altruistic egoistic and biospheric values in willingness to pay wtp for wildlife abstract we attempt to measure general attitudes and ethical beliefs towards preservation as well as the importance of each of the three considered value orientations biospheric egoistic and altruistic in wtp estimates in the present study we apply the gac scale to a contingent valuation exercise for the recovery of the common murre uria aalge in galicia spain up to now only a few studies in the field of environmental and ecological economics have analyzed value orientations under the environmental concern ec framework obtaining mixed results in the present work we conclude that ethical aspects affect the individuals decision making process and that value orientations play an important role in the pro environmental attitude formation these value orientations affect willingness to pay wtp estimates for environmental goods

the limits of market oriented regulatory techniques the case of automotive fuel economy the search for more efficient market oriented regulatory techniques has produced significant recent advances in several areas among these would appear to be the corporate average fuel economy cafe approach to reducing gasoline consumption by the domestic automobile fleet the 1975 energy policy and conservation act required manufacturers to sell fleets with a sales weighted average of 18 miles per gallon in the 1978 model year 19 mpg in 1979 20 mpg in 1980 and 27 5 mpg in 1985 1 the standards for the four intervening years were subsequently set by the national highway traffic safety administration at 22 24 26 and 27 miles per gallon the advantages of the averaging approach over uniform vehicle standards or a gas guzzler tax are two fold first cafe permits each firm to increase its overall fuel efficiency in the cheapest manner since the costs of mileage improvements for different vehicles may be rather different 2 and second it permits the continuation of a diverse product mix to the consumer since a uniform standard would probably result in the demise of certain models these arguments for averaging are now so widely accepted that the principle is being proposed inter alia for automotive emissions standards as well that is instead of maximum allowable emissions for each and every model manufacturers could produce models with various levels of pollutants

entrepreneurial human capital and the long run survival of firms in india abstract this paper analyses the characteristics of entrepreneurs that contribute to firms survival in less developed countries ldcs the study which relies on data collected in a 1971 survey of entrepreneurs in south india and a follow up survey of surviving firms in 1993 finds that entrepreneurial human capital greatly influences firm survival the results indicate that firms founded by older entrepreneurs in higher castes are most likely to survive but that increased education of the founding entrepreneur reduces survival these results provide evidence that opportunities of entrepreneurs outside the firm ignored in most theories are important in firm survival

a joint investigation of public support and public values case of instream flows in new mexico abstract instream flow can be defined as the flow of water in its natural channels without diversion alone among the western us states new mexico nm fails to provide any mechanism for the protection of instream flows and has a long history of political resistance to any change in the status quo using the combined results from two statewide telephone surveys this study jointly investigates stated voting preferences for a proposed institutional change and stated valuation preferences for minimum instream flow protection the contingent valuation cv question uses a dichotomous choice dc elicitation format and a voluntary contribution trust fund payment vehicle results show a highly significant positive correlation between expressed voting preferences and expressed valuation preferences additionally those individuals who respond yes to the voting question have an expected willingness to pay wtp of 80 with a 95 confidence interval ci that is always positive 62 97 while those who respond no to the voting question have an expected wtp that is actually slightly negative 6 with a 95 ci containing zero 14 2 taken together these results provide evidence of construct validity estimation results are also shown to be temporally reliable across repeated samples thus there is strong evidence of public support for instream flow protection and its associated nonmarket benefits such evidence helps to provide instream flow concerns with standing in future nm water policy debates prominent examples include explicitly defining beneficial use and public welfare to allow consideration of instream flow protection

is the stock market sticker shocked a study of market response to recent cafe regulations in the us in response to increasing environmental concerns to improve energy security and to conserve energy use the us government has proposed a new round of corporate average fuel economy cafe standards many studies have focused on how the cafe standard can be met by various automakers that have sales in the us market and the costs and benefits of the companies meeting the standard however the stock markets view on the impact of the standard on automakers profitability is largely absent we study the more recent episode of the cafe regulation in an effort to try to detect the market response using the standard event study method our empirical findings suggest that while the stock market had some responses to the regulation the large scale and systematic reaction to the regulation is absent in addition the market response pattern to the regulation appears to be tied to the individual company s compliance condition if there is any significant response at all

consumer response to commodity specific and broad based promotion programs for fruits and vegetables generic promotion activities have traditionally been used for individual agricultural commodities yet there is renewed interest in implementing a mandatory broad based promotion program for all fruits and vegetables here we use data from an experiment that introduce subjects to various promotional efforts for fruits and vegetables to estimate the shift and rotational effects of advertising econometric results indicate that commodity specific promotional efforts may not be effective at increasing demand for fruits and vegetables after controlling for various demographic differences among treatments our results show that consumers valuation of fruits and vegetables was highest among subjects exposed to broad based advertisements copyright 2011 oxford university press

advertising and the us market demand for beer the us per capita market demand for beer is empirically estimated to determine the effect of advertising on the demand for beer the empirical results indicate that the most important determinants of demand are the price of beer the price of substitutes demographic factors and a light beer dummy variable the positive effects of income and lagged consumption appear to be small although many have argued that advertising promotes beer consumption the empirical results of this study do not support this hypothesis

sustainability as opportunity this paper explores the relationship between sustainability concepts and contractarian principles of distributional fairness a commitment to equality of opportunity between contemporaries entails that life opportunities should be nondiminishing from generation to generation defining sustainability as nondeclining utility is analytically suggestive but practically problematic given the uncertainties that surround future preferences and technologies life opportunities may be sustained however by providing future generations with specific endowments of reproduced capital technological capacity natural resources and environmental quality in this setting capital resource substitutions are defensible only if there is compelling evidence that they would benefit both present and future generations

does consumer irrationality trump consumer sovereignty scholars working on the border of economics and psychology have documented many contexts in which individual decision making is unreliable and might be improved by paternalistic interventions against this mounting body of negative evidence economists default belief in consumer sovereignty has been motivated primarily by theory rather than evidence the goal of the present study is to see whether there is direct evidence supporting economists faith in consumer sovereignty in a simple context we address this question by presenting direct evidence that consumers own purchases generate between 10 and 18 more value per dollar spent than items received as gifts

measuring market integration foreign exchange arbitrage and the gold standard 1879 1913 a major question in the literature on the classical gold standard concerns the efficiency of international arbitrage authors have examined efficiency by looking at the spread of the gold points gold point violations or the flow of gold or by tests of various asset market criteria including speculative efficiency and interest arbitrage these studies have suffered from many limitations both methodological and empirical we offer a new methodology for measuring market integration based on nonlinear theoretical models and threshold autoregressions we also compile a new high frequency series of continuous daily data from 1879 to 1913 we can derive reasonable econometric estimates of the implied gold points and price dynamics the changes in these measures over time provide an insight into the evolution of market integration

the evolution of hyperbolic discounting implications for truly social valuation of the future abstract we explore the standard expected utility model and alternatives to it we then examine the behavioral and neurological evidence for hyperbolic discounting we discuss evidence related to the neurological and behavioral evolution of discounting in non human animals and in humans we explore new findings about the importance of sociality in human behavior and the implications for truly social time preference finally we discuss the implications of the neurological evidence on discounting for social environmental valuation in particular the implications for very long run decisions such as those involved in climate change mitigation and biodiversity preservation

searching for the correct benefit estimate empirical evidence for an alternative perspective this paper contrasts the results of the contingent valuation hedonic price and property damages avoided valuation techniques each technique was used to estimate the value of flood risk reduction from the construction of a flood control project voting behavior in a referendum called specifically for the provision of the project was used to further interpret the results from the three valuation studies substantial differences were found between the estimates in explaining these differences an alternative perspective on the current debate over the validity and accuracy of nonmarket value estimates is offered

religious participation and children s education a social capital approach abstract based on the argument in both economic and sociological literature that religion is conducive to children s human capital formation this paper provides a model of religious participation and explores a mechanism that social capital affects children s education a la coleman coleman j s 1988 social capital in the creation of human capital american journal of sociology 94 s95 s120 the model generates several interesting implications which help explain some important stylized facts about education and religion further in a dynamic setting the model shows that there exists a steady state in which individuals allocate a positive amount of time and resources to religious activities thus it complements the existing literature to explain why seemingly unproductive religions can be everlasting

stigler becker versus myers briggs why preference based explanations are scientifically meaningful and empirically important abstract economists typically object to preference based explanations of human behavior differences in preferences explain everything and therefore nothing but this argument is only correct assuming that no empirical evidence exists to discipline preference based explanations in fact over the past decade personality psychologists have produced a robust collection of stylized facts about human preferences while preferences are empirically quite stable they are far from identical and have proven predictive power for economically interesting variables the empirical challenge for future research is to jointly estimate the impact of preferences and constraints to obtain unbiased measures of their relative importance

a complex systems approach to the value of ecological resources a theory of value sits at the core of every school of economic thought and directs the allocation of resources to competing uses ecological resources complicate the modem neoclassical approach to determining value due to their complex nature considerable non market values and the difficulty in assigning property rights application of the market model through economic valuation only provides analytical solutions based on virtual markets and neither the demand nor supply side techniques of valuation can adequately consider the complex set of biophysical and ecological relations that lead to the provision of ecosystem goods and services this paper sets out a conceptual framework for a complex systems approach to the value of ecological resources this approach is based on there being both an intrinsic quality of ecological resources and a subjective evaluation by the consumer both elements are necessary for economic value this conceptual framework points the way towards a theory of value that incorporates both elements so has implications for principles by which ecological resources can be allocated c 2005 elsevier b v all rights reserved

policy watch government analysis of the benefits and costs of regulation recently congress has shown a greater interest in assessing the economic impact of regulation this interest was driven in part by estimates that federal regulation costs several hundred billion dollars annually in 1996 congress required the director of the office of management and budget to provide estimates of the total annual benefits and costs of individual regulations this essay reviews the increasing use of economic analysis in regulatory decisionmaking critically assesses the first 0mb report and considers how the use of economic analysis can help inform regulatory decisionmaking it argues that policymakers need to address a growing body of evidence that casts doubt on the effectiveness and efficiency of much regulation

gasoline taxes or efficiency standards a heterogeneous household demand analysis abstract using detailed consumer expenditure survey data and a flexible semiparametric dynamic demand model this paper estimates the price elasticity and fuel efficiency elasticity of gasoline demand at the household level the goal is to assess the effectiveness of gasoline taxes and vehicle fuel efficiency standards on fuel consumption the results reveal substantial interaction between vehicle fuel efficiency and the price elasticity of gasoline demand the improvement of vehicle fuel efficiency leads to lower price elasticity and weakens consumers sensitivity to gasoline price changes the offsetting effect also differs across households due to demographic heterogeneity these findings imply that when gasoline taxes are in place tightening efficiency standards will partially offset the strength of taxes on reducing fuel consumption

rational behavior and economic theory abstract nowadays it seems almost universally presumed that the fundamental characteristic of homo oeconomicus is his rationality we analyze the role played by the concept of rationality in economic theory and demonstrate that it is necessarily constrained to be an essentially contentless notion we show that the main body of economic theory is firmly grounded and that some contrasting approaches to rationality although leading to heated debates and vivid confusion have no fundamental significance for economics with a refereshed view on the essence of economics we argue that the principles of economic theory form an essential methodological guide for the emergent line of research based on the use of so called evolutive models

coordination and contagion individual connections and peer mechanisms in a randomized field experiment abstract this paper investigates peer effects at the level of individual connections leveraging the approach to shed light on peer mechanisms in a field experiment using college freshmen we elicited best friends and offered monetary incentives for gym visits to a treated subset we find large spillovers from treated subjects to treated best friends but none from treated subjects to control best friends we also find evidence of a mechanism subjects coordinate by visiting the gym with best friends indicating that the intervention harnesses complementarities in utility or commitment mechanisms results highlight subtle peer effects and mechanisms that often go undetected

entrepreneurship social mobility and income redistribution in south india development economists have been preoccupied with the problem of increasing the size of the gnp pie to the relative neglect of its distribution despite the recent disenchantment with the viewpoint that all classes share in the benefits of industrial growth empirical data on the distribution of income business opportunity and economic power are in short supply many of the studies on entrepreneurship and economic development when they are not apologetics for ruthless capitalist exploitation as paul baran suggests extol the achievements of the capitalist entrepreneur without examining class origins and monopoly advantage joseph schumpeter sees entrepreneurs irrespective of class origin as heroic figures with the dream and will to found a private kingdom to conquer adversity to achieve success for its own sake and to experience the joy of creation for gustav papanek 1967 the private entrepreneur who is frugal diligent far sighted remarkably able and willing to take political risks is in large part responsible for the success of pakistan in achieving rapid industrialization

international passenger transport and climate change a sector analysis in car demand and associated co2 emissions from 2000 to 2050 abstract the paper provides global regionalized projections of passenger car demand use and associated co 2 emissions from 11 world regions the study is based on empirical data that have been originally collated from international sources for the purpose of modeling region specific car stock demand derived demands serve as indicator of car related fuel consumption and associated co 2 emissions which are calculated on the basis of behavioral and technological scenarios the obtained co 2 emission paths are sectoral baseline scenarios that identify region specific potentials of growth in car induced co 2 emissions assuming that current trends continue to prevail the study adopts a multi model approach to car demand by applying two methodologies rooted in the economics of consumption utility maximization and single equation models the utility maximization method for modeling car demand is driven by the preferences of the representative consumers of each world region subject to exogenous price and income trajectories the latter is adopted from an optimal growth model this is a novel approach to projecting global regionalized sectoral car demands the study is complemented by the application of single equation income consumption models based on logistical gompertz functions and non linear regression techniques to compare model results

short run fuel price responses at the pump and on the road abstract we provide evidence that motorists respond to short run fluctuations in fuel prices at the gas pump and not on the road employing variants of censored panel regression to control for censoring of the dependent variable we find that the fuel price has a negative impact on the quantity of fuel purchased but no consistently significant impact on the subsequent distance driven until the next refill over the short run drivers thus appear to cope with high fuel prices by adjusting fuel purchases with each visit to the filling station but without altering their daily mileage

a common features analysis of amsterdam and london financial markets during the eighteenth century we examine the financial linkage between the london and amsterdam financial markets using stock prices recorded in each market over the period 1723 94 in conjunction with tests for common trends cycles and regime shifts these tests reveal a surprising degree of integration between the markets as their prices move together in both the short and long run moreover shocks to the assets translate quickly and accurately between markets it also appears that dutch investment did not destabilize london markets and stock prices in london were the primary determinant of prices in amsterdam

terrorism the relevance of the rational choice model terrorism in general and suicidal terrorism in particular is popularly seen as irrational but many economists and political scientists argue otherwise this paper distinguishes three different senses of irrationality unresponsiveness to incentives deviation from narrow self interest and failure of rational expectations it concludes that an intermediate position on the rationality of terrorism is appropriate the typical terrorist sympathizer deviates only slightly from homo economicus but active terrorists arguably stray from narrow self interest and rational expectations and suicidal terrorists probably violate both deterrence remains a viable anti terrorism strategy but deviations from rational expectations increase the potential of persuasion and appeasement

the provision of public goods via advertising existence of equilibria and welfare analysis abstract this paper considers an economy where a public good is provided via advertising the consumers preferences are represented using the characteristics approach and the advertising has a potentially enhancing effect on the characteristics content of a given commodity we define competitive equilibria and show they exist the welfare properties of the resulting allocations are analyzed and conditions for over and under production of the public good are provided

the effects of banning advertising in junk food markets we develop a structural model to analyze the eects of banning advertising on market equilibria and welfare in junk food markets we consider the impact on demand and prices and show how to quantify welfare eects when advertising might lead consumers to take decisions that are inconsistent with their underlying preferences we use transaction level data on the potato chips market and nd that banning advertising leads to a direct reduction in demand but also toughens price competition leading to lower prices and increased demand welfare increases as consumers benet from no longer making distorted

nonlinear integration of london and amsterdam stock markets in the 1700s the financial markets in london and amsterdam were some of the first to develop using threshold autoregressive models we use data on two commonly traded stocks in these cities to show that the joint behaviour of the prices is consistent with the theory of arbitrage in the presence of transportation costs the results suggest that prices converged more quickly as the price difference between the two markets increased we also show that the threshold estimates are consistent between assets and across time these results provide some of the earliest evidence of nonlinear mean reversion in asset prices in geographically separate financial markets

retrospectives consumer sovereignty the term consumer sovereignty is usually traced to william harold hutt and his 1936 book economists and the public a study of competition and opinion hutt paid only passing attention to the maximization of consumer welfare or the achievement of market efficiency he was stalking different game for him the basic issues revolved around the exercise of power in a free society and those issues concerned sovereignty why should consumers be given such great power in determining the allocation of resources and the course of production hutt s major argument for consumer sovereignty centered on its role in promoting political and social stability it is unlikely that hutt s defense of consumer sovereignty will be embraced by the economics profession in the near future it received only passing attention when first propounded and has largely disappeared from active discussion yet i would argue that his approach has a most interesting message

group consumption free riding and informal reciprocity agreements we examine conditions under which group consumption is likely to involve informal reciprocity agreements rather than a price system our model shows that reciprocity agreements are used when transactions costs are high the good is inexpensive demand is inelastic the group continues to interact over time the consumers are patient the time between interactions is short and the group is small and homogeneous further the results suggest that reciprocity agreements are likely to involve goods that are consumed along with other group benefits such as companionship we use the model to analyze overlapping social networks and investments in social capital

policy watch corporate average fuel economy standards initially the minimum corporate average fuel economy cafe program was promoted as a policy to reduce u s vulnerability to oil shocks in the past two years however concern about global warming has resulted in new political pressures to raise cafe once again to reduce the growth in u s emissions of carbon dioxide a greenhouse gas in this paper i do not attempt to provide a detailed critique of these two objectives i simply take the goals as given and draw upon estimates from the empirical literature to show that cafe is a very costly instrument for achieving them in addition i compare the costs of meeting the same objectives through a fuel or carbon tax

genetic variation in financial decision making individuals differ in how they construct their investment portfolios yet empirical models of portfolio risk typically account only for a small portion of the cross sectional variance this paper asks whether genetic variation can explain some of these individual differences following a major pension reform swedish adults had to form a portfolio from a large menu of funds we match data on these investment decisions with the swedish twin registry and find that approximately 25 of individual variation in portfolio risk is due to genetic variation we also find that these results extend to several other aspects of financial decision making

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

emergent extremism in a multi agent model of religious clubs i introduction religious extremism is as old as religion itself but the tendency to promote militancy and terrorism from within extremist religions appears to be much more common now than in times past juergensmeyer 2001 stern 2003 wiktorowicz 2005 1 today s terrorists routinely frame their objectives in religious terms and organize their activities within religious movements this shift is not due to increased militancy within religion as a whole not even within the stricter subset of religious groups commonly labeled sectarian or fundamentalist bromley and melton 2002 marty and appleby 1995 rather groups with militant objectives are increasingly leveraging the latent potential for violence within extremist religion krueger and maleckova 2003 and krueger 2007 have shown that contrary to popular hypotheses regarding the salience of poverty and education it is instead institutional conditions such as civil liberties that contribute to the origination of terrorists within a country religious extremism has been shown to be a potentially powerful input into the production of terrorism berman 2004 2 and the origination of terrorists has been empirically connected to civil liberties we seek to complete the triangle and connect religious extremism to social conditions in an extension of existing theory and test the predictions of the model in an empirical context with an eye toward civil liberties this paper extends previous models of religious clubs to better account for observed patterns of extremism across different settings and test policies most likely to reduce the appeal of extremism economists at first blush should have trouble explaining the survival of groups that demand large sacrifices from their members successful religious groups however routinely impose all sorts of apparently unproductive costs on their members iannaccone 1992 introduced a formal model of religious clubs within which apparently irrational sacrifice and stigma enhances the individual and collective utility his model demonstrated the feasibility of extremist groups but does less to explain the relative prevalence of extremism across time and place further the original model allows for only corner solutions and as such the viability of extreme groups is indistinguishable from the viability of the more moderate groups they must compete with for members in the religious marketplace in section ii we revisit analyze and extend the club model of religion we push the analysis of the original model exploring sacrifice substitutability of club and private goods and their relationships to member commitment and the viability of extremist groups in this preliminary analysis we illustrate not only the potential insights of the club theory of religion into the strength and viability of extremist groups but also the limitations inherent to the representative agent model we proceed by extending the model in a multi agent ma computational framework this framework permits us to analyze the distributions of agents and clubs that make up a religious economy the computational nature of the model is critical because it allows for sufficient heterogeneity of agents and clubs and given this heterogeneity agent decision making absent closed form solutions via nash equilibria extremists groups emerge as just one segment the high cost tail of a distribution of religious clubs that range across the full spectrum of potential group imposed sacrifice and stigma extremism is identifiable and comparable in the model because it exists within a full spectrum of clubs by varying the parameters of the model that control the distribution of secular wages across agents and the degree of substitutability between religious and secular commodities we can better explain where and when religious extremism is most popular its strength relative to more moderate groups and which economic policies reduce its prevalence

heterogeneity in the rebound effect further evidence for germany rebound effects measure the behaviorally induced offset in the reduction of energy consumption following efficiency improvements using both panel estimation and quantile regression methods on household travel diary data collected in germany between 1997 and 2009 this study investigates the heterogeneity of the rebound effect in private transport with the average rebound effect being in the range of 57 to 62 our results are in line with a recent german study by frondel peters and vance 2008 but are substantially larger than those obtained from other studies furthermore our quantile regression results indicate that the magnitude of estimated fuel price elasticities from which rebound effects can be derived depends inversely on the household s driving intensity households with low vehicle mileage exhibit fuel price elasticities and hence rebound effects that are significantly larger than those for households with high vehicle mileage

attitudes and allocations status cognitive dissonance and the manipulation of attitudes abstract economic studies of social status have typically focused on individuals engaging in relative comparisons based on certain characteristics e g consumption wealth without considering why these characteristics are deemed status worthy in this paper individuals choose a status earning characteristic in order to reduce mental discomfort dissonance as a result those individuals with the highest marginal utility from income are often the first to misconstrue or abandon these incentives in favor of alternate forms of seeking status the model provides an explanation for endogenous class formation and highlights the role of redistributive taxation in manipulating individuals attitudes towards status

the robot the party animal and the philosopher an evolutionary perspective on deliberation and preference this paper examines the evolutionary fitness of a variety of ways of reaching decisions in early hunter gatherer societies in order to derive insights about how economists should view modern consumers it challenges conclusions reached by mainstream economists robson rayo and becker about why hunter gatherers needed sensory rewards and about the kinds of preference systems that would have conferred evolutionary fitness it argues that evolution favours those with a variety of ways of reaching decisions programmed deliberative intuitive and go with the flow and that the prospect of sensory rewards serves an evolutionary role by diverting people from thinking too much about what they are doing in situations in which deliberation might interfere with survival or reproduction the evolutionary role of a reluctance or failure to make trade offs is also considered along with the benefits of developing a relatively fixed identity rather than being all things to all men

towards sustainable consumption economic modelling of mobility and heating for austria abstract the paper focuses on economic modelling and empirical analysis of sustainable structures in private consumption and strives to extend conventional economic consumption models the model analysis of sustainable consumption in the areas heating and transport for austria attempts to depart from traditional measurement of consumption in national accounts and economic consumption models the focus of the analysis is laid on consumer services derived from a combination of stocks e g building stock transport systems and flows mainly energy this approach intends to illustrate that a concentration on flows in consumption models lacks important aspects of sustainable consumption the economic analysis of sustainable consumption patterns aims to highlight the effects related to the substitution of flows by stocks in the consumption areas transport and heating e g improvements in thermal quality of buildings more energy efficient transport systems relevant too in this respect is the role that can be played by technological innovation improvements in energy efficiency of stocks the potential for specific incentives to promote new technologies two essential factors are crucial in the context of sustainable consumption the demand shifts concerning the consumer services desired and the composition of the stock flow mix necessary for the service provision

aggregation and deliberation in valuing environmental public goods starting from a distinction between kantian principle based and utilitarian preference based approaches in political theory this essay argues that we may understand normative judgments individuals make about policy to express principled views of the public interest or purpose not private preferences about their own consumption opportunities these judgments in other words state opinions about what we ought to do as a society rather than report preferences about what i want as a utility maximizer this essay then argues that contingent valuation can take into account these kinds of judgments which dominate public discourse about the environment only if it moves toward a deliberative discursive jury like research method emphasizing informed discussion leading toward a consensus based on an argument about the public interest

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

paying attention or paying too much in medicare part d we study whether people became less likely to switch medicare prescription drug plans pdps due to more options and more time in part d panel data for a random 20 percent sample of enrollees from 2006 2010 show that 50 percent were not in their original pdps by 2010 individuals switched pdps in response to higher costs of their status quo plans saving them money contrary to choice overload larger choice sets increased switching unless the additional plans were relatively expensive neither switching overall nor responsiveness to costs declined over time and above minimum spending in 2010 remained below the 2006 and 2007 levels

the simple economics of motor vehicle pollution a case for fuel tax the volume of pollution produced by an automobile is determined by driver s behavior along three margins i vehicle selection ii kilometers driven and iii on road fuel economy the first two margins have been studied extensively however the third has received scant attention how significant is this intensive margin what would be the optimal policies when it is taken into account the paper develops and analyzes a simple model of the technical and behavioral mechanisms that determine the volume emissions produced by a car the results show that an optimal fuel tax would provide drivers with appropriate incentives along all three margins and that only public information is needed for a fuel tax to be set optimally in contrast an optimal distance tax would require private information lastly relative to the optimal fuel tax a simple uniform fuel tax is shown to be progressive thus being already deployed worldwide a uniform fuel tax is an attractive second best policy these findings should be accounted for when designing new mechanisms to alleviate motor vehicle pollution

how similar are alcohol drinkers international evidence stigler and becker 1977 argue that tastes neither change capriciously nor differ importantly between people it is differences in prices and incomes that determine differences in behaviour in this paper we analyse the alcohol consumption patterns of drinkers from 8 industrialized countries we identify a number of empirical regularities and verify stigler and becker s hypothesis that income and price elasticities of demand are international constants by showing that alcohol consumption patterns in the eight countries exhibit intriguing similarities the income and price elasticities of alcohol are found to be about 0 8 and 0 6 respectively in all eight countries

the market for preferences learning processes are widely held to be the mechanism by which boundedly rational agents adapt to environmental changes we argue that this same outcome might also be achieved by a different mechanism namely specialisation and the division of knowledge which we here extend to the consumer side of the economy we distinguish between high level preferences and low level preferences as nested systems of rules used to solve particular choice problems we argue that agents while sovereign in high level preferences may often find it expedient to acquire in a pseudo market the low level preferences in order to make good choices when purchasing complex commodities about which they have little or no experience a market for preferences arises when environmental complexity overwhelms learning possibilities and leads agents to make use of other people s specialised knowledge and decision rules

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

market equilibrium and the environmental effects of tax adjustments in china s automobile industry this paper explores the effects of consumption tax and fuel tax adjustments in the chinese automobile industry applying the model and simulation method of berry levinson and pakes 1995 we conduct a comparative static analysis of equilibrium prices and sales fuel consumption and social welfare before and after tax adjustments for the first time we compare the progressivity of both taxes our empirical findings suggest that the fuel tax is effective in decreasing fuel consumption at the expense of social welfare while the consumption tax does not significantly affect either fuel consumption or social welfare

incommensurability and monetary valuation at the very heart of environmental cost benefit analysis cba is the claim that benefits and costs can be expressed in terms of money and hence made comparable in particular cba puts all benefits and costs on a cardinal monetary scale it assumes monetary commensurability a significant literature in ethics and political philosophy has arisen which doubts this assumption but has so far had little impact on the theory or practice of cba in light of this the paper assesses the defense of monetary commensurability offered by cost benefit analysts and the wider economics literature

purchasing power parity and real factors it is acknowledged that purchasing power parity ppp fails in empirical tests the position adopted is that real factors are an omitted variable from the ppp relationship and are the cause of divergences from ppp the real exchange rate as being determined by supply and demand shift factors as in stockman 1987 and neary 1988 is modelled we then empirically estimate a real exchange rate equation and use the fitted value as a generated regressor in tests of ppp it is demonstrated that when changes in the real exchange rate are incorporated into the ppp relationship ppp improves

the convoluted influence of robbins s thinking on the emergence of economics imperialism this article analyses the influence of robbins s thought on the subsequent development of economics imperialism first the analysis of some passages that have been overlooked up to the present in which the author explicitly expresses his disbelief in the omnipotence of the economic method makes it possible to argue that robbins did not share the confidence exhibited by the advocates of economics imperialism in the capacity of economics to explain non economic phenomena second this article shows that robbins describes the influence of real scarcity on human behaviour in terms of a static constrained maximization problem thereby confusing issues of method and scope in his writings this confusion facilitated the view that economics is a method without a proper subject matter and its later expansion into other fields in conclusion although robbins cannot be counted as an earlier promoter of economics imperialism the misunderstandings implicit in his writings paved the way for the emergence of this intellectual movement

world food demand long term projections of global food demand are heavily dependent on which functional form of the food demand equation is used given that real incomes can change substantially over the long term key elements are the dependence of the income elasticity on income which ensures that the food budget share always lies within the 0 1 range and the role of income inequality this article analyzes these issues proposes a new functional form that deals with them and presents estimates of income and price elasticities for food in 138 countries copyright 2012 oxford university press

consumers with differing reaction speeds scale advantages and industry structure abstract the development of an industry is seen as the outcome of a differential game in which market shares flow in response to price differences it is hypothesized that while all consumers eventually react to price differences some are slower than others if scale advantages have some influence on marginal costs around average market share then under reasonable conditions only skewed size distributions can be locally stable steady states in addition and contrary to common belief the largest firm need not eventually monopolize the industry

the equity efficiency trade off in environmental policy evidence from stated preferences the design of environmental policy raises several equity issues in particular the distribution of benefits and costs at the same time it has often been argued that there is a trade off in environmental policy between equity and efficiency which brings these issues firmly to the attention of environmental economics in this paper we use a simple choice experiment to elicit individual preferences over equity efficiency trade offs in the context of two environmental problems local air pollution and global climate change we find that equity matters to people as much as efficiency does in the design and delivery of environmental policy
