experience tenure and wage growth of young black and white men this paper studies the source of differences in wage growth between young black and white workers focusing on terminal high school graduates from the national longitudinal survey of youth we estimate the returns to on the job tenure and general labor market experience using ordinary least squares altonji and shakotko and topel estimators results from all three estimators indicate that returns to general experience for black workers trail those for white workers but that black workers earn equal if not higher returns to tenure than do white workers

the quit propensity of married men this paper hypothesizes that the quit propensity of married men rises with an increase in their wives income assuming that individuals are risk averse and that quitting is risky the wife s income increases the husband s expected value of quitting by reducing the variance of expected family income using the longitudinal data from the michigan panel study of income dynamics psid the wife s income is found to have a large effect on quits the average husband s quit rate increases by about 45 when the wife s income rises from zero to two thirds that of the husband s the wife s income effect nearly offsets the negative effect that marriage typically has on male quit rates

changes in earnings instability and job loss this paper examines the contribution of job loss or displacement to increasing male earnings instability between 1970 and 1991 earnings instability increased among both displaced and not displaced men so changes associated with job loss cannot fully explain rising instability changes in the incidence and consequences of job loss did however add substantially to growing earnings instability and to the overall variance of earnings there is evidence that displacement substantially raised earnings volatility for several years after job loss that effect combined with increased numbers of recently displaced workers in the 1980s relative to the previous decade contributed to rising overall earnings instability

the economic consequences of labor mobility unlike most previous research on the relative changes in earnings of job stayers and job changers this study examines the variance in earnings changes rather than simply average changes men and women rather than only men and the five year period following job change rather than only the first year or two the author finds great variability in earnings changes both within and across race and gender groups notably men gained more from quits and except in the case of low wage workers lost less from layoffs than women also men suffered a much smaller penalty than women for repeated job changes for all groups the percentage difference between earnings before and after leaving a job generally persisted for several years

returns to seniority in union and nonunion jobs a new look at the evidence in cross sectional data the positive association between seniority and earnings is typically much stronger for nonunion workers than for union workers a finding that seems inconsistent with the generalization that seniority is more important in the union sector than in the nonunion sector the authors of this paper show that standard estimates of the return to seniority are likely to be biased upward due to unmeasured worker heterogeneity job heterogeneity or both and they argue that this bias is likely to be larger in the nonunion sector than in the union sector when they correct for this problem in analyzing data on male blue collar workers for the years 1968 80 they find a larger return to seniority in the union sector than in the nonunion sector

embracing uncertainty in building energy efficiency policy a case study of a building energy standard abstract quantified goals for reducing energy consumption in buildings play a significant role in national and international energy policy calculations of potential energy savings from different interventions may be unreliable due to various types of uncertainty resulting in a performance gap between predictions and actual energy consumption yet building energy policy continues to rely heavily on apparently robust calculations of energy savings raising the question of why and how the policy process tolerates uncertainty and inaccuracy when quantification is its central logic we describe a case study of the development of a new mandatory building energy standard in which there is a lack of consensus on the energy it would save we found that when this uncertainty was brought to light the policy process raised other unquantified logics in favour of energy efficiency measures using literature on calculation and expertise we discuss how quantification is used in policy making and how uncertainties are repressed enabling the energy performance gap to persist we conclude that broader awareness of the modes in which quantitative and other logics are used in energy policy and a reframing of the types of energy savings to be made may serve policy making better than an illusion of calculative certainty

the costs of worker displacement this study identifies part of the social loss attendant upon displacement as the remaining value of the assets specific to the severed employment relationship a bargaining model is used to link wage tenure profiles to the amount of information firms and workers possess about the duration of that relationship if information is good the profile will flatten as displacement approaches using psid data for workers separated between 1977 and 1981 wage tenure profiles are found not to change this suggests that either workers or both firms and workers are surprised by the displacement the present value of that part of the social loss attributable to the worker s share of firm specific capital is around 7 000 1980 dollars

trends in job instability and wages for young adult men data and measurement problems have complicated the debate over trends in job instability in the united states we compare two cohorts of young white men from the national longitudinal surveys nls construct a rigorous measure of job change and confirm earlier findings of a significant increase in job instability we then benchmark the nls against other main data sets in the field and conduct a thorough attrition analysis extending the analysis to wages we find that the wage returns to job changing have both declined and become more unequal for young adults mirroring trends in their long term wage growth

a theory of career mobility this paper analyzes theoretically and empirically the role and significance of occupational mobility in the labor market focusing on individuals careers it provides additional dimensions to the analysis of investment in human capital wage differences across individuals and the relationships among promotions quits and interfirm occupational mobility it is shown that part of the returns to education is in the form of higher probabilities of occupational upgrading within or across firms given an origin occupation schooling increases the likelihood of occupational upgrading furthermore workers who are not promoted despite a high probability of promotion are more likely to quit

a theory of quits and layoffs with efficient turnover this paper answers the efficient turnover literature s long silence regarding the quit layoff distinction treating quits as worker initiated separations and layoffs as firm initiated separations i establish that the existence of layoffs is compatible with optimizing workers and firms forming and dissolving employment matches to exploit all the gains from trade the efficient turnover approach is shown to be consistent with many empirical regularities that distinguish quits from layoffs structural implications of the model are tested on data from the psid

job duration over the business cycle evidence from the national longitudinal survey of youth nlsy suggests that the cyclicality of job duration depends on the worker s prior and future employment status for example among matches formed with previously nonemployed workers those that end with the worker returning to nonemployment display procyclical duration in contrast matches that end because the worker switches to another job have countercyclical duration moreover differences in starting wages do not account for these patterns

interpreting panel data on job tenure tenure responses in the panel study of income dynamics psid and the national longitudinal surveys are often inconsistent with calendar time these inconsistencies pose special problems in the psid because job changes cannot be identified directly so researchers must infer them from error ridden tenure data we use alternative rules for partitioning psid data into jobs and then estimate several wage and mobility models to assess the sensitivity of parameter estimates to the partitioning method we also assess the importance of replacing raw tenure data with imputed measures that are internally consistent

the dynamics of dual job holding and job mobility this article concerns dual job holding and its link to job mobility we present evidence from u s data on patterns of dual job holding hours changes and job mobility we find that workers move into and out of second jobs frequently that these movements are associated with large changes in work hours and that hours constraints may prompt workers to take second jobs second we review theories of dual job holding and present a stochastic dynamic model of dual job holding and job mobility in which decisions to take second jobs and or change main jobs are made simultaneously

a path dependent approach to security valuation with application to interest rate contingent claims abstract the last two decades have witnessed a tremendous growth in the volume of assets and liabilities whose cash flows depend in a variety of ways on the path of interest rates some of these including floating rate notes and swap agreements contractually base cash flows on current and past interest rates and contain caps floors and other more complex features others including mortgages many corporate bonds and time deposits are fixed rate instruments that contain embedded options such as those to prepay call or withdrawal the irregular exercise of these options causes cash flows to vary as time proceeds and interest rates rise or fall this paper develops a state contingent claims technique for valuing such securities it is derived from the option based model of breeden and litzenberger 1978 using the transition matrix approach of banz and miller 1978 particular attention is paid to valuing so called path dependent securities whose contemporaneous cash flows depend on the historical path of interest rates as well as their current level a detailed example is provided in which an adjustable rate mortgage is valued under a variety of economic and security specific assumptions

is job stability in the us falling reconciling trends in the current population survey and panel study of income dynamics this article considers whether two commonly used sources of information on employer tenure the panel study of income dynamics and the current population survey yield systematically different trends in employer tenure little evidence of a discrepancy between the data sets in the 1980s or 1990s is found when comparable samples variable definitions and time frames are used neither data set shows a significant trend in the share of workers with 1 year or less of tenure while both data sets show an increase in the fraction of men with less than 10 years of tenure starting in the late 1980s

do wages rise with job seniority many previous studies have found a strong positive effect of job seniority tenure on wages this paper re examines the evidence using a simple instrumental variables scheme to deal with the fact that tenure is likely to be related to unobserved individual and job characteristics that affect the wage we use the variation of tenure over a given job match as the principal instrumental variable for tenure the variation in tenure over the job is uncorrelated by construction with the fixed individual and job match specific components of the error term of the wage equation our main finding is that the partial effect of tenure on wages is small and that general labour market experience and job shopping account for most wage growth over a career the strong cross section relationship between tenure and wages is due primarily to heterogeneity bias prior researchers see mincer and jovanovic 1981 bartel and borjas 1981 borjas 1981 cline 1979 and mellow 1981 and many others have established that job seniority has a strong positive relationship with wage rates in a cross section or a cross section time series of individuals in this paper we re evaluate the evidence concerning the partial effects on wages of job seniority tenure and total labour market experience the extent to which wages rise with tenure is important for several reasons first and foremost the wage tenure profile is a fundamental question about the structure of earnings over careers second the wage tenure profile is a key determinant of the extent to which the earnings power of individuals is tied to specific jobs and it is important for assessment of the losses suffered by displaced workers hamermesh 1984 third evidence that wages rise with job tenure has been used to explain the decline in quits with tenure since the wage growth on the current job lowers the probability that the worker will locate a superior alternative a growing theoretical literature surveyed in parsons 1984 has taken the evidence of a strong wage tenure profile at face value and sought to provide an explanation for the relationship the most prominent explanation is the theory of specific human capital oi 1962 becker 1962 mincer 1974 parsons 1972 kuratani 1973 and hashimoto 1980 in which the growth of wages with tenure holding experience constant is attributed to the worker s share of investments in firm specific skills more recently lazear 1981 has presented a supervision model of wage growth in which firms defer compensation as a means of inducing workers not to shirk freeman 1977 and harris and holmstrom 1982 provide an explanation for wage growth based on an insurance motive salop and salop 1976 nickell 1976 and guasch and weiss 1982 present adverse selection models of wage growth in which firms use a wage tenure profile as a

overeducation in the labor market this article examines the reasons for the observed discrepancy between workers actual and required levels of schooling and the resulting differences in returns to schooling overeducated workers are found to be younger and to have lower amounts of on the job training than workers with the required level of schooling they also have higher rates of firm and occupational mobility characterized by movement of higher level occupations the findings suggest that overeducation can be explained by the trade off between schooling and other components of human capital and by the mobility patterns of overeducated workers

performance pay and wage inequality an increasing fraction of jobs in the u s labor market explicitly pay workers for their performance using bonus pay commissions or piece rate contracts using data from the panel study of income dynamics we show that compensation in performance pay jobs is more closely tied to both observed and unobserved productive characteristics of workers than compensation in non performance pay jobs we also find that the return to these productive characteristics increased faster over time in performance pay than in non performance pay jobs we show that this finding is consistent with the view that underlying changes in returns to skill due for instance to technological change induce more firms to offer performance pay contracts and result in more wage inequality among workers who are paid for performance thus performance pay provides a channel through which underlying changes in returns to skill get translated into higher wage inequality we conclude that this channel accounts for 21 of the growth in the variance of male wages between the late 1970s and the early 1990s and for most of the increase in wage inequality above the eightieth percentile over the same period

occupational specificity of human capital we find that returns to occupational tenure are substantial everything else being constant 5 years of occupational tenure are associated with an increase in wages of 12 20 moreover when occupational experience is taken into account tenure with an industry or employer has relatively little importance in accounting for the wage one receives this finding is consistent with human capital being occupation specific

external recruitment and intrafirm mobility i introduction competition for promotion has a very strong effect on employees work incentive in the stereotypic internal labor market described in doeringer and piore 1985 there are only a limited number of ports of entry into a hierarchical firm or organization so that existing employees are insulated to a large extent from external competition in their climb up the corporate ladder however lazear 1992 and baker et al 1994a 1994b find extensive external recruitments at almost all grade levels in their studies of different u s corporations if the boundary between internal and external labor markets is not impervious then the choice between external recruitment and internal promotion in filling openings becomes an important personnel decision with interesting implications on incentives opening up the competition to external applicants discourages collusion among candidates as well as offers a quick channel for absorbing external talents however it also reduces the probability of promotion for existing workers and thus their incentive to exert with adverse effect on the firm s profit in chan 1996 i suggest that work incentive for the internal promotion candidates can be maintained if external competitors are handicapped in the contest such favoritism for existing employees implies that senior positions tend to be filled internally more often than not and that a worker is recruited from the outside only if he or she demonstrates a significant margin of superiority over the internal candidates this is consistent with the observations that external recruits account for only about 15 to 20 of all appointments to top management positions see denis and denis 1995 warner et al 1988 and that roughly the same percentage of chief executive officers ceos of large u s firms are outsiders see agrawal et al 2002 chan 1996 parrino 1997 the handicapping hypothesis of promotion suggests a dilemma in personnel decisions although handicapping external applicants provides incentive for existing employees it also increases the chance of inferior internal contestants being promoted to senior positions where sorting of workers by ability into different particularly senior positions is important efficiency within the organization is compromised this tension between sorting and maintaining work incentive is explored in tsoulouhas et al 2001 unfortunately the gain in realism with the incorporation of sorting is offset by ambiguity in most of the results the ability of the firm to precommit to future compensation the relative abilities of the internal and external contestants the cost of work effort and commonality within the firm and within the industry all have a role in determining the direction and magnitude of the handicap with different combinations of these factors resulting in very different outcomes whether one starts with the chan model or the tsoulouhas model empirical evidence is important to establish the significance of the competitive handicap against external candidates there has been no shortage of empirical investigations of the incentive effects of tournaments most follow one of two different analytic approaches one approach uses cross sectional or nonpanel data such as data on executive salary across firms gibbons and murphy 1990 leonard 1990 main et al 1993 or data from professional sports tournaments see for example ehrenberg 1990 few of these studies address the distinction between internal or external contestants agrawal et al 2002 is an exception it tests implications of the handicapping hypothesis derived in tsoulouhas et al 2001 by analyzing more than 1 000 ceo successions in large u s firms from 1974 to 1995 even though some of the results are also consistent with a traditional human capital interpretation and the key hypothesis can be derived from the tsoulouhas model only under certain conditions they offer some support for the existence and relevance of the competitive handicap against external contestants

racial differences in residential and job mobility evidence concerning the spatial mismatch hypothesis abstract the spatial mismatch hypothesis asserts that job decentralization adversely impacts the labor market outcomes of african americans this paper tests whether race and job access have an independent effect on the probability of a joint residential move and job change no evidence is found to indicate that race directly influences the joint probability the paper finds however that poor job access has an independent negative effect on the probability of a joint residential move and job change because african american residences are heavily concentrated in american central cities these results suggest that african american workers may not be able to fully adjust as new jobs are created in the suburbs

tenure business cycle and the wage setting process abstract we analyze the interaction between job tenure and external labor market conditions in wage determination first we introduce a model that combines job matching with business cycle effects as the employment relationship progresses the worker appropriates a portion of the value of the match specific human capital she accumulates gradually becoming shielded from the cyclical variations in external labor market conditions the employment relationship is progressively internalized then we present empirical evidence supporting this prediction the elasticity of wages to the unemployment rate decreases with tenure this finding is robust to different specifications that allow for job heterogeneity and it contributes to the interpretation of recent evidence of changes in the effect of the business cycle on wages

job finding and separation rates in the oecd abstract we provide a set of comparable estimates of average monthly job finding and separation rates for over 20 oecd countries that can be used for the cross country analysis of labor markets

are workers permanently scarred by job displacements this paper investigates whether workers suffer lasting scars following job displacements using david t ellwood s 1982 terminology scars represent persistent effects whereas blemishes are transitory adjustments which dissipate over time more precisely dislocated individuals are defined as scarred if they continue to earn less or to be unemployed more than their nondisplaced counterparts even after the conclusion of a several year adjustment period
