The analysis of the total factors productivity growth in waemu banks: the x efficiency approach

  • Zoma, Isaїe Armand
Registered author(s):

    In this paper, we make an analysis of productivity’s gaps in WAEMU’s banks; the intra-organizational strategy is privileged. For that purpose, we study the progression of the global factors productivity using the Data Envelopment Analysis (DEA), and then the X efficiency scores are calculated using stochastical frontier approach (SFA). The study period (2002 to 2006) corresponds to the post financial liberalization in the zone and to a changed banking and financial environment. We find that the global productivity of the factors remained relatively unchanged but that globally the X efficiency of the banks lightly decreased, remaining nevertheless at a relatively high level of the order of 80% .Big banks, of the viewpoint of their size and the private and semi-public banks, of the viewpoint of their capital structure, have the biggest mean scores of X efficiency.
