discounting and divergence of opinion the objective of this paper is to adopt a general equilibrium model and determine the socially efficient discount factor risk free rate and discount rate when there are heterogeneous anticipations about the growth of the economy as well as heterogeneous time preference rates among others we tackle the following questions is the socially efficient discount factor an arithmetic average of the individual subjectively anticipated discount factors more generally can the arrow debreu prices the risk free rates the subjectively expected socially efficient discount factors and discount rates be obtained as an average of the individual subjectively anticipated ones can beliefs dispersion be analyzed as a sort of additional risk or uncertainty leading to possibly lower discount rates is it socially efficient when diversity of opinion is taken into account to reduce the discount rate per year for more distant horizons if so what is the trajectory of the decline

how general are time preferences eliciting good specific discount rates abstract this paper tests the commonly used assumption that people apply a single discount rate to the utility from different sources of consumption using survey data from uganda with both hypothetical and incentivized choices over different goods we elicit time preferences from about 2400 subjects we reject the null of equal discount rates across goods the average person in our sample is more impatient about sugar meat and starchy plantains than about money and a list of other goods we review the assumptions to recover discount rates from experimental choices for the case of good specific discounting consistently with the theoretical framework we find convergence in discount rates across goods for two groups expected to engage in or think about arbitraging the rewards traders and individuals with large quantities of the good at home as an application we evaluate empirically the conditions under which good specific discounting could predict a low asset poverty trap

fat tails exponents extreme uncertainty simulating catastrophe in dice abstract the problem of low probability catastrophic risk is increasingly central to discussion of climate science and policy but the integrated assessment models iams of climate economics rarely incorporate this possibility what modifications are needed to analyze catastrophic economic risks in an iam we explore this question using dice a well known iam we examine the implications of a fat tailed probability distribution for the climate sensitivity parameter a focus of recent work by martin weitzman and the shape of the damage function one of the issues raised by the stern review forecasts of disastrous economic outcomes in dice can result from the interaction of these two innovations but not from either one alone

decisions under uncertainty in social contexts abstract this paper theoretically and experimentally studies decision making in risky and social environments we explore the interdependence of two decisive behavioral determinants in such environments risk attitudes and social preferences in the form of inequality aversion our model and the data demonstrate that individual risk aversion is attenuated when lagging behind peers whereas it is amplified under favorable income inequality moreover people s choices are not only context dependent but they are sensitive to their degree of inequality aversion the majority of our experimental findings cannot be rationalized by rank dependent utility models or cumulative prospect theory our results contribute to the basic understanding of the underlying motives of social incentives in firms private households saving decisions employees career track choices or charitable giving under uncertainty

how groups reach agreement in risky choices an experiment this paper studies how groups resolve disagreement when they must reach unanimity after submitting individual proposals and exchanging text form messages via a chat window in lottery choice experiments we find that the majority proposal does not always prevail the minority proposal prevails sometimes especially when it is closer to risk neutrality about one third of the groups disagrees after communication and would have got zero payoffs if disagreement remains after two more attempts without communication in these groups extrovert subjects are more likely to lead the group outcome than confused or conscientious subjects overall group choices are more coherent and closer to risk neutrality than individuals checking the recorded messages we find that the chat activity is intense growing with the level of disagreement and aims at finding consensus the amount and timing of chat messages help us to predict which choice prevails in the group

individual risk attitudes measurement determinants and behavioral consequences this paper studies risk attitudes using a large representative survey and a complementary experiment conducted with a representative subject pool in subjects homes using a question asking people about their willingness to take risks in general we find that gender age height and parental background have an economically significant impact on willingness to take risks the experiment confirms the behavioral validity of this measure using paid lottery choices turning to other questions about risk attitudes in specific contexts we find similar results on the determinants of risk attitudes and also shed light on the deeper question of stability of risk attitudes across contexts we conduct a horse race of the ability of different measures to explain risky behaviors such as holdings stocks occupational choice and smoking the question about risk taking in general generates the best all round predictor of risky behavior

an experiment on risky choice amongst households a host of experiments have examined theories of risky choice using individuals however many important economic decisions are taken within multi adult households this paper reports on the first economic experiment designed to test theories of household choice we use established couples and face them individually and jointly with decisions involving monetary payoffs we find that joint choices typically are more risk averse than those made by individuals meanwhile choices made by couples exhibit the same kinds of departures from expected utility theory e g the common ratio and common consequence effects as are regularly recorded with individuals

the sustainable borders of the state economic crises have historically set the stage for the reconfiguration of the economic borders of the state current concerns focus on debt and associated intergenerational issues such as pensions infrastructure and the environment the sustainable state is designed to put in place a framework for integrating these intergenerational issues alongside the traditional focus on macroeconomic policy static market failures and transfers the building blocks include the accounting framework and in particular a national balance sheet setting out assets and liabilities and providing for capital maintenance over time to support these assets and to provide for sufficient investment the sustainable state requires an appropriate level of savings and institutions to translate these savings into investments two components are the deployment of regulatory asset bases to underpin long term sunk and fixed costs given the time inconsistency problem in government s commitments and the development of financial intermediaries such as an infrastructure bank copyright 2011 oxford university press

the evolution of time preference with aggregate uncertainty we examine the evolutionary foundations of intertemporal preferences when all the risk affecting survival and reproduction is idiosyncratic evolution selects for agents who maximize the discounted sum of expected utility discounting at the sum of the population growth rate and the mortality rate aggregate uncertainty concerning survival rates leads to discount rates that exceed the sum of population growth rate and death rate and can push agents away from exponential discounting

distributional preferences and the incidence of costs and benefits in climate change policy we explore the relationship between willingness to pay wtp for climate change mitigation and distributional preferences by which we mean individuals opinions about who should be responsible for climate change prevention and whether the share of climate change impacts borne by the poor is a cause for concern we use 1 770 responses to an online stated preference survey the domestic costs in our survey s policy choice scenarios are expressed as a set of randomized shares across four different payment vehicles and the international cost shares are randomized across four groups of countries we also elicit respondents perceptions of the likely regressivity of climate change impacts under a policy of business as usual wtp is higher when larger cost shares are borne by parties deemed to bear a greater responsibility for mitigation and when respondents believe and care that the impacts of climate change may be borne disproportionately by the world s poor that wtp for an environmental policy depends on the distributional consequences of the policy is an unsettling result efficiency assessments are typically assumed to be separate from equity considerations in most benefit cost analyses

teams take the better risk abstract one reason why decision makers are often teams and not individuals may be that team decisions comply more closely with economic rationality we compare individual and team decisions when systematic deviations from the expected utility theory eut and the portfolio selection theory pst are to be expected we find almost no evidence for the greater compliance of team decisions with the principles of eut however there is substantial evidence for the consistency of team decisions with the pst compared to individuals teams accumulate significantly more expected value at a significantly lower total risk measured in standard deviation s d

risk aversion and incentive effects new data without order effects holt and laury 2002 used a menu of ordered lottery choices to make inferences about risk aversion under various payment conditions the main results of that paper were a subjects are risk averse even for relatively small payments of less than 5 b risk aversion increases sharply with large increases in the scale of cash payoffs and c there is no significant effect from increasing the scale of hypothetical payment with a few exceptions noted in the paper all treatments began with a low payment choice followed by a choice with hypothetical payments that had been scaled up by 20 50 or 90 followed by a real cash decision with the same high payment scale 20 50 or 90 followed by a single final low 1 real payment choice those in the 90 treatment could earn amounts ranging from 9 00 to 346 50 in this task as glenn w harrison et al 2004 correctly note this design confounds order and treatment effects since the high real payment choice was always completed after the low real and high hypothetical payment tasks in a new experiment reported below we first seek to replicate harrison et al s finding that the order effect participating in a low payment choice before making a high payment choice magnifies the scale effect in a second treatment each subject completes the menu of lottery choices under just one payment condition 1 or 20 real or hypothetical thereby eliminating any order effects i new data

health effects and optimal environmental taxes abstract the literature on environmental taxation in the presence of pre existing distortionary taxes has shown that interactions with these distortions tend to raise the cost of an environmental tax and thus that the optimal environmental tax is less than marginal environmental damages a recent paper by schwartz and repetto 2000 challenges this finding arguing that the health benefits from reduced pollution will also interact with pre existing taxes and may cause the optimal environmental tax to exceed marginal damages schwartz and repetto s analysis represented health effects implicitly in the utility function in contrast the present paper explicitly represents health effects in an analytically tractable general equilibrium model this model shows that interactions with health effects from pollution actually will tend to reduce the optimal environmental tax contradicting schwartz and repetto s conclusion this demonstrates the usefulness of explicitly modeling health effects and it reinforces the general notion that tax interactions tend to raise the costs of an environmental tax

brand credibility and marketplace globalization the role of perceived brand globalness and localness consumers in western markets are increasingly critical towards globalization and re embrace local values companies thus must decide whether to continue to pursue global branding strategies and or rejuvenate local branding strategies to explore the implications of market globalization for consumer preferences we use signaling theory to investigate the role of perceived brand globalness pbg and brand localness pbl as signals of brand credibility related downstream effects and boundary conditions across two countries with differing levels of globalization in globalized markets pbg is a weaker signal of brand credibility than pbl whereas in globalizing markets the two signals are of equal importance

are you risk averse over other people s money decisions with uncertain outcomes are often made by one party in settings where another party bears the consequences whenever an individual is delegated to make decisions that affect others such as in the typical corporate structure does the individual make decisions that reflect the risk preferences of the party bearing the consequences we examine this question in two simple settings lottery choices and sealed bid auctions using controlled laboratory experiments we find that when an individual makes a decision for an anonymous stranger there is a tendency to exhibit less risk aversion this reduction in risk aversion is relative to his or her own preferences and it is also relative to his or her belief about the preferences of others this result has significant implications for the design of contracts between principals and agents

estimating a health production function for the us some new evidence this study reports some new evidence on the impact of medical care socioeconomic lifestyle and environmental factors on the health status of the population of the usa the results show that additional medical care utilization is relatively ineffective in lowering mortality and increasing life expectancy the most important factors that influence death rates are related to socioeconomic status and lifestyle the results suggest that health care policy which focuses primarily on the provision of medical care services and ignores larger economic and social considerations may do little to benefit the nation s health

global warming discounting is not the issue but substitutability is the cost benefit study of nordhaus 1994 is representative for the neoclassical approach towards global warming nordhaus found that no substantial emission cuts are warranted most of his critics have concentrated on the issue of discounting and demanded that a lower discount rate should be applied these criticisms first miss the point and second lead to ethically dubious inconsistent conclusions and inefficient policy choices they miss the point because the real problem of nordhaus s methodology is his implicit underlying assumption of perfect substitutability between natural and other forms of capital given the validity of this assumption lowering the rate of discount is inconsistent with current savings behaviour is ethically dubious because future generations will be much richer than the current one anyway and is inefficient because scarce financial resources are channelled into emissions abatement that exhibits rates of return far inferior to alternative public investments any call for aggressive emission abatement must therefore directly attack the perfect substitutability assumption of neoclassical economics the real disagreement is about whether consumption growth can compensate for environmental degradation caused by global warming discounting is not the issue but substitutability is

the influence of global and local iconic brand positioning on advertising persuasion in an emerging market setting this study explores how positioning a brand as global and or local iconic can moderate the impact of advertising frequency af on brand attitudes in an emerging market context we argue that brands may be seen as the source of an advertisement and that the positioning of a brand can thus enhance source attractiveness and or source credibility which in turn facilitate the impact of af on brand attitudes our results support that both a global and a local iconic positioning enhance the af brand image relationship but they do not have an effect on the af brand quality relationship additionally we examine whether source attractiveness and source credibility mediate these moderation effects and find that only source attractiveness is a significant mediator additionally we investigate whether a hybrid positioning strategy i e positioning as both global and local iconic is beneficial results indicate that a separate positioning i e global or local iconic is a better strategy to increase the attractiveness of the advertising source and in turn facilitate the effect of advertising frequency to create brand image

declining discount rates economic justifications and implications for long run policy should economic policy target immediate problems like malaria and aids or should it target climate change which may have even more dramatic life threatening effects in the very long term we discuss how the pattern of discount rates over the planning horizon bears on this important issue a declining pattern of discount rates is theoretically justified by uncertainty about future economic conditions and its shape and relevance can be estimated from historical data we analyse empirically long term interest rate data from nine countries construct a weighted average representing a possible global discount rate pattern for a very long range of future dates and assess its implications for the valuation of carbon mitigation policies christian gollier phoebe koundouri and theologos pantelidis

political economy constraints on carbon pricing policies what are the implications for economic efficiency environmental efficacy and climate policy design abstract economists traditionally view a pigouvian fee on carbon dioxide and other greenhouse gas emissions either via carbon taxes or emissions caps and permit trading cap and trade as the economically optimal or first best policy to address climate change related externalities yet several political economy factors can severely constrain the implementation of these carbon pricing policies including opposition of industrial sectors with a concentration of assets that would lose considerable value under such policies the collective action nature of climate mitigation efforts principal agent failures and a low willingness to pay for climate mitigation by citizens real world implementations of carbon pricing policies can thus fall short of the economically optimal outcomes envisioned in theory consistent with the general theory of the second best the presence of binding political economy constraints opens a significant opportunity space for the design of creative climate policy instruments with superior political feasibility economic efficiency and environmental efficacy relative to the constrained implementation of carbon pricing policies this paper presents theoretical political economy frameworks relevant to climate policy design and provides corroborating evidence from the united states context it concludes with a series of implications for climate policy making and argues for the creative pursuit of a mix of second best policy instruments

group and individual risk preferences a lottery choice experiment with self employed and salaried workers abstract this paper focuses on decision making under risk comparing group and individual risk preferences in a lottery choice experiment in the individual treatment subjects make choices individually in the group treatment each subject placed in a group made lottery choice via voting in the choice treatment subjects choose whether to be on their own or in a group the originality of this research lies in the fact that we introduced variability in socio demographic characteristics by recruiting salaried and self employed workers our main findings indicate that groups are more likely than individuals to choose safe lotteries our results also show that individuals risk attitude is correlated with both the type and the sector of employment

climate policy and the social cost of power generation impacts of the swedish national emissions target the purpose of this paper is to discuss how the design of climate policy in a small open economy may affect the internalization of carbon related external costs and ultimately the social choice between different power generation technologies empirically we focus on the swedish case and analyze three climate policy regimes out of which two represent different national goal formulations and thus compliance strategies the results show that the social choice between power generation technologies in sweden will be significantly influenced by the choice of climate policy regime most notably if sweden would abandon its present national target for carbon dioxide emissions and instead make full use of the country s participation in international emissions trading natural gas fired power would replace onshore wind power as the power generation source with the lowest social cost

social discounting under uncertainty a cross country comparison recent research suggests that social cost benefit analysis should be conducted with a declining discount rate for instance newell and pizer discounting the distant future how much do uncertain rates increase valuations j environ econ manage 46 2003 52 71 show that the us certainty equivalent discount rate declines through time using a simple autoregressive model of us interest rates this paper extends that line of research estimating both autoregressive and regime switching models of real interest rates to determine certainty equivalent discount rates in australia canada germany and the uk it is found that the regime switching model is a better model of past interest rate behavior for all four countries this model tends to produce a more rapid decline in certainty equivalent discount rates the paper provides applications to the economics of climate change and nuclear power

making the implicit explicit a look inside the implicit discount rate implicit discount rates idrs are employed in energy models to capture household investment decisions yet the factors behind the idr and their respective implications for policy making usually remain blurred and fractional the proposed comprehensive framework distinguishes three broad categories of factors underlying the idr for household adoption of energy efficient technologies eets preferences notably over time risk loss debt and the environment predictable ir rational behavior bounded rationality rational inattention behavioral biases and external barriers to energy efficiency existing empirical findings suggest that the factors underlying the idrs that differ across household characteristics and technologies should be accounted for in energy models furthermore the framework allows for a fresh look at the interplay of idrs and policies we argue that a simple observation of high idrs or observing correlations between idrs and socio economic characteristics does not provide guidance for policy making since the underlying sources cannot be identified instead we propose that some of the factors underlying the idr notably external barriers can be changed through directed policy interventions whereas other factors notably preferences and predictable ir rational behavior are innate and can only be taken into account through reactive policy interventions

climate change green growth and aid allocation to poor countries with serious impacts of climate change looming in a few decades but current poverty still high in the developing world we ask how to spend development aid earmarked for the poor poverty reduction tends to be strongly linked to economic growth but growth impacts the environment and increases co2 emissions so can greener growth that is more climate resilient and less environmentally damaging deliver large scale poverty reduction can aid be used for effective poverty reduction now without affecting carbon emissions substantially we argue that there are bound to be trade offs between emissions reductions and a greener growth on the one hand and growth that is most effective in poverty reduction we argue that development aid earmarked for the poorest countries should only selectively pay attention to climate change and remain focused on fighting current poverty reduction including via economic growth not least as future resilience of these countries and their population will depend on their ability to create wealth and build up human capital now the only use for development aid within the poorest countries for explicit climate related investment ought to be when the investments also contribute to poverty reduction now including for increasing resilience to current impacts of environmental shocks or when the investments done now have serious intertemporal lock in problems so that they have implications also for when climate change bites by 2050 in our conclusions we offer a series of concrete principles to judge development spending

on modeling and interpreting the economics of catastrophic climate change with climate change as prototype example this paper analyzes the implications of structural uncertainty for the economics of low probability high impact catastrophes even when updated by bayesian learning uncertain structural parameters induce a critical tail fattening of posterior predictive distributions such fattened tails have strong im plications for situations like climate change where a catastrophe is theoretically possible because prior knowledge cannot place sufficiently narrow bounds on overall damages this paper shows that the economic consequences of fat tailed structural uncertainty along with unsureness about high temperature damages can readily outweigh the effects of discounting in climate change policy analysis

the role of path dependency and managerial intentionality a perspective on international business research several decades of research in the field of international business have advanced various theories and studies on the internationalization of firms our assessment of the literature on internationalization shows that the focus has been primarily on path dependency and learning based aspects of internationalization while managerial intentionality and the possibility of managers making deliberate strategic choices towards further internationalization have not been very prominent in the ib literature we argue that internationalization paths and processes should be approached as a joint outcome of management intentionality and experience based learning in other words managers are assumed to have the ability and the intention to influence the evolutionary paths of the firm we derive a future research agenda that calls for the pursuit of this promising and emergent research stream moreover we develop a model integrating managerial intentionality knowledge experience and other factors institutional and selection forces to explain heterogeneous outcomes of internationalization positions paths and processes

a bibliometric analysis of the global branding literature and a research agenda this study examines the citations used in the global branding literature gbl and evaluates the knowledge structure of this area of research to date our bibliometric analysis involves an examination of 120 global branding articles in business related research we employ multidimensional scaling to reveal a range of intellectual influences that have helped shape the gbl the foundation of knowledge in the gbl is uncovered by analyzing co citation data to identify important topical influences in the formation of global branding research the conceptual framework developed incorporates five areas with important implications for the future development of global branding as an area of inquiry these major research topics in the gbl are international branding strategy brand positioning brand country origin brand concept image and brand performance we leverage resource and capability based paradigms and use the five underpinning knowledge groups to propose an agenda for future research that fills existing gaps and offers the potential to advance and enrich the gbl

the stern review a deconstruction using a simple model designed for transparency but nonetheless calibrated to support the much quoted damage estimates of the stern review of the economics of climate change we demonstrate significant sensitivity of those results to assumptions about the pure rate of time preference the time horizon and the rates of risk and equity aversion used to compute certainty and equity equivalent annuities most importantly we demonstrate enormous sensitivity to presumed constant regional vulnerability and underlying assumptions about adaptive capacity manipulation of any of these parameters one at a time across reasonable ranges can diminish damage estimates by as much as 84 or in the case of extending the time horizon with the review s low discount rate increase damage estimates by 900 we also confirm the usual result that limiting atmospheric concentrations to specific benchmarks above 400 ppm cannot eliminate all damages nonetheless we applaud the stern review author team for reconfirming that the climate problem can be approached productively as an economic problem whose solutions can be explored with the tools of decision analysis 2008 elsevier ltd all rights reserved

pollution taxes and revenue recycling abstract discussions of environmental policy and the tax system have emphasized the value of pollution tax revenues which can be used to reduce other tax distortions in the economy however by raising private marginal production costs environmental taxes also tend to reduce gdp and exacerbate the welfare costs of conventional taxes for environmental taxes in consumption goods industries the net welfare change from these two effects is negative unless this good is a relatively weak substitute for leisure an estimate for the optimal pollution tax with full revenue recycling is 63 to 78 of marginal environmental damages

monetary rewards and decision cost in experimental economics a survey of thirty one experimental studies which report data on the comparative effects of monetary rewards and opportunity cost shows 1 several studies in which increased rewards shift the central tendency of the data toward the predictions of rational models 2 in virtually all cases rewards reduce the variance of the data around the predicted outcome this is consistent with a model in which rewards are balanced against decision cost in agent behavior and explicates the argument that when rational models fail it can be attributed to low opportunity cost of deviations from the rational prediction

on linking risk preferences and time preferences when estimating incentive effects this study estimates incentive effects for time preferences while jointly controlling for how incentives alter risk preferences i find traditional time preference incentive effect estimates are substantially biased when incentives also alter risk preferences

nonseparable utility and the double dividend debate reconsidering the tax interaction effect the literature on the use of environmental taxes inthe presence of distortionary labor taxes warns thata partial equilibrium pigouvian tax analysis is notappropriate because increasing the price of dirtygoods can futher aggravate the prexisting distortions this argument is most frequently made assuming thatlabor is taxed to meet a fixed revenue requirement when a dirty good is also taxed others argue thatthis lowers workers real wages causing people toreduce their labor supply below its already suboptimallevel aggravating labor market distortions however most papers ignore the effect that a cleanerenvironment can have on labor supply that is mostpast work has assumed that the quality of theenvironment is weakly separable in the utilityfunction we argue that a cleaner environment canincrease labor supply at least partially offsettingany incentive for workers to decrease their laborsupply further we show explicitly how relaxing theseparability assumption affects the standardresults

a review of the stern review on the economics of climate change the stern review calls for immediate decisive action to stabilize greenhouse gases because the benefits of strong early action on climate change outweighs the costs the economic analysis supporting this conclusion consists mostly of two basic strands the first strand is a formal aggregative model that relies for its conclusions primari ly upon imposing a very low discount rate concerning this discount rate aspect i am skeptical of the review s formal analysis but this essay points out that we are actual ly a lot less sure about what interest rate should be used for discounting climate change than is commonly acknowledged the review s second basic strand is a more intuitive argument that it might be very important to avoid possibly large uncertain ties that are difficult to quantify concerning this uncertainty aspect i argue that it might be recast into sound analytical reasoning that might justify some of the review s conclusions the basic issue here is that spending money to slow global warming should perhaps not be conceptualized primarily as being about consump tion smoothing as much as being about how much insurance to buy to offset the small change of a ruinous catastrophe that is difficult to compensate by ordinary savings

uncertainty and the demand for medical care abstract this paper provides an analysis of the effects of uncertainty on the demand for medical care using a simplified version of grossman s human capital model of the demand for health two types of uncertainty are analysed the uncertainty surrounding the incidence of illness and the uncertainty surrounding the effectiveness of medical care in the first the consumer s basic level of health is assumed to be a random variable in the second the effectiveness of medical care is assumed to be random comparative static results are reported indicating the effects on the demand for medical care of both increases in the means of these distributions and mean preserving spreads of the distributions

declining discount rates and the fisher effect inflated past discounted future uncertain and persistent real interest rates underpin one argument for using a declining term structure of social discount rates in the expected net present value enpv framework despite being controversial this approach has influenced both the inter agency working group on cost benefit analysis and the uk government s guidelines on discounting we first clarify the theoretical basis of the enpv approach then rather than following previous work which used a single series of u s treasury bond returns we treat nominal interest rates and inflation as co integrated series and estimate the empirical term structure of discount rates via the fisher effect this nests previous empirical models and is more flexible it also addresses an irregularity in previous work which used data on nominal interest rates until 1950 and real interest rates thereafter as we show the real and nominal data have very different time series properties this paper therefore provides a robustness check on previous discounting advice and updated methodological guidance at a time when governments around the world are reviewing their guidelines on social discounting the policy implications are discussed in the context of the social cost of carbon nuclear decommissioning and public health

the emergence of a regional financial architecture in asia this paper provides an assessment of monetary and financial cooperation in asia since the regional financial crisis of 1997 98 with a view to determining whether the emerging regional financial architecture in asia is compatible with the global financial architecture and what are the prospects for possible economic and monetary union monetary and financial cooperation has focused on four architectural pillars economic policy surveillance crisis prevention liquidity support and bond market development which can be consistent with the global architecture however progress toward full integration is likely to be gradual and experimental given the lack of strong regional institutions regional economic disparities and the need to build political commitment to such a goal

the behavioural economics of climate change this paper attempts to bring some central insights from behavioural economics into the economics of climate change in particular it discusses i implications of prospect theory the equity premium puzzle and time inconsistent preferences in the choice of discount rate used in climate change cost assessments and ii the implications of various kinds of social preferences for the outcome of climate negotiations several reasons are presented for why it appears advisable to choose a substantially lower social discount rate than the average return on investments it also seems likely that taking social preferences into account increases the possibilities of obtaining international agreements compared to the standard model however there are also effects going in the opposite direction and the importance of sanctions is emphasized

how individual preferences are aggregated in groups an experimental study abstract this paper experimentally investigates how individual preferences through unrestricted deliberation are aggregated into a group decision in two contexts reciprocating gifts and choosing between lotteries in both contexts we find that median group members have a significant impact on the group decision but the median is not the only influential group member non median members closer to the median tend to have more influence than other members by investigating the same individual s influence in different groups we find evidence for relative position in the group having a direct effect on influence these results are consistent with predictions from spatial models of dynamic bargaining for members with intermediate levels of patience we also find that group deliberation involves bargaining and compromise as well as persuasion preferences tend to shift towards the choice of the individual s previous group especially for those with extreme individual preferences

a dynamic analysis of human welfare in a warming planet anthropogenic greenhouse gas ghg emissions have caused atmospheric concentrations with no precedents in the last half a million years inducing serious uncertainties about future climates and their effects on human welfare recent climate science supports the view that the climate stabilization will require very low ghg emissions in the future we ask is a path of low emissions compatible with sustainable levels of human welfare with steady growth in human quality of life addressing these questions requires both defining welfare criteria and empirically estimating the possible paths of the economy we specify and calibrate a dynamic model with four intertemporal links education physical capital knowledge and the environment in line with nordhaus 2008a and with the stern review 2007 we assume that ghg emissions allow increased production while a higher stock of atmospheric carbon decreases production our index of human welfare which we call quality of life quol emphasizes education knowledge and the environment affected by greenhouse gas emissions in addition to consumption and leisure thus we avoid a consumptionist fallacy that welfare depends only on commodity consumption and perhaps leisure we reject discounted utilitarianism as a normative criterion and consider two alternatives the first is an intergenerational maximin criterion which maximizes the quality of life of the first generation subject to maintaining at least that level for all successive generations the second is human development optimization that seeks the maximization of the quol of the first generation subject to achieving a given constant rate of growth in all subsequent generations hence our analysis focuses on a human notion of sustainability as opposed to the conventional green sustainability limited to keeping the quality of the environment constant because our dynamic optimization programs defy explicit analytical solutions our approach has been computational as a benchmark we consider a simple model with physical and human capital for which we prove a turnpike theorem we then devise a computational algorithm inspired by the turnpike property to construct feasible although not necessarily optimal paths in the more complex and realistic model our analysis indicates that with ghg emission paths entailing very low emissions in the future positive rates of growth in quol are possible while the first generation experiences a quol higher than the historical reference level we also observe a tradeoff between the quality of life of the first generation and the rate of growth in the quality of life yet generation 1 s sacrifice for the sake of a higher growth rate appears to be small the paths that we compute involve investments in knowledge at noticeably higher levels than in the past

brand origin recognition accuracy its antecedents and consumers cognitive limitations an ever growing literature has reported consumer bias toward national origins of products and has explored factors that moderate such bias researchers have assumed if only tacitly that consumers are knowledgeable of brand origins and that this knowledge is a significant influence that drives judgments of product quality brand attitudes and choice behavior in the marketplace using categorization theory and attribute diagnosticity as the theoretical foundation our research reveals that consumers actually have only modest knowledge of the national origins of brands and that american consumers proficiency at recognizing foreign brand origins is predicted by variables such as socioeconomic status past international travel foreign language skills and gender in the second of two studies we determined that brand origin recognition is based largely on consumers associations of brand names with languages that suggest country origins these studies ultimately lead us to conclude that past research has inflated the influence that country of origin information has on consumers product judgments and behavior and its importance in managerial and public policy decisions

numerical analysis of non constant pure rate of time preference a model of climate policy abstract when current decisions affect welfare in the far distant future as with climate change the use of a declining pure rate of time preference prtp provides potentially important modeling flexibility the difficulty of analyzing models with non constant prtp limits their application we describe and provide software available online to implement an algorithm to numerically obtain a markov perfect equilibrium for an optimal control problem with non constant prtp we apply this software to a simplified version of the numerical climate change model used in the stern review for our calibration the policy recommendations are less sensitive to the prtp than widely believed

monitor objectivity with important clients evidence from auditor opinions around the world we examine whether monitors are likely to compromise their monitoring objectivity in the face of economically important clients in international business settings in the context of external auditing and assurance services we measure monitor objectivity by whether auditors are more or less likely to issue to their important clients modified audit opinions that is audit opinions provided to outside investors about the firm that demotes explicit areas of concern using a large cross country sample we document that auditors are more likely to issue modified opinions to their economically important clients relative to other clients furthermore we find that this association is stronger 1 for big n auditors 2 for multinational audit clients and 3 in countries with stronger legal regimes these results suggest that monitors prioritize the protection of their reputation over lucrative economic relationships and such information certification function is more pronounced for international auditors multinational client firms and in strong legal regimes

elasticity estimates from a dynamic model of interrelated demands for private and public acute health care this paper investigates the private public mix in acute health care provision in the uk it uses an interrelated shares model derived from a translog function combined with dynamic adjustment using prices for public care constructed from nhs waiting lists the insurance cost of private care and the retain price index impact intermediate and long run elasticities of demand for private and public care are obtained the role of hospital consultants and of an aging population are also considered

experimental tests of the endowment effect abstract the endowment effect which predicts undertrading and a willingness to accept greater than willingness to pay is studied using responses that remove all reference to buying or selling and focuses only on choice tasks the results significantly lower the willingness to pay willingness to accept discrepancy but the latter is still significant a high efficiency open display uniform price auction is used to exchange mugs for money since mugs are randomly assigned to half of 2n subjects n 2 mugs are predicted to trade less than n 2 mugs trade on average but more than previously reported the phenomenon exists but is less prominent than reported previously

did the stern review underestimate us and global climate damages abstract the stern review received widespread attention for its innovative approach to the economics of climate change when it appeared in 2006 and generated controversies that have continued to this day one key controversy concerns the magnitude of the expected impacts of climate change stern s estimates based on results from the page2002 model sounded substantially greater than those produced by many other models leading several critics to suggest that stern had inflated his damage figures we reached the opposite conclusion in a recent application of page2002 in a study of the costs to the us economy of inaction on climate change this article describes our revisions to the page estimates and explains our conclusion that the model runs used in the stern review may well underestimate us and global damages stern s estimates from page2002 implied that mean business as usual damages in 2100 would represent just 0 4 percent of gdp for the united states and 2 2 percent of gdp for the world our revisions and reinterpretation of the page model imply that climate damages in 2100 could reach 2 6 percent of gdp for the united states and 10 8 percent for the world

dynamic capabilities what are they this paper focuses on dynamic capabilities and more generally the resource based view of the firm we argue that dynamic capabilities are a set of specific and identifiable processes such as product development strategic decision making and alliancing they are neither vague nor tautological although dynamic capabilities are idiosyncratic in their details and path dependent in their emergence they have significant commonalities across firms popularly termed best practice this suggests that they are more homogeneous fungible equifinal and substitutable than is usually assumed in moderately dynamic markets dynamic capabilities resemble the traditional conception of routines they are detailed analytic stable processes with predictable outcomes in contrast in high velocity markets they are simple highly experiential and fragile processes with unpredictable outcomes finally well known learning mechanisms guide the evolution of dynamic capabilities in moderately dynamic markets the evolutionary emphasis is on variation in high velocity markets it is on selection at the level of rbv we conclude that traditional rbv misidentifies the locus of long term competitive advantage in dynamic markets overemphasizes the strategic logic of leverage and reaches a boundary condition in high velocity markets copyright 2000 john wiley sons ltd

economists value judgments and climate change a view from feminist economics abstract a number of recent discussions about ethical issues in climate change as engaged in by economists have focused on the value of the parameter representing the rate of time preference within models of optimal growth this essay examines many economists antipathy to serious discussion of ethical matters and suggests that the avoidance of questions of intergenerational equity is related to another set of value judgments concerning the quality and objectivity of economic practice using insights from feminist philosophy of science and research on high reliability organizations this essay argues that a more ethically transparent real world oriented and flexible economic practice would lead to more reliable and useful knowledge

optimal environmental taxation in the presence of other taxes general equilibrium analyses this paper examines the optimal setting of environmental taxes in economies where other distortionary taxes are present we employ analytical and numerical models to explore the degree to which in a second best economy optimal environmental tax rates differ from the rates implied by the pigovian principle according to which the optimal tax rate equals the marginal environmental damages both models indicate contrary to what several analysts have suggested that the optimal tax rate on emissions of a given pollutant is generally less than the rate supported by the pigovian principle moreover the optimal rate is lower the larger are the distortions posed by ordinary taxes numerical results indicate that previous studies may have seriously overstated the size of the optimal carbon tax by disregarding pre existing taxes this abstract was borrowed from another version of this item

environmental quality medical care demand and environmental tax interactions assuming that improvements in environmental quality lead to lower demand for medical care it has been shown that general equilibrium interactions with the tax distorted labor market reduce the benefits from such improvements and thus lower the second best optimal environmental tax this paper provides some insights on how the link between environmental quality individual s health capital and the demand for medical care affects the analysis of pollution taxes the paper develops structural conditions under which improvements in environmental quality decrease increase the demand for medical care and discusses their implications for environmental tax interactions

a new global deal on climate change a global target of stabilizing greenhouse gas concentrations at between 450 and 550 parts per million carbon dioxide equivalent ppm co2e has proven robust to recent developments in the science and economics of climate change retrospective analysis of the stern review 2007 suggests that the risks were underestimated indicating a stabilization target closer to 450 ppm co2e climate policy at the international level is now moving rapidly towards agreeing an emissions pathway and distributing responsibilities between countries a feasible framework can be constructed in which each country takes on its own responsibilities and targets based on a shared understanding of the risks and the need for action and collaboration on climate change the global deal should contain six key features i a pathway to achieve the world target of 50 per cent reductions by 2050 where rich countries contribute at least 75 per cent of the reductions ii global emissions trading to reduce costs iii reform of the clean development mechanism to scale up emission reductions on a sectoral or benchmark level iv scaling up of rd v an agreement on deforestation and vi adaptation finance

a cultural explanation of the foreign bias in international asset allocation abstract this paper examines the foreign bias in international asset allocation following extant literature in behavioral finance we argue that a society s culture and the cultural distance between two markets play an important role in explaining the foreign bias in particular we hypothesize that the degree of a nation s uncertainty avoidance affects the foreign bias more uncertainty avoiding countries allocate less to foreign markets as does the degree of a country s individualism in individualistic countries performance is more directly attributed to a person and less to teams causing these individuals to be more aggressive in their foreign asset allocations we further expect that the degree of cultural distance between two countries affects the amount of money allocated to that market based on extensive robustness analyses we find support for our hypotheses on the role of culture in international asset allocation

social responsibility promotes conservative risk behavior abstract previous studies show that group risk taking can be more conservative than individual risk taking two common but untested reasons for this greater caution are the influence of social responsibility and a tendency to conform to the preferences of others we study changes in risk taking in simple settings where another s risk taking can sometimes be observed and where decisions affect not only one s own payoffs but sometimes also affect those of a passive second party we find that social responsibility leads to more conservative risk behavior in group decision making conformism has a more symmetric effect observing the choice of another tends to lead both individual and social decisions toward whatever the other s expressed risk preference is direct tests fail to link the social behavior we observe to the social preference for distributional fairness common in decision making under certainty

sustainable management of fossil fuels a dynamic stochastic optimization approach with jump diffusion abstract this paper deals with a relevant aspect of energy modeling i e fossil fuels management the issue is faced by using purely operational research techniques which are suitable in this context in particular a dynamic stochastic optimization model is developed to optimally determine use and stock of resources to be employed in consumption and investments in a wide economic sense human and physical capital r d etc it is assumed that a sustainability criterion drives the optimality rules i e decisions are also grounded on the well being of future generations the policymaker maximizes an aggregated intergenerational expected utility under the dilemma of present consumption conservation of natural resources for the future in reference to standard environmental economic theory jump diffusion dynamics for the stock of natural resources and infinite time horizon are assumed extensive numerical experiments complete the analysis and contribute to determine fossil fuels management policies showing that long term investments make the difference for the well being of present and future generations

a quantitative minimax regret approach to climate change does discounting still matter abstract using cost benefit analysis to determine an optimal climate mitigation target is criticised especially because i it fails to sufficiently take into account low probability high impact events and ii results strongly depend on the discount rate used one of the alternative suggestions to inform policymakers about the right mitigation target that does take the risks associated with low probability high impact events explicitly into account is the minimax regret criterion we apply the minimax regret criterion quantitatively using an integrated assessment model with extreme values for climate sensitivity damage estimates and mitigation costs the goal is to analyse whether such a method leads to different results compared to standard cost benefit analysis and whether the results are still sensitive to the discount rate used we find that the minimax regret approach leads to more stringent and robust climate targets for relatively low discount rates and if both a high climate sensitivity and high damage estimates are assumed if one of these assumptions does not hold the difference between the minimax regret approach and standard cost benefit analysis is much smaller therefore we conclude that the discount rate used can still be of vital importance even when applying a minimax regret approach

description prescription and the choice of discount rates abstract the choice of discount rates is a key issue in the analysis of long term societal issues in particular environmental issues such as climate change approaches to choosing discount rates are generally placed into two categories the descriptive approach and the prescriptive approach the descriptive approach is often justified on grounds that it uses a description of how society discounts instead of having analysts impose their own discounting views on society this paper analyzes the common forms of the descriptive and prescriptive approaches and finds that in contrast with customary thinking both forms are equally descriptive and prescriptive the prescriptions concern who has standing i e who is included in society how the views of these individuals are measured and how the measurements are aggregated such prescriptions are necessary to choose from among the many possible descriptions of how society discounts the descriptions are the measurements made given a choice of measurement technique thus the labels descriptive approach and prescriptive approach are deeply misleading as analysts cannot avoid imposing their own views on society

environmental tax interactions when pollution affects health or productivity abstract recent studies indicate that interactions with the tax distorted labor market increase the cost of pollution regulation however these studies make restrictive assumptions regarding preferences and ignore key links between pollution human health and labor productivity together these assumptions imply that pollution does not affect labor supply this paper develops an analytical general equilibrium model that considers several potential benefits from reduced pollution including improved health or productivity it shows that these benefits affect labor supply and thus create a benefit side tax interaction effect that can be of the same magnitude as the familiar cost side interaction when reduced pollution boosts labor productivity the effect substantially magnifies such benefits in contrast when pollution affects consumer health the effect tends to diminish the benefits of reduced pollution the paper considers only environmental regulation but these concepts apply equally to other policies affecting productivity or health such as research subsidies or occupational safety regulations

examining risk preferences under high monetary incentives experimental evidence from the people s republic of china several experimental sessions were conducted to elicit certainty equivalents for a sequence of lotteries involving real monetary outcomes the opportunity to conduct sessions in the people s republic of china afforded the ability to offer very large monetary incentives relative to subjects living costs in the highest payoff condition subjects earned three times their normal monthly revenue in the course of a two hour experiment results indicate a statistically significant impact of the level of monetary incentives on revealed risk preferences however even under extreme monetary incentives subjects demanded amounts well in excess of expected value for low probability gain prospects copyright 1992 by american economic association

source or storer ib s performance in a knowledge network the absence of systematic assessment of ib s performance as a reference discipline prolongs questioning of the contribution that ib scholarship makes to other business fields put simply do ib journals export more ideas to allied disciplines than they import from them difficulty in evaluating the merits of let alone the need for solutions offered to boost interdisciplinary relevance slows validation of the ontological principles and epistemic standards of ib research this paper begins to fill this gap it establishes a knowledge network composed of 39 high impact journals that represent the domains of management marketing finance economics operations it accounting human resources organizational behavior and ib we collected citation exchanges among these 39 journals from 2000 through 2007 a log multiplicative model evaluated multiple dimensions of association to determine the sources and storers of knowledge within the network the network from pathfinder analysis was used to determine each journal s contribution to network entropy these analyses indicate that ib journals functioned as storers not sources of ideas within the sampled knowledge network over the studied period the results help interpret opposing proposals to fortify ib studies highlight the tradeoff between exploitation and exploration in knowledge development and dissemination and elaborate jibs s boundary spanning performance within the sampled network

mnc subsidiary channel relationships as extended links implications of global strategies foreign subsidiaries of multinational corporations mncs rely on external partners such as channel partners to achieve global objectives we conceptualize the subsidiary s channel partner as an extended link of the mnc s internal network thus the subsidiary s adaptation and execution of the mnc s global strategies should influence the subsidiary s channel relationship and performance building on the strategy environment alignment framework we study the influence of mnc global strategies global efficiency multinational flexibility and worldwide learning on a subsidiary s channel commitment and the moderating influence of the host country environment survey data from german and japanese mncs in the united states indicate the importance of global strategies to a channel relationship for example we find that an emphasis on multinational flexibility is detrimental but worldwide learning benefits the subsidiary s channel commitment we also find that the host country environment plays a contingent role for example a global efficiency strategy is beneficial for channel commitment in a stable environment but detrimental in a dynamic environment our research offers key implications for mncs we suggest that when mncs decide to lay emphases on global strategies the mncs should consider not just their internal subsidiary network but also their extended channel partner links that function in foreign markets

the impact of climate change on the balanced growth equivalent an application of fund the stern review added balanced growth equivalents bge to the economic climate change research agenda we first propose rigorous definitions of the bge for multiple regions and under uncertainty we show that the change in the bge is independent of the assumed scenario of per capita income for comparable welfare economic assumptions as the stern review we calculate lower changes in bge between a business as usual scenario and one without climate impacts with the model fund than the stern review found with the model page we find that mitigation policies give even lower changes in bge and argue that those policy choices should be the focus of the research effort rather than total damage estimates according to our results the current carbon tax should be below 55 tc sensitivity analyses show that the stern review chose parameters that imply high impact estimates however for regionally disaggregated welfare functions we find changes in bge that are significantly higher than the results from the stern review both for total damage as for policy analysis with regional disaggregation and high risk aversion we observe fat tails and with that very high welfare losses

a review of the stern review on the economics of climate change how much and how fast should we react to the threat of global warming the stern review argues that the damages from climate change are large and that nations should undertake sharp and immediate reductions in greenhouse gas emissions an examination of the review s radical revision of the economics of climate change finds however that it depends decisively on the assumption of a near zero time discount rate combined with a specific utility function the review s unambiguous conclusions about the need for extreme immediate action will not survive the substitution of assumptions that are consistent with today s marketplace real interest rates and savings rates

a regional dynamic general equilibrium model of alternative climate change strategies outcomes and noncooperative equilibria this study finds that cooperative policies show much higher levels of emissions reductions than do noncooperative strategies that there are substantial differences in the levels of controls in both the cooperative and the noncooperative policies among different countries and that high income countries may be the major losers from cooperation jel h41 q4 q2 q20

ethics of the discount rate in the stern review on the economics of climate change any comparison of the costs and benefits of climate change is dominated by the chosen discount rate but although the stern review emphasises the ethical nature of the parameters entering into its choice of a relatively low discount rate its discussion of the pure time preference parameter is unbalanced in particular no consideration is given to the role of agent relative ethics which i has a wellestablished philosophical pedigree going back to david hume ii is likely to correspond closely to world wide public attitudes towards intergenerational welfare and iii would entail discounting a unit of welfare accruing to future generations compared to an equal unit accruing to people alive today at a positive rate the authors also discuss the other ethical parameter upon which the discount rate depends namely the elasticity of marginal utility with respect to consumption in the conventional model this simultaneously reflects different aspects of inequality aversion as well as risk aversion which complicates its interpretation finally they discuss the divergence between market rates of discount and the low rate chosen in the review and the limitations on the one hand on the normative significance of market rates as well as the danger on the other hand of relying on rates chosen by elites or philosopher kings

the structure of jibs s social network and the relevance of intra country variation a typology for future research we examine articles published in the journal of international business studies jibs and introduce a typology to support the relevance of intra country variation in international business ib based on social network theory our analysis uses multidimensional scaling to study 53 203 citations from 1158 qualifying jibs articles to determine the journal s social structure the results indicate that three current research clusters multinational enterprise knowledge development foreign entry and cultural effects and the internationalization process and national culture are based on established ib theory then we respond to calls in the literature to improve research concerning intra country variation and propose a typology of three dimensions social demographic and geographic to study the diversity of individual firm and economic activity in a country the social dimension evaluates the importance of modernist and traditionalist values the demographic dimension proposes differences between urban and rural settings and the geographic dimension discusses the relevance of border and interior locations we suggest a nested typology that unifies these three dimensions for continued use in ib future research opportunities related to jibs s social structure and the intra country variation typology are recommended

the less you discount the more it shows you really care interpersonal discounting in households abstract household members make monetary tradeoffs across time classical economics treats these decisions as if one rational individual makes them this assumption masks important other regarding concerns between spouses we designed an artefactual field experiment and collected data from 94 pairs of cohabiting couples to capture the complex nature of intra household time preferences estimation results show that 1 the interpersonal discount rate the rate used to tradeoff intertemporal payoffs between one s own payoff and the spouse s payoff is significantly different from the individual discount rate and 2 the interpersonal discount rate may provide an alternative way for people to express their other regarding preferences towards their spouses

on the collapse of historical civilizations to explain the collapse of historical civilizations scholars typically point to suboptimal behaviors including misunderstanding the natural environment shortsightedness or a lack of institutions we examine the collapse of four historical societies with a model of endogenous population growth and renewable resources employing components of optimal resource management economic growth theory and the moral philosophy of social welfare function choice we find that these collapses may have been socially optimal further we show that the transient behavior of the system is more sensitive to assumptions than the equilibrium behavior and that focusing solely on equilibria may miss key insights copyright 2009 oxford university press

discounting for personal and social payments patience for others impatience for ourselves the market rate of return on private investment is often used as the discount rate when conducting cost benefit analysis cba of public projects i argue that the decision to invest pits current consumption against future consumption both of which accumulate to the private decision maker public projects on the other hand provide benefits that accrue to society in general to examine the appropriateness of discount rates based on returns to private investment this paper considers lab experiments designed to test whether individuals discount personal and social benefits at different rates personal benefits are captured through personal monetary payments while social benefits are captured through anonymous donations to charitable organizations i jointly elicit time and risk preferences and find that subjects discount charitable contributions at significantly lower rates than personal payments

time perspective and climate change policy the tendency to foreshorten time units as we peer further into the future provides an explanation for hyperbolic discounting at an inter generational time scale we study implications of hyperbolic discounting for climate change policy when the probability of a climate induced catastrophe depends on the stock of greenhouse gasses we characterize the set of markov perfect equilibria mpe of the inter generational game amongst a succession of policymakers each policymaker reflects her generation s preferences including its hyperbolic discounting for a binary action game we compare the mpe set to a restricted commitment benchmark we compare the associated constant equivalent discount rates and the willingness to pay to control climate change with assumptions and recommendations in the stern review on climate change ymy picture of the world is drawn in perspectivey i apply my perspective not merely to space but also to time ramsey

endogenous discounting and climate policy under risk of abrupt climate change the occurrence hazard is added to the social discount rate as a result the social discount rate 1 increases and 2 turns endogenous to the global warming policy the second effect bears profound policy implications that are magnified by economic growth in particular we find that greenhouse gases ghg emission should be terminated at a finite time so that the ensuing occurrence risk will vanish in the long run due to the public bad nature of the catastrophic risk the second effect is ignored in a competitive allocation and unregulated economic growth will give rise to excessive emissions in the long term the ghg emission paths under the optimal and competitive growth regimes lie at the extreme ends of the range of feasible emissions
