xsmle is a new command for spatial analysis using Stata. We consider the quasi-maximum likelihood estimation of a wide set of both fi xed- and random- eff ects spatial models for balanced panel data. Of special note is that xsmle allows to handle unbalanced panels thanks to its full...

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...

Extreme values are common in survey data and represent a recurring threat to the reliability of both poverty and inequality estimates. The adoption of a consistent criterion for outlier detection is useful in many practical applications, particularly when international and intertemporal...

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...
