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.     

Household labour supply in Britain and Denmark: some interpretations using a model of Pareto Optimal behaviour

This paper analyses the labour supply behaviour of households in Denmark and Britain. It employs models in which the preferences of individuals within the household are explicitly represented. The households are then assumed to decide on their labour supply in a Pareto Optimal fashion. Describing the structure of the household decision in this way allows preliminary results to be obtained on the internal weighting of utilities within the household.     

Gender roles,labour market participation and household income position

In empirical research on labour supply behaviour, variables like age, education or the household's financial situation as well as economic and demographic characteristics, social attitudes and gender role schemes are believed to influence the annual working hours. This paper starts from the assumption that these determinants work differently according to the poverty level of the household in which the individual lives. Using data from the German Socio-Economic Panel (GSOEP), the paper empirically tests this hypothesis for women and men living in households with a disposable income above the poverty line and of those living in poor households. The results of multiple regression analysis show traditional gender role patterns in labour supply decisions, but only for persons in households with an income above the poverty line.     

The Labor Market as a Smoothing Device: Labor Supply Responses to Crop Loss

The paper studies the way in which labor supply responses enable households to smooth consumption in the face of crop loss. The 1993 Indonesian Family Life Survey is unusual because it contains self-reported information on crop loss and on household responses to crop loss. Of those households that report a crop loss, 41.6% also report that they responded by taking an extra job. Using these self-reported measures, the authors find evidence which suggests that the income associated with this shock-induced labor supply is important in allowing the household to avoid reducing consumption expenditure. Household members, however, do not seem to increase their total hours of work. They appear to just reallocate their time from household farming to other labor market activities.     

TECHNOLOGICAL CHANGE, INEQUALITY AND WORK SHARING

The effects of technological change on wage inequality are usually studied under the assumption of exogenous supplies of skilled and unskilled workers. Moreover, in these studies there is no distinction between the stock (number of workers) and the flow (hours of work) dimension of labour services. In the present paper, we construct a model in which hours of work and technological change affect both the (relative) demand and supply of unskilled workers. The labour supply of unskilled workers (numbers of persons) is derived from a model of household labour supply in which households differ regarding the disutility suffered when both household members work. Combining together the (relative) supply and demand parts of the model we are able to establish technological change (either biased or neutral) as a plausible explanation of recent trends in wage inequality.     

The Household, Time Use and Tax Policy

This paper is concerned with modelling household decisions andthe welfare effects of tax policy. It seeks to emphasise theimportance of a model that incorporates household productionand can take account of the evident female labour supply heterogeneityacross two-parent families. If, after having children, someproportion of households substitute domestic for market laboursupply, the income and consumption variables used as the taxbase in most countries may be poorly correlated with livingstandards. Taxes and welfare programs based on these variablesmay increase inequality by shifting the overall tax burden tolow and middle wage families with both partners in work, awayfrom families with much higher wages and in which only one memberworks to earn the same joint market income. The paper combinesdata on time use, income, taxes and benefits to show how theytrack female labour supply over the life cycle, resulting inmuch higher tax burdens on two-earner households.

Labour effects of foreign and domestic remittances – evidence from Pakistan

Remittances are playing an increasingly important role in the economies of developing countries. In this paper, we study the effects of these flows on Pakistan’s labour market. We employ the 2007–2008 Household Integrated Economic Survey and Probit as well as Propensity Score Matching techniques to examine the impact on labour participation, quantity of work and activities of working as well as non-active members of remittance-receiving households. We find that both foreign and domestic remittances tend to lower labour supply of the recipient households. This impact is higher among women and among the young. The impact is more pronounced in the rural areas. In addition, foreign remittances increase the likelihood of household members attending middle school. We also examine the quantity of labour supplied by the remittance-recipient households. Results show little difference in the number of months and days worked between the households receiving and not receiving remittances. Furthermore, we find that the likelihood of being self-employed and cultivating one’s own land is higher among remittance recipients. In sum, our analysis highlights a higher role of foreign remittances in the labour market as compared to internal remittances.     

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.     

A test of a unitary model on labour supply using the information of household decision-making systems

This article tests whether a unitary model is consistent with household behaviour using the data of two-earner couples. It focuses on the unitary model assuming that all family members have the same utility function. The analysis investigates the difference in a husband's and wife's labour supply between the household that determines the wife to be the main decision-maker and the household that selects a different decision-making system under the control of individual and household characteristics. The estimation employs a treatment effects model to consider the selectivity bias caused by unmeasured characteristics. Results show that the household with the wife as the main decision-maker increases the husband's working hours by 15% and decreases the wife's working hours by 59%, compared to the household that selects a different decision-making system. This implies that the unitary model is rejected. Additionally, the husband's wage rate, the husband's and wife's health status, and their gambling addiction determine the household decision-making system such as the variables that determine the reservation utility of not being married. The effect of the decision-making system on the labour supply and that of the determinant factors on the decision-making system are consistent with the implications obtained from Nash bargaining models and collective models.     

The Impact of Non-Labor Income Given Job Heterogeneity on Household Time Allocation: The Evidence from China

This paper proposes a theoretical framework based on new household economic theories. A dataset from the 2006 China Health and Nutrition Survey (CHNS) is used. Given heterogeneity in major family members’ jobs, the effect of non-labor income on household time allocation is discussed under two scenarios: jobs with flexible work hours and jobs with fixed work hours in the market. Based on the nature of the employer the major family member works for, employers can be categorized into four categories: government-owned, family contract, privately-owned, and foreign-funded. Each of the four categories is used for dissecting the data into different sets for analysis by category. The results imply that job heterogeneity is significantly correlated to household time allocation. An increase in non-labor income results in a decrease in the time allocated to housework for all households. However, leisure time is allocated differently among different households due to job heterogeneity. An increase in non-labor income leads to less leisure time for households working for government-owned or foreign-funded enterprises, and more leisure time for households working for family contract or privately-owned enterprises.     

Nonlinear taxes in a life-cycle consistent model of family labour supply

This paper deals with family labour supply under nonlinear income taxation in a life-cycle consistent framework. A major purpose of the paper is, therefore, to bring together previous research on how to model joint supply decisions, life-cycle consistency and piecewise linear taxation, and then perform an econometric application using Swedish cross-section data. The paper starts by constructing an intertemporal model of household behaviour, which is used to derive optimal hours of work for the husband and the wife, respectively. Then, given the appropriate theoretical framework, the model is specified in a way suitable for econometric analysis. Regarding the estimation results, we find that both male and female labour supply are sensitive not only to changes in the own marginal wage rate and the virtual nonlabour income, but also to changes in the marginal wage rate of the spouse. The latter means that cross-wage effects are important when it comes to interpret the consequences of income taxation.     

COMPUTATION OF NASH-BARGAINED MODELS OF HOUSEHOLD LABOUR SUPPLY*

This paper explores a method of recovering the structural parameters of a Nash-bargained model of household labour supply. It proceeds by computing the desired hours of labour supply numerically rather than analytically, thus circumventing the need for analytical tractability. This numerical procedure is then embedded in a conventional maximum-likelihood estimation to obtain estimates of the structural preference parameters. An example using Family Expenditure Survey data is reported.     

Real Estate Market Policy and Household Demand for Housing

This paper used an estimated mixed multinomial logit model of household housing demand to examine the impact of four housing market‐related policies on a stated preference survey sample. The estimated demand probability function suggested that household choice behaviour does show huge heterogeneity. The estimated results were then employed to examine the effects of the policies. We estimated the potential disequilibrium between demand and supply under the construction‐size‐limitation policy, demonstrated that the efficient movers' subsidy increases along with the household income, and simulated the changes in housing demand when tax policy is changed. We demonstrate the potential usefulness of our modelling framework in assisting policy‐making decisions. Our model also partially explains the failures and controversies of the latest real‐estate intervention policies in China.     

The Redistributive Effects of a Minimum Wage Increase in New Zealand: A Microsimulation Analysis

This paper examines the potential effects on inequality and poverty of a minimum wage increase, based on a microsimulation model that captures the details of household composition and the income tax and welfare benefit system and allows for labour supply responses. Results suggest that, largely due to the composition of household incomes, a policy of increasing the minimum wage has a relatively small effect on the inequality of income per adult equivalent person, and a money metric utility measure, using several inequality indices. Hence, the minimum wage policy does not appear to be particularly well targeted, largely due to many low wage earners being secondary earners in higher income households, while many low income households have no wage earners at all. These results are reinforced when allowing for wage spillovers further up the wage distribution. Nevertheless, a minimum wage increase can have a more substantial effect on some poverty measures for sole parents in employment.     

Population and house prices in the United Kingdom

Real house prices rise in the United Kingdom amid growing concern of an impending correction. The rate of household formation has increased with strong population growth, due to elevated rates of natural increase and net migration, and lack of growth in average household size, due to a rise in single‐person households with population ageing. This paper presents an overlapping generations model of housing, endogenous labour, savings and growth to analyse the effect of an increase in the household formation rate and speculative demand under rational expectations on house prices in a general equilibrium. We find that real house prices rise over time if the rate of household formation outstrips the rate of housing supply, but do not follow a speculative bubble path in the long run. The results explain why the upward trend in real house prices reflects market fundamentals and has continued despite population ageing as the number of working and retired households grows relative to the number of older people seeking to sell.     

Does religious faith affect household financial market participation? Evidence from China

Based on the 2013 China Household Finance Survey data, this paper investigates the impact of religious faith on household financial market participation and portfolio choice. The results show that religious faith can significantly promote household financial market participation. Besides, religious faith can increase the proportion of risky assets held by households, including equities. We also find that the need for social interaction and human capital accumulation can significantly induce religious residents to participate in financial markets and hold risky assets. Overall, our results reveal how faith affects household finance activities in China.     

Evaluating the Cost-Effectiveness of In-Work Benefits: A Simulation Study for Switzerland

Abstract. Income support for working low-income families (the 'working poor') is on top of the political agenda in Switzerland. The current social assistance system is considered inadequate to support working poor households. Several European countries have introduced in-work benefits in order to make work pay. Based on a structural labour supply model, this paper provides microsimulation results of the effects of introducing different schemes of in-work benefits. It turns out that adding a minimum hours requirement to the current social assistance system is the most cost-effective reform. One-third of expected costs can be attributed to behavioural changes in labour supply.     

A behavioural analysis of the subsistence standard of living

Subsistence is analysed as an endogenous variable, contraryto its conventional exogenous treatment. It is postulated thatthe subsistence-livers perceive their own standard of subsistence,direct their earnings behaviour towards attaining, maintainingor exceeding this standard and, thus, reveal the standard throughthis behaviour. The labour supply function of the working poor,which displays a forward-falling segment at low wages and anupward-rising segment at higher wages, is hypothesised to offermeasures of subsistence and survival standards. The conceptsare rationalised using Sen's concept of ‘freedom of choice’and Arrow's concept of ‘freedom as flexibility’.It is argued that at below-subsistence living, individuals lackfreedom of flexibility in choosing their preferences and thussuffer the loss of freedom of choice—while subsistenceoffers a reasonable minimum of this freedom, the freedom iscompletely lost at the lowest survival standard.     

Youth labour supply and the minimum hours constraint - the case of single males

Traditionally economists estimate labour supply functions by assuming that the observed working hours the desired working hours. But if employers require some minimum working hours, e. g. 40 hours a week,then the results obtained by the traditional approach will be misleading since the observed working hours might not be the desired working hours. This paper tests the hypothesis of no minimum hours constraint. It also develops an econometric model explicity considering the minimum hours while estimating a youth labour supply function.     

Unions, monetary shocks and the labour market cycle

This paper provides a new growth model by considering strategic behaviour in the supply of labour. Workers form a labour union with the aim of manipulating wages for their own benefit. We analyse the implications on labour market dynamics at business cycle frequencies of getting away from the price-taking assumption. A calibrated monetary version of the union model does quite a reasonable job in replicating the dynamic features of labour market variables observed in post-war U.S. data.
