data envelopment analysis (dea) is an eciency measurement tool for evaluation of similar decision making units (dmus). in dea, weights are assigned to inputs and outputs and the absolute eciency score is obtained by the ratio of weighted sum of outputs to weighted sum of inputs. in traditional dea models, this measure is also equivalent with relative eciency score which evaluates dmus in com...

This study assessed the technical effi ciency of family poultry production in NigerDelta, Nigeria. The technical effi ciency estimate shows that the technical effi ciency of family poultry ranges between 0.09 and 0.63, with mean of 0.22. This indicates that on the average, the respondents are 22% effi cient in the use of combination of their inputs. The elasticity estimate of 12.29 indicates th...

traditional dea models deal with measurements of relative eciency ofdmus regarding multiple - inputs vs. multiple-outputs. one of the drawbacksof these model is the neglect of intermediate products or linkong activities. af-ter pointing out needs for inclusion of them to dea models. we propose hybridmodel that can deal with intermediate products formally using this model wecan evaluate divisio...

This paper develops a theory in which shocks to the effi ciency of information acquisition by financial intermediation translate into business cycle fluctuations via capital reallocation. In our theory, under costly verification, the bank chooses to only monitor the returns of those entrepreneurs with insuffi cient net worth. This distorts the existing capital allocation among entrepreneurs of ...

A conceptual framework for crop production effi ciency was derived using thermodynamic effi ciency concept, in order to generate a tool for performance evaluation of agricultural systems and to quantify the interference of determining factors on this performance. In Thermodynamics, effi ciency is the ratio between the output and input of energy. To establish this relationship in agricultural sy...

The role of the dairy cow is to help provide high-quality protein and other nutrients for humans. We must select and manage cows with the goal of reaching the greatest possible effi ciency for any given environment. We have increased effi ciency tremendously over the years, yet the variation in productive and reproductive effi ciency among animals is still quite large. In part this is because o...
