I let it go out of print because my own views upon its subject had changed so much that I no longer desired to be represented by it. It has, however, been made clear to me that there is still a demand for it; not, I hope, because anyone wants to use the greater part of it as a source of direct instruction, but because there are several parts of it which are still alive in the sense that they provide convenient starting-points for much more modern discussion. References to it have indeed become too frequent for it to be left unavailable. That is the reason why I have finally decided that it ought to appear in a new edition; it also explains why the new edition has had to take so peculiar a form. The change in my own views since 1932 has been too drastic for it to be possible to produce a new edition in the usual way, by changing this and that, and adding extra passages. Besides, it is the old book which is wanted for the purpose mentioned above; so it is this which must be reproduced. I have decided to deal with the situation in the following way. Section I of this new edition is simply a reprint v1 PREFACE TO THE SECOND EDITION of the first edition. Section II, entitled "Documents", includes a couple of articles of my own, written within a few years of the book's first appearance, which serve to illustrate the kinds of change which I felt impelled to make, even in the first stages of further thinking on the subject. To these I have added an important work by another auther. This is the review of my book written in 1933 by Gerald Shove-one of the very small number of published works by that excellent economist. It is included here as a statement (I have come to think it to be a most admirable statement) of the Case for the Prosecution. I am very anxious that any readers (I am afraid there may be some) who even now are tempted to take the 1932 volume too literally should read Shove's criticism. Section III, entitled "Commentary", has been specially written for this new edition. It begins with an introductory section, which attempts to tell the story of the book (its pre-natal as well as its post-natal vicissitudes) in more detail than is appropriate for this preface. I then go through the various chapters, reviewing them (more or less as Shove did) from the standpoint which I would myself take today. There are of course some chapters on which there is little to be said; but there are others (1., VI. and IX.-X. in particular) on which I have had to sketch out a different, and I hope more constructive, treatment. I end with a set of "Notes on the Elasticity of Sub­ stitution", corresponding to the Appendix to the first edition. When I wrote that Appendix, I had no idea of the fruitful use that Mrs. Robinson was so PREFACE TO THE SECOND EDITION vn soon to make of what proved to be identically the same concept. Professor Lerner's simple proof of the "relative shares" proposition, proceeding from Mrs. Robinson's definition, is given in the "Revised Version" paper which appears in Section II; other ways in which my treatment could have been clarified by that alternative approach did not appear until much later.

S.

It is thus an undertaking which seems to need little apology. Periodical reconsiderations of each of the main departments of economic theory are an important part of the duty of economists; since, for one thing, one field is often illuminated by advances which have been made in others, and for another, the events of con­ temporary history make it necessary to examine possibilities, of which earlier writers may have been aware, but which they naturally regarded as not worthy of special attention. Such a reconsideration of wage theory seems long overdue. For the most recent comprehensive statements of a positive theory of wages in English-<>£ anything more than an elementary character-are now thirty or forty years old. We have to go back for them to Marshall's Principles and Clark's Distribution of Wealth. Since that time important work on the subject has indeed been done, but it is nearly all special studies; even Professor Pigou's treatment of Labour, in the Economics of Welfare, ought probably so to be reckoned for our purposes. Of these works much use has been made in the following pages: to them lX x PHEFACE TO THE FIHST EDITION this book owes a great debt; but they have notre­ moved the need for some undertaking like the present. The historical fact which dominates the wage­ history of the present century-both in Britain and in other countries-is the growth of Trade Union power and the development of State Regulation of Wages. This fact, which is due to a complex of causes, and which could not have been wholly foreseen by econo­ mists thirty years ago, alters very considerably the range of problems with which we have to deal. It might even appear at first sight as if it ought to change the whole structure of our theory-that we ought to treat the regulation of wages as the normal case, and take its consideration first. But this course does not prove satisfactory. The same forces which determine wages in a free market are still present under regula­ tion; they only work rather differently. It is therefore best for us to begin in the traditional manner with the determination of wages under competition; though at a later stage we must examine regulation in more detail than the traditional theories do. By proceeding in this way, we secure the great advantage of being able to build directly upon familiar doctrines; and we naturally start with a consideration of that principle which was regarded by the economists of Marshall's generation as the basis of their theory of wages-the principle of Marginal Productivity. The validity and the importance of this principle we shall see no reason to question; but its very importance has one awkward consequence. For we shall get into end­ less difficulties if we allow any obscurity about so PREFACE TO THE FIRST EDITION xi essential a principle to persist; and it is unfortunately the case that its original propounders did leave it-or at least its application-in some obscurity. We are therefore faced at the start with the hard task of trying to make clear something which Marshall and J. B. Clark did not make altogether clear; and we cannot hope to do this if we shirk difficulties. The reader must therefore be asked to follow Chapter I. with attention and some patience; but he may be assured that rela­ tively smooth waters lie beyond. One very important aspect of the theory of wages it has unfortunately been necessary to leave undiscussed -the relation of wages to general industrial fluctua­ tions or trade cycles. In this branch of economics recent years have certainly seen striking advances; it does seem probable that in a few years' time we shall possess the main lines of an established theory of fluctuations; but that time is not yet. Thus to discuss trade fluctuations from any angle is hazardous, since nothing useful can be said unless one is prepared to take sides on the critical issues. And most of these lie altogether outside the theory of wages, although they have a direct bearing upon it. Thus I must confine myself here to stating a personal opinion. It is my own belief that some parts of this book-particularly the last chapters-have considerable relevance to the theory of fluctuations, although they are not stated with that particular reference.

  • Measuring the Bias of Technological Change*
    Measuring the Bias of Technological Change∗ Ulrich Doraszelski† Jordi Jaumandreu‡ University of Pennsylvania and CEPR Boston University and CEPR This version: February 2009 New version coming soon: January 2012. Abstract When technological change occurs, it can increase the productivity of capital, labor, and the other factors of production in equal terms or it can be biased towards a specific factor. Whether technological change favors some factors of production over others is an empirical question that is central to economics. The literatures in industrial organization, productivity, and economic growth rest on very specific assumptions about the bias of technological change. Yet, the evidence is sparse. In this paper we propose a general framework for estimating production functions. Using firm-level panel data, we are able to directly assess the bias of technological change by measuring, at the level of the individual firm, how much of technological change is factor neutral and how much of it is labor augmenting. We further relate the speed and the direction of technological change to firms’ R&D activities. ∗We thank Pol Antràs, Matthias Doepke, Michaela Draganska, Chad Jones, Dale Jorgenson, Larry Katz, Pete Klenow, Zhongjun Qu, Matthias Schündeln, and John Van Reenen for helpful discussions.

  • Marx on Absolute and Relative Wages
    Munich Personal RePEc Archive Marx on absolute and relative wages Levrero, Enrico Sergio Roma Tre University, Department of Economics September 2009 Online at https://mpra.ub.uni-muenchen.de/20976/ MPRA Paper No. 20976, posted 26 Feb 2010 06:51 UTC Marx on absolute and relative wages Enrico Sergio Levrero, Department of Economics, Roma Tre University∗ Introduction 1. The aim of this paper is to clarify some aspects of Marx’s analysis of the determinants of wages and of the peculiarity of labour as a commodity, concentrating upon three related issues. The first is that of Marx’s notion of the subsistence (or natural) wage rate: subsistence wage will be shown to stem, according to Marx, from socially determined conditions of reproduction of an efficient labouring class. The second issue refers to the distinction between the natural and the market wage rate that can be found in Marx, and his critique of Ricardo’s analysis of the determinants of the price of labour. Here the “law of population peculiar to capitalist mode of production” (that is, Marx’s industrial reserve army mechanism) will be considered, both with respect to cyclical fluctuations of wages and to their trend over time. Moreover, a classification of the social and institutional factors affecting the average wage rate will be advanced. Finally, Marx’s analysis of the effects of technical progress on both absolute and relative wages will be considered, also relating it back to the long-standing debate on the Marxian law of the falling rate of profit, and addressing some possible scenarios of the trend of wages and distribution.

The paper aims to address a neglected and controversial theoretical argument on neutral technical progress related to the measure of value that preceded and then continued to the period of the Cambridge Capital Theory Controversy. I focus on Kennedy's writings and his solutions to the complications between the measure of value and technical progress. Important intuitions behind the measure of value are crucial to the formulation of neutral technical progress in both the post-Keynesian and the neoclassical-Keynesian endogenous growth models. The paper concludes with mathematical illustrations of neutral technical progress theories.

  • John Bates Clark As a Pioneering Neoclassical Economist Thomas C
    “A Certain Rude Honesty”: John Bates Clark as a Pioneering Neoclassical Economist Thomas C. Leonard John Bates Clark (1847–1938), the most eminent American economist of a century ago, was, in his own day, caricatured as an apologist for laissez-faire capitalism (Veblen 1908).1 The caricature has shown stay- ing power, a measure, perhaps, of the relative paucity of scholarship on Clark and his work. Recent Clark research signals a welcome attempt at a more accurate portrait (Morgan 1994; Henry 1995; Persky 2000). But some revisionists would remake Clark the apologist for capital into Clark the Progressive exemplar. Robert Prasch (1998, 2000), for exam- ple, depicts Clark as a Progressive paragon, which groups him with the greatreformers of Progressive-Era politicaleconomy—Social Gospel- ers such as Richard T. Ely and his protégé John R. Commons, labor leg- islation activists such as Clark’s junior colleague Henry Rogers Seager Correspondence may be addressed to Thomas C.

Lawrence NBER Working Paper No. 21296 June 2015 JEL No. D3,D33 ABSTRACT As shown in the 1930s by Hicks and Robinson the elasticity of substitution (σ) is a key parameter that captures whether capital and labor are gross complements or substitutes. Establishing the magnitude of σ is vital, not only for explaining changes in the distribution of income between factors but also for undertaking policy measures to influence it. Several papers have explained the recent decline in labor’s share in income by claiming that σ is greater than one and that there has been capital deepening.

    Measuring the Bias of Technological Change∗ Ulrich Doraszelski† Jordi Jaumandreu‡ University of Pennsylvania Boston University This draft: March 19, 2015 First draft: December 13, 2008 Abstract Technological change can increase the productivity of the various factors of produc- tion in equal terms or it can be biased towards a specific factor. We directly assess the bias of technological change by measuring, at the level of the individual firm, how much of it is labor augmenting and how much is factor neutral. To do so, we develop a framework for estimating production functions when productivity is multi-dimensional. Using panel data from Spain, we find that technological change is biased, with both its labor-augmenting and its factor-neutral component causing output to grow by about 2% per year. ∗We thank Pol Antr`as, Matthias Doepke, Michaela Draganska, Jos´eCarlos Fari˜nas, Ivan Fernandez-Val, Paul Grieco, Chad Jones, Dale Jorgenson, Larry Katz, Pete Klenow, Jacques Mairesse, Ariel Pakes, Amil Petrin, Zhongjun Qu, Devesh Raval, Juan Sanchis, Matthias Sch¨undeln, and John Van Reenen for helpful discussions and Sterling Horne, Mosha Huang, Thomas O’Malley, and Dan Sacks for research assistance.

  • Algebraic Production Functions and Their Uses Before Cobb-Douglas
    Algebraic Production Functions and Their Uses Before Cobb-Douglas Thomas M. Humphrey undamental to economic analysis is the idea of a production function. It and its allied concept, the utility function, form the twin pillars of F neoclassical economics. Written P = f(L, C, T . .), the production function relates total product P to the labor L, capital C, land T (terrain), and other inputs that combine to produce it. The function expresses a technological relationship. It describes the maximum output obtainable, at the existing state of technological knowledge, from given amounts of factor inputs. Put differently, a production function is simply a set of recipes or techniques for combining inputs to produce output. Only efficient techniques qualify for inclusion in the function, however, namely those yielding maximum output from any given combination of inputs. Production functions apply at the level of the individual firm and the macro economy at large. At the micro level, economists use production functions to generate cost functions and input demand schedules for the firm. The famous profit-maximizing conditions of optimal factor hire derive from such micro- economic functions. At the level of the macro economy, analysts use aggregate production functions to explain the determination of factor income shares and to specify the relative contributions of technological progress and expansion of factor supplies to economic growth. For valuable comments on earlier drafts of this article, the author is indebted to his Richmond Fed colleagues Bob Hetzel, Ned Prescott, Pierre-Daniel Sarte, and Alex Wolman.

    EQUILIBRIUM IN THE LABOUR MARKET WITH SEARCH FRICTIONS Prize Lecture, December 8, 2010 by CHRISTOPHER A. PISSARIDES1 London School of Economics, UK. Research in the economics of the labour market when there are search frictions started in the 1960s, with influential contributions from George Stigler (1962), John McCall (1970) and the papers collected in Edmund Phelps et al. (1970). Of course, as is common in economics, this was not the first time that economists took seriously the role of search frictions in their research. Insightful discussions of the role of frictions in labour mar- ket equilibrium can be found much earlier, in books by John Hicks (1932) and William Hutt (1939). But it was not until the late 1960s that formal mathematical models of individual behaviour and labour market equilibrium appeared. The development of formal mathematical models with search frictions coincided with the time that I was looking for a topic for my PhD research.2 Two things about search impressed me most. In the Phelps volume, search was claimed as a microfoundation for the natural rate of unemployment, in- troduced just a year or two before by Milton Friedman (1968) and Edmund Phelps (1967), and for the inflation-unemployment trade-off (the Phillips curve). It was also claimed, by Axel Leijonhufvud (1968) in particular, that it could provide a microfoundation for Keynes’s concept of effective demand: the idea was that the job seeker could make her demand for goods effective only after she succeeded in locating a mutually acceptable job match. The articles in the Phelps volume, however, especially those by Phelps (1970) and Dale Mortensen (1970) which had explicit models of the Phillips curve, required a wage distribution to obtain the microfoundations of the Phillips curve.

  • What Determines the Direction of Technological Progress?* Defu Li1
    What Determines the Direction of Technological Progress? Defu Li1 School of Economics and Management, Tongji University Benjamin Bental2 Department of Economics, University of Haifa Abstract What determines the direction of technological progress is one of the central questions that economics needs to answer. The current paper tries to answer this question by introducing a small but fundamental generalization of Acemolgu (2002). The extended model argues that although changing relative factor prices (as suggested by Hicks 1932) and the relative market size (as argued by Acemoglu 2002) indeed affect the direction of technological progress in the short run, in the long run that direction depends only on the relative supply elasticities of primary factors with respect to their prices. Moreover, it is biased towards enhancing the effectiveness of the factor with the relatively smaller elasticity. The troubling property of the neoclassical growth model discovered by Uzawa (1961), whereby balanced growth is reconcilable only with purely labor augmenting technological progress, is due solely to an implicit assumption that the capital supply elasticity is infinite. Key Words: direction of technological progress, steady-state, Uzawa’s theorem, investment elasticities, factor supply elasticities.
