is there a causal effect of working part time on current and future wages in this paper i study the causal effects of part time work on current and future wages to estimate these effects i use a random effects model with a wage equation capturing the employment history and a dynamic multinomial probit component for the choice of employment status exclusion restrictions from the institutional context are exploited to support identification the results suggest that working part time with few hours has a large causal effect on current wages but more extensive part time work does not reduce current wages however both types of part time work lead to negative long term wage effects

on the determinants of employer demand for part time workers this paper uses a survey of private establishments to examine the determinants of the firm s relative demand for partand full time workers the elasticity of substitution of part time for full time workers is about 1 5 considerably lower than previous estimates with aggregate data the results indicate that the quasi fixed labor costs have a negative impact on the proportion of part timers in a firm s work force

the effect of food stamps on labor supply a bivariate selection model abstract although there is a large literature on the effects of u s transfer programs on labor supply this is the first such study of the food stamp program we model the nonlinearity and nonconvexity of the budget constraint and use maximum likelihood methods to estimate hours of work functions for female heads of household the largest recipient group in the program we also model the joint response to afdc and food stamps and we account for the existence of a significant number of eligible households who do not participate in the programs a three equation bivariate selection model is estimated on a sample of eligible households with maximum likelihood

schooling fertility and the labour market experience of married women a model of career path choice is constructed for a sample of women taken from the 1991 us national household education survey this allows for simultaneity and selection effects in the relationship between regime choice and earning it is established that inter alia expected earnings have a significant impact on the career path and the hours of work chosen by american women the role played by formal schooling and by childrearing in the determination of carrier path is highlighted and implications are discussed

tourists spending and adherence to shopping plans the case of the christmas market in merano italy abstract the present paper investigates the determinants of tourists expenditure by categorizing tourists based on their mental budgets individuals can be divided into three categories based on the difference between their mental budget and actual expenditure underspenders on budget spenders and overspenders estimation of the empirical model is performed based on data collected through a survey of visitors to the christmas market in merano italy during advent in 2011 the estimation is performed with the heckman estimator ordered probit selection rule and linear regression we find that the spending patterns of visitors belonging to the three identified categories differ significantly analyzing visitors expenditure based on the proposed categorization allows us to identify category specific factors and develop management strategies for each category the managerial and theoretical implications of the results are discussed

a joint dynamic model of fertility and work of married women this article estimates a dynamic model of fertility and labor supply of married women drawn from the national longitudinal survey of young women 1968 91 it distinguishes part time and full time employment sectors which differ by pecuniary and nonpecuniary returns and transferability of human capital the model with unobserved heterogeneity in earning ability and preferences for children fits the data and produces reasonable forecasts of labor force participation in decisions the estimates unpack important features of the persistence in labor market decisions intertemporal substitution of leisure over the life cycle and the effect of work interruptions due to childbirth on lifetime utility

nominal price rigidity money supply endogeneity and business cycles abstract this paper investigates the ability of nominal price rigidity to explain the co movement of inflation with the cyclical component of output observed in the post war u s data a dynamic general equilibrium model is constructed with the introduction of monopolistic competition and nominal price rigidity in a standard real business cycle model allowing for an endogenous money supply rule it is then demonstrated that sticky price models can explain the observed associations between movements in inflation and output much better than flexible price models this result depends little on whether money supply is assumed to be endogenous or not

the estimation of a joint wage hours labor supply model in this paper the standard cross sectional static model of labor supply is modified to make the wage endogenous and a joint wage hours model is estimated the econometric technique addresses the non linearity of the budget constraint by approximating the constraint by a series of discrete points the results show that the budget constraint is indeed nonlinear that hours affect the wage quadratically that true wage elasticities are lower as a result and that the model fits the hours distribution much better than the standard tobit model

comparing new keynesian models of the business cycle a bayesian approach abstract the baseline new keynesian model cannot replicate the observed persistence in inflation output and real wages for sensible parameter values as a result several extensions have been suggested to improve its fit to the data we use a bayesian approach to estimate and compare the baseline sticky price model of calvo s 1983 staggered prices in a utility maximizing framework journal of monetary economics 12 383 398 and three extensions our empirical results are as follows first we find that adding price indexation improves the fit of calvo s 1983 staggered prices in a utility maximizing framework journal of monetary economics 12 383 398 model second models with both staggered price and wage setting dominate models with only price rigidities third introducing wage indexation does not significantly improve the fit fourth all model estimates suggest a high degree of price stickiness fifth the estimates of labor supply elasticity are higher in models with both staggered price and wage contracts finally the estimated inflation parameters of the taylor rule are stable across models

child support reform and the labor supply of lone mothers in the united kingdom the reform of child support arrangements including their treatment by the welfare system has been on the policy agenda in a number of countries in recent years this paper simulates the impact of a reform that recently has been implemented in the united kingdom the analysis is based on estimates of a model of discrete choice labor supply for a sample of u k lone mothers we suggest that reform will induce a major reduction in welfare expenditures on lone mothers and a significant rise in their labor force participation due to greater work incentives associated with the changes

the labour supply unemployment and participation of lone mothers in in work transfer programmes in work transfer schemes have recently been suggested as a device for encouraging labour force participation and reducing the severity of the disincentives associated with out of work income support schemes here we estimate a discrete choice labour supply model which allows for endogenous in work welfare programme participation we also allow for involuntary unemployment so as to distinguish between programme non participation and an inability to obtain work and thereby generate an eligibility to the programme

does labor s share drive inflation a number of researchers have recently argued that the new keynesian phillips curve matches the empirical behavior of inflation well when the labor income share is used as a driving variable but fits poorly when deterministically detrended output is used the theoretical motivation for these results rests on the idea that the output gap the deviation between actual and potential output is better captured by the labor income share in turn implying that central banks should raise interest rates in response to increases in this variable we show that the empirical evidence generally suggests that the labor share version of the new keynesian phillips curve is a very poor model of price inflation we conclude that there is little reason to view the labor income share as a good measure of the output gap or as an appropriate variable for incorporation in a monetary policy rule

a quantitative comparison of sticky price and sticky information models of price setting i estimate sticky price and sticky information models of price setting for the united states via maximum likelihood techniques reaching several conclusions first the sticky price model fits best and captures inflation dynamics as well as reduced form equations once hybrid behavior is allowed second the importance of hybrid behavior in sticky price models is potentially consistent with a role for some information imperfections such as sticky information as a complement to nominal price rigidities finally the favorable results herein for the hybrid sticky price model when evaluated by statistics that summarize the relative fit of different models is consistent with the existing literature that is both supportive and dismissive of such models as this literature has largely ignored fit in evaluating such models many previous studies have focused on ancillary issues such as the standard errors associated with certain parameters or granger causality tests that may not provide much information about sticky price models

the effects of progressive taxation on labor supply when hours and wages are jointly determined this paper extends a standard intertemporal labor supply model to account for progressive taxation as well as the joint determination of hourly wages and hours worked we show that these two factors can have implications for both estimating labor supply elasticities as well as for using these elasticities in tax analysis failure to account for wage hours ties and progressive taxation may cause the hours response to marginal tax rate changes to be understated by 5 to 30 percent for men

gender discrimination in the british labour market a reassessment survey wes the wes is the first british survey to collect detailed work histories and earnings data for a nationally representative sample of british women therefore for the first time estimates of discrimination based on real work experience data are presented a number of the earlier studies use data from the general household survey which does not collect actual work experience data they have been forced to use potential work experience or imputed experience in their wage equations this paper compares estimates based on potential or imputed experience with those based on actual experience using wes data our analysis finds that estimates of the parameters of a women s earnings function and a summary measure of gender discrimination using a measure of imputed experience differ little from those based on actual experience indeed our estimates of gender discrimination are very robust to estimation method and only slightly higher than miller s i987 estimate for i980 these estimates indicate that the oft quoted and influential study by zabalza and arrufat i 982 i 985 which pioneered the use of imputed experience severely underestimated the level of gender discrimination and exaggerated the impact

technology shocks in the new keynesian model in the new keynesian model preference cost push and monetary shocks all compete with the real business cycle model s technology shock in driving aggregate fluctuations a version of this model estimated via maximum likelihood points to these other shocks as being more important for explaining the behavior of output inflation and interest rates in the postwar u s data these results weaken the links between the current generation of new keynesian models and the real business cycle models from which they were originally derived they also suggest that federal reserve officials have often faced difficult trade offs in conducting monetary policy

the demarcation of land and the role of coordinating property institutions we use a natural experiment in nineteenth century ohio to analyze the economic effects of two dominant land demarcation regimes metes and bounds mb and the rectangular system rs mb is decentralized with plot shapes alignment and sizes defined individually rs is a centralized grid of uniform square plots that does not vary with topography we find large initial net benefits in land values from the rs and also that these effects persist into the twenty first century these findings reveal the importance of transaction costs and networks in affecting property rights land values markets and economic growth

wage offers and full time and part time employment by british women strong evidence in support of the hypothesis that women receive lower wage offers in part time jobs than in full time jobs is provided by estimation of wage offer functions for british women which control for self selection into these two types of jobs analysis of married women s employment decisions indicates that the difference in a woman s expected wage offers between full time and part time employment is an important determinant of whether she works full time while husband s income mainly affects the decision of whether to work in addition it appears that women who work despite having observed characteristics that discourage employment are much more likely to work part time

working part time by choice or by constraint the selection of workers into part time jobs and the wages they earn are analysed using the 1989 labour market activity survey we focus on the distinction between voluntary and involuntary part time workers since involuntary part time workers earn substantially lower wages than other workers we find that the selection of individuals into involuntary part time work is more closely tied to job characteristics than personal or human capital characteristics the lower wage earned by involuntary part time workers is largely due to differences in returns and selection effects rather than differences in endowments

children and female labour supply behaviour using the generalized residual method this paper investigates the assumption that children are exogenous in the labour supply equations of married women via alternative regression specifications for the children variables the empirical results of this paper suggest that children are endogenous to the participation decision and likely to be exogenous to the hours of work decision for married women children under age six have a dramatic negative impact on the labour force participation of married women these findings support the implication of the literature relating fixed costs of employment including child care costs to female labour supply

the gender salary gap in british academia this paper considers salary determination and the gender salary gap in the academic labour market utilizing a particularly detailed data set of academics from five old established universities results reveal an aggregate gender salary differential for academic staff of 15 most of this differential can however be explained by our model evidence suggests a limited opportunity for female academics to combine career and family despite the flexibility of an academic job and emphasizes the importance of mobility to the male career publication record is found to be an important determinant of salary

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

partial adjustment and staggered price setting this paper compares taylor style staggered price setting to partial adjustment of prices or calvo staggering in a small optimizing is lm model in contrast to the overwhelming perception in the literature the models are not similar for most parameterizations in particular the dynamic response of the economy to shocks is quite different in the two models and the welfare cost of price rigidity is eight or more times larger in the calvo model than in the taylor model for typical calibrations suggestions for calibrations under which the models are more similar are also presented

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

part time work wages and productivity evidence from belgian matched panel data the authors use matched employer employee panel data on belgian private sector firms to estimate the relationship between wage productivity differentials and the firm s labor composition in terms of part time work and gender findings suggest that the groups of women and part timers generate employer rents but also that the origin of these rents differs relatively lower wages for women relatively higher productivity for part timers interactions between gender and part time work suggest that the positive productivity effect is driven by male part timers working more than 25 hours whereas the share of female part timers is associated with wage penalties the authors conclude that men and women differ with respect to motives for reducing working hours and the types of part time jobs available to them women often have to accommodate domestic constraints by downgrading to more flexible jobs whereas male part time work is frequently related to training and collectively negotiated reductions in hours that

sticky price models and the natural rate hypothesis abstract a major criticism of standard specifications of price adjustment in models for monetary policy analysis is that they violate the natural rate hypothesis by allowing output to differ from potential in steady state in this paper we estimate a dynamic optimizing business cycle model whose price setting behavior satisfies the natural rate hypothesis the price adjustment specifications we consider are the sticky information specification of mankiw and reis sticky information versus sticky prices a proposal to replace the new keynesian phillips curve quarterly journal of economics 117 1295 1328 and the indexed contracts of christiano et al nominal rigidities and the dynamic effects of a shock to monetary policy journal of political economy 113 1 45 our empirical estimates of the real side of the economy are similar whichever price adjustment specification is chosen consequently the alternative model specifications deliver similar estimates of the u s output gap series but the empirical behavior of the gap series differs substantially from standard gap estimates

interindustry part time and full time wage differentials regional and national analysis this paper provides more evidence that the wage differential is far smaller than is suggested by simple comparison of gross wages of full time and part time workers it is noted that to obtain a more reasonable measure of the full time and part time wage differential it is necessary to adjust for differences in workers characteristics labour market conditions and sample selection it is found that in general full time and part time workers exhibit different personal characteristics in particular full time workers possess more human capital and experience than part timers also labour market conditions such as unions and pension plans favour full timers these differences may partly account for the wage disparity between full time and part time workers it was noted that the nonrandomness of the workers into full time and part time jobs influences the wage determination of both full time and part time workers the results indicate that the adjustment of the wage equations to reflect the above menti

the effect of part time work on wages evidence from the social security rules this article identifies the part time wage effect using hours variation caused by the social security rules we show that work hours and wages drop sharply at ages 62 and 65 we argue that the hours decline causes the wage decline resulting in a 25 wage penalty for men who cut their work week from 40 to 20 hours however we find little evidence for such an effect among women we also show that models that fail to account for the joint determination of hours and wages will understate the labor supply response to a tax change by about 26

part time wage penalties for women in prime age a matter of selection or segregation evidence from four european countries using the european union statistics on income and living conditions data for the year 2009 the authors evaluate how vertical and horizontal job segregation explains the differential between full t

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

pricing models a bayesian dsge approach for the u s economy this paper compares and estimates three pricing mechanisms in the context of a small dsge model of the u s economy we interpret our results as favoring the pricing mechanism presented in wolman 1999 wolman model over the new keynesian model with indexation gali and gertler 1999 smets and wouters 2004a and the sticky information model of mankiw and reis 2002 the key factor that explains the performance of the wolman model is that the data reject the key assumption of the new keynesian model that the firm s probability of price change is constant over time and independent of the contract s vintage our results also show that incorporating indexation in the new keynesian model represents a poor expedient in matching the autocorrelation function of the inflation process over the last 20 years

analysis of part time pay in canada this paper analyses the difference between part time and full time wages in canada using the 1981 survey of work history since part time and full time workers are distinguished by hours worked and since hours worked and wages are interdependent selectivity bias occurs if ordinary least squares regression is used a modification of heckman s procedure to account for the fact that part time hours are doubly truncated is used to correct this problem the results indicate that adjusting for differences in characteristics the wage differential between part time and full time workers is 10 per cent or one third the unadjusted differential results vary somewhat by sex and marital status analyse de la remuneration du travail d temps partiel au canada ce memoire analyse les differences entre les salaires pour le travail a temps plein et a temps partiel au canada a partir des resultats de l enquete sur l activite en 1981 puisque les travailleurs a temps plein et a temps partiel sont definis par le nombre d heures de travail et puisque le nombre d heures de travail et les niveaux de salaire sont interdependants il y a biais de selectivite quand on utilise la methode des moindres carres ordinaires dans l analyse de regression l auteur utilise une modification de la technique de heckman pour tenir compte du fait que le nombre d heures de travail a temps partiel est doublement tronque pour corriger le probleme les resultats montrent que apres avoir tenu compte des differences dans les caracteristiques des personnes on observe un differentiel de niveau de salaire de 10 pourcent entre les travailleurs a temps plein et a temps partiel soit le tiers du differentiel brut avant les ajustements pour tenir compte de caracteristiques differentes ces resultats varient quelque peu selon le sexe et selon la situation familiale the trend towards part time employment has generally escaped the attention and scrutiny of economists part time employment in canada grew at an annual rate of 4 1 per cent between january 1972 and january 1984 compared 1 one exception is nakamura and nakamura 1983 who examine related labour supply issues for married females canadian journal of economics revue canadienne d economique xix no 4 november novembre 1986 printed in canada imprim6 au canada 0008 4085 86 798 807 1 50 0 canadian economics association this content downloaded from 207 46 13 159 on sat 22 oct 2016 04 29 38 utc all use subject to http about jstor org terms analysis of part time pay in canada 799 with a growth rate of only 2 4 per cent for full time employment as a result 15 4 per cent of jobs were part time as of january 1984 compared with 13 per cent in january 1972 2 the growth of part time employment raises a number of issues in particular labour canada 1983 argues that the hourly wage differential between full time and part time workers reached 26 3 per cent in 1981 it is not clear however that this gross wage differential between full time and part time workers is a useful figure a number of accepted measurable characteristics that determine wage differentials among workers may confound this comparison unless full time and part time workers have identical characteristics it would therefore be useful from a policy standpoint to eliminate these effects to identify part time effects and the gravity of the part time pay problem per se this paper analyses the differences between part time and full time wages to try to distinguish part time effects whatever the source from other established bases for differentials in the first section a standard model for wage comparison among workers is considered the source of selectivity bias is identified and a consistent estimation technique is described the second section uses this technique to analyse the differences in part time and full time wages using microdata from the 1981 survey of work history used by labour canada 1983 the third section summarizes the results and provides suggestions for further research a model for wage comparison with selectivity bias consider a standard model used extensively for union and non union wage comparisons lee 1978 duncan and leigh 1980 robinson and tomes 1984 simpson 1985 let wf be a vector of observations on the natural logarithm of hourly wages paid to full time workers and let x be a matrix of observations on measurable worker characteristics commonly used in such models namely educational attainment age sex union status public vs private sector status and region let wp and x be the corresponding observations for part time workers let h be the maximum hours of work permitted for classification as a part time worker then we specify wf xff3f if if h h 1

optimal price setting and inflation inertia in a rational expectations model abstract this paper presents and estimates a new keynesian monetary model for the us economy it proposes possible solutions to two problems in this model class the lack of inflation inertia and persistence in versions of these models that insist on rigorous microfoundations and rational expectations and the small contribution of technology shocks to business cycles price setting takes the form of optimal two part pricing policies formulated under conditions of upward sloping firm specific marginal cost curves furthermore this form of price setting applies not only to prices and wages but also to user costs of capital in this setting past inflation becomes a key determinant of current inflation even though price setting is entirely forward looking technology is modeled as a random walk with technology growth shocks that follow a highly persistent process the model is estimated by bayesian methods and performs significantly better than a bayesian var it generates inertial and persistent inflation and technology shocks account for a large share of business cycle variation

sticky price and sticky information price setting models what is the difference using a partial equilibrium framework mankiw and reis 2002 show that a sticky information model can generate a lagged and gradual inflation response after a monetary policy shock whereas a sticky price model cannot our paper demonstrates that that finding is sensitive to their model s parameterization to determine a plausible parameterization we specify a general equilibrium model with sticky information in that model we find that inflation peaks only one period after a monetary disturbance a sensitivity analysis of our results reveals that the inflation peak is delayed by including real rigidities when the monetary policy instrument is money growth whereas inflation peaks immediately when the policy instrument is the nominal interest rate

family structure home time demands and the employment patterns of japanese married women a recent 1990 national survey is used in an econometric analysis of japanese women s hourly pay and employment patterns it confirms many results from western industrial countries but also indicates the important influence of japan s unique family structure the persistence of multigenerational households on married women s employment patterns younger married women are more likely to take paid employment in such households particularly on a full time basis than in nuclear family households this appears to reflect in part the child care role played by the woman s parents or parents in law
