Trademarking activities and total factor productivity: some evidence for British commercial banks using a metafrontier approach (2016)
Journal Article
Duygun, M., Sena, V., & Shaban, M. (2016). Trademarking activities and total factor productivity: some evidence for British commercial banks using a metafrontier approach. Journal of Banking and Finance, 72(Suppl.), Article S70-S80. https://doi.org/10.1016/j.jbankfin.2016.04.017

In this paper, we compute a non-parametric Metafrontier Malmquist index to evaluate the Total Factor Productivity (TFP) change among UK-based trademarking and non-trademarking commercial banks between 2005 and 2013. The use of the metafrontier approa... Read More about Trademarking activities and total factor productivity: some evidence for British commercial banks using a metafrontier approach.

Islamic Banks, Deposit Insurance Reform, and Market Discipline: Evidence from a Natural Framework (2016)

To fill this gap and to verify the conjecture that Islamic bank depositors are indeed able...

Is Ethical Money Sensitive to Past Returns? The Case of Portfolio Constraints and Persistence in Islamic Funds (2015)

This paper presents a novel approach to measure efficiency and productivity decomposition in the banking systems of emerging economies with a special focus on the role of equity capital. We model the requirement to hold levels of a fixed input, i.e.... Read More about How a regulatory capital requirement affects banks’ productivity: an application to emerging economies.

Measuring competition using the Boone relative profit difference indicator (2015)
Journal Article
Duygun, M., Shaban, M., & Weyman-Jones, T. (2015). Measuring competition using the Boone relative profit difference indicator. Economics Letters, 132, 117-120. https://doi.org/10.1016/j.econlet.2015.04.022

This paper suggests a method for implementing the theoretical relative profit difference test for intensity of competition due to Boone (2008). An empirical illustration is given for banking systems in emerging economies.
