This paper examines the empirical importance of randomisation bias in a Norwegian randomised field trial on a rehabilitation programme for sick listed worders. Inclusion of participants in the trial was base on information obtained from administrative social insurance records. Professional...

Sample attrition is a potential source of selection bias in experimental as well as non-experimental programme evaluation. For labour market outcomes such as employment status and earnings, missing data problems caused by attrition can be circumvented by collection of follow-up data from...

Establishing causal relationships in social policy evaluation is important, but difficult due to sample selection. To evaluate the performance of estimators designed to handle sample selection bias we analyse data from a Norwegian rehabilitation project with a randomised experimental design. The...

In this paper we evaluate a Norwegian vocational rehabilitation program by comparing employment outcomes of trainees and nonparticipants using nonexperimental data. A matching estimator is used to calculate the training effect for different subgroups of the sample. We demonstrate how bounding...

The paper discusses how this relatively strong price response should be interpreted in the context of other econometric analysis with no explicit appliance dependence. Finally, the significance of the many household charcteristics at both stages of the model signals a high degree of...

We evaluate the costs of three different programs for alleviating long term poverty: (i) workfare, or grants made contingent on a work requirement, (ii) universal welfare, or unconditional grants, and (iii) means-tested welfare, or grants conditioned on private labor market earnings. We identify...

Empirical studies in family economics usually rely on questionnaires, statistical or panel data. Here we try to study experimentally some crucial aspects of engaging in a marriage. First the female partner can end the relationship or suggest one of the two forms of joint venture. Whereas a full...

We investigate the intergenerational welfare implications of Generational Accounting when it is used as the basis of intertemporal fiscal policy decisions. In particular, we consider an economy with a PAYGO social security system out of steady state due to a permanent fall in fertility.

Sick leaves may vary over the business cycle due to disciplining effects or changes in labour force composition. The latter hypothesis maintains that sickness may be pro-cyclical due to employment of "marginal" workers with poorer health whrn demand increases.

In this paper we evaluate the effectiveness of educational programs used as an employment strategy for diabled workers in Norway. To obtain these estimates we follow the employment career of a sample of participants in educational programs and nonparticipants three years after they had left the...
