Negli archivi amministrativi dell’INPS, e in particolare nei dati dell’Osservatorio delle Imprese, il settore di attività economica è identificato in base a diverse classificazioni. I dati più recenti riportano la codifica Ateco 2002, validata dall’ISTAT nell’ambito del progetto ASIA...

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 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...

In this paper we document a common sense idea: When an individual is searching for a new job, the longer it takes the more s/he will be available to adapt her/his skills, often with a worsening in status and/or wage. We used a dataset of administrative source, containing a sample of individuals'...

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...
