wage norms and involuntary unemployment this paper and its sequel consist of a series of models or examples each trying to explain the possibility of non walrasian wage rates and involuntary unemployment equilibrium in recent years there have been many attempts to explain the possibility of equilibrium wages at non market clearing levels with involuntary unemployment there are the wage efficiency models yellen i984 contract models bargaining models e g shaked and sutton i984 to name but a few the common feature of these models and the ones i shall discuss is that involuntary unemployment for a certain range does not lead any agent to change his behaviour my models as in the works of lindbeck and snower i985 i986 are based on the distinction between insiders and outsiders in my models however workers and firms live for more than one period and as a result they may follow norms which are not in their short term interest but are rational in the longrun i shall model the labour market in a repeated game framework the literature on repeated games in recent years has shown that in general there are a large number of equilibria see fudenberg and maskin i986 a major application of repeated games has been to the industrial organisation literature where it has been shown that many types of behaviour on the part of firms e g collusion predatory pricing can be supported as equilibria of the game see fudenberg and tirole i984 my models which are applications of the repeated game to the problems of insiders and outsiders also contain many equilibria the walras ian outcome is one of the possible resulting equilibria there are also others the equilibria that i shall discuss however are those which may help us to understand some stylised facts and at the same time generate non walrasian outcomes i shall try to show that for some levels of unemployment each insider may rationally choose strategies which deter firms from trying to push the wages down and or deter unemployed from under cutting in this paper i shall define insider s as those who follow the norm if an insider deviates from the norm he loses his insider position the firm s agree s to pay higher wages than the market clearing rate because the insiders threaten to go on strike if the firm tries to force down the wages of any one of them and there are not enough unemployed workers to replace all insiders moreover the threat of each insider turns out to be credible because if he does not follow the norm he will lose his insider status and will not be protected by other insiders in the next period and thus will be at the mercy of the firm therefore in this paper the non walrasian outcomes are the result of the firm

relative wage positions and quit behavior evidence from linked employer employee data the authors analyze the importance of relative wage positions within firms in western germany in the context of individual quit decisions as an inverse measure of job satisfaction using a linked employer employee data set liab for the years 1996 2005 whose sample consists of full time male prime age workers in western germany without college degrees they ascertain whether workers find status or signal effects stronger motivators for quit decisions they find that workers with higher relative wage positions within their firms are on average more likely to quit their jobs than those with lower relative wage positions and that workers who experience a loss in their relative wage positions are also more likely to accept a wage cut associated with their job transition overall results suggest that a signal effect is on average stronger than a status effect

sources of intra industry wage dispersion how much do employers matter observed human capital explains less than half of wage variation in bls industry wage surveys establishment based wage differentials controlling for occupation account for 20 70 percent of intra industry wage variation this corresponds to a standard deviation in wages of 14 percent of the mean almost as large as interindustry wage variation investigation suggests that establishment wage differentials are not random variations or returns to usual measures of human capital

intertemporal consumer surplus in lagged adjustment demand models an application to natural gas pricing abstract applied welfare analyses of policy options typically measure surplus as a single period snapshot or a flow over time assuming stationary supply and demand curves these curves however generally are not independent of time therefore the effects of various policy changes are likely to differ in type and magnitude over time as adjustments are made this paper presents an algorithm for calculating the welfare effects of a policy change in the context of commonly used lagged adjustment demand models an example involving natural gas price decontrol is presented in this example assuming stationary demand curves would overestimate lost consumer surplus by 15

what do unions maximise evidence from survey data highly formalised models of union behaviour have been developed and are widely used within neoclassical economics this approach is justified by the argument that most goals pursued by unions can be reduced to a wage or wage equivalent employment trade off however the strong assumptions made about union goals and preferences how these are determined and the range of issues over which a union will seek to bargain with a firm are not supported by extensive empirical evidence this paper explores these issues through a survey of union leaders to ascertain the range of union goals and their preferences and the types of issues over which unions bargain with employers the results of the survey present convincing evidence that standard neoclassical models do not adequately capture union bargaining behaviour or union goals and preferences the findings presented here also throw open but do not resolve the question of whether unions are rational maximisers the most inter esting result not widely found within the economics or industrial relations literature concerns the nature of union bargaining preferences union bargaining over employment appears to be asymmetric around current levels of employment in that unions appear to care more about the employment implications of their bargain ing strategies when they are likely to result in employment decreases

efficiency wage models of unemployment one view h lorne carmichael persistent wage rigidity and involuntary unemployment appear to be recurrent problems in most economies what could be preventing the wage adjustment necessary to clear the labor market many recent papers claim to have found the answer in efficiency wage models this paper surveys this literature and attempts to evaluate its accomplishments it concludes that the efficiency wage models fail to explain wage rigidity or persistent involuntary unemployment persistent involuntary unemployment of workers is a recurrent problem in labor markets all over the world unemployed workers seem unable to find work even though they are willing to accept lower wages than those being paid employed workers with similar skills what could be preventing wages from adjusting to clear these markets many recent papers known collectively as the efficiency wage literature now claim to have the answer this paper will survey the efficiency wage literature and critically evaluate some of its accomplishments efficiency wage models have already been examined by yellen 1984 katz 1986 and stiglitz 1987 and have received generally favorable reviews this paper is more critical its overall conclusion is that efficiency wage models provide some useful insights into the workings of the labor market but they do not provide a satisfactory account of wage rigidity or involuntary unemployment there are at least five separate versions of the efficiency wage model they share a common structure however and this is outlined in the first section of the paper this section also attempts to relate efficiency wage models to other recent models of unemployment section ii examines and criticizes the different approaches in detail section iii evaluates the achievements of this approach and suggests some directions for future work i a general efficiency wage model efficiency wage models as the name suggests are first of all models of wages they generate unemployment by showing that firms will sometimes want to set wages at non market clearing levels it is useful to begin therefore by reviewing how wages and employment are determined in some related models in a perfectly competitive labor market the wage for each type of labor is adjusted constantly to maintain equality of supply and demand overall employment fluctuates in response to demand changes as workers move up and down their labor supply curves unemployment is voluntary in that anyone who is not working prefers that state to employment at the going wage for people of his skills as well the value of a worker s marginal product is equal to the marginal value of his leisure so there are no unexploited wage bargains between unemployed workers and firms this model is successful in predicting the long term response of wages to shifts in demand and supply but it is clear that in the short run its depiction of voluntary unemployment and flexible wages is unrealistic a natural way to generate more realism is to assume that wages are inflexible in the short run in this case a reduction in demand away from a long run equilibrium will lead to rationing of jobs by employers as they attempt to stay on their labor demand curves the unemployment here is involuntary in that the unemployed would prefer to be working at the going wage and is inefficient in that there are lost gains from trade between these workers and firms the weakness of this model is that it is silent about the mechanism that keeps wages rigid unemployed workers who offer to work for less than the fixed wage ought to find work the early implicit contract models of azariadis 1975 baily 1974 and gordon 1974 provide one explanation for wage rigidity these models introduced the idea that wages can do more than just clear the market for labor wages in an implicit contract model are used to shift the risk generated by uncertain output market conditions from risk averse workers to the risk neutral firm

aggregate consumer behaviour and the measurement of inequality this paper presents an approach to inequality measurement based on an econometric model of aggregate consumer behaviour the novel feature of this model is that systems of individual demand functions can be recovered uniquely from the system of aggregate demand functions we present methods for evaluating social welfare based on an explicit social welfare function this social welfare function incorporates measures of individual welfare based on indirect utility functions for all consumer units we develop indexes of inequality based on actual and potential levels of social welfare

bargaining cycles and work related attitudes evidence for threat rigidity effects in this study we proposed that union members would be more similar in their attitudes toward bargaining related outcomes during contract negotiation years than union members at other stages of the

wages and employment under trade unionism microeconomic models and macroeconomic applications the first part of this paper is a critical survey of microeconomic research into behavioural models of trade unionism although certain formulations of union objectives and models of wage and employment determination in unionized markets have found favor with economists unfortunately only a little is known about their empirical relevance the second part of this paper deals with the daunting problems of applying these models at the macroeconomic level one such model is estimated with data from sweden s mining and manufacturing sector from 1968 to 1982

evaluating unemployment policies what do the underlying theories tell us the paper surveys unemployment policies for advanced market economies and evaluates them by examining the predictions of the underlying macroeconomic theories the basic idea is that for the most part different unemployment policy prescriptions rest on different macroeconomic theories and our confidence in the prescriptions should depend at least in part on theories ability to predict some salient stylized facts about unemployment behavior the paper considers four types of policies laissez faire demand management policies supply side policies and structural policies copyright 1995 by oxford university press

chasing after good jobs do they exist and does it matter if they do most people believe that there are such things as good jobs jobs that a worker would consider herself lucky to get but for economists the existence of good jobs is debatable in this paper i provide a definition of a good job based on various theories of the labour market a job that involves a surplus captured partly by the worker i use that definition to guide an empirical investigation of the existence and importance of good jobs i conclude that good jobs do exist that the labour market does not just function according to a roy model with wage differentials reflecting only skill differentials compensating differentials or bond posting and that their impact on the overall wage structure is substantial finally i discuss the implications of the existence of good jobs for policy setting and for assessments of the justice of a society resume la chasse aux bons emplois est ce qu ils existent et est ce que cela importe qu ils existent la plupart des gens croient qu il y a telles choses que de bons emplois des emplois qu un travailleur se trouverait chanceux d avoir mais pour les economistes l existence de bons emplois est discutable dans ce texte l auteur propose une definition de bon emploi fondee sur diverses theories du marche du travail un emploi qui engendre un surplus capture en partie par le travailleur il utilise cette definition pour guider son enquete empirique sur l existence et l importance de bons emplois on conclut que les bons emplois existent que le marche du travail ne fonctionne pas seulement selon le modele de roy avec des differentiels de salaires qui refletent seulement les differentiels d habiletes les differentiels compensatoires ou le depot d une caution et que leur impact sur la structure globale des salaires est substantielle finalement l auteur discute les implications de l existence de bons emplois sur la definition de politiques et sur l evaluation du caractere juste d une societe

union wage setting and unemployment in the netherlands 1965 1987 this paper presents an empirical model of union wage setting and employment the stackelberg equilibrium unemployment rate is shown to be a function of taxes the replacement ratio the gap between consumer and producer prices productivity effects and the rate of long term unemployment the model is estimated with aggregate data from the private sector in the netherlands 1965 1987 the results suggest that the equilibrium unemployment rate is pushed upwards by taxes the replacement ratio and by the gap between consumer and producer prices and is reduced by productivity effects insider outsider effects appear insignificant

a dynamic analysis of marketing orders voting and welfare this paper presents a dynamic model of how profit maximizing farmers would vote on marketing order rules given that new firms will enter based on rational expectations perfect foresight about the path profits follow early entrants make large short run gains while in the long run marginal firms break even welfare analyses under a dynamic model differ substantially from the static analyses normally reported an evaluation of the profit and welfate effects of marketing orders requires explicit recognition of the gains to be made during the transition from a competitive equilibrium to a regulated equilibrium this paper presents a dynamic model of how profit maximizing farmers would vote on marketing order rules given that new firms will enter based on rational expectations perfect foresight about the path profits follow most previous studies are static and have contrasted the competitive long run equilibrium with the regulated long run equilibrium virtually all of the studies on fruit and vegeta

wages and employment in a segmented labor market this paper analyzes the impact of business cycle fluctuations on a labor market segmented into a unionized primary sector and a competitive secondary sector either permanent or temporary changes in real aggregate demand are shown to widen the intersectoral wage differential in recession and under reasonable specifications of key parameters to cause greater fluctuations of primary sector employment than secondary sector employment this pattern agrees with the stylized facts of the u s economy

do turnover costs protect insiders the ability of insiders to extract rents associated with exogenous turnover costs is addressed in a dynamic model the higher these rents the higher is the incentives for outsiders to obtain future insider status and thus to underbid current insiders as a consequence there is a lower limit to the number of insiders that can avoid entrance of outsiders and the insiders cannot in each period obtain a rent equal to the turnover costs the insider model never explains a lower but may result in a higher employment level than in the case where all workers are wage takers copyright 1994 by royal economic society

on union preferences and labour market models insiders and outsiders this paper constructs a model of trade union behavior in which there is a distinction between insiders and outsiders this is used to examine one of the most troublesome issues in macroeconomic theory namely the extent to which a rise in aggregate demand might generate wage increases rather than growth in employment a generalization of the most widely used union utility function is presented the analysis reveals the conditions under which insiders will agree to let outsiders into employment derives two step wage preferences and proves a new result on wage rigidity copyright 1987 by royal economic society

cyclical variations in wage differentials and unemployment this paper attempts to reformulate in a general equilibrium framework reder s model which explains cyclical variations in wage differentials and their general tendencies to narrow specifically i focus on the three aspects of his model the microeconomic behavior of a firm under imperfect information about labor quality the mechanism of the economy creating unemployment and the interaction between wage differentials and unemployment i also explore its implications for the macroeconomic issues on the characteristics of current unemployment and the question of why aggregate employment fluctuates

rent sharing in an equilibrium model of matching and turnover this article characterizes labor markets in which the heterogeneity of workers and firms results in thin markets and rents neoclassical marginal analysis and matching are blended into a computable general equilibrium model of trade in efficiency units of labor although workers bargaining problems are interrelated a simple wage contract generates wage flexibility and efficient matching in the model s equilibrium equilibrium wages are predicted to vary with the diversity of firms the scarcity of skills and the costliness of search the model is applied to superstar markets union bargaining in sports interindustry wage differentials and the relationship between pay and profit

did henry ford pay efficiency wages we examine henry ford s introduction of the five dollar day in 1914 in an effort to evaluate the relevance of efficiency wage theories of wage and employment determination we conclude that the ford experience strongly supports the relevance of these theories ford s decision to increase wages dramatically is most plausibly the consequence of labor problems of the kind efficiency wage theorists stress the structure of the five dollar day program is consistent with the predictions of efficiency wage theories there is vivid evidence that the introduction of the five dollar day resulted in substantial queues for ford jobs significant increases in ford productivity and profits accompanied the new regime

explanations of unemployment economists commonly distinguish between two sorts of unemployment roughly speak ing the involuntarily unemployed workers are unwillingly out of work i e they feel that they would be better off with jobs on the other hand the voluntarily unemployed workers prefer to be out of work for any of a wide variety of reasons e g because they are searching or training for a job or because they choose leisure over work

premiums to employment in larger establishments evidence from peru abstract examination of the employer size wage effect for males in urban peru suggests the following higher wages in larger establishments do not merely compensate for higher worker quality or inferior working conditions size differences in the use of rising wage tenure profiles cannot provide a market clearing explanation for the employer size wage effect unless workers are extremely impatient thus larger employers appear to pay premiums unionization explains none of the premiums and minimum wage compliance explains at best a small fraction shirking based efficiency wage explanations for premiums are implausible because peruvian job security legislation greatly inhibits dismissals in larger establishments explanations meriting further research involve the use of high wages to reduce turnover and to improve productivity enhancing morale

panel estimates of the canadian rural urban women s wage gap this article analyzes the female rural urban wage gap in canada using longitudinal data from the survey of labour and income dynamics 1993 96 we estimate a two step wage equation accounting for unobserved heterogeneity and sample selection the results indicate that a statistically and economically significant rural urban wage gap remains after controlling for observed and unobserved characteristics further the results suggest this rural urban wage difference is not simply induced by immobility between rural and urban markets rather consistent with the effect of thinner rural labor markets the evidence indicates that rural urban differences in the impact of a number of explanatory variables are significant

insiders and outsiders in wage determination a firm starts with a group of insiders or seasoned workers there is also a large pool of outsiders who are initially less productive but are transformed into insiders after one period of employment the firm gains from having a large pool of insiders some of whom may be laid off in bad years insiders gain from keeping their numbers small if the insiders set their wage unilaterally they will choose a path that in this extreme case prevents employment of outsiders even if future employment prospects are good if the wage path is set by bilateral bargaining the extra advantage to the firm permits employment of some outsiders in some situations

interindustry wage differentials and efficiency wages some canadian evidence using the 1986 labour market activity survey as their major source of data the authors estimate interindustry wage differentials in canada at the one and two digit levels of industry aggregation for various types of workers the major findings are that substantial interindustry wage differentials exist and are relatively stable over time that the pattern of interindustry wage differentials is very similar for different kinds of workers and that these differentials cannot be explained easily by compensating factors the differentials seem to be consistent with the rent sharing explanations of the labor market such as those based on the notion of efficiency wages

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

trade unions wage formation and macroeconomic stability an introduction the process of wage formation is a crucial aspect of the current discussion about the causes of stagflation in fact differences between various policy prescriptions usually depend on differing assumptions about wage responses proposals to reduce unemployment through expansion of monetary demand are usually based on assumptions of rigid money wages in contrast recommendations of non intervention policies often rest on the opposite assumption of rigid real wages in which case monetary expansion will cause inflation but not affect employment

job recruitment networks and migration to cities in india abstract economists have focused on job search and supply side explanations for network effects in labour transactions this paper develops and tests an alternative explanation for the high prevalence of network based labour market entry in developing countries in our theoretical framework employers use employee networks as screening and incentive mechanisms to improve the quality of recruitment our framework suggests a negative relationship between network use and the skill intensity of jobs a positive association between economic activity and network use and a negative relationship between network use and pro labour legislation furthermore social identity effects are expected to intensify when compared to information sharing and other network mechanisms using data from an all india employment survey we implement a novel empirical strategy to test these relationships and find support for our demand side explanation

a theory of dual labor markets with application to industrial policy discrimination and keynesian unemployment this paper develops a model of dual labor markets based on employers need to motivate workers in order to elicit effort from their workers employers may find it optimal to pay more than the going wage this changes fundamentally the character of labor markets the model is applied to a wide range of labor market phenomena it provides a coherent framework for understanding the claims of industrial policy advocates it also can provide the basis for a theory of occupational segregation and discrimination that will not be eroded by market forces finally the model provides the basis for a theory of involuntary unemployment

compensating differentials for shift work a model analyzing the choice of shift is developed and estimated using data from two supplements to the current population survey the findings show a positive wage premium for shift work that varies with personal characteristics and there is strong evidence showing the importance of self selection as workers with low potential daytime earnings are more likely to choose night work and supplement their earnings the findings demonstrate that cross section estimates of wage premiums for union membership and firm size are biased upward because they pick up some of the compensating differential for shift work

the determinants of strike incidence and severity a micro level study this paper investigates the determinants of strike incidence and severity during labor contract negotiations the author develops a model that considers the forces influencing both unions willingness to strike and employers willingness to take a strike and estimates it using data describing 1 050 negotiations in u s manufacturing during the 1971 80 period the results indicate that strike incidence is influenced by the gender composition of the labor force demand fluctuations in the product market location in a right to work state the number of workers in the bargaining unit union density in the industry and the extent to which wages kept pace with inflation over the prior contract period on the other hand neither the local unemployment rate when negotiations began nor the inflation rate over the term of the expiring contract influenced strike incidence or severity in this sample

job security work incentives and unemployment this paper analyzes how firms can use job security as an incentive mechanism the author examines how macroeconomic job security measured by the reemployment probability may affect productivity differently from microeconomic job security measured by the probability of being retained the authors describe the circumstances under which job security stimulates work effort then incumbent workers insiders may have an opportunity to raise their wages above the market clearing level without being replaced by unemployed workers outsiders in this context involuntary unemployment can arise copyright 1988 by the editors of the scandinavian journal of economics

consumer s surplus without apology the purpose of this paper is to settle the controversy surrounding consumer s surplus and by so doing to validate its use as a tool of welfare economics i will show that observed consumer s surplus can be rigorously utilized to estimate the unobservable compensating and equivalent variations the correct theoretical measures of the welfare impact of changes in prices and income on an individual i derive precise upper and lower bounds on the percentage errors of approximating the compensating and equivalent variations with consumer s surplus these bounds can be explicitly calculated from observable demand data and it is clear that in most applications the error of approximation will be very small in fact the error will often be overshadowed by the errors involved in estimating the demand curve the results in no way depend upon arguments about the constancy of the marginal utility of income consequently this paper supplies specific empirical criteria which can replace the apologetic caveats frequently employed by those who presently apply consumer s surplus moreover the results imply that consumer s surplus is usually a very good approximation to the appropriate welfare measures to preview below i establish the validity of these rules of thumb for a

migration and imperfect labor markets theory and cross country evidence from denmark germany and the uk we investigate the labor market effects of immigration in denmark germany and the uk three countries which are characterized by considerable differences in labor market institutions and welfare states institutions such as collective bargaining minimum wages employment protection and unemployment benefits affect the way in which wages respond to labor supply shocks and hence the labor market effects of immigration we employ a wage setting approach which assumes that wages decline with the unemployment rate albeit imperfectly we find that the wage and employment effects of immigration depend on wage flexibility and the composition of the labor supply shock in germany immigration involves only moderate wage but large unemployment effects since immigrants are concentrated in labor market segments with low wage flexibility the reverse is true for the uk and denmark

why capital hires labor a bargaining perspective organizational forms often serve as vehicles for the appropriation of quasi rent capitalist firms typically emerge when production requires noncontractible investments in specific physical assets because worker control would divert quasi rents away from ass et owners ex post conversely labor managed firms tend to emerge in niches requiring specialized human capital but general purpose physi cal assets a key result is that capitalist firms can persist in competitive markets even when labor managed firms would yield a larg er total surplus copyright 1993 by american economic association

membership seniority and wage setting in democratic labour unions the dynamic behavior of a democratic monopoly labor union that allocates employment on a length of service basis is studied in the context of a simple model the author shows that a median voter equilibrium can exist in a union consisting of senority ranked workers when voting membership depends on past employment the closed form wage rule of such a union induces a unit root in the autoregressive representation of employment even if the underlying determinants of labor demand are strictly stationary on the other hand chesire cat or disappearing union phenomena are likely to be limited by the forward looking behavior of union members and the sensitivity of union membership to employment copyright 1990 by the london school of economics and political science

efficiency wage models of unemployment keynesian economists hold it to be self evident that business cycles are characterized by involuntary unemployment but construction of a model of the cycle with involuntary unemployment faces the obvious difficulty of explaining why the labor market does not clear involuntarily unemployed people by definition want to work at less than the going wage rate why don t firms cut wages thereby increasing profits

trade unions and seniority employment rules abstract some but not all trade union and insider outsider models assume that a seniority employment rule is used we investigate when firm and union members gain from such a rule and the consequences of their adopting one generally providing a seniority wage scale is also used they gain if union membership is not too large relative to demand and union bargaining power not too great moreover when outsiders are hired under a seniority employment rule employment is at the competitive level these results might explain why bargaining over employment is relatively uncommon and typically occurs only in industries with declining employment

human capital vs signalling explanations of wages increases wages by directly increasing the worker s productivity this learning explanation is usually associated with human capital theory however it seems unlikely that learning explains all the wage differences associated with schooling and work history better educated workers are not a random sample of workers they have lower propensities to quit or to be absent are less likely to smoke drink or use illicit drugs and are generally healthier it is unlikely that employers make full use of differences in propensities to quit or to be absent or sick when hiring workers these characteristics are often not directly observed and the americans with disabilities act precludes firms from using either poor health or the likelihood of future sickness as a hiring criterion unless it is directly related to job performance however if low levels of education are associated with these unfavorable employee characteristics and employers are allowed to take education into account when hiring workers we would expect employers to favor better educated workers as a means of reducing their costs of sickness and job turnover in turn students will take these hiring criteria into account when deciding how long to stay in school students will choose a length of schooling to signal their ability to employers and employers will demand a minimum level of schooling

a model of the natural rate of unemployment since the publication of edmund phelps volume the new macroeconomics has treated the labor market as a dynamic process of rational search by unemployed workers for available vacancies wages are viewed as at least potentially flexible though free contracting between workers and firms may lead to fixed wages in the short run imperfect information is a crucial element of the theory for it implies both a need for contracting and a need for rational search rather than simple market clearing in each period a positive rate of frictional unemployment may exist in equilibrium denoted as the natural rate this unemployment is due to the frictions in the search process and imperfections in information rather than to any deficiency in aggregate demand milton friedman defined the natural rate as the level that would be ground out by the walrasian system of general equilibrium equations provided there is embedded in them the actual structural characteristics of the labor and commodity markets including market imperfections stochastic variability in demands and supplies the cost of gathering information about job vacancies and labor availabilities the costs of mobility and so on p 8 this paper reexamines the micro foundations of the natural rate in a model of labor market equilibrium in which turnover flows and imperfect information are explicitly considered workers may quit their current jobs to enter the unemployment pool in order to search among available vacancies for a more preferred position firms economize on turnover by an appropriate wage policy

unemployment in regional labor markets using structural theories to understand local jobless rates in west virginia the author uses a range of structural labor market models to understand differing regional jobless rates in a state affected by pockets of structural unemployment four theories of regional structural unemployment are presented and their hypotheses are statistically evaluated using west virginia county panel data the author then presents case study evidence to compare these statistical results with the realities of the county labor markets both types of empirical evidence suggest that a segmented non market clearing model in which structural unemployment stems from queuing for above market clearing wages in both a high wage primary sector and a lower wage secondary sector can shed the most light on regional unemployment rates in west virginia

insiders outsiders and nominal wage contracts while the consequences of nominal wage contracts have been rather thoroughly analyzed there is no generally accepted theory of why such contracts prevail in this paper i argue that the distinction between insiders and outsiders is important for understanding nominal wage contracts since most employment fluctuations take the form of fluctuations in hiring insiders are normally not affected by them since prices are primarily determined by costs demand shocks have small effects on real wages thus insiders have little incentive to change to more complicated contracts with rigid nominal wages nominal demand shocks have large effects on the employment opportunities of outsiders but outsiders have little influence on labor contracts

an empirical study of age discrimination in norway and germany using a questionnaire and a sample of students and personnel managers we establish the existence of age discrimination in the hiring process in germany and norway as expected age discrimination is more prominent in germany where the hiring probability of equally qualified applicants is reduced by about 22 percentage points due to an age differential of 14 years as opposed to only 12 percentage points in norway within both countries the tendency to discriminate does not differ between students and personnel managers and does not depend on the age of the decision maker the phenomenon of unemployment among older workers is characterized less by the risk of becoming unemployed than by the problem of remaining unemployed and failing to find new work frerichs and naegele 1998 p 59

sectoral shifts and interindustry wage differentials the observed differences in wages across industries may arise from a lack of worker mobility particularly among experienced workers allowing the effects of industry shocks to persist for some time although young workers arbitrage wage shocks they will have little effect on the dispersion of experienced workers wages if young and old workers are poor substitutes in production this explanation is investigated using the five censuses of population between 1940 and 1980 the evidence strongly suggests that differences in pay are not temporary phenomena the data provide some support for the role of human capital and ability
