the distributional implications of asymmetric income dynamics abstract income dynamics differ between groups of households defined by whether the head has university education or not and have changed asymmetrically in great britain since 2008 using a heterogeneous agent incomplete markets model we examine the quantitative implications of these differences for wealth inequality and for the distribution of conditional welfare losses within group wealth inequality is higher for the non university group and has increased since 2008 for both groups while between group inequality has also increased welfare losses are significantly higher for the non university educated since 2008 and are driven by both a greater fall in mean income and a larger rise in income risk non university educated households which had initial wealth below the median and net labour income in the lower quintiles suffered bigger losses social insurance policies beyond those currently in place can mitigate such welfare losses via tax and benefit redistributive mechanisms for the broad majority of households social insurance is valued more when it insures against the big adverse income shocks

an impossibility theorem for wealth in heterogeneous agent models with limited heterogeneity abstract it has been conjectured that canonical bewley huggett aiyagari heterogeneous agent models cannot explain the joint distribution of income and wealth the results stated below verify this conjecture and clarify its implications under very general conditions we show in particular that if i agents are infinitely lived ii saving is risk free and iii agents have constant discount factors then the wealth distribution inherits the tail behavior of income shocks e g light tailedness or the pareto exponent our restrictions on utility require only that relative risk aversion is bounded and a large variety of income processes are admitted our results show conclusively that it is necessary to go beyond standard models to explain the empirical fact that wealth is heavier tailed than income we demonstrate through examples that relaxing any of the above three conditions can generate pareto tails

wealth distribution with random discount factors abstract to explain the pareto tail behavior empirically observed in wealth distributions the quantitative macro literature has occasionally assumed that agents have random discount factors this paper formally proves that the stationary wealth distribution in a simple huggett model with random discounting has power law tails and characterizes the pareto exponents analytically i find that in general there is no clear relationship between the return on wealth and inequality and that the pareto exponent is highly sensitive to the persistence of the discount factor process i also provide a practical guidance for how to characterize the pareto exponents in richer models

quality uncertainty search and advertising consumers in this paper we begin to remedy this omission by developing a formal model that shows how risk affects the decisions of riskaverse consumers regarding the amount of search and whether or not to buy advertised products we incorporate risk into the model by assuming that consumers are concerned not only with expected product quality but also with the amount of variation that exists across the qualities available the risk arises not because the quality is itself variable but rather because there is variation in quality across products and consumers cannot evaluate the quality of a particular brand before purchase we consider two sources of information about quality both of which are costly to consumers firms supply consumers with implicit quality signals through advertisements that convey only that a product is advertised but not direct information about the quality of the product and consumers supply themselves with direct quality information through search these methods affect both the expected value of quality received and its riskiness we analyze search and advertising simultaneously in order to model the consumers substitution of one information source for the other we then use the model to show how firms may use advertising as an implicit signal that advertised products are less risky than unadvertised products and to explain why information is primarily provided by firms in some markets whereas in other markets consumers acquire their information through search in addition to explicitly considering risk our model has several other attributes that distinguish it from the extant search literature in order to obtain a meaningful market equilibrium we construct a full partial equilibrium model in which the behavior of both buyers and sellers is examined and the distribution of qualities in the market is endogenously determined this approach is used

cultural industries in international business research progress and prospect cultural industries systems of organizations that produce and distribute cultural goods with substantive symbolic aesthetic or artistic value represent an important exciting and complex context that receives growing scholarly attention as the first review of management research on cultural industries this paper aims to provide a systematic synthesis of current research summarizing distinctive characteristics of cultural industries and highlighting research gaps we also illustrate how the unique nature dynamics and evolution of cultural industries provide opportunities to broaden international business theories in four research themes i e internationalization strategy cross border innovation social inclusion in the global economy and emerging market research

profit maximizing perceptual positions an integrated theory for the selection of product features and price an important component of marketing strategy is to position a product in perceptual space but to realize a perceptual position we must model the link from physical characteristics to perceptual dimensions and we must use this model to maximize profit this paper integrates psychological theories on how consumers process information with economic models and psychometric measurement and it develops a theory for selecting physical features and price to achieve a profit maximizing perceptual position the theory begins with a lancaster like transformation from goods space to characteristics space and investigates the implications of a mapping to a third space perceptual space we show that all products efficient in perceptual space must be efficient in characteristics space but not conversely but consumers vary in their preference and the way they perceive products thus we introduce distributional components to the theory and derive both geometric and analytic methods to incorporate this consumer heterogeneity next we investigate costs and derive a perceptual expansion path along which a profit maximizing position must exist conjoint analysis and quantal choice models provide the measurements to implement the theory the theory is illustrated with a hypothetical example from the analgesics market and some of the potential psychometric measurements are illustrated with an empirical application in the communications market

country of origin effects for uni national and bi national products this study examines the effects of country of origin and brand name cues on consumer evaluations of uni national and bi national products and estimates the perceived values of such cues from personal interviews with a regional quota sample of household residents the study found the salience of country of origin in product evaluations under within subject experimental design finally managerial implications are discussed in regards to international branding and sourcing strategies

brand popularity country image and market share an empirical study this study examines how brand popularity in conjunction with other marketing variables influences market share directly as well as indirectly by interacting with country related intangible assets or simply country image the results of our empirical analysis show that a competitive analysis without the recognition of country image would be misleading we found that country specific intangible assets exist and that they significantly interact with marketing variables differently for u s and japanese brands in the subcompact car market in the usa brand popularity and advertising were found to be key factors for intangible assets for both the u s and the japanese brands brand popularity was the most significant factor for market share in both the short run and the long run japanese firms direct investment fdi in the target country directly influenced market share only in the short run several important implications for international marketing are presented

the estimation of demand parameters in hedonic price models this paper shows that the econometric problem of estimating hedonic demand parameters is not a standard identification problem caused by demand supply interaction as has been often assumed estimation procedures based on this assumption lead to biased results the hedonic estimation problem is instead caused by the endogeneity of both prices and quantities when households face a nonlinear budget constraint an instrumental variables solution to this problem is suggested using instruments that exogenously shift the budget constraint

defensive marketing strategies this paper analyzes how a firm should adjust its marketing expenditures and its price to defend its position in an existing market from attack by a competitive new product our focus is to provide usable managerial recommendations on the strategy of response in particular we show that if products can be represented by their position in a multiattribute space consumers are heterogeneous and maximize utility and awareness advertising and distribution can be summarized by response functions then for the profit maximizing firm it is optimal to decrease awareness advertising it is optimal to decrease the distribution budget unless the new product can be kept out of the market a price increase may be optimal and even under the optimal strategy profits decrease as a result of the competitive new product furthermore if the consumer tastes are uniformly distributed across the spectrum a price decrease increases defensive profits it is optimal at the margin to improve product quality in the direction of the defending product s strength and it is optimal at the margin to reposition by advertising in the same direction in addition we provide practical procedures to estimate 1 the distribution of consumer tastes and 2 the position of the new product in perceptual space from sales data and knowledge of the percent of consumers who are aware of the new product and find it available competitive diagnostics such as the angle of attack are introduced to help the defending manager this article was originally published in marketing science volume 2 issue 4 pages 319 360 in 1983

international lending and borrowing in a stochastic stationary equilibrium this paper develops a simple general equilibrium model of international borrowing and lending in which national products are subject to random fluctuations international capital flows arise from the efforts of risk averse households in different countries to self insure against random income fluctuations by accumulating foreign claims that can be used to finance a less variable profile of consumption relative to national income in the absence of aggregate uncertainty a stationary rational expectations equilibrium is shown to exist despite the fact that rates of time preference differ among countries a number of results many of which enrich those in the existing literature are obtained copyright 1990 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

measuring market efficiency and welfare loss this study presents a general methodology capable of addressing a number of fundamental questions in consumer policy are consumers paying more than the minimum price for a given bundle of attributes if so what brands cost more than the consumer needs to pay what would be the degree of improvement in the consumer s well being if some intervention sets the price of such inefficient brands at the efficient level we apply the methodology to data on atuomobiles and several other goods and analyze the determinants of efficiency

who is behavioral cognitive ability and anomalous preferences in this paper we ask whether variation in preference anomalies is related to variation in cognitive ability evidence from a new laboratory study of chilean high school students with similar schooling backgrounds shows that small stakes risk aversion and short run discounting are less common among those with higher standardized test scores the relationship with test scores survives controls for parental education and wealth we find some evidence that elementary school gpa is predictive of preferences measured at the end of high school two laboratory interventions provide suggestive evidence of a possible causal impact of cognitive resources on expressed preferences jel j24 d14 c91

existence of stationary equilibrium in an incomplete market model with endogenous labor supply in this article i first study an income fluctuation problem with endogenous labor supply let be the agent s time discount factor and r 0 be the constant gross rate of return on assets for r 1 i show that the agent s wealth either approaches infinity almost surely or converges to a finite level almost surely for r

robust comparative statics in large dynamic economies we consider infinite horizon economies populated by a continuum of agents subject to idiosyncratic shocks this framework contains models of saving and capital accumulation with incomplete markets in the spirit of works by bewley aiyagari and huggett models of entry exit and industry dynamics in the spirit of hopenhayn s work and dynamic models of occupational choice and search models as special cases robust and easy to apply comparative statics results are established with respect to exogenous parameters as well as various kinds of changes in the markov processes governing the law of motion of the idiosyncratic shocks

random earnings differences lifetime liquidity constraints and altruistic intergenerational transfers abstract this paper develops a model of private savings behavior in which households care about their descendants cannot have negative net worth and have lifetime earnings depending on random draws from an exogenous distribution of abilities the elements interact very lucky parents are likely to leave large estates constrained children are unusually likely to receive intergenerational transfers the paper proves the existence of a stationary cross sectional distribution of wealth endogenously determines where liquidity constraints will bind and shows that the long term interest rate must be such that ricardian neutrality fails its last section generates several illustrative numerical simulations

note competitive price and positioning strategies brand positioning and brand pricing are important strategic decisions for marketing managers such decisions are interrelated and depend upon competitive brand positions and prices however any unilateral decisions may encourage repositioning and price adjustment by competitors thus leading to either new market equilibria or a price positioning war this paper examines such price and positioning decisions in a competitive environment by extending the defender consumer model to more complex equilibria we assume that the brands are already in the market and that positions are sticky in the sense that brands cannot leapfrog one another among the insights for such incumbent brands are if prices are symmetric and held constant firms seek to reposition toward the center of the market but price advantages by central firms can mediate that central tendency such that an equilibrium exists with positive profits if brand positions are held constant the nash equilibria for prices exist and are unique and category profits the sum of brand profits are maximized for maximum brand differentiation for two and three brand markets the subgame perfect nash equilibrium where positioning decisions are made with foresight on the price equilibria causes firms to unilaterally seek maximum brand differentiation but for four or more brands greater foresight and or cooperation appears necessary to reach the point of maximum brand differentiation these results apply where the defender consumer model is an exact description of consumer response and where the competitive reaction assumptions hold in any empirical situation such forces might be softened resulting in differentiated but not maximally differentiated brands

saving and liquidity constraints this paper is concerned with the theory of saving when consumers are not permitted to borrow and with the ability of such a theory to account for some of the stylized facts of saving behavior the models presented in the paper seem to account for important aspects of reality that are not explained by traditional life cycle models copyright 1991 by the econometric society

matching product catgeory and country image perceptions a framework for managing country of origin effects the study of country of origin coo effects examines how consumers perceive products emanating from a particular country this study examines coo in terms of the fit between countries and product categories a framework is suggested which matches the importance of product category dimensions with the perceived image of the country of origin along the same dimensions such matches or mismatches can be either favorable or unfavorable managers can use product country match information to assess consumers purchase intentions and assist them in managing their product s coo data collected from consumers in ireland mexico and the united states demonstrate the product country match framework and its strategic implications

customer evaluation of products in a global market marketing scholars interest in the influence of source countries on product evaluations has intensified during the past twenty five years as this research tradition has evolved the literature has gradually gained more depth and sophistication nevertheless research in this area lacks a common conceptual framework furthermore research priorities with regard to the role of this area of inquiry within the broader field of consumer behavior marketing and general business decisions have not been made clear this article rationalizes the buying decision processes within the context of source country influences and offers a conceptual framework for further development in addition it links country level considerations to firm level decisionmaking thus providing a foundation for meaningful managerial decisions

on the existence and uniqueness of stationary equilibrium in bewley economies with production abstract i prove existence of stationary recursive competitive equilibrium in bewley economies with production under specifications in which i the utility function is allowed to be unbounded and ii the underlying discrete idiosyncratic productivity process can take any form aside from mild restrictions some of the intermediate results provide theoretical basis for assumptions often made in the quantitative macroeconomics literature by providing an example i illustrate that the equilibrium is not necessarily unique even under typical specifications of the model and discuss the underlying reasons for multiplicity

non existence of recursive equilibria on compact state spaces when markets are incomplete abstract this paper analyzes one good exchange economies with two infinitely lived agents and incomplete markets it is shown that there are no recursive markov equilibria for which borrowing debt constraints never bind if the state space of exogenous and endogenous variables is a compact subset of r n moreover for large enough but finite borrowing limits no recursive equilibrium with compact state space exists these non existence results hold for any economy satisfying the following standard assumptions preferences are additively separable across time and states the one period utility function is time and state independent and unbounded from below endowments are bounded and follow a markov chain with stationary transition matrix there is some idiosyncratic risk and no aggregate risk

recursive equilibria in an aiyagari style economy with permanent income shocks in this paper we prove the existence of a recursive competitive equilibrium rce for an aiyagari style economy with permanent income shocks and perpetual youth structure we show that there exist equilibria where borrowing constraints are never binding this allows us to establish a non trivial lower bound on the equilibrium interest rate to solve the individual s problem we present a new approach that uses lattices of consumption functions to deal with the non compact state space and the unbounded utility function the approach uses only the first order conditions of the problem euler equations the proof is constructive and it serves as a theoretical foundation for the convergence of a policy function iteration procedure

incomplete markets labor supply and capital accumulation we explore the accumulation of capital in the presence of limited insurance against idiosyncratic shocks borrowing constraints and endogenous labor supply in the exogenous labor supply case e g aiyagari 1994 huggett 1997 the presence of limited insurance increases the demand for savings for precautionary reasons as a consequence capital and output are higher under incomplete markets we show that if labor hours are endogenous labor supply is likely to be lower under incomplete markets because those agents who experience a high shock to productivity are ex post richer and they work fewer hours in some cases this wealth effect can overcome the aggregate precautionary savings and give rise to lower savings and output under incomplete

huggett economies with multiple stationary equilibria abstract i obtain a closed form solution to a huggett economy with constant absolute risk aversion cara utility when the vector of individual state variables follows a var 1 process with an arbitrary shock distribution the stationary equilibrium is unique if the income process is ar 1 but not necessarily so otherwise with gaussian shocks i provide general sufficient conditions for the existence of at least three equilibria when the income process is either arma 1 1 ar 2 or has a persistent transitory pt representation with negatively correlated shocks the possibility of multiple equilibria calls for caution in comparative statics exercises and policy analyses using heterogeneous agent models as an illustration i provide an example in which the welfare implication of changing the income risk goes in opposite directions depending on the choice of equilibrium

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

income and wealth heterogeneity in the macroeconomy how do movements in the distribution of income and wealth affect the macroeconomy we analyze this question using a calibrated version of the stochastic growth model with partially uninsurable idiosyncratic risk and movements in aggregate productivity our main finding is that in the stationary stochastic equilibrium the behavior of the macroeconomic aggregates can be almost perfectly described using only the mean of the wealth distribution this result is robust to substantial changes in both parameter values and model specification our benchmark model whose only difference from the representative agent framework is the existence of uninsurable idiosyncratic risk displays far less cross sectional dispersion and skewness in wealth than u s data however an extension that relies on a small amount of heterogeneity in thrift does succeed in replicating the key features of the wealth data furthermore this extension features aggregate time series that depart significantly from permanent income behavior

the effect of interest rates on consumption in an income fluctuation problem abstract we examine the effect of a change in interest rates on an agent s consumption and savings decisions when her income is fluctuating in each period a long lived agent decides how much to save i e invest in a risky bond and how much to consume while her income and the rate of return on her savings are uncertain and depend on the state of the economy we show that under the concavity of the consumption function a condition that ensures that the substitution effect dominates the income effect lower interest rates encourage the agent s consumption across all states

a comparative evaluation of multiattribute consumer preference models in this paper the theory and estimation procedures for several consumer preference models are discussed predictive accuracy in the form of internal consistency of these models is compared in an empirical application consumer decision situations are classified into two classes decisions under certainty and decisions under uncertainty for each of the two classes of decision situations two modeling strategies have been used statistical estimation and algebraic solution an additive conjoint an additive and a multiplicative measurable value and an additive and a multiplicative utility model are considered our main finding is that the statistical estimation procedures outperform their algebraic counterparts on the criterion of predictive accuracy the utility model provides better predictions for decisions under uncertainty than the widely used conjoint models the relationship between models for decisions under certainty and decisions under uncertainty is discussed it is shown how a conjoint or a mea

on income fluctuations and capital gains abstract we consider the infinite time horizon problem of asymptotically maximizing the expected accumulated discounted utility in a one good production economy the available capital in a given period is given by the production of the previous period plus a random variable the product of the discount and interest factors is either 1 greater than or 2 equal to one under 1 the optimal policy exists under certain conditions and always under 2 the optimal capital sequence almost surely goes to infinity under 1 with conditions on the utility one almost surely reaches a capital level above which the sequence is increasing

brand origin recognition accuracy its antecedents and consumers cognitive limitations an ever growing literature has reported consumer bias toward national origins of products and has explored factors that moderate such bias researchers have assumed if only tacitly that consumers are knowledgeable of brand origins and that this knowledge is a significant influence that drives judgments of product quality brand attitudes and choice behavior in the marketplace using categorization theory and attribute diagnosticity as the theoretical foundation our research reveals that consumers actually have only modest knowledge of the national origins of brands and that american consumers proficiency at recognizing foreign brand origins is predicted by variables such as socioeconomic status past international travel foreign language skills and gender in the second of two studies we determined that brand origin recognition is based largely on consumers associations of brand names with languages that suggest country origins these studies ultimately lead us to conclude that past research has inflated the influence that country of origin information has on consumers product judgments and behavior and its importance in managerial and public policy decisions

willingness to pay and willingness to accept how much can they differ comment i agree with the point made by edoh y amiran and daniel a hagen 2003 that there can be a substantial or even infinite divergence between the wta and wtp for a public good even where there is a nonzero elasticity of substitution between market goods and the public good provided that the indifference curves are asymptotically bounded with respect to market goods in the manner they describe this is an important point they are also correct to point out that the elasticity of substitution is a local concept whereas their asymptotic boundedness condition applies also for discrete changes my 1991 paper used a local analysis because it was following the structure of the analysis in robert d willig 1976 and alan randall and john r stoll 1980 i wanted to show that while randall and stoll appeared to extend willig s local result on wta versus wtp from price changes to changes in the quantity of a public good the relevant elasticity was in fact different and involved the substitution elasticity as well as the income elasticity i view these points by amiran and hagen as not two separate results but essentially the same result their asymptotic boundedness condition generalizes my zero elasticity of substitution condition to discrete changes the asymptotic boundedness condition can be expressed as follows assuming a bivariate utility function u x q and given a reference point x q associated with a reference utility level u u x q there exists some q q such that for all q q there exists no x such that u x q u in other words no amount of x can substitute for the reduction in public good from q to q q in the case of a zero elasticity of substitution q q but as amiran and hagen show in their theorem 1 this is unnecessarily restrictive when dealing with a discrete reduction in q furthermore their theorem 2 can be viewed as a special case of their theorem 1 in which q 0 which makes q an essential commodity it is well known in consumer theory that the wta to avoid the loss of an essential market good is infinite their theorem 2 extends this result to the case of an essential nonmarket good but as their theorem 1 shows essentialness is not necessary for an infinite wta the boundedness condition is the key and this implies a fundamental lack of substitutability between money market goods and the public good

the willingness to pay willingness to accept gap a failed replication of plott and zeiler abstract the well known willingness to pay willingness to accept wtp wta gap refers to the observation that individuals attach a higher value to objects they own wta than to objects they do not own wtp we report on experiments to re investigate the possibility that the wtp wta gap arises from subject misconceptions due to experimental procedures as suggested by plott and zeiler 2005 the contribution of this paper is two fold first we attempt to replicate the findings by plott and zeiler that the wtp wta gap disappears when using procedures that are aimed at reducing misconceptions such as extensive training and practice rounds for the bdm mechanism however we fail to do so as the wtp wta gap persists in the main task where subjects state their wta or wtp for a mug second we use the paid practice rounds to identify subjects without apparent misconceptions and find that also for those subjects who never make dominated choices in the lottery tasks the wtp wta gap in the mug task exists thus we find no evidence of the idea that subject misconceptions are the main source of the wtp wta gap

consumption liquidity constraints and asset accumulation in the presence of random income fluctuations recent empirical research flavin 1981 hagashi 1982 has rejected the certainty equivalent formulation of permanent income hypothesis hall 1978 these findings are often attributed to households inability to borrow completely against expected future labor income this paper is a theoretical investigation of optimal consumption behavior under risk aversion random income fluctuations and borrowing restrictions our principle objective is to establish the existence and to investigate the properties of the stationary probability distribution which characterizes the asymptotic behavior of consumption under these conditions this abstract was borrowed from another version of this item

exchange asymmetries incorrectly interpreted as evidence of endowment effect theory and prospect theory systematic asymmetries in exchange behavior have been widely interpreted as support for endowment effect theory an application of prospect theory positing that loss aversion and utility function kinks set by entitlements explain observed asymmetries we experimentally test an alternative explanation namely that asymmetries are explained by classical preference theories finding influence through the experimental procedures typically used contrary to the predictions of endowment effect theory we observe no asymmetries when we modify procedures to remove the influence of classical preference theories when we return to traditional type procedures however the asymmetries reappear the results support explanations based in classical preference theories and reject endowment effect theory

the wealth distribution in bewley economies with capital income risk abstract we study the wealth distribution in bewley economies with idiosyncratic capital income risk we show analytically that under rather general conditions on the stochastic structure of the economy a unique ergodic distribution of wealth displays a fat tail

learning to like what you have explaining the endowment effect the endowment effect describes the fact that people demand much more to give up an object than they are willing to spend to acquire it the existence of this effect has been documented in numerous experiments we attempt to explain this effect by showing that evolution favors individuals whose preferences embody an endowment effect the reason is that an endowment effect improves one s bargaining position in bilateral trades we show that for a general class of evolutionary processes strictly positive endowment effects will survive in the long run

multinational production effect on brand value direct foreign investment in manufacturing abroad has a number of consequences for the firm one aspect particularly salient when the company s image is tied to its home country is the impact of the dfi upon customer perceptions of the brand the present study shows how changes in perceptions can be assessed prior to the investment decision and how the brand value consequences of a particular location can be estimated the proposed method is illustrated using data from a japanese company s entry into the u s

endogenous partial insurance and inequality in this paper we propose a model of endogenous partial insurance and we investigate its implications for macroeconomic outcomes such as wealth inequality asset accumulation interest rate and consumption smoothing to this end we include participation costs to state contingent asset markets into an otherwise standard aiyagari 1994 model we highlight the resulting nonmonotonic relationship between wealth and insurance market participation when insurance is costly poor households remain uninsured middle class households participate in the insurance market whereas rich households decide to self insure by only purchasing risk free assets after theoretically characterizing the endogenous partial insurance equilibrium we quantify its effect emphasizing the roles of a participation channel and an interest rate channel

a cross cultural study of made in concepts cross cultural studies of the perceptions of countries of origin by industrial users have been few but they are important because of their managerial implications for multinational firms this study uses data obtained from american and french directors of purchasing of major industrial firms concerning their perceptions of 5 major made in concepts after the data were corrected for response bias results show both how the respondents perceive the made in concepts and the differences between the american and french perceptions

aggregate precautionary savings when is the third derivative irrelevant abstract when are aggregate precautionary savings positive we address this question in the context of a general equilibrium model where infinitely lived agents receive idiosyncratic labor endowment shocks hold a risk free asset to smooth consumption and face a liquidity constraint we prove that 1 the steady state capital stock is always larger in any equilibrium with idiosyncratic shocks and a liquidity constraint than without idiosyncratic shocks i e aggregate precautionary savings are positive as long as consumers are risk averse and 2 aggregate precautionary savings occurs if and only if the liquidity constraint binds for some agents

the risk free rate in heterogeneous agent incomplete insurance economies abstract why has the average real risk free interest rate been less than one percent the question is motivated by the failure of a class of calibrated representative agent economies to explain the average return to equity and risk free debt i construct an economy where agents experience uninsurable idiosyncratic endowment shocks and smooth consumption by holding a risk free asset i calibrate the economy and characterize equilibria computationally with a borrowing constraint of one year s income the resulting risk free rate is more than one percent below the rate in the comparable representative agent economy

international product positioning one of the cornerstones of a firm s marketing strategy in any market is the development of an appropriate product positioning plan this paper argues that may of the same considerations that go into the positioning strategy in the home country are directly relevant for international markets there is an added elements of complexity in that the country of origin of the imported product will often be a salient factor in the buyer evaluation process the effect of country stereotype will be to shift the position of the product in the perceptual space and alter the overall evaluation of its merits the competitive strength of the product will thus be affected by country biases the paper shows how these factors can be dealt with in the management of the international product positioning task

when do borrowing constraints bind some new results on the income fluctuation problem abstract the empirical failure of the permanent income hypothesis has prompted researchers to investigate models in which consumers are liquidity constrained as shown in deaton econometrica 59 5 1991 1221 liquidity constrained consumers might choose to exhaust their borrowing capacity from time to time yet due to technical limitations the conditions under which this behavior arises have not been investigated the present paper extends the class of solvable models in a way that allows this issue to be dealt with it turns out that under the loosest sustainable borrowing constraint the agent might systematically avoid exhausting his borrowing capacity

hedonic prices and implicit markets estimating demand and supply functions for differentiated products in choosing the level of quality to purchase the buyer of a differentiated product also chooses a point on the marginal price schedule for that product hence in general the demand functions for product characteristics cannot be consistently estimated by ordinary least squares market equilibrium results in a matching of characteristics of demanders and suppliers this matching restricts the use of buyer and seller characteristics as instruments when estimating demand and supply functions for product characteristics the paper develops these issues a stochastic structure for hedonic equilibrium models is then proposed identification results are presented and estimation procedures are outlined

strategic loan defaults and coordination an experimental analysis this paper experimentally studies the impact of bank and borrower fundamentals on loan repayment we find that solvent borrowers are more likely to default strategically when the bank s expected strength is low although loan repayment is a pareto dominant nash equilibrium borrowers are also less likely to repay when other borrowers expected repayment capacity is low regardless of banks fundamentals we show that changes in expectations about bank and borrower fundamentals change the risk dominance properties of the borrowers coordination problem and that these changes subsequently explain strategic defaults for the individual borrower loss aversion and negative past experiences reduce repayment suggesting that bank failure can be contagious in times of distress

country image and consumer based brand equity relationships and implications for international marketing this paper examines the relationships between consumers country level and product level images of a country and the equity they associate with a brand from that country using canonical correlation analysis results from mallintercept surveys conducted in an australian state capital city indicated that the consumer based equity of a brand was significantly associated with both the macro and micro images of the country of origin of the brand the relationship between these two sets of constructs was found to be positive as well as product category specific furthermore each consumer based brand equity dimension contributed differently to the relationship according to the product category while the contribution of both country image dimensions macro and micro was also product category specific results also showed that cars as a product category are more sensitive to country image than televisions these findings have direct and important implications for international marketers

precautionary saving in the small and in the large the theory of precautionary saving is shown to be isomorphic to the arrow pratt theory of risk aversion making possible the application of a large body of knowledge about risk aversion to precautionary saving and more generally to the theory of optimal choice under risk in particular a measure of the strength of the precautionary saving motive analogous to the arrow pratt measure of risk aversion is used to establish a number of new propositions about precautionary saving and to give a new interpretation of the dreze modigliani substitution effect copyright 1990 by the econometric society

new brand positioning and pricing in an oligopolistic market the positioning and pricing of a new brand requires knowledge about the relationship of both demand and cost with potential attribute locations and prices this paper addresses this problem and illustrates it in the context of the automobile market multi attribute expected utility theory which allows for consumer uncertainty about the brands is used to model individuals behavior attribute weights are estimated from market survey data on brands attributes and preferences using linmap as an estimation procedure expected utility is then updated using the multinomial logit model and choice data to account for the observation that stated preferences do not perfectly reflect the eventual choice it is hypothesized that when faced with an actual choice price may become more important to the consumer while other attributes may become more or less important than is reflected in stated preferences the resulting estimated choice probabilities are aggregated to form demand functions facing each brand which depend on all brands prices and attribute space locations assuming there is a price equilibrium in the existing market and that firms have the same variable cost function variable costs as a function of a brand s attribute levels are estimated given the demand and cost functions facing each firm including the potential new entrant the profit maximizing positioning and pricing of a new brand is analyzed using a game theoretic approach a solution is sought under the assumption that incumbents react to entry by changing their prices possible approaches to the translation of the perceptual attribute positioning of the new brand to physical and engineering attributes are reviewed improvements and future extensions of the study are discussed
