beyond gdp the quest for a measure of social welfare this paper critically examines the various approaches to the measurement of individual well being and social welfare that have been considered for the construction of alternatives to gdp special attention is devoted to recent developments in the analysis of sustainability in the study of happiness in the theory of social choice and fair allocation and in the capability approach it is suggested in the conclusion that although convergence toward a consensual approach is not impossible for the moment not one but three alternatives to gdp are worth developing jel i31 e23 e01

de gustibus non est taxandum heterogeneity in preferences and optimal redistribution abstract the prominent but unproven intuition that preference heterogeneity reduces redistribution in a standard optimal tax model is shown to hold under the plausible condition that the distribution of preferences for consumption relative to leisure rises in terms of first order stochastic dominance with income given familiar functional form assumptions on utility and the distributions of ability and preferences a simple statistic for the effect of preference heterogeneity on marginal tax rates is derived numerical simulations and suggestive empirical evidence demonstrate the link between this potentially measurable statistic and the quantitative implications of preference heterogeneity for policy

revealed social preferences of dutch political parties we measure the redistributive preferences of dutch political parties using unique detailed information from their election proposals by employing the inverse optimal tax method we calculate the political weights across the income distribution for each political party we find that all dutch political parties give a higher political weight to middle incomes than to the poor moreover the political weights of the rich are close to zero furthermore we detect a strong political status quo bias as the political weights of all political parties hardly deviate from the weights implied by the pre existing tax system we argue that political economy considerations are key in understanding these results

opening the black box of agglomeration economies for measuring cities competitiveness through international firm networks the ability of cities to operate in global networks is usually measured according to their central position within multinational firm linkages these measures are often used at the interurban level and neglect the intraurban processes of multiplier effects the present study demonstrates that this affects the measurement of city centrality in business networks intraurban capabilities of interaction are considered in the measurement of interurban indices the study is based on hypothetical networks at a micro level between long range links and it mobilises processes as agglomeration economies social capital developments and transaction costs these processes at the intraurban level strengthen the efficiency of interurban linkages it is suggested that the indices used to measure city centrality should include these local effects applied to a small sample of six firm networks the methodology shows advantages for emerging large metropolises but insufficient local effects for specialised clusters the mu

seeking sustainability discourses with q methodology abstract this paper outlines the potential benefit of q methodology for the study of environmental issues within ecological economics based on research into lets local employment and trading systems in the united kingdom q methodology is a qualitative but statistical approach to enable the discovery of a variety of discourses concerning how individuals understand their behaviour and how they understand the social and environmental worlds in which they live q methodology thus has the capacity to allow a more effective form of policy making and implementation process the paper introduces some of the basic tenets of q methodology illustrates these with results drawn from the study mentioned above and concludes by indicating the potential this methodology holds for ecological economics research

popular acceptance of inequality due to innate brute luck and support for classical benefit based taxation abstract u s survey respondents views on distributive justice differ in two specific related ways from what is conventionally assumed in modern optimal tax research when expressing their preferences over allocations in stylized hypothetical scenarios meant to isolate key features of the tax problem a large share of respondents resist the full equalization of unequal outcomes due to innate brute luck that standard analyses recommend a similar share prefer a classical benefit based logic for taxes over the conventional logic of diminishing marginal social welfare moreover these two views are linked respondents who more strongly resist equalization are more likely to prefer the classical benefit based principle though the amazon mechanical turk survey population is not a representative sample of the u s population robustness of these results across demographic traits and political views suggests that a large share of the american public holds views inconsistent with standard welfarist objectives

positive and normative judgments implicit in u s tax policy and the costs of unequal growth and recessions calculating the welfare implications of changes to economic policy or shocks requires economists to decide on a normative criterion one approach is to elicit the relevant moral criteria from real world policy choices converting a normative decision into a positive inference as in the recent surge of inverse optimum research we find that capitalizing on the potential of this approach is not as straightforward as we might hope we perform the inverse optimum inference on u s tax policy from 1979 through 2010 and argue that the results either undermine the normative relevance of the approach or challenge conventional assumptions upon which economists routinely rely when performing welfare evaluations

nonmarket transfers and altruism abstract we examine altruistically motivated consumption transfers in an effort to account for nonmarket transfers we find that altruistic linkages lead to autonomous negotiation free transfers and that such transfers positively respond to stronger altruism we also find that given fairly natural assumptions concerning the altruism parameters mutual altruism does not necessarily result in group social harmony even though its rise narrows the conflict range in spite of enhanced transfers prompted by such a rise both parties may end up worse off these results help explain why in some social environments a shift toward market oriented transfers and exchanges may be quicker than in others as the disadvantages decline in utility associated with intragroup altruistic linkages outweigh the advantages

the experience of some oecd economies on tax smoothing observed random walk behaviour of a tax rate does not necessarily support the tax smoothing hypothesis though the latter implies the former this article presents a direct test of tax smoothing by showing that if the tax smoothing hypothesis holds then the future tax rate should cointegrate with the current permanent government expenditure rate even though the tax rate is a random walk this test is a direct and robust test of a number of random walk models available in the literature this procedure also enables us to differentiate among strong tax smoothing weak tax smoothing and no tax smoothing all of which are consistent with the random walk behaviour of a tax rate application of this test to australia canada italy japan the netherlands new zealand the uk and the us show evidence in support of weak forms of tax smoothing

is it fair to make work pay the design of the income transfer program for the lower incomes is a hot issue in current public policy debate should we stick to a generous welfare state with a sizeable basic income but high marginal tax rates for the lower incomes and thus little incentives to work or should we make work pay by subsidizing the work of low earners but possibly at the cost of a smaller safety net we think it is difficult to answer this question without making clear what individuals are held responsible for and what not first we present a new fair allocation coined a pareto efficient and shared resources equivalent pese allocation which compensates for different productive skills but not for different tastes for working we also characterize a fair social ordering which rationalizes the pese allocation second we illustrate the optimal second best allocation in a discrete stiglitz 1982 1987 economy the question whether we should have subsidies for the low earners or not crucially depends on whether the low skilled have a strictly positive or zero skill third we simulate fair taxes for a sample of belgian singles our simulation results suggest that making work pay policies can be optimal according to our fairness criterion but only in the unreasonable case in which none of the unemployed are ever willing to work

value based adaptation to climate change and divergent developmentalisms in turkish agriculture there is an increased recognition and attention on human values with respect to their role in shaping climate change adaptation policies furthermore as the recent literature suggests values held by policy actors are centrally located in the debates linking adaptation to development however different values tend to give way to diverging adaptation policy preferences which often appear as a dichotomy of adjustment incremental change versus transformation this study enquires the assumptions and values in adaptation policy by using q methodology and advances value based approach to adaptation policy with an empirical case from turkey a developing country with key vulnerabilities in its agricultural system by exploring the narratives of 29 policy actors who participated in the making of turkey s climate change adaptation strategy the analysis suggests that assumptions regarding an economic growth driven development agenda often shape adaptation concerns further analysis of the 4 emerging discourses productivism techno managerialism eco localism and authoritarianism suggests that while discourses agree that the ultimate goal of adaptation is safeguarding a developmentalist vision in agriculture they differ on the means and agents for reaching this goal i argue that this divergence can enhance the transformative potential of adaptation by bringing how for whom and why questions back to policymaking

redistribution and inequality in a heterogeneous society this paper analyses how income redistribution affects inequality in a society in which individuals differ in their earning abilities and their preferences for consumption and leisure after discussing the shortcomings of various standard approaches i measure inequality in such a heterogeneous society by the inequality in individuals so called equivalent wages this approach suggests that redistribution tends to reduce inequality by transferring income from high ability to low ability individuals but to increase inequality by transferring income from consumption loving to leisure loving individuals these countervailing effects lead in all my simulations to a u shaped relationship between redistribution and inequality

agriculture s environmental externalities dea evidence for french agriculture the existence of persistent technical inefficiency offers the opportunity for a free lunch not typically implied by the neoclassical theory of the firm when external effects are related to the use of particular inputs reduction of persistent technically inefficient levels of input use represents a means of reducing external impacts an important example is found in agriculture where substantial environmental impacts are generated by particular inputs within this context this paper considers the usefulness of data envelopment analysis dea for estimation of potential input reductions and assessment of potential reductions of environmental impacts of agricultural inputs an application for french cereal production provides estimates that indicate that substantial potential exists for reduction of input use and environmental impacts

industrial location behaviour and regional restructuring within the fifth tiger economy evidence from the thai electronics industry the paper investigates the location behaviour of firms in the electronics industry in thailand our approach is to use a logit model in order to analyse how the characteristics of the firms and the regions are related to the location decisions of firms in these sectors the logit results throw some light on the question of the nature of agglomeration behaviour in a developing economy in which the national spatial industrial structure is dominated by a single primal city our conclusions provide tentative support for a product cycle argument of industrial concentration and dispersion

optimal demogrants with imperfect tagging abstract this paper considers optimal taxation of income when some individuals are imperfectly tagged as disabled it proves that under very general conditions these individuals should receive a larger demogrant if leisure is a normal good

monopoly provision of product quality and warranties an exploration in the theory of multi dimensional screening we address the monopoly problem of designing and pricing a product line of goods distinguished by different quality and warranty levels consumers vary in their evaluations of these attributes so that the problem is one of screening it is sufficiently complex that the local approach commonly used does not work instead we use new techniques for dealing with incentive constraints between nonadjacent consumer types these techniques allow us to characterize optimal allocations that may not be monotonic in particular although the more eager types of buyer do pay higher prices and yield the monopoly higher profit they may receive lower quality or lower warranty coverage we find preference restrictions that restore monotonicity concave risk tolerance implies that warranty coverage increases in type and constant absolute risk aversion implies that quality increases in type

resource egalitarianism with a dash of efficiency abstract we study the problem of defining inequality averse social orderings over allocations of commodities when individuals have different preferences we formulate a notion of egalitarianism based on the axiom that any dominance between consumption bundles should be reduced this dominance aversion requirement is compatible with consensus a version of the pareto principle saying that an allocation y is better than x whenever everybody finds that everyone s bundle at y is better than at x we characterize a family of multidimensional leximin orderings satisfying dominance aversion and consensus

revisiting the classical view of benefit based taxation this paper explores how the persistently popular classical logic of bene t based taxation in which an individual s bene t from public goods is tied to his or her income earning ability can be incorporated into modern optimal tax theory if lindahl s methods are applied to that view of bene ts rst best optimal policy can be characterized analytically as depending on a few potentially estimable statistics in particular the coe cient of complementarity between public goods and innate talent constrained optimal policy with a pareto e cient objective that strikes a balance controlled by a single parameter between this principle and the familiar utilitarian criterion can be simulated using conventional constraints and methods a wide range of optimal policy outcomes can result including those that match well several features of existing policies to the extent that such an objective re ects the mixed normative reasoning behind prevailing

welfare egalitarianism in non rival environments we study equity in economies where a set of agents commonly own a technology producing a non rival good from their private contributions a social ordering function associates to each economy a complete ranking of the allocations we build social ordering functions satisfying the property that individual welfare levels exceeding a legitimate upper bound should be reduced combining that property with efficiency and robustness properties with respect to changes in the set of agents we obtain a kind of welfare egalitarianism based on a constructed numerical representation of individual preferences

the rise fall and rise again of industrial location theory m ccann p and sheppard s 2003 the rise fall and rise again of industrial location theory reg studies 37 649 663 in this paper we will argue that new academic fashions new international institutional arrangements new communications technology and new developments in data availability have all renewed the need for a redevelopment of analytical industrial location theory our paper will argue that the microeconomic foundations of industrial location theory must now be reconsidered in particular the methodological basis of traditional industrial location models needs to be reconciled with recent models of clustering the new economic geography literature and also more aggregate systemic levels of analysis we will argue that in order to do this it is necessary first to specify the transactions cost assumptions underlying these various approaches second to adopt broader definitions of spatial transactions costs and third to incorporate environmental characteristics within an orthodox loca

optimal incentives for labor force participation abstract optimal taxation is analyzed under a rawlsian criterion in an economy where the only decision of the agents is to participate or not to the labor force the model allows for heterogeneity both in the agent s productivities and aversions to work at a first best optimal schedule the marginal agent who decides to work pockets all of her productivity while being just compensated for her work aversion when the planner does not observe work aversion financial compensation for work is lower than productivity theory puts little restrictions on the shape of the optimal tax schedules the usual first order conditions involving the elasticities of participation only apply for sufficiently regular economies we qualitatively show how the optimal incentive schemes depend on the underlying structure of the preferences 100 marginal tax rates or subsidies to work are related to specific features of the economies

approaches to inequality of opportunity principles measures and evidence we put together the dierent conceptual issues involved in measuring inequality of opportunity discuss how these concepts have been translated into computable measures and point out the problems and choices researchers face when implementing these measures our analysis identies and suggests several new possibilities to measure inequality of opportunity the relevance of the conceptual issues and modelling choices are illustrated with ndings from the empirical literature on income inequality of opportunity

large indivisibles an analysis with respect to price equilibrium and fairness an exchange economy is considered in which there are a finite number of individuals the same number of indivisibles and a fixed amount of a divisible good each individual consumes exactly one of the indivisibles and a certain quantity of the divisible good the existence of prices corresponding to pareto efficient allocations is proved it is also shown that this economy possesses fair allocations income fair allocations coalition fair allocations and pareto efficient egalitarian equivalent allocations in this study the effect of including large indivisibles in an exchange economy will be analyzed the analysis will be carried out with respect to the existence of price equilibrium and with respect to the existence of different forms of fairness the economy consists of a finite number of individuals the same number of indivisibles and a fixed amount of a divisible good it is assumed that each individual consumes exactly one of the indivisibles and some quantity of the divisible good we may interpret the indivisibles as being professions or houses the relationship between price equilibrium and a pareto efficient allocation is well known and proved in a number of cases under different assumptions about preferences and commodities for a standard economy see e g debreu 5 in case of nonconvexities which may also describe a certain type of indivisibility we may have an exact relationship in economies with a continuum of individuals see e g hildenbrand 11 but otherwise an approximate relationship obtains the degree of approximation depends on the degree of nonconvexities in preferences and not on the number of individuals see e g arrow and hahn 1 we will prove the existence of prices characterizing a pareto efficient allocation in a case where the indivisibles play an essential role and where approximate results would be too approximate the indivisibles may be considered large for the individual compared to his total consumption the theory of fairness has developed considerably during the seventies different kinds of concepts of fairness have been introduced and analyzed see daniel 41 foley 81 pazner and schmeidler 121 and schmeidler and vind 141 among others normally these authors have considered models with divisible goods or an infinite number of individuals for exchange economies the existence of fair allocations an envy free and pareto efficient allocation has been proved in

public goods and private interests understanding non residential demand for green power this article presents the results of the first large scale mail survey of non residential green power customers in the united states the survey explored the motivations attitudes and experiences of 464 business non profit and public sectorcustomers that have voluntarily opted to purchase and frequently pay a premium for renewable electricity results of this study should be of value to marketers interested in targeting these customer segments to policymakers interested in fostering and understanding non residential demand for green power and to academics pondering the motivations for firms to engage in such voluntary environmental initiatives

fair production and allocation of an excludable nonrival good we study fairness in economies with one private good and one partially excludable nonrival good a social ordering function determines for each profile of preferences an ordering of all conceivable allocations we propose the following free lunch aversion condition if the private good contributions of two agents consuming the same quantity of the nonrival good have opposite signs reducing that gap improves social welfare this condition combined with the more standard requirements of unanimous indifference and responsiveness delivers a form of welfare egalitarianism in which an agent s welfare at an allocation is measured by the quantity of the nonrival good that consumed at no cost would leave her indifferent to the bundle she is assigned

social orderings for the assignment of indivisible objects in the assignment problem of indivisible objects with money we study social ordering functions which satisfy the requirement that social orderings should be independent of changes in preferences over infeasible bundles we combine this axiom with efficiency consistency and equity axioms our result is that the only social ordering function satisfying those axioms is the leximin function in money utility

a comparison of optimal tax policies when compensation or responsibility matter this paper examines optimal redistribution in a model with high and low skilled individuals with heterogeneous tastes for labor we compare the extent to which optimal policies based on different normative criteria obey the principles of compensation for differential skills and responsibility for preferences for labor when labor supply is along the extensive margin with heterogeneity in skills and preferences traditional welfarist criteria including utilitarianism present unappealing policy recommendations in some scenarios as they fail to take compensation and responsibility issues into account criteria from the social choice literature perform better in this regard in first and second best more importantly these equality of opportunity criteria push the second best policy away from an earned income tax credit and in the direction of a negative income tax

rethinking the economics of location and agglomeration fundamental problems exist with the classical characterisation of agglomeration economies since such definitions do not reflect the various cost issues on which firms may wish to economise a lack of understanding of the relationship between the notions of market hierarchies and locational behaviour leads to confusion not only in applied economic interpretation but more fundamentally in the construction of theoretical location models in particular neo classical location theory can be shown to be crucially flawed as a basis for spatial analysis this paper therefore attempts to provide an alternative definition of the various types of agglomeration economies such that the various strands of economic theory might be used in a more rigorous manner in the discussion of spatial increasing returns

voting for redistribution under desert sensitive altruism we endow individuals that differ in skill levels and tastes for working with altruistic preferences for redistribution in a voting model where a unidimensional redistributive parameter is chosen by majority voting in a direct democracy when altruistic preferences are desert sensitive i e when there is a reluctance to redistribute from the hard working to the lazy we show that lower levels of redistribution emerge in political equilibrium we provide empirical evidence based on the issp 1992 dataset that preferences for redistribution are not purely selfish and that desert sensitive motivations play a significant role we estimate that preferences for redistribution are significantly more desert sensitive in the us than in europe we believe that differences in desert sensitive preferences for redistribution help explain the different social contracts that prevail in both continents

fair income tax fairness is a key concept in redistribution issues in this paper we study how particular requirements of fairness can shed light on the design of the optimal income tax schedule we consider a population of heterogeneous individuals or households who differ in two respects first they have unequal skills and therefore unequal earning abilities second they differ in terms of their preferences about consumption and leisure and as a consequence typically make different labour time choices both kinds of differences generate income inequalities we study how to justify and compute a redistribution income tax in this context redistribution through an income tax usually entails distortions of incentives but the resulting efficiency loss has to be weighed against potential improvements in the fairness of the distribution of resources we address this efficiency equity trade off here by constructing social preferences which obey the standard pareto principle in addition to fairness conditions

is commodity taxation unfair abstract in a model where agents have unequal skills and heterogeneous preferences about consumption goods and leisure this paper studies how to combine commodity taxes and non linear income tax it proposes a particular social welfare function on the basis of fairness principles it then derives a simple criterion for evaluating the social welfare consequences of various tax schedules under the proposed approach the optimal tax should have no commodity tax for some range of consumptions and income redistribution would feature high subsidies to the working poor it is also shown that even when the income tax fails to be optimal commodity taxes may not improve social welfare

two criteria for social decisions abstract this paper studies the ethical underpinnings of two social criteria which are prominent in the literature dealing with the problem of evaluating allocations of several consumption goods in a population with heterogenous preferences the pazner schmeidler criterion pazner schmeidler egalitarian equivalent allocations a new concept of economic equity quart j econ 92 1978 671 687 and the egalitarian walras criterion fleurbaey and maniquet utilitarianism versus fairness in welfare economics in m salles j a weymark eds justice political liberalism and utilitarianism themes from harsanyi and rawls cambridge university press cambridge 1996 forthcoming are prima facie quite different but it is shown here that these criteria are related to close variants of the fairness condition that an allocation is better when every individual bundle in it dominates the average consumption in another allocation in addition the results suggest that the pazner schmeidler criterion can be viewed as the best extension of the walrasian criterion to non convex economies

on the non existence of envy free and egalitarian equivalent allocations in economies with indivisibilities abstract we consider economies with indivisible goods houses jobs and one infinitely divisible good an allocation is envy free if no agent prefers someone else s consumption to his own an allocation is egalitarian equivalent if there is a reference bundle that every agent finds indifferent to his consumption we show that in such economies there may be no allocation that is both egalitarian equivalent and envy free

tax structure and government expenditures with tax equity concerns abstract we augment a standard tax model by concerns about tax equity people get upset when labour is taxed more heavily than capital even the slightest concern for tax equity invalidates the common tenet that capital remains tax exempt in small open economies this holds for exogenous as well as for endogenous government expenditures and irrespective of whether concerns with tax equity only cause emotional discomfort or also impact on work incentives if concerns with tax equity get more intense the economy may choose higher taxes on labour and move to the downward sloped part of its laffer curve for endogenous government spending stronger concerns with tax equity may lead to a larger size of the public sector

equality of opportunity theory and measurement during the last third of the twentieth century political philosophers actively debated about the content of distributive justice the ruling ethical view of utilitarianism was challenged by various versions of equality of opportunities economists formulated several ways of modeling these ideas focusing upon how individuals are placed with respect to opportunities for achieving various outcomes and what compensation is due to individuals with truncated opportunities after presenting a review of the main philosophical ideas section 2 we turn to economic models sections 3 and 4 we propose a reformulation of the definition of economic development replacing the utilitarian measure of gdp per capita with a measure of the degree to which opportunities for income acquisition in a nation have been equalized finally we discuss issues that the econometrician faces in measuring inequality of opportunity briefly review the empirical literature section 6 and conclude section 7

prosocial behavior private contributions to agriculture s impact on the environment private provision of public environmental benefits is considered with a theory of prosocial behavior that elaborates the roles of nonhedonistic values held by agents as well as the functional interaction between private good and public good production processes the theory also identifies the conditions under which public environmental goods will be privately supplied and motivates an empirical approach models of environmental effort in agriculture are estimated based on a survey of u s field crop farmers results confirm the role of hedonistic motivation of environmental effort and provide very weak evidence of a role of nonhedonistic values

mean variance analysis of supply chains under wholesale pricing and profit sharing schemes in this paper we explore the use of a wholesale pricing and profit sharing scheme wpps for coordinating supply chains under the mean variance mv decision framework we first analytically establish the necessary and sufficient conditions for coordinating the centralized supply chain by wpss we then show that there exists a unique equilibrium of the stackelberg game with wpps in the decentralized case after that we discuss the information asymmetric case in which the retailer can be benefited by pretending to be more risk averse finally we propose a new measure for the manufacturer to prevent this cheating from happening insights are generated

a reexamination of the optimal nonlinear income tax abstract this paper investigates mirrlees model of optimal income taxation it provides a concrete example of utility and density functions for which the solution to the usual first order model is not implementable i e and example where the first order approach does not work adding second order conditions leads to an extended model and to implementable solutions if these conditions are binding one gets a kink in the optimal net income schedule and bunching of individuals occurs the properties of an optimal nonlinear income tax are reexamined within the extended model

landownership and the adoption of minimum tillage full owner operators and landowners with small holdings have lower minimum tillage adoption rates on cultivated cropland than do other landownership groups after accounting for land quality and regional location nonfamily corporate structure does not significantly influence the adoption decision these conclusions about minimum tillage adoption were obtained from a logit model using 7 649 cultivated cropland observations from across the united states this study indicates that small operating size poses more of an obstacle to minimum tillage adoption than does separation of ownership from farm operation

optimal taxation in the extensive model abstract we study optimal taxation under extensive preferences the agents utilities are constant for positive actions up to a maximal productivity level utilities may be discontinuous at the origin reflecting fixed costs of participation allowing for general distributions of work opportunity costs and productivity and for income effects we characterize optimal incentive compatible tax schedules we then give sufficient conditions for society to desire redistribution when these conditions hold upward distortions of the financial incentives to work can only occur for low skilled workers such upwards distortions are indeed always present when the fixed participation costs are pecuniary

should the good and the selfish be taxed differently in this paper we consider an environment where individual actions have externalities and two types of agents exist agents with social preferences the good and selfish agents selfish agents have pay off functions that do not take into account social welfare the pay off of an agent is a linear combination of social welfare and the pay off of a selfish agent we demonstrate that the corrective tax rates that maximize social welfare do not depend on the degree of social preferences hence the good and the selfish should not be taxed differently

optimal redistribution with unobservable disability welfarist versus non welfarist social objectives this paper examines the optimal non linear income and commodity tax when the same labor disutility can receive two alternative interpretations taste for leisure and disability but the disability is not readily observable we compare the optimal policy under alternative social objectives welfarist and non welfarist and conclude that the non welfarist objective in which the planner gives a higher weight to the disutility of labour of the disabled individuals is the only reasonable specification it has some foundation in the theory of responsability further unlike the other specifications it yields an optimal solution that may involve a lower labour supply requirement from disabled individuals

farmer risk assessment for voluntary insecticide reduction abstract we develop a theoretical basis for voluntary reduction in insecticide use and quantify the subjective value farmers place on reducing environmental risk the indirect utility model is used to quantify the acceptable financial cost of eliminating one insecticide application in return for avoidance of moderate risk to the environment the mean valuation in illinois iowa nebraska and ohio usa is 8 25 per acre acceptable yield loss increases with importance of environmental goods with formal education and with farming experience valuation increases with total expenditure on insecticides up to 89 per acre decomposition of the tobit model used in estimation indicates that voluntary programs should target intensification rather than extensification of participation to maximize effectiveness

developing a social perspective to farm performance analysis abstract this paper examines how traditional farm productivity analysis can be extended to produce a performance measure from the perspective of society a biophysical model is used to measure inputs from the environment which are combined with conventional marketed inputs to develop an environmentally sensitive malmquist productivity index to determine social productivity growth data envelopment analysis dea is used to analyze data collected from selected farms in south east australia and includes a measure of leaching and run off as a proxy measure of the impact the application of fertilizers has on ground and surface water the results show measured productivity growth increases for some farms and decreases for others when environmental factors are considered

the possibility of social choice the subject of social choice includes within its capacious frame various problems with the common feature of relating social judgments and group decisions to the views and interests of the individuals who make up the society or the group some challenges and foundational problems faced by social choice theory as a discipline are discussed social choice theory is a subject in which formal and mathematical techniques have been very extensively used voting based procedures are entirely natural for some kinds of social choice problems such as elections referendums or committee decisions they are however altogether unsuitable for many other problems of social choice impossibility results in social choice theory led by the pioneering work of arrow 1951 have often been interpreted as being thoroughly destructive of the possibility of reasoned and democratic social choice including welfare economics that view is argued against

liberal egalitarianism and the harm principle this paper analyses the implications of classical liberal and libertarian approaches for distributive justice in the context of social welfare orderings an axiom capturing a liberal non interfering view of society named the weak harm principle is studied whose roots can be traced back to john stuart mill s essay on liberty it is shown that liberal views of individual autonomy and freedom can provide consistent foundations for social welfare judgements in both the finite and the infinite context in particular a liberal non interfering approach can help to adjudicate some fundamental distributive issues relative to intergenerational justice however a surprisingly strong and general relation is established between liberal views of individual autonomy and non interference and egalitarian principles in the rawlsian tradition

multiproduct nonlinear pricing typically work on mechanism design has assumed that all private information can be captured in a single scalar variable this paper explores one way in which this assumption can be relaxed in the context of the multiproduct nonlinear pricing problem it is shown that the firm will choose to exclude some low value consumers from all markets a class of cases that allow explicit solution is derived by making use of a multivariate form of integration by parts in such cases the optimal tariff is cost based

measuring unfair in equality abstract this paper shows one way of generalizing the standard framework of inequality measurement to allow for a distinction between fair and unfair inequalities we introduce the unfairness lorenz curve and the unfairness gini which are generalizations of the standard versions of the lorenz curve and the gini with this more general framework in place we study the implications of responsibility sensitive theories of justice for the evaluation of the income distribution in norway from 1986 to 2005 we find that both the pre tax and the post tax income distributions have become less fair in norway even though the standard gini for the pre tax income distribution has decreased in the same period two trends explain this development the increase in income share of the top percentile and the change in the situation of females in the labor market the concentration of income at the top of the distribution contributes both to increased unfairness and increased inequality whereas the increase in females working hours and level of education primarily contributes to a reduction in inequality thus the latter effect dominates for the standard gini and the former effect for the unfairness gini furthermore we find that the increase in post tax unfairness is even larger than the increase in pre tax unfairness which shows that the tax system in norway contributes less to eliminating unfairness in 2005 than in 1986

sharing the cost of a public good an incentive constrained axiomatic approach we study the problem of provision and cost sharing of a public good in large economies where exclusion complete or partial is possible we search for incentive constrained efficient allocation rules that display fairness properties population monotonicity says that an increase in population should not be detrimental to anyone demand monotonicity states that an increase in the demand for the public good in the sense of a first order stochastic dominance shift in the distribution of preferences should not be detrimental to any agent whose preferences remain unchanged under suitable domain restrictions we give an explicit characterization of all incentive constrained efficient allocation rules we then show that there exists a unique incentive constrained efficient and demand monotonic allocation rule the so called serial rule in the binary public good case the serial rule is also the only incentive constrained efficient and population monotonic rule

consumer s surplus without apology the purpose of this paper is to settle the controversy surrounding consumer s surplus and by so doing to validate its use as a tool of welfare economics i will show that observed consumer s surplus can be rigorously utilized to estimate the unobservable compensating and equivalent variations the correct theoretical measures of the welfare impact of changes in prices and income on an individual i derive precise upper and lower bounds on the percentage errors of approximating the compensating and equivalent variations with consumer s surplus these bounds can be explicitly calculated from observable demand data and it is clear that in most applications the error of approximation will be very small in fact the error will often be overshadowed by the errors involved in estimating the demand curve the results in no way depend upon arguments about the constancy of the marginal utility of income consequently this paper supplies specific empirical criteria which can replace the apologetic caveats frequently employed by those who presently apply consumer s surplus moreover the results imply that consumer s surplus is usually a very good approximation to the appropriate welfare measures to preview below i establish the validity of these rules of thumb for a

the promise of positive optimal taxation normative diversity and a role for equal sacrifice abstract a prominent assumption in modern optimal tax research is that the objective of taxation is utilitarian i present new survey evidence that most people reject this assumption s implications for several prominent features of tax policy instead preferring tax policies based at least in part on a classic alternative objective the principle of equal sacrifice i generalize the standard model to accommodate this preference for a mixed objective proposing a method by which to make disparate criteria commensurable while respecting pareto efficiency then i show that optimal policy in this generalized model calibrated to the survey evidence and u s microdata is capable of quantitatively matching several features of existing tax policy that are incompatible in the conventional model but widely endorsed in the survey and reality including the coexistence of substantial redistribution and limited tagging together these findings demonstrate the potential of a positive theory of optimal taxation

efficiency first or equity first two principles and rationality of social choice abstract this paper formalizes two different principles to socially rank allocations under efficiency equity trade off the efficiency first social preference relation ranks an allocation x higher than an allocation y if and only if i x is pareto superior to y or ii x and y are pareto noncomparable and x is equity superior to y the equity first social preference relation reverses the order of application of the two criteria we show that the efficiency first relation may have a cycle whereas the equity first relation is transitive we also characterize and compare the sets of maximal elements for these social preference relations in the edgeworth box and examine the nonemptiness of the sets journal of economic literature classification numbers d71 d63 d61

egalitarian equivalent cost sharing of a public good in an economy with one public and one private good egalitarian equivalent cost sharing consists of finding the highest public good level x such that consuming x for free yields a feasible utility distribution the corresponding feasible allocation typically unique called egalitarian equivalent is in the core of the economy conversely any cost sharing method satisfying pareto optimality cost monotonicity nobody suffers a utility loss if the production technology improves upon ceteris paribus and individual rationality no single agent coalition objects or no private transfers no agent receives a positive amount of private good must select an egalitarian equivalent allocation in every economy copyright 1987 by the econometric society

reasons for the development of islands of innovation evidence from hertfordshire this paper analyses why innovations often cluster in a few metropolitan islands of innovation the reason for this interest is that a growing body of neo schumpeterian economic theory argues that economic recovery after periods of economic recession and depression such as we have seen during the 1980s and early 1990s is driven by innovations these do not spring up all over the country but are spatially concentrated in a small number of metropolitan regions it is therefore important to know why this is so in order to evaluate the effectiveness of various uk and eu public policies whose specific objectives are to stimulate local and regional economic development agglomeration theory is used in order to understand the driving forces behind the spatial clustering of new innovations this leads to four explanatory hypotheses these are that innovation is facilitated by agglomeration in order to reduce distance transaction costs between firms in different spaces or by local factor conditions which provide

no envy and consistency in economies with indivisible goods we consider the problem of fair allocation in economies with indivisible goods our main objective is to identify appealing subsolutions of the no envy solution we formulate desirable properties of solutions and look for solutions satisfying them given an allocation chosen by a solution for some economy and given a subgroup of the agents consider the problem of fairly distributing among its members the resources that this group has collectively received the solution is consistent if it recommends that the same bundle be attributed to each of these agents as initially we show that there is no proper subsolution of the no envy solution that satisfies consistency however many subsolutions satisfy bilateral consistency or the converse of consistency but again there is no proper subsolution satisfying these two properties together

sympathy for the diligent and the demand for workfare abstract we study the role of fairness concerns in the demand for redistribution through workfare in the first part of the paper we present new evidence from a survey we show that individuals are more generous towards poor people whom they perceive to be diligent workers relative to poor people whom they perceive to be non diligent a social preference that we label sympathy for the diligent this preference is much stronger than preferences regarding other characteristics of the poor such as race nationality and disability more important we show that subjects with higher sympathy for the diligent have a stronger preference for workfare programs in the second part of the paper we incorporate our empirical findings into a model of income redistribution we consider the case of a benevolent government with fairness concerns that prioritizes the well being of individuals who exert the most effort we characterize the optimal conditions under which the government introduces work requirements even if wasteful work requirements can be optimal because they allow for a better distinction between individuals who exert great effort and individuals who do not however if the government lacks commitment power the availability of screening through work requirements leads to a lower equilibrium effort and possibly a pareto dominated allocation

the design of income maintenance programmes this paper provides a comprehensive treatment of a basic income maintenance problem for a group of individuals who differ in their income generating abilities it stresses the impact that imperfect information about such abilities has on programme design the analysis serves two purposes first we are able to unify the theoretical literature on the income maintenance problem second we examine the impact of allowing the government to impose workfare on recipients of income support in addition to being of policy interest this is a theoretically challenging problem since it requires solving a multi dimensional screening problem the solution that we find is strikingly simple it separates the poor into two categories with the lower income groups subject to workfare while facing a 100 marginal tax rate on earnings the second group does no public work and is offered a benefit schedule which taxes earnings at a lower rate

optimal participation taxes addressing extensive labour supply responses the literature has established a case for larger transfers to the working poor than to even poorer non working people this paper casts new light on this result i argue that the result hinges crucially on the labour supply responses of people in income brackets above that of the working poor then distinguishing between more and less poor working people i show that if a single working type faces a negative tax it is the poorer one who does finally i endogenize wages and show that key conditions will be of the same form as before

exploring environmental perspectives in lowland agriculture a q methodology study in east anglia uk abstract the role of agriculture in rural areas is changing significantly in europe with environmental protection and enhancement and provision of amenity and recreation increasingly emphasized both in public debate and in new policy initiatives faced by these shifting priorities it is increasing important to understand how farmers themselves perceive their roles in relation to environmental management in particular as recent research in new institutional economics has shown frey b s 1997 not just for the money edward elgar cheltenham policy assumptions and instruments that are at odds with the underlying motivations of agents may actually reduce achievement of policy objectives if they act to degrade beneficial norms or alter the basis on which agents make choices understanding how farmers conceive of their environmental rights and responsibilities is therefore important in helping to design agri environmental measures that can complement rather than conflict with the underlying normative assumptions that farmers themselves hold this study employs q methodology to investigate the perceptual frameworks of a sample of uk arable and mixed lowland farmers regarding the appropriate way in which to approach the environmental management of agricultural land the q analysis identifies five distinct perspectives on notions of agricultural stewardship we term these environmentalists progressives commodity conservationists jeffersonians and yeomen we discuss the main characteristics of these groups and comment on these results in the context of current uk agri environmental policy which is changing both the presumptions of farmers entitlements to agricultural payments and the expectations pertaining to farmers in relation to environmental responsibilities in conclusion we suggest that q methodology can be a valuable way of demonstrating the nature of the mental frameworks of actors in a particular context and this enables us to formulate some important questions regarding the motivations of land managers in the context of a rapidly changing rural policy

spatial proximity and firm survival in a declining industrial district the case of knitwear firms in baden wu rttemberg the literature on small firm networks in industrial districts postulates the importance of territorial proximity for business innovation and regional development but empirical research to test this proposition is sparse while there is some research on the extent of interfirm co operation little is known about the performance outcomes of co operation i develop competing hypotheses from institutional ecological and random action theories concerning the survival chances of firms located in geographic proximity and test them with data on the complete population of knitwear firms in baden wurttemberg germany for the period from 1960 to 1998 proportional hazard estimates show that location in clusters of firms in the same industry increased business failure rates and location in diversified clusters of firms operating in complementary industries reduced failure rates the empirical results are most consistent with the ecological model of localized competition in resource environments la documentation

redistributive taxation with heterogeneous relative consumption concerns this paper studies the impact of redistributive income taxation in a society where only some individuals are motivated by relative consumption concerns introducing this heterogeneity raises theoretical challenges since i earned income becomes an imperfect indicator of underlying ability and ii relative concerns may be inadmissable in the social objective a new behavioural model is developed in which only relatively concerned individuals choose work effort strategically linear tax transfer systems schemes are then characterized and simulated for a series of welfarist and non welfarist social objectives and for different degrees of preference heterogeneity a key result is that a government which understands the extent of relative consumption concerns but places no social weight on individuals with such preferences nevertheless sets a significantly more progressive tax system than a government which ignores relative consumption motivations altogether ce memoire examine l impact d une imposition redistributrice sur le revenu dans une societe ou certaines personnes sont motivees par des questions de niveaux de consommation relative cette sorte d heterogeneite souleve certains defis theoriques puisque i les gains sont un indicateur imparfait des habiletes sous jacentes et ii ces malaises quant a la consommation relative peuvent etre inadmissibles au plan de l objectif social on developpe un nouveau modele de comportement dans lequel seulement les personnes preoccupees par leur position relative definissent leur effort de travail strategiquement on definit des systemes d imposition et de transferts lineaires et on les soumet a des simulations pour une serie d objectifs sociaux a saveur welfariste et non welfariste et pour differents degres d heterogeneite de preferences un resultat crucial est qu un gouvernement qui comprend l importance des sensibilites aux resultats relatifs mais qui ne donne aucune valence sociale aux personnes qui ont de telles preferences neanmoins met en place une fiscalite plus progressive de maniere significative qu un gouvernement qui ignore completement ces motivations fondees sur la consommation relative

nash equilibrium and welfare optimality if is a set of social alternatives a social choice rule scr assigns a subset of a to each potential profile of individuals preferences over a where the subset is interpreted as the set of welfare optima a game form or mechanism implements the social choice rule if for any potential profile of preferences 1 any welfare optimum can arise as a nash equilibrium of the game form implying in particular that a nash equilibrium exists and 2 all nash equilibria are welfare optimal the main result of this paper establishes that any scr that satisfies two properties monotonicity and no veto power can be implemented by a game form if there are three or more individuals the proof is constructive

international comparisons of living standards by equivalent incomes we propose a measure of living standards for international comparisons based on gdp per capita the measure incorporates corrections for international flows of income labor risk of unemployment healthy life expectancy household demography and inequalities the method for comparing populations that differ in some non income dimension consists of computing the equivalent variation of income that would make each population indifferent between its current situation and a reference situation with respect to the non income dimension this is applied to 24 oecd countries the obtained ranking of countries differs substantially from the gdp ranking

fair allocation of indivisible goods and criteria of justice a set of n objects and an amount m of money is to be distributed among m people example the objects are tasks and the money is compensation from a fixed budget an elementary argument via constrained optimization shows that for m sufficiently large the set of efficient envy free allocations is nonempty and has a nice structure in particular various criteria of justice lead to unique best fair allocations that are well behaved with respect to changes of m this is in sharp contrast to the usual fair division theory with divisible goods

a review article the case against the use of the sum of compensating variations in cost benefit analysis this paper presents a case against the use of the sum of compensating varia tions as a cost benefit test we argue that 1 the ethical judginents implied by the test are not defensible 2 positive sums of compensating variations occur without potential pareto improvements resulting in social preference reversals without simultaneous scitovsky re versals 3 when lump sum transfers are feasible a positive sum of compensating variations is necessary but not sufficient for a potential pareto improvement 4 in order to eliminate preference reversals and intransitivities all households must have almost identical quasi homothetic preferences a condition that is not satisfied in real economies
