strategic capacity rationing to induce early purchases dynamic pricing offers the potential to increase revenues at the same time it creates an incentive for customers to strategize over the timing of their purchases a firm should ideally account for this behavior when making its pricing and stocking decisions in particular we investigate whether it is optimal for a firm to create rationing risk by deliberately understocking products then the resulting threat of shortages creates an incentive for customers to purchase early at higher prices but when does such a strategy make sense if it is profitable to create shortages what is the optimal amount of rationing risk to create we develop a stylized model to study this problem in our model customers have heterogeneous valuations for the firm s product and face declining prices over two periods customers are assumed to have identical risk preferences and know the price path and fill rate in each period via its capacity choice the firm is able to control the fill rate and hence the rationing risk faced by customers customers behave strategically and weigh the payoff of immediate purchases against the expected payoff of delaying their purchases we analyze the capacity choice that maximizes the firm s profits first we consider a monopoly market and characterize conditions under which rationing is optimal we examine how the optimal amount of rationing is affected by the magnitude of price changes over time and the degree of risk aversion among customers we then analyze an oligopoly version of the model and show that competition reduces the firms ability to profit from rationing indeed there exists a critical number of firms beyond which a rationing equilibrium cannot be supported

revenue management with strategic customers last minute selling and opaque selling companies in a variety of industries e g airlines hotels theaters often use last minute sales to dispose of unsold capacity although this may generate incremental revenues in the short term

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

statistical analysis and combination forecasting of environmental efficiency and its influential factors since china entered the wto 2002 2010 2012 abstract since china became a member of world trade organization wto its economy develops at a fast speed at the same time the environmental problem becomes more and more serious and increasingly affects economic development studying the factors that influence environmental efficiency has become an essential point in dealing with the relationship between economy and environment considering the differences in space and economic development among different districts this paper discusses the quantitative relationship among exports figure imports figure gdp per capita industrialization level fiscal decentralization and environmental efficiency of each chinese province by using statistical analysis furthermore this paper discusses differences among each district s influential factors from the perspective of spatial economics and makes combination forecast on the trend of environmental efficiency it also shows that the environmental efficiency of chinese provinces is generally at a low level in addition as the economic statuses of different provinces vary and the factors that influence environmental efficiency in different provinces also have significant differences each province should take certain measures to design the environmental protection policy in line with its local circumstance

dynamic pricing in the presence of social learning and strategic consumers when a product of uncertain quality is first introduced consumers may choose to strategically delay their purchasing decisions in anticipation of the product reviews of their peers this paper investigates how the presence of social learning affects the strategic interaction between a dynamic pricing monopolist and a forward looking consumer population within a simple two period model our analysis yields three main insights first we find that the presence of social learning has significant structural implications for optimal pricing policies in the absence of social learning decreasing price plans are always preferred by the firm by contrast in the presence of social learning we find that i if the firm commits to a price path ex ante preannounced pricing an increasing price plan is typically announced whereas ii if the firm adjusts price dynamically responsive pricing prices are initially low and may either rise or decline over time second we establish that under both preannounced an

research note trading up a strategic analysis of reference group effects reference groups influence product and brand evaluations especially when the product is a publicly consumed luxury good marketers of such luxury goods need to carefully balance two important social forces 1 the desire of leaders to distinguish themselves from followers and 2 the countervailing desire of followers to assimilate with leaders in this paper we examine the theoretical implications of these social forces for firm prices product design and target consumer selection we show that the presence of reference group effects can motivate firms to add costly features which provide limited or no functional benefit to consumers furthermore reference group effects can induce product proliferation on one hand and motivate firms to offer limited editions on the other hand we find that offering a limited edition can increase sales and profits in some cases reference group effects can even lead to a buying frenzy

does environmental regulation affect energy efficiency in china s thermal power generation empirical evidence from a slacks based dea model abstract data envelopment analysis dea has gained much popularity in performance measurement of power industry this paper presents a slack based measure approach to investigating the relationship between fossil fuel consumption and the environmental regulation of china s thermal power generation we first calculate the total factor energy efficiency without considering environmental constraints an environmental performance indicator is proposed through decomposing the total factor energy efficiency the proposed approach is then employed to examine whether environmental regulation affects the energy efficiency of china s thermal power generation we find that the environmental efficiency plays a significant role in affecting energy performance of china s thermal generation sector decreasing the discharge of major pollutants can improve both energy performance and environmental efficiency besides we also have three main findings 1 the energy efficiency and environmental efficiency were relatively low 2 the energy and environmental efficiency scores show great variations among provinces 3 both energy efficiency and environmental efficiency are of obvious geographical characteristics according to our findings we suggest some policy implications

joint pricing and production decisions with yield uncertainty and downconversion abstract we consider a firm who supplies two types of products high end and low end because of the uncertainty in the production process the yield rate of the high end products is uncertain the substandard high end products caused by the yield uncertainty can be transformed into the low end products with a certain cost we characterize the optimal pricing and production decisions and develop an algorithm to compute the optimal solution we also investigate the impact of the yield uncertainty on the firm s performance and explore how stability of market demand emergent fulfillment costs and downconversion cost influence this effect we find that i the profit of the firm deteriorates when the risk of the yield uncertainty is high in the face of yield uncertainty the firm prefers to decrease increase the production quantity of the high end low end products ii when the market demands are quite unstable the emergent fulfillment costs are low or the downconversion cost is high the firm has a low incentive to eliminate the yield uncertainty

the making of a hot product a signaling explanation of marketers scarcity strategy every marketer s dream is to create a hot product that customers would absolutely want to have thus generating considerable profit to the marketer according to one school of thought marketers should make products hard to get in order to create really hot products in this paper using a game theoretic model we investigate if such scarcity strategies can indeed be optimal while a scarcity strategy may appear to be a viable approach for making a firm s product successful further analysis raises some puzzling issues in particular it is not clear why a firm would not increase its price to get demand and supply in sync and increase its profit in the process we therefore offer a signaling explanation for the optimality of such strategies and show that a high quality seller may optimally choose to make the product scarce in order to credibly signal the quality of its product to uninformed customers our analysis indicates that a high quality seller optimally employs scarcity as a signaling device in product markets that are characterized ceteris paribus by a small difference in marginal cost between high and low quality products a low reservation price for a low quality product a greater heterogeneity in reservation prices for a high quality product and a moderate number of informed consumers our results provide a rationale for the fact that scarcity strategies are usually observed for discretionary or specialty products but not for commodity products staple products or new to the world products

generic fluid milk advertising demand expansion and supply response the case of new york city a transfer function was used to estimate the fluid milk demand equation of new york city the consumption effect of a generic fluid milk advertising program in the city was found to be positive and statistically significant the resulting higher blend price of milk was found to have a negligible effect on the subsequent supply of milk though being successful in generating positive returns on advertising it was found that a 35 reduction in the advertising expenditures would have been optimal in the marginal sense

multicriteria analysis in agricultural marketing the case of french olive oil market abstract agribusiness industries face a stiff competition originating mainly from the eu trade barrier s removal and the rapidly changing marketing environment of the single european market therefore certain need has been identified towards the development and proper utilization of updated market research tools and methodologies in the field of agricultural marketing the aim of this paper is to show the usefulness of multicriteria approach in analyzing consumer s preference data and its ability to support new product development processes by agricultural firms the paper outlines first the philosophy of agricultural marketing by emphasizing on the features which differentiate it from general marketing several methodological issues in agricultural marketing are then presented through a state of the art survey then the paper develops a consumer based methodology to support product development decisions where the key role is played to determine the preference model which explains a single consumer s ranking a decision support system summarizes the analysis on the whole set of interviewed consumers to prescribe the ideal profile of a new product and to simulate its penetration strategy into the market results from the application of the methodology to a survey data base coming from the paris olive oil market are presented finally the paper concludes with some recommendations about marketing practice in agribusiness

optimal design of social comparison effects setting reference groups and reference points in this paper we study how social planners should exploit social comparisons to pursue their objectives we consider two modes of social comparison referred to as behind averse and ahead seeking behaviors depending on whether individuals experience a utility loss from underperforming or a utility gain from overperforming relative to their peers modeling social comparison as a game between players we find that ahead seeking behavior leads to output polarization whereas behind averse behavior leads to output clustering a social planner can mitigate these effects in two ways i by providing the full reference distribution of outputs instead of an aggregate reference point based on the average output and ii by assigning players into uniform rather than diverse reference groups social planners may thus need to tailor the reference structure to the predominant mode of social comparison and their objective a performance focused social planner may set the reference structure so as to maximize the output of either the top or the bottom player depending on whether she puts greater marginal weight to larger or smaller outputs when the social planner also cares about utility she faces a dilemma because performance optimization may not be aligned with utility maximization inevitably the social planner will have to confront equity issues because better performance may not reflect greater effort or greater ability this paper was accepted by serguei netessine operations management

did china s regional transport industry enjoy better carbon productivity under regulations despite rapid economic development the transport industry has been claimed to account for a major part of climate change this paper investigates total factor carbon sensitive productivity growth in the regional transport sector in china and decomposes its dynamic changes over time taking account of the regional heterogeneity of different provinces thus the contemporaneous metafrontier malmquist luenberger approach that combined with non radial directional distance functions is proposed and define a new indicator called the contemporaneous metafrontier malmquist luenberger carbon emission performance index cmml this total factor indicator includes the metafrontier efficiency change index mec the metafrontier technology change index mtc and the metafrontier technology gap change index tgc results show an about 4 increase in overall total factor carbon emission productivity during the period of 2000 2012 different growth patterns are also observed in the transport sector across different area of china in the eastern region the growth of carbon productivity is driven mainly by pure efficiency changes whereas the central region is driven mainly by innovations in the low carbon transport technology

consumption externality and yield uncertainty in the influenza vaccine supply chain interventions in demand and supply sides we study the impact of yield uncertainty supply side and self interested consumers demand side on the inefficiency in the influenza vaccine supply chain previous economic studies focusing on demand side find that the equilibrium demand is always less than the socially optimal demand because self interested individuals do not internalize the social benefit of protecting others via reduced infectiousness positive externality in contrast we show that the equilibrium demand can be greater than the socially optimal demand after accounting for the limited supply due to yield uncertainty and manufacturer s incentives the main driver for this result is a second negative externality self interested individuals ignore that vaccinating people with high infection costs is more beneficial for the society when supply is limited we show that the extent of the negative externality can be reduced through more efficient and less uncertain allocation mechanisms to investigate the relative effectiveness of government interventions on supply and demand sides under various demand and supply characteristics we construct two partially centralized scenarios where the social planner i e government intervenes either on the demand side or the supply side but not both we conduct an extensive numerical analysis this paper was accepted by yossi aviv operations management

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

limited edition products when and when not to offer them many brands today introduce limited edition le products as part of their product line however little is known about the conditions under which a brand should introduce an le product or the competitive implications of doing so we investigate this issue using a game theoretic model of a market where two brands compete for consumers who desire exclusivity our analysis shows that adding an le product has a positive direct effect on brand profits through the increased willingness of consumers to pay for such a product but also has a negative strategic effect by increasing price competition between brands these effects result in different conclusions depending on the nature of brand differentiation when brands differ in quality we show that only the high quality brand may gain in comparison to a scenario where there are no le products although a low quality brand may offer an le product as a defensive strategy its profits are lower than would be in a world without le products because of the negative strategic effect when we consider brands that are differentiated on a horizontal attribute such as taste we find that the negative strategic effects cause lower equilibrium profits if both brands introduce le products yet brands cannot avoid introducing le products because they face a prisoners dilemma

sustainability performance for brazilian electricity power industry an assessment integrating social economic and environmental issues the increased pressure on companies to address sustainability issues has resulted in the development of several voluntary corporate sustainability integration approaches the array of existing approaches is large and overwhelming resulting in companies not understanding what corporate sustainability really means for their businesses considering environmental economic and social issues this paper aims at assessing the performance of the brazilian electricity power industry in terms of its sustainability performance an analysis of global reporting initiative gri indicators for the energy sector lead to an assessment of its sustainability performance by applying data envelopment analysis dea specified with a directional distance function ddf five scenarios were created i flexible weights ii triple bottom line iii social issues iv economic issues and v environmental issues with considering i flexibility weights almost all companies are efficient we also found a significant difference when we compared i with the other four scenarios ii iii iv and v taking into account the triple bottom line scenario ii the results indicate that companies were less efficient when compared with the flexible weights scenario i taking into account the last three scenarios iii iv and v only four companies were considered as providing top benchmarks in sustainability performance

does government transparency contribute to improved eco efficiency performance an empirical study of 262 cities in china abstract considering the properties of environment from the perspective of a public good this paper aims to examine the relationship between government transparency and eco efficiency performance eep by applying a conditional slack based measure sbm model local linear regression llr and a nonparametric significance test we conduct an empirical analysis based on 262 cities in china during the period of 2005 2012 the results demonstrated that 1 the overall eco efficiency of china was low due to the fact that the eep scores of most of the cities were below 0 5 2 the eco efficiency performances of a majority of the municipalities sub provincial ms 3 there exists a nonlinear relationship between government transparency and eco efficiency performance in other words if the government information was more transparent it would be more beneficial to the improvement of eco efficiency and the phenomena were more significant in m s cities such as shanghai beijing and guangzhou policy implications are thus drawn in this paper for promoting eco efficiency improvement in china s m s cities and prefecture level cities

identification of endogenous social effects the reflection problem this paper examines the reflection problem that arises when a researcher observing the distribution of behaviour in a population tries to infer whether the average behaviour in some group influences the behaviour of the individuals that comprise the group it is found that inference is not possible unless the researcher has prior information specifying the compisition of reference groups if this information is available the prospects for inference depend critically on the population relationship between the variables defining reference groups and those directly affecting outcomes inference is difficult to implossible if these variables are functionally dependent or are statistically independent the prospects are better if the variables defining reference groups and those directly affecting outcomes are moderately related in the population

buyback contracts with price dependent demands effects of demand uncertainty chapter 2 examines buyback contracts in a supplier retailer supply chain where the retailer faces a price dependent downward sloping demand curve subject to uncertainty compared with classical research a fundamental difference of this research lies in its analytical examination of the effects of demand uncertainty on the applicability of buyback contracts to this end the research seeks to characterize the buyback contract model in terms of only demand uncertainty level with such a new research perspective some new and interesting findings are obtained for such issues as how demand uncertainty level affects the applicability of buyback practice and how to apply this practice to improve supply chain members own interests or the supply chain system s efficiency the research in this chapter demonstrates that the uncertainty level inherent in market demand can be a critical factor influencing the applicability of supply chain contracts as well as the contract s administrative cost cachon 2003 and the uncertainty type marvel and peck 1995

a note on probability distributions with increasing generalized failure rates distributions with an increasing generalized failure rate igfr have useful applications in pricing and supply chain contracting problems we provide alternative characterizations of the igfr property that lead to simplify verifying whether the igfr condition holds we also relate the limit of the generalized failure rate and the moments of a distribution

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

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

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

the operational advantages of threshold discounting offers we study threshold discounting or the practice of offering a discounted price service if at least a prespecified number of customers signal interest in it as pioneered by groupon we model a capacity constrained firm a random sized population of strategic customers a desirable hot period and a less desirable slow period compared to a more traditional approach slow period discounting or closure threshold discounting has two operational advantages first the contingent discount temporally balances demand when the market for the service is large and reduces supply of the service preserving higher margins when the market is small allowing the firm to respond to the service s unobserved market potential second activation of the threshold discount signals the market state and the consequent service availability to strategic customers inducing them into self selecting the consumption period to one that improves the firm s capacity utilization yet threshold discounting can be harmful in situations with chronically low demand in contrast with past work on strategic customers their presence is advantageous to firms in our context a calibrated numerical study shows that threshold discounting improves firm profits over a traditional approach by as much as 33 7 on average the online appendix is available at https doi org 10 1287 mnsc 2017 2740 this paper was accepted by yossi aviv operations management

purchasing pricing and quick response in the presence of strategic consumers we consider a retailer that sells a product with uncertain demand over a finite selling season the retailer sets an initial stocking quantity and at some predetermined point in the season optimally marks down remaining inventory we modify this classic setting by introducing three types of consumers myopic consumers who always purchase at the initial full price bargain hunting consumers who purchase only if the discounted price is sufficiently low and strategic consumers who strategically choose when to make their purchase a strategic consumer chooses between a purchase at the initial full price and a later purchase at an uncertain markdown price in equilibrium strategic consumers and the retailer make optimal decisions given their rational expectations regarding future prices availability of inventory and the behavior of other consumers we find that the retailer stocks less takes smaller price discounts and earns lower profit if strategic consumers are present than if there are no strategic consumers we find that a retailer should generally avoid committing to a price path over the season assuming such commitment is feasible committing to a markdown price or to not mark down at all is often too costly inventory may remain unsold even in the presence of strategic consumers the better approach is to be cautious with the initial quantity and then mark down optimally furthermore we discuss the value of quick response the ability to procure additional inventory after obtaining updated demand information albeit at a higher unit cost than the initial order we find that the value of quick response to a retailer is generally much greater in the presence of strategic consumers than without them on average 67 more valuable and as much as 558 more valuable in our sample in other words although it is well established in the literature that quick response provides value by allowing better matching of supply with demand it provides more value often substantially more value by allowing a retailer to control the negative consequences of strategic consumer behavior
