Spatial-temporal Stochastic Frontier Models
The stochastic frontier model with heterogeneous technical efficiency explained by exogenous variables is augmented with a sparse spatial autoregressive component for a crosssection data, and a spatial-temporal component for a panel data. An estimation procedure that takes advantage of the additivity of the model is proposed, computational advantages over simultaneous maximum likelihood estimat...
متن کاملInferences from Cross-Sectional, Stochastic Frontier Models
Conventional approaches for inference about efficiency in parametric stochastic frontier (PSF) models are based on percentiles of the estimated distribution of the one-sided error term, conditional on the composite error. When used as prediction intervals, coverage is poor when the signal-to-noise ratio is low, but improves slowly as sample size increases. We show that prediction intervals esti...
متن کاملA Laplace Stochastic Frontier Model
We propose a Laplace stochastic frontier model as an alternative to the traditional model with normal errors. An interesting feature of the Laplace model is that the distribution of inefficiency conditional on the composed error is constant for positive values of the composed error, but varies for negative values. Therefore, it may be ideally suited for analyzing industries with many forms on o...
متن کاملSpatial Databases, The Final Frontier
During the last decade database systems are used to represent spatial information mainly in the twodimensional plane or the three-dimensional space. Applications that rely on spatial databases can be found in CAD-CAM, VLSI, robotics, historical databases, geographical information systems, architectural sciences, visual perception and autonomous navigation, tracking, environmental protection and...
متن کاملTowards a Frontier of Spatial Scientometric Studies
The research field of spatial scientometrics is dedicated to measuring and analyzing science with spatial components (e.g., location, place, mapping). It involves the study of spatial patterns, impacts and trends of scientific activities (e.g., co-publication, citation, academic mobility) based on bibliographic databases. Because of the dynamic nature of this field, researchers from interdiscip...
