Nonparametric estimation of returns to scale: method and application

The paper describes a method of estimating variable returns to scale in production that adaptively fits spline functions, using model selection criteria, to determine the appropriate number and location of break points for a fixed factor of production. Unlike other approaches, the method obtains non...

description The paper describes a method of estimating variable returns to scale in production that adaptively fits spline functions, using model selection criteria, to determine the appropriate number and location of break points for a fixed factor of production. Unlike other approaches, the method obtains nonparametric estimates of variable returns to scale for small samples while ensuring global curvature and flexibility properties are maintained. An application of the method is presented using data from the British Columbia sablefish fishery. Les auteurs décrivent une méthode d'estimation des variations de rentabilité en fonction de l'échelle de production susceptibles de s'ajuster è des fonctions spline, utilisant des critéres modèles de sélection pour déterminer le nombre et la situation des seuils de rentabilité pour unfacteur de production fixe. À la différence d‘autres avenues d‘analyse, la méthode permet d‘obtenir des valeurs non paramétriques de la rémunération variable selon l'échelle, è partir de petits échantillons, tout en garantissant le maintien de la courbure générale et de la souplesse d'application. Les auteurs proposent une application de la methode, utilisant les données des pêches de morue charbonnière en Colombie‐Britannique.
