| dc.description.abstract | We have linked survey sample data with employee data from administrative registers. The combined data sources are used to assess the quality on measured contractual working hours in the Norwegian Labour Force Survey (LFS). The data files are linked at the job-level. Information on contractual hours of work in the LFS is given by the employee himself or by a member of his household. In the register data, the employers report information on contractual hours of work to a central governmental agency. We therefore have two independent sources of contractual working hours. Measurement error is estimated from the differences between the two independent working hours variables. The quantitative assessment is based on the assumption that the register data is correct, but this assumption is discussed at some length. The results indicate that LFS survey-based mean contractual working hours generally are higher in the survey than in the register. Compared with register data reported from employers, some groups of employees seem to over-report contractual working hours. The differences vary with working time length and type of working time arrangements between industries and occupations. The measurement differences are greatest in jobs without a fixed number of hours per week, and generally in jobs with few hours per week. Proxy interviews 1 result in even larger divergences. | en_US |
