• Resumen

  • This paper explores the extent of efficiency improvements achieved by New Zealand banks over the period 1996 to 2002, using data envelopment analysis (DEA), on a time-series, rather than crosssectional basis.

    Evidence is found for improvements in bank efficiency through time, some of which can be attributed to falls in the general level of interest rates, although a further portion may be due to either management effort to improve bank efficiency or technical progress.

    Because some of the results obtained appear to be a consequence of the methodology, rather than necessarily being consistent with other interpretations of the data, the paper also provides insights into complications that can arise with use of DEA.
