A NON-SUBSTITUTION THEOREM WITH NON-CONSTANT RETURNS TO SCALE AND EXTERNALITIES

A Non-substitution Theorem with Non-constant Returns to Scale and Externalities

An input-output model with non-constant returns to scale and externalities is presented, and it is shown that in this model, the non-substitution theorem is still valid. More precisely, the quantity side of the theorem, i.e., the proposition on efficiency, remains valid, while there can be no equilibrium prices independent of final demand.

non-corrective approach to pronunciation

the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...

a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

Non-parametric tests of returns to scale

This paper discusses various statistics for testing hypotheses regarding returns to scale in the context of non-parametric models of technical efficiency. In addition, the paper presents bootstrap estimation procedures which yield appropriate critical values for the test statistics. Evidence on the true sizes and power of the various proposed tests is obtained from Monte-Carlo experiments. This...
