Ricardo on Agricultural Improvements: a Note

This note discusses the numerical examples of land saving and capital saving agricultural improvements Ricardo provided in the chapter on the rent of land in the Principles. Especially his illustration of the second kind of improvements met with fierce criticism. It is argued that Ricardo was not wrong in any substantive sense and that he could only be criticized for having changed the definition of rent as regards the timing of its payment from post to ante factum.     

Marx on Ricardo: an explanation of some important misunderstandings

Ricardo's theory of value and distribution is reconstructed by proceeding along the lines of Marx's critique of Ricardo. It is thus an anti-critique of Marx's reading of Ricardo. The chapter ‘On Value’ in Ricardo's Principles is shown to be a consistent and rigorous treatment of the determinants of prices of production. According to Ricardo labor-values merely serve to approximate more elaborate standards of value. Marx's criticism is shown to rest crucially on his own misinterpretation of Ricardo's definitions and presupposes his own – faulty – theory of surplus value. Therefore Ricardo's theory can – contrary to Marx's theory of surplus value – still be regarded as a fruitful complement to Sraffa's model.     

From endogenous growth to stationary state: The world economy in the mathematical formulation of the Ricardian system

We analyse international trade in a Pasinetti–Ricardo growth model in the world economy scenario in which several small trading countries coexist and international commodity prices are determined by the interplay of supply and demand amongst them. We demonstrate that all the trading countries eventually reach the stationary state, though this process is not monotonic and the dynamics of capital and population may actually push some countries towards the stationary state and others away from it. We also use our model to assess an argument which Malthus employed in the second edition of An Essay on the Principle of Population (1803) to support a policy of agricultural protectionism.     

Marx and Ricardo on machinery: a critical note

This article critically discusses the important and relevant—not to mention controversial— views of Ricardo and Marx on the impact of machinery on labor productivity, the organization of production and the wages and employment prospects of the working class during the capitalism of their day. First, the article turns to Ricardo’s assessment of the introduction of machinery and its likely effects on the laborer and the rate of profit and accumulation—one which went through a substantial revision (and reversal) between the first and third editions of his Principles of Political Economy and Taxation. Then, we discuss Marx’s own critical analysis of the historical development of machinery and its impact on the labor process, the so-called “compensation principle,” and how the rising organic composition of capital ostensibly generates a “redundant or surplus-population” during the course of capitalist development. We highlight Marx’s intellectual debt to Ricardo, John Barton (and George Ramsay) insofar as his theory of technological unemployment is concerned. Lastly, the article summarizes the views of Ricardo and Marx and offers some concluding remarks.     

Tozer on machinery

This paper examines John Edward Tozer's mathematical treatment of the classical approach to the machinery problem and his discussion of some arithmetical examples that had been presented by Barton, Sismondi, McCulloch and Ricardo. It is shown that Tozer (1) made a genuine contribution to the contemporary debates on the machinery issue, (2) anticipated modern formulations of the problem of the choice of technique, and (3) revealed a puzzling inconsistency in Ricardo's argument in the famous chapter ‘On Machinery’.     

OPTIMAL CONTROL OF EXTERNALITIES IN THE PRESENCE OF INCOME TAXATION*

A substantial literature examines how the Pigouvian directive that marginal taxes should equal marginal external harms needs to be modified in light of the preexisting distortion due to labor income taxation. Additional literature considers distributive concerns. It is demonstrated, however, that simple first‐best rules—unmodified for labor supply distortion or distribution—are correct in the model examined. Specifically, setting all commodity taxes equal to marginal harms (and subsidies equal to marginal benefits) can generate a Pareto improvement, as can a marginal reform toward the first‐best. Qualifications and explanations for differences from previous work are also presented.     

关于三种价值论的评论

传统劳动价值论存在四大问题:一是社会必要劳动量难以计量;二是复杂劳动和简单劳动的倍加比例难以准确确定;三是无法解释自然产品为何也具有价值、价格;四是存在价值归属上的理论悖论。生产要素价值论不能全盘否定,但资本、土地不能“创造”价值,只能“生成”价值。边际效用价值论所揭示的边际效用递减规律是正确的;应当正确看待用效用衡量商品价值;事实上,马克思的商品价值论与边际效用价值论具有相通之处。     

Potential Environmental Impacts of Increased Reliance on Corn-Based Bioenergy

This paper integrates economic and physical models to assess: a) how increases in agricultural commodity prices, driven by ethanol production and other factors, affect land use and cropping systems in the US Midwest, and b) how the changes in land use and cropping systems in turn affect environmental quality in the region. The empirical framework includes a set of econometric models that predict land conversion, crop choices, and crop rotations at the parcel level based on commodity prices, land quality, climate conditions, and other physical characteristics at the sites. The predictions are then combined with site-specific environmental production functions to determine the effect of rising commodity prices on nitrate runoff and leaching, soil water and wind erosion, and carbon sequestration. Results suggest that increasing commodity prices will result in widespread conversions of non-cropland to cropland. Fifty percent of the region’s pasture and range land will be converted to cropland with 6 corn. Rising commodity prices will also result in dramatic changes in crop mix and rotation systems in the Midwest. With6 corn. Rising commodity prices will also result in dramatic changes in crop mix and rotation systems in the Midwest. With 6 corn, the total acreage of corn will increase by 23% and 40% in the Corn Belt and Lake States, respectively; the acreage of continuous corn will increase considerably in both regions as well. These changes in land use and crop mix will have a large impact on agricultural pollution. Approaches to mitigating the environmental impacts are discussed.     

Keynes,Ricardo and the classical theory of interest

Keynes made harsh and repeated attacks on the work of Ricardo, blaming him particulary for what Keynes called the ‘classical theory’ of interest. Garegnani and others argue that Keynes' criticisms of the classical theory of interest apply to later neoclassical writers, but not to Ricardo. This paper re-examines Keynes' criticisms. It argues that Keynes attacked Ricardoapos;s theory of interest despite his awareness that Ricardo did not hold the ‘classical theory’. Moreover, Keynes not only expressed sympathy for Ricardo's understanding of interest, but his criticisms which do apply to Ricardo do not address Ricardo's theory of interest.     

Externalities and optimal taxation

This paper reexamines the optimal tax design problem (income and commodities) in the presence of externalities. The nature of the second–best, and the choice of the tax instruments, are motivated by the informational structure in the economy. The main results are: (i) environmental levies (linear or nonlinear) differ in formula from Pigouvian taxes by the expressions for the optimal tax on private goods; (ii) externalities do not affect commodity tax formulas (linear and nonlinear) for private goods; (iii) externalities do not affect the income tax structure if commodity taxes are nonlinear and affect it if commodity taxes are linear; and (iv) a general income tax plus strictly Pigouvian taxes are sufficient for efficient taxation if individuals of different types have identical marginal rates of substitution (at any given consumption bundle).     

Does Technological Innovation Really Reduce Marginal Abatement Costs? Some Theory,Algebraic Evidence,and Policy Implications

The existing literature models innovation in pollution control as a reduction in marginal abatement costs. We show that this assumption is inappropriate for production process innovations such as fuel switching. Algebraically, we examine the effects of different innovation types on marginal abatement cost curves, showing that some desirable innovations increase marginal abatement costs. Empirically, we estimate marginal abatement costs for sulfur dioxide by measuring the output distance function for electric power in Korea. Regression results confirm that production process innovations did raise marginal abatement costs in this case. One policy implication: economic instruments do not always provide stronger innovation incentives than command-and-control policies.      

The Dutch and Portuguese-Jewish background of David Ricardo

This article deals with the Dutch and Portuguese-Jewish background of David Ricardo. The important pieces of information, found in the Amsterdam municipal archives, on the one hand correct, and on the other complement, the data presented by P. Sraffa. Recently, new evidence has been found on Ricardo's stay in Amsterdam in the years 1783?–?85. This evidence throws new light on Ricardo's relationship with his uncle Moses in Amsterdam. It is shown that his formal education was poor, but that his informal education may have been rich. The question of whether Ricardo visited the famous Talmud Tora in Amsterdam is settled in the negative.     

The age of the universal consumer: a reconsideration of Ricardo's politics *

This paper reconsiders Ricardo's political thought, its relationship with his political economy and, more generally, Ricardo's connection with the ‘philosophical radicalism’ of Bentham and James Mill. It is arguedinter alia, that Ricardo's politics were utilitarian and individualistic; that he developed a notion of a shared, homogeneous interest; that he believed that individuals should know their ‘real’ interests as a condition for their suffrage; and that he subscribed to a doctrine of virtual representation. It is also argued that Ricardo was considerably less ‘radical’ in his political views than some previous commentators have recognized.     

Edgeworth's conjecture with infinitely many commodities: commodity differentiation

Summary. Convergence of the cores of finite economies to the set of Walrasian allocations as the number of agents grows has long been taken as one of the basic tests of perfect competition. The present paper examines this test in the most natural model of commodity differentiation: the commodity space is the space of nonnegative measures, endowed with the topology of weak convergence. In Anderson and Zame [12], we gave counterexamples to core convergence in L ¹, a space in which core convergence holds for replica economies and core equivalence holds for continuum economies; in addition, we gave a core convergence theorem under the assumption that traders' utility functions exhibit uniformly vanishing marginal utility at infinity. In this paper, we provide two core convergence results for the commodity differentiation model. A key technical virtue of this space is that relatively large sets (in particular, closed norm-bounded sets) are compact. This permits us to invoke a version of the Shapley-Folkman Theorem for compact subsets of an infinite-dimensional space. We show that, for sufficiently large economies in which endowments come from a norm bounded set, preferences satisfy an equidesirability condition, and either (i) preferences exhibit uniformly bounded marginal rates of substitution or (ii) endowments come from an order-bounded set, core allocations can be approximately decentralized by prices.

OLIGOPOLISTIC PRODUCT WITHHOLDING IN RICARDIAN MARKETS

We consider strategic behaviour in the rental market for quality-differentiated goods. In his classic analysis Ricardo showed that at the competitive equilibrium the price of the marginal unit is driven to zero. An oligopolistic market structure usually leads to a radically different equilibrium. Deliberate withholding of units often becomes part of a firm's best response, and whenever this occurs, a pure strategy equilibrium fails to exist. A necessary but not sufficient condition for a pure strategy equilibrium to exist is for one firm to own all the best quality units. A mixed strategy equilibrium always exists and the associated payoff is aiways greater than the competitive payoff.     

Say's involvement in the 1819 French edition of Ricardo's Principles and the issue of rent

This paper focuses on Say's contribution to the first French edition of Ricardo's Principles and on the analytical consequences of his involvement on the issue of rent. Part one investigates the “story” of this edition. It stresses Say's friendship with the translator, his involvement in this publication and his attitude toward Ricardo. Part two analyses how elements from Say's thought were introduced into Ricardo's theory of rent through this edition. These elements conveyed ideas which were definitely at odds with Ricardo's theory and misrepresented Ricardo's true concept of differential rent which was central to his theory.     

Differential incidence in the presence of initial distorting taxes

This paper extends the two-sector, two-factor, general-equilibrium analysis of differential tax incidence by considering an initial situation where the government finances a fixed commodity bundle by distorting commodity and factor taxes. This alters the traditional analysis of marginal differential incidence in a fundamental way by necessitating the simultaneous determination of the change in the rental-wage ratio, the change in aggregate welfare and the change in an endogenously adjusting tax parameter. This contributes towards an integration of the study of the excess-burden effects and the distributional effects of a given tax situation.
