microstructure noise realized variance and optimal sampling a recent and extensive literature has pioneered the summing of squared observed intra daily returns realized variance to estimate the daily integrated variance of financial asset prices a traditional object of economic interest we show that in the presence of market microstructure noise realized variance does not identify the daily integrated variance of the frictionless equilibrium price however we demonstrate that the noise induced bias at very high sampling frequencies can be appropriately traded off with the variance reduction obtained by high frequency sampling and derive a mean squared error mse optimal sampling theory for the purpose of integrated variance estimation we show how our theory naturally leads to an identification procedure which allows us to recover the moments of the unobserved noise this procedure may be useful in other applications finally using the profits obtained by option traders on the basis of alternative variance forecasts as our economic metric we find that explicit optimization of realized variance s finite sample mse properties results in accurate forecasts and considerable economic gains copyright 2008 wiley blackwell

a model of the it products in fashion one of the characteristics of the fashion marketplace is the unpredictability and apparent randomness of fashion hits another one is the information asymmetry among consumers in this paper we consider fashion as a means consumers use to signal belonging to a higher social rank and propose an analytical model of fashion hits in the presence of competition and consumers who can coordinate on which product to use we show that consistent with the observed market phenomenon in equilibrium consumer coordination involves randomization between products chosen i e in randomness of fashion hits analyzing optimal consumer choice we find that whenever low type consumer demand for a product is positive a price increase results in a higher probability of high type consumers choosing this product but lower low type consumer demand we also show that although high type consumers may prefer higher prices that would lead to complete separation of the high and the low type consumers through product use in equilibrium firms always price as to attract positive demand from low type consumers the equilibrium price and profits turn out to be nonmonotonic in the low type consumer valuation of being recognized as belonging to a higher social rank equilibrium profits first increase and then decrease in this valuation

status seeking income taxation and efficiency abstract it is well known that status seeking produces distortions in consumption competition to achieve status leads to over consumption of those goods which confer status it has been found that taxing such goods may even lead to pareto improvements in this paper we extend a model of status which relies on a signalling equilibrium approach to include the individual labour supply decision and an income tax we show that a pareto improving income tax can exist even with the simplest tax benefit scheme a number of results follow the model is extended to a two period analysis to accommodate the reputation building element of status achievement without altering the conclusions

conspicuous consumption and sophisticated thinking consumers purchase conspicuous goods to satisfy not only material needs but also social needs such as prestige in an attempt to meet these social needs producers of conspicuous goods like cars perfumes and watches highlight the exclusivity of their products in this paper we propose a monopoly model of conspicuous consumption using the rational expectations framework and then examine how purchase decisions are affected by the desire for exclusivity and conformity we show that snobs can have an upward sloping demand curve but only in the presence of consumers who are weakly followers laboratory tests lend support for this model prediction and for the rational expectations framework the experimental results suggest that subjects used some degree of sophisticated thinking to arrive at their first period decisions their behavior in the subsequent trials however can be adequately captured by a purely adaptive learning mechanism we discuss the implications of consumer learning for optimal dynamic pricing policy by a monopolist

explaining fashion cycles imitators chasing innovators in product space abstract this paper considers the problem of a fashion trend setter confronting an imitator who can produce the same product at lower cost a one dimensional product space is considered which is an abstraction of the key attribute of some consumer good three broad strategies can be optimal for the fashion leader 1 never innovate which milk profits from the initially advantageous position but ultimately concede the market without a fight 2 innovate once but only once which just temporarily defers conceding the market 3 cycle infinitely around product space never letting the imitator catch up and capture the market sometimes the cycles start immediately sometimes the innovator should wait for a time before beginning the cycles the optimal solution exhibits strong state dependency with so called skiba curves separating regions in state space where various of these strategies are optimal there are even instances of intersecting skiba curves in most cases analytical expressions can be stated that characterize these skiba curves

commonality in product design cost saving valuation change and cannibalization abstract offering a variety of products is important for a firm to attract different consumer segments however high product variety increases production and distribution costs modular product design and parts commonality are approaches used to counter this trend in cost and still offer a variety of products this paper develops a model to examine when modular products should be introduced and how much modularity to offer the model looks at a market consisting of a high segment and a low segment customers choose the product that maximizes their surplus which is defined as the product s utility minus its price presence of commonality affects the utility of a product greater commonality decreases production cost but makes the products more indistinguishable from one another this makes the product more desirable for the low segment but less desirable for the high segment the firm s objective is to design the products and set the prices so as to maximize its profit

street crime and street culture a model shows how reputation concerns can support widespread street crime a street culture where the direct incentives for such behavior are weak there are social benefits to street reputations but those benefits are dominated when reputation concerns draw into crime those who obtain no direct gain from it the model matches facts about violent crime that a standard model cannot easily explain including low monetary returns disproportionate victimization of the young and poor and high variance in rates across small distances the model generates novel implications for policy and social science including a negative effect of social capital

status goods experimental evidence from platinum credit cards this paper provides novel evidence on status goods using a series of field experiments with an indonesian bank that markets platinum credit cards to high income customers in a first experiment the paper shows that demand for the platinum card greatly exceeds demand for a nondescript control product with identical benefits suggesting demand for the pure status aspect of the card transaction data reveal that platinum cards are more likely to be used in social contexts implying social image motivations combining price variation with information on the use of the card sheds light on the magnitude of the demand for social status a second experiment provides evidence of positional externalities from the consumption of these status goods the final experiment shows that increasing self esteem causally reduces demand for status goods this suggests that part of the demand for status is psychological in nature and that social image is a substitute for self image

evaluating the magnitude and the stakes of peer effects analysing science and math achievement across oecd what follows is an exercise aimed at estimating peer effects impact on science and math test scores of secondary school students surveyed in 1995 by the international education agency across oecd countries it is also to discuss their importance for educational policy particularly regarding the highly sensitive issue of ability grouping using this unique international database this study assesses the magnitude of the peer effect relative to more traditional inputs referring to education policy stakes we control for the presence of increasing or decreasing return this study also checks for cross effects in order to determine whether peer effects matter more to low or high ses pupils and whether their final impact on achievement is affected by the underlying level of heterogeneity within the group using a methodology which a priori accounts for the clustering of the data within countries and schools classrooms i e fixed random effect or hierarchical model our analysis indicates that peer effects are strong determinants of both math and science achievement relative to individual ses and other school inputs the presence of increasing of decreasing returns is not obvious but we find systematic evidence that low ability pupils are more sensitive to peer group characteristics by contrast this study also find that for a given level of the peer effect higher heterogeneity comes at a certain cost in brief these results provide no systematic evidence regarding grouping policies

how does peer pressure affect educational investments when effort is observable to peers students may try to avoid social penalties by conforming to prevailing norms to test this hypothesis we first consider a natural experiment that introduced a performance leaderboard into computer based high school courses the result was a 24 percent performance decline the decline appears to be driven by a desire to avoid the leaderboard top performing students prior to the change those most at risk of appearing on the leaderboard had a 40 percent performance decline while poor performing students improved slightly we next consider a field experiment that offered students complimentary access to an online sat preparatory course sign up forms differed randomly across students only in whether they said the decision would be kept private from classmates in nonhonors classes sign up was 11 percentage points lower when decisions were public rather than private honors class sign up was unaffected for students taking honors and nonhonors classes the response depended on which peers they were with at the time of the offer and thus to whom their decision would be revealed when offered the course in a nonhonors class where peer sign up rates are low they were 15 percentage points less likely to sign up if the decision was public but when offered the course in an honors class where peer sign up rates are high they were 8 percentage points more likely to sign up if the decision was public thus students are highly responsive to their peers are the prevailing norm when they make decisions

adverse selection without single crossing monotone solutions abstract the single crossing assumption simplifies the analysis of screening models as local incentive compatibility becomes sufficient for global incentive compatibility if single crossing is violated global incentive compatibility constraints have to be taken into account this paper studies monotone solutions in a screening model that allows a one time violation of single crossing the results show that local and non local incentive constraints distort the solution in opposite directions therefore the optimal decision might involve distortions above as well as below the first best decision furthermore the well known no distortion at the top property does not necessarily hold the results show that the decision can even be distorted above first best for all types sufficient conditions for existence strict monotonicity and continuity of the solution are presented a new necessary condition satisfied by such solutions is found an algorithm based on this condition can calculate continuous and strictly monotone solutions

longer term effects of head start specially collected data on adults in the panel study of income dynamics are used to provide evidence on the longer term effects of head start an early intervention program for poor preschool age children whites who attended head start are relative to their siblings who did not significantly more likely to complete high school attend college and possibly have higher earnings in their early twenties african americans who participated in head start are less likely to have been booked or charged with a crime there is some evidence of positive spillovers from older head start children to their younger siblings language en

why do people care about social status abstract this paper shows that complementary interaction can induce people to care about social status because it serves as a signal of non observable abilities there is a unique separating equilibrium in which everyone cares about social status in this equilibrium a person s social status perfectly reveals his abilities and everyone matches with a person of like ability the analysis shows that people s instrumental concern for social status has important welfare and policy implications indeed peoples efforts to keep up with the joneses may be welfare enhancing

macroeconomic implications of conspicuous consumption a sombartian dynamic model this chapter presents a dynamic general equilibrium model in which consumers have status preference i investigate the manner in which capital accumulation is impeded by conspicuous consumption a la corneo and jeanne j public econ 66 55 71 1997a following the literature social norms are given as either bandwagon type or snob type i then show that when the economy is characterized by a bandwagon type social norm capital accumulation exhibits interesting patterns those patterns include for example an oscillating convergence path the rise of the economy feeds its decay through conspicuous consumption and that decay suppresses conspicuous consumption and engenders prosperity as predicted by sombart liebe luxus und kapitalismus reprinted 1967 deutscher taschenbuch verlag munchen 1912

optimal income tax in the presence of status effects abstract the existence of distortions from individuals competing to attain social status by using consumption signals justifies some measure of income tax as a counter acting distortion the question posed here is whether it also constitutes a reason for a more progressive income tax schedule the answer is found to be broadly negative if progressiveness is interpreted as a more convex tax schedule unless the rich are more concerned with status seeking than the poor on the other hand status seeking makes the optimal tax schedule steeper so that redistribution is increased essentially the analysis of status seeking based on a signaling approach confirms and strengthens the existing view of an optimal tax schedule and can be incorporated into the diamond american economic review 88 1998 83 95 approach

does school tracking affect equality of opportunity new international evidence this paper investigates whether the interaction between family background and secondary school tracking affects human capital accumulation a widely shared view is that more tracking reinforces the role of parental privilege and thereby reduces equality of opportunities this may occur for several reasons including peer effects more talented students are gathered together teacher sorting better teachers prefer teaching better students differences in curricula academic oriented schools like the german gymnasium the french lycee the british grammar school or the italian liceo teach abilities that increase the probability of entering college and or differences in resource endowment compared to the current literature which focuses on early outcomes such as test scores at 13 and 15 years old we look at later outcomes including literacy dropout rates college enrolment employability and earnings while we do confirm the common view that school tracking reinforces the impact of family background when looking at educational attainment and labour market outcomes we do not confirm the same results when studying its impact on literacy and on the job training overall school tracking has an ambiguous effect in our sample of countries on the one hand and consistently with the previous literature tracking has a detrimental impact on educational attainment because it prevents some individuals from further progressing to the tertiary level of education the diversion effect on the other hand the curricula offered in vocational schools seem more effective in promoting further training and adult competences the specialization effect thereby reducing the impact of parental background on these two outcomes thus reducing the extent of student tracking either by raising the age of first selection or by reducing the number of tracks available may be appropriate for increasing intergenerational mobility in educational attainment but may increase social exclusion for people from disadvantaged backgrounds giorgio brunello and daniele checchi

a test of conspicuous consumption visibility and income elasticities abstract this paper shows that consistent with a signaling by consuming model a la veblen income elasticities can be predicted from the visibility of consumer expenditures we outline a stylized conspicuous consumption model where income elasticity is endogenously predicted to be higher if a good is visible and lower if it is not we then develop a survey based measure of expenditure visibility ranking different expenditures by how noticeable they are to others finally we show that our visibility measure predicts up to one third of the observed variation in elasticities across consumption categories in u s data

celebrations as social investments festival expenditures unit price variation and social status in rural india festival expenditures amount to over 15 per cent of a household s annual expenditures in rural india yet they have never been studied by economists this article uses both qualitative and quantitative data from a case study of three south indian villages to show that festivals are important public goods in the village but neither a pure entertainment motive nor an altruistic desire to contribute to a public event seems to explain their size households which spend money on festivals everything else held equal are able however to generate tangible rewards lower prices on food higher social status and more invitations to meals from other families this indicates that active participation in festivals generates private economic and social returns which help resolve a potential free rider problem the evidence is consistent with the notion that festivals serve as mechanisms by which communities build social networks

assessing students equality of opportunity in oecd countries the role of national and school level policies abstractthis article analyses the relationship between equality of opportunity and the characteristics of the educational system jointly considering country and school level policies because school social environment represents a fundamental channel in shaping educational opportunities we consider all policies recorded in pisa 2012 dataset that affect the sorting of students to schools we show that including sorting policies enriches the explanation of the socio economic gradient that is the association between students performances and parental background with respect to previous studies including only country level features the negative impact of early tracking on equality of opportunity is overvalued without including other sorting policies while grouping students within school by ability increases the socio economic gradient and a greater students heterogeneity in the school reduces the gradient

waves in consumption with interdependence among consumers this paper presents a model to analyze the development of consumption patterns when there are social interactions among consumers in particular a consumer in this model recognizes three reference groups a peer group of similar consumers with whom the consumer wishes to share consumption activities a distinction group from which the consumer wishes to distinguish him or herself and an aspiration group to which the consumer does not belong but wishes that he she did and with whom the consumer would like to share consumption activities the interplay of aspiration and distinction can lead to waves in consumption these can happen when for example the avant garde consumption of up market pioneers is copied by other types of consumer as the latter aspire to emulate the former the former in turn seek to distinguish themselves from these unwelcome companions by varying their consumption in consequence a particular consumption activity may start up market an then gradually proceed down the social spectrum more complex patterns with continuing cycles in consumption can also be found the paper argues that this model is not only applicable to the consumption behaviour of an elite or would be elite but is relevant in a wide range of consumption settings

pecuniary emulation inequality and growth abstract we study a two class growth model in which agents care about both consumption and the social perception of their wealth rank the latter determines the social status enjoyed by agents social perceptions are based upon noisy signals of wealth and in equilibrium there is incomplete separation of classes the steady growth rate of the economy increases with the full information status differential between classes and contrary to the growth model without status it is affected by the initial level of wealth inequality both too much equality and too much inequality are detrimental to economic growth

portfolio management using realized covariances evidence from brazil abstract it is often argued that intraday returns can be used to construct covariance estimates that are more accurate than those based on daily returns however it is still unclear whether high frequency data provide more precise covariance estimates in markets more contaminated from microstructure noise such as higher bid ask spreads and lower liquidity we address this question by investigating the benefits of using high frequency data in the brazilian equities market to construct optimal minimum variance portfolios we implement alternative realized covariance estimators based on intraday returns sampled at alternative frequencies and obtain their dynamic versions using a multivariate garch framework our evidence based on a high dimensional data set suggests that realized covariance estimators performed significantly better from an economic point of view in comparison to standard estimators based on low frequency close to close data as they delivered less risky portfolios

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

globalization and household saving is there a link abstractthis article proposes that globalization can affect household saving in the long run in a number of ways social interactions between different cultures can induce value changes which can result in shifts in consumption and saving behaviour international trade allows consumers to have easier access to status goods stimulating consumption and dampening saving extending from veblen s conspicuous consumption theory saving may also decrease when globalization leads to greater population mobility and fosters urbanization thus enhancing the importance of consumption as a way to display wealth in addition financial globalization reduces credit constraints and allows households to save less using cross country data from the united nations un the oecd and other sources this article finds evidence that household saving declines as globalization deepens especially in the social and cultural dimensions

optimal pricing of a conspicuous product during a recession that freezes capital markets abstract this paper considers the problem of how to price a conspicuous product when the economy is in a recession that disrupts capital markets a conspicuous product in this context is a luxury good for which demand is increasing in brand image brand image here means the ability of a consumer to impress observers by conspicuously displaying consumption of the good brand image is built up when the good is priced high enough to make it exclusive and eroded if the good is discounted recession is modeled as having two effects it reduces demand and it freezes capital markets so borrowing is not possible in pricing the conspicuous product the firm faces the following trade off reducing price helps maintain sales volume and cash flow in the face of reduced demand but it also damages brand image and thus long term demand the paper analyzes the firm s pricing policy facing scenarios of mild intermediate and severe recessions while taking the threat of bankruptcy into account for an intermediate recession the optimal solution is history dependent the results have implications for policy interventions in capital markets and for timing of mergers and acquisitions

the effects of lottery prizes on winners and their neighbors evidence from the dutch postcode lottery each week the dutch postcode lottery pcl randomly selects a postal code and distributes cash and a new bmw to lottery participants in that code we study the effects of these shocks on lottery winners and their neighbors consistent with the life cycle hypothesis the effects on winners consumption are largely confined to cars and other durables consistent with the theory of in kind transfers the vast majority of bmw winners liquidate their bmws we do however detect substantial social effects of lottery winnings pcl nonparticipants who live next door to winners have significantly higher levels of car consumption than other nonparticipants

ability tracking school competition and the distribution of educational benefits abstract to study the effects of ability grouping on school competition we develop a theoretical and computational model of tracking in public and private schools we examine tracking s consequences for the allocation of students of differing abilities and income within and between public and private schools private schools tend to attract the most able and wealthiest students and rarely track in equilibrium public sector schools can maximize attendance by tracking students public schools retain a greater proportion of higher ability students by tracking but lose more wealthy lower ability students to the private sector consequently socioeconomic status is a predictor of track assignment in public schools for the entire population public sector tracking has small aggregate effects on achievement and welfare but results in significant redistribution from lower to higher ability students

on limiting the market for status signals abstract in many societies individuals care how others view them in their efforts to impress such individuals engage in consumption signals which attempt to establish higher levels of status than their true status type this leads to an inefficiency which offers the possibility of a pareto improving tax policy the impacts of tax policy and benefits on the signalling equilibrium are considered

pricing of conspicuous goods a competitive analysis of social effects abstract social needs play an important role in the purchase of conspicuous goods in this article the authors extend traditional economic models to accommodate social needs such as desire for uniqueness and conformism and examine their implications for pricing conspicuous goods first in the context of a duopoly the authors identify the conditions under which the desire for uniqueness can increase demand among some consumers as the price of a product increases second the authors show that though the desire for uniqueness leads to higher prices and firm profits a desire for conformity leads to lower prices and profits third the authors find that consumers purchase high quality products not because of their desire for uniqueness but despite it finally marketers of conspicuous goods may find it beneficial not to emphasize the functional differences among their products when the need for uniqueness is high in a laboratory test the authors find support for the claim that demand for a product amo

social limits to redistribution in many countries equality of political rights including the right to vote over taxes and transfers goes along with substantial inequality of economic conditions this observation lies at the root of one fundamental issue in political economy one about the factors that limit the extent of redistribution in democracies the conventional economic wisdom on this issue can roughly be summarized by two arguments firstly redistributive taxation may be limited by various kinds of incentive costs of taxation as e g in james a mirrlees 1971 kevin w s roberts 1977 dennis n epple and thomas romer 1991 and thomas piketty 1995 secondly redistribution may be dampened by the lobbying activity of high income groups and by various imperfections inherent to the political process that determines the tax system as e g in gary s becker 1983 and john e roemer 1995 while both arguments offer illuminating insights into the phenomenon of redistribution they are also based on a very crude description of human behavior one which ignores social motivations of action both in the economic and the political sphere the present paper develops an explanation that takes such motivations into account specifically it shows that limits to redistribution may arise when economic inequality has an informational value for social decisions our approach is based upon the following observation many goods and decisions that heavily affect an individual s quality of life are not allocated or made through markets but through social interactions thomas scitovsky 1976 for instance although people have strong preferences over how they are treated by others and over whom they mate with these things are not the object of market transactions a number of sources of satisfaction like conversation dinners and parties playing with others and being observed and admired are nonmarket goods for which a keen social competition between individuals often develops as shown by harold cole et al 1992 the existence of social rather than market competition for some goods can endogenously generate a concern for relative position in the income distribution when information about relative income is private individuals become interested in the observable consumption differentials between them and their social competitors since consumption differentials are influenced by redistributive taxation the political attitudes of people toward redistribution will be shaped by its expected impact on social competition in some identifiable environments this concern for social success may be the crucial factor that limits the extent of redistribution desired by a majority of voters specifically while the middle class may obtain economic benefits from a large amount of redistributive taxation it may oppose an equalization of living standards since this would harm its social success the fear of losing social status in favor of the poor induces the middle class to enter a political alliance with the rich which supports conservative taxation programs in the sociological literature scholars of voting behavior have often suggested that the need for social recognition plays a crucial role in shaping political attitudes seymour m lipset 1967 pointed out that white collar workers tend to be socially valued similarly as those higher in the system and although their income may be only slightly larger than that of manual workers white collars are much more likely to corneo department of economics university of osnabruck rolandstrasse 8 d 49069 osnabruck germany cesifo munich and cepr london gruner department of economics university of mannheim d 68131 mannheim germany iza bonn and cepr london we would like to thank emmanuelle auriol dieter bos peter funk mike hout olivier jeanne peter jonas georg noldeke thomas piketty regis renault john roemer jens weidmann and three anonymous referees for insightful comments and suggestions we have also benefited from the comments of participants at workshops and conferences in barcelona bonn davis jena maastricht magdeburg mannheim montreal munich rotterdam silvaplana tel aviv tilburg toulouse and warwick at which we presented earlier versions of this work financial support from the deutsche forschungsgemeinschaft sfb 303 at the university of bonn is gratefully acknowledged

dynamic models of religious conformity and conversion theory and calibrations abstract this paper develops overlapping generations models to explain and simulate changes in the proportion of secular and religious people the church is modeled as generating an externality associated with conformity enhancing education observed changes in the number of nonbelievers are explained by different birth rates among secular and religious parents and the relative proportion of young nonconformists calibrations for the conformity rates among secular and religious people show that the observed long run increase in the difference between percentage of secular people in europe and the united states can be attributed to lower conformity rates prevailing in europe

design innovation and fashion cycles a model of fashion cycles is developed in which designs are used as a signaling device in a dating game a monopolist periodically creates a new design over time the price of the design falls as it spreads across the population once sufficiently many consumers own the design it is profitable to create a new design and thereby render the old design obsolete this paper gives conditions under which all consumers would be better off by banning the use of fashion competition among designers may lead to less frequent changes in fashion and to higher prices than monopoly copyright 1995 by american economic association

multivariate high frequency based volatility heavy models this paper introduces a new class of multivariate volatility models that utilizes high frequency data we discuss the models dynamics and highlight their differences from multivariate garch models we also discuss their covariance targeting speci cation and provide closed form formulas for multi step forecasts estimation and inference strategies are outlined empirical results suggest that the heavy model outperforms the multivariate garch model out of sample with the gains being particularly signi cant at short forecast horizons forecast gains are obtained for both forecast variances and correlations

promotions and product pricing parsimony versus veblenesque demand the veracity of the parsimonious law of demand has long been challenged by analyses of the veblen effect and prestige pricing backward bending demand curves often attend discussions of conspicuous consumption probing the sociological and psychological intricacies of potential consumer interdependencies scholars in economics and marketing have overlooked mundane product promotions for a monopolistic firm we formalize the relationship between the optimal price quantity combination and the thoroughness of product promotions iterating toward the profit maximizing thoroughness of product promotion gives rise to a backward bending price quantity locus challenges to the law of demand that ignore product promotions are thereby undercut

if you tourist behave irrationally i ll find you abstract when departures from rational behavior can potentially be expected modeling should allow for their identification and their quantification in this regard prices in tourism might have effects that may not be as apparent as economic theory predicts this article incorporates the sticker shock formulation into the mixed logit model without imposing consistency with consumer theory to accommodate any possible positive or negative price effects by allowing the parameters of price and sticker shock term to take any value negative or positive we detect abnormal behaviors in the tourist demand not only is the negative relationship between price and demand inverted for some people but also some tourists might be willing to accept higher than expected prices the non well behaved groups shares are estimated

equity and efficiency in human capital investment the local connection a general model of community formation and human capital accumulation with social spillovers and decentralized school funding is used to analyse the causes of economic segregation and its consequences for equity and efficiency significant polarization arises from minor differences in endowments preferences or access to capital markets this makes income inequality more persistent across generations but the same need not be true for wealth equilibrium stratification tends to be excessive resulting in low aggregate surplus whether state equalization of school resources can remedy these problems hinges on how purchased social and family inputs interact in education and in mobility decisions

social identity and preferences social identities prescribe behaviors for people we identify the marginal behavioral effect of these norms on discount rates and risk aversion by measuring how laboratory subjects choices change when an aspect of social identity is made salient when we make ethnic identity salient to asian american subjects they make more patient choices when we make racial identity salient to black subjects non immigrant blacks but not immigrant blacks make more patient choices making gender identity salient has no effect on intertemporal or risk choices

contests for ranks experimental evidence we use experiments to analyze multiple dimensions of the relationship between rank incentives and individual performance in our experiment i rank is defined as subjects relative position in their group based on their performance in a real effort task and ii subjects earnings are independent of their performance we find that any rank incentive improves mean performance than no rank incentive and this result is independent of the group size in the large group the mean performance increases strictly in all except at the highest rank incentive but in the small group the mean performance increases weakly in rank incentives finally the mean performance is significantly higher in the large than in the small group because of a higher prestige effect in additional treatments in which we do not reveal the identity of the statusprize winners we find that average performance is identical to that in the baseline treatment without any status prizes the last result signifies the important role that public revelation plays to enhance the strength of status the results are important for managerial practices

economics and identity this paper considers how identity a person s sense of self affects economic outcomes we incorporate the psychology and sociology of identity into an economic model of behavior in the utility function we propose identity is associated with different social categories and how people in these categories should behave we then construct a simple game theoretic model showing how identity can affect individual interactions the paper adapts these models to gender discrimination in the workplace the economics of poverty and social exclusion and the household division of labor in each case the inclusion of identity substantively changes conclusions of previous economic analysis

understanding the solar home price premium electricity generation and green social status this study uses a large sample of homes in the san diego area and sacramento california area to provide some of the first capitalization estimates of the sales value of homes with solar panels relative to comparable homes without solar panels although the residential solar home market continues to grow there is little direct evidence on the market capitalization effect using both hedonics and a repeat sales index approach we find that solar panels are capitalized at roughly a 3 5 premium this premium is larger in communities with a greater share of college graduates and of registered prius hybrid vehicles

multi period pricing in the presence of competition and social influence abstract this paper examines single and dynamic pricing policies of two competing firms over two periods in the presence of social influence assuming two firms adopt the same pricing policy we find that under either pricing policy firm profits always decrease with the degree of social influence firms prefer dynamic pricing policy when social influence is either relatively weak or sufficiently strong for firms under dynamic pricing policy to set zero prices in the first period otherwise single pricing policy is more preferable the conclusions are similar when the market size varies over periods except that dynamic pricing policy is always more profitable if the market size in period 2 is sufficiently large we have further compared the two pricing policies with posted pricing policy the results show that dynamic pricing policy dominates when social influence is relatively weak while posted pricing policy dominates when social influence is sufficiently strong because of the synergy between social influence and the reference price effect finally when each firm freely chooses either single or dynamic pricing policy we find that if the degree of social influence is relatively small two asymmetric equilibria exist where two firms adopt different pricing policies if the degree of social influence is very large however the unique equilibrium is both firms adopting dynamic pricing policy these findings provide important implications for firms to make more informed pricing decisions in an increasingly competitive environment with strong social influence

equilibrium and inefficiency in a community model with peer group effects public service output depends on input expenditures on own personal characteristics and on the characteristics of the other residents in the community the peer group effect in a community model with public expenditures set by voting with migration between communities and with land price differentials capitalization it is shown that communities may become heterogeneous in composition and second best inefficient this equilibrium occurs when the peer group effect is neither too strong nor too weak the inefficiency arises because an externality is created by migration the land price differential does not play the part of the price of the better peer group but of a transfer payment

capital stock management during a recession that freezes credit markets abstract this paper considers the problem of how to price a conspicuous product while maintaining liquidity during a recession which both reduces demand and freezes credit markets reducing price would help maintain cash flow but low prices can erode brand image and hence long term sales the paper extends earlier work of the same authors by explicitly deriving a firm s optimal cash management behavior taking into account that a too low cash level results in bankruptcy there are different sets of initial conditions for which qualitatively different solution trajectories are optimal we distinguish mild and severe recessions with mild recessions bankruptcy can be avoided for sure when the brand image is large enough in case the recession is of intermediate strength it can be optimal to throttle forward then back how aggressively one spends down cash reserves with the associated state constraint alternately being non binding binding non binding then binding in such a way that the firm ceases operation

what is middle class about the middle classes around the world we expect a lot from the middle classes jim frederick writing in time magazine in 2002 stated china s burgeoning middle class holds the key to the future of the country in a more academic vein easterly 2001 concludes based on a comparison of a large number of countries that countries that have a larger middle class tend to grow faster at least if they are not too ethnically diverse in another article birdsall graham and pettinato 2000 rue the shrinking of the middle class the backbone of both the market economy and of democracy in most advanced societies in the face of burgeoning globalization the economic historian david landes writing about the wealth and poverty of nations 1998 explains england s early ascendancy in terms of the great english middle class of the eighteenth and nineteenth centuries of course there is nothing new about this faith in the middle class it follows a long line of theorizing going back at least to max weber 1905 at least three distinct arguments are traditionally made in one new entrepreneurs armed with a capacity and a tolerance for delayed gratification emerge from the middle class and create employment and productivity growth for the rest of society for a formalization of this argument see acemoglu and zilibotti 1997 in a second perhaps more conventional view the middle class is primarily a source of vital inputs for the entrepreneurial class it is their middle class values their emphasis on the accumulation of human capital and savings that makes them central to the process of capitalist accumulation for example doepke and zilibotti 2005 2007 the third view a staple of the business press emphasizes the middle class consumer the consumer who is willing to pay a little extra for quality in this view the middle class demand for quality consumer goods feeds investment in production and marketing which in turn raises income levels for everyone murphy shleifer and vishny 1989 1 this essay asks what we should make of these arguments in the context of today s developing countries starting from data on patterns of consumption and investment by the middle class we look for what is distinct about the global middle class especially when compared to the global poor defined as those whose per capita daily consumption valued at purchasing power parity exchange rates is below 2 a day who were the subject of a previous essay in this journal banerjee and duflo 2007b in particular is there anything special about the way the middle class spend their money earn their incomes or bring up their children

social status entry and predation the case of british shipping cartels 1879 1929 the authors incorporate social status and regional affiliation two variables of central sociological interest into an economic analysis of entry and predation they build on scott morton s 1997 examination of entry and predation in the merchant shipping industry and examine whether the social status of an entrant owner impacts on the predation behavior of the incumbent cartels they find that high social status entrants are significantly less likely 40 to be preyed upon than the low social status entrants they discuss several interpretations of this result subsequent analysis supports the hypothesis that cartel members use social status as an indicator of an entrant s propensity to be a cooperative cartel participant

crime and conspicuous consumption we study how property crime distorts consumption decisions using an incomplete information model we argue that consuming conspicuous goods reveals information to criminals seeking bountiful victims and increases the likelihood of being victimized thus property crime reduces the consumption of visible goods even when these cannot be directly stolen but simply carry information about a potential victim s wealth we exploit the large decline in property crime in the u s during the 90s to test this mechanism using data from the u s consumer expenditure survey from 1986 to 2003 we find that households located in states experiencing sharper reductions in property crime increased significantly their consumption of visible goods even when these goods are not generally stolen both in absolute terms and relative to other consumption goods our findings hold when we instrument the decline in property crime during the 90s using a variety of strategies

modelling and forecasting multivariate realized volatility summary this paper proposes a methodology for dynamic modelling and forecasting of realized covariance matrices based on fractionally integrated processes the approach allows for flexible dependence patterns and automatically guarantees positive definiteness of the forecast we provide an empirical application of the model which shows that it outperforms other approaches in the extant literature both in terms of statistical precision as well as in terms of providing a superior mean variance trade off in a classical investment decision setting copyright 2010 john wiley sons ltd

signalling inequality and the social structure this paper proposes a theory of endogenous transmission of social status through signalling in the labour market a signalling game is analysed in which education acting as a signalling good determines one s position in society the economy s degree of inequality is shown to be a determinant of whether a society is aristocratic where high income is the source of social standing or meritocratic bestowing status on high ability each social structure shows a different balance between production efficiency and social factors such as equality or mobility

conspicuous consumption snobbism and conformism abstract we develop a model in which consumers purchase a conspicuous good in order to signal high income and thereby achieve greater social status in equilibrium the signalling value of conspicuous consumption depends in an identifiable way on the number of consumers and consumer behaviour is characterized by either snobbism or conformism the market demand curve for the conspicuous good may exhibit a positive slope if consumers are conformist we derive some unconventional policy implications concerning the taxation of luxuries and the voluntary provision of public goods

educational reform ability and family background in this paper we evaluate the impact of a major school reform that took place in the 1950s in sweden on educational attainment and earnings the reform which has many common elements with reforms in other european countries including the uk consisted of increasing compulsor schooling imposing a national curriculum and abolishing selection by ability into academic and non academic streams at the age of 12 comprehensive school reform our data combines survey data with administrative sources we find that the reform increased both the educational attainment and the earnings of children whose fathers had just compulsory education however the earnings of those with educated parents declined possibly because of a dilution of quality at the top end of the education levels the overall effect of the reform was however positive

school tracking and intergenerational income mobility evidence from the finnish comprehensive school reform abstract this paper estimates the effect of a major education reform on intergenerational income mobility the finnish comprehensive school reform of 1972 1977 replaced the old two track school system with a uniform nine year comprehensive school and shifted the selection of students to vocational and academic tracks from age 11 to age 16 we estimate the effect of this reform on the intergenerational income elasticity using a representative sample of males born between 1960 and 1966 the identification strategy relies on a differences in differences approach and exploits the fact that the reform was implemented gradually across the country during a six year period the results indicate that the reform reduced the intergenerational income elasticity by 23 from the pre reform elasticity of 0 30 to post reform elasticity of 0 23

selling to conspicuous consumers pricing production and sourcing decisions consumers often purchase goods that are hard to find to conspicuously display their exclusivity and social status firms that produce such conspicuously consumed goods such as designer apparel fashion goods jewelry etc often face challenges in making optimal pricing and production decisions such firms are confronted with precipitous trade off between high sales volume and high margins because of the highly uncertain market demand strategic consumer behavior and the display of conspicuous consumption in this paper we propose a model that addresses pricing and production decisions for a firm using the rational expectations framework we show that in equilibrium firms may offer high availability of goods despite the presence of conspicuous consumption we show that scarcity strategies are harder to adopt as demand variability increases and we provide conditions under which scarcity strategies could be successfully adopted to improve profits finally to credibly commit to scarcity strategy we show that firms can adopt sourcing strategies such as sourcing from an expensive production location supplier or using expensive raw materials this paper was accepted by preyas desai and pradeep chintagunta marketing

veblen effects in a theory of conspicuous consumption the authors examine conditions under which veblen effects arise from the desire to achieve social status by signaling wealth through conspicuous consumption while veblen effects cannot ordinarily arise when preferences satisfy a single crossing property they may emerge when this property fails in that case budget brands are priced at marginal cost while luxury brands though not intrinsically superior are sold at higher prices to consumers seeking to advertise wealth luxury brands earn strictly positive profits under conditions that would with standard formulations of preferences yield marginal cost pricing the authors explore factors that induce veblen effects and they investigate policy implications copyright 1996 by american economic association

desire to acquire powerlessness and compensatory consumption three experiments examine how power affects consumers spending propensities by integrating literatures suggesting that a powerlessness is aversive b status is one basis of power and c products can signal status the authors argue that low power fosters a desire to acquire products associated with status to compensate for lacking power supporting this compensatory hypothesis results show that low power increased consumers willingness to pay for auction items and consumers reservation prices in negotiations but only when products were status related the link between powerlessness and compensatory consumption has broad implications both for consumers health and well being and for understanding the psychological state of power

the impact of educational standards on the level and distribution of earnings the goal of this paper is to present the following finding an egalitarian policy maker might prefer higher standards than would a policy maker whose goal was to maximize the sum of earnings the result is based on the observation that if workers are differentiated with respect to ability an increase in educational standards will increase the earnings of both the most able and the least able workers the only workers whose earnings fall are those workers who after the increase fail to continue meeting the standard

status effects and negative utility growth this paper explains the observed stagnation of happiness measures through a growth model in which agents care about conspicuous consumption normal goods confer direct utility while status goods confer utility only at the expense of others firms can improve the quality of both goods through r d the nash equilibrium of the consumer game results in the share of expenditure on status goods increasing with the number of times the status good has been improved as the economy grows resources for innovation are transferred entirely to status good r d the resulting long run rate of utility growth is negative

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

do coffee roasters benefit from high prices of green coffee abstract the german coffee industry has repeatedly made the puzzling statement that it would prefer higher prices of green coffee its main input likewise it supported the maintenance of the coffee tax in this paper an oligopoly model with differentiated products is used to illustrate the possibility of profit raising cost increases the relationship between prices and costs of roasted coffee in germany is estimated and the hypothesis of overshifting is tested in addition the demand for coffee is studied however the empirical analysis does not confirm that increasing costs lead to higher profits alternative explanations for the coffee industry s statements based on long term considerations are also discussed
