the wage impact of trade unions in the uk public and private sectors there is a growing gap in the union membership wage premium between public and private sector workers in the united kingdom using the labour force surveys of 1993 2006 the gap between the membership premium in the public and private sectors closes with the addition of three digit occupational controls although significant wage premia remain in both sectors however using the workplace employment relations survey of 2004 the public sector union membership wage premium remains roughly twice the size of the private sector membership premium having accounted for workplace fixed effects and workers occupations job characteristics qualifications and demographics

the excess demand for subsidized child care in germany the extension of publicly provided or subsidized child care is currently one of the priorities of the political agenda in many european countries in this article the excess demand for subsidized child care slots in germany is estimated using a partial observability model the results show that there is considerable excess demand for child care for children aged less than 3 years in east and west germany even among children with working mothers

job changing decisions of faculty members a case study of a model with multiple selection a model of faculty job search behaviour must explain the two decisions of whether to search for another position and of whether to accept the new position if an offer is received developing a theoretical model of this process is not diffcult but estimation difficulties caused by the self selection inherent in the data subsamples of non searchers searchers who stay and searchers who leave must be considered to estimate the structural determinants of these decisions we make assumptions regarding the covariance matrix of the error terms of the structural equations that allow us to use a straightforward extension of earlier approaches to this problem the particular variables that correspond to the theoretical measures in the model are not common to most data bases on faculty thus we were forced to use a rather old data base to estimate the model which reduces the usefulness of the estimates for current policy purposes nonetheless the estimates do shed light on the efficacy of the model and illustra

union wage hours and earnings differentials in the construction industry full information maximum likelihood is used to estimate union wage hours and earnings markups construction union wage markups are positive 58 2 at the sample means since union hours markups are negative 4 0 for most demographic groups union earnings markups 51 1 are smaller than the wage markups all exogenous variables are allowed to interact with the endogenous union dummy variable which allows us to test whether markups vary across demographic groups whether increased local unionization has a positive spillover effect in the nonunion sector and whether increased local unemployment equally affects wages and hours in increased local unemployment equally affects wages and hours in the two sectors

the role of the desire for union status in the decision to enter local government job queues the us evidence following a two stage bivariate probit approach this study estimates local government and union job queues in a simultaneous equations framework by relaxing the restrictive assumption of independence between the worker s queuing and the employer s hiring decisions it overcomes a major limitation of most of the earlier job queue estimates the results indicate that the worker s queuing decision for local government jobs in the united states is determined partly by the desire for unionized employment the converse however is not true seniority with the current employer emerges as a significant determinant of both workers queuing and employers hiring decisions furthermore local governments act as model employers by being more likely to hire minorities and females from the pool of job applicants

the rising skill premium and deunionization abstract during the past 50 years the us economy has seen a rapid decline in labor union membership and a substantial rise in wage inequality since labor unions compress wages between skilled and unskilled workers a rising skill premium encourages skilled workers to withdraw from the union if this withdrawal is accompanied by a fall in the productivity of unskilled workers firms become reluctant to hire the relatively expensive union workers reinforcing the decline in the unionization rate evaluating this hypothesis we find that the rise in the skill premium explains about 40 of the decline in the unionization rate

the effect of unions on the structure of wages a longitudinal analysis this paper studies the effects of unions on the structure of wages using an estimation technique that explicitly accounts for misclassification errors in reported union status and potential correlations between union status and unobserved productivity the econometric model is estimated separately for five skill groups using a large panel data set formed from the u s current population survey the results suggest that unions raise wages more for workers with lower levels of observed skills in addition the patterns of selection bias differ by skill group among workers with lower levels of observed skill unionized workers are positively selected whereas union workers are negatively selected from among those with higher levels of observed skill despite a large and sophisticated literature there is still substantial disagreement over the extent to which differences in the structure of wages between union and nonunion workers represent an effect of trade unions rather than a consequence of the nonrandom selection of unionized workers over the past decade several alternative approaches have been developed to control for unobserved heterogeneity between union and nonunion workers 2 one method that has been successfully applied in other areas of applied microeconometrics is the use of longitudinal data to measure the wage gains or losses of workers who change union status unfortunately longitudinal estimators are highly sensitive to measurement error even a small fraction of misclassified union status changes can lead to significant biases if the true rate of mobility between union and nonunion jobs is low this sensitivity led lewis 1986 to essentially dismiss the longitudinal evidence in his landmark survey of union wage effects in this paper i present some new evidence on the union wage effect based on a longitudinal estimator that explicitly accounts for misclassification errors in reported union status the estimator uses external information on union status misclassification rates along with the reduced form coefficients from a multi variate regression of wages on the observed sequence of union status indicators to isolate the causal effect of unions from any selection biases introduced by a correlation between union status and the permanent component of unobserved wage heterogeneity recognizing that unions may raise wages more or less for

federal and union job queues further evidence from the us labour market recent research on union differentials suggests that although the premium to unionization is higher in the private sector it can hardly be ignored in the federal sector consequently the nature and length of the federal queue may differ between union and non union sectors similarly the union queue may not necessarily be homogeneous between federal and private sectors we estimate separate queues for federal union federal non union and private union jobs from the same sample this avoids the problem of simultaneity between the federal queue and the union queue in addition it explores several important differences that exist between these queues

demand for health insurance and precautionary motives for savings among the elderly abstract this paper examines whether or not the elderly have precautionary motives for savings against uncertain and potentially large medical costs i analyze the relationship between purchases of actuarially unfair health insurance and the individual s ability to self insure in order to create a complete model of this behavior the government programs of medicare and medicaid are also incorporated into the analysis the major results from this paper are that individuals do tend to behave in a manner that is consistent with precautionary behavior and that even among those who do not hold private insurance most act in a manner consistent with their being over insured by medicare

from the fringe to the fore labor unions and employee compensation conventional wisdom suggests that labor unions raise worker wages while the newer empirical literature finds only negligible earnings effects i reconcile this apparent contradiction by arguing th

marginal and conditional probabilities of excess demand abstract this note compares and illustrates two criteria for classifying observations on a non clearing market namely the marginal probability of excess demand and the probability of excess demand conditional on the observed quantity

unionization and the pattern of nonunion wage supplements negotiated standard wage policies reduce dispersion in the log earnings of union members when compared to those of otherwise equal nonunion members 5 6 as large as these dispersion differences are they may underestimate the true influence of union wage policy kahn and curme 14 have suggested that high degrees of unionization actually result in reduced nonunion wage dispersion this follows from a particular model of the union threat effect in which nonunion employers tilt induced wage increases toward low wage workers such tilting makes sense because lower paid workers are assumed to be more likely to support unions ceteris paribus this assumption fails to emphasize that low wage workers may be the least likely to be retained by a newly unionized employer and that this also influences their ultimate decision to support unionization in the face of union avoidance strategies that routinely imply the possibility of job loss low wage employees may recognize that the employer faces greater costs of bringing them up to a standard union wage and thus their chances for retention are lower including this realization results in ambiguous predictions about the influence of unionization on nonunion dispersion not only should the ambiguity of the proper theoretical prediction be highlighted but it should be recognized that the relevant prediction from theoretical models has not yet been tested previous tests are inappropriate because the threat induced wage increases could be tilted toward low wage workers without a necessary reduction in the typical measures of wage dispersion similarly those measures of wage dispersion may actually decline without a general tilt of wages toward low wage workers this possibility exists because of the sensitivity of the usual variance measures to outliers and because of aggregation and endogeneity problems affecting previous methodologies this paper uses 1983 and 1988 current population survey cps data to directly estimate the impact of unionization on the earnings of lowand high wage nonunion workers after controlling for traditional human capital locational and occupational variables unionization increases the log earnings of low wage nonunion workers significantly more than those of high wage nonunion workers this result is found with the very data belman and heywood 2 used to demonstrate that

employment impact of inner city development projects the case of underground atlanta this paper makes use of a unique data set to explore the issue of whether inner city residents are more likely to be hired by a new inner city development than non residents a selection model with partial observability is specified and estimated this partial observability estimates at the hiring stage we determine holding individual and neighbourhood characteristics constant that while inner city residents are less likely to be considered hireable their greater propensity to apply for jobs at this development means that they were at least as likely as non residents to both apply and be hired we also tentatively conclude that distances between an applicant s residence and the location of the development does not appear to have been an issue in the application decision

job queues and the union status of workers this paper develops a model of the determination of the union status of workers that allows for the possibility of queuing for union jobs the empirical results derived using a sample from the university of michigan panel study of income dynamics are supportive of the queuing hypothesis the no queue model can be rejected using a likelihood ratio test this suggests that a simple probit or logit model for union status is misspecified because it is not based on any consistent behavioral theory an important implication of the model is that because most new entrants to the labor market prefer union jobs but cannot get them and because accrual of nonunion seniority makes workers progressively less likely to desire union jobs the union status of workers is largely determined by their success in being selected from the queue early in their working life

nonunion wage rates and the threat of unionization i investigate how the threat of union organization affects the wage paid to nonunion workers i start by outlining the standard model of wage determination by a nonunion employer when faced with the threat of union organization the model suggests that the nonunion wage will be directly related and the union wage gap will be inversely related to the threat i use repeated cross section data from the cps from 1977 2002 to develop a measure of the threat as the predicted probability of union membership i use this measure to estimate earnings functions that use several sources of variation in the likelihood of union membership to identify the threat effect in a manner that reduces the likelihood of omitted variable bias finally i investigate two cases where there has arguably been a change in the likelihood of union organization that is not correlated with changes in the demand for labor these include the wage changes surrounding the introduction of rightto work rtw laws in two states during the period studied and wage changes surrounding deregulation of key industries in the late 1970s and early 1980s the results are mixed the preferred estimates from the analysis using predicted probability of unionization as the threat measure imply very little relationship between either nonunion wages or the union wage gap and the threat the estimates that rely on the introduction of rtw laws show a significant relationship between nonunion wages and the introduction of rtw laws in one of the two states stronger evidence of threat effects is found in the experience of deregulated industries where regulation was a central factor in union strength

models and estimation of disequilibrium for centrally planned economies the planned level of output is an important variable in modelling centrally planned economies and the present paper discusses several disequilibrium models in which the plan level is an endogenous variable a key relationship in such a model is the plan adjustment equation which is the counterpart of the usual priceadjustment equation employed in models of free economies seemingly minor differences in assumptions lead to markedly different econometric models the coherency properties of these are studied and several likelihood functions are derived the most complex of the models includes both endogenous plan levels and endogenous prices

the determinants of workers union status evidence from the national longitudinal surveys using data from the 1980 wave of the young men nls sample this paper provides estimates of the queue model developed by farber to explain the process of union status determination the use of nls data largely avoids the censoring problem encountered by farber in estimating his model and permits direct estimation of crucial probabilities associated with the model despite important differences between econometric methodologies and the data sets analyzed the nls results support farber s conclusion that queueing for vacancies in existing union jobs is an important labor market phenomenon in particular supply constraints on the availability of union jobs are found to dominate worker preferences in explaining differences in extent of unionization by occupation and region but not race

unions and wage inequality in mexico this paper offers empirical evidence on the impact of trade unions on wage inequality in mexico the results indicate that unions were a strongly equalizing force affecting the dispersion of wages in 1984 but were only half as effective at reducing wage inequality in 1996 not only did the unionized percentage of the labor force fall considerably over the period unions also lost some of their ability to reduce wage dispersion among the workers they continued to represent had unions maintained in 1996 the same structural power they possessed in 1984 the rise in wage inequality in the formal sector of the labor market between those years would have been reduced by roughly 11

the effect of imf programs on economic growth abstract using a bivariate dynamic version of the heckman selection model we estimate the effect of participation in international monetary fund imf programs on economic growth we find evidence that governments enter into agreements with the imf under the pressures of a foreign reserves crisis but they also bring in the fund to shield themselves from the political costs of adjustment policies program participation lowers growth rates for as long as countries remain under a program once countries leave the program they grow faster than if they had remained but not faster than they would have without participation

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

hourly earnings in the united states another look at unionization schooling sickness and unemployment using psid data this paper makes use of panel data to consider the effects of unionization schooling sickness and unemployment on individual earnings our results may be summarized as follows the unionization effect is around 15 20 this measure is consistently estimated controlling for both fixed individual attributes and serially uncorrelated measurement error sickness has little immediate impact but there is some indication that after 4 years earnings have fallen permanently by around 8 consequent on a 10 week spell of sickness a spell of unemployment on the other hand leads to a sharp fall in earnings but this effect decays rapidly leaving the possibility of a small permanent impact finally controlling for all fixed individual attributes we are unable to pin down the schooling effect with any accuracy owing to the absence of instruments that are both valid and effective within the data set

tests of the chronic shortage hypothesis the case of poland in the analysis of econometric disequilibrium models it is common to test the n ull hypothesis of equilibrium against the disequilibrium alternat ive this paper tests the null hypothesis of all excess demand tha all observations correspond to positive excess demand against the alternative that permits excess demand of either sign the auth ors use a test due to rogers 1984 which their monte carlo experime nts suggest performs well in small samples as well as a quasi like lihood ratio test which is a suggestive heuristic procedure the da ta are from the aggregate consumption goods market in poland 1955 80 and the paper is thus a test of j kornai s assertion that chroni c shortage characterizes such cpes the results conclusively reject the all excess demand hypothesis for the polish case and the rogers test promises to be of considerable practical use copyright 1988 by mit press

new estimates of union wage effects in the u s abstract we present new estimates for union wage effects using a unique dataset with information on job skill requirements we find the union wage premium to be smaller at higher skill levels consistent with the view that unions work to decrease skill differentials

does high involvement management improve worker wellbeing employees exposed to high involvement management him practices have higher subjective wellbeing fewer accidents but more short absence spells than like employees not exposed to him these results are robust to extensive work wage and sickness absence history controls we highlight the possibility of higher short term absence in the presence of him because it is more demanding than standard production and because multi skilled him workers cover for one another s short absences thus reducing the cost of replacement labour faced by the employer we find direct empirical support for this in accordance with the theoretical framework we find also that long term absences are independent of exposure to him which is consistent with long term absences entailing replacement labour costs and with short absences having a negative effect on longer absences

unemployment insurance job queues and systematic job search an equilibrium approach the labor market effects of unemployment insurance ui have been viewed in several contexts by economists on the one hand the ui system of jobless benefits and experiencerated taxation of firms is seen as influencing firms decisions to lay off workers 9 10 24 2 key in such analyses is the degree to which firms layoffs are subsidized by an imperfect experience rating a tax system in which employers ui taxes increase by less than their workers benefits increase on the other hand many other studies of ui place primary focus on the worker although employer concern for worker well being plays a role even in the work on the impact of ui on firm layoff decisions each of these worker based studies is concerned with one of two issues 1 ui and compensating wage differentials 14 24 or 2 u i and the job search process first hutchens assumes that workers face a choice in the labor market between high wage high layoff probability firms and low wage low layoff probability firms 14 by reducing the cost of being laid off ui increases one s likelihood of choosing the former kind of job along these lines topel finds evidence that ui generosity substitutes for wages and therefore lowers the compensating differential associated with a high layoff job 23 second several authors have studied the effect of ui on job search this work recognizes that ui lowers the cost of searching and therefore raises the reservation wage expected unemployment duration and expected post unemployment wages 2 previous work on the impact of ui on firm layoff decisions has assumed either a layoff subsidy 9 or demand uncertainty 2 in order to generate layoffs and therefore a u i impact on layoffs in contrast to such work this paper views layoffs in an equilibrium context they occur in our model even with no layoff subsidy and or with no demand uncertainty layoffs are of value to the firm in our model since they correspond to workers rejected from a queue of potential trainees from the firm s point of view a queue of applicants may be desirable in order to lower

law of one price in international commodity markets a fractional cointegration analysis the law of one price lop is an important component of most if not all international trade models because this assumption allows researchers to use a single representative price for all regions this paper examines the long run lop for international commodity prices using a generalized notion of cointegration called fractional cointegration this analysis is applied to nine pairs of price series supporting the existence of lop in eight cases

internet start ups access to the bank loan market evidence from italy the analysis of the bank sector s ability to efficiently fuel the birth of new italian business ventures in internet related services is studied in particular through the specification and the estimate of a series of econometric models this paper aims at investigating which characteristics of a large sample of internet start ups and their relative founders facilitate access to the loan market more precisely the role played by founders human capital as a possible significant signal used by banks to evaluate investment projects is addressed estimation results suggest that highly qualified human resources possessed by internet founders do not represent an important driver for gaining access to bank credit and they do not affect the amount of the incurred debt

the demand for labor market structure an economic approach this paper formulates and estimates a model for the determination of employer and union demand for multiemployer vs single employer bargaining units utility maximizing risk averse firms and unions are both assumed to weigh the impact of each type of bargaining unit on the expected level and variability of profits and wages respectively the model is tested on a 1975 sample of 3 486 individual collective bargaining agreements because either party can generally leave a multiemployer unit without the other party s consent a partially observed bivariate probit model is used to estimate demand for structure it is found that the forgone profits due to a multiemployer unit relative to a single firm unit lower firm demands for this type of unit while forgone wages in a multiemployer unit relative to a single firm unit lower union demand for this type of unit

adoption of agricultural innovations as a two stage partial observability process in this paper we reconsider the appropriateness of certain statistical analyses in innovation adoption studies and suggest that partial observability models may sometimes be more useful the proposed models allow for a flexible specification of the process of adoption from one stage to two stages facilitate the modelling of non adopters and remedy the violation of the assumption of full information an application to the adoption of organic cultivation in greece demonstrates the relative merits of the proposed analysis

minimum wages and labor market prospects of women in recent years the field of labor economics has witnessed growth of interest in causes and consequences of female labor force participation principal areas of research include determinants of female wages and labor supply many empirical issues remain unresolved and research continues to focus on the likely ranges of such parameters as the own wage elasticity of hours supplied the cross elasticity with respect to spouse s income the rate of return to female schooling and the issue of self selection in observed earnings of working women one area which remains relatively unexplored is the impact of minimum wage legislation on employment prospects of females the issue of minimum wages is of special interest in the case of women first the proportion of labor force nonparticipation by females exceeds that of males consequently institution of an effective minimum wage plays to a larger audience of nonparticipating females than males it is likely that a significant portion of the positive labor supply response to minimum wages is in the form of previously nonparticipating females second as is well known female wages tend to be lower than those of males owing in part to 1 lower levels of female schooling and experience 2 intermittent life cycle patterns of labor supply and human capital accumulation 3 sorting of females into occupations that are conducive to intermittent behavior and 4 as several researchers suggest gender discrimination consequently women are more likely than men to experience wages that fall short of the legal minimum this study examines the consequences of minimum wages on female employment prospects of special interest is the likelihood of successful job search for women whose wages in the absence of legislation would be below the minimum it is commonly argued that minimum wages in competitive labor markets have the effect of hindering employment prospects of low wage workers this study based on a sample of microdata from the public use sample of the 1980 census proposes a simple framework in which this issue can be addressed in the context of a conventional model of labor supply

working part time by choice or by constraint the selection of workers into part time jobs and the wages they earn are analysed using the 1989 labour market activity survey we focus on the distinction between voluntary and involuntary part time workers since involuntary part time workers earn substantially lower wages than other workers we find that the selection of individuals into involuntary part time work is more closely tied to job characteristics than personal or human capital characteristics the lower wage earned by involuntary part time workers is largely due to differences in returns and selection effects rather than differences in endowments

inequality and attainment in a dual labor market models of wage determination and sector attainment are estimated for a cohort of young men in a dual labor market neoclassical economic vs dual labor market views on market equilibrium are contrasted although schooling is rewarded similarly in the primary and secondary sectors other results support the dual labor market view that employment in the primary sector is rationed via a queuing mechanism

expanding the behavioral foundations of labor economics the author examines critiques and suggests modifications to the psychological assumptions of the rational choice model of the human agent that underlies much of the theoretical work in modern neoclassical labor economics he analyzes the rational choice model in terms of three psychological constructs motivation cognition and emotion in the context of a five step model of the human behavioral process examples from the empirical and theoretical labor economics literature illustrate both problems with the current theory and new or improved insights and predictions that can be gained by incorporating additional psychological theories and concepts in economic analysis the author concludes that although the rational choice model is a powerful and productive conceptual device in many cases it cannot adequately explain behavior in the world of work and labor economic theory would be improved by a more interdisciplinary approach that integrates conceptual and empirical research from the behavioral sciences abstract courtesy jstor

modelling parallel markets in centrally planned economies the case of the automobile market in poland most empirical work dealing with socialist economies appears to be oriented towards macroeconomic problems or at least to the study of highly aggregated time series examples are provided by howard 1976 lacko 1975 podkaminer 1982 portes and winter 1980 portes et al 1983 1984a b 1985 welfe 1983 and charemza and gronicki 1988 only relatively infrequently has a particular market been the target of detailed empirical investigation a case in point is the study of the hungarian car market by kapitany kornai and szabo 1984 and chapter 15 of this volume

a selectivity model of employer size wage differentials this article investigates wage differentials for employees of different size firms utilizing an econometric methodology that allows the size of employer to be treated as endogenous in the context of discrete ordered employer size data as a result we are able to estimate i employer size wage gaps which are corrected for selectivity bias and ii the magnitude and direction of the selection bias decompositions of the resulting wage differentials are computed with comparisons of the conditional on sorting across employer size and unconditional wage gaps

systematic and random search a synthesis this paper synthesizes two models of search in the labor market systematic and random we construct and test a theoretical model in which the searcher is endowed with information on some possibly zero or all individual firms in the labor market as well as the overall wage offer distribution we test the model using a special wave of the 1976 current population survey the major theoretical results of our model are as follows searchers with lower stocks of knowledge about individual firms higher discount rates or having lower coverage by unemployment insurance are more likely to engage in random search activities

estimating the effects of unions on wage inequality in a panel data model with comparative advantage and nonrandom selection this article considers the estimation of the structure of wages in union and nonunion sectors it proposes an estimator that extends standard panel data techniques to the case in which the return to the permanent component of the error term is differently rewarded in the two sectors the econometric model is used to estimate the effect of unions on both the level and the variance of wages in canada the findings indicate that unions increase the average wage of workers and compress the returns to observable measures of skill and to a time invariant unobservable measure of skill

whose wages do unions raise a dynamic model of unionism and wage rate determination for young men we estimate the union premium for young men over a period of declining unionization 1980 87 through a procedure which identifies the alternative sources of the endogeneity of union status while we estimate the average increase in wages resulting from union employment to be in excess of 20 we find that the return to unobserved heterogeneity operating through union status is substantial and that the union premium is highly variable we also find that the premium is sensitive to the form of sorting allowed in estimation moreover the data are consistent with comparative advantage sorting our results suggest that the unobserved heterogeneity which positively contributes to the likelihood of union membership is associated with higher wages we are unable however to determine whether this is due to the ability of these workers to extract monopoly rents or whether it reflects the more demanding hiring standards of employers faced by union wages 1998 john wiley sons ltd

the effect of unions on wage inequality in the u s labor market this study uses current population survey micro data for 1973 74 and 1993 to evaluate the effect of changing union membership on trends in male and female wage inequality unionization rates of men fell between the two sample periods with bigger declines among lower skill groups these trends account for 15 20 of the rise in male wage inequality union membership rates of low wage women also declined while unionization increased among higher wage women on balance shifting unionization accounts for very little of the rise in female wage inequality economy wide trends in unionization mask a sharp divergence between the private sector where unionism was declining and the public sector where it was rising comparisons across sectors suggest that unionization substantially slowed the growth in wage inequality in the public sector

what occupational safety tells us about political power in union firms this article tests hypotheses on the distribution ofpower within unionized firms by measuring which workers preferences determine the level offirm supplied occupational safety an egalitarian model in which all workers have equal impact can be easily rejected as can a medianworker model the dominant groups appear to be the most senior workers with more than ten years of seniority and recently hired workers with three or fewer years of seniority this suggests that unions pursue the objectives of the most senior workers while management tries to set a safety level that is attractive to the more mobile workers

do us employers discriminate against females when hiring their employees using johnson s decomposition technique this paper demonstrates that the disappearance of the gap between female and male unemployment rates in the united states during the last decade results partly from a general hiring policy that is favourable to women workers this conclusion holds for workers in five out of eight occupational subsamples considered the sign and size of unexplained female male unemployment rate differential estimated from 1969 1977 and 1987 cps data suggest that hiring discrimination against females in the us labour market has declined considerably during the last two decades the study also supports the earlier finding that the growth of employment in government and in the female dominated service sector and migration of workers from the south to other regions contribute significantly to the convergence of male and female unemployment rates in the 1980s

unions wages and skills studies uniformly conclude that union wage effects are largest for workers with low measured skills longitudinal analysis using 1989 90 1994 95 cps matched panels produces union premium estimates equivalent across skill groups following appropriate sample restrictions and control for worker specific skills nlsy evidence on aptitude scores confirms that union workers with high measured skills have relatively low unmeasured skills differential selection by skill class and skill homogeneity in union workplaces result from employer and employee sorting in response to wage standardization union organizing where skills are homogeneous and unionized employers reluctance to hire the most as well as least able workers

sluggish institutions in a dynamic world can unions and industrial competition coexist during the 1930s and 1940s collective bargaining emerged as the workplace governance norm in much of the u s industrial sector following its peak in the 1950s union density in the u s private sector fell steadily to only 7 4 percent in 2006 governance shifted from a formalized union norm to one of constrained managerial discretion in competitive and dynamic economic environments a union tax on company earnings and slow response to economic shocks combine to produce poor performance by union companies two industries automotives and airlines are used to illustrate these points if worker based institutions are to flourish they must add value and permit companies to perform at levels similar to those obtained under evolving nonunion governance norms

labor market choices earnings and informal networks in khartoum sudan a micro economic labor force model was used to explain the relationship between five labor market segments and earnings in khartoum sudan the assumption was that individuals maximized their earnings by comparing the rewards of working in alternative and mutually exclusive segments of the labor market the polychotomous choice model allowing for unobserved factors used the hay dubin and mcfadden extension of heckmans technique for correcting for selection bias data were obtained from a private survey conducted by the authors during 1988 89 the sample included 1756 small scale enterprises and 1505 self employed workers and 2572 employees in the informal sector and 8037 workers in 170 formal sectors firms 12114 workers the five segments included public sector employment in the formal sector private sector employment in the formal sector private large self employed in the informal sector informal sector employees working in permanent structures private small and informal sector employees working for unlicensed firms without a permanent structure unprotected workers earnings were lowest in the unprotected segment and highest among self employed businessmen the model supported the view that private and large employers hired the best workers findings supported kannapans hypothesis that informal networks based on ethnicity were important in determining access to urban labor markets a high correlation was found between province of birth of the employer and employees the public sector earnings model had the highest degree of explanatory power of earnings differences wages in the private small and unprotected segments were also determined by education the findings suggested that studies of the rate of return to education should account for how social networks affect the probability of workers obtaining employment in a particular segment and should account for fixed wage rates in particular segments

reforms lobbies and welfare a common agency approach citizens with heterogeneous tastes delegate to policy makers the authority to choose public policies they may try to influence legislators in various ways in this paper we assume that monetary lobbying and direct threats are the only instruments private individuals can use to influence the legislator we model the relationship between the citizens and a single policy maker as a common agency game lobbies offer a policy and a payment according to a truthful contribution schedule and the government takes the policy decision in the truthful equilibrium the government implements the social surplus maximizing policy introducing also direct threats we find that as far as both groups have an instrument to influence the legislator the efficiency result is robust we also show that when the lobby groups have asymmetric interests and political power not all groups necessarily participate in the auction in particular it turns out that one lobby or non lobby equilibria may arise and those equilibria are also efficient

surprises in the consumption function the life cycle hypothesis has been the dominant theoretical basis for empirical work on the aggregate consumption function for about a quarter of a century under it real consumption is proportional to real life cycle wealth where the factor of proportionality depends on real interest rate expectations and the demographic structure of the population life cycle wealth is the sum of financial and human wealth however because the latter is the present real value of the stream of labour and transfer income expected over the life cycle it is not directly observable this fact has led to a great variety of proxying devices in empirical applications and in consequence much looseness in the interpretation of very different models as being all consistent with life cycle theory indeed one can argue that this has protected the hypothesis from being seriously tested and perhaps rejected an insight associated with friedman 1957 is that the view taken by consumers of life cycle income does not alter by much from period to period since there is greater persistence in life cycle income than in current income this also explains the greater persistence of consumption than of current income intuitively this would suggest that lagged consumption being related to last period s perception of life cycle income which in turn is not much different from this period s perception should have a major role in predicting current consumption this intuition was formalised by hall 1978 using ideas familiar from the study of stock market prices and the term structure of interest rates hall showed that if the real rate of interest is constant and given a number of other assumptions including no transitory element in consumption then the life cycle hypothesis implies that

slack shortage and discouraged consumers in eastern europe estimates based on smoothing by aggregation as a consequence of aggregation over markets the observed quantity may be less than the quantity demanded and less than the quantity supplied to deal with such situations a new technique is proposed for estimating demand and supply curves and the extent of shortage and slack the technique is applied to the consumption goods markets of czechoslovakia the german democratic republic hungary poland and yugoslavia it is found that shortage even corrected for a discouraged consumer effect is seldom as great as slack

why do workers join unions the importance of rent seeking union status models ignore the fact that rent seeking prospective members have an incentive to bid up entry costs so that higher union wage gains make union jobs more costly to obtain the standard presumption that higher union wages cause firms to substitute toward higher quality workers is shown to be incorrect under most plausible assumptions the observed positive correlation between wage gains and the propensity to join a union underestimates the size of the true supply response the union nonunion wage differential reveals more about the social cost of unions than the gain to an individual worker from union membership

wage differentials and moonlighting by civil servants evidence from cote d ivoire and peru as part of their efforts to reduce fiscal deficits many governments have allowed public sector salaries to erode often on the assumption that government workers are overpaid vis a vis those in the private sector that assumption is tested by analyzing public private pay differentials in cote d ivoire and peru switching regressions models are estimated using full information maximum likelihood fiml and the results are compared to those obtained using ordinary least squares ols techniques the ols yields seriously biased estimates of the pay structure suggesting that public wages are higher than private wages the fiml estimates show the opposite our probit analysis also shows that the wage disadvantage of civil servants is a determinant of the greater prevalence of moonlighting among public than private employees the evidence suggests that reductions in employment rather than pay while being less palatable in the short term will be more effective in the long run

a bivariate probit approach to the determination of employment a study of teen employment differentials in los angeles county following a bivariate probit approach and using the 1990 public use microdata samples pums for los angeles county this study shows that the employment of teenage workers depends on both the worker s participation decision as well as the employer s hiring decision omission of the role of participation decision from the estimation of employment probability yields misleading evidence of hiring discrimination against blacks this evidence however disappears when the participation and hiring equations are estimated jointly in a bivariate framework the study finds no evidence of discrimination against females and latinos in addition the study shows that family household and neighbourhood characteristics play significant roles in the determination of teen employment

wage effects of unionization and occupational licensing coverage in the united states recent estimates in standard models of wage determination for both unionization and occupational licensing have shown wage effects that are similar across the two institutions these cross sectional estimates use specialized data sets with small sample sizes for the period 2006 to 2008 the authors analysis examines the impact of unions and licensing coverage on wage determination using new data collected on licensing statutes that are then linked to longitudinal data from the national longitudinal survey of youth nlsy79 from 1979 to 2010 they develop several approaches using both cross sectional and longitudinal analyses to measure the impact of these two labor market institutions on wage determination the estimates of the economic returns to union coverage are greater than those for licensing statutes

union wages temporary lay offs and seniority it is widely believed that the seniority system in conjunction with the collective bargaining process contributes significantly to the determination of the unemployment level in unionized sectors causa i empiricism suggests that real wage demands often remain buoyant in these sectors in the face of seemingly high rates of unemployment among union members james medoff 1979 p 380 convincingly documents the evidence that adjustment through lay offs is substantially greater in unionized firms than in comparable non unionized firms the usual but somewhat informal explanation is that the outcome of union voting is greatly influenced by senior workers who are fairly certain that they will not be laid off when normal shifts in the industry s demand for labour occur 2 these inframarginal workers are believed to vote for higher wage settlements than they would if their own jobs were not so secure

computational controversies in disequilibrium and shortage modelling of centrally planned economies abstract most disequilibrium and shortage models of centrally planned economies fall into three categories testable excess demand the portes school disequilibrium indicators and kornai s economics of shortage these models have generated numerous controversies and conflicting empirical results however this paper argues that some disputes are not caused by the theoretical features of the models but rather by the utilisation of different estimation methods that are not directly comparable this suggests that several controversies are more apparent than real and can be resolved through the improvement of computational techniques and statistical hypothesis testing theory

international capital crunches the time varying role of informational asymmetries we examine the determinants of capital flows to four developing countries during the 1990s using an explicitly disequilibrium econometric framework in which the supply and demand for capital are not necessarily equal and the actual amount of the flow is determined by the short side of the market we are thus able to detect instances of international capital crunch where capital flows are curtailed because of supply side rationing and to relate these instances to movements in the underlying fundamentals the analysis highlights the role of asymmetric information as distinct from the traditional concern with default risk in conditioning capital flows

unemployment disequilibrium and the short run phillips curve an econometric approach the paper specifies a disequilibrium model for the aggregate labour market consisting of demand and supply functions for labour an adjustment equation for wages as well as for prices a transactions equation and finally an equation that relates measured unemployment to vacancies and to excess demand the model has a more sophisticated treatment of dynamics than earlier disequilibrium models the parameter estimates and the goodness of fit are satisfactory and the model s implications for the behaviour of several important variables are sensible in particular excess demand estimates computed in various ways are reasonable

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