a characterization of erratic dynamics in the overlapping generations model abstract in this paper we characterize and give examples o wide classes of utility functions which generate erratic dynamics in the standard deterministic overlapping generations model erratic dynamics refers to feasible trajectories which are bounded but which do not converge to stationary points or periodic orbits we show that such trajectories are pareto efficient we introduce credit into the model and show how a constant credit expansion rate can result in erratic trajectories in prices and the real value of credit finally we briefly discuss certain technical aspects of the mathematics used and the statistical nature of the dynamics that can arise from deterministic dynamical systems

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

the role of market forces in assuring contractual performance the conditions under which transactors can use the market repeat purchase mechanism of contract enforcement are examined increased price is shown to be a means of assuring contractual performance a necessary and sufficient condition for performance is the existence of price sufficiently above salvageable production costs so that the nonperforming firm loses a discounted steam of rents on future sales which is greater than the wealth increase from nonperformance this will generally imply a market price greater than the perfectly competitive price and rationalize investments in firm specific assets advertising investments thereby become a positive indicator of likely performance

guaranteed lowest prices do they facilitate collusion abstract the effects of a policy guaranteeing lowest price are analyzed in a two stage game where firms first decide whether to adopt such a policy and then choose prices symmetric and asymmetric games are solved to examine the extent to which prices can rise to collusive levels

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

the organization of work a historical dimension abstract an evaluation of the organizational efficiencies of various modes of production by o e williamson has led him to conclude that given identical technologies the factory was more efficient than the putting out system the superior organizational efficiency of the former he maintains was one reason for the transition to factory production during the nineteenth century this paper challenges that view it is argued that the way in which williamson evaluates efficiency is open to methodological and other objections and that there is limited empirical support for his hypothesis given an identical technology the evidence suggests that the putting out system was usually able to compete with the factory

are commodity prices chaotic evidence from futures markets we conduct tests for the presence of low dimensional chaotic structure in the futures prices of four important agricultural commodities though there is strong evidence of non linear dependence the evidence suggests that there is no long lasting chaotic structure the dimension estimates for the commodity futures series are generally much higher than would be for low dimension chaotic series our test results indicate that autoregressive conditional heteroskedasticity arch type processes with controls for seasonality and contract maturity effects explain much of the non linearity in the data we make a case that employing seasonally adjusted price series is important in obtaining robust results via some of the existing tests for chaotic structure finally maximum likelihood methodologies that are robust to the non linear dynamics lend strong support to the samuelson hypothesis of maturity effects in futures price changes 2002 elsevier science b v all rights reserved

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

most favored customer pricing product variety and welfare abstract most favored customer mfc clauses are usually seen as anticompetitive co ordination devices that firms adopt for the purpose of higher prices here i examine the welfare impact of mfc clauses under endogenous product variety product variety is relevant because prospective higher prices from mfc clauses can be anticipated by multi product firms in their provision of product lines under such circumstances i find that these clauses can be socially harmful but this is not always the case they tend to be socially neutral for relatively large fixed costs of product line assortment harmful for intermediate costs and beneficial for relatively small costs

the function of authority in transaction cost economics abstract this paper questions the transaction cost characterization of observed authority relations as efficient governance structures various inadequacies in the transaction cost account of work organization and the limits of firm size are traced to its neglect of the possibility that authority may be abused opportunistically this exemplifies a more general propensity in the transaction cost literature that of explaining economic organization in functionalist terms with little attention to the causal mechanisms through which efficient governance structures might actually arise three such mechanisms are considered but none is found to provide an adequate rationale for the imputation of efficiency to observed structures

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

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

on the incidence and variety of low price guarantees abstract this paper provides evidence of the incidence and variety of low price guarantees promises to match or beat a rival s price using data obtained from newspaper advertisements in 37 metropolitan areas in the united states we have a total of 515 low price guarantees in our sample we document their features and we infer firms motives and effects from these features the evidence suggests that the majority of low price guarantees are not consistent with their use as a facilitating device because they tend to apply only to rival firms advertised prices or they are associated with high hassle costs the evidence also suggests that price beating and price matching guarantees differ significantly in their features the former are associated with higher hassle costs apply disproportionately to rival firms advertised prices and are more likely to allow postsale search than are price matching guarantees

is the business cycle characterized by deterministic chaos abstract tests are conducted on u s macroeconomic data for the presence of low dimensional deterministic chaos where deterministic chaos is defined as in grandmont s 1985 walras bowley lecture or in brock 1986 the idea is to test for evidence of endogenous instability causing the business cycle low order autoregressions are hard to reject with our methods evidence of chaos is weak but our tests may be too weak to detect it evidence of nonlinearity is present in employment 1950 i to 1983 iv unemployment 1949 i to 1982 iv monthly post war industrial production and pig iron production 1877 1937

chaos significance mechanism and economic applications imagine a bargaining model say involving diplomats negotiating tariff levels or a disarmament treaty in which each party has been instructed by higher headquarters to respond to each new offer by her opposite number with a counteroffer that is to be calculated from a simple reaction function provided in advance both negotiating parties are prohibited from revealing their own reaction functions to the other if the perfectly deterministic sequence of offers and counteroffers that must emerge from these simple rules were to begin to oscillate wildly and apparently at random the negotiations could easily break down as each party not understanding the source of the problem came to suspect the other side of duplicity and sabotage yet all that may be involved as we will see is the phenomenon referred to as chaos a case that is emphatically not pathological but in which a dynamic mechanism that is very simple and deterministic yields a time path so complicated that it will pass most standard tests of randomness chaos has become a subject of great interest to specialists and nonspecialists alike besides economics it has entered the literature of geometry physics ecology and meteorology it has been written about at length in the new york times magazine and scientific american as well as technical publications this article seeks to describe what it is how it works and what it means for economics

dynamic duopoly with best price clauses this article investigates best price clauses as a strategic devise to facilitate collusion in a dynamic duopoly game best price clauses guarantee rebates on the purchase price if a customer finds a better price after his purchase two different price clauses are distinguished most favored customer and meet or release i examine the collusive potential of both clauses in a finite horizon duopoly model with homogeneous durable goods in each period new consumers enter the market i show that in this context meet or release clauses have a greater anticompetitive potential than most favored customer clauses

the emergence of the factory system in 18th century england did transportation improvements really matter abstract rick szostak has recently suggested that a reduction in transport costs during the second half of the eighteenth century benefitted the factory system more than putting out the resulting change in relative costs he argues was primarily responsible for the emergence of the factory system in this period we maintain that szostak offers no substantive evidence to support his contention that the factory system was the main beneficiary of a reduction in transport costs and that the method he uses to assess changes in relative costs fails to include differences in the cost of a labour a major input other evidence that casts doubt upon his thesis is also ignored

how low is a guaranteed lowest price a game based on the bertrand duopoly model is constructed to study the effects of price guarantee policies before it chooses a list price a firm can make a binding commitment to match or beat its competitor s price the effectiveness of these price guarantee policies in facilitating price collusion depends on the solution concept used furthermore there exists an equilibrium in which neither firm offers any price guarantees and each firm sets price equal to marginal cost

output decisions and price matching theory and experiment we study the effects of price matching in a setting in which each firm selects both its price and output simultaneously we show that the availability of a price matching option leads to the cournot outcome in this setting our experimental study confirms this result in the laboratory our finding is a stark contrast to the one obtained in the standard price competition that the most likely market price in the presence of a price matching option is the monopolistic price in addition we show that price matching benefits consumers in markets with a large number of firms if a market has a few firms then the effects of price matching on consumers depend on the market demand and cost functions thus our study suggests that the effect of price matching depends on the strategic variables of the firms data and the online appendix are available at https doi org 10 1287 mnsc 2017 2788 this paper was accepted by eric anderson marketing

unilateral most favored customer pricing a comparison with stackelberg abstract if one firm in a price setting duopoly adopts a most favored customer pricing policy it can commit to a price which is higher than the bertrand price the equilibrium price however must be lower than the stackelberg leader price

can low price guarantees deter entry abstract this paper examines the strategic use of low price guarantees lpgs as an entry deterrent the entire space of contemporaneous lpg messages is partitioned according to their ability to deter entry and or increase the incumbent s profits while most price matching and price beating guarantees cannot deter entry into a perfectly contestable market there do exist special classes of price beating guarantees that enable the incumbent to prevent entry interestingly both price matching and price beating can be a part of the incumbent s strategy in subgame perfect equilibria of the game where the firms choose lpgs from 14 classes defined in the paper

rational choice and erratic behaviour in this paper we show that rational choice in a stationary environment can lead to erratic behaviour when preferences depend on experience we mean by erratic behaviour choice sequences that do not converge to a long run stationary value or to any periodic pattern early investigations of the effects of experience on choice goes back to pareto see also benhabib 1979 some keynesian theories of the consumption function incorporate the effects of experience and habit formation on current levels of consumption duesenberry 1949 modigliani 1949 and brown 1952 a general model of experience dependent choice was described in day 1970 and investigated in day and kennedy 1971 while the specific issue of the existence of stable representable long run consumer demand when tastes vary endogenously has been treated by gorman 1967 pollak 1970 1976 weizsaicker 1971 mccarthy 1974 and hammond 1976 pollak gave conditions for the representability of long run choice when the equations of preference dependence are linear and utility additive hammond in a generalization of these findings provides conditions for stable representable long run choice when preferences are acyclic a condition which in essence assures convergence to a long run choice

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

effective price matching a comment abstract corts economic lett 47 1995 417 showed that when allowing for price beating policies in addition to price matching policies the competitive outcome prevails in lieu of monopoly pricing i show by expanding the strategy set further to include effective price strategies the possibility of monopoly pricing is restored

non discrimination clauses in the retail energy sector the british energy regulator will soon review a non discrimination licence condition which it imposed to ensure that energy retailers charge the same mark up in different regions many consumers are loyal to incumbent firms necessitating heavy discounting by entrants to attract customers which had led to regional price discrimination matching characteristics of the energy market to models of discrimination we identify the necessary conditions for the licence condition to have a positive effect for consumers and explore whether the policy has helped potentially vulnerable consumers we conclude that the most likely effect of the licence condition is to reduce competition in the mainstream energy markets and welcome the regulator s latest review of the retail market

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

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

different selling strategies in bertrand oligopoly abstract i analyse a bertrand oligopoly game where firms can choose between selling strategies i price announcements ii price announcements and offers to price match i establish the set of nash equilibria and show that only the monopoly price nash equilibrium satisfies iterative dominance

matching own prices rivals prices or both many retailers promise that they will not be undersold by rivals and extend their promise to include their own future prices that is many retailers combine elements of both price matching guarantees and retroactive most favored customer clauses this is puzzling because the extant literature has shown that each practice independently has the potential to facilitate supracompetitive prices and thus one might think the two practices are substitutes in this paper we show that price matching guarantees and most favored customer clauses complement each other when offered unilaterally by a single firm and can lead to higher prices than either one could have facilitated by itself

on the robustness of the argument that price matching is anti competitive abstract the existing literature suggests that price matching leads to monopoly prices i show that this argument relies on an arbitrary and unrealistic restriction of the firms strategies in particular if firms may adopt price beating policies the competitive outcome prevails

bilateral most favored customer pricing and collusion in a two period differentiated products duopoly model most favored customer mfc pricing policies allow firms to commit to prices above the bertrand prices it is shown here however that unless a restrictive and unappealing assumption is made about demand there is no equilibrium in which both firms adopt mfc policies the restrictive assumption is that at least one firm s demand is more responsive to changes in its opponent s price than to changes in its own price otherwise firms have an incentive to deviate from a greater than bertrand price in the first period

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 theory of commodity price fluctuations this paper studies the price fluctuations of storable commodities that are traded in open markets and are subject to random shocks to demand or more particularly to supply it relaxes the common assumption that the shocks are identically and independently distributed in favor of temporally dependent and periodic disturbances the existence of a unique stationary rational expectations equilibrium is demonstrated for each of the models analyzed and testable implications of the models are derived an illustrative empirical investigation is then undertaken for the model with periodic disturbances using monthly time series observations for seven commodities over the period 1960 93

opportunism in multilateral vertical contracting nondiscrimination exclusivity and uniformity comment an input supplier selling to competing downstream firms would benefit from publicly committing at the outset to all contracts efficient commitment however would require complete contracts the authors study instead bilateral contracting without commitment regarding others terms each firm then fears that the supplier might opportunistically renegotiate another s contract to increase bilateral profit at the firm s expense the authors show that nondiscrimination clauses generally cannot curb such third party opportunism even with symmetric firms to reassure firms crude forms of commitment may be adopted this could explain the pervasiveness of exclusivity arrangements and the striking uniformity and intertemporal rigidity of franchise contracts copyright 1994 by american economic association

the welfare losses from price matching policies several recent papers argue that price matching policies raise equilibrium prices we add to this literature by considering potential welfare losses which have two sources harberger triangles from high prices and posner rectangles from over entry we compare price matching markets with entry to monopoly and price matching markets without entry and find that price matching with entry creates greater welfare losses than monopoly in markets with a low ratio of fixed to marginal cost we illustrate this result using parameters from the us wholesale gasoline and air travel markets and relate our model to price matching among nasdaq market makers

threshold arch models and asymmetries in volatility this paper attempts to enlarge the class of threshold heteroscedastic models tarch introduced by zakoian 1991a we show that it is possible to relax the positivity constraints on the parameters of the conditional variance unconstrained models provide a greater generality of the paths allowing for nonlinearities in the volatility cyclical behaviour is permitted as well as different relative impacts of positive and negative shocks on volatility depending on their size we give empirical evidence using french stock returns

the most favored nation pricing policy and negotiated prices previous work has viewed the most favored nation mfn contract as a practice capable of facilitating collusion among sellers but this paper shows that even a monopoly seller may gain by including the mfn provision in sales contracts we consider a case in which the seller negotiates price separately with each of two buyers by including a mfn clause in her contract with the first buyer the seller raises her cost of granting price concessions to the second buyer this increases the seller s bargaining strength with respect to the second buyer thereby helping her negotiate a higher price

do low price guarantees guarantee low prices evidence from competition between amazon and big box stores it has long been understood in theory that price match guarantees can be anticompetitive but to date scant empirical evidence is available outside of some narrow markets this paper broadens the scope of empirical analysis studying a wide range of products sold on a national online market using an algorithm that extracts data from charts i obtain a novel source of data from online price trackers i examine prices of goods sold on amazon before and after two big box stores target and best buy announced a guarantee to match amazon s prices employing both difference in difference and regression discontinuity approaches i robustly estimate a positive causal effect of six percentage points the effect was heterogeneous with larger price increases for initially lower priced items my results support anticompetitive theories which predict price increases for amazon a firm that did not adopt the guarantee and are consistent with plausible mechanisms for the heterogeneous impact

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

theoretical isolation and explanatory progress transaction cost economics and the dynamics of dispute two related goals are pursued first the development of and debates around oliver williamson s version of transaction cost economics are organised in terms of an emerging metatheoretical framework it proposes looking at economic theorising and its changes in terms of rival theoretical isolations which are often responses to challenging explanatory questions as a side product williamson s strategy of theorising is portrayed second using transaction cost economics as an illustration and as a source of inspiration the paper amends and refines the earlier framework of theoretical isolation by incorporating notions of explaining and explained items notions of progress in questions as well as increased causal penetration and increased degree of unification and the notion of the dynamics of dispute copyright 2004 oxford university press
