The apparent trade-off between functional flexibility and functional properness has been identified for the case of the quadratic cost function. Using the quadratic cost function, the proposed ...

For this, a normalized quadratic cost function was estimated. The results show important productivity gains with both technical change and scale effect playing important roles. The Journal of ...
