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.     

The friendship between Piero Sraffa and Antonio Gramsci in the years 1919-1927

This paper is part of a research on Piero Sraffa's biography and studies the relationship between Piero Sraffa and the Italian Communist leader and political theoretician Antonio Gramsci during the years 1919–1927. This period extends from the beginning of their friendship to the first year of Gramsci's imprisonment (he was arrested in November 1926), which was also the year of Sraffa's departure for England, where he settled as a lecturer at the University of Cambridge.     

Stable partitions in a model with group-dependent feasible sets

Summary. In this paper we consider a model of group formation where group of individuals may have different feasible sets. We focus on two polar cases, increasing returns, when the set of feasible alternatives increases if a new member joins the group, and decreasing returns, when a new member has an opposite effect and reduces the number of alternatives available for the enlarged group. We examine two notions, stability and strong stability of group structures, that correspond to Nash and Strong Nash equilibrium of the associated non-cooperative game, and identify the classes of stable and strongly stable environments.Received: 29 June 2003, Revised: 17 February 2004, JEL Classification Numbers: C71, C72, D62, D71.The previos version of this paper has been written while the second author was visiting the Technical University of Dresden.

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.     

Financial capital and banks in Hilferding and Sraffa: lessons for today

Rudolf Hilferding’s Das Finanzkapital dealt with the increasing role of finance in the German economy and the resulting structural transformations. The young Sraffa shared with Hilferding an interest on the role played by the banks in the transformation of capitalism. The relationship among banking and industrial capital implied different business models of the German and UK banks and determined the resulting domination of financial capital on the economy. We deepen the methodological and practical similarities and differences of the two scholars, discussing the aspects that are still relevant today to understand financialisation and instability of capitalism.     

评西方马克思主义者与斯拉法主义者关于利润确定模型的争论

西方马克思主义者赖特回应了各种非马克思主义的利润确定观点,但是却受到斯拉法主义者的进一步批评。实际上,赖特对于马克思主义利润确定模型的辩护,是在错误理解马克思价值转型理论的基础上做出的。他完全没有真正理解马克思的价值分析所使用的方法,因此对于不能提供因果解释的批判不知所措;他没有理解马克思价值到生产价格的转型理论,从而不理解马克思的劳动价值论作为一种价值理论体系如何揭示了利润在质和量上的确定。赖特对马克思利润确定模型的修改实际上放弃了利润是剩余价值转化形式的马克思主义基本观点,不仅不能有效回击斯拉法主义对马克思主义分析方法的批评,反而损害了马克思原本的理论。     

Competition,Fisher's Principle and increasing returns in the selection process

This paper explores the relationship between increasing returns and structural change in the context of an explicitly evolutionary model. The central theme concerns the behaviour of a population of competing firms which is elaborated in terms of Fisher's Principle, the rate of change of the moments of this population distribution are functionally related to higher order moments of the. distribution. Different kinds of increasing returns are distinguished and it is shown how they influence the dynamics of selection. The basic principles here are those of replicator dynamic, systems, and it is shown how the Fisher Principle interacts with the more familiar Kaldor/Verdoorn principles of endogenous growth.     

Government Spending and Welfare with Returns to Specialization

We explore a novel channel through which government spending can stimulate consumption and welfare through its effects on aggregate productivity, without directly affecting either utility or production possibilities. In the presence of monopolistic competition and increasing returns to specialization, it is shown that government spending can partly alleviate the inefficiencies of monopolistic competition. This is because government spending generates an endogenous increase in total factor productivity by increasing the variety of intermediate goods. If the degree of increasing returns to variety is large enough, a rise in such wasteful government spending may increase consumption levels enough to increase welfare.

Increasing returns,entrepreneurship and imperfect competition

We study a simple bilateral oligopoly model in which individual agents, who are initially endowed with capital, decide sequentially (1) whether they want to act as producers (entrepreneurs) or as capital lenders (rentiers) and, then (2) which quantity of capital they would like to borrow or lend, though exchange of capital units against units of the produced good. Production takes place under increasing returns to scale. We show the existence of “natural equilibria”, at which wealthier capital owners become entrepreneurs while the remaining ones decide to be rentiers. We also study the efficiency of equilibria which is shown to increase by replication of the economy, but sometimes to decrease as a consequence of wealth redistribution.We thank an anonymous referee for his insightful comments     

Returns to scale and externalities in the consumption and investment sectors

Using data on US manufacturing, I estimate internal returns to scale and external effects for the consumption and investment sectors. I construct panels of data at the industry level and use results of gross output production function estimation to derive implied estimates in a value added specification. For the investment sector, returns to scale appear to be slightly increasing, with evidence of a positive external effect. For consumption, the evidence indicates decreasing to constant returns to scale. I discuss the implications of these results for the empirical plausibility of indeterminacy in recent multi-sector models of the business cycle.     

Parametric external economies and the Cambridge controversy on returns

Abstract

When French economists read The Purchasing Power of Money, they were primarily interested in the equation of exchange and the reformulation that Fisher proposed regarding the quantity theory of money. This reading led them to ponder the meaning that should be given to this theory and to study its empirical significance. Some of them, namely Rueff and Divisia, went further still and considered Fisher's work as a starting point for their own analyses, which were related in particular to the monetary index, the integration of money into general equilibrium theory and the analysis of monetary phenomena in an open economy.     

Adaptive economic growth

This paper develops an evolutionary theory of adaptive growth,understood as a product of structural change and economic self-transformation,based upon processes that are closely connected with but notreducible to the growth of knowledge. The dominant connectingtheme is enterprise, the innovative variations it generatesand the multiple connections between investment, innovation,demand and structural transformation in the market process.The paper explores the dependence of macroeconomic productivitygrowth on the diversity of technical progress functions andincome elasticities of demand at the industry level, and theresolution of this diversity into patterns of economic changethrough market processes. It is shown how industry growth ratesare constrained by higher-order processes of emergence thatconvert an ensemble of industry growth rates into an aggregaterate of growth. The growth of productivity, output and employmentare determined mutually and endogenously, and their values dependon the variation in the primary causal influences in the system.     

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.     

Competition among techniques in the presence of increasing returns to scale

A model of technology diffusion and growth originally proposed by Batten (1987), taking into account the interaction of the supply of and demand for a new product, is modified so as to admit a production technology with increasing returns to scale and the possibility of a competition between two techniques. On the opposite to the case where the production technology of the new technique exhibits decreasing returns, the presence of increasing returns to scale prevent the splitting of the market between two new techniques, and the monopoly position of one technique must obtain. The winning technique may not be the most efficient in terms of its market expansion potential, the outcome of competition depends on initial conditions on production capacity and diffusion.The author wishes to thank Robert Boyer for his helpful advice and remains the sole responsible for all remaining errors and omissions.     

Prices versus Rationing: Marshallian Surplus and Mandatory Water Restrictions*

An aggregate daily water demand for Sydney is estimated and used to calculate the difference in Marshallian surplus between using the metered price of household water to regulate total consumption versus mandatory water restrictions for the period 2004/2005. The loss in Marshallian surplus from using mandatory water restrictions is calculated to be $235 million. On a per capita basis this equates to approximately $55 per person or about $150 per household – a little less than half the average Sydney household water bill in 2005.     

The discrete time version of the Romer model

Summary. This paper presents a discrete time version of the Romer 1986 model of endogenous growth. The purpose of this work is to propose detailed and simple proofs of existence of optimal solutions and of a competitive equilibrium. The framework implemented here reduces the complexity of the proofs given by Romer (1983) in his Ph.D dissertation in a continuous time framework.

Increasing returns to savings and wealth inequality

In this paper I present an explanation to the fact that in the data wealth is substantially more concentrated than income. Starting from the observation that the composition of households' portfolios changes towards a larger share of high-yield assets as the level of net worth increases, I first use data on historical asset returns and portfolio composition by wealth level to construct an empirical return function. I then augment an Overlapping Generation version of the standard neoclassical growth model with idiosyncratic labor income risk and missing insurance markets to allow for returns on savings to be increasing in the level of accumulated assets. The quantitative properties of the model are examined and show that an empirically plausible difference between the return faced by poor and wealthy agents is able to generate a substantial increase in wealth inequality compared to the basic model, enough to match the Gini index and all but the top 1 percentile of the US distribution of wealth.
