The paper studies Non-Stationary Dynamic Factor Models such that: (1) the factors Ft are I(1) and singular, i.e. Ft has dimension r and is driven by a q-dimensional white noise, the common shocks, with q r, and (2) the idiosyncratic components are I(1). We show that Ft is driven by r-c...

We propose a new measure of the output gap based on a dynamic factor model that is estimated on a large number of U.S. macroeconomic indicators and which incorporates relevant stylized facts about macroeconomic data (co-movements, non-stationarity, and the slow drift in long-run output growth...

We develop the econometric theory for Non-Stationary Dynamic Factor models for large panels of time series, with a particular focus on building estimators of impulse response functions to unexpected macroeconomic shocks. We derive conditions for consistent estimation of the model as both the...

By representing a system of budget shares as an approximate factor model we determine its rank, i.e. the number of common functional forms, or factors and we estimate a base of the factor space by means of approximate principal components. We assume that the extracted factors span the same space...

This paper depicts � from a variety of viewpoints � the degree of indebtedness and potential financial vulnerabilities of households across the Italian regions. Micro-data from several sources suggest that the financial situation of Italian households shows striking differences at...

Italian Abstract: Tra la metà del 2013 e l’estate del 2014 gli indicatori qualitativi comunemente impiegati a fini di analisi della congiuntura economica avevano fornito segnali coerenti con un progressivo rafforzamento della ripresa ciclica. Nello stesso periodo, gli indicatori quantitativi...
