This working paper describes the design of KRAM; a model of the Danish agricultural sector that has been developed in a research project at KVL between 1997 and 2000. The purpose of this paper is to give a general and non-technical overview of the model. The paper is directed at people who want...

In a recent paper Bogetoft and Hougaard (1999) suggest the use of a new potential improvements approach to efficiency evaluation which has the advantage of separating the issue of benchmark selection from the issue of efficiency measurement. In the present paper the potential improvements...

The purpose of this paper is to introduce the concept of worst practice DEA, which aims at identifying worst performers by placing them on the frontier. This is particularly relevant for our application to credit risk evaluation, but this also has general relevance since the worst performers are...

This paper analyses the productive efficiency of 141 public hospitals from 1998 to 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...

The banking industry in Canada is essentially an oligopoly with five large participants controlling about 90% of the market. To evaluate the industry's performance over time, we need to deal with the problem of a small number of DMU's compared to the number of relevant inputs and outputs. To...

DEA-type efficiency studies are often used to investigate levels of efficiencies, differences in those levels between subgroups within a data set and possible determinants of such differences. In the current paper we show how differences in the efficiency patterns between different subgroups...

In this paper we consider staffing decisions in branches of a large Canadian bank. The bank has well-developed staffing models and the branches work in a highly competitive environment. One would therefore expect limited ‘inefficiency’ in the sense of wasted resources and over-staffing....
