The recent nancial crisis highlighted how banks' funding and investment portfolios are associated with their risk taking. In a "normal" DEA banking efficiency model this risk element, embedded in banks' business models, is indicated by possibly inappropriate mixes of funding portfolio and/or...

In this paper we examine the possibility of using the standard Kruskal-Wallis rank test in order to evaluate whether the distribution of efficiency scores resulting from Data Envelopment Analysis (DEA) is independent of the input (or output) mix. Recently, a general data generating process (DGP)...

This paper analyses the productive efficiency of 141 public hospitals from 1998-2004 in two Canadian provinces; one a small province with a few small cities and a generally more rural population and the other a large province that is more urban in nature, with a population who mainly live in...

This paper proposes a test for whether data are over-represented in a given production zone, i.e. a subset of a production possibility set which has been estimated using the non-parametric Data Envelopment Analysis (DEA) approach. A binomial test is used that relates the number of observations...

In this paper we introduce a new Malmquist productivity index that has three attractive features: it avoids linear programming infeasibilities under variable returns to scale, it allows for technical regress, and it does not need to be recomputed when a new time period is added to the data set....

This paper expands the banking efficiency literature by developing a banking intermediation model that captures both profit-maximising and corporate social responsibilities (CSRs) of banks. Using a dataset of 21 banks for each year 2006 to 2008, we evaluate the relative efficiency of Ghanaian...
