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...

A large body of literature, mainly based on hospital costs, shows that time to death (TTD) is by far a better predictor of health spending than age. In this paper, we investigate if this finding holds true also in presence of outpatient costs (drugs, diagnostic tests and specialist visits). Our...

Understanding the role that drug adherence has on health outcomes in everyday clinical practice is central for the policy maker. This is particularly true when patients suffer from asymptomatic chronic conditions (i.e., hypertension, hypercholesterolemia, and diabetes). By exploiting a unique...

The increasing waves of globalization, the first taking place between the second half of the last century and WWI, and the second which has occurred since WWII until today, implied an unprecedented flow of goods and factors across international borders. The first episode of mass migration dates...

This paper studies the impact of municipal non-residential property taxation on firms' performance using a panel data of italian manufacturing firms in 2001-2010. In the spirit of Duranton et al. (2011), we use a pairwise spatial difference instrumental variable estimator which allows to tackle...

This paper investigates the impact of business property taxation on firms' performance using a panel of Italian manufacturing firms. To account for endogeneity in local taxation, we exploit a pairwise spatial differenced generalized method of moments estimator. As well as providing robust...
