the value priority hypotheses for consumer budget plans based on the behavioral sciences and mathematical programming we hypothesize that consumers rank durables by a value or net value priority approximated by utility per dollar or utility minus price and plan to choose items in that order up to a budget cutoff this paper derives these hypotheses and develops a convergent linear programming procedure to estimate utility using primary field data on reservation prices purchase probabilities lottery orders and combination prizes we estimate utilities and compare the hypotheses to 215 actual budget plans lisrel v analysis provides further support for the hypotheses

product and price competition in a duopoly this paper examines the role of consumer preferences costs and price competition in determining the competitive product strategy of a firm in the model studied here there are two identical firms competing on product quality and price they face consumers who prefer a higher quality product to a lower quality product but differ in how much they are willing to pay for quality the consumers can also choose a substitute if they don t like the product price offerings of the two firms for the firms a higher quality product costs more to produce than a lower quality product the paper shows that the equilibrium strategy for each firm should be to differentiate its product from its competitor with the firm choosing the higher quality choosing the higher margin as well this differentiation however is not efficient that is it is possible to choose two other products and offer them at prices that cover their marginal cost and still satisfy consumers needs better in the aggregate a monopolist by contrast would differentiate his product line efficiently this suggests that cannibalization has different effects on product strategy than competition the paper also shows that if one firm enters the market first then it can defend itself from later entrants and gain a first mover advantage by preempting the most desirable product position

information provision in a vertically differentiated competitive marketplace this paper examines the interaction of information provision product quality and pricing decisions by competitive firms to explore the following question in a competitive market where consumers face uncertainty about product quality and or their preference for quality which firms those that sell higher or lower quality products have the higher incentive to provide what type of information we find that while the higher quality firm should always provide information resolving consumer uncertainty on product quality the lower quality firm under certain conditions will have the higher incentive to and will be the one to provide information resolving consumer uncertainty about their quality preferences in the analysis we trace the latter result to competition and to free riding on the information provision specifically in a monopoly market or when consumer free riding is restricted by the costliness of store visits the lower quality firm would have a lower incentive to provide information resolving consumer preference uncertainty than otherwise the model is also adapted to examine product returns as a possible strategy of information provision

on the effects of downstream entry we study the effects of entry in a downstream market where firms e g compaq and ibm cvs and safeway buy an input e g microprocessor grocery items from an upstream supplier e g intel procter gamble and sell their output to consumers we show demand conditions where contrary to conventional wisdom entry of a new downstream firm lowers the downstream market output and increases the consumer price thus consumers may be better off with fewer sellers in such markets we also show that this entry may cause the profit of each incumbent downstream firm to i remain unchanged ii decrease or iii even increase also for a class of widely used demand conditions the supplier s optimal price is shown invariant to the entry exit of its downstream buyer firms we classify all possible effects of downstream entry in terms of fundamental market demand conditions

competitive pricing by a price leader we examine the problem of pricing in a market where one brand acts as a price leader we develop a procedure to estimate a leader s price rule which is optimal given a sales target objective and allows for the inclusion of demand forecasts we illustrate our estimation procedure by calibrating this optimal price rule for both the leader and the follower using data on past sales and prices from the mid size sedan segment of the u s automobile market our results suggest that a leader follower system stackelberg seems more consistent with the pricing behavior in this market than a mutually independent pricing rule nash we also find that our optimal price rule explains this market data better than other pricing schemes that do not account for optimizing behavior on the part of the leader and the follower

chapter 4 competitive marketing strategies game theoretic models publisher summary this chapter reviews the key developments in the understanding of competitive marketing strategies product price advertising and distribution competition are all addressed while the emphasis is on models the chapter surveys the empirical literature as well there is a significant amount of empirical work to report but the ratio of theoretical to empirical work is nevertheless unpleasantly large much progress has been made in the last ten years or so in the study of competitive marketing strategies most of this chapter has been theoretical using simple models of firm and consumer behavior these models serve the function of demonstrating rigorously the existence of certain effects factors which need to be considered in analyzing real world competition

changing comparative advantage and the changing composition of asian exports apid economic growth in several asian economies particularly those from east and southeast asia and subsequently in china and south asia has led to rapid structural transformation in these economies if one takes a historical perspective it was in accordance with what kuznets 1966 and chenery and syrquin 1975 posited in a growing economy the decline of the agricultural sector has generally been accompanied by strong expansion of the manufacturing and or services sector transforming economic structure has had a direct bearing on the trade structure of the economy looking back three decades one finds that in several asian economies the structural transformation has been more or less fundamental pari passu these economies have experienced a dynamic process of changing comparative advantage this entailed a rapid growth in their exports of manufactures as well as a changing structure of manufactured exports in what follows we will evaluate the process of transformation of economic structures and changes in the manufacturing sector in the asian economies followed by changes in comparative advantage resulting in higher product sophistication of exports with the passage of time

sophisticated entry in a model of spatial competition we analyze free entry equilibrium in a model of spatial competition in which locations of established firms are fixed and entrants profit expectations are rational our most interesting results concern large economies economies in which the number of firms is arbitrarily large when the average cost function is u shaped free entry equilibrium is unique socially optimal and characterized by zero profit in contract when there are no diseconomies of scale even large economies are stubbornly imperfect firms can earn substantial pure profit and free entry equilibrium is neither unique nor socially optimal

technical note existence and uniqueness of price equilibria in defender this note provides a formal proof that for the defender model with uniformly distributed tastes the nash price equilibria exist and for a given set of positions that they are unique we also show that the profit function is well behaved continuous and quasi concave and that the maximum occurs on the concave portion of the curve

the government financial system and large private enterprises in the economic development of south korea abstract the paper investigates the main characteristics of the government business relationship in south korea in the past three decades to find out how it may have contributed to south korea s economic development it proposes that the government and large private enterprises in south korea should be viewed as constituting an internal organization namely a quasi internal organization as such extensive intervention by the government with south korea s financial system can be viewed as an internal capital market and consequently it could have led to a more efficient allocation of credit than possible in a free market financial system it also argues that the quasi internal organization has made it possible for the government to efficiently implement its developmental policies it is however pointed out that for the quasi internal organization to be successful in accelerating the pace of economic development the country must have a political leadership committed to the goal of economic development and must adopt an outward oriented development policy

competitive strategies for late entry into a market with a dominant brand this paper considers optimal positioning advertising and pricing strategies for a firm contemplating entry in a market dominated by an entrenched competitor drawing on behavioral research on consumer preference formation we develop an individual level model that reflects differing consumer responses to similar products offered by the dominant brand and later entrants an effect we term asymmetric preferences from the resulting aggregate market response model we derive several competitive implications notably 1 that preference asymmetry can make a differentiated late entry strategy optimal even if preferences would appear to dictate otherwise and 2 that me too strategies are not equilibrium late entry strategies more generally our analysis suggests that preference asymmetry can contribute to the persistent competitive advantage of dominant brands

facilitating fit revelation in the competitive market this study examines firms strategic decisions in the competitive market regarding whether to engage in marketing activities to assist consumers in finding the fit between their personal tastes and products horizontal attributes we find that competitive firms strategies to facilitate fit revelation critically depend on the product qualities they offer in particular a firm offering a high quality product is more likely to facilitate fit revelation in the competitive market than it would as a market monopolist whereas a firm offering a low quality product is less likely to do so in addition the firm offering the high quality product implements fit revealing activities in a greater intensity than its rival that offers the low quality product if the quality difference between the two products is small and both products qualities are sufficiently high

the principle of minimum differentiation holds under sufficient heterogeneity the so called principle of minimum differentiation stated by hotelling has been challenged by many authors this paper restores the principle by showing that n firms locate at the center of the market and charge prices higher than the marginal cost of production when heterogeneity in consumers tastes is large enough

price matching policy and the principle of minimum differentiation this paper shows that if duopolists are allowed to choose their product locations a price matching policy and their prices sequentially and independently both tacit collusion and minimum differentiation occur copyright 1995 by blackwell publishing ltd

alternative models of spatial competition the concept of a spatial price equilibrium underlies most studies of spatial movement and competition however this concept is based upon a notion of perfectly competitive markets that is often unrealistic for many markets such as the markets for oil and coal and ignores the existence of local spatial monopolies this paper presents alternative economic models of spatial competition and shows how all of these models can be solved with essentially the same solution algorithm specifically after reformulating the classical spatial price equilibrium model and two extensions of takayama and judge s monopoly model we state and analyze a cournot nash model and discuss solution algorithms we then generalize these models and algorithms to multiple commodities and networks with transshipment nodes we conclude with a brief discussion of possible extensions of this class of models and associated algorithms

the structure of equilibria in market share attraction models a market share attraction model of competitive effort allocation by two firms is formulated as a constant sum two person game the dependence of optimal competitive effort allocations on factors such as gross profit margins relative effectiveness of effort and attraction elasticity of effort is studied two versions of the model are developed in the first version effort budgets of both competitors are exogenously fixed in the second the competitors each choose both budget levels and allocations in each version of the model an important function of the parameters called the competitive advantage ratio indicates when it is optimal to either increase or decrease effort allocated in a market in response to changes in various measures of effectiveness implications of differences in the cost associated with each competitor s budget on equilibrium allocations are derived

profit maximizing perceptual positions an integrated theory for the selection of product features and price an important component of marketing strategy is to position a product in perceptual space but to realize a perceptual position we must model the link from physical characteristics to perceptual dimensions and we must use this model to maximize profit this paper integrates psychological theories on how consumers process information with economic models and psychometric measurement and it develops a theory for selecting physical features and price to achieve a profit maximizing perceptual position the theory begins with a lancaster like transformation from goods space to characteristics space and investigates the implications of a mapping to a third space perceptual space we show that all products efficient in perceptual space must be efficient in characteristics space but not conversely but consumers vary in their preference and the way they perceive products thus we introduce distributional components to the theory and derive both geometric and analytic methods to incorporate this consumer heterogeneity next we investigate costs and derive a perceptual expansion path along which a profit maximizing position must exist conjoint analysis and quantal choice models provide the measurements to implement the theory the theory is illustrated with a hypothetical example from the analgesics market and some of the potential psychometric measurements are illustrated with an empirical application in the communications market

the choice theory approach to market research this paper surveys economic choice theory stressing developments that permit use of data from psychometric and conjoint experiments to produce market demand forecasts alternatives to the widely used multinomial logit model are summarized and a new method for estimating multinomial probits is described an integration of choice models with attitudinal scaling and perceptual mapping within a latent variable system is described estimation of such systems under either random effects or fixed effects descriptions of heterogeneity across individuals is discussed issues in the use of choice models to describe responses from conjoint experiments are presented new regression diagnostic tests for the consistency of multinomial logit representations are discussed

on hotelling s competition with non uniform customer distributions abstract hotelling s competition in a two stage location price game is examined with increasing densities of consumers towards the centre it is shown that there is a range of rather even distributions for which firms locate at opposite ends of the market as the distribution becomes more concentrated duopolists will tend to move inside the market

defensive marketing strategies this paper analyzes how a firm should adjust its marketing expenditures and its price to defend its position in an existing market from attack by a competitive new product our focus is to provide usable managerial recommendations on the strategy of response in particular we show that if products can be represented by their position in a multiattribute space consumers are heterogeneous and maximize utility and awareness advertising and distribution can be summarized by response functions then for the profit maximizing firm it is optimal to decrease awareness advertising it is optimal to decrease the distribution budget unless the new product can be kept out of the market a price increase may be optimal and even under the optimal strategy profits decrease as a result of the competitive new product furthermore if the consumer tastes are uniformly distributed across the spectrum a price decrease increases defensive profits it is optimal at the margin to improve product quality in the direction of the defending product s strength and it is optimal at the margin to reposition by advertising in the same direction in addition we provide practical procedures to estimate 1 the distribution of consumer tastes and 2 the position of the new product in perceptual space from sales data and knowledge of the percent of consumers who are aware of the new product and find it available competitive diagnostics such as the angle of attack are introduced to help the defending manager this article was originally published in marketing science volume 2 issue 4 pages 319 360 in 1983

sequential product positioning under differential costs this paper examines the product positioning decisions of firms that enter a market sequentially and that have potentially different cost structures it shows that if the first mover knows the second mover to have a lower production cost it positions away from the most attractive location in the market further the larger the second mover s cost advantage the farther away the first mover positions from the most attractive location the paper also models uncertainty in the first mover s mind about the later entrant s cost structure and shows that an increase in this uncertainty in the sense of mean preserving spread also makes the first mover position farther from the most attractive location in the market overall this paper suggests that unless the first entrant in a market is certain that the later entrant will not have a superior cost structure it may be better off leaving the best position in the market vacant and having a niche or fringe product

deconstructing the pioneer s advantage examining vintage effects and consumer valuations of quality and variety several studies have demonstrated an order of entry effect on market share suggesting that pioneers outperform later entrants however other research has pointed out the limitations of these studies and found evidence that many pioneers fail or have low market share given this background the purpose of this research is to understand the conditions under which pioneers are more likely and also less likely to have an advantage we propose a game theoretic model that includes important sources of pioneer advantages as well as disadvantages specifically we incorporate a pioneer advantage due to preemption in markets with heterogeneous tastes in addition we incorporate a potential pioneer disadvantage due to technology vintage effects where later entrants utilizing improved technology can have lower costs and higher quality the model allows us to evaluate the extent of vintage effects necessary to overcome a pioneer s advantage key relationships are found between the magnitude of the pioneer advantage or disadvantage and consumer valuations of product attributes e g variety and quality we empirically validate the model with vintage effect data in 36 product categories and measures of consumer valuations of product variety and quality for 12 of these 36 categories the results show that pioneers do better in product categories wherevariety is more important and worse in categories where productquality is more important pioneers in categories with high vintage effects are shown to have lower market shares and higher failure rates similar results appear when analyzing persistence of market leadership over time further validating our model s major implications we also present two case studies that illustrate key elements of the model

an equilibrium analysis of defensive response to entry using a coupled response function model we determine the optimal response to competitive entry in a market characterized by a market share attraction model the response of an incumbent is limited to changes in prices advertising and distribution expenditures brand positions are assumed to be fixed we also assume that the entrant s position is chosen exogenously and that the sales potential of the market is constant after proving the existence of a unique nash equilibrium we show that the optimal response depends on the relative market share of the incumbents the response by nondominant brands with market shares less than 50 mirrors the prediction by decoupled response function models reduce price advertising and distribution spending for the dominant brand having a market share of 50 the response is to reduce price and increase marketing spending this finding explains previous empirical results that could not be addressed by the decoupled models

modeling competitive pricing and market share anatomy of a decision support system even with today s high emphasis on management decision support systems relatively little has been published on the motivations tribulations and post mortems that generally accompany the development of such systems this paper reports in a mixture of narrative style and more formal model exposition how a computerized decision support system for optimal price determination was developed implemented and finally applied to a broad range of industry problems

the principle of minimum differentiation revisited abstract hotelling s model of differentiated products is examined and modified so that consumers have relatively low reservation prices for the differentiated products the problem of existence of a nash equilibrium in prices in a duopoly with given products is analysed when the reservation price is relatively low a nash equilibrium in prices exists for a larger range of products than when the reservation price is infinite next i examine product competition with instantaneous adjustment to the nash equilibrium prices of the previous game firms competing in a nash fashion have tendencies to move away from each other and try to achieve local monopolistic positions this is in sharp contrast with the acclaimed principle of minimum differentiation of the original model of hotelling of high reservation price where firms clustered in the product space

hotelling s spatial competition as a model of sales abstract hotelling s spatial competition model is used to explain the existence of sales it is shown that 1 an equilibrium in randomized strategies exists when a pure strategy equilibrium fails to exist 2 with more dissimilarity among brands prices are chosen from a wider interval

spatial price and variety competition in an urban retail market abstract we develop a nested logit model of spatial competition in retail markets consumers choose stores on the basis of price variety and transport cost three games are considered a price game a variety game and a combined price and variety game the videocassette rental market in edmonton alberta is used for illustration centrally located stores set lower prices and higher varieties than stores on the market periphery prices in the price and price variety games are nearly identical despite large differences in varieties similarly equilibrium varieties in the price variety game are similar to varieties in the variety game

note competitive price and positioning strategies brand positioning and brand pricing are important strategic decisions for marketing managers such decisions are interrelated and depend upon competitive brand positions and prices however any unilateral decisions may encourage repositioning and price adjustment by competitors thus leading to either new market equilibria or a price positioning war this paper examines such price and positioning decisions in a competitive environment by extending the defender consumer model to more complex equilibria we assume that the brands are already in the market and that positions are sticky in the sense that brands cannot leapfrog one another among the insights for such incumbent brands are if prices are symmetric and held constant firms seek to reposition toward the center of the market but price advantages by central firms can mediate that central tendency such that an equilibrium exists with positive profits if brand positions are held constant the nash equilibria for prices exist and are unique and category profits the sum of brand profits are maximized for maximum brand differentiation for two and three brand markets the subgame perfect nash equilibrium where positioning decisions are made with foresight on the price equilibria causes firms to unilaterally seek maximum brand differentiation but for four or more brands greater foresight and or cooperation appears necessary to reach the point of maximum brand differentiation these results apply where the defender consumer model is an exact description of consumer response and where the competitive reaction assumptions hold in any empirical situation such forces might be softened resulting in differentiated but not maximally differentiated brands

a comparative analysis of the use of information inputs in the manufacturing sectors of korea and japan abstract the paper examines the use of two information inputs information labor and purchased information services in korean and japanese manufacturing sectors in 1980 marginal products and substitution elasticities are calculated from translog production function estimates for the average manufacturing sector both inputs seem to be relatively more underused in korea second the elasticity estimates suggest several hypotheses about the growth of private bureaucracies in the two economies the results are unlikely to apply to other economies which have not yet attained an advanced industrial structure a simplistic stages theory of economic development based on the growth of the information labor force is rejected

pricing strategies in a dynamic duopoly a differential game model we formulate a differential game model for dynamic pricing in a duopolistic market firms demand functions are derived from utility maximizing behavior of consumers with the demand for a brand given by the logit model preferences for brands are assumed to evolve over time in the market in a manner akin to learning models postulated in the marketing literature we derive the differential equations governing the equilibrium open loop price paths over time and show that in steady state the brand with the higher preference level charges the higher price the formulation is extended to include the effects of consumer heterogeneity and equilibrium steady state prices are compared with those obtained when heterogeneity is ignored a comparison of steady state dynamic prices with myopic prices is provided an empirical example is discussed to show how steady state model predictions may be obtained from actual longitudinal purchase data

product and price competition in a two dimensional vertical differentiation model in this paper the one dimensional vertical differentiation model shaked and sutton shaked a j sutton 1982 relaxing price competition through product differentiation rev econom stud 49 3 13 moorthy moorthy k s 1988 product and price competition in a duopoly marketing sci 7spring 141 168 is extended to two dimensions and an analysis of product and price competition is presented a two stage game theoretic analysis in which two firms compete first on product positions and then on price is conducted closed form equilibrium solutions are obtained for each stage in which competitors are unrestricted in their choices of price or product positions a significant finding of this research is that unlike the one dimensional vertical differentiation model firms do not tend towards maximum differentiation although this solution is possible under certain conditions when the range of positioning options on each of the dimensions is equal maxmin product differentiation occurs that is in equilibrium the two firms tend to choose positions which will represent maximum differentiation on one dimension and minimum differentiation on the other dimension

valuing environmental resources under alternative management regimes abstract this paper shows that the economic values of resources depend in part on the management regime the value of a resource supporting a commercial fishery will depend on whether the fishery is optimally managed or open access the ellis fisher 1987 data are used to calculate values under alternative assumptions about management these calculations show that value is influenced not only by biological and economic factors but also by institutions

marketing production decisions in an industrial channel of distribution this paper presents a model that considers the interface between marketing and production decisions in a channel of distribution of industrial goods comprised of a manufacturer and a distributor the key issue investigated is the nature of the coordination within the channel in light of an unstable pattern of seasonal demand the investigation which focuses on dynamic issues considers production activities such as product delivery and inventory policy and their link to marketing strategies such as pricing policies the focus here is on the dynamic nature of the coordinational aspects of the various policies for example the following questions are addressed what is the distributor s pricing strategy throughout the season what is the nature of the contractual price in the channel under what conditions should the distributor carry no inventory throughout the seasonal period under what conditions should the manufacturer carry no inventory what is the impact of the seasonal parameters and differing h

trade as the engine of growth in developing countries revisited economic growth in developed countries since the mid 1970s the only way to keep the engine of ldc growth beating at a satisfactory rate so the argument goes is to turn to an alternative source of fuel this lewis argues lies in trade among the developing countries which he asserts can take up the slack left by mdcs more developed countries as mdcs slow down 1980 p 560 pessimism about demand for ldc exports in developed countries markets is a recurrent theme in the development literature also familiar is the approach taken by lewis to dismiss past successes of ldcs in world trade by declaring the alleged engine of past growth to be no longer operating satisfactorily the intellectual foundations of the import substitution strategy laid in the 1950s by prebisch myrdal and most importantly nurkse rested on similar grounds arguing that the demand for periphery countries exports in the 20th century is far weaker than it was in the 19th century trade was dismissed as an engine of growth a function nurkse alleged it had served in the 19th century the solution prescribed in the 1950s was to look inward in effect to scrap the trade engine altogether lewis remedy coming two decades later when most importsubstitution possibilities in many ldcs have been all but exhausted retains the trade engine but seeks an alternative source of fuel to drive it the classic critique by irving kravis 1970 of nurkse s thesis of trade as a faltering engine of growth showed that export expansion did not serve in the nineteenth century to differentiate successful from unsuccessful countries p 850 this followed from two findings first that successful 19th century countries showed few signs of export dominated growth second that unsuccessful periphery countries enjoyed export expansion in the second half of the 19th century of the same order of magnitude as the temperate regions of recent settlement this led kravis to conclude that a more warranted metaphor

the economic valuation of saltwater marsh supporting marine recreational fishing in the southeastern united states abstract this paper is concerned with placing an economic value on the contribution of wetlands in supporting recreational fishing in the southeastern united states a production function first links the recreational catch to angler fishing effort and wetlands the parameters of the recreational fisheries production function are estimated using cross sectional data by states to simplify the mathematics the estimated elasticities are substituted into a cobb douglas production function for simplicity a linear demand curve for recreational fishing is postulated which shifts when there is an increase or decrease in the catch success rate therefore incremental changes in wetlands will via the production function provide incremental changes in the catch which will in turn shift the recreational demand curve thereby increasing or decreasing consumer surplus using a discount rate of 8 125 the perpetual flow of consumer surplus per incremental acre of wetlands has an estimated asset value of 6 471 and 981 on the east and west coast of florida respectively in 1984 dollars if commercial fisheries and other economically useful functions of wetlands are added to recreational fisheries it may be more efficient for the state of florida to acquire more coastal land for preservation from development

determining the appropriate depth and breadth of a firm s product portfolio abstract some firms have broad product lines others have lean product lines to determine the appropriate number of entries in a specific firm s product line the author develops a model that balances the benefits of increased revenue from a broad product line against production and engineering costs two innovations were central in the development of the model 1 redefining how products are scored on various product attributes so that attribute scores vary normally across the population of products and 2 redefining how the number of entries in a product portfolio is calculated in order to discount the significance of entries that are highly similar to existing products the author also introduces the notion of a centroid time to more easily adjust sales and total development costs for product life cycle and investment life cycle effects these redefinitions enable a firm s profit to be modeled as a simple function of its effective number of product entries the effective number of competitors entrie

product positioning and competition the role of location in the fast food industry this paper examines optimal product positioning strategies of asymmetric firms in the context of retail outlet locations in the fast food industry the relationships between profits and product differentiation reveal that both mcdonald s and burger king are better off avoiding close competition if the market area is large enough however in small market areas mcdonald s would prefer to be located together with burger king rather than have the two outlets be only a slight distance apart in contrast burger king s profits always increase with greater differentiation offsetting these incentives is the desirability of locating centrally to appeal to the most customers the equilibrium depends on the market s size in small markets mcdonald s locates near the center of the market and burger king locates to the side of the market in larger markets mcdonald s and burger king choose locations on opposite sides of the market although mcdonald s locates closer to the optimal central location than burger king i also show that the role of price competition on product positioning is fundamentally different under asymmetric competition than under symmetric competition price competition unambiguously induces symmetric firms toward differentiation in contrast with asymmetric firms price competition shifts burger king s incentives toward locating closer to mcdonald s even while price competition increases mcdonald s desire for differentiation as a result equilibrium locations with asymmetric firms are approximately the same regardless of whether prices adjust with location

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

the importance of focus to market entrants abstract one of the most difficult questions facing entrepreneurs is how broadly to serve a heterogeneous market that is whether it is better to serve a narrow segment of the market hoping to flourish by gaining a relatively high and increasing market share within that segment or whether it is better to attempt to appeal to a broader cross section of the market thereby allowing the firm to succeed with a lower market share among the customers whom it is targeting a narrower focus permits more concentrated use of fixed resources facilitates the building of customer loyalty and lowers the threat of retaliation from generalist incumbents but requires a much higher market share within the firms target market to succeed porter 1980 has identified three generic strategies available to firms low cost differentiation and focus by focus he means that the firm should develop the ability to serve a particular target customer group very well often at the expense of other potential customer groups implicit in the firm s choice to adopt a focus strategy is that it must address the question of how broadly to focus in terms of any given product attribute given its resources and opportunities a fundamental element of the firm s choice of focus is that it is affected by and in turn affects that of its rivals that is focus is a strategic variable in the sense of the word strategic meant by game theorists each firm s optimal choice of action depends on the actions taken by other firms the literature on the optimal degree of focus for new ventures has reached very mixed conclusions the early authors looking at the question were fairly consistent in their recommendation that a highly focused or niche strategy was generally most appropriate later authors recommended that new ventures should enter markets aggressively facing larger incumbents head on the latest studies develop what we describe as a contingency approach arguing that the best approach depends on industry conditions we think that this literature is now at a point where we can advance our understanding by looking at specific industries in some detail as our understanding expands broader empirical work is becoming increasingly difficult because of the number of factors that must be built into any cross sectional model of new venture performance we hope then to develop an understanding of one industry that is generally similar in nature to many other industries from this understanding conclusions of interest to both researchers and practitioners can be drawn future studies of other industries with different fundamental structures will provide similar benefits more specifically this paper is an empirical inquiry into the microbrewery segment of the u s brewing industry designed to investigate the relative merits of specialist firms different degrees of focus the question addressed is whether focus affects specialist firms short run performance in an industry where there are entrenched generalists as well as many new entrpreneurial specialist entrants the analysis confirms several widely held beliefs of industry participants and observers that microbreweries are far more likely to attempt to serve too broad a market segment than to focus too narrowly that microbreweries are in direct competition with imports and that microbreweries benefit from having many microbrewery rivals within the same state furthermore there appear to be some small learning and or reputation effects in the operation of microbreweries as well as a minor novelty factor that benefits recently opened establishments we must note however that the majority of the variation in the performance of microbreweries stems from differences in the management organization or market of individual breweries not captured explicitly by other variables included in the study this finding perhaps should not be surprising given the huge variation in the backgrounds skills and outlooks of microbrewery owners during the segment s early days the lessons learned from this research are of obvious importance to entrepreneurs in many industries it is a very common situation for an entrepreneur to enter a stable industry in which established firms are already in place serving a broad cross section of the market our findings show that in such circumstances a narrowly focused approach to the market is best we can think of numerous examples of where entrepreneurs have either succeeded by focussing on a particular segment of the market or failed by not doing so in fact there are many cases in which firms have done first one and then the other for example and people express airlines at first flourished by focussing on the needs of budget conscious leisure travellers and then collapsed in part because it began to try to serve business travelers and others who are less price sensitive on certain routes one of the hallmarks of an entrepreneurial business is that it suffers severe resource constraints because the entrepreneur s choice of breadth of focus will have profound effects on the resource requirements of the business it is clear that the choice of which segment or segments of the market on which to focus is a fundamental decision made by all entrepreneurs this paper serves to illustrate the importance of this focus decision and to provide some guidance for entrepreneurs concerning the appropriate degree of focus to adopt in entering an established market

structural adjustment policies in developing economies this paper examines structural adjustment policies in ldcs defined as policy responses to external or internal shocks that are carried out with the objective of regaining the pre shock growth path the introductory section of the paper reports on policy experience that indicates that countries applying an outward oriented development strategy were better able to cope with external shocks than economies following an inward oriented strategy it is further shown that the adoption of realistic exchange rates and interest rates the avoidance of large budget deficits and the productive use of the proceeds of foreign borrowing eased the process of adjustment the paper examines in detail the elements of a policy package that may be applied in response to external or internal shocks in the case prevalent in developing economies when optimal policies are not applied thus the recommendations simultaneously aim at responding to shocks and undertaking incentives incentives to save and to invest the choice of public investments sectoral policies in energy and agriculture budgetary policies and monetary policies in the conclusions the interdependence of the various policy measures is indicated with further attention given to foreign borrowing

the impact of competitive entry in a developing market upon dynamic pricing strategies this paper analyzes dynamic pricing strategies for new durable goods in a two period context the first period is characterized as a monopoly market structure for a new product having dynamic demand the second period begins when a new firm enters the market and thereby changes the market structure to a duopolistic one we begin by analyzing the pricing strategies of three types of monopolists nonmyopic myopic and surprised a nonmyopic monopolist is a first entrant who perfectly predicts the competitive entry a myopic monopolist totally discounts the duopolistic period and a surprised monopolist is a first entrant who has the longer time horizon of the nonmyopic monopolist but who does not foresee the competitive entry our results indicate that the nature of these pricing strategies may be quite different it is optimal for the nonmyopic firm to price its product at a higher level than the myopic monopolist additional results indicate under what circumstances the surprised monopolist will p

is having more channels really better a model of competition among commercial television broadcasters competitive behavior in commercial television broadcasting is modeled to examine program choice and the effects of more channels being available on firm strategy specifically broadcasters compete by selecting both the type and quality level of a program to offer but do not compete on price we obtain five major results first a comparison of monopoly and duopoly markets indicates that broadcasters in an industry with a larger number of competitors may provide programs of lower quality compared to broadcasters in an industry with a smaller number second in terms of viewer welfare having more channels available is not necessarily better third broadcasters tend to choose an intermediate level of differentiation in terms of the types of programs they provide resulting in a counterprogramming strategy in other words avoidance of price competition is not required for competitors to differentiate themselves from each other fourth if one broadcaster starts the evening with a higher quality higher rated program than its competitor its second program should also be of higher quality finally a broadcaster s first program should be of equal or higher quality than its second program put another way it always behooves a broadcaster to lead with its best

minimal and maximal product differentiation in hotelling s duopoly abstract hotelling s 1929 model of duopolistic competition is re examined a family of utility functions is used which has as a special case hotelling s original utility function in a two stage location price game it is shown that an equilibrium exists when the curvature of the utility functions in the space of characteristics is sufficiently high the subgame perfect equilibrium never exhibits minimum product differentiation on the other hand not all equilibria are at maximal product differentiation

valuing the environment as input review of applications to mangrove fishery linkages the following paper reviews recent developments in the methodology for valuing the role of wetlands in supporting economic activity the main focus will be on mangroves serving as a breeding ground and nursery habitat in support of coastal and marine fisheries as this particular ecological function of a mangrove system means that it is effectively an unpriced environmental input into fisheries then it is possible to value this contribution through applying the production function approach the first half of the paper overviews the procedure for valuing the environment as an input applied to the case of a wetland supporting a fishery both the static ellis fisher freeman approach and the dynamic approach developed by barbier and strand incorporating the intertemporal bioeconomic fishing problem are reviewed the second half of the paper discusses briefly two recent case studies of mangrove fishery valuation an application in south thailand which is based on the static ellis fisher freeman model and an application in campeche mexico which is based on the dynamic approach 2000 elsevier science b v all rights reserved

a dynamic approach to pes pricing and finance for interlinked ecosystem services watershed conservation and groundwater management a theory of payment for ecosystem services pes pricing consistent with dynamic efficiency and sustainable income requires optimized shadow prices since ecosystem services are generally interdependent this requires joint optimization across multiple resource stocks we develop such a theory in the context of watershed conservation and groundwater extraction the optimal program can be implemented with a decentralized system of ecosystem payments to private watershed landowners financed by efficiency prices of groundwater set by a public utility the theory is extended to cases where land is publicly owned conservation instruments exhibit non convexities on private land or the size of a conservation project is exogenous in these cases conservation investment can be financed from benefit taxation of groundwater consumers while volumetric conservation surcharges induce inefficient water use a dynamic lump sum tax finances investment without distorting incentives since the optimal level of conservation is generated as long as payments are correct at the margin any surplus can be returned to consumers through appropriate block pricing the present value gain in consumer surplus generated by the conservation induced reduction in groundwater scarcity serves as a lower bound to the benefits of conservation without explicit measurement of other benefits such as recreation biodiversity and cultural values

stackelberg nash cournot equilibria characterizations and computations the supply side of an oligopolistic market supplying a homogeneous product noncooperatively is modeled in this market there is one leader and n followers the followers operate under the cournot assumption of zero conjectural variation and are accordingly called cournot firms the leader called a stackelberg firm specifically takes into account the reaction of the cournot firms to its output for this situation we study the behavior and implications of the joint cournot reaction curve as generated by plausible economic market assumptions in particular we study the existence and uniqueness of a stackelberg nash cournot equilibrium in addition we prescribe an efficient algorithm to determine a set of equilibrating output quantities for the firms

defensive marketing strategies an equilibrium analysis based on decoupled response function models the entry of a new product attacker into a competitive market is likely to provoke responses from some or all of the existing products defenders this paper investigates the development of optimal defensive strategies based on an understanding of the possible reactions of all the defenders to an optimal attack following lane lane w j 1980 product differentiation in a market with endogenous sequential entry bell j econom 11 1 spring 237 260 we assume that n products each enter sequentially with perfect foresight on subsequent entry then based on new technology an unanticipated attacker enters the n defenders respond in price but not position according to lane s model once this equilibrium is obtained advertising and distribution response functions scale sales we show that under these decoupled response function models of advertising and distribution uniformly distributed tastes and nonincreasing market size the optimal defense for all existing brands is to decrease their respecti

trade and structural change nics and next tier nics as transitional economies abstract the paper finds a strong association between rapid change in the sectoral composition of output and exports structural change and rapid export growth in the newly industrializing countries capital formation appears to be encouraged in dynamic economies by the underpricing of investment goods vis a vis consumption and government goods within these economies also the underpricing of investment goods in dynamic economies is relatively greater than in less dynamic economies whereas other research has found low price distortion to be associated with high growth and an outward rather than an inward looking orientation these associations are seriously challenged and more caution is urged in reaching generalized conclusions

competitive positioning in markets with nonuniform preferences we investigate the nature of competitive equilibrium for brands competing in a multi attribute product space when consumer preferences for product attributes follow nonuniform distributions we establish subgame perfect equilibria in a two stage game where firms choose positions in the first stage and prices in the second stage two types of entry scenarios are investigated in the first the number of brands is given exogenously and all of them choose positions simultaneously in the second scenario firms enter in sequence and the early entrants can choose strategies to deter the entry of later entrants we find the equilibria for two three and four brands for consumer preferences that follow a beta distribution nonuniform distributions result in equilibrium configurations that are substantially different from those obtained for uniform consumer distributions in the two brands case for sufficiently concentrated distributions we find asymmetric position equilibria with one firm at the corner of the market and one firm at an interior position in the case of three brands for sufficiently concentrated preferences we find symmetric equilibria that do not yield maximal differentiation we also establish an equilibrium for the case of four competing brands in addition we characterize entry deterring positioning strategies and examine how they vary with the distribution of consumer preferences

models a la lancaster and a la hotelling when they are the same abstract consumer behaviour in differentiated product markets can be specified following the lancastrian characteristics approach or following hotelling s approach of spatial competition in the case of unit demand i present a class of models of heterogeneous consumer behaviour which can be written as models a la lancaster as well as models a la hotelling

depletion of the environmental basis for renewable resources the economics of interdependent renewable and nonrenewable resources abstract this paper synthesizes familiar theories of nonrenewable and renewable resource economics in a two sector partial equilibrium analysis of efficient trade offs between renewable resource production and environmental development the irreversible impacts of coastal zone development provide a motivating example while development proceeds the efficient harvest of renewable resources may exceed the sustainable rate while development may involve several periods of growth and decline once development begins it proceeds without significant interruptions if a profitable renewable sector survives development ceases before exhausting all profitable opportunities interdependent stocks reduce distinctions between resource types because each sector exhibits features of the other

product positioning under price competition this paper presents a consumer based methodology for new product pricing and positioning in the face of price competition the price competition is modelled as a nash equilibrium for which two complementary approaches are employed an analytical approach of duopoly provides qualitative insights into the competitive behavior and a numerical approach of general oligopoly provides quantitative solutions under a wide variety of market scenarios the optimal product positioning is formulated as a stackelberg nash leader followers equilibrium which can be solved numerically using recent advances in the field of variational inequalities a small example concerning analgesics is used to illustrate this methodology

strategic implications of market share attraction models market share attraction models which specify that a firm s market share is equal to the ratio of its attraction to the total attraction for all firms have received increasing attention in recent years however there has been little research investigating the practical implications of such models this paper presents a game theoretic analysis of such a model and deduces the strategic implications of a nash equilibrium solution to the model it is shown that these implications are consistent with previous empirical research in marketing and business policy

notes a numerical approach to deriving long run equilibrium solutions in spatial positioning models choi desarbo and harker 1990 have recently proposed a numerical methodology for optimal product positioning and pricing under the assumption that the incumbents react only with price changes in the short run the current note extends this methodology to include incumbents long run strategy of competitive product repositioning in addition to price reactions this note also introduces the notion of product relocation cost to the equilibrium analysis and applies the concept of full and partial adjustment processes toward an equilibrium to model various strategic behavior of firms this methodology is illustrated using an existing set of data collected for a major telecommunication equipment manufacturer

product differences and prices abstract under assumptions following hotelling s 1929 paper stability in competition the possibility of constructing an example in which equilibrium prices exist everywhere and the two merchants display tendencies to agglomerate is ruled out

an econometric model of location and pricing in the gasoline market abstract the authors propose an econometric model of both the geographic locations of gasoline retailers in singapore and price competition among retailers conditional on their geographic locations although market demand for gasoline is not observed the authors are able to infer the effects of such demand from stations locations and pricing decisions using available data on local market level demographics using the proposed location model which is based on the assumption of social welfare maximization by a policy planner the authors find that local potential gasoline demand depends positively on the local demographic characteristics of the neighborhood using the proposed pricing model which is based on the assumption of bertrand competition between retail chains the authors find that retail margins for gasoline are approximately 21 the authors also find that consumers are willing to travel up to a mile for a savings of 03 per liter using the estimates of the proposed econometric model the a

pricing patterns as outcomes of product positions prior empirical work shows that different markets are characterized by different pricing patterns such as bertrand nash pricing or stackelberg leader follower pricing the author considers a duopolistic market where ex ante identical firms sequentially position their products prior to competing on prices in a single or multiperiod setting and show that the unique equilibrium outcome involves 1 firms choosing stackelberg pricing over bertrand nash pricing and 2 the positioning first mover acting as the price leader an attractive property of this model is that the ex post larger firm acts as the price leader which is consistent with prior empirical evidence copyright 1999 by university of chicago press

hotelling s competition with general customer distributions abstract hotelling and his critics assumed uniformly distributed demand in this note the solution is characterized for any distribution f and some propositions follow for any f an equilibrium does not exist if the duopolists are located too closely together but another distribution can be always found for which an equilibrium does exist when we observe duopolies in equilibrium with closer and closer proximity we can expect the density in the area of contention to go up and prices and profits to go down hotelling s known suggestion that any duopolist has an advantage to move his location towards the other and thus creating a tendency for the differentiation to diminish holds whenever an equilibrium exists

perceptual position and competitive brand strategy in a two dimensional two brand market brand positioning and competitive reaction are important determinants of optimal brand strategy analyses of brand strategy have focused on optimal pricing and positioning issues using either empirical models of perceptions and preferences game theory to examine competition or both however the important issues of advertising and distribution strategy have not been fully addressed this paper analyzes competition and strategy between two brands that compete in a two dimensional market with advertising and distribution spending in addition to prices and product positions in particular for a unimodal taste distribution of ideal points we show how optimal competitive nash equilibrium marketing mix levels and profits depend on the positions of both brands brands can reposition to increase profit and under what conditions these strategies imply minimum versus maximum differentiation positioning equilibria and how the intensity of advertising and distribution competition affect equilibrium brand positions

nash equilibrium in duopoly with products defined by two characteristics this article analyzes the analogue ofhotellingls duopoly model when products are dejned by two characteristics using the assumptions of the original model of hotelling we show that demand and projt functions are continuous for a wide class of utility functions when the utilityfunction is linear in the euclidean distance in the space of characteristics a noncooperative equilibrium in prices exists for all symmetric locations ofjirms this is in contrast to the result in the one characteristic model where a noncooperative equilibrium exists only when products are very diferent the noncooperative equilibria are calculated and fully characterized in contrast with the one dimensional model of hotelling where equilibrium prices were constant irrespective of distance of symmetric locations here equilibrium prices tend to zero as the distance between products approaches zero

competition strategy and price dynamics a theoretical and empirical investigation the authors explore how competition affects dynamic pricing of new products dynamics of diffusion saturation and cost reduction due to experience are all considered with emphasis on the last t

aggregation and imperfect competition on the existence of equilibrium we present a new approach to the theory of imperfect competition and apply it to study price competition among differentiated products the central result provides general conditions under which there exists a pure strategy price equilibrium for any number of firms producing any set of products this includes products with multi dimen sional attributes in addition to the proof of existence we provide conditions for uniqueness our analysis covers location models the characteristics approach and probabilistic choice together in a unified framework to prove existence we employ aggregation theorems due to prekopa 1971 and borell 1975 our companion paper caplin and nalebuff 1991 introduces these theorems and develops the application to super majority voting rules we present a new approach to the theory of imperfect competition and apply it to study price competition among differentiated products the central result is that there exists a pure strategy price equilibrium for any number of firms producing any set of products in addition to the proof of existence we provide conditions for uniqueness our model both unites diverse strands of the earlier literature and opens up uncharted areas for future analysis in particular we expand the traditional one dimensional framework to allow for multi dimen sional product differentiation our approach involves twin restrictions on consumer preferences one on individuals preferences the other on the distribution of preferences across society these are generalizations of the restrictions supporting 64 majority rule presented in caplin and nalebuff 1988 to prove existence we apply a new technique of aggregation this technique is valuable in a variety of other problems in the companion paper we use the aggregation result to generalize our earlier work on 64 majority rule and to characterize the relationship between the distribution of human capital and the distribution of income caplin and nalebuff 1991 there are additional applications in statistics and in search theory we begin with a brief review of the early literature on imperfect competition describing in more detail the existence problem and previous solutions section 3 presents our twin assumptions and shows that they cover many standard cases in section 4 we introduce the aggregation theorem and use it in the analysis of demand functions the proof of existence of equilibrium is in section

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

new brand positioning and pricing in an oligopolistic market the positioning and pricing of a new brand requires knowledge about the relationship of both demand and cost with potential attribute locations and prices this paper addresses this problem and illustrates it in the context of the automobile market multi attribute expected utility theory which allows for consumer uncertainty about the brands is used to model individuals behavior attribute weights are estimated from market survey data on brands attributes and preferences using linmap as an estimation procedure expected utility is then updated using the multinomial logit model and choice data to account for the observation that stated preferences do not perfectly reflect the eventual choice it is hypothesized that when faced with an actual choice price may become more important to the consumer while other attributes may become more or less important than is reflected in stated preferences the resulting estimated choice probabilities are aggregated to form demand functions facing each brand which depend on all brands prices and attribute space locations assuming there is a price equilibrium in the existing market and that firms have the same variable cost function variable costs as a function of a brand s attribute levels are estimated given the demand and cost functions facing each firm including the potential new entrant the profit maximizing positioning and pricing of a new brand is analyzed using a game theoretic approach a solution is sought under the assumption that incumbents react to entry by changing their prices possible approaches to the translation of the perceptual attribute positioning of the new brand to physical and engineering attributes are reviewed improvements and future extensions of the study are discussed

explaining the dynamics of the southeast asian political economy state society and the search for economic growth this essay reviews two sets of books that explore the origins and dynamics of southeast asia s growth and economic transformation one set of books utilizes a structuralist framework and emphasizes the role of the state in creating a now powerful capitalist class the other set of books utilizes an institutionalist framework to explain how new patterns of private public sector collaboration have resulted in rapid economic growth the authors point to weaknesses in both approaches and to areas where the two approaches can be fruitfully synthesized they also offer suggestions for future research
