We consider economic obstacles that limit the reliability and accuracy of value-at-risk (VaR). Investors who manage large market transactions should take into account the impact of the randomness of large trade volumes on predictions of price probability and VaR assessments. We introduce...

The difficulties of the classical and Marxian labour theory of value are overcome when labour is measured in terms of marginal labour value. Marginal labour value is the inverse of the marginal productivity of labour. Relative prices are equal to the ratio of marginal labour values. This article...

I have designed a valuation method adjusted to the specific characteristics of Spanish professional soccer clubs under the hypothesis that clubs behave financially reasonably. I analyse the factors that define the context where soccer business takes place. I have built a conceptual model that...

We consider a model of production with a continuum of linear techniques and examine the related choice of technique and shape of the demand for capital schedule. The primary conclusion regards the possibility of a decreasing demand for capital schedule combined with reswitching and reverse...

This paper deals with the notion of residual income, which may be defined as the surplus profit that residues after a capital charge (opportunity cost) has been covered. While the origins of the notion trace back to the 19th century, in-depth theoretical investigations and widespread real-life...

This paper estimates the value of superstitions by studying the auctions of vehicle license plates. We show that the value of superstitions is economically significant, which in turn justifies their persistence in human civilization. We also show that such a value, though based inherently on...

This paper presents a new way of measuring residual income, originally introduced by Magni (2000a, 2000b, 2003). Contrary to the standard residual income, the capital charge is equal to the capital lost by investors. The lost capital may be viewed as (a) the foregone capital, (b) the capital...

In the literature on firm strategy and product differentiation, consumer price-quality trade-offs are sometimes represented using consumer “value maps”. These involve the geometric representation of indifferent price and quality combinations as points along curves that are concave to the...

The modern reformulation of Classical analysis of value and distribution built upon Sraffa’s Production of Commodities provides quite a general and open framework to study distributive relationships, that deserves to be still explored. The present work aims to go through these relationships...

Sraffa (1960) introduced a classification of goods which has been used without modification for a long time. According to him goods have to be classified as basic and non-basic commodities. Among non-basic commodities, he extracts goods which are used directly and indirectly in the production of...
