The study sought to establish the level of technical, allocative, and economic efficiencies in irrigated onion production southern Ethiopia, as well identify sources inefficiencies. cross-sectional data were obtained from a total 165 random farmers selected Humbo area. parametric stochastic frontier model was used estimate efficiency levels, whilst two-limit Tobit utilized determinants acquired...

Nowadays, container terminals are subject to extensive technological changes and specific transformations. Changes applied tend increase their ability offer high- end personalized services the customers finally affect competitiveness. The estimation of efficiency corresponds terminals’ production with a level inputs has been topic many studies, especially those conducted on wider regional or gl...

Small-scale potato farming in the Arfak Mountains needs attention allocating inputs for efficient farming. This study aims to describe allocation of use inputs, analyze factors that affect production, and level technical efficiency Mountains. Regency was chosen purposively as research location. Data collection starts from December 2021 February 2022. Sampling done by snowball sampling with a sa...

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...
