The determinants of female labour supply in Hungary

The aim of this paper is to closely examine the effect on a married woman's labour supply decision of non-labour income and of her own wage rate in a transition economy. The paper first shows that labour force participation rates for Hungarian females, though decreasing, were still extremely high and comparable to male economic activity in western countries. It then estimates labour supply parameters using a model that controls for sample selection issues associated with the labour supply of married women. Wage elasticity is estimated to be high and positive (1.81) while the income effect is consistent with leisure being a normal good. No sample selection bias is found.     

Estimating labour supply responses and welfare participation: Using a natural experiment to validate a structural labour supply model

We estimate an economic model of labour supply and welfare participation using data on single men from Quebec drawn from the 1986 Canadian Census. Detailed budget sets for each work‐welfare combination—accounting for income taxes, tax credits and welfare benefit rules—are derived using a micro‐simulation model. We show that predicted reactions to a welfare reform that took place in 1989 replicate actual changes in labour supply and welfare participation. We also illustrate the advantage of having estimated a structural model by showing how labour supply and welfare participation change when income taxes and benefit levels change.     

A panel study of labour supply and taxes in Denmark

The labour supply of Danish married couples is estimated on a longitudinal sample of about 3000 Danish couples observed over the period 1980–86. The influence of the progressive tax system and the effect of the unemployment insurance system are evaluated. The definition of unemployment in labour-supply functions is discussed, and two separate models are estimated where unemployment is considered either completely voluntary or completely involuntary. The wage elasticity and the supply effects of tax reduction are estimated to be positive, but numerically small for both men and women.     

On selecting a measure of labour activity: evidence from registered nurses, 1981 and 1989

The purpose of this paper is to demonstrate the effects of the selection of measures of labour activity on the conclusions that are derived from the analysis of individual labour supply. The results of the analysis using three commonly specified single measures (Annual Hours Worked, Hours Worked per Week, and Weeks Worked per Year) as the dependent variable in TOBIT equations are compared with those obtained using a PROBIT-2SLS in which the individual labour supply is measured by Hours Worked per Week and Weeks Worked per Year. The RHS variables are those that are used in earlier individual labour supply studies and are the same in all of the models analysed. Among the findings are (1) wage rate effects that are quite strong in single equation models and disappear when a multi-equation approach is used, (2) the effects of children on labour supply is more complex than in indicated in single equation results and (3) duration dependence is much stronger than indicated results using a single measure of individual labour supply. These results suggest that using a single measure of labour supply will lead to inappropriate conclusions as to the effects of such variables as wage rates, number and ages of children, spouse's employment state, and income from other sources on individual labour supply.     

Do Austrian men and women become more equal? At least in terms of labour supply!

We study the development of wage elasticity of labour supply for Austrian men and women over time using comparable and representative survey data for the 1980s and 1990s. The elasticity of men is relatively low and constant over time, similar to the behaviour of single women. Most remarkable is the almost continuous reduction in the labour supply reactions of married women: while their elasticity was still several times larger at the beginning of the 1980s, they approached rapidly the much less elastic behaviour of men. These developments are important for the analysis of deadweight losses of taxation as well as the effects of tax reforms and wage subsidy programs.     

Does labour supply respond to a flat tax?

We exploit the exogenous change in marginal tax rates created by the Russian flat tax reform of 2001 to identify the effect of taxes on the labour supply of men and women. We apply a weighted difference‐in‐difference regression approach and instrumental variables to estimate labour supply functions using a panel dataset. The mean regression results indicate that the tax reform led to a statistically significant increase in hours of work for men but had no effect on work hours for women. However, we find a positive response to tax changes in both tails of the female work hour distribution. We also find that the reform increased the probability of finding a job among both men and women. Despite significant variation in individual responses, the aggregate labour supply elasticities are trivial. This suggests that reform‐induced changes in labour supply are an unlikely explanation for the amplified personal income tax revenues that followed the reform.     

Economic status of households and labour supply to market and non-market activities mdash; some results from a poor rural economy

Assuming a given underlying utility structure for all households, we have demonstrated that the differential labour supply behaviour among household categories results owing to the different sets of constraints they face depending on their economic status and asset ownership. Using the criteria implied by the theoretical model four household gorups are defined. The labour supply functions estimated for these four groups support the theoretical result of significantly different supply behaviour. The empirical exercise, as expected, indicates that the labour supply decision of the subsistence group is guided by their need to achieve the minimum level of consumption while the middle-income households, who do not have enough non-labour income to meet their minimum subsistence need, tend to work longer hours in market activities than the workers from high-income households. However, market labour supply by high-income households is found to be relatively more sensitive to changes in the wage rate. The behaviour of the household groups differ so significantly that if an aggregate model is estimated ignoring inter-household differences, the predicted hours will grossly over-estimate labour supply to market activities.     

Wages,work, and unemployment

This paper provides new evidence on unemployment durations for individuals in Great Britain using a three state Markov framework in a competing risk setting and a nationally representative data set. The analysis is based on the premise that an individual's movements between labour market states can be represented by a Markov process. The modelling procedure combines the dynamic properties of the search approach to unemployment while using the labour supply decision at each moment in time in response to the expected wage to include participation decisions. Using this framework, we are able to determine the effect of individual characteristics, including the expected wage, on labour market behaviour. The model is estimated separately for men and women, and for young and mature workers, to investigate whether labour market behaviour differs for these groups. The validity of the Markov assumptions are tested using different model specifications, and changes in the model over calendar time are also presented.     

Taxes,female labour supply and household income: differences between the Netherlands and the Federal Republic of Germany

The article investigates the effect of taxes and social premiums on female labour supply and household income. A comparison is made between labour supply and household income between the Netherlands and the Federal Republic of Germany in 1992. A discrete choice model for labour supply is used in which taxes and social premiums are implicitly incorporated. As male labour supply is highly inelastic an individual, male chauvinist model is used. The estimated models are used to simulate the effect of the differences in the tax and social premium system on the differences in labour supply and income between both countries. The results indicate that labour force participation is higher the more individualized the system. The German system leads to a lower tax burden compared to the Dutch system. It is concluded that differences in the tax and social premium system between both countries have hardly any influence on the differences in the inequality of net household labour income. There is evidence that the German system leads to a slightly more unequal distribution of household income. It is also concluded that although the tax and social premium system does influence labour supply and income, it can be doubted whether these effects are substantial.     

The Cost of Public Funds in Australia*

A model of labour supply is used to calculate Australia's marginal cost of public funds, which is the appropriate cut-off benefit/ cost ratio for an additional public project. The labour supply model incorporates effective average and marginal tax rates faced by the representative household in each gross income decile. These rates are estimated from the ABS 1988–89 Household Expenditure Survey. A simulation analysis is performed to calculate the effect on labour supply of a 1 per cent increase in marginal tax rates. The estimated changes in tax revenues and deadweight loss in each decile are used to estimate the marginal cost of public funds.     

Determinants of Child Labour in Indian States: Some Empirical Explorations (19612–1991)

This paper attempts to examine the phenomenon of child labour in India by conducting a preliminary search for the factors which affect demand and supply of child labour. The incidence of child labour is firstly examined with respect to the socio economie characteristics including dernographic, educational and economie poverty variables. Factor analysis is then conducted to identify patterns of these variables with the incidence of child labour for Indian states using Census data. These possible relationships are formally modelled in an overlapping generations framework which derives two postulated models. The models are estimated using Kmenta’s pooled method which combines variations due to time and state specific factors. These results clearly indicate the presence of vicious and virtuous spirals consisting of the above factors for different states. The supply factors appear to dominate and their roles require further indepth examination

     

Multi-family households in a labour supply model: a calibration method with application to Poland

Models of cooperative and noncooperative behaviour opened the household ‘black box’ and allowed for individual treatment of partners in couples. However, labour supply literature has so far largely ignored a broader issue – the distinction of single versus multi-family (‘complex’) households. We propose a method to account for multi-family household structure by borrowing from recent applications of the collective model to identify the degree of sharing. We assume that each household is characterized by a between-family sharing parameter, which is calibrated on estimated preferences, observed labour market status and other characteristics. We apply the method to Polish labour market data.     

Analysis of the 1980 Sydney Survey of Work Patterns of Married Women: Further Results*

Using cross-section data from the 1980 Sydney survey of the work patterns of married women, this paper contributes to the very scarce Australian stock of disaggregate econometric studies of the labour market activities of married women. Labour force participation, hours of work and wage functions (reservation wage as well as market wage) are estimated in a second-generation static labour supply framework. Unique features of the study include the availability of direct data on previous market experience, a formulation of the impact of children on the participation decision which permits testing for the presence of economies of scale in child-minding activities, estimation of the reservation wage function, and a data base which permits a clear distinction between earnings and other forms of income.     

A Cross-Section Analysis of the Labour Force Participation of Married Women in Australia

'In a time when whales and seals are classified as endangered species, babies also seem to be an endangered species ˙˙˙ with so many mothers in the workforce our population growth has dropped below zero and I think the Federal government should counter that trend˙˙˙˙ Babies born in Australia are our best new Australians.' (Senator Florence Bjelke-Petersen in a speech to the Women's Action Alliance, reported in the Canberra Times, 3 June 1981 .)
The paper examines the labour supply of married women in Australia using data from the 1974 Census of Population and Housing. A number of approaches to modeling are employed. In the first instance OLS equations are estimated. These estimates are compared with instrumental variable estimates endogenizing wage rates. and with estimates from a three-equation system endogenizing fertility as well as wages. The evidence suggests that many of the factors proposed by modern theory do exercise significant influences in anticipated directions on the labour supply of married women in Australia.     

The impact of taxes on female labour supply

There is little agreement in economics on the factors influencing labour supply and hence on the impact of taxes. Within the marginal model, real wages and incomes are directing people's labour market behaviour independent of time and space, whereas the human resources approach takes account of the social environment and past behaviour. Even if strong assumptions are made, the neoclassical theory cannot predict the outcome of a wage increase. The labour supply response depends on the relative strengths of the substitution and the income effect. Since nonparticipation in the labour market is explained by a reservation wage being higher than the market wage, this is the only situation in which neoclassical theory would predict a rise in labour force participation with a wage increase. This case occured in a ‘natural experiment’ in Sweden. The Swedish tax system changed in 1971 from joint to separate taxation of spouses resulting in a substantial increase in the net wage of married women. This article investigates the impact of the change in the Swedish tax system on female labour force participation, concluding that it cannot explain the substantial rise in the participation rates of Swedish women. This is a significant result, questioning standard neoclassical theory and supporting the more institutional views of human labour market behaviour. That is that time and space as well as the social environment are important when analyzing labour supply. This will have consequences for international comparisons. Only factors which explain developments within one country might be relevant for explaining international differences, e.g. in labour force participation.     

Family labour supply: some empirical results from agriculture

The family is often taken as the decision-making unit in utility maximizing theories of labour supply. At a simple level, the family is composed of two elements, dependents and workers. This paper seeks to quantify the influence of these two elements on family labour supply in agriculture. Family farms are particularly suited to such analysis since institutional rigidities, like the fixed working week, are absent. Econometric methods are used on data from farms in the north-west of england for the year 1976/7. The cross-sectional study uses single equation methods. The results show that only family composition determines the labour supply of the farm family: they can then be used to quantify the effects of individual groups of dependents and workers on family labour supply.     

THE GENDER PAY GAP UNDER DUOPSONY: JOAN ROBINSON MEETS HAROLD HOTELLING

This paper presents an alternative explanation of the gender pay gap resting on a simple Hotelling-style duopsony model of the labour market. Since there are only two employers, equally productive women and men have to commute and face travel cost to do so. We assume that some women have higher travel cost, e.g., due to more domestic responsibilities. Employers exploit that women on average are less inclined to commute and offer lower wages to all women. Since women's firm-level labour supply is for this reason less wage-elastic, this model is in line with Robinson's explanation of wage discrimination.     

Earnings,social security legislation and retirement decisions: the Austrian experience

This paper analyses the labour supply behaviour of elderly males in Austria and asks how far it is determined by the characteristics of the Austrian Social Security System. This is of particular interest because old age insurance in Austria is dominated by the public pension plan, so that private pension plans are of minor importance. I argue that from a theoretical point of view the actuarial unfairness of the insurance plan creates a strong incentive to withdraw from the labour force at the minimum retirement age. Secondly, the rising earnings replacement ratio might be responsible for the decreasing average retirement age. These hypotheses are tested empirically. A pooled time-series cross-sections labour force participation model is estimated for single birth year cohorts of elderly males. I find strong evidence for the proposition, that the age-participation pattern might be determined by the incentives created by social security and that the decrease in labour force participation rates over time may be due to the rising earnings replacement ratio. Remaining differences in labour force participation of elderly males may be attributable to cohort population size and to a long run trend.     

Collective Labour Supply: Heterogeneity and Non-Participation

We present identification and estimation results for the "collective" model of labour supply in which there are discrete choices, censoring of hours, and non-participation in employment. We derive the collective restrictions on labour supply functions and contrast them with restrictions implied by the usual "unitary" framework. Using the large changes in the wage structure between men and women in the U.K. over the last two decades, we estimate a collective labour supply model for married couples without children. The estimates of the sharing rule show that male wages and employment have a strong influence on bargaining power within couples.     

Housing Subsidies and Work Incentives in Great Britain

The relationship between housing costs, wages and transfer programmes is complex yet helps determine the incentive to work for individuals in low income or high housing cost households. We estimate a static discrete choice labour supply model that allows for housing benefit programme participation, using samples of married women and unmarried women drawn from Great Britain Family Resources Surveys 1994/5–97/8. We find women are quite responsive to labour supply incentives and that housing benefit income has similar incentive effects to earned income which suggests any 'stigma' is small. Our analysis is complemented by simulating housing benefit and direct rent subsidy reforms.
