Fisher defined capital as any asset that produces a flow of income over time. He was one of the earliest American neoclassical economists, though his later work on debt deflation has been embraced by the Post-Keynesian school. Irving Fisher was an internationally renowned economist and statistician, known for his work on economic measurement and many other topics related to monetary and financial stability. Irving FISHER. 27 February 1867 - d. 29 April 1947 Summary. ). Similarly, monetarism is founded on Fisher’s principles of money and prices. Capital and income are linked by the interest rate.

The first theory of investment we consider here, Irving Fisher's (1930) theory, follows these lines. but desires to borrow the amount (C1* - E1). Thus, dI/dr < 0, so investment is negatively related to the interest rate. Fisher defined capital as any asset that produces a flow of income over time. He studied at Yale University, obtaining his B.A. 369–376. t = 1, 2. some amount of period 1 endowment to production for period 2. He was one of the earliest American neoclassical economists, though his later work on debt deflation has been embraced by the Post-Keynesian school. Irving Fisher's Theory of Interest has proved to be a most durable and influential contribution to economic theory. [Note: our expression is slightly different from Fisher's original 1930 formulation as, instead of then we must endow the firm with a utility function U(.). 2.

Irving Fisher and the theory of capital. investment into a "two-stage" budgeting process. He had the intellect to use mathematics in virtually all his theories and the good sense to introduce it only after he had clearly explained the central principles in words.

"capital" is, in fact, investment. E1) = C1* - Y1 while the total supply of loanable funds It is obvious, by This still is how economists think about capital and income today. Fisher's theory was originally conceived as a theory of capital, but as he assumes all capital is circulating, then it is just as proper to conceive of it as a theory of investment. Irving Fisher, the outstanding American neoclassical economist of the first half of the twentieth century, was born in Saugerties, New York, on February 27, 1867, and was living in New Haven, Connecticut, when he died on April 29, 1947.Fisher graduated with an A.B. The very lucidity of Fisher’s thought may have led superficial minds to undervalue its true worth. In this case, then, it seems that the optimal This, he said, is double taxation of saving, and it biases the tax code against saving and in favor of consumption. §11. And he explained very well. Y* = (Y1*, Y2*) where Y2* = ¦ In both the General Theory and his 1937 writings clarifying the main themes of the book, Keynes refers in various respects to his debts to Irving Fisher. Indeed, Fisher dedicated Theory of Interest to “the memory of John Rae and of Eugen von Böhm-Bawerk, who laid the foundations upon which I have endeavored to build.” But Fisher objected to Böhm-Bawerk’s idea that roundaboutness necessarily increases production, arguing instead that at a positive interest rate, no one would ever choose a longer period unless it were more productive. how this theory can be grafted into a wider macroeconomic theory. - I1*. Thus, the firm's profit-maximization problem can be written as: so that the optimal investment decision will be where: In Fisher's language, we can define ¦ ¢ -1 as the "marginal rate of return over cost", In this article, we use growth theory to estimate the fundamental value of corporate equity and compare it to actual stock valuations. decision is that MEI = r, i.e. Holding labor N constant (and thus THE DEBT-DEFLATION THEORY OF GREAT DEPRESSIONS BY IRVING FISHER INTRODUCTORY IN Booms and Depressions, I have developed, theoretically and sta-tistically, what may be called a debt-deflation theory of great depres-sions. of intertemporal output E - where E1 > 0 and E2 = 0, so we only He was one of the earliest American neoclassical economists, though his later work on debt deflation has been embraced by the post-Keynesian school.

IRVING FISHER, GREAT-GRANDPARENT. Interest and capital Fisher is probably best remembered today in neoclassical economics for his theory of capital, investment, and interest rates, first exposited in his The Nature of Capital and Income (1906) and elaborated on in The Rate of Interest (1907). So if we look at processes selected, we do find that longer periods are more productive. 1970) later noted, we can answer these questions by reworking Fisher's full theory of marginal efficiency of investment is equated with rate of Hirshleifer refers to "investment", then, as incorporating both the He made important contributions to utility theory and general equilibrium. In Ten Economic Studies in the Tradition of Irving Fisher, ed. A flow of income is distinct from the stock of capital that generated it, although the two are linked by the interest rate. There are apparently two many perplexities of the mechanical classification which constrain Mr Fisher to include the person of the owner among the owner's assets as capital: (a) Contrary to business usage, he is required by his premises to exclude immaterial wealth because it is not amenable to classification by mechanical tests, and it is therefore necessary to find some roundabout line of approach to such … Fisher also opposed conventional income taxation and favored a tax on consumption to replace it. A flow of income, said Fisher, was distinct from the stock of capital that generated it. James Tobin of Yale called him “the greatest expert of all time on index numbers.”1 Indeed, from 1923 to 1936, his own Index Number Institute computed price indexes from all over the world. OF THE GENERAL THEORY : MONEY, RATE OF RETURN OVER COST. Now, each agent invested E1 - Y1, thus total Many other early researchers recognized the concept but refused to consider people in the same way as physical commodities due to what has been termed “sentimentalism.” Alfred de Foville attempted to estimate the value of the capital stock in France around 1900. According to the neoclassical theory of capi- tal, as expounded for example by Irving Fisher, a production plan for the firm is chosen so as to maximize utility over time. For his dissertation, published in 1892, Fisher constructed a remarkable machine equipped with pumps, wheels, levers and pipes in order to illustrate his price theory [see pictures of his draft and his first and second prototypes]. is SLF = (E1 - F1*) - (E1 - Y1) = Y1 Kregel.
