union coverage and profitability among u s firms this paper utilizes unique survey data on labor union coverage at the firm level to examine union effects on the profitability of 705 u s companies during the 1970s market value and earnings are estimated to be about 10 15 percent lower in an average unionized company than in a nonunion company following extensive control for firm and industry characteristics deleterious union effects on firm profitability are sizable throughout the 1972 80 period but vary considerably across industries the relatively poor profit performance of unionized companies may help explain the recent decline in u s union membership the author thanks the w e upjohn institute for employment research for financial support elizabeth gregory for assistance with the union coverage survey zvi griliches for providing access to the rd donald deere terry seaks and anonymous referees for helpful suggestions and seminar participants at connecticut florida state harvard texas a m and william and mary for comments on earlier versions of this research

unfixed resources perceived costs consumption and the accessible account effect consumption depletes one s available resources but consumers may be unaware of the total resources available for consumption and therefore be influenced by the temporary accessibility of resource accounts consistent with this possibility consumers in four experiments perceived a unit of consumption to be smaller and consequently consumed more when large resource accounts of money calories or time e g the money in their savings account were made temporarily accessible compared with when small resource accounts were made temporarily accessible e g the money in their wallet manipulating the cognitive accessibility of resources available for consumption influences both subjective judgment and behavior

paper or plastic how we pay influences post transaction connection does the way that individuals pay for a good or service influence the amount of connection they feel after the purchase has occurred employing a multi method approach across four studies individuals who pay using a relatively more painful form of payment e g cash or check increase their post transaction connection to the product they purchased and or the organization their purchase supports in comparison to those who pay with less painful forms of payment e g debit or credit card specifically individuals who pay with more painful forms of payment increase their emotional attachment to a product decrease their commitment to nonchosen alternatives are more likely to publicly signal their commitment to an organization and are more likely to make a repeat transaction moreover the form of payment influences post transaction connection even when the objective monetary cost remains constant and when the psychological cost is indirect i e donating someone else s money increasing the psychological pain of payment appears to have beneficial consequences with respect to increasing downstream product and brand connection

unions and monopoly profits using cross sectional data for u s manufacturing the author identifies a negative effect of unions on the profits of highly concentrated industries and virtually no effect on the profits of unconcentrated industries the results for concentrated industries are explained in terms of the monopoly model which predicts a negative effect of unions on profits equivalent to the change in employer s surplus the monopoly model also suggests that previous profit studies which omitted the union variable were likely to significantly underestimate the relationship between concentration and profits this prediction is also supported by empirical evidence m sany studies have demonstrated the ability of unions to raise wages above the level of nonunion workers higher union wages in turn may affect the level of prices employment capital intensity productivity and profits recent studies by clark 1982 and freeman 1983 have found significant negative effects of unions on profit rates in the united states using line of business data from 1970 to 1980 for 900 firms clark found a negative effect of unions on the rate of return to capital more specifically the union effects were found to be significantly negative when market shares were low and insignificant when market shares were high according to clark the absence of a union effect in the latter case can be explained by the ability of firms with market power to pass on higher union wages into higher prices 1982 p 47 on the other hand freeman 1983 using data from the survey of manufactures from 1958 to 1976 and the internal revenue service from 1965 to 1976 also found a negative effect of unions on profits contrary to clark s results however the union profit effect was negative only in concentrated industries the point of contention appears to be the role of concentration in determining the union profit effect rather than the overall negative impact of unions the results of clark and freeman are important because previous industrial organization research on profit rates generally ignored unions for instance of the forty six profit studies surveyed by weiss 1974 none included a union variable more recently a profit study in this review by ravenscraft 1983 using high quality line of business data from the federal trade commission also ignored unionization as will be demonstrated the omission of the union variable leads to an understatement of the effect of industrial concentration on profits this means that concentrated industries generate much greater profits than indicated by previous research in order to measure the size of the understatement a new concept employer s surplus is developed which illustrates the theoretical impact of a union wage increase on monopoly profits the empirical estimates of employer s surplus in this paper indicate how monopoly profits are divided between firms and unions most of the data used in this study were obtained from james medoff and charles brown 2 unlike the previous two studies each observation corresponds to a state by two digit sic industry for manufacturing in 1972 because of the large variations in unionization across states this data set offers a useful test of the union profit effect i employer s surplus according to accepted theory the profit maximizing monopolist will employ labor up to the point where the market wage equals the marginal revenue product mrp 3 if for simplicity we assume that all other factors are variable then the mrp curve represents the monopolist s long run demand for labor in the absence of unions employment is determined by the intersection of the mrp curve and nonunion wage wn as pictured in figure 1 if unions raise wages to wa employment will decrease from ln to l with the reducreceived for publication november 28 1983 revision accepted for publication july 6 1984 eastern washington university i am very grateful to dave bunting lisa brown bill dickens claire brown and george strauss for their valuable suggestions on this research this paper is a revised version of chapter 3 from the author s ph d thesis the union impact on profits productivity and prices university of california berkeley 1 see parseley 1980 for a recent review of this literature 2 i would like to thank brown and medoff for making these data available to me 3 marginal revenue product is equal to marginal revenue multiplied by marginal physical product see rees 1979

how economic contractions and expansions affect expenditure patterns in this study we attempt to understand how household budget allocations across various expenditure categories change when the economy is in recession or expansion the common assumption is that a household s tastes would not change as a function of economic conditions and therefore any adjustments in expenditure patterns during economic contractions expansions would simply be due to changes in the consumption budget standard economic models translate these budgetary effects into lateral movements along a set of fixed engel curves which relate category expenditure shares to total expenditures we propose and test a conceptual framework based on the notion of relative consumption which prescribes that for any given total consumption budget expenditure shares for positional goods services will decrease during a recession while shares for nonpositional goods services will increase i e shifting the entire engel curve upward or downward depending on the nature of the expenditure category and the economic conditions

the bottom dollar effect the influence of spending to zero on pain of payment and satisfaction spending that exhausts a budget is shown to decrease satisfaction with purchased products relative to spending when resources remain in the budget six studies including those in which participants earn and spend real resources and evaluate real products explore this bottom dollar effect this research contributes to prior mental accounting research regarding how costs influence decision making e g bundling coupling sunk costs and to the satisfaction literature supporting the role of pain of payment in this process we show that the bottom dollar effect increases as effort required to earn budgetary resources increases decreases in the presence of windfall gains and decreases when there is less time between budget exhaustion and replenishment mediation analyses further demonstrate the role of payment pain in the bottom dollar effect implications are discussed in the context of behavioral research marketing promotions management and public policy

the structural determinants of union bargaining power this paper investigates the structural determinants of variation in union power across manufacturing industries using a pooled sample of unionized establishments from the expenditure on employee compensation surveys of 1968 72 the author estimates wage equations augmented with measures of product market structure bargaining structure and the size distribution of unions the results suggest that union wage gains are greatest where discretionary pricing power enhances employers ability to pay and where unions achieve high coverage practice centralized bargaining and avoid union fragmentation on the other hand centralized bargaining provides no advantage in competitive industries

opportunity cost consideration normatively consumers should incorporate opportunity costs into every decision they make yet behavioral research suggests that consumers consider them rarely if at all this research addresses when consumers consider opportunity costs who considers opportunity costs which opportunity costs spontaneously spring to mind and what the consequences of considering opportunity costs are perceived constraints cue consumers to consider opportunity costs and consumers high in propensity to plan consider opportunity costs even when not cued by immediate constraints the specific alternatives retrieved and the likelihood of retrieval are functions of category structures in memory for a given resource some uses are more typical of the category of possible uses and so are more likely to be considered as opportunity costs consumers who consider opportunity costs are less likely to buy focal options than those who do not when opportunity costs are appealing but no less likely when opportunity costs are unappe

rational and adaptive performance expectations in a customer satisfaction framework this article develops and tests alternative models of market level expectations perceived product performance and customer satisfaction market performance expectations are argued to be largely rational in nature yet adaptive to changing market conditions customer satisfaction is conceptualized as a cumulative construct that is affected by market expectations and performance perceptions in any given period and is affected by past satisfaction from period to period an empirical study that supports adaptive market expectations and stable market satisfaction using data from the swedish customer satisfaction barometer is reported

the union impact on profits evidence from industry price cost margin data this paper uses industry price cost margin data to estimate the extent to which unions reduce profits estimates allowing for the endogeneity of union status are contrasted with estimates that assume union status is exogenous and not determined in part by either profitability or industry structure endogeneity is found to be an important consideration in estimating the union impact on profits two stage estimates are considerably larger than ols estimates the final section explores the total estimated redistribution from capital to labor in the manufacturing sector an important conclusion is that unions raise prices less than was previously believed

in store spending dynamics how budgets invert relative spending patterns the authors conduct four controlled lab experiments and one field study in a brick and mortar grocery store to demonstrate that relative spending the price of the purchased item relative to the mean price of the product category evolves nonlinearly and distinctly for budget and nonbudget shoppers while the relative spending of budget shoppers evolves in a concave manner the relative spending of nonbudget shoppers evolves inversely in a convex manner thus budget nonbudget shoppers spend relatively more less in the middle than at the beginning and toward the end of their shopping trip mediation analyses confirm that the pain of paying experienced while shopping drives price salience which then drives relative spending moreover manipulating shoppers pain of paying by altering the opportunity costs associated with their spending or drawing shoppers attention to their spending via real time spending feedback is shown to influence these spending patterns the research offers theoretical contributions to the in store decision making budgeting and pain of paying literature and has important implications for marketing and promotion strategies in retail and mobile technology environments as it suggests when a shopper may be more sensitive to price related factors

financial deprivation prompts consumers to seek scarce goods consumers assess their well being subjectively largely by comparing the present state of their lives to the state of comparable others and to their own state earlier in time the authors suggest that consumers similarly assess their financial wellbeing and when these evaluations highlight a deficit in their financial position they pursue strategies that mitigate the associated sense of financial deprivation specifically consumers counteract the relative deficit in their financial resources by acquiring goods that are consequently unavailable to other consumers in their environment the results from five studies suggest that the inferiority and unpleasant affect associated with financial deprivation motivates consumers to attend to choose and consume scarce goods rather than comparable abundant goods these effects diminish when scarce goods are limited because other people have already obtained them and when consumers attribute their unpleasant feelings to a source unrelated to financial deprivation

mental budgeting and consumer decisions consumers often set budgets for categories of expenses e g entertainment and track expenses against their budget because budgets cannot perfectly anticipate consumption opportunities people may earmark too much or too little money for a particular category this leads them to overconsume or underconsume goods in that category the results of three studies suggest that consumers do indeed set budgets and that budgeting may lead to underconsumption to show that consumers track expenses the studies demonstrate that budgeting effects are larger for purchases that are highly typical of their category such purchases reduce the amount people spend in a category and block the purchase of other typical items the studies control for satiation and income effects thus budgeting adds predictive power to standard economic consumer theory

a generalizable scale of propensity to plan the long and the short of planning for time and for money planning has pronounced effects on consumer behavior and intertemporal choice we develop a six item scale measuring individual differences in propensity to plan that can be adapted to different domains and used to compare planning across domains and time horizons adaptations tailored to planning time and money in the short run and long run each show strong evidence of reliability and validity we find that propensity to plan is moderately domain specific scale measures and actual planning measures show that for time people plan much more for the short run than the long run for money short and long run planning differ less time and money adaptations of our scale exhibit sharp differences in nomological correlates short run and long run adaptations differ less domain specific adaptations predict frequency of actual planning in their respective domains a very long run money adaptation predicts fico credit scores low planners thus face materially higher cost of credit

the relationship between union wage and profitability effects abstract this paper presents empirical evidence on the relationship between union effects on wages and on profitability as expected unions are found to increase wages albeit significantly in smaller firms only and to reduce profitability in a sample of british engineering firms over the period 1979 1982 the key question asked is whether the observed union effect on profitability is no more than a further manifestation of the observed wage effect estimates of profit equations normalised to take account of the union wage effect do not reject the hypothesis that it is

transaction decoupling how price bundling affects the decision to consume abstract in today s marketplace price bundling is widespread manufacturers and retailers routinely offer multiple products for a single bundled price although the effects of price bundling on purchase behavior have been well researched the effects of price bundling on postpurchase consumption behavior have received almost no attention in this article the authors build on the sunk cost literature e g thaler 1980 1985 and predict that price bundling leads to a disassociation or decoupling of transaction costs and benefits thereby reducing attention to sunk costs and decreasing a consumer s likelihood of consuming a paid for service e g a theater performance four studies show this to be the case in two lab studies the authors show that having a bundled four day ski pass as opposed to four one day ski tickets decreases a person s likelihood of skiing on the final day of a four day ski vacation they replicate this result in a field study showing that multiperformance ticket holders are

the determination of profit margins in uk manufacturing this paper examines the determinants of profit margins in 91 u k manufacturing industries over the period 1983 86 it considers how the inclusion of labor market characteristics in empirical industrial organization specifications affects the estimated concentration margins relationship the empirical work pays detailed attention to the endogenous nature of variables derived from structural industrial organization models the authors report instrumental variables estimates of margins equations in which there emerges a significant role for labor market characteristics indeed both unionization and industrywide unemployment are found to depress profit margins the impact of concentration is seen to be biased downward when these variables are omitted

the effect of partitions on controlling consumption abstract the authors demonstrate that partitioning an aggregate quantity of a resource e g food money into smaller units reduces the consumed quantity or the rate of consumption of that resource partitions draw attention to the consumption decision by introducing a small transaction cost that is they provide more decision making opportunities so that prudent consumers can control consumption thus people are better able to constrain consumption when resources associated with a desirable activity which they are trying to control are partitioned rather than when they are aggregated this effect of partitioning is demonstrated for the consumption of chocolates study 1 and gambles study 2 in study 3 process measures reveal that partitioning increases recall accuracy and decision times importantly the effect of partitioning diminishes when consumers are not trying to regulate consumption studies 1 and 3 finally study 4 explores how habituation may decrease the amount of attention that pa

tracking costs of time and money how accounting periods affect mental accounting after people incur costs to get future benefits they usually track these costs in their mental accounts and are keen to receive the benefits when they become available we introduce the notion that costs and benefits can occur either in the same accounting period day season etc or in different periods our key argument is that monetary costs are tracked across accounting periods but that temporal costs are written off at the end of the period in which they are incurred thus accounting periods lead to a time money asymmetry in the tracking of costs and consequently in the likelihood of seeking benefits in a laboratory study an online panel study and a field study with movie theater patrons we demonstrate how this relationship among accounting periods cost tracking and benefit seeking is different for time than for money our findings offer insights into the sunk cost effect time money differences and mental accounting

unionization and profitability evidence from the capital market this paper examines the effect of unionization on the profitability of firms abnormal monthly common stock returns for a sample of 253 nyse listed firms are estimated for the month in which the union petitions for an election and for the month in which the national labor relations board certifies the election outcome the results suggest that unionization on average is associated with a reduction in equity value when unions win an election the average loss associated with the unionization drive is 3 8 percent of equity value when unions lose an election there is an average net reduction of 1 3 percent in the equity value of the firm

unions and the capture of economic rents an investigation using british firm level data this paper considers the relationship between unions and profitability in a sample of large british firms in 1984 and 1985 the initial finding is that unionised firms have significantly lower profit margins than otherwise comparable non union firms tests of whether the ability of unions to influence profit margins varies with the product and labour market characteristics of the firms in which they are located are then conducted the ability of unions to capture economic rents is seen to be significantly greater in firms which have a high market share and or operate in highly unionised industries

the red and the black mental accounting of savings and debt in the standard economic account of consumer behavior the cost of a purchase takes the form of a reduction in future utility when expenditures that otherwise could have been made are forgone the reality of consumer hedonics is different when people make purchases they often experience an immediate pain of paying which can undermine the pleasure derived from consumption the ticking of the taxi meter for example reduces one s pleasure from the ride we propose a double entry mental accounting theory that describes the nature of these reciprocal interactions between the pleasure of consumption and the pain of paying and draws out their implications for consumer behavior and hedonics a central assumption of the model which we call prospective accounting is that consumption that has already been paid for can be enjoyed as if it were free and that the pain associated with payments made prior to consumption but not after is buffered by thoughts of the benefits that the payments will finance another important concept is coupling which refers to the degree to which consumption calls to mind thoughts of payment and vice versa some financing methods such as credit cards tend to weaken coupling whereas others such as cash payment produce tight coupling our model makes a variety of predictions that are at variance with economic formulations contrary to the standard prediction that people will finance purchases to minimize the present value of payments our model predicts strong debt aversion that they should prefer to prepay for consumption or to get paid for work after it is performed such pay before sequences confer hedonic benefits because consumption can be enjoyed without thinking about the need to pay for it in the future likewise when paying beforehand the pain of paying is mitigated by thoughts of future consumption benefits contrary to the economic prediction that consumers should prefer to pay at the margin for what they consume our model predicts that consumers will find it less painful to pay for and hence will prefer flat rate pricing schemes such as unlimited internet access at a fixed monthly price even if it involves paying more for the same usage other predictions concern spending patterns with cash charge or credit cards and preferences for the earmarking of purchases we test these predictions in a series of surveys and in a conjoint like analysis that pitted our double entry mental accounting model against a standard discounting formulation and another benchmark that did not incorporate hedonic interactions between consumption and payments our model provides a better fit of the data for 60 of the subjects the discounting formulation provides a better fit for only 29 of the subjects even when allowing for positive and negative discount rates the pain of paying we argue plays an important role in consumer self regulation but is hedonically costly from a hedonic perspective the ideal situation is one in which payments are tightly coupled to consumption so that paying evokes thoughts about the benefits being financed but consumption is decoupled from payments so that consumption does not evoke thoughts about payment from an efficiency perspective however it is important for consumers to be aware of what they are paying for consumption this creates a tension between hedonic efficiency and what we call decision efficiency various institutional arrangements such as financing of public parks through taxes or usage fees play into this tradeoff a producer developing a pricing structure for their product or service should be aware of these two conflicting objectives and should try to devise a structure that reconciles them

effects of payment mechanism on spending behavior the role of rehearsal and immediacy of payments past expenses have been shown to influence future spending behavior by depleting available budgets however a prerequisite for this relationship is the accurate recall of past payments and the experiencing of the full aversive impact associated with them this article shows that the use of different payment mechanisms influences both these factors and hence moderates the effects of past payments on future spending specifically past payments strongly reduce purchase intention when the payment mechanism requires the consumer to write down the amount paid rehearsal and when the consumer s wealth is depleted immediately rather than with a delay immediacy two experiments show support for the proposed theoretical framework

the validity of profits structure studies with particular reference to the ftc s line of business data the simple proposition that consumerdamaging collusion is more likely to occur when there are fewer competitors has given rise not only to legal restrictions of economic activity thought to restrict output but also to an enormous amount of empirical work attempting to relate market concentration to the exercise of monopoly power most such studies measured market structure by an index of concentration for example four firm concentration or herfindahl and performance by accounting profit for example net profit divided by assets or price cost margins sales less direct costs divided by sales from the positive statistically significant correlations often found between greater concentration and profit with other factors presumably accounted for some researchers conclude that increases in concentration are anticompetitive and that concentration therefore is bad the concentration profits studies have been criticized essentially on two grounds one is that the positive relationship is not indicative of collusive behavior in particular oliver williamson 1968 john mcgee 1971 harold demsetz 1973 1974 and sam peltzman 1977 point out that higher profits could result from efficiencies experienced by large firms which resulted both in greater market shares and high levels of concentration analytical arguments show that higher profits logically follow as much from lower costs that are associated with higher levels of concentration as from collusion determined higher prices some empirical evidence that supports this belief is presented by demsetz peltzman and bradley gale and ben branch 1982 however their findings have been contested on the grounds that the data used are biased or inadequate or that the researchers have not demonstrated that the observed higher profits greater concentration relationship was caused by lower costs 2 the second criticism is that available data provide an inadequate basis for such conclusions the concentration numbers are based usually on industries defined by the commerce department s standard industrial classifications sic the sic definitions tend to be supply production rather than demand determined include nonhomogeneous products and exclude sales of similar products that are included in different sic groups or are imported the profit data are taken from accounting reports that provide poor measures of economic values weiss 1974 describes many of these problems however he does not believe that these shortcomings invalidate the studies as weiss 1979 concludes

earmarking and partitioning increasing saving by low income households abstract this research examines the effects of earmarking money on savings by low income consumers in particular the authors test two interventions that are designed to enhance the effects of earmarking 1 using a visual reminder of the savings goal and 2 dividing the earmarked money into two parts consistent with prior research suggesting that partitioning increases self control people save more when earmarked money is partitioned into two accounts than when it is pooled into one account in addition the presence of the visual reminder increases the savings rate the authors conclude with implications for consumer welfare and directions for further research

substitution between production labor and other inputs in unionized and non unionized manufacturing the ease of substitution between labor and other factors of production is an important determinant of the elasticity of demand for labor and thus of the economic effects of unionism all else the same the greater the elasticity of substitution the greater is the elasticity of derived demand and the greater the displacement of labor for a given union induced wage increase in sectors where this elasticity is large unions are likely to be relatively weak and able to win only slight wage gains freeman and medoff 1981 and forthcoming or if they win large gains will have to pay a high price in terms of lost jobs in the sectors where the elasticity is small unions may be able to extract a substantial wage premium at little cost in terms of employment moreover as a simple general equilibrium model indicates the elasticity of substitution between labor and other factors in the unionized sector is a key parameter in determining the impact of the iiunion wage effect on the earnings of nonunion workers and on the efficiency of the economy johnson and mieskowski 1970 despite the importance of the elasticity of labor demand for an analysis of unionism little attention has been given to the absolute and relative magnitude of this elasticity under collective bargaining while there is some discussion of technological change and the substitution of capital and nonproduction workers for organized production workers in the institutional literature e g slichter 1941 slichter healy and livernash 1960 bok and dunlop 1970 modern econometric work provides no estimates of the relevant parameters as a result johnson and mieskowski 1970 rees 1963 lewis 1964 and others have been forced to evaluate union effects with guesstimates of the elasticities of concern in union settings this paper attempts to fill some of the gap in our knowledge by providing estimates for u s manufacturing of the constant output elasticity of demand for unionized and nonunionized production workers and of the elasticity of substitution between these workers and other inputs the analysis concentrates on what we call the relative inelasticity hypothesis which states that the demand for production workers will be more inelastic in the presence of a union for two reasons the likelihood that unions have organized and survived in sectors with low elasticities and the effects of various contract provisions on the ability of management to substitute other factors for production labor the study is divided into four sections section i develops the rationale for the relative inelasticity hypothesis and describes the nature of the empirical analysis conducted to test its validity the second section uses a 1972 state by 2 digit standard industrial classification sic industry data file for manufacturing to estimate the elasticity of substitution between production labor and both nonproduction labor and capital in the union and nonunion sectors of u s manufacturing industries section iii provides estimates based on a 1968 72 sample of manufacturing establishments of the elasticity of substitution between production and nonproduction labor the only two inputs for which information is available the final section briefly summarizes the findings and discusses their implications for understanding the impact of trade unionism on the u s economy to preview the ensuing discussion our main conclusion is substitution between production labor and other inputs is generally lower in union received for publication march 6 1978 revision accepted for publication august 17 1981 both authors are with harvard university and the national bureau of economic research supported by u s department of labor grant no j 9 m 6 0094 national science foundation grant no apt77 16279 and the national bureau of economic research under its program of research on labor economics we are especially grateful to jane mather for her invaluable assistance on this project and to greg bialecki charles brown gary chamberlain kathy coons jon fay martin van denburgh and lori wilson for their significant contributions the study has not been reviewed by the board of directors of the national bureau

margins concentration unions and the business cycle theory and evidence for britain abstract a number of recent studies have examined the cyclical relationship between price cost margins concentration and unions u s data has concluded that unions reduce margins margins vary over the cycle and concentration unionisation and the cycle interact in their effect on margins however there is almost no theory to account for these results we propose a simple theory that assumes only that there is overhead labour present at the firm this produces theoretical predictions that can explain these results and discriminate between existing theories we present results of our own using u k panel data and show similar findings to the u s

payment depreciation the behavioral effects of temporally separating payments from consumption research suggests that individuals mentally track the costs and benefits of a consumer transaction for the purpose of reconciling those costs and benefits on completion of the transaction prelec and loewenstein 1998 thaler 1980 1985 in transactions where costs precede benefits this can lead to a systematic and economically irrational attention to sunk costs arkes and blumer 1985 thaler 1980 in this article we consider economic exchanges in which costs significantly precede benefits as with many prepayment types of consumer transactions we predict a consumer will gradually adapt to a historic cost with the passage of time thereby decreasing its sunk cost impact on the consumption of a pending benefit we label this process of gradual adaptation to costs payment depreciation in a series of experiments we find evidence of payment depreciation across a range of consumer transactions and offer insight into the behavioral implications of temporally separating costs from benefits

waiting time and decision making is time like money time is a resource as such consumers have to make decisions regarding their use of time in the purchase and consumption of goods and services using prospect theory and mental accounting as theoretical frameworks this article investigates whether consumers treat time like money when they make decisions in a series of studies we found that the value of consumers time is not constant but depends on contextual characteristics of the decision situation our results also suggest that in deterministic situations people make decisions involving time losses in a manner consistent with the convex loss function proposed by prospect theory however in decision making under conditions of risk people seem to make risk averse choices with respect to decisions in the domain of time in contrast to the risk seeking behavior often found with respect to decisions involving losses of money we discuss the nonfungibility of time as an explanation for the discrepancy between decisions involving time and those involving money

when choosing makes a good thing better temporal variations in the valuation of hedonic consumption abstract this research investigates how the valuation of delayed consumption of hedonic products such as concerts and chocolate varies with the passage of time between choice and consumption the authors find that when consumers make their own choices they exhibit increases in evaluations of delayed consumption but only if the interval between choice and consumption is relatively short the effect attenuates over longer periods resulting in an inverted u shaped relationship between evaluations and time in contrast when somebody else chooses the same option for the consumer evaluations decrease with the passage of time these effects depend on the extent of intrinsic motivation toward the object of consumption and occur only for consummatory consumption that is of inherent interest moreover anticipatory increases in evaluations before consumption have ironic negative effects on postconsumption evaluations the authors discuss implications and directions for further research

spending time versus spending money we find systematic differences in the way that people spend time versus money ex post people are able to more easily accommodate negative outcomes by adjusting the value of their temporal inputs ex ante people are willing to spend more time for higher risk higher return options whereas when spending money the pattern is reversed and the more standard pattern of increasing risk aversion is observed although accurate assessment of the opportunity costs of time is key to making good decisions ambiguity in the value of time promotes accommodation and rationalization

union membership determination and industry characteristics recent literature on the economics of unionism has expanded beyond its customary focus on the wage and nonwage effects of collective bargaining and given increased attention to the determinants of union membership previous union membership studies have been couched primarily within an individual choice framework whereby utility maximizing individuals choose either to join or not to join a union empirical work typically treats membership as a function of some vector of personal characteristics 1 2 10 11 21 it is our contention that such studies can best be interpreted as explaining the determination of the union status of jobs and that several industry and firm characteristics in addition to personal characteristics can be expected to affect significantly union membership in this paper theory and evidence relating to the effects of firm and industry characteristics on union membership are presented industry level data are bridged with a large microdata set containing individual characteristics in order to examine the determinants of unionism among workers in manufacturing utilizing a simultaneous model and controlling for sample selection bias we find that product market concentration capital intensity establishment size and job risk significantly affect the likelihood of union membership
