Negative duration dependence in the exit rate from social assistance is an important issue addressed in the dynamic welfare participation literature. If heterogeneity is properly modelled, the decline of the exit rate is ascribed to a progressive reduction of the capability to get off welfare...

While a vast literature has analysed the wage and employment effects of active labor market programs (ALMPs), a welfare analysis of such programs is seldom implemented (Kluve and Schmidt, 2002). In an attempt to measure the welfare effect of a wage subsidy on youth labor, this paper performs a...

Questo articolo stima le probabilità di entrare e uscire dallo stato di povertà (poverty dynamics) e la sua persistenza in Italia negli anni ‘90, attingendo dalle fonti longitudinali dello European Community Household Panel, 1994-2001. Combinando le stime dei tassi di uscita con quelli di...

An urn-ball probabilistic model of the labour market is developed. Agents can be employed, (voluntary or involuntary) unemployed or entrepreneurs. The analytical long run equilibrium probabilities for each state and the matching function are derived. Then, the out-of-equilibrium dynamics are...

In linked employer-employee databases, when the employees are sampled first and then the employers data are attached, the set of firms that enter the sample is biased towards the large dimension. In this paper I discuss two strategies to impute inflating factors to the employers’ records, and...

Multiplicative models of firm dynamics ‘à la Gibrat’ have become a standard reference in industrial organization. However, some unpleasant properties of their implied dynamics – namely, their explosive or implosive behaviour (firm size and number collapsing to zero or increasing...

In this paper I review the main strengths and weaknesses of agent-based computational models. In particular I rationalise the main theoretical critiques, which point to the following problematic areas: (i) interpretation of the simulation dynamics, (ii) estimation of the simulation model, and...
