incentives productivity and labor contracts the relationship between age earnings profiles and worker incentives is examined by contrasting wage and salary workers with the self employed it is argued that the steepness of wage and salary workers age earnings profiles reflects the desire to provide work incentives to those workers since self employed workers do not face this agency problem they are used as a benchmark to gauge productivity empirical support of the proposition is provided and the effects of human capital accumulation are separated empirically from incentive effects the most important conclusion is that under some strong assumptions most of the slope in age earnings profiles is accounted for by the desire to provide incentives rather than by on the job training

multidimensional mechanism design for auctions with externalities abstract in an auction with externalities a buyer s type is multidimensional and specifies the payoff he would get for each of the n 1 possible outcomes the seller keeps the object or buyer i i 1 n gets the object we provide a characterization of multidimensional incentive compatible mechanisms similar to that for one dimensional mechanisms although reservation utilities are endogenous and type dependent the participation constraint is binding for only one critical type a main difficulty in a multidimensional setting is the integrability condition we present a geometric characterization for discontinuous conservative vector fields in auctions where the buyers submit scalar bids and the seller transfers the object to one of the buyers for sure a second price auction maximizes revenue with two buyers this auction remains optimal even if the seller can set a reservation price journal of economic literature classification numbers c7 c72

education and contraceptive choice a conditional demand framework a multiperiod model of fertility and contraceptive choice which considers unobserved differential preferences for the timing of births is formulated conventional and conditional demand equations for contraceptives are derived from the model and the relationships in each between female education birth intentions and the level of contraceptive efficiency are compared demand equations derived from the model conditioned on birth intentions were shown to be superior to conventional demand equations in testing some of the assumptions pertaining to the technology of contraceptives embedded in the utility maximization framework a weak test of the hypothesis that education lowers the fixed costs of information associated with new technologies as exemplified by the oral contraceptive was shown to be obtainable only from consistent estimates of conditional contraceptive choice demand parameters as a consequence of the dual technological attributes of contraceptive methods if education affects both the costs of children and preference orderings over the spacing of births the education contraceptive use association conditional on the number of intended children cannot be used to make welfare comparisons across households the log linear model in which contraceptives were categorized on the basis of their cost characteristics and simulatenous equations techniques were used to obtain estimates of the conditional demand equations for contraceptives based on data from the national fertility survey 1970 estimates indicated that the education of the wife among households with identical fertility plans was significantly and positively associated with the adoption of the newer birth control methods in 1970 with quantitiative affects significantly greater than those indicated in reduced form and inconsistently estimated conditional equations appearing in a priori studies the results support the hypothesis that the relative magnitudes of fixed and variable contraceptive costs influence contraceptive decisions with the value of the wifes time an important component of the former and suggest that women with higher levels of education are more likely to use traditional contraceptive methods

a mechanism design approach to ranking asymmetric auctions i propose a new mechanism design approach to the problem of ranking standard auctions with two heterogeneous bidders a key feature of the approach is that it may be possible to rank two auctions even if neither dominates the other for all combinations of types the approach simplifies the analysis and unifies results in the existing literature roughly speaking the first price auction is more profitable than the second price auction when the strong bidder s distribution is flatter and more disperse than the weak bidder s distribution applications include auctions with one sided externalities moreover contrary to previous work reserve prices are easily handled finally the method can be extended to some environments with many bidders

technological change and retirement decisions of older workers according to human capital theory technological change will influence the retirement decisions of older workers in two ways first workers in industries with high rates of technological change will retire later if there is a net positive correlation between technological change and on the job training second an unexpected change in the rate of technological change will induce older workers to retire sooner because the required amount of retraining will be an unattractive investment we matched industry data on productivity growth and occupational data on required training with data from the national longitudinal surveys of older men to test these hypotheses our results support both hypotheses

are those paid more really more productive the case of experience this study uses computerized personnel microdata on the white male managerial and professional employees at a major u s corporation to address the following question can the additional earnings which are associated with more labor market experience at a point in time really be explained by higher productivity at the same point in time our answer to this question based on both cross sectional and longitudinal information is that performance plays a substantially smaller role in explaining cross sectional experience earnings differentials and earnings growth than is claimed by those who have adopted the human capital explanation of the experience earnings profile this response depends critically on our assumption that the performance ratings which supervisors give to their white male managerial and professional subordinates adequately reflect the subordinates relative productivity in the year of assessment we present a great deal of evidence which strongly supports this assumption

determinants of child mortality health and nutrition in a developing country abstract child health and nutrition status are important determinants of adult productivities and earnings and thus are an important channel of intergenerational socioeconomic mobility building upon economic models of household behavior we investigate the determinants of child mortality and health and nutrition status in regions defined by the degree of urbanization in the developing country of nicaragua and offer some policy suggestions our estimates suggest that determinants differ significantly across regions income is not an important factor there is an inverse relation with number of siblings and there are positive associations with calorie intake schooling except in the relatively low income rural areas the availability of refrigeration and the quality of sewage systems

a switching regression model for wage determinants in the public and private sectors of a developing country governments in less developed countries face severe budgetary constraints given that public sector employment is a large part of modern sector employment the government wage bill h as come under increased scrutiny the central question is how do gove rnment wages compare with those in the private sector in this paper the authors develop and estimate a model to answer this question an important aspect of this model is the endogenous treatment of sector choice the estimation results full information maximum likelihood sound a strong warning against the use of ordinary least squares est imates that are based on sector specific samples data are from the i vory coast copyright 1988 by mit press

the demand for education for home production this paper analyzes a type of education thus far ignored in the literature non credit adult education to enhance home production skills in the analysis we test whether such education behaves as an investment in home productivity and also compare the differences between demands for home productivity enhancing education and labor market enhancing education results on four adult cohorts indicate that both types of schooling have investment components although there are also significant differences in the two demand functions results also indicate that the two types of education are complementary rather than substitute activities

optimal wage taxation when human capital and employment are endogenous this paper studies how optimal wage tax conclusions from the classic two period life cycle model of human capital accumulation are affected by endogenizing the number of taxpaying workers in the absence of a corrective policy young individuals underinvest in human capital from a social perspective because tax premiums for transfers to nonworkers are not actuarially adjusted downward for human capital attainment a combination of wage taxes and wage subsidies can restore proper price signals numerical simulations suggest that even modest employment elasticities can be sufficient to substantially impact the magnitudes and even the signs of optimal wage tax rates jel h21 h3 j24

education and freedom of choice evidence from arranged marriages in vietnam abstractusing household data from vietnam we provide evidence on the effects of education on freedom of spouse choice we use war disruptions and spatial indicators of schooling supply as instruments the point estimates indicate that a year of additional schooling reduces the probability of an arranged marriage by about 14 percentage points for an individual with eight years of schooling we also estimate bounds on the effect of education on arranged marriage when exclusion restrictions are violated locally the lower bound is six to seven percentage points the impact of education is strong for women but significantly weaker for men

life expectancy and human capital investments evidence from maternal mortality declines longer life expectancy should encourage human capital accumulation since a longer time horizon increases the value of investments that pay out over time previous work has been unable to determine the empirical importance of this life expectancy effect due to the difficulty of isolating it from other effects of health on education we examine a sudden drop in maternal mortality risk in sri lanka between 1946 and 1953 which creates a sharp increase in life expectancy for school age girls without contemporaneous effects on health and which also allows for the use of boys as a control group using additional geographic variation we find that the 70 reduction in maternal mortality risk over the sample period increased female life expectancy at age 15 by 4 1 female literacy by 2 5 and female years of education by 4 0 authors

the consumption value of schooling an empirical estimate of one aspect the purpose of this paper is to demonstrate by example that human capital is more than just a capital good in the strictest sense of the term certain forms of human capital have consumption value in addition to the value of the increased stream offuture monetary and nonmonetary benefits a methodfor empirically estimating the consumption value of schooling as a vehicle to avoid the vietnam war draft is presented

on the analysis of asymmetric first price auctions we provide a new set of tools for studying asymmetric rst price auctions connecting their equilibria to the concavity of the underlying type distributions and showing how one can use surplus expressions related to symmetric auctions to bound equilibrium behavior in asymmetric auctions we apply these tools to studying procurement auctions in which as is common in practice one seller is given an advantage re ecting for example better reliability or quality we show conditions under which for any given rst price handicap auction there is a second price auction with bonuses that outperforms it with most of our results involving ex post dominance

termination restrictions and investment in general training abstract conditional separation payments efficiently increase firms investment in general training if the latter is not directly contractible since training is vested in the worker on separation a firm s return to training is zero when a match ends or more generally when the firm s outside return is binding large enough conditional separation penalties ensure that independently from outside opportunities the ex post situation is one of bilateral monopoly this allows the firm to capture a positive share of the return to the general component of training in all states of nature a fixed wage contract and large enough separation penalties ensure that the firm s investment decision is fully efficient if training is general in becker s 1964 sense

optimal bidding in auctions from a game theory perspective abstract the game theoretic perspective in auction bidding has provided a powerful normative framework for the analysis of auctions and it has generated an impressive volume of research contributions tracing this research we review key recent advances which have greatly expanded our understanding of the operation of auctions and produced a more accurate analysis of mechanism design and optimal bidding we follow various experimental studies which have shown that the predictive power of auction theory remains in many cases limited for this reason we concentrate on research themes which enhance the applicability of auction theory leading to more realistic descriptions of bidding behaviors we identify important innovations which expand the environment of auction bidding and carry us beyond rational decision making we conclude providing directions of future research and discussing their implications

an economic model of teaching effectiveness the literature on the determinants of good teaching performance has been largely devoted to empirical measurement a complete review of the publications in this area would require at least an entire issue the size of this journal yet it is virtually impossible to discover attempts to derive hypotheses about the determinants of good teaching from explicit models of behavior this has led researchers into the trap of exploring only the empirical determinants of good teaching performance typically the results of student evaluations are correlated with affective personality traits of the teachers with peer evaluations of psychological compositions or even with the results of various psychological tests examples are the works of robert isaacson et al frank costin et al and wilbert mckeachie et al in most of these studies no substantive conclusions are reached regarding the determinants of effective teaching in the few studies which do contain significant findings the independent variable in question is difficult to explain as a direct determinant of teaching effectiveness for example isaacson et al find that virtually the only statistically significant determinant of effective teaching is the personality characteristic which they label culture this may imply that simply wearing a tweed jacket and taking up pipesmoking is sufficient to improve teaching this paper takes a somewhat different approach to the analysis of teaching assume that the individual in question wishes to maximize teaching effectiveness clearly there are constraints on this maximization process one must necessarily be the time budget constraint a second constraint however adds a good deal of interest to the model this constraint is best described as the bundle of characteristics available to the individual these characteristics could be termed the components of the individual s personality such attributes include physical appearance psychological makeup speaking ability and a myriad of other variables thus this model bears a resemblance to the standard economic models of monopolistic competition see a michael spence before proceeding to a formal statement of the problem a philosophical issue must be addressed what is meant by teaching effectiveness generally this is interpreted as maximizing student evaluations of teachers however this is clearly not always equivalent to maximizing student learning unfortunately the latter variable is difficult but not impossible to measure preand posttesting with standardized tests is becoming increasingly accepted for example the meaning of teaching effectiveness in this paper must unfortunately remain ambiguous some teachers concerned perhaps with obtaining tenure will interpret good teaching as obtaining good evaluations the criterion by which they are judged others may take a more eclectic viewpoint since the problem below is an individual maximization problem the precise definition of effective teaching may simply vary from individual to individual see w r allen formally this problem is exactly analogous to one first addressed by kelvin lancaster he assumes that the consumer attempts to maximize satisfaction through purchase of bundles of attributes each commodity is possessed of certain of these characteristics by consuming various combinations of these commodities the consumer is assistant professor department of economics and director center for economic education california state university hayward i would like to thank alex cassuto nancy sanders and an anonymous referee for helpful discussion in a previously unreported experiment in the department of economics california state universitybakersfield faculty members were required to wear coats and ties in classes it was subsequently observed that teaching evaluations improved unfortunately no detailed statistical results of this experiment are available for analysis

who is behavioral cognitive ability and anomalous preferences in this paper we ask whether variation in preference anomalies is related to variation in cognitive ability evidence from a new laboratory study of chilean high school students with similar schooling backgrounds shows that small stakes risk aversion and short run discounting are less common among those with higher standardized test scores the relationship with test scores survives controls for parental education and wealth we find some evidence that elementary school gpa is predictive of preferences measured at the end of high school two laboratory interventions provide suggestive evidence of a possible causal impact of cognitive resources on expressed preferences jel j24 d14 c91

production and innovation when techniques are tacit the case of education abstract the central theme of this paper is that the conventional economic theory of production does not hold even approximately in a field like education after examining the result of input output studies in education and the effect of government attempts to enhance education effectiveness we provide a sketch of a new production theory for sectors where techniques are poorly articulated and idiosyncratic

modeling multiple outputs in educational production functions for some time now economists have conceptualized learning as a production process most educational production functions specify only one output usually a measure of cognitive achievement some recent studies have recognized the multidimensional aspects of schooling specifying outputs in both the cognitive and affective domains introducing multiple outputs into the production function raises interesting theoretical and empirical issues one issue is the manner in which various outputs are interrelated how one models output interactions in educational production functions may be important are the outputs multiple products if so are they independently or simultaneously produced or are the outputs joint products answers to these questions may affect empirical estimates of the educational production function s this paper briefly describes how one might approach this problem we argue on conceptual grounds that modeling outputs in the cognitive and affective domains as joint products is preferable in addition we compare the three approaches empirically to evaluate the sensitivity of educational production function parameter estimates to output specification

favoritism in asymmetric contests head starts and handicaps abstract i examine a contest with identity dependent rules in which contestants are privately informed and ex ante heterogeneous a contestant may suffer from a handicap or benefit from a head start the former reduces the contestant s score by a fixed percentage the latter is an additive bonus although total effort increases if the weak contestant is favored with a head start the optimal use of handicaps is not as clear cut depending on the nature of the asymmetry it may or may not be optimal to handicap the strong contestant moreover it is generally optimal to combine the two instruments for instance when contestants are sufficiently heterogeneous the weak contestant should be given both a head start and a handicap it may also be possible to induce higher effort and at the same time make both contestants better off ex ante

schooling and economic well being the role of nonmarket effects standard estimates of the economic value of additional schooling based on earnings differences associated with differences in the level of schooling attained cover only a portion of the total effects of education that are valued by citizens we first identify a catalog of nonmarketed effects many of which have been recently studied by economists and then propose a procedure for estimating a willingness to pay value for these effects using empirical estimates of the magnitude of a selection of these effects found in the literature we calculate willingness to pay values using our proposed procedure these illustrative calculations suggest that standard estimates of the benefit of incremental schooling substantially understate the full value of such investments

asymmetric first price auctions abstract a new approach to asymmetric first price auctions is proposed which circumvents the need to examine bidding strategies directly specifically the ratio of bidders endogenous payoffs is analyzed and compared to the ratio of the exogenous distribution functions that describe beliefs most of the results are inferred from this comparison in the existing theoretical literature assumptions of first order stochastic dominance or stronger imply that the latter ratio has very specific properties but no such assumptions are imposed here it is proven that first order stochastic dominance is necessary for bidding strategies not to cross when this assumption is relaxed in the numerical literature it is done in a manner that leads to exactly one crossing however it is straightforward to construct examples with several crossings finally bid distributions will cross in auctions with two bidders whenever second order but not first order stochastic dominance applies

numerical analysis of asymmetric first price auctions abstract we propose numerical algorithms for solving first price auction problems where bidders draw independent valuations from heterogeneous distributions the heterogeneity analyzed in this work is what might naturally emerge when subsets of distributionally homogeneous bidders collude bid functions and expected revenues are calculated for two special cases extensions to more general asymmetric first price auctions are discussed journal of economic literature classification numbers d44 c63 c72 d82

the impact of human capital investments on pension benefits this article develops a model with deferred compensation and severance pay that predicts that workers bear all the costs and receive all the returns of human capital investments and that specific investments yield higher returns than general investments this model also predicts that pensions which efficiently defer compensation will be positively related to specific investments evidence from the national longitudinal survey of older men confirms these predictions participation in company sponsored training programs proxying for specific investments increases the probability of pension receipt and the level of benefits more general training outside the firm has much smaller effects on pensions

the economics of schooling production and efficiency in public schools n recent years public and professional interest in schools has been heightened by a spate of reports many of them critical of current school policy these policy documents have added to persistent and long standing concerns about the cost effectiveness and fairness of the current school structure and have made schooling once again a serious public issue as in the past however any renewed interest in education is likely to be short lived doomed to dissipate as frustration over the inability of policy to improve school practice sets in this frustration about school policy relates directly to knowledge about the educational production process and in turn to underlying research on schools although the educational process has been extensively researched clear policy prescriptions flowing from this research have been difficult to derive 2 there exists however a consistency to the research findings that does have an immediate application to school policy schools differ dramatically in quality

estimating a firm s age productivity profile using the present value of workers earnings in hiring new workers risk neutral employers equate the present expected value of each worker s compensation to the present expected value of his her productivity data detailing how present expected compensation varies with the age of hire embed therefore information about how productivity varies with age this paper infers age productivity profiles using data on the present expected value of earnings of new hires of a fortune 1000 firm for each of the five occupation sex groups considered productivity falls with age with productivity exceeding earnings for young workers and vice versa for older workers

ability tracking school competition and the distribution of educational benefits abstract to study the effects of ability grouping on school competition we develop a theoretical and computational model of tracking in public and private schools we examine tracking s consequences for the allocation of students of differing abilities and income within and between public and private schools private schools tend to attract the most able and wealthiest students and rarely track in equilibrium public sector schools can maximize attendance by tracking students public schools retain a greater proportion of higher ability students by tracking but lose more wealthy lower ability students to the private sector consequently socioeconomic status is a predictor of track assignment in public schools for the entire population public sector tracking has small aggregate effects on achievement and welfare but results in significant redistribution from lower to higher ability students

gender and ethnicity differentials in school attainment and labor market earnings in ecuador summary indigenous people in ecuador are most likely to be disadvantaged and live in poverty this paper reports on the findings of an econometric analysis which explores the extent to which lower educational attainment and labor market discrimination contribute to these disparities the analysis utilizes a proportional hazard regression model to examine which factors raise the probability of early school departure it also employs a classic regression model to explore the relationship between low educational attainment and earnings together with an oaxaca decomposition which parses out the extent to which earning differentials can be attributed to differences in human capital or to discrimination

the economic consequences of brain drain of the best and brightest microeconomic evidence from five countries this article presents results of innovative surveys that tracked academic high achievers from five countries to wherever they moved in the world to directly measure at the micro level the channels through which high skilled emigration affects sending countries there are high levels of emigration and of return and the income gains to the best and brightest from migrating are an order of magnitude greater than any other effect most high skilled migrants from poorer countries remit but involvement in trade and foreign direct investment is rare fiscal costs vary widely but are much less than the benefits to the migrants themselves two narratives drive discussions of the development impact of high skilled migration the first is the idea of a brain drain whereby the departure of doctors teachers engineers scientists and other highly skilled workers decimates the human capital and fiscal revenues of sending countries bhagwati and hamada 1974 such fears lead to calls for policies to restrict the flow of highly skilled workers such as demands that developed countries stop recruiting doctors from developing nations and efforts by developing nations to restrict the ease of their highly skilled individuals migrating 1 contrasting with this is the view of a highly educated diaspora as a potent force for developing the local economy through remittances trade foreign direct investment fdi and knowledge transfers with the experience of india and china in setting up technology firms as a result of diaspora working in silicon valley a prominent example saxenian 2002 economists have also emphasised that the possibility of migrating may spur human capital accumulation potentially leading to a net increase in the education levels of those in the home country 2

labor market shocks and retirement do government programs matter abstract this paper argues that labor market conditions are an important and often overlooked determinant of retirement transitions in our analysis we examine how the unemployment rate affects retirement and whether the social security ss system and unemployment insurance ui system influence how older workers respond to labor market shocks we use pooled cross sectional data from the march current population survey cps in our analysis we find that downturns in the labor market increase retirement transitions and that the magnitude of this effect is comparable to that associated with moderate changes in financial incentives to retire and to the threat of a health shock facing older workers interestingly retirements only increase in response to an economic downturn once workers become ss eligible suggesting that retirement benefits may help to alleviate the income loss associated with a weak labor market we also estimate the impact of ui generosity on retirement and find little consistent evidence of an effect this suggests that in some ways ss may serve as a more effective form of unemployment insurance for older workers than ui

human capital accumulation and the expansion of women s economic rights abstractbetween 1850 and 1920 most u s states enacted laws expanding the rights of married women to own and control their separate property and to own their market earnings the economic approach to property rights implies that as married women gain economic rights the incentive to invest in girls human capital will rise this prediction is tested by examining the impact of these legal changes on girls school attendance rates relative to boys state level census data are used to examine the effects of these changes on school attendance among all school aged children integrated public use microdata series data are used to examine their effect on school attendance among children ages 15 19 who are just beyond compulsory schooling ages consistent with hypothesized effects the empirical analysis shows that expanding women s economic rights resulted in higher relative rates of school attendance by girls and had the largest effect on the 15 19 age group

paying for good neighbours estimating the value of an implied educated community by definition spillovers across households in residential communities mean that people incur costs from living in neighbourhoods where a high proportion of households suffer deprivation regardless of their own economic circumstances to verify the existence of intracommunity spillovers this paper shows that home owners in england and wales are prepared to pay a substantial premium to avoid educationally poor neighbourhoods an increase of 1 per cent in the proportion of higher educated residents in a community relative to the regional mean increases prices by 0 24 per cent one interpretation of this educational elasticity is that it estimates the social benefits of education in the local community a hedonic approach is used paying careful attention to the endogeneity of neighbourhood characteristics in a property price model

health and wage a simultaneous equation model with multiple discrete indicators in this article we propose all econometric approach for estimating the simultaneouls effects of health and wages in a structural equations framework in the theoretical works of grossmana 1972a 1972b health is viewed as anl elldogen1oulsly determined capital stock the demand for health should rise with the wage rate as the rate of return to health investment increases with wage onl the other hand better health should raise market productivity and hence wages since health capital is an abstract theoretical concept it can hardly be measured quantitatively however most population surveys include various health indicators these indicators are usually discrete variables in the empirical work of grossman and benham 1974 these qualitative indicators are treated as continuous variables and two stage least squares estimation techniques are used this specification raises various econometric problems see e g goldberger 1964 pp 248 255 domencich and mcfadden 1975 and nerlove and press 1973 a satisfactory specification should take into account the discrete nature of the indicators our specification generalizes the dummy variables simultaneous equations system of heckman 1978 the measurement models of joreskog and goldberger 1975 and is closely related to the models of muthe n 1976 1979 muthen studies full information maximum likelihood procedures for estimation except for very simple cases this does not generally yield feasible or tractable procedures in this article we introduce a tractable procedure for statistical estimation and testing this specification and the estimation procedure is then applied to study the joint dependence of health and wages another departure of our approach from others is that we will test and correct the possible incompatibility of the various health capital indicators in the population surveys one may have subjective health indicators such as self evaluation of health which may reflect different populations perception of health we propose a statistical procedure for testing measurement compatibility and if required for correcting this problem this article is divided into two parts initially we describe the model specification estimation and statistical tests in a general simultaneous equation model with multiple discrete indicators in the second part of the paper we consider specification of a simultaneous equation model for health and wages the model

parental altruism and child lead exposure inferences from the demand for chelation therapy we use parents decisions to treat their children s body burdens of lead to infer parental ex ante willingness to pay for reduced burdens willingness to pay is estimated with a data set containing 256 observations the data were originally gathered to assess the impact of children s body lead burdens upon their intellectual and behavioral development our results indicate that parental ex ante willingness to pay for a 1 percent reduction in child body lead burden exceeds the estimated ex post savings in medical treatment and compensatory education costs caused by the same reduction

pricing in a supply chain for auction bidding under information asymmetry abstract we examine a supply chain in which a manufacturer participates in a sealed bid lowest price procurement auction through a distributor this form of supply chain is common when a manufacturer is active in an overseas market without establishing a local subsidiary to gain a strategic advantage in the division of profit the manufacturer and distributor may intentionally conceal information about the underlying cost distribution of the competition in this environment of information asymmetry we determine the equilibrium mark up the ex ante expected mark up and expected profit of the manufacturer and the equilibrium bid of the distributor in unilateral communication we demonstrate the informed agent s advantage resulting to higher mark up under information sharing we show that profit is equally shared among the supply chain partners and we explicitly derive the mark up when the underlying cost distribution is uniform in 0 1 the model and findings are illustrated by a numerical example

multidimensional welfare distributions empirical application to household panel data from vietnam this article explores the empirical application of theoretical multidimensional welfare distribution analysis techniques to real household welfare distributions the article operationalizes recent conceptual developments in multidimensional distribution theory and assesses their usefulness for the measurement of multidimensional household inequality the results strongly highlight the importance of bringing nonmonetary aspects of household welfare into the forefront of inequality analysis agreement over the various approaches to the measurement of multidimensional inequality entails however nontrivial decisions that may limit the practical usefulness of these measures we suggest that the use of multidimensional inequality ranges and the application of restrictive dominance criteria to multidimensional welfare distributions may open significant scope for further developments in the empirical analysis of multidimensional inequality

bulls bears and retirement behavior the authors examine the relationship between stock market performance and retirement behavior they first present a descriptive analysis of the wealth holdings of older households and simulate the labor supply response among stockholders necessary to generate observed retirement patterns few house holds they find have substantial stock holdings and these holdings would have to be extremely responsive to market fluctuations to explain observed labor force patterns the authors then exploit stock market fluctuations since the early 1980s particularly the boom and bust between 1995 and 2002 along with variation in stock exposure to generate a double quasi experiment comparing the retirement and labor force re entry patterns over time of those more and less exposed to the market any difference in behavior that emerged during the boom should have reversed itself during the bust the authors find no evidence that changes in the stock market drove aggregate trends in labor supply

future social security entitlements and the retirement decision abstract a critical question for social security policy is how program incentives affect retirement behavior we use the health and retirement survey hrs to examine the impact of social security incentives on male retirement we implement forward looking models whereby individuals consider the incentives to work in all future years we find that forward looking incentive measures for social security are significant determinants of retirement we also find that private pension incentives have roughly similar effects our findings suggest that social security policies that increase the incentives to work at older ages can significantly reduce the labor force exit rate of older workers

asymmetric auctions with resale we study first and second price auctions with resale in a model with indepen dent private values with asymmetric bidders the resulting inefficiencies create a motive for post auction trade which in our model takes place via monopoly pricing the winner makes a take it or leave it offer to the loser we show a a first price auction with resale has a unique monotonic equilibrium and b with resale the expected revenue from a first price auction exceeds that from a second price auction the inclusion of resale possibilities thus permits a gen eral revenue ranking of the two auctions that is not available when these are excluded jel d44

the relevance of standard estimates of rates of return to schooling for education policy a critical assessment abstract this paper examines the accuracy and usefulness of estimated rates of return to schooling based on the standard human capital model of becker and mincer regarding accuracy it investigates whether failure to account for differences in ability and school quality lead to significant biases estimates using ghanaian data confirm this possibility even when accurate estimated rates of return to additional years of schooling may have limited policy implications more useful for governments are rates of return to investments in school quality the paper uses data on cognitive skills to estimate rates of return to three types of school quality improvements

women work and weil being in the middle east an outline of the relevant literature there is now an extensive literature on the role of women in economic development and the impact of development on their lives this article concentrates on the economic literature and discusses its importance for policies aimed at working women in the middle east it identifies the important strands and places the discussion within the wider context of women in the labour market in both developing and developed countries the general conclusion is that we are very far from having sufficient knowledge to implement effective policy or even to evaluate existing policies

the effort maximizing contest with heterogeneous prizes we establish the effort maximizing rule of allocating heterogeneous prizes when contestants privately observe their effort efficiencies with ex ante symmetric players and increasing virtual effort efficiency an all pay auction maximizes the total expected effort

training and retirement patterns life cycle theory predicts that employers enter into implicit contracts with newly hired employees to ensure rent sharing and to decrease turnover after firm specific training investments typically these implicit contracts would include both upward sloping earning profiles and mandatory retirement in this article we empirically test the prediction that workers with firm specific skills are restrained in their options to continue working therefore they are more likely to retire at common mandatory retirement dates than those with general skills using the us national longitudinal survey of older men we find that workers who participated in firm specific training in their early careers do indeed retire earlier than those with general skills the results show that compulsory retirement plans force these older workers to retire when they reach the common mandatory retirement age of 65 the results presented in this article are highly relevant for public policies in european and other industrialized cou

on the contract curve a test of alternative models of collective bargaining the traditional model of collective bargaining confines unions to settlements constrained by the employer s labor demand curve but an alternative model places wage employment outcomes on a contract curve that extends beyond the labor demand curve this paper derives a multidimensional hedonic contract curve model in which employment security provisions are used to maintain efficient bargains outside the employer s demand curve and distinguishes empirically between the contract curve and demand constraint models using data for public school teachers in new york state estimates clearly support the contract curve model over the demand constraint model by linking the gap between compensation and the value of the marginal product to the strength of employment security provisions

asymmetric first price menu auctions under intricate uncertainty abstract this paper studies asymmetric first price menu auctions in the procurement environment where the buyer does not commit to a decision rule and asymmetric sellers have interdependent costs and statistically affiliated signals sellers compete in bidding a menu of contracts where a contract specifies a vector of characteristics and a payment required from the buyer for delivering these characteristics the buyer does not commit ex ante to a decision rule but rather upon observing all the menus offered by sellers chooses the best contract this paper establishes the existence of a continuum of separating monotone equilibria in this game bounded above by the jointly ex post efficient outcome and below by the jointly interim efficient outcome it shows that the jointly ex post efficient equilibrium outcome is the only ex post renegotiation proof outcome and it is also ex ante robust to all continuation equilibria

the quality of schooling quantity alone is misleading although much research discusses the quantity of schooling as an effective impact on productivity and earnings most such research leaves out the idea of the quality of schooling which may cause biases in the estimated returns to schooling this paper consequently attempts to extend the standard mincerian approach to incorporate school quality as well as quantity it demonstrates how exclusion of quality in the standard procedure may cause biases in the estimated returns to years of schooling probably in the upward direction the paper explores the implications of this extension of the standard model for the case of young brazilian males it shows that the estimate of the private return to years of schooling using the preferred quality inclusive specification is only one half the estimate using the standard procedure indicating substantial upward bias in the standard estimates it further outlines a method for estimating a social return to quality and finds that it exceeds substantially the social return to quantity the paper then shows why this in turn suggests there may be an equity productivity trade off in schooling investments

cost and income based measures of human capital human capital is increasingly believed to play an important role in the growth process however adequately measuring its stock remains controversial in this paper three general approaches to measurement are identified cost based income based and educational stock based this survey focuses on the first two approaches and provides a critical review of the theories and their applications to data from a range of countries particular emphasis is placed upon the work of jorgenson and fraumeni 1989 1992 and some new results for new zealand based upon their approach are also presented
