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...

We present a dynamic model of factor demands based on expected discounted costs minimization. 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 for...
