摘要:
ABSTRACTCompeting‐risks models are becoming increasingly pervasive in applied research to explain the factors determining both the time in a state (i.e. unemployment) and the exit route from the state (is. leaving unemployment for a job or non‐participation). However, as in many limited dependent variable models, the interpretation of the covariate estimates requires care. Despite assertions to the contrary in many published papers, it is shown that the estimated qualitative effect of a covariate on the hazard for riskjtypically conveys no information on its qualitative effect on either the likelihood of, or expected time until, exit viaj.This is because such magnitudes depend on the qualitative and quantitative effects of the covariate on other risks which cannot be ignored. The point is demonstrated by using UK data on the unemployment to re‐employment transitions of a sample of male job l
