The paper presents a metafrontier production function model for farm’s different groups having different technologies. The metafrontier model enables the computation of comparable technical efficiencies for farms operating under different technologies. The model also enables the technology gaps to be estimated for wheat farms under different technologies relative to the potential technology ava...

Purpose The Spanish airport system contains several regional airports within an amenity distance and alternative travel modes. Profitable cross-subsidise small airports, which are not required for development or connectivity. Airports government-owned centralised-managed by Air Navigation (AENA, its acronym). This study aims to analyse the probability of under-used public infrastructure AENA’s ...

Abstract Symmetric noise is the prevailing assumption in production analysis, but it often violated practice. Not only does asymmetric cause least-squares models to be inefficient, can hide important features of data which may useful firm/policymaker. Here, we outline how introduce into a or cost framework as well develop model inefficiency said models. We derive closed-form solutions for convo...

This study reports the results of farmers’ production via irrigation resources utilization and efficiency parameters technical allocative by way sustainable environmental economics. The hypothesis is that factors affect in scheme as Data from cross section panel data were used then productivity measurement function are outlined two scenarios: first, report such output elasticity determine ineff...
