improvement of technical efficiency of firm groups abstract cooperation between firms can never improve the technical efficiency of any firm coalition the directional distance function by virtue of its additive nature is a useful tool that outlines this impossibility in this paper the additive aggregation scheme of input output vectors is generalized according to an aggregator accordingly cooperation between firms may increase the technical efficiency of the firm group this improvement is shown to be compatible with nonjoint semilattice technologies that bring out either output or input weak complementarity firm games are investigated to show that firms may merge on the basis of their inputs due to constraints imposed on outputs conversely they may merge with respect to the outputs they can produce because of limitations imposed on inputs

market and nonmarket influences on curriculum choice by college students many labor economists and other researchers have attempted to develop models of the workings of the market for college trained manpower this paper reviews this previous research on curriculum choice and then tests an alternative model with data on choices made by male baccalaureates across a wide spectrum of science and engineering curricula the influence of both methodology and the analytical framework on the identification of relevant variables is explored particular attention is then given to nonmarket influences typically assumed in previous studies not to play a significant role results for pooled and time series specifications provide some support for the hypothesis that curriculum choice follows labor market developments but they also suggest that abilities and interests may be important predictors

is economic growth good for the poor tracking low incomes using general means in this paper we propose the use of an alternative methodology to track low incomes based on atkinson s 1970 family of equally distributed equivalent income functions which are called general means here we provide a new characterization of general means that justifies their use in this context our method of evaluating the effects of growth on poor incomes is based on a comparison of growth rates for two standards of living the ordinary mean and a bottom sensitive general mean the motivating question is to what extent is growth in the ordinary mean accompanied by growth in the general mean a key indicator in this approach is the growth elasticity of the general mean or the percentage change in the general mean over the percentage change in the usual mean our empirical analysis estimates this growth elasticity for a data set containing 144 household surveys from 20 countries over the last quarter century among other results we find that the growth elasticity of bottom sensitive general means is positive but significantly smaller than one this suggests that the incomes of the poor do not grow one for one with increases in average income

citizens of the green world cosmopolitan orientation and sustainability contemporary consumer markets are characterized by both a heightened need for sustainability and an increasingly cosmopolitan lifestyle this article bridges these two trends and studies two untapped questions 1 how do cosmopolitan consumers relate to sustainable behavior and 2 how should environmental messages be framed to successfully target cosmopolitan consumers four studies in three countries show that high cosmopolitan consumers demonstrate environmental concern and engage in sustainable behavior to successfully target this promising segment with sustainable products or messages to promote sustainable behavior marketers and public policymakers should highlight the benefit of these products behaviors for the global rather than the local environment however the findings also show that high cosmopolitan consumers can be successfully targeted to support local environmental initiatives when activating their local identification the article offers implications for businesses non government organizations and public policymakers in designing effective messages to promote sustainable behavior

discounting risk and inequality a general approach the common practice consists in using a unique value of the discount rate for all public investments endorsing a social welfare approach to discounting we show how different public investments should be discounted depending on the risk on the returns on investment the systematic risk on aggregate consumption the distribution of gains and losses and inequality we also study the limit value of the discount rate for very long term investments we highlight the type of information that is needed about long term scenarios in order to evaluate investments

marketing mix and brand sales in global markets examining the contingent role of country market characteristics marketing products globally is challenging due to the diverse nature of markets we use market heterogeneity unbranded competition resource and infrastructure availability and sociopolitical governance as country market characteristics that distinguish between developed and emerging countries we investigate their moderating role on the relationship between elements of the marketing mix and brand sales we provide evidence from a hierarchical linear model and a panel data set of brands from 14 emerging and developed markets that account for 62 of the global gdp that country market characteristics moderate the relationship between the complete set of marketing mix elements and brand sales performance asymmetrically while distribution and price have the largest impact in emerging and developed countries respectively product innovation and advertising have significantly larger impacts in emerging markets relative to developed countries these finding highlights the importance of contingency view of marketing strategy in global markets

cosmopolitan consumers as a target group for segmentation for international companies the literature recommends directing segmentation efforts at customer characteristics rather than country characteristics consumers degree of cosmopolitan orientation has been suggested as a powerful segmentation base as this characteristic is expected to drive consumers tastes and preferences to advance research on this segmentation base this article offers a conceptualization of the consumer cosmopolitanism construct by 1 delineating its conceptual domain 2 highlighting its key dimensions namely open mindedness diversity appreciation and consumption transcending borders and 3 examining its links with theoretically relevant variables specifically consumer ethnocentrism and global consumption orientation based on the aforementioned conceptualization a consumer research specific and psychometrically sound measurement instrument the c cosmo scale is subsequently developed and tested in a series of complementary studies finally empirically based insights into the characteristics of cosmopolitan consumers are offered by 1 profiling them on consumption relevant variables innovativeness risk aversion susceptibility to normative influence consumer ethnocentrism and demographic characteristics 2 examining the link between consumer cosmopolitanism and willingness to buy foreign products and 3 developing an empirically based typology of cosmopolitan local consumers using a cluster analysis approach from a managerial perspective findings suggest that the identification and subsequent targeting of cosmopolitan consumers may well represent an appropriate strategy for internationally active companies

ethical social index numbers and the measure ment of effective tax benefit progressivity in this paper we propose a general method for constructing measures both relative and absolute of effective tax benefit progressivity from social welfare functions relative measures compare the after tax or benefit distribution of income with the distribution that would result if the burden were imposed proportionally absolute measures use the equal taxation of individuals as a benchmark these indices are related to relative and absolute indices of inequality our relative indices are generalizations of the gini index based musgrave thin measure of effective progressivity we compare our general indices to the proposals of kakwani khetan and poddar and suits

price independent welfare prescriptions and population size abstract this note investigates the extension of roberts price independent welfare prescriptions to alternatives in which population size and composition can vary we show that ethically unsatisfactory orderings result suppose that a single person is to be added to a population that is unaffected in utility terms either all such additions must be regarded as bad or some expansions in which the added person s life is not worth living must be ranked as social improvements journal of economic literature classification number d63

welfare specifications and optimal control of climate change an application of fund the sensitivity of the optimal control of carbon dioxide emissions to the specification of the social welfare function is systematically explored using the fund model increasing risk aversion emphasises climate change damages relative to emission reduction costs but at the same time increases the discount rate of consumption without international co operation the discount rate effect dominates so that optimal control decreases with increasing risk aversion with international co operation optimal control first increases then decreases with increasing risk aversion since climate change falls heaviest on the poor optimal control increases with increasing inequity aversion full fledged intergenerational welfare functions on the one hand emphasise climate change damages but on the other hand place more weight on current poorer generations in fund the two tendencies almost cancel

income redistribution in a common labor market when households are mobile among jurisdictions income redistribution by individual jurisdictions creates fiscal externalities a model of interjurisdictional migration is used to study the nature of this redistributive externality analysis of optimal redistribution and optimal corrective subsidies from higher level governments shows that benefit levels for the recipients of income transfers and tax rates on mobile taxpayers should be equalized across jurisdictions a system of jurisdictions with a common labor market can achieve welfare improvements through coordination of domestic redistributive policy or through the intervention of a higher level government copyright 1991 by american economic association

inequality in male and female earnings the role of hours and wages the authors decompose annual earnings into hours of work and hourly earnings and analyze male female differences in earnings inequality using canadian data their results indicate that the larger female inequality in earnings is due to a greater inequality in the distribution of hours of work the distributions of wages for men and women are either statistically indistinguishable or more equal for women the authors compare two data points 1988 and 1981 and find the same structure in the gender comparisons also changes between 1988 and 1981 in earnings inequality are generated from movements in the hours distributions copyright 1996 by mit press

is global social welfare increasing a critical level enquiry abstract we assess whether global social welfare has improved in the last decades despite or because of the substantial increase in global population we use for this purpose a relatively unknown but simple and attractive social evaluation approach called critical level generalized utilitarianism clgu clgu posits that social welfare increases with population size if and only if the new lives come with a level of living standards higher than that of a critical level despite its attractiveness clgu poses a number of practical difficulties that may explain why the literature has left it largely unexplored we address these difficulties by developing new procedures for making partial clgu orderings the headline result is that we can robustly conclude that world welfare has increased between 1990 and 2005 if we judge that lives with per capita yearly consumption of more than 1 248 necessarily increase social welfare the same conclusion applies to sub saharan africa if and only if we are willing to make that same judgment for lives with any level of per capita yearly consumption above 147 otherwise some of the admissible clgu functions will judge the last two decades increase in global population size to have lowered global social welfare

the cross cultural research imperative the need to balance cross national and intra national diversity this paper provides a brief overview of the evolution of comparative management theories paradigms and highlights the contribution of the cross vergence construct despite progress most studies of work values across countries continue to suffer from two primary limitations the first is the fallacious assumption of cultural homogeneity with nations given the growing diversity of the workforce within country intra national variations can often be as significant as cross national differences the second is the fallacious assumption of cultural stability over time since cultures evolve albeit slowly it is important to take these changes over time into consideration and be aware of the paradoxes inherent within any given society hence the paper calls for the need to balance cross national and intra national diversity in order to truly understand cross cultural phenomena and thus further improve the quality of cross cultural research

testing for poverty dominance an application to canada the paper proposes and applies statistical tests for poverty dominance that check for whether poverty comparisons can be made robustly over ranges of poverty lines and classes of poverty indices this helps provide both normative and statistical confidence in establishing poverty rankings across distributions the tests which can take into account the complex sampling procedures that are typically used by statistical agencies to generate household level surveys are implemented using the canadian survey of labour and income dynamics slid for 1996 1999 and 2002 although the yearly cumulative distribution functions cross at the lower tails of the distributions the more recent years tend to dominate earlier years for a relatively wide range of poverty lines failing to take into account slid s sampling variability as is sometimes done can inflate significantly one s confidence in ranking poverty taking into account slid s complex sampling design as has not been done before can also decrease substantially the range of poverty lines over which a poverty ranking can be inferred

investment in human and nonhuman capital transfers among siblings and the role of government the implications for efficient allocation of parents inability to force transfers among siblings are explored when there are differences in abilities of children within families such transfers may be necessary to achieve a first best solution in the absence of such transfers a tax on earned income and a subsidy to inheritance are useful second best tools whereas subsidies to investments in human capital or physical capital are not desirable

endogenous population with public goods and malthusian fixed resources efficiency or market failure a theoretical population model is developed which takes into account both the desire of a nation for a large population for political and economic reasons as well as the malthusian pressures that suggest that there is a natural tendency toward overpopulation the model assumes that parents care about both the number and well being of their children the results show that these two possible sources of externality do not lead to market failure nor to unfettered competitive individual decisions concerning childbearing that are detrimental to society annotation

preferences and prices in choice of career the switch to business 1972 1987 abstract in the last two decades the largest single change in career plans of college students is the more than doubling from 1972 to 1987 of the proportion opting for business the evidence suggests that a shift in preferences a marked upsurge among the young in money making as a life goal was responsible for this as well as movements in prices the relative returns from different occupations the rise in interest in money making is not due to greater insecurity among the young about their economic future or worsened job expectations rather it reflects greater concern about money among older adults which influenced the young with a lag by re shaping their life goals as they grew up empirical study of occupational choice would benefit from more attention to such non market influences

deeds not words a cosmopolitan perspective on the influences of corporate sustainability and ngo engagement on the adoption of sustainable products in china to make a business case for corporate sustainability firms must be able to sell their sustainable products the influence that firm engagement with non governmental organizations ngos may have on consumer adoption of sustainable products has been neglected in previous research we address this by embedding corporate sustainability in a cosmopolitan framework that connects firms consumers and civil society organizations based on the understanding of responsibility for global humanity that underlies both the sustainability and cosmopolitanism concepts we hypothesize that firms sustainability engagement and their ngo engagement influence consumer adoption of sustainable products empirically we investigate the adoption of sustainable eco circle products made from recycled fibers marketed by li ning a china based global sportswear brand we apply a stepwise regression approach to test our hypotheses with paper and pencil survey data from 217 chinese consumers we find adoption to be positively associated with consumers sustainability attitude but not with firms sustainability engagement for firm ngo engagement these relationships are reversed adoption is positively associated with firm ngo engagement but not with consumers related attitude our results present a picture of the chinese context in which there is a business case for corporate sustainability if firms words about sustainable product strategies are supported by signals from civil society about firm deeds the results imply that in a chinese context firms need to be particularly aware of the role of ngos when hoping to be rewarded for sustainability

a consistent multidimensional pigou dalton transfer principle abstract the unidimensional pigou dalton transfer principle demands that a regressive transfer in income a transfer from worse off poor to better off rich decreases social welfare in a multidimensional setting the direct link between income or any other attribute and individual well being is absent we interpret the social welfare level of a distribution in which each individual has the same bundle as the individual well being level we define regressivity on the basis of this individual well being ranking in a setting with both transferable and non transferable attributes the imposition of the ensuing consistent pigou dalton principle forces individual well being to have a quasi linear structure in the transferable attributes since we allow for transferable and non transferable attributes our result provides a normative underpinning for criteria in the distinct literatures of multidimensional inequality measurement only transferable attributes and of needs one transferable and one non transferable attribute

equivalent expenditure functions and expenditure dependent equivalence scales abstract this paper presents and investigates a new class of equivalent expenditure functions that is a generalization of the one that corresponds to exact independent of base equivalence scales it provides less restrictive household demands especially for children s goods and has associated equivalence scales that may depend on expenditure we show that under certain conditions equivalent expenditure functions and the associated expenditure dependent equivalence scales can be uniquely estimated from demand data we estimate them using canadian data and find that the resulting scales are both plausible and expenditure dependent the estimated equivalence scales for households with children decline significantly as expenditure increases

the equal absolute sacrifice principle revisited abstract we summarize the literature on equal absolute sacrifice income taxes and make some extensions we adapt the utilitarian equal sacrifice criterion to a wide class of rank dependent social welfare functions and find that liabilities depend on both income and position in the distribution we investigate whether such taxes need be progressive using a combination of analytics and simulation and in the process uncover tax functions not previously recognized as equating sacrifices finally out of horizontal equity considerations a new concept of the equal treatment of equals by an income tax emerges with implications for future work whose significance is discussed

quality quantity and duration of lives the evaluation of development processes and of public policies often involves comparisons of social states that differ in income distributions population sizes and life longevity this may require social eva luation principles to be sensitive to the quality the quantity and the duration of lives this paper 1 reviews some of the normative issues at stake 2 proposes and discusses some specific methods to address them in a generalized utilitarian framework and 3 briefly illustrates the application of som e of these methods to the global distribution of incomes population sizes and longevity over the last century depending on the approach taken it is found inter alia that global social welfare in 2010 can be deemed to be between 1 8 and 407 times that of 1910 the role given to the quantity of lives bei ng particularly important in that assessment

forming wage expectations through learning evidence from college major choices abstract how do college students choose their majors and what role does the family play in their choices i use data from two major longitudinal surveys to develop and estimate a model in which students learn about earning opportunities associated with different majors through the wages of older siblings and parents the probability of a student choosing a major that corresponds to the occupation of a family member is strongly correlated with the family member s wage at the time the major choice is made this correlation remains strong after controlling for family correlated abilities or preferences and additional empirical evidence suggests that the observed correlation arises through a family based wage information channel

foreign aid and population policy some ethical considerations abstract this paper analyzes a two period foreign aid model where assistance can be given in the form of consumption or population control aid population size in period 2 is endogenous using the family of ethical principles called critical level utilitarianism clu we examine the properties of ethically optimal resource allocations our results show that the direction of the ethical response of population size to changes in the cost of population control and the size of the grant depends on the relationship between the critical level of well being an ethical parameter and the standard of living in the recipient country

social welfare and interpersonal utility comparisons in applied policy research it is a fair generalization to say that most applied policy analysis during the past half century has been conducted according to compensation principles a policy change has been thought potentially desirable if the sum over all individuals of the subjective money value of the change is positive whether winners should compensate losers is a separate issue left to politicians this paradigm is expedient because it is unconcerned about whether in the absence of full compensation the policy change is good or bad and because the pareto principle upon which it rests is very weak it suggests that welfare economics has achieved the status of a value weak science the only problem remaining would be to refine the measures of an individual s money equivalent of an economic change hallam unfortunately the compensation test has proved to be an inadequate analytical tool its inadequacy does not arise from the oftenmentioned difficulties with utility change measurement uncertainty or preference reversals rather it arises from a failure to fully address questions that policy makers ask to which framework should one turn if as is likely compensation is very costly or if it alters resource allocations stiglitz p 31 runge and myers even if compensation is costless and nondistorting how should one think about the desirability of compensation itself to answer these questions satisfactorily one must appeal to social welfare functionals and to the interpersonal and ethical information the functionals incorporate in the following a social welfare approach to applied policy research is outlined and some issues in implementation are discussed

looking at the population problem through the prism of heterogeneity welfare and policy analyses upon introducing heterogeneity and dynamics into a model of the demand for children a problem of optimal population is defined and analyzed it is shown that from the perspective of social welfare better educated individuals produce too few children while less educated individuals produce too many children and all individuals invest too little in the education of their children the impact of several policy tools geared at addressing the population problem is investigated in particular how child allowances and other tax subsidy policies can be harnessed to enhance welfare and how and why early childhood education programs can mitigate the population problem

relative price changes and inequality in the size distribution of various components of income this article uses a comprehensive model of economic inequality to examine the impact of relative price changes on inequality in the marginal distributions of various income components in which the marginal distributions are derived from a multidimensional joint distribution the multidimensional joint distribution function is assumed to be a member of the pearson type vi family that is it is assumed to be a beta distribution of the second kind the multidimensional joint distribution is so called because it is a joint distribution of components of income and expenditures on various commodity groups gini measures of inequality are devised from the marginal distributions of the various income components the inequality measures are shown to depend on the parameters of the multidimensional joint distribution it is then shown that the parameters of the multidimensional joint distribution depend on the relative prices of various commodity groups and several other specified exogenous variables thus knowle

birth date dependent population ethics critical level principles abstract this paper investigates birth date dependent principles for social evaluation in an intertemporal framework in which population size may vary we weaken the strong pareto principle in order to allow individuals birth dates to matter in establishing a social ordering using the axiomindependence of the utilities of the dead we characterize population principles with a recursive structure if the individual substitution principle and an individual intertemporal equivalence axiom are added birth date dependent generalizations of the critical level generalized utilitarian principles result stationarity leads to the special case of geometric discounting journal of economic literatureclassification numbers d63 d71

social criteria for evaluating population change abstract many applications of economic analysis require social evaluations of alternatives involving different numbers of people in this paper we use the tools of social choice theory to provide an axiomatic formulation of this problem it yields a class of social criteria called critical level generalized utilitarianism this class and its implications are compared with other criteria and are found to yield intuitively appealing results

from the editors common method variance in international business research jibs receives many manuscripts that report findings from analyzing survey data based on same respondent replies this can be problematic since same respondent studies can suffer from common method variance cmv currently authors who submit manuscripts to jibs that appear to suffer from cmv are asked to perform validity checks and resubmit their manuscripts this letter from the editors is designed to outline the current state of best practice for handling cmv in international business research

consumption needs and inequality most empirical studies demonstrating a u turn in inequality in the united states are based on the distribution of income however utility is derived from the consumption of goods and services and there are many reasons to expect the distribution of expenditure to be different from the distribution of income the author demonstrates that consumption based inequality indexes actually decrease over the postwar era this conclusion differs from the stylized facts because of differences in the income and expenditure distributions differences also arise from the inclusion of equivalence scales to account for the different needs of heterogeneous households copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

intertemporal population ethics critical level utilitarian principles this paper considers the problem of social evaluation in a model where population size individual lifetime utilities lengths of life and birth dates vary across states in an intertemporal framework we investigate principles for social evaluation that allow history to matter to some extent using an axiom called independence of the utilities of the dead we provide a characterization of critical level generalized utilitarian rules as a by product of our analysis we show that social discounting is ruled out in an intertemporal welfarist environment a simple population planning example is also discussed

an intergenerational model of population growth the problem of population growth has been only partially formulated in an intertemporal context therefore a link between population theory and economic growth theory is still missing this paper attempts to provide such a link by analyzing an intergenerational model of optimum population growth the model accommodates the idea that decisions on increases in population should consider the new population s quality of life this concept is elaborated upon in a static framework by gary becker and gregg lewis dennis de tray and robert willis other literature on population growth such as harold votey disregards this consideration altogether 2 more explicitly this paper assumes that the utility of each generation is a function of the level of its consumption and the number and utility of the newly born people we are thus led to consider the utility of an infinite number of generations this model differs from paul samuelson s intergenerational model of pure consumption in which the utility of each generation depends only on that generation s own consumption recently philip neher 1971 analyzed a model of fertility in primitive economies it is based on the assumption that parents use children as investments to insure future consumption needs neher s analysis focuses entirely on the pension motive for having children 3 our model assumes that fertility is determined so as to balance the parents welfare derived from additional children against that derived from the children s quality of life we first outline a general model of optimum population growth in order to discuss explicitly various economic aspects of population we use a simple case in the analysis section i sets up the basic model

quadratic social welfare functions john harsanyi has provided an intriguing argument that social welfare can be expressed as a weighted sum of individual utilities his theorem has been criticized on the grounds that a central axiom that social preference satisfies the independence axiom has the morally unacceptable implication that the process of choice and considerations of ex ante fairness are of no importance this paper presents a variation of harsanyi s theorem in which the axioms are compatible with a concern for ex ante fairness the implied mathematical form for social welfare is a strictly quasi concave and quadratic function of individual utilities

intergenerational competitive equilibria under technological uncertainty and an exhaustible resource constraint abstract this paper presents a model of competitive intertemporal equilibrium in a finite horizon overlapping generations economy facing technological uncertainty and an exhaustible resource constraint individuals form rational expectations regarding future prices and economic conditions and income is redistributed from one generation to the next through government mandated lump sum transfers under uncertainty the relationship between resource price appreciation and the interest rate is mediated by consumers risk aversion with respect to consumption in alternative states of nature the intuitively appealing proposition that the expected resource price rises at the expected rate of interest holds only as a special case if future generations are taken to be state contingent in the sense that their composition depends on the states of nature prevailing when they are born then equilibria are generally pareto efficient but if future generations are state independent so that the set of individuals born at a given date is independent of the prevailing state of nature then equilibria may be inefficient because markets do not exist where successive generations may equilibrate their marginal rates of substitution across consumption in alternative contingent states such inefficiencies may be remedied through the implementation of appropriate intergenerational transfers an optimal intergenerational welfare distribution may be supported as a competitive equilibrium if the income transfer regime is properly selected and enforced the social optima that result for a simple version of the model under the maximin welfare criterion indicate that greater sacrifices are required on the part of the present generation when future generations are taken to be state contingent than when they are regarded as state independent this finding provides a possible explanation for the extreme risk aversion of conservationists with respect to the welfare of future generations

comparing futures a positional approach to population ethics abstract major questions in environmental economics concern choices about the future sensible decisions thus require rules for comparing the well being of potentially different sets of people in terms of both numbers and identities under different futures the central problem of normative population theory is that basic ethical principles that individually claim widespread acceptance yield unpalatable conclusions when combined no approach currently on offer is able to overcome all theoretical objections but decision making goes on and needs ethical guidance this paper proposes a practical approach to the welfare comparison of competing futures as a matter of expedience it accepts that some choices may be incommensurable and therefore unrankable but its defining characteristic is its recognition that the evaluation of well being is typically a momentary phenomenon dependent on an individual s position or reference frame a critical positional change arises from the very act of being brought into existence social welfare thus has to be continually re evaluated and the welfare basis for new decisions is subject to a ratchet effect although this approach abandons time consistency it does so without apology and since time flows in one direction without inconsistency in decision making

survey measures of family decision processes for econometric analysis of schooling decisions in this article we consider the collection of novel subjective data on family processes of schooling decisions in particular we review recent progress on survey measurement of expectations information and locus of decision of american families within the context of secondary schooling and we discuss possible future developments by providing concrete examples from recent exploratory efforts we argue that collection of data on adolescents and parents perceptions of the available school options and the application and admission rules their subjective expectations about short and long term consequences of alternative choices and their assessments of the locus of decision making within families could greatly enhance economic modeling and contribute to effective econometric analysis of schooling decisions jel c83 d19 d79 d83 d84 i21 i26 j24

the problem of population and growth a review of the literature from malthus to contemporary models of endogenous population and endogenous growth abstract this paper deals with the evolution of the literature on the problem of population and growth from the classical period to the recent literature on endogenous growth and development the problem concerns two distinct issues 1 how to explain the observed covariation of the levels and rates of growth of per capita income and population size over time and space and 2 how to improve the human condition represented by these variables through an accommodating social policy the evolution of the literature we survey is reflected by the progressive treatment of key variables as endogenous rather than exogenous to the growth process it is also reflected by a shift from the historical concern about population explosion and its implications for growth to the more recent concern about the association between growth and population implosion in many developed countries

the value of limited altruism abstract discounting the utilities of future people or giving smaller weights to groups other than one s own is often criticized on the grounds that the resulting objective function differs from the ethically appropriate one this paper investigates the consequences of changes in the discount rate and weights when they are moved toward the warranted ones using the utilitarian value function it is shown that except in restrictive special cases those moves do not necessarily lead to social improvements we suggest that limitations to altruism are better captured by maximizing the appropriate value function subject to lower bounds on some utilities journal of economic literature classification numbers d63 d71

aggregating sets of von neumann morgenstern utilities we analyze the aggregation problem without the assumption that individuals and society have fully determined and observable preferences more precisely we endow individuals ans society with sets of possible von neumann morgenstern utility functions over lotteries we generalize the classical neutrality assumption to this setting and characterize the class of neutral social welfare function this class turns out to be considerably broader for indeterminate than for determinate utilities where it basically reduces to utilitarianism in particular aggregation rules may differ by the relationship between individual and social indeterminacy we characterize several subclasses of neutral aggregation rules and show that utilitarian rules are those that yield the least indeterminate social utilities although they still fail to systematically yield a determinate social utility

optimal taxation critical level utilitarianism and economic growth abstract we analyze tax policies in an intertemporal economy with endogenous fertility under critical level utilitarianism both from a positive and a normative standpoint on the positive side we analyze the effects of a change in the tax on capital income and on fertility both separately and combined so as to keep the per capita public debt constant on the normative side we characterize the first and second best optimal tax structures for both exogenous and endogenous labor supply

college choice as a collective decision although the choice between colleges can be thought of as being made collectively by a family models of educational choice almost universally portray the decision as made by the student alone using a novel experimental method for identifying collective decision functions i find that students have more influence than parents over the decision but not exclusive control students care more than parents about classroom experience and future earnings ignoring the dual agent nature of the decision can weaken predictions and lead to poorly targeted policy designs jel i21 j24 d13

the effect of national culture on the choice of entry mode characteristics of national cultures have frequently been claimed to influence the selection of entry modes this article investigates this claim by developing a theoretical argument for why culture should influence the choice of entry two hypotheses are derived which relate culture to entry mode choice one focusing on the cultural distance between countries the other on attitudes towards uncertainty avoidance using a multinomial logit model and controlling for other effects the hypotheses are tested by analysing data on 228 entries into the united states market by acquisition wholly owned greenfield and joint venture empirical support for the effect of national culture on entry choice is found

social evaluations when populations differ in size assessments of social welfare do not usually take into account population sizes this can lead to serious social evaluation flaws particularly in contexts in which policies can affect demographic growth we develop in this paper a little known though ethically attractive approach to correcting the flaws of traditional social evaluations an approach that is sensitive to population sizes and that is based on critical level generalized utilitarianism clgu traditional clgu is extended by considering arbitrary orders of welfare dominance and ranges of poverty lines as well as values for the critical level of how much a life must be minimally worth to contribute to social welfare we apply these social evaluation methods to rank canada across 1976 1986 1996 and 2006 and to estimate normatively and statistically robust lower and upper bounds of critical levels over which these rankings can be made

some welfare theoretic implications of endogenous fertility this paper explores the implications of endogenous fertility for inter and intragenerational equity and for intergenerational efficiency considering equity requires social welfare criteria with respect to the issue of intragenerational equity 2 possible criteria in relation to the laissez faire solution are 1 total utility across generations and 2 average or per capita utility when population size is not fixed the 2 are not the same when fertility is not endogenous it is possible to consider noncoercive policies for achieving socially optimal population size or rate growth in general child allowances or taxes and subsidies to future consumption are sufficient to achieve the desired outcome with respect to within generation income distribution a system of child allowances and tax exemptions designed to alleviate poverty and reduce inequality may actually worsen the situation when both fertility and labor supply are endogenous discussing the issue of efficiency for members of the current generation does not require a social welfare function neither diminishing returns nor the existence of public goods unless financed by distortionary taxes leads to market failure from this point of view but the inability of parents to enforce transfers among their offspring or to bargain with the families of the potential spouses of their children may indeed lead to market failure finally the paper examines the implications for fertility of the inefficiency in an economy resulting from the absence of a capital market for transferring from present to future consumption in this case the welfare improving introduction of a capital market may increase the rate of growth of population when parents value children for themselves as well as a means of providing sustenance in old age

how much inequality can we explain a methodology and an application to the united states we develop two simple measures of how much inequality is explained by individual population characteristics or groups of characteristics analogous to r2 in regression analysis we investigate the measures empirical implementation using several alternative theoretically consistent approaches to inequality decomposition results are illustrated using us psid income data explaining the level of and trends in inequality is an intriguing topic but one that is often dependent on a researcher s particular approach to inequality measurement sometimes the approach is simply one that accords with intuition sometimes principles of applied welfare economics or statistical analysis are invoked the particular approach adopted is important the issue of the explanation of inequality is not just a matter of computational procedure but can significantly affect our understanding of economic inequality and can potentially guide the design of economic policy in this paper we develop new summary measures of explanation the income inequality literature s analogue of the r2 statistic used in regression analysis using an approach which pays particular attention to theoretically consistent methods for inequality decomposition and illustrate them using a specially cleaned set of us psid data an important example of the explanation issue that is relevant to current policy debate is the suggestion that personal attributes and labour market status are major determinants of interpersonal income differences formal economic models stress the role of labour market opportunities in the structure of the income distribution other types of analysis emphasise the importance of characteristics such as ethnicity age and gender it is commonly supposed that these factors explain a major part of observed income inequality and of changes in inequality in the case of the united states we show that this conjecture is empirically unfounded the supposed determinants of inequality in fact account for only a very small part of the actual inequality of broadly defined personal income

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

double majors one for me one for the parents i introduction at least a quarter of college students have more than one undergraduate major 2003 national survey of college graduates and the share of college students choosing more than one major is increasing at a very fast rate lewin 2002 it has been postulated that parents inadvertently drive their children to have more than one major that is students major in one field to satisfy their own interests and in another field that meets parents approval 1 other explanations for double majors include students majoring in one field associated with their professional specialty and another that reflects a very different interest like an engineering major who is also majoring in french or students hedging their chances in the labor market by preparing to work in more than field however evidence for all these explanations remains anecdotal gomstyn 2003 lewin 2002 and there is little systematic evidence on how students choose the composition of their double majors this article provides to the best of my knowledge the first direct evidence on how students conditional on having a double major choose the composition of majors 2 students choose a college major or pair of majors in order to influence the occurrence of choice specific outcomes that enter their utility function these outcomes include for example being able to successfully complete a field of study gaining parents approval finding a job upon graduation enjoying coursework or earnings at the job as these outcomes are uncertain at the time the student makes his choice he has a belief distribution of the probability for the occurrence of these outcomes conditional on each major in his choice set therefore a student uses both his preferences and subjective beliefs in choosing his college major s the researcher usually only observes the major s that the student chooses and has to make nonverifiable assumptions on expectations beliefs to infer the parameters of the utility function preferences the basic difficulty is that observed choices may be consistent with several combinations of expectations and preferences and the list of underlying assumptions on expectations may not be valid see manski 1993 for a discussion of this inference problem in the context of how students infer returns to schooling a solution to this identification problem is to use additional data on expectations manski 2004 and that is precisely what i do i survey a group of 69 northwestern university students pursuing double majors and elicit their subjective beliefs about major specific outcomes in my relatively homogenous sample there is substantial heterogeneity in beliefs for outcomes within a major as well as across majors indicative that there exists tremendous heterogeneity in beliefs in the population of college students analysis of beliefs for the same outcome across majors suggests that students have sensible beliefs about the occurrence of outcomes conditional on major for example the belief distribution of reconciling work and family at jobs available in literature and fine arts first order stochastically dominates the corresponding distribution in natural sciences in which most pre med students major comparison of beliefs of being able to graduate with a grade point average gpa of at least 3 5 and expected income at the age of 30 with objective measures reveals that students are aware of differences across majors i find that students believe that their parents are more likely to approve majors associated with high social status and returns in the labor market for example the mean belief of gaining parents approval for majoring in engineering is 0 87 on a scale of 0 1 compared with 0 59 for literature and fine arts the subjective data elicited from the students is employed directly in a structural model of double major choice 3 although i assume that students are forward looking and care about future outcomes when making their choices i do not have data needed to estimate a dynamic model

individual perceptions of the criminal justice system this paper empirically examines belief updating of the perceived probability of arrest and its criminal deterrence effects using two longitudinal data sources while beliefs about the probability of arrest are positively correlated with local official arrest rates they are unresponsive to information acquired from random individuals and local neighborhood conditions importantly perceptions respond to changes in an individual s criminal and arrest history young males who engage in crime without getting arrested revise their perceived probability of arrest downward while those who are arrested revise their probability upward estimates suggest that beliefs about the probability of arrest significantly deter crime jel k42

population ethics and the existence of value functions abstract this note provides a corrected version of a representation theorem in population ethics while it is true that the fixed population axioms continuity and weak pareto are sufficient for the existence of an ordering of population size representative utility pairs that can be used to rank social alternatives we show that in order to obtain the existence of a real valued representation continuity must be strengthened

efficient firm groups allocative efficiency in cooperative games abstract the concept of efficiency in groups postulates that a coalition of firms has to record a smaller distance toward the aggregate technology frontier compared with the sum of individual distances efficiency analysis either allocative or technical is defined with respect to cooperative firm game in order to provide operational distance functions the so called pseudo distance functions these pseudo distances belong to the core interior of the allocative firm game in other terms any given firm coalition may always improve its allocative efficiency we prove that such a result is impossible for technical efficiency i e the technical efficiency cannot increase for all possible coalitions

social welfare of alternative controlled price policies recent developments in social welfare analysis provide insights into the selection of price policies in the presen t paper a ces social welfare function and a weighted average of utilitarian and leximin rules are used to identify optimal producer prices in an economy where government is the price setter and agents are risk averse the analysis distinguishes between the interests of commercial producers peasant producers consumers and taxpayers a n application to zimbabwe indicates that a maize producer price in the low medium to medium portion of the historical range would be social ly optimal if egalitarian preferences are moderate this outcome is somewhat insensitive to group weighting schemes and to interpersonal utility correspondences copyright 1993 by mit press

celebrity endorsements in emerging markets align endorsers with brands or with consumers this paper investigates country of origin co effects as they relate to celebrity endorsements across multiple studies in emerging markets the authors show that consumers evaluations depend on the match between 1 celebrity co and consumer co termed consumer co fit and 2 celebrity co and brand co termed brand co fit if there is a trade off between consumer co fit and brand co fit the authors identify contingencies e g ethnocentrism levels that determine which type of co fit leads to higher evaluations furthermore the authors develop prescriptions for segmentation in emerging markets and specify when these prescriptions differ from those prescribed by prior international business research

the economic effects of climate change greenhouse gas emissions are fundamental both to the world s energy system and to its food production the production of co2 the predominant gas implicated in climate change is intrinsic to fossil fuel combustion specifically thermal energy is generated by breaking the chemical bonds in the carbohydrates oil coal and natural gas and oxidizing the components to co2 and h2o one cannot have cheap energy without carbon dioxide emissions similarly methane ch4 emissions an important greenhouse gas in its own right are necessary to prevent the build up of hydrogen in anaerobic digestion and decomposition one cannot have beef mutton dairy or rice without methane emissions climate change is the mother of all externalities larger more complex and more uncertain than any other environmental problem the sources of greenhouse gas emissions are more diffuse than any other environmental problem every company every farm every household emits some greenhouse gases the effects are similarly pervasive weather affects agriculture energy use health and many aspects of nature which in turn affects everything and everyone the causes and consequences of climate change are very diverse and those in low income countries who contribute least to climate change are most vulnerable to its effects climate change is also a long term problem some greenhouse gases have an atmospheric life time measured in tens of thousands of years the quantities of emissions involved are enormous in 2000 carbon dioxide emissions alone and excluding land use change were 24 billion metric tons of carbon dioxide tco2

an aspect of variable population poverty comparisons abstract this paper demonstrates that the property of replication invariance generally considered to be an innocuous requirement for the extension of fixed population poverty comparisons to variable population contexts is incompatible with other plausible variable and fixed population axioms this fact raises questions about what constitutes an appropriate headcount assessment of poverty in terms of whether one should focus on the proportion or the absolute numbers of the population in poverty this observation in turn has important implications for tracking poverty and setting targets for its reduction or elimination

the kaldor compensation test and rational choice abstract it is well known that the kaldor compensation test can be inconsistent in the sense that it leads to contradictory or cyclical recommendations in some situations this paper shows that there is a close relationship between the consistency of this test and the rationalizability of choices from given utility possibilities sets this observation suggests that if the kaldor test is consistent social decisions can be made using a social welfare ordering in the first place therefore the information assumptions embodied in some social welfare ordering have to be accepted if the kaldor test is to be applied consistently

the simple analytics of contraceptive social marketing abstract contraceptive social marketing csm programs have been advocated for the dissemination of contraceptives in developing countries this paper considers csm programs from a simple economic perspective it begins with a review of the major economic models of private fertility determinants and the associated private demand for contraceptives and then adds private contraceptive supply to obtain market equilibrium next inefficiencies due to negative externalities of added children and due to imperfect information and distributional concerns are considered finally this framework is utilized to point to lacunae in our knowledge of csm programs and their impact and to suggest some promising areas for research

the pay as you go pension system as fertility insurance and an enforcement device a paygo system may serve as insurance against not having children and as an enforcement device for ungrateful children who are unwilling to pay their parents a pension in fact the latter was bismarck s historic motive for introducing this system it is true that the paygo system reduces the investment in human capital but if it is run on a sufficiently small scale it may nevertheless bring about a welfare improvement if on the other hand the scale of the system is so large that parents bequeath some of their pensions to their children it is overdrawn and creates unnecessarily strong disincentives for human capital investment

inequality within and between families between family differences in expenditures and output reflect the effect of simultaneous increases in children s ability on the willingness of parents to transfer resources to them within family differences also reflect the attitudes of parents toward disparity among children in this paper we characterize the conditions on parents preferences that determine whether between family differences exceed within family differences for additive utility within family differences in expenditures always exceed between family differences this may also be true for the max min utility function if an increase in ability reduces the marginal utility of income within family differences in output utility or income can also exceed between family differences in this case the implication for income distribution is that equality is enhanced by a higher correlation of ability between brothers

a normative approach to industrial performance evaluation and concentration indices abstract in this paper we present a normative theory of industrial evaluation our framework provides a foundation for the notion of the equivalent number of equal sized firms which is an inverse measure of concentration from an axiomatic basis we develop a particular functional form for the evaluation of industry performance a cobb douglas function of the equivalent number of equal sized firms and total output

an econometric analysis of the old age security motive for childbearing a switching regression for birth interval lengths with endogenous switching is developed to test mead cains contention that parents fertility decisions arise from lexicographic preferences for old age security the model is estimated as a survival model using malaysian data assuming that contraceptors constitute the group of parents who have attained the minimal number of children with which they feel their old age support is secure strong support for cains concept of old age security as the principal interest of those parents who have not yet attained a sufficient number of children appears in these data however the income effect accompanying the provision of alternative means of old age support generates an ambiguous effect on subsequent fertility excerpt

unit consistent decomposable inequality measures this paper introduces a new axiom the unit consistency axiom into inequality measurement this new axiom requires the ordinal inequality rankings rather than the cardinal indices to be unaffected when incomes are expressed in different units i argue that unit consistency is an indispensable axiom for the measurement of income inequality when unit consistency is combined with decomposability i show that the unit consistent decomposable class of inequality measures is a two parameter extension of the one parameter generalized entropy class the extended class accommodates a variety of value judgments and includes different types of inequality measures

social criteria for evaluating population change an alternative to the blackorby donaldson criterion abstract an ethical objection is raised against the blackorby donaldson criterion of optimum population maximizing the sum total of utilities in excess of some critical level since it may disprefer a social state with more people and with more worthwhile lives however the criterion may serve as a practicably reasonable compromise between maximizing total and average utility nevertheless an alternative compromise the maximization of number dampened total utility is proposed that is free from the above objection

global cities and multinational enterprise location strategy we combine the concept of location derived by economic geographers with theories of the multinational enterprise mne and the liability of foreignness developed by international business scholars to examine the factors that propel mnes toward or away from global cities we argue that three distinctive characteristics of global cities global interconnectedness cosmopolitanism and abundance of advanced producer services help mnes overcome the costs of doing business abroad and we identify the contingencies under which these characteristics combine with firm attributes to exert their strongest influence consistent with these arguments our analysis of a large sample of mne location decisions using a multilevel multinomial model suggests not only that mnes have a strong propensity to locate within global cities but also that these choices are associated with a nuanced interplay of firm and subsidiary level factors including investment motives proprietary capabilities and business strategy our study provides important insights for international business scholars by shedding new light on mne location choices and also contributes to our understanding of economic geography by examining the heterogeneous strategies and capabilities of mnes the primary agents of economic globalization that shape the nature of global cities

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

the scope for taxation and public expenditure in an open economy in this survey of some central issues of tax and expenditure policy in an open economy we consider the implications for policy of free although not necessarily perfect international mobility of commodities capital and labour we examine the issues both from a positive and a normative point of view trying to identify both the incidence and welfare effects of international mobility one general conclusion is that tax distortions may increase in magnitude in comparison with a closed economy but they may also increase in kind as when otherwise neutral taxes become distortionary because of factor mobility

on the use of expectations data in estimating structural dynamic choice models despite the importance of expectations in models of decision behavior under uncertainty few empirical economists have made use of subjective expectations data in estimating such models assuming that expectations about future behavior accurately portray optimal future behavior conditional on current information it is shown that such data can provide similar information about the decision process as can data on current or retrospective behavior the value of self reported choice expectations is illustrated by using information on respondents expected future occupation in the estimation of a structural dynamic model of teacher career decisions under uncertainty

the demand for and return to education when education outcomes are uncertain this article treats education as a sequential choice that is made under uncertainty a simple model is used to explore the effects of ability high school preparation preferences for schooling the borrowing rate and ex post payoffs to college on the probability of various post secondary college outcomes and the ex ante return to starting college the model motivates an empirical method of accounting for uncertainty about educational outcomes and for nonlinearity in the relationship between years of education and earnings when estimating the expected return to the first year of college

escaping the poverty trap in a developing rural economy in this paper we examine the economic policies that might allow a developing rural economy to escape from the poverty trap characterized by a subsistence level of per capita consumption in the long run in our model where labour is combined to land available in fixed quantity to produce a homogeneous good saving could be made through only having children the number of which is an endogenous decision we provide conditions under which the economy runs into a poverty trap and proceed to analyse the relevant policies in this case we demonstrate that an escape from this poverty trap is possible through a suitable technology transfer or an appropriate child rearing tax but not with a foreign manufacturing sector which increases only temporarily the labour income in this rural economy jel classification j11 o11 o40 se sortir du piege de la pauvrete dans une economie rurale en developpement dans cet article nous analysons les politiques qui peuvent permettre a une economie rurale en developpement de sortir d un piege de pauvrete caracterise par un niveau de consommation de subsistance dans notre modele pour lequel le travail est combinea la terre afin de produire un bien homogene l epargne ne peut se faire qu a travers les enfants dont le nombre est une variable de decision endogene nous decrivons les conditions sous lesquelles l economie converge vers un piege de pauvrete et analysons les politiques appropriees a adopter dans une telle situation nous demontrons que la sortie du piege de pauvrete peut etre accomplie gr ce a un transfert technologique approprie ou a travers une taxe sur les enfants par contre l introduction d un secteur manufacturier controle par des etrangers ne fait qu accroitre temporairement le revenu per capita

what we talk about when we talk about global mindset managerial cognition in multinational corporations recent developments in the global economy and in multinational corporations have placed significant emphasis on the cognitive orientations of managers giving rise to a number of concepts such as global mindset that are presumed to be associated with the effective management of multinational corporations this paper reviews the literature on global mindset and clarifies some of the conceptual confusion surrounding the construct we identify common themes across writers suggesting that the majority of studies fall into one of three research perspectives cultural strategic and multidimensional we also identify two constructs from the social sciences cosmopolitanism and cognitive complexity that underlie the perspectives found in the literature we then use these two constructs to develop an integrative theoretical framework of global mindset we then provide a critical assessment of the field of global mindset and suggest directions for future theoretical and empirical research

population size individual choice and social optima optimal population size when fertility is endogenous is considered in relation to two social welfare criteria a benthamite and a millian and in relation to purely individualistic maximization of utility in the current generation the authors show that a tax subsidy scheme involving child allowances and subsidies to future generation consumption can be found to support a social optimum through individual choice a general proof that the optimal population size according to the benthamite criterion is always larger than that given by the millian criterion is presented but it is shown that no general conclusions about the size of the population under laissez faire are possible excerpt

jeux sans frontieres tax competition and tax coordination when countries differ in size closer international integration is putting increasing pressure on existing national tax structures this paper uses a simple two country model to address a range of consequent policy concerns focusing particularly on the role of country size differences in size exacerbate the inefficiency from noncooperative behavior harming both countries the smaller country loses from harmonization to any tax rate between those set in the noncooperative equilibrium but both countries gain from the imposition of a minimum tax anywhere in that range the fully optimal response to freer cross border trade however may be to do nothing jel h20 h77

the equivalence between destination and non reciprocal restricted origin tax regimes it is well known that destination and reciprocal restricted origin tax regimes are only equivalent under very stringent conditions an alternative nonreciprocal restricted origin regime is proposed and then shown to be equivalent to the destination regime under a wide set of conditions including imperfect competition and transport costs the policy implications of the result for the european community are discussed copyright 1994 by the editors of the scandinavian journal of economics

pigs and guinea pigs a note on the ethics of animal exploitation discussions of the morality of animal exploitation must deal with the fact that these activities result in animal populations that would not otherwise exist in this paper simple economic models of animal using food production and research are combined with explicit ethical criteria that are sensitive to animal well being and numbers the authors show that when animal exploitation is morally acceptable lack of regulation results in too many food animals and research that is too animal intensive in addition nonmarket control through bills of rights for farm animals and research practice standards is necessary for ethical optimality copyright 1992 by royal economic society
