MEASURES OF PRODUCTION PRICE-LABOUR VALUE DEVIATION AND INCOME DISTRIBUTION IN ACTUAL ECONOMIES: A NOTE (original) (raw)

Measures of Production price-labour value deviation and income distribution in actual economies: Theory and empirical evidence

Bulletin of Political Economy, 2014

Many empirical studies indicate that the deviations of actual prices of production from labour values are not too sensitive to the type of measure used for their evaluation. This paper attempts to theorize this rather ‘stylized fact’ by focusing on the relationships between the traditional and the numéraire-free measures of deviation. On the empirical side, it provides an illustration of these relationships using input-output data from the Greek and Japanese economies.

Price-Value Deviations and the Labour Theory of Value: Evidence from 42 Countries, 2000–2017

Review of Political Economy, 2022

The relationship between prices and labour values has been the source of fruitful controversy since the earliest Classical Political Economists. The alleged refutation of the labour theory of value was an integral part of the marginalist attack against Classical and Marxist analysis. However, statistical analysis of price-value relationships made possible by the data available since the later 20th century suggest considerable empirical strength of the labour theory of value. We trace the intellectual history of the price-value relationship and its inseparable link to capitalist competition through Smith, Ricardo, Marx and Sraffa. Following Shaikh and Ochoa, we present an empirical model of testing their hypotheses that (1) labour values regulate prices of production and (2) serve as gravitational centres for market prices. The analysis of a large dataset of 42 countries and 15 years reveal only small and stable deviations and thus lend support to the Classical Political Economic analysis. With a sample of over 36,000 price vectors, we provide the most comprehensive empirical application of its class and generalize the results that have been established in the relevant literature.

Measurement error and the distribution of income

A model for measurement error is developed, based on the assumption that measurement error is random, multiplicative, and independent of the level of actual income. Thus, measured income is defined as the product of actual income and measurement error. Flexible parametric forms are utilized to model the distributions of actual income (generalized gamma) and measurement error (inverse generalized gamma). The probability density of measured income is then derived as a generalized beta of the second kind (GB2). Estimation of the parameters of the GB2 (measured income), then allows an estimate to be made of the pdf of actual income, from which corresponding estimated means, variances, Gini coefficients, and Lorenz curves are obtained. An identification problem in the parameters of actual and measured income is solved with additional information as to the average fraction of actual income reported. The implied characteristics of measurement error are also obtained. The procedure is appli...

Distributional effects of true economic indexes

Economics Letters, 1984

integrable Working system parameter estimates are used to construct the true differential indexes of (a) the cost of living, (b) the real income, and (c) the marginal prices to study distributional effects of inflation and real income in Australia over the period 197O.IV to 1983.11. The findings provide useful results for disaggregate household analysis and reveal the severe bias of aggregate indexes in sectoral studies of economic welfare. 0165-1765/84/$3.00 0 1984, Elsevier Science Publishers B.V.

J-Divergence Measurements of Economic Inequality

Journal of the Royal Statistical Society Series A: Statistics in Society, 2015

Summary The paper uses a symmetric entropy statistic to study income inequality. The index quantifies the information content of a two-way message that transforms the empirical income distribution into an egalitarian reference distribution, and then back to the original. This allows the measure to be interpreted as an average of n income-to-mean divergences such that the inequality estimate can be broken down into contributions across population subgroups. Various properties of the index are analysed and an application comparing the USA, Germany and Britain is provided. We focus on the sensitivity of inequality to the tails of the income distribution and show that the extreme right-hand tail accounts for a large and generally increasing proportion of total inequality. This result holds even if incomes are measured at the household level, averaged over a 5-year period and taken after government taxes and transfers.

Some reflections on the dependence of prices on Labour-Values

2010

Con frecuencia se cree, de una manera bastante esquizofrénica, que una teoría del valor solo debe resolver la cuestión de los "precios relativos" (un problema microeconómico), siendo principalmente la teoría del dinero de la pieza necesaria para la determinación monetaria o del nivel absoluto de los precios (un problema macroeconómico). Por una parte, la determinación del nivel de precios se encuentra teóricamente antes de cualquier consideración del mercado de dinero, mientras que por otro lado ninguna teoría del valor puede aspirar a ser completa sin la determinación del nivel absoluto de los valores. Se verá en este trabajo que sólo la teoría del valor trabajo (TVL) puede realizar ambas tareas, produciendo así la integridad y la unidad de la teoría económica. Palabras clave: teoría del valor trabajo, precios relativos, valores absolutos.

Deviations from the Law of One Price in Japan

2008

Using 25 years of monthly data on individual Japanese retail prices, we study the behavior of product-specific Law of One Price (LOP) deviations. Individual tradable products, compared with nontradables, are more likely to have different distributions of LOP deviations across cities. Their distributions are also more likely to change over time. Individual LOP deviation series are found to display considerable persistence and there is limited evidence that tradability enhances price convergence. In addition, deviations from the LOP are found to display nonlinear trends, and these trends are not linearly related to a product's tradability. For individual products, LOP deviations are affected by their own inflation rates and, to a lesser extent, by aggregate inflation, output variations, and monetary variability. Interestingly, the trend behavior remains significant in the presence of these economic variables.

Testing Labour Value Theory with input/output tables

1993

Statistical measurement of the economic indices of Marxist political economy was pioneered during the 1950s by Gillman1 who used national income figures to obtain estimates of the rate of surplus value, organic composition of capital and rate of profit for the British economy. The measurements presented in this paper draw on his methodology. By the 1970s the empirical reality of a falling rate of profit in Britain drew attention both from orthodox2 and Marxist economists.

Comparison of the Gini and Zenga indexes using some theoretical income distributions abstract

Operations Research and Decisions, 2013

The most common measure of inequality used in scientific research is the Gini index. In 2007, Zenga proposed a new index of inequality that has all the appropriate properties of an measure of equality. In this paper, we compared the Gini and Zenga indexes, calculating these quantities for the few distributions frequently used for approximating distributions of income, that is, the lognormal, gamma, inverse Gauss, Weibull and Burr distributions. Within this limited examination, we have observed three main differences. First, the Zenga index increases more rapidly for low values of the variation and decreases more slowly when the variation approaches intermediate values from above. Second, the Zenga index seems to be better predicted by the variation. Third, although the Zenga index is always higher than the Gini one, the ordering of some pairs of cases may be inverted.
