In this paper we employ branch space, physical capital and personnel score as inputs for producing total deposits and total loans in the first stage as intermediate measures and in the second stage total loans and deposits used to produce net profit. In order to have more conformances to the reality, loan losses as an undesirable output entered into the model in the second stage.
