چکیده	This paper investigates, using a multi-product paradigm, the market structure of the Iranian banking sector to evaluate the role of scale. In so doing, we checked for economies of scope by multi-product cost function as well as the impact of potential economies on the banking sector structure including 18 banks during the period 2008–2014. The changes in Panzar-Rosse H-Statistic as a result of the variety in products reflect changes in the monopolistic power. The results show that an increase in the variety of offered products increases banks’ monopolistic power.
