Open call for the formation of

This is an open invitation to researchers active in measurement, modelling and analysis of performance in economics and management to join the GAPEM research group. Rooted in frontier analysis and economics, it will pursue an interdisciplinary quest to fully address open challenges in methodology and application.

Performance in Economics and Management: The Quest for Consolidation

The notion of performance has a long and controversial history in economics and management as well as in their respective sub-disciplines. For example, the evaluation of the performance of financial markets often makes use of different concepts and methodological tools from the ones adopted by the accountant when evaluating the performance of a service organisation. Divergences in definitions and operational procedures are therefore still widespread.

Performance benchmarking using frontier analysis, either non-parametric analysis (often known as Data Envelopment Analysis models), or parametric stochastic frontier analysis, has reached a certain maturity after a strong development in the last twenty years. Detailed accounts on its conception in the 1950s, path breaking papers and the chronology of events that enabled this surge are given in e.g. Seiford (1996) and Lovell (2000). These frontier-based notions of performance have proven successful from both a theoretical and an empirical point of view in the economics literature as well as in the management and operations research literatures.

The very success of these frontier-based performance notions provides a unique opportunity to bring together researchers from various disciplines in an interdisciplinary quest on the foundations of performance. While this development in itself is unlikely to eradicate existing differences in performance definitions, we hope that the creation of a common ground for discussing performance may sharpen the current conceptions of participants and to create an environment fostering theoretical and empirical collaborations in this area, most broadly defined.

The Need for A Regional Group

Labelled one of the “success stories of operations research”, researchers in frontier analysis are now organized in the Productivity Analysis Research Network (PARN) or the EuroDEAPM working group, in addition to working groups with INFORMS and other organizations. So, why is there a need for yet another group of performance analysts?

There are a number of scattered research environments in Continental Europe (in particular in Belgium, France, and the Netherlands) with strong attachments to the theoretical and applied fields that could be promising enablers in the next wave of frontier research. However, it is the general feeling that currently no natural focal point exists to enhance collaborations between these individuals and groups of researchers. This proposal is an open invitation to these environments to join in a regional group that intends to cater for the needs of people broadly situated within Belgium, the North of France, and the Netherlands. Its main ambition is to offer a forum for exciting intellectual discourse on the broader base of efficiency analysis in theory and application. The “Group for Analysis of Performance in Economics and Management” (GAPEM) does not intend to duplicate arrangements and initiatives that are well established, but to unify and vitalize a potentially fruitful collaboration in an inter-disciplinary field within a rather well defined geographical region.

Open Research Challenges: A Few Examples

In spite of its rich literature and widespread empirical exposure, there are still a number of unresolved and challenging issues left to address in the field. Many of these seem to be situated at the interface between economics and management. For instance, there still seems a wide scope for frontier applications and extensions in marketing, human resource management, and finance. This probably just requires putting the right people originating from several disciplines together. While many institutions pay lip service to interdisciplinary work, few small-scale initiatives really try to bring people together from different fields in an effort to catalyse research. GAPEM sees it as one of its tasks to do exactly that.

While such “extra-ordinary” interdisciplinary science may be much harder to realize that just filling up loopholes within an existing field, there is still ample scope for intradisciplinary work to contribute to the objectives of the group. Just limiting ourselves to the economic field, which we happen to know best, at least two major issues concern the economics of production and the activity analysis.

First, performance evaluation models under various specifications are widely applied to economic activities where the evaluation task, the preference structure and the microeconomic context are ignored, postulated or, at best, sketched. Although considerable thought has been devoted to the structural characterization and representation of frontier models, the body of integrative work is still modest. The evaluation may be undertaken in a static or dynamic setting, ex post to determine or inform on the determination of ex ante budgets, targets, revenues and/or explicit or implicit incentive systems. In itself, this evaluation in combination with assumptions on the discretion and behaviour of the evaluated units gives rise to a number of relevant questions related to the design, implementation and dynamics of efficiency measurement systems. One of the strengths of the non-parametric approach in evaluation of multi-output multi-input technologies is its ability to accommodate a family of preference functions. However, apart from dual neo-classical formulations, this dimension has rarely been rigorously pursued. Already addressed by the multicriteria modellers, this field also opens up for possibilities of theoretical and applied work in fields such as experimental game theory, economic psychology, educational psychology and sociology. Further, the decision-making unit (DMU), the preferences of the operator and the evaluator are all defined in a microeconomic context; a firm, a market or an industry. Industrial organization has a well-established tradition to address and analyse this context to derive results of descriptive or normative character. All too often, empirical work in frontier analysis is detached from this body of literature, failing to fully explore the challenges of the data to trigger the excitement of academics and practitioners alike.

Second, especially non-parametric analysis draws on a heritage from operations research that involves a certain pragmatism in the model formulation. Albeit reasonable in some context of highly experienced modellers, it is surprising not to find more work on the fundamentals of activity analysis to systematize the modelling for practitioners. Even elementary decisions such as the selection and specification of variables and technology are left at the discretion of the modeller. Our belief is that consolidating work on these issues will inspire and anchor both methodological and applied research. Certainly, the much acknowledged but yet unresolved issue of treatment of data uncertainty in non-parametric method, as well as the less addressed structural choice in parametric analysis, could benefit from revisiting the roots of activity analysis. Other important challenges that await operations researchers are related to consistent aggregation-disaggregation metrics in time and space, stability and dominance metrics and modelling of decentralized decision making under anticipation of DEA control.

It goes without saying that both of these research questions in themselves could fill an individual career. Hence, we would hope a few people would be interested to share part of what could become an exciting venture.

Activities

Rather than over subscribing and under delivering, we purport to a realistic, yet critical activity level. In particular we foresee GAPEM activities on three levels.

1. Seminars
Within the network of participating research groups and universities, we will organize bimonthly seminars on the topics of interest, inviting all members. The seminars may consist of invited speakers, local group members, or workshops by doctoral students.

2. Regional Level Activities
GAPEM has arranged a website that will be located at IFRESI or IAG. It serves to disseminate information on scientific activities in various sub-domains of frontier research. The site will also furnish a bibliography as well as vitae and contact information on affiliated members.
A refereed discussion papers series, which may be a subset of the discussion papers issued at member’s institutions, will also be disseminated on the website, along with the possibility to subscribe to a regular newsletter for the group’s activities (in a later stage).
GAPEM intends to organize two annual workshops (in April and October, say) in a member university to gather all members. Both theoretical and applied presentations are encouraged and a rotating schedule ensures proper coverage of themes in the group.

3. International Level Activities
GAPEM will encourage and support international collaboration through IFRESI, open for participating group members and institutions. The working languages are English and French, where English is recommended for written communication and publications.
Naturally, GAPEM will be actively participating in the international conferences such as EWEPA (European Workshop on Efficiency and Productivity Analysis) and NAPW (North American Productivity Analysis Workshop). Moreover, the group could potentially be a candidate organizer for an upcoming EWEPA workshop.

Organization: A Lean Structure to Serve All

GAPEM will have an administrative centre (IFRESI located at Lille) and several research locations supporting the group (the first centre to join is IAG located at Université Catholique de Louvain)
GAPEM is suggested to be administratively run by an Executive Committee consisting of an elected president and two directors in charge of research and administration. The members of this Committee serve a three-year mandate and will be located physically at one of the initial group centres (IFRESI and IAG). Committee members serve 3-year mandates to ensure a good representation of the participating bodies. The Executive Committee handles the operative decisions on behalf of the group and coordinates information and meetings.
Without spelling out all details, the charter of the group (in attachment or on website) is aimed at promoting a representative and flexible governance: it is ultimately focused at facilitating scientific discourse and collaboration.
