Asymmetries in banking conduct: A Cournot - Bertrand model

Author

  • Dalla, Eleni

Abstract

This paper presents a Cournot – Bertrand model with differentiated loans and deposits. In this context, banks compete in different strategic variables, with bank 1 competing in quantities and bank 2 in interest rates. It is shown that loan and deposit differentiation are necessary conditions for a unique Nash equilibrium. The analysis constitutes a simple framework for the introduction of asymmetries in the behavior of oligopolistic banks, providing possible policy and bank ownership extensions.
