Foreword to the Symposium

This paper investigates a number of aspects of Piero Sraffa's early philosophical thinking by placing him within the historical materialist tradition of reasoning about the relation of ideas to the historical process. It first distinguishes Alfred Marshall's views about the historical development of ideas by addressing Marshall's responses to the criticisms of William Cunningham of the English Historical School. Marshall's concept of economics as a universal engine of discovery was rejected by Sraffa in his early writings. Sraffa's critique of Marshall is then argued to lead to two early philosophical commitments on Sraffa's part: that deductivist modes of explanation are inappropriate in economics and that economics aims to explain the underlying structures of causal interaction that had been the concern of the classical political economists. The paper closes with brief remarks on how Sraffa's later philosophical thinking might be approached.     

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book and John von Neumann's 1937 paper on economic growth in the light of some of the material contained in Sraffa's unpublished papers and correspondence.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.     

On the importance of institutions and forms of organisation in Piero Sraffa's economics: the case of business cycles,money, and economic policy

Abstract

This paper is based on an investigation of the Sraffa Archives and tries to characterise Piero Sraffa's approach to business cycles and economic policy. It includes two parts. The first part of the paper shows the importance of economic institutions and social conventions in Sraffa's contribution to economics and their relation with social conflicts. The second part of the paper shows how this importance permits to understand better business cycles and economic policy but also indirectly contributes to a re-interpretation of Sraffa's contribution to economics.     

Keynes and Sraffa's 'Difficulties with J. H. Hollander'

The paper reports on Jacob H. Hollander's cooperation with John Maynard Keynes and Piero Sraffa in the preparation of the latter's edition of The Works and Correspondence of David Ricardo. The report is based on archive material from various sources, including the unpublished papers of Edwin Cannan, Piero Sraffa, Jacob H. Hollander, John Maynard Keynes, and Jacob Viner, and the archive of the Royal Economic Society. The archive material consulted by us shows that, put mildly, Jacob H. Hollander did not promote Sraffa's editorial project: he held back material which he had received from Frank Ricardo and did not disclose to Sraffa that he owned several important letters which he had privately purchased. Moreover, Sraffa was refused access to Ricardiana even after he had traced them down in laborious detective work to be in Hollander's possession. Hollander's unwillingness to cooperate with Sraffa considerably delayed the publication of the Ricardo edition.     

Method and analysis in Piero Sraffa's 1925 critique of Marshallian economics

This paper provides an analysis of the logical structure and analytical content of Piero Sraffa's 1925 Italian paper, ‘Sulle relazioni fra costo e quantità prodotta’. It shows that Sraffa's criticism of the supply side of Marshall's theory of value in a competitive partial equilibrium model involves analytical and methodological issues. Endorsing an agressive methodology Sraffa logically reconstructs Marshall's model on variable returns to determine its empirical domain. He demonstrates that the latter encompasses only the empirically irrelevant cases of specific factor industries and specific external economies industries and that it cannot be generalized to non-specific factor industries and to non-specific external economies industries.     

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.     

A Note of Thanks

This paper examines the early years of Piero Sraffa's career. Its purpose is to present

new information that may improve our undersranding of his life and work and to integrate or rectify what is already contained in the biographical essays published during the fast two decades with new data emerging from his personal papers at the Wren Library of Trinity College and from other—often related—sources.     

Pigou,Del Vecchio,and Sraffa: the 1955 International “Antonio Feltrinelli” Prize for the Economic and Social Sciences

In 1955, the Accademia Nazionale dei Lincei awarded the inaugural International “Feltrinelli” Prize for the Economic and Social Sciences to Arthur Cecil Pigou. This paper considers Gustavo Del Vecchio's active role on the selection committee in recommending Pigou for the Feltrinelli Prize and the related correspondence between Pigou, Piero Sraffa, and Del Vecchio. One of the most significant discovery reported in this paper is Sraffa's contention, expressed in an unpublished letter to Del Vecchio, that Pigou had “never been honoured in proportion to his merits.”     

Reading Sraffa's Indices – a note *

Piero Sraffa took thirteen years to publish the General Indexto The Works and Correspondence of David Ricardo.The Index is compared to others and is shown to be exceptional in that it leads the way to specific interpretations of Ricardo's life and theory. The choice of entries referring to theory is based on Ricardo's own concepts and carefully avoids neoricardian, Marxian and neoclassical terms. Examples discussed concern ‘comparative advantage’ and ‘value’ The entries referring to Ricardo's life are proof of Sraffa's broad historical interests and focus on certain characteristics of Ricardo.     

Joan Robinson and the three cambridge revolutions

Joan Robinson's association with three Cambridge ‘revolutions’—imperfect competition, effective demand and capital theory—is examined in the context of her personal and intellectual partnership with Richard Kahn, John Maynard Keynes and Piero Sraffa. Initially, imperfect competition appeared to have successfully extended marginal analysis to all market forms. It also allowed Richard Kahn and Joan Robinson to persuade Keynes to present the main argument of The General Theory in terms of aggregate demand and aggregate supply. By the early 1950s, however, Joan Robinson had rejected the Marshallian methodology and had become a strenuous censor of neoclassical theory. In this paper the origin of her critique is traced to her reading of Sraffa's Introduction to Ricardo's Principles.     

'Interrelated prices' and Sraffa's critique of partial equilibrium

The early Marshallian literature recognized that, in most significant cases, long-period equilibrium analysis must consider families of interdependent markets which are in direct relation with each other. This perspective, which is different from both standard partial equilibrium and general equilibrium analysis, was developed mainly by two Italian authors, Maffeo Pantaleoni (1857–1924) and Marco Fanno (1878–1964). This paper is aimed at showing that this ‘interrelated prices’ literature has some points of contact with Piero Sraffa's critique of partial equilibrium analysis. It is argued that Sraffa places the case of a Marshallian decreasing returns industry in a context (rivalry for the use of a common factor in fixed supply) which was familiar to Pantaleoni-Fanno: both maintain that the markets involved are interdependent, even though they evaluate differently the possibility of a sensible equilibrium analysis.     

Long-period Positions and Economic Change. A rejoinder

Roncaglia and Nell have criticised the interpretation of Sraffa's normal prices as centres of gravitation for actual prices. Roncaglia mainly focuses on the interpretation of the notion of gravitation in Smith and on the meaning of the ‘given outputs’ in Sraffa. Nell attempts to confine the relevance of Sraffa's theory to specific historical circumstances and to find a role for Sraffa's prices in his version of post-Keynesian price theory. This rejoinder criticises the case made by both Roncaglia and Nell, and defends Sraffa's centre of gravitation view.     

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.     

Sraffa,interdependence and demand: the Gramscian influence

The influence of Sraffa' early commitments to Gramscian Marxism on his subsequent economic analysis have been little investigated by Sraffa scholars. The discussion here argues for a philosophical connection. Specifically, it is argued that organicist ideas found their way into Sraffa's thinking about interdependence in his 1926 critique of Marshall, in his reported critique of Wittgenstein's early philosophy, and in his 1960 Production of commodities. In each instance, atomist views were challenged in an understanding of agent or sectoral interdependence that made use a single criterion for agent or sectoral autonomy: that such autonomy depends upon the fulfilment of identify conditions for the individuation of autonomous agents or sectors. It is suggested that Sraffa's thinking in this regard ses the attempted fulfilment of these conditions in neoclassical theory as self-contradictory, thus allowing the characterization of his thinking as a form of impossibility logic. This impossibility logic is contrasted to that of Arrow, in order to advance general propositions about Sraffa's understanding of demand.     

Against the current: Sraffa's unpublished manuscripts and the history of economic thought *

The paper throws some new light on Sraffa's contribution, using material from his yet unpublished papers. Attention focuses on Sraffa's rediscovery of the distinct character of the classical theory of value and distribution and his refutation of the Marshallian interpretation that it is only a special case of demand and supply theory, his reformulation of the classical theory, and his criticism of the alternative neoclassical theory.     

The 'Sussex School' and the history of economic thought: British Intellectual History, 1750-1950

After a brief survey of the Japanese literature on Sraffa, the author explains how his own theory of the microfoundations of Keynesian macro-economics was influenced by Sraff's view of competitive markets. This view can be interpreted that firms perceive kinked demand curves. It is emphasized that Azariadis's theory of implicit contracts can explain unemployment only if we take Sraffa's not Walras's, view of competitive market.     

The Sraffian schools

After briefly recalling Sraffa's own contribution, the article surveys the ensuing debate, concerning both the critique of the marignalist theory, the revival of the classical approach, and the analytical contributions on specific aspects of Sraffa's 1960 book. Three lines of research for a modern reconstruction of th classical approach are then illustrated: Pasinetti's lsquo;Ricardianrsquo; reconstruction, Garegnani's lsquo;Marxianrsquo; reconstruction, and Sylos Labini's lsquo;Smithianrsquo; reconstruction. Finally, an assessment of these three research lines is provided, together with some suggestion for their integration.     

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.     

On re-reading Joan Robinson's ‘On re-reading Marx’

This paper offers some reflections inspired by a re-reading of Joan Robinson's On Re-reading Marx on the 50th anniversary of its initial publication. Robinson wrote the pamphlet in the light of Sraffa's Introduction to Ricardo's Works and Correspondence, which suggested to her that the concept of the rate of profit was essentially the same in Ricardo, Marx, Marshall and Keynes. In addition to the connections among Ricardo, Marx, Marshall and Keynes, Robinson also addresses the issues of equilibrium and time, and the dogmatism of Marxism.     

Sraffa: the theoretical world of the ‘old classical economists’ *

Sraffa's mature work is seen here as a re-discovery and resumption of the ‘submerged and forgotten’ approach of the ‘old classical economists from Adam Smith to Ricardo’. Wages determined by broad economic and social forces entail there product prices determined independently of demand and supply functions. Some main questions raised for the modern economists by this radical reorientation of economic theory are then considered in order to conclude that it is aginst that background that Sraffa's mature work should be set with its three main contributions, of a rediscovery of the approach, of a complete and transparent solution of the problems of price determination it raises, and of its application to the critique of neoclassical theory. Among several developments originating from Sraffa's seminal work, two are singled out for mention: (i) the possibility of deficiencies of aggregate demand in the long period no less than in the short one; this follows naturally from the abandonment of the neoclassical theory of distribution, of which the role of the interset rate in equilibrating savings and investment is a corollary; (ii) the question of the distribution of the surplus between wages and profits in a modern economy where wages are no longer confined to subsistence.
