Price–value deviations: further evidence from input–output data of Japan

This paper subjects to empirical testing the labour theory of value using input–output data from the economy of Japan for the years 1970, 1975, 1980, 1985 and 1990. The results of the analysis show that labour values and prices of production are extremely good approximations to market prices. In fact, the proximity of prices of production to market prices is closer than that of labour values, a result which suggests that prices of production constitute more concrete centres of gravitation for market prices. Furthermore, we find that prices of production change as a result of variations in income distribution more often than not in a monotonic way and that in fewer cases they display curvatures, which may even reverse the order between prices of production and values.     

Monetary Expressions of Labour Time and Market Prices: Theory and Evidence from China,Japan and Korea

This article presents estimates of labour values and prices of production following two approaches: the first is based on the classical and Marxian theory of value and distribution; the second on the so-called ‘new solution’ to the ‘transformation problem’ and its variant, the Temporary Single-System Interpretation (TSSI). The major advantage of the latter approach is its simplicity, along with the relatively low data requirements. Our empirical findings from the economies of China, Japan and South Korea suggest that both approaches give estimates of labour values and prices of production which are extremely close to each other as well as to actual market prices. On further examination, however, we conclude that our empirical findings are absolutely consistent with the theoretical requirements of the classical approach and contradict those of the TSSI.     

Sector and importer determinants of prices for traded intermediates

While the literature on traded goods prices emphasizes final goods prices and related consumer theory to explain variation in goods prices with importer characteristics, trade in intermediates actually constitutes about two thirds of total trade. We propose a mechanism for explaining variations in the prices of intermediates as a function of importer characteristics, wherein production is vulnerable to failure and the probability of failure declines in the quality of intermediates. Higher wages mean a greater opportunity cost of failure, leading to a stronger demand for high-quality intermediates where firms face higher wages. We find empirical support for this mechanism in the case of intermediate goods using IV regressions. In addition, our findings indicate that while the cost of labour explains about one fifth of variation in imported intermediate prices, it is a non-significant determinant of imported final goods prices.     

Using Micro Data to Test the Divergence between Prices and Labour Values

An extremely robust finding in Marxian empirical economics is the 'Shaikh result' that estimates of labour values are closely correlated with prices. This result is established using input-output data together with a standard procedure in which variations in money wages are assumed to reflect labour quality. Two problems with this standard procedure can be identified. First, there is no translation between money units of wages and labour value units of output produced by different types of heterogeneous labour. Second, the standard procedure assumes perfectly competitive labour markets. In this paper, a new micro procedure for estimating labour values is developed in which both of these problems are addressed. To translate between money wage rates and the labour value of outputs a practical starting point for empirical analysis is suggested using some of the readily available tools of neoclassical economics. The assumption of perfect competition is accordingly relaxed by estimating a microeconometric wage equation using data from the UK Family Expenditure Survey. Conjoining this micro data with input-output data, estimates of labour values are used to test the Shaikh result, which is found not to hold in this particular exercise; with labour values diverging substantially from money prices.     

Auction prices, market share, and a common agent

The primary pro-competitive justification for multiple principals to hire a common bidding agent is efficiency. The efficiency gained by doing so increases the advantage of the common bidding agent. Almost common value auction theory predicts that an advantaged bidder is able to reduce competition by credibly enhancing the ‘winner's curse’ of disadvantaged rivals. The credible threat results in disadvantaged rivals exiting the bidding process early, leaving the advantaged bidder to purchase most, if not all, units at lower prices than when rivals have common values. The results of our empirical study of a common bidding agent are consistent with this theory.     

The Emergence of the Law of Value in a Dynamic Simple Commodity Economy

Abstract

A dynamic computational model of a simple commodity economy is examined and a theory of the relationship between commodity values, market prices and the efficient division of social labour is developed. The main conclusions are: (i) the labour value of a commodity is an attractor for its market price; (ii) market prices are error signals that function to allocate the available social labour between sectors of production; and (iii) the tendency of prices to approach labour values is the monetary expression of the tendency of a simple commodity economy to allocate social labour efficiently. The model demonstrates that, in the special case of simple commodity production, Marx's law of value can naturally emerge from multiple local exchanges and operate ‘behind the backs’ of actors solely via money flows that place budget constraints on their local evaluations of commodity prices, which are otherwise subjective and unconstrained.     

Testing Böhm-Bawerk’s theory of capital: Some evidence from the Finnish economy

This paper considers the pure labour theory of value and Böhm-Bawerk’s theory of capital as approximations of Sraffa’s model of single production, and tests them with data from the Symmetric Input-output Tables of the Finnish economy. The results show that (i) in comparison with the labour values, the actual Böhm-Bawerkian production prices are ‘equally’ good or even better approximations of the actual Sraffian production prices and market prices; and (ii) the Sraffian production price-profit rate relationship is, by and large, governed by the differences in the Böhm-Bawerkian average periods of production.     

A note on the organic composition of capital and profit rates

It is widely believed that the rate of profit across industrialsectors, while not in fact uniform as stipulated in the theoryof prices of production, is independent of the sectoral organiccomposition of capital. It follows that the simple labour theoryof value must be systematically in error as a predictor of actualsectoral aggregate prices. We offer empirical evidence fromthe US economy (1987 input–output table) suggesting thatthis is not so: there is a substantial and statistically significantnegative association between organic composition and profitrate across sectors.     

Viewpoint: Option prices, preferences, and state variables

Abstract.  This paper surveys recent developments in the theory of option pricing. The emphasis is on the interplay between option prices and investors' impatience and their aversion to risk. The traditional view, steeped in the risk‐neutral approach to derivative pricing, has been that these preferences play no role in the determination of option prices. However, the usual lognormality assumption required to obtain preference‐free option pricing formulas is at odds with the empirical properties of financial assets. The lognormality assumption is easily reconcilable with those properties by the introduction of a latent state variable whose values can be interpreted as the states of the economy. The presence of a covariance risk with the state variable makes option prices depend explicitly on preferences. Generalized option pricing formulas, in which preferences matter, can explain several well‐known empirical biases associated with preference‐free models such as that of Black and Scholes (1973) and the stochastic volatility extensions of Hull and White (1987) and Heston (1993) .     

Measurement of export prices and changes in product quality

In this paper, the economic theory of index numbers is applied to the construction of industry-level export price indices and export quality indices. These indices are used to make consistent comparisons of export prices and qualities at the same or different points in time. Evidence of quality change over time was found to be an important phenomenon in explaining the variation of unit value indices over time and across countries for some European Union trade flows. About half of the unit value differences among destination countries can be explained by quality differentials. The quality-corrected price indices are potentially useful in any empirical application in which accurate measures of export prices are needed.The authors wish to thank Bienvenido S. Cortés for valuable discussion at the Forty-Eighth International Atlantic Economic Conference, October 7–10, 1999, Montreal, Canada.     

The law of value and laws of statistics: sectoral values and prices in the US economy, 1977-97

This study replicates findings that sectoral prices and valuesare highly correlated cross-sectionally, and that deviationsbetween them are small. Yet after controlling for variationsin industry size that produce ‘spurious correlation’,I find no reliable evidence that relative values have any influenceupon relative prices. The smallness of price–value deviationsthus does not result from such an influence; it is shown insteadto result from a lack of dispersion in the data. Values turnout to be no better predictors of prices than any other randomvariable with the same probability distribution.     

Tooke's approach to explaining prices

This paper examines the method of analysis and theoretical approach Thomas Tooke (1774–1858) employed in his empirical study of English prices. It is shown that Tooke adopted the “long period method” formulated by Adam Smith to analyse a capitalist society. It is shown that like most nineteenth-century classical economists, Tooke adopted a modified version of Adam Smith's “adding-up” approach to normal prices and distribution which incoporated Ricardo's theory of rent. The paper shows that based on this approach, Tooke explained short-run fluctuations in prices be reference to factors that disrupted the adjustment of supply to the “effectual” demand for commodities.     

Valuation of ecosystem services from rural landscapes using agricultural land prices

Agricultural lands, primarily managed for crops and livestock production, provide various ecosystem services (ES) to people. In theory, the economic value of the service flows that can be captured privately is capitalized into land prices. This study proposes an integrative framework to characterize the ecosystem services associated with agricultural lands. Using that framework, we demonstrate how hedonic analysis of agricultural land prices can be used to estimate the private values of land-based ES. The model is estimated with data from southwestern Michigan, USA. Results suggest that ES values are associated with lakes, rivers, wetlands, forests and conservation lands in rural landscapes. Ecosystem services that support direct use values, such as recreational and aesthetic services, are likely to be perceived by land owners and capitalized in land prices. Some regulating services that provide indirect use values may be partially capitalized in a land parcel's relationship to natural resources and landscapes. Other ES from the land parcel and its surroundings are unlikely to be capitalized due to lack of private incentives, unawareness, or small perceived value. The private ES values measured in this study highlight opportunities to design cost-effective public policies that factor in the value of private benefits from agricultural lands.     

Robust correlations between prices and labour values: a comment

The paper addresses Kliman's criticisms of the observed correlationsbetween prices and labour values. It argues that the notionof spurious correlation is not relevant in this case. It examinesKliman's own simulations and shows that his statistical correctiontechniques involve dividing through by the signal to leave thenoise.     

Value and Exploitation: A counterfactual approach

A deconstruction of the Marxian theories of value and exploitation is attempted by arguing, first, that the labour theory of value is logically and methodologically inconsistent as a basis for a theory of capitalist exploitation and, second, that it is founded on an ontology of the social being which is not plausibly justified. A counterfactual model economy is then built, called Utopia, in which the workers receive the whole net output while commodities exchange at labour values. This model is used as a benchmark to evaluate a capitalist economy where commodities exchange at production prices and workers are exploited. It is shown that the factor of exploitation can be expressed as a ratio between the labour commanded by, and the labour contained in, the net output, or between the value added produced in a capitalist economy and that produced in Utopia. The resulting theory of exploitation entails a weak ontology of the social being, expressing a worker's point of view.     

The behaviour of producer prices: evidence from French PPI micro data

This paper provides some new empirical findings for how French producers set prices. We used the micro data that composes the producer and business-service price indices from 1994 to 2005. First we address how producer prices are collected. Then we present the main characteristics of how producers change their prices: they are modified infrequently and in small amounts. Also, a behavioural heterogeneity across sectors is observed. Business-service prices change less often than industrial producer prices. The data corroborates both time and state-dependent model predictions. Taylor contracts are not unusual, but a firm’s prices will also react to its economic situation. Nevertheless, the most relevant models, to explain producer price rigidity, are time-dependent.

“The fact that some prices are rigid or sticky, while others are variable, has attracted a good deal of comments from economists in recent years” Tucker (1938)

This study was conducted in the context of the Eurosystem Inflation Persistence Network. Data were processed under the responsibility of INSEE in the context of an agreement between INSEE and the Banque de France (20B-21B-E301/R05019/2005).     

Employment and asset prices

A medium-term relationship exists between share prices, normalized by labour productivity, and the rate of unemployment in the Organization for Economic Co-operation and Development (OECD) countries. This helps explain decadal changes in mean unemployment, such as the shift to higher mean unemployment in the Continental European countries in the 1970s and 1980s that coincided with a fall in the level of share prices, as well as differences in mean unemployment between countries.     

The cyclical behaviour of prices in the U.K.: Some structural time series evidence

The cyclical behaviour of prices in the U.K. is investigated using a sample of annual observations covering the period 1886–1993. A structural time series model relating consumer prices to output is estimated over four sub-periods. The results indicate that prices were procyclical in the inter-war period, countercyclical in the post-1973 period and acyclical otherwise. The proposition that the cyclical behaviour of prices is determined by the dominance of supply or demand shocks alone is disputed on the basis of empirical evidence and theoretical reasoning. It is concluded that the cyclical behaviour of prices cannot be explained just by analysing time series on output and prices and that due attention should be paid to the institutional and policy changes occurring during the period under study. It is demonstrated that the empirical results are consistent with the events experienced by the U.K. economy in the most recent period.

Worksharing and factor prices

The aspect of worksharing on which this paper concentrates concerns an increase in the firm's workforce offset by a reduction in average working hours. Emphasis is given to the effect of relative factor prices on worksharing within a model structure which includes the capital stock and worker productivity as endogenous inputs. Factor prices include all the main categories of wage and non-wage labour payments as well as the user cost of capital. Special attention is given to the role of non-wages, both quasi-fixed and variable. An analysis of the effects of marginal employment subsidies on worksharing is also considered with reference to the French ‘solidarity contracts’.
