buyer experimentation and introductory pricing we study the pricing decisions of a monopolist seller in a two period model in which buyers and the seller are all uncertain about a good s quality we assume that buyers not only learn from experience but also may experiment that is increase the amount of information by consuming more we define an introductory price to be a first period equilibrium price lower than that which maximizes period 1 profit the motivation for introductory pricing is that under certain conditions the seller prefers its buyers to be better informed about quality a lower initial price increases consumption and hence information we consider two versions of the model identical buyers with a public signal of quality heterogeneous buyers who each receive a private quality signal 2001 elsevier science b v all rights reserved

frictionless commerce a comparison of internet and conventional retailers there have been many claims that the internet represents a new nearly frictionless market our research empirically analyzes the characteristics of the internet as a channel for two categories of homogeneous products books and cds using a data set of over 8 500 price observations collected over a period of 15 months we compare pricing behavior at 41 internet and conventional retail outlets we find that prices on the internet are 9 16 lower than prices in conventional outlets depending on whether taxes shipping and shopping costs are included in the price additionally we find that internet retailers price adjustments over time are up to 100 times smaller than conventional retailers price adjustments presumably reflecting lower menu costs in internet channels we also find that levels of price dispersion depend importantly on the measures employed when we compare the prices posted by different internet retailers we find substantial dispersion internet retailer prices differ by an average of 33 for books and 25 for cds however when we weight these prices by proxies for market share we find dispersion is lower in internet channels than in conventional channels reflecting the dominance of certain heavily branded retailers we conclude that while there is lower friction in many dimensions of internet competition branding awareness and trust remain important sources of heterogeneity among internet retailers

competition and the number of firms in a market are duopolies more competitive than atomistic markets this paper uses a variant of the standard search model to examine market equilibrium and the consequences for market equilibrium of an increase in the number of firms if marginal search costs increase with the number of searches then the demand curve facing any firm will be kinked with the elasticity of demand with respect to price decreases being less than with respect to price increases prices may not change in response to changes in marginal costs as the number of firms increases the maximum price that is consistent with equilibrium increases to the monopoly price but the minimum price decreases on the other hand if marginal search costs decrease with the number of searches equilibrium if it exists is characterized by a

price dispersion and seller heterogeneity in retail food markets price dispersion i e a homogeneous product being sold at different prices by different sellers is among the most replicated findings in empirical economics the paper assesses the extent and determinants of spatial price dispersion for 14 perfectly homogeneous food products in more than 400 retailers in a market characterized by the persistence of a large number of relatively small traditional food stores alongside large supermarkets the extent of observed price dispersion is quite high when prices in an urban area where the spatial concentration of sellers is higher are compared with those in smaller towns and rural areas differences in search costs and the potentially higher degree of competition do not yield lower prices other counteracting factors including differences in seller costs and consumer incomes make prices on average higher in the urban area for 11 of the 14 products considered for many but not all the products supermarkets proved to be less expensive than traditional retailers although average savings from food shopping at supermarkets were extremely low finally the results of the study provide evidence that retailers have different pricing strategies and these differences also emerge for supermarkets belonging to the same chain the results presented in the paper suggest that a variety of factors play a role in explaining price dispersion in addition to differences in seller costs the contemporaneous heterogeneity of retailers in terms of services provided and consumers in terms of search costs and preferences makes the emergence of monopolistic competition possible as well as allowing small traditional food retailers to remain in business

an examination of economic efficiency of russian crop production in the reform period this article examines economic efficiency ee of crop production of russian corporate farms for 1993 1998 ee declined over the period due to declines in both technical and allocative efficiency technical efficiency te results indicate that output levels could have been maintained while reducing overall input use by an average of 29 31 in 1998 depending on the method used while the allocative efficiency ae results show that costs could have been reduced about 30 the ee scores show that russian corporate farms could have increased efficiency by reducing the use of all inputs particularly fertilizer and fuel russian agriculture inherited machinery intensive technology from the soviet era which may be inappropriate given the relative abundance of labor in the post reform environment investment constraints have prevented the replacement of old machinery intensive technology with smaller scale machines that allow for a more labor using technology jel classification p2 q1

equilibrium price dispersion with consumer inventories abstract a model with two types of consumers shoppers and captives is constructed that leads to an equilibrium price dispersion shoppers may hold inventories of the good the level of consumer inventories leads to state dependent price dispersions it is shown that prices and quantities display negative serial correlation the model is tested using grocery store data which display the predicted correlations journal of economic literature classification numbers d43 l13 d83 l81

durable goods theory for real world markets the early 1970s witnessed three major advances in durable goods theory swan 1970 1971 and sieper and swan 1973 on optimal durability coase 1972 on time inconsistency and akerlof 1970 on adverse selection this paper surveys durable goods theory starting with these three contributions where much of the focus is on recent literature and on models that explain real world phenomena in addition to the ideas found in the contributions of swan coase and akerlof topics covered include why producers sometimes practice planned obsolescence the role of adverse selection in new car leasing and reasons for aftermarket monopolization

how do banks respond to shocks a dynamic model of deposit taking institutions abstract this paper proposes a dynamic model of the optimal choices of a bank that benefits from market power and takes into account the impact of the deposit generation process interbank lending borrowing emerges as a buffer that assists the bank in smoothing intertemporal adjustments in interdependent loan and deposit choices the bank smooths the impact of interest rates shocks on its customers to minimize the adjustments over time of the stocks of deposits and loans it does not however provide insurance against negative shocks of real origin that increase its expected default costs the predictions of the model help to shed light on the available empirical evidence and to analyze some recent developments of the banking industry

a new product growth for model consumer durables this article originally appeared in management science january 1969 volume 15 number 5 pp 215 227 published by the institute of management sciences a growth model for the timing of initial purchase of new products is developed and tested empirically against data for eleven consumer durables the basic assumption of the model is that the timing of a consumer s initial purchase is related to the number of previous buyers a behavioral rationale for the model is offered in terms of innovative and imitative behavior the model yields good predictions of the sales peak and the timing of the peak when applied to historical data a long range forecast is developed for the sales of color television sets

cyclic pricing by a durable goods monopolist in the model of this paper a monopoly seller of a durable good holds periodic sales as a means of price discrimination a new cohort of consumers enters the market in each period interested in purchasing the good either immediately or after a delay within each cohort consumers vary in their tastes for the good under broad conditions the seller will vary the price over time in most periods he will charge a price just low enough to sell immediately to consumers with a high willingness to pay periodically however he will drop the price far enough to sell to an accumulated group of consumers with a low willingness to pay

search unemployment in an overlapping generations setting this paper constructs an overlapping generations model in which the steady state equilibrium is characterized by the existence of search unemployment this dynamic general equilibrium model captures the possible existence of search unemployment in the long run despite the absence of exogenous shocks furthermore it allows for the wage offers distribution to be determined endogenously the effect of partial revelation of information on the existence of search unemployment in the long run is examined it is shown that search unemployment may be eliminated in the long run despite the persistence of the state of imperfect information this paper develops an overlapping generations model in which the steady state equilibrium is characterized by search unemployment 2 unemployment is created via a rational rejection of available wage offers in favor of further search for potentially more attractive offers the proposed dynamic general equilibrium model allows for the existence of long run search unemployment despite the absence of exogenous shocks and permits the presence of an endogenously determined nondegenerate wage offer distribution 3 the paper analyzes the trade off between revelation of information and the level of search unemployment in the long run in the absence of external disturbances the level of search unemployment would be expected to decrease as information becomes available in particular if information is fully revealed search unemployment is naturally eliminated exploring the likelihood of the existence of long run search unemployment in a deterministic world this study provides an example of partial revelation of information which eliminates search unemployment in the long run despite the persistence of the state of imperfect information 4 the proposed model presents a discrete infinite time horizon world where economic activity is conducted under imperfect information in every period a single homogeneous good is produced using two factors capital and labor in the production process the aggregate endowment of labor is exogenously given in

dynamic pricing of new experience goods we develop a dynamic model of experience goods pricing with independent private valuations we show that the optimal paths of sales and prices can be described in terms of a simple dichotomy in a mass market prices are declining over time in a niche market the optimal prices are initially low followed by higher prices that extract surplus from the buyers with a high willingness to pay we consider extensions of the model to integrate elements of social rather than private learning and turnover among buyers

allocative efficiency in russian agriculture the case of fertilizer and grain during russia s economic transition the amount of fertilizer as well as other tradable inputs such as fuel used in agricultural production has fallen substantially mineral fertilizer use in 2000 was 86 lower than in 1990 while since the mid 1990s russia has exported more than 80 of its fertilizer output this paper examines the allocative efficiency of russian use of mineral fertilizer to produce grain assessed from the point of view of both domestic and trade prices we use the results to examine whether fertilizer is being used at its optimal level and whether the major changes in the volumes of fertilizer use and trade during transition have been economically rational implications for agricultural policy in russia are then discussed methods and data

intertemporal pricing and consumer stockpiling we study a dynamic pricing problem for a class of products with stable consumption patterns e g household items staple foods consumers may stock up the product at current prices for future consumption but they incur inventory holding costs we model this situation as a dynamic game over an infinite time horizon in each period the seller sets a price and each consumer chooses how many units to buy we develop a solution methodology based on rational expectations by endowing each player with beliefs we decouple the dynamic game into individual dynamic programs for each player we solve for the rational expectations equilibrium where all players make optimal dynamic decisions given correct beliefs about others behavior in equilibrium the seller may either charge a constant fixed price or offer periodic price promotions at predictable time intervals we show that promotions are useful when frequent shoppers are willing to pay more for the product than are occasional shoppers we also develop several model extensions to study the impact of consumer stockpiling on the seller s inventory production and rationing strategies

measuring the effects of search costs on equilibrium prices and profits abstract this paper assesses the effects of search costs on equilibrium prices and profits using an estimated model of demand and costs in a laundry detergent market i find that some firms profits initially rise and then fall with search costs overall the magnitude and direction of the search costs effects on prices and profits are heterogeneous this is because search costs create conflicting incentives for a firm to reduce prices to attract the attention of searching consumers yet also raise prices to harvest profit from consumers who are unaware of competing products these effects can vary with the relationship between the firms actual prices and the consumers pre search beliefs about prices

price dispersion in an automobile insurance market from automobile insurance data for alberta over the period 1974 81 we find thatpremiums are highly correlated across driver classes in a given year but that premiums for a given driver class are not correlated over a period of more than 5 years firms relative market shares among drivers over age 25 and married males under 25 are inversely related to their deviations from the mean premiums in these driver classes the variance of real premiums decreases with the numberof firms in the market and increases with the real loss cost per car insured and the number of cars insured from these results we conclude that the price dispersion in automobile insurance in alberta is based on costly consumer search

a theory of clearance sales clearance sales are widely used by firms as an intertemporal selling policy in particular in markets where firms face demand uncertainty and need to choose capacity in advance clearance sales consist in charging a high price initially but then lowering the price in the sales period high valuation consumers purchase the good at the high initial price so as to avoid rationing at the low price while low valuation consumers wait for the price to drop we develop a simple model of intertemporal monopoly pricing under demand uncertainty and show that clearance sales may be the optimal intertemporal selling policy

mechanism design by competing sellers a dynamic model with many sellers and buyers is constructed agents failing to trade may trade in the next period an equilibrium is found where sellers hold identical auctions and buyers randomize over the sellers they visit the distribution of buyer valuations is endogenous an auction with efficient reserve is an optimal mechanism from each seller s point of view in spite of the ability of any seller to alter the distribution of buyer types participating in the seller s mechanism by altering the mechanism copyright 1993 by the econometric society

the contributions of the economics of information to twentieth century economics in the e eld of economics perhaps the most important break with the past one that leaves open huge areas for future work lies in the economics of information it is now recognized that information is imperfect obtaining information can be costly there are important asymmetries of information and the extent of information asymmetries is affected by actions of e rms and individuals this recognition deeply affects the understanding of wisdom inherited from the past such as the fundamental welfare theorem and some of the basic characterization of a market economy and provides explanations of economic and social phenomena that otherwise would be hard to understand i introduction the century coming to a close has seen vast changes in economics in both ideas and methodology upon ree ection it is remarkable however how many of the seeds of advances in this century were sowed in the previous i would argue that perhaps the most important break with the past one that leaves open huge areas for future work lies in the economics of information the recognition that information is imperfect that obtaining information can be costly that there are important asymmetries of information and that the extent of information asymmetries is affected by actions of e rms and individuals has had profound implications for the wisdom inherited from the past and has provided explanations of economic and social phenomena that otherwise would be hard to understand in this essay i wish to argue that information economics has had directly and indirectly a profound effect on how we think about economics today eighteenth and nineteenth century antecedents to be sure marshall and other nineteenth century economists talked about problems of imperfect information but with one exception discussions of information were obiter dicta caveats at the end of the analysis they were never at the center

coupons and everyday low prices price competition with multiple instruments abstract a simple two stage game is examined where firms compete in prices by chosen pricing instruments those considered include a simple uniform pricing technology and a promotional pricing technology like an advertised discount coupon consumers are separated by types informed and uninformed therefore a motive for price competition exists for the purpose of separating the two types of consumers it is shown that the sustainability of an asymmetric choice of pricing instrument between the two firms will prevail in a duopoly market in equilibrium consequently the coexistence of two different pricing schemes is viable even when firms are otherwise symmetric jel classification l1 l13 coupons et bas prix tous les jours concurrence par les prix a l aide de multiples instruments ce memoire examine un simple jeu a deux etapes dans lequel des entreprises se concurrencent par les prix a l aide d un instrument particulier les instruments consideres incluent une simple technologie de prix uniforme et une technologie de prix de promotion sous la forme de l annonce d un coupon d escompte on divise les consommateurs en deux groupes ceux qui sont informes et ceux qui ne le sont pas un des motifs pour ce genre de concurrence est de separer les deux types de consommateurs on montre qu on peut soutenir un choix asymetrique d instrument de tarification entre les deux entreprises dans un marche de duopole en equilibre en consequence la coexistence de deux strategies de prix differentes est viable quand les entreprises sont symetriques sous tous les autres rapports

decentralized dispersed exchange without an auctioneer abstract we stimulate exchange among geographically dispersed agents who face real costs of communication along with bounds to rationality and calculation exchange is entirely decentralized it is initiated by individual agents who broadcast costly messages indicating their interest in trade it is accomplished by bilateral bargaining between pairs of agents agents use the information gained from previous attempts at local trade to calculate their search strategies for succeeding rounds this decentralized mechanism can achieve a substantial improvement in the allocation of resources and the average welfare of agents in comparison with a randomized initial endowment but in comparison with walrasian equilibrium agents who begin with endowments of equal value end up with substantially unequal wealth although the initial inequality of utility is reduced

information and economic analysis a perspective ten years ago i delivered a paper before this group with the title information and economic analysis i chose the title deliberately i did not call the subject on which i was speaking the economics of information because to do so would have been to suggest that my topic like the economics of agriculture or the economics of industry or the economics of labour represented another branch of specialisation within economics i wanted to suggest that informational considerations were in fact central to the analysis of a wide variety of phenomena that they constituted a central part of the foundations of economic analysis at the time though economists had long paid lip service to the importance of information there was little formal literature the last decade has seen a burgeoning of the literature it has become to the late 7o s and early 8o s what growth theory was to the early 6o s and it has been greeted with some of the same scepticism there seems to be a myriad ofspecial cases and few general principles the little examples are often contrasted unfavourably with the generality of general equilibrium theory what have we learned have diminishing returns set in are there fruitful directions for future research and if so what are they these are the questions which i wish to address here the work of the past decade has made i think a fundamental and lasting contribution to economic analysis the contributions have been both negative and positive we have learned that much of what we believed before is of only limited validity that the traditional competitive equilibrium analysis though having the superficial appearance of generality in terms of superscripts and subscripts is indeed not very general the theory is not robust to slight alterations in the informational assumptions it is but a special and not very plausible example among the possible set of informational assumptions which can be employed to characterise an economy at the same time the theory has been able to provide insights into phenomena about which the traditional model had nothing to say or which seemed inconsistent or inexplicable within the competitive paradigm it has provided some of the micro foundations for macro economics it has provided the basis of a new theory of the firm of a new new welfare economics and of a theory of economic organisation including a comparison of economic

a simple model of price dispersion abstract this article considers a simple stock flow matching model with fully informed market participants unlike the standard matching literature prices are assumed to be set ex ante when sellers pre commit themselves to sell their products at an advertised price the unique equilibrium is characterized by price dispersion due to the idiosyncratic match payoffs in a marketplace with full information this provides new insights into the price dispersion literature which instead commonly assumes that buyers are not perfectly informed and engage in a costly search

word of mouth model of sales in this paper i develop a model of the dynamic pricing of a monopolist while information about its product is diffusing through word of mouth individuals who purchase the product engage in word of mouth with their friends the main result establishes that prices optimally fluctuate over time a monopolist sets prices over time to balance extracting profits in the short term with increasing information diffusion through word of mouth and thereby the population of potential consumers in the future the key state variable for determining this tradeoff is the distribution of valuations of the individuals on the edge of the diffusion this distribution of valuations is determined by the history of prices and changes over time our analysis reveals that prices must move up and down infinitely often

economic policy reform in developing countries the role and management of political factors abstract increased recognition of the role of sound economic policies in economic development has stimulated interest in the political and administrative factors that determine policy responses of different developing countries this article provides a critical introduction to three further papers in this special section of world development all of which deal with political and administrative dimensions of economic policy reform certain common themes are isolated and addressed these include the role of political analysis and explanation the concept of political will to undertake reforms and the importance of the implementation phase in the reform process

local network externalities and market segmentation this paper models interaction between groups of agents by means of a graph where each node represents a group of agents and an arc represents bilateral interaction it departs from the standard katz shapiro framework by assuming that network benefits are restricted only amongst groups of linked agents it shows that even if rival firms engage in bertrand competition this form of network externalities permits strong market segmentation in which firms divide up the market and earn positive profits the analysis also shows that some graphs or network structures do not permit such segmentation while for others there are easy to interpret conditions under which market segmentation obtains in equilibrium c 2009 elsevier b v all rights reserved

equilibrium price dispersion in retail markets for prescription drugs this study seeks to establish the empirical importance of price dispersion due to costly consumer search by examining retail prices for prescription drugs posted prices in two geographically distinct markets are shown to vary considerably across pharmacies within the same market even after one controls for variation due to pharmacy differences pharmacy heterogeneity accounts for at most one third of the observed price dispersion the empirical analysis hinges on the observation that consumers incentives to price shop depend on characteristics of the drug therapy cross sectional patterns in price distributions across drugs are consistent with the predictions of a search model prices for repeatedly purchased prescriptions for which the expected benefits of search are highest exhibit significant reductions in both dispersion and price cost margins

strategic pricing consumer search and the number of firms discover prices there are three distinct price dispersed equilibria characterized by low moderate and high search intensity the effects of an increase in the number of firms on search behaviour expected prices price dispersion and welfare are sensitive i to the equilibrium consumers search intensity and ii to the status quo number of firms for instance when consumers search with low intensity an increase in the number of firms reduces search does not affect expected price leads to greater price dispersion and reduces welfare in contrast when consumers search with high intensity increased competition results in more search and lower prices when the number of competitors in the market is low to begin with but in less search and higher prices when the number of competitors is large duopoly yields identical expected price and price dispersion but higher welfare than an infinite number of firms a question that has received much attention in economic theory is how the number of competitors and market outcomes are related despite the existence of work showing the contrary see e g satterthwaite 1979 rosenthal 1980 the prediction that emerges from a market where firms interact in a cournot fashion has come to dominate economic thought namely that an increase in the number of competitors leads to larger aggregate production lower market price and improved market performance measured in terms of some social welfare criterion ruffin 1971 this paper challenges the generality of this belief by presenting an oligopoly model with consumer search where the equilibrium expected price may be constant increasing or nonmonotonic in the number of firms we present an economy with two types of consumers consumers who search for prices at no cost fully informed and consumers who must pay a fixed search cost for each price quotation they observe less informed 1 all buyers have the same willingness to pay for the good and buy either a single unit or nothing at all on the supply side of the market there are n firms producing a homogeneous good at constant marginal cost we analyse a one shot simultaneous move game firms set prices and consumers decide how many prices to search for at the same moment in time our model is essentially an oligopolistic version of burdett and judd 1983 where some consumers search costlessly in this model consumers search using a fixed sample size search strategy i e they choose the number of prices to observe before receiving any offer nonsequential search is appealing when consumers find it more advantageous to gather price information quickly morgan and manning 1985 this occurs when the search outcome is observed with delay and delay is costly for instance an mba graduate looking for a job 1 the presence in the model of consumers who search costlessly captures the fact that some people have a

collusion with intertemporal price dispersion we develop a theory of optimal collusive intertemporal price dispersion dispersion clouds consumer price awareness encouraging firms to coordinate on dispersed prices our theory generates a collusive rationale for price cycles and sales patient firms can support optimal collusion at the monopoly price for less patient firms monopoly prices must be punctuated with fleeting sales the most robust structure involves price cycles that resemble edgeworth cycles low consumer attentiveness enhances the effectiveness of price dispersion by reducing the payoff to deviations involving price reductions however for sufficiently low attentiveness price rises are also a concern

intertemporal substitution and storable products storable products allow consumers to time their purchases to exploit price fluctuations it has been documented that during promotions consumers buy more the additional purchases are potentially intended not only for current use but to be stockpiled for future consumption this paper discusses the predictions of a consumer inventory model and reviews the available evidence we then discuss the implications for demand estimation and present estimates of jel lo l4 dl d4 the economic magnitude of the dynamic effect of storability jel lo l4 dl d4 jel lo l4 dl d4

informative price advertising in a sequential search model the purpose of this paper is to study the role and implications of price advertising when shopping trips are costly to consumers to do so we introduce advertising into an optimal sequential search model information about prices is both gathered by consumers and disseminated by firms consumers search sequentially and stores advertise with various intensity when it is in their interest to do so our model has a unique equilibrium exhibiting priee dispersion the model generates predictions about the shape of the price distribution and firms advertising behavior we explore the effects of entry and find that when initial advertising costs at zero level of effort are precisely zero entry drives the equilibrium to the perfectly competitive outcome however when initial marginal advertising costs are positive entry drives prices higher and while the informed consumers almost surely locate competitive prices welfare does not necessarily increase finally we compare the effectiveness of the two informational channels when advertising costs shrink prices become competitive however when search costs shrink prices remain bounded above marginal production costs

the impact of collusion on price behavior empirical results from two recent cases abstract we use extended arch and garch models to examine the differences in the behavior of the first two moments of the price distribution during collusive and competitive phases of two recently discovered conspiracies citric acid and lysine according to our results the conspirators managed to raise prices by 9 and 25 cents per pound in the short run relative to non collusive periods also the variance of prices during the lysine conspiracy was lower and the variance of prices during the citric acid conspiracy was higher than during more competitive periods the proposed methodology may be used for antitrust screening and prosecution purposes

price and advertising signals of product quality we present a signaling model based on ideas of phillip nelson in which both the introductory price and the level of directly uninformative advertising or other dissipative marketing expenditures are choice variables and may be used as signals for the initially unobservable quality of a newly introduced experience good repeat purchases play a crucial role in our model a second focus of the paper is on illustrating an approach to refining the set of equilibria in signalling games with multiple potential signals

success and failure of reform insights from the transition of agriculture this paper analyzes the linkages between the reform strategies in transition countries and economic performance the authors focus on agriculture because of the sharpness of the policy changes fundamental differences among countries and relative simplicity of agricultural relationships the authors document post reform performance in the transition countries of asia and europe the authors show how a pricing reform and subsidy reductions b land rights reform and policies that affect farm restructuring and c the presence institutions that facilitate exchange either markets or market substitutes affect output and productivity the paper ends with general lessons on reforms and transition

the timing of sales this paper presents a model of intertemporal price discrimination a fixed number of sellers produce a homogeneous good consumers with different preferences enter the market in each period and leave when they make a purchase the sellers typically vary their prices over time charging a high price in most periods but occasionally cutting the price to sell to a large group of customers with a low reservation price in some equilibria all stores lower their price at the same time and to the same level

agricultural output and productivity in the former soviet republics the paper reviews agricultural development in the fifteen former soviet republics over the period 1965 1997 production functions are estimated and productivity differences and changes calculated large differences were found in terms of productivity and growth between the republics the differences grew after 1990 reflecting variation in reform policies

wine retail price dispersion in the united states searching for expensive wines similar to other markets in which deviations from jevons law of one price is the norm rather than the exception the retail wine market in the united states is characterized by large price dispersions drawing on a large sample of retail prices from wine searcher com we find an average per wine coefficient of variation of 23 percent some of this is due to differential market conditions especially state regulations our evidence suggests that dispersion also depends positively on price levels after controlling for consumer market and state heterogeneity

assessing policy implementation success observations from the philippines abstract this article analyzes the establishment and start up of the one stop shop inter agency tax credit and duty drawback center in the philippines it briefly describes the policy change agenda that was embodied in the center s creation and outlines developments during its first eight months of existence it explores the impact of bureaucratic complexity on the ability of center management and staff at the department of finance dof to implement the policy reform agenda finally it examines to what extent the center s managers actually adopted the principles and techniques of strategic management and if they did what difference it made to successful implementation of that policy agenda

durable goods monopoly with entry of new consumers this paper analyzes a model of a dynamic monopolist who produces at constant unit cost each period a new cohort of consumers enters the market each entering cohort is identical consumers within a cohort have different tastes for the good my main results are if players are sufficiently patient any positive average profit less than the maximum feasible level can be attained in a subgame perfect equilibrium in the subset of subgame perfect equilibria in which players use stationary strategies the seller cannot make sales at prices significantly greater than the lowest willingness to pay when period length goes to zero and the seller attains the maximum profit when commitment is feasible by charging the same static monopoly price in every period this paper analyzes a model of a dynamic monopolist who operates in a market in which there is a regular flow of new consumers the seller produces a durable good at constant unit cost each period a new cohort of consumers enters the market consumers wish to buy exactly one unit of the item but are willing to wait resales are not allowed each entering cohort is identical

consumer stockpiling and competitive promotional strategies an examination of brand prices in several categories reveals that the distribution of prices is multimodal with firms offering shallow and deep discounts another interesting feature of these distributions is that they may have holes in the interior of the support these pricing distributions do not occur in extant theoretical models of price promotions we develop a dynamic model of competition in which some price sensitive consumers stockpile during periods of deep discounts a game theoretic analysis of our model generates a multimodal pricing distribution with a hole in the interior of the support consumer stockpiling in our model also gives rise to negative serial correlation in prices this is consistent with our empirical observation of the pricing distribution of several brands across multiple categories in the iri marketing data set we generate several interesting insights into firms optimal promotional strategies and their interplay with the clientele mix market structure and other market factors we find that in equilibrium stockpiling by price sensitive consumers neither harms nor benefits firms when they adopt equilibrium strategies interestingly when price sensitive consumers stockpile even increased consumption as a result of stockpiling does not lead to higher profits for firms

limits of state strength toward an institutionalist view of economic development nomic development attempted to explain why growth did not occur occurred slowly or occurred in a distorted dependent form the impressive economic performances of the east asian newly industrialized countries nics have changed this many noneconomists as well as some economists are now focusing on the political bases of development rather than underdevelopment there are differences among these analysts some distance themselves from neoclassical economics by emphasizing the importance of getting the prices wrong others acknowledge the utility of market conforming policies but common to recent studies of nics is the belief that growthpromoting economic policies require certain types of domestic political institutions analysts have emphasized the utility of strong states in this regard 2 through an analysis of efforts to promote local auto manufacturing in southeast as well as east asia this article argues for an institutionalist approach to development that goes beyond statism the resolution of collective action problems is central to statist writings development requires that private returns to individual activities be brought in line with the broader needs of national development 3 two factors are presumed to obstruct such harmonization in developing

storable good monopoly the role of commitment we study dynamic monopoly pricing of storable goods in an environment where demand changes over time the literature on durables has focused on incentives to delay purchases our analysis focuses on a different intertemporal demand incentive for consumers the key force on the consumer side is advance purchases or stockpiling this stockpiling motive can be present in the case of standard durables as well in environments unmodeled in the prior literature we show that if the monopolist cannot commit then prices are higher in all periods and social welfare is lower than in the case in which the monopolist can commit this is in contrast with the durable goods analysis in the literature on the coase conjecture
