This paper explores a process which I denote as “young workforce disposal” (YWD). YWD reflects the fact that many young people enter the labor market as dependent employees, at some later time they are dismissed and (presumably) move into never-ending unemployment. Long term unemployment may...

L'aggancio tra i dati WHIP e quelli del Casellario degli Attivi consente l'osservazione di tutti i percorsi lavorativi, non solo quelli coperti dai dati INPS (o WHIP). Questa procedura ha permesso di dare una parziale risposta ad una domanda che ci si pone quando si usano i dati WHIP, o di fonte...

In questo rapporto si presentano due informazioni sviluppate partendo dagli archivi degli episodi di lavoro dipendente di WHIP (archivi RL_annui_): gli oneri sociali obbligatori (variabile oneri_sociali) e il costo del lavoro (variabile costo_lavoro). Le stime degli oneri sociali obbligatori e...

The paper explores the fit properties of a class of multivariate Lévy processes, which are characterized as time-changed correlated Brownian motions. The time-change has a common and an idiosyncratic component, to re ect the properties of trade, which it represents. The resulting process may...

This paper is about very long term unemployment (a more appropriate denomination could be "out-of-official-employment") in Italy, its concentration and the process of young worker disposal, an important, yet unexplored, determinant. “Very long” is not just “long”: we are dealing with...

This paper constructs a class of multivariate Gaussian marked Poisson processes to model asset returns. The model proposed accommodates the cross section properties of trades, allows for returns to be correlated conditional on trading activity, and preserves the economic intuition of normality...

This paper explores the “disposable” patterns of workforce utilization in Italy. The term “disposable” reflects the fact that people enter the labor market, their services are “used” as a disposable commodity for few years, after which they leave the labor market and are no longer...

A definition of set-wise differentiability for set functions is given through refining the partitions of sets. Such a construction is closely related to the one proposed by Rosenmuller (1977) as well as that studied by Epstein (1999) and Epstein and Marinacci (2001). We present several classes...

The traditional multivariate Lévy process constructed by subordinating a Brownian motion through a univariate subordinator presents a number of drawbacks, including the lack of independence and a limited range of dependence. In order to face these, we investigate multivariate subordination,...
