an analysis of the tradeoff between advertising and price discounting the authors examine an important influence on the price advertising tradeoff the ratio of price and advertising elasticities their theoretical analysis stresses the centrality of the elasticity r

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

a friction model for describing and forecasting price changes this paper presents a new friction model for describing the price changes of a product or brand over time and for forecasting both the timing and magnitude of such changes from one period to the next after a review of the related pricing literature we present our model and a modified controlled random search procedure for estimating its parameters the model is applied to describe and forecast the weekly mortgage interest rates for a local bank in the philadelphia area finally limitations and several potential applications of this methodology are discussed

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

product variety informative advertising and price competition abstract in many product categories consumer tastes are diverse and firms use finely targeted advertising to inform consumers about their products this article proposes a model of informative advertising that allows for diverse consumer tastes and multiple competing firms using this framework the authors analyze how diversity in consumers tastes informative advertising and improvements in advertising technology may influence prices first informative advertising can lead to lower prices if consumer valuations are high however if consumer valuations are low informative advertising can lead to higher prices second when consumer valuations are high price increases with greater diversity in tastes though this result reverses if consumer valuations are low third improvements in advertising technology lead to higher levels of advertising when consumer valuation is high but the opposite effect can occur when consumer valuation is low the authors relate these theoretical findings to previous e

endogeneity in brand choice models applications of random utility models to scanner data have been widely presented in marketing for the last 20 years one particular problem with these applications is that they have ignored possible correlations between the independent variables in the deterministic component of utility price promotion etc and the stochastic component or error term in fact marketing mix variables such as price not only affect brand purchasing probabilities but are themselves endogenously set by marketing managers this work tests whether these endogeneity problems are important enough to warrant consideration when estimating random utility models with scanner panel data our results show that not accounting for endogeneity may result in a substantial bias in the parameter estimates

the price elasticity of mass preferences i compare the price elasticity of economic and political preferences my central hypothesis is that willingness to pay whether expressed verbally or through cash transactions is more price elastic for economic consumption goods than for public goods i find that increases in price greatly diminish the proportion of people willing to pay for consumer goods such as housing or hardback books whereas the proportion willing to pay more in taxes to support a public good such as environmental protection or shelter for the homeless is much less responsive to changes in price i conclude by discussing the theoretical and political implications of willingness to pay for public and private goods

cost benefit models for explaining consumer choice and information seeking behavior while it provides excellent descriptions of behavior existing consumer research on information seeking and processing largely fails to explain why consumers engage in various types of activities this paper presents an economic framework for measuring costs benefits of search behavior which can help to resolve these questions this work shows how such a framework can lead to testable hypotheses about information seeking and discusses how operational measures of economic incentives to search can be developed and employed

attraction versus linear and multiplicative market share models an empirical evaluation linear and multiplicative market share models are compared with the attraction specification on the basis of both predictive and descriptive measures the data used represent 15 brands in three dif

manufacturer allowances and retailer pass through rates in a competitive environment a commonly held belief has grocery and mass merchandise retailers gaining power relative to the upstream consumer package goods manufacturers one of the major justifications for this belief is that manufacturers are now giving retailers more side payments such as trade allowances slotting allowances etc however a number of researchers have shown that these concessions have not translated into increased profit for the retailer relative to the manufacturer this paper explores via an analytic model why one might see retailers getting concessions from the manufacturer without being able to translate them into high profits we do this by representing the interaction between the channel members as a one period profit maximizing game where manufacturers decide on how large a side payment i e a concession to give to each retailer and retailers decide on how much of this side payment to use to promote the manufacturer s product at the heart of our model is a demand function for each product offering i e a specific brand sold by a specific retailer this demand function is linear in own and other s prices but based on empirical evidence is assumed to be nonlinear in the effects of merchandising activities e g short term price discounts better shelf space advertising etc specifically merchandising effects are modeled with a square root function that also acknowledges most short term promotional effects result in brand or store switching versus increase category volume the model is composed of six parameters these are the inherent popularity of the brand at a particular outlet own price sensitivity cross but within the store price sensitivity customer s sensitivity to within store promotion activities customer s sensitivity to between store promotional activities and the degree to which promotional activities yield incremental product category sales we use our underlying demand formulation to find the equilibrium solution to the full information stackelberg leader game for different store and brand loyalty environments as captured by our six parameters these parameters are chosen based on empirical evidence to span possible market conditions that each channel member might have our findings and modeling efforts should be of interest to analytic channel modelers and scholars interested in the mass merchandising and grocery store industries for a theoretical point of view we build upon the case 4 model of lee and staelin 1997 to allow for promotional activities from a substantive point of view we show that manufacturers will freely give retailers side payments even though they know these retailers will pocket a substantial portion of this concession moreover we identify conditions within our model that lead to larger allowances lower pass through rates and lower retail profits outcomes that are compatible with recent industry trends in addition we highlight the difference in effect on profits prices etc of changes in consumers sensitivity to inter store differences in storewide merchandising activities one of the more counter intuitive results of these analyses is that it is in the manufacturer s best interest to help retailers increase their spatial monopoly by decreasing consumers tendency to cross store shop because of merchandising activities

normal costs and demand effects in price setting a study of retailing the study aims at contributing to the debate whether there are demand effects in models that seek to explain prices as mark ups on costs for costs it considers actual costs normal costs and an intermediate model with a partial adjustment to the deviation of actual from normal costs for demand effects it considers an effect on the price level of a change of demand with an allowance for asymmetry between demand growth and demand decline tests and estimates are conducted on the basis of data from retailing

competitive price and quality under asymmetric information we present an analysis of equilibrium in markets with asymmetrically informed consumers some consumers know both price and quality of all sellers whereas others know neither but may search among sellers the equilibrium correlation between price and quality generally increases with the level of information in the market and can be negative when this level is sufficiently small a meta analysis of the available empirical studies strongly supports the model s predictions

taxes and dividends the uk evidence abstract this paper provides empirical evidence on the simultaneous effects of both corporation and personal income taxes on dividend payment adjustments and on the behaviour of share prices on the ex dividend dates the results show that companies set their dividend policies to minimise their tax liability and to maximise the after tax return of their shareholders in particular firms that are unable to deduct the advanced corporation tax from their tax liability are found to pay low dividends in addition consistent with the tax hypothesis we find that the differential taxation of dividends and capital gains results in a decrease in ex day share prices by significantly less than the amount of the dividend there is no evidence of a tax induced dividend clientele

concentration of marketing channels and brand level retailer margins evidence from japan this article investigates the impacts of marketing channel concentration at each distributive channel stage on brand level retailer gross margins a unique official japanese dataset the national survey of prices which reports brand level wholesale prices as well as retail prices of national brand items in various consumer product categories enables us to estimate the retail margin directly for each specified brand the most notable conclusion is that an inverse relationship is found between brand level retailer margins and the degree of wholesaler concentration which is consistent with empirical results in previous marketing and economic studies that investigated the impacts of manufacturer concentration on category level retailer margins

seasonality and the effect of advertising on price does advertising make markets more or less competitive this paper lays out an econometric strategy for estimating the effect of advertising on prices that exploits seasonal demand and imperfect targeting of consumers we find mostly negligible effects of advertising on prices at monthly frequency among the 35 of 131 product categories with sufficient advertising seasonality to justify second stage estimation only nine have a significant effect and those are typically small this finding is essentially the result of the much greater seasonality in advertising than price

research note additional learning and implications on the role of informative advertising observers argue that evidence for the persuasive role of advertising comes from competitive categories where increases in advertising lead to higher average prices conversely others claim that advertising serves a purely informational role here higher levels of advertising lead to better informed consumers and this should increase competition and stimulate lower prices the objective of this study is to neither confirm nor refute either of these perspectives it is rather to show that increases in informative advertisingalone can lead to both higher or lower prices i further show that the direction of this relationship depends on the level of differentiation between competing firms similar to grossman and shapiro 1984 i examine conditions where the differences between competing products are small but i also examine conditions where the differences are significant the role of advertising is to inform consumers about individual products and higher advertising for a product means that more of the potential market knows about it higher levels of advertising increase the relative importance of fully informed consumers compared to partially informed consumers this dynamic is the basis for explaining why informative advertising can push prices either up or down in a uniformly distributed spatial market

toward a reconciliation of market power and information theories of advertising effects on price elasticity prior work on the economic effects of advertising has presented conflicting views some authors have suggested that advertising creates market power by artificially differentiating brands and thereby lowering price elasticity others have viewed advertising as an efficient source of information about the existence of substitutes arguing that advertising increases price elasticity the present research proposes a unifying theoretical model in which advertising affects price elasticity through its influence on two mediating constructs the size of the consideration set and the relative strength of preference pretests 1 and 2 examine the effects of advertising on these two constructs results from the main experiment show that in accordance with the theoretical framework the same advertisements that increased price elasticity in some decision environments decreased it in others

empirical generalizations about market evolution and stationarity we present empirical generalizations about conditions under which marketing variables evolve or remain stationary we first define evolution statistically and make the case why it is an important concept for increasing our understanding of long run marketing effectiveness we then briefly review ways in which evolution can be tested empirically from readily available data we present a database of over 400 prior analyses and catalog the relative incidence of stationarity versus evolution in market performance and marketing spending we find that evolution is the dominant characteristic for sales and marketing mix spending but that stationarity is the dominant characteristic for market share thus we find strong support for the conjecture that many markets are in a long run equilibrium where the relative position of the players is only temporarily disturbed by their respective marketing activities we assess the impact of a number of covariates on the likelihood of finding stationarity evolution in sales

ex dividend day stock price behavior the case of the 1986 tax reform act this paper analyzes the behavior of stock prices around ex dividend days after the implementation of the 1986 tax reform act that dramatically reduced the difference between the tax treatment of realized long term capital gains and dividend income in 1987 and completely eliminated the differential in 1988 we show that this tax change had no effect on the ex dividend stock price behavior which is consistent with the hypothesis that long term individual investors have no significant effect on ex day stock prices during this time period the results indicate that the activity of short term traders and corporate traders dominates the price determination on the ex day

demand uncertainty and sales a study of fashion and markdown pricing the theory of clearance sales is expanded and applied to explain why markups markdowns and the frequency of sales of merchandise sold by department stores have increased dramatically in recent years and why they differ across merchandise groups tha major theme of the paper is that the growing role of fashion and product variety is an important reason for these increases and for the differences between merchandise groups the growing importance of fashion is illustrated by documenting the declining use of whites and the increasing use of colors and prints estimates of the effects of imports and technological and demographic changes on markups and markdowns are presented copyright 1988 by american economic association

the effect of price advertising on prices evidence in the wake of 44 liquormart the 44 liquormart decision eliminating rhode island s ban on liquor price advertising made rhode island the subject of a natural experiment for measuring the effect of advertising on prices using massachusetts prices as controls we find that advertising stores substantially cut only prices of the products that they advertise prices of other products at both advertising and nonadvertising stores do not change advertising stores cut their prices on products advertised by rivals while nonadvertising stores do not we find no reductions in price dispersion across stores newspaper advertising stores appear to draw a higher share of customers after they advertise

informative advertising competition or cooperation there are two main views of advertising the informative view and the persuasive view this thesis studies aspects of the informative view one aspect of interest is whether firms can benefit from collusion on advertising even though advertising is only informative if so will this enhance or lower welfare there are several reasons why firms may want to collude on adver tising first the legal field is tilted in favour of nonprice collusion second it is not at all obvious that collusion on price is more profitable than collusion on advertising and third the analyses of grossman and shapiro 1984 and others show that profits can be increased by restricting advertising in paper 1 we examine firms incentives to collude on advertising and the implications for welfare we find that collusion on advertising and competition on price is more profitable than competition on both price and advertising we also find that semicollusion on advertising is detrimental to welfare this suggests a need for monitoring especially since it is in the interest of firms to restrict price advertising we also compare semicollusion on price to semicollusion on advertising we find that in general semicollusion on price does not lead to higher profits compared to semicollusion on advertising hence we lend theoretical support to the empirical literature that consistently find evidence of semicollusion on advertising rather than on price another important issue concerns the effect on prices and profits of ad vertising only a subset of the product range many firms in particular those in the retail sector sell a wide variety of products but only advertise a few recent empirical evidence suggests that prices of unadvertised products are higher milyo and waldfogel 1999 theoretically little is known in paper 2 we study the effects of advertising only a subset of products we allow for both low and high differentiation and at the same time we explicitly model the advertising decision we find that the extend of differentiation between competing firms plays an important role in the analysis of loss leader pricing when firms sell products with the same reservation price loss leader pric ing obtains only when differentiation is low when products are less similar however price competition is less intense and as a result firms advertise prices above marginal cost our loss leader pricing results enable us to shed some light on the seemingly paradoxical empirical findings in the marketing literature that loss leader pricing fails to increase store traffic loss leader sales and hence to increase profits we also consider a different subject price discrimination although it is well understood that movements in the exchange rate have a bearing on firm profitability and hence affect firm behaviour the role of exchange rate variability in the firm s choice of the number of varieties to produce has to my knowledge not been explored this despite the fact that the product mix is an important aspect of firm strategy by tinkering with the number of varieties a firm can bolster its ability to extract consumer surplus in paper 3 we explore this issue we show that variability in the exchange rate induces the firm to vertically segment markets i e offer two varieties in each market this happens because exchange rate variability affects income dispersion and hence the firm s incentives to extract consumer surplus to better extract surplus the firm offers two price quality menus high quality variant priced high for top end surplus extraction and a low quality variety priced low to address market coverage concerns

the impact of heterogeneity in purchase timing and price responsiveness on estimates of sticker shock effects the notion that individuals have an internal reference price against which they compare observed prices is well supported by several psychological theories empirically several papers in the marketing literature employing scanner panel data have modeled the impact of reference prices on brand choice via the sticker shock formulation in which consumers evaluate choice alternatives using differences between shelf prices and reference prices most of the studies reported thus far have not accounted for heterogeneity in price response among consumers and have typically imputed reference prices from the shelf prices of brands that a consumer is supposed to have observed on previous purchases in the category since category marketing activity can differentially affect the purchase timing of households we argue that this measure of reference price may follow certain systematic patterns across consumers and when combined with unaccounted for price response heterogeneity may result in a spurious sticker shock effect specifically we show that estimates of sticker shock are biased upward if households that are price sensitive in the brand choice decision are also more responsive to category promotion activity in their purchase timing decision we discuss some general conditions under which the bias occurs and conduct a simulation experiment to confirm our specific hypotheses our simulation results show that changes in purchase timing are a critical determinant of the bias in the sticker shock effect we also show that unaccounted for price response heterogeneity can in itself result in a biased sticker shock parameter however this requires very large differences in price sensitivities across consumers far greater than what is normally observed we develop a hierarchical bayes version of the nested logit model which models heterogeneity via individual level parameters in a continuous random effects framework we estimate the model on scanner panel data from the yogurt and ketchup categories we find in both categories that the 95 probability interval of the posterior distribution of the mean sticker shock coefficient contains the value zero therefore at least for the data used in this study there is no evidence for the sticker shock effect at the aggregate level in contrast the corresponding coefficient from a standard model which ignores this heterogeneity is highly significant and supports the existence of a possibly spurious sticker shock effect consistent with our explanation of the underlying cause of the bias households that are more price sensitive in the choice decision are also found to be more responsive to category promotion activity in their decision to purchase in the category the results highlight the measurement problems associated with imputing reference prices from past prices since the frequency duration and price level of a retailer s promotional program depend on its size and prevalence accurate estimates of the sticker shock effect are essential for formulating optimal promotion strategies an adequate accounting of consumer heterogeneity is critical to this effort

informative advertising and product match abstract this paper studies informative advertising in a variety of market structures for which some consumers are informed about two differentiated products while other consumers are uninformed we characterize a unique symmetric subgame perfect nash equilibrium in advertising and pricing and analyze the welfare properties of the equilibrium remarkably total surplus is non monotonic in advertising in a duopoly market the equilibrium level of advertising may be more or less than socially optimal we also study the effect of a trade association and compare these results with the first best solution and a multiproduct monopolist

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

the outputs of retail activities concepts measurement and evidence from u s census data the authors develop a new economic framework for the empirical analysis of retail margins this framework formalizes the role of distribution services as outputs of retail activities their main results are the following the measures of outputs of retail activities identified in the data perform as important and robust determinants of retail margins variables that purport to capture oligopolistic features of market structure play a limited or no role in determining retail margins quantity setting and price setting under the assumptions of profit maximization and monopolistic competition are categorically rejected by the data the data base is information on 49 retail sectors from the 1982 u s census of retail trades copyright 1993 by mit press

audience characteristics and bundling a hedonic analysis of magazine advertising rates abstract increasingly magazines are able to offer potential advertisers all their readers pure bundling only specific reader segments pure components pricing or a combination of the two mixed bundling using data on advertising rates and reader demographics the authors estimate the implicit prices of reader characteristics within a hedonic framework the results suggest that the magnitude of the price and revenue premiums earned by unbundling a magazine s readers can be substantial

a price discrimination theory of coupons the objective of this paper is to analyze the consumer s decision in electing to use cents off coupons distributed by manufacturers of consumer products arguing that the decision to use coupons is based on the tradeoff between costs of using coupons and the savings obtained it is shown that coupons can serve as a price discrimination device to provide a lower price to a particular segment of consumers based on a price theoretic model it is shown that the users of coupons are more price elastic than nonusers of coupons and that the opportunity cost of time and other household resource variables are determinant factors in consumers decisions implications derived from the model are tested using diary panel data

optimal pricing of new subscription services analysis of a market experiment there are now available a number of new subscription services that comprise a dual pricing system of a monthly access fee rental and a per minute usage charge examples include cellular phones the internet and pay tv the usage and retention of such services depend on the absolute and relative prices of this dual system for instance a moderate access fee but a low usage charge might initially appeal to customers but later a low usage customer might find the monthly fee unjustified and thereby relinquish the service providers of such services therefore usually offer several pricing packages to cater to differing customer needs the purpose of this study is to derive a revenue maximizing strategy for subscription services that is the combination of access and usage price that maximizes revenue over a specified time period an additional objective is to determine access and usage price elasticities because they have historically played an important role in theoretical pricing models the application area is the cellular phone market but for a new rather than an existing product to help gauge the likely usage rates and customer retention a field experiment is conducted in which several alternative price combinations are used specifically a sample of potential residential customers most of whom did not have an existing cell phone were divided into four treatment groups the first group were not charged an access fee but did have to pay a small per minute usage charge the second group also paid a small usage charge but in addition had three access price increases over the duration of the trial the third group paid no access fee but had usage charge increases while the fourth group had both access fee and usage charge increases usage levels for each respondent are recorded as is their month of dropout if they discontinue the service an initial examination of the data shows that higher access fees result in higher customer attrition and higher usage cost results in lower usage furthermore usage and retention are related in that declining usage levels over time often signal impending customer attrition hence two phenomena need to be modeled usage of the service and customer retention conditional on usage some seasonal effects are also observed and are allowed for in the model modeling customer attrition simultaneously with usage is important because ignoring customer attrition will likely result in an underestimate of price sensitivity this results from a censoring effect whereby respondents who remain in the trial tend to be wealthier and hence less price sensitive given the known problems of ignoring customer attrition we develop a theoretical model of usage which explicitly incorporates attrition by extending a time series model introduced by hausman and wise 1979 we make two extensions of the hausman and wise model the first is to generalize it from two to many time periods and the second is to allow for respondent heterogeneity by incorporating latent classes we fit the model by maximum likelihood and find that a two segment model is best in addition we examine the predictive validity of our model and find it to be reasonably good in general the results show that access and usage prices have different relative effects on demand and retention there are five key results first access price has some effect on usage but a much stronger effect on retention second usage price has a strong effect on usage and a moderate effect on retention in that if usage price increases so much that usage declines then lower usage levels results in higher attrition third access price elasticity is about half that of usage price with both elasticities generally being much smaller than 1 indicating relative inelasticity for this particular service fourth customer attrition rate churn is much more sensitive to access than usage price and last if just observed usage is examined and customer attrition is ignored then price sensitivity is very likely to be substantially underestimated on the order of 45 in our case finally when developing the revenue maximizing price combination we allow for the cost of customer acquisition by using some typical advertising to sales ratios for the telecommunications industry we find that the revenue maximizing price is 27 70 per month for the access fee and 0 81 per minute for the airtime charge these values are in line with current access fees and usage costs in the given market

the option value of returns theory and empirical evidence when a firm allows the return of previously purchased merchandise it provides customers with an option that has measurable value whereas the option to return merchandise leads to an increase in gross revenue it also creates additional costs selecting an optimal return policy requires balancing both demand and cost implications in this paper we develop a structural model of a consumer s decision to purchase and return an item that nests extant choice models as a special case the model enables a firm to both measure the value to consumers of the return option and balance the costs and benefits of different return policies we apply the model to a sample of data provided by a mail order catalog company we find considerable variation in the value of returns across customers and categories when the option value is large there are large increases in demand for example the option to return women s footwear is worth an average of more than 15 per purchase to customers and increases average purchase rates by more than 50 we illustrate how the model can be used by a retailer to optimize his return policies across categories and customers

dynamic model of fresh fruit promotion a household production approach many studies consider the dynamic effects of commodity promotion on demand but few derive the theoretical basis for these effects in a model of optimal consumer behavior this study develops a dynamic household production model of u s fresh fruit consumption which it uses to evaluate the effectiveness of advertising and promotion expenditures by the washington apple commission estimates from a dynamic dual generalized leontief system show direct advertising to be marginally more effective than retail promotion in increasing apple sales but advertising has positive spillover effects to sales of other fruits whereas promotion reduces sales of competing products

the price elasticity of selective demand a meta analysis of econometric models of sales the author describes a meta analysis of econometric studies that estimated the elasticity of selective sales or market share to price the literature review yielded 367 suitable price elasticities

selling costs and switching costs explaining retail gasoline margins recent theoretical work has shown that price discrimination can take place in imperfectly competitive as well as monopoly markets the persistence of higher retail margins on unleaded than on leaded gasoline during the 1980s suggests that discrimination may occur even in very competitive markets this article studies a number of cost based explanations for such gasoline pricing as well as the possibility of price discrimination the analysis indicates that gas stations discriminate against groups of customers who are less likely to switch to another station the conclusions highlight the influence of shopping or search costs on pricing decisions even in markets thought to be quite competitive

retailers strategies and food price dynamics evidence from dairy scanner data abstract we investigate the relationship between retailers strategies and dairy price dynamics using high frequency italian scanner data for different dairy products we compute a weekly drift free price index specific for product category chain and type of store exploiting the unbalanced panel data structure to control for unobservable strategies by chain time and type of store we test if unobservables are statistically significant in influencing the price dynamics of each of the products covered by our analysis in general chain and type of store specific unobservables play a significant role moreover we identify the role of some observable strategic variables in controlling or in stimulating price inflation rates we obtain mixed results on the relationship between private label pl market shares and price trend while we find price promotions to be more effective if applied to national brands nbs rather than pls we conclude with some implications for the potential role of public policies in controlling food inflation

economic success factors in spanish small retail businesses an analysis based on sector relative definitions the purpose of this study was to carry out a sectorial analysis of the strategic profile of successful small businesses in spanish retailing first a one dimensional statistical formalisation of the concept of small business was proposed based on yearly sales revenue and relative to the sector likewise some statistical formalisations of the concept of economic success were proposed based on profit margins and also relativised according to sector once a conceptual framework was established a sectorial model of strategic characterisation of successful small retailing firms was developed the results of applying these proposals to the spanish retail industry confirmed the importance of a sectorial approach as opposed to an overall analysis

a simple theory of advertising as a good or bad our analysis treats advertisements and the goods advertised as complements in stable metautility functions and generates new results for advertising by building on and extending the general analysis of complements by assimilating the theory of advertising into the theory of complements we avoid the special approaches to advertising found in many studies that place obstacles in the way of understanding the effects of advertising we also use this approach to evaluate advertising from a welfare perspective whether there is excessive or too little advertising depends on several variables the effects on consumer utility the degree of competition in the market for advertised goods the induced changes in prices and outputs of advertised goods and whether advertising is sold to consumers

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

estimation of an implied price elasticity of demand through current pricing practices researchers have long pursued better methods to estimate price elasticity of market level demand due to a plethora of empirical problems the estimates produced in many empirical studies leave researchers with wide confidence intervals that do little to clarify demand conditions as a result these estimates are of limited practical use to the firm facing a firm level demand here a non statistical methodology based on seller optimization behaviour is applied that creates an implied elasticity of firm level demand that is robust intuitively plausible and free of oppressive data requirements these elasticities are tested in an applied setting against pricing managers surveyed estimates for customer price sensitivity for freight rail transportation services and it is found that the estimate is consistent with their pricing behaviour this methodology is recommended for creating a simple plausible starting point estimate for firm level price elasticities or using this calculation as an input to stat

the influence of serotonin deficiency on choice deferral and the compromise effect abstractpsychological and physiological states such as mood hunger stress and sleep deprivation are known to affect decision making processes and therefore crucially influence consumer behavior a possible biological mechanism underlying the observed variability of consumer behavior is the context sensitive variation in the levels of neuromodulators in the brain in a series of four experimental studies the authors pharmaceutically reduce the levels of the neurotransmitter serotonin in the brain to diminish the availability of subjects cognitive resources in doing so they study how serotonin brain levels influence 1 subjects tendency to avoid buying and 2 consumers preference for product options positioned as a compromise in a given choice set rather than for more extreme alternatives i e the compromise effect using realistic product choice scenarios in a binding decision framework they find that a reduction of brain serotonin levels leads to choice deferral and decreases the compromise

informative advertising in differentiated oligopoly markets abstract this paper examines the welfare implications of informative advertising in differentiated product oligopoly markets the analysis reconciles the conflicting results in previous studies that find advertising to be undersupplied in homogeneous product markets but oversupplied in differentiated product markets when the degree of differentiation is small in equilibrium purely informative advertising is undersupplied when brands are sufficiently close substitutes and oversupplied when brands are more differentiated product differentiation also has welfare implications for the effect of technological change in the advertising sector in response to an advertising cost innovation equilibrium prices fall and the market converges to the socially optimal resource allocation for brands that are sufficiently close substitutes whereas equilibrium prices rise and divergence occurs when brands are more differentiated

patterns in parameters of buyer behavior models generalizing from sparse replication elasticities calculated from estimates of parameters in four consumer behavior system models are pooled in order to assess systematic differences related to variables and to study characteristics the pooling proves to be plausible because the elasticities from particular variable pairings do not vary systematically with study characteristics few elasticities other than those associated with controllable exogenous variables price and distribution differ significantly from the overall mean although the mean elasticity is significantly different from zero the magnitudes of estimated elasticities indicate that the system would tend to converge after being subjected to external shock

changes in organizational structure and shareholder wealth the case of limited partnerships this paper analyzes the consequence for shareholders of a change in organizational form the conversion of a corporation or the spin off of a unit into a limited partnership theory suggests that prior to the tax reform act of 1986 the tax benefits of conversion to a limited partnership and the creation of a new entity separate from the parent corporation should have a positive effect on shareholder wealth on the other hand the increase in agency costs of such an organizational change should decrease the wealth of shareholders empirical results lend support to hypotheses that predict an increase in stock price at the announcement of the conversion but cannot identify the source of the gain

inflation and relative prices a decomposition analysis abstract the variability of relative prices is decomposed into a component due to real effects technical change real income growth and so on and a component due to inflation using quarterly australian data inflation is shown to account for 24 percent of the total relative price variability

tax induced trading of equity securities evidence from the adr market we examine ex dividend date trading of american depositary receipts adrs using a sample of 1 043 dividends over the period 1988 to 1995 adr dividends are often subject to foreign withholding taxes creating incentives for certain investors to avoid the distribution adrs exhibit negative abnormal ex dividend day returns and their prices behave consistently with their related withholding taxes abnormal trading volume for taxable issues exceeds 130 percent and 300 percent of normal volume on the cum and ex dates respectively abnormal volume is an increasing function of foreign withholding tax rates and decreasing function of transactions costs this abnormal exdate trading activity is consistent with tax motivated trading this paper provides empirical evidence from a sample of american depositary receipts adrs that foreign taxes on dividend income are positively associated with abnormal ex dividend day trading activity researchers have long been interested in the question of whether taxes affect investor behavior around ex dividend days such work has implications for corporate financial and distribution policies and for government tax policies adrs provide a unique setting in which to examine the effects of taxes on investor trading behavior because of the unique features of the foreign withholding taxes that apply to them a number of studies have attempted to isolate the determinants of ex dividend day pricing and trading activity of u s equities and there is considerable evidence of tax induced investor behavior around the ex dividend day for common

a model of brand choice and purchase quantity price sensitivities many consumer decisions involve a discrete choice and a continuous outcome examples of such decisions are whether to own a home or rent one and how much to spend which brand of orange juice to buy and how many ounces to buy in cases like these the choice decision is typically modeled separately say using a logit model and the continuous outcomes modeled separately using regression analysis however the continuous outcomes may not be independent of the discrete choice and vice versa and modeling the two decisions independently can lead to inefficient choice parameter estimates and biased and inconsistent regression parameter estimates in this paper we present a methodology from the limited dependent variable literature to model the dependence between the choice and quantity decisions our substantive interest is in the role of price in the choice and quantity decisions when choosing among alternatives we argue that consumers consider prices of all the competitive brands in the quantity decision on the other hand only the price of the chosen alternative is expected to impact how much of the alternative is purchased the analysis of three brands using disaggregate level panel data strongly supports our hypothesis about the role of competitive prices in the choice and quantity decisions

determinants of price elasticities for private labels and national brands of cheese an almost ideal demand system model is developed and used to estimate price elasticities for us cheese sold at retail growing consumption of cheese coupled with fierce competition between private labels and national brands serves as motivating factors for this study per capita consumption of cheese grew by 75 during 1980 2004 and private labels captured a rising share of this growth private labels today account for 35 of market share national brands for the remaining 65 kraft accounts for 45 of national brands but price increases for kraft brands led to a sizeable price gap between its brands and private labels this gap helped to stimulate growth of private labels marketing managers seek to capitalize on both growing cheese sales and price gaps for brands relevant information for marketing managers is consumer sensitivity to price changes this study uses 69 weeks of scanner data with consumers segmented by income levels to derive price elasticities for both lower and higher income consumer

advertising and quality in the u s market for automobiles using data consisting of domestic and foreign automobiles over the period 1985 1990 the hypothesis that advertising serves as a signal of higher quality is empirically tested this is accomplished by examining how advertising levels vary with a quality measure that is not observable at the time of purchase but becomes available subsequent to a model s release above average quality results in expenditures that are 15 higher than average quality outlays lending further support to the signalling hypothesis the positive advertising quality relationship holds strongest when a model significantly improves in quality relative to the previous year s model

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

tax induced trading around ex dividend days abstract this paper investigates trading volume around ex dividend days for taxable distributions cash dividends it is found that trading volume increases significantly around the ex dividend day this increase is more pronounced for high yield actively traded stocks and after brokerage commissions became negotiable the results are consistent with the hypothesis that short term traders have an impact on ex day price behavior at least for taxable distributions for non taxable distributions stock splits and stock dividends we find negative abnormal volume around ex day

the outputs of retail activities french evidence a new economic framework is applied to the empirical analysis of retail margins this framework is founded on the definition of profits and incorporates recent theoretical developments formalizing the role of distribution services as outputs of retail activities the main results are the measures of outputs of retail activities identified in the data perform as important and robust determinants of retail margins variables that purport to capture the oligopolistic features of market structure have little association with the variation in retail margins hypotheses of price setting and quantity setting under the assumptions of profit maximization and monopolistic competition are categorically rejected by the data the data base is information on 50 retail sectors from the 1982 survey of firms in commerce and the 1983 survey of firms in services reported by insee

how dynamic consumer response competitor response company support and company inertia shape long term marketing effectiveness long term marketing effectiveness is a high priority research topic for managers and emerges from the complex interplay among dynamic reactions of several market players this paper introduces restricted policy simulations to distinguish four dynamic forces consumer response competitor response company inertia and company support a rich marketing dataset allows the analysis of price display feature advertising and product line extensions the first finding is that consumer response differs significantly from the net effectiveness of product line extensions price feature and advertising in particular net sales effects are up to five times stronger and longer lasting than consumer response second this difference is not due to competitor response but to company action for tactical actions price and feature it takes the form of inertia as promotions last for several weeks for strategic actions advertising and product line extensions support by other marketing instruments greatly enhances dynamic consumer response this company action negates the postpromotion dip in consumer response and enhances the long term sales benefits of product line extensions feature and advertising therefore managers are urged to evaluate company decision rules for inertia and support when assessing long term marketing effectiveness

dividends taxes and common stock prices the ex dividend day behavior of common stock prices before the income tax this study examines the ex dividend day behavior of common stock prices before the enactment of the federal income tax on ex dividend days during the pre tax period stock prices fell on average by the full amount of the dividend the data are consistent with the hypothesis that i investors in the pre tax period value dividends and capital gains as perfect substitutes and ii the differential taxation of dividends and capital gains has since caused investors to discount the value of taxable cash dividends in relation to capital gains

tax reform and ex dividend day behavior this paper investigates the effect of a major canadian tax reform on the ex dividend day behavior of companies on the toronto stock exchange the results are inconsistent with the hypothesis that price changes on ex dividend days reflect the relative taxation of dividends and capital gains for the representative investor but are consistent with the hypothesis that ex dividend day price behavior reflects short term trading activities

the impact of consumer attentiveness and search costs on firm quality disclosure a competitive analysis firms can invest to disclose quality information about their products to consumers but consumers are not always perfectly attentive to these disclosures indeed technologies such as digital video recorders have increased the ease with which disclosures can be avoided by consumers although such inattention may result in a consumer missing information from one or more competing firms consumers who have missed disclosures might decide to search for quality information to become fully informed before making a purchase decision in this paper we incorporate consumer attentiveness as well as the related endogenous search decision into a model of quality disclosure our results suggest that firms should disclose less quality information as the share of partially informed consumers informed about one firm but not the other increases or as consumer search costs increase we also provide insights into the potential impact of consumer trends toward lower attentiveness and lower search costs this paper was

personal selling elasticities a meta analysis abstract this article presents a meta analysis of prior econometric estimates of personal selling elasticity that is the ratio of the percentage change in an objective ratio scaled measure of sales output e g dollar or unit purchases to the corresponding percentage change in an objective ratio scaled measure of personal selling input e g dollar expenditures the authors conduct a meta analysis of 506 personal selling elasticity estimates drawn from analyses of 88 empirical data sets across 75 previous articles they find a mean estimate of current period personal selling elasticity of 34 they also find that elasticity estimates are higher for early life cycle stage offerings higher from studies set in europe than from those set in the united states and smaller in more recent years in addition elasticity estimates are affected significantly by analysts use of relative rather than absolute sales output measures by cross sectional rather than panel data by omission of promotions by lagge

relative price variability in the united states abstract following the clements nguyen methodology relative price variability in the united states is decomposed into the components due to real factors inflation and their interaction overall inflation accounts for about half of relative price variability but its share is the largest during 1973 1980 and the smallest during 1981 1986 cross commodity distribution of relative price variability shows rather dramatic changes

relation between inflation and relative price variability in the united states evidence from data for the 1980s abstract monthly cpi data for 1967 1986 in respect of 10 major categories are utilized the most significant result is a strongly negative association between relative price variability and inflation as well as its expected and unexpected components during the 1980s variations in the estimated coefficients for the three subperiods studied also seem interesting

inflation and relative prices a system wide approach abstract the paper introduces a system wide model for the analysis of the effects of inflation on relative prices this enables the identification of those commodities whose relative prices are distorted by inflation the model provides measures of the natural rate of relative price variability which is associated with zero inflation and the inflation rate which minimizes relative price variability an illustrative application with australian data is provided

a model of retail formats based on consumers economizing on shopping time retailers in developed countries increasingly provide one stop shopping why are they responding to growing demand for time saving convenience or are they responding to economies of scale made possible by new retail technology and what role if any is played by improvements in automotive refrigeration and other consumer technology to examine these questions we develop a model that can help explain the growth of one stop shopping estimate the model with aggregate grocery retail data and compare the implications of our model with competing explanations our model includes several desirable features 1 the extent of one shop shopping is endogenously determined 2 consumer store choice is determined in an explicit household production utility maximizing context this choice is based on a tradeoff between time saving shopping convenience and price 3 the model is readily amenable to empirical testing the key endogenous parameter of our model describes the number of categories carried by a store in the context of grocery retailing this parameter can distinguish between a single category specialty store a simple grocer a supermarket and a large superstore this parameter is determined by the interplay of consumers economizing on shopping time and retail competition in the presence of technological constraints which relate operating cost with assortment size our approach may also be viewed as an example of how the boundary between retail service production and household service production can be modeled as a market outcome in the spirit of betancourt and gautchi betancourt roger david gautschi 1990 demand complementarities household production and retail assortments marketing sci 92 spring 146 161 and wernerfelt wernerfelt birger 1994 an efficiency criterion for marketing design j marketing res 31november 462 470 the nature of extant retail formats and other channel related institutions circumscribes the boundary between retailers and households with the notable early exception of baumol and ide baumol william j edward a ide 1956 variety in retailing management sci 31 october 93 101 few explicit models describe retail format determination as an equilibrating market mechanism our model describes the determination of one aspect of retail formats namely the extent of one stop shopping our hope is that similar approaches can be used to describe other aspects and types of emergent retail formats we estimate our model using u s aggregate annual data for a 26 year period and later corroborate parts of the analysis using cross sectional data for the 48 contiguous states of the u s the equilibrium conditions of our model translate into a system of two equations with two endogenous variables estimates of the reduced form parameters provide our central empirical finding that per capita disposable income has had a significant positive effect on both supermarket assortment as expected from our model and store operating costs perhaps somewhat less expected this suggests that greater prevalence of one stop shopping has been a response to growing demand for time saving convenience the estimates of the underlying structural parameters also provide a measure of the imputed net savings to consumers from supermarket shopping taking into account reductions in shopping time made possible by supermarkets savings equivalent to approximately 2 2 of expenditures on grocery products over the 1961 1986 period we lastly consider competing hypotheses while a number of explanations can account for increased store assortment these explanations have divergent implications for retail margins operating costs and profits these implications suggest that retail scale economies were not the drivers of one stop shopping in the years of our data nor was the impetus to increase store size primarily a desire to bring in new higher margin items however we acknowledge that transportation and inventory holding technologies are prerequisites to one stop shopping and that improvements in these technologies were particularly important in the early growth period of supermarkets

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

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

detailing vs direct to consumer advertising in the prescription pharmaceutical industry the pharmaceutical industry has always used sales representatives to target physicians detailing who are a key link in sales and market share for prescription pharmaceuticals since august of 1997 when the food and drug administration eased the restrictions on direct to consumer advertising dtca there has been a dramatic increase in the use of dtca by pharmaceutical firms to target end customers patients dtca seems to have two different effects on pharmaceutical markets the first is to inform patients about the availability of drugs for some ailments thus expanding the market constructive the second is to persuade patients to talk about specific brands when they meet physicians with the objective of influencing market share combative we consider both effects of dtca in the presence of a detailing program in a competitive environment we incorporate the dynamics of physician patient interaction in a game theoretic model where firms decide on the form of dtca to adopt constructive or combative and then compete in the marketplace by choosing detailing and dtca levels we answer four questions what is the impact of adopting dtca on competitive intensity how do optimal detailing levels for a firm change with the adoption of dtca how should the dtca strategy for a firm vary depending on whether it is stronger or weaker in its degree of influence in the physician s office finally under what conditions would competing firms voluntarily decide to pursue constructive dtca

lowering customer evaluation costs product differentiation and price competition when match uncertainty is resolved via costly evaluation the first product sampled by a customer is more likely to make the sale this prompts firms to lower their products evaluation costs to attract customers to sample their products first such efforts by firms are called customer learning investment cli when product quality is freely observable but horizontal match is not we examine how cli choices interact with quality and price competition in a duopoly cli has a competition effect in that a higher cli of a firm increases its demand but decreases that of its rivals in the market covered duopoly both qualities will decrease increase when the high end low end firm invests more in customer learning and remain unchanged when they invest equally relative to when neither firm invests we further show that the firm with a higher relative production efficiency invests more in customer learning than the competitor in the market not covered duopoly cli by the low end firm also creates a market

an examination of ex dividend day stock price movements the case of nontaxable master limited partnership distributions this study examines the unit stock price and volume behavior of master limited partnerships mlp around the ex dividend day since the dividends of mlps are not taxable to the unitholder tax based hypotheses predict no abnormal unit movements around the ex day significant positive excess returns and volume are found before the ex dividend day and significant negative excess returns are found on the ex dividend day the findings which are not significantly impacted by the tax reform act of 1986 suggest ex day stock movements are not solely a function of investor marginal tax rates or corporate trading behavior elton and gruber s 1970 findings that in 1966 67 stock prices fell on average by less than the amount of the dividend on the ex dividend date and that the ratio of the price decrease to the dividend was correlated with the dividend yield have led to the development of a tax clientele hypothesis relating to investor behavior one puzzling result from their study was the finding that the price decreases for the highest yielding securities were significantly greater than the dividends which in their analysis implied an investor clientele with negative tax rates while michaely 1989 using 1986 87 data was unable to find support for the tax clientele hypothesis across different yield groups he also documented the large price drop for the highest yielding securities michaely 1989 suggested that his results may demonstrate a preference of corporations for dividend over capital gains because of favorable tax treatment corporations receive on dividend income corporate trader hypothesis shefrin and statman 1984 however suggest that preferences for dividends over capital gains may exist for nontax reasons such as self control or a desire to segregate gains and losses the purpose of this paper is to examine the ex dividend day stock price behavior of master limited partnership mlp units during the 1985 88 period dividends from these high yielding securities are not taxable therefore support for either the tax clientele hypothesis or the corporate trader hypothesis would be found only if the average ex day price change on mlps equalled the dividend this result would also be consistent with barclay s 1987 finding that before the enactment of an income tax in 1913 even high

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

chapter 11 pricing models in marketing publisher summary this chapter brings together a set of diverse efforts in the recent literature on the modeling of price decisions and related questions in marketing there has been an impressive growth in the array of topics investigated in the literature various trends in the development of pricing models are evident from the foregoing review first one trend has been to develop theoretical models to describe observed pricing strategies in the marketplace and to derive conditions under which certain strategies are optimal this trend is clearly evident when one considers the area of dynamic pricing models another trend is an attempt to develop pricing models in which certain aspects of consumer behavior e g asymmetric response to price increases versus price decreases are incorporated this development is quite recent and does offer a large potential a third dominant direction is the use of game theoretic models for developing equilibrium pricing strategies

the marketing mix decision under uncertainty this paper develops a marketing mix model under uncertainty using the capital asset pricing model capm valuation framework the model is general because it treats price advertising and personal selling simultaneously and allows for general patterns of uncertainty because the manager often lacks precise quantitative information about the sales response function the analysis focuses on the qualitative properties of the model the methodology of comparative statics is used to determine how the marketing mix should be modified when market conditions change specifically the comparative statics are shown to depend on how advertising and personal selling influence price sensitivity the interaction between advertising and personal selling and the relationship between sales and the return earned in the capital markets the comparative statics for risk depend in addition on the precise mathematical form with which uncertainty enters the random demand function i e additive multiplicative or generalize

effects of wholesaler concentration on retailers by format evidence from japanese brand level price data using unique brand level wholesale price data this article examines how purchase prices of commodities for retailers are influenced by wholesale concentration compared with studies focusing on retail prices little empirical work has measured the impact of wholesale concentration on wholesale prices economic theory suggests that the sensitivity of purchase price in response to degree of wholesale concentration is smaller for large retail formats than for small retail formats in the presence of intra format retail competition to test the validity of the theoretical implication i measure the impact of the concentration on purchasing prices for retailers by format empirical findings support the hypothesis that the large retail format tends to draw advantageous purchase prices when wholesalers become increasingly oligopolistic

going where the ad leads you on high advertised prices and searching where to buy an important role of informative advertising is to inform consumers of the simple fact that the shop that advertises sells a particular product this information may help consumers to save on their search activities instead of wandering around a consumer can simply visit the shop that has advertised knowing that there he can find the commodity he is looking for the implications of this simple fact have not been studied before using game theoretic reasoning in a model that combines consumer search and firms advertising we show that firms may find it optimal to advertise prices that are higher than nonadvertised prices the important mechanism underlying this result is that advertising lowers the expected search cost for consumers through this analysis we provide a new insight into the role of informative advertising

cross national laws and differences in market response international differences in general and cultural differences in particular exert profound influence on what people buy in modeling market response highly visible international differences in purchase behavior seem to lead to an assumption by management scientists that there are large parallel international differences in market response to such things as price and advertising in an interpretive review of market response models we do find international differences in response parameters but we also find that parameter differences due to cross national factors tend to be smaller than differences related to technical characteristics of the model or to product market specifics we suggest two new intermediate categories of generalizability between the extremes of everything is the same and everything is different we also argue that one promising approach to international generalization is through appropriate statistical adjustment of parameters from existing models

the ability to compensate for suboptimal capacity decisions by optimal pricing decisions abstract certain companies have high capacity cost and rather moderate production cost these companies usually assume that deciding about their capacity is quite critical frequently however they are able to adjust the demand for their products to the available capacity by setting appropriate prices that is higher lower than current prices in the presence of under capacity over capacity we argue that appropriate prices can reduce the adverse effects of non optimal capacities we analyze the sensitivity of profit in such a situation for a company in a monopolistic market selling a non storable product and facing fluctuating but interdependent demand across two time periods which allows to profitably differentiate prices therefore we state optimality conditions for prices in situations of variable and given capacities and describe a procedure to determine them the main suggestion of this analysis is that within the bounds of the normative models and specific parameters examined optimal prices can substantially reduce the adverse effects of capacity deviating from its optimum in this way profit is rather insensitive to deviations of capacity from its optimum the implications of this finding are discussed for a number of situations

taxes and corporate policies evidence from a quasi natural experiment we document important interactions between tax incentives and corporate policies using a quasi natural experiment provided by a surprise announcement that imposed corporate taxes on a group of canadian publicly traded firms the announcement caused a dramatic decrease in value prospective tax shields partially offset the losses adding 4 6 to firm value on average and vary with the tax status of the marginal investor further firms adjust leverage payout cash holdings and investment in response to changing tax incentives overall the event study and time series evidence supports the view that taxes are important for corporate decision making
