Incidence and duration of unemployment spells: Implications on the wage differentials of part-time and full-time workers

This article analyzes the extent to which incidence of unemployment and duration of unemployment spells affect the wage differentials between full-time and part-time workers. The estimation results of a sample selectivity bias-adjusted wage equation reveal that high incidences of unemployment are associated with low wages for both full-time and part-time workers. However, the reduction in wages due to incidence of unemployment is larger for full-time workers in high-paid jobs than for their part-time counterparts. Duration of unemployment spells affects full-time and part-time workers differently. In general, longer unemployment spells tend to increase the wages of full-time workers but tend to depress the wages of part-time workers. Although the probability of unemployment is not a factor in explaining the wage differential, the duration of unemployment accounts for a substantial portion (about 66.6% in full sample) of the wage differential that exists between full-time and part-time workers.
