A panel data study of physicians' labor supply: the case of Norway.

Physicians are key personnel in a sector which is important due to its size as well as the quality of service it provides. We estimate the labor supply of physicians employed at hospitals in Norway, using personnel register data merged with other public records. A dynamic labor supply equation is estimated using a sample of 1303 male physicians observed over the period 1993-1997. The methods of estimation are GMM and system GMM. We reject the static model in favor of a dynamic model and obtain short run wage elasticities around 0.3. This is higher than previously estimated for physicians, in particular for those who are not self-employed.

Unemployment, labor force composition and sickness absence: a panel data study.

Sickness absence tends to be negatively correlated with unemployment rates. In addition to pure health effects, this may be due to moral hazard behavior by workers who are fully insured against income loss during sickness and to physicians who meet demand for medical certificates. Alternatively, it may reflect changes in the composition of the labor force, with more sickness-prone workers entering the labor force in upturns. A panel of Norwegian register data is used to analyze long-term sickness absences. The unemployment rate is shown to be negatively associated with the probability of absence, and with the number of days of sick leave. Restricting the sample to workers who are present in the whole sample period, the negative relationship between absence and unemployment becomes clearer. This indicates that procyclical variations in sickness absence are caused by established workers and not by the composition of the labor force.

Diagnosis and duration of sickness absence as predictors for disability pension: results from a three-year, multi-register based* and prospective study.

AIM: A study was undertaken to identify predictors for the transition from long-term sickness absence into disability pension with special emphasis on routinely collected medical information (e.g. diagnoses on sickness certificates) and the duration of sickness-absence spells. METHODS: The study used a 10% random sample of the Norwegian population of working age (the KIRUT database). Individuals below 60 years of age, with spells of long-term sickness absence starting in 1990-91, where the medical diagnoses on the sickness certificates were known, were identified. This group (4,432 men and 5,645 women) was followed up for three years after the end of sickness absence with regard to disability pension and working status. RESULTS: In logistic regression the following predictors significantly increased the risk of obtaining disability pension during the first three years after the long-term sickness spell: age, part-time employment, and duration of absence > 197 days. Higher education and having children < 11 years significantly decreased the risk. Having the medical diagnoses "mental problems" and diseases in the nervous system, respiratory system, and circulatory systems indicated high risk (compared with musculoskeletal disease). The diagnostic groups "pregnancy-related disease" and "injuries" implied low risk for disability pension. In separate regressions for both genders the "protective effect" of having small children remained only for women. High risk for sickness absence caused by "mental problems" reached significance only for men. CONCLUSIONS AND IMPLICATIONS: Several risk factors for transition from long-term sickness absence into disability pension were identified. The finding that spells of sickness absence with duration up to seven months did not imply increased risk of disability during the first three years may have implications for interventions aimed at long-term sickness absentees.

The role of gender in long-term sickness absence and transition to permanent disability benefits. Results from a multiregister based, prospective study in Norway 1990-1995.

BACKGROUND: The aim of the study was to identify predictors for the transition from long-term sickness absence into disability pension with a special focus on gender. METHODS: The study used data from a national database containing a 10% random sample of the Norwegian adult population (The KIRUT database). The study population were all individuals in the database who on 1 January 1990 were eligible for sick pay from the Norwegian National Insurance System: 83,398 men and 75,586 women. Individuals below 60 years with long-term sickness absence starting in 1990 and 1991 were identified, 6,434 men and 8,233 women, and followed up for three years. Background data were used as independent variables in a logistic regression of the probability for receiving disability pension during follow-up. RESULTS: Annual cumulative incidence of long-term sickness absence was 6.5% for women and 4.9% for men. During follow-up, 12.4% of the women and 12.6% of the men received disability pension. Among full-time employed women only 10.3% had become disability pensioners, while the corresponding proportion for women working part-time was 15.5%. For men the figures were 12.1% (full-time) and 18.1% (part-time). In the logistic regression of the whole sample the female odds ratio was insignificant. The dominant predictive factors for disability pension were age and duration of the sickness spells. Working part-time also increased the risk. Higher levels of education and having children below 7 years reduced the probability for disability pension. Separate regressions for men and women showed that the 'protective' effect of having small children only remained for women.
