4、,Carl Menger,Neo Classicals,John Hicks,David Ricardo,Joseph Schumpeter,According to Smith,Saving is necessary for the achievement of economic growth. The earning of profit is consequent, not simply upon the accumulation of capital, but, significantly, also upon the fruits of the division of labor in

5、 modern terms capital accumulation, technical progress and economic organization are tied together. The availability of capital is necessary (though apparently not sufficient) for the adoption of new and more productive methods of production. There is a type of diminishing returnsthis is clearly not

6、 in the form of a declining rate of return to investment in a given mode of production, but rather refers to the eventual possible exhaustion of investment opportunities for extending the division of labor, that is, for the discovery and introduction of new and improved production methods.,David Ric

8、 marginalist revolution. Labor value was replaced by equilibrium value (general equilibrium).,Carl Menger,Owes much to Adam Smith and nothing to Ricardo. There is a time structure to the production process. Goods of lower and higher order. The earlier one intervenes in natures processes the more pro

9、ductive one can be. “By making progress in the employment of goods of higher orders for the satisfaction of their needs, economizing men can most assuredly increase the consumption goods available to them accordingly - but only on condition that they lengthen the periods of time over which their act

10、ivity is to extend in the same degree that they progress to goods of higher order.” (Menger 1981: 153 italics added). Production is the result of human planning - there can be errors - the market tends to correct such errors, but there is no continual equilibrium - there is continual groping of the

11、structure of production toward the changing structure of consumption.,Underlining Mengers Insights,Adopting Mengers perspective one cannot lose sight of the variety of goods and services and individual activities and choices. There is no suggestion of a uniform rate of profit at any point in time. Y

12、et there is an inescapable order within the variety provided by our understanding of the purposes of individuals. “The process of transforming goods of higher order into goods of lower order, . must always be planned and conducted, with some economic purpose in view, by an economizing individual” (M

13、enger 1981: 159-60). Capital and the conscious organization of production are inextricably linked.,Eugene von Bhm-Bawerk,The most visible and well known Austrian economist the “master” of Austrian Capital Theory 3 volumes over many years, engaging many eminent scholars B-Bs vision is the same as Men

14、gers a series of concentric circles wisely chosen “roundabout” methods of production are more “productive” they yield a greater volume of consumption goods.,Roundabout Production is Advantageous,“There are two concomitants of the adoption of the capitalist methods of production, . One is advantageou

15、s, the other disadvantageous. . With an equal expenditure of the two originary productive forces, labor and valuable forces of nature, it is possible by well chosen roundabout capitalist methods to produce more or better goods than would have been possible by the direct noncapitalist method. It is a

16、 truism well corroborated by empirical evidence.” (Bhm-Bawerk 1959: Book II, 82-3).“.One thing that can be stated with a reasonable degree of certainty is the proposition . that as a general rule a wisely selected extension of the roundabout way of production does result in an increase in the magnit

17、ude of the product. It can be confidently maintained that there is no area of production which could not materially increase its product over the result obtained by its present method (Bhm-Bawerk.” 1959: 84-85).,But a Sacrifice is Involved,“The disadvantage which attends the capitalist method of pro

18、duction consists in a sacrifice of time. Capitalist roundaboutness is productive but time-consuming. It yields better consumption goods, but not until a later time.” (Bhm-Bawerk 1959: 82).“All consumption goods which man produces come into existence through the cooperation of human powers with the f

19、orces of nature, which are in part of economic character, in part free natural powers. Man can produce the consumption goods he desires through those elemental productive powers. He does so either directly, or indirectly through the agency of intermediate products which are called capital goods. The

20、 indirect method entails a sacrifice of time but gains the advantage of an increase in the quantity of the product. Successive prolongations of the roundabout method of production yield further quantitative increases though in diminishing proportions.” (Bhm-Bawerk 1959: 88).,Structure or Quantity? M

21、enger or Ricardo?,He believes in structure: “A nations capital is the sum of heterogeneous concrete capital goods. To aggregate them one needs a common denominator. This common denominator cannot be found in the number of capital goods nor their length or width or volume or weight or any other physi

22、cal unit of measurement . The only measuring rod that does not lead to contradictions is the value of these capital goods” (Hennings 1997: 132, his translation of Bhm-Bawerk 1959 1921 III 105). He provides a formal quantitative treatment: “It is more important, as well as correct, to consider the av

23、erage time interval occurring between each expenditure of originary productive forces and the final completion of the ultimate consumption good. A production method evinces a higher or lower degree of capitalist character, according to whether, on the average, there is a longer or shorter period of

24、waiting for the remuneration of the expenditure of the originary productive forces, labor and uses of land.” (Bhm-Bawerk 1959: 86).

29、chmann and Beyond.,Hayek is of the “compositive” school Hayek at the LSE contra Keynes needed a more complete theory of Capital The Pure Theory of Capital 1941 “Our main concern will be to discuss in general terms what type of equipment it will be most profitable to create under various conditions,

30、and how the equipment existing at any moment will be used, rather than explain the factors which determined the value of a given stock of production equipment and the income that will be derived from it.” (1941: 3) “The problems that are raised by any attempt to analyze the dynamics of production ar

But all the essential differences between these parts were obscured by the general endeavor to subsume them under one compreh

The fact that this stock of capital is not an amorphous mass but possesses a definite structure, that it is organized in a definite way, and that its composition of essentially different items is much more important than its aggregate quantity, was systemat

33、ically disregarded.” (1941: 6).,Lachmann extends the “compositive” vision,Hayek never managed to produce a treatment of Capital that satisfied him Investment that raises the demand for Capital (1937) is the inspiration for Lachmanns work on Capital 1956 Capital and Its Structure the final chapter?,L

34、achmann - Aspects of the Capital Structure,Capital is Heterogeneous capital vs. capital goods. Capital goods are part of the Capital Structure. A “structure” is an order. The capital structure is partly designed and partly the result of adaptation “spontaneous order.” The design part is about firms

35、(and households) The spontaneous part is about the market process The capital structure is characterized by complementarity and specificity. Decision-makers form capital combinations with complementary resources some are dynamically more specific than others Change cause substitutions to be made - c

37、 the economic organization. Hayek Richardson, Penrose and recent work on firm boundaries and strategies (linking up with Coase and Williamson). When does aggregation (quantity) obscure structure? When incommensurate items are aggregated. Modularity may be the way to go. Organization matters for prod

What viewpoint is more relevant to the real world in which interest is paid in money?,Implications of PTPT,Interest is not profit! Profit is the result of uncertainty (Kn

40、ight, Mises, Hayek, Rothbard). Resource owners earn rent (Rothbard, Fetter) - wages (human capital), rent (land and physical capital) - all resources are part of “capital” - also relevant to the economics of organization. The level of interest rates has very little to do with economic growth and productivity. Directs our attention to the market for loanable funds.,
