off budget activities of local government reply take issue with this conclusion for a number of reasons first professor blewett is correct in stating that debt financing of capital expenditures may provide a better matching of intertemporal benefits and costs thereby contributing to greater efficiency but in the case of obes this is not fully applicable for obes issue debt to finance capital and operating expenses and even commit the double sin of issuing debt to pay off previous debt as is the case with new york state s municipal assistance corporation in fact as pointed out in our article obes are used to evade civil service restrictions and to expand public sector employment and wages in short obes are a mechanism used to engage in deficit finance although it is true that they also finance capital projects projects which in many instances have not obtained voter approval with respect to the issue of accountability and voter control it is of course true that the traditional public choice approach holds that competing governments can provide advantages in terms of both consumption and production efficiency but careful consideration of the particular institutional arrangements of obes indicates that they do not fit into this mold if one views politics as a dynamic process as professor blewett in citing buchanan suggests then it is clear that one should not expect greater accountability from obes than from general purpose units of government for as discussed in our paper economic history reveals that they are and have been created with precisely the intent to thwart the wishes of voters not to accommodate them and to provide politicians and bureaucrats with patronage opportunities which would not otherwise have

interrupted work careers depreciation and restoration of human capital the quantitative effects and even the existence of a human capital depreciation phenomenon have been a subject of controversy in the recent literature prior work however was largely cross sectional and the longitudinal dimension if any was retrospective using longitudinal panel data on married women in nls we have now established that real wages at reentry are indeed lower than at the point of labor force withdrawal and the decline in wages is greater the longer the interruption another striking finding is a relatively rapid growth in wages after the return to work this rapid growth appears to reflect the restoration or repair of previously eroded human capital the phenomenon of depreciation and restoration is also visible in data for immigrants to the united states however while immigrants eventually catch up with and often surpass natives returnees from the nonmarket do not fully restore their earnings potential

risk preferences are not time preferences balancing on a budget line comment in a recent experimental study of intertemporal risky decision making andreoni and sprenger 2012 find that subjects exhibit a preference for intertemporal diversification which is inconsistent with discounted expected utility theory it was claimed that their results are also at odds with models involving probability weighting such as rank dependent utility and cumulative prospect theory here we demonstrate however that rank dependent probability weighting explains intertemporal diversification if decision makers care about portfolio risk moreover we provide a unified account of all of andreoni and sprenger s key findings

intermittent work activity and earnings patterns of intermittent work activity appear to be more common in the modern labour market at least for younger workers this study extends earlier models of the relationship between labour market intermittency and earnings to include both part time work and nonparticipation to differentiate between past work experience and current job tenure to allow for nonlinear experience effects and to account for selection bias arising from the exclusion of nonworkers the results suggest that the effects of part time work and nonparticipation on earnings are similar moreover some common patterns emerge the effects are larger for women greater for young workers and greater when intermittency replaces current job tenure

instant gratification temporal discounting and self employment differences in temporal discounting could separate self employed individuals from employees working for wages drawing on a sample of 13 198 individuals from the 2012 2013 cross sectional step skills measurement survey we find that higher temporal discounting is more positively associated with the likelihood of self employment we further find that younger individuals with higher temporal discounting are more likely to engage in self employment the association of lower socioeconomic status at a young age or those who experienced economic shocks at a young age with the likelihood of self employment is only significant when interaction effects of temporal discounting and age are present in the model risk seeking is not associated with the likelihood of engagement in self employment under higher discounting these findings have implications for the self employment literature as well as the literature on behavioral decision making

gender differences in training capital and wages this paper constructs an equilibrium job matching model where workers differ in their attachment to the labor force the model predicts that workers with weaker attachment to the labor market will receive lower starting wages and lower post training wages and will be placed in jobs that offer less training and use less capital the implications of the model for gender differences in pay and job assignment are tested with the eopp data set ourfindings suggest that while training intensity during the first three months of employment is similar in positions filled by males and females females are employed in positions that have a shorter duration of on the job training and that use less capital these differences in on the job training and capital in positions filled by men and women as well as a lower market value for women s prior labor market experience account for a substantial part of the gap in wages between males and females

a search interpretation of male female wage differentials a general equilibrium search framework is used to examine the role of gender differences in labor market behavior patterns e g quit rates for personal reasons in determining gender wage differentials for samples of high school and college graduates from the national longitudinal survey of youth nlsy these behavioral patterns are found to be significantly different across the sexes and account for 20 30 of the wage differentials in particular they play a key role in explaining the male female wage differential that remains after controlling for the gender composition across occupations

valuing lost home production of dual earner couples using a life cycle model in which women divide their time between home and market work we establish a link between retirement wealth and the value of forgone home production we use data from the health and retirement study to estimate the model s parameters and adjust the growth rate of gdp to reflect reductions in non market output we find that the value of forgone home production is modest about 25 percent of women s measured earnings

social motives vs social influence an experiment on interdependent time preferences we report experimental evidence on the effects of social preferences on intertemporal decisions to this aim we design an intertemporal dictator game to test whether dictators modify their discounting behavior when their own decision is imposed on their matched recipients we run four different treatments to identify the effect of payoffs externalities from those related to information and beliefs our descriptive statistics show that heterogeneous social time preferences and information about others time preferences are significant determinants of choices dictators display a marked propensity to account for the intertemporal preferences of recipients both in the presence of externalities social motives and or when they know about the decisions of their matched partners social influence we also perform a structural estimation exercise to control for heterogeneity in risk attitudes as for individual behavior our estimates confirm previous studies in that high risk aversion is associated with low discounting as for social behavior we find that social motives outweigh social influence especially when we restrict our sample to pairs of dictators and recipients who satisfy minimal consistency conditions

childbearing decision making and family well being a dynamic sequential model first birth most affected by current family income and living standards the hypothesis that the consequences of each additional birth vary depending on initial family size is strongly supported the strongest consequences are felt by families with no children or only one child initially and the impact declines with parity support for the hypothesis that the outcomes associated with each birth are causal factors at the next decision point in a sequential model could not be found in this analysis thus the evidence for the usefulness of such a model is mixed social and behavioral scientists increasingly believe that fertility decisions are made simultaneously with other family choices a couple decides how many children to have how much time and money to invest in each and how much time to allocate to market work housework and leisure an increase in the wife s labor force participation for example leaves her less time for child care and the family may have to purchase substitute care the couple also decides how to divide total expenditures among competing market goods and services and what proportion of total family income to save this process is further complicated by evidence that these choices may not be made once and for all but change as circumstances and experience dictate it is assumed that individuals have at least an implicit understanding of the trade offs they are making and that these

risk preferences are not time preferences on the elicitation of time preference under conditions of risk comment andreoni and sprenger 2012a b report evidence that distinct utility functions govern choices under certainty and risk i investigate the robustness of this result to the experimental design i find that the effect disappears completely when a multiple price list instrument is used instead of a convex time budget design alternatively the effect is reduced by half when sooner and later payment risks are realized using a single lottery instead of two independent lotteries the result is thus at least partially driven by intertemporal diversification supporting an explanation in terms of concavity of the intertemporal and not only atemporal utility function jel c91 d81 d91

ambiguity aversion and comparative ignorance decisions under uncertainty depend not only on the degree of uncertainty but also on its source as illustrated by ellsberg s observation of ambiguity aversion in this article we propose the comparative ignorance hypothesis according to which ambiguity aversion is produced by a comparison with less ambiguous events or with more knowledgeable individuals this hypothesis is supported in a series of studies showing that ambiguity aversion present in a comparative context in which a person evaluates both clear and vague prospects seems to disappear in a noncomparative context in which a person evaluates only one of these prospects in isolation

married womens tastes and the decision to participate in the labour market results from a fixed effects model in the paper we report estimates from two logit models of women s labour force participation a model with out fixed effects estimated from cross sectional data indicates a significant postive relation between work experience and particiption we ask whether the relation is due to a causal influence extered by the former variable on the latter or to a common underlying variable taste for market attachement to answer this question we present results from a fixed effects model estimated from panel data in this model the estimated coefficients of experience are insignificant suggestion that a taste for market attachement underlies both experience and participation is the presence of preschool children

the effects of job relocation on spousal careers evidence from military change of station moves we investigate the impact of military job relocation on spousal earnings and employment by creating a unique longitudinal database that tracks over 900 000 military spouses over the period 2001 2012 based on data from two administrative sources military records on personnel and their dependents and social security earnings records this database allows us to estimate the effects of military change of station moves controlling for some key observable characteristics of the service member and household and controlling for individual spouse fixed effects we find that military moves cause a substantial decline in spousal earnings in the year of the move on the order of 2 100 or 14 of average spousal earnings moves also increase the likelihood that the spouse has no earnings for the year we find larger earnings reductions for moves that cross state lines and for older spouses male spouses and those with young children the career costs persist over time and spouses continue to experience significantly lower earnings 2 years after the move this persistence combined with the typical military member experiencing a change of station move every 2 or 3 years may substantially limit the ability of military spouses to accumulate human capital over time jel h56 r23 j45 j16 j64

taxation and household labor supply we evaluate reforms to the u s tax system in a life cycle setup with heterogeneous married and single households and with an operative extensive margin in labor supply we restrict our model with observations on gender and skill premia labor force participation of married females across skill groups children and the structure of marital sorting we concentrate on two revenue neutral tax reforms a proportional income tax and a reform in which married individuals flle taxes separately separate flling our flndings indicate that tax reforms are accompanied by large increases in labor supply that difier across demographic groups with the bulk of the increase coming from married females under a proportional income tax reform married females account for more than 50 of the changes in hours across steady states while under separate flling reform married females account for all the change in hours

welfare regimes family supportive policies and women s employment along the life course this article examines women s employment patterns during thechild rearing period and the consequences of those patterns for earnings later in life in 12 industralized countries this study proposes an analytic framework that combines welfare regime and gender specific policies to explain country differences the findings presented here suggest that institutional arrangements mediate the costs to women s part time and intermittent employment within welfare regimes employment continuity is highest among countries in which the state provides support for working mothers furthermore this study finds that lower support for mothers employment is associated with higher wage penalties to employment discontinuity

memory and discounting theory and evidence abstract heterogeneous memory capacity is largely neglected in the economics literature although it may have profound economic implications adopting the concept of memory utility proposed by gilboa postlewaite and samuelson 2016 we explore the relationship between memory capacity and individual discounting behavior by building a simple two period model and comparing its predictions with experimental data both theoretical and experimental evidence confirm that memory capacity and discount rates are positively correlated

is there one unifying concept of utility an experimental comparison of utility under risk and utility over time the nature of utility is controversial whereas decision theory commonly assumes that utility is context specific applied and empirical decision analysis typically assumes one unifying concept of utility applicable to all decision problems this controversy has hardly been addressed empirically because of the absence of methods to measure utility outside the context of risk we introduce a method to measure utility over time and compare utility under risk and utility over time we distinguish between gains and losses and also measure loss aversion in two experiments we found that utility under risk and utility over time differed and were uncorrelated utility under risk was more curved than utility over time subjects were loss averse both for risk and for time but loss aversion was more pronounced for risk loss aversion over risk and time were uncorrelated this suggests that loss aversion although important in both decision contexts is volatile and subject to framing

identification of supplier induced demand in the health care sector this paper explores the issues and pitfalls encountered when attempting to test empirically the hypothesis that physician hospital or any other input supply level induces increasing demand for health services in the strict sense of demand shift and through that increased demand for the input in question evidence is presented which suggests that an empirical test of the supplier induced demand sid hypothesis of the type traditionally performed may not in fact be feasible with cross sectional aggregate data such as is usually used

learning by doing and investment in training a synthesis of two rival models of the life cycle this paper provides a theoretical synthesis of recent discussions of learning by doing and investment in training as alternative forms of human capital accumulation these theoretical notions relate to essentially different phenomena in particular pace becker and mincer investment in training does not completely encompass learning by doing the paper then develops a model in which human capital accumulation occurs via both training and learning by doing the joint training learning model since it is more general then pure models in which all accumulation occurs via either training or learning avoids certain restrictive and seemingly implausible implications of either kind of pure model however the joint model also has implications that while compatible with stylized facts about the life cycle are sharper than those of either kind of pure model for example the joint model implies that market time and earnings must rise early in the life cycle while neither pure model without corners does so finally the notion of learning by doing provides a rationale for an empirical finding that has recently received attention to the effect that the rate of depreciation of human capital is not constant but rather depends on the extent to which it is used in market activities

the gender gap in early career wage growth in the uk the gender pay gap on entry to the labour market is approximately zero but ten years after labour market entry there is a gender wage gap of almost 25 log points this article explores the reason for this gender gap in early career wage growth considering three main hypotheses human capital job shopping and psychological theories human capital factors can explain about 11 log points job shopping about 1 5 log points and the psychological theories up to 4 5 log points depending on the specification but a substantial unexplained gap remains women who have continuous full time employment have had no children and express no desire to have them earn about 8 log points less than equivalent men after 10 years in the labour market

individual and opportunity factors influencing job creation in new firms we build on multiple theoretical perspectives to investigate the unique and joint effects of individual and opportunity level factors affecting job creation in new firms we tested hypotheses using survey data from individuals who transitioned from unemployment to self employment under the auspices of a german public policy program our findings reveal that an entrepreneur s breadth of knowledge has a negative influence on the firm s job creation whereas the entrepreneur s leadership experience has a positive influence however as the sector specific labor requirements of a business opportunity increase both breadth of knowledge and leadership experience allow founders to operate their firms with fewer employees

postponing maternity in ireland as in many other developed countries ireland has experienced a postponement of maternity whilst a number of authors have commented on this trend suggesting greater female participation in the workforce results in delayed maternity to date little research has tested this proposition we develop a model to consider the main trends related to the phenomenon of maternity postponement considering changes in first and later births separately using retrospective life history data developed from the 1994 living in ireland survey we estimate a hazard model to empirically test the relationship between career planning and the timing of first and subsequent births we incorporate a declining marginal return to experience and thereby provide a human capital career planning explanation for maternity postponement the results of our analysis demonstrate that career planning has an impact on the timing of maternity the findings also establish an income effect that influences the timing of first births copyright the author 2010 published by oxford university press on behalf of the cambridge political economy society all rights reserved oxford university press

early career work experience and gender wage differentials we estimate a wage model that includes an array of variables measuring the fraction of time worked during each year of the career this array fully characterizes past employment experience regardless of how sporadic it has been our model yields substantially higher estimated returns to experience and lower returns to tenure than do models that measure experience cumulatively and use the standard quadratic functional form we find that the data reject the standard model but fail to reject our model furthermore we find that 12 of the male female wage gap is due to differences in the timing of work experience

the effects of interrupted schooling on wages data from the national longitudinal survey of youth reveal that 35 percent of white men who leave school between 1979 and 1988 return to school by 1989 this paper examines the wage effects of these nontraditional enrollment patterns i estimate a wage model which allows individuals to follow a different wage path before and after their reenrollment and an alternative model which does not account for school and work discontinuities i find that young men who delay their schooling receive wage boosts that are smaller than those received by their continuously schooled counterparts wage models that fail to account for delayed schooling tend to understate the returns to schooling received prior to the start of the career

the gender gap in earnings at career entry we propose a new approach to analyzing gender differences in wages this approach identifies several alternative explanatory mechanisms to account for the sorting of women and men into different types of jobs that offer different levels of reward because labor market rewards derive from labor market positions we study matching processes operating at the micro level that sort workers into existing slots in a given macro level structure of jobs and associated wages we focus on the explanation of gender differences in wages at career entry analyzing data from the national longitudinal survey of youth collected between 1979 and 1991 we find that at career entry women earn 84 cents for every dollar men earn gender differences in worker characteristics account for only about 30 percent of this wage gap gender differences in occupational aspirations have the most important effect accounting for 16 percent of the wage gap and gender differences in job related skills and credentials account for about 14 percent of the wage gap gender differences in adult family roles have little direct effect our analysis further suggests that the external influences of employing organizations and network processes on gender differences in occupational and industrial placement at career entry account for another 42 percent of the wage gap t is well established that in the united states on average women s wages are lower than those of men data on the 1992 annual earnings of full time year round workers ages 16 and older indicate that on average women earned 71 cents for every dollar earned by men u s bureau of the census 1993 we analyze gender differences in wages at career entry when market con

convex time budgets and individual discount rates in the long run the purpose of this study is to use experimental data to estimate individual discount rates and test for hyperbolic discounting over a long time horizon to do this we employ the convex time budget experimental approach with cash payments over a 20 year time horizon to date there are few experimental studies that explore discount rates beyond a 1 year time horizon previous experimental studies that focus on short time horizons find high discount rates which may not be applicable to decisions that affect outcomes in the distant future our findings are quite similar to the average rate of 4 9 found by grijalva et al environ resour econ 59 39 63 2014 who similarly use a 20 year time horizon but use the multiple price list elicitation method along with payment via government savings bonds we find annual discounts rates in the range of 1 9 5 5 depending on the specific model used we also find evidence for declining discount rates and that this hyperbolic pattern of behavior is related to the confidence subjects have in receiving distant future payments

off budget activities of local government comment bennett and dilorenzo have provided evidence that limitations on taxes and spending induce a proliferation of special purpose local government they conclude that the effects on spending were less than originally supposed whatever the effects on total spending a very important effect on the limitations is an induced change in the fiscal constitution of local government using a public choice approach this institutional change was found to have certain desirable features

the gap between male and female pay in the spanish tourism industry abstract this paper analyzes wage differentials between male and female workers in the spanish tourism industry using a large administratively matched employer employee data set obtained from a representative sample of companies this allows us to control for unobserved firm specific factors likely to affect the magnitude of the gender wage gap our findings indicate that male workers earn on average 6 7 higher monthly wages than their socially comparable female counterparts in particular the type of contract held the qualifications required for the job and the specific sub sector of employment are very important variables in explaining this gender wage difference we also find that only around 12 of the mean wage difference in the tourism industry cannot be explained by differences in observable characteristics which is well below the average for the rest of the industries in spain 87 our interpretation is that minimum wage legislation provides a particularly effective protection to women in the tourism industry which is characterized by a large number of low wage earners

investment and interruption effects of the us experience on the earnings of return migrants in mexico migration is widely viewed as an investment in human capital however due to the imperfect transferability of skills and knowledge across countries migration trips are also career interruptions especially for return migrants who may meanwhile experience depreciation of home country specific skills this article demonstrates that migration experience increases return migrants earnings in the home country on the condition that the migration stay is sufficiently long and mostly uninterrupted employing the revised human capital earnings function the empirical study shows that only a barely interrupted us experience longer than five years regardless of the legal status of the migration trips predicts higher earnings of male return migrants in mexico than comparable non migrants robust findings emerge controlling for unobserved individual acteristics or using instrumental variables to deal with the self selection and endogeneity short migration stays in the us and frequent traveling provide

why the gender gap in wages narrowed in the 1980s since 1976 the gender gap in wages on average declined by about 1 per year this article focuses on identifying the factors underlying this trend three data sets are analyzed the current population survey the panel study of income dynamics and the national longitudinal survey we find that convergence in measurable work related characteristics schooling and work experience explains one third to one half the narrowing the remainder is attributable to a relative increase in women s returns to experience as well as to declining wages in blue collar work and other factors

incomplete market demand tests for kreps porteus selden preferences abstract what does utility maximization subject to a budget constraint imply for intertemporal choice under uncertainty assuming consumers face a two period consumption portfolio problem where asset markets are incomplete we address this question following both the standard local infinitesimal and finite data approaches to focus on the separate roles of time and risk preferences individuals maximize kps kreps porteus selden preferences the consumption portfolio problem is decomposed into a one period portfolio problem and a two period certainty consumption saving problem we derive demand restrictions which are necessary and sufficient for portfolio choices and certainty intertemporal consumption to have been generated by maximization respectively of a one period expected utility representation and a certainty representation of time preferences conditions are provided for recovering the building block time and risk preference utilities for the finite data case we derive a set of linear inequalities that are necessary and sufficient for observations to be consistent with the maximization of kps utility

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

child related transfers household labour supply and welfare what are the macroeconomic effects of transfers to households with children how do alternative policies fare in welfare terms we answer these questions in an equilibrium life cycle model with household labour supply decisions skill losses of females associated to non participation and heterogeneity in terms of fertility childcare expenditures and access to informal care calibrating our model to the u s economy we first provide a roadmap for policy evaluation by contrasting transfers that are conditional on market work childcare subsidies and childcare credits with those that are not child credits when both types can be means tested or universal we then evaluate expansions of current arrangements for the u s and find that expansions of conditional transfers have substantial positive effects on female labour supply that are largest at the bottom of the skill distribution expanding childcare credits leads to long run increases in the participation of married females of 10 6 while an equivalent expansion of child credits leads to the opposite 2 4 expanding existing programs generates substantial welfare gains for newborn households which are largest for less skilled households expanding childcare credits leads to the largest welfare gains for newborns and achieves majority support

strotz meets allais diminishing impatience and the certainty effect abstract decision makers tend to exhibit a higher degree of impatience when considering a delay to an immediate reward than when contemplating an identical delay to an equal future reward this work argues that diminishing impatience originates from the distinction between the certain present and the risky future a simple functional representation of preferences exhibiting time inconsistency when the future is uncertain is derived experimental evidence which is inconsistent with other formulations that account for diminishing impatience supports the proposed approach the new theory uncovers a tight relation between diminishing impatience and well known behavioral regularities in choice under risk and uncertainty jel d12 d81

comment on risk preferences are not time preferences separating risk and time preference andreoni and sprenger 2012a b observe that utility functions are distinct for risk and time preferences and show that their findings are consistent with a preference for certainty we revisit this question in an enriched experimental setting in which subjects make intertemporal decisions under different risk conditions the observed choice behavior supports a separation between risk attitude and intertemporal substitution rather than a preference for certainty we further show that several models including epstein and zin 1989 chew and epstein 1990 and halevy 2008 exhibit such a separation and can account for the overall experimental findings jel c91 d81 d91 risk and time preferences are the cornerstones of economic analyses regarding risk preference expected utility eu has been the predominant theory in which the curvature of the utility index captures risk attitude regarding time preference discounted utility is the most widely used model in which the curvature of the utility index captures intertemporal substitution when risk and time are intertwined integrating the two theories yields discounted expected utility deu which evaluates a contingent consumption plan c c c 3 as follows

women s earnings reexamined since a discussion of details may obscure important general issues we start by restating what we consider to be the two major contributions of our 1974 study 5 1 the methodological contribution lies in the specification of an earnings function when human capital investment occurs at different rates including zero over various segments of the life cycle such specifications are appropriate for persons when market work does not continue throughout the usual working age or for analyses of continuous work histories segmented by some relevant criteria such as job change and occupational or geographic mobility applied work on these subjects continues 1 and specifications are undergoing refinement in retrospect the model we used to analyze earnings of women is not the best but it is serviceable which permits us to refrain from injecting new matters into the present discussion 2 the substantive interest in our study of earnings of women focuses on several propositions a even with identical current characteristics women whose past experience was shorter have currently lower wages as their total job investments were smaller b total investments are smaller not only because they are spread over fewer years of work experience but also because persons who spend less time in market work invest less per year worked than persons with longer work experience c if work experience is interrupted for any significant length of time job skills tend to erode so the human capital stock is reduced by depreciation or atrophy the relevance of these propositions to the analysis of the sexual wage gap is obvious in part women s wages are lower than men s because their labor force attachment is shorter and often discontinuous also the gap widens over the life cycle since initial differences in experience are necessarily small

time preference and real investment abstract this paper studies the investment timing problem of an entrepreneur with a non tradable real option with undiversifiable risk we find that the time preference can have a significant impact on the risk attitude toward the idiosyncratic risk which results from the wealth effect on the implied option value if the agent is impatient patient an increase in idiosyncratic volatility increases decreases the agent s value and delays hastens investment this finding suggests several important implications and empirical predictions for investment decisions in private firms and public firms with concentrated ownership

human capital formation and business cycle persistence abstract in this paper we examine the role of the formation of human capital in propagating shocks over the business cycle we show that a two sector equilibrium business cycle model with human capital is able to generate persistence in the growth of output and other aggregate variables comparable to that observed in the post war us data a key feature is the relatively low elasticity of substitution between skilled and unskilled labor in the production of human capital

a theory of anticipated utility abstract a new theory of cardinal utility with an associated set of axioms is presented it is a generalization of the von neumann morgenstern expected utility theory which permits the analysis of phenomena associated with the distortion of subjective probability

underpaid and overworked measuring the effect of imperfect information on wages this paper investigates the degree of shortfall between the wages workers earn and what they could earn assuming perfect or costless information in the labor market we use the stochastic frontier regression technique to estimate the degree of shortfall found in wages on an individual basis the paper tests in addition a number of hypotheses supplied by search theory in this context the results generally confirm the propositions from search theory and indicate that on the average worker wages fall short of worker potential wages by approximately 10 percent

non global social contracts a note on inefficient social institutions this paper explores some perverse features that can emerge when social contracts are moved from a social vacuum to a setting of social interdependence in particular we note incentives that might exist in conjunction with externality problems that yield situations in which 1 social contracts reduce social wealth 2 sub global social contracts are pareto inferior to the absence of social contracts 3 there are no incentives for global social contracts while previous works emphasized the benefits of contracts this paper focuses on their costs a conclusion reached is that perhaps justice and efficiency demand not a single global social contract but rather a rich melange of sub global contracts with appropriate interstices of anarchy

time discounting for primary and monetary rewards this paper reports a positive and statistically significant relation between short term discount rates elicited with a monetary and a primary reward chocolate the relation is most evident among people who like chocolate and are hungry this finding suggests that high short term discount rates are related to an underling individual trait consistent with models of presentbiased preferences

local economic conditions and wage labor decisions of farm and rural nonfarm couples effects of geographical differences in local economic conditions on wage labor demand and wage labor participation decisions of rural couples are examined for current population survey households 1978 82 wage premiums are shown to exist for localities anticipating labor demand growth higher unemployment rates larger share of employment in services and higher costs of living these effects are stronger for males than females effects of local economic conditions on the probability of wage work are consistent with expected market wage and reservation wage effects and for farm households the probability of wage work increases when expected farm output prices decline or the wage increases

thick market effects and churning in the labor market evidence from u s cities using u s census microdata we show that on average workers change occupation and industry less in more densely populated areas the result is robust to standard demographic controls as well as to including aggregate measures of human capital and sectoral mix analysis of the displaced worker surveys shows that this effect is present in cases of involuntary separation as well on the other hand we actually find the opposite result higher rates of occupational and industrial switching for the subsample of younger workers these results provide evidence in favor of increasing returns to scale matching in labor markets results from a back of the envelope calibration suggest that this mechanism has an important role in raising both wages and returns to experience in denser areas

risk aversion in the theory of expected utility with rank dependent probabilities expected utility with rank dependent probability theory is a model of decision making under risk where the preference relations on the set of probability distributions is represented by the mathematical expectation of a utility function with respect to a transformation of the probability distributions on the set of outcomes this paper defines based on g teaux differentiability measures of risk aversion for such preferences which characterize the relation more risk averse and applies these measures to the analysis of unconditional and conditional portfolio choice problems

urban effects on participation and wages are there gender differences abstract this paper estimates participation and wage equations using panel data from the united kingdom to explore gender differences in urban wage and participation premiums the results suggest a small but economically significant urban participation premium for women but none for men results from the wage estimations suggest that after controlling for sample selectivity observed and unobserved heterogeneity the urban premium is larger for women this wage premium is also larger for married or cohabiting women relative to others there is also evidence of higher urban returns to experience for men and lower urban wage depreciation for both men and women

the rate of return to investments in on the job training in this paper we use the overtaking method to calculate marginal rates of return to on the job training as we have no prior information on who invests in ojt and who does not we use a switching regression model with unknown regimes to obtain parameter estimates of the wage profiles the estimation results show that lower intercepts are associated with steeper wage profiles this confirms the prediction that those who invest in ojt have lower initial wages but higher wage growth we further find that the marginal rate of return to ojt is high and increases with education

risk preferences are not time preferences reply can the well known experimental phenomenon of present bias in intertemporal choice be confounded with the risks associated with receiving payment can measurements of risk preferences be used to represent desires for smoothness in intertemporal payments in our two 2012 papers in this journal we explored these two questions and found the answer to the first to be yes and the second to be no we feel the three papers inspired by our work and published here underscore these arguments and point to interesting new possibilities for modeling and measuring risk over time jel c91 d81 d91

foreign capital and gender differences in promotions evidence from large brazilian manufacturing firms proquest denotes formulae omitted widespread consensus asserts that occupational segmentation is the chief determinant for gender differences in wages in the brazilian labor market see for example oliveira 2001 although women represent 39 percent of the formal workforce in brazil they amount to only 23 percent of the employees in the sectors that pay relatively higher wages in 2004 as well the predominance of segmentation increases if one restricts attention to managerial positions of which women hold only 14 percent this suggests that limited promotion prospects for women in the brazilian job market may present barriers to their promotion to the upper rungs of the corporate ladder this paper contributes to the literature by examining data from the larg est firms of the brazilian manufacturing industry in particular our goal is to determine whether obstacles to women s ascension exist by tracking the amount of time it takes for a woman to get a promotion to a managerial posi tion the aim is to complement the literature on gender differences in promo tions whose papers mainly focus on computing the promotion rates time to promotion offers a different angle in that samples with a large time span could well present similar likelihoods of promotion for both genders even if the promotion durations are different we construct the duration variable by following from january 1996 to december 2005 every individual who enters the annual report of social information rais database between january 1991 and december 1995 we denote as nonpromoted the individuals who do not obtain a promotion to a managerial position within the sample that is the right censored observations whereas we assign duration zero to the workers who already are in managerial positions in january 1996 accordingly we label as promoted the individuals within our sample who rise to a managerial position that is those with uncensored positive durations investigating dif ferences in promotions is particularly difficult because observationally simi lar male and female workers may display equal promotion rates and durations even in the presence of gender differences for example promotions may differ in quality as far as we know this is the first study to examine gender differences in promotions using microdata from a developing country apart from the obvious interest in finding whether the main stylized facts hold in a latin american country we were also motivated by the quality and availability of the brazilian data in contrast to the many studies that employ data from individual firms see for example cabral ferber and green 1981 gerhart and milkovich 1989 baker gibbs and holmstrom 1994 our study relies on a homogeneous sample of recently hired workers from the brazilian manufac turing industry in the period from 1996 to 2005 our data set is particularly convenient first the data include a wide array of controls for worker and firm characteristics second unlike blau and devaro 2007 we observe multiple workers per establishment at different occupations and hierarchical levels as well as their career paths in terms of occupation and wage a potential limi tation is that our data set does not include any direct measure of on the job productivity and hence we must come up with indirect controls interestingly we find that there are significantly fewer gender differences in the time to promotion within foreign owned firms than within domestic firms in the brazilian manufacturing industry our findings complement to some extent the literature on the differences between multinationals and domestic firms doms and jensen 2006 greene and others 2009 as well as the evidence that gender differences may depend on the nature of the firm 1 we argue that such gender differences are consistent with statistical discrimi nation and self selection we reason as follows suppose there are relatively more women than men who prefer to dedicate more time to their family than to their careers

nonemployment stigma as rational herding a field experiment abstract long spells of unemployment are known to reduce the likelihood of re employment but it is difficult to discern the reasons for this observation using an experimental method that controls for search intensity and possible discouragement of job applicants i document that job market opportunities for the nonemployed diminish rapidly over time in this experiment duration dependence is solely due to firm perceptions why do firms view long spells of nonemployment as negative signals rational herding is one important factor managers believe that unemployed applicants were previously interviewed and if the applicants were productive they would have been hired

the consequences of long term unemployment evidence from linked survey and administrative data that the long term unemployed fare worse in the labor market than do the short term unemployed is well known but why one potential explanation is that the long term unemployed are bad apples wh

intertemporal tradeoffs for gains and losses an experimental measurement of discounted utility this article provides a parameter free measurement of utility in intertemporal choice and presents new and more robust evidence on the discounting of money outcomes intertemporal utility was concave for gains and convex for losses consistent with a hypothesis put forward by loewenstein and prelec 1992 discount rates declined over time but less so than previously observed under the assumption of linear utility for approximately 40 of our subjects constant discounting provided the best fit the remaining 60 were most consistent with harvey s 1986 power discounting our data provide little support for the popular quasi hyperbolic model which is widely used in economics today we observed an asymmetry in the discounting of gains and losses that unlike earlier findings cannot be explained by a framing effect

estimating time preferences from convex budgets experimentally elicited discount rates are frequently higher than what seems reasonable for economic decision making such high rates are often attributed to present biased discounting a well known bias of standard measurements is the assumption of linear consumption utility attempting to correct this bias using measures of risk aversion to identify concavity researchers find reasonable discounting but at the cost of exceptionally high utility function curvature we present a new methodology for identifying time preferences both discounting and curvature from simple allocation decisions we find reasonable levels of both discounting and curvature and surprisingly dynamically consistent time preferences jel c91 d12 d81 understanding and estimating time preferences is obviously of great importance to economists marketers and policy makers consumers decide how much to invest in savings education real estate and life insurance how much to diet exercise and smoke whether to marry when to have children and what to leave in their wills while there has been substantial research estimating time preferences using aggregate consumption data 1 the bulk of the effort has occurred in laboratory environments 2 among the many laboratory techniques employed recent studies have favored multiple price lists mpl with monetary payments 3 with mpls individuals are asked multiple times to choose between smaller payment amounts closer to the present and larger amounts further into the future the interest rate increases monotonically in a price list such that the point where an individual switches from preferring sooner payments to later payments carries interval

violence and risk preference experimental evidence from afghanistan comment in this comment on callen et al 2014 i revisit recent evidence uncovering a preference for certainty in violation of dominant normative and descriptive theories of decision making under risk i show that the empirical findings are potentially confounded by systematic noise i then develop choice lists that allow me to disentangle these different explanations experimental results obtained with these lists reject explanations based on a preference for certainty in favor of explanations based on random choice from a theoretical point of view the levels of risk aversion detected in the choice list involving certainty can be accounted for by prospect theory through reference dependence activated by salient outcomes

time consistency stationarity and time invariance a sequence of experiments documents static and dynamic preference reversals between sooner smaller and later larger rewards when the sooner reward could be immediate the theoretically motivated design permits separate identification of time consistent stationary a ndtime invariant choices at least half of the subjects are time consistent but only three quarters of them exhibit stationary choices about half of subjects with time inconsistent choices have stationary preferences these results chal lenge the view that present bias preferences are the main source of time inconsistent choices the past twenty years have seen a surge of interest in time inconsistent preferences mostly this has been motivated by psychological experiments and introspection that have suggested the existence of present bias a decision maker prefers smaller immediate reward to a larger delayed reward but when she is asked about her preferences between these two alternatives when both are equally shifted into the future her preferences are reversed although there is no inconsistency per se in her answers this behavior has been taken to suggest that when the decision maker will be asked to update her choices in the future she will generally deviate from her ex ante plans our goal in the present study is to perform a dynamic preference reversal experiment as such one is required to extend the standard framework of pref erences over temporal payments to a dated collection of such preferences this extension allows us to formally define three distinct properties stationarity im plies that ranking of temporal payments depends only on the time distance and payment distance between the alternatives time invariance assumes that the decision maker evaluates each temporal payment relative to the evaluation pe

returns to human capital under the communist wage grid and during the transition to a market economy we estimate returns to human capital during communism and the transition using data on 2 284 men in the czech republic we show a extremely low and constant rates of return to education under the communist wage grid and dramatic increases in transition which do not differ by firm ownership b radical changes in returns to several fields of study and sheepskin effects in both regimes c identical wage experience profile in both regimes d similar 1996 returns to human capital obtained in communism and in transition and e changes in the interindustry wage structure a decomposition of the variance of wages finds individuals unobservable effects from communism to persist into transition but most of the variance is due to unobservable effects introduced in the transition

risk preferences are not time preferences risk and time are intertwined the present is known while the future is inherently risky this is problematic when studying time prefer ences since uncontrolled risk can generate apparently present biased behavior we systematically manipulate risk in an intertemporal choice experiment discounted expected utility performs well with risk but when certainty is added common ratio predictions fail sharply the data cannot be explained by prospect theory hyperbolic discounting or preferences for resolution of uncertainty but seem consistent with a direct preference for certainty the data suggest strongly a difference between risk and time preferences jel c91 d81 d91 understanding individual decision making under risk and over time are two foundations of economic analysis 1 in both areas there has been research to suggest that standard models of expected utility eu and exponential discounting are flawed or incomplete regarding time experimental research has uncovered evidence of a present bias or hyperbolic discounting frederick loewenstein and o donoghue 2002 regarding risk there are number of well documented departures from eu such as the allais 1953 common consequence and common ratio paradoxes an organizing principle behind expected utility violations is that they seem to arise as so called boundary effects where certainty and uncertainty are combined camerer 1992 harless and camerer 1994 and starmer 2000 indicate that violations of expected utility are notably less prevalent when all choices are uncertain this observation is especially interesting when considering decisions about risk taking over time in particular certainty and uncertainty are combined in intertemporal decisions the present is known and certain while the future is inherently risky this observation is problematic if one intends to study time preference in isolation from

home production with endogenous growth abstract benhabib et al 1991 and greenwood and hercowitz 1991 demonstrate that general equilibrium beckerian home production models that incorporate separate technology shocks to the home and market production functions are able to explain either the comovements in employment across consumption and investment sectors of the economy or the comovement in output across market and home investment sectors but not both simultaneously this paper demonstrates that these comovements can be resolved by introducing endogenous growth into the model while retaining only a single technology shock to market production the additional margin for allocating time between formal training and market activities is sufficient to bring about the observed positive comovements in employment and output across sectors

work power and earnings of women and men numerous studies have established that part of the very substantial male female earnings gap is explained by differences in the amount of human capital workers have accumulated see for example jacob mincer and haim ofek 1983 institutional factors have also been found to play a role in determining wages david gordon et al 1982 occupation further helped to explain the remaining gap but several researchers have shown that introducing dimensions of work authority by taking into account the individual s position in the work hierarchy explains more of the variation in earnings than does occupation martha hill 1980 last two recent studies ferber and spaeth 1984 spaeth 1985 also included control over monetary resources this variable added substantially to the explanatory power of earnings regressions even after human capital variables institutional factors and several other measures of work authority had been entered like the other studies ferber and spaeth also found that reward structures for men and women are quite different suggesting the possible existence of discrimination the question whether women may also be at a disadvantage in achieving control over monetary resources was not investigated when hill examined the process of achievement of work authority she found substantial differences between male and female workers in this paper we examine whether the same is true for attaining financial control i data and analysis
