  • A Test for Multivariate ARCH Effects
  • 2005
  • Ingår i: Applied Economics Letters. - : Informa UK Limited. - 1350-4851 .- 1466-4291. ; 12:7, s. 411-417

    • This paper extends Engle's LM test for ARCH affects to multivariate cases. The size and power properties of this multivariate test for ARCH effects in VAR models are investigated based on asymptotic and bootstrap distributions. Using the asymptotic distribution, deviations of actual size from nominal size do not appear to be very excessive. Nevertheless, there is a tendency for the actual size to overreject the null hypothesis when the nominal size is 1% and underreject the null when the nominal size is 5% or 10%. It is found that using a bootstrap distribution for the multivariate LM test is generally superior in achieving the appropriate size to using the asymptotic distribution when (1) the nominal size is 5%; (2) the sample size is small (40 observations) and/or the VAR system is stable. With a small sample, the power of the test using the bootstrap distribution also appears better at the 5% nominal size.

  • Well-being and occupational roles among middle-aged women
  • 2005
  • Ingår i: Work. - Amsterdam : IOS Press. - 1051-9815 .- 1875-9270. ; 24:4, s. 341-351
  • Tidskriftsartikel (refereegranskat)abstract
    • One purpose of the present study is to explore the stability of the pattern of health/work and sickness absence among middle-aged women over a period of three years. Two hypotheses were tested: 1. that enduringly healthy working women would perceive more valued occupational roles and higher well-being than long-term sick-listed women, and 2. that high levels of well-being at baseline would predict enduring health and occupational role value at a 3-year follow-up. Middle-aged women (n = 208) answered a postal survey with the Role checklist, a well-being scale and questions about work and sickness situation. The results showed that there was a considerable variability in the pattern of health/work and sickness absence. The results showed that the enduringly healthy women experienced a more valued worker role and higher well-being than the long-term sick-listed women. Furthermore, high levels of well-being concerning health and work predicted enduring health in the studied sample.

  • Incidence and risk factors for depression and anxiety disorders: Results from a 34-year longitudinal Swedish cohort study.
  • 2005
  • Ingår i: Aging & Mental Health. - : Informa UK Limited. - 1364-6915 .- 1360-7863. ; 9:6, s. 571-575
  • Tidskriftsartikel (refereegranskat)abstract
    • This study is based on a total cohort (N = 192) of people born in 1902 and 1903 and living in southern Sweden. Subjects were assessed at baseline when 67 years of age and on eight further occasions over 34 years or until death. The participation rate in the nine examinations ranged from 78-100%. Interviews, psychological tests, and medical examinations were used as well as information on medical diagnoses from primary health care records and hospital records. The cumulative probability for the development of clinical depression during the follow-up was 8% and for anxiety 6%. The incidence rate for depression and for anxiety was highest during the period 67-81 years. Persons with poor financial status were more likely to be diagnosed with depression but no significant risk factor for anxiety was found. Only 14% developed depression and anxiety during the follow-up period, females more often than men. The strongest risk factors for the development of depression were perceived economic problems.
