Two stages DEA models are used in many fields of management and industry. One of the concepts that has attracted the attention of researchers in the theory of production is the concept of ranking the units with a two-stage network. A unit ranking can provide useful information to decision makers (DMUs) about optimal decision making activities. This concept defines the superiority of a unit in t...

The study presents an empirical analysis of best practice production and cost frontiers for a sample of 94 acute care hospitals by applying Data Envelopment Analysis (DEA) and a regression model, in a two-stage approach. This paper contributes to the DEA and efficiency measurement literatures by adding results from a homogeneous method of partitioning cost efficiency into its allocative (or pri...

Efficiency measurement is an important issue for any firm or organization. Efficiency measurement allows organizations to compare their performance with their competitors’ and then develop corresponding plans to improve performance. Various efficiency measurement tools, such as conventional statistical methods and non-parametric methods, have been successfully developed in the literature. Among...

Based on a two-stage analysis of a panel of data on 12 outlets of a high-end retailer for 24 months, we investigate how the level of supervisory monitoring affects retail sales productivity. In the first stage, we use Data Envelopment Analysis (DEA) to compute the relative productivity of retail outlets in using their labor and capital resources to generate store sales. In the second stage, we ...

Understanding the effects of operational conditions and practices on productive efficiency can provide valuable economic and managerial insights. The conventional approach is to use a twostage method where the efficiency estimates are regressed on contextual variables representing the operational conditions. The main problem of the two-stage approach is that it ignores the correlations between ...

The increasing use of information technology (IT) has resulted in a need for evaluating the productivity impacts of IT. The contemporary IT evaluation approach has focused on return on investment and return on management. IT investment has impacts on different stages of business operations. For example, in the banking industry, IT plays a key role in effectively generating (i) funds from the cu...

Mon stage de DEA, dont le mmmoire est ici prrsentt, s'est situu dans le cadre d'une collaboration entre le LSV (ENS Cachan) et l'IRCyN (Ecole Centrale de Nantes). J'ai tt, durant ce stage qui s'est ddroull pour un tiers du temps Nantes et pour deux tiers Cachan, co-encadrr par Alain Finkel (LSV) et Olivier Roux (IRCyN).

We incorporate the concept of fairness in a conventional two-stage process to inquire how fairness may affect overall and individual stage efficiency. The relations among the non-cooperative, cooperative and standard DEA approaches are investigated when two sub-units are concerned about fairness. An empirical example is shown to verify the approach.
