Abstract(s)
This study develops a framework that combines different management science methods to provide
insights concerning the performance of retailing stores. First, the framework enables to specify
appropriate targets for stores of a retail network using data envelopment analysis. This involves
comparing stores within homogenous groups, that is, supermarkets and hypermarkets. Second, the
framework compares the overall performance of these two groups. This requires the combined use of
a Malmquist-type index and statistical tests. This index is decomposed into sub-indices for comparing
the differences between groups in terms of the efficiency spread in each group of stores and the
productivity differences between the best-practice frontiers spanned by the benchmark stores from
each group. The hypothesis tests are used to verify if the differences between groups captured by the
sub-indices are statistically significant.
