This paper describes sfcross and sfpanel, two new Stata commands for the estimation of cross-sectional and panel data stochastic frontier models. sfcross extends the offi cial frontier capabilities by including additional models (Greene 2003; Wang 2002) and command functionality, such as the...

The main objective of this article is to evaluate to which extent the set of national and regional cost control policies implemented in recent years in Italy have affected hospital activity. Our contribution is mainly empirical as we focus our attention on the impact that policies like hospital...

This paper proposes a stochastic frontier panel data model in which unit-specific inefficiencies are spatially correlated. In particular, this model has simultaneously three important features: i) the total inefficiency of a productive unit depends on its own inefficiency and on the inefficiency...

The classical stochastic frontier panel data models provide no mechanism for disentangling individual time-invariant unobserved heterogeneity from inefficiency. Greene (2005a, b) proposed the ‘true' fixed-effects specification, which distinguishes these two latent components while allowing for...

During the Covid-19 pandemic, several countries have resorted to self-adaptive mechanisms that allow non-pharmaceutical interventions to be tailored to local epidemiological and health care indicators. These mechanisms reinforce the interdependence between containment measures and the evolution...

The paper presents the main results of the Eurosystem's Household Finance and Consumption Survey (HFCS) with an emphasis on the data for Italy in the international context. The paper examines households' socio-demographic characteristics, assets and income distribution, participation in real and...

Nell'ultimo decennio, ma soprattutto nella recente crisi economica mondiale, il divario tra l'industria del Mezzogiorno e quella del Centro Nord si è ampliato: gli investimenti e l'occupazione industriale si sono ridotti in misura assai più intensa che al Centro Nord; il contributo delle...
