Convex output set is common hypothesis in production theory and empirical applications such as the Data Envelopment Analysis. This seems to be taken for granted without any reference to returns to scale. This paper presents the demonstration for joint Cobb-Douglas production frontiers with...

Convex output set is common hypothesis in production theory and empirical applications such as the Data Development Analysis. This seems to be taken for granted without any reference to returns to scale. This paper focuses on the relation between returns to scale and the nature of output...

Convex output set is common hypothesis in both production theory and empirical applications such as the Data Envelopment Analysis. It seems to be taken for granted without any reference to returns to scale. This paper presents simulations for joint Cobb-Douglas production functions. The output...
