Productivity and efficiency are key performance indicators of improved seeds. Efficiency differences explain part of the variation in productivity. Improved seeds may affect efficiency because farmers often do not apply inputs at optimum. Improved seeds therefore not only directly affect...

Increasing food demand will most likely be met with agricultural intensification and land clearing, exacerbating environmental consequences associated with food supply. The mechanisms and trade-offs between agriculture and the environment are heterogeneous and not well understood, yet key to...

This article provides a generalization of the materials balance-based production model introduced by Coelli et al. (2007). Based on this, some new environmental efficiency (EE) measures are presented. The Coelli et al. (2007) EE measure and its extension by Rødseth (2016) produce biased...

Agricultural inputs are peculiar in nature as an asymmetry in their roles can be identified during the production process. These inputs can be grouped into a set of growth inputs or a set of facilitating inputs. The inputs affecting biological or physiological growth from the inside of the plant...

In this contribution, first the concept of returns to growth (RTG) of a high-tech firm facing hyper-competition in the new economy is introduced by describing a proportional relationship between growth in inputs and growth in outputs using the growth efficiency (GE) model of Sengupta (2002)....

The interest in promoting food and water security through development projects has led to the need to evaluate the impact of these projects. This study evaluates the impact from transitioning to a modern irrigation technology. Deciding to adopt or not an alternative irrigation technology...

This paper estimates a quadratic stochastic frontier production function to examine the determinants of technical efficiency in rice farming in Bangladesh using the computer program FRONTIER 4.1. Primary data has been collected using multi-stage random sampling technique from twelve villages in...

This paper investigates the differences in technical efficiency and productivity change, and the technology gaps, between French and Hungarian farms in the dairy and cereal, oilseed and protein crops (COP) sectors during the period 2001–2007. The analyses were performed with national Farm...
