an experimental examination of competitor based price matching guarantees we use experimental methods to demonstrate the anti competitive potential of price matching guarantees in both symmetric and asymmetric cost duopolies our findings establish that when costs are symmetric price matching guarantees significantly increase market prices in markets with cost asymmetries guaranteed prices remain high relative to prices without the use of guarantees but the overall ability of price guarantees to act as a collusion facilitating device becomes contingent on the relative cost difference lesser use of guarantees combined with lower average prices and slower convergence to the collusive level suggest that the mere presence of cost asymmetries may curtail collusive behavior

price discrimination through offers to match price in this paper a firm discriminates between two classes of customer who have a different cost of information by coupling a list price with an offer to match the pr ice of any other shop if the list price elsewhere is lower the firm will be successful in discrimination the list price of each firm is increasing in the number of sellers and the total sales are decreasi ng in the number of sellers furthermore if sellers coordinate they discriminate more efficaciously and increase their profits by increa sing their total sales copyright 1987 by the university of chicago

bureaucratic capacity delegation and political reform thecentraltensionmotivatingcontemporarytheories of delegation from politicians to bureaucrats lies in the potential conflict between the value of bureaucratic expertise on one hand and the desire for political control on the other this tension is well known and has been debated at least since weber s classic work on bureaucracy modern bureaucracies are staffed with individuals who by virtue of rational bureaucratic organization are highly skilled policy experts who in principle should be able to help less knowledgeable politicians achieve their goals however the very skills and expertise that bureaucrats enjoy create the possibility that bureaucrats will usurp the rightful role of politicians in policymaking processes because the way this tension is resolved determines the ultimate compatibility of democracy and bureaucracy existing theories of delegation typically focus on understanding how and to what extent politicians can resolve it 1 in many contexts particularly developing democracies bureaucracy does not fit the weberian characteristics that are assumed in the existing delegation literature the bureaucracies may be staffed with individuals who lack the personal capacity to execute orders effectively the organizational structure may lead to breakdowns within bureaucratic hierarchies making it difficult for senior administrators to control their subordinates departments and ministries may lack basic budgets and resources to undertake implementation actions they may suffer from incentives for

an experimental and theoretical analysis of price matching refund policies abstract price matching refund policies or offers by firms to match competitor s prices are common in both consumer and industrial marketing much of the previous theoretical work in economics suggests that price matching refunds are associated with higher prices in contrast the trade press postulates that price matching policies are associated with lower prices given these inconsistent views regarding price matching policies the authors experimentally examine how consumers view and interpret such policies and then develop a model that incorporates these consumer interpretations as well as asymmetries across stores in the model the asymmetry across stores is the key to deriving the conditions under which a signaling equilibrium exists in the presence of price matching policies the critical point is that the competition reducing and price discrimination effects which seem to form the basis of most of the previous theoretical literature can be counteracted by the presence of differentiated firms

do patents over compensate innovators is the current level of patent protection too high or too low to address this issue this paper reformulates the theoretical analysis of the optimal level of patent protection to take into account the empirical findings of the innovation production function literature this literature finds a strong relationship between r d spending and inventions and estimates an elasticity of the supply of inventions of 0 5 or more the paper then assesses the current level of patent protection exploiting estimates of the private and social returns to r d taken from the empirical literature and other available sources although more research is needed for a more precise assessment the evidence available suggests that patents do not over compensate innovators vincenzo denicolo

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

duplicative research mergers and innovation abstract we show that in the model of federico et al 2017 horizontal mergers may actually spur innovation by preventing duplication of r d efforts federico et al do not notice this result because they presume that the merged firm spreads its r d expenditure evenly across the research units of the merging firms a strategy which is optimal however only if the probability of failure is log convex in the rd effort the possibility that mergers spur innovation is more likely the greater is the value of innovations and the less rapidly diminishing are the returns to r d

on the competitive effects of price matching policies abstract this paper challenges the conventional wisdom that price matching policies lead to supracompetitive prices by reducing firms incentives to undercut rivals i argue that price matching and price beating policies are more appropriately viewed as a means of price discrimination and develop a model that demonstrates their use as such analysis of this model shows that in contrast to the results of the existing literature price matching and price beating may raise or lower equilibrium prices relative to the equilibrium in which firms may not adopt such policies

digital piracy a competitive analysis in recent years the issue of copyright protection for intellectual properties such as computer software music cds and videos has become increasingly important it is often claimed that illegal copying of intellectual property costs companies billions of dollars in lost revenues and reduces firms incentives to innovate some researchers have shown that copying can be beneficial to firms when there are strong network effects and copying expands the market in this paper we first examine the impact of illegal copying of software and other similar intellectual properties on firms prices profits and quality choices even when there are no network effects and the market is saturated we show that contrary to the claims of manufacturers there are conditions under which copying can increase firms profits lead to better quality products and increase social welfare this is because weaker copyright protection enables firms to reduce price competition by allowing price sensitive consumers to copy thus weaker copyright protection can serve as a coordination device to reduce price competition we also examine how equilibrium copyright enforcement is affected by network externalities in contrast to previous research we show that strong network effects can sometimes lead to a firm choosing higher levels of copyright protection our results show that in the presence of strong network effects stronger copyright enforcement by one firm can serve as a coordinating device to reduce price competition

separation of powers and the budget process abstract we study budget formation in a model featuring separation of powers in our model the legislature designs a budget bill that can include a cap on total spending and earmarked allocations to designated public projects each project provides random benefits to one of many interest groups the legislature can delegate spending decisions to an executive agency that can observe the productivity of all projects before choosing which to fund however the ruling coalition in the legislature and the executive serve different constituencies so their interests are not perfectly aligned we consider settings that differ in terms of the breadth and overlap in the constituencies of the two branches and associate these with the political systems and circumstances under which they most naturally arise earmarks are more likely to occur when the executive serves broad interests while a binding budget cap arises when the executive s constituency is more narrow than that of the powerful legislators

modeling asymmetric competition the effects of the marketing actions of one brand can be distributed among its competitors market shares in a complex manner this paper presents and illustrates methods for modeling brand competition and brand strategies in markets where competitive effects can be differentially and asymmetrically distributed we discuss the empirical specification parameter estimation and competitive strategy implications of the models proposed price and advertising competition among eleven brands of an australian household product is used to illustrate the application of these procedures

price matching guarantees are price matching guarantees anticompetitive we examine the incentives for price matching guarantees in markets where information about prices is costly the conventional explanation of price matching as facilitating cartel pricing finds some theoretical support but our model provides an additional explanation a price matching guarantee may be a credible and easily understood means of communicating to uninformed consumers that a firm is low priced the credibility of the signal is assured by the behavior of informed consumers we contrast the testable implications of our model with those arising from two theories of price matching as anticompetitive and show that available evidence supports the signalling theory

asymmetric information and legislative rules some amendments we reexamine the major tenets of the informational theory of legislative rules focusing on the informational efficiency of rules with varying degrees of restrictiveness when committees are heterogeneous full efficiency is attainable under the unrestrictive open rule as well as the somewhat restrictive modified rule in contrast the restrictive closed rule always leads to inefficiencies when committees are homogeneous the situation is different all equilibria are inefficient regardless of legislative rules but the closed rule leads to greater informational efficiency than does the open rule furthermore the efficiency gains under the closed rule more than offset distributional losses regardless of the degree of preference divergence we also examine the incentives provided by the different rules for information acquisition and committee specialization

policy specific information and informal agenda power in gilligan and krehbiel s models of procedural choice in legislatures a committee exerts costly effort to acquire private information about an unknown state of the world subsequent work on expertise delegation and lobbying has largely followed this approach in contrast we develop a model of information as policy valence we use our model to analyze a procedural choice game focusing on the effect of transferability i e the extent to which information acquired to implement one policy option can be used to implement a different policy option we find that when information is transferable as in gilligan and krehbiel s models closed rules can induce committee specialization however when information is policy specific open rules are actually superior for inducing specialization the reason for this surprising result is that a committee lacking formal agenda power has a greater incentive to exercise informal agenda power by exerting costly effort to generate high valence legislation

optimal asymmetric strategies in research joint ventures abstract this paper identifies an overlooked implication of models of research joint ventures initiated by d aspremont and jacquemin 1988 even though the aggregate r d cost of identical firms in a research joint venture would be lowest if they invested equally to reduce subsequent production costs nonetheless members may often enlarge their overall joint profit by making unequal investments such a strategy raises costs in the investment stage but may create more than offsetting benefits in the production stage since industry profits are larger there when the firms are of unequal size when the consideration leading to asymmetry prevails we find that in contrast to previous work a research joint venture can raise welfare even when there are no spillovers

price match announcements in a consumer search duopoly using a model of sequential search we show that announcements to price match raise prices by altering consumer search behavior first price matching diminishes firms incentives to lower prices to attract consumers who have no search costs second for consumers with positive search costs price matching lowers the marginal benefit of search inducing them to accept higher prices finally price matching can lead to asymmetric equilibria where one firm runs fewer sales and both firms tend to offer smaller discounts than in a symmetric equilibrium price increases grow in the proportion of consumers who invoke price matching guarantees and in the level of equilibrium asymmetry

innovation and industry evolution the theoretical literature on innovation has been concerned with a single innovation produced by a number of identical agents by contrast we consider a market in which one firm is the current incumbent while the remaining firms are challengers moreover we consider a sequence of innovations so that success does not imply that the successful firm reaps monopoly profits forever after but only until the next better innovation is developed we begin with a fully optimizing behavioral model and derive the equivalent of the schumpeterian process of creative destruction that is a firm enjoys temporary monopoly power but is soon overthrown by a more inventive challenger the essential point to grasp is that in dealing with capitalism we are dealing with an evolutionary process the fundamental impulse that sets and keeps the capitalist engine in motion comes from the new consumers goods the new methods of production or transportation the new markets the new forms of industrial organization that capitalist enterprise creates schumpeter 1942 pp 82 83

contingent pricing to reduce price risks the price for a product may be set too low causing the seller to leave money on the table or too high driving away potential buyers contingent pricing can be useful in mitigating these problems in contingent pricing arrangements price is contingent on whether the seller succeeds in obtaining a higher price within a specified period we show that if the probability of obtaining the high price is not too high sellers profit from using contingent pricing while economic efficiency increases the optimal contingent pricing structure depends on the buyer s risk attitude a deep discount is most profitable if buyers are risk prone a consolation reward is most profitable if buyers are risk averse to motivate buyers to participate in a contingent pricing arrangement the seller must provide sufficient incentives consequently buyers also benefit from contingent pricing in addition because the buyers with the highest willingness to pay get the product contingent pricing increases the efficiency of resource allocation

mergers of complements and entry in innovative industries abstract i study a merger between producers of complement inputs facing potential entry with investment by the incumbents in deterministic cost reduction and by the entrants in probabilistic innovation and then competition in prices the merger solves cournot complementarity problems in investment and pricing which is what makes it profitable but also potentially anti competitive when the demand is inelastic the merger harms consumers by reducing r d of the entrants if the incumbents are efficient enough always when bundling is adopted instead with a demand elastic enough the merger increases consumer surplus even with bundling

capital as a commitment strategic investment to deter mobility abstract this paper analyzes how an early entrant in a market can exploit its head start by strategic investment the analysis is based on spence s paper investment strategy and growth in a new market bell j econ 10 1979 1 19 we frist study the investment game in the no discounting case which embodies the key features of mobility deterrence we establish the existence of a set of perfect equilibria and suggest that one particular equilibrium is most reasonable this equilibrium also valid with discounting involves the follower firm being forever deterred from investing to its steady state reaction curve in contrast to spence s proposed solution

coordination economies advertising and search behavior in retail markets we introduce a model of the retail firm in which consumers and active firms benefit collectively from coordination of sales at fewer firms using this model we show that ostensibly uninformative advertising plays a key role in bringing about coordination economies by directing consumer search toward firms that offer the best deals optimal consumer search takes the form of a simple rule of thumb that uses observed advertising information to guide search both industry concentration and social surplus are higher in the presence of advertising relative to a no advertising benchmark jel d83 l15 many observed advertisements seem to be at odds with rational behavior in a variety of ads mostly on tv and radio multiproduct sellers provide little hard information choosing instead to impart only vague slogans that are suggestive of good deals examples are plentiful a hardware store

gridlock and delegation in a changing world fixed statutes and regulations often have variable consequences over time if left unattended such drift can severely erode the performance of government as an institution of representation to better understand the mechanics of policy making in a changing world we develop a positive theory that captures political drift in a dynamic separation of powers system we show analytically that a distinctive combination of legislative supermajoritarianism and agency discretion institutional features that in isolation elicit widespread criticism can effectively ameliorate policies susceptibility to the vicissitudes of exogenous change the critical mechanism for governmental accommodation of drift is delegation which increases all decision makers well being by reducing fluctuations in outcomes although the complete smoothing of outcomes is attainable in a separation of powers system we show that this is typically not achieved in equilibrium the presence of drift provides an opportunity for self interested legislators to extract a distributional benefit from their fellow legislators at the expense of overall policymaking efficiency

oligopolistic pricing with sequential consumer search n identical stores compete by choosing prices for a homogeneous good with constant marginal costs consumers search sequentially with perfect recall for the lowest price one class of consumers called shoppers have zero search costs while all other consumers have a positive search cost c there is a unique symmetric nash equilibrium price distribution with the property that it changes smoothly from marginal cost pricing when all consumers are shoppers and or c 0 and monopoly pricing when no consumers are shoppers remarkably as the number of stores increases the nash equilibrium becomes more monopolistic copyright 1989 by american economic association

how much discretion for risk regulators we analyze the regulation of firms that undertake socially risky activities but can reduce the probability of an accident inflicted on third parties by carrying out non verifiable effort congress delegates regulation to an agency although these two bodies may have different preferences toward the industry the optimal level of discretion left to the agency results from the following trade off the agency can tailor discretionary policies to its expert knowledge about potential harm but it implements policies that are too pro industry the agency should be given full discretion when the firm is solvent partial discretion is preferred otherwise we then investigate how this trade off changes as the political and economic landscapes are modified

competitive price matching guarantees equilibrium analysis of the availability verification clause under demand uncertainty price matching guarantees involve a retailer matching the lower price of a competitor for an identical product in reality retailers often make such guarantees contingent on the verification of product availability at the competitor s location and decline a price match request if the product is not available there this creates certain consternation on the part of customers in this paper we investigate the availability contingency strategy from the perspectives of both the retailers and the customers our analysis shows that availability contingency clauses intensify inventory competition between retailers and reinstitutes price competition which is otherwise eliminated by unconditional price matching guarantees consequently despite what customers may think about the availability verification it actually increases their surplus on the other hand such a clause reduces profits and hence is not the equilibrium strategy for retailers subsequently we discuss how a likely customer behaviour pattern may be a plausible explanation regarding the use of the clause by the retailers in practice this paper was accepted by yossi aviv operations management

incumbent performance and electoral control in the pure theory of electoral competition citizens compare the platforms of the candidates and vote for the one whose platform is preferred candidate strategies are identified with promises about future performance in office models of this sort have been developed in both static mckelvey 1975 and dynamic kramer 1977 i settings and all appear to have the property that if the set of alternatives is large enough in some sense equilibrium platforms rarely exist but these models have another feature that is quite as disturbing as their instability in the static setting discussed by mckelvey little attention is paid to the possibility that once in office the politician s preferences may diverge from those of his constituents and that he may therefore choose policies at variance from his platform instead it is simply assumed that promises will be kept whether or not such behavior is congruent with the interest of the officeholder it is sometimes argued that an enforcement mechanism may exist to discipline politicians for failing to keep promises but without a specification of the mechanism it is not obvious that it would be in the interests of the

are moderates better representatives than extremists a theory of indirect representation few if any elected representatives are capable of unilaterally implementing their platforms rather they choose between options generated by other actors and or external events we present a theory of voters preferences over representatives who will cast votes on their behalf and show that in this setting voters preferences over candidates platforms will not look like voters preferences over policies we demonstrate that these induced preferences for representation tend to favor more extreme representatives and we present two models of electoral competition in which induced preferences over representatives lead to elite polarization

on the use of low price guarantees to discourage price cutting abstract this paper formulates a novel test to assess whether and to what extent firms might be using low price guarantees to discourage their rivals from cutting prices the test is based on a comparison of paired observations of advertised prices that are set by competing firms at the same point in time on similar items where one price is set by a firm that has a low price guarantee and the other by a firm that does not have a low price guarantee using data on retail tire prices we find that the majority of paired observations involving firms that have price matching guarantees are consistent with what one would expect if firms were using them to discourage price cutting whereas the majority of paired observations involving firms that have price beating guarantees are not this suggests that price matching and price beating guarantees may be serving different purposes the evidence also suggests that guarantees that apply to advertised prices only may be serving different purposes than guarantees that apply to both advertised and selling prices

modeling the psychology of consumer and firm behavior with behavioral economics abstract marketing is an applied science that tries to explain and influence how firms and consumers behave in markets marketing models are usually applications of standard economic theories which rely on strong assumptions of rationality of consumers and firms behavioral economics explores the implications of the limits of rationality with the goal of making economic theories more plausible by explaining and predicting behavior more accurately while maintaining formal power this article reviews six behavioral economics models that are useful to marketing three models generalize standard preference structures to allow for sensitivity to reference points and loss aversion social preferences toward outcomes of others and preference for instant gratification the other three models generalize the concept of game theoretic equilibrium allowing decision makers to make mistakes encounter limits on the depth of strategic thinking and equilibrate by learning from feedback the authors also discuss a sp

experimental duopolies under price guarantees in a symmetric differentiated experimental duopoly we test the ability of price guarantees pgs to raise prices above the competitive levels different types of pgs aggressive and soft price beating and price matching are implemented either as an exogenously imposed market rule or as a business strategy our results show that pgs may lead close to the collusive outcome depending on whether the interaction between duopolists is repeated and provided that the guarantee is not of the aggressive price beating type

price matching guarantees as a direct signal of low prices if consumers believe that stores offering price matching guarantees pmgs charge low prices high search cost consumers will purchase from pmg stores this leads pmg stores demand to be less pric

a model of duopoly and meeting or beating competition this paper analyzes the use of meeting and beating competition clauses in duopoly markets a differentiated products price setting model is considered in which firms have the option of precommitting themselves to contracts which bind their own price to be some prespecified function of their competitor s price the analysis establishes conditions under which these contracts facilitate oligopoly coordination under which they result in price discrimination and under which they can actually be procompetitive

spatial models of delegation canonical assumptions this approach may be justified on grounds of tractability but the failure to grasp the significance of different assumptions and push beyond specific models has limited our understanding of the incentives for delegation consequently the justifications for delegation that have received recent scrutiny and testing differ from some of the more plausible justifications offered by informal studies of delegation we show that surprisingly few results in the literature hinge on risk aversion and surprisingly many turn on the ignored though equally canonical technological assumption that uncertainty is fixed relative to policies relaxing the key assumptions about dimensionality and functional forms provides a clearer intuition about delegation one that is closer to classical treatments the theory allows us to relate different institutional features commitment specialization costs monitoring multiple principals to delegation s observable properties lthough the practice of delegation dates back to antiquity the book of exodus refers to itonly in the last century has much scholarship examined its causes and effects and only recently has research focused on developing and testing formal theories that explore the logic of delegation 1 despite this recent surge in formal work on delegation scholars have failed to generalize several important properties of the early pathbreaking models instead of revisiting assumptions that were initially imposed for the sake of convenience recent papers tend to maintain and reinforce the cannonical assumptions applying these limited models to ever richer institutional settings although the breadth of understanding about delegation across various settings is impressive this approach has come at a price it has produced an understanding that only partly captures delegation s informational rationale in even the simplest contexts the literature is rich in predictions about delegation in complicated institutional settings when stylized foundational assumptions are satisfied but poor in explanations for and intuitions about why a poorly informed boss chooses to delegate to subordinates with different preferences moreover we lack an understanding of what basic features drive the boss s choice of which agent is given control of policy for example scholars have provided detailed explanations about how separation of power systems affect delegation by legislatures to agencies but the basic question does the informational rationale for delegation hinge on the boss s risk preferences has been ignored despite the analysis of complicated signaling and screening games between bosses with ex post controls and their subordinates we do not yet understand when or why the ally principle the boss picks the most ideologically similar agent as delegatee fails in simple settings we try to put models of delegation on more solid footing by examining a larger more general set of environments we eschew the canonical assumptions of quadratic utility or even risk aversion unidimensional outcome spaces and additive and homogeneous random shocks to policy our analysis focuses first on two basic questions when does delegation occur and to whom does the boss delegate we then consider richer institutionally driven extensions e g the role of commitment and monitoring devices the impact of multiple bosses and the institution in which their preferences are aggregated through a sequence of nested models with varying levels of abstraction the analysis isolates the relations between various assumptions and different findings

research note price matching guarantees retail competition and product line assortment price matching guarantees pmgs are offers to match a competitor s price on a specific item such guarantees are extremely common in u s retail practice and their impact has been studied in several published papers the existing analytic literature models each retailer as a single product seller most work assumes that each retailer s product is identical with or completely substitutable for the competitor s product in reality competing retailers often sell multiple products and these products do not always overlap or may overlap partially but not totally furthermore retailers that offer pmgs routinely exclude certain offerings from pmg coverage this raises the interesting question of how product variety and product stocking factors affect retailer decisions about offering pmgs in this paper we simultaneously consider three factors of retailing importance that imply results consistent with pmg use and nonuse the ability to choose to stock the same product as or a product differentiated from a competitor s offering the possibility of shelf space limitations on the ability to stock complete variety and the category demand enhancing effect of variety these are sensible and realistic descriptive factors shaping retailers product and pricing decisions and because they have not been considered jointly in the prior literature on pmgs their joint consideration helps to expand our understanding of the drivers of pmg implementation and impact in the presence of these three factors we examine retailers decisions about whether to offer a pmg what product s to stock and how to price the product s stocked our results show that shelf space limitations have an important influence on pmg provision in particular when retailers are shelf space constrained and product substitutability in the category is sufficiently large choosing to use pmgs which by definition also requires stocking identical products is strictly less profitable than enduring bertrand price competition but enjoying retail product differentiation the result that pmgs can be profit reducing relative to head to head retail competition is a novel one driven in our model by the opportunity costs of stocking identical products i e the inability to benefit from the demand enhancing effects of variety and the differential small or large between bertrand pricing and pmg pricing levels we further show that under asymmetric shelf space availability either product variety will be severely limited or retailers will offer a different array of products weak substitution between products leads to the latter with pricing between the differentiated products bertrand and monopoly levels strong substitution leads to the former with pricing at the monopoly level our results also show that with unlimited shelf space both competing retailers offer pmgs stock the entire available product line and enjoy monopoly pricing given our focus on product variety issues we also relate our results to the literature on branded variants our results demonstrate that the nature of product variety the availability of retail shelf space and the category demand enhancing effect of variety are key market characteristics that jointly and strongly affect the optimality of pmgs and the resulting pricing and profitability characteristics of the market

preemption and rent equalization in the adoption of new technology we study the adoption of a new technology to illustrate the effects of preemption in games of timing we show that the threat of preemption equalizes rents in a duopoly but that this result does not extend to the general oligopoly game if the gain to preemption is sufficiently small then the optimal symmetric outcome which involves late adoption is an equilibrium this contrasts with reinganum s result that in precommitment equilibria there must be diffusion we develop a new and richer formalism for modeling games of timing which permits a continuoustime representation of the limit of discrete time mixed strategy equilibria

a consumer perspective on price matching refund policies effect on price perceptions and search behavior although price matching refund policies are common in many retail environments the impact of such policies on consumers has largely been ignored this article reports the results of three studies that examine price matching policies from a consumer perspective study 1 shows that consumers perceive price matching policies as signals of low store prices and that the presence of a refund increases the likelihood of discontinuing price search contrary to the predictions based on signaling theory in information economics studies 2 and 3 show that when search costs are low the number of stores searched increases in the presence versus absence of a price matching policy when search costs are high consumers appear to accept the price matching signal at face value and search less in the presence of a refund the article concludes by discussing the theoretical implications of the findings and suggesting directions for future research

research note consumer heterogeneity and competitive price matching guarantees price matching guarantees are widely used in consumer and industrial markets previous studies argue that they are a marketing tactic that facilitates implicit price collusion this is because once a store adopts this marketing tactic its rivals can no longer steal its customers by undercutting its price and hence they have little incentive to initiate price cuts while a store with price matching guarantees has no fear of losing customers to rivals price cuts it has every incentive to raise its own price to charge a higher price to its loyal consumers a growing body of legal literature uses this argument today to justify calls for antitrust actions against stores employing this marketing tactic however this theoretical conclusion baffles practitioners and industry experts in practice sellers typically embrace this marketing tactic in response to heavier competition and a growing bargain consciousness among shoppers the introduction of price matching guarantees by a store is frequently interpreted by industry observers as the initiation of a price war rather than a signal of price collusion this assertion is supported in many instances by the fact that stores that introduce price matching guarantees also roll back their prices and typically suffer subsequent loss of profits most ironically the favorite examples used by researchers to illustrate how price matching guarantees can enforce price collusion crazy eddie and nobody beats the wiz have subsequently either gone bankrupt or filed for federal bankruptcy protection in this study we show that price matching guarantees can indeed facilitate competition the expected prices and profits can be strictly lower when all stores adopt price matching guarantees than when they are not allowed to this is because the adoption of price matching guarantees generates not only a competition dampening effect which has been recognized in the literature but also a competition enhancing effect this latter effect comes from the fact that price matching guarantees encourage price search by those consumers who prefer to shop at a particular store but are mindful of saving opportunities these consumers will have incentives to obtain the rival store s price when their favorite store offers price matching guarantees to avail themselves of the lowest possible price at their favorite store as a result price matching guarantees reduce the number of purchases at the store from those consumers who would have paid the full price and thus prompt a store to price more aggressively to bid for more incremental sales this competition enhancing effect can more than offset the competition dampening effect in markets where consumers differ in their price search costs and store loyalty thus our study casts doubt on the advisability of blanket prohibition on price matching guarantees our argument relies only on consumer segmentation and on the phenomenon of periodic sales both of which are common in retail markets we arrive at our conclusion by incorporating bargain shoppers and opportunistic loyals into the standard sales promotion models in contrast the past literature on price matching guarantees ignores the ubiquitous phenomenon of sales in retail markets and overlooks those consumers who prefer to shop at a particular store but are alert to saving opportunities as a result it is troubled by two awkward conclusions on the one hand price matching guarantees simply remove rivals incentives to undercut in price and hence also their incentives to run sales this implies that the adoption of price matching guarantees in a market will eliminate the phenomenon of sales which is obviously counterfactual on the other hand in equilibrium no consumer actually invokes price matching guarantees as each player has incentives to close any price gap in the market this is obviously false based on our casual observations and our conversations with store managers theoretical research on the subject thus far has been overwhelmingly one sided and empirical or experimental studies are conspicuously lacking we hope that our conclusion will spark further research in both directions a healthy debate will broaden our perspective on an issue of great importance in formulating public policies and in managerial decision making
