product cannibalization and the role of prices the role of brand prices in contributing to product cannibalization is examined price elasticities and reference price theory are used to provide a theoretical foundation and empirical test for the impact of a firm s cheap brand on one of its expensive brands results are consistent with the conclusion that the market share of the company s premium brand was cannibalized by a growth in sales of its cheap brand

agricultural price instability a survey of competing explanations and remedies there are two explanations for agricultural price dynamics one follows cobweb logic and models fluctuations driven by expectation errors but emphasises that these expectations create complex dynamics and possibly chaos the other stems from the rational expectations tradition of dynamics driven by real shocks the empirical evidence tends to support the latter but is not conclusive the rational expectations model generates an optimal dynamic path from which no improvement can be expected from public intervention however if we take account of all the potential market failures in agricultural markets and especially in developing countries this conclusion might require some qualifications although an appropriate policy design for stability has still to be achieved this paper surveys the positive and normative literature on agricultural prices highlighting empirical evidence and identifying remaining unresolved issues

complex dynamics in a cobweb model with adaptive production adjustment abstract chaos occurs in a nonlinear cobweb model with normal demand and supply naive expectations and adaptive production adjustment the model differs from existing ones in that it includes adaptive production adjustment instead of adaptive expectations the model exhibits observable chaos strange attractors as well as topological chaos horseshoes associated with homoclinic points as numerical simulations show the faster suppliers adjust their production and the more inelastic demand is the more likely the market behaves chaotically

constrained pareto optimal taxation of labour and capital incomes abstract with the pareto principle as the sole normative criterion necessary conditions for optimal tax rates on labour and capital incomes are established in an overlapping generations model the individuals in the economy have differing earning abilities and their labour supply is endogenous the analysis focuses on intragenerational aspects and is restricted to linear taxation in steady state

loss aversion in post sale purchases of consumer products and their substitutes this paper considers the measurement of consumer loss aversion in product markets we introduce a test based on a substitution effect focusing on how the end of a sale affects sales not of the good itself but a substitute good such an effect cannot be easily confounded with consumer stockpiling using a unique dataset from an online hardware retailer we find evidence consistent with consumer loss aversion moreover we find that less experienced consumers suffer a more prominent loss aversion bias compared to more experienced consumers

the boundaries of loss aversion abstract in this article the authors propose some psychological principles to describe the boundaries of loss aversion a key idea is that exchange goods that are given up as intended do not exhibit loss aversion for example the authors propose that money given up in purchases is not generally subject to loss aversion the results of several experiments provide preliminary support for the hypotheses the authors find that consistent with prospect theory loss aversion provides a complete account of risk aversion for risks with equal probability to win or lose the authors propose boundaries for this result and suggest further tests of the model

dynamics of the cobweb model with adaptive expectations and nonlinear supply and demand the price quantity dynamics of the cobweb model with adaptive expectations and nonlinear supply and demand curves is analysed we prove that chaotic dynamical behaviour can occur even if both the supply and demand curves are monotonic the introduction of adaptive expectations into the cobweb model leads to price quantity fluctuations with a smaller amplitude however at the same time the price quantity cycles may become unstable and chaotic oscillations may arise we present a geometric explanation why chaos can occur for a large class of nonlinear monotonic supply and demand curves

deficits and intergenerational welfare in open economies this paper deals with public debt in open economies extending diamond s overlapping generations model to a small open economy as well as an international equilibrium of two large economies it focuses on the intergenerational welfare redistributions caused by an increase in public debt triggered by a temporary government budget deficit and shows how these redistributions differ in open and closed economies the interplay between the deficits in the government budget and the current account is also analyzed it is shown how a single period with a government deficit can be followed by a sequence of periods with a deficit in the current account

capital accumulation and the characteristics of private intergenerational transfers many recent studies of the process of family accumulation in general and household response to social security in particular have revealed growing dissatisfaction with the life cycle theory of saving see for example barro 1978 kotlikoff 1979 darby 1979 kotlikoff and summers 1981 kurz 1981 blinder gordon and wise 1981 david and menchik 1982 leimer and lesnoy 1982 an alternative to the life cycle hypothesis is expressed by defining the preference of each family over its own consumption as well as the welfare of the generations that follow thus each family consists of an infinite chain of generations who have interdependent preferences and for this reason we shall call it the inter generational hypothesis it was recently used by barro 1974 1978 to attack the conclusions of the life cycle hypothesis our purpose in this paper is to start the long road of studying the structure of the private inter generational transfer system with the aim of providing additional tests of the two competing hypotheses

dynamic tax incidence and intergenerationally neutral reform the paper proposes a basic definition of intergenerational neutrality in the overlapping generations model when agents have a pure life cycle motive of savings the derivation of intergenerationally neutral tax effects provides a redistribution free benchmark case that isolates the relative price effects of taxes and the deadweight losses associated with them the paper clarifies the intergenerational incidence which has to be determined simultaneously with the substitution effects of taxes on savings a tax reform example demonstrates how taxes with diverging intergenerational incidence may be combined to achieve intergenerational neutrality finally the paper extends the analysis of generational tax incidence to the case of a small open economy

mental accounting and changes in price the frame dependence of reference dependence mental accounting principles for multiple events were replicated and then extended to pricing situations that were designed to moderate these principles if reference dependence is proportional i e if consumers evaluate events in terms of proportional deviations from reference states rather than raw deviations prices were stated with or without popular percentage based pricing frames such as 33 off mental accounting principles generally prevailed in the absence of percentage based frames however percentage based frames altered two principles and increased tendencies toward the others the findings demonstrate that mental accounting principles price perception and reference dependence are sensitive to the ways in which deviations from reference states are framed

non reservation price equilibria and consumer search abstract reservation price equilibria rpe do not accurately assess market power in consumer search markets in most search markets consumers do not know important elements of the environment in which they search such as for example firms cost we argue that when consumers learn when searching rpe suffer from theoretical issues such as non existence and critical dependence on specific out of equilibrium beliefs we characterize equilibria where consumers rationally choose search strategies that are not characterized by a reservation price non rpe always exist and do not depend on specific out of equilibrium beliefs non rpe have active consumer search and are consistent with recent empirical findings

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

tax effects versus budget effects on labor supply this paper analyzes the effects on labor supply of parallel changes in taxes and public spending of various types a number of important recent developments in the labor supply behavior of households are highlighted by such a study of various types of budget effects rather than isolated tax effects this comes out in particular when considering cross substitution effects on labor supply of changes in public spending on goods and services or of the subsidization of goods and services provided by private markets moreover the income effects of tax changes are often mitigated or possibly even removed by the income effects of the accompanying expenditure changes

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

looking for loss aversion in scanner panel data the confounding effect of price response heterogeneity recent work in marketing has drawn on behavioral decision theory to advance the notion that consumers evaluate attributes and therefore choice alternatives not only in absolute terms but asdeviations from a reference point the theory has important substantive and practical implications for the timing and execution of price promotions and other marketing activities choice modelers using scanner panel data have tested for the presence of these reference effects in consumer response to an attribute such as price in applications of the theory of reference dependent choice tversky and kahneman 1991 some modelers report empirical evidence of loss aversion when a consumer encounters a price above his or her established reference point a loss the response is greater than for a price below the reference point a gain researchers have gone so far as to suggest that evidence for the so called reference effect make it an empirical generalization in marketing e g kalyanaram and winer 1995 meyer and johnson 1995 it is our contention that the measurement of loss aversion in empirical applications of the reference dependent choice model is confounded by the presence of unaccounted for heterogeneity in consumer price responsiveness our reasoning is that the kinked price response curve implied by loss aversion is confounded with the slopes of the response curves across segments that are differentially responsive to price a more price responsive consumer with a steeper response function tends to have a lower price level as a reference point this consumer faces a larger proportion of prices above his reference point thus the response curve is steeperin the domain of losses similarly the less price responsive consumer sees a greater proportion of prices below his reference point so the response curve is less steep within the domain of gains as a result any cross sectional estimate of loss aversion that does not take this into account will be biased upward researchers who do not control for heterogeneity in price responsiveness may arrive at incorrect substantive conclusions about the phenomenon it is interesting to note that in this instance failure to control for heterogeneity induces a bias infavor of finding an effect rather than the more typical case of attenuation of the effect toward zero we first test our assertion regarding the referencedependent model using scanner panel data on refrigerated orange juice and subsequently extend this analysis to 11 additional product categories in all cases we find as predicted that accounting for price response heterogeneity leads to lower and frequently nonsignificant estimates of loss aversion we do however find some categories in which the effect does not disappear altogether we also estimate loss aversion using a sticker shock model of brand choice in which the reference prices arebrand specific in line with the results of the majority of prior literature we find smaller and insignificant estimates of loss aversion in this model we show that this is because in the sticker shock model there is no apparent correlation between the price responsiveness of the consumer and the representation of reference effects as losses or gains our findings strongly suggest that loss aversion may not in fact be a universal phenomenon at least in the context of frequently purchased grocery products

an upper bound on optimal income taxes abstract the message of this paper is very simple a certain range of tax rates determined by supply and demand functions only can be disregarded in linear optimal taxation approaches before any interpersonal utility comparisons are made in particular no marginal tax rate above a certain level can be optimal with respect to pareto inclusive social orderings it is shown that is in general not larger than and sometimes strictly less than the minimal tax rate at which tax revenues are maximal conditions under which is the least upper bound are given and a comparison is made with tax rates obtained by the rawlsian maximin principle

welfare effects of alternative forms of public spending the paper analyzes welfare effects in a second best world of public spending of three different types transfer payments public consumption and public investment it is shown how these effects d

intergenerational aspects of public transfers borrowing and debt the paper analyzes intergeneration distributional effects of taxes transfer payments public borrowing and debt a two period life cucle model with overlapping generations is constructed the model has two specific features private wealth in both periods enter as arguments in the preference function and the individuals inelastically supply labor in both periods it turns out that some fiscal policy actions favor both of the currently lliving generations possibly at the expense of future generations while other actions generate conflicts between the currently living generations the analysis also shows that it makes considerable difference whether the burden of public spending debt and borrowing is defined in terms of wealth consumption and utility the different implications of foreign vs domestic debt are examined

output effects of government purchases the theoretical analysis focuses on the distinction between temporary and permanent movements in government purchases under plausible conditions the temporary case involves an output response that is positive less than one to one with the change in government purchases and larger than that generated by an equal sized but permanent shift in purchase the equilibrium real rate of return rise in the temporary case but changes little in the permanent one defense purchases are divided empirically into permanent and temporary components by considering the role of temporary wars no temporary shifts in nondefense purchases were isolated empirical results verify an expansionary output effect for temporary purchases that exceeds that of permanent purchases the results for some other expectational hypotheses are found to be generally supportive of the theory

modeling loss aversion and reference dependence effects on brand choice based upon a recently developed multiattribute generalization of prospect theory s value function tversky and kahneman 1991 we argue that consumer choice is influenced by the position of brands relative to multiattribute reference points and that consumers weigh losses from a reference point more than equivalent sized gains loss aversion we sketch implications of this model for understanding brand choice we develop a multinomial logit formulation of a reference dependent choice model calibrating it using scanner data in addition to providing better fit in both estimation and forecast periods than a standard multinomial logit model the model s coefficients demonstrate significant loss aversion as hypothesized we also discuss the implications of a reference dependent view of consumer choice for modeling brand choice demonstrate that loss aversion can account for asymmetric responses to changes in product characteristics and examine other implications for competitive strategy

caution implies profit abstract the paper illustrates by simple cobweb models that under certain circumstances fluctuations in perpetual disequilibrium may not only be viable but also preferable to a competitive equilibrium from the long run perspective

when do price thresholds matter in retail categories marketing literature has long recognized that brand price elasticity need not be monotonic and symmetric but has yet to provide generalizable market level insights on threshold based price elasticity asymmetric thresholds and the sign and magnitude of elasticity transitions this paper introduces smooth transition regression models to study threshold based price elasticity of the top 4 brands across 20 fast moving consumer good categories threshold based price elasticity is found for 76 of all brands 29 reflect historical benchmark prices 16 reflect competitive benchmark prices and 31 reflect both types of benchmarks the authors demonstrate asymmetry for gains versus losses on three levels the threshold size and the sign and the magnitude of the elasticity difference interestingly they observe latitude of acceptance for gains compared to the historical benchmark but saturation effects in most other cases moreover category characteristics influence the extent and the nature of threshold based price elasticity while individual brand characteristics impact the size of the price thresholds from a managerial perspective the paper illustrates the sales revenue and margin implications for price changes typically observed in consumer markets

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

economists and the welfare state abstract this paper constrasts the views of the welfare state of economists in the 1940s and 1950s with those of the current generation it is argued that economists as a profession in particular in the scandinavian countries have changed from being strong spokesmen for the welfare state to becoming much more critical the reasons for this are sought both in the expansion of the public sector in recent decades and in the development of economic theory in the areas of public finance insurance and incentives and public choice an attempt is made to evaluate the importance of the empirical and theoretical developments for the changing views of the welfare state

remaining puzzles and neglected issues in macroeconomics this paper analyses the chain of transmission mechanisms of economic policy actions to financial markets output and employment and finally unemployment in an attempt to identify remaining puzzles and neglected issues in macroeconomics the paper emphasizes the consequences of fiscal and monetary policy actions on real variables including real interest rates and real exchange rates an attempt is made to explain why product demand shocks often tend to have faster effects on output and employment than on prices the paper also discusses why demand induced increases in output and employment are not systematically connected with a reduction in the product wage rate the paper ends with a discussion of various supply side considerations in macroeconomics

the effect of taxation on human capital this study finds a significant negative effect of proportional income taxation on human capital of the few earlier studies to address this issue most suggested a negligible effect of taxation on investment in human capital this earlier conclusion is shown to be incorrect by using a model that is more general in several respects than the models used previously

on reforming the welfare system abstract using a simulation model for a small open economy quebec 1986 various negative income tax nit and workfare schemes are compared from the point of view of efficiency and equity the main finding is that there exist workfare schemes that are superior both to the quebec regime of 1986 and to a nit characterized by a 100 percent implicit tax rate however these workfare schemes are dominated by some nit programs this suggests that it may be necessary to have work requirements that vary across socio demographic classes for a workfare plan to be superior to any nit combining workfare with an nit could also be the prescription

labour supply tax evasion and the marginal cost of public funds an empirical investigation abstract in this paper we extend the concept of marginal cost of public funds itmcf to incorporate tax evasion in the labour market mcf values are also computed from various tax reforms applied to the province of quebec canada 1985 for this purpose a utility based labour supply model that allows for both regular and irregular work activities is used at the benchmark situation the mcf associated with an increase in marginal income tax rates ranges between 1 39 and 1 53 depending upon whether we consider rationing or not moreover the presence of the irregular sector accounts for between 0 02 and 0 05 of this mcf although small in magnitude the impact of the irregular sector increases rapidly with the level of marginal tax rates

the effect of local consideration sets on global choice between lower price and higher quality a set of alternatives under consideration is often divided into subsets or local sets by some external e g product display format at the store or internal e g a decision rule factor we propose that the manner in which a global set of alternatives varying in price and quality is divided into local sets can have a systematic effect on consumer choice between a lower price alternative and a higher quality alternative three such effects are investigated 1 consumers who first choose from pairs of products a b b c a c and then choose from the set of all three products a b c are more likely to prefer the cheapest alternative than consumers who only choose from the complete set 2 the choice share of a low price low quality brand is greater when alternatives varying in price quality and features are displayed by brand i e each display presents different models of one brand as compared to a display by feature level i e each display presents comparable models of different brands and 3 consumers considering a pair of two option local sets each consisting of different brands and feature levels e g a feature enhanced model of a low quality brand vs a basic model of a high quality brand are more likely to select a feature enhanced model from the global set of four options than those who consider the same alternatives in other local set configurations or consider only the global set these predictions were supported in seven studies which also provided insights into the boundaries of the effects focusing on the paired comparison effect we discuss the theoretical and practical implications of the findings

research note estimating heterogeneous price thresholds a brand choice model with heterogeneous price threshold parameters is used to investigate a three regime piecewise linear stochastic utility function the model is used to explore the relationships between aspects of consumer price sensitivity and price thresholds using hierarchical bayes modeling with the markov chain monte carlo mcmc method this study contributes to the modeling literature on discontinuous likelihoods in choice models the empirical application using our scanner panel data set shows that the reference effect and loss aversion are more marked after price thresholds are taken into heterogeneous price response models furthermore loss aversion is attenuated by using price thresholds than by an aggregate homogeneity model without price thresholds

progressive income taxes test of efficiency upper bounds on efficient tax rates in a progressive labor income tax schedule are derived within the standard framework of optimal taxation a tax rate is efficient if it is not pareto dominated by any other tax rate the formulas derived are applied to the swedish 1982 tax schedule inefficiency is revealed for the middle income groups copyright 1990 by the editors of the scandinavian journal of economics

estimation of a composite food demand system for the united states this study develops statistical procedures for computing the parameters of a complete demand system a constrained maximum likelihood method has been applied and parametric restrictions derived from classical demand theory are introduced by a substitution approach the procedures are then applied to u s data for estimating a composite food demand system covering 12 food categories and one nonfood sector

empirical generalizations from reference price research considerable theoretical justification for consumers use of psychological reference points exists from the research literature from a managerial perspective one of the most important applications of this concept is reference price an internal standard against which observed prices are compared in this paper we propose three empirical generalizations that are well supported in the marketing literature first there is ample evidence that consumers use reference prices in making brand choices second the empirical results on reference pricing also support the generalization that consumers rely on past prices as part of the reference price formation process third consistent with other research on loss aversion consumers have been found to be more sensitive to losses i e observed prices higher than reference prices than gains we also propose topics for further research on reference prices

contract preferences and performance for the loss averse supplier buyback vs revenue sharing prior theory claims that buyback and revenue sharing contracts achieve equivalent channel coordinating solutions when applied in a dyadic supplier retailer setting this suggests that a supplier should be indifferent between the two contracts however the sequence and magnitude of costs and revenues i e losses and gains vary significantly between the contracts suggesting the supplier s preference of contract type and associated contract parameter values may vary with the level of loss aversion we investigate this phenomenon through two studies the first is a preliminary study investigating whether human suppliers are indeed indifferent between these two contracts using a controlled laboratory experiment with human subjects taking on the role of the supplier having to choose between contracts we find that contract preferences change with the ratio of overage and underage costs for the channel i e the newsvendor critical ratio in particular a buyback contract is preferred for products wit

tests of market outcomes with asymmetric valuations of gains and losses smaller gains fewer trades and less value abstract the pervasive finding that individuals value losses more than gains suggests that actual gains from trade and numbers of market exchanges may well be much smaller than would be the case if people s buying and selling prices were equivalent as normally assumed the results of two sets of costless market simulations using actual gain and loss valuations show that the actual gains from exchange and trade volumes are less than half of those expected with conventional assumptions and that completion of all pareto efficient exchanges fail by wide margins to shift entitlements to those willing to pay the most for them these findings suggest the valuation disparity has significant welfare implications and may be a major cause of market stickiness

uncertainty and optimal social security systems this paper examines the annuity aspect of social security within the framework of an overlapping generations model the duration of life is assumed to be uncertain under a fully funded system demand for social security is determined by each generation so as to maximize expected lifetime utility taking into account the welfare of future generations under a pay as you go system with intergenerational transfers demand for retirement benefits by the working population takes into account taxes paid by descendants it is shown that the two modes of finance are equivalent in terms of all real aggregates effects of changes in expected lifetime and in the birth rate are analyzed starting at the optimal level a compulsory balanced increase in social security taxes and benefits is shown to increase short run savings

the bright side of loss aversion in dynamic and competitive markets a well established phenomenon of consumer buying behavior is that consumers evaluate prices relative to a reference point and exhibit loss aversion i e their propensity to buy is more negatively affected by prices above the reference point than it is positively affected by prices below the reference point the objective of this paper is to analytically examine how the competitive strategy and profitability of firms are affected by the presence of consumer loss aversion in the price dimension although we assume that consumer loss aversion increases consumer propensity to search for lower prices we find that it does not necessarily lead to lower prices or profits when firms compete over multiple periods and when the consumer reference price in subsequent periods is affected by current prices specifically consumer loss aversion could lead to higher prices and profits when consumer valuation is sufficiently high relative to search costs and the proportion of consumers with positive search costs is in an intermediate range we also show that when forward looking firms incorporate the negative effect of price promotions on future profits the equilibrium range of price promotions may actually increase

price transmission and local market power empirical evidence from the austrian gasoline market we analyse the impact of local market power on price margins and different dimensions of price adjustment dynamics speed and asymmetry of price transmission using data for a large number of indiv

growth welfare and the size of government i introduction given the current state of political debate within the u s it would appear that making the claim a smaller government is a better government is just a mere statement of a simple fact president clinton the head of the political party which has traditionally supported a larger government has now proclaimed that the era of big government is over and has proposed fiscal programs to cut both taxes and the growth of government spending in a very real sense it has been economists who have been consensus makers on this issue numerous studies have been conducted recently estimating the growth and welfare costs of distortionary taxation 1 these studies have generally found that income and capital taxation have large welfare effects and also significant effects on growth however the potential benefits of the government purchases financed with distortionary taxes are very limited in these supply side models most often being simply ignored in these aforementioned studies government purchases do not directly provide utility to households and do not affect the productivity of firms as a result the optimal size of government in these models is zero which is a troubling property of any model being used to evaluate the effects of changes in fiscal policy in terms of cost benefit analysis by ignoring these effects previous studies have only considered the costs of a larger government but not the benefits 2 this paper develops an endogenous growth model of the u s economy in which government purchases directly affect both the utility of individuals through the provision of public consumption goods and services and the productivity of firms through the provision of public capital in a manner which is consistent with existing empirical work by aschauer 1985 1989 and munnell 1990a b among others by incorporating the full benefits of government purchases into our model the growth and welfare effects of a smaller government can be more realistically evaluated this paper proceeds as follows in section ii the endogenous growth model with human capital accumulation used in this study is described the competitive equilibrium of the model is described and calculated in section iii and the calibration of the parameters in the model is discussed in section iv in section v various fiscal policy experiments are conducted investigating the growth and welfare effects of government downsizing although this is a macroeconomic model and as such is too general to investigate the effects of specific government spending and taxation programs the results presented here do provide some broad fiscal policy guidelines 1 the effects of a smaller government depend as much on the mix of spending cuts as on the mix of tax cuts and government downsizing is not necessarily growth and welfare enhancing 2 while tax reductions by themselves can significantly increase growth and welfare simultaneous reductions in government spending and taxation are not likely to lead to large positive or negative changes in growth or welfare regardless of the exact form of the spending and tax cuts 3 reducing the size of government is less likely to increase growth and welfare if the reductions in public investment are large especially reductions in public investment which directly affect the accumulation of human capital 4 government downsizing is most likely to increase growth and welfare if the proceeds from spending cuts are used to finance reductions in capital tax rates 5 across the board spending cuts fail to maximize the potential growth and welfare benefits of government downsizing although downsizing is more likely to increase growth and welfare if the cuts pertain to all forms of government spending including transfer payments and not just government purchases ii description of the model the model developed here is similar to the well known two sector endogenous growth model used by rebelo 1991 and king and rebelo 1990 with endogenous labor supply

an empirical analysis of latitude of price acceptance in consumer package goods scanner panel data analyses for sweetened and unsweetened drink categories with four brands in each support the presence of a region of price insensitivity around a reference price the analyses also suggest that consumers with higher average reference price have a wider latitude of price acceptance consumers with a higher frequency of purchase i e shorter average interpurchase time interval are found to have a narrower latitude of price acceptance because they are more aware of the range of price distributions finally consumers with a higher average brand loyalty have a wider latitude of price acceptance demonstrating greater tolerance of price fluctuations

adaptive expectations and cobweb phenomena does heterogeneity matter this paper studies a cobweb type commodity market characterized by a strictly monotone demand and supply in which n types of firms operate types differ in a key parameter governing price expectations which are supposed to be adaptive the unique steady state of the resulting economic dynamics is characterized in terms of stability and the impact of the number of firms types is studied to this end the notions of structural and behavioural degree of instability which are introduced in the paper prove to be crucial in determining whether stability or instability prevail the case of market integration is also considered and conditions to have stability or instability in terms of the original markets parameters are given the baseline structure is extended in two directions the first extension assumes the point of view of an authority who is uncertain about the firms types in this case the structural degree of instability determines how heterogeneity affects the probability of ending up with a stable outcome the second extension consists in endogenizing the choice of predictors through a discrete choice based evolutionary mechanism in both cases the amount of the heterogeneity and its possible variations play a critical role in shaping the range of possible long run outcomes of the model

the cobweb borrowing and financial crises abstract studies of non linear cobweb models have failed to address a fundamental issue whether the complex dynamical behavior displayed by such models is consistent with the survival of producers this paper shows that where borrowing is unconstrained as is implicitly assumed in standard cobweb models borrowing results in financial crises incorporating constraints on borrowing is needed to salvage cobweb models industry performance in terms both of profitability and of the incidence of bankruptcies is highly sensitive to the nature of such credit restrictions

the endowment effect in games abstract in a laboratory experiment we study whether the endowment effect exists in a social and strategic context we employ a within subjects design whereby participants are asked for their willingness to accept wta or willingness to pay wtp to play a series of 2 2 games in the second part of the experiment we study the endowment effect in lotteries with the same payoffs as the games in the first part our findings provide robust evidence for the endowment effect both in games and in lotteries with the size of the effect actually being larger in games than in lotteries we also find that the endowment effect can partly be attributed to optimism

between preferences and references asymmetric price elasticities and the simulation of fiscal policies abstract canonical demand studies and fiscal policy simulations rest on the assumption that consumers react symmetrically to price increases and decreases such assumption has been challenged from both the empirical and theoretical points of view we propose theoretically consistent empirical specifications to estimate discrete choice models random utility dcm and continuous demand systems easi and aids demand systems that allow for reference prices and asymmetric own and cross price demand response our application focuses on the demand for sugar sweetened beverages in great britain using transaction level household purchase data and different product aggregation levels we find substantial evidence of asymmetric consumer response and loss aversion with a stronger response when prices rise above their reference level our results hold for both dcms on highly differentiated products and demand systems on aggregate product categories and are robust to alternative model and reference price specifications simulations of taxes and subsidies on soft drinks shows that ignoring asymmetry may lead to biases especially when predicting price cuts

dynamic hours of work functions for husbands wives and single females hours of work equations are derived from the constrained maximization of a utility function that is not separable over time and that varies with a household s demographic structure these equations are fitted to observations on wage rates nonlabor income and other variables for husbands wives and unmarried women the dependence of each household s current work and consumption behavior upon its work and consumption behavior in the past is examined closely and different interpretations of the relationship are confronted with the data

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

lifetime and annual marginal costs of redistribution in england sweden and the united states both the annual and lifetime marginal costs of redistribution in england sweden and the united states are calculated the annual marginal cost of redistribution is 2 90 in the united states 3 53 in england and 6 77 in sweden the lifetime marginal cost of redistribution is 4 46 in the united states and 7 96 in england the lifetime marginal cost of redistribution in sweden indicates that additional redistribution reduces the incomes of both the poor and nonpoor this study also shows that when there is greater income equality the marginal tax rate at which the incomes of the poor and nonpoor begin to be reduced will be at lower and lower levels copyright 1993 by mit press

do markets reveal preferences or shape them we contrast the proposition that markets reveal independently existing preferences with the alternative possibility that they may help to shape them using demand revealing experimental market institutions we separate the shaping effects of price cues from the effects of market discipline we find that individual valuations and prevailing prices are systematically affected by both exogenous manipulations of price expectations and endogenous but divergent price feedback these effects persist to varying degrees in spite of further market experience in some circumstances market experience may actually consolidate them we discuss possible explanations for these effects of uninformative price cues on revealed preferences

modelling the effectiveness of climate policies how important is loss aversion by consumers abstracts reliable decarbonisation policies can only be developed with a thorough understanding of how consumers choose between energy technologies current energy models assume optimal consumer decisions which may result in expectations of the effectiveness of climate policies that are far too optimistic prospect theory on the other hand aims to model real life choices based on empirical observations that losses have a relatively larger influence on decisions than gains relative to a reference point here we show for the first time how loss aversion can be included into a global energy model with high spatial resolution using heating technology uptake as a case study we simulate the future heating technology diffusion for 59 world regions covering the globe with and without the consideration of loss aversion we find that ignoring the implications of loss aversion overestimates the market uptake of renewables in individual countries as well as on the global level as a consequence loss aversion results in higher projected co2 emissions by households and the need for much stronger policy instruments for achieving decarbonisation targets in the case of residential heating a carbon tax of 200 tco2 is projected to reduce overall emission levels to a similar extent than a carbon tax of 100 tco2 without the consideration of loss aversion even for similar degrees of decarbonisation accounting for loss aversion implies substantial changes in the underlying technology composition technology choices become subject to a conservative shift towards low carbon technologies which are relatively less efficient but already more established in local markets

optimal dynamic carbon taxes in a climate economy model with distortionary fiscal policy how should carbon be taxed as a part of fiscal policy the literature on optimal carbon pricing often abstracts from other taxes however when governments raise revenues with distortionary taxes carbon levies have fiscal impacts while they raise revenues directly they may shrink the bases of other taxes e g by decreasing employment this article theoretically characterizes and then quantifies optimal carbon taxes in a dynamic general equilibrium climate economy model with distortionary fiscal policy first this article establishes a novel theoretical relationship between the optimal taxation of carbon and of capital income this link arises because carbon emissions destroy natural capital they accumulate in the atmosphere and decrease future output consequently this article shows how the standard logic against capital income taxes extends to distortions on environmental capital investments second this article characterizes optimal climate policy in sub optimal fiscal settings where income taxes are constrained to remain at their observed levels third this article presents a detailed calibration that builds on the seminal dice approach but adds features essential for a setting with distortionary taxes such as a differentiation between climate change production impacts e g on agriculture and direct utility impacts e g on biodiversity existence value the central quantitative finding is that optimal carbon tax schedules are 8 24 lower when there are distortionary taxes compared to the setting with lump sum taxes considered in the literature

optimal decisions for the loss averse newsvendor problem under cvar abstract most of the existing literature about the newsvendor problem mainly focused on choosing an optimal order quantity to maximize the expected profit of a risk neutral newsvendor however some studies pointed out that in practice managers decisions as to order quantities always deviate from the profit maximization order quantity which is referred to as decision bias in the newsvendor problem then many studies introduced other preferences rather than risk neutrality of the newsvendor to explain such a decision bias this paper thus introduces loss aversion to the research of the newsvendor decision bias we propose a new definition to the loss averse newsvendor problem legacy loss which is defined either as the loss for excess order or the shortage penalty for lost sales when sales time is due the optimal decisions of a loss averse newsvendor are obtained through the following three ways i minimizing the expected legacy loss ii minimizing cvar of legacy loss by combining the cvar measure in risk management iii minimizing the combination of expected legacy loss and cvar of legacy loss and are compared with other existing results besides we present some properties of the optimal decisions as well as relations among them some numerical examples are given to illustrate the obtained results

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

biased valuations damage assessments and policy choices the choice of measure matters abstract damages from for example an oil spill can be measured by how much people are willing to pay to avoid them or by the minimum compensation they demand to accept them and decisions to clean up can be justified by the willingness to pay to do it or by the compensation necessary to forgo it contrary to the usual official and unofficial conventions that the choice of measure is of no matter the empirical evidence and intuitions of most people strongly suggest otherwise the appropriate choice of measure appears to turn not on legal entitlements but on the reference state people use to judge negative and positive changes a criteria that is likely to call into question most estimates of the damages of increased health risks and the value of environmental mitigation efforts

steady state solutions of optimal tax mixes in an overlapping generations model abstract this paper analyzes steady state solutions of optimal tax mixes in an overlapping generations model of heterogeneous individuals with a utilitarian social welfare function a test with cobb douglas utility functions shows that an uneven distribution of the innate abilities leads to high rates of consumption and wage income taxes and a high level of a lump sum transfer the more the labor force works the higher the optimal tax on wage income significant differences in individual preferences lead to low rates of consumption and wage income taxes and to a high rate of interest income tax with identical preferences the rate of interest income tax is zero

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

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

tax revenue and the marginal cost of public funds in sweden abstract we assess the welfare cost of raising a marginal unit of tax revenue in a balanced budget general equilibrium framework the calculated social cost of an increment of public funds is sensitive to both the specific type of tax increase and the type of public spending used on the margin best guess assumptions on labor supply elasticities yield marginal costs of public funds for different fiscal mixes of between 0 67 and 4 51 at prevailing tax rates in sweden alternative labor supply assumptions well within the range of current estimates substantially affect the results and can imply infinite marginal welfare costs marginal welfare costs are also sensitive to assumptions about both the income and substitution effects of labor supply

deadweight losses and the saving response to a deficit deadweight losses and the saving response to a deficit several recent empirical studies have challenged the conventional wisdom that deficits cause a higher interest rate many economists are however critical of the seemingly implied theoretical justification that every individual fully recognizes the size of the deficit and the extent to which it increases future tax liabilities this paper demosntrates that far weaker information assumptions are needed to obtain an aggregate savings response equal to the deficit a reallocation of deadweight losses causes ricardians to save more than their share of the deficit to keep consumption unaffected allowing for a substantial fractrion of keynesians who save less than their share 1 introduction the saving behavior in the ricardian equivalence theorem is often criticized for relying on perfect foresight e g buchanan 1976 and evans 1985 85 even david ricardo himself rejected what is nowadays termed the ricardian equivalence theorem on grounds that people are not sufficiently aware of future tax liabilities see o driscoll 1977 this paper demonstrates that the saving response obtained by the ricardian equivalence theorem saving oing up by the deficit with a constant interest rate can be obtained with weaker rationality assumptions when deadweight losses associated with nonlump sum taxation are accounted for deadweight losses have been overlooked in the deficit debate possibly because the deadweight loss estimates in the public finance literature were rather small up until a few years ago the first mention of deadweight losses we have found is the brief theoretical discussion of transactions costs in collecting taxes and issuing debt in barro 1974 1109 deficits and welfare is an issue currently debated but the question posed is usually the reverse of the one asked here while we analyze how welfare losses affect the macro consequences of a deficit recent studies have focused on whether deficits increase or decrease welfare for instance both chan 1983 and barsky et al 1986 have studied whether deficits are desirable or not though analyzing how uncertainty of present and future after tax income are affected 1 futher a recent article by hansson and stuart 1987 estimated the losses from labor and capital taxes in a current and a future time period to evaluate the welfare consequences of a reallocation of taxes over time the theoretical argument made in this paper might be viewed as an obvious elaboration of the ricardian equivalence theorem nevertheless given current parameter estimates of deadweight losses the argument turns out to be very important quantitatively a simple illustration will demonstrate that far from everyone perhaps less than half of the population needs to have rational foresight about the deficit in order for a deficit to generate a one to one response in saving ii the behavior of ricardian individuals the effect of taxes altering efficiency and deadweight losses in each of the two time periods the standard ricardian equivalence theorem is arrived at assuming lump sum taxation with no deadweight losses accompanying taxation according to the theorem a deficit has the equivalent effect of current taxation because people anticipate the future tax liability incurred with the deficit these ricardian individuals have no reason to alter their labor supply the production techniques or their consumption pattern all that a deficit therefore results in is an increase in savings that is exactly equal to the deficit how would the analysis change if nonlump sum taxations is allowed for and associated with deadweight losses one shoudl have to analyze which particular tax is cut today and which is raised tomorow when the deficit is generated and how both affect the desired levels of labor suplly consumption etc today and in the future

quality perceptions and asymmetric switching between brands rotating indifference curves are used to induce an income effect that favors superior brands at the expense of inferior brands in a discrete choice model when calibrated on scanner panel data the model yields an objective measure of brand quality which is related to the rate of rotation the model also leads to asymmetric responses to price promotions where switching up to high quality brands is more likely than switching down the model is capable of nesting the standard logit model and is similar to a nested logit model when there exists clusters of brands of like quality the model is used to explore a product line pricing decision where profits are maximized subject to the constraint that consumer utility is maintained

differentiated price loss aversion in destination choice the effect of tourists cultural interest abstract this article looks into the differentiated effects of loss aversion depending on whether individuals show cultural interest when choosing a destination based on the fact that perceived value implies not only sacrifices but also the expectations of a certain level of quality and prospects of satisfaction together with the idea the prospect theory applies to tourism prices the article states the hypothesis that interest in culture when choosing a destination lowers people s loss aversion by incorporating the reference dependent model into a multinomial logit model with random parameters which controls for heterogeneity the empirical application shows that culture interested tourists are less loss averse i e the negative effect of finding a higher than expected price diminishes with cultural interest the expectation of enjoyment of these attributes and the more conscious attitude toward maintenance restoration activities of cultural sites are hypothesized to lead prices to be evaluated differently when selecting a destination

asymmetric competition in choice and the leveraging of competitive disadvantages studies of grocery sales show that consumers of store brands switch to price discounted national brands more than consumers of national brands switch to discounted store brands such asymmetric price competition can be explained with numerous mechanisms proposed here and elsewhere we report a choice experiment that replicates asymmetric price competition favoring higher quality competitors and demonstrates asymmetric quality competition favoring lower quality competitors also demonstrated are multiple mechanisms contributing to competitive asymmetries where dominance involving the otherwise preferred brand is particularly potent e g when a higher quality competitor matches the price of an otherwise preferred lower quality brand the findings implicate modifications to 1 theories of decision making when extended to repeat choice 2 empirical models of secondary purchase data and 3 strategies for positioning and attacking brands whereas improving competitive disadvantages often attracts consumers from competitors more than does improving competitive advantages this benefit must be weighed against the differentiation sacrificed by improving competitive disadvantages improving competitive advantages in contrast increases differentiation

are the disabled less loss averse evidence from a natural policy experiment i introduction a large literature points to differences in cognitive bias among diverse populations according to lunn and lyons 2010 lower income less educated and older populations are more prone to decision making that deviates from economic rationality also see mather et al 2012 and tymula et al 2013 however as discussed by lunn and lyons 2010 little is known about the decision making biases of other vulnerable populations notably the physically disabled or implications thereof for their economic well being in this study we examine differences in cognitive bias and behavioral heuristics among nondisabled and physically disabled populations specifically using data from a unique israeli government natural policy experiment we assess loss aversion among nondisabled and disabled populations in the decision to purchase a home our empirical tests are motivated by previous findings in physiology and psychology showing that disabled persons often develop physical and mental mechanisms to help compensate for disabilities according to bishop 2005 disabled persons utilize such coping mechanisms to minimize gaps caused by their impairments as further suggested by devins et al 1983 yoshida 1993 livneh and antonak 1997 and bishop and feist price 2002 such strategies and mechanisms allow disabled persons increased control over their health and environment specifically nirje 1972 sands and wehmeyer 1996 and wehmeyer 1998 suggest that disabled populations seek compensatory mechanisms to enhance autonomy efficacy self reliance and self management among noteworthy examples cattaneo and vecchi 2011 summarize a long series of studies indicating the development of compensatory mechanisms among visually impaired persons results of those analyses indicate enhanced nonvisual perceptual sensorial and cortical level abilities among the visually disabled e g amedi et al 2003 crawford et al 2008 hamilton pascual leone and schlaug 2004 hull and mason 1995 muchnick et al 1991 roder rosier and neville 2001 niemeyer and starlinger 1981 in other recent work keysar hayakawa and an 2012 provide evidence of compensatory cognitive mechanisms among persons with language impairments results of experimental analysis indicate diminished decision biases and reduced loss aversion among non native language speakers the authors hypothesize that use of a foreign language reduces the opportunity for spontaneous response and results in a more consciously measured and considered mode of thinking 1 as with visually or language impaired persons the compensatory mechanisms acquired by physically disabled persons may extend beyond the psychophysiological domain to include cognitive adjustments indeed as discussed by stanovich and west 2000 lower levels of cognitive bias could compensate for physical disability and provide for improved coping prospects over the past decade the israeli government sought to privatize public housing via an offer to sell rental units to tenants at a discount from the market price the algorithms utilized by the government to determine the magnitudes of the price reductions varied over time furthermore the price reductions were not forecastable among targeted program participants tenants had the opportunity to either accept or decline government sales offers extended at each successive program iteration our research employs survival analysis to specify and empirically test whether physically nondisabled and disabled tenants exhibited different degrees of loss aversion behavior in their home purchase decisions 2 as first described by kahneman and tversky 1979 loss aversion pertains to household behavior when the aggravation that one experiences in losing a sum of money appears to be greater than the pleasure associated with gaining the same amount p 279 in experimental work tversky and kahneman 1992 find that under even odds for winning and losing the gain should be at least twice as large as the loss for a prospect to be acceptable whereas putler 1992 finds for example that consumers are two and a half times more responsive to price increases that are in excess of the reference price than they are to comparable price declines

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 endowment effect and the reference state evidence and manipulations abstract recent reports suggest that the endowment effect may be due to conditions under which it is observed and explained by incentives long recognized in standard theory evidence from new experiments reported here provides empirical support for the role of the economic environment on people s perceived reference state and consequently on their valuations as suggested by koszegi and rabin koszegi b rabin m 2006 a model of reference dependent preferences quarterly journal of economics 121 1133 1165 and indicates that the disappearance of the valuation disparity is more likely due instead to conditions that weaken the perception of reference states further these conditions appear to be poor approximations of those that prevail in most cases for which valuations are normally made

the welfare cost of capital income taxation in a growing economy the welfare cost of capital income taxation is analyzed in a general equilibrium framework where the private sector is represented by a competitive household endowed with perfect foresight and an infinite life the value of the welfare cost depends essentially on the elasticity of substitution between capital and labor in the production function numerical estimates are presented for different values of the parameters of the model the welfare gain obtained by the abolition of the capital income tax is smaller when the private sector is not endowed with perfect foresight it is reduced by about 40 percent when expectations are myopic the allocation efficiency cost of the corporate tax dwarfs the intertemporal welfare cost

on the consistency of backward looking expectations the case of the cobweb in dynamic models of economic fluctuations backward looking expectations with systematic forecasting errors are inconsistent with rational behaviour in non linear dynamic models exhibiting seemingly unpredictable chaotic fluctuations however simple habitual rule of thumb backward looking expectation rules may yield non zero but nevertheless non systematic forecasting errors in a chaotic model expectational forecasting errors may have zero autocorrelations at all lags even for rational agents patterns in these forecasting errors may be very difficult to detect especially in the presence of small noise backward looking expectations are then not necessarily inconsistent with rational behaviour we investigate whether simple expectation schemes such as naive or adaptive expectations can be consistent with rational behaviour in the simplest of all non linear dynamic economic models the non linear cobweb model

adaptive learning and roads to chaos the case of the cobweb abstract we investigate the dynamics of the cobweb model with adaptive expectations a linear demand curve and a nonlinear s shaped increasing supply curve both stable periodic and chaotic price behaviour can occur we investigate how the dynamics of the model depend on the parameters both infinitely many period doubling and period halving bifurcations can occur when the demand curve is shifted upwards the same result holds with respect to the expectations weight factor

reducing co2 emissions under fiscal retrenchment a multi cohort cge model for austria the stabilization of budget deficit and budget debt ratios by fiscal retrenchment in order to fulfill the maastricht criteria for the emu is of central focus in most eu countries at the same time the national policy dimension of acute environmental problems such as global warming has receded in the public eye the environmental dimension nonetheless remains urgent and a re evaluation of the prospects of co2 policy is needed against the background of fiscal retrenchment required by supranational obligations we shall do this for the small open austrian economy by constructing a dynamic multi cohort cge model enabling us to assess quantitatively the lifetime welfare impacts on the cohorts affected by three different options for using co2 permit revenues the distribution of welfare costs of toronto co2 policy across cohorts significantly differs with use this is explained by income inheritance and price effects

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

hysteresis price acceptance and reference prices the existence of price thresholds in grocery retailing is well documented most authors explain the existence of price thresholds using assimilation contrast theory adaptation level theory or prospect theory however each of these theories is untenable if consumers are believed to behave rationally we offer a theoretical explanation grounded in real options theory rot and economic hysteresis we test the rot hypothesis against three plausible alternatives using a maximum likelihood friction model that we augment for unobserved heterogeneity our findings support the rot hypothesis and suggest that the existence of price thresholds in aggregate data are driven by a common recognition of real option values which do not disappear with the inclusion of consumer heterogeneity

current account effects of a temporary change in government expenditure a perfect foresight model of intertemporal utility maximization is used to analyze the current account effects of a temporary increase in government spending the relationship between the marginal utility of private consumption and the supply of public goods in the economy is shown to play a crucial role in determining the qualitative nature of the optimal current account response the link between the timing of the policy change and the magnitude of the current account effect is also examined

looming losses in future time perception abstract it is proposed that a future time interval s perceived length will be affected by whether the interval ends with a gain or loss confirming this several experiments indicate that consumers perceive intervals ending with losses as shorter than equivalent intervals ending with gains the authors explore the mechanisms underlying these effects and they identify several parallels between the current effects and loss aversion the authors further show that these changes in time perception influence consumption decisions and they consider the implications of the findings for theories of time perception and intertemporal choice

the rotterdam demand model and its application in marketing this paper shows how the system wide approach to demand analysis can be utilized in marketing in the context of the rotterdam model we describe how the approach can be applied to narrowly defined groups of goods such as beer wine and spirits to estimate income and price elasticities of demand the paper also provides extensions to deal with advertising and introduces a new way of identifying market structure

values of gains and losses reference states and choice of measure the available empirical evidence continues to suggest that people commonly value losses more and often much more than otherwise commensurate gains consequently current practice of using the wtp measure for all changes is often likely to lead to misleading assessments of welfare changes the reference dependence of preferences implies instead that while the wtp measure is appropriate for gains the value of both positive and negative changes in the domain of losses will usually be more accurately assessed with the wta measure
