consumer ambit and moreover it is influenced by ideological and ethical determining factors the factors were analysed that influence this consumer perceived risk through a structural equation model this study was conducted in spain concretely in the province of alicante located in the southeast of this country the main conclusion from this research is that the introduction of gm food into agro food markets should be accompanied by adequate policies to guarantee consumer safety these actions would allow a decrease in consumer perceived risk by taking special care of the information provided concretely relating to health for the most influential factor in consumer perceived risk from these foods is concern about health

yield spreads on emu government bonds government bond spreads we provide evidence that the movements in yield differentials between euro zone government bonds explained by changes in international risk factors as measured by banking and corporate risk premiums in the united states are more pronounced for bonds issued by italy and spain liquidity factors play a smaller role so policies meant to increase financial market efficiency do not appear sufficient to deliver a seamless bond market in the euro area the risk of default is a small but important component of yield differentials movements which signal market perceptions of fiscal vulnerability impose market discipline on national fiscal policies and may be reduced only by further convergence in debt ratios lorenzo codogno carlo favero and alessandro missale

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

organic price premium or penalty a comparative market analysis of organic wines from tuscany abstract previous literature suggests that the price of wine is a function of its intrinsic and extrinsic attributes studies have examined the price of wines from various wine producing regions using the hedonic price model to determine the correlation between wine attributes and price however few studies have examined the relationship between organic production or certification and price this study uses a hedonic pricing model to examine the price premiums associated with organic production and organic certification for tuscan red wines produced between 2000 and 2008 in both the italian and american wine markets controlling for a variety of wine attributes the analysis finds that wines produced with organic practices but not certified as organic and wines certified but not labeled as organic receive a higher price compared to conventional wine for wines with low quality ratings however as the wine s quality rating increases the positive effects of organic practices and certification on price decrease and for wine with higher quality ratings organic practices and certification is associated with lower prices relative to otherwise comparable conventional wines

are french consumers ready to pay a premium for eco labeled seafood products a contingent valuation estimation with heterogeneous anchoring could the future french eco label for fresh seafood products find its place in the french market this study employs a contingent valuation method to estimate french consumers willingness to pay wtp for eco labeled fresh seafood products we exploit original data from a survey carried out in 2010 where 626 participants responded to a double bounded dichotomous choice model through an ascending or descending bid system controlling for shift and anchoring effects in random effect probit models we significantly improve estimation of wtp and its determinants for the three species studied monkfish lobster sole in particular when using heterogeneous anchoring we show that wtp is positively correlated to respondents income and also to their environmental concern to living alone to living far from the coast and to trusting ngos or public institutions more than producer organizations to implement an eco label we also show that the mean price premiums do not differ between species finally on average the maximum premium consumers accepted to pay is approximately 10 of the product price

measuring the social value of nuclear energy using contingent valuation methodology abstract as one of the promising energy sources for the next few decades nuclear energy receives more attention than before as environmental issues become more important and the supply of fossil fuels becomes unstable one of the reasons for this attention is based on the rapid innovation of nuclear technology which solves many of its technological constraints and safety issues however regardless of these rapid innovations social acceptance for nuclear energy has been relatively low and unchanged consequently the social perception has often been an obstacle to the development and execution of nuclear policy requiring enormous subsidies which are not based on the social value of nuclear energy therefore in this study we estimate the social value of nuclear energy consumers willingness to pay for nuclear energy using the contingent valuation method cvm and suggest that the social value of nuclear energy increases approximately 68 5 with the provision of adequate information about nuclear energy to the public consequently we suggest that the social acceptance management in nuclear policy development is important along with nuclear technology innovation

sustainability labels on coffee consumer preferences willingness to pay and visual attention to attributes abstract sustainability labels are important tools that help consumers assess the sustainability aspects of food while past studies have focused on visual attention to nutrition information no study has investigated the visual attention paid by consumers to the sustainability information on food our study contributes to the need to better understand consumers attention to sustainability information when making food choices the objective was to explore the importance that consumers attach to sustainability attributes and investigate how this relates to the visual attention paid to these attributes during the choice decision and to willingness to pay wtp visual attention during the decision making process was measured in terms of fixation time and fixation count which were then analyzed in relation to the stated attribute importance our results suggest that consumer segments with differences in stated attribute importance visually attend differently to these attributes higher valued attributes also exhibited higher visual attention our results suggest that consumers who spend more time attending to and fixate more on sustainability attributes value them more

effects of carbon reduction labels evidence from scanner data we investigate the effects of carbon reduction labels using a detailed scanner data set using a difference in differences estimation strategy we find that having a carbon label has no impact on detergent prices or demand we also investigate possible heterogeneous effects of carbon labels using the synthetic control method we find no evidence to indicate that the prices for the counterfactual detergents without the label would have been any different from the prices of the carbon labeled detergents we investigate the reasons for these results and conclude that the specific design of the carbon label is responsible for its lack of success jel d12 d83 l15 q54

the social selection of flexible and rigid agents people differ in how they respond to their environment some individuals treat each situation as unique and tailor their behavior accordingly while others respond in the same manner regardless of the situation the authors objective is to explore how social systems select from such a heterogeneous population a class of simple hierarchical systems is considered which encompasses some features of corporations and electoral systems a selection process operates on this population which results in successful agents going on to compete against equally successful agents for further advancement the author characterizes the population dynamics and the type of agent that ultimately dominates copyright 1998 by american economic association

some evolutionary foundations for price level rigidity this paper shows that price rigidity evolves in an economy populated by imperfectly rational agents who experiment with alternative rules of thumb in the model firms must set their prices in face of aggregate demand shocks their payoff depends on the level of aggregate demand as well as on their own price and their neighbor s price the latter assumption captures local interactions despite the fact that the rational expectations equilibrium ree is characterized by a simple pricing rule that firms can easily adopt the economy does not converge to the ree for all parameter values when the volatility of monetary innovations is low and interactions among firms are high the aggregate price level exhibits rigidity in that it does not fully react to contemporaneous aggregate demand shocks we discuss the role of the nature of experimentation and of path dependence driven by interactions in explaining these results

consumption process and multiple valuation of landscape attributes abstract environmental valuation can be seen as a process which evolves as individuals reflect on their consumption experience in this paper we consider how environmental values could change as the subject has reached the end of the consumption process a split sample comparison is conducted for estimating the values tourists give to a set of landscape attributes the first subsample was taken on site as subjects were on a tour contemplating the landscape of the island of gran canaria canary islands the second subsample was contacted at the airport when individuals were about to leave the tourist enclave since landscapes are complex environmental goods we utilize and compare a multiple contingent valuation cv approach with the stated preference approach of contingent ranking the results show that the influence of the consumption experience depends on the valuation method and the consideration of interaction effects in the model the valuation functions were not stable across both sites for most of the models considered and some of the attributes changed their values between the two points of the consumption process interaction effects were more relevant with the contingent ranking model suggesting that cv is a more limited approach in a context of multiple valuation

optimizing cooperative carbon emission reduction among enterprises with non equivalent relationships subject to carbon taxation abstract getting enterprises to reduce carbon emissions cooperatively is an effective way of sharing the burden of carbon taxation it is easier for core enterprises to promote cooperation because of their dominant positions in the supply chain the main goal of this paper is to provide a potential method for the core enterprise to organize this cooperation successfully we explore how core enterprises should allocate their reduction investments and coordinate the selection of technology upgrade strategies so as to maximize their profits without disrupting the profits of cooperating enterprises for a supply chain where there are non equivalent relationships between enterprises the main hypotheses are that each enterprise only produces one product and each production process in each enterprise can only select one production technology and the intermediate products are mainly traded among cooperative enterprises a model based on independent carbon emission reduction model i is first constructed and used to analyze each enterprises basic information when they reduce carbon emission without cooperation considering total costs profits and so on then based on this information a model including cooperation is proposed model ii in model ii the enterprises are divided into core and cooperative enterprises and both capital and technical cooperation are considered a multi agent system is presented to simulate the negotiations between the enterprises and is then used to solve model ii finally a numerical example is considered to examine the feasibility of the proposed model the results indicate that a cooperative carbon emission reduction strategy has more advantages than the independent carbon emission reduction approach a notable advantage is that it can further rationalize the emission reduction structure of the supply chain through rational allocation of reduction investments and thus further restores profits

willingness to pay for renewable energy evidence from a contingent valuation survey in kenya a modern form of energy in particular electricity for household use is an important vehicle in alleviating poverty in developing countries however access and costs of connecting to this service for most poor in these countries is inconceivable policies promoting electricity connection in rural areas are known to be beneficial in improving the socio economic and health well being for households this paper examines willingness to pay wtp for rural electrification connection in kisumu district kenya using the contingent valuation method cvm a nonparametric and a parametric model are employed to estimate wtp values for two electricity products grid electricity ge and photovoltaic pv electricity the results indicate that respondents are willing to pay more for ge services than pv and households favoured monthly connection payments over a lump sum amount some of the policies suggested in this paper include subsidizing the connection costs for both sources of electricity adjusting the payment periods and restructuring the market ownership of providing rural electricity services

how does liquidity affect government bond yields the paper explores the determinants of yield differentials between sovereign bonds using euro area data there is a common trend in yield differentials which is correlated with a measure of aggregate risk in contrast liquidity differentials display sizeable heterogeneity and no common factor we propose a simple model with endogenous liquidity demand where a bond s liquidity premium depends both on its transaction cost and on investment opportunities the model predicts that yield differentials should increase in both liquidity and risk with an interaction term of the opposite sign testing these predictions on daily data we find that the aggregate risk factor is consistently priced liquidity differentials are priced for a subset of countries and their interaction with the risk factor is in line with the model s prediction and crucial to detect their effect

testing the rationality of price forecasts new evidence from panel data this paper tests the rationality of individual price forecasts in a panel of professional forecasters here unlike in most previous studies rationality is not rejected the results here differ because 1 using individual forecasts avoids aggregation bias 2 comparison of forecasts to initial data avoids bias due to data revision 3 the professional forecasters have economic incentives to state their expectations accurately and 4 a new covariance matrix estimator consistent when forecast errors are correlated across individuals is used copyright 1990 by american economic association

empirical study of the willingness of consumers to purchase low carbon products by considering carbon labels a case study abstract due to the severe environmental problems caused by the rapid development of the global economy and high consumption rates many countries and organizations are trying to identify methods such as carbon labeling for guiding low carbon consumption by residents in order to actively respond to global climate change as a method for identifying the greenhouse gas emissions produced during the full life cycle of a product the effects of carbon labels on low carbon consumption behavior by different types of consumers is worthy of investigation first this study reviews the relevant theories and research into carbon labels and the willingness of consumers to buy low carbon products by combining grounded theory with classical theory the carbon label is subdivided into the degree of carbon label understanding acceptability of carbon labels and credibility of carbon labels which are then employed to construct a theoretical model of the factors that affect the willingness of consumers to purchase low carbon products next using data collected with a questionnaire pearson s correlation coefficient and logistic regression analysis were used to identify the main factors that influence the willingness of consumers to buy low carbon products finally the variance and mean analysis were calculated to test the differences among demographic variables and situational factors that determine the willingness of consumers to buy low carbon products which allowed us to modify the theoretical model accordingly the results indicate the following 1 the degree of carbon label understanding acceptability of carbon labels credibility of carbon labels attitudes toward purchasing low carbon products perceived effectiveness of low carbon consumption social norms reference groups the price of low carbon products and economic incentives were all important factors that influenced the willingness of consumers to buy low carbon products 2 among the carbon label related factors the degree of understanding acceptability of carbon labels and credibility of carbon labels had positive relationships with the willingness to purchase low carbon products where the higher acceptability and credibility of carbon labels as well as a better understanding of carbon labels or low carbon knowledge were associated with a greater willingness to purchase low carbon products 3 the willingness to purchase low carbon products differed significantly with respect to values age income and education based on these conclusions some policy implications are suggested

consumers willingness to pay for sustainable food products the case of organically and locally grown almonds in spain abstract organically and locally grown products have positive environmental impacts due to the reduction in the greenhouse emissions required for their production this paper contributes to this research stream by investigating consumers preferences and their willingness to pay for almonds that have different sustainable labels distance claims 100 km 800 km and 2000 km and the organic logo established by the european union to achieve the objective consumers participated in a non hypothetical choice experiment latent class modeling was employed to identify distinct patterns of valuation the results suggest that consumers were willing to pay a positive price premium for locally grown traveled the shortest distance and organically produced almonds whereas they were not willing to pay a price premium for almonds that have traveled longer distances moreover the findings show that consumer preferences for these claims were heterogeneous with three consumer segments identified as conventional consumers short distance consumers and sustainable consumers overall results confirm the results of previous studies because spanish consumers were willing to pay a premium price for those almonds that are organically and locally produced and therefore generate fewer greenhouse gases emissions the findings of this study added scientific value to scholars of sustainable consumer behavior because of the use of real choice experiment since no hypothetical evaluation method simulates real markets with real products and a transaction of money real choice experiment provides better approximations of true willingness to pay for organic and local almonds therefore real choice modeling eliminates hypothetical and social bias the results of this study contribute to insights in the promotion of sustainable consumption among citizens by policy makers in this regard promotional and educational campaigns could drive different segments of consumers to increase their knowledge on the benefits of reduction of the quantity of ghg emissions required for organic and locally grown production

modeling shifts in willingness to pay from a bayesian updating perspective this paper derives a structural shift empirical specification for a double bound dichotomous choice contingent valuation methodology premised upon willingness to pay wtp shifts ensuing from a representative model of respondent bayesian updating behavior we demonstrate by way of data simulations that a traditional structural shift specification may often fail at estimating true wtp in this context further simulations demonstrate that a simple extension of the traditional structural shift model derived explicitly from our bayesian framework can correct for much of the wtp bias with an empirical application confirming the simulation outcomes finally we investigate the relationship between strategic behavior and wtp shifts

estimating compensation payments for on farm conservation of agricultural biodiversity in developing countries article i nfo this paper examines the role of direct compensation payments for agrobiodiversity conservation using minor millet landraces in india as an example the cost of farmer participation in a hypothetical payments for agrobiodiversity conservation services pacs scheme is estimated using a stated preference valuation approach significant inter crop and inter varietal differences are observed with respect to consumption values upon which the compensation demanded by farm households is shown to primarily depend drawing on a categorisation of consumption values and farmer preferences the paper points to the importance of si multaneously considering a range of potential interventions in order to conserve a priority portfolio of agrobiodiverse resources in predominantly subsistence based agricultural systems

rules of thumb in games abstract a steady state random matching game model is proposed in which rules of thumb which assign strategies to individual games are the units of choice for individuals costs which reflect complexity or difficulty of use are associated with the rules independently of the games in which they are employed a population equilibrium is a distribution of rules across the population of players such that no individual has an incentive to change rules given the current distribution examples illustrate the concept and existence is demonstrated

consumers perceptions preferences and willingness to pay for wine with sustainability characteristics a review abstract the aim of this review article is to identify the state of the art and research gaps in consumer perceptions preferences and willingness to pay wtp towards wine with sustainability characteristics in an effort to cover all relevant literature we searched for scientific articles published between january 2000 and march 2016 the search resulted in 34 articles which were analysed in detail to assess the reviewed articles the alphabet theory which is a framework for explaining environmentally significant behaviour was used the review differentiates the results for consumers wine choice by the type of production method e g sustainable environmental friendly organic or local a considerable number of consumers across different countries had positive perceptions regarding these different production methods and reported a willingness to pay a premium for wine with characteristics of sustainable production however on average consumers awareness of the broad concept of sustainability regarding wine seemed low in some european countries and north america in particular organic and sustainability labels were often perceived as quality indicators in most cases the studies focused on the environmental aspects of sustainability environmental soundness was given most often as a determining factor in purchase decisions regarding wine with characteristics of sustainable production overall social and economic aspects were only just examined the results suggest that producing and marketing wine with sustainability characteristics is a promising strategy for quality differentiation particularly for wine that is both local and organic moreover marketers retailers and producers will likely profit from developing information campaigns with a focus on environmental as well as social and economic aspects to increase consumers knowledge of sustainable wine production thus creating preferences and influencing purchase behaviour gaining a deeper understanding of consumers attitudes and their buying motives regarding different sustainability attributes is recommended for future studies since none of the articles examined purchase behaviour in real market scenarios with real market transactions future research should focus for example on the analysis of household panel data as evidence of an attitude behaviour gap was found

dynamics of international integration of government securities markets abstract this paper investigates the dynamics of international government bond market integration in six of the g7 economies over two decades leading up to the global crisis it examines whether such integration had been significant the extent to which integration at the short and long end of the yield curve differed the nature of such integration and the extent of the decoupling of the long rates from short rates these issues are investigated using the rigorous smooth transition copula garch model framework the results show that integration at the long end of the yield curve had been increasing had become pronounced and was significantly greater than at the short end decoupling between the short and long end of the yield curve was notable with important implications for the efficacy of monetary policy in the period before the crisis

gains from trade and the sovereign bond market abstract increasing international flows of goods services and financial assets have been shown to increase a country s welfare through various channels this paper studies how a country s access to a bond market affects its welfare gains from international trade we do so by incorporating a sovereign bond market into a simple armington 1969 s trade model while standard trade models suggest surprisingly small gains from trade our model implies that introducing channels through a sovereign bond market greatly magnifies the gains from trade key mechanisms in the model are confirmed by data and the results are found to be robust to a variety of considerations

signaling character in electoral competition we study a one dimensional hotelling downs model of electoral competition with the following innovation a fraction of candidates have character and are exogenously committed to a campaign platform this is unobservable to voters character is desirable and a voter s utility is a convex combination of standard policy preferences and her assessment of a candidate s character this structure induces a signaling game between strategic candidates and voters since a policy platform affects voters utilities not only directly but also indirectly through inferences about a candidate s character the model generates a number of predictions starting with a failure of the median voter theorem jel d72 d82

the value of statistical life and the economics of landmine clearance in developing countries this paper presents estimates of the value of statistical life vsl in rural thailand using the contingent valuation cv method these estimates are applied to an economic analysis of landmine clearance the estimated vsl of us 250 000 suggests that the value of lives saved from landmine clearance is at least an order of magnitude greater than the values used in existing studies

contingent valuation of ecotourism in annapurna conservation area nepal implications for sustainable park finance and local development abstract to determine willingness to pay wtp for candidate entry fees contingent valuation surveys were administered to 315 foreign visitors to the annapurna conservation area nepal during april and may of 2006 the results of logit regression showed that the bid amount family size visitors satisfaction the use of a guide and group size were the most significant predictors of wtp results suggest that most visitors would be willing to pay an entry fee considerably higher than the current fee of 27 u s dollars usd the mean and median wtp were 69 2 and 74 3 usd respectively the most common explanation for wtp by respondents was a desire to better protect the environment the most common explanation for unwillingness to pay was that the bid was simply too expensive two models were developed based upon different predictions of visitor numbers an optimistic case and pessimistic case to calculate the expected revenue production and likely gross local economic impact of candidate entry fees based on this analysis we recommend an increase in the entry fee to usd 50 in the optimistic scenario this higher entry fee leaves a budget surplus in the pessimistic scenario it would reduce current budget deficits

individual expectations limited rationality and aggregate outcomes recent studies suggest that the type of strategic environment or expectation feedback can have a large impact on whether the market can learn the rational fundamental price we present an experiment where the fundamental price experiences large unexpected shocks markets with negative expectation feedback strategic substitutes quickly converge to the new fundamental while markets with positive expectation feedback strategic complements do not converge but show underreaction in the short run and overreaction in the long run a simple evolutionary selection model of individual learning explains these differences in aggregate outcomes

uncertain fiscal consolidations the paper explores the macroeconomic consequences of fiscal consolidations whose timing and composition are uncertain drawing on the evidence in alesina and ardagna 2010 we emphasize whether or not the fiscal consolidation is driven by tax rises or expenditure cuts we find that the composition of the fiscal consolidation its duration the monetary policy stance the level of government debt and expectations over the likelihood and composition of fiscal consolidations all matter in determining the extent to which a given consolidation is expansionary and or successful in stabilizing government debt

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

an assessment of greenhouse gas emissions and material flows caused by the finnish economy using the envimat model abstract an environmentally extended input output ee io analysis environmental impacts of material flows caused by the finnish economy was carried out in order to improve data on production and consumption in finland the study resulted in the envimat model which can be used to analyze the relationship between material flows environmental impacts and the economy the model is based on monetary and physical input output tables and an environmental life cycle impact assessment this article summarizes the main methodological aspects and findings regarding the material flows and climate impacts caused by the finnish economy in 2002 and 2005 the finnish model has relatively detailed input data with 150 industries and 918 products and the data on imports was assessed according to a mixed approach with the help of life cycle inventory data the results of the model showed that the finnish economy uses imported material resources as much as domestic resources life cycle greenhouse gas ghg emissions caused by imports were equivalent to 70 80 of domestic emissions the ghg emissions embodied in imports emissions abroad and exports emissions within finland were of the same magnitude the analysis showed that the service sector accounted for 44 of ghg emissions caused by the domestic final use of products analysis of the results also showed that the indicator of total material requirement tmr should not be used for environmental impact comparisons of products and services in the future the aim is to use the envimat model for assessing temporal changes in the economy for monitoring sustainable development for planning climate change mitigation and for identifying important factors in the economy and assessing their impacts

responders versus non responders a new perspective on heterogeneity this paper considers the implications of a particular type of heterogeneity one which characterizes a large number of economic environments but that has not received any systematic treatment in the literature the authors refer to this heterogeneity as responders versus nonresponders the paper begins by providing a general framework for the analysis of environments characterized by this heterogeneity and then shows how this framework can be used to help understand a wide variety of economic environments particular applications considered are near rationality network externalities and models of reputation copyright 1991 by royal economic society

rigidity of social systems the tendency for the members of a corporation or government to be resistant to change is explored in a model that encompasses two endemic features of such systems first the social system is modeled as a hierarchy and implicit within it is a selection process that determines who advances to higher levels second an agent s behavior is partially determined by imitating those who have risen in the ranks a behavioral norm of being rigid is found to be more prevalent and robust than one of being flexible a more volatile environment may also induce agents to be more resistant to change admirandi sed imitandi to be admired but not imitated st augustine

estimation of a hedonic price equation for bordeaux wine does quality matter in this paper the hedonic price technique is applied to bordeaux wine in the hedonic price function we include not only the objective characteristics appearing on the label of the bottle but also the sensory characteristics of the wine our data come from an experimental study in which juries have evaluated and graded a sample of bordeaux wines the estimation of the hedonic price equation shows that the market price is essentially determined by the objective characteristics the estimation of a jury grade equation shows that quality unlike the market price is essentially determined by the sensory characteristics

learning forecasting and optimizing an experimental study rational expectations re models have two crucial dimensions i agents on average correctly forecast future prices given all available information and ii given expectations agents solve optimization problems and these solutions in turn determine actual price realizations experimental tests of such models typically focus on only one of these two dimensions in this paper we consider both forecasting and optimization decisions in an experimental cobweb economy we report results from four main experimental treatments 1 subjects form forecasts only 2 subjects determine quantity only solve an optimization problem 3 they do both and 4 they are paired in teams and one member is assigned the forecasting role while the other is assigned the optimization task all treatments converge to rational expectation equilibrium ree but at different speeds we observe that performance is the best in treatment 1 and the worst in treatment 3 we further find that most subjects use adaptive rules to forecast prices given a price forecast subjects are less likely to make conditionally optimal production decisions in treatment 3 where the forecast is made by themselves than in treatment 4 where the forecast is made by the other member of their team which suggests that two heads are better than one in term of the speed of finding the ree

sovereign credit ratings in the european union a model based fiscal analysis abstract we present a model based measure of sovereign credit ratings derived solely from the fiscal position of a country a forecast of its future debt liabilities and its potential to use fiscal policy to repay these we use this measure to calculate credit ratings for 14 european countries over the period 1995 2012 this measure identifies a european sovereign debt crisis almost two years before the official ratings of the credit rating agencies

preferences and willingness to pay for gm labeling policies abstract the use of genetically modified organisms in agriculture is currently the focus of intense public and political debate press articles provide evidence that us consumer concerns toward biotechnology are increasing in this paper we analyze whether consumers prefer mandatory or voluntary labeling schemes through contingent valuation additionally we calculate the premium that consumers are willing to pay in order to subsidize their favorite labeling alternative we find that the premium associated with mandatory labeling is lower than expected costs this indicates that in spite of the concerns surrounding biotechnology consumers remain fairly confident with the current food and drug administration policy which does not require mandatory labeling
