growth and inequality in the dual model of development the role of demand factors this paper relates growth and income distribution in the development of a dual economy its originality lies in the fact that the analysis of income inequality uses the whole lorenz curve instead of some summary measures and that the dual economy is represented through a fully specified general equilibrium model conditions for particular shifts in the lorenz curve are derived they mostly involve the income and price elasticities of demand faced by the traditional sector of the economy and suggest that an unambiguous drop in income inequality is somewhat unlikely at the dual stage of development

eco labelling consequences in general equilibrium a graphical assessment international environmental groups propose to implement new standards of forest management through programs that certify producers who meet criteria to enhance biodiversity or sustainability these producers could earn an eco label that identifies their products for consumers we consider whether a market economy might generate feedbacks that produce undesirable side effects as consumers respond to price changes while the general case is ambiguous the theoretical framework shows the potential that certification may lead to a reallocation of land toward less ecologically sustainable uses with the possibility of sufficient impact to diminish global biodiversity or sustainability of forest products

eco labelling by a for profit certifier countervailing power and its consequences for profit certifier s eco labelling is common in industries where firms have some countervailing power on sharing gains from labelling we show that the certification standard for an environmental quality is lowered when firms have strong power a certifier with too low bargaining power will prefer to sell to the best offer rather than bargain this switch in the selling mechanism also thwarts his incentives in setting the standard this is consequential for evaluating policies the dimensions and even signs of welfare changes induced by taxes and subsidies depend upon the mechanism used and ultimately upon firms countervailing power

human capital inequality and economic growth some new evidence this paper provides new measures of human capital inequality for a broad panel of countries taking attainment levels from barro and lee 2001 we compute gini coefficients and the distribution of education by quintiles for 108 countries over five year intervals from 1960 to 2000 using this new cross country data on human capital inequality two main conclusions are obtained first most countries in the world have tended to reduce the inequality in human capital distribution second human capital inequality measures provide more robust results than income inequality measures in the estimation of standard growth and investment equations

targeting capital a cultural economy approach to understanding the efficacy of two anti genetic engineering movements in the late 1990s the british anti genetic engineering ge movement effectively closed britain s market for genetically modified foods while the u s anti ge movement had a negligible impact in seeking to explain the different outcomes of these similar social movements the authors draw upon the global commodity chains gcc literature to extend the understanding of the economic and industry related openings and closures social movements face as they seek to promote social change this analysis not only illustrates the importance of economic structures and organization for movement outcomes but also shows how the economic sphere is culturally constituted in this fashion it broadens the social movement literature s understanding both of the way that political economy matters to movement efficacy and of the way that cultural processes infuse the economic sphere the study advances the gcc literature by showing how gccs are cultural as well as economic constructs

shaming the corporation the social production of targets and the anti sweatshop movement as social movements co evolve with changes in states and markets it is crucial to examine how they make particular kinds of actors into focal points for the expression of grievances and the demand for rights but researchers often bracket the question of why some kinds of organizations are more likely than others to become targets of social movement pressure we theorize the social production of targets by social movements rejecting a simple reflection model to focus on configurations of power and vulnerability that shape repertoires of contention empirically we extend structural accounts of global commodity chains and cultural accounts of markets to analyze the production of targets in the case of the anti sweatshop movement of the 1990s using a longitudinal firm level dataset and unique data on anti sweatshop activism we identify factors that attracted social movement pressure to particular companies firms power and positions strongly shaped their likelihood of becoming targets of anti swea

development and inequality revisited three decades after the seminal article of kuznets 1955 and one decade after the empirical investigation of ahluwalia 1976b the relationship between income inequality and economic developement is still controversial this paper examines the above relationship within a time series cross section framework in a sample of countries which are representative of the non centrally planned economies of the world we use gdp per capita in real un international comparison project dollors as an indicator of a country s level of economic development the results lend support to the kuznets inverse u hypothesis although other factors relfecting the institutional setting of a country are found to affect income inequality significantly during the development process as well similar results are obtained if we exclude developed countries from the sample

public versus private investment in human capital endogenous growth and income inequality in this paper we present an overlapping generations model with heterogeneous agents in which human capital investment through formal schooling is the engine of growth we use simple functional forms for preferences technologies and income distribution to highlight the distinction between economies with public education and those with private education we find that income inequality declines more quickly under public education on the other hand private education yields greater per capita incomes unless the initial income inequality is sufficiently high we also find that societies will choose public education if a majority of agents have incomes below average

environmental quality competition and eco labeling abstract a three stage game of investment environmental quality provision and price competition is developed to study the impact of green technology investment eco labeling in a duopoly model of vertical product differentiation the firms incentives to invest in green technologies depend on their relative cost structure when firms are identical with respect to fixed costs both firms will always invest but if one firm is more efficient in investing then the other firm may or may not invest depending on the level of unit cost of investment quality competition will be tighter when the low quality firm is more efficient and looser when the high quality firm is more efficient in investing socially optimal investment for both firms is always positive but lower than in the duopoly solution in the absence of environmental externalities the quality dispersion chosen by profit maximizing firms may be too high or too low while environmental externalities increase the possibility low quality dispersion that is too low within the market solution finally and importantly ecolabeling can be used as a means of reducing excessive investment and increasing environmental quality that is too low

disclosure strategies for pollution control disclosure strategies which involve public and or private attempts to increase the availability of information on pollution form the basis for what some have called the third wave in pollution control policy after legal regulation the first wave and market based instruments the second wave while these strategies have become common in natural resource settings forest certification and organic farming for example they are less familiar in a pollution control context yet the number of applications in that context is now growing in both oecd and developing countries this survey will review what we know and don t know about the use of disclosure strategies to control pollution and conclude with the author s sense of where further research would be particularly helpful

the economics of rising stars this paper analyzes an occupation in which there is substantial uncertainty about individual performance and past performance is correlated with future outcomes in equilibrium only the young enter the occupation and only the successful stay on the young are numerous and earn incomes well below what their current alternative o ffers success is rare and rewarded highly the implied distribution of earnings must have positive skewness copyright 1988 by american economic association

toward a theoretical model of voluntary overcompliance abstract we explain why some firms voluntarily overcomply with environmental regulation in our model all consumers value environmental quality but differ in their willingness to pay which depends on their income levels publicly available information on environmental performance of firms enables consumers to identify clean firms firms participate in a two stage duopoly game where they first choose their levels of cleaning technology and next engage in price competition the market gets segmented by income levels a minimum standard binding on the dirty firm has the effect of improving the performance of the cleaner firm a subsidy obtains the same competitive outcome

from streets to suites how the anti biotech movement affected german pharmaceutical firms how do social movements affect decisions within corporations such as the commercialization of new technologies we suggest that the effect of movement activism is conditioned by the internal polity and therefore varies across organizations this article examines how the anti genetic movement in germany during the 1980s affected six domestic pharmaceutical firms commercialization of biotechnology we develop a process model of how movements penetrate the relatively closed polity of private organizations external contestation weakened the position of internal champions of biotechnology precipitated divisions among organizational elites and undermined collective commitment to the technology the movement also increased perceptions of investment uncertainty but the consequences of this uncertainty depended on organizational logics of decision making as a result investments in some firms were tilted away from domestic biotechnology projects the model also explains this variation in organization level outcomes of movement contestation

organizational responses to public and private politics an analysis of climate change activists and u s oil and gas firms we explore how activists public and private politics elicit different organizational responses using data on u s petroleum companies from 1982 to 2010 we investigate how climate change activists serving as witnesses at congressional hearings and engaging in firm protests influenced firms internal and external responses we find that public politics induced internally focused practice adoption whereas private politics induced externally focused framing activities we also find that private and public politics had an interaction effect as firms faced more private political pressure they were less likely to respond to public political pressures similarly as firms faced greater public political pressure they were less likely to respond to private political pressures the results suggest that activists can have a significant impact on firm behavior depending on the mix of private and public political tactics they engage in we discuss the implications of our study for social movement research organ

the economics of credence goods an experiment on the role of liability verifiability reputation and competition credence goods markets are characterized by asymmetric information between sellers and consumers that may give rise to inefficiencies such as under and overtreatment or market breakdown we study in a large experiment with 936 participants the determinants for efficiency in credence goods markets while theory predicts that liability or verifiability yield efficiency we find that liability has a crucial but verifiability at best a minor allowing sellers to build up reputation has little influence as predicted seller competition drives down prices and yields maximal trade but does not lead to higher efficiency as long as liability is violated jel d12 d82

certification under oligopolistic competition in a symmetric duopolistic market where each firm s choice regarding certain quality attributes such as the environmental friendliness of its product is its own private information the extent of horizontal differentiation between firms plays a crucial role in a certifier s optimal certification policy under a non profit certifier it is always the case that both firms produce the highest quality and opt for certification this is also the case under a for profit certifier but only when the degree of horizontal differentiation is sufficiently high when horizontal differentiation is low the for profit certifier by charging a very high certification fee creates maximum vertical differentiation between firms as a result only one firm produces the highest quality and opts for certification whereas the other firm produces the lowest quality and does not opt for certification this asymmetry under a for profit certifier makes the market inefficient which provides one possible explanation for the existence of mostly non profit certifiers in such markets

pareto models top incomes and recent trends in uk income inequality i determine uk income inequality levels and trends by combining inequality estimates from tax return data for the rich and household survey data for the non rich taking advantage of the better coverage of top incomes in tax return data which i demonstrate and creating income variables in the survey data with the same definitions as in the tax data to enhance comparability for top income recipients i estimate inequality and mean income by fitting pareto models to the tax data examining specification issues in depth notably whether to use pareto i or pareto ii generalized pareto models and the choice of income threshold above which the pareto models apply the preferred specification is a pareto ii model with a threshold set at the 99th or 95th percentile depending on year conclusions about aggregate uk inequality trends since the mid 1990s are robust to the way in which tax data are employed the gini coefficient for individual gross income rose by around 7 or 8 between 1996 7 and 2007 8 with most of the increase occurring after 2003 4 the corresponding estimate based wholly on the survey data is around 5

do tournaments have incentive effects much attention has been devoted to studying models of tournaments or situations in which an individual s payment depends only on his or her output or rank relative to that of other competitors academic interest derives from the fact that under certain sets of assumptions tournaments have desirable normative properties because of the incentive structures they provide our paper uses nonexperimental data to test whether tournaments actually elicit effort responses we focus on professional golf tournaments because information on the incentive structure prize distribution and measures of individual output players scores are both available we find strong support for the proposition that the level and structure of prizes in pga tournaments influence players performance

credence goods misleading labels and quality differentiation due to differences in information disclosure mechanisms consumer misinformation about the quality of many credence goods is more endemic at intermediate levels of the quality spectrum rather than at the extremes using an oligopoly model of vertical product differentiation we examine how consumers overestimation of the quality of intermediate quality products affects firms incentives to improve product quality the firms non cooperatively choose the quality of their product before choosing its price or quantity irrespective of the nature of second stage competition bertrand or cournot we find that quality overestimation by consumers increases profit of the intermediate quality firm and motivates it to raise its product s quality in response the high quality firm improves its product quality even further but ends up with lower profit overall average quality of the vertically differentiated product improves which raises consumer surplus social welfare increases when the firms compete in prices but falls when they compete in quantities

equivalence scale relativities and the extent of inequality and poverty most inequality and poverty theory analyzes equivalent income distributions for homogeneous populations incomes are assumed to be deflated by an equivalence scale that accounts for differences in needs between households yet in practice there is no consensus about what the appropriate equivalence scale is the authors analyze how the choice of equivalence scale affects inequality and poverty measures and show that there is a systematic relationship between equivalence scale generosity and the extent of inequality and poverty they consider most of the measures in common use and provide some empirical illustrations copyright 1992 by royal economic society

new ways of looking at old issues inequality and growth abstract the paper uses new cross country data on income and asset land distribution to show that i there is a strong negative relationship between initial inequality in the asset distribution and long term growth ii inequality reduces income growth for the poor but not for the rich and iii available longitudinal data provide little support for the kuznets hypothesis policies that increase aggregate investment and facilitate acquisition of assets by the poor might thus be doubly beneficial for growth and poverty reduction

income distribution and macroeconomics this paper analyzes the role of wealth distribution in macroeconomics through investment in human capital it is shown that in the presence of credit markets imperfections and indivisibilities in investment in human capital the initial distribution of wealth affects aggregate output and investment both in the short and in the long run as there are multiple steady states this paper therefore provides an additional explanation for the persistent differences in per capita output across countries furthermore the paper shows that cross country differences in macroeconomic adjustment to aggregate shocks can be attributed among other factors to differences in wealth and income distribution across countries

the effect of online protests and firm responses on shareholder and consumer evaluation protests that target firms socially irresponsible behavior are increasingly organized via digital media this study uses two methods to investigate the effects that online protests and mitigating firm responses have on shareholders and consumers evaluation the first method is a financial analysis that includes an event study which measures the effect of online protests on the target firm s share price as well as an investigation of the boundary effects of protest characteristics the second method is an online experiment that assesses the effect of an online protest campaign on consumers perception and purchase intention as well as any mitigating effects that a firm s response may have contrary to recent studies suggesting that participation in online protests is only token support without any substantive effects our results show that online protests do hurt firms can expect to suffer financial reputational and sales damage when an online protest campaign mobilizes consumers successfully we also show that online protests are more likely to take firms by surprise than offline protests firms can exacerbate or reduce the damage by their response we find that although firms may repair the damage to consumers purchase intentions the negative effects on a brand s image are harder to rectify the results have valuable implications for protest organizers and managers faced with the task of responding

accounting for inequality trends decomposition analyses for the uk 1971 86 eight explanations for uk income inequality trends between 1971 and 1986 are assessed by pooling evidence from inequality index decompositions by population sub group and by income source the principal causes of the aggregate trends were a mixture of changes in earnings inequality employment structure and unemployment but this mixture changed over time the impact of wage inequality changes on income inequality changes fell during the 1970s and 1980s reflecting the secular decline in the importance of employment earnings for household income packages unemployment changes had their largest impact at the start of the 1980s between 1981 and 1986 self employment income changes appear to have had the largest influence

earnings by size a tale of two distributions part of the conventional wisdom on the subject of the size distribution of earnings is that earnings are approximately lognormal but with an upper tail which is better described by the pareto function 1 the primary purpose of this paper is to re examine these propositions using british new earnings survey data disaggregated by occupational groups we have several reasons for feeling that such a re examination is timely first most previous studies have considered the distribution among all employees while theoretical considerations suggest that disaggregated data might be more appropriate we elaborate this point in section 1 of the paper second the method of estimating the parameters of the pareto and lognormal functions has not always been given the attention it deserves in section 2 we address this issue and also refer briefly to the related one of goodness of fit the remainder of the paper presents parameter estimates for the pareto and lognormal functions using first aggregate data section 3 and then distributions within occupational groups section 4 section 5 compares these two sets of results and at the same time re assesses the conventional wisdom of the superiority of the pareto function in the upper tail section 6 summarizes our findings

the incentive effects of tournaments revisited evidence from the european pga tour this analysis of data from the 1987 european men s professional golf association pga tour strongly supports the hypothesis that the level and structure of prizes in pga tournaments influence players performance specifically players performance appears to vary positively with both the total money prizes awarded in a tournament and the marginal return to effort in the final round of play a value that varies among players largely depending on how the prize money is allocated among finishers of different ranks the authors suggest that these results together with the similar results of their earlier study of the 1984 u s men s pga tour may have implications for the design of compensation systems for certain groups of workers such as corporate executives college professors and salespeople

signaling corporate social responsibility third party certification versus brands corporate social responsibility csr is a credence attribute of products which can be signaled either through a label certified by a third party or via unsubstantiated claims used as part of a brand building strategy we use an experimental posted offer market with sellers and buyers to compare the impact of these signaling strategies on market efficiency only third party certification gives rise to a separating equilibrium and an increase in csr investments unsubstantiated claims can generate a halo effect on consumers whereby the latter are nudged into paying more for the same level of csr investments by firms

measuring inequality change in an economy with income growth abstract this paper reassesses an article by fields which criticizes using standard income inequality indices for the evaluation of high income sector enlargement growth this paper dissents in three ways the intuition that motivated fields paper is found to only partially account for the changes occurring during growth the inequality index that fields developed is shown to incorporate the concept of symmetry and the concept of inequality as the expected experience of income differences is shown to support the use of the standard indices

education economic growth and measured income inequality in this paper education simultaneously affects growth and income inequality more education does not necessarily decrease inequality when the latter is assessed by the lorenz dominance criterion increases in education first increase and then decrease growth as well as income inequality when measured by the gini coefficient there is no clear functional relationship between growth and measured income inequality the model identifies regimes of this relationship which depend crucially on the production and schooling technology conventional growth regressions with human capital and inequality as regressors may miss the richness of the underlying nonlinearities but viewed as approximations may still provide important information on the nonlinear relationship between growth and education

certification of corporate social responsibility activities in oligopolistic markets we investigate the impact of alternative certifying institutions on firms incentives to engage in costly corporate social responsibility csr activities as well as their relative market and societal implications we find that the csr certification standard is the lowest under for profit private certifiers and the highest under a non governmental organization ngo with the standard of a welfare maximizing public certifier lying in between yet regarding industry output this ranking is reversed certification of csr activities is welfare enhancing for consumers and firms and should be encouraged finally the market and societal outcomes o f csr certification depend crucially on whether certification takes place before or after firms csr activities

change actors in the u s electric energy system the role of environmental groups in utility adoption and diffusion of wind power we study the contribution of environmental groups to new technology adoption and diffusion by dominant incumbents building on institutional and social movement theory we develop a theoretical framework that sheds light on environmental groups as change actors we theorize that by approaching embedded key constituents with various strategic actions environmental groups affect taken for granted beliefs build legitimacy for renewable energy technologies and convince skeptical constituents to support the new technology we verify our theoretical framework with a case study of wind power development in colorado we find that environmentalists educate constituents on the benefits of the new technology engage in activities leading to regulatory and legislative decisions for wind while also providing direct assistance to the utility as a result utilities are both pressured and encouraged to adopt and diffuse wind power on a large scale this research directs attention to the role of environmental groups as change actors and the legitimating effects of their actions it highlights their part in creating a more favorable institutional environment for new technologies while directly influencing the incumbent s technology choice this paper contributes to an understanding of bottom up actor initiated changes in energy systems taking into account both the systemic technological infrastructure and the institutional context

income inequality education expenditures and growth abstract recent studies have reported a negative association between income inequality and economic growth if true what accounts for this finding what are possible transition mechanisms that might link the two this paper explores one such mechanism income inequality raises expenditures for public education as a fraction of gross domestic product gdp although public education expenditures are positively associated with future economic growth the contemporaneous effect upon growth is negative given this cost upon current growth these findings may help to explain the lack of a large positive effect from the growth of human capital upon economic growth as reported in the literature

measures of distributional change an axiomatic approach in recent years a number of interesting papers have appeared in the general field of the analysis of changes in a frequency distribution the most common applications of such analysis are in the areas of income and wealth re distribution and the contributions have usually focussed on a particular specialised issue such as mobility of individuals within a structure or of horizontal inequity as opposed to vertical inequality implicit in the comparison of two distributions a number of approaches to each of these problems have been suggested and indeed several specific practical indices of mobility or inequity have been proposed 1 whilst some of these can be shown to have very useful features in their application it is probably fair to say that most derive from an ad hoc approach to the particular aspect of the problem on which the author had focussed it is interesting to note that comparatively few papers attempt to exploit the similarities involved in each of these issues all this contrasts rather sharply with the state of play in an obviously closely related game that of the measurement of inequality much of the essential foundation of the problem of measuring inequality as we presently understand it seems to be more or less sorted out in a systematic fashion roughly speaking what may be done is as follows given

a new data set measuring income inequality this article presents a new data set on inequality in the distribution of income the authors explain the criteria they applied in selecting data on gini coefficients and on individual quintile groups income shares comparison of the new data set with existing compilations reveals that the data assembled here represent an improvement in quality and a significant expansion in coverage although differences in the definition of the underlying data might still affect inter temporal and international comparability based on this new data set the authors do not find a systematic link between growth and changes in aggregate inequality they do find a strong positive relationship between growth and reduction of poverty

ecolabeling consumers preferences and taxation abstract ecolabeling is a means of reducing the information gap between consumers and producers we study the implication of ecolabeling a supposedly green good for a consumer s allocation of income between a dirty and the supposedly green good in the model the role of the ecolabel is to help product differentiation to give reliable information and to reduce informational asymmetries we show that a conscious consumer someone with a stronger green attitude or quality concerns demands more ecolabeled goods price oriented consumers demand fewer ecolabeled goods a subsidy resp tax on the price of the ecolabeled resp dirty good leads to a larger consumption of the ecolabeled resp dirty good whereas it may increase or decrease the demand for the dirty resp ecolabeled good depending on whether the consumer views both goods as gross substitutes or complements we then use a cross individual dataset of 22 568 consumers and show that the demand for ecolabeled goods increases strongly with the consciousness of the consumer but decreases for price oriented consumers ecolabel oriented consumers feel more informed more conscious consumers prefer a subsidy on green goods and a tax on dirty goods price oriented consumers do not care about the green subsidy but would vote against a tax on the dirty goods

the economics of movement success business responses to civil rights mobilization1 this article explores why movements are successful in obtaining concessions from economic actors while social movement theorists have suggested that economic actors weigh the costliness of protests the author considers the vulnerability of movement targets to both the cost of disruptions in routine transactions and the cost of conceding to movement demands by addressing the magnitude of these costs and their interaction the author derives an economic opportunity structure to predict the receptivity of economic actors to movement demands and the likely struggles among them over the decision to yield also this cost assessment approach reveals patterns of vulnerability across economic sectors to the costs of disruptive mobilization the author tests this analysis based on case studies of the responses of economic actors to civil rights mobilization in the 1960s in five southern localities these cases depict how the character of protest and variation in the configuration of business communities defined

the effect on income distribution of development the growth rate and economic strategy abstract an analysis of cross section and time series data for 83 countries confirms some and contradicts other work on income distribution new findings include a dualistic socio political system is highly unfavorable for equality neither the extent of government intervention in the economy nor the rate of manufactured exports are systematically related to income distribution the analysis confirms that there is no systematic relationship between equality and the rate of economic growth educational participation and a reduction in the share of primary exports in gdp are both favorable for equality there is some support for the kuznets hypothesis that inequality increases as per capita income rises to about 400 and then declines with further income increase but the empirical support is not strong and may be weakening over time these findings lead to more optimistic conclusions then other work that rapid growth in a mixed economy is quite consistent with unchanged or even improved income distribution even at early stages of development

eco labelling scheme environmental protection and protectionism in this paper a model of international duopoly is developed involving competition in both prices and levels of environmental friendliness and the implications of government policies are studied it is shown that contrary to the conventional wisdom a regulatory increase in the minimum required level of environmental friendliness of imported goods may harm the home firm and may result in a rise in the volume of imported goods whether consumers lose or gain from such a regulatory increase depends on consumption spillover effects we also show that under certain conditions the duopoly s equilibrium choice of levels of environmental friendliness is socially optimal jel classification f00 eco etiquetage protection environnementale et protectionnisme ce memoire developpe un modele de duopole international ou la concurrence se fait a la fois par les prix et par les niveaux de sensibilite aux problemes environnementaux on etudie les impacts des politiques gouvernementales contrairement a ce que suggere la sagesse conventionnelle il semble qu un accroissement reglementaire dans le minimum requis de disposition favorable a l environnement des biens importes peut nuire a l entreprise locale et peut resulter en un accroissement du volume de biens importes le consommateur perdra ou gagnera en consequence de cette accroissement de la reglementation selon la nature des effets de retombees on montre aussi que sous certaines conditions le choix des niveaux d equilibre de sensibilite aux problemes de l environnement s avere socialement optimal

development and distribution a critique of the cross country u hypothesis abstract this paper questions the validity of a modern paradigm viz the u hypothesis it argues that notwithstanding contrary claims the recent cross country econometric studies by ahluwalia and others have little in common from a methodological point of view with kuznets earlier intertemporal national studies ahluwalia s cross country u curve is found to be based on defective statistics and questionable methodological premises in specific the estimation of one u curve from observations on both ldcs and dcs is criticised a sample restricted to the ldc group considerably weakens support for the u hypothesis further even marginal variations in the data set lead to the virtual disappearance of ahluwalia s empirical relationship the paper concludes that the cross country u hypothesis is more of a hindrance than an aid to our comprehension of the relationship between economic growth and income distribution

credence goods efficient labelling policies and regulatory enforcement we analyse the optimality of information revelation of hidden attributes of credence goods via alternative labelling procedures when consumers are heterogeneous in their willingness to pay for the hidden attribute producers can either self label their products or have them certified by a third party the government can impose self or third party labelling requirements on either the green or the brown producers our benchmark model develops a condition that links the optimal imposition of third party labelling to the relative market share of each type of the good under complete information we extend our analysis to incorporate asymmetric information and cheating by the producers when corrupt producers can affix spurious labels the government needs to supplement the labelling policy with costly monitoring activities we find that mandatory self labelling schemes generally dominate mandatory third party labelling unless the market share effect greatly exceeds the incentive to cheat effect

does the baseball labor market contradict the human capital model of investment this paper examines whether experienced players in major league baseball are paid more than their contribution to team revenue the author shows that wages increase with experience independently of productivity gains the results therefore contradict the human capital model of investment the evidence is in fact consistent with implicit contract models because most older players are relatively overpaid copyright 1992 by mit press

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

measuring social tension from income class segregation we develop an index that effectively measures the level of social tension generated by income class segregation we adopt the basic concepts of between group difference or alienation and within group similarity or identification from the income bi polarization literature but we allow for asymmetric degrees of between group antagonism in the alienation function and construct a more effective identification function using both the relative degree of within group clustering and the group size to facilitate statistical inference we derive the asymptotic distribution of the proposed measure using results from u statistics as the new measure is general enough to include existing income polarization indices as well as the gini index as special cases the asymptotic result can be readily applied to these popular indices evidence from the panel study of income dynamics data suggests that while the level of social tension shows an upward trend over the sample period of 1981 to 2005 government s taxes a

the economics of eco labeling standards costs and prices abstract the existing eco label landscape is fragmented because of the presence of numerous labels with different standards and is a pre competitive environment for firms to play in with many unanswered questions different standards eco labels are built around have different effects on credibility and legitimacy costs and benefits and ability to achieve sustainability goals of eco labeling focusing on eco label standards and using a hotelling type horizontal differentiation model we identify standards specific issues for and characterize primary barriers to eco labeling some of the major findings are as follows 1 more rigorous environmental standards enforced by higher integrity labels do not necessarily translate into higher selling prices 2 higher prices commanded by labeled products do not guarantee that a firm will derive higher profits from eco labeling 3 auditing fees paid per product unit being inspected for ensuring compliance with an eco label standard rather than participation fees paid up front is the primary de facto barrier to business involvement in eco labeling and 4 customers willingness to pay price premiums for eco labeled products is not a sufficient condition to generate a premium in the market

determining the impact of federal antidiscrimination policy on the economic status of blacks a study of south carolina this paper evaluates alternative explanations for the dramatic increase in black employment in south carolina manufacturing that occurred in the mid 1960s black progress in traditionally segregated sectors of manufacturing in operation at the time jim crow laws were passed cannot be attributed to tight labor markets the decline of agriculture or the growth of education of the black workforce the only plausible explanation is federal government civil rights and affirmative action policy for newer industries that entered the state on a large scale after world war ii the growth of skills among blacks accounts for black economic progress copyright 1989 by american economic association

inequality with ordinal data the standard theory of inequality measurement assumes that the equalisand is a cardinal quantity with known cardinalization however one often needs to make inequality comparisons where either the cardinalization is unknown or the underlying data are categorical we propose an alternative approach to inequality analysis that is rigorous has a natural interpretation and embeds both the ordinal data problem and the well known cardinal data problem we show how the approach can be applied to the inequality of happiness and of health status

bargaining power strike durations and wage outcomes an analysis of strikes in the 1880s strike outcomes in the 1880s had a winner take all character successful strikes ended with a discrete wage gain failed strikes ended with a return to work at the prestrike wage we present a theoretical interpretation of these outcomes based on a war of attrition model we fit an empirical model specifying the capitulation times of the two parties and the size of the wage gain in the event of a strike success the results show a systematic relation between the determinants of strike success and the determinants of the wage gain for a successful strike

income inequality among female heads of households racial inequality reconsidered this paper investigates the factors that might have influenced earnings inequality among female heads of households over an extended period the study used the generalized entropy measures of inequality in short run as well as long run income for the period 1978 86 the results suggest that short run inequality has generally increased these fluctuations are due partially to the existence of transitory components which distort our view the measured long run inequality shows a decline in the early years because of the smoothing of the transitory components race in conjunction with age education and marital status is used to investigate their effects race and education are shown to be the most influential factors the mobility profiles show the existence of permanent inequality among female heads of households

testing the determinants of income distribution in major league baseball i introduction income of professional athletes is a frequent topic of discussion of fans sportscasters and the general public economists have also increasingly been attracted to this topic because the distribution of income of these players has both policy and business implications as a consequence the report of major league baseball s mlb blue ribbon panel formed in 1998 by mlb commissioner bud selig received quite a lot of attention this panel was charged with describing and explaining the economic condition of mlb comprised of such dignitaries as former federal reserve chairman paul volker senator george mitchell yale university president richard levin and columnist george will this panel reported that team payrolls have become increasingly disparate the gap between rich and poor teams is not only wide but is growing levin et al 2000 a case in point is the fact that the salary of the highest paid player in the 2000 season los angeles kevin brown at 15 7 million was 95 of the entire payroll of the poorest team the minnesota twins the effect according to the panel s report is a dramatic decline in parity and competitiveness of mlb since 1994 a team in the top payroll quartile has won every world series game in 1999 the teams with the five largest payrolls had an average winning percentage of 0 557 whereas the five poorest teams had a comparable figure of 0 444 the report discusses various recommendations that may narrow this gap leading to what one might call convergence in team payrolls this article examines the distribution of income in mlb for 1985 to 2000 we revive and extend a technique first suggested by thurow 1970 and show how it can be used to test for time trends versus cross sectional demographic and economic aspects influencing income distribution thurow 1970 discusses the impact of various measures on median income in the present case by calculating the gini coefficient we can discuss the impact that the explanatory variables have on income inequality in the context of mlb we attempt to shed light on the reasons why teams have greater or lesser payroll disparity we leave the question of the effect of between team payroll inequality on team wins and team revenues for future research the issue of whether to use an inequality measure that is based on a particular distribution or one that is distribution free has been widely discussed in the income distribution literature silber 1999 ryu and slottje 1999 in advocating the use of parametric distributions point to several benefits of estimating the lorenz curve in this manner these benefits include the ability to summarize thousands of observation points with a few parameters the ability to estimate the density function at any point an enhanced ability to construct inequality measures and the ability to formulate possible laws that would otherwise not be possible to detect however there are problems associated with the use of a parametric lorenz curve such as the choice of a suitable distribution the problem is compounded by the fact that income data are often grouped and have an open ended highest income category making it difficult to obtain accurate estimates one advantage of using professional sports data is the fact that the salary is available per individual and is not grouped consequently an actual number is available for the highest income this study analyzes payroll inequality in a professional sport by team that is for each year we calculate a measure of inequality for each mlb team and consider the characteristic differences in within team payroll distributions our study is not however the first to consider income inequality within professional team sports depken 2000 and jewell and molina 2004 find that mlb teams with greater wage disparity have fewer wins furthermore sommers 1998 finds a negative relationship between team success and within team payroll inequality using national hockey league data

on the economics of labels how their introduction affects the functioning of markets and the welfare of all participants are labels good or bad for consumers and firms the answer may seem straightforward since labels improve information yet economic theory reveals situations where their introduction reduces the welfare of at least some market participants this essay reviews the theoretical literature on labels in order to identify and explain the main reasons that may cause labeling to produce undesirable side effects in contrast to earlier reviews that either concentrate on narrow topics or treat the subject in a more or less informal way we bring together the main results from all the relevant topics by presenting and discussing the assumptions and model building techniques that underpin them the advantage of this approach is that it identifies the origin of the differences between results thus allowing the synthesis of results that sometimes appear even to be contradictory we focus on quality labels and examine the impact of labeling on market structure the side effects of costly certification issues related to the label s trustworthiness the rationale for mandatory vs voluntary labeling the level at which the label s standard is set according to the agency that selects it the political economy of labels that is pro or anti label lobbying lobbying to affect the label s standard and lobbying in favor or against the label s mandatory imposition these topics cover a wide range of applications including genetically modified organism gmos organic produce geographic indicators controlled origin eco labels etc we conclude by identifying topics that require further research

the evolution of the scientific productivity of highly productive economists this paper studies the evolution of research productivity of a sample of economists working in the best 81 departments in the world in 2007 the main novelty is that in so far as a productivity distribution can be identified with an income distribution we measure productivity mobility in a dynamic context using an indicator inspired in an income mobility index suggested by fields 2010 for a two period world productivity is measured in terms of publications weighted by the citation impact of the journals where each article is published in the periodical literature we study the evolution of average productivity productivity inequality the extent of rank reversals and productivity mobility for seven cohorts as well as the population as a whole we offer new evidence confirming previous results about the heterogeneity of the evolution of productivity for top and other researchers however the major result is that contrary to what was expected for our sample of very highly productive scholars the effect of rank reversals between the two periods on overall productivity mobility offsets the effect of an increase in productivity inequality from the first to the second period in the youngest five out of seven cohorts jel a11 a12 b41 d63 i32

financing higher education and majority voting abstract this paper examines the state funding of higher education treated as an investment good generating an externality under majority voting the model considers a single cohort over two periods individuals maximise net lifetime income subject to the government s budget constraint with a proportional tax cyclical voting does not occur despite double peaked preferences comparative static results are obtained a fall in non education expenditure leads to a fall in the choice of grant and a positive externality is a necessary though not sufficient condition for ensuring majority support for some positive level of the grant

income inequality human capital accumulation and economic performance we show that greater income equality implies higher human capital accumulation and economic performance in an overlapping generations model with heterogeneity in income and talent given liquidity constraints and declining marginal utility individuals with a given level of talent receive education if their initial income is higher than a threshold level and the threshold is lower for more talented individuals assuming the more talented create more human capital when educated greater initial income equality for one generation then imply not only higher aggregate human capital accumulated by that generation but an improvement in all subsequent generations initial income distributions

eco labeling and market equilibria with noisy certification tests an intriguing alternative to traditional methods for regulating externalities is the provision of information about firms environmental attributes an increasingly important example of this approach is eco labeling where a third party certifies firms products such schemes are currently used in a variety of countries this paper investigates the equilibria that may occur with eco labeling and the attendant welfare effects i model certification as a noisy test subject to both type i and type ii errors but where green firms more likely to pass than brown firms while it commonly leads to an increase in the fraction of green units in the market the introduction of an eco label can either increase or decrease welfare

regulating externalities through testing abstract testing for compliance with regulation of a negative externality is analyzed in a strategic framework the outcome is described where the number tested and the penalties for observed noncompliance are each controlled by different agencies or by different levels within the regulatory agency and where the number tested cannot be precommitted comparative statics results are provided and the equilibrium is compared with the welfare optimum for different objectives of those doing the testing it is shown that the actual enforcement decision can sometimes be optimally delegated even if those doing the enforcement have objectives different from minimizing expected social cost

immigration and socioeconomic gaps theory and applications during the first decade of israel s existence large waves of immigrants came from europe and the middle east this paper introduces an empirical study which compares the occupational socioeconomic score differentials between ethnic groups within and outside the kibbutz the three groups examined are from asia and africa from europe and america and the native born population it is found that the occupational socioeconomic score differentials after migration are lower in the kibbutz than outside it and that socioeconomic gaps outside the kibbutz increase after migration in this paper a model is presented which explains the empirical results it compares the effects of migration inside the kibbutz organized as a labour managed firm with the effects of migration inside the city assumed to be organized as a perfectly competitive firm the model also develops a gap function that quantifies the socioeconomic gaps and uses iso gap curves to compare the premigration and postmigration gaps

measuring inequality change in an economy with income growth abstract this paper analyzes how to measure changes in inequality in an economy with income growth the discussion distinguishes three stylized kinds of economic growth 1 1 high income sector enrichment 2 2 low income sector enrichment 3 3 high income sector enlargement in which the high income sector expands and absorbs persons from the low income sector th e two enrichment types pose no problem for assessing inequality change in the course of economic growth for high income sector enrichment growth inequality might reasonably be said to increase whereas for low income sector enrichment inequality might be said to decrease these adjustments are non controversial and non problematical where problems arise is in the case of high income sector enlargement growth in that case the two alternative approaches have been shown in this paper to yield markedly results 1 1 the traditional inequality indices generate an inverted u pattern of inequality that is inequality rises in the early stages of high income sector enlargement growth and falls thereafter 2 2 the new approach suggested here based on axioms of gap inequality and numerical inequality generates a u pattern of inequality that is inequality falls in the early stages of high income sector enlargement growth and rises thereafter the discrepancy between the familiar indices and the alternative approach based on axioms of gap inequality and numerical inequality bears further scrutiny two courses of action are possible one might try to axiomatize inequality in ways that generate an inverted u pattern in high income sector enlargement growth thereby rationalizing the continued use of the usual inequality indices with the inverted u property alternatively one might retain the axioms proposed here embed them into a more formal structure and construct a family of inequality indices consistent with them others might wish to pursue the first course i am at work on the second

subsidies for higher education who should pay the resource costs of higher education this paper investigates a simple model of the general equilibrium of the labor market with three skill levels those in the population with the lower level of intelligence and or sophistication can only become low skilled workers but the brighter segment of the population can become either high or medium skilled workers given the tax structure the welfare of each group is maximized by a unique subsidy rate on the cost of training high skilled workers under several circumstances the lower iq group wants a higher subsidy rate than will the group that benefits directly from the training

private vs public regulation political economy of the international environment minimum standards set by a world environmental organization weo and ngo labelling are promoted as alternative approaches to international environmental protection we explore the potential inter play between these two approaches when the weo is subject to pressure from producers we find that if weo and ngo schemes are mutually exclusive then the existence of an ngo alternative increases industry resistance to weo proposals and this may reduce welfare if however the schemes are run in parallel existence of the ngo lessens producer opposition to weo activities this allows the weo to be bolder in its proposals which is good for welfare

when do people exploit moral wiggle room an experimental analysis of information avoidance in a market setup abstract we investigate if decision makers avoid information to exploit moral wiggle room in green market settings we therefore implement a laboratory experiment in which subjects purchase products associated with externalities in six between subjects treatments we alter the availability of information on the externalities the price of revealing information as well as the nature of the externality which could either affect another subject or change the amount spent by the experimenters on carbon offsets we find that subjects do not strategically avoid information when revealing information is costless when a very small cost of revealing information is introduced their behavior depends on the relation between prices and externalities in situations in which it is relatively cheap to have a large impact on the recipient s payoff subjects avoid information in order to choose selfishly for other parameterizations subjects behave either honestly egoistically or altruistically

inequality measurement an axiomatic approach the theory of inequality measurement is examined using some basic axioms which extend the pigou dalton principle of transfers from these basic axioms various inequality indices may be derived as an alternative to ad hoc methods or to methods involving prior specification of a social welfare function the key idea is the concept of distance between two income shares conventional inequality indices are analysed in terms of their implied distance functions

are fair trade goods credence goods a new proposal with french illustrations in the literature fair trade ft goods are usually associated with other products differentiated by process attributes such as organic food genetically modified gm food or child labour free clothing all of these products are regarded as credence goods this classification refers to the simplified definition of credence goods which describes product attributes which consumers cannot evaluate even after having consumed the good focusing on the characteristics of ft goods this article proposes a reassessment of the link between ft goods and credence properties as defined by darby and karni we first demonstrate that 1 the usual classification masks important particularities of ft goods compared to other goods with process attributes and 2 the full definition of credence goods may even provide a better description of the quality of ft goods however and this is our second theoretical contribution the lack of consensus among experts concerning ft standards and their level of efficiency encourage us to consider ft goods as indeterminate goods as defined by lupton this result leads us to suggest a new typology of product attributes summarized in an innovative diagram it sheds light on how competition between the different ft approaches works and why the ft market is still confined to a niche if not threatened with collapse we mainly illustrate our theoretical analysis with observations relating to the french ft market and institutions

factor shares and savings in endogenous growth in models of steady investment driven growth an individual s propensity to save depends on how much of his income is drawn from accumulated factors of production capital rather than from nonaccumulated factors when agents are heterogeneous in this respect growth oriented policies have distributional consequences and in the absence of lump sum redistribution their implementation faces political constraints if the median voter is capital poor relative to the economy s representative agent political interactions tend to slow down growth when policy acts on capital s income share and tend to accelerate it when investment subsidies are the policy instrument of choice copyright 1993 by american economic association

distributive politics and economic growth a crude distinction between economics and politics would be that economics is concerned with expanding the pie while politics is about distributing it in this paper we analyze the relationship between the two we focus on how an economy s initial configuration of resources shapes the political struggle for income and wealth distribution and how that in turn affects long run growth our main conclusion is that inequality is conducive to the adoption of growth retarding policies we derive this result from a simple political economy model of growth and present cross country evidence consistent with it the key feature of our model is that individuals differ in their relative factor endowments we distinguish between two types of factors an accumulated factor called capital and a nonaccumulated factor called labor growth is driven by the expansion of the capital stock which is in turn determined by individual saving decisions long run growth is endogenous as the aggregate production function is taken to be linearly homogeneous in capital and productive government services taken together the provision of government services is financed by a tax on capital because government services are productive a small tax on

voluntary eco labeling and the price premium international environmental organizations propose voluntary eco labeling as a market incentive to promote industry to operate in an ecologically sustainable and environmentally friendly manner a microeconomic analysis questions whether voluntary eco labeling will cause producer profits in a competitive industry to decline and whether eco labeling will necessarily generate different prices for labeled and unlabeled product using wood product as an example results identify conditions that may exist when firms lose profits even under a voluntary system and where existing production constraints may lead to a single price regardless of labeling

raised without antibiotics lessons from voluntary labeling of antibiotic use practices in the broiler industry voluntary labeling improves market efficiency if consumers receive the product characteristics they demand and producers are compensated for producing these characteristics for this to occur label claims have to be truthful credible and understandable we examine the introduction of raised without antibiotics rwa label claims in the broiler industry by perdue farms perdue and tyson foods tyson in 2007 and the events that follow we ask whether voluntary label claims were able to improve efficiency in the market for rwa chicken products in this case evidence presented as part of court testimony suggests that tyson did not deliver the rwa attribute that consumers demanded competitors suffered and tyson profited from introducing what was ruled to be a false and misleading label claim to the marketplace while the media informed consumers and stockholders of these events we found little evidence in publicly available data literature or documentation from court cases that tyson suffered significant harm in the market or from stockholders the u s department of agriculture food safety and inspection service did ultimately remove tyson s label claims from the marketplace and the legal system provided some redress to competitors and consumers even so labels with animal raising claims such as rwa and voluntary process based label claims in general continue to be challenged by similar issues that is consumer confusion the absence of universally accepted definitions and varying degrees of credibility

explaining international and intertemporal variations in income inequality this paper explores the propositions that income inequality is relatively stable within countries and that it varies significantly among countries a new and expanded data set provides broad support for both propositions drawing on a political economy and capital market imperfection arguments to explain the intertemporal and international variation in inequality the empirical analysis shows that the predicted variables associated with the first argument a measure of civil liberties and the initial level of secondary schooling and the second argument a measure of financial depth and the initial distribution of land are indeed important determinants of inequality this paper explores two propositions regarding income inequality they are first income inequality is relatively stable within countries and second it varies significantly across countries to illustrate note that the gini coefficient in india remained almost constant for forty years 1951 92 with mean 32 6 and standard deviation 2 0 2 in contrast the variation in gini coefficients across countries is large 61 9 in honduras in 1968 compared with 17 8 in bulgaria in 1976 if substantiated these propositions have potentially significant implications for poverty the significance of the first is obvious barring any fundamental socio political change poverty reduction will depend crucially on the rate of economic growth given this the significance of the second is that in inegalitarian economies the poor will enjoy a smaller share of any national increment in income than in more egalitarian ones drawing on a new and expanded data set on inequality deininger and squire 1996a the first of the paper s three sections conducts standard statistical tests of the two propositions the sample comprises 573 observations on the most common measure of inequality the gini coefficient for 49 developed and developing countries covering the period 1947 94 the results broadly confirm our two propositions specifically analysis of variance anova shows that about 90 of the total variance in the gini coefficients

eco labels trade and protectionism eco labels are suspected to serve protectionist purposes we analyze the choice between an environmental standard and a voluntary eco label scheme in a partial trade model with one domestic firm and one foreign firm the environmental standard will only apply to the domestic firm while both firms can adopt the eco label pollution is production related and domestic consumers demand products that are produced in an environmentally friendly way our results show that it may be optimal for the domestic government to introduce an eco label and get both firms to adopt the label instead of setting an environmental standard however to what extent this policy serves protectionist purposes is ambiguous in particular if the willingness to pay for green products is sufficient to cover the pollution abatement costs of the foreign firm foreign firm profit will increase while domestic firm profit will decrease compared to the outcome with a domestic environmental standard on the other hand if the willingness to pay for green products is insufficient the foreign firm would be better off with a domestic environmental standard
