the dog that did not bark the eitc for single mothers in the netherlands abstract we study the extension of an eitc for single mothers in the netherlands to mothers with a youngest child 12 to 15 years of age this reform increased the net income gain of moving into employment for the treatment group by 31 using both dd and rd we show that this reform had a negligible effect on labour participation with tight confidence intervals around zero our results are at odds with a number of related studies this finding may be due to our treatment group of single mothers of which the youngest child is relatively old or because the reform we consider was less salient furthermore related studies typically study changes in a tax credit which was part of a broader reform package making it harder to isolate the effect of the tax credit also we show that using single women without children as the control group as is commonly done in related studies can be problematic

grain transport and rural credit in mozambique solving the space time problem this paper shows how credit market failures can lead to large welfare losses in grain markets by inducing increased transport for seasonal storage in locations with low credit costs the burden of these welfare losses falls primarily on rural households these conclusions are obtained from a spatial temporal model solved using a mixed complementarity formulation that easily handles interest rate differentials across space efforts to address credit market failures and to improve the efficiency of rural storage should be given priority as opposed to the creation of large formal sector grain collection centers

child care policy and the labor supply of mothers with young children a natural experiment from canada in 1997 the provincial government of quebec the second most populous province in canada initiated a new child care policy licensed child care service providers began offering day care spaces at the reduced fee of 5 00 per day per child for children aged 4 by 2000 the policy applied to all children not in kindergarten using annual data 1993 2002 drawn from statistics canada s survey of labour and income dynamics the results show that the policy had a large and statistically significant impact on the labor supply of mothers with preschool children

marriage cohabitation and women s response to changes in the male wage structure using microdata and grouped data that cover the period 1996 to 2006 we assess the extent to which cohabiting women adjust their labour supply to a lesser extent if any than married women in response to changes in male wages both microdata regressions and grouping estimators unambiguously indicate that cohabiting women respond less to variation in male wages than married women however the magnitude of the difference is not sizeable we also assess the magnitude of married men s and cohabiting men s own wage elasticities and find that they do not differ much combined with the fact that male earnings account for roughly two thirds of family earnings these two findings explain why the impact of changes in male wages on family earnings is very similar for married couples and cohabiting couples in both cases a 10 decline in male wages appears to induce roughly a 6 drop in family earnings

spatial price discrimination in agricultural product procurement markets a computational economics approach significant transport costs and spatially distributed supply and processing create oligopsony power in agricultural markets price discrimination expressed in the form of partial or complete absorption of freight charges by processors is often observed in these environments but we understand little about how these pricing decisions are made analytical approaches are often intractable as an alternative we propose a computational economics approach to analyze a general spatial competition model and study firms choices of spatial pricing policy instead of the commonly presumed free on board pricing we find that buyers choose price discrimination either through uniform delivered pricing or through partial freight absorption

international competition income distribution and economic growth this paper shows that the neo keynesian case for wage led growth does not generally hold in an open economy model wage increases cause a loss of competitiveness that reduces the trade balance if the economy is relatively open to trade and price elasticities satisfy certain restrictions the worsening of the trade balance more than outweighs the increase in workers consumption thus reducing the growth rate the main theoretical innovation is a flexible markup pricing rule that allows changes in unit labor costs and exchange rates to affect profit margins implications for international relations and class conflict are discussed copyright 1989 by oxford university press

the market work behavior and wages of women 1975 94 changes in the labor market participation and wages of women in the united states are analyzed over the period 1975 1994 using data from the current population survey women are organized into nine birth cohorts five schooling groups and each year of age from 25 to 60 years and their weekly and annual work hours their annual work weeks their employment population ratio and their real average hourly earnings tabulated schooling differences in work behavior have become wider in recent cohorts as have their wages the relationship between work and wages is estimated for women of different ages cohorts and marital status the gap between the work of unmarried and married women has narrowed and the role of wages both the wages of women and those of husbands is examined to determine the extent to which changes in wages account for these movements excerpt

joint labor supply and childcare choice decisions of married mothers this paper examines the impact of childcare prices and wage rates on the joint employment and childcare mode center sitter relative and husband choice decisions of married mothers by estimating both a mixed logit and universal logit choice model data are drawn from the 1988 canadian national child care survey and the 1988 labour market activity survey the estimation results show that wages have a positive impact on the probability of choosing any of the working states and that childcare prices for center sitter and relative care reduce the probability of working and using each respective mode of care sensitivity analyses reveal that the wage elasticity for employment is fairly robust across model specifications while the own price elasticity of childcare is sensitive to model specification differing identifying assumptions in the estimation of childcare price equations and sample selection the simulation results show that differences exist in the degree to which government subsidies in the form of wage subsidies targeted childcare subsidies or unconditional childcare subsidies impact on labor supply decisions and decisions to substitute across different modes of care by those mothers already in the labor market

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

why is the labour force participation of women declining in india summary this paper explores the recent fall in female labour force participation and its socio economic determinants in india the major contribution of this paper is to explore both micro and macro level factors which determine female labour force participation rate lfpr to examine the u shape female lfpr by examining the likely income and substitution effects of the real wage increase to identify the sub sectors within manufacturing and service sectors that could create jobs for new female job aspirants and those older women displaced from agriculture in recent years and thus to understand the conditions under which female lfpr could be raised using both macro level and household survey nss data we find that the recent fillip in the process of structural transformation has pushed a large number of females out of agriculture the growing mechanization in agriculture and rising capital intensity in manufacturing sectors together have limited the opportunity for females because of their low education and skill and due to other cultural constraints we also found that the rise in real wages in rural areas and the consequent improvement in the standard of living has produced a strong negative income effect which outweighs the positive substitution effect and as a result female lfpr has declined substantially however with the massive increase in female enrollment in secondary and higher levels of education it could be expected that the substitution effect of the increase in real wage would become stronger if appropriate measures are taken by the government which are suggested

does the labour supply of wives respond to husbands wages canadian evidence from micro data and grouped data using micro data and grouped data we assess the extent to which canadian wives adjusted their labour supply in response to changes in husbands wages during the period 1980 2000 grouped data parameters based on weighted least squares and the unbiased error in variables estimator developed by devereux 2004 2007a b yield cross wage elasticities that are substantially higher in absolute value than those derived from ols regressions run on micro data both grouping estimators indicate that the labour supply of canadian wives responded strongly to changes in husbands wages during the 1980s for the 1990s our estimates of wives cross wage elasticity display greater dispersion a l aide de micro donnees et de donnees groupees on etablit jusqu a quel point les epouses canadiennes ont ajuste leur offre de travail en reponse aux changements dans les salaires de leurs epoux au cours de la periode 1980 2000 les parametres pour les donnees groupees derives par la methode des moindres carres ponderes et de l estimateur developpe par devereux 2004 2007a b engendrent des elasticites croisees qui sont substantiellement plus grandes en termes absolus que ceux derives par la methode des moindres carres ordinaires en utilisant des micro donnees les deux estimations montrent que l offre de travail des epouses canadiennes a repondu fortement aux changements dans les salaires des epoux au cours des annees 80 pour les annees 90 les evaluations des elasticites croisees des salaires montrent une plus grande dispersion

what explains the stagnation of female labor force participation in urban india female labor force participation rates in urban india between 1987 and 2011 are surprisingly low and have stagnated since the late 1980s despite rising growth fertility decline and rising wages and education levels married women s labor force participation hovered around 18 percent analysis of five large cross sectional micro surveys shows that a combination of supply and demand effects have contributed to this stagnation the main supply side factors are rising household incomes and husband s education as well as the falling selectivity of highly educated women on the demand side the sectors that draw in female workers have expanded least so that changes in the sectoral structure of employment alone would have actually led to declining participation rates

comparing labor supply elasticities in europe and the united states new results we suggest the first large scale international comparison of labor supply elasticities for 17 european countries and the united states using a harmonized empirical approach we find that own wage elasticities are relatively small and more uniform across countries than previously considered nonetheless such differences do exist and are found not to arise from different tax benefit systems wage hour levels or demographic compositions across countries suggesting genuine differences in work preferences across countries furthermore three other findings are consistent across countries the extensive margin dominates the intensive margin for singles this leads to larger responses in low income groups and income elasticities are extremely small

a comparison of the labor force behavior of married women in the united states and canada with special attention to the impact of income taxes estimation results are presented for the probability of working the hourly wage rate and the annual hours of work for wives in seven different age groups in both the u s and canada federal and state or provincial taxes are incorporated into the analysis an iterative estimation method is employed to circumvent the statistical problems resulting from the dependence of the hours of work on the tax rate and the dependence of the tax rate on the hours of work authors

the effects of joint taxation of married couples on labor supply and non wage income abstract the united states changed its tax treatment of married couples in 1948 from a system in which each spouse paid taxes on his or her own income to a system in which a married couple is taxed as a unit the switch from separate to joint taxation changed incentives for labor supply and asset ownership this paper investigates the effects of the conversion to joint taxation taking advantage of a natural experiment created by cross state variation in property laws married individuals in states with community property laws had always been taxed as if each spouse had earned half of the couple s income and thus were unaffected by the 1948 legal change comparing the behavior of highly educated taxpayers in affected and unaffected states indicates that the tax change is associated with a decline of approximately 2 percentage points in the employment rate of married women consistent with the higher first dollar tax rates they faced after 1948 women married to self employed men were also less likely to have non wage income after 1948 reflecting pre 1948 allocation of family assets to wives for tax purposes the effects of joint taxation on married men s labor force participation and non wage income holding are generally not statistically significant

canadian contributions to family economics canadian scholars have made substantial contributions to the relatively new field of family economics these include new models of how men and women match in marriage markets and of how decisions are made in multi person households several were early contributors to the literature on married women s labour supply and labour supply in a family context and helped to develop empirical methods in this area a particular focus has been on the impacts of policy relevant parameters such childcare costs on family labour supply and child well being new work on child development the impact of early life conditions and the processes of intergenerational transmission also highlight the importance of family context in determining economic well being

national family policies and mothers employment how earnings inequality shapes policy effects across and within countries although researchers generally agree that national family policies play a role in shaping mothers employment there is considerable debate about whether how and why policy effects vary across co

changes in relative wages and family labor supply the large changes in relative wages that occurred during the 1980s provide fertile ground for studying the behavioral responses of married couples to the wage changes of husbands and wives i find estimates of own wage and cross wage elasticities for men that are very small the own wage elasticity for women is positive and the cross wage elasticity for women suggests a strong negative response of female labor supply to changes in their husband s wages family labor supply behavior determines how changes in individual wage rates translate into family earnings changes the responses of women to changes in their husband s wages attenuated somewhat the increases in individual wage inequality at the family level the results suggest that the earnings of the wives of low income men would actually have fallen over the decade if women s labor supply did not respond to changes in their husbands wages however assortative mating implies that wage changes of husbands and wives are correlated and so family earnings inequality still grew during the decade of the 1980s

employment and child care choices in canada and the united states in this paper we examine employment and child care choices of two parent families with young children in the united states and canada using a pooled data set based on recent national surveys in each country we find that the employment and child care choices of canadian families are similar to those of u s families estimates of a model of employment and child care choices indicate significant effects of child care subsidies child care prices and wage rates on employment and child care choices however none of these factors helps to explain the differences in employment and child care choices between the two countries ce memoire examine le choix de l emploi et du soin des enfants dans les familles ou il y deux parents aux etats unis et au canada en utilisant des donnees d etudes recentes dans les deux pays il appert que les choix des familles canadiennes sont semblables a ceux des familles americaines les calibrations d un modele de ces choix montrent les effets significatifs des subventions au soin des enfants du prix des soins des enfants et des taux de salaires sur ces choix cependant aucun de ces facteurs n explique les diffrences dans les patterns de choix entre les deux pays

revising our thinking about the relationship between maternal labor supply and preschool many argue that childcare costs limit the labor supply of mothers though existing evidence has been mixed using a child s eligibility for public kindergarten in a regression discontinuity instrumental variables framework i estimate how use of a particular subsidy public school affects maternal labor supply i find public school enrollment increases only the employment of single mothers without additional young children i compare this result to previous work focusing on striking increases in a similar setting but earlier period gelabch 2002 differences in the population of mothers labor supply and patterns of lifecycle events likely drive the discrepancy in results

rational household labor supply traditionally household behavior is derived from the maximization of a unique utility function in this paper we propose an alternative approach in which the household is modeled as a two member collectivity taking pareto efficient decisions the consequences of this assumption are analyzed in a three good model in which only total consumption and each member s labor supply are observable if the agents are assumed egoistic i e they are only concerned with their own leisure and consumption it is possible to derive falsifiable conditions upon household labor supplies from both a parametric and nonparametric viewpoint if alternatively agents are altruistic restrictions obtain in the nonparametric context useful interpretation stems from the comparison with the characterization of aggregate demand for a private good economy

labor supply at the extensive and intensive margins the eitc welfare and hours worked some previous studies have emphasized differences between labor supply responses on the extensive margin participation and intensive margin hours worked e g james j heckman 1993 jean kimmel and thomas j kniesner 1998 recent tax and welfare policy changes provide a potentially more convincing way of identifying these responses than is available in other nonexperimental data the earned income tax credit eitc changes during the 1990 1996 period sharply altered the budget sets of single mothers over a short period of time these changes in incentives are likely to be unrelated to differences across individuals in the desire to work and thus are likely to be exogenous to labor supply decisions this lack of exogeneity is harder to claim for wage differences across people which are the main alternative source of identifying variation in addition to preference heterogeneity wages are driven by supply and demand factors that one must account for to obtain valid estimates using wage variation the eitc unequivocally encourages single parents to work at least some hours during a year because it shifts out the budget set at all positive hours points this first prediction is clearly confirmed by the data in addition theory implies that the eitc will decrease hours worked among those already working because most recipients are on the plateau or phase out portions of the credit schedule for these recipients the eitc reduces or does not affect the after tax wage while at the same time discouraging work through the income effect of the credit payment however recent hours worked patterns for eitc eligible individuals do not appear to fit this second prediction hours and weeks worked by likely recipient groups have not fallen this paper analyzes this puzzling finding building on earlier work by nada eissa and jeffrey liebman 1996 and meyer and dan t rosenbaum 1999 this study shows that nearly all of the laborsupply adjustment of single mothers occurs at the extensive margin not the intensive margin this finding raises the issue of what model features are needed to explain both participation and hours but leaves the answer to be provided in future work this finding also suggests that the large literature simulating alternative policies for low wage workers such as the eitc may be misleading because nearly all work has used models that imply similar responses on participation and hours margins

labour supply of married women in canada 1980 this study uses recently released data from the 1981 census to reex amine the labor supply behavior of married women in canada using j j heckman s procedure to correct for selectivity bias and incorporating the influence of income taxes this study finds small wage and income effects on canadian wives labor supply the estimat es are similar in magnitude to those reported by a n akamura and m nakamura 1981 in their study of data from the 1971 census and t o t he estimates reported in a more recent canadian study by c robinson and n tomes 1985 who used data drawn from the 1979 quality of life survey

the evolution of high incomes in northern america lessons from canadian evidence this paper uses tax statistics to construct new series on canadian top income shares from 1920 to 2000 and provides a systematic comparison with the u s experience as in the united states top income shares in canada display a ushaped pattern over the century with a precipitous drop during world war ii followed by a slower decline until 1970 since the late 1970s top income shares have been increasing dramatically and the very top shares are now as high as in the pre war era as in the united states the recent increase in top income shares is the consequence of a surge in top wages and salaries the canadian experience since the late 1970s does not appear to be well explained by tax changes suggesting that the upward trend in canada derives from the united states perhaps because many high income canadians have an emigration option this in turn suggests that the recent increase in u s personal income top shares is not merely a change in tax reporting behavior the recent sharp increase in top income shares in canada is of the same magnitude at the individual and family level and is not due to an increase in income mobility

changes in labor force participation in the united states the labor force participation rate in the united states increased almost continuously for two and a half decades after the mid 1960s pausing only briefly during economic downturns the pace of growth slowed considerably during the 1990s however and after reaching a record high of 67 3 percent in the first quarter of 2000 participation had declined by 1 5 percentage points by 2005 this paper reviews the social and demographic trends that contributed to the movements in the labor force participation rate in the second half of the twentieth century it also examines the manner in which developments in the 2000s reflect a break from past trends and considers implications for the future

whose preferences are revealed in hours of work it has become orthodox in economics research to interpret the association between hourly earnings and working hours as the expression of the preferences of workers this convention originated in h gregg lewis explanation for the decline in hours of work since the nineteenth century his explanation rested on an explicit resolution of the identification problem inherent in any quantity hours price wage relation for over 40 years researchers have neglected this identification problem with the result that the findings in the purported labor supply literature are of questionable value jel j22 j23 c13

the aggregate implications of changes in the labour force composition abstract labour composition by gender age and education has undergone dramatic changes over the last half century in the united states furthermore the volatility of total market hours differs systematically between genders age and education groups i develop a large scale business cycle model where these demographic patterns and their transitional dynamics are taken into account and find that demographic change accounts for 30 of the observed changes in aggregate volatility over this period of time additionally these demographic changes are responsible for a significant fraction of the gdp growth observed in the considered period of time

labor force participation and monetary policy in the wake of the great recession in this paper we provide compelling evidence that cyclical factors account for the bulk of the post 2007 decline in the u s labor force participation rate we then proceed to formulate a stylized new keynesian model in which labor force participation is essentially acyclical during normal times that is in response to small or transitory shocks but drops markedly in the wake of a large and persistent aggregate demand shock finally we show that these considerations can have potentially crucial implications for the design of monetary policy especially under circumstances in which adjustments to the short term interest rate are constrained by the zero lower bound

the state and industrial strategy abstract the debate about the role of the state in promoting industrial growth in developing economies is reviewed we begin with the ideas of the early development economists of the 1950s and 1960s then take up two waves of neoclassical criticism respectively emphasizing the primacy of the market and the lack of autonomy and competence of the developmentalist state and sketch the elements of a countercritique the fact that all successfully developing economies apply industrial strategies incorporating institutional change is emphasized and boundary conditions and lessons from experience which delimit sensible strategic choices are pointed out

the wage elasticity of informal care supply evidence from the health and retirement study author affiliation olena nizalova nizalova kse org ua acknowledgment i gratefully acknowledge steven haider jeff biddle john strauss and john goddeeris for their helpful comments throughout the process of working on the project and important comments from the anonymous referees i am also greatly indebted to michael nolte and his colleagues from the isr data enclave for making possible the revision of this article 1 introductionfor the past two decades the policy debate on issues related to the aging population has been growing at unprecedented rates throughout the world on one hand policy measures suggested in the debate include removal of the disincentives for labor force participation for the near elderly u s dhhs 1997 apfel 2004 cbo 2004 this would have effectively raised the wage rate faced by the targeted group as in the case of the elimination of the social security earnings test for those older than 65 in the united states friedberg 2000 on the other hand the role of informal caregiving is emphasized as a means to keep many individuals at home who would otherwise require expensive institutional care u s dhhs 1997 p 6 policies targeting these two objectives may turn out to conflict with each other higher wages may decrease hours devoted to informal care for elderly parents while policies encouraging informal care may lead to fewer working hours research on the effects of the social security earnings test mostly focuses on labor supply and claiming behavior of the affected group burtless and moffitt 1984 baker and benjamin 1999 gruber and orszag 1999 friedberg 2000 haider and loughran 2008 with little attention being paid to the potential interaction between incentives for paid employment and caregiving choices this interaction may have adverse implications for the well being of the oldest old given that the prevalence of caregiving is highest among individuals in their late midlife central to the analysis of this interaction is the concept of the wage elasticity the labor supply literature suggests a positive wage elasticity of labor supply smaller for males larger for females therefore if the wage elasticity of informal care supply is close to zero as has been found in earlier studies higher wages would lead to more labor supplied with negligible effects on the provision of informal care in this case one might hope that benefits from increased labor supply will not be offset along other dimensions if on the contrary the wage elasticity of informal care supply is relatively large and negative one should be more cautious when evaluating the effects of fiscal policies on labor supply among individuals in their late midlife a substantial negative wage elasticity of informal care supply would mean that along with increasing labor supply the near elderly would cut back on the hours of informal care they provide to their elderly parents this may potentially lead to more people turning to the government in their quest for help with covering formal long term care costs the goal of this article is to study the wage elasticity of informal care supply and contribute to the literature by directly addressing the issue of omitted variables in the time allocation and monetary transfer equations informal care supply is defined as annual time spent helping elderly parents with basic personal needs as well as household chores errands and transportation this article uses a unique opportunity of access to the restricted geographic identifiers for the health and retirement study hrs respondents to instrument hourly wages with the industry structure in the state of residence allowing for differential impact by education 1the primary finding of the article suggests that the wage elasticity of informal care supply is negative and substantially larger in magnitude than previously estimated due to the weakness of the instruments there is still a significant remaining bias in the estimates of the wage elasticity

modeling spatial price transmission in the grain markets of ethiopia with an application of ardl approach to white teff following the agricultural market liberalization policy there is an emerging grain market structure in ethiopia in which the central wholesale market exhibits concentration of power and spatial integration with the local markets due to this it is hypothesized that the central wholesale market influences the long run price movements in the local markets the relationship can be modeled as spatial price equilibrium with the aim to guide subsequent policy decisions with regard to public intervention in the post liberalization period in this study we modeled the spatial equilibrium relationship between the producer and the wholesale prices of white teff a major staple in ethiopia using the autoregressive distributed lag modeling approach to cointegration analysis first the existence of a nonspurious long run relationship in levels between the producer prices in the local market and the wholesale prices in the central market is confirmed second the long run relationship and the error correction model for the producer price are estimated the results reveal that the wholesale price of white teff in the central consumer market is a major short and long run determinant of the producer price in the local supply markets therefore the institutional role of the government with the aim of improving producers marketing margin and the overall performance of the grain markets in the post liberalization period can be influenced through targeted interventions at the central wholesale market

wage inequality and family labor supply using the march current population surveys and the 1960 census this article describes earnings and employment changes for married couples in different types of households stratified by the husband s hourly wage while declines in male employment and earnings have been greatest for low wage men employment and earnings gains have been largest for wives of middle and high wage men these findings cast doubt on the notion that married women have increased their labor supply in the recent decades to compensate for the disappointing earnings growth of their husbands

collective decisions household production and labor force participation in this paper we generalize the collective model of household labor supply with domestic production to allow for the possibility of nonparticipation in the labor market we also relax the marketability assumption according to which domestic goods and market goods are perfectly substitutable our results are twofold first we show that the main structural components of the decision process can be retrieved from observed behavior second we estimate a system of market and domestic labor supply using the panel study of income dynamics and apply the theoretical results to recover the intra household sharing of resources

single women s labor supply elasticities trends and policy implications this paper uses cps data to examine changes in single women s labor supply elas ticities in recent decades specifically the authors investigate trends in how single women s hours of work and labor force participation rates responded to both wages and income over the years 1979 2003 results from the base specification suggest that over the observation period hours wage elasticities decreased by 82 participation wage elasticities by 36 and participation income elasticities by 57 these results imply that changes in tax policy had a much larger effect on the labor supply and labor force participation behavior of women in this subpopulation in the early 1980s than in recent years i t is well documented that over the past few decades female labor force behavior has undergone substantial changes women s labor force participation rates have increased markedly as have their annual hours of work at the same time the marital composition of women has undergone a substantial change as well with the proportion of married women falling steadily over time as a result single women comprise a greater share of the labor force than in earlier years and hence their behavioral responses to changes in wages and incomes carry even greater importance for the effects of changes in tax and transfer policies despite the large increase in the number of single women over the past decades single women s labor supply behavior has received

more on the labour supply of canadian women the traditional consensus on female labour supply is that the wage elasticity is large and positive in contrast to a small and generally negative elasticity for males this consensus has recently been challenged in a series of important papers by alice and masao nakamura who find a backward bending supply curve for females similar to that for males this result has been challenged on a variety of grounds the present paper tests the hypothesis advanced by the nakamuras on data that have several advantages over the census type in their papers the results offer strong support for the nakamuras conclusions

swimming upstream trends in the gender wage differential in the 1980s using michigan panel study of income dynamics data for 1979 and 1988 we analyze how a falling gender wage gap occurred despite changes in wage structure unfavorable to low wage workers the decrease is traced to gender specific factors which more than counterbalanced changes in measured and unmeasured prices working against women supply shifts net of demand were unfavorable for women generally and hurt high skilled more than middle and low skilled women by analyzing wages we find support for the notion of a gender twist in supply and demand having its largest negative effect on high skilled women

the effect of universal child benefits on labour supply using a difference in differences estimator i find the canadian universal child care benefit has significant negative income effects on the labour supply of married individuals the likelihood of lower educated mothers to participate in the labour force is reduced 3 2 percentage points when receiving the benefit median hours worked per week among lower educated mothers is reduced by 1 9 hours the effects on higher educated mothers are substantial with median hours worked among higher educated mothers reduced by nearly one hour per week for men the evidence suggests small but significant income effects on labour supply consistent with the literature on labour supply elasticities

labor supply of husbands and wives a simultaneous equations approach labor supply functions for married men and women are formulated as a dynamic simultaneous equations system which is estimated using panel data controlling for fixed individual effects allows marginal labor supply responses to be disentangled from permanent patterns in hours worked due to assortative mating the results suggest that the labor supply of husbands and wives without pre school children is not jointly determined in the short run while families with young children exhibit strong interactions in work hours and negative cross earnings effects neither the joint utility model of family labor supply nor an ad hoc traditional family model is supported by these results the data are for the united states and concern 381 couples from the denver income maintenance experiment excerpt

labor supply elasticities overcoming nonclassical measurement error using more accurate hours data we measure the impact of measurement error in labor supply elasticities estimated over recalled usual work hours as is ubiquitous in the literature we employ data on hours of work in diaries collected by the american time use survey 2003 2015 along with the same respondents recalled usual work hours estimates using the latter yield elasticities that are positively biased we argue that this bias arises from the salient effects of differences in wage rates on recalled hours abstract from author

positive and normative judgments implicit in u s tax policy and the costs of unequal growth and recessions calculating the welfare implications of changes to economic policy or shocks requires economists to decide on a normative criterion one approach is to elicit the relevant moral criteria from real world policy choices converting a normative decision into a positive inference as in the recent surge of inverse optimum research we find that capitalizing on the potential of this approach is not as straightforward as we might hope we perform the inverse optimum inference on u s tax policy from 1979 through 2010 and argue that the results either undermine the normative relevance of the approach or challenge conventional assumptions upon which economists routinely rely when performing welfare evaluations

rising u s earnings inequality and family labor supply the covariance structure of intrafamily earnings this paper studies the labor supply contributions to individual and family earnings inequality during the period of rising wage inequality in the early 1980 s working couples have positively correlated labor market outcomes which are almost entirely attributable to permanent factors an intertemporal family labor supply model with this feature is used to estimate labor supply elasticities for husbands of 0 05 and wives of 0 40 this implies that labor supply explains little of the rising annual earnings inequality for married men but over 20 percent of the rise in family inequality and 50 percent of the modest rise in female inequality

welfare transfers in two parent families labor supply and welfare participation under afdc up this paper examines the effect of cash transfers and food stamp benefits on family labor supply and welfare participation among two parent families the aid to families with dependent children unemployed parent program has provided cash benefits to two parent households since 1961 despite recent expansions little is known about the program s effect on labor supply and welfare participation i develop a model of family labor supply in which hours of work for the husband and wife are chosen to maximize family utility subject to a family budget constraint accounting for afdc up benefits and other tax and transfer programs the husband s and wife s labor supply decisions are restricted to no work part time work and full time work maximum likelihood techniques are used to estimate parameters of the underlying hours of work and welfare participation equations the estimates are used to determine the magnitude of the work disincentive effects of the afdc up program and to simulate the effects of changes in afdc up benefit and eligibility rules on family labor supply and welfare participation the results suggest that labor supply and welfare participation among two parent families are highly responsive to changes in the benefit structure under the afdc up program

changes in male labor supply and wages in the 1980s both wages and labor supply of poorly educated men fell substantially relative to those of educated men some observers have interpreted this positive association between changes in w

nonparametric estimation of the impact of taxes on female labor supply this paper proposes a simple extension of nonparametric estimation methods for nonlinear budget set models derived in blomquist and newey 2002 to censored dependent variables the nonparametric method is applied to estimate female labor supply elasticities using data on married women from the 1985 and 1989 waves of the panel study of income dynamics exploiting the substantial variation in budget sets caused by the tax reform act of 1986 as a source of identification the estimated wage elasticities from this new method are 0 56 overall and 0 27 on the intensive margin the income elasticity estimates are close to 0 67 overall and 0 13 on the intensive margin compared with the linear labor supply model the estimated elasticities are usually larger for the nonparametric specifications that account for nonlinear budget sets copyright 2010 john wiley sons ltd

family labor supply and the timing of cash transfers evidence from the earned income tax credit abstract this paper exploits the unique disbursement timing and benefit rules of the earned income tax credit eitc to provide new evidence on how families adjust their labor supply in response to receiving anticipated cash transfers i find that income seasonality caused by eitc receipt leads to changes in the intra year labor supply patterns of married women on average receiving a 1 000 payment significantly reduces the proportion of married women who work by 1 3 percentage points in the month when the eitc is received additionally this labor supply response is mainly driven by those who are secondary earners or liquidity constrained

what has been learned about labor supply in the past twenty years the main advance in the study of labor supply in the past 20 years has come in recognizing and interpreting the variety of different labor supply functions that coexist in the empirical literature a crucial theoretical distinction with important empirical payoff is that between labor supply choices at the extensive margin i e labor force participation and employment choices and choices at the intensive margin i e choices about hours of work or weeks of work for workers another important distinction is the one between a descriptive labor supply function and a structural supply function that can be the basis for out of sample policy investigations concerning responses to tax and welfare programs and evaluations of welfare losses a full understanding of the participation hours dichotomy leads to an appreciation of the importance of the problem of selection bias what is the wage to impute to a nonworking person these distinctions are a legacy of the research conducted on labor supply over the past 20 years many important empirical questions have been addressed i how strong are the effects of taxes welfare and transfer programs on labor supply ii how important is intertemporal substitution can life cycle labor supply models explain business cycle labor supply behavior iii has the consensus view of the 1960 s of high labor supply elasticities for married women and low labor supply elasticities for married men held up all of the empirical evidence assembled on labor supply must be called into question in the light of important research on the basic quality of the data conducted by analysts at the university of michigan i discuss this evidence in a concluding section except for my discussion of measurement issues i focus only on the major discoveries about which a general consensus has emerged

estimating labour supply responses using tax reforms the 1980 s tax reforms and the changing dispersion of wages offer one of the best opportunities yet to estimate labor supply effects nevertheless changing sample composition aggregate shocks the changing composition of the tax paying population and discontinuities in the tax system create serious identification and estimation problems we develop grouping estimators that address these issues our results reveal positive and moderately sized wage elasticities we also find negative income effects for women with children

estimating the effect of unearned income on labor supply earnings savings and consumption evidence from a survey of lottery players this paper provides empirical evidence about the effect of unearned income on earnings consumption and savings using an original survey of people playing the lottery in massachusetts in the mid 1980 s the effects of the magnitude of lottery prizes on economic behavior are analyzed the critical assumption is that among lottery winners the magnitude of the prize is randomly assigned it is found that unearned income reduces labor earnings with a marginal propensity to consume leisure of approximately 11 percent with larger effects for individuals between 55 and 65 years old after receiving about half their prize individuals saved about 16 percent

changes in the labor supply behavior of married women 1980 2000 using march current population survey data we investigate married women s labor supply from 1980 to 2000 we find a large rightward shift in their labor supply function for annual hours in the 1980s with little shift in the 1990s these shifts account for most of the slowdown in the growth of labor supply during this period a major development was the dramatic decrease in the responsiveness of married women s labor supply to their own and husbands wages their own wage elasticity fell by 50 56 while their cross wage elasticity fell by 38 47 in absolute value

the implications of increasing economic openness for real wages in developing countries 1973 1990 abstract our study shows that increasing economic openness is neither necessarily good nor necessarily bad for real wage growth in developing countries economic growth investment share growth and productivity growth not export share growth are the determinants of real wage growth we also find that the story of wage determination changed in the 1980s compared to the 1970s this change may be due to the implications of heightened competitive pressures in the world market or it may be the result of the debt crisis the main policy implication of our findings is that governments who want to promote growth and the living standards of their workers have to focus explicitly and primarily on increasing investment and productivity growth

small sample bias in synthetic cohort models of labor supply this paper investigates small sample biases in synthetic cohort models repeated cross sectional data grouped at the cohort and year level in the context of a female labor supply model i use the current population survey to compare estimates when group sizes are extremely large to those that arise from randomly drawing subsamples of observations from the large groups i augment this approach with monte carlo analysis so as to precisely quantify biases and coverage rates in this particular application thousands of observations per group are required before small sample issues can be ignored in estimation and sampling error leads to large downward biases in the estimated income elasticity copyright 2007 john wiley sons ltd

behavioural response to ui reform in constrained and unconstrained models of labour supply this paper investigates how taking account of demand side constraints affects estimated models of labor supply and hence predicted behavioral responses to unemployment insurance reform in canada constrained and unconstrained labor supply equations are estimated for single men and women using microdata from the 1982 survey of consumer finance detailed modeling of the impact of the canadian unemployment insurance program on individual budget constraints enables the simulation of behavioral responses to the unemployment insurance reform proposals of the forget and macdonald commissions results indicate that in a high unemployment economy labor supply responses will be negligible

family labour supply and fertility a two regime model the central hypothesis of the new micro economics of fertility was examined i e because children are female time intensive fertility is inversely related to the mothers wage a theoretical model of lifetime family labor supply and completed fertility which forms the basis for the subsequent empirical investigation is presented empirical estimates of the model are provided using 1971 canadian census data the 1 period model of completed family size and lifetime labor supply indicates that fertility and labor supply behavior of families where the wife participates in the labor market will differ from that of families with never participating wives the systematic differences arise because families with nonworking wives face the additional binding constraint of an inflexible supply of wifes time to the home a comparison of these 2 regimes allows inferences concerning the female time intensity of children and the substitutability of husbands and wifes time in the context of the 1 period model the relevant criterion for separating families into the 2 regimes is the lifetime rather than current participation status the evidence suggests that when this procedure is followed much doubt is cast on the conventional wisdom that children are female time intensive the usual inverse relation found between wifes wage or education and completed family size appears to be the result of a complex interaction between wage rates lifetime labor force participation and fertility some support is found for complementarity between the home time of the husband and wife but the evidence is not totally consistent results of the female participation equation strongly suggest complementarity proxies for the husbands lifetime labor supply suggest weak or zero complementarity when the sample is split by current participation of the wife rather than lifetime participation then the results support conventional wisdom concerning the female time intensity of children and replicate kneisners finding of complementarity between husband and wifes time reconciling these differences within the framework of the 1 period model is difficult since it yields no predictions concerning current variables yet since the wifes lifetime participation is the correct criterion for allocating families to the 2 regimes under the 1 period model doubt must remain concerning the female time intensity of children until the current lifetime results are reconciled

export processing zones in the dominican republic transforming manufactures into commodities this paper examines the performance of export processing zones in the dominican republic it shows that in specializing in unskilled labor intensive export processing in the context of competitive devaluations between central american countries the dominican republic has experienced immiserizing employment growth in these circumstances the export of labor intensive manufactures is akin to that of primary commodities exporting countries which rely on unskilled labor and which fail to make the transition to higher value added production exports are thus likely to experience declining terms of trade the conclusions of this case study are considered to have wider relevance to world bank and international monetary fund inspired structural adjustment programs in the region

the incredible shrinking elasticities married female labor supply 1978 2002 this paper demonstrates the extent to which married women s labor supply elasticities have changed over the past quarter century estimates from march current population survey data suggest that these elasticities have decreased substantially by 60 percent for the hours wage elasticity from 0 36 to 0 14 70 percent for the hours income elasticity from 0 053 to 0 015 95 percent for the participation wage elasticity from 0 66 to 0 03 and 60 percent for the participation income elasticity from 0 13 to 0 05 changing demographic characteristics explain little of the drop in these elasticities suggesting that preferences toward work have changed across birth cohorts

preschoolers enrolled and mothers at work the effects of universal prekindergarten three states recently introduced universal prekindergarten programs offering free preschool to all age eligible children policy makers in many other states are promoting similar programs using restricted access data from the census together with birthday based eligibility cutoffs i employ a regression discontinuity framework to estimate the effects of universal pre k availability on overall preschool enrollment and maternal labor supply universal pre k availability increases statewide preschool enrollment by about 14 but has little effect on the labor supply of most women

nonparametric structural estimation of labor supply in the presence of censoring this paper extends the nonparametric structural method to estimate labor supply developed by blomquist and newey 2002 to handle cases in which there are individuals who do not work the method is then applied to married women in sweden from 1973 to 1999 i find an uncompensated wage elasticity of 0 98 and an income elasticity of 0 10 with the participation margin accounting for one third of the wage elasticity and two thirds of the income elasticity the elasticities vary however a lot over time due to differences in tax systems and demographics i also find results consistent with tax rates being around the net government revenue maximizing rates

the impact of transport and transaction cost reductions on food markets in developing countries evidence for tempered expectations for burkina faso reductions in transport and transaction costs are expected to have a major effect on the functioning of food markets in developing countries for burkina faso this is a relevant issue as it may have important consequences for the food markets in urban and rural deficit areas a partial equilibrium model is presented to analyze the short term effects of reduced costs on price formation inter regional cereal trade and farmers and traders storage strategies our results show that the high expectations with regard to the direct effects of cost reductions on food prices and food availability require some nuance the effects of a reduction of transport costs will be small moreover also the unintended negative consequences on the competitive position of farmers and traders in other regions that do not profit from road construction should be taken into account finally it is concluded that only if transport and transaction costs are reduced simultaneously will both the consumers and farmers benefit significantly c 2004 elsevier b v all rights reserved

why are u s women decreasing their labor force participation if their wages are rising given the traditional interpretation of women s labor force participation rate lfpr trends as movements along a positively sloped labor supply curve it is surprising that the recent downward trend in u s women s lfpr has occurred over a period when women s real wages were commonly believed to be rising i find that almost two thirds of the decline since 2000 is attributable to aging of the adult female population the remainder due to declining labor force participation for women under 55 becomes less puzzling in light of my evidence that the wage education locus faced by women actually may have worsened since 2000 jel j21 j31 j82

evaluation of four tax reforms in the united states labor supply and welfare effects for single mothers an emerging consensus is that labor force participation is more responsive to taxes and transfers than hours worked to understand the implications of participation responses for the welfare analysis of tax reform this paper embeds this margin of labor supply in an explicit welfare theoretic framework we apply the framework to examine the welfare effects on single mothers in the united states following four tax acts passed in 1986 1990 1993 and 2001 we propose a simulation method combining features of fully structural microsimulation studies and simple deadweight loss calculations our approach accounts for the observed heterogeneity in the microdata but is simple to implement because we do not need to specify utility functions and estimate utility parameters we find that each of the four tax acts created substantial welfare gains and that the gains were concentrated almost exclusively on the participation margin our results imply that standard approaches not modeling the participation decision can make large errors

redistribution of social benefits from advances in extension and research in the tanzanian maize industry abstract this study determined consumer and producer welfare gains from advances in extension and research in the maize industry of tanzania to determine how a national taxing schedule should be determined it was found that for an off farm marketable surplus of 40 consumers and producers gain equally while for an off farm marketable surplus of 60 consumers realize 75 of the welfare benefits this suggests that consumers and producers should share equally in a revenue generating tax for funding maize research and extension programs however for large producers with a marketable surplus of 60 or more their tax should decrease proportionally to the amount sold alternatively if taxed equally large scale producers should receive some form of compensation through direct government payments

the impact of child care costs on the labour supply of married mothers evidence from canada this paper provides estimates for canada of the impact of childcare costs on the labor supply of married mothers this is done by linking two microdata sources the 1988 canadian national child care survey and the 1988 labour market activity survey the key results show that the market wage and childcare costs have respectively a significant positive and negative impact on both hours of work and the labor force participation decision by married mothers the childcare cost elasticities for labor force participation and hours of work are reported to be 0 38 and 0 32 respectively

assortative mating and female labor supply this paper investigates married women s hours worked disaggregated by the husband s wage decile in the united states this pattern has changed from downward sloping to hump shaped we show that this development can be explained within a standard household model of labor supply when taking into account trends in assortative mating a quantitative analysis of our model shows that female wage growth and decreasing fertility are primarily responsible for the overall increase in wives hours since the 1970s the fact that the most pronounced increases are observed for wives married to high wage men is a result of trends in assortative mating

family labor supply with taxes over the period 1960 1983 the proportion of federal tax revenue raised by taxation of labor supply has risen from 57 77 percent in this paper we specify and estimate a model of family labor supply which treats both federal and state taxation husbands and wives labor supply are treated jointly rather than in aseparate manner as in previous research a method to calculate the virtual wage for nonworking spouses is used within a utility maximizing framework to treat correctly the joint family labor supply decision joint family efforts are found to be important the efficiency cost deadweight loss of labor taxation is estimated to be 29 6 of tax revenue raised the effect of the new 10 deduction to ease the marriage tax for working spouses leads to a prediction of 3 8 increase in wives labor supply and a 9 decrease in husbands labor supply overall taxes paid are predicted to decrease by 3 4 this abstract was borrowed from another version of this item

a spatial analysis of maize marketing policy reforms in zambia in this study we analyze recent and proposed maize marketing reforms in zambia to capture the effects of changing transport systems we use a continuous space model in place of the traditional point representation model of takayama and judge this method permits us to use prereform data on supply demand and transport costs to infer both intra and interregional effects of liberalization and shows that the welfare gains from liberalization are larger than commonly thought these results provide policy makers with estimates of the magnitude of change associated with alternative reform programs beyond what would be available from a conventional approach

taxes and the labor market participation of married couples the earned income tax credit a distinguishing feature of recent changes to the us system of public assistance is its increasing focus on working families and reliance on the tax system to transfer dollars to needy families after a decade in near total obscurity the earned income tax credit eitc was expanded to become the largest cash transfer program for lower income families with children advocates of the eitc argue that unlike traditional welfare the credit helps promote both the values of family and work indeed empirical evidence consistent with economic theory suggests that the eitc promotes employment among eligible unmarried women with children to target benefits to lower income families however the eitc is based on family income leading to traditional welfare type disincentives for most eligible secondary earners in fact the eitc is likely to reduce overall family labor supply among married couples this paper examines the labor force participation response of married couples to eitc expansions between 1984 and 1996 the effect of the credit is estimated using both quasiexperimental and traditional reduced form labor supply models results from both models show the same qualitative conclusion that the eitc expansions reduced total family labor supply of married couples in all cases we find a decline in labor force participation by married women that more than offsets any rise in participation by their spouses while the labor force participation rate of married men increased by about 0 2 percentage points that of married women decreased by just over a full percentage point these aggregate effects mask substantial heterogeneity in the population women facing the strongest disincentives were more than 2 percentage points less likely to work after the expansions these findings imply that the eitc is effectively subsidizing married mothers to stay home and therefore have implications for the design of the program d 2003 elsevier b v all rights reserved

the sensitivity of an empirical model of married women s hours of work to economic and statistical assumptions this study undertakes a systematic analysis of several theoretic and statistical assumption s used in many empirical models of female labor supply using a singl e data set psid 1975 labor supply data the author is able to replic ate most of the range of estimated income and substitution effects fo und in previous studies in this field he undertakes extensive specif ication tests and finds that most of this range should be rejected du e to statistical and model misspecifications the two most important assumptions appear to be the tobit assumption used to control for sel f selection into the labor force and exogeneity assumptions on the wi fe s wage rate and her labor market experience copyright 1987 by the econometric society

wages and participation during the last 25 years annual hours worked by prime aged men fell by the equivalent of six 40 hour workweeks the reduction was more pronounced among those younger than among mid age workers among black men than among white men and among those with less schooling thus hours worked not only fell but showed increased dispersion increases that paralleled the growth in wage dispersion that has become so familiar to students of trends in wages the argument advanced here is that the correspondence is not coincidental the changes in hours worked are simply the labor supply responses that follow the changes in the structure of wages

collective labor supply and welfare the paper develops a general collective model of household labor supply in which agents are characterized by their own possibly altruistic preferences and household decisions are only assumed to be pareto efficient an alternative interpretation is that there are two stages in the internal decision process agents first share nonlabor income according to some given sharing rule then each one optimally chooses his or her own labor supply and consumption this setting is shown to generate testable restrictions on labor supplies moreover the observation of labor supply behavior is sufficient for recovering individual preferences and the sharing rule up to a constant finally the traditional tools of welfare analysis can be adapted to the new setting

taxing women a macroeconomic analysis based on well known evidence on labor supply elasticities several authors have concluded that women should be taxed at lower rates than men we evaluate the quantitative implications and merits of this proposition relative to the current system of taxation setting a proportional tax rate on married females equal to 4 8 increases output and married female labor force participation by about 3 9 3 4 and 6 9 4 0 respectively gender based taxes improve welfare and are preferred by a majority of households nevertheless welfare gains are higher when the u s tax system is replaced by a proportional gender neutral income tax 2011 published by elsevier b v

child care costs and the employment decision of women canadian evidence the authors estimate the joint decision for women with preschool children to engage in paid employment and to purchase market forms of child care the results confirm those found in most u s studies indicating that child care costs exert a significant negative effect on the labor supply of women with children and on their decision to purchase child care as well the expected wage of the mother exerts a significant positive impact on both the decision to purchase market forms of child care and the decision to engage in paid unemployment

new estimates of labour supply elasticities for married women in canada 1996 2005 in this article we estimate income and substitution labour supply and participation elasticities for canadian married women using data from the survey of labour and income dynamics 1996 2005 we use the canadian tax and credit simulator ctacs and detailed information on the structure of income at the household level to compute the marginal tax rates faced by each individual we then use these marginal tax rates to compute net own wage spouse wage and nonlabour income we show how the magnitude of the estimated elasticities varies depending on whether net or gross wages and income are used in the estimation procedure and quantify biases caused by using average tax rates instead of marginal tax rates finally because marginal tax rates vary significantly over the sample we use quantile regressions to compare elasticities at different points of the hours distribution overall our results show that public policies now have on average less scope for influencing hours of work than 10 years ago howev

factor proportions and relative wages the supply side determinants of wage inequality supply side factors may contribute to rising wage inequality first certain changes in the supply of skills allegedly exacerbate wage inequality women s increased labor force participation and increased immigration are the leading candidates both allegedly reduce the wages of less skilled men however immigration s impact on wage inequality has been minor and the effects of women s participation is inconclusive second in evaluating the likelihood that human capital investment will mitigate future inequality evidence suggests that rising returns to education have increased the proportion of young people attending college limiting the growth of inequality among high wage workers
