This study deals with modelling of neoclassical labour supply models for one-adult and two-adult households. A standard labour supply model is presented and estimated on Dutch data from 1985. A modification of the standard model is formulated, taking explicit account of nonconvexities in the budget set, related to the Dutch social security and welfare system. Habit formation and interdependent preferences are analyzed and a structural model of job choice, labour supply and wages is developed by incorporating nonpecuniary job characteristics into a utility maximization model. A full simultaneous model of labour supply in wage determination is estimated, based on the premise that individuals are faced with a limited availability of jobs. This microeconomics, econometrics and labour economics study is intended for the use of researchers.

One of the major issues of policy makers in The Netherlands is to reduce the high unemployment rate. In 1988 economic growth was substantial in all OECD countries, which led to an increase in employment. The economic growth also induced extra labour supply, especially of married women, which altogether led to a smaller reduction in the unemployment rate than could have been expected in view of the economic growth (see Rapportage Arbeidsmarkt, 1989). The estimated official unemployment rate in 1988 is still 11. 0% of the total labour force. Therefore, there is a strong interest in policies that seek to increase employment (the demand side of the labour market) as well as in understanding the factors that influence labour supply. In this thesis we try to further such understanding by constructing a detailed model of household labour supply. The data we use relate t9 Dutch households in 1985. In that year the official rate of unemployment was 15. 9%. A distinguishing feature of Dutch labour supply is its very low level of female labour force participation, e. g. in 1985 it was only 35. 2%. Apart from Spain, which had a similar participation rate, most other industrialized OECD countries had a participation rate of around 60% (see OECD Labor Force Statistics).
