how do consumers make choices a survey of evidence in this paper we review the evidence about the purchase behaviour of consumers we concentrate on the characteristics of the choice process choice of the external information source and nature of the information obtained from these sources the impact of important systematic differences among consumers and products on choice behaviour is also discussed

replicating ricardian equivalence tests with simulated series this paper replicates standard consumption function tests of ricardian equivalence using series generated from a model which nests ricardian equivalence within a non ricardian alternative due to finite horizons and or distortionary taxation the author shows that the estimates of the effects of taxation on consumption are not robust and that standard tests may have weaknesses which can lead to conflicting results whether ricardian equivalence holds or not the simulations also show that no clear conclusions about ricardian equivalence can be drawn from observing a low correlation between the current account and government budget deficits copyright 1997 by american economic association

finite lifetimes and the effects of budget deficits on national saving abstract even though realistic deficit policies shift sizable tax burdens to future generations the assumption of an infinite horizon is a good approximation for analyzing a deficit s short run saving effect on individuals who are neither liquidity constrained nor myopic recent u s experience casts significant doubt on these assumptions however and appears difficult to reconcile with the ricardian equivalence proposition that the timing of taxes does not affect national saving recent deficits have coincided with reduced national saving and a substantial increase in the share of gnp devoted to consumption

the optimum quantity of debt abstract we find that the welfare gains to being at the optimum quantity of debt rather than the current us level are small and therefore concerns regarding the high level of debt in the us economy may be misplaced this finding is based on a model of a large number of infinitely lived households whose saving behavior is influenced by precautionary saving motives and borrowing constraints this model incorporates a different role for government debt than is found in standard models and it captures different cost benefit trade offs on the benefit side government debt enhances the liquidity of households by providing an additional means of smoothing consumption and by effectively loosening borrowing constraints on the cost side the implied taxes have adverse wealth distribution and incentive effects in addition government debt crowds out capital via higher interest rates and lowers per capita consumption

uncertainty and the neutrality of government financing policy abstract some ideas from the theory of finance are applied to consider whether debt financed tax cuts affect desired consumption it is shown that government financing policy is a matter of indifference to infinitely lived households if a perfect substitute for public debt exists the analysis allows for uncertainty about future taxes and for missing markets in some kinds of assets income redistribution risk and the public insurance aspects of an income tax scheme qualify this neutrality result but in general the net effect is ambiguous the real resource costs of financial transacting as well as government superiority in the intermediation process may be one rationale for activist debt management policy a better understanding of functioning capital markets is essential to evaluate these arguments

deconstructing the pioneer s advantage examining vintage effects and consumer valuations of quality and variety several studies have demonstrated an order of entry effect on market share suggesting that pioneers outperform later entrants however other research has pointed out the limitations of these studies and found evidence that many pioneers fail or have low market share given this background the purpose of this research is to understand the conditions under which pioneers are more likely and also less likely to have an advantage we propose a game theoretic model that includes important sources of pioneer advantages as well as disadvantages specifically we incorporate a pioneer advantage due to preemption in markets with heterogeneous tastes in addition we incorporate a potential pioneer disadvantage due to technology vintage effects where later entrants utilizing improved technology can have lower costs and higher quality the model allows us to evaluate the extent of vintage effects necessary to overcome a pioneer s advantage key relationships are found between the magnitude of the pioneer advantage or disadvantage and consumer valuations of product attributes e g variety and quality we empirically validate the model with vintage effect data in 36 product categories and measures of consumer valuations of product variety and quality for 12 of these 36 categories the results show that pioneers do better in product categories wherevariety is more important and worse in categories where productquality is more important pioneers in categories with high vintage effects are shown to have lower market shares and higher failure rates similar results appear when analyzing persistence of market leadership over time further validating our model s major implications we also present two case studies that illustrate key elements of the model

the nonequivalence between deficits and distortionary taxation abstract this paper examines how relaxing the assumption of lump sum taxation affects the ricardian equivalence theorem in a model with income taxation instead of lump sum taxation structural deficit finance causes keynesian like effects even though government bonds are not perceived as net wealth a temporary substitution of debt for taxation significantly increases consumption work and output initially the same effects as in the keynesian case where the implied future tax liability is not perceived but in contrast to the keynesian case investment also increases initially in the long run however deficit finance significantly reduces investment work output and consumption

the reaction of household consumption to predictable changes in social security taxes the key implication of rational expectations and the basic life cycle permanent income hypothesis that predictable changes in income have no effect on the growth rate of consumption expenditures is examined this implication is important for understanding the effectiveness and optimal timing of fiscal policy the causes and propagation of business cycles and the effects of income fluctuations on the growth rate of the economy using household level consumption data from the consumer expenditure survey whether expenditures on nondurable goods increase contemporaneously with predictable changes in social security tax withholding is tested it is found that households do change their consumption expenditures in response to the predictable fluctuations in income induced by the social security tax system

who is credit constrained in the u s economy an important assumption of the life cycle model of consumption is the postulate of perfect capital markets this hypothesis has recently been challenged by substantial empirical evidence hall and mishkin 1982 using the panel study of income dynamics estimate that 20 percent of united states families are liquidity constrained mariger 1986 derives a life cycle model with endogenous liquidity constraints and using a cross section estimates this fraction to be 19 4 percent hubbard and judd 1986 simulate a model with a constraint on net worth which shows that with reasonable assumptions about preferences 19 0 percent of united states consumers are liquidity constrained the emerging consensus points therefore to a fraction of approximately 20 percent of the population behaving in a manner that is inconsistent with the pure life cycle model in addition hayashi 1985 and zeldes 1989 investigate the correlation among consumption wealth and income for various population groups and infer that liquidity constraints are more important for younger families with low levels of wealth and saving the main limitation of these studies is that in their data sets constrained consumers are not observable and have to be identified via indirect evidence thus there is as yet little firm evidence about the characteristics of the consumers who are likely to be credit constrained this paper adopts an approach that differs from previous tests for liquidity constraints because it makes use of data where constrained consumers are observable and explicitly links their existence to credit market imperfections and personal characteristics the data drawn from the 1983 survey of consumer finances scf and described in section ii provide information on individuals whose request for credit has been rejected by financial intermediaries in section iii a model is developed in which consumers and lenders behavior jointly determines the probability that a consumer is rationed in the credit market this probability is then

adding asymmetrically dominated alternatives violations of regularity and the similarity hypothesis an asymmetrically dominated alternative is dominated by one item in the set but not by another adding such an alternative to a choice set can increase the probability of choosing the item that dominates it this result points to the inadequacy of many current choice models and suggests product line strategies that might not otherwise be intuitively plausible

the effect of liquidity constraints on consumption a cross sectional analysis this paper examines the effect of liquidity constraints on consumption expenditures using a single year cross section data set a reduced form equation for consumption is estimated on high saving households by the tobit procedure to account for the selectivity bias since high saving households are not likely to be liquidity constrained the estimated equation is an appropriate description of how desired consumption that would be forthcoming without liquidity constraints is related to the variables available in the cross section data when the reduced form equation is used to predict desired consumption the gap between desired consumption and measured consumption is most evident for young households

are consumers forward looking evidence from fiscal experiments how changes in current and future income affect consumer spending is a perennial question in macroeconomics and public finance theoretical constructs such as the permanent income hypothesis are of limited assistance in resolving this issue because they neglect borrowing constraints and other market imperfections that can significantly affect the marginal propensity to spend out of current income recent empirical work has also proven inconclusive since whether consumption responds to income fluctuations by more or less than the permanent income hypothesis predicts turns critically upon whether disposable income follows a random walk or is stationary around a longrun trend see john campbell and angus deaton 1987 this controversy is unlikely to be resolved conclusively because it is notoriously difficult to distinguish a stationary but highly persistent time series from one that is nonstationary these difficulties suggest the importance of searching for natural experiments income shocks with predictable and well understood effects on future income to test models of consumer behavior changes in federal tax and transfer policy during the last two decades provide several episodes of this type analyzing the effects of these tax changes is also central to understanding the role of fiscal policy in affecting national saving this paper examines two aspects of consumer response to tax changes section i argues that consumption responds to temporary income tax shocks by more than the permanent income hypothesis would suggest results from the 1975 tax rebate in particular suggest that a 1 increase in transitory income raises spending by about 20 cents section ii examines consumption responses to tax announcements although the results are not conclusive they suggest that some consumers do not adjust consumption in anticipation of tax changes the final section sketches some implications for analyzing fiscal policy

ricardian equivalence with wage rate uncertainty this paper examines ricardian equivalence when the wage rate is uncertain and people choose their labor supply the author reviews the model of robert b barsky gregory mankiw and stephen p zeldes 1986 and shows that their finding of a positive marginal propensity to consume out of a tax cut is due to the insurance aspect of distortionary taxation then the author explores the trade off between this insurance aspect and labor supply distortions in the context of a model similar to that of barsky mankiw and zeldes but incorporating labor supply copyright 1996 by ohio state university press

overcoming the early entrant advantage the role of alignable and nonalignable differences prior research has focused on early entrant advantage rather than on theories that explain and predict how late entrants can surpass the early entrant s performance in this research the authors p

the macroeconomic effects of distortionary taxation abstract prescott 1986 estimates that technology shocks account for 75 of the fluctuations in the postwar u s economy this paper reestimates the contribution of technological change for a standard business cycle model that includes a public sector and fiscal disturbances i find that a significant fraction of the variance of aggregate consumption investment output capital stock and hours of work can be explained by disturbances in labor and capital tax rates and government consumption i also use the model to quantify the welfare costs of capital and labor taxation for both the time series and welfare calculations maximum likelihood estimates of taste technology and policy parameters are used

decision ambiguity and incumbent brand advantage this article examines the role of decision ambiguity in judgments that consumers make about an incumbent the brand a consumer currently uses versus an attack brand a new superior competitor it is hypothesized that decision ambiguity creates an advantage for the incumbent a conceptualization of decision ambiguity is offered in three experiments factors that can cause decision ambiguity are manipulated and their effects on preference for the incumbent are investigated the results underscore the role of decision ambiguity in incumbent brand advantage in two other experiments boundary conditions are examined t his research focuses on the advantages of incumbency the term incumbent refers to the brand that a consumer first chooses in a product category a brand may achieve incumbent status by being the first brand chosen by consumers entering a mature product class or by being a pioneer in a new product class an incumbency advantage occurs when consumers prefer the incumbent to an objectively superior but later encountered competitor referred to as the attack brand the objectives of this research are to examine conditions under which an incumbent advantage obtains and to conduct an exploratory investigation of the psychological processes that underlie it research in marketing has not been specific about either the processes or the conditions that result in an incumbency advantage although research on the related topic of brand loyalty has emphasized the role of emotional commitment or ego involvement in repeat purchase behavior e g jacoby 197 1 jacoby and chestnut 1978 other psychological processes are surely operative on the basis of behavioral decision theory research i propose a framework that offers a different explanation for consumer repeat purchase behavior in addition this framework offers an explanation of the pioneering advantage that is consistent with but independent of prior research e g carpenter and nakamoto 1989 kardes and kalyanaram 1992 schmalensee 1982 with a few notable exceptions in the domain of the pioneering advantage carpenter and nakamoto 1989 kardes and kalyanaram 1992 kardes et al 1993 research in marketing has not provided a psychological account of the incumbency advantage however behavioral decision theory research offers some suggestions for example samuelson and zeckhauser 1988 showed that people prefer a previously chosen option over others this pervasive tendency labeled the status quo bias has been demonstrated across a range of decisions samuelson and zeckhauser 1988 invoked a variety of psychological mechanisms to explain the phenomenon including commitment induced by sunk costs regret avoidance cognitive misperception and feeling of control however samuelson and zeckhauser 1988 were silent with respect to conditions that would make such biases present absent or even reversed cf biehal and chakravarti 1983 the present research identifies the decision characteristics that can increase or decrease the likelihood of the status quo bias the central premise of this research is that the incumbency advantage will vary as a function of the level of ambiguity in the decision environment

social security benefits consumption expenditure and the life cycle hypothesis this paper examines the impact of changes in social security benefits on aggregate consumption expenditure under the null hypothesis there should be no contemporaneous effect at the monthly frequency because increases in benefits have always been announced at least 6 weeks prior to payment the paper develops overwhelming evidence contrary to the null that benefits have affected aggregate spending the results have strong implications for several important issues including ricardian equivalence government policy irrelevance and the excess sensitivity of consumption to changes in income

fiscal policy with heterogeneous agents and incomplete markets i undertake a quantitative investigation into the short run effects of changes in the timing of proportional income taxes for model economies in which heterogeneous households face a borrowing constraint temporary tax changes are found to have large real effects in the benchmark model a temporary tax cut increases aggregate consumption on impact by around 29 cents for every dollar of tax revenue lost comparing the benchmark incomplete markets model to a complete markets economy income tax cuts provide a larger boost to consumption and a smaller investment stimulus when asset markets are incomplete copyright 2005 wiley blackwell

exploring the income distribution business cycle dynamics abstract we document the business cycle behavior of the us income distribution and explore the extent to which unemployment spells and cyclically moving factor shares account for this behavior by analyzing four heterogeneous household extensions of the neoclassical growth model we conclude i that partitioning the population into five types subject to type specific employment processes seems to be enough to account for most aspects of the us income distribution business cycle dynamics ii that the role played by cyclically moving factor shares is small and iii that the income distribution business cycle dynamics may be essentially independent from the significant part of the observed wealth concentration that these model worlds fail to account for

the response of household consumption to income tax refunds a central implication of the life cycle or permanent income theory is that consumption should not respond to predictable fluctuations in income tests of this implication have yielded mixed results especially on micro data angus deaton 1992 martin browning and annamaria lusardi 1996 in large part this might be due to the difficulties of isolating the predictable component of income at the micro level most tests proceed by instrumenting for income but since the available instruments are typically poor such tests might be prejudiced against finding significant excess sensitivity of consumption to income john shea 1995 also it is not clear how closely the resulting econometric predictions of income coincide with agents actual expectations of income to avoid these difficulties this paper examines the response of household consumption to a particular type of income that is both predictable and transitory income tax refunds since a refund depends on events in the previous calendar year it is predictable income as regards consumption in the year of its receipt consequently under the life cycle theory consumption should not increase on receipt of a refund 2 in addition to testing the canonical model of consumption this paper provides estimates interpretable as the marginal propensity to consume mpc out of refunds since federal tax refunds now amount to over 80 billion per year averaging well over 1 000 per refund these estimates are of interest in themselves more generally they bear on the impact of even preannounced and temporary changes in fiscal policy the paper begins by surveying related studies in section i section ii describes the data the consumer expenditure survey cex which of the leading u s micro data sets has the most comprehensive coverage of expenditure the empirical specification is set out in section hi section iv reports the results and section v concludes

brand retrieval consideration set composition consumer choice and the pioneering advantage recent research on the pioneering advantage has shown that consumers often prefer pioneering brands to follower brands recent research on consumer choice suggests that information about brands is filtered through a series of sequential cognitive processes this study attempts to integrate these two separate lines of research by investigating the effects of pioneering on each stage of the multistage decision process a within subjects longitudinal experiment was conducted to simulate brand order of entry into a new market we also developed a sequential logit model to isolate the direct impact of pioneering on each stage of the decision process while controlling for indirect effects of pioneering on previous stages the results revealed that the pioneering brand vs followers is more likely to be retrieved considered and selected moreover the results revealed that consumers are more likely to bypass consideration set formation when the choice decision is simple vs complex theoretical and practical implications of the results are discussed

perceived inflation persistence this article constructs and estimates a measure called perceived inflation persistence that can be used to determine if professional forecasters inflation forecasts indicate there has been a change in inflation persistence this measure is built via the implied autocorrelation function that follows from the estimates obtained using a forecaster specific state space model findings indicate that u s perceived inflation persistence has changed since the mid 1990s with more consensus among forecasters at lower levels of persistence when compared to the autocorrelation function for actual inflation forecasters typically react less to shocks to inflation than the actual inflation data would suggest

the effect of borrowing constraints on consumer liabilities this paper explores the effects of liquidity constraints on consumer liabilities while much empirical evidence attests to the importance of liquidity constraints in the u s economy evidence about the effects of borrowing constraints on consumer balance sheets is scarce using the 1983 survey of consumer finances data we estimate desired borrowing for unconstrained households we then evaluate the gap between predicted and observed debt for the sample of liquidity constrained consumers predicted debt is 75 percent higher than actual debt in the liquidity constrained sample thus the effect of removing borrowing constraints has quantitatively important implications for the allocation of debt in the household portfolio the removal of borrowing constraints would raise aggregate household liabilities by 9 percent copyright 1993 by ohio state university press
