a dynamic model of brand choice when price and advertising signal product quality in this paper we develop a structural model of household behavior in an environment where there is uncertainty about brand attributes and both prices and advertising signal brand quality four quality signaling mechanisms are at work 1 price signals quality 2 advertising frequency signals quality 3 advertising content provides direct but noisy information about quality and 4 use experience provides direct but noisy information about quality we estimate our proposed model using scanner panel data on ketchup if price is important as a signal of brand quality then frequent price promotion may have the unintended consequence of reducing brand equity we use our estimated model to measure the importance of such effects our results imply that price is an important quality signaling mechanism and that frequent price cuts can have significant adverse effects on brand equity the role of advertising frequency in signaling quality is also significant but it is less quantitatively important than price in the printed version of marketing science vol 27 no 6 erdem et al 2008 was mistakenly identified as a research note it is a regular article and has been corrected here and in the online table of contents

behavioral demand effects when buyers anticipate inventory shortages abstract firms often worry about how buyers will react when there is an inventory shortage but the anticipation of facing a shortage may also impact buyer behavior in this paper we use a combination of theoretical modeling computational methods and laboratory experiments to understand buyers search behavior in markets where there is potential for either a costly or costless inventory shortage when inventory shortages are costly to buyers we find their equilibrium purchasing strategy generates a newsvendor problem among the firms in turn experimental data suggests buyer behavior can be explained by prospect theory better than by standard assumptions of fully rational expected utility maximizing agents indicating that potential inventory shortages generate loss aversion among buyers and there is systematic mis identification of the probability with which they will be able to procure an item using computational methods we find firms are able to extract more surplus from behavioral buyers via higher prices than would be predicted by the standard model on the other hand when inventory shortages are not costly to buyers the effect of behavioral biases on the part of buyers is not relevant but in this case there can be a benefit to reducing inventory via a reduction in price competition

optimal joint pricing and lot sizing with fixed and variable capacity this paper examines previously unexplored fixed and variable capacity problems of jointly determining an item s price and lot size for a profit maximizing firm facing constant but price dependent demands over a planning horizon we apply geometric programming to these constrained nonlinear maximization problems with nonconcave objective functions and obtain global optimal solutions using kuhn tucker condition marginal and sensitivity analyses we investigate model interactions provide managerial implications on the optimal capacity decisions and explore the postoptimal behavior of the price lot size and capacity expansion and reduction size some findings cast interesting insights different from previous just in time management studies without pricing consideration

pricing and lot sizing decisions for perishable goods when demand depends on selling price reference price product freshness and displayed stocks abstract price is an important factor affecting demand rate based on economic and marketing theory in addition today s health conscious consumers prefer a product further from its expiration date because it is fresher and can be stored longer furthermore a large display of goods in a supermarket induces customers to buy more due to its visibility variety and seasonality as a result we develop a joint pricing and lot sizing model for retailers selling perishable products in which the demand depends on not only the selling price and reference price but also the product freshness linked to expiration date and displayed stock level we then formulate the problem as a deterministic model in which the retailer determines the optimal selling prices and ending inventory levels to maximize the discounted total profit furthermore we discuss the retailer s optimal decisions under two scenarios of demand behavior loss neutrality and loss aversion our theoretical analysis shows that the optimal pricing and ending inventory level strategies are both monotonic in time and the equilibrium of the system is unique for these two scenarios of demand behavior finally a set of structural properties and sensitivity analysis is also developed to characterize the impacts of model parameters on the optimal decisions

pricing and lot sizing polices for perishable goods when the demand depends on selling price displayed stocks and expiration date abstract price is a major factor on the demand based on marketing and economic theory in addition the demand for perishable products also depends on its freshness moreover it is a well known fact that increasing stock display e g fresh fruits vegetables baked goods may encourage consumers to purchase more this paper first proposes an inventory model that stipulates the demand explicitly in a multivariate function of price freshness and displayed stocks it may be profitable to have a closeout sale at a markdown price and always keep on hand displayed stocks fresh and plentiful if the demand is freshness and stock dependent hence the traditional assumption of zero ending inventories is relaxed to a non zero ending inventory as a result the objective is to determine three decision variables i e unit price cycle time and ending inventory level in order to maximize the total profit then it is demonstrated that the total profit is strictly pseudo concave in those three decision variables which reduces the search for solutions to a unique local maximum finally numerical examples to illustrate the theoretical results and to highlight managerial insights are presented

the role of price in multi attribute product evaluations the potentially multifaceted role of price in product evaluations is investigated with an empirical analysis of surveyed beliefs attitudes and intentions regarding automobile brands it is found that price beliefs both influence and are influenced by beliefs about a brand s quality thereby contributing to the attribution definition process however price is not a significant determinant of overall attitude it is also found that price becomes a negative factor when behavioral intentions are involved lending support to an economic interpretation of price

oil prices and the stock prices of alternative energy companies energy security issues coupled with increased concern over the natural environment are driving factors behind oil price movements while it is widely accepted that rising oil prices are good for the financial performance of alternative energy companies there has been relatively little statistical work done to measure just how sensitive the financial performance of alternative energy companies are to changes in oil prices in this paper a four variable vector autoregression model is developed and estimated in order to investigate the empirical relationship between alternative energy stock prices technology stock prices oil prices and interest rates our results show technology stock prices and oil prices each individually granger cause the stock prices of alternative energy companies simulation results show that a shock to technology stock prices has a larger impact on alternative energy stock prices than does a shock to oil prices these results should be of use to investors managers and policy makers

optimal retailer investments in green operations and preservation technology for deteriorating items abstract this paper examines the impact of dynamic retailer investments in green operations while considering the reference price effect a replenishment problem based on joint pricing dynamic investment in green operations preservation technology and optimal replenishment times for deteriorating items is considered as a way to maximize retailer profit in this problem the demand rate depends on the sales and reference prices as well as green concern level optimal control theory is employed to obtain a dynamic investment rate and a simulated annealing algorithm is used to find the solution of the nonlinear constraint optimization problem which determines the price preservation technology investment and replenishment cycle time in addition computational simulations and sensitivity analyses are carried out to offer managerial insights the findings suggest that continuous investment in green operations and preservation technology can significantly improve the retailer s financial performance the consumer reference price is an important influence on the retailer s decision to invest in green operations furthermore results show that the higher price sensitivity of the market always discourages the retailer from investing in green operations the retailer needs to invest more in green operations for products with relatively high unit value

optimal dynamic pricing for deteriorating items with reference price effects when inventories stimulate demand abstract in this paper we incorporate reference price effects into a deteriorating inventory problem when the demand rate depends on displayed stock level and selling price simultaneously reference price effects are formed empirically by customers to adjust current price perception on the basis of past purchases the market demand is assumed to be responsive to the difference between the current selling price and the reference price which is perceived as a loss or a gain we consider three scenarios of market demand loss neutrality loss aversion and loss seeking an optimal dynamic pricing model is established to determine a pricing strategy maximizing the discounted total profit over an infinite time horizon theoretical results are derived to demonstrate the existence of the optimal solutions and to explore the relationships between optimal pricing decisions and an initial reference price based on mild assumptions numerical example and sensitivity analysis are presented to illustrate the theoretical results and managerial insights finally concluding remarks are offered

technical note intertemporal price discrimination via reference price effects we consider the dynamic pricing problem a monopolistic seller faces when customers arrive in heterogeneous time periods and their purchase decisions are affected by reference prices formed from their past observations of prices we illustrate that a new form of price discrimination opportunity exists in such situations where the seller s optimal pricing strategy is a cyclic one even when the customers are loss neutral and their demand functions are identical this result differs from those of prior studies where the optimal price paths are shown to be asymptotically constant and thus is unique due to the interaction between the heterogeneous arrivals and the reference price effects we also provide the cycle length of the optimal pricing policy when the demand function is linear and when customers are loss neutral in this era when customer information is easier accessible our results suggest the sellers consider this new dimension of price discrimination in conjunction with the old ones to take advan

dynamic control of a monopolist s product and process innovation with reference quality our main purpose is to investigate the dynamic control problem of a monopolist s product and process innovation under reference quality the main features of this article are i a monopolist deal

optimal pricing policy in the presence of experience effects i introduction in this paper we analyze the problem of optimal intertemporal pricing for a monopolist when cur rent and past output affect future cost and or demand conditions through experience in production and or in consumption learning by doing the experience curve contagion habit formation bandwagon and snob effects are all examples of terminologies used to describe such situations we call these experience effects for convenience and explore profit maximizing pricing behavior when such effects exist in the traditional profit maximization model a firm chooses the price output combination so as to maximize short run i e current profits the familiar mc mr equality given that price is higher than average variable cost and a nonbind ing capacity constraint is a necessary condition for price takers as well as price makers this as sumes that the current pricing decision has no bearing on the future so that long run profit is maximized by a series of short run maximizing

dynamic pricing strategies with reference effects we consider the dynamic pricing problem of a monopolist firm in a market with repeated interactions where demand is sensitive to the firm s pricing history consumers have memory and are prone to human decision making biases and cognitive limitations as the firm manipulates prices consumers form a reference price that adjusts as an anchoring standard based on price perceptions purchase decisions are made by assessing prices as discounts or surcharges relative to the reference price in the spirit of prospect theory we prove that optimal pricing policies induce a perception of monotonic prices whereby consumers always perceive a discount respectively surcharge relative to their expectations the effect is that of a skimming or penetration strategy the firm s optimal pricing path is monotonic on the long run but not necessarily at the introductory stage if consumers are loss averse we show that optimal prices converge to a constant steady state price characterized by a simple implicit equation otherwise the optimal policy cycles the range of steady states is wider the more loss averse consumers are steady state prices decrease with the strength of the reference effect and with customers memory all else equal offering lower prices to frequent customers may be suboptimal however if these are less sensitive to price changes than occasional buyers if managers ignore such long term implications of their pricing strategy the model indicates that they will systematically price too low and lose revenue our results hold under very general reference dependent demand models

health and agricultural productivity evidence from zambia we evaluate the productivity effects of investment in preventive health technology through a randomized controlled trial in rural zambia in the experiment access to subsidized bed nets was randomly assigned at the community level 516 farmers were followed over a one year farming period we find large positive effects of preventative health investment on productivity among farmers provided with access to free nets harvest value increased by us 76 corresponding to about 14 7 of the average output value while only limited information was collected on farming inputs shifts in the extensive and the intensive margins of labor supply appear to be the most likely mechanism underlying the productivity improvements observed

dynamic quality policies with reference quality effects abstractdynamic pricing policies with reference price demand have been intensely analysed less studied are dynamic quality policies with reference quality demand this article studies the dynamic quality policy of a firm whose consumers use a reference point in their decision making in line with the principles of behavioural economics more specifically i consider reference quality formation in an optimal control setting by solving on the basis of pontryagin s maximum principle i obtain analytical solutions to the optimal quality policy the managerial implications of quality reference for dynamic quality policy are discussed

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

are markets with loss averse consumers more sensitive to losses behavioral pricing and revenue management aim to incorporate realistic consumer behavior into firms pricing and inventory models the key input to these models is market demand which is often assumed to inherit the characteristics of consumer behavior as when for example one assumes that a market consisting of loss averse consumers is more responsive to losses than to gains yet market demand and consumer behavior need not be related and so we argue that approach to modeling market demand is misguided this paper proposes an approach that accounts for the heterogeneity in consumer valuation we aggregate the demand of individual loss averse consumers to obtain market demand and show that market demand may be more responsive to gains or losses or it may be equally responsive our results have profound implications not only for how best to characterize the market demand of behaviorally biased consumers but also for determining the firm s optimal pricing policy this paper was accepted by serguei net

agricultural non wage production and health status a case study in a tropical environment abstract to date it has rarely been possible to assess the effect of health status on the productivity of agricultural workers particularly among non wage earning peasants in this paper the author uses observations gathered in the course of four successive inquiries among rice growers working on one of the major programmes of agricultural development undertaken in the cameroons two groups of rice growers were identified and studied separately the estimation of a production function on pooled cross section and time series observations makes it possible to measure the influence of health status on paddy output a 10 percent reduction in the incidence of urinary bilharziasis could result in a 4 percent increase in production

strategic decentralization in channels the purpose of this paper is to understand the effect of strategic interaction on a manufacturer s channel structure decision in the model i analyze if there were no strategic interaction then the manufacturer would prefer vertical integration to decentralization with strategic interaction however decentralization can be a nash equilibrium strategy as mcguire and staein mcguire timothy richard staelin 1983a an industry equilibrium analysis of downstream vertical integration marketing sci 2spring 161 192 showed so the question arises what is it about strategic interaction that makes decentralization a nash equilibrium strategy the answer i give is that strategic interaction makes it possible for a manufacturer s retail demand curve to rise when he decentralizes i show that this raising of the demand curve on decentralization can happen only if one of the following mutually exclusive conditions is satisfied 1 the manufacturers products are demand substitutes at the retail level and strategic complements at the manufacturer or retailer levels 2 the manufacturer s products are demand complements at the retail level and strategic substitutes at the manufacturer or retailer levels strategic complementarity at the retailer manufacturer level means that if one retailer manufacturer raises his price then the other retailer manufacturer would raise his price as well strategic substitutability is just the opposite these results show that what is important for decentralization to occur is not how demand substitutable the two manufacturers products are as one might have thought from earlier works in the literature but rather the nature of coupling between demand dependence and strategic dependence

incorporating reference price effects into a theory of consumer choice although there has been a good deal of research on incorporating the effects of reference price formation into empirical models of consumer buying behavior little formal theoretical work had been undertaken to date this paper incorporates reference price effects into the traditional economic theory of consumer choice and examines the effects of reference price formation on the results of the traditional theory its marketing implications and the implications for empirical models which examine the effects of reference price formation on actual consumer behavior several implications of the theoretical model are empirically tested using weekly retail egg sales data from southern california this analysis indicates that reference price formation does have significant effects on consumer behavior furthermore these effects are asymmetric with consumers two and a half times more responsive to egg price increases that are in excess of the reference price than they are to comparable egg price decreases

dynamic stochastic inventory management with reference price effects we analyze the joint inventory and pricing decisions of a firm when demand depends on not only the current selling price but also a memory based reference price and customers are loss averse the presence of reference price effect leads to a nonconcave one period expected revenue in price and reference price we introduce a transformation technique that allows us to prove under some mild assumptions the optimality of a reference price dependent base stock list price policy which is characterized by a base stock level and a target reference price in addition we show that the target reference price is increasing in the reference price but except in the loss neutral case the base stock level is not monotone in the reference price we also show that in the steady state of the model with the reference price effect the optimal price is lower while the optimal base stock level is higher than their counterparts in the model without the reference price effect

how do the stock prices of new energy and fossil fuel companies correlate evidence from china abstract this study documents the return and volatility spillover effect between the stock prices of chinese new energy and fossil fuel companies using the asymmetric bekk model based on daily samples taken from august 30 2006 to september 11 2012 the dynamics of new energy fossil fuel stock spillover are found to be significant and asymmetric compared with positive news negative news about new energy and fossil fuel stock returns leads to larger return changes in their counter assets news about both new energy and fossil fuel stock returns spills over into variances of their counter assets and the volatility spillovers depend complexly on the respective signs of the return shocks of each asset the empirical results demonstrate that new energy and fossil fuel stocks are generally viewed as competing assets that positive news about new energy stocks could affect the attractiveness of fossil fuel stocks and that new energy stock investment is more speculative and riskier than fossil fuel stock investment these results have potential implications for asset allocation financial risk management and energy policymaking

network connectedness of green bonds and asset classes abstract we identify network connectedness between green bonds and different asset classes over different investment horizons in the eu and us asset markets we first focus on dynamic correlations between green bond and asset class price changes in different time scales on the basis of wavelet coherence we then identify network connectedness by decomposing time series into different frequency components in each of which we evaluate connectedness on the basis of the error variance decomposition of a multivariate vector autoregressive model our empirical evidence reveals strong connectedness between green bonds and treasury and corporate bonds in the short and long run and in both the eu and the usa with green bonds receiving sizeable spillovers from treasury and corporate bond prices and transmitting negligible effects likewise we find that green bonds are weakly connected with high yield corporate bond stock and energy assets over different time scales these findings have implications for green bond investors regarding portfolio design and hedging decisions and for the channelling of financial flows to economic activities that are consistent with a decarbonized economy

environmental expenditure spillovers evidence from an estimated multi area dsge model abstract this article constructs and estimates a multi area dynamic stochastic general equilibrium model with a spatial simultaneous equation taking beijing tianjin hebei region in china as an example we explain the dynamic effect of environmental expenditure shock and its spillover effects environmental expenditure has an obvious crowding out effect on consumption and investment in local area but has some positive influences on the economy of external regions over the business cycle environmental expenditure shock in local area can well explain the volatility of real output and social investment in the last 52 quarters however environmental expenditure shocks in external regions have little contribution to the volatility of output and investment in local area one interesting result is that the contribution of environmental expenditure shocks in external regions to the trend of pollution fluctuation is greater than that in local area

multiattribute loss aversion and reference dependence evidence from the performing arts industry we study the prevalence of multiattribute loss aversion and reference effects in a revenue management setting based on data of individual level purchases over a series of concert performances the reference dependence that drives consumer choice is not only based on the price but also on observed sales as a fraction of the seating capacity during their past visits we find that consumers suffer from loss aversion on both prices and seats sold consumers incur significant utility loss when prices are above their references or when the actual seat sales are lower than their references we suggest pricing policies that can address consumer decisions driven by such reference dependence and loss aversion this paper was accepted by vishal gaur operations management

price coordination in distribution channels a dynamic perspective abstract in this study we investigate two important questions related to dynamic pricing in distribution channels i are coordinated pricing decisions efficient in a context where prices have carry over effects on demand ii should firms practice a skimming or a penetration strategy if they choose to coordinate or to decentralize their activities to answer these questions we consider a differential game that takes place in a bilateral monopoly where the past retail prices paid by consumers contribute to the building of a reference price the latter is used by consumers as a benchmark to evaluate the value of the product and by firms to decide whether to adopt a skimming or a penetration strategy we then compute and compare strategies total channel profits and individual profits under vertical integration and decentralization at steady state and along the optimal time paths one of our main findings states that for some values of the initial reference price there is a time interval where channel decentralization performs better than coordination during this transition period at least one of the channel members could be tempted to end his cooperation especially if he is not farsighted and if there are no binding agreements with the other channel partners

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

technical note a note on optimal strategic pricing of technological innovations the experience curve phenomenon of falling marginal costs associated with accumulated output or production experience has given rise to dynamic pricing models optimal pricing policies will depend upon the nature of the dynamic demand and cost functions in this note we shall show that the demand function employed by bass bass f m 1980 the relationship between diffusion rates experience curves and demand elasticities for consumer durable technological innovations j bus 53 july s51 s67 when taken in conjunction with the experience curve cost function leads to a multiperiod pricing strategy which is always less than the myopically optimal price further we present a dynamic programming algorithm for the multiperiod strategy in which we have explored the effects on discounted profits of myopic pricing versus multiperiod pricing the results of this comparison may to some be somewhat surprising and may have managerial significance

oil shocks and their impact on energy related stocks in china abstract this paper contributes to the current literature by adopting time varying conditional correlation and asset pricing models to discover how the dynamics of international oil prices affect energy related stock returns in china after conditioning for structural instability the results show a much stronger relation following the 2008 financial crisis we argue that this reflects the fact that investors in the chinese stock market especially for energy related stocks are more sensitive to the shocks in international crude oil market

dynamic duopolistic competition with sticky prices the authors study duopolistic competition in a homogeneous good through time under the assumption that its current desirability is an exponentially weighted function of accumulated past consumption this implies that the current price of the good does not decline by as much to accommodate any given level of current consumption our an alysis is conducted in terms of a differential game it is found that the equilibrium price corresponding to the open loop nash equilibriu m strategies approaches the static cournot equilibrium price while th e equilibrium price corresponding to the closed loop nash equilibrium strategies which are subgame perfect approaches a price below it copyright 1987 by the econometric society

clearance pricing and inventory policies for retail chains clearance pricing and end of season inventory management are challenging and important problems in retailing sales rates depend upon price seasonal effects and the remaining assortment of items available to customers there is little time to react to observed sales and pricing errors result in either loss of potential revenue or excess inventory to be liquidated this paper develops optimal clearance prices and inventory management policies that take into account the impact of reduced assortment and seasonal changes on sales rates versions of these policies have been tested and implemented at three major retail chains and these applications are summarized and discussed

a differential game design of watershed pollution management under ecological compensation criterion abstract the watershed ecological compensation is used as a policy instrument in china in order to reduce water pollution and attain watershed sustainability in this paper we construct a differential game between a local government and a profit maximizing local firm with one competitor in a watershed ecological compensation system then the optimal dynamic strategy is obtained by applying maximum principle finally we investigate the influence of shadow prices on control variables and firm s output in three different cases this study focuses on how to reach a balance between the sustainable development of local economy and the effective protection of water resources from an ecological perspective for the local government as well as on how to maximize the profit of the local firm in an ecological compensation system

wavelet based test of co movement and causality between oil and renewable energy stock prices abstract we studied co movement and causality between oil and renewable energy stock prices using continuous and discrete wavelets firstly to obtain information on dynamic correlations over time and for different time scales from wavelet coherence and secondly to obtain information on linear and non linear granger causality in the time frequency domain for general and sectoral renewable energy indices for the period 2006 2015 our findings indicate that dependence between oil and renewable energy returns in the short run was weak but gradually strengthened towards the long run mainly for the period 2008 2012 our causality tests provide evidence against linear causality at higher frequencies and in favour of unidirectional and bidirectional linear causality at lower frequencies in contrast we found consistent evidence of non linear causality running from renewable energy indices to oil prices at different time horizons and mixed evidence of causality running from oil to renewable energy prices these results have potential implications for investors in terms of hedging and for policymakers in terms of policy support decisions regarding the development of renewable energy

a comparative analysis of reference price models the effect of reference price on brand choice decisions has been well documented in the literature researchers however have differed in their conceptualizations and therefore in their modeling of reference price in this article we evaluate five alternative models of reference price of which two are stimulus based i e based on information available at the point of purchase and three that are memory based i e based on price history and or other contextual factors we calibrate the models using scanner panel data for peanut butter liquid detergent ground coffee and tissue to account for heterogeneity in model parameters we employ a latent class approach and select the best segmentation scheme for each model the best model of reference price is then selected on the basis of fit and prediction as well as on the basis of parsimony in cases where the fits of the models are not very different in all four categories we find that the best reference price model is a memory based model namely one that is based on the brand s own price history in the liquid detergent category however we find that one of the stimulus based models namely the current price of a previously chosen brand also performs fairly well we discuss the implications of these findings

green bond and financial markets co movement diversification and price spillover effects abstract we examine co movement between the green bond and financial markets finding that the green bond market couples with corporate and treasury bond markets and weakly co moves with stock and energy commodity markets we also find that green bonds have negligible diversification benefits for investors in corporate and treasury markets whereas diversification benefits are sizeable for investors in stock and energy markets we further confirm that green bonds are affected by substantial price spillovers from corporate and treasury fixed income markets and that large price swings in stock and energy markets have a negligible impact on green bond prices

green supply chain performance with cost learning and operational inefficiency effects environmental issues are receiving significant attention from the public accelerating the development of green supply chain in operations management this study focuses on the green supply chain performance in a single manufacturer retailer setup in which the manufacturer determines energy efficiency level and wholesale price while the retailer decides on sales price the unit production cost is jointly affected by cost learning and operational inefficiency effects open loop feedback and myopic equilibria are subsequently derived and the corresponding supply chain performance and profit distribution are analyzed the main results show that forward looking behavior is preferred to myopic one for channel members feedback equilibrium is beneficial to the manufacturer but is harmful to the retailer the supply chain efficiencies in forward looking and myopic situations are lower than the static supply chain efficiency which results from cost learning and operational inefficiency effects as well as non price variable the manufacturer and the retailer extract more profits under certain conditions i e high cost learning effect large energy efficiency effectiveness low operational inefficiency effect or discount rate however the corresponding supply chain efficiencies decrease and the manufacturer s profit proportions are less than 2 3 investigation of supply chain performance with competition from multiple retailers implies that the effects of system parameters on supply chain performance keep the same directions of single manufacturer retailer setup while competition improves supply chain efficiency and manufacturer s profit proportion this work contributes in involving cost learning and operational inefficiency effects simultaneously in a dynamic environment to explore supply chain performance

modeling renewable energy company risk abstract the renewable energy sector is one of the fastest growing components of the energy industry and along with this increased demand for renewable energy there has been an increase in investing and financing activities the tradeoff between risk and return in the renewable energy sector is however precarious renewable energy companies are often among the riskiest types of companies to invest in and for this reason it is necessary to have a good understanding of the risk factors this paper uses a variable beta model to investigate the determinants of renewable energy company risk the empirical results show that company sales growth has a negative impact on company risk while oil price increases have a positive impact on company risk when oil price returns are positive and moderate increases in sales growth can offset the impact of oil price returns and this leads to lower systematic risk

energy intake and productivity of guatemalan sugarcane cutters an empirical test of the efficiency wage hypothesis part ii abstract this paper examines additional evidence of an empirical test of the productivity consumption relation of the efficiency wage hypothesis a cross sectional analysis showed sharply diminishing productivity returns to higher levels of daily energy intake of guatemalan sugarcane cutters no positive and consistent energy supplementation effect on the daily supply of work units could be demonstrated in a time series analysis energy supplementation did not have a delayed impact on worker productivity it is concluded that increased energy availability may not necessarily result in increased productivity of rural workers who are moderately energy deficient

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

the impact of foresight in a transboundary pollution game abstract we study the impact of foresight in a transboundary pollution game i e the ability of a country to control its emissions taking into account the relationship between current emissions and future levels of pollution and thus on future damages we show that when all countries are myopic i e choose the laisser faire policy their payoffs are smaller than when all countries are farsighted i e non myopic however in the case where one myopic country becomes farsighted we show that the welfare impact of foresight on that country is ambiguous foresight may be welfare reducing for the country that acquires it this is due to the reaction of the other farsighted countries to that country s acquisition of foresight the country that acquires foresight reduces its emissions while the other farsighted countries extend their emissions the overall impact on total emissions is ambiguous moreover our results suggest that incentive mechanisms that involve a very small possibly zero present value of transfers can play an important role in inducing a country to adopt a farsighted behavior and diminishing the number of myopic countries these incentives would compensate the myopic country for the short run losses incurred from the acquisition of foresight and can be reimbursed by that country from the gains from foresight that it enjoys in the long run

correlations and volatility spillovers between oil prices and the stock prices of clean energy and technology companies abstract in this paper multivariate garch models are used to model conditional correlations and to analyze the volatility spillovers between oil prices and the stock prices of clean energy companies and technology companies four different multivariate garch models bekk diagonal constant conditional correlation and dynamic conditional correlation are compared and contrasted the dynamic conditional correlation model is found to fit the data the best and generates results showing that the stock prices of clean energy companies correlate more highly with technology stock prices than with oil prices on average a 1 long position in clean energy companies can be hedged for 20 cents with a short position in the crude oil futures market

dual role of price and myopia in a marketing channel abstract in this paper we study a dynamic two player channel where the manufacturer controls the wholesale price and the investment in quality and the retailer chooses the retail price we consider that the retail price affects both the demand and the perceived quality of the brand and that its variations contribute to the building of an internal reference price one of the model s distinctive features is that it accounts for the two meanings of price i e its classical objective measure of the cost of acquiring a particular quantity of the product and its subjective roles as an assessment of the quality of the product and an evaluation of gains or losses deal vs sacrifice resulting from buying a cheap or an expensive product this dual computation is done with respect to the internal reference price our objective is to investigate the impact of retailer s myopia on the pricing strategies and payoffs of channel members in this context a myopic retailer is an agent that disregards the effects of its pricing strategy on the evolution of the perceived brand quality and the reference price

multi period pricing in the presence of competition and social influence abstract this paper examines single and dynamic pricing policies of two competing firms over two periods in the presence of social influence assuming two firms adopt the same pricing policy we find that under either pricing policy firm profits always decrease with the degree of social influence firms prefer dynamic pricing policy when social influence is either relatively weak or sufficiently strong for firms under dynamic pricing policy to set zero prices in the first period otherwise single pricing policy is more preferable the conclusions are similar when the market size varies over periods except that dynamic pricing policy is always more profitable if the market size in period 2 is sufficiently large we have further compared the two pricing policies with posted pricing policy the results show that dynamic pricing policy dominates when social influence is relatively weak while posted pricing policy dominates when social influence is sufficiently strong because of the synergy between social influence and the reference price effect finally when each firm freely chooses either single or dynamic pricing policy we find that if the degree of social influence is relatively small two asymmetric equilibria exist where two firms adopt different pricing policies if the degree of social influence is very large however the unique equilibrium is both firms adopting dynamic pricing policy these findings provide important implications for firms to make more informed pricing decisions in an increasingly competitive environment with strong social influence

explicit solutions of optimization models and differential games with nonsmooth asymmetric reference price effects models in marketing with asymmetric reference effects lead to nonsmooth optimization problems and differential games which cannot be solved using standard methods in this study we introduce a new method for calculating explicitly optimal strategies open loop equilibria and closed loop equilibria of such nonsmooth problems application of this method to the case of asymmetric reference price effects with loss aversive consumers leads to the following conclusions 1 when the planning horizon is infinite after an introductory stage the optimal price stabilizes at a steady state price which is slightly below the optimal price in the absence of reference price effects 2 the optimal strategy is the same as in the symmetric case but with the loss parameter determined by the initial reference price 3 competition does not change the qualitative behavior of the optimal strategy 4 adopting an appropriate constant price strategy results in a minute decline in profits

efficient algorithms for the dynamic pricing problem with reference price effect we analyze a finite horizon dynamic pricing model in which demand at each period depends on not only the current price but also past prices through reference prices a unique feature but also a significant challenge in this model is the asymmetry in reference price effect which implies that the underlying optimization problem is nonsmooth and no standard optimization methods can be applied we identify a few key structural properties of the problem which enable us to develop strongly polynomial time algorithms to compute the optimal prices for several plausible scenarios we complement our exact algorithms by proposing an approximation heuristic and provide an upper bound on the optimal objective value finally we conduct numerical experiments to study the optimal price path and demonstrate the value of dynamic pricing when demands are seasonal we further compare numerically one of the exact algorithms with the heuristic and offer managerial suggestions this paper was accepted by yinyu ye optimization

relationship between green bonds and financial and environmental variables a novel time varying causality abstract in this paper we examine the time varying causal relationship between green bonds and other assets including us conventional bonds wilderhill clean energy equity index and co2 emission allowances price during the period spanning from 30 july 2014 to 10 february 2020 we apply the novel time varying granger causality test shi et al 2018 based on the recursive evolving algorithm introduced by phillips et al 2015a 2015b for controlling financial bubbles to detect real time causality detecting possible changes in the causal direction and dating financial turbulences the study based on this algorithm reveals a significant causality running from the us 10 year treasury bond index to green bonds starting from the end of the year 2016 until the end of the sample period besides we find that the link co2 emission allowances price causing green bonds is significant from the beginning of the sample period to the end of the year 2015 furthermore by using the recursive evolving causality algorithm of the shi et al 2018 test we find that the causality running from the clean energy index to green bonds is very limited to the year 2019 on the other hand there is no significant causality running from green bonds to all considered assets indicating no predictive power for this asset in its proper domain which is not yet examined in the literature

technical note dynamic pricing with gain seeking reference price effects we study a dynamic pricing problem of a firm facing reference price effects at an aggregate demand level where demand is more sensitive to gains than losses we find that even the myopic pricing strategy belongs to one type of discontinuous maps which can exhibit complex dynamics over time our numerical examples show that in general the optimal pricing strategies may not admit any simple characterizations and the resulting reference price price dynamics can be very complicated we then show for a special case that a cyclic skimming pricing strategy is optimal and we provide conditions to guarantee the optimality of high low pricing strategies

the impact of reference price effects on the profitability of price promotions this paper investigates the impact of reference price effects on retailer price promotions and describes why these effects can make promoting profitable first we analyze the profit impact of reference price effects generated by a single period of promotion the promotion can increase profit if the gain that these effects create in the promotion period outweighs the loss they create in future periods we then describe how retailers can estimate the optimal strategy of recurring promotions that maximizes profits from reference price effects over a time horizon examples of such strategies are presented for a retailer selling a national brand of peanut butter we obtain insights into how promotion prices timing and profits are affected by changes in costs interest rates consumers reactions to reference price effects and error in estimates used in the model the retailer s optimal reaction to a trade deal is also examined this strategy involves a phase of increased promotion activity sandwiched between phases of decreased activity we explain these results using the effects described in the single period model

reference effects of price and promotion on brand choice behavior when consumers are exposed to pricing and promotional activity by frequently purchased packaged goods they may develop expectations that are used as points of reference in evaluating future activi

systemic risk in european sovereign debt markets a covar copula approach abstract we studied systemic risk in european sovereign debt markets before and after the onset of the greek debt crisis taking the conditional value at risk covar as a systemic risk measure characterized and computed using copulas we found that before the debt crisis sovereign debt markets were all coupled and systemic risk was similar for all countries however with the onset of the greek crisis debt markets decoupled and the systemic risk of the countries in crisis excepting spain for the european debt market as a whole decreased whereas that of the non crisis countries increased to a small degree the systemic risk of the greek debt market for other countries in difficulties increased especially for portugal where systemic risk tripled after the onset of the crisis whereas the systemic impact on the non crisis countries decreased

an investigation of reference price segments abstract empirical research on reference price has typically assumed that consumers use either an internal reference price irp or an external reference price erp but not both in brand choice decisions in this article the authors assume that consumers use both irp and erp but may consider one of them more salient than the other the authors develop a model that segments consumers on the basis of the differences in the importance they assign to each type of reference price as well as in their brand preferences and responses to marketing mix variables the authors calibrate the model on data for four categories liquid detergents ketchup tissue and yogurt in all four categories the proposed model performs significantly better than the one that assumes that consumers use either irp or erp exclusively the authors discuss the managerial implications of this finding

production inventory and pricing under cost and demand learning effects abstract the paper considers a monopolist firm that plans its production inventory and pricing policy over a fixed and finite horizon the problem is represented by an optimal control model which combines elements from three streams of literature the first of these is a classical or area and deals with optimal production and inventory under exogenously given demand conditions the second is an area of marketing science which studies dynamic pricing under demand learning effects demand learning refers to the situation where current demand for a product is influenced by past demand the third area belongs to microeconomics and industrial organization and is concerned with the effects of learning by doing in a firm s production process learning is reflected in a unit production cost that decreases with cumulative production using a path synthezising procedure we obtain closed form characterizations of optimal production pricing and inventory policies

prisoner s dilemma on behavioral choices in the presence of sticky prices farsightedness vs myopia abstract when making decisions in a dynamic environment myopic supply chain members tend to ignore the future effects of their decisions on the evolution of state dynamics by contrast far sighted decision makers consider about the impacts of current decisions on both current profits and future profits in order to study how behavioral choices affect the operation decisions and profits of supply chain members we develop a differential game with sticky prices where one manufacturer purchases components from one supplier and makes final products for end customers the supplier decides on its wholesale price while the manufacturer sets its production quantity either of supply chain members has two behavioral choices myopia and farsightedness we derive and compare equilibrium solutions under four different behavioral combinations our analysis shows that there always exists a prisoner s dilemma caused by behavioral choices farsightedness is a dominant strategy for either the supplier or the manufacturer but both to act myopically makes both of them better off furthermore comparing with other scenarios the whole supply chain obtains the highest profit when both players are myopic in addition we introduce a revenue sharing contract with static wholesale price to mitigate the adverse impacts of the prisoner s dilemma

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

downside and upside risk spillovers between exchange rates and stock prices abstract we examined downside and upside risk spillovers from exchange rates to stock prices and vice versa for a set of emerging economies we characterized the dependence structure between currency and stock returns using copulas and computed downside and upside value at risk and conditional value at risk we documented a positive relationship between stock prices and currency values in emerging economies with respect to the us dollar and the euro with downside and upside spillover risk effects transmitted both ways finally we also documented asymmetries in upside and downside risk spillovers and asymmetric differences in the size of risk spillovers when the domestic currency values against the us dollar and the euro our results consistent with flight to quality phenomena have implications for downside and upside risk management of international investor portfolios in emerging markets

drivers of green bond market growth the importance of nationally determined contributions to the paris agreement and implications for sustainability abstract green bonds are increasingly being applied to finance emissions reductions sustainable development and other cleaner production investments conducive to reaching the 2 c temperature target of the paris agreement as their markets are relatively nascent there is a gap in the empirical literature on the drivers of green bond market growth to assess the impact that capital market growth drivers and nationally determined contributions to the paris agreement have on green bond issuance volumes as indicators of market growth this study employed a structural equation model using a panel dataset of over 300 billion in green bonds issued in 49 countries between 2007 and 2017 this is the first econometric study to demonstrate unique drivers of green bond market growth in addition to factors that similarly affect conventional bond market growth this is also the first study to construct a normalized index of nationally determined contributions robustness scores to measure their impacts on green bond market growth macroeconomic latent factors exerted three times the total influence exerted by institutional latent factors institutional effects are positive and indirect while oecd membership impacts were small and statistically insignificant nationally determined contributions scores exerted the largest positive and statistically significant impacts among observed variables these results suggest that nationally determined contributions and other macroeconomic and institutional factors are driving growing green bond issuances that will finance climate and sustainability investments through the future they also highlight the need for broader examinations of the determinants of green bond issuances as investment vehicles for sustainable outcomes

note the role of returns policies in pricing and inventory decisions for catalogue goods manufacturers often use returns policies to encourage retailers to stock and price items more aggressively we focus on the effect that such policies have on both a retailer s and a manufacturer s profits when the retailer must commit prior to the selling season to both a stocking quantity and a price at which to sell an item such a commitment is often necessary for retailers who sell primarily through catalogues

stock prices of clean energy firms oil and carbon markets a vector autoregressive analysis recent discussions of energy security and climate change have attracted significant attention to clean energy we hypothesize that rising prices of conventional energy and or placement of a price on carbon emissions would encourage investments in clean energy firms the data from three clean energy indices show that oil prices and technology stock prices separately affect the stock prices of clean energy firms however the data fail to demonstrate a significant relationship between carbon prices and the stock prices of the firms

pricing and manufacturing decisions when demand is a function of prices in multiple periods in most deterministic manufacturing decision models demand is either known or induced by pricing decisions in the period that the demand is experienced however in more realistic market scenarios consumers make purchase decisions with respect to price not only in the current period but also in past and future periods we model a joint manufacturing pricing decision problem accounting for that portion of demand realized in each period that is induced by the interaction of pricing decisions in the current period and in previous periods we formulate a mathematical programming model and develop solution techniques we identify structural properties of our models and develop closed form solutions and effective heuristics for various special cases of our models finally we conduct extensive computational experiments to quantify the effectiveness of our heuristics and to develop managerial insights

is there dependence and systemic risk between oil and renewable energy stock prices abstract we study systemic risk and dependence between oil and renewable energy markets using copulas to characterize the dependence structure and to compute the conditional value at risk as a measure of systemic risk we found significant time varying average and symmetric tail dependence between oil returns and several global and sectoral renewable energy indices our evidence on systemic risk indicates that oil price dynamics significantly contributes around 30 to downside and upside risk of renewable energy companies these results have important implications for risk management and renewable energy policies

asymmetric reference price effects and dynamic pricing policies we consider a group of frequently purchased consumer brands which are partial substitutes and examine two situations the first where the group of brands is managed by a retailer and second where the brands compete in an oligopoly we assume that demand is a function of actual prices and reference prices and develop optimal dynamic pricing policies for each situation in addition to researchers studying pricing strategy our results may interest retailers choosing between hi lo pricing and an everyday low price and manufacturers assessing whether to follow procter gamble s lead and replace a policy of funding consumer price reductions through trade deals with a constant wholesale price a reference price is an anchoring level formed by customers based on the pricing environment the literature suggests that demand for a brand depends not only on the brand price but also whether the brand price is greater than the reference price a perceived loss or is less than it a perceived gain the responses to gains and losses are asymmetric broadly speaking we find that when enough consumers weigh gains more than losses the optimal pricing policy is cyclical likewise when they weigh losses more than gains a constant price is optimal thus we provide a rationale for dynamic pricing which is quite distinct from the three explanations previously offered 1 decreasing unit variable costs due to learning effects 2 the transfer of inventory to consumers who face lower inventory holding costs than do retailers and 3 competitive effects our explanations apply even when the other explanations do not i e in mature product categories where learning effects are minimal when retailer inventories are minimized through the use of just in time policies and when competitive effects do not exist as in a monopoly greenleaf 1995 has shown numerically that in the presence of reference price effects the optimal pricing policy for a monopolist can be cyclical we first analytically extend greenleaf s result to a monopolist with a constant cost of goods facing a homogeneous market where all customers either weigh gains more than losses or vice versa using this building block we examine a monopolist retailer managing multiple brands we assume that demand is a linear function of prices of multiple brands and together with an expression which reflects the reference price effect further we assume that the retailer maximizes average profit per period next we analyze a duopoly and extend the results to an oligopoly we assume that the manufacturers are able to set the retail prices as in an integrated channel here we retain the same demand function as for the retailer and derive markov perfect nash equilibria we use two alternative processes of reference price formation the exponential smoothed es past price process which is frequently used in the literature and for the multi brand situations the recently proposed reference brand rb process hardie johnson and fader 1993 in the latter the reference price is the current price of the last brand bought the reference brand we adapt the individual level rb formulation in hardie et al to an aggregate demand specification for the es process we obtain most results analytically for the rb process we use simulation finally we extend our results to a population with two customer segments segment 1 which weighs gains more than losses and segment 2 which does the opposite i e is loss averse when the market consists exclusively of segment 1 customers and es is the reference price process we find that prices are cyclical in all cases analyzed i e for a monopoly a monopolist retailer managing multiple brands a duopoly and an oligopoly if the rb formulation is the underlying process a monopolist retailer managing two brands uses cyclical prices but in a duopoly the equilibrium solution is for the brands to maintain constant prices when all customers belong to segment 2 i e they are loss averse constant prices are optimal in all cases for both reference price formulations when the population consists of both segment 1 and segment 2 and the es process applies we develop a sufficient condition for cyclical pricing policies to be optimal the condition is expressed in terms of the proportion of the two segment sizes the absolute difference between the gain and loss parameters of each segment and their respective exponential smoothing constants interestingly for reasonable values of the latter two factors cyclical policies are optimal even when the proportion of segment 1 is quite small similar magnitudes are obtained numerically for the rb case

manufacturer retailer contracting with asymmetric information on retailer s degree of loss aversion abstract in a recent paper wang c webster s 2007 channel coordination for a supply chain with a risk neutral manufacturer and a loss averse retailer decision sciences 38 3 361 389 the authors study a supply chain consisting of a risk neutral manufacturer and a loss averse retailer and show that the supply chain can be coordinated by three contracts buy back bb gain loss sharing gl and gain loss sharing and buy back glb they assume that the retailer s degree of loss aversion is common knowledge however this assumption cannot reflect real situations since in the real industry one party s degree of loss aversion is usually unknown by other parties in the present paper we propose a principal agent model assuming the retailer s degree of loss aversion to be asymmetric information within the principal agent framework we obtain the following results 1 an optimal mgl modified gl contract menu which is based on the gl contract studied in wang and webster 2007 is derived for the manufacturer the principal by mechanism design theory 2 under the mgl contract menu information asymmetry lowers the production quantity decreases the manufacturer s profit and deteriorates supply chain performance while increasing the retailer s utility 3 the mgl contract menu can coordinate the supply chain with asymmetric information in an implementable way if the wholesale price is endogenously determined by the manufacturer and its lower bound is 0

dynamic pricing with loss averse consumers and peak end anchoring we study the dynamic pricing implications of a new behaviorally motivated reference price mechanism based on the peak end memory mode this model suggests that consumers anchor on a reference price that is a weighted average of the lowest and most recent prices loss averse consumers are more sensitive to perceived losses than gains relative to this reference price we find that a range of constant pricing policies is optimal for the corresponding dynamic pricing problem this range is wider the more consumers anchor on lowest prices and it persists when buyers are loss neutral in contrast with previous literature in a transient regime the optimal pricing policy is monotone and converges to a steady state price which is lower the more extreme and salient the low price anchor is our results suggest that behavioral regularities such as peak end anchoring and loss aversion limit the benefits of varying prices and caution that the adverse effects of deep discounts on the firm s optimal prices and profits might be more enduring than previous models predict

could myopic pricing be a strategic choice in marketing channels a game theoretic analysis abstract we identify the conditions under which a myopic pricing behavior could be a profit enhancing tool in the distribution channel a channel member is myopic when he ignores the evolution of the retail prices when actual and past retail prices affect consumers purchasing decisions a differential game is formulated where channel members control transfer and retail prices we start by examining a bilateral monopoly and then introduce competition at the manufacturing level the competing manufacturers play a la nash and can be both myopic both farsighted or one myopic while the other is farsighted we show that for a bilateral monopoly myopia enhances total channel profit when the effect of the reference price is small enough this remains true under competition at the manufacturing level when products are differentiated enough

promotion effect on endogenous consumption over the years researchers have found that promotion makes consumers switch brands and purchase earlier or more however it is unclear how promotion affects consumption especially for product categories that are perceived to be versatile and substitutable in this paper we propose a dynamic structural model with endogenous consumption under promotion uncertainty to analyze the promotion effect on consumption this model recognizes consumers as rational decision makers who form promotion expectations and plan their purchase and consumption decisions in light of promotion schedule applying the proposed model to packaged tuna and yogurt we find that endogenous consumption responds to promotion as a result of forward looking and stockpiling behavior this is the first empirical paper that recognizes consumption as an endogenous decision variable and proposes a structural model to offer behavioral explanations on whether how and why promotion encourages consumption for product categories with flexible consumption

dynamic pricing and warranty policies for products with fixed lifetime abstract we consider a repairable product with known market entry and departure times a warranty policy is offered with product purchase under which a customer can have a failed item repaired free of charge in the warranty period it is assumed that customers are heterogeneous in their risk attitudes toward uncertain repair costs incurred after the warranty expires the objective is to determine a joint dynamic pricing and warranty policy for the lifetime of the product which maximizes the manufacturer s expected profit in the first part of the analysis we consider a linearly decreasing price function and a constant warranty length we first study customers purchase patterns under several different pricing strategies by the manufacturer and then discuss the optimal pricing and warranty strategy in the second part we assume that the warranty length can be altered once during the product lifetime in developing a joint pricing and warranty policy numerical studies show that a dynamic warranty policy can significantly outperform a fixed length warranty policy

monopolist pricing with dynamic demand and production cost this paper deals with pricing of a new product over time by a monopolist who maximizes the discounted profit stream the interdependency of cost and demand on cumulative production makes the problem inherently dynamic cost is assumed to be declining with cumulative production learning curve effect while demand is a function of price and cumulative sales representing word of mouth and saturation effects the paper addresses this problem in a general framework that includes several previous results as special cases and provides new insights in other situations while the learning curve and word of mouth effect cause prices to be lower than the price that maximizes immediate revenues the saturation factor has the opposite effect the price path over time is affected by these factors and the interest rate we characterize the price path under several different situations and interpret the results for policy guidelines
