Zusammenfassung

SchÄtzungen der SubstitutionselastizitÄt zwischen Importen und heimischen Gütern für die Vereinigten Staaten. - Dieser Aufsatz enthÄlt SchÄtzungen der Importnachfrage- und SubstitutionselastizitÄten für 122 dreistellige SIC-Industrien der USA, wobei jÄhrliche Daten der Periode 1962–1978 und eine Variante der zweistufigen Methode der kleinsten Quadrate benutzt werden. SchÄtzungen aufgrund einer Variante der dreistufigen Methode der kleinsten Quadrate, die simultan für eine Untergruppe dieser Industrien vorgenommen werden, liefern einige Hinweise auf eine Korrelation der Residuen aus den Importfunktionen für die verschiedenen Industriezweige. Obwohl auch sie mit Ungenauigkeiten behaftet sind, bieten die geschÄtzten ElastizitÄten doch einen wertvollen Anhaltspunkt für einzelne Industrien und für die Wahl von Parametern in Computermodellen und anderen Analysen des Au\enhandels mit hoher Disaggregation.

Résumé

Estimations des élasticités de substitution entre des importations et des produits locaux pour les Etats Unis. - Dans cet article les auteurs présentent des estimations des élasticités de demande importatrice et de substitution pour 122 3-digit SIC industries dans les Etats Unis en utilisant des données annuelles pour 1962–1978 et une variante des moindres carrés à deux degrés. Des estimations basées sur une variante des moindres carrés à trois degrés et obtenues simultanément pour un sous-groupe de ces industries révèlent quelque évidence de corrélation entre les perturbances des différentes équations. Bienque soumises à l’imprécision les élasticités estimées donnent un point de repère pour des industries individuelles et pour le choix des paramètres à l’usage en modèles de commerce computables et en autres analyses de commerce extérieur au niveau désagrégé.

Resumen

Estimaciones de las elasticidades de sustitución entre importaciones y bienes nacionales no comerciados para los Estados Unidos. - Este trabajo présenta estimaciones de elasticidades de demanda de importaciones y de sustitución para 122 ramas industriales al nivel de très dígitos de la CIUU para los EEUU, utilizando datos anuales para 1962–1978 y una variante del método de cuadrados mínimos de dos etapas. Estimaciones basades en una variante del método de très etapas, obtenidas para un subgrupo de estas ramas, dieron evidencia de correlacion entre los residuos de las ecuaciones del modelo. A pesar de estar sujetas a imprecisiones, las elasticidades estimadas constituyen un dato Útil para las ramas industriales y para la electión de parámètres para modelos computacionales de comercio internacional y otros análisis del comercio a nivel desagregado.
