Gramsci,Sraffa, Wittgenstein: philosophical linkages

The paper assumes that since Gramsci influenced Sraffa and SraffA influenced Wittgenstein it may be possible to delineate a set of philosophical ideas which they shared in some degree. Gramsci's ideas are first reviewed on terms of his concept of hegemony, concept of caesarism and philosophy of praxis. On this basis three philosophical themes are identified in his thinking: the conept of emergence; catastrophic equilibrium; and the idea of a concrete universal. The thinking of Sraffa (both earlier and later) and the thinking of Wittgenstein (later) are then interpreted in terms of these same three themes. These links neither exhaust their philosophical thinking nor necessarily constitute the only links among the three. But these ideas provide one way of exploring connections among the three. The paper closes with brief remarks concerning two opposed philosophical traditions in modern European intellectual history at the turn of the century — one associated with thinking in Britain and one associated with continental thinking — meant to suggest the distinctiveness of a line of thinking running through Gramsci, Sraffa and Wittgenstein.     

Concurrent trading in two experimental markets with demand interdependence

Summary. We report results from fifteen computerized double auctions with concurrent trading of two commodities. In contrast to prior experimental markets, buyers' demands are induced via CES earnings functions defined over the two traded goods, with a fiat money expenditure constraint. Sellers receive independent marginal cost arrays for each commodity. Parameters for buyers' earnings functions and sellers' costs are set to yield a stable, competitive equilibrium. In spite of the complexity introduced by the demand interdependence, the competitive model is a good predictor of market outcomes, although prices tend to be above (below) the competitive prediction in the low-price (high-price) market.     

Sraffa,Okun, and the theory of the imperfectly competitive firm

Piero Sraffa's Production of Commodities by Means of Commodities is wedded to Arthur Okun's Prices and Quantities to bring out important implications for the theory of the imperfectly competitive firm. The implications relate to firm objectives and to firm behavior in both the ‘vertical’ environment (relations with suppliers) and the ‘horizontal’ environment (relations with customers and competitors).     

Sraffa and the Marshallian tradition*

Abstract

The paper retraces some of the stages in Sraffa's thinking about the work of Marshall, by drawing on unpublished material in the Sraffa archive from 1923 to 1930. It argues that Sraffa transformed his dissent – which was based on ideological grounds – into a ‘quest for the fatal error’ to demolish the logical construction of Marshallian theory. Some of his attacks were successful (for example, the critique of the relation between costs and output); other attempts failed (the critique of the ‘normal rate of profit’ and the critique of the concept of marginal productivity) since Sraffa could not find enough textual evidence to support his position.     

Sraffa and von Neumann

This paper discusses the relationship between Piero Sraffa's 1960 book and John von Neumann's 1937 paper on economic growth in the light of some of the material contained in Sraffa's unpublished papers and correspondence. It is argued that the two contributions share a similar outlook and exhibit conceptual parallels; in fact, they can both be said to belong to the 'classical' approach to the theory of value and distribution. The latter is characterized, among other things, by an asymmetric treatment of the distributive variables, the rate of return on capital and the real wage rate. Sraffa's papers show that when he came across the von Neumann model in the mid-1940s his own analysis was already quite advanced, including his analysis of joint production. The paper also contains an exchange of letters between John Richard Hicks and Sraffa on some of the issues dealt with in the latter's book.     

Marx and Sraffa: A Comment on Gehrke and Kurz

This comment focuses on the assertion by Gehrke and Kurz (2018) that the origin of the equations which formed the backbone of Sraffa’s Production of Commodities by Means of Commodities is not related in any way to Marx, and particularly Marx’s reproduction schemes, as argued by the late Giorgio Gilibert and myself. This comment argues that the 2018 article by Gehrke and Kurz makes significant—but unacknowledged—retreats from positions previously presented by the authors, and that the relevance of Marx and his reproduction schemes for the origin of Sraffa’s (1960) work for Production of Commodities is beyond reasonable doubt.     

Sraffa,Keynes and 'The Years of High Theory'

This paper argues that Shackle's interpretation of 'the years of high theory' is flawed. Shackle (1967) sees Sraffa's critique of the Marshallian theory of value only as a step in the development of the theory of imperfect competition. In the same vein, Shackle reduces the message of Keynes's General Theory to the claim that unemployment results from the existence of uncertainty and irrational expectations. Thus, Shackle leaves open the possibility that both Sraffa's critique of Marshall and Keynes's theory of effective demand do not question the internal coherence of neoclassical theory, but instead merely assert that market imperfections render it irrelevant for the analysis of the real world. This paper argues, in contrast, that the theories of Sraffa and Keynes should be interpreted as radical departures from marginalism, and represent a return to the surplus approach of classical political economy.     

Marx,Sraffa, and Surplus: Observations Prompted by Garegnani (2018)

ABSTRACT

In a posthumously published article, Pierangelo Garegnani (2018. ‘On the Labour Theory of Value in Marx and in the Marxist Tradition.’) depicts Marx’s project in Capital as that of ‘developing systematically the theory of Ricardo and [the] implications of social conflict’ implied by Ricardo’s ‘surplus approach to value and distribution’. This paper argues to the contrary that Marx’s theory of surplus value and exploitation differs from (neo-)Ricardian surplus theory in fundamental ways, and modifies Garegnani’s simple Sraffian model to illustrate the distinctive implications of Marx’s theory.     

Sraffa on Fixed Capital,Money and the Phases of Capitalism

In this paper I address some elements in Piero Sraffa's thinking that are connected to his conceptualization of the phases of capitalism. Sraffa describes various stages of capitalism using similar categories to the ones employed in the model of the economy provided in Production of Commodities. This is done by distinguishing the role of population, land and (circulating, intermediate and fixed) capital in each stage. Sraffa changed his conceptualization of fixed capital over the years, until he reached its final formulation. The conceptualizations of fixed capital that Sraffa discusses, together with his remarks on money which are made through an analogy with circulating and fixed capital, provide some elements that shed light on Sraffa's view of the dynamics of capitalism.     

Sraffa in historiographical perspective: a provisional statement

The paper explores the theory of the aggregate price, profit, and business fluctuations in Keyne's Treatise for its implications for modern macro-economic analysis. As in the Treatise, profits are first defined within a theory of the agregate price level, as aggregate investment minus saving. Deriving aggregate total revenue and aggregate total cost from this price theory, the paper shows how to construct a version of the Keynesian cross diagram. The cross construction suggests an important qualification for fiscal policy, that total cost does not shift. Then, using a neoclassical definition of profit and the total-cost / total-revenue approach, the paper derives aggregate supply, and then adds aggregate demand in an integrated framework. Comparative statics of the AS-AD analysis and the central role of profit in the Treatise suggest that a focus on profit might be useful in identifying exogenous technology shocks of real business cycle theory.     

Sraffa numeraire and reswitching: A note A note

The paper demonstrates that changing the numeraire from Hicks' to Sraffa's does not affect the location and, a fortiori, the number of switch points between two given techniques. This negates some recent claims to the contrary, and supports the earlier general position that the choice of numeraire has no bearing on reswitching, even though it does have a bearing on capital reversal. In the process the paper shows that the rate of growth of the economy and the marginal propensity to save also do not affect the switch points, which may thus be regarded as depending essentially on technical factors alone.     

Money,barter, and consumption interdependence

By introducing a degree of consumption interdependence into a search model, we show that people may switch from using money to bartering during hyperinflation, but barter activities, however, could still be popular even though the inflation rate is low.     

Sraffa,Myrdal, and the 1961 Söderström Gold Medal

In this paper, we give an account of the awarding of the 1961 Söderström Gold Medal to Piero Sraffa by the Royal Swedish Academy of Sciences (Kungliga Vetenskapsakademien). We highlight the central role that Gunnar Myrdal played in the allocation of this prize to Sraffa and the amicable relationship between these two economists, as well as their views on Ricardian economics. In addition, we provide details of Sraffa's activities in Stockholm, including his attendance at the award ceremony. In our final remarks, we reflect on the significance of the 1961 Söderström Gold Medal for the history of economics as a field of study.
