strategic segmentation of a market abstract when competing firms target information towards specific consumers through direct marketing activities complete segmentation of markets can result we analyze a two stage duopoly where prior to price competition each firm targets information to specific consumers and only consumers informed by a firm can buy from it this has the effect of endogenously determining market segments in a model of sales in equilibrium pure local monopoly emerges firms target and sell to mutually exclusive market segments when the cost of marketing approaches zero market shares reflect relative production efficiency equal shares when firms are symmetric this may not be the case when marketing cost is high

entry deterrence in stackelberg perfect equilibria this paper examines entry deterrence in a duopoly where the postentry game is stackelberg it is argued that in reality firms can use a broader range of precommitments than is allowed for in the literature this paper permits such precommitments and analyzes the perfect equilibria it also allows for the fact that there may be fixed costs associated not only with entry but with beginning production several interesting possibilities are explained including the existence of excess capacity and the holding of inventories even in the absence of any uncertainty copyright 1990 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

a theory of interlinked rural transactions this paper argues that the interlinking of labor output and credit contracts often observed in rural economies can be regarded as an attempt to improve allocative efficiency in the face of moral hazard it advances an economic explanation of the phenomenon which is rooted in the view that prevalent modes of transaction of which interlinked contracts are an example are shaped by technological considerations interlinking is shown to be an efficient economic response to unequally distributed information arising from the uncertainty which characterizes subsistence agriculture all pareto efficient allocations require a combination of wage cum output sharing with consumption credit contracts the analytical framework set up to demonstrate the results is used to examine the response of the contractual parameters to changes in i the returns to alternative occupations available to tenant laborers ii the cost of credit to the village economy and iii the riskiness of cultivation the analysis concludes that public policy to alleviate rural poverty must recognize the relationships between technological considerations and modes of transaction in the absence of a complete set of markets

does institutional quality matter for trade institutional conditions in a sectoral trade framework summary this article examines the extent to which national institutional quality affects bilateral sectoral trade flows as well as whether the conditioning role of institutions for trade has been waxing or waning with time based on a new trade theory framework we derive a sectoral gravity equation including novel variables corresponding to the exporter s labor competitiveness levels along with importer s price indices and sectoral incomes and analyze industry specific bilateral trade flows of 186 countries for the period 1996 2012 we address potential endogeneity and econometric drawbacks by means of the poisson pseudo maximum likelihood estimation methods the results indicate that both the institutional conditions at destination and the institutional distance between exporting and importing countries are relevant factors for bilateral trade moreover the effect associated with institutional conditions at destination moderately increases over time this is a robust outcome across economic sectors with higher values for agriculture and raw materials than for manufacturing and services

energy consumption in service industries challenging the myth of non materiality abstract this paper addresses the issue of energy consumption in service industries official energy statistics show that the amount of energy consumed in service industries is quite small and this is explained in the theoretical literature by the presumed intangibility of services our hypothesis however is that the energy consumed by services has been underestimated after identifying and analyzing the full range of sources of energy consumption in service industries we show that official energy statistics account for only a part of this consumption our work is based on a thorough rereading of the economics literature on services especially concerning the definition of services and the specificities of the service provision process done in light of our knowledge about energy consumption eventually using the 2007 french national transportation and travel survey we estimate one of the overlooked sources of energy consumption the one pertaining to mobility

location choice product proliferation and entry deterrence within a slightly modified version of hotelling s model we reconsider the claim that the threat of entry induces existing firms to produce a larger number of products than they would otherwise we show that entry deterrence although optimal need not be achieved through product proliferation in some cases the incumbent monopolist resorts to an entry deterring strategy based on location choice rather than product proliferation we also show that in some cases the number of products chosen by the incumbent facing the threat of entry is strictly greater than the minimum number required to deter entry

asymmetric price competition with price inertia in this article i analyze price competition under price inertia after setting prices sellers are unable to change them for a period of predetermined length but may delay price commitments indefinitely although most consumers consider the firms products to be perfect substitutes an arbitrarily small number of captive consumers display brand loyalty to a particular firm even when the competing brand is cheaper in this article i show that a firm with even slightly fewer captive consumers than its competitor achieves monopoly power over all remaining consumers

informative advertising with differentiated products in this paper we study the role of promotional expenditures by sellers in a model of product differentiation advertising conveys full and accurate information about the characteristics of products heterogeneous consumers who have no source of information other than advertisements seek to purchase the products that best fit their needs despite the roles played by advertising in improving the matching of products and consumers and in increasing the elasticity of demand faced by each firm we find that the market determined levels of advertising are excessive given the extent of diversity in the market we derive a promotional equilibrium based on a specific information transmission technology paying explicit attention to the structure of consumer information and its impact on firms demand curves this allows us to study the effects of changes in the advertising technology including an increased ability to target messages to specific groups of consumers on the equilibrium in the product market we find that decreased advertising costs may reduce profits by increasing the severity of price competition

poverty and inequality under income and price dispersions many policies simultaneously affect the distribution of prices and incomes in the economy moreover a bias may occur when there is a stochastic relationship between prices and incomes and this relationship is being ignored it is therefore important to dispose of an analytical framework for welfare analysis that could account for changes in this joint distribution how can the joint influences of price and income distributions on poverty and inequality indicators be analysed we offer a method to deal with this problem by using parametric formulae of poverty and inequality measures we propose statistical indicators for the levels variabilities and a statistical link of price indices and nominal living standards these indicators are consistent with an approximation of the problem based on a bivariate lognormal distribution of price indices and nominal living standards our analysis provides hints about the social welfare impact of economic shocks or policies affecting levels variabilities and correlation of prices and incomes intuitive insights are obtained while using arithmetic means and variances instead does not lead to illuminating results the role of price and income variabilities for poverty and inequality is more complex than generally expected with the possibility of several variation regimes empirical investigation of these statistics would guide social policies

advertising in competitive markets in this paper small firms sell a homogeneous good to small consumers under conditions of free entry but consumers receive price information only through firms advertising in equilibrium every firm on the continuous price distribution buys less advertising than is socially optimal the result is robust if firms advertise in just one medium if readers of different advertising media are positively correlated excess advertising can occur in media used exclusively to advertise discount prices copyright 1991 by american economic association

the provision of information in a bertrand oligopoly a two stage model of a homogeneous good oligopoly is constructed that is composed of a first stage determining costless information provision to consumers and then a second stage of price setting a perfect equilibrium is found that is characterized by les s than full information and by positive expected profits an alternati ve interpretation of the model is of firms deciding the proportion of contracts to tender for and then the prices at which the tenders wil l be made copyright 1993 by blackwell publishing ltd

an empirical test of the comparative and contributory negligence rules in accident law scholars in the field of law and economics have developed an extensive theoretical literature on the effects of liability rules in accident law but have done little testing of their theoretical models in this article i develop an empirically testable model of the incentives for injurers and victims to avoid accidents under both the older contributory negligence rule and the newer rule of comparative negligence the model takes account of the fact that in the automobile accident context drivers do not know in advance with whom they will be involved in an accident and whether they will be the injurer or the victim or both it also allows for uncertainty in legal decision making the model is tested using a data set of rear end automobile accidents litigated in court the results suggest first that incentives to take care to avoid accidents are stronger under the contributory negligence rule than under the newer rule of comparative negligence and second the incentives set up by the comparative negligence rule for drivers to avoid accidents are weaker than is economically efficient

interfirm bundled discounts as a collusive device this paper investigates whether and how firms competing in price with homogeneous goods i e bertrand competitors can achieve supernormal profits using interfirm bundled discounts by committing to offering price discounts conditional on the purchase of a specific brand of other differentiated good the homogeneous good suppliers can separate consumers into distinct groups such brand specific discounts help the firms relax competition and attain a collusive outcome consumers become worse o due to higher effective prices our result shows that in oligopolies it is feasible to leverage other s market power without excluding rivals

separable but not equal the location determinants of discrete services offshoring activities in this paper we explore the question of why firms offshore particular services to specific geographic locations we draw on research related to the unique characteristics of services in trade and commerce and more recent analyses of the transnational unbundling and spatial dispersion of business processes we move beyond a simple assessment of the cost sensitivity or relative sophistication of offshoring services and develop a typology emphasizing the degree to which offshoring services activities are interactive repetitive or innovative we suggest that the location of offshoring projects will depend on the particular mix of these attributes and test this assertion using a data set of 595 export oriented offshore services projects initiated from 2002 to 2005 by us and uk company parents in 45 developed and developing countries we find that offshore location choices greatly depend on these services characteristics and in sometimes surprising ways and draw implications from our findings for international business theory policy and practice

strategic market coverage in spatial competition abstract we consider in this paper competition through prices and market coverages in a spatial duopoly we characterize and compare the stackelberg equilibria and the bertrand equilibria we show that when the cost of informing the consumers is small duopolists always choose to inform all consumers in the bertrand equilibrium but the leader in the stackelberg equilibrium may choose not to inform everyone when the duopolistic competition is intense enough thereby generating overlapping markets in equilibrium prices may be strategic complements strategic substitutes or be strategically independent considering market coverage as chosen by the firms changes the conventional relationships between differentiation profits and markups

disneyland monopoly interlinkage and usurious interest rates abstract interlinkage between labour and credit markets is interpreted as a consequence of a monopolistic moneylender s attempt to extract consumer s surplus from the borrower by levying a two part tariff this analogy enables us to draw on the literature on non linear pricing to high light issues in agrarian structure the consequence of policy interventions like taxes and minimum wage legislation is studied it is shown that the moneylender will charge usurious interest rates if wages are rigid downwards or there is a tax on agricultural income or borrowers have heterogeneous preferences some geometry for analysing interlinkage is developed and used for deriving some of the results

credit and sharecropping in agrarian societies this paper considers a model of linkage between land labor and credit transactions in the context of sharecropping the paper s objectives are a to derive and characterize the equilibrium in a model of a land scarce labour abundant economy under sharecropping given an infinitely elastic supply of identical sharecroppers at a reservation utility and b to demonstrate that in an imperfect market a landlord may offer credit to his tenant sometimes even at a subsidized rate of interest without necessarily insisting that the sharecropper borrow only from him precluding an involuntary linkage between credit and land transations it has been demonstrated that regardless of the presence or absence of linkage or any other control by the landlord as long as he can vary the size of the plot given to a tenant and there are enough potential tenants in equilibrium contracts a tenants utility under sharecropping will be the same as that which he could have obtained as a full time wage laborer this result implies that policies other than land reform will not affect the welfare of tenants

customer poaching and advertising this paper is a first look at the dynamic effects of customer poaching in homogeneous product markets where firms need to invest in advertising to generate awareness when a firm is able to recognize customers with different purchasing histories it may send them targeted advertisements with different prices it is shown that only the firm which advertises the highest price in the first period will engage in price discrimination a practice that clearly benefits the discriminating firm this poaching gives rise to the race for discrimination effect through which price discrimination may act actually to soften price competition rather than intensify it as a result all firms may become better off even when only one of them can engage in price discrimination this paper offers a first attempt to evaluate the effects of price discrimination on the efficiency properties of advertising in markets with low or no advertising costs allowing firms to price discriminate leads them to provide too little advertising which is not good for consumers and overall welfare only in markets with high advertising costs might firms overadvertise regarding the welfare effects price discrimination is generally bad for welfare and consumer surplus though good for firms

the potential bias in producer service employment estimates the case of the canadian space economy footloose information technology producer services are increasingly viewed as the new engines of regional growth and employment creation the claim is often that appropriate government policy can engineer comparative advantage in that direction by means of judicious subsidisation the evaluation of such claims relies on accurate statistical data we argue that attempts to distinguish in survey data or official statistics the subset of services commonly but unofficially known as producer services from consumer and government services may result in a potential bias with implications for public policy an input output model is developed for estimating this bias by decomposing service industry data into its producer and consumer services content this method can give a truer estimate of the actual employment in producer services at various spatial levels we find a systematic bias in official data and a non systematic bias in survey data the model is applicable to countries and regions for which input ou

competitive promotional strategies this article analyzes the equilibrium pricing strategies of brands engaged in a pricing game each brand has a monopoly market loyal consumers and competes with others in a common market called brand switchers in the case of a duopoly it is shown that the behavior of the brand switchers characterizes the equilibrium behavior of the duopolists this article focuses on two key comparative statics namely the depth of discounts away from a regular high price and the probability of giving a deal or the frequency of deals how these properties vary with the size of the loyal markets and the behavior of the brand switching population is discussed copyright 1988 by the university of chicago

products liability and prescription drug prices in canada and the united states this article provides the first estimate of the degree to which product liability costs in this country contribute to the observed differences in pharmaceutical prices between the united states and canada measures of liability risk show up as large and strongly significant explanatory variables in regressions of u s and canadian price differences in the sample used here accounting for liability effects reduces the mean of the predicted price difference distribution by about one half and the median by about one third these reductions come about by virtually eliminating the upper tail of the distribution though liability effects cannot account for all the observed price differences in this sample they clearly must play a role efforts to explain international price differences in drug products which do not take account of the effects of differing legal systems are missing an important effect and suffer from a substantial omitted variable bias

fragmented duopoly a conceptual and empirical investigation where wireline distribution networks compete each network typically has some customers over which it competes and others for which it is the sole provider this paper conceptually and empirically assesses the effects of such competition on market prices demand and service quality for cable television service the results suggest that the effectiveness of competition in lowering prices is contingent on the degree of system overlap in particular in equilibrium an increase in overlap substantially reduces prices the conceptual model of fragmented duopoly developed in the paper may be useful in analyzing emerging competition in other network distribution industries

liability and large scale long term hazards this paper analyzes the application of liability to large scale long term hazards the key features distinguishing such hazards are the long temporal separation between exposure to a hazard and disease and the large damages when injuries finally emerge the large scale of damages creates a strong incentive to avoid liability payments and the long temporal separation creates numerous avenues through which parties can avoid paying possible damage awards the analysis focuses on the incentive to avoid paying damages by vertically divesting production tasks associated with serious occupational risks such divestiture can lower liability costs if the small firm operating the risky stage goes out of business before latent injuries emerge or has insufficient assets to pay damages and declares bankruptcy when suits are filed the paper then presents an empirical regression analysis of small firm entry into the u s economy between 1967 and 1980 the period in which liability laws were changing the point estima

cost effectiveness analysis and innovation while cost effectiveness ce analysis has provided a guide to allocating often scarce resources spent on medical technologies less emphasis has been placed on the effect of such criteria on the behavior of innovators who make health care technologies available in the first place a better understanding of the link between innovation and cost effectiveness analysis is particularly important given the large role of technological change in the growth in health care spending and the growing interest of explicit use of ce thresholds in leading technology adoption in several westernized countries we analyze ce analysis in a standard market context and stress that a technology s cost effectiveness is closely related to the consumer surplus it generates improved ce therefore often clashes with interventions to stimulate producer surplus such as patents we derive the inconsistency between technology adoption based on ce analysis and economic efficiency indeed static efficiency dynamic efficiency and improved patient health may all be induced by the cost effectiveness of the technology being at its worst level as producer appropriation of the social surplus of an innovation is central to the dynamic efficiency that should guide ce adoption criteria we exemplify how appropriation can be inferred from existing ce estimates for an illustrative sample of technologies considered we find that the median technology has an appropriation of about 15 to the extent that such incentives are deemed either too low or too high compared to dynamically efficient levels ce thresholds may be appropriately raised or lowered to improve dynamic efficiency

a model of price leadership based on consumer loyalty this paper analyzes a duopolistic price setting game in which firms have loyal consumer segments but cannot distinguish them from price sensitive consumers the authors adapt a variant of h varian s 1980 simultaneous price setting game to analyze price leader equilibria the properties of the price leader equilibria with an exogenously specified leader motivate the construction of a game of timing in which the firm with the larger segment of loyal consumers becomes an endogenous price leader this demonstrates that consumer loyalty may play an important role in establishing the existence and identity of a price leader copyright 1992 by blackwell publishing ltd

fragmented duopoly theory and applications to backward agriculture abstract the central aim of this paper is to provide a formal description of the idea of market fragmentation which is so widely used to describe markets in backward agriculture we begin by describing a fragmented duopoly in which each seller has a captive set of customers and there is a non captive set who may buy from either seller the nash cournot equilibria of the system are analyzed and then the model is generalized to allow for the endogenous determination of the captive sets the subgame perfect equilibrium of the model provides a useful background for studying familiar topics like fragmentation interlinkage and disguised unemployment from a new point of view

servitisation and value co production in the uk music industry an empirical study of consumer attitudes abstract since the rise of music on the internet the record industry has reported falling total sales revenues this has occurred at a time when technology has radically increased choice availability and the opportunity for the consumer to purchase music to date pay per unit music sales channels have been more successful than music subscription services as the music industry has moved from a product to a service business model does the loss of sales indicate they have not taken their customers with them this paper provides a description of different music consumer attitudes an independent variable in this research based upon quantitative analysis of more than 5000 valid survey responses consumer purchasing behaviour and music discovery methods are treated as dependant variables an empirical study using structural equations model was carried out to test the relationship between consumer groups and purchasing preference in relation to tangible products and intangible service purchases moreover consumer typology and propensity to actively engage with music communities was analysed and thus their willingness to co produce value was explored the most important findings were first all consumers view pay per unit positively and second a group of consumers representing just under half the sample was identified that would engage with a monthly subscription music service and could co produce solutions in this channel

changing rules in tort law and the market for childhood vaccines much attention has been focused on the changes in the legal environment that have swept this country in the past two or three decades one of the more important changes has been the movement toward strict products liability although this evolution has not been complete in many cases it has become much easier for injured consumers to obtain compensation from manufacturers the increased availability of compensation made possible by this evolution has been hailed as a great victory for consumer interests assailed for its economic inefficiency and blamed for increasing the costs and risks of engaging in business and thus causing a decline in the competitiveness of american industry 1 while there exists a well developed theoretical literature on the relative efficiency of alternative liability rules 2 little reliable evidence has yet been generated on the actual consequences of this evolution 3 it is to this issue that this article is addressed the evidence generated here comes from the market for childhood vaccines a market which is particularly

price competition and advertising in oligopoly abstract this paper studies price advertising in an oligopoly market where consumers have only local price information sellers may attract consumers from other locations by advertising their price with positive probability they advertise a low price to attract customers from distant locations with the remaining probability they post a high price and serve only local customers the random advertising equilibrium approaches the equilibrium under perfect price information when the cost of advertising becomes small

de targeting advertising an assortment of products to loss averse consumers we consider product markets in which consumers are interested only in a specific product category and initially do not know which product category matches their tastes using sophisticated tracking technologies an intermediary can make inferences about a consumer s preferred product category and offer advertising firms the possibility to target their ads to match the consumer s taste such targeting reduces overall advertising costs and as a direct effect increases industry profits however as we show in this paper when consumers form reference prices and are loss averse more precise targeting may intensify competition between firms as a result firms may earn higher profits from de targeted advertising i e when the intermediary deliberately informs about some products and their price quotes from outside a consumer s preferred product category

sharecropping and the interlinking of agrarian markets one of the often noted features of less developed agrarian economies is the existence of interlinkages among the land labor credit and product markets the landlord is often the supplier of credit he frequently purchases and markets the output of the tenant farmers and often sells raw materials and even consumption goods to his tenant farmers how can this phenomenon be explained what are the welfare consequences of attempts to restrict these practices which often seem to constitute restraints on free trade these are the questions to which this paper is addressed a general set of arguments applicable to both competitive and noncompetitive environments are presented to situations where all the terms of the contract are determined in an optimal way as well as to situations where many of the terms are specified institutionally section i examines interlinked credit and tenancy contracts section ii examines interlinked marketing and tenancy contracts section iii points out the possible interlinking between labor contracts and consumption goods markets and section iv presents the different equilibrium frameworks discussed in the paper such as monopoly monopsony competition and equilibria with surplus labor

is the food and drug administration safe and effective in the united states the food and drug administration fda provides public oversight of the safety and efficacy of drugs medical devices biologics like vaccines and blood products cosmetics radiation emitting electronic products veterinary products and all foods except meat and poultry which are regulated by the department of agriculture according to the fda the products it regulates account for more than one fifth of u s consumer spending in the area of medical products the fda is responsible for determining whether marketed products are both safe and effective before and after they have been marketed in this paper we will explore whether the policies of the agency itself are safe and effective we stress two issues one static and one dynamic the static issue concerns the potential duplication inefficiency when product safety is protected not only by the fda but also by the private sector through product liability law put another way what is the rationale for using product liability and the fda to regulate drug safety while intuitively it may seem that two systems must be better than one in ensuring drug safety each system comes with costs we then turn to the dynamic issue the speed safety trade off and consider the extent to which higher safety is achieved at a cost of later market entry of effective and even life saving products we assess the prescription drug user fee acts pdufas which increased the speed of the agency s regulatory process starting in 1992 although according to some at the cost of reducing drug safety we conclude by suggesting a research agenda for future work on the food and drug administration

segmentation advertising and prices this paper explores the implications of market segmentation on firm competitiveness in contrast to earlier work here market segmentation is minimal in the sense that it is based on consumer attributes that are completely unrelated to tastes we show that when the market is comprised by two consumer segments and when there is sufficient variation in the per consumer costs firms need to incur to access the different consumer populations then firms obtain positive profits in symmetric equilibrium otherwise the equilibrium is characterized by zero profits as a result a minimal form of market segmentation combined with advertising cost asymmetries across consumer segments give firms an opportunity to generate positive rents in an otherwise bertrand like environment

an inquiry into quasi credit contracts the role of reciprocal credit and interlinked deals in small scale fishing communities in agrarian village societies beset with many hazards and uncertainties people evolve various means of coping with risk what is perhaps less known is that credit transactions can sometimes serve the function of reducing risk in such societies this article is concerned with examining several insurance motivated credit arrangements in small scale fishing communities a hunger insurance mechanism of reciprocal credit and a system of interlinked contracts aimed at insuring against risks in the spheres of labour and marketing relations will be extensively dealt with moreover the concept of triadic relationships will be shown to have special relevance in the case of traditional insurance arrangements aiming at controlling problems of moral hazard

why are different services outsourced to different countries the tradability revolution in services has led to a dramatic expansion of offshore outsourcing of services allowing firms to take advantage of lower production costs in foreign countries however production costs alone cannot explain the location determinants of offshore outsourcing of services in this paper we argue that minimizing transaction costs is also an important determinant of the location of offshore outsourcing of services we empirically analyze characteristics of services and characteristics of foreign countries that may impact on transaction costs in an outsourcing relationship and hence determine where services will be outsourced offshore we derive measures of service characteristics routineness complexity and interactiveness based on the tasks required to provide them further we posit that there are interaction effects between service and country characteristics using bureau of economic analysis data on us service outsourcing across 11 types of services to 31 countries between 1992 and 2005 we find that 1 services that are more routine less complex or less interactive are outsourced more to foreign countries 2 services are outsourced more to countries with higher institutional quality and greater cultural proximity 3 non routine complex and interactive services are outsourced relatively more to countries with a better institutional quality
