Parametric stochastic frontier models yield firm-level conditional distributions of inefficiency that are truncated normal. Given these distributions, how should one assess and rank firm-level efficiency? This study compares the techniques of estimating (a) the conditional mean of inefficiency...

The reform-process towards a higher world-market orientation has a long tradition in Chile, with all its strengths and weaknesses. The food processing industry is highly competitive on the worldmarket. The following paper investigates the technical efficiency of the Chilean food processing...

The rapid growth of human population has impacted on global food security, development and health. Therefore, efforts to achieve the sustainable development goals of reducing poverty and hunger needs to particularly focus on the critical linkages between agriculture, nutrition, health and...

We consider estimation of a panel data model where disturbances are spatially correlated in the cross-sectional dimension, based on geographic or economic proximity. When the time dimension of the data is large, spatial correlation parameters may be consistently estimated. When the time...
