Can we meaningfully speak of changes in price under the regime of changes in techniques?

This paper presents a simulation exercise on Sraffa's system under various types of technical changes to show that the direction of changes in prices of commodities is contingent on the choice of the numeraire. Thus, such a comparison of prices in two systems turns out to be meaningless. This result points to the arbitrary nature of the neoclassical supply functions, as they inevitably compare prices across several Sraffa systems on the basis of an arbitrarily chosen numeraire. We anticipated such a result from our reading of Sraffa as part of his 'prelude to a critique of economic theory'

From Cambridge Keynesian to Institutional Economist: The Unnoticed Contributions of Robert Neild

This paper provides a brief sketch of Neild’s life and work. While noting his research in economic policy and peace studies, this essay devotes more attention to his largely-unnoticed contributions to institutional and evolutionary economics since 1984. These are important in their own right, but they are especially notable because Cambridge heterodox economists have been devoted mainly to other approaches, including Marxism and post-Keynesianism. Neild’s distinctive contribution is partly explained by his closeness to both Nicholas Kaldor and Gunnar Myrdal. Myrdal made explicit his adherence to the original American institutionalism: Neild extended that link to Cambridge.Peer reviewedFinal Published versio

The deindustrialisation/tertiarisation hypothesis reconsidered: a subsystem application to the OECD7

The diffusion of outsourcing, both national and international, and vertical FDIs among manufacturing firms, along with the higher integra- tion of business services in manufacturing, has recently led to question the empirical evidence supporting the Deindustrialisation/Tertiarisation (DT) hypothesis. Rather than a \real" phenomenon, it has been argued, DT would be an \apparent" one, mainly due to the reorganization of production across national and sectoral boundaries. The empirical studies that have dealt with the topic so far have not been able to effectively rule out such possibility, because of two main limitations: the sectoral level of the analysis and/or the national focus. In order to overcome them, the paper carries out an appreciative investigation of the actual extent of the DT occurred in the OECD area over the '80s and the '90s by moving from a sector to a subsystem perspective, thus retaining both direct and indirect relations, and by referring to a \pseudo-World" of 7 OECD countries, thus taking into account the \global" dimension of the phenomenon. The results strongly support the DT hypothesis: although the weight of business sector services in the manufacturing subsystem increased, acting as a counterbalancing tendency to the manufacturing decline, subsystem shares significantly decreased, thus confirming DT as a more fundamental trend of modern economies

The Discovery of Comparative Advantage

Torrens [in 1815] clearly preceded Ricardo [in 1817] in publishing a fairly satisfactory formulation of the doctrine [of comparative costs]. It is unquestionable, however that Ricardo is entitled to the credit for first giving due emphasis to the doctrine, for first placing it an appropriate setting, and for obtainin

Outsourcing and structural change: shifting firm and sectoral boundaries

The paper aims at investigating the structural change implications of outsourcing. In trying to bridge the organizational/industrial and the sectoral/structural analysis of outsourcing, it discusses the rational and the methodological pros and cons of a “battery” of outsourcing measurements for structural change analysis. Their functioning is then illustrated through a concise application of them to the OECD area over the ’80s and the early ’90s. A combined used of them emerges as recommendable in checking for the role of outsourcing with respect to that of other structural change determinants

Marx’s metaphysics of human labour in the light of Sraffa : labour theory of value reconsidered

In this chapter, I analyse the foundations of Marx’s analysis of a capitalist economy in terms of labour time to locate the root cause of Marx’s problem of relating values to prices and surplus values to profits, and then show how Sraffa succeeds in solving the problem by liberating Marx from his metaphysics of “human labour.

The Information Economy and the Labor Theory of Value

This article discusses aspects of the labor theory of value in the context of the information industries. First, taking the Temporal Single-System Interpretation (TSSI) of Marx’s labor theory of value as methodology, the paper calculates economic demographics at the level of socially necessary labor time and prices of an example case. Second, the paper questions the assumption that the labor theory of value cannot be applied to the information industries. This paper tests this hypothesis with an analysis of the development of labor productivity in six countries. The paper concludes that the labor theory of value is an important tool for understanding the information economy and the peculiarities of the information commodity
