Ragnar Frisch Quotes

In reality the cycles we have the occasion to observe are generally not damped. How can the maintenance of the swings be explained? Have theses dynamic laws deduced from theory and showing damped oscillations no value in explaining the real phenomena, or in what respect do the dynamic laws need to be completed in order to explain the real happenings? They (dynamic laws) only form one element of the explanation: they solve the propagation problem. But the impulse problem remains.

Personally, I never met . I saw him once when he delivered a lecture in Oslo, but being an unassuming student at the time, I did not have the courage to talk to him. So my knowledge of his theory came only through his writings. That, however, was a very intense and absorbing form of making his acquaintance. Already from my early student days, I read his writings (in German and Swedish) avidly. And I continued to do so later. When I started my study on Wicksell, I found that his works were not easy reading. Often it was only at the third or fourth reading that I grasped his ideas. Invariably, each new reading made me more and more enthusiastic. Sometimes it happened that I thought I had finally caught him in an inconsistency or in unclear thinking. Every time this happened, it turned out, however, that the error was mine.

We may perhaps start by throwing all kinds of production into one variable, all consumption into another, and so on, imagining that the notions 'production', 'consumption', and so on, can be measured by some sort of total indices. At present certain examples of micro-dynamic analyses have been worked out, but as far as I know no determinate macro-dynamic analysis is yet to be found in the literature.

I have insisted that econometrics must have relevance to concrete realities, otherwise it degenerates into something which is not worthy of the name econometrics, but ought rather to be called playometrics.

Two important features in the modern development of economics are the application of mathematics to abstract economic reasoning... and the attempt at placing economics on a numerical and experimental basis by an intensive study of economic statistics.

Original in French: Intermediaire entre les mathematiques, la statistique et l'economie politique, nous trouvons une discipline nouvelle que ion peut, faute de mieux, designer sous le nom de reconometrie. L'econometrie se pose le but de soumettre les lois abstraites de l'economie politique theorique ou l'economie 'pure' A une verification experimentale et numeriques, et ainsi de constituer, autant que cela est possible, l'economie pure en une science dans le sens restreint de ce mot.

(Econometrics is) the unification of economic theory, statistics and mathematics.

An important object of the Journal should be the publication of papers dealing with attempts at statistical verification of the laws of economic theory, and further the publication of papers dealing with the purely abstract problems of quantitative economics, such as problems in the quantitative definition of the fundamental concepts of economics and problems in the theory of economic equilibrium. The term equilibrium theory is here interpreted as including both the classical equilibrium theory proceeding on the lines of Walras, Pareto, and Marshall, and the more general equilibrium theory which is now beginning to grow out of the classical equilibrium theory, partly through the influence of the modern study of economic statistics. Taken in this broad sense the equilibrium problems include virtually all those fundamental problems of production, circulation, distribution and consumption, which can be made the object of a quantitative study. More precisely: The equilibrium theory in the sense here used is a body of doctrines that treats all these problems from a certain point of view, which is contrasted on one side with the verbal treatment of economic problems and on the other side with the purely empirical-statistical approach to economic problems

We may predict that the science of which we try to be the humble and devoted servants will in the future life of the nations be an important factor in eliminating maladjustments between fundamental economic sectors and assure a smooth and progressive utilization of resources... One wants men with a knowledge of the characteristic features of the economic and social structure of their country and with a fundamental theoretical knowledge along modern lines.

I approached the problem of utility measurement in 1923 during a stay in Paris. There were three objects I had in view :

Deep in the human nature there is an almost irresistible tendency to concentrate physical and mental energy on attempts at solving problems that seem to be unsolvable.

Certain exterior impulses hit the economic mechanism and thereby initiate more or less regular oscillations.
