An Analysis of Productivity Changes in the Iranian banking Industry: a Bootstrapped Malmquist Approach




Type Of Work


  • Scholarly edition

Abstract


  • This study employs various bootstrapped Malmquist indices and efficiency scores to investigate the effects of government regulation on the performance of the Iranian banking industry over the period 2003-2008. An alternative decomposition of the Malmquist index, introduced by Simar and Wilson (1998a), is also applied to decompose technical changes

    further into pure technical change and changes in scale efficiency. A combination of these approaches facilitates a robust and comprehensive analysis of Iranian banking industry performance. While this approach is more appropriate than the traditional Malmquist approach, for the case of banking efficiency studies, it has not previously been conducted for

    any developing country’s banking system. The results obtained show that although, in general, the regulatory changes had different effects on individual banks, the efficiency and productivity of the overall industry declined after regulation. We also find that productivity had positive growth before regulation mainly due to improvements in pure technology, and

    that government ownership had an adverse impact on the efficiency level of state-owned banks. The bootstrap approach demonstrates that the majority of estimates obtained in this study are statistically significant.
