of scale elasticity and returns to scale are inextricably related to the conditions of the stages of production. Thus, an … evaluation of efciency, scale elasticity, and returns to scale is sensitive to stages. In this study, we introduced a procedure … to calculate technical efciency and scale elasticity in a two-stage parallel-series production system. Then, our proposed …

In the nonparametric data envelopment analysis literature, scale elasticity is evaluated in two alternative ways: using … ex-ante price uncertainty in making their production decisions. To address these situations, a scale elasticity … evaluation was performed using a value-based cost efficiency model. However, this alternative value-based scale elasticity …

Schwarze’s article [2003] where ordered logit model was applied to estimate the equivalence scale elasticity. Such model … with other research for Polish data, the method applied here produces higher equivalence scale elasticity. …

, wheat, cotton, barley, and rice are shown to have positive scale elasticity, while sorghum and oats are shown to have …

product of the objective function value with its scale elasticity is equal to the sum of the products of every Lagrange … multiplier with the right-hand side coefficient and the scale elasticity of the corresponding constraint equation. In other words … perfect competition, the cost function of the firm is equal to the sum of the products of every marginal cost, the scale …

In this paper we propose new aggregate or ‘group’ primal and dual scale elasticity measures of an economic system (e … relationship between these new aggregate scale elasticity measures and the individual scale elasticities can be established. The …
