giving firms an e for effort consumer responses to high effort firms this research shows that consumers reward firms for extra effort more specifically a series of three laboratory experiments shows that when firms exert extra effort in making or displaying their products consumers reward them by increasing their willingness to pay store choice and overall evaluations even if the actual quality of the products is not improved this rewarding process is defined broadly as general reciprocity consistent with attribution theory the rewarding of generally directed effort is mediated by feelings of gratitude when consumers infer that effort is motivated by persuasion however they no longer feel gratitude and do not reward high effort firms

unemployment and crime rates in the post world war ii united states a theoretical and empirical analysis using annual time series data for the united states 1946 1982 two hypotheses are tested 1 the level of the unemployment rate in any given year will have a negative partial contemporaneous effect on detrendedfluctuations increases or decreases in seven index crime rates homicide rape aggravated assault robbery burglary larceny theft and motor vehicle theft in that year 2 unemployment rate fluctuationsfrom one year to the next will have a positive partial effect on detrended crime rate fluctuations in the next year these hypotheses are developed from a theoretical model that identifies the former with a criminal opportunity effect and the latter with a criminal motivation effect of aggregate unemployment on crime for burglary robbery and larceny theft empirical support is found for the expected pattern of partial effects however the relative sizes of the effects are such that the total impacts of unemployment through both partial effects are negative in addition only the negative levels effect is exhibited for homicide and motor vehicle theft while rape and aggravated assault show no consistent association with either levels orfluctuations in the unemployment rate interpretations for these findings are discussed

market wages and youth crime to study the problem of widespread youth crime i analyze a timeallocation model in which consumers face parametric wages and diminishing marginal returns to crime the theory motivates an econometric model that i estimate using data from the national longitudinal survey of youth my estimates suggest that youth behavior is responsive to price incentives and that falling real wages may have been an important determinant of rising youth crime during the 1970s and 1980s moreover wage differentials explain a substantial component of both the racial differential in criminal participation and the age distribution of crime

anticipation and the valuation of delayed consumption this paper presents a model of intertemporal choice that incorporates savoring and dread i e utility from anticipat ion of delayed consumption the model explains why an individual with positive time preference may delay desirable outcomes or get unpleas ant outcomes over with quickly contrary to the prediction of convent ional formulations of intertemporal choice implications of savoring and dread for savings behavior empirical estimation of discount rate s and public policy efforts to combat myopic behavior are explored the model provides an explanation for common violations of the indepe ndence axiom as applied to intertemporal choice copyright 1987 by royal economic society

research note customer loyalty programs are they profitable loyalty programs are very common in practice many researchers have worked at understanding the impact of loyalty programs on market competition and the mechanism behind it interestingly almost all of the studies have explored a symmetric equilibrium where both of the competing firms offer a loyalty program to our knowledge the extant literature has not investigated in depth whether asymmetric equilibrium can exist where only one firm chooses to offer a loyalty program and the other firm chooses to compete via lowering prices such a question is important because some markets do support such asymmetric equilibriums with respect to loyalty programs also the existence of asymmetric equilibrium shows that a loyalty program need not be profitable for some firms in this paper we use a game theoretic framework to investigate specific types of customer loyalty programs that provide benefit to loyal customers in the form of discount over market prices the model considers consumer switching and includes two types of consumer heterogeneity the first type of heterogeneity concerns the differences between customers with respect to their liking for loyalty programs and the second type concerns the differences among the loyalty program members with respect to their ability to collect enough loyalty points to redeem loyalty rewards by analyzing a duopoly market we find that both symmetric equilibrium i e where both competing firms offer the loyalty program and asymmetric equilibrium i e where one firm alone offers the loyalty program can be sustained the paper explores conditions for the existence of these two equilibriums

do workers prefer increasing wage profiles we present survey data challenging the assumption implicit in analyses of labor supply that all else being equal workers prefer declining over increasing wage profiles we test several explanations for our results including that a there is something special about wages e g their association with productivity as opposed to other types of payments that induces the preference for increasing wages b utility depends not only on absolute levels of consumption but also on changes in consumption over time and c respondents who prefer increasing wage profiles are irrational and would change their behavior if the rationale for preferring declining wages were explained

the effects of labor markets and income inequality on crime evidence from panel data we estimate a model of crime using panel data for the u s we focus on the role of labor markets income distribution and demographics on property crime we find strong evidence that favorable labor market conditions have a significant negative effect on property crime we further test this result using sector specific wages and find that crime is most elastic with respect to wages in sectors that use low skilled labor we also find that income inequality has no significant effect on crime and that the proportion of young males in the population has a significant positive effect on crime

public sector capital and the productivity puzzle a number of studies have suggested a quantitatively important relationship between public sector capital accumulation and private sector productivity with the most compelling evidence derived from analyses of state level data estimates herein of production functions that use standard techniques to control for unobserved state specific characteristics however reveal essentially no role for public sector capital in affecting private sector productivity only estimates of state production functions that do not include such controls find substantial productivity impacts this result reconciles existing econometric estimates with the findings of hulten and schwab based on growth accounting techniques as such techniques effectively control for state specific effects region level estimates are essentially identical to those from state data suggesting no quantitatively important spillover effects across states copyright 1994 by mit press

estimating the economic model of crime with panel data previous attempts at estimating the economic model of crime with aggregate data relied heavily on cross section econometric techniques and therefore do not control for unobserved heterogeneity this is even true of studies that estimated simultaneous equations models using a new panel data set of north carolina counties the authors exploit both single and simultaneous equations panel data estimators to address two sources of endogeneity unobserved heterogeneity and conventional simultaneity their results suggest that both labor market and criminal justice strategies are important in deterring crime but that the effectiveness of law enforcement incentives has been greatly overstated copyright 1994 by mit press

quality distortion by a discriminating monopolist the standard model of monopolistic imperfect quality discrimination involving consumer self selection has shown that no distortion occurs at the highest quality level while all lower quality levels are degraded in order to maintain profitable market segmentation this result flows from the assumption that consumers with a higher total utility of quality also have a higher marginal utility of quality the paper develops a reasonable model in which the standard assumption is not satisfied and this alternative model yields vastly different conclusions regarding the form of quality distortion in particular quality may be enhanced not degraded to maintain profitable market segmentation copyright 1989 by american economic association

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

monopoly provision of product quality and warranties an exploration in the theory of multi dimensional screening we address the monopoly problem of designing and pricing a product line of goods distinguished by different quality and warranty levels consumers vary in their evaluations of these attributes so that the problem is one of screening it is sufficiently complex that the local approach commonly used does not work instead we use new techniques for dealing with incentive constraints between nonadjacent consumer types these techniques allow us to characterize optimal allocations that may not be monotonic in particular although the more eager types of buyer do pay higher prices and yield the monopoly higher profit they may receive lower quality or lower warranty coverage we find preference restrictions that restore monotonicity concave risk tolerance implies that warranty coverage increases in type and constant absolute risk aversion implies that quality increases in type

it s not what you get but when you get it the effect of gift sequence on deposit balances and customer sentiment in a commercial bank abstract the authors examine the impact of gifts on deposit balances and customer satisfaction in a longitudinal field experiment conducted at a commercial bank they find that gifts increased deposit balances survey response rates and customer satisfaction compared with the no gift control they manipulated several factors within the gift treatment gift type the accompanying message and the sequence of gift value which improved 35 then 100 gift worsened 100 then 35 gift or was a single gift a highly detrimental effect of decreasing gift value occurred on deposit balances this deterioration aversion persisted in a long term follow up analysis of deposit balances a vignette experiment replicates deterioration aversion and extends the results demonstrating increased effectiveness of improving gifts over constant gift sequences and indicating that the mechanism underlying deterioration aversion involves the violation of expectations

estimations of the economic model of crime using aggregate and individual level data much has happened in the economics of crime since becker s 1 seminal paper of two decades ago the theory has been refined by among others ehrlich 10 11 12 block and lind 4 5 block and heinke 3 and schmidt and witte 30 attempts to test the model empirically began immediately the most cited including ehrlich 10 11 12 sjoquist 31 carr hill and stern 7 phillips and votey 26 witte 38 and myers 22 23 interest continues with recent work including layson 19 sandelin and skogh 29 ehrlich and brower 13 cover and thistle 9 viscusi 36 and tauchen witte and griesinger 33 there has been some controversy however concerning the type of data more suitable to the estimation of the economic model of crime most of the work has used aggregate data in which the unit of observation is a political jurisdiction but the use of aggregate data has been sharply criticized the alternative is individual data few attempts have been made to use individual data probably because an ideally constructed data set representative of a general population would be far too costly for most research budgets most of the studies that have been done have used data on releasees from prison or other criminal justice programs they are in effect recidivism studies based on the economic model of crime

reference dependent consumption plans we develop a rational dynamic model in which people are loss averse over changes in beliefs about present and future consumption because changes in wealth are news about future consumption preferences over money are reference dependent if news resonates more when about imminent consump tion than when about future consumption a decision maker might to generate pleasant surprises overconsume early relative to the optimal committed plan increase immediate consumption following surprise wealth increases and delay decreasing consumption following surprise losses since higher wealth mitigates the effect of bad news people exhibit an unambiguous first order precautionary savings motive

help wanted economists crime and public policy beginning with gary w becker s 1968 article on crime and punishment economists have contributed important theoretical insights and empirical findings to the study of criminal behavior but the influence of economists on crime relevant research and over policy debates remains negligible this essay summarizes some basic data on the causes of crime the social costs and benefits of incarceration and replenishing social capital work on crime by economists should become influential in setting research agendas and shaping policy debates but economists will have to roll up their sleeves complexify their models and confront a real world prisoner s dilemma or two

wages seniority and the demand for rising consumption profiles abstract in many occupations wages rise faster than productivity over the life cycle other authors have suggested a variety of explanations for this pattern we argue that these explanations fail for at least two occupations commercial airline pilots and intercity bus drivers we then explore an alternative explanation based on the assumption that satisfaction depends on not only the level of consumption but also its rate of change we argue that upward sloping wage profiles are an expedient substitute for personal savings as a means for achieving upward sloping consumpion profiles

are wages habit forming evidence from micro data although utility functions play a central role in economics the axiom that utility depends only on the absolute levels of its arguments is rarely tested this paper uses panel data on 2000 british employees who remain with the same employer and who are not promoted from one wave to the next it is shown that one important measure of well being overall job satisfaction is strongly positively correlated with the change in the worker s pay between waves but is unrelated to the current level of pay empirical tests suggest that a reference dependent satisfaction function where individual well being depends on current pay relative to past pay is more consistent with these regression results than are productivity or agency explanations of increasing wage profiles some evidence is presented of greater job satisfaction effects of pay rises for lower paid less well educated and younger workers these results provide some micro evidence consistent with the theory widespread in social science of habituation individuals may become used to any given level of consumption or income as such they tie in with the finding that a country s well being as measured by the average happiness of its citizens is only weakly correlated with its per capita gnp
