Pasinetti,Keynes and the multiplier

This paper explores the relationship between the Keynesian multiplier and Pasinetti's model of pure production. Key assumptions of Pasinetti's model are its multisectoral structure, the definition of all income as a reward to labouring activities and, as a consequence, the operation of a pure labour theory of value. A translation between these models is effected by introducing investment as an exogenous determinant. By drawing from Keynes to apply his concept of the wage unit, it is possible to aggregate from Pasinetti's multisectoral model to a genuinely macroeconomic multiplier. This provides a way of using the scalar Keynesian multiplier without making the restrictive one-commodity assumption. In addition, this formal demonstration enhances our understanding of the relationship between the wage unit and the labour theory of value. Finally, critics have argued that Pasinetti downgrades the importance of institutional analysis; in contrast, the derivation of a scalar Keynesian multiplier contributes to an understanding of how relevant Pasinetti's approach is to the analysis of a monetary production economy.     

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.     

Wages and profits

Wages and profits must be regarded as simultaneously determined—profits must not be regarded as a residual. In the short period both are determined by current demand, profits fluctuating much more strongly than wages. More important is the long-period factor, which depends upon capital-labor substitution elasticity.     

The outcome of the Pasinetti process reconsidered: A note

Conclusion By introducing into the Pasinetti model the plausible assumption that workers and capitalists, respectively, maximize their consumption over time, it has been shown, that only with a well-behaved production function may the long-run outcome of the Pasinetti process be considered as an equilibrium position. In all other cases capitalists can increase their steadystate level of consumption without sacrificing any consumption today. As the maximal capitalists' consumption per head is determined by the technical conditions of production, the profit rate isnot independent of those conditions. We have not taken into account all problems of stability of the steady-state paths or the question of utility maximization over time, i. e. optimal saving; the former because the analysis of the transition processes are very difficult, the latter because of the dubious assumptions, which are necessary to get some convenient results.     

Taxation of profits when there are profits

Profits taxes fall on both pure profits and the use of capital as an input. Simulations of a Cournot oligopoly suggest that gains from the former are not outweighed by losses from the latter.     

Entry and Schumpeterian profits

A large empirical literature has documented differences in Schumpeterian profits, both among firms in single industries and between firms in different industries. Theorists have proposed various institutional and strategic factors to account for such differences but have had relatively little to say about the manner in which technology affects entry and profits. In this paper I present a model in which persistent intraindustry differences in firm profitability arise as the outcomes of learning and imitation, and interindustry differences in the persistence of above normal profits arise solely from production being more technologically complex in some industries than in others.     

Wages and profits: A comment

Clark's (1979) model for the levels of aggregate wages and profits is respecified and reestimated using modern econometric techniques. One result is a more efficient estimate of the capital-labor substitution elasticity. In addition, the presence of very strong positive autocorrelation in one of the equations sheds doubt on Clark's assertion that a model for the levels of these variables is more appropriate than a model for their year-to-year changes.     

A model of profits and market adjustment

A market adjustment process is analyzed, where the prevailing rate of profit affects the rates of change of quantity produced and unit cost of production. Only under special conditions does the process lead to a steady-state where the rate of profit is zero.     

On Torrens's theory of profits

This paper is about the presence in Torrens's works of the 1810sand 1820s of a theory of profits based on an assumption of physicalhomogeneity between capital and product—a theory thatderived from the ‘corn ratio’ theory of profitsput forward by Ricardo in 1814–15. Some views about Torrens'stheory and its Ricardian origin held by S. Hollander and T.Peach are also briefly discussed and are shown not to be wellfounded, and not to take into account correctly the evolutionof Torrens's views on distribution.     

Capitalism, profits and innovation in the new techno-economic paradigm

Innovative profits (of the kind conceptualized by Schumpeter) are today being increasingly created through international corporate networks for technological development. Such profits through innovation are encouraged by newer more flexible organizational forms, and further encouraged (unlike in the conventional perspective on profits and on the incentive to innovate) by knowledge flows between firms. Our empirical evidence, based on US patent data, shows that multinational companies are currently more likely to develop abroad technologies which are less science-based, and less dependent upon tacit knowledge. However, within the science-based industries firms may generate abroad some technologies which are heavily dependent on tacit knowledge, but normally in fields that lie outside their own core technological competencies. We find some evidence of a convergence in corporate technological diversification across large firms, facilitated by the now common spread in the use of information and communication technologies (ICT) as an integrator of formerly separate technological systems. This has led smaller firms to diversify, but giant firms to consolidate activity around those technologies that have become most interrelated.     

Growth,profits and foreign ownership in the Brazilian banking industry

The deregulation of the financial markets and their progressive globalization has favoured the internationalization of banking. Moreover, during the international financial crisis, the presence of foreign banks has increased in countries experiencing faster economic growth, such as Brazil. In this context, the aim of this study is to analyze the growth and profitability of the financial institutions in Brazil, taking into account the possible non-linearity of the relationship, the differences between Brazilian and foreign institutions and the effect of the crisis. Our results indicate that the entry of foreign institutions has a direct effect on the Brazilian banking industry.     

Modelling profits and industrial investment in postwar Greece

This article examines the two contrasting phases of the industrial capital accumulation in postwar Greece. It is argued that the phase of rapid accumulation can be explained by the emergence and consolidation of institutionalized power relations that comprised the Greek social structure of accumulation (SSA). The deindustrialization process that followed can be explained as the result of the demise of the very same institutional setting. A recursive system of two equations models the SSA-profitability-accumulation nexus. The profit rate is found to be highly sensitive to changes in the (quantified) dimensions of the power relations. The capital accumulation rate, in turn, is found to be sensitive to expected profitability, capital cost, and volatility of international trade.     

Bounding consumer surplus by monopoly profits

Regulatory agencies and other public authorities in the United States frequently require private firms seeking regulatory approvals to enter geographic markets, or offer products, that they would not otherwise provide. Examples include “build-out” rules for cable television franchisees, and universal service or “common carrier” obligations. The social welfare consequences of such policies are often difficult to evaluate because, among other things, consumer surpluses generated by entry must be assessed. This article shows that the level of (variable) monopoly profits in the markets of interest can be used to place an upper bound on the associated consumer surplus whenever demand vanishes at a sufficiently high price. This result, which is new, can then be used to evaluate the social consequences of forced entry. Our methods can also be used to provide a bound on the change in consumer surplus resulting from the imposition of regulated prices on an existing monopoly.      

When curiosity kills the profits: An experimental examination

Economic theory predicts that in a first-price auction with equal and observable valuations, bidders earn zero profits. Theory also predicts that if valuations are not common knowledge, then since it is weakly dominated to bid your valuation, bidders will bid less and earn positive profits. Hence, rational players in an auction game should prefer less public information. We are perhaps more used to seeing these results in the equivalent Bertrand setting. In our experimental auction, we find that individuals without information on each other's valuations earn more profits than those with common knowledge. However, given a choice between the two sets of rules, approximately half the individuals preferred to have the public information. We discuss possible explanations, including showing that there is a correlation between ambiguity aversion and a preference for having more information in the auction.     

The recent rise of profits in the United States

Profitability in the United States has been rising since the early 1980s, and by 1997 was nearing its postwar peak in the mid-1960s. The profit share has also recovered from its postwar low in the early 1970s. In this paper, I examine the role of the change in the profit share and capital intensity on movements in the rate of profit between 1947 and 1997. Its recent recovery is traced to a rise in the profit share in national income and a decline in the capital-output ratio.     

The common pool of transitional profits

Transitional profits are above-normal profits that can be earned by firms as a result of changes in market conditions or entrepreneurial innovations of the firm. They are a common pool and are competed away by firms that enter profitable markets or imitate the innovations of profitable firms. The economics literature provides two conflicting views on transitional profits. One is that above-normal profit is a sign of economic inefficiency and is the result of either monopoly power or disequilibrium. The other is that economic profit is necessary for economic efficiency because profit is the lure that pushes entrepreneurs to allocate resources more efficiently. Both views are considered, along with an analysis of whether this common pool resource is competed away too rapidly, as the theory of common pool resources would suggest.     

Ozone pollution and farm profits in England and Wales

Tropospheric ozone is an air pollutant known to adversely affect crop yields across Europe. Experimental work is underway to quantify yield effects at ambient ozone levels for a number of crops. In this article, we undertake direct, farm-level evaluation of the impact of ozone by estimating a multi-output profit function using a panel dataset of cereal farms in England and Wales. A system of equations, comprising the profit function, input and output share equations is estimated using a fixed-effects seemingly unrelated regression technique, with ozone as a quasi-fixed input. Estimated parameters are used to calculate tropospheric ozone-related profit and output supply elasticities. The main findings from the profit function show that a 10% increase in average ozone levels would decrease variable profits by 1.3% and wheat output supply by 1%. These results are of a significantly lower magnitude, but qualitatively consistent with findings from similar studies carried out in North America.
