addressing leakage in the eu ets border adjustment or output based allocation the eu ets has been criticised for threatening the competitiveness of european industry and generating carbon leakage i e increasing foreign greenhouse gas emissions two main options have been put forward to tackle these concerns border adjustments and output based allocation i e allocation of free allowances in proportion to current production we compare various configurations of these two options as well as a scenario with full auctioning and no border adjustment against this background we develop a model of the main sectors covered by the eu ets electricity steel cement and aluminium we conclude that the most efficient way to tackle leakage is auctioning with border adjustment which generally induces a negative leakage a spillover this holds even if the border adjustment does not include indirect emissions if it is based on eu rather than foreign specific emissions or for some values of the parameters if it covers only imports another relatively efficient policy is to combine auctioning in the electricity sector and output based allocation in exposed industries especially if free allowances are given both for direct and indirect emissions i e those generated by the generation of the electricity consumed although output based allocation is generally less effective than border adjustment to tackle leakage it is more effective to mitigate production losses in the sectors affected by the ets which may ease climate policy adoption c 2011 elsevier b v all rights reserved

resource allocation affluence and deadweight loss when relative consumption matters abstract we explore the link between affluence and well being using a simple general equilibrium model with a pure veblen good individuals derive utility from the pure veblen good based solely on how much they consume relative to others in equilibrium consumption of the pure veblen good is the same for everyone so the veblen good contributes nothing to utility hence resources devoted to the veblen good provide us with a measure of deadweight loss we ask under what preference conditions does the proportion of productive capacity devoted to the pure veblen good increase as an economy becomes more affluent in a relatively general preference framework we derive a sufficient condition for which the veblen good crowds out standard forms of consumption and leisure resulting in an inverse relationship between affluence and utility with additional structure on the model we are able to fully characterize the behavior of deadweight loss and utility as an economy becomes more affluent

do relative income and income inequality affect consumptionq evidence from the villages of rural china abstract this article examines how a household s consumption rate is affected by its relative income and income inequality within a community based on the theory of social status seeking in consumption we test hypotheses related to these factors using a unique panel data set of rural households in china observed within a few hundred villages between 2003 and 2006 we find that the household s consumption rate is negatively related to the relative income position after controlling for the absolute income and positively related to the income inequality of the village we confirm these with different measurements of relative position

carbon pass through in the electricity sector an econometric analysis abstract we conduct an econometric analysis to investigate the carbon pass through in the greek electricity sector for this reason we utilize a rich micro level panel dataset including hourly data for 24 thermal power plants spanning the period from january 2014 to december 2017 in order to study the pass through of emissions costs to wholesale electricity prices we employ an instrumental variable approach our findings survived several robustness checks accounting for logged linear and non linear econometric specifications the empirical results indicate the existence of an almost complete pass through revealing that retailers fully internalize the cost of co2 permits this study incurs important policy implications since the complete pass through signify that wholesale electricity prices will increase at least in the short run however the overall effect on retail prices will be mostly affected by the amount of co2 permits and the fuel energy mix

getting ahead of the joneses when equality increases conspicuous consumption among bottom tier consumers it is widely believed that increasing the equality of material possessions or income in a social group should lead people at the bottom of the distribution to consume less and save more however this prediction and its causal mechanism have never been studied experimentally five studies show that greater equality increases the satisfaction of those in the lowest tier of the distribution because it reduces the possession gap between what they have and what others have however greater equality also increases the position gains derived from status enhancing consumption since it allows low tier consumers to get ahead of the higher proportion of consumers clustered in the middle tiers as a result greater equality reduces consumption when consumers focus on the narrower possession gap but it increases consumption when they focus on the greater position gains i e when consumption is conspicuous social competition goals are primed and the environment is competitive

will the consumption externalities effects in the ramsey model please stand up abstract according to the prior literature in a ramsey model consumption externalities have no impact on steady state behavior once labor supply is exogenous in contrast this paper argues that in the presence of technical change consumption externalities always affect steady state behavior via their impact on the elasticity of marginal utility of consumption

long run welfare under externalities in consumption leisure and production a case for happy degrowth vs unhappy growth in this paper we contribute to the debate on the relationship between growth and well being by examining an endogenous growth model where we allow for externalities in consumption leisure and production we analyze three regimes a decentralized economy where each household makes isolated choices without considering their external effects a planned economy where a myopic planner fails to recognize both leisure and consumption externalities but recognizes production externalities and a planned economy with a fully informed planner we first compare the balanced growth paths under the three regimes and then we numerically investigate the transition to the optimal balanced growth path we provide a number of findings first in a decentralized economy growth or labor or both are greater than in the regime with a fully informed planner and hence are sub optimal from a welfare standpoint second a myopic intervention which overlooks consumption and leisure externalities leads to more growth and labor than in both the decentralized and the fully informed regime third we provide a case for happy degrowth a transition to the optimal balanced growth path that is associated with downscaling of production a reduction in private consumption and an ongoing increase in leisure and well being

consumption externalities and monetary policy with limited asset market participation this article explores the interaction between consumption externalities and limited asset market participation lamp in the standard new keynesian model we assess the performance of simple taylor type interest rate rules with respect to a equilibrium determinacy b the model s ability to simultaneously generate output and inflation volatility similar to the pre volcker era and c the model s response to a technology shock we find that when individual preferences are affected by average household consumption aggregate consumption externality stronger externalities increase the range of lamp for which multiple equilibria arise even if the policy rule satisfies the taylor principle the interaction of lamp and externalities can generate vast inflation output relative volatility in line with the one observed in the data in the 1970s according to our analysis consumption externalities also affect the responses of endogenous variables to total factor productivity shocks jel e4 e5

technological innovation and real investment booms and busts abstract we investigate why new high risk technologies can attract excessive and often unprofitable investment we develop an equilibrium model in which rational risk averse agents overinvest in a risky technology possibly to the point that its expected return is negative overinvestment results from relative wealth concerns which arise endogenously from the imperfect tradability of future endowments competition over future consumption leads to an indirect utility for wealth with keeping up with the joneses properties that can induce herding because overinvestment increases with the risk of the technology our model can explain why new risky technological innovations may promote investment bubbles

trickle down consumption financial deregulation inequality and indebtedness over the last thirty years the u s experienced a surge in income inequality coupled with increasing levels of borrowing we model an olg economy populated by two types of household that care about how their consumption compares to that of their peers in this framework individual debt to income ratios decrease with income increases in consumption of rich households lead to increases in consumption of the rest and aggregate borrowing increases with income inequality we calibrate our model to evaluate the welfare implications of the process of nancial liberalization that began in the 1980s our analysis suggests that some of the nancial developments that lead to the recent expansion of credit may have decreased rather than increased welfare

tax policy and aggregate demand management under catching up with the joneses this paper examines the role for tax policies in productivity shock driven economies with catching up with the joneses utility functions the optimal tax policy is shown to affect the economy countercyclically via procyclical taxes i e cooling down the economy with higher taxes when it is overheating in booms and stimulating the economy with lower taxes in recessions to keep consumption up thus models with catching up with the joneses utility functions call for traditional keynesian demand management policies but for rather unorthodox reasons

welfare implications of the interaction between habits and consumption externalities we analyze the welfare properties of the equilibrium path of a growth model where both habits and consumption externalities affect the utility of consumers our analysis highlights the crucial role played by complementarities between externalities and habits in order to generate an infficient dynamic equilibrium in particular we show that the competitive equilibrium is inefficient when consumption externalities and habit adjusted consumption are not perfect substitutes

a two sector model of endogenous growth with leisure externalities abstract this paper considers the impact of leisure preference and leisure externalities on growth and labor supply in a lucas 1988 12 type model as in gomez 2008 7 with a separable non homothetic utility and the assumption that physical and human capital are both necessary inputs in both the goods and the education sectors in spite of the non concavities due to the leisure externality the balanced growth path is always unique which guarantees global stability for comparative static exercises we find that small differences in preferences toward leisure or in leisure externalities can generate substantial differences in hours worked and growth which may play a significant role in explaining differences in growth paths between the us and europe in addition to the mechanisms uncovered in prescott 2004 15 relying on differing marginal tax rates on labor income our model indicates however that a higher preference for leisure or leisure externality implies less growth but also less education attainment which seems counterfactual

saving rates and poverty the role of conspicuous consumption and human capital poor families around the world spend a large fraction of their income consuming goods that do not appear to alleviate poverty while saving at low rates we suggest that individuals care about economic status and interpret this behaviour as conspicuous consumption intended to provide a signal about unobserved income we show that if human capital is observable and correlated with income then a signalling equilibrium in which poor individuals tend to spend a large fraction of their income on conspicuous consumption can emerge this equilibrium gives rise to an increasing marginal propensity to save that might generate a poverty trap

relative wealth concerns and financial bubbles we present a rational general equilibrium model that highlights the fact that relative wealth concerns can play a role in explaining financial bubbles we consider a finite horizon overlapping generations model in which agents care only about their consumption though the horizon is finite competition over future investment opportunities makes agents utilities dependent on the wealth of their cohort and induces relative wealth concerns agents herd into risky securities and drive down their expected return even though the bubble is likely to burst and lead to a substantial loss agents relative wealth concerns make them afraid to trade against the crowd

a structural econometric model of joint consumption of goods and recreational time an application to pick your own fruit this article develops a structural econometric consumer demand model for goods which have time and monetary costs and where time spent obtaining the goods also enters into the utility function the model is used to analyze customers decision to buy pick your own versus preharvested strawberries at north carolina pick your own fruit operations the analysis distinguishes the effect of time as a resource constraint and time that provides utility demand for strawberries sold at the operations is price elastic and demand for pick your own strawberries is less price elastic than demand for preharvested strawberries copyright 2008 oxford university press

keeping up with the ageing joneses in this paper we consider the implications of relative consumption externalities in the blanchard yaari overlapping generations framework unlike most of the macroeconomic literature that studies this question the differences between agents and thus in their relative position persist in equilibrium we show in our fixed employment model that consumption externalities lower consumption and the capital stock in long run equilibrium a result in sharp contrast to the recent findings of liu and turnovsky 2005 in addition we solve for the intertemporal path of the economy to investigate its response to demographic shocks specifically to permanent changes in the birth and death rates

status effects public goods provision and excess burden abstract most studies of the optimal provision of public goods or the excess burden from taxation assume that individual utility is independent of other individuals consumption this paper investigates public good provision and excess burden in a model that allows for interdependence in consumption in the form of status relative consumption effects in the presence of such effects consumption and labor taxes no longer are pure distortionary taxes but have a corrective tax element that addresses an externality from consumption as a result the marginal excess burden of consumption taxes is lower than in the absence of status effects and will be negative if the consumption tax rate is below the pigouvian rate correspondingly when consumption or labor tax rates are below the pigouvian rate the second best level of public goods provision is above the first best level contrary to findings from models without status effects for plausible functional forms and parameters relating to status effects the marginal excess burden from existing u s labor taxes is substantially lower than in most prior studies and is negative in some cases

optimal dynamic taxation with distinctive forms of social status attainment we examine the role of both consumption and wealth induced social comparisons in setting dynamic optimal income taxation under complete information state invariant labor income taxes are used to remedy the externality caused by consumption induced social comparisons while state contingent capital income taxes are used to remedy the externalities caused by both consumption and wealth induced ones under incomplete information distinct types of agents are subject to an identical marginal capital income tax which removes social comparisons to solve the information problem low productivity agents could be subject to a lower marginal labor tax than high productivity agents which contradicts the traditional result in the mirrlees stiglitz models this article is protected by copyright all rights reserved

political economy of growth with a taste for status abstract this paper investigates the political economy of growth when individuals prefer high levels of relative consumption a pivotal voter determines the equilibrium tax on capital the revenues from which fund the provision of productive public goods the taste for status and the distributions of wealth and political power interact to generate stylized versions of oligarchies middle class democracies and populist democracies a rise in the taste for status increases the role of distributional concerns in policy preferences lowering growth in an oligarchy or populist democracy but increasing it in a middle class democracy in addition the egalitarian redistribution of wealth or political power causes growth to first rise and then fall as the equilibrium tax rate approaches and then exceeds its growth maximizing level generating inverse u shaped relationships between democracy and growth and inequality and growth

consumption and happiness we examine the relationship between relative consumption and happiness using panel data for china an important developing country we find that consumption has a positive effect on happiness an

can consumption spillovers be a source of equilibrium indeterminacy in the framework of a one sector exogenous growth model we show that consumption externalities are not a source of equilibrium indeterminacy when the labor supply is inelastic whereas they are under endogenous labor supply in particular when the marginal rate of substitution between own consumption and the others consumption is constant along the equilibrium path the equilibrium may exhibit indeterminacy when the following two conditions are simultaneously satisfied i both consumption and production externalities are present and ii the elasticity of the labor demand is larger than the elasticity of the frisch labor supply in contrast when the marginal rate of substitution is not constant the equilibrium may exhibit indeterminacy even if the previous two conditions are not met in this case the equilibrium can exhibit indeterminacy even if production externalities are absent we also show that these results do not apply to an endogenous growth model where indeterminacy may arise only when condition ii is met

demand elasticities from a discrete choice model the natural christmas tree market a procedure is demonstrated for estimating market level demand elasticities from household data suffering from sample selectivity problems the procedure uses mcfadden s nested multinomial logit model and is applied to the natural christmas tree market results indicate that the own price elasticity of natural christmas trees is 0 674 and the cross price elasticity of natural christmas trees with respect to artificial christmas trees is 0 188 these are the first known demand elasticity estimates for the natural christmas tree market

income redistribution consumer credit and keeping up with the riches in this study we set up a dynamic stochastic general equilibrium dsge model with upward looking consumption comparison and show that consumption externalities are an important driver of consumer credit dynamics our model economy is populated by two different household types investors who hold the economy s capital stock own the firms and supply credit and workers who supply labor and demand credit to finance consumption furthermore workers condition their consumption choice on the investors level of consumption we estimate the model and find a significant keeping up mechanism by matching business cycle statistics in reproducing credit moments our proposed model significantly outperforms a model version in which we abstract from consumption externalities

optimal emissions tax rates under habit formation and social comparisons abstract the existing climate models ignore the behavioral anomalies of households and conclude that the optimal environmental tax rate should comove with business cycles however this assumption has received extensive criticism recently to this end this paper studies the optimal emissions tax rate when households are bounded rational in particular we calculate the optimal climate policy in a dynamic stochastic general equilibrium dsge model that features households with habit formation internal habits and social comparisons external habits compared to the benchmark model without consumption externality the social comparisons model amplifies consumption volatility but produces a similar response of pollutant emissions in the presence of the three types of economic shocks considered in contrast the habit formation model decreases the volatility of both consumption and pollutant emissions in contrast to the previous result that the optimal emissions tax rate should be procyclical we find that the social comparisons model largely mitigates the procyclicality of optimal emissions tax rates and the optimal emissions tax rates under the habit formation model remain constant in response to all the economic shocks considered

marginal co2 cost pass through under imperfect competition in power markets abstract in line with economic theory carbon ets determines a rise in marginal cost equal to the carbon opportunity cost regardless of whether carbon allowances are allocated free of charge or not this paper aims at evaluating to what extent firms in imperfectly competitive markets will pass through into electricity prices the increase in cost by using the load duration curve approach and the dominant firm with competitive fringe model we show that the result is ambiguous the increase in price can be either lower or higher than the marginal co2 cost depending on several structural factors the degree of market concentration the available capacity whether there is excess capacity or not the power plant mix in the market and the power demand level peak vs off peak hours the empirical analysis of the italian context an emblematic case of imperfectly competitive market which can be split into four sub markets with different structural features provides a contribution supporting the model predictions market power therefore would determine a significant deviation from the full pass through rule but we cannot know the sign of this deviation a priori i e without before taking carefully into account the structural features of the power market

jealousy and underconsumption in a one sector model with wealth preference abstract the present paper examines the effects of consumption externalities on economic performance in a one sector model with wealth preference the presence of the wealth preference generates a wealth effect in consumption growth which plays a crucial role for consumption externalities to have impacts on the economy our main findings are i regardless of the assumption of inelastic labor supply the distortionary effect of consumption externalities stays in the long run ii the income tax as well as the consumption tax can modify the efficiency and iii the numerical simulations supplement theoretical findings

does ecological economics have a future contradiction and reinvention in the age of climate change abstract this paper addresses the role of neoclassical methodologies in ecological economics and the contradictions these methodologies pose to the field s critical founding principles we first consider robert costanza s treatment of nicholas stern s global deal and then survey climate change related articles published in this journal over the past five years this survey reveals how mainstream neoclassical methodologies dominate discourse and do so by marginalizing more critical political economy analyses this situation imperils the field s founding vision of a no growth steady state it also fails to address the related growth dynamics of capitalism without such a critical treatment the field s formal embrace of methodological pluralism actually entails an ideological empiricism that renders ecological economics theoretically incoherent this situation undermines the field s historical promise as an alternative economic paradigm ecological economics now faces a problematic future its survival in a form faithful to its founding vision will require an explicit choice to address its internal contradictions and reinvent itself in ways relevant to our contemporary context without such a choice ecological economics will likely succumb to an implicit acceptance of the hegemony of mainstream economic methodologies and their pro growth imperatives

security design with status concerns abstract this paper provides a status based explanation for convertible securities an entrepreneur with status concerns inducing risk taking decides how to finance the firm and how to dynamically manage it solving analytically for the optimal security we find that it is substantially similar to a convertible security our model can explain why convertible securities are mainly issued by start ups and small firms as we show that their salient characteristics higher volatility and dynamic flexibility accentuate incentives to issue convertible securities we also provide analytical results relevant to quantifying how status concerns affect credit risk an established factor behind security choice

social comparisons and optimal taxation in a small open economy in this paper we analyze how international capital mobility affects the optimal labor and capital income tax policy in a small open economy when consumers care about relative consumption the main

admiration is a source of indeterminacy abstract are consumption externalities sources of indeterminacy the answer is negative in conventional wisdom this paper shows consumption externalities establish local indeterminacy if the degree of decreasing impatience is sufficiently large dynamic models with indeterminacy are valuable as they tend to explain economic fluctuations without relying on exogenous shocks and question interpretation of simple estimation obtained by pooling data among others

monetary policy stock prices and consumption externalities abstract we study interest rate rules responding to stock prices in a sticky price sticky wage new keynesian framework subject to consumption externalities for given wage rigidity such rules are beneficial to equilibrium determinacy if households preferences feature sufficiently strong keeping up with the joneses externalities

relative status and satisfaction abstract this paper studies the effect of income rank on satisfaction we hypothesize that a person s satisfaction depends on a comparison of own rank and rank of one s parents estimates using data from the german socio economic panel support the relative rank hypothesis

social comparisons in oligopsony abstract a large body of evidence suggests that social comparisons matter for workers valuation of the wage they receive the consequences of social comparisons in imperfectly competitive labor markets are less well understood we analyze an oligopsonistic model of the labor market where workers derive dis utility from comparing their own wage with wages paid at other firms as social comparisons become more prevalent all workers are paid higher wages the wage distribution becomes more equal and employment shifts to high productivity firms moreover the total wage bill and output increase while aggregate profits decline overall welfare rises our theoretical results have implications for estimating the elasticity of the labor supply curve facing a firm

optimal taxation when consumers have endogenous benchmark levels of consumption i examine optimal taxes in an overlapping generations economy in which each consumer s utility depends on consumption relative to a weighted average of consumption by others the benchmark level of consumption as well as on the level of the consumer s own consumption the socially optimal balanced growth path is characterized by the modi ed golden rule and by a condition on the intergenerational allocation of consumption in each period a competitive economy can be induced to attain the social optimum by a lump sum pay as you go social security system and a tax on capital income

relative consumption benchmarks abstract i construct a general multi good model of consumption externalities that allows for relative jealousies and relative keeping up with the joneses effects these relative social consumption contexts have the ability to reinforce or mitigate each other

conspicuous consumption and race evidence from south africa abstract a century ago thorstein veblen introduced socially contingent consumption into the economic literature this paper complements the scarce empirical literature by testing his conjecture on south african household data and finds that black and coloured households spend relatively more on visible consumption than comparable white households following the approach of charles et al 2009 this paper explores whether the differences in visible expenditures can be explained with a signaling model of status seeking moreover it is assessed to which extent positional concerns motivate conspicuous consumption although the socially contingent share in visible consumption increases with income different incentives to consume conspicuously seem to explain that at every level of income black households spend relatively more on visible consumption than comparable white households in contrast to the findings of charles et al 2009 where differential spending on conspicuous consumption can be found also within each group separately the model s core hypothesis fails to hold within the group of white south africans

conspicuous consumption and race using nationally representative data on consumption we show that blacks and hispanics devote larger shares of their expenditure bundles to visible goods clothing jewelry and cars than do comparable whites these differences exist among virtually all subpopulations are relatively constant over time and are economically large although racial differences in utility preference parameters might account for a portion of these consumption differences we emphasize instead a model of status seeking in which conspicuous consumption is used as a costly indicator of a household s economic position using merged data on race and state level income we demonstrate that a key prediction of the status signaling model that visible consumption should be declining in reference group income is strongly borne out in the data for each racial group moreover we show that accounting for differences in reference group income characteristics explains most of the racial difference in visible consumption

conformism and structural change using a simple multisector model of endogenous growth we show that commodity specific consumption externalities can be a source of structural change when the degrees of consumption externalities are different between goods each sector grows at a different rate however the aggregate economy exhibits balanced growth in that capital stock and expenditure grow at the same constant rate a three sector version of our model may reconcile kaldor s stylized facts with empirically plausible profiles of industrial structure transformation

international status seeking trade and growth leadership we study a two country endogenous growth model where the utility of agents in developing countries is affected by consumption gaps with advanced economies international status seeking tends to revert growth differentials in favour of the developing country preferences with endogenous status desire generate convergence in growth rates in the presence of structural gaps and convergence in income levels if productivity differences disappear this process is driven by declining terms of trade and faster capital accumulation of the status seeker the model predictions are shown to be consistent with the stylized facts that characterized the growth performance of east asian economies

the tragedy of the commons in a fishery when relative performance matters this paper presents a simple model of a common access fishery where fishermen care about relative performance as well as absolute profits our model captures the idea that status which depends on relative performance in a community influences a person s well being in our main specification relative performance depends on the absolute difference in after tax profits we show that overharvesting resulting from the tragedy of the commons problem is exacerbated by the desire for higher relative performance leading to a smaller steady state fish stock and smaller steady state profit for all the fishermen we also consider alternative specifications where status depends on the absolute difference in harvests or relative difference in profits or where there is heterogeneity in the degree to which status matters or allowing for the possibility of extinction in all these specifications status further reduces the steady state fish stock we examine taxes and an individual quota as policy alternatives and find support for using the direct quantity method to implement the socially efficient stock level

occupational mobility and the distribution of occupational success among young men interpretation of the distribution of occupational success depends crucially on an understanding of the process of mobility if the holders of low paying jobs this year are just as likely as anyone else to hold good jobs next year then the lower tail of the earnings distribution is not a matter of great social concern further if the distribution of success is primarily determined by a random process the prospects for a significant reduction in the inequality of earnings are unfavorable on the other hand high mobility in the short run may conceal systematic stratification of the labor force it may be that the same individuals spend most of their time in the worst jobs if so luck and random events may play a small role in the distribution of well being inequality may be a major issue and the elimination of stratification may hold out the promise of an important reduction in inequality simple tabulation of distributions of success and of mobility among categories of success cannot answer the basic question of the role of stratification in this paper we develop a model and statistical method for studying mobility and relating it to characteristics upon which stratification may be based our study rests on annual interviews conducted from 1966 through 1969 with about 3 000 white males born between 1942 and 1952 1 we find that mobility is closely related to personal characteristics especially intelligence and education men with high iqs and extensive education are more likely to move to high paying jobs and are more likely to remain in them nevertheless random events dominate the distribution of occupational success in the short run our results strongly support the finding of christopher jencks and his collaborators that redistribution of the determinants of earnings would do almost nothing to reduce the observed inequality of annual earnings

does emission permit allocation affect co2 cost pass through a theoretical analysis abstract carbon emissions trading may result in co 2 cost pass through and its rate is influenced by a number of factors this paper theoretically investigates how emission permit allocation affects co 2 cost pass through rate by developing a nash cournot oligopolistic market equilibrium model we find that the derived co 2 cost pass through rates are consistent when grandfathering and auctioning rules are used for permit allocation which are higher than that for benchmarking rule it has also been found that the magnitude of co 2 cost pass through rate is relevant to the type of definition product market structure and average carbon intensity of the industry we suggest that policy makers first use benchmarking rule to attract firms to participate at the early stage of emissions trading system ets and then take auctioning rule when ets is well developed

relative income effects on subjective well being in the cross section abstract recent work suggests that a person s subjective well being swb depends to a large degree on relative income focusing on the underlying identification this paper makes four contributions to this literature it describes the aggregation problem with past studies implements an estimation strategy to overcome this problem finds micro level evidence in support of the hypothesis that relative income does matter in individual assessments of swb and uses cross section estimates to replicate the aggregate time series the evidence further indicates that relative income effects may be smaller at low income levels the results are obtained from ordered probit techniques and the general social survey gss

a variety expansion model of growth with external habit formation abstract this paper introduces consumption externalities into one of the base line models of growth in which continuing expansion of product variety sustains long term growth we assume that consumers set a benchmark stock of consumption for each good so that there are commodity specific external effects each good is produced by a monopolistically competitive firm and the firm exploits the presence of consumption external effects in determining its profit maximizing price given those settings we show that the introduction of consumption externalities may affect the balanced growth characterization transitional dynamics and policy effects in fundamental manners

asymmetric and non atmospheric consumption externalities and efficient consumption taxation abstract we analyze the effects of a generalized class of negative consumption externalities asymmetric and non atmospheric on the structure of efficient commodity tax programs households are not only concerned about consumption reference levels that is they gain utility from keeping up with the joneses but they also exhibit altruism two sets of efficient tax regimes are compared based on a welfarist and a non welfarist optimality criterion respectively altruism turns out not to be at odds with the consumption externalities rather altruism implicates a bound on efficient utility allocations a non welfarist government tolerates less inequality than a welfarist one in the welfarist non welfarist case first best personalized commodity tax rates respond highly sensitively barely to whether or not a consumption externality is asymmetric or non atmospheric if personalized commodity tax rates are not available second best case the tax rate on a non positional good is typically different from zero for corrective reasons for plausible functional forms and parameter values numerical simulations suggest that second best tax rates are rather insensitive with respect to both the optimality criterion and the nature of the consumption externality

is more always better a survey on positional concerns abstract we use survey data to provide some empirical information about concerns regarding relative standing respondents chose between a world where they have more of a good than others and one where everyone s endowment of the good is higher but the respondent has less than others questions asked about education attractiveness and intelligence for one s child and oneself income vacation time approval and disapproval from a supervisor and papers to write half of the respondents preferred to have 50 less real income but high relative income concerns about position were strongest for attractiveness and supervisor s praise and weakest for vacation time

nosy preferences benevolence and efficiency author affiliation chetan dave cdave nyu edustefan dodds sdodds uwinnipeg ca acknowledgment we would like to thank ingela alger sheryl ball nathan berg tarek coury rachel croson frances woolley participants at the 2008 canadian economics association meetings seminar participants at queen s university and two anonymous referees for valuable comments all errors are those of the authors 1 introductionthe pareto principle declares that if everyone in a society prefers some social state of the world x to another state y then the aggregated social ranking should reflect this as well minimal liberalism requires that no individual s preference relation between social states say z and w be violated in the social choice provided that the position of other individuals is unaffected across states z and w both of these principles can be appealing to economists as they evaluate the normative features of various policies however the liberal paradox of sen 1970 demonstrates that the pareto principle and minimal liberalism are potentially at odds with one another the paradox shows that if individuals possess nosy preferences that is they hold opinions about what others should do even though their own material well being is unaffected by others actions then it is in general impossible to arrive at a unique social choice that jointly satisfies these two axioms 1 as an elegant proof by contradiction the paradox adds to the list of social choice impossibilities 2sen s paradox highlights the tension between freedom of choice and efficiency with nosiness as the key ingredient in this article we re examine this tension by using recent insights from behavioral economics the idea that individuals may have concern for others namely altruism is well established in the behavioral economics literature becker 1974 however the concept of nosy preferences and what they imply for collective choice environments has not been extensively studied from a behavioral perspective here we provide such a study to do so we recast nosiness as a new form of social preference in a strategic setting this insight stems from the analysis of segal and sobel 2007 who consider a model where players in a game possess preferences over both outcomes and strategies employed by all players we embed our version of nosiness into a more general model of social preferences individuals in the model derive utility from three sources intrinsic payoffs from the outcomes of strategic choice nosy payoffs based on specific actions taken by other individuals to generate such outcomes and unconditionally altruistic or benevolent payoffs positively related to the extended utilities of other individuals this framework allows us to analyze strategic environments in which there exist interdependent preferences over utilities and actions or just one of these features we apply this particular model of preferences to two environments the first was suggested by aldrich 1977 who sought to provide a game theoretic interpretation of sen s paradox for this environment we are interested in the efficiency of equilibria and to what extent inefficiency depends on particular forms of social preferences we thus offer a new behavioral interpretation of sen s paradox following the behavioral theme we show that when individuals exhibit loss aversion over their own actions the paradox may be robust to schemes that attempt to generate efficiency by restricting action sets ex ante the second environment we consider is that of relative consumption concerns we show that applying our particular model of interdependent preferences to this environment allows us to find cases where individuals will voluntarily restrict consumption to mitigate the negative externality arising from nosy concerns about what others consume

increasing income inequality external habits and self reported happiness a large literature has documented an increase in income equality in the united states over the past several decades see for example david h autor lawrence f katz and melissa s kearney 2006 at the same time real aggregate income has risen markedly and most socioeconomic groups have experienced at least some rise in real purchasing power standard models of consumption which typically assume that an individual s utility is based only on her own consumption would predict that these gains have led to higher levels of happiness for all groups albeit with greater increases for some more than others economists have long recognized however that an individual s utility may depend not only on the level of her own consumption but also on how that level compares with the consumption of others if preferences are characterized by such external habits then the observed widening of the income distribution may have implications for the happiness of different groups that go beyond those associated with the changes in their respective incomes this study combines data from two sources to document the evolution of reported levels of happiness for different socioeconomic groups over the past 25 years and to explore whether those levels have been affected by the changing relative position of these groups within the habit persistence and the macroeconomy

heteroscedasticity of deviations in market bubble moments how the goods and bads lead to the ugly abstractwe conjecture that market bubbles may be the results of the interplay of goods and bads toxic products which develop through three interlocking moments herding swarming and stampeding with deviations marked by heteroscedasticity we use our stylized model of financial predation the consolidated model of financial predation and data we have accumulated through in the field eight year research and the study of 30 years of u s market history in order to explore the foundations of market crises we find that blind trust or the positivity bias and of the fear to miss out on an opportunity to enter exit a market impacts the investors decisions to invest or retract we show how markets are driven towards a make or break predatory dynamic that creates winners and losers due in part to weak regulations and identify a constant k that permeates market behaviours

jealousy and equilibrium overconsumption the idea that the happiness of an individual depends upon the consumption of others is widely viewed as an important feature of our shared social existence recent research in finance has used this idea through consumption externalities to explore asset pricing anomalies consumption externalities potentially break the link between pareto optimality and competitive equilibria and open the door for beneficial government intervention e g lars ljungqvist and harald uhlig 2000 in this paper we delineate two effects that a consumption externality may have an increase in aggregate consumption may a raise the marginal utility of individual consumption relative to leisure and or b lower an individual s utility level we refer to a as keeping up with the joneses henceforth kuj following jordi gali 1994 and we refer to b as jealousy jealousy is a distinct concept from kuj under kuj an individual derives greater utility from additional own consumption relative to leisure when others consume more at the same time higher per capita consumption holding fixed individual consumption can trigger either jealousy so that individual utility falls or admiration so that individual utility rises in section i of this paper we show that jealousy implies that the laissez faire equilibrium consumption level is greater than the optimal level whether preferences exhibit kuj is not necessary for this main result intuitively in the presence of jealousy consumption is similar to pollution overpollution exists because individuals do not take into account the cost of polluting on others not because an increase in economywide pollution makes the return to individual polluting higher similarly overconsumption exists because individuals do not take into account the negative effect of own consumption on jealous others things go in the opposite direction when individuals are admiring in section ii we consider a functional form that encompasses several existing models we show that jealousy determines the optimal tax to correct overconsumption and that kuj is mainly important for asset pricing

we are what we eat obesity income and social comparisons abstract the empirical evidence of a non monotone relation between income and obesity is not well explained we build a theoretical model combining income inequality and social comparisons to explain the link between income and obesity and study tax policy implications for fighting obesity we assume that differences in food consumption patterns between poor and wealthy households partly reflect positionality which is the concern for social status our key assumption is that positionality for low calorie food consumption is positively related to a country s wealth in this framework body weight outcomes reflect competing income and positionality effects yielding the following results we explain the link between average obesity rates and standards of living and suggest the existence of a kuznets curve for obesity in accordance with empirical evidence for cross sections of the population we explain the observed correlation between income and obesity which is positive in poor countries and negative in rich countries we find that increasing the relative cost of high calorie food is less effective at decreasing the relative weight of poor individuals in rich countries than in poor countries

signaling status the impact of relative income on household consumption and financial decisions this paper investigates the importance of status in household consumption and credit decisions using data from the survey of consumer finances linked to tract level data in the american community s

social network structure and status competition in status competition studies the utility of heterogeneous individuals typically depends on an economy wide average indicator of status in our model emulative and jealous agents are embedded in an exogenous network where agent specific reference group is determined by the direct link emanating from the agent similarly to ghiglino and goyal 2010 but in a somewhat different framework we show that individual consumption is proportional to the agent s outbound katz bonacich network centrality measure and equilibrium is generally inefficient more important the negative externality associated with each agent depends on her inbound centrality measure the conspicuousness index a tax based on this index combined with a uniform lump sum transfer attains efficiency

de growth and welfare in an equilibrium model with heterogeneous consumers this paper studies equilibrium growth and voluntary degrowth allowing for heterogeneous and time varying preferences the approach is based on applying a dynamic equilibrium model with externalities in production consumption and leisure preference heterogeneity regarding status competition is modeled by asymmetric consumption externality parameters whereas heterogeneity regarding voluntary simplicity is incorporated by allowing for agent specific restrictions on maximum consumption equilibrium is studied in terms of a balanced growth path bgp numerical examples suggest that degrowth triggered by voluntary simplicity by a subset of consumers less affected by status competition has a positive effect on the aggregate welfare under externalities in consumption and leisure a reduction in status competition increases the aggregate welfare and reduces the equilibrium growth rate simulations suggest that a time varying equilibrium in the heterogeneous preference model with two consumer classes is well approximated by a constant bgp

the relative income hypothesis abstract despite its theoretical dominance the empirical case in favor of the permanent income hypothesis is weak contrary to one of its basic implications a growing body of evidence suggests that rich households save a higher proportion of their permanent income than poor households we propose an overlapping generations economy where households care about relative consumption as a result an individual s consumption is driven by the comparison of his lifetime income and the lifetime income of his reference group a permanent income version of duesenberry s 1949 relative income hypothesis across households the savings rate increases with income while aggregate savings are independent of the income distribution

profit sharing and relative consumption mandatory profit sharing can represent a pareto improvement if labour supply is excessive due to relative consumption effects profit sharing reduces wages if the rise in profit income keeps total income constant there will only be a pareto improving substitution effect

dynamic status effects savings and income inequality this paper advances the hypothesis that the intensity of status preferences depends negatively on the average wealth of society endogenous dynamic status effect in accordance with empirical evidence our theory replicates the contradictory historical facts of an increasing saving rate along with declining returns to capital over time by affecting the dynamics of the saving rate the dynamic status effect raises inequality thereby providing a behavioural mechanism for the observed diverse dynamics of income inequality across countries in countries in which the dynamic status effect is strong weak inequality rises declines over time in response to a positive productivity shock

aspirations health and the cost of inequality how does inequality motivate people and at what cost in a model of perpetual youth people have heterogeneous upward looking aspirations they value their consumption relative to the conditional mean of those above them in the distribution their survival depends on health capital produced from time investment and health goods higher fundamental inequality working through the aspirations gap motivates people to work and save more economic outcomes improve but income and consumption inequality worsen because the poor have less capacity to respond on the labor market by diverting resources from health production aspirations also worsen mortality especially for the poor though relative income has a strong negative effect on personal health inequality has a weak effect on population health explaining an empirical puzzle on the relative income and health gradient

relative consumption and tax evasion abstract relative consumption effects or status concerns that feature jealousy in the sense of dupor and liu 2003 boost consumption expenditure if consumption is financed by labour income such status considerations increase labour supply and hence the tax base a higher taxable income in turn can make tax evasion more attractive we show for various specifications of preferences that the tax base effect generally dominates consequently relative consumption effects tend to reduce tax evasion this is true irrespective of whether tax parameters are exogenous guarantee a balanced budget or are set optimally

time variation in european carbon pass through rates in electricity futures prices the european union emissions trading scheme is a means to price emission allowances electricity market prices should reflect these market prices of emission allowances as they are a cost factor for power producers the pass through rate is the fraction of the emission allowance price that is passed through to electricity market prices it is often measured and presented as an average or a fixed estimate over some time period however we expect that the pass through rates should actually vary over time as electricity supply curves reflect the marginal costs of different producers that differ in emission intensity we apply a kalman filter approach to observe pass through rates in germany and u k and find strong support for time varying instead of fixed pass through rates although policy makers are interested in the impact of a policy on average our results indicate that one needs to be careful with the time frame over which pass through rates are measured for policy evaluation as an incorrect chosen evaluation period could cause an under or overestimation of the pass through rate in addition our model helps to provide policy makers with insight in the development of pass through rates when market circumstances change with respect to power production

rents in the european power sector due to carbon trading abstract the european union emissions trading scheme eu ets has imposed a price on the allowances for co2 emissions of electricity companies integrating this allowance price into the price of electricity earns a rent for companies who have received these allowances for free during phase i 2005 2007 rents corresponding to the aggregate value of allocated allowances amounted to roughly 13 billion per year however due to the specific price setting mechanism in electricity markets true rents were considerably higher this is due to the fact that companies also that have not received any allowances gain additional infra marginal rents to the extent that their variable costs are below the new market price after inclusion of the allowance price producers with low carbon emissions and low marginal costs thus also benefit substantially from carbon pricing this paper develops a methodology to determine the specific interaction of the imposition of such a co2 constraint and the price setting mechanism in the electricity sector under the assumption of marginal cost pricing in a liberalized european electricity market the article thus provides an empirical estimate of the true total rents of power producers during phase i of the eu ets 2005 2007 the eu ets generated in phase i additional rents in excess of 19 billion per year for electricity producers these transfers are distributed very unevenly between different electricity producers in a second step the paper assesses the impact of switching from free allocation to an auctioning of allowances in 2013 we show that such a switch to auctioning will continue to create additional infra marginal rents for certain producers and will leave the electricity sector as a whole better off than before the introduction of the eu ets

impatience and equilibrium indeterminacy abstract this paper extends the neoclassical one sector optimal growth model by postulating that individual agents time preference impatience depends on the economy wide average consumption and average income which are social factors taken as external by individual agents the paper shows that with the socially determined individual time preference local equilibrium indeterminacy can arise moreover local indeterminacy can also be associated with global indeterminacy in many cases the results hold in models with bounded and unbounded growth

empirical specification requirements for two constraint models of recreation choice two constraint models are common in recreation demand analysis because of the important role time can play in consumer choices two versions of roy s identity hold for these models and imply coefficient restrictions on empirical demand functions the two constraint restrictions are fully observable and can be expressed in a form analogous to the slutsky hicks equations in single constraint consumer models empirical specifications that use full prices and full budgets can be consistent with the two constraint models when the marginal value of time is either exogenous or endogenous but models with full prices and money income alone are not copyright 2001 oxford university press

resource grabbing by status conscious agents abstract we introduce a dynamic model of resource grabbing by status conscious agents i e agents value not only their absolute consumption levels but also the relative status within their reference group we explore the effect of the concern for relative consumption on the growth rate and the welfare of an economy where agents appropriate from a common property resource our model shows that the greater is agents concern about their relative status the more aggressively they tend to behave consequently social welfare is lower because the growth rate of the public asset is reduced due to higher extraction rate we also consider the effect of increased heterogeneity and show that social welfare decreases as the distribution of status consciousness among agents widens

consumption externalities production externalities and efficient capital accumulation under time non separable preferences the effects of consumption and production externalities on economic performance under time non separable preferences are examined both theoretically and numerically we show that a consumption externality alone has long run distortionary effects if and only if labor is supplied elastically with fixed labor supply it has only transitional distortionary effects production externalities always generate long run distortions irrespective of labor supply the optimal tax structure to correct for the distortions is characterized we compare the implications of this model with those obtained when the consumption externality is contemporaneous while some of the long run effects are robust there are also important qualitative and quantitative differences particularly along transitional paths

an overview of co2 cost pass through to electricity prices in europe this paper investigates the link between wholesale electricity prices in europe and the co2 cost i e the price of european union allowances euas over the two first phases of the european union emissions trading scheme eu ets we set up a theoretical framework and an empirical model to estimate to what extent daily fluctuations of co2 costs may have impacted electricity prices regarding estimation results for the first phase of the eu ets about 42 of estimated pass through rates appear to be statistically significant while only one third of them are statistically different from zero in the second phase we try to improve those results by proposing alternative estimates based on the eu ets compliance periods

sectors under scrutiny evaluation of indicators to assess the risk of carbon leakage in the uk and germany one of the central debates surrounding the design of the european union emissions trading scheme is the approach to address carbon leakage concerns correctly identifying the economic activities exposed to the risk of carbon leakage represents the first step in mitigating the risk effectively this paper assesses the robustness of the quantitative assessment criteria used by the european commission for phase 3 for example we apply the criteria to data for uk and germany and compare the results with the commissions assessment conducted at the aggregated eu level this reveals that sectors exposure risk to carbon leakage can vary across different member states due to differences in production processes technologies and fuel mix process emissions recycling rate differences product mix differences sector classification statistical boundaries activity allocation differences and finally difference in data quality overall we find that relative carbon intensity of sectors measured as cost increase relative to gross value added provides a robust metric the analysis also highlights the importance of using high quality and disaggregated data for this assessment

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

genuine saving and positional externalities much evidence suggests that people are concerned with their relative consumption yet positional externalities have so far been ignored in savings based indicators of sustainable development this

conspicuous leisure optimal income taxation when both relative consumption and relative leisure matter previous studies on public policy under relative consumption concerns have ignored the role of leisure comparisons this paper considers a two type optimal nonlinear income tax model where people care both about their relative consumption and their relative leisure increased consumption positionality typically implies higher marginal income tax rates for both the high ability and the low ability type whereas leisure positionality has an offsetting role however this offsetting role is not symmetric concern about relative leisure implies a progressive income tax component i e a component that is larger for the high ability than for the low ability type moreover leisure positionality does not modify the policy rule for public good provision when the income tax is optimally chosen

long term trends in fair and unfair inequality in the united states abstractthis article analyses the microeconomic sources of wage inequality in the united states from 1967 2012 decomposing inequality into factors categorized by degree of personal responsibility education explains over twice as much of inequality today as 45 years ago however neither hours worked nor education industry marital status or geographical location can explain the rise in income inequality in fact unfair inequality income disparity derived from non responsibility factors has risen faster than fair inequality income disparity derived from responsibility factors regardless of the set of variables chosen as fair sources of inequality we further examine income inequalities within gender and racial groups finding substantial heterogeneity overall using micro data to understand the sources of inequality and how these changes over time can provide better information for policymakers motivated to combat rising inequality

diversification and its discontents idiosyncratic and entrepreneurial risk in the quest for social status social status concerns influence investors decisions by driving a wedge in attitudes toward aggregate and idiosyncratic risks i model such concerns by emphasizing the desire to get ahead of the joneses which implies that aversion to idiosyncratic risk is lower than aversion to aggregate risk the model predicts that investors hold concentrated portfolios in equilibrium which helps rationalize the small premium for undiversified entrepreneurial risk in the model status concerns are more important for wealthier households consequently these households own a disproportionate share of risky assets particularly private equity and experience greater volatility of consumption consistent with empirical evidence diversification and risk sharing are fundamental principles of modern finance and macroeconomics however empirical evidence suggests that household portfolios are poorly diversified with many people reporting substantial holdings of a single stock for the wealthiest households large shares in closely held businesses constitute a particularly important source of risk e g heaton and lucas 2000a it is not surprising that entrepreneurs bear substantial undiversified risk since it is important for mitigating moral hazard and or adverse selection problems yet from a standpoint of portfolio theory entrepreneurship does not appear to be well compensated implying that many investors are willing to take poorly rewarded risks despite the availability of superior investment opportunities such as public equity that earns a large risk premium e g moskowitz and vissing j0rgensen 2002 hall and woodward 2007

individual well being in a dynamic perspective this paper explores the determinants of individual well being as measured by self reported levels of satisfaction with income making full use of the panel data nature of the german socio economic panel we provide empirical evidence for well being depending on absolute and on relative levels of income in a dynamic framework this finding holds after controlling for other influential factors in a multivariate setting the main novelty of the paper is the consideration of dynamic aspects individual s own history as well as the relative income performance with respect to the others living in the society under analysis do play a major role in the assessment of well being
