female labour supply and marital status decisions a life cycle model this paper studies the interdependence between and the determinants of life cycle marital status and labour force participation decisions of women a dynamic utility maximization model is presented and estimated using longitudinal data on women from the panel study of income dynamics the mle method employed involves solving a dynamic programming problem further a minimum distance estimator is proposed which allows for the incorporation of wage data in a computationally simple way the estimates are used to predict changes in the life cycle patterns of employment marriage and divorce due to differences in education race the female s earnings and her potential husband s earnings the estimation results indicate that the utility gains to marriage are decreasing in the female s wage rate and increasing in her potential husband s earnings while the opposite is found for gains to working ignoring the endogeneity of marital status decisions is shown to lead to an underestimation of own and husband s wage effects on female labour supply

affirmative action in higher education how do admission and financial aid rules affect future earnings this paper addresses how changing the admission and financial aid rules at colleges affects future earnings i estimate a structural model of the following decisions by individuals where to submit applications which school to attend and what field to study the model also includes decisions by schools as to which students to accept and how much financial aid to offer simulating how black educational choices would change were they to face the white admission and aid rules shows that race based advantages had little effect on earnings however removing race based advantages does affect black educational outcomes in particular removing advantages in admissions substantially decreases the number of black students at top tier schools while removing advantages in financial aid causes a decrease in the number of blacks who attend college

the hausman macurdy controversy why do the results differ across studies the two perhaps most influential empirical labor supply studies carried out in the united states in recent years hausman 1981 and macurdy green and paarsch 1990 report sharply contradicting labor supply estimates in this paper we show that the seemingly irreconcilable views on the size of work disincentive effects and welfare losses can be attributed to the use of differing nonlabor income and wage measures in the two studies monte carlo experiments suggest that the wage measure adopted by macurdy green and paarsch 1990 might cause a severely downward biased wage effect such that data falsely refute the basic notion of utility maximization

the effect of unions on the structure of wages a longitudinal analysis this paper studies the effects of unions on the structure of wages using an estimation technique that explicitly accounts for misclassification errors in reported union status and potential correlations between union status and unobserved productivity the econometric model is estimated separately for five skill groups using a large panel data set formed from the u s current population survey the results suggest that unions raise wages more for workers with lower levels of observed skills in addition the patterns of selection bias differ by skill group among workers with lower levels of observed skill unionized workers are positively selected whereas union workers are negatively selected from among those with higher levels of observed skill despite a large and sophisticated literature there is still substantial disagreement over the extent to which differences in the structure of wages between union and nonunion workers represent an effect of trade unions rather than a consequence of the nonrandom selection of unionized workers over the past decade several alternative approaches have been developed to control for unobserved heterogeneity between union and nonunion workers 2 one method that has been successfully applied in other areas of applied microeconometrics is the use of longitudinal data to measure the wage gains or losses of workers who change union status unfortunately longitudinal estimators are highly sensitive to measurement error even a small fraction of misclassified union status changes can lead to significant biases if the true rate of mobility between union and nonunion jobs is low this sensitivity led lewis 1986 to essentially dismiss the longitudinal evidence in his landmark survey of union wage effects in this paper i present some new evidence on the union wage effect based on a longitudinal estimator that explicitly accounts for misclassification errors in reported union status the estimator uses external information on union status misclassification rates along with the reduced form coefficients from a multi variate regression of wages on the observed sequence of union status indicators to isolate the causal effect of unions from any selection biases introduced by a correlation between union status and the permanent component of unobserved wage heterogeneity recognizing that unions may raise wages more or less for

the effect of work experience on female wages and labour supply this paper develops and implements a semiparametric estimator for investigating with panel data the importance of human capital and time nonseparable preferences to females when aggregate shocks are present it provides a set of conditions for making statistical inferences about agents expectations of their correlated future choices from a short panel under the assumption that observed allocations are pareto optimal a dynamic model of female labour supply and participation is estimated in which experience on the job raises future wages and time spent off the job in the past directly affects current utility or indirectly through productivity in the nonmarket sector

from theory to practice canadian economists contributions to public finance we survey canadian economists contributions to the field of public finance from the mid 1980s to 2016 we highlight the development and extension of the models and tools of public economics and the empirical studies that have deepened our understanding of the efficiency and distributional issues over a wide range of public finance issues we also highlight contributions to the development of policies through commissioned reports and the important role that canadian institutions the canadian tax foundation the think tanks and the federal and provincial departments of finance have played in shaping tax and fiscal policies de la theorie a la pratique contributions des economistes canadiens a la finance publique on examine les contributions des economistes canadiens au domaine de la finance publique du milieu des annees 1980 a 2016 on souligne le developpement et l extension des modeles et des outils d economie publique et les etudes empiriques qui ont aide a approfondir notre comprehension des enjeux d efficacite et de distribution dans un vaste eventail de questions de finance publique on souligne aussi les contributions des rapports commandites au developpement de politiques publiques ainsi que le role important d institutions canadiennes l association canadienne d etudes fiscales les groupes d experts ainsi que les ministeres des finances du gouvernement federal et des gouvernements provinciaux dans le design des politiques fiscales

assessing policies to equalize opportunity using an equilibrium model of educational and occupational choices abstract the inter generational correlation of education in the u s is tremendous for instance in psid data from 1990 young males with college educated parents had a 70 chance of attending college but those with high school drop out parents had only a 15 chance in this paper we analyze the impact of college attendance bonus schemes designed to increase college attendance rates and pv of lifetime income of youth from disadvantaged backgrounds of course policies that increase the supply of skilled labor may reduce the college wage premium see heckman et al heckman james lochner lance and taber christopher explaining rising wage inequality explorations with a dynamic equilibrium model of labor earnings with heterogeneous agents review of economic dynamics 1 1998a 1 58 heckman james lochner lance and taber christopher general equilibrium treatment effects a study of tuition policy american economic review 88 2 1998b 381 386 this may have the unintended consequence of wiping out most of the gains to the targeted groups the strength of such equilibrium effects on wages depends on the substitutability between different types of labor thus it is important to evaluate education subsidies within an equilibrium framework that allows for flexible patterns of substitution across factor inputs this is exactly what we do here using an overlapping generations equilibrium model of the u s labor market fit to psid data from 1968 to 1996 the model allows for imperfect substitution among types of labor differentiated by education gender age and ten 1 digit level occupations a much finer differentiation than has been considered in prior work we find that very large college attendance bonuses are necessary to equate college attendance rates between youth whose parents had only high school degrees or were high school dropouts and youth whose parents attended at least some college the size of these bonuses far exceeds any reasonable measure of college costs suggesting the costs the bonuses overcome are primarily psychic or effort costs for example youth from disadvantaged backgrounds may be poorly prepared for college this suggests that bonuses targeted at college age youth are probably a very inefficient way to reduce inequality earlier intervention is likely called for

the effect of income taxation on labor supply in the united states the effect of income taxation on the labor supply of prime age married men and women in the united states is examined using econometric methods similar to those used in the influential work of jerry hausman male labor supply is found to be relatively invariant to the net wage and virtual income in all specifications estimated the estimated impact of taxation on the labor supply of married women depends critically on the method used to estimate the labor supply function estimated net wage and virtual income elasticities are considerably larger when data on nonparticipants are included than when the estimation is conducted conditional on hours being greater than zero

new evidence on labor supply employment versus hours elasticities by sex and marital status using the tri annual micro panel data of the survey of income and program participation we estimate fixed effects labor supply models separating the extensive and intensive margins the employment elasticity is 0 6 for single men versus 1 1 for married men the employment elasticity is 2 4 for single women versus 1 8 for married women the compensated hours worked elasticity is 0 4 for employed single and married men and 0 7 for employed single and married women the implied aggregate employment elasticity of 1 5 and hours per employee elasticity of 0 5 indicate employment fluctuations account for three fourths of wage induced variation in labor hours

micro and macro elasticities in a life cycle model with taxes we build a life cycle model of labor supply that incorporates changes along both the intensive and extensive margin and use it to assess the consequences of changes in tax and transfer policies on equilibrium hours of work we find that changes in taxes have large aggregate effects on hours of work moreover we find that there is no inconsistency between this result and the empirical finding of small labor elasticities for prime age workers in our model micro and macro elasticities are effectively unrelated our model is also consistent with other cross country patterns

bounds on elasticities with optimization frictions a synthesis of micro and macro evidence on labor supply how can price elasticities be identified when agents face optimization frictions such as adjustment costs or inattention i derive bounds on structural price elasticities that are a function of the observed effect of a price change on demand the size of the price change and the degree of frictions the degree of frictions is measured by the utility losses agents tolerate to deviate from the frictionless optimum the bounds imply that frictions affect intensive margin elasticities much more than extensive margin elasticities i apply these bounds to the literature on labor supply the utility costs of ignoring the tax changes used to identify intensive margin labor supply elasticities are typically less than 1 of earnings as a result small frictions can explain the differences between micro and macro elasticities extensive and intensive margin elasticities and other disparate findings pooling estimates from existing studies i estimate a hicksian labor supply elasticity of 0 33 on the intensive margin and 0 25 on the extensive margin after accounting for frictions

the retirement incentive effects of canada s income security programs canada has a large income security system for retirement that provides significant and widely varying disincentives to work at older ages we provide an empirical analysis of the retirement incentives of the canadian income security system using a new administrative database we find that the work disincentives inherent in the canadian income security system have significant impacts on retirement this suggests that program reform can play a role in responses to fiscal pressures we also demonstrate the importance of controlling for lifetime earnings in retirement models specifications without these controls overestimate the effects of the income security

micro and macro labor supply elasticities a reassessment of conventional wisdom the response of aggregate labor supply to various changes in the economic environ ment is central to many economic issues especially the optimal design of tax policies conventional wisdom based on studies in the 1980s and 1990s has long held that the analysis of micro data leads one to conclude that aggregate labor supply elasticities are quite small in this paper we argue that this conventional wisdom does not hold up to empirically reasonable and relevant extensions of simple life cycle models that served as the basis for these conclusions in particular we show that several pieces of conventional wisdom fail in the presence of human capital accumulation or labor supply decisions that allow for adjustment along both the extensive and intensive margin we conclude that previous estimates of small labor supply elasticities based on micro data are fully consistent with large aggregate labor supply elasticities jel d91 e24 j22

fiscal deficits output growth and inflation targets in ghana abstract inflation appears to be the macro problem for which no antidote has been found under the economic recovery programme it is possible that either a wrong diagnosis has been made of the problem or that certain factors within the economy are preventing inflation from staying within target levels using an error correction model ecm the paper estimates an inflation equation for ghana the convenience of this model is in the fact that all the data series exhibit an autoregressive scheme of order one that is they are i 1 series in such an instance the granger engle theorem shows that the ecm provides the most efficient model further the ecm unveils some of the short run dynamics which are missing in other estimation techniques the results of the econometric regression show that inflation in ghana either in the long run or short run is influenced more by output volatility than by monetary factors an examination is made of the consistency of fiscal deficit the hypothesis is that an unsustainable fiscal policy would make government miss some macroeconomic targets it is shown that in 1985 and 1989 fiscal policy was consistent inflation was well within target in 1985 for 1986 1988 the government did not maintain consistent fiscal deficits and inflation in those years was well above targets it is recommended that to control inflation in ghana more attention should be paid to supply factors further government should pursue consistent fiscal policies

tax subsidies and household saving evidence from canada targeted tax based saving incentives can be a powerful tool for promoting household and national saving this study examines the effect of the cancellation of the registered home ownership savings plan rhosp a canadian tax subsidized saving program on household saving the cancellation provides exogenous variation in eligibility for the subsidy that is uncorrelated with householdspecific heterogeneity in saving behavior the empirical analysis suggests that the subsidy had a substantial impact on saving each dollar contributed to the program represented 56 93 and 20 57 cents of new household and national saving respectively

the effect of income taxation on the labor supply of married men in sweden abstract this paper presents labor supply functions estimated on a sample of prime age swedish males the model used takes account of the nonlinear character of individuals budget sets caused by the progressive income tax it also allows preferences to vary between individuals calculations with the estimated functions using a partial equilibrium framework indicate a sizeable effect of the income tax on hours of work the average expected deadweight loss of the income tax is found to be approximately 20 percent of tax revenue

the effect of taxes on male and female labor supply in sweden this paper estimates labor supply functions for married men and women in sweden using data from 1980 taking account of the complete form of individuals budget constraints both linear and quadratic supply functions are estimated with and without random preferences a novel feature is that for women the wage rate and labor supply functions are estimated simultaneously using a full information maximum likelihood method this method yields substantially larger wage and income elasticities than does the previously used two step methods another result is that the quadratic supply function wage elasticities for men and women are virtually the same if the elasticities are evaluated at the same net wage rate and hours of work for men and women the estimated functions are used to calculate the effect of tax reforms

a life cycle consistent empirical model of family labour supply using cross section data this paper estimates a utility maximising model of the joint determination of male and female labour supplies using a sample of married couples from the u k family expenditure survey the emphasis is on the estimation of within period preferences that are consistent with intertemporal two stage budgeting under uncertainty however the approach we adopt provides an alternative method of estimating certain aspects of life cycle behaviour to the fixed effects constant approach of heckman and macurdy 1980 macurdy 1981 and browning deaton and irish 1985 moreover it relaxes some of the underlying restrictions that are implicit in these constant models under uncertainty

consumption inequality and family labor supply we examine the link between wage and consumption inequality using a life cycle model incorporating consumption and family labor supply decisions we derive analytical expressions for the dynamics of consumption hours and earnings of two earners in the presence of correlated wage shocks nonseparability progressive taxation and asset accumulation the model is estimated using panel data for hours earnings assets and consumption we focus on family labor supply as an insurance mechanism and find strong evidence of smoothing of permanent wage shocks once family labor supply assets and taxes are properly accounted for there is little evidence of additional insurance jel d12 d14 d91 j22 j31

a structural model of multiple welfare program participation and labor supply work on estimating the labor supply effects of high marginal tax rates in welfare programs has been hindered by the difficulty of estimating the effects of participation in multiple welfare programs simultaneously the authors solve this problem by applying methods of simulation estimation to a model of labor supply and multiple program participation the results show asymmetric wage and tax rate effects with fairly large wage elasticities of labor supply but very inelastic responses to moderate changes in cumulative marginal tax rates implying that high welfare tax rates do not necessarily induce major reductions in work effort copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

the role of labor and marriage markets preference heterogeneity and the welfare system in the life cycle decisions of black hispanic and white women using data from the nlsy79 we structurally estimate a dynamic model of the life cycle decisions of young women the women make sequential joint decisions about school attendance work marriage fertility and welfare participation we use the model to perform counterfactual simulations designed to shed light on three questions 1 how much of observed minority majority differences in behavior can be attributed to differences in labor market opportunities marriage market opportunities and preference heterogeneity 2 how does the welfare system interact with these factors to augment those differences 3 how can new cohorts that grow up under the new welfare system temporary aid for needy families be expected to behave compared to older cohorts

balance of payments output and prices in tanzania abstract this paper examines the relationship between changes in international reserves and changes in output prices and monetary balances in tanzania using annual data for 1962 86 a short run macroeconomic model of the balance of payments is formulated and estimated in which output and prices are endogenized and the behaviors of the monetary and fiscal authorities are explicitly modeled the estimation results are used to examine the relative effectiveness of alternative policy instruments on the key macroeconomic variables of the model the monetary variables appear to have played a relatively significant role in the development of prices but they were only marginally significant in the process of balance of payments adjustment the simulation results indicate that a tradeoff existed between faster economic growth and better balance of payments performance

an economic model of welfare stigma perhaps the most basic assumption of the economic theory of consumer demand is that more is better than less virtually all of the major propositions of consumer theory can in a certain sense be derived from the assumption that goods are good interestingly however this tenet seems to be violated by the behavior of many individuals in the low income population for many turn out to be eligible for a positive welfare benefit but do not in fact join the welfare rolls for example it has been estimated that in 1970 only about 69 percent of the families eligible for afdc aid to families with dependent children participated in the program see richard michel 1980 the corresponding percentage for afdc u the program for which families with an unemployed male are eligible was only 43 percent and the participation rate in the food stamp program was only 38 percent see maurice mcdonald 1977 this phenomenon has puzzled many investigators because such individuals do not locate on the boundaries of their budget sets consequently most investigators ignore the problem when studying the effects of welfare programs on behavior in this paper this seemingly irrational rejection of an increase in income is modeled as resulting from welfare stigma that is from disutility arising from participation in a welfare program per se 1 the existence of stigma has been amply documented in the sociological literature patrick horan and patricia austin 1974 lee rainwater 1979 where interviews of recipients have often uncovered feelings of lack of self respect and negative self characterizations from participation in welfare nevertheless this phenomenon has not been modeled and many questions consequently remain when is the disutility of participation strong enough to prevent participation shouldn t we expect individuals to weigh the disutility of participation against the potential benefit in their decisions what is the elasticity of participation with respect to the potential benefit also in a slightly different vein how are the work disincentives of welfare affected by stigma these questions have been given scant attention by economists yet they are crucial for our ability to predict the impact of various welfare programs on the lowincome population here these questions are addressed by modeling nonparticipation as a utility maximizing decision the model is developed and estimated for the afdc program 2 the model posits an individual utility function containing not just disposable income but

child care choices and children s cognitive achievement the case of single mothers we evaluate the effect of child care versus maternal time inputs on child cognitive development using single mothers from the nlsy79 to deal with nonrandom selection of children into child care we exploit the exogenous variation in welfare policy rules facing single mothers in particular the 1996 welfare reform and earlier state level policy changes generated substantial increases in their work child care use we construct a comprehensive set of welfare policy variables and use them as instruments to estimate child cognitive ability production functions in our baseline specification we estimate that a year of child care reduces child test scores by 2 1

labor supply and taxes a survey i survey the male and female labor supply literatures focusing on implications for effects of wages and taxes for males i describe and contrast results from three basic types of model static models especially those that account for nonlinear taxes life cycle models with savings and life cycle models with both savings and human capital for women more important distinctions are whether models include fixed costs of work and whether they treat demographics like fertility and marriage and human capital as exogenous or endogenous the literature is characterized by considerable controversy over the responsiveness of labor supply to changes in wages and taxes at least for males it is fair to say that most economists believe labor supply elasticities are small but a sizeable minority of studies that i examine obtain large values hence there is no clear consensus on this point in fact a simple average of hicks elasticities across all the studies i examine is 0 30 several simulation studies have shown that such a value is large enough to generate large welfare costs of income taxation for males i conclude that two factors drive many of the differences in results across studies one factor is use of direct vs ratio wage measures with studies that use the former tending to find larger elasticties another factor is the failure of most studies to account for human capital returns to work experience i argue that this may lead to downward bias in elasticity estimates in a model that includes human capital i show how even modest elasticities as conventionally measured can be consistent with large welfare costs of taxation

the elasticity of taxable income with respect to marginal tax rates a critical review this paper critically surveys the large and growing literature estimating the elasticity of taxable income with respect to marginal tax rates using tax return data first we provide a theoretical framework showing under what assumptions this elasticity can be used as a sufficient statistic for efficiency and optimal tax analysis we discuss what other parameters should be estimated when the elasticity is not a sufficient statistic second we discuss conceptually the key issues that arise in the empirical estimation of the elasticity of taxable income using the example of the 1993 top individual income tax rate increase in the united states to illustrate those issues third we provide a critical discussion of selected empirical analyses of the elasticity of taxable income in light of the theoretical and empirical framework we laid out finally we discuss avenues for future research jel h24 h31 j22

estimating intertemporal labour supply elasticities using structural model in this paper the author proposes empirical models where both the intertemporal substitution elasticity and the elasticities measuring the impact of different wage profiles are estimated taking into account the restrictions derived from utility maximization she considers models assuming a stone geary utility function and also a constant elasticity of substitution across periods function the data used are a sample of men from the michigan panel of income dynamics her estimates support the low intertemporal substitution elasticity found in previous studies the estimates for the uncompensated elasticities are also small copyright 1989 by royal economic society

risk averse behavior in generalized matching pennies games in experimental studies of behavior in 2 2 games with unique mixed strategy equilibria observed choice frequencies are systematically different from mixed strategy nash predictions this paper examines experimental results for a variety of such games and shows that a structural econometric model which incorporates risk aversion into a quantal response equilibrium explains the data very well moreover risk aversion estimates are stable across the different games and are close to those obtained from laboratory and field auction data as well as from individual lottery choice experiments

taxation and the earnings of husbands and wives evidence from sweden i examine the response of husbands and wives earnings to a tax reform in which husbands and wives tax rates changed independently allowing me to examine the effect of both spouses incentives on each spouse s behavior i analyze the large swedish tax reform of 1990 1991 and find that in response to a compensated fall in one spouse s tax rate each spouse s earnings rise i compare these results to those of simplified econometric models used in the typical setting in which independent variation in each spouse s tax rate is unavailable i find that standard econometric specifications may produce substantially biased estimates

estimating the effects of unions on wage inequality in a panel data model with comparative advantage and nonrandom selection this article considers the estimation of the structure of wages in union and nonunion sectors it proposes an estimator that extends standard panel data techniques to the case in which the return to the permanent component of the error term is differently rewarded in the two sectors the econometric model is used to estimate the effect of unions on both the level and the variance of wages in canada the findings indicate that unions increase the average wage of workers and compress the returns to observable measures of skill and to a time invariant unobservable measure of skill

a superior measure of consumption from the panel study of income dynamics abstract this paper provides a simple technique for assigning a measure of total consumption to households in the panel study of income dynamics psid using regressions from the consumer expenditure surveys of 1972 1973 and 1983 linear predictions of total consumption are estimated which are stable over time and explain up to 78 percent of the total variance in consumption

new evidence on taxes and portfolio choice abstract identifying the effect of differential taxation on portfolio allocation requires exogenous variation in marginal tax rates marginal tax rates vary with income but income surely affects portfolio choice directly in systems of individual taxation like canada s couples with the same household income can face different effective tax rates on capital income when labor income is distributed differently within households using this source of variation we find portfolio responses to taxation among more affluent households the estimated effects are statistically significant but economically modest in a placebo test using data from the u s which has joint taxation we find no effect of the intra household distribution of labor income on portfolios

crowd out education and employer contributions to workplace pensions evidence from canadian tax records this study assesses whether workplace pensions help individuals overcome knowledge barriers to saving for retirement using administrative data from canada and exploiting unique features of the pension system i find compelling evidence that each 1 contributed to workplace pensions partially crowds out other retirement saving by approximately 0 50 among interior savers in a regression kink design centering on unionized workers for methodological reasons further analysis indicates active versus passive decisions are influenced by education exploiting compulsory schooling reforms for identification i conclude by showing pension and education reform are both viable mechanisms for boosting saving from a life cycle perspective jel codes e21 h30 i21 j32

life cycle labor supply with human capital accumulation a dynamic model of labor supply under uncertainty with endogenous human capital accumulation is developed and estimated using 1968 81 panel study of income dynamics male panel data given a learning by doing technology for human capital investment and a translog utility function structural parameters for preferences and technology are estimated from the orthogonality conditions implied by the euler equations assuming rational expectations the parameter estimates conform to economic theory simulations of the model suggest that the intertemporal labor supply elasticity with endogenous wages will rise over the lifecycle producing different policy implications than typical models with exogenous wages and constant intertemporal elasticities copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

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

intertemporal substitution in labor supply evidence from micro data the sensitivity of the supply of labor to intertemporal variation in the wage is an important issue in macroeconomics the analysis of social security and pensions and the study of life cycle patterns of work this paper explores two approaches to the measurement of intertemporal substitution that have appeared in the literature the first approach is to use consumption to control for wealth and unobserved expectations about future wages in the labor supply equation the second approach is to estimate a first difference equation for hours in which labor supply from the previous period serves as a control for wealth and wage expectations the results indicate that intertemporal substitution elasticity for married men is positive but small

do only tax incentives matter labor supply and demand responses to an unusually large and salient tax break abstract i explore labor supply responses to an unusually large and salient notch generated by the mini job program in germany using administrative data i document three findings first despite the unusually large magnitude of incentives earnings elasticities are modest even after accounting for frictions second the observed response cannot be fully attributed to labor supply alone rather the observed outcomes are highly dependent on the availability of jobs and so are strongly influenced by labor demand incentives third i show that these firm incentives are likely driven by the fact that mini job workers receive lower fringe benefit payments

anticipated and unanticipated wage changes wage risk and intertemporal labor supply in this article i estimate how labor supply responds to anticipated wage growth unanticipated wage growth and wage risk using the 1989 93 panel section of the bank of italy survey of households income and wealth shiw which collects individual expectations of future wages the use of subjective expectations has several advantages first they provide information on the evolution and riskiness of future wages that the econometrician may never hope to observe moreover this avoids the need for specifying instruments for the growth rate of wages finally forecast errors can be directly controlled for thus avoiding inconsistency in short panels

dynamic labour force participation of married women and endogenous work experience this paper presents and estimates a dynamic model of married women s labour force participation and fertility in which the effect of work experience on wages is explicitly taken into account because current participation alters future potential earnings the investment return to work will be an important factor in the current work decision in any forward looking behavioural model the model is estimated using the national longitudinal surveys mature women s cohort we use the estimates of our model to predict changes in the lifecycle patterns of employment due to changes in schooling fertility husband s income and the magnitude of the experience effect on wages we find that although work experience increases the disutility of further work the effect is overwhelmed by the positive effect of experience on wages leading to persistence in the employment patterns of these women in addition we find that an increase in young children and in husband s income substantially reduces participation while increased schooling has a powerful positive impact on participation this paper presents an estimable structural dynamic model of married women s labour force participation and fertility in which wages are stochastic and work experience or cumulative participation is endogeneous the model is structural in the sense that the parameters which are estimated are contained in the fundamental relationships governing behaviour namely the utility function and the constraints the model is contained in the class of models which describe the life cycle capital accumulation process with endogeneous labour supply such as weiss 1972 and heckman 1976 it is closest in spirit to that of weiss and gronau 1981 1 the basic feature of their model and ours is that labour market participation affects future wages which then affects future participation the investment return to current work will necessarily be taken into account in any forward looking optimizing model as weiss and gronau note estimates of labour supply models have ignored the inherent behavioural dynamics associated with a positive wageexperience profile there is no adequate empirical treatment of the human capital investment dimension of the labour force participation decision in the literature heckman and willis 1977 have studied a sequential discrete choice model of the labour force participation of married women in a reduced form framework their work

the econometrics of nonlinear budget sets traditional empirical analysis of consumer demand has usually made the assumption of linear budget sets that is the consumer is assumed to purchase any desired quantity at a constant price subject to a budget constraint the major exception to this framework is the analysis of demand when some goods are rationed 2 in the rationed case the price is constant up to a quantity limit in contrast to the rationed case here i consider the situation where the price varies with the amount of the good purchased empirical situations with nonconstant prices come readily to mind and of course they have received much recent attention from theorists since mirrlees 44 paper on optimal nonlinear taxation the following examples are meant to give a partial listing of cases when nonlinear budget sets occur i electricity prices many electric utilities engage in declining block pricing that is the marginal price of successive kwh s of electricity decrease at a given number of points determined by total demand thus the budget set is piecewise linear houthakker 36 was the first to propose an approach to this problem taylor 51 analyzes the problem at length and hausman kinnucin and mcfadden 31 use an instrumental variables estimator to provide consistent estimates of the demand function

top incomes in the long run of history a recent literature has constructed top income shares time series over the long run for more than twenty countries using income tax statistics top incomes represent a small share of the population but a very significant share of total income and total taxes paid hence aggregate economic growth per capita and gini inequality indexes are sensitive to excluding or including top incomes we discuss the estimation methods and issues that arise when constructing top income share series including income definition and comparability over time and across countries tax avoidance and tax evasion we provide a summary of the key empirical findings most countries experience a dramatic drop in top income shares in the first part of the twentieth century in general due to shocks to top capital incomes during the wars and depression shocks top income shares do not recover in the immediate postwar decades however over the last thirty years top income shares have increased substantially in english speaking countries and in india and china but not in continental european countries or japan this increase is due in part to an unprecedented surge in top wage incomes as a result wage income comprises a larger fraction of top incomes than in the past finally we discuss the theoretical and empirical models that have been proposed to account for the facts and the main questions that remain open

using notches to uncover optimization frictions and structural elasticities theory and evidence from pakistan we develop a framework for nonparametrically identifying optimization frictions and structural elasticities using notches discontinuities in the choice sets of agents introduced by tax and transfer policies notches create excess bunching on the low tax side and missing mass on the high tax side of a cutoff and they are often associated with a region of strictly dominated choice that would have zero mass in a frictionless world by combining excess bunching observed response attenuated by frictions with missing mass in the dominated region frictions it is possible to uncover the structural elasticity that would govern behavior in the absence of frictions and arguably capture long run behavior we apply our framework to tax notches in pakistan using rich administrative data while observed bunching is large and sharp optimization frictions are also very large as the majority of taxpayers in dominated ranges are unresponsive to tax incentives the combination of large observed bunching and large frictions implies that the frictionless behavioral response to notches is extremely large but the underlying structural elasticity driving this response is nevertheless modest this highlights the inefficiency of notches by creating extremely strong price distortions they induce large behavioral responses even when structural elasticities are small

estimating life cycle labor supply tax effects we present an econometrically tractable life cycle labor supply model for panel data including intertemporally progressive taxes on uncertai wage and nonwge incomes our two stage fixedeffects generalized method of moments approach first extimates intretemporal and then intertemporal preferences specification testing domonstrates the value of incorporating joint progressive taxation of labor and nonlabor incomes results for prime age men emphasize the roles played by hourly wage endogeneity worker specific effects the measure of the rate of pay and intemporal budget constaint nonseparability simulations indicate that recent tax reform while not self financing stimulated made labor supplied by about 3 percent and reduced deadweight loss about 16 percent

the specification and estimation of dynamic stochastic discrete choice models a survey our main goal is to quantify the returns to a career in the united states congress we specify a dynamic model of career decisions of a member of congress and estimate this model using a newly collected dataset given estimates of the structural model we

the effects of health wealth and wages on labour supply and retirement behaviour this paper estimates a life cycle model of labour supply retirement and savings behaviour in which future health status and wages are uncertain individuals face a fixed cost of work and cannot borrow against future labour pension or social security income the method of simulated moments is used to match the life cycle profiles of labour force participation hours worked and assets that are estimated from the data to those that are generated by the model the model establishes that the tax structure of the social security system and pensions are key determinants of the high observed job exit rates at ages 62 and 65 removing the tax wedge embedded in the social security earnings test for individuals aged 65 and older would delay job exit by almost one year by contrast social security benefit levels health and borrowing constraints are less important determinants of job exit at older ages for example reducing social security benefits by 20 would cause workers to delay exit from the labour force by only three months

adjustment costs firm responses and micro vs macro labor supply elasticities evidence from danish tax records we show that the effects of taxes on labor supply are shaped by interactions between adjustment costs for workers and hours constraints set by firms we develop a model in which firms post job offers characterized by an hours requirement and workers pay search costs to find jobs we present evidence supporting three predictions of this model by analyzing bunching at kinks using danish tax records first larger kinks generate larger taxable income elasticities second kinks that apply to a larger group of workers generate larger elasticities third the distribution of job offers is tailored to match workers aggregate tax preferences in equilibrium our results suggest that macro elasticities may be substantially larger than the estimates obtained using standard microeconometric methods

household choices in equilibrium this paper is an empirical investigation of equilibrium restrictions on household consumption and male labor supply it exploits a simple factor structure rationalized by two assumptions that household allocations are pareto optimal and that the labor market is competitive the paper estimates household preferences and tests how well this parsimonious factor structure represents panel data on married couples and time series data on asset returns most of the estimates are roughly comparable to those found in previous work no evidence against the simple factor representation is found and the intertemporal capital asset pricing model is not rejected copyright 1990 by the econometric society

measurement of government budget deficit and fiscal stance in a less developed economy the case of tanzania 1966 1984 abstract the use of the conventional government budget deficit as a measure of fiscal inclination and fiscal impact as has been the case in tanzania has been strongly criticized in the literature using alternative measures of the government budget deficit this paper indicates that contrary to the common view of consistent fiscal expansionism the government has pursued both expansionary and contractionary fiscal stances the paper notes that the government s contractionary fiscal stance in the 1970s was able to arrest tanzania s inflation and external imbalances since 1979 however the phenomenon has changed as the economy has experienced a severe foreign exchange crisis and quantity constraints in the goods sector accordingly the relevance of adopting the cyclically adjusted budget framework which may facilitate the coordination of government supply side responses with the need for financial discipline has been underlined however as the paper further demonstrates the choice of cyclical adjustment ratios and of potential gdp growth rate is important if either the unsustainability of the cyclically adjusted budget magnitudes or undue deflation are to be averted

intersectoral labor mobility and the growth of the service sector one of the most striking changes in the u s economy over the past 50 years has been the growth in the service sector between 1950 and 2000 service sector employment grew from 57 to 75 percent of total employment however over this time the real hourly wage in the service sector grew only slightly faster than in the goods sector in this paper we assess whether or not the essential constancy of the relative wage implies that individuals face small costs of switching sectors and we quantify the relative importance of labor supply and demand factors in the growth of the service sector we specify and estimate a two sector labor market equilibrium model that allows us to address these empirical issues in a unified framework our estimates imply that there are large mobility costs output in both sectors would have been double their current levels if these mobility costs had been zero in addition we find that demand side factors that is technological change and movements in product and capital prices were responsible for the growth of the service sector

labour supply in a two period model the effect of a nonlinear progressive income tax earlier studies of labour supply in a life cycle context have typically either neglected taxes completely or represented the income tax by a linear function the present paper studies how the qualitative conclusions of a traditional life cycle model of labour supply are changed when a nonlinear tax is introduced into the model it is shown that the comparative statics results and the characterization of the consumption and labour supply paths depend critically on whether capital and labour income are taxed jointly or separately and on the progressivity nonlinearity of the income tax few of the results valid for a linear income tax carry over to the nonlinear case

individual heterogeneity and interindustry wage differentials estimates of interindustry wage differentials are obtained using a fixed effects estimator on a long panel the national longitudinal survey of young men nls after controlling for observable worker characteristics 84 percent of the residual variance of log wages across industries is explained by individual fixedeffects only 16 percent of the residual variance is explained by industry dummies since no controls for specific job characteristics are used job characteristics that vary across industries could potentially explain this rather small residual across industry log wage variance that is not attributable to individual effects clearly then these data do not force us to resort to noncompetitive explanations of interindustry wage differentials such as efficiency wage theory furthermore efficiency wage theories predict that wages in efficiency wage paying or primary industries should be relatively rigid therefore industry wage differentials should widen in recessions however no such tendency is found in the data

profiles of fertility labour supply and wages of married women a complete life cycle model of all the major economic and demographic events in the postwar united states period the trends in fertility and female labour supply stand out as among the most dramatic fertility rates after their depression lows rose unexpectedly after world war ii far more than was anticipated as an adjustment to the war and continued to rise until the late 1950 s and early 1960 s when they again took an unexpected turn downward all the way to today s historical lows female labour force participation rates continuing their historical climb grew throughout the postwar period at an increasing pace by 4 percentage points during the 1950 s by 5 percentage points during the 1960 s and by 8 percentage points during the 1970 s these two trends are of course closely related for most married women have traditionally spent at least some minimal time out of the labour force while caring for their own children thus for example the slower growth rate of labour force participation rates in the 1950 s is probably connected with the higher fertility rates in that period in this paper a complete model of female labour supply and fertility choice is constructed and estimated the model is more complete than previous models in several respects first labour supply and fertility decisions are modelled as completely joint in the same sense as the consumption of two goods is joint second both are modelled as life cycle decisions that is as decisions regarding sequences of labour supply and fertility events rather than levels of the same hence the timing of both is important third the life cycle path of wage rates is made endogenous to the model given a wage function showing the effect of work experience on future wages the path of wages is determined automatically by the chosen path of labour supply which in turn is related to fertility decisions that require some period of non work econometrically the three profiles for labour supply fertility and wages are estimated with a full information maximum likelihood technique that solves several econometric problems such as the problem of heterogeneity of tastes the selectivity problem of missing wage rates for non workers and the problem of simultaneous equations bias the value of constructing a complete model is best seen by briefly reviewing past work in this area the modern literature in the area is based upon the work of becker

evaluating the german mini job reform using a natural experiment increasing work incentives for people with low income is a common topic in the policy debate across european countries the mini job reform in germany had a similar motivation we carry out an ex post evaluation to identify the short run effects of this reform our identification strategy uses an exogenous variation in the interview months in the socio economic panel study soep which allows us to distinguish groups that are affected by the reform from those who are not to account for seasonal effects we additionally use a difference in differences did strategy descriptives show that there is a post reform increase in the number of mini jobs however we show that this increase cannot be causally related to the reform since the short run effects are very limited only single men seem to react immediately and increase secondary job holding

the elasticity of taxable income in the presence of deduction possibilities several recent studies show that the elasticity of taxable income eti is not a sufficient statistic for the welfare costs of taxation due to factors such as tax base shifting this paper provides an additional argument demonstrating the non sufficiency of the eti namely tax deductions building on a theoretical framework which incorporates deductions in a standard optimal tax model we show that the eti is not sufficient for welfare analysis if i deductions generate externalities and if ii deductions are responsive to tax rate changes while the first condition should arguably hold true for the majority of tax deductions we provide an empirical examination of the second condition relying on rich german panel data from administrative tax records we exploit several tax reforms that were implemented in germany between 2001 and 2008 our main estimates indicate an overall eti between 0 54 and 0 68 and an elasticity of deductions with respect to the net of tax rate of about 0 9 these results suggest that the eti is not sufficient to calculate the welfare cost of taxation

nominal contracting theories of unemployment evidence from panel data this paper examines economywide and sector specific responses of real wages to nominal shocks using micro panel data from the national longitudinal survey of young men the observed response patterns provide no support for nominal contracting theories of unemployment which predict that nominal surprises should be negatively correlated with real wages in fact both inflation and money growth surprises are found to be essentially uncorrelated with real wages either a real business cycle model or a model with rigidities in commodity prices could be consistent with these results copyright 1993 by american economic association

marginal tax rates and tax favoured pension savings of the self employed evidence from sweden in recent years the study of how individuals respond to policies that aim at promoting pension savings has emerged as a vital area of economic research this paper adds to this body of literature by estimating the tax price elasticity of contributions to tax favoured pension savings accounts on a population of self employed individuals i exploit a unique total database over the swedish population that covers the years 19992005 using instrumental variables i obtain a tax price elasticity estimate of 0 51 and an income elasticity estimate of 0 13 whereas ordinary least squares ols produces estimates that conflict with consumer theory

corrigendum on a life cycle model of female labour supply in the empirical work in our article on the intertemporal substitution of leisure time for married women heckman and macurdy 1980 we inadvertently constrained the estimated intertemporal substitution elasticity to be too high since this parameter plays a prominent role in discussions of equilibrium models of the business cycle and since our empirical work has been cited in discussions on this topic e g hall 1980 we would like to present a corrected set of empirical results for our model the period t utility function adopted in this note is in the notation of our original paper equation 15

adjustment cost and incentives to work evidence from a disability insurance program abstract how important is adjustment cost for individuals who face a change in work incentives induced by a policy change i provide the first estimate of adjustment cost in the context of a disability insurance di program by exploiting a policy change that increased work incentives by increasing the exemption threshold i use bunching at the thresholds to estimate adjustment cost and earnings elasticity the estimates of adjustment cost are quite sizeable and heterogeneous the estimates of earnings elasticity from both static and dynamic models are larger than the elasticity estimated with no adjustment cost suggesting that adjustment cost attenuates the responses to work incentives policies designed to increase labor supply will work if the work incentives are large enough to offset the adjustment cost accounting for adjustment cost then might explain the disparate findings on the effects of an increase in work incentives on the labor supply of beneficiaries of di programs
