While technical efficiencies of firms that are estimated with respect to a given frontier are comparable, this is not normally valid the case among firms that operate under different technologies. Such problem arises when comparisons of firms from different regions of country are involved. This study uses the concept of the metafrontier function to investigate regional differences in milk produ...

There have been many previous studies of technical inefficiency in rice production in the Philippines, but none has focused simultaneously on production risk and technical inefficiency at the farm level. In this study, we analyse technical inefficiency in a rainfed lowland rice environment in Central Luzon using a stochastic frontier production function with a heteroskedastic error structure.

The aim of this study is to investigate the context by which veterinary services may affect technical efficiency (TE) of Iranian dairy farms. A data envelopment analysis (DEA) was applied to a random sample of 840 dairy farms from six provinces across Iran to estimate regional frontier and metafrontier production functions and also to calculate corresponding TE of these farms. The relationship ...

in this study, farm level technical efficiency (te) and its determinants were investigated. a stochastic cobb-douglas (cd) production frontier was used to provide estimates of input-oriented te for a sample of 100 rain fed farms in two palestinian governorates. empirical findings showed that the estimated te of the farms in the pooled sample ranged from 35.7 to 95.6%, with a mean value of 72.2%...

The main objective of the present study was to investigate the production and marketing of Iranian saffron. About 99% of Iranian saffron is produced in Khorasan Province. Therefore, Khorasan was selected for the current study. Data were collected through the stratified random sampling method from 232 saffron producers in Torbat Heidarieh, Ghaenat and Gonabad regions through interviews in fall 1...
