the measurement and trend of inequality comment in a recent article in this review morton paglin proposes a measure of concentration which he claims will correct the gini ratio for overstatement in populations where each individual may be expected to vary his income or wealth over his life cycle the paglin measure suggests that the gini ratio overstates income concentration in the united states by a third and does not reveal a 23 percent decline in concentration which has occurred between 1947 and 1972 these results are based on an improper decomposition of the gini ratio in this note i decompose the gini ratio to derive the paglin measure it is shown to correct for neither demographic nor life cycle income effects and to understate intracohort income or wealth inequality if properly normalized the paglin measure shows that the gini overstates u s income concentration by 7 percent or less and indicates a decline in u s interfamily income concentration of less than 12 percent four percentage points of this decline are the result of demographic change while less than 7 points comparable to the 5 percent decline of the gini are the result of decreased income concentration within cohorts of family heads decomposition further reveals major changes in the division of income among cohorts and in concentration of income within cohorts these changes compensate each other in the paglin measure the use of which as a measure of income or wealth concentration is not recommended the gini concentration ratio

assessing demand artifacts in consumer research an alternative perspective in a recent insightful article on demand artifacts in consumer research t a shimp e m hyatt and d j snyder using a 1989 article by j j kellaris and a d cox as backdrop provided an appraisal of demand artifacts in this article we critically evaluate some of the assumptions and conclusions of shimp et al s analysis of the extent to which demand artifacts might explain the 1982 results of g j gorn as analyzed by kellaris and cox in addition we offer some useful suggestions for minimizing demand problems

evaluating welfare reform in the united states this paper reviews the economic literature on welfare reform over the 1990s a brief summary of the policy changes is followed by a discussion of the methodological techniques that analyze the effects of these changes on outcomes the paper then critically reviews the econometric and experimental literature on caseload changes labor force changes poverty and income changes and family formation changes a growing body of evidence suggests that recent policy changes have influenced economic behavior and well being one particular set of new style welfare programs seems to show especially promising results with significantly increased work and earnings and reduced poverty

labour supply effects of unemployment insurance benefits data from the 1976 wave of the panel study of income dynamics are employed to study the effect of unemployment insurance ui benefits on weeks worked ols regressions to model labour supply behaviour are estimated for both recipients and nonrecipients of ui benefits we find some inteesting differences between the labour supply behaviour of ui recipients and nonrecipients

us federal redistributive income policies the purpose of this paper is to present a statiscial model of inequality that allows us to analyse simultaneously the impact of several major redistributive expenditure policies as well as analysing the impact of income taxation on inequality the paper includes multivariate exogeeity tests to determine whether the policies have caused the observed income distribution or if there is feedback i e inequality in the distribution has lead to enhanced or diminished redistributive policies the direction of causality for these policies has not to ourr knowledge been previously examined this paper examines the usual redistributive vehicles of transfer payments social security medicare and medicaid as well as analysing the impact of the personal income tax system on inequality using time series analysis we can allow for lagged effects of these policies as well as current period effects this lagged effects specification may be sugggestive of behavioural responses to policy changes

means testing versus universal provision in poverty alleviation programs this paper contrasts the use of means tested and universal schemes in the alleviation of poverty using a class of poverty measures the authors illustrate the trade off from the fact that means testing is costly to both the government and the claimant while universal provision entails a leakage to the nonpoor the paper provides numerical as well as analytical results copyright 1990 by the london school of economics and political science

leader driven primacy using attribute order to affect consumer choice leader driven primacy uses initial product information to install a targeted brand as the early leader in a choice between two brands biased evaluation of subsequent attributes builds support for the targeted brand causing the choice itself to be biased study 1 finds evidence of this effect in choices between two equally attractive brands study 2 extends the finding to a situation where one brand is inferior and to conditions where participants do not explicitly identify their leader study 3 shows how leader driven primacy can be reduced by encouraging brand based processing

family welfare cultures strong intergenerational correlations in various types of welfare use have fuelled a long standing debate over whether welfare receipt in one generation causes welfare participation in the next generation some claim a causal relationship in welfare receipt across generations has created a culture in which welfare use reinforces itself through the family others argue the determinants of poverty or poor health are correlated across generations so that children s welfare participation is associated with but not caused by parental welfare receipt however there is little empirical evidence to sort out these claims in this paper we investigate the existence and importance of family welfare cultures in the context of norway s disability insurance di system to overcome the challenge of correlated unobservables across generations we take advantage of random assignment of judges to di applicants whose cases are initially denied some appeal judges are systematically more lenient which leads to random variation in the probability a parent will be allowed di using this exogenous variation we find strong evidence that welfare receipt in one generation causes welfare participation in the next generation when a parent is allowed di their adult child s participation over the next five years increases by 6 percentage points this effect grows over time rising to 12 percentage points after ten years while these findings are specific to our setting they serve to highlight that welfare reforms can have long lasting effects on program participation since any original effect on the current generation could be reinforced by changing the participation behavior of their children as well the detailed nature of our data allows us to compare the intergenerational transmission with spillover effects in other networks and to explore mechanisms our findings point to a special link between parents and their children with little impact due to close neighbors di participation we find suggestive evidence that what may change as a result of a parent being allowed di is their children s beliefs about the efficacy of trying to get on to the di program or their attitudes about di participation and its stigma

a critique of darley and lim s alternative perspective this reply challenges w k darley and j s lim s conclusions that an earlier article of ours misleads consumer researchers about the role and treatment of demand artifacts and that our analysis regarding g j gorn s experiments are flawed we also question darley and lim s proposals for minimizing demand artifacts

goal reversion in consumer choice how do consumers manage goal conflicts before making a choice this question was studied by examining emerging preferences in choices involving two products that were means to conflicting goals these preference patterns revealed that an initially active goal which had been set aside to reconcile a goal conflict exerted greater than expected influence on the remainder of the choice process this influence was manifest in a tendency for consumers to revert to the product aligned with the initially active goal upon seeing information that objectively favored neither product the prevalence of the reversion i e flip flop preference pattern suggests that activation of a set aside goal escalates when it is set aside much as if its pursuit had been impeded by an external force in addition to revealing goal reversion in a variety of choice contexts the studies in this article also find that goal reversion is moderated by goal conflict

what to say when influencing consumer choice by delaying the presentation of favorable information delaying the presentation of some favorable information about an alternative e g a product service brand store or cause until after consumers have completed their pre choice screening can increase that alternative s choice share while such a delay reduces the alternative s chance of surviving the screening it can actually increase its probability of ultimately being chosen evidence from five experiments demonstrates this preference enhancing effect of the delayed presentation of favorable information and it illustrates the underlying preference dynamics across decision stages associated with such a delay the findings also indicate that this preference enhancing effect is driven by a combination of two mental mechanisms a shift in the decision weights of attribute dimensions rendering dimensions on which a delay occurs more influential across all alternatives and an overall preference boost for the alternative about which information is delayed

are sale signs less effective when more products have them we analyze data from a variety of sources including historical data from a women s clothing catalog a field study in that catalog survey responses to catalog stimuli and grocery store data for frozen juice toothpaste and tuna the analysis yields three conclusions first sale signs are less effective at increasing demand when more items have them second total category sales are maximized when some but not all products have sale signs third placing a sale sign on a product reduces the perceived likelihood that the product will be available at a lower price in the future but the effect is smaller when more products have sale signs by ruling out alternative hypotheses the findings suggest that moderation of the sale sign effect is in part due to reduced credibility when they are used on more products the credibility argument is motivated in part by a recent paper that presented an equilibrium model predicting that customers who lack knowledge of market prices rely on point of purchase sale signs to help evaluate posted prices anderson and simester 1998 the model predicts that sale signs increase demand but that the increase is smaller when more products have them this moderating effect regulates how many sale signs stores use and makes customer reliance on these cues an equilibrium strategy to evaluate whether the number of sale signs moderates their effectiveness we compare demand for items with sale signs when varying the number of sale signs on other products for this comparison we use two datasets describing demand for products in a women s clothing catalog the first dataset describes customer orders for the same set of items across three sequential issues of the catalog the second dataset is a field test conducted by mailing different versions of the catalog to randomly selected customer samples reassuringly although the datasets do not share the same limitations the findings are consistent and indicate that sale signs are less effective when more products have them in addition to the credibility explanation there are at least two alternative explanations for this result first using a sale sign to make a product more attractive may lead to substitution of demand from other sale items within a store and so demand may vary even if there is no change in the credibility of the sale signs to discriminate between the substitution and credibility explanations we evaluate whether total category demand is maximized when some but not all products in the category have sale signs the credibility explanation implies that adding another sale sign will eventually decrease total category sales when many items already have sale signs in contrast if adding a sale sign to an item leads solely to substitution from other products within or outside the category we will not observe a decrease in total category demand we test the total category sales prediction using grocery store scan data describing total category demand for frozen juice toothpaste and canned tuna the findings reveal that in all three categories there is a significant reduction in aggregate demand a second alternative explanation is that sale signs focus customer attention on products with these cues distinguishing between the attention and credibility explanations is a difficult task they both imply that sale signs deliver less information when there are too many sale signs the credibility argument predicts that this occurs because the signs are noticed but not believed the attention explanation predicts that the signs are less likely to be noticed when attention is diluted by a large number of sale signs to discriminate between the credibility explanation and this attention effect we use survey measures to evaluate a third hypothesis this hypothesis predicts both that placing a sale sign on a product reduces the perceived likelihood that the product will be available at a lower price in the next period and that this effect is smaller when more items have them in an attempt to control for the attention effect we focus subjects attention on a set of focal items under these conditions it is unlikely that subjects overlook sale signs on these items more important the likelihood of overlooking sale signs on the focal items is unlikely to depend on how many other items also have sale signs the results confirm both that the presence of a sale sign reduced subjects expectations that an item would be available at a lower price in the future and that this effect is smaller when more items have sale signs

precautionary savings a panel study theoretical literature shows that income uncertainty boosts saving yet empirical work is incomplete i test for the precautionary motive for saving using panel data knowing this motive s size is important for gauging the responsiveness of saving to government programs that reduce uncertainty and for comparison to other motives such as bequests most empirical studies of precautionary saving use either aggregate time series or cross sectional data which cannot capture the effects of individual income uncertainty i derive measures of total permanent and transitory income uncertainty from panel data the national longitudinal survey and find a strong precautionary motive a doubling of uncertainty increases the ratio of wealth to permanent income by 29

inherent rule variability in consumer choice changing rules for change s sake the present research demonstrates that consumers tend to vary their use of decision rules independent of option and set characteristics in five experiments increased choice of a particular option e g lower price brand name or compromise option was associated with relatively decreased choice of that same generic option on occasions that followed results indicate that this inherent rule variability is not an effect of background contrast but instead relates to consumers favorable valuation of decision change itself this research implies that the idea of contingent decision making applies not only to decision outcomes but also to decision processes

consumer learning in a turbulent market environment modeling consumer choice dynamics after a product harm crisis abstract the authors empirically study consumer choice behavior in the wake of a product harm crisis which creates consumer uncertainty about product quality they develop a model that explicitly incorporates the impact of such uncertainty on consumer behavior assuming that consumers are uncertain about the mean product quality level and learn about product quality through the signals contained in use experience and the product harm crisis and also that consumers are uncertain about the precision of the signals in conveying product quality and update their perception of this precision over time they estimate this model using a scanner panel data set that includes consumer purchase history before during and after a product harm crisis that affected kraft foods australia s peanut butter division in june 1996 the proposed model fits the data better than the standard consumer learning model which assumes consumers are uncertain about product quality level but the precision of information in conveying p

negotiation of profit sharing contracts in industry we examine the properties of profit sharing in a game theoretic oligopoly model of industry profit sharing contracts are viewed as a means of strategic commitment not as an internal incentive system in our model firms choose a contract subject to the employees participation constraint in a first stage and compete on the output market in a second stage we show that the choice of a profit sharing contract by each firm is a non cooperative equilibrium in the case of cournot competition the game under study has the structure of the prisoners dilemma the case of price competition on the output market leads to somewhat different conclusions

a measure of horizontal inequity politicians academicians and the general public alike have perceived that the status quo tax and transfer legislation creates inequities among living units tax laws create numerous situations in which living units with seemingly equal abilities to pay are taxed quite different amounts state by state differences in welfare eligibility rules benefit schedules and administrative procedures the general unavailability of cash welfare to childless nonaged healthy couples and single individuals and other features of transfer programs similarly provide vastly different levels of income support to units with equal needs advocates of major tax and welfare reform have marshalled such evidence into a central argument in favor of their proposals while there is wide agreement that the process of redistributing incomes abounds with inequities there have been few attempts to quantify their extent 2 this paper develops a measure of horizontal inequity and illustrates its use section ii discusses the concept of horizontal equity then builds upon familiar lorenz curve gini coefficient analysis to derive the inequity index the third part considers some problems of implementing the measure and illustrates it section iv provides a short conclusion

measuring the influence of unemployment insurance on unemployment experiences this article investigates the comprehensive effects of unemployment insurance ui policies on the amount of time and unemployment that individuals report between jobs the econometric model jointly determines the effects of ui on the lengths of nonemployment spells the classification of these spells as unemployment and the likelihood of collecting program benefits the model carefully attempts to isolate variation in ui benefits attributable to differences in generosity across programs to avoid biases in estimating policy effects induced by other contaminating sources of benefit variation using data on men from the national longitudinal survey of youth the empirical results find a ui recipients typically experience longer spells between jobs at least up to the exhaustion of ui benefits and report substantially larger fractions of these spells as unemployment b weekly benefit amounts exert no significant influence on the likelihood of ui recipiency on the length of spells between jobs or on t

loss aversion and labor supply in many occupations workers labor supply choices are constrained by institutional rules regulating labor time and effort provision this renders explicit tests of the neoclassical theory of labor supply difficult here we present evidence from studies examining labor supply responses in neoclassical environments in which workers are free to choose when and how much to work despite the favorable environment the results cast doubt on the neoclassical model they are however consistent with a model of reference dependent preferences exhibiting loss aversion and diminishing sensitivity jel j22 b49

cash welfare as a consumption smoothing mechanism for divorced mothers abstract while there has been considerable research on the disincentive effects of cash welfare under the aid to families with dependent children afdc program there is little evidence on the benefits of the program for single mothers and their children one potential benefit of this program is that it provides short run consumption insurance for women at the point that they become single mothers this is only true however to the extent that the program is not crowding out other sources of support such as own savings labor supply or transfers from others i assess the importance of this insurance mechanism by measuring the extent to which afdc smooths the consumption of women who transition to single motherhood through marital dissolution i use longitudinal data on family structure and consumption expenditures on food and housing from the panel study of income dynamics psid matched to information on the welfare benefits available in each state and year over the 1968 1985 period i find that raising potential benefits by one dollar raises the food and housing consumption of women who get divorced and their families by 28 cents this estimate implies that for each dollar of afdc received by this population their consumption of these categories of goods rises by up to 51 cents this is roughly the share of food and housing in the consumption bundle of divorced mothers and their families suggesting little crowdout of other sources of support

labor supply response to welfare programs a dynamic analysis previous static analyses of the work disincentive effects of welfare programs are extended to a dynamic context using a sample of continuous longitudinal labor market histories estimates are derived for welfare nonwelfare differences in labor market flows among the states of employment unemployment and nonparticipation the estimates are used to identify the main sources of the lower employment and labor force participation rates and higher unemployment rate of welfare recipients the findings indicate that welfare programs have substantial effects on virtually every labor market transition examined but that the primary source of the static work disincentive effect is slower entry into employment

using differences in knowledge across neighborhoods to uncover the impacts of the eitc on earnings we develop a new method of estimating the impacts of tax policies that uses areas with little knowledge about the policy s marginal incentives as counterfactuals for behavior in the absence of the policy we apply this method to characterize the impacts of the earned income tax credit eitc on earnings using administrative tax records covering all eitc eligible lers from 19962009 we begin by developing a proxy for local knowledge about the eitc schedule the degree of sharp bunching at the exact income level that maximizes eitc refunds by individuals who report self employment income the degree of self employed sharp bunching varies signi cantly

pension wealth and household savings tests of robustness abstract a substantial literature exists on the impact of pension schemes both public and private on the level of household saving yet there is no clear consensus on the impact of pensions on private saving in this paper we show how beliefs about this displacement effect are modified by prior beliefs both about variables which might be relevant in an equation for private savings and about the magnitude of the displacement effect using data for 8279 canadian households and estimates of pension wealth both private and social security which we construct for each household in the sample the estimated displacement effects are found to be relatively robust with respect to both types of prior belief

price as a stimulus to think the case for willful overpricing consumers aware of a new benefit will often experience uncertainty about its personal relevance or usage value this paper shows that the decision to deliberate further to resolve this uncertainty and reach a polarized judgment of personal relevance critically depends on the posted price in particular a price above the consumer s initial willingness to pay might be thought provoking and enhance the perception of relevance with a certain probability this behavioral mechanism is introduced formally and by way of an experiment with reference to the purchase of organic lettuce and fair trade coffee accounting for the effect of price as a stimulus to think a monopolistic firm should either over price transgressive pricing or under price regressive pricing in comparison to the consumer s willingness to pay under certain circumstances the firm should also empower consumers with means that reduce the effort of deliberation

in kind transfers cash grants and the supply of labour abstract this paper corrects the notion that somehow benefits given in kind interfere less with the work leisure choice than cash grants of equivalent monetary value in a simple model the analysis proves that the true effect depends on the extent of the in kind transfer and the substitutability of the good in question with leisure

unrealistically optimistic consumers a selective hypothesis testing account for optimism in predictions of future behavior we propose that when predicting future behavior consumers selectively but unwittingly test the hypothesis that they will behave ideally this selective hypothesis testing perspective on unrealistic optimism suggests that estimates of future behavior should be similar to those made by individuals who assume that conditions will be ideal moreover consumers who initially provide estimates assuming that conditions will be ideal should recognize that the world is not ideal and so should test a more realistic hypothesis in line with these predictions we find that ideal world estimates e g in an ideal world how often will you exercise next week do not differ from standard estimates e g how often will you exercise next week we also find that individuals who initially estimate their behavior in an ideal world subsequently make more realistic predictions

price search in a product market regressions using panel data on grocery purchases show lower purchase costs are significantly associated with a larger number of stores visited per week there is also evidence but somewhat weaker of diminishing gains from such search an economic model of the determinants of search suggests that prices paid quantities purchased and number of store visits are interrelated a view supported by results of estimating a proposed simultaneous equations model

public transfers family socioeconomic traits and the job search behavior of the unemployed evidence from puerto rico abstract this paper explores the theoretical and empirical associations between the job search efforts of the unemployed and the socioeconomic characteristics of the family it takes as a point of reference that certain supply side phenomena may contribute to puerto rico s high open unemployment rate the statistical analyses carried out indicate that there does exist what can be labeled luxury unemployment in other words government provided transfer payments generate disincentive effects with respect to the job market behavior of the unemployed moreover the dependency status of the individual within the family group also leads to lower job search effort

the effect of price on preference consistency over time construal level theory indicates that consumers tend to prefer products high in desirability greater functionality for distant future decisions but switch their preferences toward products high in feasibility greater usage convenience for near future decisions the current research demonstrates that price information traditionally considered as a feasibility cue can increase consumers near future preference toward products with greater functionality despite their low convenience leading to preference consistency over time as the underlying mechanism price information increases the functionality importance for near future decisions due to consumers enhanced value seeking tendency when seeing price and their lay belief that greater functionality represents higher value further when consumers are led to believe that greater convenience represents higher value price and the value seeking tendency result in a greater preference toward easy to use products for the distant future and lead to preference consistency across time as well theoretical implications are discussed

using notches to uncover optimization frictions and structural elasticities theory and evidence from pakistan we develop a framework for nonparametrically identifying optimization frictions and structural elasticities using notches discontinuities in the choice sets of agents introduced by tax and transfer policies notches create excess bunching on the low tax side and missing mass on the high tax side of a cutoff and they are often associated with a region of strictly dominated choice that would have zero mass in a frictionless world by combining excess bunching observed response attenuated by frictions with missing mass in the dominated region frictions it is possible to uncover the structural elasticity that would govern behavior in the absence of frictions and arguably capture long run behavior we apply our framework to tax notches in pakistan using rich administrative data while observed bunching is large and sharp optimization frictions are also very large as the majority of taxpayers in dominated ranges are unresponsive to tax incentives the combination of large observed bunching and large frictions implies that the frictionless behavioral response to notches is extremely large but the underlying structural elasticity driving this response is nevertheless modest this highlights the inefficiency of notches by creating extremely strong price distortions they induce large behavioral responses even when structural elasticities are small

replacement income duration of unemployment and the migration of unemployed prime age males the relationship between the interstate migration of unemployed males of prime working age i e 25 44 years of age the level of unemployment replacement income and the duration of unemployment spells is addressed through the use of a relatively untapped data source the us census s survey of income and program participation sipp the rich set of details that are provided in this database allows a more precise empirical analysis of the above relationships than has been possible with psid cps and other previously used databases by restricting the sample to a relatively homogeneous segment of the work force its is possible to isolate better the effects of unemployment replacement income and job search duration on the migration decision of unemployed workers without the confounding effects of the variety of demographic factors that previous studies have shown to influence labour force migration the results suggest that for unemployed prime working age males the probability of migration is negativel

the economic implications of disability insurance in canada the article empirically estimates the effects of disability pensions provided under the canada quebec pension plans on the labor force participation rates of males aged 45 64 years two data sets are used one consists of pooled cross section annual time series data by province for the years 1975 83 the other consists of observations as of 1985 on 651 males in the specified age group naive estimation results from both sets of data suggest a large negative effect of pension income in the case of the micro data this effect becomes small and statistically nonsignificant when more sophisticated estimation methods are used

does the new economy measure up to the great inventions of the past abstract during the four years 1995 99 u s productivity growth experienced a strong revival and achieved growth rates exceeding that of the golden age of 1913 72 accordingly many observers have declared the new economy to be an industrial revolution even more important than the second industrial revolution of 1860 1900 which made the golden age of productivity growth possible this paper dissects the recent productivity revival subtracts out a cyclical component and concludes that there is no revival of the productivity growth trend in the 88 percent of the private economy lying outside of the durables manufacturing sector the paper explains this surprising finding by pointing to limitations in computers and the internet in comparison with the great inventions of the past

tourist destination and experience choice a choice experimental analysis of decision sequence effects abstract while many studies have investigated travel motives and modelled holiday destination choices none have directly modelled choice of type of holiday experience and how these two choices interrelate this study tests whether early exposure to geographical destination or experience type information in a decision task influences consumers final choices when choosing a holiday the study compares two choice tasks that have the same instructions and attributes but differ with respect to which attribute is exposed first and is used to label the choice options the destination name or the experience type findings show that early exposure to either attribute enhances the importance of the attribute although the effect is less pronounced for experiences than for destinations the findings are explained using the psychological notions of leader primacy complacency and induced mindset the research conducted in australia shows that sequential effects can be very important in shaping tourism consumption choices and decision making

should social security benefits be means tested social security retirement benefits distort the saving decisions of workers who are rational enough to save for their future since the implicit rate of return in an unfunded social security program is less than the marginal product of capital the resulting decline in saving causes a welfare loss the present paper examines the conditions under which the welfare loss could be reduced by replacing the current universal social security program with a means tested program that pays benefits only to those individuals with little or no other retirement income or assets every society must solve the problem of supporting those individuals who become too old to work but have not made adequate provision for their own old age by saving when they were young at the present time the major industrial countries of the world have responded to this problem by creating social security programs that tax the working population and use the proceeds to provide a universal benefit to all retirees regardless of their financial condition this universal provision of social security benefits distorts the saving decisions of those workers who are rational enough to plan for the future since the implicit rate of return that taxpayers get on their this research is part of the nber study of the government budget and the private economy a more complete version of this paper with some numerical calculations is available as nber working paper no 1775 feldstein 1985b i am grateful to gilbert metcalf for assistance with the calculations presented in this paper and for helpful discussions for a discussion of the effect of promised retirement benefits on the savings of employees see feldstein 1974 1982 barro 1974 1978 has discussed an interesting

american federalism welfare policy and residential choices the relationship between welfare benefit levels and the residential choices of the poor raises two issues for federalism in the united states do state benefit levels affect the residential choices of the poor do residential choices of the poor affect the level at which a state sets its benefit levels empirical studies have seldom studied the interconnection between these two issues this research estimates simultaneously the mutual effects of welfare benefits and poverty rates while controlling for other economic and political variables when benefit levels become high the size of the poverty population increases conversely when poverty rates become high benefit levels are cut the findings are consistent with the claim that state determined benefit levels distort policy and residential choices

the influence of generic advertising on brand preferences more than a billion dollars is spent annually on generic advertisements that promote the consumption of commodity goods generic advertising is designed to increase primary demand or the size of the pie without affecting selective demand or the share of the pie we find evidence to the contrary generic advertising increases the consumer s sensitivity to changes in price and systematically alters brand preferences these effects of generic advertising can be attributed to the tendency of generic ads to change the relative importance of the attributes used to evaluate the brands the results have implications for the public policy issue of how to effectively implement generic advertising without differentially benefiting certain brands and the managerial issue of how to integrate generic and brand advertising in order to achieve product category and brand differentiation goals

labour supply impacts of effective welfare programme parameters a reanalysis we quantify the impact of effective welfare programme parameters on the labour supply of single female household heads the primary group of welfare recipients in the usa our panel of data is derived from the us census bureau s current population survey for the years 1979 to 1990 inclusive behavioural impacts from a range of economic variables are consistent in sign with predictions made by economic theory we find that effective welfare gurantee levels and the effective tax rate on earned income both significantly decrease labour supply the marginal effects of these welfare programme parameters are economically small a us 1000 increase in the expected welfare guarantee level reduces annual labour supply by about 36 hours a 10 percentage point increase in the effective tax rate on earned income reduces annual labour supply by about 7 5 hours

the backward hustle an experimental investigation of tax code notches and labor supply abstract the phase in and phase out of benefits as part of social safety nets has the potential to distort individuals labor supply decisions classical economic theory predicts a strong incentive to adjust labor supply and bunch at the discontinuities that arise within notched tax systems however such behavior has been difficult to observe in both survey and administrative data in this paper we design a laboratory experiment to explore the impact of notches on subjects bunching behavior within an environment where subjects receive full information about their payment schedules and can freely adjust their labor supply number of tasks completed while we find clear evidence of bunching under our notched payment system many subjects still fail to bunch we explore the role of behavioral factors such as self control overconfidence and loss aversion as potential determinants of bunching behavior our results indicate that within our sample self control and loss aversion have a positive and significant association with subjects decision to bunch while overconfidence has a negative association these estimates are of the expected sign and suggest that behavioral factors may serve as important underlying determinants of an individual s decision to bunch

unemployment insurance in the united states layoff incentives and cross subsidies we survey unemployment insurance ui in the united states and provide new evidence on the ui payroll tax most ui receipt is due to firms that pay part of the ui costs of their layoffs but weak experience rating leads most firms to pay considerably less than the full costs industries consistently receiving subsidies from the ui system are construction manufacturing and mining finally a large fraction of layoffs resulting in payment of ui are made by firms that are not charged for the costs of the claim because they have employed the individual for less than 2 quarters

a critical appraisal of demand artifacts in consumer research especially since the publication of sawyer s instructive article on the topic consumer researchers have been concerned that demand artifacts significantly compromise the validity and generalizability of experimental findings in this article we provide an overview of the issues surrounding the demand artifacts controversy evaluate the preconditions for demand artifacts and offer a critique of suppositions about the consequences and appropriate control of demand artifacts kellaris and cox s critique of gorn s well known classical conditioning experiments provides the backdrop for much of the discussion

monetary incentives and mood abstract researchers have long debated the methodological necessity of monetary incentives in experimental research the current work shows that financial incentives not only can fail to improve task performance but also can worsen it three studies verify that incentives can elevate mood and that this mood enhancement contributes to worsened task performance the authors discuss implications for the use of incentives in experimental research

uncertain lifetime consumption and dissaving in retirement this paper asks whether the continued accumulation or mild dissaving observed among the retired can be explained by uncertain lifetime in the absence of annuities after an initial period influenced by borrowing constraints under constant relative risk aversion uncertain lifetime depresses consumption by a proportion increasing with age if the elasticity of intertemporal substitution in consumption is small illustrative computations based on actual income and survival data show that plausible elasticities are sufficiently small to give this effect the reduction in consumption is large enough to explain much of the lack of decumulation by the elderly

coherent arbitrariness stable demand curves without stable preferences economic theories of valuation generally assume that prices of commodities and assets are derived from underlying fundamental values for example in finance theory asset prices are believed to reflect the market estimate of the discounted present value of the asset s payoff stream in labor theory the supply of labor is established by the tradeoff between the desire for consumption and the displeasure of work finally and most importantly for this chapter consumer microeconomics assumes that the demand curves for consumer products chocolates cds movies vacations drugs and so forth can be ultimately traced to the valuation of pleasures that consumers anticipate receiving from these products because it is difficult as a rule to measure fundamental values directly empirical tests of economic theory typically examine whether the effects of changes in circumstances on valuations are consistent with theoretical prediction for example whether labor supply responds appropriately to a change in the wage rate whether compensated demand curves for commodities are downward sloping or whether stock prices respond in the predicted way to share repurchases however such comparative static relationships are a necessary but not sufficient condition for fundamental valuation e g summers 1986 becker 1962 was perhaps the first to make this point explicitly when he observed that consumers choosing commodity bundles randomly from their budget set would nevertheless produce downward sloping demand curves

reference points and effort provision a key open question for theories of reference dependent preferences is what determines the reference point one candidate is expectations what people expect could affect how they feel about what actually occurs in a real effort experiment we manipulate the rational expectations of subjects and check whether this manipulation influences their effort provision we find that effort provision is significantly different between treatments in the way predicted by models of expectation based reference dependent preferences if expectations are high subjects work longer and earn more money than if expectations are low

the value of time spent in price comparison shopping survey and experimental evidence the value that consumers place on time spent in price comparison shopping is central to the economics of information theory and models of consumers search behavior yet few empirical studies have examined consumers subjective value of time building on gary becker s work this article presents two tests of a model of the subjective value of time in an effort to explain consumers subjective value of time while they are price comparison shopping the model introduces perceived enjoyment of shopping as a new explanatory variable the findings reveal that respondents incorporate both wage rates and perceived enjoyment of price comparison shopping into their subjective value of time

welfare the earned income tax credit and the labor supply of single mothers during 1984 1996 welfare and tax policy were changed to encourage work by single mothers the earned income tax credit was expanded welfare benets were cut welfare time limits were added and welfare cases were terminated medicaid for the working poor was expanded as were training programs and child care during this same time period there were unprecedented increases in the employment and hours of single mothers we show that a large share of the increase in work by single mothers can be attributed to the eitc and other tax changes with smaller shares for welfare benet cuts welfare waivers training programs and child care programs
