consumer stated purchasing preferences and corporate social responsibility in the wood products industry a conjoint analysis in the u s and china the impacts of disclosed level of corporate social responsibility csr domestic versus imported origin and type of construction on consumers stated wood product purchasing preferences were examined in the u s and china hierarchical logit models based on a bayesian framework were utilized to test the magnitude and statistical significance of each wood product attribute using survey data results indicate that u s and chinese respondents a were more likely to choose products from manufacturing companies with a higher level of csr rating compared with an unknown one b preferred domestically manufactured wood products compared to imported ones and c expressed higher interest in wood products made of solid wood compared with composites in terms of demographics respondents higher education levels corresponded with higher preferences for products from companies with the highest five star csr rating in the u s statistically significant income effects were detected only in the chinese sample when respondents indicated their purchasing preferences for wood products with three star or five star csr levels implications for improving wood products companies managerial performance and suggestions for future studies are provided

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

multiproduct short run hospital cost functions empirical evidence and policy implications from cross section data economists and policymakers have been interested in hospital costs and the structure of hospital technologies for several decades now early interest was focused on the possibility of scale economies which implied increased efficiency for larger hospitals 6 8 12 13 18 20 while more recent interest has been stimulated by the inflationary spiral of hospital costs 1 15 17 22 as hospital costs have risen important policy questions concerning the impact on costs of the hospitals diagnostic case mix the hospitals admitting physicians the hospitals size and the hospitals efficiency have emerged and researchers have attempted to deal with these issues within the context of increasingly complex econometric models 1 2 5 24 27 however in attempting to analyze these important policy issues researchers have been forced to make two major types of compromises on the one hand appropriate data are often not available for estimating a well specified cost function e g information on admitting physicians and diagnostic case mix are often missing so that problems of specification error often plague the econometric results conversely in using imaginative ways to deal with data problems e g weighting in patient and out patient care to form a single index of hospital services 1 27 or estimating separate cost functions for each department in the hospital 2 researchers sometimes place unrealistic and unnecessary constraints on their econometric models the purpose of this study is to analyze the impact of several of the primary hospital characteristics mentioned above on the short run costs of hospitals within a theoretically consistent framework in the following discussion we also develop the theoretical

valuing option existence and bequest demands for wilderness to assess the relative importance of current costs and future benefits of nuclear waste storage we develop a simple model of bequest value the basic model of nonparternalistic altruism is extended to account for the uncertain nature of the externality

does no mean no a protest methodology in this paper we propose a method of identifying and truncating protesters in contingent valuation surveys we propose using a system of willingness to pay wtp questions that value multiple goods and that use both discrete choice and open ended questions coupled with multiple questions about protest beliefs administered to the entire sample protesters can then be identified because they reject all bids declare zero on all open ended questions and hold protest beliefs the proposed procedure has been empirically tested on an air pollution data set from poland where 27 of the sample was identified as protesters the adjustment for protesters increased the estimated wtp values by a factor of more than 3

spatial cost benefit thinking in multi functional forestry towards a framework for spatial targeting of policy interventions abstract many countries now actively encourage land use change for the provision of multiple benefits specifically including non market benefits often such policies have been poorly designed because of a lack of understanding of the spatial distribution of the potential costs and especially non market benefits from land use change as with market goods the potential yield of non market goods and services from land use can be highly spatially variable in recent years more and more studies on the economic aspects of natural resources have started to make use of geographical information systems gis what is yet lacking is the systematic adoption of a framework for the spatial targeting of policy interventions which can be used to improve decision making in terms of effectiveness efficiency equity or public acceptability this paper uses existing studies in forestry to present such a framework and discusses its potential uses and limitations as a new standard tool to inform multi functional land use decisions

rain and the democratic window of opportunity according to the economic approach to political transitions negative transitory economic shocks can give rise to a window of opportunity for democratic change we examine this hypothesis using yearly rainfall variation over the 1980 2004 period in 41 sub saharan african countries we find that a 25 drop in rainfall increases the probability of a transition to democracy during the following two years by around 3 percentage points a 5 fall in income due to low rainfall raises the probability of democratization by around 7 percentage points we also find that rainfall does not affect transitions from democracy to autocracy

testing for the survey mode effect on contingent valuation data quality a case study of web based versus in person interviews this paper addresses the lack of empirical evaluation of the use of web based surveys in the context of contingent valuation surveys we compare using a case study in person interviews with web based surveys regarding response rate information additivity effects and respondents attitudes towards paying the web based survey had a much lower response 5 1 than the in person interviewing 84 we find the web based contingent valuation surveys to be neither more susceptible to information additivity effects nor more prone to zero protest responses we conclude in favor of the use of web based surveys namely in portugal where the number of internet users is rapidly increasing although further research efforts are required on their use

the logic of political violence this paper offers a unified approach for studying political violence whether it emerges as repression or civil war we formulate a model where an incumbent or opposition can use violence to maintain or acquire power to study which political and economic factors drive one sided or two sided violence repression or civil war the model predicts a hierarchy of violence states from peace via repression to civil war and suggests a natural empirical approach exploiting only within country variation in the data we show that violence is associated with shocks that can affect wages and aid as in the theory these effects are only present where political institutions are non cohesive

the structure of costs and production in new zealand public hospitals and application of the transcendental logarithmic vaiable cost funcation new zealand s public hospitals provide free secondary health care to the public through taxation funding since these hospitals vary by both size and range of services provided the possibility of more porductive resource use is of explicit interest a translog variable cost function is estimated for new zealand public hospitals using 1987 cross section data an analysis of sthe function reveals the marginal costs short run and long run economies of scale and input factor substitution possibilities results suggest that a transfer of both patients with less severe conditions and staff from teachin hospitals to say country hospitals will result in a short run decareased total cost to the system the long run economies of scale estimates suggest that efficiency gains could result from downsizing large hospitals merging smaller hospitals and increasing patient turnover partial elasticites of demand indicate the asymmetric nature of factor substitution and the effect of specific inputs such as nurses

willingness to pay for e85 from corn switchgrass and wood residues abstract willingness to pay wtp for e85 automotive fuel blend of 85 ethanol and 15 gasoline was estimated from a contingent choice exercise contained in a national survey of consumers the choice exercise included e85 blends from three different feedstock sources corn grain switchgrass and wood wastes and an e10 blend 10 ethanol and 90 gasoline with corn grain as the ethanol feedstock results from the study indicate willingness to pay a premium for e85 from switchgrass compared with e10 from corn concerns about land use for food versus fuel had a negative impact on wtp for e85 from corn grain while greater concerns about fuel security relative to the environment had a positive impact

conjoint effect of environmental labeling disclosure of forest of origin and price on consumer preferences for wood products in the us and uk abstract a study that conjointly analyzed the effects of environmental labeling disclosure of forest of origin and price on consumer preferences for wood products was conducted in the us and the uk a choice based elicitation tool was used to mimic a real life situation where a single product was selected over a set of options data collected were analyzed using a conditional logit model certification issued by a government agency or an environmental non government organization both had a favorable effect on consumer preference over a non certified option the most relevant implication of our findings was the negative effect that disclosing information about a product coming from tropical forests had on consumer preferences even compared to a product of unknown origin a decline in product preference was observed along higher price premiums as expected the degree of sensitivity to price changes was affected by demographic characteristics model coefficients were used to estimate market shares of tropical wood products under different scenarios in both countries scenarios explored the effect of environmental certification and price premiums on product market shares

preservation or use a contingent valuation study of wilderness designation in utah evidence of strong opposition to wilderness proposals in utah suggested that the non market value of retaining those areas in multiple use management might be significant a contingent value analysis of both supporters and opponents of the two major proposals for wilderness designation in utah indicated that there existed significant non market willingness to pay on the part of opponents and that standard contingent valuation practice which does not explicitly consider these values could lead to a mis estimation of aggregate willingness to pay

estimation of distance decay functions to account for substitution and spatial heterogeneity in stated preference research in a site selection choice experiment various hypotheses are tested related to spatial heterogeneity in willingness to pay wtp for environmental improvements spatial heterogeneity is measured through distance decay effects substitute sites inside and outside the experiment s choice set and spatial trend variables we demonstrate that distance decay functions differ between users and nonusers and across study sites also the distance to substitutes outside the choice set explains spatial variation in wtp we show that further extending the model with spatial trend variables reveals additional spatial heterogeneity in choices accounting for spatial heterogeneity patterns results in significantly different wtp estimates for environmental improvements jel q25 q51

nonmarket values of major resources in the korean dmz areas a test of distance decay the demilitarised zone dmz and its adjoining areas serve not only as a geopolitical buffering zone between north and south korea but also as rare refuges for various animals and plants this paper investigates conservation values of major dmz resources and comparatively tests distance decay between contingent valuation and choice modelling the overall conservation value for the dmz resources per person as one off payments was 9 06 or 34 97 respectively from the cvm and cm datasets research findings deny distance decay regardless of elicitation methods when the distance variable is parameterised as part of utility functions conversely a segmentation valuation approach demonstrates conflicting conclusions on distance decay and the wtp anomaly between users and non users depending on elicitation methods the cm results demonstrate that protection of the dmz resources might be less important and attractive to local populations than to those in the distant regions a direct cross method transfer of any distance effect might not be granted

optimized quantity within distance models of spatial welfare heterogeneity abstract spatial welfare heterogeneity is frequently modeled within stated preference analysis as a function of discrete or continuous distance between households and affected resources a common example is distance decay analysis although distance based models such as these are easily estimated the ubiquity of this paradigm can lead to analyses that overlook other forms of analysis with equal or greater relevance this paper develops an alternative approach to spatial heterogeneity in stated preference willingness to pay wtp based on the quantity or area of an affected resource surrounding each respondent at an optimized distance band or radius with distance bands optimized using a grid search algorithm that maximizes model likelihood methods and results are illustrated using a choice experiment on riparian land restoration in maine usa the resulting quantity within distance model identifies systematic spatial patterns that are undetectable using distance based analysis and directly relevant for welfare analysis

valuing environmental commodities some recent experiments a general model of consumer behavior is proposed to assess six recent experiments that have attempted to reveal preferences for environmental goals each experiment used a mix of both the techniques and the theory of demand for non market commodities and each was designed to estimate a non market attitude associated with the environment and to analyze potential biases in the techniques the six cases show some consistency in results the linkage within the contingent market between the environmental attribute institutional setting and the bidding instrument must be realistic and accepted by the respondent to avoid biased results possibly the most important result is the replication of results using a traditional property value study and a contingent bidding approach all evidence obtained to date suggests that hedonic studies of property values or wages travel costs and survey techniques all yield values well one order of magnitude in accuracy 41 references 2 tables

the choice theory approach to market research this paper surveys economic choice theory stressing developments that permit use of data from psychometric and conjoint experiments to produce market demand forecasts alternatives to the widely used multinomial logit model are summarized and a new method for estimating multinomial probits is described an integration of choice models with attitudinal scaling and perceptual mapping within a latent variable system is described estimation of such systems under either random effects or fixed effects descriptions of heterogeneity across individuals is discussed issues in the use of choice models to describe responses from conjoint experiments are presented new regression diagnostic tests for the consistency of multinomial logit representations are discussed

plata o plomo bribe and punishment in a theory of political influence we present a model where groups attempt to influence policies using both bribes plata spanish for silver and the threat of punishment plomo spanish for lead we then use it to make predictions about the quality of a country s public officials and to understand the role of institutions granting politicians with immunity from legal prosecution the use of punishment lowers the returns from public office and reduces the incentives of high ability citizens to enter public life cheaper plomo and more resources subject to official discretion are associated with more frequent corruption and less able politicians this predicts that violence in a country will typically go together with corruption and worse politicians moreover the possibility of punishment changes the nature of the influence game so that even cheaper plata can lower the ability of public officials protecting officials from accusations of corruption immunity will decrease the frequency of corruption if the judiciary is weak and may increase the quality of politicians these predictions cannot emerge from a traditional model where only bribes are used the positive evils and dangers of the representative as of every other form of government may be reduced to two heads first general ignorance and incapacity or to speak more moderately insufficient mental qualifications in the controlling body secondly the danger of its being under the influence of interests not identical with the general welfare of the community

individualized geocoding in stated preference questionnaires implications for survey design and welfare estimation this paper evaluates the common practice of generic mapping in stated preference valuation in which identical policy area maps are shown to all respondents this is compared to a more information intensive alternative in which individualized maps identify the location of each respondent s home relative to policy effects the evaluation is grounded in a theoretical model clarifying the impact of individualized spatial information on preferences for non market outcomes the model is illustrated using an application of choice experiments to riparian restoration in coastal maine results characterize valuation contexts for which valid preference elicitation likely requires the provision of individualized spatial information

do political protests matter evidence from the tea party movement can protests cause political change or are they merely symptoms of underlying shifts in policy preferences this paper studies the effect of the tea party movement in the united states which rose to prominence through a series of rallies across the country on april 15 tax day 2009 to identify the causal effect of protests we use an instrumental variables approach that exploits variation in rainfall on the day of the coordinated rallies weather on tax day robustly predicts rally attendance and the subsequent local strength of the movement as measured by donations media coverage social networking activity and later events we show that larger rallies cause an increase in turnout in favor of the republicans in the 2010 congressional elections and increase the likelihood that incumbent democratic representatives retire incumbent policymaking is affected as well representatives respond to large protests in their district by voting more conservatively in congress finally the estimates imply significant multiplier effects for every protester republican votes increase by seven to fourteen votes together our results show that protests can build political movements that ultimately affect policy and they suggest that it is unlikely that these effects arise solely through the standard channel of private information revelation

modeling spatial patchiness and hot spots in stated preference willingness to pay stated preference analyses often impose strong assumptions regarding spatial welfare distributions that can influence the validity of welfare analysis and aggregation these include spatial homogeneity and continuous distance decay global assumptions such as these are increasingly questioned by non economics disciplines in favor of approaches that allow for local patchiness drawing from this literature this article proposes methods to identify and evaluate hot spots in stated preference welfare estimates using local indicators of spatial association methods are illustrated using geocoded choice experiment data addressing river restoration results suggest the presence of statistically significant non continuous patterns overlooked by current approaches

the environment as a luxury good or too poor to be green abstract this paper discusses the views of different authors on the relations between economic growth and environmental scarcities it lays out the common assumptions behind inglehart s postmaterialist thesis in environmental sociology krutilla s criterion for the valuation of environmental amenities hirsch s notion of the positional economy and pearce s numerical results on weak sustainability the paper shows how different views on the environmental consequences of economic growth imply at the same time different theories about environmental movements in rich countries there is an increasing demand for environmental amenities which cannot be substituted by products of the material economy and there are also environmental movements against the effluents of affluence in poor countries there are environmental movements characterized as the environmentalism of the poor

effect of distance on the preservation value of water quality in the past dozen years an extensive body of literature has developed on the willingness to pay for water quality in particular its recreation use and nonuse preservation values this paper illustrates a procedure for estimating the effect of distance on the preservation value of environmental quality using the contingent valuation approach the case considered is the potential degradation of water quality due to coal mining activity in the flathead river drainage system montana the analysis supports a negative association for this particular study area the effect of distance on preservation value was considered both directly and indirectly through its effect on visits 36 references 2 tables

exploring the drivers side of the blend wall u s consumer preferences for ethanol blend fuels abstract analysis of stated preferences from over 2300 u s respondents shows that general attitudes nationwide favor the use of ethanol as a motor fuel but a sizeable segment 20 indicated strong unwillingness to buy ethanol blend fuels results from a discrete choice experiment analyzed using mixed logit regressions show that all else constant price per gallon and miles per gallon dominated preferences for fuel attributes but ethanol content made the average consumer more likely to choose a blend fuel findings provide strong evidence of heterogeneity in preferences driven by attitudes but also affected by age and income at a point of price per mile equivalence for ethanol and gasoline in a market where gasoline e20 and e85 were available with no regulatory supply or technological constraints e85 would dominate market share in this case ethanol would account for 56 of volume of motor fuels consumed our results show a high level of consumer substitutability of gasoline with ethanol and willingness to choose high ethanol blend fuels which could help expand ethanol use beyond the current regulatory and technological limits of the blend wall

the effect of distance on willingness to pay values a case study of wetlands and salmon in california most contingent valuation studies in the literature utilized a pre determined geographic market area for their sample frame in other words they did not include variables that would measure the extent of the geographic areas over which to aggregate willingness to pay these studies implicitly assumed that the effects of geographic distance were moot an assumption that could have led to an understatement of the aggregate benefit values computed in these studies the overall goal of this study was to determine if distance affects willingness to pay for public goods with large non use values the data used came from a contingent valuation study regarding the san joaquin valley ca respondents were asked about their willingness to pay wtp for three proposed programs designed to reduce various environmental problems in the valley a logit model was used to examine the effects of geographic distance on respondents willingness to pay for each of the three programs results indicate that distance affected wtp for two of the three programs wetlands habitat and wildlife and the wildlife contamination control programs we calculate the underestimate in benefits if the geographic extent of the public good market is arbitrarily limited to one political jurisdiction

the aggregation of environmental benefit values welfare measures distance decay and total wtp abstract we review the literature regarding the aggregation of benefit value estimates for non market goods two case studies are presented through which we develop an approach to aggregation which applies the spatial analytic capabilities of a geographical information system to combine geo referenced physical census and survey data to estimate a spatially sensitive valuation function these case studies show that the common reliance upon political rather than economic jurisdictions and the use of sample mean values within the aggregation process are liable to lead to significant errors in resultant values we also highlight the fact that for resources with use values then we should expect overall values to reduce with increasing distance from such sites but that changes in the choice of welfare measure will determine whether such distance decay is to be expected within values stated by those who are presently non users the paper concludes by providing recommendations for future improvements to the methodology

characterizing the effects of valuation methodology in function based benefits transfer abstract meta analyses have demonstrated that willingness to pay wtp estimates vary systematically according to methodological factors the benefits transfer literature provides little guidance with regard to the treatment of such effects transfers are typically conducted by ignoring such effects using ad hoc adjustments or otherwise suppressing information regarding the sensitivity of wtp to methodological attributes this paper illustrates a means to characterize methodological effects within benefits transfer based on an application of the common bootstrap drawing from meta analysis the approach characterizes the sampling distribution of wtp with respect to patterns of methodological variation present in underlying studies results provide a means to characterize the extent of variation associated with predefined groups of methodological attributes providing transparent information on the sensitivity of wtp not typically available in benefits transfer

nimby or not exploring the relevance of location and the politics of voiced opinions in renewable energy siting controversies local protests against renewable energy facilities have added fuel to the debate about the so called nimby not in my back yard effect this paper identifies six variables that can hamper the comparison between different public perception studies and offers two broad conclusions on aggregate proximity does have strong influence on public attitudes to proposed projects but the nature strength and spatial scale of this effect may vary according to local context and value of the land residents of stigmatised places are more likely to welcome facilities that are relatively green while people who derive a more positive sense of identity from particular rural landscapes are likely to resist such potential developments especially if they also live there secondly the fear of being branded a nimby and the positive ethics associated with the notion of renewable are both likely to colour the responses of many interviewees these aspects need to be clarified and accounted for in analyses of elicited responses both quantitative and qualitative if we are to improve our understanding of the social construction of individual attitudes in siting conflicts

valuing non market wildlife commodities an evaluation and comparison of benefits and costs this paper compares the benefits and costs of nature conversation at three sites of special scientific interest benefits are estimated by contigent valuation expressed preferences and also the travel cost method revealed preferences oppurtunity costs are assessed from a financial cost viewpoint and also in terms of shadow prices or social costs results indicate that the valuation of wildlife and nature conservation largely depends upon the frame of reference adopted that social costs are considerably less than financial costs due to the effect of the common agricultural policy that user benefits are considerably less than financial costs and non user benefits must be included to cover even the social costs of nature conservation

can sustainable consumption be learned a model of cultural evolution abstract this paper shows how sustainable consumption patterns can spread within a population via processes of social learning even though a strong individual learning bias may favor environmentally harmful products we present a model depicting how the biased transmission of different behaviors via individual and social learning influences agents consumption behavior the underlying learning biases can be traced back to evolved cognitive dispositions challenging the vision of a permanent transition toward sustainability we argue that green consumption patterns are not self reinforcing and cannot be locked in permanently

organized crime and business subsidies where does the money go abstract business support policies are widespread in advanced countries to foster employment and productivity this paper analyses the role of organized crime in the allocation of public subsidies to businesses we assemble an innovative data set on the italian mafia at municipality level and test whether mafia ridden municipalities receive a disproportionally higher amount of funds we exploit exogenous variation at municipality level to instrument mafia activity and show that the presence of organized crime positively affects the probability of obtaining funding and the amount of public funds organized crime is also found to lead to episodes of corruption in the public administration sector a series of robustness checks confirms the above findings

exploring hospital production relationships with flexible functional forms this paper estimates a multiproduct variable cost function using data on a sample of california hospitals the results provide useful insights into the advantages and disadvantages of flexible functional forms for cost analysis the translog function appears to provide reasonable estimates of marginal costs when evaluated at or near the approximation point of the function the estimated function performs less satisfactorily however when evaluated outside this range the paper s results do not provide strong evidence of either ray scale economies or of weak cost complementarities there is some evidence however that the degree of scale economies may be underestimated

self rated economic welfare in russia abstract most of those russian adults who feel that they are poor are not classified as such in the poverty statistics and most of those who are classified as poor don t feel that way we study the determinants of peoples perceptions of their economic welfare in an unusually rich socioeconomic survey while income is a highly significant predictor subjective economic welfare is influenced by many other factors including health education employment assets relative income in the area of residence and expectations about future welfare insights are obtained into how objective data should be weighted in assessing economic welfare

consumer s willingness to pay more for municipal supplied water a case study abstract water supply in rural and urban settlements is an issue of prime concern especially in developing countries large financial inputs are being devoted to new projects and improvement of supply conditions in turn authorities have to look for sources of generating revenue to meet the expenditure and the one major source is the consumer this gives rise to an issue of consumers willingness to pay wtp for water supply service the present study aims at determining consumers wtp more for improvements and identifying the factors affecting wtp it was hypothesized that the satisfaction of consumers about water supply service their beliefs in the water management system and affordability might influence wtp more for water accordingly a sample study was planned in one of the mega cities in india the paper presents an approach to quantify the satisfaction level of consumers relating to water supply service and describes the impact of various factors on wtp through logistic regression analysis also the analysis of percentage increase in wtp is presented in the latter part of the paper

differentiating use and nonuse values for coastal pond water quality improvements this paper measures the benefits of water quality improvements in three coastal ponds on the island of martha s vineyard massachusetts u s a use option and existence values were elicited from martha s vineyard property owners by the contingent valuation method on average more than half of the total benefits are attributed to existence value results from the heckman selection model show that the exclusion of protest as well as missing bids does not cause significant bias in estimating respondents willingness to pay socioeconomic characteristics are found to have distinctively different influences on use option and existence values different model parameters are likely to be estimated depending on which value categories are measured by a selected valuation technique these findings emphasize the importance of nonuse values from water quality improvements and of socioeconomic characteristics for measuring different categories of values

norms and economic motivation in the swedish green electricity market abstract the purpose of this paper is to provide an econometric analysis of the most important determinants of swedish households choice to pay a price premium for green electricity we draw on recent developments in the literature on integrating norm motivated behavior into neoclassical consumer theory and assume that individuals have a preference for keeping a self image as a morally responsible person consumer behavior in the green market place will then be heavily determined by how purchases of different goods affect this self image the analysis is based on postal survey responses from 655 swedish households which are analyzed within a binary choice econometric framework the results indicate that the impact of choosing green on the household budget largely influences the choice between green and brown electricity as does the degree of perceived personal responsibility for the issue and the felt ability to affect the outcome in a positive way we find limited support for the notion that perceptions about others behavior in general affect individual moral norms and ultimately expressed behavior but this is also complemented by the influence of explicit social influence the difficulty in observing others purchases makes it however difficult to distinguish between social and moral norms in the case of green electricity

how large is the extent of the market for public goods evidence from a nationwide contingent valuation survey to assess the extent of the geographic area over which to sum vertically the public good benefits of removing two dams and restoring salmon populations households were surveyed throughout the us households were asked a dichotomouschoice contingent valuation question regarding their willingness to pay higher federal taxes for ten years to remove the dams and restore salmon populations while the distance from the site of the dam removal is statistically significant and negative in the logit willingness to pay equation benefits per household fall off slowly and the extent of the market is nationwide with a majority of households living outside the immediate area of the dam the rest of the us households reflect 97 of the national benefits for dam removal and salmon restoration this example suggests that failure to account for the national public good market can result in a serious underestimate of the value of public goods

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

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

political competition policy and growth theory and evidence from the us this paper develops a simple model to analyse how a lack of political competition may lead to policies that hinder economic growth we test the predictions of the model on panel data for the us states in these data we find robust evidence that lack of political competition in a state is associated with anti growth policies higher taxes lower capital spending and a reduced likelihood of using right to work laws we also document a strong link between low political competition and low income growth

what do we learn from the weather the new climate economy literature a rapidly growing body of research applies panel methods to examine how temperature precipitation and windstorms influence economic outcomes these studies focus on changes in weather realizations over time within a given spatial area and demonstrate impacts on agricultural output industrial output labor productivity energy demand health conflict and economic growth among other outcomes by harnessing exogenous variation over time within a given spatial unit these studies help credibly identify i the breadth of channels linking weather and the economy ii heterogeneous treatment effects across different types of locations and iii nonlinear effects of weather variables this paper reviews the new literature with two purposes first we summarize recent work providing a guide to its methodologies datasets and findings second we consider applications of the new literature including insights for the damage function within models that seek to assess the potential economic effects of future climate change jel c51 d72 o13 q51 q54

too poor to be green consumers a field experiment on revealed preferences for firewood in rural guatemala the paper reports on a field experiment that investigates whether households in guatemala are willing to surrender a small material gain in order to buy legal rather than illegal firewood given the ineffectiveness of command and control policies to curb the problem of illegal logging in guatemala the experiment assesses the potential viability of market oriented solutions local consumers in developing countries are generally believed to be too poor to pay a premium for green ethical products therefore little information has been gathered on willingness to pay wtp for such products and its determinants in non affluent consumer markets while our experiment on firewood consumption in central guatemala only implies a weak and indirect test of wtp for green products the results indicate that it is premature if not unwarranted to assume that the poor are not ready to make pro ethical choices in the marketplace moreover we find that information on the legal procedures for firewood extraction significantly affects consumer choice between legal and illegal firewood

organised crime institutions and political quality empirical evidence from italian municipalities this article assesses how legal institutions affect the influence of politically active criminal organisations on the human capital of elected politicians using data from over 1 500 southern italian municipalities in the period 1985 2011 it exploits municipal government dissolutions imposed by the national government for presumed mafia infiltration as a source of exogenous variation in the presence of politically active criminal organisations the results support theoretical predictions that the average education level of local politicians significantly increases when active mafia infiltration of local politics is remedied through the implementation of a stricter legal institutional framework

allocative inefficiency and its cost the case of spanish public hospitals in this paper we present a new empirical model based on an input distance function from which estimates of allocative inefficiency and its cost can be obtained the model avoids the greene problem which refers to the difficulty in practice of using a cost system to separate economic inefficiency into its technical and allocative components we also develop a procedure to calculate the cost of allocative inefficiency using a panel of spanish public hospitals to apply our methodology we find evidence of systematic allocative inefficiency in the employment of variable inputs since inputs are generally poor substitutes the cost of this allocative inefficiency is high

exploring welfare implications of resource equivalency analysis in natural resource damage assessments abstract resource equivalency analysis rea has become the dominant method for calculating natural resource damages for biological injuries from pollution incidents this methodology compares resources lost as a result of an incident to benefits that can be gained from a habitat or wildlife restoration project compensation is evaluated in terms of resource services instead of market currency recently this approach has been questioned regarding its ability to provide adequate compensation based on economic welfare principles the following paper examines these critiques and develops a model to quantify the welfare implications of using rea when some of its implicit assumptions are violated we focus on the situation where compensatory restoration projects provide services that are comparable to those lost as a result of an incident we examine simulation scenarios where the public has heterogeneous preferences for resources and where resource values change over time using the hicks kaldor criterion we find that the traditional rea provides an acceptable approximation of aggregate compensation for a reasonably wide range of economic and biological parameter combinations

green public procurement of certified wood spatial leverage effect and welfare implications certified and conventional products are not traditional substitute goods green public procurement stimulates certification globally but not in each region public procurement of the cheaper unsustainable product does not maximise welfare increasing the price premium for certified wood creates a trade barrier the high costs of forest certification exclude vulnerable producers

contingent valuation controversies and evidence contingent valuation cv has become one of the most widely used non market valuation techniques cv s prominence is due to its flexibility and ability to estimate total value including passive use value its use and the inclusion of passive use value in benefit cost analyses and environ mental litigation are the subject of a contentious debate this paper discusses key areas of the debate over cv and the validity of passive use value we conclude that many of the alleged problems with cv can be resolved by careful study design and implementation we further conclude that claims that empirical cv findings are theoretically inconsistent are not generally supported by the literature the debate over cv however has clarified several key issues related to nonmarket valuation and can provide useful guidance both to cv practitioners and the users of cv results

the monopoly of violence evidence from colombia many states in latin america africa and asia lack the monopoly of violence even though this was identified by max weber as the foundation of the state and thus the capacity to govern effectively in this paper we develop a new perspective on the establishment of the monopoly of violence we build a model to explain the incentive of central states to eliminate nonstate armed actors paramilitaries in a democracy the model is premised on the idea that paramilitaries may choose to and can influence elections since paramilitaries have preferences over policies this reduces the incentives of the politicians they favor to eliminate them we then investigate these ideas using data from colombia between 1991 and 2006 we first present regression and case study evidence supporting our postulate that paramilitary groups can have significant effects on elections for the legislature and the executive next we show that the evidence is also broadly consistent with the implication of the model that paramilitaries tend to persist to the extent that they deliver votes to candidates for the executive whose preferences are close to theirs and that this effect is larger in areas where the presidential candidate would have otherwise not done as well finally we use roll call votes to illustrate a possible quid pro quo between the executive and paramilitaries in colombia language en

the economic benefits of reducing the environmental effects of landfills heterogeneous distance decay effects this paper estimates the economic benefits of different alternative policies considered for reducing the external effects caused by the utilization of landfills in solid waste management the preferences of the local population in the surrounding areas of a landfill are evaluated utilizing a discrete choice experiment in which subjects are presented with alternative policy decisions that involve reducing the material processed through the landfill various models were employed in order to capture heterogeneous preferences resulting in a mixture of normals modelling approach mn mnl outperforming other alternative models of heterogeneity the results show that the policy of moving the landfill away from the population does not provide the most benefits when compared to a policy of increasing recycling in the household the economic benefits of the waste management policies are heterogeneous across the population surrounding the landfill and so the distance decay functions thus the economic benefits for most waste management policies can increase or decrease the further away the subject lives from the landfill depending on the preferences of his her segment and the type of policy employed

trafficking networks and the mexican drug war abstract drug trade related violence has escalated dramatically in mexico since 2007 and recent years have also witnessed large scale efforts to combat trafficking spearheaded by mexico s conservative pan party this study examines the direct and spillover effects of mexican policy toward the drug trade regression discontinuity estimates show that drug related violence increases substantially after close elections of pan mayors empirical evidence suggests that the violence reflects rival traffickers attempts to usurp territories after crackdowns have weakened incumbent criminals moreover the study uses a network model of trafficking routes to show that pan victories divert drug traffic increasing violence along alternative drug routes jel d72 d85 k42 o17 z13

directional heterogeneity in wtp models for environmental valuation many studies in the stated preference literature on environmental valuation do not include the effects of substitutes and distance in willingness to pay wtp models in spite of the relevance of these effects in aggregation and benefit transfer heterogeneity in the availability of substitutes over space may cause multidirectional distance effects in wtp as a result disregarding this spatial heterogeneity may lead to biased estimators of the distance effect and associated wtp values cameron 2006 in this paper we demonstrate that distance decay is subject to significant directional effects which tend to be related to differences in the availability of substitutes across the study area we apply a straightforward methodology to account for such spatial heterogeneity in choice experiments and assess the effect on wtp for improvements in ecosystem services in a lake district we model distance decay effects whilst controlling for heterogeneity between users and non users and non use related wtp reasons the directional effects result in significantly different wtp estimates different market sizes reflecting the population with positive wtp and differences in total wtp up to 32

nonparametric analysis of returns to scale in the us hospital industry this paper presents new estimates of scale economies for us hospitals we show that the common translog specification of hospital costs is a misspecification and employ nonparametric local linear estimation with both continuous and discrete covariates a bootstrap method is used to provide inferences regarding ray scale economies and expansion path scale economies for a large sample of hospitals covering 1984 1996 we find evidence of changes in the structure of hospital costs over the sample period as well as evidence of locally optimal hospital sizes copyright 2004 john wiley sons ltd

difference in preferences or multiple preference orderings comparing choices of environmental bureaucrats recreational anglers and the public abstract do environmental protection agency epa bureaucrats represent the general public or are they more in line with an interest group we study preferences for environmental policy using a choice experiment ce on three populations the general public swedish epa bureaucrats and recreational anglers we also test for existence of multiple preference orderings half of the respondents were asked to choose the alternatives that best corresponded with their opinion and the other half was asked to take the role of a policy maker and make recommendations for environmental policy the sepa bureaucrats have the highest marginal willingness to pay mwtp to improve environmental quality differences in mwtp are robust and not due to differences in socio economic characteristics across the populations we only found weak evidence of multiple preference orderings

the spatial extent of water quality benefits in urban housing markets water quality regulation continues to be controversial as demonstrated by recent litigation between the u s environmental protection agency and the state of florida over nutrient standards while the costs of standards are usually known benefits may be diverse and difficult to identify this study investigates the effects of enhanced water quality on both waterfront and nonwaterfront property prices using hedonic models within an urban market findings indicate 1 the value of increased water quality depends upon the property s location and proximity to waterfront and the surface area of the water body and 2 aggregate benefits to nonwaterfront homes may dominate those realized by waterfront homeowners

effect of experimental design on choice based conjoint valuation estimates in this article we investigate the effect of several commonly used experimental designs on willingness to pay in a monte carlo environment where true utility parameters are known all experimental designs considered in this study generated unbiased valuation estimates however random designs or designs that explicitly incorporated attribute interactions generated more precise valuation estimates than main effects only designs a key result of our analysis is that a large sample size can substitute for a poor experimental design overall our results indicate that certain steps can be taken to achieve a manageably sized experimental design without sacrificing the credibility of welfare estimates

reformulating the foundations of consumer choice theory and environmental valuation abstract the burgeoning field of environmental valuation has raised serious doubts about the fundamental axioms of consumer choice theory the general validity of the walrasian system and methodological individualism this paper examines these aspects of consumer choice theory paying particular attention to the pioneering contributions of georgescu roegen we argue that evidence from psychology game theory anthropology and contingent valuation surveys reveals a more complex pattern of decision making than that described by neoclassical utility theory we discuss the notions of the invariance of preferences non satiation the principle of complementarity lexicographic preferences and the hierarchy of wants with reference to environmental valuation we also discuss the notion of marginal utility of money the validity of the walrasian system and methodological individualism using scaling concept in hierarchy theory we then address the conflict between theory and reality by introducing a probabilistic binary choice scheme under uncertainty about environmental attributes we argue that these extensions are necessary to account for consumer choices revealed in environmental valuation surveys we conclude with the hope that a reformulation of consumer choice theory based on realistic models of human behavior can be the basis for a viable alternative to neoclassical welfare economics

specification bias in contingent valuation from omission of relative price variables the specification bias from omission of relative price variables in contingent valuation functions is investigated omitted variable bias will cause the determinants of willingness to pay wtp to assume zero the omission of relative price variables constitute policy implications forecast values of wtp values will be biased when empirical wtp functions are used the effects of relative prices in empirical valuation functions should be included in future studies of contingent valuation

valuing a fishing day an application of a systematic varying parameter model deciding how to allocate forage among animals is a fundamentally important process in range management the wisdom of these decisions can be enhanced by estimating the marginal value of forage needed by competing species we present a method for

omitted variable bias and hospital costs this research examines the impact of omitted variables on the accuracy of parametric hospital cost function estimations based on quebec hospital level data we assess the effect of omitted variables resulting from incomplete data on technology and performance measurement and on tests of the cost minimizing behavior of the institution our results show that important characteristics of hospital technology such as returns to scale are extremely sensitive to omitted variable bias similarly estimates of hospital performance are poor indicators of actual performance when data are incomplete

poor institutions rich mines resource curse in the origins of the sicilian mafia with weak law enforcement institutions a positive shock to the value of natural resources may increase demand for private protection and opportunities for rent appropriation through extortion favouring the emergence of mafia type organisations we test this hypothesis by investigating the emergence of the mafia in twentieth century sicily where a severe lack of state property rights enforcement coincided with a steep rise in international demand for sulphur sicily s most valuable export commodity using historical data on the early incidence of mafia activity and on the distribution of sulphur reserves we document that the mafia was more present in municipalities with greater sulphur availability

choice modelling and its potential application to tropical rainforest preservation abstract loss of rainforest occurs in part because of a global market failure problem markets routinely transmit signals about international demands for forest products such as timber but fail to transmit signals about demands for preservation to make efficient resource allocation choices decision makers need some framework to estimate the non use values that might be held by an international community for rainforest preservation non market valuation techniques can be used for this purpose but framing and other problems limit the application of the contingent valuation method cvm an alternative technique choice modelling cm appears to hold some promise because it can be used to model complex situations and to frame choices consistent with real life choices in this paper a cm experiment to assess the values that australians hold for rainforest conservation in vanuatu is reported the experiment disguises effectively the issue of interest rainforest conservation in vanuatu within a pool of other conservation locations also the experiment demonstrates that choice tradeoffs may involve a variety of environmental and socio economic factors rather than be concentrated on some monetary tradeoff the results demonstrate that a variety of predictive and valuation tools can be gained from a cm experiment and suggest that further development is warranted

a comparative application of data envelopment analysis and translog methods an illustrative study of hospital production this paper compares inferences about hospital cost and production correspondences from two different estimation models 1 the econometric modeling of the translog cost function and 2 the application of data envelopment analysis dea while there are numerous examples of the application of each approach to empirical data this paper provides insights into the relative strengths of the estimation methods by applying both models to the same data the translog results suggest that constant reruns are operant whereas the dea results suggest that both increasing and decreasing returns to scale may be observed in different segments of the production correspondence in turn suggesting that the translog model may be averaging diametrically opposite behavior on the other hand by examining the rate of output transformation both models agree that patient days devoted to care of children are more resource intensive than those devoted to adults or to the elderly in addition we compare estimates of technical efficiencies of individual hospitals obtained from the two methods the dea estimates are found to be highly related to the capacity utilization but no such relationship was found for the translog estimates this comparative application of different estimation models to the same data to obtain inferences about the nature of underlying cost and production correspondences sheds interesting light on the strengths of each approach and suggests the need for additional research comparing estimation models using real as well as simulated data

weak states causes and consequences of the sicilian mafia we document that the spread of the mafia in sicily at the end of the 19th century was in part caused by the rise of socialist peasant fasci organizations in an environment with weak state presence this socialist threat triggered landowners estate managers and local politicians to turn to the mafia to resist and combat peasant demands we show that the location of the peasant fasci is significantly affected by a severe drought in 1893 and using information on rainfall we estimate the impact of the peasant fasci on the location of the mafia in 1900 we provide extensive evidence that rainfall before and after this critical period has no effect on the spread of the mafia or various economic and political outcomes in the second part of the article we use this source of variation in the strength of the mafia in 1900 to estimate its medium term and long term effects we find significant and quantitatively large negative impacts of the mafia on literacy and various public goods in the 1910s and 20s we also show a sizable impact of the mafia on political competition which could be one of the channels via which it affected local economic outcomes we document negative effects of the mafia on longer term outcomes in the 1960s 70s and 80s as well but these are in general weaker and often only marginally significant one exception is its persistent and strong impact on political competition

payment source and the cost of hospital care evidence from a multiproduct cost function with multiple payers abstract this study investigates the capacity of hospitals to vary the intensity of their services based on patients expected sources of payment while the concept of price discrimination by hospitals based on payer generosity cost shifting has been discussed extensively the notion that hospitals can adjust payer specific marginal costs to reflect differences in reimbursement policies has not been studied in depth to examine this issue this analysis employs a multiproduct cost function with hospital outputs defined as admissions by payment source controlling for the distribution and severity of illness casemix for each payer marginal costs of casemix adjusted discharges are obtained and compared for medicare medicaid private payers and a residual category that includes uncompensated care we find that indeed payer specific marginal costs generally reflect payer generosity

a two stage translog marginal cost pricing approach for floridian hospital outputs since the passage of the affordable care act aca of 2010 issues still remain regarding the mandated purchase of insurance to ensure more universal coverage one such issue is the pricing of these insurance packages and whether or not the reimbursements will cover necessary services therefore policy concerns exist that increasing the number of insured individuals may not curtail costs conversely providers may not wish to treat patients covered by excessively frugal plans such as medicaid hence the trade offs between access and cost control in this article we present findings from a cost function and a productivity approach to determine the marginal cost of providing inpatient hospital care for hospitals operating in florida during 2005 using these methodological approaches we are able to use the marginal rate of transformation to determine the relative marginal costs while controlling for hospital technical and allocative inefficiency our work differs from earlier articles as we avoid the greene problem for cross sectional models through a two step approach by including both reimbursement rates under conditions of hospital efficiency we can ascertain payment schemes that should at least in theory cover necessary costs for patient care without leading to excessive input usage

under the weather health schooling and economic consequences of early life rainfall life in rural areas of developing countries is prone to many kinds of risk such as illness or mortality of household members crop or other income loss due to natural phenomena weather insect infestations or fire for example and civil conflict in addition to their contemporaneous effects the effects of certain types of shocks may still be felt many years or even decades later from a public policy standpoint it is particularly important to identify shocks that have large long run effects moreover the mechanics underlying the persistence of shocks may be of con siderable interest for example a health shock may have a long run effect simply because the health shock itself persists over time alternately the health shock may not directly affect long run outcomes but it could affect some other outcome such as educational attainment that helps determine long run well being in this paper we focus on shocks that occur at the very beginning of life we ask how sensi tive long run individual well being is to environmental conditions around the time of birth in particular we examine the effect of weather shocks around the time of birth on the adult health education and socioeconomic outcomes of indonesian women and men born between 1953 and 1974 in addition we attempt to shed light on the intervening pathways connecting early life rainfall to adult outcomes illuminating the roles of health and educational attainment in deter mining adult socioeconomic status this investigation has considerable data requirements it necessitates information on weather shocks experienced by individuals several decades earlier as well as detailed current informa tion on adult outcomes we use information in the indonesian family life surveys ifls on an individual s year and location of birth and link each individual in that survey to locality specific rainfall data for their birth year for individuals born in rural areas on whom we focus rainfall variation across space and time should generate corresponding variation in agricultural output and thus household income to deal with measurement error in the rainfall data we run instrumental variables regressions where variables for rainfall measured at slightly more distant rainfall stations serve as instruments for rainfall in the individual s birthplace and birth year we examine the impact of early life rainfall on a range of adult outcomes observed in 2000 we find that higher early life rainfall leads to improved health schooling and socioeconomic status for women women with 20 percent higher rainfall relative to normal local rainfall in their year and location of birth are 3 8 percentage points less likely to self report poor or very poor health they attain 0 57 centimeters greater height attain 0 22 more completed grades of

validation of stated preferences for public goods a comparison of contingent valuation survey response and voting behaviour this study reports the results from an in person comparison of contingent valuation cv survey response and subsequent voting behaviour on comparable propositions to increase public spending for landscape protection a substantial proportion of cv responses were not consistent with self reported actual voting decisions suggesting an upward bias of stated willingness to pay item non response and protest zero bids were more frequently given by those rejecting than those approving the actual proposition self reported actual decisions yielded a more consistent explanatory pattern than did hypothetical choices the official aggregate voting records show that these results cannot be explained simply by errors in self reported votes we conclude that referenda provide a valuable opportunity to test stated preference methods for public goods particularly public goods with significant passive use values however an important requirement is that the stated choices to be compared with the referendum decisions unlike in previous studies come from independent contingent valuation surveys
