work hours wages and vacation leave using the panel study of income dynamics the authors provide a set of facts about vacation leave they show that on average vacation time taken rises one to one with paid vacation annual hours worked fall by about one full time week with every week of paid vacation the amount by which vacation time taken exceeds time paid is highest for women union members and government workers paid vacation weeks are positively associated with hourly wage rates and to a lesser extent with nonwage compensation and vacation time taken is weakly countercyclical vacation leave seems to be determined by broad employer policy rather than by negotiation between the worker and the firm in particular it is strongly related to seniority but depends very little on labor market experience and for job changers it is only weakly related to vacation on the previous job

contingent democrats industrialists labor and democratization in late developing countries many classic works of political economy have identified capital and labor as the champions of democratization during the first wave of transition by contrast this article argues for the contingent nature of capital and labor s support for democracy especially in the context of late development the article offers a theory of democratic contingency proposing that a few variables namely state dependence aristocratic privilege and social fear account for much of the variation found in class support for democratization both across and within cases conditions associated with late development make capital and labor especially prone to diffidence about democratization but such diffidence is subject to change especially under the impact of international economic integration poverty reducing social welfare policies and economic growth that is widely shared case material from korea indonesia mexico zambia brazil tunisia and other countries is offered as evidence

individual and aggregate labor supply with coordinated working times i analyze two extensions to the standard model of life cycle labor supply that feature operative choices along both the intensive and extensive margin one assumes that individuals face continuous wage hours schedules while the other assumes that all work must be coordinated across individuals though similar qualitatively the two models have very different implications for aggregate labor supply responses to tax policy in the first model curvature in the individual utility from leisure function plays relatively little role but in the second model it is of first order importance the second model also has important implications for what data are best able to provide evidence on the extent of curvature in the utility from leisure function

procedural unfair wage differentials and their effects on unethical behavior in this paper we investigate how payment procedures that are deemed unfair can spur unethical behavior towards innocent coworkers in a real effort experiment in our discrimination treatment a highly unfair payment procedure with wage differentials half the workforce is randomly selected and paid by relative performance whereas the remaining receives no payment a joy of destruction game measures unethical behavior subsequently non earners in discrimination destroy significantly more than in the non discriminatory control treatments in discrimination unethical behavior is generally high for all non earners independent of individual inequality aversion and relative performance beliefs in the control treatments inequality aversion is the main driver of destructive behavior

envy in mission oriented organizations according to the labor donation theory workers adhering to their firms mission are willing to donate a portion of their paid labor in this paper we study how workers fairness concerns limit the firm s ability to extract labor donation from its employees we find that in sectors where the firm s mission is important optimal contracts are such that high ability employees perceive their wage as less fair than low ability employees and they must be rewarded with an envy rent the opposite is true in sectors where the firm s mission does not play a relevant role we empirically test the predictions of the model using the german socio economic panel finding support for our theoretical results

the effect of food stamps on labor supply a bivariate selection model abstract although there is a large literature on the effects of u s transfer programs on labor supply this is the first such study of the food stamp program we model the nonlinearity and nonconvexity of the budget constraint and use maximum likelihood methods to estimate hours of work functions for female heads of household the largest recipient group in the program we also model the joint response to afdc and food stamps and we account for the existence of a significant number of eligible households who do not participate in the programs a three equation bivariate selection model is estimated on a sample of eligible households with maximum likelihood

labour supply estimation and public policy abstract economists devote considerable energies towards refining their econometric techniques to overcome difficulties connected with conducting empirical research despite advances in technique it is not clear whether further refinement in this direction is worthwhile for policy purposes it may be that no further amount of statistical adjustment of inadequate data will increase understanding and that better data is simply necessary to add to our knowledge but rarely is sufficient credit paid to new forms of data in short econometric technique is emphasized to the neglect of data innovation as if new data were merely lying about waiting for an ingenious suggestion for use this paper surveys advances of the last twenty five years in estimating labour supply for policy purposes with a view towards appreciating the relative contribution of both improvements in econometric technique as well as developments of new data after briefly detailing the key parameters which economists have sought to estimate we describe the early first generation research circa 1970 which is plagued by problems of unobservable variables measurement errors truncation and selectivity bias and non linear budget constraints second generation research constitute attempts to resolve one or more of these difficulties and the respective contribution of econometric technique and new data is acknowledged and assessed including the contribution of data generated by large scale social experiments in which participants are randomly assigned to different guaranteed income plans and their labour supply behaviour measured

the political economy of income distribution in south korea the impact of the state s industrialization policies abstract a number of previous studies of economic growth and income distribution in south korea based largely on 1960s data concluded that south korea was an exception to kuznets inverse u pattern of income inequality also it was regarded as an exception to the usual negative consequences predicted by dependency theory for an economy so dependent on foreign capital and world markets this author presents more recent data for the 1970s and early 1980s in order to support his claim that the trend toward income equality that appeared in the 1960s was reversed in the 1970s the author develops a thesis that stresses the role of the state in shaping the korean political economy he argues that it has been the strong south korean developmentalist state in firm control of both domestic and foreign capital and its export oriented industrialization policies that have been the principal determinant of the pattern of income distribution he contests the usual explanation related to the level of economic development or external dependency per se

strikes scabs and tread separations labor strife and the production of defective bridgestone firestone tires this paper provides a case study of the effect of labor relations on product quality we consider whether a long contentious strike and the hiring of permanent replacement workers by bridgestone firestone in the mid 1990s contributed to the production of an excess number of defective tires using several independent data sources we find that labor strife in the decatur plant closely coincided with lower product quality count data regression models based on two data sets of tire failures by plant year and age show significantly higher failure rates for tires produced in decatur during the labor dispute than before or after the dispute or than at other plants also an analysis of internal firestone engineering tests indicates that p235 tires from decatur performed less well if they were manufactured during the labor dispute compared with those produced after the dispute or compared with those from other non striking plants monthly data suggest that the production of defective tires was particularly high around the time wage concessions were demanded by firestone in early 1994 and when large numbers of replacement workers and permanent workers worked side by side in late 1995 and early 1996

fair wages and effort provision combining evidence from a choice experiment and a field experiment the presence of workers who reciprocate higher wages with greater effort can have important consequences for firms and labor markets knowledge about the extent and determinants of reciprocal effort choices is however incomplete we investigate the role of fairness perceptions and social preferences in a field experiment in which workers were hired for a one time job we show that workers who perceive being underpaid at the base wage increase their performance if the hourly wage increases whereas those who feel adequately paid or overpaid at the base wage do not change their performance moreover we find that only the workers who display reciprocity in a choice experiment show reciprocal effort responses in the field the workers who lack reciprocity in the choice experiment do not respond to the wage increase even if they feel underpaid at the base wage our findings suggest that fairness perceptions and social preferences are key in workers performance response to wage increases in our study the wage increase affects effort mainly through the removal of perceived unfairness i e the elimination of negative reciprocity toward the firm rather than positive reciprocity these results are the first direct evidence of the fair wage effort hypothesis in the field and also help interpret previous contradictory findings in the literature data as supplemental material are available at http dx doi org 10 1287 mnsc 2014 1970 this paper was accepted by uri gneezy behavioral economics

an adverse social welfare effect of a doubly gainful trade abstract acknowledging individuals distaste for low relative income renders trade less appealing when trade is viewed as a technology that integrates economies by merging separate social spheres into one we define a trembling trade as a situation in which gains from trade are overtaken by losses of relative income with the result that global social welfare is reduced a constructive example reveals that a trembling trade can arise even when trade is doubly gainful in that it increases the income of every individual and narrows the income gap between the trading populations

micro and macro elasticities in a life cycle model with taxes we build a life cycle model of labor supply that incorporates changes along both the intensive and extensive margin and use it to assess the consequences of changes in tax and transfer policies on equilibrium hours of work we find that changes in taxes have large aggregate effects on hours of work moreover we find that there is no inconsistency between this result and the empirical finding of small labor elasticities for prime age workers in our model micro and macro elasticities are effectively unrelated our model is also consistent with other cross country patterns

the structure of labor costs with overtime work in u s jobs the author analyzes employment contract and labor demand models of the fair labor standards act overtime pay regulation to determine their effects on employers labor costs using national compensation survey data to obtain a representative sample of u s private industry jobs he assesses each model s ability to predict either the adjustment of wage rates if overtime is warranted the employment contract model or the probability of using overtime to meet labor demands the labor demand model using quasi fixed employment costs as independent variables allows for a better accounting of labor demand he finds that lower wages go hand in hand with jobs requiring more overtime work which indicates that overtime pay regulation influences the structure of compensation

are workers paid their marginal products status is like coase s social costs a reciprocal phenomenon given that one person s gain in status can occur only at the expense of a loss in status for others and that workers are free to choose their coworkers it follows that the competitive wage structure within a firm must be one in which individual wage differences understate individual differences in marginal products the purpose of this paper is to examine a variety of empirical evidence that relates to this proposition about the firm s internal wage structure the paper is organized as follows section i briefly summarizes the theoretical considerations that govern competitive wage determination when status matters to people and firms are viewed as voluntary associations of workers section ii then confronts the predictions of section i by examining pay and productivity schedules for a group of sales occupations for which these schedules are relatively easily observed section ii also examines the relationship between wages and productivity for a sample of university professors an occupation in which individual productivity differences are for a variety of obvious reasons relatively more difficult to measure all of the evidence examined is consistent with the hypothesis that within firms wage rates vary substantially less than do individual productivity values section iii discusses additional observations and evidence that bear on this same hypothesis it suggests that the implicit market for status may strongly influence the ways in which firms are organized to carry out the tasks they perform section iv concludes by considering the claim that egalitarian internal wage structures arise because of equity considerations it argues that the concept of equity appears very closely linked to the concept of status and suggests a strategy for assigning monetaty value to the equity considerations that so often dominate public policy decisions

labor supply hours constraints and job mobility if hours can be freely varied within jobs the effect on hours of changes in preferences for those who do change jobs should be similar to the effect on hours for those who do not change jobs conversely if employers restrict hours choices then changes in preferences should affect hours more strongly when the job changes than when it does not change for a sample of married women we find that changes in many of the labor supply preference variables produce much larger effects on hours when the job changes

the estimation of a joint wage hours labor supply model in this paper the standard cross sectional static model of labor supply is modified to make the wage endogenous and a joint wage hours model is estimated the econometric technique addresses the non linearity of the budget constraint by approximating the constraint by a series of discrete points the results show that the budget constraint is indeed nonlinear that hours affect the wage quadratically that true wage elasticities are lower as a result and that the model fits the hours distribution much better than the standard tobit model

intrinsic motivation and incentives workers act in the interests of their employ ers for a host of reasons sometimes money is the motivation but often it is because they care about what they do despite the importance of such intrinsic motivation the economic litera ture has offered little in terms of understanding relevant trade offs when alignment of inherent preferences rather than monetary interests is what motivates people 1 instead the literature has focused largely on the efficiency gains that arise from agents sharing the preferences of their employers 2 this paper offers such a theory of intrinsic motivation where firms partially solve agency problems by hiring agents with particu lar preferences unlike the previous literature i show that firms in general hire agents who do not share their interests instead agents are disproportionately motivated to carry out a sub set of what the firm cares about specifically i show that the institution hires the agent with similar preferences to himself only in the limit ing case where the agent s preferences are irrel evant namely when output can be perfectly contracted on instead the optimal response of the institution is to hire biased agents with the degree of bias increasing as contracting mea sures get worse the reason for this is rather simple that jobs within firms are specialized so for example some people make things others design them yet other sell them and so on similarly aca demics do research deans raise money admin istrators do the books social workers provide services to clients while their superiors are charged with cost control etc the principal novelty of this paper is to show how hiring practices and specifically the intrinsic moti vation of those hired changes as the ability to contract worsens in a world where tasks are specialized in doing so it paints a picture of firms responding to noncontractibility by hiring agents with very extreme interests at the cost of their ignoring other aspects of their jobs so for example if the output of a social worker cannot be measured a natural response will be to hire agents who are highly motivated to get benefits to clients at the cost of their ignoring things like cost control simple though this observation is it illustrates a cost to using intrinsic motiva tion namely the endogenous hiring of those who increasingly care only about one aspect of their job in this way the simple model outlined here lays the foundation for a view of poor contracting firms as fiefdoms where those with extreme competing interests reside a point i elaborate on elsewhere prendergast 2008 for a theory of intrinsic motivation to be use ful firms must have some control over it the central assumption here is that firms have some ability to hire employees based on these intrin sic preferences i build a model of an institution that carries out two activities say service pro vision and cost control it employs two agents to do so the tasks are somewhat specialized in that one agent primarily but not exclusively does service provision and the other primarily does cost control the institution has an objec tive that trades off these two components and has a performance measure that can reward agents the firm also chooses whom to hire potential discussant robert gibbons massachusetts institute of technology

towards a micro founded theory of aggregate labour supply we build a heterogeneous agents life cycle model that captures a large number of salient features of individual male labour supply over the life cycle by education both along the intensive and extensive margins the model provides an aggregation theory of individual labour supply firmly grounded on individual level micro evidence and is used to study the aggregate labour supply responses to changes in the economic environment we find that the aggregate labour supply elasticity to a transitory wage shock is 1 75 with the extensive margin accounting for 62 of the response furthermore we find that the aggregate labour supply elasticity to a permanent compensated wage change is 0 44

social comparison and effort provision evidence from a field experiment social comparison has potentially far reaching consequences in many economic domains we conducted a field experiment to examine how social comparison affects workers effort provision if their own wage or that of a co worker is cut workers were assigned to groups of two performed identical individual tasks and received the same performance independent hourly wage cutting both group members wages caused a decrease in performance but when only one group member s wage was cut the affected workers decreased their performance more than twice as much as when both workers wages were cut this finding indicates that social comparison among workers affects effort provision because the only difference between the two wage cut treatments is the other group member s wage level in contrast workers whose wage was not cut but who witnessed their group member s pay being cut displayed no change in performance relative to the baseline treatment in which both workers wages remained unchanged this indicates that social comparison exerts asymmetric effects on effort jel c93 j33 m53

effort and comparison income experimental and survey evidence the authors test the hypothesis that individual effort on the job depends both on one s own income and on the individual s position in the relevant income distribution combining experimental evidence from a gift exchange game with multi country issp survey data they analyze the extent to which relative income affects an individual s effort finding that an individual s rank in the income distribution more strongly determines effort than does others average income which suggests that comparisons are more ordinal than cardinal their experiment also reveals that comparisons over time affect effort individuals who received higher income offers or enjoyed higher income rank in the past exerted lower levels of effort for a given current income and rank

organization design proximity and productivity responses to upward social comparison we investigate the mechanisms that shape social comparison in organizations and generate social comparison costs in particular we focus on heterogeneity in the strength and type of incentives and argue that from an efficient design perspective such variance in rewards is a double edged sword while the sorting and incentive effects that result may increase productivity the social comparison processes that arise may dampen it we posit that the mechanisms underlying these behavioral costs are shaped not only by the magnitude of reward variance but by the formal and informal design elements shaping the distance of advantaged peers in other words the more proximate socially structurally or geographically are those to whom one socially compares the larger the behavioral response empirically we use an unanticipated event during which outlets of a bank previously operating under essentially homogenous incentives were assigned to tournament groups with differing ex ante probabilities of winning a

teacher performance pay experimental evidence from pakistan this paper presents evidence from the first three years of a randomized controlled trial of a government administered pilot teacher performance pay program in punjab pakistan the program offers yearly cash bonuses to teachers in a sample of public primary schools with the lowest mean student exam scores in the province bonuses are linked to three school level indicators the gain in student exam scores the gain in school enrollment and the level of student exam participation bonus receipt and size are also randomly assigned across schools according to whether or not the teacher is the school s head on average the program increases school enrollment by 4 1 percent and student exam participation rates by 3 4 percentage points both in the third year the analysis does not find that the program increases student exam scores in any year mean impacts are similar across program variants the positive mean impact on school enrollment is mainly seen in urban schools and the positive mean impact on student exam participation rates is only seen in rural schools

on the evidence of a working spouse penalty in the managerial labor market this analysis of march 1993 current population survey data suggests that managers with working wives earn lower wages than their counterparts with non working wives the labor supply decisions of managers wives appear to be unaffected by that is exogenous with respect to their husbands wages in contrast there is evidence that the labor supply decisions of non managers wives are affected by their husbands wages and when the analysis takes account of that endogeneity it is found that non managers do not suffer a working spouse penalty the analysis also highlights some important issues related to the use of instrumental variables

gift giving and worker productivity evidence from a firm level experiment abstract we present results from a field experiment designed to measure worker response to a monetary gift from their employer the experiment took place inside a tree planting firm paying its workforce incentive contracts firm managers told a crew of tree planters they would receive a pay raise for one day as a result of a surplus not attributable to past planting productivity we compare planter productivity the number of trees planted per day on the day the gift was handed out with productivity on previous and subsequent days of planting on the same block and thus under similar planting conditions we find direct evidence that the gift had a significant and positive effect on daily planter productivity controlling for planter fixed effects weather conditions and other random daily shocks

piece rates fixed wages and incentives evidence from a field experiment data from a field experiment are used to estimate the gain in productivity that is realized when workers are paid piece rates rather than fixed wages the experiment was conducted within a tree planting firm and provides daily observations on individual worker productivity under both compensation systems unrestricted statistical methods estimate the productivity gain to be 20 since planting conditions potentially affect incentives structural econometric methods are used to generalize the experimental results to out of sample conditions the structural results suggest that the average productivity gain outside of the experimental conditions would be at least 21 7

the demand for leisure time in the presence of constrained work hours w douglass shaw this article presents a labor supply model designed to address situations of overemployment or underemployment in the labor market previous labor supply models have taken the possibility of work hour constraints into consideration but typically assumed that the existence of fixed work hours only influenced the decision of labor force participation this ignores situations in which individuals choose to be employed at fixed hour jobs even though these jobs do not offer the desired work hours jel j22 i introduction early attempts to incorporate time into consumer theory such as those by becker 1965 and by deserpa 1971 and to explain behavior in labor markets such as heckman s 1974 pioneering study relied on the assumption that individuals are able to freely adjust the hours they work the ability of an individual to achieve equilibrium in these models depends on flexible work hours for many individuals however hours of work are likely to be constrained individuals wishing to increase or decrease their work time may face a decision of either accepting the fixed hour schedule or exiting the labor force more refined models of labor force participation put forth by moffitt 1982 tummers and woittiez 1990 and zabel 1993 recognized this by incorporating a fixed hour constraint directly into the labor force participation decision generally these models assume that individuals decide whether or not to accept employment by comparing offered hours with desired hours if desired hours exceed offered hours then the individual enters the labor force models with a fixed hour constraint represent an improvement but they ignore the possibility that a large proportion of the labor force is likely to be either underemployed or overemployed due to the ubiquity of fixed hour employment the presence of these types of jobs is well documented in the literature schor 1991 lists several reasons including lack of lower skilled jobs costly fringe benefits and increased business competition why underemployment and overemployment is prevalent in the u s workplace prior studies by mossin and bronfenbrenner 1967 and by altonji and paxson 1988 document underemployment in the workplace in a study of the u s work force ham 1982 found that unemployed and underemployed workers ranged from 19 2 in 1973 to 28 2 in 1970 1 on the overemployment side tarling 1987 claims that recent evidence indicates that many employees would be prepared to forgo some of their earnings in order to reduce their hours of work p 85 bockstael et al 1987 make a simi lar observation noting that in their sample individuals with fixed working hours appear to value time much more highly than the wage rate and would be willing to trade work for leisure p 301 hahnel 1998 concluded that results from a 1994 survey suggest that u s workers have a slight preference for pay cuts in order to reduce their work hours about 50 of the respondents claimed they would accept a 10 reduction in pay in order to work a four day week well over half of the respondents in the survey claimed that it was either fairly difficult or almost impossible to reduce their work hours and over 60 reported that reducing their work hours would have a negative impact on their careers although the existence of underemployment and overemployment is well documented explicitly accounting for it in labor supply models remains largely unexplored in the literature in this paper the labor supply model originally analyzed by heckman 1974 is extended to recognize and incorporate fixed hour situations heckman s model which has been described as the most prevalent in the literature by zabel 1993 is derived by comparing reservation and market wages in its original form it posited a strong link between the labor force participation decision and the labor supply decision

do wage cuts damage work morale evidence from a natural field experiment employment contracts are often incomplete leaving many responsibilities subject to workers discretion high work morale is therefore essential for sustaining voluntary cooperation and high productivity in firms we conducted a field experiment to test whether workers reciprocate wage cuts and raises with low or high work productivity wage cuts had a detrimental and persistent impact on productivity reducing average output by more than 20 percent an equivalent wage increase however did not result in any productivity gains the results from an additional control experiment with high monetary performance incentives demonstrate that workers could still produce substantially more output leaving enough room for positive reactions altogether these results provide evidence consistent with a model of reciprocity as opposed to inequality aversion

fairness and frictions the impact of unequal raises on quit behavior we analyze how separations responded to arbitrary differences in own and peer wages at a large us retailer regression discontinuity estimates imply large causal effects of own wages on separations and on quits in particular however this own wage response could reflect comparisons either to market wages or to peer wages estimates using peer wage discontinuities show large peer wage effects and imply the own wage separation response mostly reflects peer comparisons the peer effect is driven by comparisons with higher paid peers suggesting concerns about fairness separations appear fairly insensitive when raises are similar across peers suggesting search frictions and monopsony are relevant in this low wage sector

the effects of progressive taxation on labor supply when hours and wages are jointly determined this paper extends a standard intertemporal labor supply model to account for progressive taxation as well as the joint determination of hourly wages and hours worked we show that these two factors can have implications for both estimating labor supply elasticities as well as for using these elasticities in tax analysis failure to account for wage hours ties and progressive taxation may cause the hours response to marginal tax rate changes to be understated by 5 to 30 percent for men

the effect of taxation on labor supply when on the job amenities are endogenous abstract in a labor supply model where on the job amenities are endogenous the tax on earnings affects both the net price of leisure and the net price of amenities contrary to the traditional model of labor supply the compensated tax effect on desired work hours in this case is not necessarily negative

individual preferences monetary gambles and stock market participation a case for narrow framing we argue that narrow framing whereby an agent who is offered a new gamble evaluates that gamble in isolation may be a more important feature of decision making than previously realized our starting point is the evidence that people are often averse to a small independent gamble even when the gamble is actuarially favorable we find that a surprisingly wide range of utility functions including many nonexpected utility specifications have trouble explaining this evidence but that this difficulty can be overcome by allowing for narrow framing our analysis makes predictions as to what kinds of preferences can most easily address the stock market participation puzzle

selectivity and distributional assumptions in static labor supply models the technique of estimating labor supply models has drastically changed since the early 1970s while early studies 28 23 estimated a single labor supply equation the occurrence of nonworkers soon became an issue of concern that complicated both the model estimated and the estimation technique people choose to work or not to work based on their opportunity set workers are therefore special they have poorer than average alternatives or better than average wage offers 15 the sample of workers is not random anymore but rather self selected ols estimators are biased and inconsistent and new estimation techniques are needed to correct that deficiency this realization led to an expansion of the labor supply model with a wage equation as wage offers of non workers are generally unobservable 9 while at the same time an array of new econometric techniques came forth to deal with problems of self selection and dichotomous endogenous variables two step and maximum likelihood are standard estimation methods nowadays stimulated by work of heckman and others 18 19 in turn these improved techniques allowed for more sophisticated labor supply models involving tax and transfer schedules 8 cost of labor force entry and institutional constraints 12 16 29 and wage rates interactively determined by labor hours 30 all of these new studies have one assumption in common the random disturbances are assumed to be generated by the normal distribution in an appeal to the familiar central limit theorem this theorem states roughly that the combined influence of numerous independent neglected factors may be represented by a single disturbance term that is approximately normally distributed

part time status and hourly earnings of black and white men labor economists now believe that wages and hours are jointly determined creating a premium in the hourly pay of full time workers the size and nature of this premium however varies considerably by race it is shown here that full time work carries a far lower premium for black workers than for white workers and has very different implications for blacks occupational status

migration when social preferences are ordinal steady state population distribution and social welfare this paper adds three dimensions to the received literature it models migration when the individuals preferences regarding their relative incomes are ordinal it works out the resulting spatial steady state distribution of the individuals and it shows that the aggregate of the individuals migration choices in the spatial steady state distribution sums to the social optimum this finding does not apply when the individuals preferences regarding their relative incomes are cardinal we highlight the importance of the assumption about the nature of the individuals social preferences whether ordinal or cardinal to studying and predicting their migration behaviour and to elucidating the consequences of that behaviour for social welfare

job changes and hours changes understanding the path of labor supply adjustment we use british panel data to investigate single women s labor supply changes in response to three reforms that affected individuals work incentives we use these reforms to identify changes in labor supply there is evidence of small hours of work effects for two of such reforms a third reform in 1999 instead led to a significant increase in single mothers hours of work the mechanism by which the labor supply adjustments were made occurred largely through job changes rather than hours changes with the same employer this is little overall effect of the reforms on wages

individual and aggregate labor supply in heterogeneous agent economies with intensive and extensive margins we develop a heterogeneous agent general equilibrium model that incorporates both intensive and extensive margins of labor supply a nonconvexity in the mapping between time devoted to work and labor services distinguishes between extensive and intensive margins we consider calibrated versions of this model that dier in the value of a key preference parameter for labor supply and the extent of heterogeneity the model is able to capture the salient features of the empirical distribution of hours worked including how individuals transit within this distribution we then study how the various specications inuence labor supply responses to aggregate technology shocks we nd that abstracting from intensive margin adjustment has large eects on the volatility of aggregate hours even if intensive margin uctuates relatively little

the influence of wages and house prices on british interregional migration decisions this paper considers the paradox of a consistent net outflow of people from areas of high job creation and wages over the past 20 years and suggests the explanation that different individuals have different motivations for moving the labour force survey indicates that workers moving for job reasons have migrated to areas of low unemployment and high nominal wages however the inflow into such areas has been more than compensated for by an outflow of people moving for non job reasons a logit analysis of destination choice indicates that job movers are attracted to areas with high wages but are not affected by high house prices in such areas in contrast active non job movers are deterred from areas of high house prices regional house price differences do not influence the destination choice of homemakers or the terminally sick but they do influence the destination choice of retirees all groups prefer to travel the least distance when moving

how is the worker s weekly hour related to wage over the life cycle the u s evidence abstractthe current study estimates the relationship between weekly hours and weekly wage over the life cycle of a representative sample of workers recognizing the endogeneity of these two variables the study estimates both equations in a simultaneous equations framework and demonstrates that the relationship between weekly hours and weekly wage is not uniform over the worker s life cycle these two variables are negatively related when the workers are young and have a positive relationship when they are matured adults this conclusion remains valid for both men and women our robustness check further confirms that workers respond to wage increases differently at different stages of their working career this has interesting policy implications any policy to influence the worker s hours decision through wage incentive must consider the stage of his her working career

whose preferences are revealed in hours of work it has become orthodox in economics research to interpret the association between hourly earnings and working hours as the expression of the preferences of workers this convention originated in h gregg lewis explanation for the decline in hours of work since the nineteenth century his explanation rested on an explicit resolution of the identification problem inherent in any quantity hours price wage relation for over 40 years researchers have neglected this identification problem with the result that the findings in the purported labor supply literature are of questionable value jel j22 j23 c13

nonconvexities retirement and the elasticity of labor supply abstract we consider two life cycle models of labor supply that use nonconvexities to generate retirement in each case we derive a link between hours worked prior to retirement the intertemporal elasticity of substitution for labor ies and the size of the nonconvexities this link is robust to allowing for credit constraints and human capital accumulation by younger workers and suggests values for the ies that are 75 or higher jel d91 j22 j24 j26

social security and cross country differences in hours a general equilibrium analysis abstract i develop a general equilibrium life cycle model with an intensive and extensive margin of labor supply and endogenous human capital accumulation i use the model to assess the effects of changes to various features of social security on labor supply outcomes of particular interest are changes to the scale of the program and to the relevant eligibility rules i find that the cross country differences in social security programs account for at least 79 of the differences in employment rates of people aged 55 64 and 17 31 of the differences in aggregate hours worked between the us and continental europe

the econometrics of piecewise linear budget constraints a survey and exposition of the maximum likelihood method in this article maximum likelihood techniques for estimating consumer demand functions when budget constraints are piecewise linear are exposited and surveyed consumer demand functions are formally derived under such constraints and it is shown that the functions are themselves nonlinear as a result the econometric problems in estimating such functions are exposited and the importance of the stochastic specification is stressed in particular the specification of both unobserved heterogeneity of preferences and measurement error econometric issues in estimation and testing are discussed and the results of the studies that have been conducted to date are surveyed

the demand for hours of labor direct evidence from california california s longstanding requirement that most women receive time and a half pay for workhours beyond eight in one day was extended to men in 1980 analyzing current population survey data from 1973 1985 and 1991 we find that this overtime penalty substantially reduced the amount of daily overtime worked by california men relative to men in other states comparisons that use women to control for california specific shocks show even stronger effects the estimates imply a price elasticity of demand for overtime hours of at least 20 5

female labor supply with a discontinuous nonconvex budget constraint incorporation of a part time full time wage differential this paper incorporates the well documented part time full time wage differential into an empirical labor supply model with both a heterogeneity and a random error term and estimates that model fo

structural models of family labor supply a discrete choice approach a static neoclassical structural model is presented explaining labor supply of both spouses in two adult households in the netherlands family preferences are described with a direct translog utility function with the husbands leisure the wifes leisure and family income as its arguments we assume that the choice set of each family is finite account is taken of the dutch tax and benefits system we allow for hours restrictions and random preferences and account for unobserved wages of nonworkers the models are estimated using smooth simulated maximum likelihood results based upon dutch cross section data from 1987 are illustrated by confidence intervals for elasticities and by several policy simulations excerpt

the food stamp participation and labor supply of married couples an empirical analysis of joint decisions this paper examines the effect of the food stamp program on intrafamily labor supply and program participation decisions married couples simultaneously choose the labor supply of the husband and wife and whether to participate in the food stamp program using data from the survey of income and program participation the author estimates a nested multinomial logit model simulations indicate smaller labor supply effects to changes in the food stamp benefit than the previous research which focused on single parents married couple program participation is found to be relatively responsive to changes in food stamp benefits

labor supply and taxation in france this paper provides sequential labor supply estimates for french married men and women under specifications analogous to those used by hausman to account for the effects of taxation upon the budget constraint results suggest that even though labor force participation follows the expected pattern work hours are quite rigid most of the variation in the latter being attributed to measurement errors the second part of the paper concentrates on the simultaneous estimation of male and female labor supply conditional maximum likelihood techniques are shown to permit the separate estimation of work hours for both spouses with an appropriate set of instruments aimed at correcting for the biases arising from simultaneity selectivity and the nonlinearity of the budget constraint although consistent the resulting estimates apparently contradict the usual rationality restrictions on family labor supply behavior and seem to confirm the lack of flexibility in work hours

canadian jobs and firm size do smaller firms pay less even after controlling for observable workers characteristics and for occupation and industry specific effects a substantial wage differential remains between large and small firms what underlies the remaining wage differential is unclear direct evidence on pension plan coverage and on lay off rates by firm size is inconsistent with the bad working conditions hypothesis the union avoidance hypothesis does not seem to explain an important portion o f the wage differential as suggested by efficiency wage models part of the remaining wage differential may be due to firms heterogeneity similarly perhaps large firms pay higher wages simply partly beca use they employ workers with more unobserved abilities because differen t explanations of the wage differential may lead to different policy implications determining the source of the wage firm size effect is an important question for future research

the many faces of human sociality uncovering the distribution and stability of social preferences there is vast heterogeneity in the human willingness to weigh others interests in decision making this heterogeneity concerns the motivational intricacies as well as the strength of other regarding behaviors and raises the question how one can parsimoniously model and characterize heterogeneity across several dimensions of social preferences while still being able to predict behavior over time and across situations we tackle this task with an experiment and a structural model of preferences that allows us to simultaneously estimate outcome based and reciprocity based social preferences we find that non selfish preferences are the rule rather than the exception neither at the level of the representative agent nor when we allow for several preference types do purely selfish types emerge instead three temporally stable and qualitatively different other regarding types emerge endogenously i e without pre specifying assumptions about the characteristics of types when ahead all three types value others payoffs significantly more than when behind the first type which we denote as strongly altruistic type is characterized by a relatively large weight on others payoffs even when behind and moderate levels of reciprocity the second type denoted as moderately altruistic type also puts positive weight on others payoff yet at a considerable lower level and displays no positive reciprocity while the third type is behindness averse i e puts a large negative weight on others payoffs when behind and behaves selfishly otherwise we also find that there is an unambiguous and temporally stable assignment of individuals to types moreover the three type model substantially improves the out of sample predictions of individuals behavior across additional games while the information contained in subject specific parameter estimates leads to no or only minor additional predictive power this suggests that a parsimonious model with three types captures the bulk of the predictive power contained in the preference estimates

the determination of wages employment and work hours in an economy with centralised wage setting sweden 1950 83 a key component of recent explanations for the growth in unemployme nt in western europe is a negative relation between wage rates and employment this paper examines the evidence for such a relationship for swedish manufacturing industry and also investigates the corresponding movements of hours of work the findings form the ingredients of a structural model of the labor market which is estimated using time series observations from 1951 t o 1983 the greater volatility of employment relative to earnings is measured by a specific parameter which in this model relates to the objectives of trade unions copyright 1988 by royal economic society

why not cut pay abstract i interviewed over 300 business people labor leaders business consultants and counselors of unemployed people all in the northeast of the united states during the recession of the early 1990 s in order to learn why wages and salaries declined in only a few firms employers were reluctant to cut pay because they believed doing so would hurt employee morale leading to lower productivity and current or future difficulties with hiring and retention it was thought that these effects would in the end cost more than the savings from lower pay there were few indications that unemployed people had excessive wage expectations on the contrary many unemployed were too flexible and found themselves rejected by firms as overqualified in most companies pay cuts were not a useful alternative to layoffs because pay cuts would not make it worthwhile to retain many employees and because layoffs harmed morale less than would pay cuts the findings support none of the theories of wage rigidity except those of solow and akerlof that emphasize morale

disentangling the effect of arthritis on earnings a simultaneous estimate of wage rates and hours worked poor health affects both wage rates and hours of work here we develop a procedure for examining the separate impact of a specific chronic disease arthritis on wages and hours worked and then translate these results into earnings our methodology provides a consistent approach for measuring how a specific chronic disease affects total earnings as well as its component parts we find that arthritis affects wage rates and hours worked differently and the pattern of these effects differs considerably between men and women

technology utilization and inflation what drives the new keynesian phillips curve we argue that the new keynesian phillips curve literature has failed to deliver a convincing measure of real marginal costs we start from a careful modeling of optimal price setting allowing for nonunitary factor substitution nonneutral technical change and time varying factor utilization rates this ensures the resulting real marginal cost measures match volatility reductions and level changes witnessed in many u s time series the cost measure comprises conventional countercyclical cost elements plus procyclical and covarying utilization rates although procyclical elements seem to dominate the components of real marginal cost components are becoming less cyclical over time incorporating this richer driving variable produces more plausible price stickiness estimates than otherwise and suggests a more balanced weight of backward and forward looking inflation expectations than commonly found our results challenge existing views of inflation determinants and have important implications for modeling inflation in new keynesian models

labor supply as a choice among latent jobs unobserved heterogeneity and identification this paper discusses aspects of a framework for modeling labor supply where the notion of job choice is fundamental in this framework workers are assumed to have preferences over latent job opportunities belonging to worker specific choice sets from which they choose their preferred job the observed hours of work and wage is interpreted as the job specific hours and wage of the chosen job the main contribution of this paper is an analysis of the identification problem of this framework under various conditions when conventional cross section micro data are applied

the probability of receiving benefits at different hours of work this study finds that in probit equations 50 of people working 35 hours per week in the us will not be offered benefits or health insurance through their employers to replace services received while on welfare women with an average of 39 hours of work per week have an average 76 probability of being offered medical benefits as one of three example options while men working an average of 43 hours per week have on average a 72 probability of being offered medical benefits the probability of being offered medical insurance life insurance and retirement benefits is slightly over 20 for working 35 hours per week although women have a slightly higher probability of being offered all the benefits individuals with children have a lower probability of being offered all the benefits which is not significant for medical insurance retirement or flexible work schedules individuals working for large firms have a greater probability of being offered benefits excluding flexible scheduling and profit sharing working longer hours increases the probability of receiving benefits except in training situations higher wages are found in the three stage least squares estimation in reduced form equation to be related to more work experience higher aptitude test scores residence in a standard metropolitan statistical area work at larger firms more work hours per week and not being single data are obtained from the 1991 us national longitudinal survey of labor market experience of youth among 1988 persons 26 34 years old who worked and were paid an hourly wage persons in the sample earned an average of 9 00 per hour and worked slightly more than 41 hours per week 33 were black 20 hispanic and slightly under 50 were female about 60 had a child under 6 years old the average firm size was 5205 employees

the newly industrializing countries in the international system explanations of the growth of the newly industrializing countries nics by neoclassical economists and dependency theorists neglect the role of politics in shaping development strategies different social configurations state structures and ideas about development help explain the divergent policy choices made by the export oriented east asian nics korea and taiwan and the more inward looking countries of latin america particularly mexico and brazil these different strategic choices in turn account for variations in the patterns of external dependency that characterize countries in the two regions

market culture and authority a comparative analysis of management and organization in the far east three frameworks purport to explain industrial arrangements and practices a market approach that emphasizes economic characteristics a cultural approach that sees organization as the expression of patterned values and an authority approach that explains organization as a historically developed structure of domination the efficacy of each approach is tested in explaining the organizational structures of three rapidly growing east asian economies japan south korea and taiwan the paper argues through comparative analysis that organizational growth is best explained by market and cultural factors but that authority patterns and legitimation strategies best explain organizational structure

the boundaries of the firm revisited why do firms exist what is their function and what determines their scope these remain the central questions in the economics of organization they are also central questions for business executives and corporate strategists the worldwide volume of corporate mergers and acquisitions exceeded 1 6 trillion in 1997 it is hard to imagine that so much time effort and investment bankers fees would be spent on adjusting firm boundaries unless there was some underlying economic gain indeed the exceptional levels of merger and acquisition activity over the past two decades are a strong indication that economically significant forces do determine organizational boundaries the study of firm boundaries originated with the famous essay by coase 1937 who raised the question of why we observe so much economic activity inside formal organizations if as economists commonly argue markets are such powerful and effective mechanisms for allocating scarce resources coase s answer was in terms of the costs of transacting in a world of imperfect information when the transaction costs of market exchange are high it may be less costly to coordinate production through a formal organization than through a market in large part thanks to the work of williamson 1975 1985 recent decades have seen a resurgence of interest in coase s fundamental insight that firm boundaries can be explained by efficiency considerations our understanding of firm boundaries has been sharpened by identifying more precisely the nature and sources of transaction costs in different circumstances in the process the focus of

an east asian model of economic development japan taiwan and south korea the east asian model of economic development focuses on 5 shared characteristics that seem significant in the contemporary economic development of japan taiwan and korea they are economic characteristics and include 1 high investment ratios 2 small public sectors 3 competitive labor markets 4 export expansion and 5 government intervention in the economy large and efficient investments in human capital and well developed capacities to absorb new technology are 2 other economic features shared by the three one could add overcrowding high man land ratios and scarcity of natural resources though these are handicaps rather than sources of economic strength it is possible however that virtue springs from necessity and that ample arable land or abundant natural resources mainly permit governments to postpone the difficult decisions needed to promote development rather than provide the wherewithal needed to finance development other noneconomic characteristics of the three such as ethnic and linguistic homogeneity relatively compact geography manageable population size and the confucian tradition have not been considered in the model even though they have undoubtedly influenced labor productivity savings behavior and other aspects of economic performance whether the east asian model ought to be followed depends on whether current and foreseeable circumstances are sufficiently like those faced by the three to justify using the same policies that they used applicability of the east asian model should also depend on whether the strategy employed by the three has been responsible for their economic success 2 aspects of the east asian models policy features are noteworthy 1 the policies typically work by influencing rather than replacing private market decisions and 2 the public expects government to intervene to influence economic growth

narrow bracketing and dominated choices an experiment by tversky and kahneman 1981 illustrates that people s tendency to evaluate risky decisions separately can lead them to choose combinations of choices that are first order stochastically dominated by other available combinations we investigate the generality of this effect both theoretically and experimentally we show that for any decisionmaker who does not have constant absolute risk averse preferences and who evaluates her decisions one by one there exists a simple pair of independent binary decisions where the decisionmaker will make a dominated combination of choices we also characterize as a function of a person s preferences the amount of money that she can lose due to a single mistake of this kind the theory is accompanied by both a real stakes laboratory experiment and a large sample survey from the general u s population replicating tversky and kahneman s original experiment where decisionmakers with prototypical prospect theory preferences will choose a dominated combination we find that 28 of the participants do so in the survey we ask the respondents about several hypothetical large stakes choices and find higher proportions of dominated choice combinations a statistical model that estimates preferences from the survey results is best fit by assuming people have utility functions that are close to prospect theory value functions and that about 83 of people bracket narrowly none of these results varies strongly with the personal characteristics of participants we also demonstrate directly that dominated choices are driven by narrow bracketing when we eliminate the possibility of narrow bracketing by using a combined presentation of the decisions the dominated choices are eliminated in the laboratory experiment and are greatly reduced in the survey

social comparison and performance experimental evidence on the fair wage effort hypothesis we investigate the impact of wage comparisons for worker productivity we present three studies which all use three person gift exchange experiments consistent with akerlof and yellen s 1990 fair wage effort hypothesis we find that disadvantageous wage discrimination leads to lower efforts while advantageous wage discrimination does not increase efforts on average two studies allow us to measure wage comparison effects at the individual level we observe strongly heterogeneous wage comparison effects we also find that reactions to wage discrimination can be attributed to the underlying intentions of discrimination rather than to payoff consequences

gift exchange in the workplace addressing the conflicting evidence with a careful test tests of gift exchange wherein agents receive excess wages which are noncontingent on performance in one shot settings have yielded contradictory evidence they sometimes find effort boosts consistent with gift exchange whereas they sometimes find no effort increases consistent with a standard model we identify eight confounds that could have led to the mixed evidence agent disutility from being viewed as selfish small samples insufficient wage raises an effort ceiling fatigue selection of abler workers reemployment concerns and peer effects and run a comprehensive test addressing them our test consisted of a field experiment hiring workers for a data entry job followed by laboratory games assessing their prosocial behavior after addressing these confounds we find that behavior during the field test was consistent with a standard model workers did not repay fixed wage raises with an effort boost but they did raise effort in response to a piece rate the piece rate scheme was also more e

working hours and hedonic wages in the market equilibrium in the conventional model of labor supply working hours are implicitly assumed to be divisible goods which is an obviously unrealistic assumption the purpose of this paper is to analyze working hours as indivisible goods when working hours are indivisible labors are differentiated in the market by their length and wages will be a function of working hours the main conclusions are that 1 in the market equilibrium the elasticity of the hedo nic wage curve with respect to hourly wage rates must be positive or less than a1 and 2 generally data will reveal neither demand nor su pply structures copyright 1987 by university of chicago press

labor supply preferences hours constraints and hours wage tradeoffs in a labor market with tied hours wage packages and wage dispersion for a particular type of job constrained workers may be willing to sacrifice wage gains for better hours when changing jobs likewise workers may accept jobs offering undesirable hours only if the associated wage gains are large we investigate this issue empirically by examining whether overemployment and underemployment on the initial and new job affects the relation between hours changes and wage changes for quitters our results generally support the view that an individual requires compensation to work in a job that given the individual s particular preferences offers unattractive hours

impact of internal migration on labor market outcomes of native males in thailand abstractwe investigate the impact of internal migration on local labor markets in thailand using an instrumental variables approach based on weather and distance we construct an exogenous measure of the net migration inflow into each region our econometric results show that instrumenting for the possible endogeneity of net inward migration is crucial to the analysis the results suggest substantial adjustments in hours worked and weekly wages in response to short term changes in labor supply for low skilled males

housing subsidies and work incentives in great britain in great britain the move away from rented accommodation to owner occupation is leaving behind a large group of households with low incomes wages and hours of work and high housing costs who are increasingly in receipt of welfare transfers the disparity along all of these dimensions between renters and owner occupiers has continued to grow since the 1970 s the relationship between housing costs wages and transfer programmes is complex and yet plays an important part in determining the incentive to work for individuals in low income or high housing cost households while it is true that many individuals who are in these categories are out of the labour force retired sick and disabled there are many who are not and whose incentive to seek work or to work harder if already in work could be modified by directly changing the rent levels they face or indirectly via changes to the structure of programmes designed to subsidise housing for the poor here we estimate a static discrete choice labour supply model which allows for housing benefit programme participation we use samples of 42491 married women and 13340 unmarried women drawn from great britain family resources surveys 1994 5 97 8 we find that women are quite responsive to labour supply incentives housing benefit income has similar incentive effects to earned income which suggests any stigma is small our analysis is complemented by simulating housing benefit and direct rent subsidy reforms

equilibrium search and tax credit reform an empirical equilibrium job search model with wage posting is developed to analyze the labor market impact of uk tax reforms the model allows for a rich characterization of the labor market with hours responses accurate representations of the tax and transfer system and both worker and firm heterogeneity the model is estimated with pre reform longitudinal survey data using a semi parametric estimation technique and the impact of actual tax reform policies is simulated the model predicts that the british working families tax credit and contemporaneous reforms increased employment with equilibrium effects found to play a relatively minor role

world economy level development and income distribution an integration of different approaches to the explanation of income inequality abstract the paper briefly outlines explanations of international differences in personal income distribution that have been formulated within the world economy and the level of development paradigm the predictive power of the central variables of the paradigms are tested in a cross national regression analysis with 72 countries the regression results suggest support for hypotheses from both paradigms but also suggest a partial integration of theoretical elements from both paradigms the outcome of the proposed theoretical integration offers a new interpretation of the well known curvilinear relationship between level of development and income inequality this new view on the curvature of the relationship expects the integration into the world economy to result in increased income inequality in peripheral countries but different from other views it is not implied that inequality is substantially reduced in development the core and periphery position of countries in the world economy is seen to stabilize income inequality differences between these groups of countries under these circumstances developing countries generally cannot be expected to reduce substantially their income inequality in the course of economic growth

interpreting labor supply regressions in a model of full and part time work we construct a family model of labor supply that features adjustment along both the intensive and extensive margin intensive margin adjsutment is restricted to two values full time work and part time work using simulated data from the steady state of the calibrated model we examine whether standard labor supply regressions can uncover the true value of the intertemporal elasticity of labor supply parameter we find positive estimated elasticities that are larger for women and that are highly significant but they bear virtually no relationship to the underlying preference parameters

does transparency lead to pay compression this paper asks whether pay disclosure in the public sector changes wage setting at the top of the distribution i examine a 2010 california mandate that required municipal salaries to be posted online among top managers disclosure led to approximately 7 percent average compensation declines and a 75 percent increase in their quit rate relative to managers in cities that had already disclosed salaries the wage cuts were largely nominal wage cuts were larger in cities with higher initial compensation but not in cities where compensation was initially out of line with measured fundamentals the response is more consistent with public aversion to high compensation than the effects of increased accountability

reciprocity under brief and long time delays we report the results from three experiments embedded in the same overarching design which extends the gift exchange paradigm for the study of worker employer relationships we focus on the effect of the length of the delay between the time at which workers learn their wage and when they choose an effort level on the relationship between wage and effort we compare effort choices made within a few hours with those made several weeks afterward we find that the strength of the wage effort relationship decreases over time and this change appears to be driven by workers who receive low wages jel c91 j33 m52

working long hours and early career outcomes in the high end labor market this study establishes empirically a positive but nonlinear relationship between weekly hours and hourly wage growth for workers who put in over 47 hours per week 5 extra hours are associated with a 1 increase in annual wage growth this correlation is not present when hours are lower the relationship is especially strong for young professionals data on promotions provide evidence in support of a job ladder model that combines higher skill sensitivity of output in higher level jobs with heterogeneous preferences for leisure the results can be used to account for part of the gender wage gap

labour supply the roles of human capital and the extensive margin we specify and estimate a life cycle labour supply model that expands on earlier work by simultaneously including human capital accumulation saving and bequests an active extensive margin a realistic specification of the progressive tax structure and the social security system and an accounting for private pensions and health expenditures by incorporating all these features we develop new insights into how taxes affect life cycle labour supply for instance we find that labour supply elasticities vary in important ways with age education and the tax structure itself we also show how human capital affects elasticities differently on the intensive versus extensive margins

nonwage benefits in a simultaneous model of wages and hours labor supply functions of young females this article argues that the negative relationship between weekly hours worked and the gross hourly wage rate is due to the provision of fringe benefits as the total weekly wage increases employers and employees avoid taxation by substituting wages with nontaxable nonwage benefits i produce a wage that incorporates the benefit effects and estimate the corresponding labor supply elasticities an estimator is presented for the wage hours market locus and the structural labor supply function an empirical application indicates that an estimated negative labor supply elasticity associated with the observed gross wage is reversed when the adjusted wage is employed

tanzanian formal sector workers participation in informal production a theoretical model is developed explaining formal sector workers participation in the informal sector a reduced form informal sector participation function is derived from a specific utility function a specific informal sector production function and a specific informal sector earnings function the participation function can be estimated consistently and provides a solution to the problem that informal sector wages in developing countries are hard to observe a sample of tanzanian formal sector workers is used to estimate the participation function a majority of tanzanian formal sector workers participate in informal production participation in informal production is inversely related to household income to living in dar es salaam and to being a mother with small children participation is positively related to age and multiple job holding seems to play a very different role in the transition from work to retirement in tanzania compared to industrialized countries
