The aim of this paper is to show that Marx supports his theory of surplus value by developing a counterfactual argument, that is, by comparing the 'normal' state of a capitalist economy against a hypothetical state in which no surplus is produced. Marx then divides his analysis of value into three successive steps. The first deals with the production of new value in the sphere of production; the second with the process of creation of surplus value, both in the sphere of production and in the sphere of circulation; and the third with the process of equalisation of the rate of profit, which is accomplished via capitalist competition in the sphere of circulation. The paper proposes a formalisation of the three-step analysis and of the counterfactual argument. Marx's three-step analysis is shown to be a scientific analysis of the hidden connections between social relations (expressed in labour flows) and commodity exchange; thus it is not a useless detour. 相似文献

According to the Green Paper presented by the European Commission in July 2001, corporate social responsibility (CSR) is “a concept whereby companies integrate social and environmental concerns in their business operations and in their interaction with their stakeholders on a voluntary basis” (Commission of the European Communities, 2001b, p. 6). On this basis, in 2002, the Italian Government, and especially the Italian Ministry of Welfare, launched an initiative called CSR-SC (social commitment) in order to foster the proactive social role of Italian enterprises, with great attention on SME involvement. The technical partner of the Italian Ministry of Welfare for this initiative is Bocconi University. The goal of this contribution is to present the main results of CSR–SC research project developed by Bocconi University. The paper provides a detailed picture of the general scheme designed to carry out the research project and a review of the different methodologies used to support the solutions proposed. 相似文献

Traditional supply chain models were developed mainly for non-luxury companies and find very little correspondence in the field of luxury, which is considered here as a business super-area including heterogeneous enterprises, belonging to different sectors, which have in common customers characterized by the “need for luxury”. The objective of this paper is to investigate, through a multiple case-study research, peculiar purchasing and supply management practices put in place by luxury firms and to provide a classification of the most recurring approaches. Relevant dimensions (i.e. product complexity and sale volume) to classify luxury firms practices have been used: as a result, four groups of companies have been identified and their purchasing practices described. 相似文献

In this paper, we address the stability issue, stressing the role of labor supply, in a Ramsey model with heterogeneous households subject to borrowing constraints. Making labor supply endogenous leads us to prove the existence of two kinds of steady state: the one where everybody supplies labor, the other where only the most patient agent refrains from working. Going beyond models with inelastic labor supply, we show how preferences of impatient agents affect the saddle-path stability of each type of steady state and the occurrence of endogenous cycles. When their elasticity of intertemporal substitution in consumption exceeds one, instability and cycles are less likely, requiring lower degrees of capital-labor substitution. Conversely, elasticity values below one promote the emergence of fluctuations. We end the paper by showing the existence of the intertemporal equilibrium under market incompleteness, using a local approach based on the first-order conditions. 相似文献

Supply determinants of mining companies have been identified in several factors, with no consensus on their relative importance. These factors, which include mineral commodity prices, the institutional framework, geological characteristics, the scale of mine operations, and specific features of the controlling holdings, can influence the objectives of the mines, and their ability to achieve these objectives. Following a brief overview of alternative literature hypotheses concerned with mineral supply determinants, statistical and econometric analyses are applied to partly pooled cross-mine data over the period 1984–95, for gold and other major export minerals in South Africa. — Des déterminants de l’offre des sociétés minières ont été identifiés dans différents facteurs sans qu’un consensus se dégage quant à leur importance relative. Ces facteurs, au nombre desquels figurent les prix des produits minéraux, le cadre institutionnel, les caractéristiques géographiques, la taille de l’exploitation minière et les caractéristiques de la société de holding majoritaire, peuvent influer sur les objectifs des mines et sur leur aptitude à atteindre ces objectifs. Après une brève revue des hypothèses sous-tendant diverses théories relatives aux déterminants de l’offre des produits minéraux, une analyse statistique et économétrique est effectuée à partir de données partiellement communes, portant sur la période 1984–95, concernant l’or et d’autres importants produits minéraux d’exportation en Afrique du Sud. 相似文献

A number of xenocrystic microdioritic enclaves within the Ross of Mull Granite contain narrow veins of monzonitic material that have formed through the selective partial fusion of granitic magma mechanically incorporated into the microdiorite magma. Field evidence suggests that, as melting of the granitic material ensued, a monzonitic melt formed and exfiltrated from the surrounding microdioritic matrix resulting in Saffman–Taylor instabilities and the development of viscous fingering phenomena. The monzonitic melt network is now preserved as monzonitic veins. Mechanical serial sectioning through a representative veined microdioritic enclave shows that: (a) the topology of the veins is complex but crudely polyhedral, (b) there is porosity (monzonitic melt fraction) variation throughout the length of the veined enclave and (c) that the monzonitic veins are interconnected in three dimensions. Using image analysis software, the total porosity of individual veined enclave sections has been estimated, along with the variation in porosity with depth. Three dimensional rendering and animation software has been used to reconstruct and visualise the monzonitic melt network using Apple QuickTime? software. The above method provides a cheap and powerful way of visualising remnant macroscopic transport properties (such as connectivity and melt topology) in partially molten igneous rocks. 相似文献

Balasko (1978) shows that in a compact subset of the space of economies, not too many economies can have too many equilibria. We extend Balasko’s result to the whole set of economies for a suitable measure. We show that the measure of economies with a large number of equilibria approaches zero as this number tends to infinity. An analogous result in the infinite‐dimensional setting is also established. 相似文献
