Labour supply and taxes

In this paper we provide an overview of the literature relating labour supply to taxes and welfare benefits with a focus on presenting the empirical consensus. We begin with a basic continuous hours model, where individuals have completely free choice over their hours of work. We then consider fixed costs of work, the complications introduced by the benefits system, dynamic aspects of labour supply and we place the analysis in the context of the family. The key conclusion of this work is that in order to estimate the impact of tax reform and be able to generalise results, a structural approach that takes account of many of these issues is desirable. We then discuss the 'new Tax Responsiveness' literature which uses the response of taxable income to the marginal tax rate as a summary statistic of the behavioural response to taxation. Underlying this approach is the unsatisfactory nature of using hours as a proxy for labour effort for those with high levels of autonomy on the job and who already work long hours, such as the self employed or senior executives. After discussing relevant theory we then provide a summary of empirical estimates and the methodology underlying the studies. Our conclusion is that hours of work are relatively inelastic for men, but are a little more responsive for married women and lone mothers. On the other hand, participation is quite sensitive to taxation and benefits for women. Within this paper we present new estimates form a discrete participation model for both married and single men based on the numerous reforms over the past two decades in the UK. We find that the participation of low education men is somewhat more responsive to incentives than previously thought. For men with high levels of education, participation is virtually unresponsive; here the literature on taxable income suggests that there may be significant welfare costs of taxation, although much of this seems to be a result of shifting income and consumption to non-taxable forms as opposed to actual reductions in work effort

The Intensive and Extensive Margin of European Labour Supply

Labour supply is determined by two factors: the participation of workers in the labour market (extensive margin), and the number of hours supplied by those working (intensive margin). Based on the European Union Labour Force Survey (EU-LFS), we analyse which margin is more decisive in determining overall labour supply in 24 Member States. The results reveal large diff erences between countries, even after controlling for composition effects in terms of socio-demographic and household characteristics. In addition to individual labour supply, our focus is on differences between EU Member States concerning household labour supply. Joint determination of the number of hours worked between spouses can be observed for dual-income couples in Austria, the Netherlands and Spain.Female labour supply; household labour supply; European Union; EU-LFS

High Wages - An instrument inducing workers to work more?

Wages and their effect on labour supply are not only an important subject for labour economists who aim at measuring substitution and income effects. Additionally, the government is interested in the impact of policy changes on the labour market and companies would like to know if it is possible to increase labour supply and especially productivity by increasing the wage rate. This paper introduces a dynamic version of the traditional model of labour supply and presents model extensions and the underlying behavioural assumptions arising from empirical findings, psychology and neuroscience. It evaluates findings and behavioural assumptions derived so far. None of the contributions investigated in this work is entirely free from criticism. The problem of analysing a comprehensive model of labour supply on the one hand, is the scarcity of suitable subjects to investigate and on the other hand, the individuality of each subject observed. With this work a critical analysis of existing research on labour supply decisions is provided. This shall contribute to motivate and ease future research in this area which has to take these problems into account.high wages; analysis; labour supply decision; labour supply model; intertemporal labour supply

Job changes, hours changes, and the path of labour supply adjustment

This paper uses the first twelve waves of the British Household Panel Survey covering the period 1991-2002 to investigate single women’s labour supply changes in response to three tax and benefit policy reforms that occurred in the 1990s. We find evidence of small labour supply effects for two of such reforms. A third reform in 1999 instead led to a significant increase in single mothers’ hours of work. This increase was primarily driven by women who changed job, suggesting that labour supply adjustments within a job are harder than across jobs. The presence of hours inflexibility within jobs and labour supply adjustments through job mobility are strongly confirmed when we look at hours changes by stated labour supply preferences. Finally, we find little overall effect on wages

Tax Policy and Returns to Education

This paper considers how asymmetric tax treatment, where labour market earnings are taxed but household production is untaxed, aspects educational choice and labour supply. We show that taxes on labour market earnings can generate a large (non-marginal) switch to home production and the ensuing deadweight losses are large. Using a cross-country panel, we find that gender differences in labour supply responses to tax policy can explain differences in aggregate labour supply and years of education across countries.Increasing returns; tax policy; gender; labour supply; education

The Labour Supply of Sex Workers in Cape Town

Traditional labour economics predicts that the supply of labour will increase as earnings increase. However, labour supply need not be positive, especially if workers make decisions based on short-term income targets. Income targeting may best describe jobs where workers decide on working hours and where wages are uncorrelated across days. This paper examines the labour supply of sex workers in Cape Town, whose working conditions largely fulfill these criteria. Contrary to traditional economic theory, we find evidence of a negative labour supply curve.Labour supply, sex workers, hyperbolic discounting

Did Working Families' Tax Credit work? Analysing the impact of in-work support on labour supply and programme participation

With micro-data from before and after a major reform in 1999 to the structure and form of in-work transfers in the UK, this paper uses a structural model of labour supply and programme participation to show the impact of a reform to in-work support (Working Families' Tax Credit) on both labour supply and programme participation (or take-up). Estimates suggest that the changes in in-work incomes through the introduction of WFTC increased labour supply of lone mothers by around 4.6 percentage points, slightly reduced labour supply of mothers in couples by 0.2 percentage points, and increased the labour supply of fathers in couples by 0.8 percentage points, equivalent to a net increase in participation of 94,000 workers. Participating in Family Credit, the UK's in-work programme before October 1999, conferred a utility loss as well as a utility gain from the extra income, but we find this utility cost of participation to be lower under WFTC

Labour supply and employment in the euro area countries - developments and challenges

The aim of this report, which has been prepared by a Task Force of the Monetary Policy Committee of the Eurosystem, is to describe and analyse the main developments in labour supply and its determinants in the euro area, review the links between labour supply and labour market institutions, assess how well labour supply reflects the demand for labour in the euro area and identify the future challenges for policy-makers. The data available for this report generally cover the period from 1983 to spring 2007.

The Predictive Value of Subjective Labour Supply Data: A Dynamic Panel Data Model with Measurement Error

This paper tests the predictive value of subjective labour supply data for adjustments in working hours over time. The idea is that if subjective labour supply data help to predict next year's working hours, such data must contain at least some information on individual labour supply preferences. This informational content can be crucial to identify models of labour supply. Furthermore, it can be crucial to investigate the need for, or, alternatively, the support for laws and collective agreements on working hours flexibility. In this paper I apply dynamic panel data models that allow for measurement error. I find evidence for the predictive power of subjective labour supply data concerning desired working hours in the German Socio-Economic Panel 1988-1996.Labour Supply, Subjective Data, Measurement Error, Dynamic Panel Data Models

Adieu Rabenmutter - The Effect of Culture on Fertility, Female Labour Supply, the Gender Wage Gap and Childcare

This paper studies the effect of cultural attitudes on childcare provision, fertility, female labour supply and the gender wage gap. Cross-country data show that fertility, female labour force participation and childcare are positively correlated with each other, while the gender wage gap seems to be negatively correlated with these variables. The paper presents a model with endogenous fertility, female labour supply and childcare choices which fits these facts. There may exist multiple equilibria: one with zero childcare provision, low fertility and female labour supply and high wage gap, and one with high childcare provision, high fertility and female labour supply and low wage gap.cultural preferences, fertility, female labour supply, wage gap, childcare
