5. Conclusion
This study started with the aim of estimating a set of comprehensive efficiency performance scores and to identify factors correlated with cost and profit efficiency of Indonesian listed banks over a recent yet studied period. The recent period has seen some uncertainties and pointed reforms in banking sector, which should help garner gains by changing its historically poor efficiency performance. We use all the listed banks in the Indonesian stock exchange: the assets controlled by these banks account for 80 per cent of banking assets. We modelled bank efficiency using both non-parametric and parametric approaches, in addition to using a model to identify two determinants of performance so far unknown about this banking market.
