This paper proposes a new method for estimating a full-coverage spatial price index using data typically available in household budget surveys. The food component of the index is estimated at the household level using reported expenditures and …
This research introduces a minimum Hellinger divergence estimator for stochastic frontier models. The study establishes the strong consistency and asymptotic normality of this estimator under certain regularity conditions. Furthermore, it explores …
In recent decades, the estimation of causal effects has attracted increasing professional interest. However, the success of this effort depends on the ability to generate precise estimates that can aid in the implementation of new laws and …
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 …
