"If you want to do good research, it's important not to know too much. This almost sounds contradictory but really if you know too much and you get an idea, you will sort of talk yourself out of trying it because you figure it won't work. But if you know just the right amount and you get enthusiastic about your project, you go ahead, you do it and if you're lucky things'll work out."
"The facts are that in the last 100 years we have measured the temperatures it has gone up .8 degrees and everything in the world has gotten better."
"How can you possibly measure the average temperature for the whole earth and come up with a fraction of a degree?"
"They can fiddle with the data. That is what NASA does."
"Global warming really has become a new religion. Because you cannot discuss it. It’s not proper. It is like the Catholic Church."
"I would say that the global warming is basically a non-problem. Just leave it alone and it will take care of itself."
"For the last hundred years, the ocean has risen 20 cm — but for the previous hundred years the ocean also has risen 20 cm and for the last 300 years, the ocean has also risen 20 cm per 100 years. So there is no unusual rise in sea level. And to be sure you understand that I will repeat it. There is no unusual rise in sea level."
"I am not really terribly interested in global warming. Like most physicists I don't think much about it. But in 2008 I was in a panel here about global warming and I had to learn something about it. And I spent a day or so — half a day maybe on Google, and I was horrified by what I learned."
"When the ice age comes, the temperature falls 8 degrees. So maybe we should pollute more, to prevent that?"
"What is the the correct temperature? It would be a miracle if the correct temperature for the world is the temperature we have today. Clearly that is not true. Maybe we’d be better off 2 degrees warmer. Maybe we’d be better off 2 degrees colder. I don’t know, but what I do know is this is not the correct temperature."
"To me the greatest moment in an experiment is always just before I learn whether the particular idea is a good or a bad one. Thus even a failure is exciting, and most of my ideas have of course been wrong. But this time it worked!"
"If I have learned anything as a scientist it is that one should not make things complicated when a simple explanation will do."
"My own beliefs are that the road to a scientific discovery is seldom direct, and that it does not necessarily require great expertise. In fact, I am convinced that often a newcomer to a field has a great advantage because he is ignorant and does not know all the complicated reasons why a particular experiment should not be attempted."
"While Giaever is certainly a highly accomplished physicist, that does not automatically make him a climate expert as well. As Giaever himself has admitted, he has spent very little time researching the subject, and it shows. He simply bounces from one climate myth to the next, demonstrating a lack of understanding of Climate Science 101, and then insults the entire scientific field by comparing it to a religion."
"Intermediate between mathematics, statistics, and economics, we find a new discipline which, for lack of a better name, may be called econometrics. Econometrics has as its aim to subject abstract laws of theoretical political economy or "pure" economics to experimental and numerical verification, and thus to turn pure economics, as far as possible, into a science in the strict sense of the word."
"I believe that economic theory has arrived at a point in its development where the appeal to quantitative empirical data has become more necessary than ever. At the same time its analyses have reached a degree of complexity that require the application of a more refined scientific method than that employed by the classical economists."
"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."
"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"
"In the last decade's intensive study of all sorts of social and economic time series, it has become clear, it seems to me, that the usual time series technique is not quite adequate for the purpose which the social investigator is pursuing... We want to find out on more or less empirical grounds what is actually present in the series at hand, that is to say, what sort of components the series contains."
"I approached the problem of utility measurement in 1923 during a stay in Paris. There were three objects I had in view :"
"Econometrics is by no means the same as economic statistics. Nor is it identical with what we call general economic theory, although a considerable portion of this theory has a definitely quantitative character. Nor should econometrics be taken as synonymous with the application of mathematics to economics. Experience has shown that each of these three view-points, that of statistics, economic theory, and mathematics, is a necessary, but not by itself a sufficient, condition for a real understanding of the quantitative relations in modern economic life. It is the unification of all three that is powerful. And it is this unification that constitutes econometrics."
"The majority of the economic oscillations which we encounter seem to be explained most plausibly as free oscillations."
"[The] length of the cycles and the tendency towards dampening are determined by the intrinsic structure of the swinging system, while the intensity (the amplitude) of the fluctuations is determined primarily by the exterior impulse. An important consequence of this is that a more or less regular fluctuation may be be produced by a cause which operates irregularly."
"The propagation problem is the problem of explaining by the structural properties of the swinging system what the character of the swings would be in case the system was started in some initial situation"
"When we approach the study of business cycle with the intention of carrying through an analysis that is truly dynamic and determinate in the above sense, we are naturally led to distinguish between two types of analyses: the micro-dynamic and the macro-dynamic types. The micro-dynamic analysis is an analysis by which we try to explain in some detail the behaviour of a certain section of the huge economic mechanism, taking for granted that certain general parameters are given. Obviously it may well be that we obtain more or less cyclical fluctuations in such sub-systems, even though the general parameters are given. The essence of this type of analysis is to show the details of the evolution of a given specific market, the behaviour of a given type of consumers, and so on."
"There is also present another source of energy operating in a more continuous fashion and being more intimately connected with the permanent evolution in human societies."
"Certain exterior impulses hit the economic mechanism and thereby initiate more or less regular oscillations."
"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."
"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."
"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."
"At present the national budget plays a very large role in the whole financial policy of our country."
"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."
"Usually it is easier to obtain estimates for budget proportions and Engel elasticities than for elasticities with respect to price. By making certain want independence assumptions, the elasticities with respect to price can be deduced from the knowledge of budget proportions and Engel elasticities. In this connection the concept of the flexibility of the marginal utility of money is essential. A system of formulae decribing these relations is given."
"To proceed from assumptions about an abstract theoretical set-up and from them to draw conclusions about the observable world and to test - by rough or more refined means - whether the conformity with observations is "good" enough, is indeed the time honoured procedure that all empirical sciences, including the natural sciences, have used. I shall therefore not plead guilty of heresy even if I do work with choice-theory concepts that are not invariant under a general monotonic transformation of the utility indicator."
"In this feverish world of ours, where one wants the economic analyses to produce easily understandable results quickly and at the least possible cost, some of us have fallen into the habit of assuming for simplicity that the hundreds sometimes thousands of variables that enter into the analyses are linked together by very simple relationships. Frequently we even go so far as to assume linear relationships. Only in this way have we been able to feed our problems into the electronic computers and get mechanical answers quickly and at low cost."
"Questions of convergence under an infinite time horizon will depend so much on epsilontic refinements in the system of assumptions — and on the infinite constancy of these refinements — that we are humanly speaking absolutely certain of getting infinite time horizon results which have no relevance to concrete reality. And in particular we are absolutely certain of getting irrelevant results if such epsilontic exercises are made under the assumption of a constant technology. 'In the long run we are all dead.' These words by Keynes ought to be engraved in marble and put on the desk of all epsilontologists, in growth theory under an infinite horizon."
"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."
"(Econometrics is) the unification of economic theory, statistics and mathematics."
"In this essay on econometrics in its conception and its use in economic planning for the betterment of man’s fate, I will try to cover a very broad field. When talking about the methodology in the particular fields mentioned - about which I am supposed to have a little more than second hand knowledge - I have always found it utterly inadequate to focus attention only on these special fields without seeing them in a much broader perspective. Therefore it was inevitable that I should have to include in the field of vision of this paper also some branches of science where I can only speak as a layman, hopefully as a somewhat informed layman. For whatever blunders I may have made in these fields I must ask for the reader’s forgiveness"
"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."
"… in economic political discussions there is a nearly infinite number of specific questions that may be asked. Besides the ones mentioned in section 3 consider for instance these: "Should we build a road between points A and B in the country?", "Should we promote investments that will give employment to many people, or should we on the contrary promote such investment which will save labour?"… "Should we put more emphasis on things that have up to now not been included in the statistical concept of the gross national product? For instance, should we try to avoid air-pollution and all the kinds of intoxications that may be caused by refuse and waste (a problem that must be studied in its totality as a problem of circulation of matter in society, much in the same way as we study interindustry relations in an input-output table)?“, “Should we assess economic value to an undisturbed nature?” etc."
"Ragnar Frisch was an ardent protagonist for more scientific economics in the interwar period and played an active role internationally through his scholarly contributions but also through his efforts for the and its journal , which may be regarded as landmarks both for the scientification and the internationalization of economics. For many years Frisch was the only Norwegian economist of international renown and became a father figure for Norwegian economics."
"What makes a piece of mathematical economics not only mathematics but also economics is, I believe, this: When we set up a system of theoretical relationships and use economic names for the otherwise purely theoretical variables involved, we have in mind some actual experiment, or some design of an experiment, which we could at least imagine arranging, in order to measure those quantities in real economic life that we think might obey the laws imposed on their theoretical namesakes."
"Haavelmo was the first to recognize the capacity of economic models to guide policies. This paper describes some of the barriers that Haavelmo’s ideas have had (and still have) to overcome, and lays out a logical framework that has evolved from Haavelmo’s insight and matured into a coherent and comprehensive account of the relationships between theory, data and policy questions. The mathematical tools that emerge from this framework now enable investigators to answer complex policy and counterfactual questions using simple routines, some by mere inspection of the model’s structure."
"When I was a boy, I was not a believer at first, not yet, but then I changed my outlook and with it my writing also changed. When I start working, I start from scratch, I don't document or prepare myself by doing research, but I try to turn what I am doing into something else. For me, writing is listening and for me to find it interesting it must be a new experience every single time. It is my desire to createsomething that was not yet there."
"I wrote my first novel when I was 20, I am now 65, so I have been practising this exercise of creation for a very long time, but the exciting aspect of writing always remains the act itself. It is not re-reading the work, which counts, but the journey into the unknown.Suddenly I get the feeling that what I am writing is already ready somewhere, outside of me, and I am left only with the task of putting it on the page before it disappears. For an atheist such as I was, understanding this and trying to explain it meant admitting that there are invisible things. It was by acknowledging this reality that I began to believe in something I did not believe in: the existence of God."
"God is three in one, something that is impossible to explain. [...] For a while I attended Quakers: no sacraments, no formal dogma. There was a prayer room, furnished in the simplest way, and we sat there in a silent circle, seeking the inner light. What I call God and what is in each of us says something to each of us. These are extreme forms of mysticism and spirituality belonging to the Protestant root, but even starting from these positions one still ends up encountering the mystery of faith. A mystery that unites Quaker and Catholic religion, to which I have since converted."
