The first part of this paper concentrates on modeling transitions out of unemployment using aggregated gross flow data. Models are estimated using monthly transition probabilities for March-April 1984. This analysis produces evidence consistent with negative duration dependence but sheds no light on the role of macroeconomic factors. The second part focuses on this issue. A time-series analysis of the proportion of long-term unemployment, using data for four age and sex groups, provides evidence that a proportionately has been associated with reduction in job availability.
