when strong ties are strong networks and youth labour market entry the conditions under which young workers find their first real post graduation jobs are important for their future careers and insufficiently documented given their potential importance for young workers welfare to study these conditions and in particular the role played by social ties we use a swedish population wide linked employer employee data set of graduates from all levels of schooling that includes detailed information on family ties neighbourhoods schools class composition and parents and children s employers over a period covering years with both high and low unemployment together with measures of firm performance we find that strong social ties parents are an important determinant for where young workers find their first job the effects are larger if the graduate s position is weak low education bad grades during high unemployment years and when information on potential openings are likely to be scarce on the hiring side by contrast the effects are larger if the parent s position is strong long tenure high wage and if the parent s plant is more productive the youths appear to benefit from the use of strong social ties through faster access to jobs and by better labour market outcomes as measured a few years after entry in particular workers finding their entry jobs through strong social ties are considerably more likely to remain in this job while experiencing better wage growth than other entrants in the same plant firms also appear to benefit from these wage costs relative to comparable entrants starting at a lower base they also benefit on the parents side parents wage growth drops dramatically exactly at the entry of one of their children in the plant although this is a moment when firm profits tend to be growing indeed the firm side benefits appear large enough for at least small firms to increase job creation at the entry level in years when a child of one of their employees graduates

does increasing women s schooling raise the schooling of the next generation the positive cross sectional relationship between the schooling of mothers and their children is substantially biased upward due to correlations between schooling and heritable ability as well as assortative mating an increase in the schooling of women would not have beneficial effects in terms of the schooling of children increased maternal schooling leads to reduced home time for mothers anticipating the consequences of investing in women s schooling requires attention to the role that schooling plays in the marriage market as well as to opportunities in the labor market for women

self recruitment in the legal profession we argue that lawyers sons follow in their parents footsteps because the occupation lends itself to low cost transfer of relevant skills and knowledge from one generation to the next especially in the context of the family law practice analysis of project talent data reveals that knowledge about the law is transmitted from lawyers to their children and that this transmitted knowledge is a significant factor in a son s decision to follow in his father s legal footsteps second generation lawyers who receive these human capital transfers experience greater earnings than lawyers who have not received such transfers

quasi fixed inputs in u s and japanese manufacturing a generalized leontief restricted cost function approach in this paper a generalized leontief variable cost function is develope d which permits analytical derivation of steady state levels of quasi fixed inputs and capacity output and does not require specification of a numeraire input this framework is then used to evaluate the fa ctor demand patterns of japanese and u s manufacturing based on bot h one quasi fixed capital input and two quasi fixed capital and la bor input specifications and both static and dynamic optimization t he findings provide evidence of considerable flexibility of demand re sponses in japan which may have contributed to japan s relatively st rong economic performance in the volatile 1970s copyright 1988 by mit press

social contacts and occupational choice social contacts help workers to find jobs but those jobs need not be in the occupations where workers are most productive hence social contacts can generate mismatch between a worker s occupational choice and his comparative productive advantage thus economies with dense social networks can exhibit apparently low labor force quality and as a result low returns to firms investment and depressed aggregate productivity we employ us and european data for the 1990 s to test the key prediction that social contacts distort workers occupational choices in a direction that reduces their apparent productivity we find that the use of social contacts helps find jobs one to two months sooner but leads to individual wage discounts of 5 to 7 and produces negative externalities on aggregate productivity

intergenerational income mobility in the united states social scientists and policy analysts have long expressed concern about the extent of intergenerational income mobility in the united states but remarkably little empirical evidence is available the few existing estimates of the intergenerational correlation in income have been biased downward by measurement error unrepresentative samples or both new estimates based on intergenerational data from the panel study of income dynamics imply that the intergenerational correlation in long run income is at least 0 4 indicating dramatically less mobility than suggested by earlier research copyright 1992 by american economic association

job information networks neighborhood effects and inequality this paper explores the theoretical and empirical literature to examine the use by different social groups of informal sources of information provided by friends relatives and acquaintances during job search and its consequences for the job market it also addresses the role of network structure and size the resource endowments of contacts and nature of the links between contacts to explain differences in the effects of job information networks in doing so the paper also turns to the sociology literature on job information networks and provides an economic perspective on such sociological concepts as strong versus weak ties inbreeding distance from structural holes etc the paper distinguishes between models of exogenous job information networks that is where individuals obtain job related information through a given social structure and endogenous job information networks which are social networks that result from individuals uncoordinated actions the paper pays special attention to such issues as physical and social proximity and sharing of information and discusses them in the context of the recent social interactions and neighborhood effects literature finally the paper outlines a model that integrates job information networks where interactions occur in business cycle frequencies with the dynamics of human capital formation which include the joint effects of parental community and neighborhood human capital and are set in life cycle frequencies for the purpose of organizing suggestions for future research and examining earned income inequality

do friends and relatives really help in getting a good job informal contacts are extensively used by both firms and workers to find jobs and fill vacancies the common wisdom in the economic literature is that jobs created through this channel are of better quality and pay higher wages than jobs created through formal methods this paper explores the empirical evidence for european countries using the european community household panel echp and discovers a large cross country as well as cross industry variation in the wage differentials between jobs found through informal and formal methods across countries and industries wage premiums and wage penalties to finding jobs through personal contacts are equally frequent this paper argues that such variation can be explained by looking at firms recruitment strategies in labour markets where employers invest largely in formal recruitment activities matches created through this channel are likely to be of average better quality than those created through informal networks a simple theoretical model is used to show that employers invest more in recruitment for high productivity jobs and for positions that require considerable training the empirical predictions of the theory are successfully tested using industry level data on recruitment costs

with a little help from my friends quality of social networks job finding and job match quality this paper studies the effect of network quality on job finding and job match quality using longitudinal data and a direct measure of network quality which is based on the employment of friendship ties various identification strategies provide robust evidence that a higher number of employed contacts increases the job finding rate network quality also increases wages for high skilled workers forming networks with non familial contacts instead for low skilled workers more employed familial contacts lead to a negative but not significant effect on wages these findings reconcile previous mixed evidence of network effects on wages indicating heterogeneity by skill level and relationship type

people i know job search and social networks we assess the strength of information spillovers relating unemployment duration of workers displaced by firm closures to their former colleagues current employment status displaced specific networks are recovered from a 20 year panel of matched employer employee data spillovers are identified by comparing performances of codisplaced workers a one standard deviation increase in the network employment rate reduces unemployment duration by about 8 the effect is magnified if contacts recently searched for a job and if their current employer is spatially and technologically closer to the displaced worker stronger ties and lower competition for information favor reemployment several indirect tests exclude other interaction mechanisms

scale effects time varying markups and the cyclical behaviour of primal and dual productivity this paper presents estimates of the degree of returns to scale using nonparametric measures of primal and dual productivity for 2 digit us manufacturing industries as part of the analysis the cyclical behaviour of primal and dual productivity measures are considered time varying markups are allowed for and the small sample properties of the instrumental variables estimator used to derive the estimates from the primal and dual relations examined both the primal and dual estimates indicate the existence of increasing returns to scale for the durable goods industries the simulation results indicate there is a slight tendency for the dual equation estimates to overestimate the degree of returns to scale however small sample bias appears to be most severe for the non durable goods industries

informal job search and black youth unemployment in this paper i analyze how young black and white unemployed jobseekers use various methods of search and the employment outcomes which result from their use the focus is on distinguishing informal search methods i e friends and relatives or direct application without referral from more formal ones in analyzing racial differences the results show that the two informal methods of search account for about 90 of the difference in employment probabilities between white and black youth this also accounts for 57 71 of the difference in unemployment rates between the two furthermore most of these results reflect differences in the ability of these methods to generate job offers as opposed to differences in search effort or job acceptance rates however our ability to explain these differences through personal family and household characteristics was generally quite limited this abstract was borrowed from another version of this item

the cyclical nature of markups in canadian manufacturing a production theory approach in this paper the effects of cost and demand characteristics on the magnitude and cyclical behaviour of markups in canadian manufacturing are measured within a production theory framework price to marginal cost ratios for various manufacturing industries are computed and the impact art their secular and cyclical trends from changes in capacity utilization scale economies variable input prices import competition unemployment and other exogenous market and technological determinants are explored using adjusted markup indexes and elasticities the measured price margins seem weakly procyclical further evaluation of the determinants of these cycles suggests that the procyclical nature of markups is primarily related to exogenous factors affecting costs such as energy price shocks and that cost characteristics underlying scale economies provide a countercyclical influence that counteracts the profitability arising from markups

the relation between price and marginal cost in u s industry an examination of data on output and labor input reveals that some u s industries have marginal cost well below price the conclusion rests on the finding that cyclical variations in labor input are small compared with variations in output in booms firms produce substantially more output and sell it for a price that exceeds the costs of the added inputs the paper documents the disparity between price and marginal cost where marginal cost is estimated from annual variations in cost it considers a variety of explanations of the findings that are consistent with competition but none is found to be completely plausible

the economics of casino taxation in this article a model of the costs of a casino is developed that focuses on the implications for economic welfare of different taxation schemes for casinos the situation being considered is in a country where casinos cater exclusively to foreign tourists the goal of the country is to determine the maximum amount of taxes that can be extracted from the activities of this sector under different systems of taxation when the price of gambling is set by regulation above its competitive level the economic losses created by excessive investment in the sector can be reduced by taxation a turnover tax on the amount gambled can maximize both tax revenue and the economic welfare of the country due to administrative constraints a number of countries rely on the taxation of the casinos fixed assets or a combination of a turnover tax and a tax on fixed costs the model is applied to the situation in north cyprus the annual economic efficiency loss from its poorly designed tax policies on casino gambling is

do parental networks pay off linking children s labor market outcomes to their parents friends this paper examines whether children are better off if their parents have stronger social networks using data on high school friendships of parents we analyze whether the number and characteristics of friends affect the labor market outcomes of children while parental friendships formed in high school appear long lasting we find no significant impact on their children s occupational choices and earnings prospects these results do not change when we account for network endogeneity network persistency and network measurement error only when children enter the labor market we find that friends of parents have a marginally significant but small influence on the occupational choice of children

economic fluctuations market power and returns to scale evidence from firm level data recent research on aggregate fluctuations coupled with ongoing work in industrial organization has renewed interest in the existence magnitude and cyclical pattern of market power and the extent of increasing returns to scale by exploiting restrictions from dynamic theory and information from financial markets we present a framework for generating quantitative evidence on market power and returns to scale tailoring the econometric model to firm level panel data we calculate the percentage differential between price and marginal cost the lerner index in terms of the parameters from the econometric system results for firms in eleven industries indicate that there is a great deal of heterogeneity in the extent of market power industries with significantly positive lerner indices tend to have substantial increasing returns in the production technology we find that there is only a modest relation between our estimated lerner indices and traditional measures of market power and that when market power varies temporally it is usually procyclical thus variations in the markup of price over marginal cost may help dampen aggregate economic fluctuations

ethnic enclaves and the economic success of immigrants evidence from a natural experiment recent immigrants tend to locate in ethnic enclaves within metropolitan areas the economic consequence of living in such enclaves is still an unresolved issue we use an immigrant policy initiative in sweden when government authorities distributed refugee immigrants across locales in a way that may be considered exogenous this policy initiative provides a unique natural experiment which allows us to estimate the causal effect on labor market outcomes of living in enclaves we find substantive evidence of sorting across locations when sorting is taken into account living in enclaves improves labor market outcomes for instance the earnings gain associated with a standard deviation increase in ethnic concentration is in the order of four to five percent

the cyclical behavior of marginal cost and price the author examines the cyclical behavior of price marginal cost margins for u s manufac turing after 1956 short run marginal cost is markedly procyclical this is primarily due to procyclical overtime payments incurred beca use employment is not perfectly flexible in most industries output price fails to respond to the cyclical movement in marginal cost so price marginal cost margins are markedly countercyclical the res ults contradict business cycle theories that explain low production i n a recession by a high real cost of producing they support theories that explain low production in a recession by the inability of firms to sell their output copyright 1987 by american economic association

dynamic factor demands and the effects of energy price shocks a dynamic model is used to understand how sharp changes in energy prices affect investment behavior employment and energy use the authors discuss the theory behind their model selection model specifications estimation methods and data list parameter estimates and elasticities for the selected model and describe the simulations they conclude that 1 the data strongly reject the hypothesis of constant returns to scale within their specification of aggregate production 2 the data indicate adjustment costs on labor are small and 3 their results help reconcile some of the conflicting estimates of energy demand elasticities appearing in recent literature 23 references 3 figures 3 tables

joint pricing and inventory policies for make to stock products with deterministic price sensitive demand abstract in this paper we focus on a firm selling a single make to stock product to price sensitive end customers we develop an integrated operations marketing model that can help determine the relevant profit maximizing decision variable values for two pricing policies that the firm might follow price as a decision variable which is advocated by academicians and mark up pricing used by most practitioners we first consider an eoq based model with price and order quantity as independent decision variables we then develop an analogous model where price is a mark up over operating costs per unit and order quantity becomes the sole decision variable we are able to ascertain the optimal decision variable values for each model for log linear and linear demand functions we prove that for such profit maximizing models the optimal batch size is not necessarily monotone increasing in set up cost interestingly our numerical analytical evidence suggests that from a profit perspective it is better for managers to be aggressive on price rather than reducing price too much especially for highly price sensitive and non linear demand moreover we establish that in general the profit penalty for not including inventory costs in determining the optimal batch size or ignoring the batch size optimization issue in a mark up price model is not significant only when the set up cost is quite high and or the firm faces non linear demand from highly price sensitive end consumers does it become crucial for managers to determine the exact optimal batch size and base the mark up price on the entire unit operating cost not only the unit variable production cost

identification of endogenous social effects the reflection problem this paper examines the reflection problem that arises when a researcher observing the distribution of behaviour in a population tries to infer whether the average behaviour in some group influences the behaviour of the individuals that comprise the group it is found that inference is not possible unless the researcher has prior information specifying the compisition of reference groups if this information is available the prospects for inference depend critically on the population relationship between the variables defining reference groups and those directly affecting outcomes inference is difficult to implossible if these variables are functionally dependent or are statistically independent the prospects are better if the variables defining reference groups and those directly affecting outcomes are moderately related in the population

search method use by unemployed youth this article presents a search model which shows that search method choices should be related to their costs and expected productivities as well as to nonwage income and wage offer distributions the empirical evidence then shows that the most frequently used search methods i e friends and relatives and direct applications without referral are also the most productive in generating offers and acceptances the number of methods used is affected by factors that presumably reflect opportunities as well as income sources and needs specific methods are chosen in a manner that generates positive average effects on outcomes for those using them

monetary rules for small open emerging economies abstract this paper develops a variant of the imf s global economic model suitable to analyze macroeconomic dynamics in open economies and uses it to assess the effectiveness of taylor rules and inflation forecast based ifb rules in stabilizing variability in output and inflation our findings suggest that a simple ifb rule that does not rely upon any direct estimates of the equilibrium real interest rate and places a relatively high weight on the inflation forecast may perform better in small open economies than conventional taylor rules

markups in u s and japanese manufacturing a short run econometric analysis in this article a production theory based model of firms markup behavior is constructed the theoretical structure is based on variants of generalized leontief cost and expenditure functions this framework yields a specification of behavior from which the impacts of both supply and demand shocks on firms markup behavior can be assessed through elasticities adjustment costs on both labor and capital and economies of scale are incorporated estimation is carried out using manufacturing data for the united states and japan from 1960 through 1981 the empirical results suggest that markups for manufacturing firms in both the united states and japan have increased over time but have somewhat different cyclical characteristics stemming primarily from differential investment behavior in addition capacity utilization and especially returns to scale tend to counteract the short run profit potential from markup behavior so that markups measured assuming constant returns are typically biased downward finally

social networks employee selection and labor market outcomes we provide a direct empirical test of montgomery s 1991 notion that firms hire workers through social ties of productive employees as these workers know others with high unobserved productivity we focus on coworker networks and show that firms recruit workers with better military draft test scores but shorter schooling when hiring previous colleagues of current employees suggesting that firms use these networks to attract workers with better qualities in hard to observe dimensions incumbent workers abilities predict the incidence abilities and wages of linked entrants these results suggest that firms rely on the ability density of the studied networks when setting entry wages

unraveling the productivity growth slowdown in the u s canada and japan the effects of subequilibrium scale economies and markup measures of productivity growth typically include in the productivity residual the impacts of fixity of factors subequilibrium costs of adjustment returns to scale and markups this paper proposes a general framework for adjusting the residual to accommodate these impacts by first correcting and then decomposing traditional measures use of the framework is illustrated empirically for the united states japanese and canadian manufacturing sectors using an econometric model that allows explicit incorporation and measurement of these factors the adjusted measures show that a significant amount of cyclical and secular change in measured productivity growth can be attributed to production characteristics other than technical change particularly scale effects copyright 1992 by mit press
