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...

This paper combines survey and register data from a Norwegian randomized field trial to evaluate the performance of parametric and semi-parametric sample selection estimators commonly used to correct for attrition bias.

In a large representative sample of young Norwegian workers, we estimate gross transitions to unemployment, education, and other exits in a multinomial logit. In line, with received literature, we find that individuals with high education, experience, and income have significantly lower...

We explore optimal search for individual improvement when agents start with different confidence in own ability. The initial self-confidence may be determined by nature or socio-economic factors.

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.

We investigate induced retirement effects of the Norwegian early retirement program "AFP" and emphasize effects caused by relocations of some individuals from disability pension and unemployment to AFP. Our theoretical model predicts that AFP unambiguously induces more early retirement.

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.

This paper uses data from a natural experiment to investigate the potential incentive effect of a fixed unemployment insurance period. We compare two large groups of Norwegian unemployed persons who registered as unemployed in 1990 and 1991. The last group was affected by a rule change that in...

The organisation of the paper is as follows. Section II provides a short review of the job search and job-match theory, together with a discussion of previous empirical findings. In Section III, we give a brief description of some institutional features of the Norwegian educational system and...
