The paper develops a simultaneous equations stochastic frontier model (SFM) with dependent random noise and inefficiency components of individual equations as well as allowing dependence across all equations of the model using copula functions. First. feasibility of our developed model was verified via two simulation studies. Then the model was applied to assess cost efficiency and ma... https://www.ealisboa.com/top-save-RE-DESIGNED-Strikketoy-oppbevaring-Prosjekt-27-Sort-100-Skinn-great-save/
