   Sammanfattning : Effects of Renewable Benefit Periods and Labour Market Programmes on the Exit Rate from UnemploymentThe main question addressed in this paper concerns the incentive effects of time-restricted unemployment benefits, as manifest in a rising exit rate from unemployment to employment when the moment of benefit exhaustion approaches: are these incentive effects lost when participation in labour market programmes is at hand as a way of renewing benefit eligibility? This renewal possibility is available as part of the Swedish unemployment insurance system. A piecewise-constant, proportional competing-risks hazard model is estimated using Swedish administrative data generated during the period 1994-1997. LÄS MER

The overall aim of this thesis was to evaluate the development of mortality in Swedish dairy herds and to identify characteristics associated with on-farm mortality at cow and herd levels. LÄS MER

7. 20. Five essays on models and methods for the analysis of survival data with single and multiple causes of failure : With applications in family demography
