the environmental kuznets curve ekc and the environmental problem of the day this study evaluates the relevancy of the environment kuznets curve ekc hypothesis to the environment problem of the world to achieve this objective different aspects of the ekc have been critically reviewed the study concludes that ekc growth strategy grow now clean later is too much resource intensive and has huge environmental cost that this planet may not be able to absorb in future the key recommendations of the study are that developing countries should follow different growth path than that of the ekc the growth path that must be sustainable and less destructive since energy is the most important determinant of the pollution therefore the governments should frame a special policy for renewable energy by taxing the fossil and subsidizing the renewables

empathy or antipathy the impact of diversity mixing across ethnic and class lines could potentially either spur understanding or inflame tensions between groups we find that white students at a large state university who were randomly assigned african american roommates in their first year are more likely to endorse affirmative action policies several years later whites who were randomly assigned black roommates are also more likely to say they have more personal contact with and interact more comfortably with members of minority groups whites who were assigned either black or low income roommates are more likely to view a diverse student body as essential for a high quality education students become less supportive of higher taxes for the wealthy when assigned roommates from high income families and they appear more likely to volunteer when assigned roommates from low income families taken together these results suggest that students become more empathetic with the social groups to which their roommates belong

investigating environmental kuznets curve from an energy intensity perspective empirical evidence from china abstract this study pioneers investigating the environmental kuznets curve ekc hypothesis and its possible regional differential characteristics in china based on 2003 2017 years of provincial panel data this research employs panel smooth transition auto regression pstr model to analyze the impact of income levels on environmental pollution and identify the ekc threshold of energy intensity then 30 chinese provinces were categorized by energy intensity to examine the inter provincial and interregional differences in the ekc threshold of energy intensity rather than the traditional threshold of income the results indicate that china s pollution emissions and energy intensities show a stepwise decreasing pattern from the western region to the eastern region in addition the impact of income levels on pollution emissions is non linear and the critical value of energy intensity is 0 9168 between the high and low regimes an inverted u shaped environmental kuznets curve is accepted for energy intensity with 0 7670 as its threshold value when the energy intensity is higher lower than the threshold value the income elasticity of pollution emission is positive negative the more developed provinces and municipalities mainly in the eastern region are proved to exceed the threshold than the provinces in the central and western regions within the sample period given these findings this study further divides china s provinces into eco friendly low pollution and high pollution provinces and accordingly the most important policy recommendations were discussed for policy makers and researchers this research can provide a new insight to investigate countries with unbalanced development levels within and a reference for environmental governance policies in sub regions

economic growth and pollutant emissions in tunisia an empirical analysis of the environmental kuznets curve abstract this paper investigates the relationship between economic growth and pollutant emissions for a small and open developing country tunisia during the period 1961 2004 the investigation is made on the basis of the environmental kuznets curve hypothesis using time series data and cointegration analysis carbon dioxide co 2 and sulfur dioxide so 2 are used as the environmental indicators and gdp as the economic indicator our results show that there is a long run cointegrating relationship between the per capita emissions of two pollutants and the per capita gdp an inverted u relationship between so 2 emissions and gdp has been found with income turning point approximately equals to 1200 constant 2000 prices or to 3700 in ppp constant 2000 prices however a monotonically increasing relationship with gdp is found more appropriate for co 2 emissions furthermore the causality results show that the relationship between income and pollution in tunisia is one of unidirectional causality with income causing environmental changes and not vice versa both in the short run and long run this implies that an emission reduction policies and more investment in pollution abatement expense will not hurt economic growth it could be a feasible policy tool for tunisia to achieve its sustainable growth in the long run

exposure to female colleagues breaks the glass ceiling evidence from a combined vignette and field experiment abstract we study discrimination among recruits in the norwegian armed forces during boot camp in a vignette experiment female candidates are perceived as less suited to be squad leaders than their identical male counterparts adding positive information leads to higher evaluations of the candidates but does not reduce the amount of discrimination however randomized intense collaborative exposure to female colleagues reduces discriminatory attitudes male soldiers who were randomly assigned to share room and work in a squad with female soldiers during the recruit period do not discriminate in the vignette experiment

the role of brand image and product characteristics on firms entry and oem decisions we investigate the optimal market entry and original equipment manufacturer oem decisions of a firm facing a market in which firms brands can be horizontally differentiated and products can be vertically differentiated the entrant might sell under its own brand and compete with an incumbent become a supplier to the incumbent or both findings reveal that when consumers perceive the firms are horizontally and vertically differentiated the entrant profits by simultaneously entering the market and establishing an oem arrangement with the incumbent in such competitive scenarios both buyer and seller increase profits by agreeing on wholesale prices that are not too low which softens both horizontal and vertical conflict between the firms findings also show that the incumbent may prefer to pay high wholesale prices to the entrant even if the incumbent had the option to source the product independently at a lower marginal cost when firms have the capability of producing each other s product lines su

are ghettos good or bad spatial separation of racial and ethnic groups may theoretically have positive or negative effects on the economic performance of those groups we examine the effects of segregation on outcomes for blacks in schooling employment and single parenthood we find that blacks in more segregated areas have significantly worse outcomes than blacks in less segregated areas we control for the endogeneity of location choice using instruments based on political factors topographical features and residence before adulthood a one standard deviation decrease in segregation would eliminate one third of the black white differences in most of our outcomes

cultural leader and the dynamics of assimilation abstract this paper studies the population dynamics of cultural traits in a model of intergenerational cultural transmission with a perfectly forward looking cultural leader we show that there exists a threshold size in terms of population above which the cultural leader becomes active we also show that a policy affecting some key parameters such as the cost of providing the religious good has a different impact in the short run and in the long run due to over reactions or under reactions of the different cultural groups finally we study the cultural competition between two forward looking cultural leaders with opposite objectives we show that the steady state cultural equilibrium depends on the time preference structure of the two leaders

implicit understandings in channels of distribution formal agreements can be used to achieve coordination among channel members these agreements work by exerting explicit control over the members who make the agreements however implicit understandings can be used as a partial substitute for more formal agreements in this paper we show that implicit understandings can develop as channel members learn about each other s behavior we show that this learning leads to the use of the implicit influence each channel member has over the other s behavior the learning leading to an implicit understanding requires some form of experimentation or historical observation this learning results in an oscillating retail price when only one channel member learns the other s behavior both channel members obtain greater profits than when neither member learns and both channel members obtain less profits than when both members learn however the member who does not learn obtains more profits than the member who learns we also show that implicit understandings r

manufacturers channel structures when selling asymmetric competing products abstract manufacturers often face the fundamental channel structure decision namely whether to sell their products directly to consumers or indirectly through an intermediary to address this issue extensive research has analyzed equilibrium channel structures for competing equally substitutable products however in reality many competing products are asymmetric in both substitutability and brand equity in this paper we study how these two asymmetric characteristics affect the equilibrium channel structures of manufacturers selling competing products following some recent studies we adopt a refined consumer demand model derived from the representative consumer utility function based on this model we examine three possible types of competition between the two supply chains cournot quantity competition bertrand price competition and bertrand cournot competition we find that brand equity substitutability as well as the type of competition all play important roles in determining the equilibrium channel structures specifically in equilibrium a manufacturer always sells directly when its rival competes on quantity moreover when there is sufficient asymmetry in either brand equity or substitutability manufacturers tend to sell directly our results demonstrate that the benefits of selling indirectly shown in previous studies depend critically on the assumptions of equally substitutable products and bertrand competition

the ekc for so2 does firm size matter abstract the environmental kuznets curve hypothesis ekc predicts an inverse u shaped relationship between environmental pollution and per capita income the literature with respect to the ekc is vast but far from conclusive this paper adds firm size to the standard ekc reduced form regression and analyses whether firm size matters once income and composition are controlled for results suggest that large firm countries are initially associated with higher levels of environmental damage however as economies develop large firm countries find it easier to adopt more stringent environmental legislation once environmental damage starts to decrease the decrease is much larger in large firm countries

sulfur dioxide so2 emissions and government spending on environmental protection in china evidence from spatial econometric analysis abstract this study pays attention to a rarely discussed but important issue regarding the influence of the government s environmental protection expenditure on sulfur dioxide so2 emissions in china under consideration of the potentially spatial dependence of so2 emissions a panel dataset of 30 provinces from 2008 to 2013 is utilized to estimate the panel spatial durbin models the main findings of this study are that so2 emissions can be effectively reduced by government spending on environmental protection and that the relationship between so2 emissions and gross regional product grp per capita in china is cubic polynomial n shaped in addition as direct investment from foreign countries toward china increases so2 emissions will be reduced the trade factor also plays an important and negative role in so2 emissions provinces with higher shares of secondary industries to total grp will have more so2 emissions the investment completed in the treatment of industrial pollution in the private sector can effectively reduce so2 emissions and a higher population density causes a reduction in so2 emissions the coefficient of spatial autocorrelation is statistically positive confirming a positive spatial correlation also meaning a spatial competition of so2 emissions among provinces in china all these conclusions are consistent with those in previous works and with our expectations and remain the same while a two stage procedure is applied to cope with the potential endogeneity problem of grp with the exception of the effect of population density

students perceptions of teacher biases experimental economics in schools we put forward a new experimental economics design with monetary incentives to estimate students perceptions of grading discrimination we use this design in a large field experiment which involved 1 200 british students in grade 8 classrooms across 29 schools in this design students are given an endowment they can invest on a task where payoff depends on performance the task is a written verbal test which is graded non anonymously by their teacher in a random half of the classrooms and graded anonymously by an external examiner in the other random half of the classrooms we find significant evidence that students choices reflect perceptions of biases in teachers grading practices our results show systematic gender interaction effects male students invest less with female teachers than with male teachers while female students invest more with male teachers than with female teachers interestingly female students perceptions are not in line with actual discrimination teachers tend to give better grades to students of their own gender results do not suggest that ethnicity and socioeconomic status play a role

equilibrium analysis of supply chain structures under power imbalance abstract this paper investigates the implications of channel power on supply chain stability in a setting where multiple suppliers sell substitutable products through a common retailer such supply chains have been traditionally analyzed as one or two stage stackelberg non cooperative games with all suppliers sharing balanced equal decision making power in this paper we relax this assumption and formulate game theoretic models to examine scenarios where one supplier can act as the stackelberg leader consequently we analyze new supply chain structures and introduce the notion of structure dominance a novel approach to analyze the performance of supply chains that has practical implications thus a decision maker can employ the concepts of structure dominance to determine whether there exist supply chain scenarios that are more stable than others i e less prone to power reconfigurations at both agent and group level we find that power imbalance causes significant declines in supply chain profits and the more balanced the agents are the higher their profits when demand is linear regardless of product competition it develops that neither the manufacturer stackelberg nor the retailer stackelberg supply chains are stable structures in our generalized setting but that structures where power is equally split between agents provide for best stability and performance

confronting the environmental kuznets curve t he environmental kuznets curve posits an inverted u relationship between pollution and economic development kuznets s name was apparently attached to the curve by grossman and krueger 1993 who noted its resemblance to kuznets s inverted u relationship between income inequality and development in the first stage of industrialization pollution in the environmental kuznets curve world grows rapidly because people are more interested in jobs and income than clean air and water communities are too poor to pay for abatement and environmental regulation is correspondingly weak the balance shifts as income rises leading industrial sectors become cleaner people value the environment more highly and regulatory institutions become more effective along the curve pollution levels off in the middle income range and then falls toward pre industrial levels in wealthy societies the environmental kuznets curve model has elicited conflicting reactions from researchers and policymakers applied econometricians have generally accepted the basic tenets of the model and focused on measuring its parameters their regressions typically fitted to cross sectional observations across countries or regions suggest that air and water pollution increase with development until per capita income reaches a range of 5000 to 8000 when income rises beyond that level pollution starts to decline as shown in the conventional ekc line in figure 1 in developing countries some policymakers have interpreted such results as conveying a message about priorities grow first then clean up numerous critics have challenged the conventional environmental kuznets curve both as a representation of what actually happens in the development process and as a policy prescription some pessimistic critics argue that crosssectional evidence for the environmental kuznets curve is nothing more than a

the marketing channel as an equilibrium set of contracts nash bargaining theory and recent developments in economic contract theory are employed in the analysis of the marketing channels individual dyadic contracts involving payment schedules between members of a simple 3 level channel are investigated with particular reference to monitoring problems and intrachannel power relations the interrelations between individual contracts are examined and the equilibrium set of contracts constituting the channel derived the performance of the channel in terms of risk sharing allocative efficiency and the distribution of gains is then evaluated it is found that the risk aversion of channel members and the cost of monitoring and enforcement affect channel efficiency and that under certain types of interdependencies and externalities the nature of the power structure is crucial to channel efficiency

managing channel profits a channel of distribution consists of different channel members each having his own decision variables however each channel member s decisions do affect the other channel members profits and as a consequence actions a lack of coordination of these decisions can lead to undesirable consequences for example in the simple manufacturer retailer consumer channel uncoordinated and independent channel members decisions over margins result in a higher price paid by the consumer than if those decisions were coordinated in addition the ensuing suboptimal volume leads to lower profits for both the manufacturer and the retailer this paper explores the problems inherent in channel coordination we address the following questions what is the effect of channel coordination what causes a lack of coordination in the channel how difficult is it to achieve channel coordination what mechanisms exist which can achieve channel coordination what are the strengths and weaknesses of these mechanism what is the role of nonprice variables e g manufacturer advertising retailer shelf space in coordination does the lack of coordination affect normative implications from in store experimentation can quantity discounts be a coordination mechanism are some marketing practices actually disguised quantity discounts we review the literature and present a simple formulation illustrating the roots of the coordination problem we then derive the form of the quantity discount schedule that results in optimum channel profits this article was originally published in marketing science volume 2 issue 3 pages 239 272 in 1983

pride and prejudice using ethnic sounding names and inter ethnic marriages to identify labour market discrimination labour markets discriminate against workers with particular ethnic sounding names we use non random sorting into interethnic marriage and salient differences between sephardic and ashkenazi surnames to evaluate the causal impact of sephardic affiliation on wages using the 1995 israeli census we estimate the effect of a sephardic sounding surname on wages we first compare the wages of israeli jewish males born to sephardic fathers and ashkenazi mothers sa who are more likely to carry a sephardic surname with the wages of israeli jewish males born to ashkenazi fathers and sephardic mothers as we find that israeli labor markets discriminate based on perceived ethnicity sa workers earn significantly less than their as counterparts we then exploit the custom of women to adopt their husbands surnames to disentangle actual ethnicity from the ethnicity perceived by the market consistent with ethnic discrimination based on surnames we find that it is father in law s ethnicity rather than father s ethnicity that shapes female wage rates finally we find that labor markets discriminate based on surname only when those names provide additional information about ethnicity when ethnicity can be discerned from skin tone surnames do not provide additional explanatory power with respect to wages

moving to opportunity in boston early results of a randomized mobility experiment this paper examines the short run impacts of a change in residential neighborhood on the well being of low income families using evidence from a program in which eligibility for a housing voucher was determined by random lottery we examine the experiences of households at the boston site of moving to opportunity mto a demonstration program in five cities families in high poverty public housing projects applied to mto and were assigned by lottery to one of three groups experimental offered mobility counseling and a section 8 subsidy valid only in a census tract with a poverty rate of less than 10 percent section 8 comparison offered a geographically unrestricted section 8 subsidy or control offered no new assistance but continued to be eligible for public housing our quantitative analyses of program impacts uses data on 540 families from a baseline survey at program enrollment a follow up survey administered l to 3 5 years after random assignment and state administrative data on earnings and welfare receipt 48 percent of the experimental group and 62 percent of the section 8 comparison group moved through the mto program one to three years after program entry families in both treatment groups were more likely to be residing in neighborhoods with low poverty rates and high education levels than were families in the control group however while members of the experimental group were much more likely to be residing in suburban communities than were those in the section 8 group the lower program take up rate among the experimental group resulted in more families remaining in the most distressed communities households in both treatment groups experienced improvements in multiple measures of well being relative to the control group including increased safety improved health among household heads and fewer behavior problems among boys experimental group children were also less likely to be a victim of a personal crime to be injured or to experience an asthma attack there are no significant impacts of either mto treatment on the employment earnings or welfare receipt of household heads in the first three years after random assignment

on credible delegation by oligopolists a discussion of distribution channel management several papers in the recent marketing literature have suggested that delegation in distribution e g the use of independent middlemen helps manufacturers to precommit strategically to profit enhancing competitive actions further the literature suggests that the profitability of such actions depends on market structure we challenge these conclusions here this is done in two steps first we perform an analysis of the entire class of models which have been used in the literature using internally consistent assumptions about market structure and contracting the only subgame perfect equilibrium is one in which all distribution channels have infinitely many levels of delegation obviously this is not what we see in the real world next we relax a key hidden assumption namely that all intra channel agreements are observable to competitors without this assumption the usual results unravel unless channel members can offer credible guarantees that unobservable agreements do not exist the strategic effects of delegation disappear since these guarantees are virtually impossible to maintain credibly we would expect to reject the hypothesis in the earlier literature relating channel structure to competition in an empirical study controlling for observability we conclude that mechanisms other than strategic ones must be responsible for the existence of delegated channels and make some suggestions about promising avenues for future theory research in channel structure

strategic decentralization in channels the purpose of this paper is to understand the effect of strategic interaction on a manufacturer s channel structure decision in the model i analyze if there were no strategic interaction then the manufacturer would prefer vertical integration to decentralization with strategic interaction however decentralization can be a nash equilibrium strategy as mcguire and staein mcguire timothy richard staelin 1983a an industry equilibrium analysis of downstream vertical integration marketing sci 2spring 161 192 showed so the question arises what is it about strategic interaction that makes decentralization a nash equilibrium strategy the answer i give is that strategic interaction makes it possible for a manufacturer s retail demand curve to rise when he decentralizes i show that this raising of the demand curve on decentralization can happen only if one of the following mutually exclusive conditions is satisfied 1 the manufacturers products are demand substitutes at the retail level and strategic complements at the manufacturer or retailer levels 2 the manufacturer s products are demand complements at the retail level and strategic substitutes at the manufacturer or retailer levels strategic complementarity at the retailer manufacturer level means that if one retailer manufacturer raises his price then the other retailer manufacturer would raise his price as well strategic substitutability is just the opposite these results show that what is important for decentralization to occur is not how demand substitutable the two manufacturers products are as one might have thought from earlier works in the literature but rather the nature of coupling between demand dependence and strategic dependence

gender role attitudes and the labour market outcomes of women across oecd countries this paper uses data from the world value surveys 1990 1995 1999 to investigate the impact of gender role attitudes and work values on women s labour market outcomes across 25 oecd countries anti egalitarian views are found to display the strongest negative association with female employment rates and the gender pay gap these views are however softening among recent cohorts on the other hand perceptions of women s role as homemakers which are likely formed in youth and linked to religious ideology are more persistent over time they could be implicated in the recent slowdown of the gender convergence in pay finally the unavoidable clash between family values and egalitarian views that takes the form of an inner conflict for many women the so called mother s guilt is another obstacle in the path towards greater gender equality in the labour market copyright 2005 oxford university press

reexamining the empirical evidence for an environmental kuznets curve this paper uses an updated and revised panel data set on ambient air pollution in cities worldwide to examine the robustness of the evidence for the existence of an inverted u shaped relationship between national income and pollution we test the sensitivity of the pollution income relationship to functional forms to additional covariates and to changes in the nations cities and years sampled we find that the results are highly sensitive to these changes and conclude that there is little empirical support for an inverted u shaped relationship between several important air pollutants and national income in these data

competing manufacturers in a retail supply chain on contractual form and coordination it is common for a retailer to sell products from competing manufacturers how then should the firms manage their contract negotiations the supply chain coordination literature focuses either on a single manufacturer selling to a single retailer or one manufacturer selling to many possibly competing retailers we find that some key conclusions from those market structures do not apply in our setting where multiple manufacturers sell through a single retailer we allow the manufacturers to compete for the retailer s business using one of three types of contracts a wholesale price contract a quantity discount contract or a two part tariff it is well known that the latter two more sophisticated contracts enable the manufacturer to coordinate the supply chain thereby maximizing the profits available to the firms more importantly they allow the manufacturer to extract rents from the retailer in theory allowing the manufacturer to leave the retailer with only her reservation profit however we show that in our market structure these two sophisticated contracts force the manufacturers to compete more aggressively relative to when they only offer wholesale price contracts and this may leave them worse off and the retailer substantially better off in other words although in a serial supply chain a retailer may have just cause to fear quantity discounts and two part tariffs a retailer may actually prefer those contracts when offered by competing manufacturers we conclude that the properties a contractual form exhibits in a one manufacturer supply chain may not carry over to the realistic setting in which multiple manufacturers must compete to sell their goods through the same retailer

trust ethnic diversity and personal contact a field experiment abstract we study how close personal contact with minorities affects in group and out group trust in a field experiment in the armed forces soldiers are randomly assigned to rooms with or without ethnic minorities at the end of the recruit period we measure trust by using a trust game results indicate that close personal contact with minorities increases trust towards a generic immigrant we replicate the result that individuals coming from more ethnically diverse areas trust minorities less but random assignment to interact with minority soldiers removes this negative correlation we conclude that social integration involving personal contact can reduce negative effects of ethnic diversity on trust

a meta analysis of multibrand multioutlet channel systems in today s multibrand multichannel marketplace optimal channel design involves issues such as distribution intensity channel exclusivity vertical and horizontal coordination and online offline mixed structures we investigate how a firm s choice in these design issues affects its profitability under varying levels of brand and outlet differentiation our spatial model explicitly captures heterogeneous consumer preference for brand position store location and outlet type under various consumer behavior assumptions we apply this same underlying model to 10 different channel structures deriving associated demand functions and equilibrium solutions we perform a meta analysis over the entire set of results to estimate a general model that summarizes the linkages among the factors shaping optimal channel structure decisions in a multibrand multioutlet market this general model efficiently describes the complex interactions of channel characteristics with industry structure and consumer characteristics providing new findings as well as greater clarity to some results in the literature a predictive analysis applied to additional channel structures exhibits strong generalizability in qualitative findings

endogenous peer effects local aggregate or local average a b s t r a c t we develop a unified model embedding different behavioral mechanisms of social interac tions and design a statistical model selection test to differentiate between them in empirical applications this framework is applied to study peer effects in education effort in study ing and sport activities for adolescents in the united states we find that for education students tend to conform to the social norm of their friends while for sport activities both the social multiplier and the social norm effect matter

channel redistribution with direct selling abstract it seems nowadays that a company can be considered either a pure direct such as amazon com and dell computers or an adopted direct like barnes and noble for example an adopted direct company s decision to directly sell on line has become a fashionable choice but the results of such choice differ drastically glorious success mixed with pathetic failure one of the pending issues has been the channel redistribution strategy as whether to entirely switch to direct sell or to maintain a combination of both in this paper we develop a dynamic channel diffusion model and analyze how the sales will redistribute between the two channels in a given time variant marketplace this paper provides two major contributions first we obtain the existence of a steady state redistribution between the two channels and the necessary conditions for this existence second we establish measures of industry specific suitability for on line business operations in short our results concur with the theory it changes the way of doing business but does not change the business itself

persistent parochialism trust and exclusion in ethnic networks decentralized groups such as close knit residential neighborhoods and ethnically linked businesses often achieve high levels of cooperation while engaging in exclusionary practices that we call parochialism we investigate the contribution of within group cultural affinity to the ability of parochial groups to cooperate in social dilemmas we analyze parochial networks in which the losses incurred by not trading with outsiders are offset by an enhanced ability to enforce informal contracts by fostering trust among insiders we show that there is a range of degrees of parochialism for which parochial networks can coexist with an anonymous market offering unrestricted trading opportunities

breaking the glass ceiling the effect of board quotas on female labor market outcomes in norway in late 2003 norway passed a law mandating 40 representation of each gender on the board of public limited liability companies the primary objective of this reform was to increase the representation of women in top positions in the corporate sector and decrease the gender disparity in earnings within that sector we document that the women appointed to these boards post reform were observably more qualified than their female predecessors along many dimensions and that the gender gap in earnings within boards fell substantially however we see no robust evidence that the reform benefited the larger set of women employed in the companies subject to the quota moreover the reform had no clear impact on highly qualified women whose qualifications mirror those of board members but who were not appointed to boards finally we find mixed support for the view that the reform affected the decisions of young women while the reform was not accompanied by any change in female enrollment in business education programmes we do see some improvements in labour market outcomes for young women with graduate business degrees in their early career stages however we observe similar improvements for young women with graduate science degrees suggesting this may not be due to the reform overall seven years after the board quota policy fully came into effect we conclude that it had very little discernible impact on women in business beyond its direct effect on the women who made it into boardrooms

product line pricing in a supply chain a vertically integrated channel would prefer to coordinate the pricing of its products in this paper we investigate drivers of product line pricing decisions in a bilateral monopoly where a manufacturer produces and sells two substitutable or complementary products to a retailer in a two stage game each firm commits credibly in the first stage to a pricing scheme within its own organization product line pricing plp or nonproduct line pricing nplp in the second stage depending on the relative balance of power in the supply chain the firms engage in either a nash or a leader follower pricing game we study the equilibrium of the two stage game under a general symmetric demand function with strategic interaction between firms a firm may choose nplp as the equilibrium pricing strategy in particular when the second stage is a leader follower game the price leader chooses plp and the follower may choose nplp only if the inefficiency of using nplp empowers the follower by increasing the demand sensitivity to the leader s margin when the second stage is a vertical nash game whether nplp occurs in equilibrium depends on the nature of coupling between demand interdependence and vertical strategic dependence nplp can be an equilibrium onlyif products are demand substitutes complements and vertical strategic dependencies are complementary substitutable we find that prisoner s dilemma exists in the first stage for both types of second stage pricing games in those cases one firm may have the incentive to commit to a pricing scheme in the first stage prior to its channel partner and steer the supply chain away from prisoner s dilemma

on the origins of gender roles women and the plough the study examines the historical origins of existing cross cultural differences in beliefs and values regarding the appropriate role of women in society we test the hypothesis that traditional agricultural practices influenced the historical gender division of labor and the evolution of gender norms we find that consistent with existing hypotheses the descendants of societies that traditionally practiced plough agriculture today have less equal gender norms measured using reported gender role attitudes and female participation in the workplace politics and entrepreneurial activities our results hold looking across countries across districts within countries and across ethnicities within districts to test for the importance of cultural persistence we examine the children of immigrants living in europe and the united states we find that even among these individuals all born and raised in the same country those with a heritage of traditional plough use exhibit less equal beliefs about gender roles today jel codes d03 j16 n30 copyright 2013 oxford university press

is environmental degradation an inevitable consequence of economic growth tunneling through the environmental kuznets curve abstract economywide reforms often contribute simultaneously to economic social and environmental gains however unintended adverse side effects occur in many cases when such growth inducing reforms are undertaken while neglecting other policy market or institutional imperfections the remedy does not generally require reversal of the original economywide reforms but rather the ex ante implementation of additional complementary measures that remove such imperfections the ekc approach seeks to relate the state of the environment to the stage of development developing countries could learn from the experiences of industrialized nations and restructure growth and development to tunnel through any potential ekc thereby avoiding going through the same stages of growth that involve relatively high and even irreversible levels of environmental harm an environmentally adjusted measure of national income could significantly change the shape of the development environment relationship recommendations for decision making include actively seeking win win policies that simultaneously yield both economic and environmental gains pre empting environmental harm through ex ante remedial measures and fine tuning reform policies to avoid severe environmental damage the adoption of more sustainable policies will facilitate the attainment of higher levels of development at a lower environmental cost

towards an integrated framework for development and environment policy the dynamics of environmental kuznets curves abstract environmental kuznets curves ekcs have recently received considerable attention in development and environment policy but little is known on how the interaction between ecological and economic factors may result in an ekc or other qualitatively different outcomes we introduce a restricted class of vector valued differential equations for representing the evolution of socioeconomic and environmental variables which influence or are influenced by the process of economic development our model includes not only the complete path of each variable over time but also the highly critical interactions among multiple variables we demonstrate analytically and numerically that among a multiplicity of possible outcomes an inverted u pattern can only be obtained under specific circumstances and requires attention to the multiple factors which form the economic environmental system rather than a single dominant one

channel coordination when retailers compete this paper explores channel coordination by a manufacturer that sells through competing retailers and that treats these retailers equally as required by the robinson patman act the authors show that in general there exists no single two part tariff with a constant per unit charge that will duplicate the behavioral results i e prices quantities and channel profits that are obtained by a vertically integrated system that is the channel cannot be coordinated except in the trivial cases of identical or noncompeting retailers however an appropriately specified quantity discount schedule will enable the channel to earn the same profits generated by a vertically integrated system conditions are derived under which a manufacturer will prefer to offer various two part tariffs with constant per unit charges instead of the channel coordinating quantity discount schedule the authors also establish the existence of a menu of two part tariffs that mimics all results of a vertically integrated system however only under stringent conditions will retailers select the appropriate tariff from the menu when these conditions are not satisfied the channel is worse off than in the case of a single second best tariff it is also demonstrated that under a wide range of parametric values the manufacturer will prefer to offer the second best two part tariff rather than a menu of two part tariffs that could maximize channel profits

an industry equilibrium analysis of downstream vertical integration this paper investigates the effect of product substitutability on nash equilibrium distribution structures in a duopoly where each manufacturer distributes its goods through a single exclusive retailer which may be either a franchised outlet or a factory store static linear demand and cost functions are assumed and a number of rules about players expectations of competitors behavior are examined it is found that for most specifications product substitutability does influence the equilibrium distribution structure for low degrees of substitutability each manufacturer will distribute its product through a company store for more highly competitive goods manufacturers will be more likely to use a decentralized distribution system this article was originally published in marketing science volume 2 issue 2 pages 161 191 in 1983

note channel of distribution profits when channel members form conjectures it is well known that lower channel profits are achieved in the bilateral manufacturer reseller monopoly if manufacturer and reseller independently optimize their respective profits they take each other s decisions as given i e adopt decision rules that ignore their influence on the other channel member higher profits are achieved if they coordinate their profit maximizing decisions consequently there is an economic justification for 1 vertical integration that by definition prevents conflicting profit objectives or 2 contracts that change channel members incentives to the compatible objectives of shares of total channel profits this paper investigates the possibility that coordination might take place without formal arrangements like vertical integration or contracts the reason for this contention is the casual observation that channel members are often acutely aware of the interdependencies between channel participants we might thus expect that they will form conjectures about other channel members reactions to their own actions we show that rational conjectures lead profit maximizing channel members to adopt modified decisions rules can such conjectural decision making create at least partially channel coordination or cooperation in other words can channel members deviate from the nash equilibrium and thus achieve greater profits the answer given in this paper is a conditional yes

a general theory of pass through in channels with category management and retail competition i provide a general formulation of the channel pass through problem as a comparative static of the retail price equilibrium and i analyze the impact of category management and retail competition on pass through focusing on brand and retailer differences and the nature of the cost change being passed through whether it is brand specific retailer specific both or neither with category management a retailer s response to a brand specific cost change is not limited to that brand in general a retailer will also change the prices of other brands the cross brand effect can be positive or negative and depending on its sign it either enhances or attenuates pass through i explain the cross brand effect as an interaction between two forces a demand substitution force that pushes for a negative cross brand effect and a strategic complementarity force that pushes for a positive cross brand effect retail competition adds another layer of strategic complementarity causing other retailers to respond even for retailer specific cost changes and increasing pass through of categorywide cost changes but its effect for brand specific cost changes is ambiguous i apply the theory to two commonly used demand functions linear demand and nested logit and show that they have significantly different pass through properties the paper concludes with a discussion of how the theory relates to the empirical literature including the companion piece by besanko et al besanko d j p duba s gupta 2005 own brand and cross brand retail pass through marketing sci 24 1 123 137

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

social norms savings behavior and growth we argue that many goods and decisions are not allocated or made through markets we interpret an agent s status as a ranking device that determines how well he or she fares in the nonmarket sector the existence of a nonmarket sector can endogenously generate a concern for relative position in for example the income distribution so that higher income implies higher status moreover it can naturally yield multiple equilibria it is thus possible to explain differences in growth rates across countries without recourse to differences in underlying preferences technologies or endowments different social organizations lead to different reduced form preferences which lead to different growth rates

is there convergence in per capita so2 emissions in china an empirical study using city level panel data abstract as china s economy has grown rapidly in recent years china s environmental pollution has become increasingly significant among all the traditional pollutants sulfur dioxide has been monitored by the chinese government since the 1990s in this study china s city level panel data between 2002 and 2012 are utilized to investigate the existence of convergence in per capita sulfur dioxide emissions across chinese cities the conventional estimation methods for convergence suffer from an endogeneity problem and therefore produce biased results to address the endogeneity problem and allow for dynamics dynamic panel data estimators are utilized and the static estimation results are conducted as a robustness check in addition the influential factors for convergence are examined the empirical results indicate that in the chosen sample period there were absolute and conditional convergences in per capita sulfur dioxide emissions across cities within the whole nation as well as in the eastern western and central regions of china because per capita gross domestic product and the ratio of secondary industry to gross domestic product are both positively related with per capita sulfur dioxide emissions higher income per capita and greater importance of the secondary industry would cause the convergence speed to be lower therefore the most straightforward policy implication for the empirical results is that the policies for controlling sulfur dioxide emissions should be regionally differentiated for cities with high sulfur dioxide emissions per capita the regulation could be tight as the emissions would decrease faster because convergence exists however for cities with low sulfur dioxide emissions per capita the target for reducing emissions should not be excessively aggressive

does integration change gender attitudes the effect of randomly assigning women to traditionally male teams we examine whether exposure of men to women in a traditionally male dominated environment can change attitudes about mixed gender productivity gender roles and gender identity our context is the

on sequential commitment in the price dependent newsvendor model abstract we investigate the effect of sequential commitment in the decentralized newsvendor model with price dependent demand sequential commitment allows the self profit maximizing parties to commit to contract parameters e g wholesale price retail price buyback price and order quantity sequentially and alternately and we investigate its effect on the equilibrium profits of the channel and its members sequential commitment introduces more flexibility to contracting in the supply chain and our analysis can provide some insight to channel members who follow a bargaining process to determine the values of contract parameters we show that the introduction of sequential commitment to the price dependent pd newsvendor model with buybacks can significantly improve the manufacturer s and the channel expected profits but it can also decrease the retailer s expected profit finally we demonstrate that with sequential commitment under some conditions the choice of the first mover is endogenized and we identify the unique sequence of commitments by channel members that would arise in equilibrium

comment managing channel profits comment in a recent paper in this journal jeuland and shugan jeuland a s shugan 1983 managing channel profits marketing sci 2 summer 239 272 proposed a quantity discount schedule as a way of coordinating a channel as they put it on p 253 of their paper a quantity discount schedule which would fix the retailer s and hence the manufacturer s profits to some fixed linear function of total channel profits would lead the channel to maximize profits the purpose of this note is to show that a quantity discount schedule is not necessary for channel coordination

a test of environmental kuznets curve for haze pollution in china evidence from the penal data of 27 capital cities abstract the mounting environmental crisis especially the large scale and continuous haze pollution is the most pressing challenge for china during rapid urbanization process this study is aimed at examining the relationship between haze pollution and economic growth and its turning points for different regions in china based on the panel data of 27 capital cities and municipalities in china during 2011 2015 we constructed the parameter estimation model after conducting the unit root cointegration and hausman tests based on the basic and extended models we find that the relationship between haze pollution and economic growth in china is not a typical inverted u shaped environmental kuznet curve ekc by introducing variables such as industrial structure foreign trade and energy intensity this study demonstrates that adjusting industrial structure and improving energy efficiency are effective means for haze pollution control grouping regressions reveal that regional differences exist in the relationships between haze pollution and economic growth and their tuning points for instance there was a u shaped relationship for the central region while there were inverted n shaped relationships for eastern western and northeastern regions policy implications are thus summarized for different regions in terms of balancing economic growth and environmental protection

pricing decisions for complementary products with firms different market powers abstract this article reports the results of a study that explores the pricing problems with regard to two complementary products in a supply chain with two manufacturers and one common retailer the authors establish five pricing models under decentralized decision cases including the ms bertrand ms stackelberg rs bertrand rs stackelberg and ng models with consideration of different market power structures among channel members by applying a game theoretical approach corresponding analytic solutions are obtained then by comparing the maximum profits and optimal pricing decisions obtained in different decision cases interesting and valuable managerial insights are established

the effects of social networks on employment and inequality we develop a model where agents obtain information about job opportunities through an explicitly modeled network of social contacts we show that employment is positively correlated across time and agents moreover unemployment exhibits duration dependence the probability of obtaining a job decreases in the length of time that an agent has been unemployed finally we examine inequality between two groups if staying in the labor market is costly and one group starts with a worse employment status then that group s drop out rate will be higher and their employment prospects will be persistently below that of the other group

distribution channels an extension of exclusive retailership the underlying channel structure in most studies to date has consisted either of exclusive dealers that sell only one manufacturer s brand or of a single retailer selling multiple brands little attention has been given to the larger segment of most consumer goods markets in which retailers compete to sell multiple brands at the same location this research seeks to add to the growing literature of channel competition by analyzing three channel structures the least constrained of which deals with two competing manufacturers and two retailers each of whom distributes both products in a noncooperative game with two nash s and one stackleberg equilibrium using differentiated products and a linear demand function we introduce the concept of store substitutability a measure corresponding to product substitutability representing competitiveness at the retail level between the two retailers we are able to obtain closed form solutions for all cases we show that the presence of competitive effects at both retail and manufacturer levels of distribution has a significant impact on profits and prices we also study the effects of various power relationships in the channel furthermore we compare these results to those obtained by previous research finally we propose some testable implications and suggest avenues for future research

a dynamic model of the environmental kuznets curve turning point and public policy we set up a simple dynamic macroeconomic model with i polluting consumption and a preference for a clean environment ii increasing returns in abatement giving rise to an ekc and iii sustained growth resulting from a linear final output technology there are two sorts of market failures caused by external effects associated with consumption and environmental effort the model is employed to investigate the determinants of the turning point and the cost effectiveness of different public policies aimed at a reduction of the environmental burden moreover the model offers a potential explanation of an n shaped pollution income relation it is shown that the model is compatible with most empirical regularities on economic growth and the environment

gender identity and relative income within households band s income we argue that this pattern is best explained by gender identity norms which induce an aversion to a situation where the wife earns more than her husband we present evidence that this aversion also impacts marriage formation the wife s labor force participation the wife s income conditional on working marriage satisfaction likelihood of divorce and the division of home production within marriage markets when a randomly chosen woman becomes more likely to earn more than a randomly chosen man marriage rates decline in couples where the wife s potential income is likely to exceed the husband s the wife is less likely to be in the labor force and earns less than her potential if she does work in couples where the wife earns more than the husband the wife spends more time on household chores moreover those couples are less satisfied with their marriage and are more likely to divorce these patterns hold both cross sectionally and within couples over time

coordinated decisions for substitutable products in a common retailer supply chain abstract this paper studies coordination mechanisms in a supply chain which consists of two suppliers with capacity uncertainties selling differential yet substitutable products through a common retailer who faces price sensitive random demand of these two products we develop in a noncompetitive setting three coordination models revenue sharing return policy and combination of revenue sharing and return policy and contrast them with a basic and uncoordinated model we are able to establish the ordinal relationship among the retailer s ordering and pricing decisions and analytically compare the performances between certain models when two suppliers are identical we find that the retailer s ordering and pricing decisions in the model with return policy in the case of identical suppliers are independent of demand or supply uncertainty our numerical results reveal that the performances of coordination models in the case of nonidentical suppliers resemble those in the case of identical suppliers we find that the retailer will place a larger order quantity in models where her average cost per unit sold is smaller we also find that product substitutability and uncertainties have different effects on chain performances

strategic interactions between channel structure and demand enhancing services in this paper we investigate how opportunities to invest in demand enhancing services for a product line affect the interactions between a manufacturer and her dealer many demand enhancing services e g after sales support warranty repair etc can be provided either by the manufacturer or they can be delegated to the dealer we first show that when a manufacturer retains control of such services the dealer will have an incentive to choose a decentralized organizational structure as a means of committing to non product line pricing since this will encourage the manufacturer to invest more in demand enhancing services we then consider a game that is played between the manufacturer and the dealer in which the dealer chooses between centralized product line pricing or decentralized non product line pricing operations and the manufacturer chooses between insourcing the services i e providing them herself or outsourcing them to the dealer we find that the equilibrium depends on which if any channel partner has the ability to act as a stackelberg leader if the dealer can move first then the equilibrium will always be outsourced services and centralized dealer operations however if either the manufacturer moves first or if neither partner can move first then the equilibrium can be either insourced services and decentralized dealer operations or outsourced service and centralized dealer operations

income inequality and pollution a reassessment of the environmental kuznets curve abstract improvements in some measures of air and water quality can accompany rising per capita income as illustrated by the so called environmental kuznets curve for pollution variables which show such a relationship we hypothesize that a more equitable distribution of power contributes to these outcomes by enhancing the influence on policy of those who bear the costs of pollution relative to the influence of those who benefit from pollution generating activities an empirical analysis of international variations in seven indicators of air and water quality supports this hypothesis literacy political rights and civil liberties are found to have particularly strong effects on environmental quality in low income countries

reply to managing channel profits comment we welcome moorthy s comment moorthy k s 1987 managing channel profits comment marketing sci 6 fall 375 379 it provides an opportunity to clarify several issues raised in our 1983 paper that paper was motivated by one concern channel coordination we believed that channel members benefit from coordination and that many institutional arrangements such as quantity discounts are actually coordinating mechanisms we developed a simple model to demonstrate our belief for historical accuracy mcguire and staelin cited by moorthy had already independently developed a useful model of duopolistic channel competition being unaware of their working paper our model not surprisingly differed from theirs both papers provide important but different insights into channel management

health benefits of tunneling through the chinese environmental kuznets curve ekc abstract in this paper we first add to what is a growing literature on the existence and nature of the environmental kuznets curve ekc model for developing countries by testing for the existence of an ekc for china using a panel data set of city specific annual ambient levels of so2 pollution we find some support for both the typical inverted u shaped relationship and an n shaped cubic configuration more significantly we then explore the possibility of china s tunneling through the ekc by using newer cleaner technologies and thereby avoiding some of the environmental degradation that had often accompanied economic growth specifically we estimate and economically value the health benefits realizable to chinese cities from successful efforts to tunnel under the ekc over the next generation

pricing decisions for substitutable products in a two echelon supply chain with firms different channel powers abstract pricing decisions for two substitutable products in a supply chain with one common retailer and two competitive manufacturers are considered in this paper the purpose of this paper is to analyze the effects of the two manufacturers different competitive strategies and the channel members different power structures on the optimal pricing decisions one centralized pricing model and seven decentralized pricing models are developed and the corresponding analytical equilibrium solutions are obtained by using game theoretic approach finally numerical studies are presented to illustrate the effectiveness of the theoretical results and to gain additional managerial insights

competition and cooperation in marketing channel choice theory and application this paper discusses the problem of choosing a vertical marketing channel in a product differentiated duopolistic market firms choose product price and the form of the marketing channel to maximize profits it is shown that integration of the marketing function results in greater price competition and lower prices than does the use of independent marketing middlemen the profitability of reducing price competition by using such middlemen is investigated two hypotheses that integration is negatively associated with the products substitutability and that symmetric channel structures are stable are tested in a preliminary way and supported with survey data from the international semiconductor industry

distribution channel strategies in a mixed market abstract this paper studies equilibrium channel strategies in a mixed market with a public firm and a private firm the public firm is concerned with social welfare while the private firm aims to maximize its own profit each firm decides whether to adopt an integrated or a decentralized channel we examine two standard market competition modes bertrand and cournot within each competition mode we consider two typical vertical contracts wholesale price and two part tariff contracts our results suggest that equilibrium channel structures depend on the market competition mode the vertical contract form and the level of product substitutability specifically the channel strategy of the private firm depends mainly on the vertical contract form under a two part tariff contract the private firm always chooses decentralization under a wholesale price contract the private firm chooses integration for most scenarios except for highly substitutable products under bertrand competition i e under very intense competition the channel strategy of the public firm depends mainly on the competition mode under bertrand competition the public firm always chooses decentralization under cournot competition the public firm always chooses the opposite of the private firm s strategy
