Homogeneity masquerading as variety: the case of horizontal innovation models

The literature on ‘horizontal innovation’ claimsto analyse cases where unbounded endogenous growth comes froman increasing variety of intermediate goods. The present papercontends that a good sample of representative models in thisliterature share two essential assumptions regarding productiontechnology, and that these assumptions together amount to assumingthe homogeneity of various intermediate goods. In these models,there is no variety of intermediate goods to increase owingto R&D activities; what increases is a mass of a singlehomogeneous intermediate good.     

Finance and the Cambridge Equation: A Comment

Marx recognized two distinct but also interrelated processes of increasing surplus-value extraction: absolute and relative surplus-value. Both these processes hinge upon the duration, the intensity and the productivity of labour, albeit in different ways. The increase of the duration of labour is indisputably related to absolute surplus-value and the increase of labour productivity to relative surplus-value. However, there is controversy regarding the position of the intensity of labour. Marx's argument that it belongs to relative surplus-value is disputed by many Marxists. This paper argues that Marx's thesis is correct because the intensification of labour and the increase of its duration are ultimately two opposing trends and thus should not be coupled in the same concept.     

Normal Values and Average Values

This essay discusses the implications of the idea that the Keynesian premise implies deviations between the normal and the average degrees of utilization. A system of equations called the ``average system'' is proposed for the study of average values, as distinct from normal values, by way of a hypothetical steady- state growth path for each sector. A long-period implication of the short-period under-utilization of productive capacity is presented in terms of a two-sector model.     

The financial system and the Pasinetti theorem

Palley (Inside debt, aggregate demand, and the Cambridge theoryof distribution, Cambridge Journal of Economics, vol. 20, no.4, 465–74, 1996; Financial institutions and the Cambridgetheory of distribution, Cambridge Journal of Economics, vol.26, no. 2, 275–7, 2002) considers the Pasinetti theoremin the context of the credit money system where banks generatedebts endogenously, and claims that the theorem ceases to holdin such a system, being valid only in the loanable funds system.This paper traces the root of Palley's claim to his assumptionregarding the ownership of banks, sets out an alternative (morerealistic) ownership arrangement, and thereby restores the Pasinettitheorem unscathed in the credit money system (at least in thekind Palley must have considered). The paper, however, uncoversthe case where the theorem indeed collapses and discusses thereason for it: the hoarding of a non-interest-bearing asset.
