The Transformation Problem : an Aleternative Solution with an Identical Aggregate Profit Rate in the Labor value and the Monetary Space.

The aim of this paper is to demonstrate that, even if Marx's solution to the transformation problem can be modified, his basic conclusions remain valid. the proposed alternative solution which is presented hare is based on the constraint of a common general profit rate in both spaces and a money wage level which will be determined simultaneously with prices.

The Financial Rate of Profit: What Is It, and How Has It Behaved in the United States?

This work contributes to the almost nonexistent literature on the profit rate of the financial sector. It updates the single study to include financial variables to cover the past decade, compares this profit rate to the (almost unpublished) Weisskopf and NIPA financial profit rates, compares the financial and nonfinancial sector rates, and details the procedure to construct the profit rate in the financial sector including relevant financial variables which capitalists consider to make profit-rate decisions.

Buy-and-Hold Strategies and Comonotonic Approximations

[cat] En aquest article estudiem estratègies “comprar i mantenir” per a problemes d’optimitzar la riquesa final en un context multi-període. Com que la riquesa final és una suma de variables aleatòries dependents, on cadascuna d’aquestes correspon a una quantitat de capital que s’ha invertit en un actiu particular en una data determinada, en primer lloc considerem aproximacions que redueixen l’aleatorietat multivariant al cas univariant. A continuació, aquestes aproximacions es fan servir per determinar les estratègies “comprar i mantenir” que optimitzen, per a un nivell de probabilitat donat, el VaR i el CLTE de la funció de distribució de la riquesa final. Aquest article complementa el treball de Dhaene et al. (2005), on es van considerar estratègies de reequilibri constant.

Por que a poupança externa não promove crescimento

Why foreign saving fail to cause growth. The present paper is a formalization of the critique of the growth with foreign savings strategy. Although medium income countries are capital poor, current account deficits (foreign savings), financed either by loans or by foreign direct investments, will not usually increase the rate of capital accumulation or will have little impact on it in so far as current account deficits will be associated with appreciated exchange rates, artificially increased real wages and salaries and high consumption levels. In consequence, the rate of substitution of foreign savings for domestic savings will be relatively high, and the country will get indebted to consume, not to invest and grow. Only when there are large investment opportunities, stimulated by a sizeable difference between the expected profit rate and the long term interest rate, the marginal propensity to consume will get down enough so that the additional income originated from foreign capital flows will be used for investment rather than for consumption. In this special case, the rate of substitution of foreign for domestic savings tend to be small, and foreign savings will contribute positively to growth.

Um modelo macrodinâmico pós-keynesiano de simulação

A post-keynesian macro-dynamic model of simulation. The objective of this article is to present the structure and the simulation results of a one-sector macro-dynamic model that embeds some elements of the post-keynesian theory. The computational simulation of the model replicates some important features of capitalist dynamics as the phenomenon of cyclical growth, the long-run stability of the profit rate and functional distribution of income, the maintenance of idle-capacity in the long-run and the occurrence of a single episode of deep fall in real economic activity, which is in accordance with the rarity character of great crashes in the history of capitalism. Moreover, the simulation results show that a great reduction in inflation rate will be followed by an increase of financial fragility, increasing the like-hood of a great depression. As a policy advice derived from the simulation results, we can state that the Central Bank should never promote big reductions in inflation rate.

The Brazilian deindustrialization: financialization is not guilty

The financialization of the Brazilian economy is often criticized as being responsible of the slowdown of capital accumulation in this country. Indeed, very high interest rates are maintained in order to finance the public debt, and this fosters capitalists to get more Treasury bonds rather than to invest in the productive area. Nevertheless, the evolution of the profit rate in this area also explains the particular relation existing between capitalists, finance and productive investment, as Marx showed it more than a century ago.

Why foreign savings fail to cause growth

Este artigo é uma formalização da crítica à estratégia do crescimento com poupança externa que um de seus autores vem sendo fazendo nos últimos anos. Apesar dos países de renda média serem pobres de capital, os déficits em conta corrente (poupança externa), financiado seja por empréstimos ou por investimentos externos diretos, não irá aumentar a taxa de acumulação de capital ou terá pouco impacto sobre ela, uma vez que os déficits de conta corrente estarão associados taxas de câmbio apreciadas, ordenados e salários aumentados artificialmente e altos níveis de consumo. Consequentemente, a taxa de substituição da poupança externa pela interna será relativamente alta, e o país será obrigado não a investir e crescer, mas a consumir. Apenas quando há grandes oportunidades de investimento, estimuladas por uma ampla diferença entre a taxa de lucro esperada e a taxa de juros de longo prazo, a propensão marginal ao consumo diminuirá suficientemente, a ponto de o lucro adicional originário do fluxo de capital estrangeiro ser usado para investimento, ao invés de para consumo. Neste caso especial, a taxa de substituição de poupança externa pela interna tenderá a ser menor e a poupança interna contribuirá positivamente para o crescimento

A tendência à queda da taxa de lucro: determinantes teóricos e a economia brasileira

Talvez seja excesso de pessimismo crer que se inicia a derrocada final do capitalismo. O fato, porém, é que esse sistema vem se defrontando com problemas para os quais não há ainda soluções visíveis, como a questão do emprego, por exemplo. As taxas mundiais de desemprego são elevadas e a globalização da economia tende a reforçar o desemprego estrutural. Daí a preocupação do G-7, que tem analisado o tema recorrentemente. O objetivo do presente trabalho, consiste na análise do comportamento apresentado pela taxa de lucro. Para tanto, ela será pensada de acordo com a interpretação marxista. Isto envolve uma análise teórica e empírica. Qualquer tentativa de estimação de conceitos marxistas, porém, deve abordar a questão da transformação de valores em preços.

The inequality curse: constraints and political discretion

We live in an unjust world characterized by economic inequality. No liberal theory of justice is able to justify it. Inequality is not “solved” with equality of opportunity or meritocracy. Nor by the socialist and republican critique. The poor will have to count with them and with democracy to make social progress reality. In their political struggle, they will face one economic constraint: the expected profit rate must remain attractive to business investors. Yet, giving that technological progress in increasingly capital-saving, this economic constraint does not obstruct that wages grow above the productivity rate and inequality is reduced. What really is an obstacle to social justice in the rich countries is, on one hand, the power that capitalist rentiers retain and financists acquired, and, on the other, the competition originated in low wage countries.

Growth and distribution: a revised classical model

This paper discusses distribution and the historical phases of capitalism. It assumes that technical progress and growth are taking place, and, given that, its question is on the functional distribution of income between labor and capital, having as reference classical theory of distribution and Marx’s falling tendency of the rate of profit. Based on the historical experience, it, first, inverts the model, making the rate of profit as the constant variable in the long run and the wage rate, as the residuum; second, it distinguishes three types of technical progress (capital-saving, neutral and capital-using) and applies it to the history of capitalism, having the UK and France as reference. Given these three types of technical progress, it distinguishes four phases of capitalist growth, where only the second is consistent with Marx prediction. The last phase, after World War II, should be, in principle, capital-saving, consistent with growth of wages above productivity. Instead, since the 1970s wages were kept stagnant in rich countries because of, first, the fact that the Information and Communication Technology Revolution proved to be highly capital using, opening room for a new wage of substitution of capital for labor; second, the new competition coming from developing countries; third, the emergence of the technobureaucratic or professional class; and, fourth, the new power of the neoliberal class coalition associating rentier capitalists and financiers

Viabilidade econômica de manejos nutricionais na cultura de banana

O manejo adequado da adubação, visando à otimização da produtividade e qualidade dos frutos, é uma etapa representativa do processo produtivo para rentabilidade do empreendedor rural. Neste contexto, objetivou-se analisar a viabilidade econômica de cinco tipos de manejo nutricional de bananeiras de cultivares do subgrupo Cavendish, na região do Médio Paranapanema (SP), em 2009/2010. Foram utilizadas estruturas do custo operacional efetivo (COE) e custo operacional total (COT) e três indicadores de rentabilidade. Diferenças significativas foram observadas entre os manejos, sendo que o sistema de manejo que resultou em maior vantagem econômica para o produtor proporcionou índice médio de lucratividade 25,6% superior aos demais tratamentos, além de a receita líquida total ser, em média, 29,5% superior aos outros tipos de manejo. O custo por unidade produzida foi inferior no manejo nutricional mais lucrativo, apesar de a produtividade ter sido 9,5% inferior ao manejo que apresentou os maiores índices de produtividade.

Marx's analysis of the falling rate of profit on the first version of volume III of capital

The paper provides a description and analysis of the Hodgskin section of Theories of Surplus Value and the general law section of the first version of Volume III of Capital. It then considers Part III of Volume III, the evolution of Marx's thought and various interpretations of his theory in the light of this analysis. It is suggested that Marx thought that the rate of profit must fall and even in the 1870s hoped to be able to provide a demonstration of this. However the main conclusions are: 1. Marx's major attempt to show that the rate of profit must fall occurred in the general law section. 2. Part III does not contain a demonstration that the rate of profit must fall. 3. Marx was never able to demonstrate that the rate of profit must fall and he was aware of this.
