learning and wage dynamics we develop a dynamic model of learning about worker ability in a competitive labor market the model produces three testable implications regarding wage dynamics 1 although the role of schooling in the labor market s inference process declines as performance observations accumulate the estimated effect of schooling on the level of wages is independent of labor market experience 2 timeinvariant variables correlated with ability but unobserved by employers such as certain test scores are increasingly correlated with wages as experience increases and 3 wage residuals are a martingale we present evidence from the nlsy that is broadly consistent with the model s predictions

parameter estimates comparison of earnings functions in the psid and cps data 1976 2007 comparing earnings equations in the panel study of income dynamics psid and the current population survey we find that the psid considerably underestimates the returns to education during the 1992 2007 period non random selection in the psid sample appears to be the reason

compensatory inter vivos gifts parents transfer motives are important for understanding e g macroeconomics income re distribution savings and public finance using data from six biennial waves of the health and retirement study 1992 2002 we estimate censored regression models with nested multilevel error components first we interpret our findings that inter vivos transfers from parents to children are gifts rather than temporary help to overcome liquidity constraints second inter vivos gifts are compensatory in the sense that lifetime poorer children will receive higher transfers than their lifetime richer siblings third inter vivos gifts do not however make up the entire difference in lifetime incomes copyright 2009 john wiley sons ltd

institutional ownership of stock and dimensions of corporate social performance an empirical examination collectively institutions own an increasing proportion of outstanding corporate equities as an emergent force in shaping corporate america the linkages between institutional ownership and corporate social performance csp require empirical examination not only do corporate policy makers need to know those areas where social performance may lure or inhibit capital infusions lawmakers also need a better understanding of the social forces guiding corporate policy as anticipated this study found a positive relationship between the amount of institutional ownership of corporate stock and a company s social responsiveness as measured by the representation of women on its board of directors however no statistically significant relationship with social responsibility as measured by charitable giving was found the exemplar of social issues management compliance with the sullivan principles showed an unexpected negative relationship with the level of institutional ownership

is the correlation in welfare participation across generations spurious abstract this paper asks whether the observed correlation in welfare participation across generations reflects causal links or unobservables that are correlated across generations if the correlation is spurious then reducing one generations welfare participations will have no effect on the next generation the panel study of income dynamics is used to estimate two types of models that explicitly take account of correlated unobservables these models indicate that correlated unobservables are important in explaining the intergenerational correlation in welfare participation among blacks but not non blacks however the correlation across generations continues to be significant for blacks even after taking account of the correlated unobservables

health shocks and natural resource management evidence from western kenya poverty and altered planning horizons brought on by the hiv aids epidemic can change individual discount rates altering incentives to conserve natural resources using longitudinal household survey data from western kenya we estimate the effects of health status on investments in soil quality as indicated by households agricultural land fallowing decisions we first show that this effect is theoretically ambiguous while health improvements lower discount rates and thus increase incentives to conserve natural resources they also increase labor productivity and make it more likely that households can engage in labor intensive resource extraction activities we find that household size and composition are predictors of whether the effect of health improvements on discount rates dominates the productivity effect or vice versa since households with more and younger members are better able to reallocate labor to cope with productivity shocks the discount rate effect dominates for these households and health improvements lead to greater levels of conservation in smaller families with less substitutable labor the productivity effect dominates and health improvements lead to greater environmental degradation

the effects of school spending on educational and economic outcomes evidence from school finance reforms since the coleman report many have questioned whether public school spending affects student outcomes the school finance reforms that began in the early 1970s and accelerated in the 1980s caused dramatic changes to the structure of k 12 education spending in the united states to study the effect of these school finance reform induced changes in public school spending on long run adult outcomes we link school spending and school finance reform data to detailed nationally representative data on children born between 1955 and 1985 and followed through 2011 we use the timing of the passage of court mandated reforms and their associated type of funding formula change as exogenous shifters of school spending and we compare the adult outcomes of cohorts that were differentially exposed to school finance reforms depending on place and year of birth event study and instrumental variable models reveal that a 10 increase in per pupil spending each year for all 12 years of public school leads to 0 31 more completed years of education about 7 higher wages and a 3 2 percentage point reduction in the annual incidence of adult poverty effects are much more pronounced for children from low income families exogenous spending increases were associated with notable improvements in measured school inputs including reductions in student to teacher ratios increases in teacher salaries and longer school years jel codes j10 i20 h7

promotions and wage growth this article presents evidence that internal mobility defined as a promotion or other position change is an important source of wage growth it accounts for approximately 15 of wage growth over the life cycle for white and black men but less for women the incidence of promotions and other position changes appears tied to the wage level better paid workers are more likely to be promoted the life cycle incidence of internal mobility looks similar to that for conventionally defined job mobility most moves are made early in the career mobility declines both with time in position and with experience

a theory of wage and promotion dynamics inside firms we show that a framework that integrates job assignment human capital acquisition and learning captures several empirical findings concerning wage and promotion dynamics inside firms including the following first real wage decreases are not rare but demotions are second wage increases are serially correlated third promotions are associated with large wage increases fourth wage increases at promotion are small relative to the difference between average wages across levels of the job ladder fifth workers who receive large wage increases early in their stay at one level of the job ladder are promoted quickly to the next

testing for asymmetric employer learning recent evidence suggests that employers acquire more precise information about a worker s productivity the more time he or she spends in the labor market the following question arises is learning symmetric that is do all employers have the same information about workers productivity or is learning asymmetric that is does the current employer have superior information about workers productivity this article develops a learning model with endogenous mobility that nests both learning hypotheses it then proposes new tests for asymmetric employer learning overall learning appears to be mostly symmetric except possibly when the employees involved are college graduates

expenditure response to increases in in kind transfers evidence from the supplemental nutrition assistance program recent studies on food stamp participant households marginal propensity to spend out of food stamps versus income have had contradictory results experimental studies have found household behavior aligns with standard economic theory where households marginal propensity to spend on food out of food stamps is equivalent to cash income observational studies nd that households have a larger marginal propensity to spend out of food stamps than cash income in this study we re examine this question by estimating how an unprecedentedly large increase in food stamp benets due to the implementation of the american recovery and reinvestment act aects food at home expenditure we nd that the policy change caused households to increase food at home expenditure as well as increase households share of total expenditure allocated toward food at home expenditure we compare these results to a time period without a meaningful food stamp policy change and nd our results are unique to the arra implementation time period

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

team performance and race evidence from the english and french national soccer teams this study examines the performance of the men s senior national soccer teams of england and france between the years 1996 and 2011 the paper models team performance using an array of match specific variables including the racial composition of the starting eleven we find no definitive evidence that the racial composition of the national teams exerts an influence on match outcome for either country over the period reviewed in addition while there is no statistical support for the view that the identity of the england national team manager is an important determinant of performance there is mild evidence that the converse is the case for france

factors influencing the profitability of fertilizer use on maize in zambia major findings the additional maize produced from a given amount of fertilizer applied varied widely across households even after largely controlling for soil and rainfall conditions the median estimated response rate was 15 9kgs of maize per kg nitrogen applied under the range of conditions and smallholder management practices average maizefertilizer response rates declined as the application rate increased beyond 2 bags of urea and 2 bags of d compound factors raising the response rate and profitability of fertilizer use included timely availability application rates less than the moa 4x4 recommendation use of animal draft power in land preparation and use of hybrid seed in remote areas and given current management practices fertilizer use appears to be profitable only for a minority of smallholder farmers in the relatively remote areas for farmers in the more accessible areas profitability of fertilizer use depends on timely availability if fertilizer is not available on time even farmers in the more accessible parts of this area of relatively high agronomic suitability for maize production are largely unable to use fertilizer profitably because over 30 percent of the households reported that fertilizer was delivered late these findings indicate that efforts to ensure timely distribution can contribute substantially to the productivity gains achievable from fertilizer use

fortunate sons new estimates of intergenerational mobility in the united states using social security earnings data previous studies relying on short term averages of fathers earnings have estimated the intergenerational elasticity ige in earnings to be approximately 0 4 due to persistent transitory fluctuations these estimates have been biased down by approximately 30 or more using administrative data containing the earnings histories of parents and children the ige is estimated to be around 0 6 this suggests that the united states is substantially less mobile than previous research indicated estimates of intergenerational mobility are significantly lower for families with little or no wealth offering empirical support for theoretical models that predict differences due to borrowing constraints

the effects of benefit timing and income fungibility on food purchasing decisions among supplemental nutrition assistance program households the supplemental nutrition assistance program snap is the largest nutritional safety net in the united states prior research has found that participants have higher consumption shortly after receiving their benefits followed by lower consumption towards the end of the benefit month known as the snap benefit cycle this consumption pattern has been found to have negative effects on beneficiaries we hypothesize two behavioral responses of snap participants may work in tandem to drive much of the cycle 1 short run impatience a higher preference to consume today and 2 fungibility of income the degree of substitutability between a snap dollar and a cash dollar using data from the national food acquisition and purchase survey foodaps a newly developed nationally representative survey of daily food acquisitions by snap households we find evidence of both behavioral responses however the degree of short run impatience and fungibility of income is found to differ significantly across poverty levels and use of grocery lists to plan food purchases snap households could gain from food purchase planning education

job duration seniority and earnings an important stylized fact about labor markets is that workers with longer seniority with their current employer have higher earnings than other workers with the same total labor market experience this study shows that workers in longer jobs earn more throughout than workers in a series of shorter jobs and that the measured positive cross sectional return seniority is largely a statistical artifact due to the correlation of seniority with an omitted variable representing the quality of the worker the job or the worker employer match the implication is tha t earnings do not in fact rise very much with seniority copyright 1987 by american economic association

do labor market opportunities affect young women s work and family decisions experimental evidence from india do labor market opportunities for women affect marriage and fertility decisions we provided three years of recruiting services to help young women in randomly selected rural indian villages get jobs in the business process outsourcing industry because the industry was so new at the time of the study there was almost no awareness of these jobs allowing us in effect to exogenously increase women s labor force opportunities from the perspective of rural households we find that young women in treatment villages were significantly less likely to get married or have children during this period choosing instead to enter the labor market or obtain more schooling or postschool training women also report wanting to have fewer children and to work more steadily throughout their lifetime consistent with increased aspirations for a career copyright 2012 oxford university press

land reallocation in an agrarian transition liberalising key factor markets is a crucial step in the transition from a socialist control economy to a market economy however the process can be stalled by imperfect information high transaction costs and covert resistance from entrenched interests the article studies agricultural land reallocation in the wake of vietnam s efforts to establish a free market in land use rights following de collectivisation inefficiencies in the initial administrative allocation are measured against an explicit counterfactual land allocation responded positively but slowly to the initial inefficiencies there is no sign that the transition favoured the land rich or that it was thwarted by local officials vietnam s agrarian transition has closely followed a now classic policy scenario for economies in transition first one privatises the main productive assets in this case agricultural land use rights then one legalises their free exchange in the first step the de collectivisation of vietnam s agriculture meant that the land that had previously been farmed collectively was to be allocated by administrative means across households within each commune without a market mechanism to guide the process it can be expected that inefficiencies in land allocation would remain with some households having too much land relative to a competitive market allocation and some too little ravallion and van de walle 2004 document evidence of such inefficiencies in the initial administrative allocation at the time of de collectivisation

structural estimation of family labor supply with taxes estimating a continuous hours model using a direct utility specification this paper proposes a new method for estimating family labor supply in the presence of taxes this method accounts for continuous hours choices measurement error unobserved heterogeneity in tastes for work the nonlinear form of the tax code and fixed costs of work in one comprehensive specification estimated on data from the 2001 psid the resulting elasticities for married males are consistent with those found elsewhere in the literature but female wage elasticities are substantially smaller than those found in most of the literature simulations of recent tax acts predict small effects on the labor supply of married couples

does money matter for intergenerational income transmission the intergenerational income elasticity iie is a crucial measure of income mobility in this article we develop a structural model to examine the channels through which this elasticity operates using data from the panel study of income dynamics we separately identify the human capital and the financial components the human capital component examines the transmission of human capital independent of financial investments whereas the financial component examines the impact of income that is uncorrelated with human capital that is exogenous income using a two stage framework we show that the iie operates through both channels moreover our estimates show that the financial component may have a larger effect than previously estimated plausibly attributing to 36 of intergenerational income transmission indeed this result holds even when the financial component is defined in an incredibly narrow manner this suggests that cash payments could promote intergenerational mobility

assisting the transition from workfare to work a randomized experiment randomly sampled workfare participants in a welfare dependent region of argentina were given a voucher that entitled an employer to a sizable wage subsidy a second sample also received the option of skill training while a third sample formed the control group the authors analyze the effects of this scheme on participants employment and income using double difference and instrumental variables methods to deal with potential experimental biases including selective compliance with the randomized assignment the authors find that compared with the control group voucher recipients had a significantly higher probability of employment though their current incomes were no higher the impact was largely confined to women and younger workers labor supply effects appear to have been important however training had no significant impact the experiment was cost effective in reducing the government s welfare spending since take up of the subsidy by employers was low

the internal economics of the firm evidence from personnel data we analyze twenty years of personnel data from one firm the hierarchical structure is quite simple and stable career movements suggest that the employee s rate of learning and the firm s learning about ability are important there are promotion fast tracks exit rates vary little with tenure or salary the firm has personnel policies like those described in the internal labor markets literature although several theoretical preconditions for ilms such as ports of entry and exit are lacking job levels are important to compensation but there is also substantial individual variation in pay within levels our companion paper in this issue explores the wage policy of this firm

wage growth and job mobility in the united kingdom and germany using data from the british household panel survey for 1991 99 and the german socio economic panel for 1984 99 the authors investigate job mobility and estimate the returns to tenure and experience job mobility was higher in the united kingdom than in germany returns to experience also seem to have been substantially higher in the united kingdom where the wage gain associated with ten years of labor market experience was around 80 compared to 35 in germany the low returns to labor market experience in germany appear to have been accountable to one group of workers those with apprenticeship training who tended to receive fairly high starting wages but to experience relatively low wage growth thereafter wage growth due to labor market experience was similar between the two countries for the other skill groups returns to tenure were close to zero in both countries

an analysis of the impact of sample attrition on the second generation of respondents in the michigan panel study of income dynamics only a few studies have tried to estimate the trend in the elasticity of children s economic status with respect to parents economic status and these studies produce conflicting results in an attempt to reconcile these findings we use the panel study

the sports business as a labor market laboratory with superior data on compensation and productivity as well as the occurrence of abrupt dramatic market structure and player allocation rules changes sports labor markets offer an excellent setting in which to test economic hypotheses this paper reviews evidence from sports in four areas employer monopsony discrimination the coase theorem and incentive contracts supervision and performance there is considerable evidence of monopsony as well as for the existence of some forms of discrimination against minority athletes incentive contracts have strong effects on player performance and behavior and there is mixed evidence on the predictions of the coase theorem

the impact of bolsa familia on schooling summary we use longitudinal household data and propensity score weighting methods to assess the impact of brazil s bolsa familia conditional cash transfer program on schooling outcomes of children aged 6 17 years weak aggregate effects mask considerable heterogeneity among girls the program significantly increases school participation by 8 percentage points and grade progression by 10 percentage points with large significant effects across both younger and older girls in rural areas but concentrated among girls aged 15 17 years in urban areas few significant impacts are found among boys we discuss implications and potential mechanisms for differential impacts by sex age and location

talent and or popularity what does it take to be a superstar the phenomenon of superstars wherein small numbers of people earn enormous amounts of money and dominate the activities in which they engage seems to be increasingly important in the modern world rosen 1981 845 i introduction this the opening sentence of sherwin rosen s seminal paper the economics of superstars applies today more than ever technological change has increased the scope and the intensity of the so called winner takes all markets in the last decades the central question addressed in this article is what does it take to be a superstar why do some artists media stars professional athletes or executives earn disproportionately high salaries while others receive comparatively low remuneration in the literature there are basically two competing but not mutually exclusive theories of superstar formation proposed by rosen 1981 and adler 1985 1 although sherwin rosen explains how small differences in talent translate into large differences in earnings moshe adler argues that superstars might even emerge among equally talented performers due to the positive network externalities of popularity empirical tests of the different driving forces of superstar salaries have proved to be very difficult because an objective measure of a star s talent is often hard to find and even harder to quantify krueger 2005 for example what characterizes the talent of a pop music star the literature offers different approaches hamlen 1991 1994 uses the physical concept of voice quality which measures the frequency of harmonic content that singers use when they sing the word love in one of their songs but is such a high quality voice really a deciding factor for success in pop music krueger 2005 measures star quality by the number of millimeters of print columns devoted to each artist in the rolling stone encyclopedia of rock roll nevertheless as he admits this measure reflects the subjective importance the editors of the encyclopedia implicitly devote to each artist which may correlate both with the artist s talent and with his her popularity in team settings the difficulty of accurately measuring star talent is even greater as individual contributions to team output are mostly unclear however the empirical relevance of stars within teams is undoubted star ceos in top management teams lead singers of rock bands and star athletes on sports teams are just a few examples of superstars embedded in teams this article argues that rank order tournaments in professional sports allow a more accurate determination of talent than in the arts even though each athlete s performance is also affected by random events luck or other factors like weak fitness in individual sports it can typically be assumed that the most talented athlete enjoys the highest probability of winning as we examine superstars in a team setting namely in professional soccer we first estimate a team production function to identify the playing characteristics that significantly influence the probability of a team winning to do so we use the detailed statistics of the opta sports data company which counts and classifies every touch of the ball during the game by each player in a second step we use the individual performance statistics of all variables that have proved to be critical for winning as indicators of the player s talent we estimate the impact of talent popularity and various controls on the player s market value employing individual panel data from the highest german soccer league a player s popularity is measured by the annual press publicity he receives in over 20 different newspapers and magazines purged of the positive influences of on field performance so that our popularity indicator captures the nonperformance related celebrity status of a player we find empirical evidence that both talent and nonperformance related popularity increase the market values of soccer stars

promotions demotions halo effects and the earnings dynamics of american executives this paper explores the determinants of earnings growth in corporate hierarchies using static and dynamic panel data techniques the novelty derives from the distinction between base pay and bonus the asymmetric effects of promotion and demotion and the consideration of dynamic effects we find that the convexity of pay structures is robust to the allowance for unobserved individual heterogeneity demotion has a stronger effect on compensation growth in absolute value than promotion dynamic models indicate that the causal effect of past promotion is positive on the growth in base and total pay but has no significant effect on bonus growth

a longitudinal analysis of sibling correlations in economic status numerous previous studies have used sibling correlations to measure the importance of family background as a determinant of economic status the sibling correlations estimated in these studies however have been depressed by a failure to distinguish transitory and permanent income variation and in some cases by overly homogeneous samples this paper presents a methodology to address these problems and applies it to longitudinal data from the panel study of income dynamics our main conclusion is that family background exerts greater influence on economic status than has been indicated by most earlier research

promotion turnover and compensation in the executive labor market this paper develops a generalized roy model with human capital accumulation moral hazard and career concerns we identify and estimate the model with a large panel that matches data on publicly listed firms to information on their executives the structural estimates obtained are used to decompose the firm size pay gap we find that although total compensation and incentive pay increase with firm size certainty equivalent pay decreases with firm size in larger firms and for more highly ranked executives weaker signal quality about effort results in higher risk premiums this risk premium accounts for roughly 80 percent of the firm size gap in total compensation larger firms are also willing to pay more than smaller ones to attract executives finally the estimated coefficients on human capital accumulation from formal education and experience gained from different firms are individually significant but their collective effect on firm size pay differentials nets out

food stamps and food spending an engel function approach estimation of food stamp program fsp effects has been complicated by self selection and by a contradiction between observed spending patterns and the economic theory of consumer choice we developed a modified version of the traditional theory in which participant households may be partly extramarginal even if they have some cash spending on at home food using current population survey cps data for 2001 2005 we estimated engel functions for at home and away from home food spending for fsp participants and nonparticipants compared to nonparticipants with the same level of total income participants had higher at home food spending and lower away from home food spending copyright 2007 oxford university press

team effects on compensation an application to salary determination in the national hockey league leo h kahane studies of salary determination largely model pay as a function of the attributes of the individual and the workplace i e employer size job characteristics and so forth this article empirically investigates an additional factor that may influence individual pay specifically coworker productivity data from professional sports are used to evaluate this question because both salary and teammate performance measures are readily available we find that team attributes have both direct effects on an individual s pay and indirect effects through altering the rates at which individual player productive characteristics are valued jel j31 l83 i introduction when complementary exists between labor inputs individual productivity may be poorly measured by treating the individual worker separately from the character of the organization or team within which he works namely individual productivity may vary when working in different settings to the extent that coworkers offer different degrees of assistance 1 if such complementary between human capital inputs is present say a team dynamic it suggests the possible existence of both team and individual effects on productivity and hence compensation empirical analysis of team effects has been hindered by the lack of data on individuals and their coworkers including managers one source though that contains much of this requisite information is data on professional sports teams in this article we exploit this unique attribute of professional sports data in order to empirically assess the effect of complementarities between labor inputs on individual compensation specifically we use a team sport setting to situate the worker in an organizational environment where we can observe the impact of coworkers on individual productivity thereby allowing us to examine the separate effects of individual and team productivity on salary determination the general question asked is whether individual attributes are valued or rewarded differently in different work environments or in our specific case on different teams this study will investigate these questions by empirically assessing the effects of coworker productivity that is the effects of the qual ity productivity of teammates on individual compensation although a number of different highly team oriented sports would serve our purpose such as basketball this particular study uses data from professional hockey to investigate team effects on compensation 2 the remainder of the article is organized as follows section ii outlines the empirical framework used to analyze the posited team effects and discusses some of the theoretical issues relating to team effects on compensation section iii describes the data used in the analysis section iv reports the empirical results and section v reports our conclusions and directions for further work ii team and coworker effects as noted above the goal of this study is to evaluate empirically whether average coworker attributes 1 affect individual salaries 2 affect the rate at which individual attributes are valued by the firm and 3 are complementary inputs to the attributes of individual team members the question arises though as to why we might expect on theoretical grounds that individual players would earn any part of the team s contribution the classic model of alchian and demsetz 1972 suggests that the capitalist manager will reap the returns from any incremental team output as the primary function of the manager is to discover complementarities between inputs and enhance organizational output by optimally combining resources and to monitor effort so as to reduce shirking as a result the manager will capture all of the returns that are not specific to the inputs in which case we would not expect to observe team effects on individual compensation yet although a manager acting as the residual claimant is one solution to the problem of reducing shirking in the context of complementary inputs whose effort is difficult to monitor other models suggest that it may be desirable to compensate team members based on the value of team output in order to provide optimal incentives for effort for example see akerlof 1982

an analysis of sample attrition in panel data the michigan panel study of income dynamics by 1989 the michigan panel study on income dynamics psid had experienced approximately 50 percent sample loss from cumulative attrition from its initial 1968 membership we study the effect of this attrition on the unconditional distributions of several socioeconomic variables and on the estimates of several sets of regression coefficients we provide a statistical framework for conducting tests for attrition bias that draws a sharp distinction between selection on unobservables and on observables and that shows that weighted least squares can generate consistent parameter estimates when selection is based on observables even when they are endogenous our empirical analysis shows that attrition is highly selective and is concentrated among lower socioeconomic status individuals we also show that attrition is concentrated among those with more unstable earnings marriage and migration histories nevertheless we find that these variables explain very little of the attrition in the sample and that the selection that occurs is moderated by regression to the mean effects from selection on transitory components that fade over time consequently despite the large amount of attrition we find no strong evidence that attrition has seriously distorted the representativeness of the psid through 1989 and considerable evidence that its cross sectional representativeness has remained roughly intact

the effect of wage dispersion on team outcome and the way team outcome is produced the impact of intra team pay dispersion on team productivity is a highly discussed issue on the one hand wage differentials provide incentives for higher employee effort on the other hand pay inequality may reduce team cohesiveness and increase feelings of relative deprivation leading to lower performance analysing nonlinear effects of wage dispersion in professional soccer we find empirical evidence that team performance is strongest when there is either very high or very low wage inequality medium levels produce the weakest team performance in addition we show that the pay structure affects the team s playing style even after controlling for team and coach heterogeneity we discuss the theoretical and managerial implications as well as the limits of generalization

enriching a theory of wage and promotion dynamics inside firms in previous work we showed that a model that integrates job assignment human capital acquisition and learning can explain several empirical findings concerning wage and promotion dynamics inside firms in this article we extend that model in two ways first we incorporate schooling and derive further testable implications that we then compare with the available empirical evidence second and more important we show that introducing task specific human capital allows us to produce cohort effects we further argue that task specific human capital is a realistic concept and may have many important implications we also discuss limitations of our extended approach
