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...

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...

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...

Identifying how efficient public schools are - that is, the academic performance they can generate with the available inputs - is relevant information for designing public policies to improve education quality. Using a two-stage data envelopment analysis (DEA) and the Malmquist index, this study...
