Generalised commensurability properties of efficiency measures: Implications for productivity indicators
نویسندگان
چکیده
We analyse the role of new weak and strong commensurability conditions on efficiency measures especially productivity measurement. If fails, then a index (indicator) may exhibit homogeneity bias yielding inconsistent contradictory results. In particular, we show that Luenberger indicator is sensitive to proportional changes in input-output quantities, while Malmquist not affected by such changes. This due degree directional distance function under constant returns scale. only satisfies axiom general. However, if diagonally homogeneous technology, commensurability. explains why direction an arithmetic mean observed data works well. Numerical examples empirical illustration are proposed. Under translation homothetic any additive transformation observations.

Response of Soil Properties and Microbial Communities to Agriculture: Implications for Primary Productivity and Soil Health Indicators
Agricultural intensification is placing tremendous pressure on the soil's capacity to maintain its functions leading to large-scale ecosystem degradation and loss of productivity in the long term. Therefore, there is an urgent need to find early indicators of soil health degradation in response to agricultural management. In recent years, major advances in soil meta-genomic and spatial studies ...
