It has been submitted that, for the very large number of different traditional formulae to determine price indices associated with a pair of periods, which are joined with the longstanding question of which one to choose, they should all be abandoned. For the method proposed instead, price...

It is submitted, for the very large number of different traditional type formulae to determine price indices associated with a pair of periods, which are joined with the longstanding question of which one to choose, they should all be abandoned. A method is proposed whereby price levels...

Paul A. Samuelson's (1966) capitulation during the so-called Cambridge controversy on the phenomenon of re-switching of techniques in capital theory had implications not only in pointing at a supposed internal contradiction of the marginal theory of production and distribution, but also in...

The index-number problem is typically a problem of aggregation of changes in heterogeneous elements. Mathematically, it consists in reducing the relative change of the elements of a vector into changes in one single numerical value, a scalar. The purpose of this paper is to present a solution of...

This paper proposes to clarify some important questions that are still open in the field of index number theory. The main results are the following: (i) the so-called Quadratic Identity on which the superlative index numbers are based can be applied in more general cases than those traditionally...

The paper presents a first set of results for Spain and Italy using the EUKLEMS database. It emphasizes the different paths followed by the two countries over the last thirty five years, even though they still have many features in common. The motivation behind this paper is the poor...

This paper presents a firm-level analysis of the productivity slowdown that has been recently observed in Italy. DEA techniques are applied to the firm-level data collected within the annual surveys on the economic accounts of enterprises carried out by the Italian National Statistical Institute...
