Long-Term Productivity and Factor Demand in the Canadian Pulp and Paper Industry

摘要: The long-term structure of production, factor demand and productivity in the Canadian pulp paper industry was studied for period 1956 to 1982. A four input (labor, capital, material energy) nonhomothetic translog cost function used purpose. Least-cost combinations factors were obtained by imbedding an interrelated dynamic adjustment process. These least-cost paths, from which cyclical fluctuations due business turns filtered out, then derive each input. Long-term elasticities substitution also computed. short-term results compared. Important findings study were: (i) production can be represented nomothetic version function, (ii) technological progress is slow despite evidence some economies scale (iii) all are long-run substitutes short-run complementarities between (iv) observed misallocated during as compared allocations, (v) growth labor energy declined seventies early eighties, sixties, but their productivities did not, (vi) though both raw rate decline lower on path, (vii) price increases after 1971 could have been than what actually experienced if change with economic circumstances more rapidly. La a long terme de facteur demande et productivite dans l'industrie canadienne putpe papier est etudiee pour la periode Une fonction cout “nonhomothetic translog” avec quatre entrees (la main-d'oeuvre, le materiel l‘energie) utilisee cette etude. Les combinaisons les moins cheres des facteurs sont obtenues en incluant un ajustement dynamique du processus d'interaction. Ces chemins chers, desquels conjoncturelles dues aux changements d'affaires enlevees, utilises deriver chaque entree. elasticites aussi calculees. resultats ceux court compares. decouvertes importantes etude sont: l’-industrie peut etre representee par “homothetic” “translog,” progres technologique lent malgre l‘evidence certaines grande echelle, tous substituts complementarites parmi entree etait allouee au mauvais endroit pendant d’etude comparaison allocations cheres, croissance observee main-d'oeuvre d‘energie diminue annees soixante-dix debut quatre-vingts, soixante, mais leurs productivites n'a pas diminue, bien que observees matieres premieres ont taux diminution plus bas sur chemin terme, augmentations prix pulpe apres auraient pu qu'on experimente si capable changer rapidement selon circonstances economiques.
