Funzioni di distribuzione dei tempi di disoccupazione: analisi di periodi osservati e “simulati”

The paper presents a review of the models and the procedures to analyze data sets including only completed spells, or censored and completed spells, or only censored or incomplete spells of unemployment considering the case without covariates (such as age, sex, etc.). The distributions of the incomplete spells of employment were analysed considering one at a time the popular ones: beta, gamma, logistic, lognormal, normal, Pareto, extreme values, and Weibull. Moreover, sets of simulated spells were analysed to verify the values of the exit rate, i.e., the spells generated from a model of queue and simulated through a representative scheme of the flows in the labour market.
