A dynamic version of Data Envelopment Analysis (DEA) is developed in the present paper. Our model introduces investment in traditional DEA and imposes intertemporal cost minimization. Adding an intertemporal adjustment constraint into the cost minimization problem, we derive the relation between...

We present a dynamic model of factor demands based on expected discounted costs min-imization. While making only very mild assumptions on expectations and technology, we are able to establish a duality relationship between contemporary factor demands and the technology, and we provide formula...

We present a dynamic model of factor demands based on a contemporary cost function and a dynamic version of Shepard's lemma. While making only very mild assumptions on expectations and technology, we are able to present a complete characterization of the factor demand system and the contemporary...

Nous présentons un modèle dynamique de demande de facteurs de production basé sur un comportement de minimisation de l'espérance des coûts cumulatifs actualisés. Sous des hypothèses peu restrictives sur les anticipations et la technologie, nous établissons une relation de dualité entre...

Using quarterly data for Canada and the Province of Québec, we estimate a complete demand system based on the AIDS model. We present a test of the negative semi-definiteness of the matrix of compensated price effects and of the negative quasi-definiteness of the matrix of uncompensated...

In this paper, we present the results of an analysis of Québec local health care clinics (CLSC) based on a DEA method. Our results confirm previous results based on econometric methods: (1) increasing returns to scale and scope economies imply that average cost could be lowered through...

In the Province of Québec, public colleges depend heavily on public funding: 85% of their budget come from the Department of Education. Those institutions complain that their financial resources are insufficient since Québec government decided to cut their budget in the mid-90. Of course, this...

We survey and synthetize the literature on the measurement of technical progress by the method of Divisia. The approach is first presented under a number of crucial simplifying assumptions. Then we relax those assumptions to allow for non constant returns, the presence of quasi-fix factors of...
