Abstract

[eng] Distribution of work in grain producing farms : a Tobit model of semi-fixed labour, . by Dominique Vermersch.. . Conventional models derived from duality theory assume that labour is either a fixed factor or a variable one. In this paper, we examine a more realistic model which uses the Tobit approach. Labour is assumed to be semi-fixed : it is free to vary for some observations and it is fixed for the others. The fast part is devoted to the estimation of this model using a cross-section of farms. [spa] La asignación del trabajo en las explotaciones cerealistas : una modelización Tobit de una demanda de factor semi fijo, . por Dominique Vermersch.. . Inscribiéndose en un esquema dual clásico en la teoría de la producción, la justificación teórica de una modelización Tobit permite tomar en cuenta el carácter casi fijo de ciertos factores, en la medida en que éste es efectivo para ciertas observaciones solamente. Aplicado a una muestra de explotaciones cerealistas, el modelo microeconométrico asociado contribuye a la medición de una oferta latente de trabajo y caracteriza la tecnología agrícola utilizada cuando el factor no es fijo. [fre] L'allocation du travail dans les exploitations céréalières : une modélisation Tobit d'une demande de facteur semi-fixe, . par Dominique Vermersch.. . Dans la filiation d'un schéma dual classique en théorie de la production, la justification théorique d'une modélisation Tobit permet de prendre en compte la semi-fixité de certains facteurs, dans la mesure où celle-ci est effective pour certaines observations seulement. Appliqué à un échantillon d'exploitations céréalières, le modèle microéconométrique associé contribue à mesurer une offre latente de travail et caractérise la technologie agricole utilisée en l'absence de fixité. [ger] Die Arbeitszuordnung in Getreidebaubetrieben : eine Tobit-Modellierung einer Nachfrage nach halbfixen Faktoren, . von Dominique Vermersch.. . Unter Zugrundelegung eines klassischen, dualen, produktionstheoretischen Schemas erlaubt die theoretische Rechtfertigung einer Tobit-Modellierung dem halbfixen Charakter gewisser Faktoren insoweit Rechnung zu tragen, als dieser nur für gewisse Beobachtungen tatsächlich gegeben ist. Das auf eine Auswahl von Getreidebaubetrieben angewandte mikroökonomische Modell trägt dazu bei, ein latentes Arbeitsangebot zu messen, und kennzeichnet die Landwirtschaftstechnologie bei Nichtvorliegen fixer Merkmale.
