“Economics is a young science, and there is still much to be learned. Economists sometimes disagree because they have different hunches about the validity of alternative theories or about the size of important parameters that measure how economic variables are related.”

“The usefulness of observation and measurement in testing economic theories arises because the theorems of economics are supposed to relate to the actual world… Any economic theorem rigorously deduced from given postulates may be regarded as a hypothesis about the actual world which xperience may show to be false.”

Richard Stone (1913–1991) British economist, Nobel Memorial Prize winner

“In spite of the moderate usefulness of what the economist has to say on this subject… there is a cry for a cultural anthropologist or even a psychologist when the economist runs into sacred cows, extended families, traditional motivations, levels of achievement, and social morale, all of which may be more important to economic development than any of the traditional economic variables. We still await a true synthesis of the insights of economics with those of other social sciences in the area”

“The historic terrain of macro-economic theory is the explanation of the levels and fluctuations of overall economic activity. Macro-economists have been especially interested in the effects of alternative fiscal, financial, and monetary policies.”

“Economists often talk about the benefits of choice, but rational economic man doesn't actually have much freedom to chose, because he is a slave to his own preferences.”

“I do not overlook the important contributions to economic theory in the past whether orthodox or heterodox I correlate them with institutional economics. The classical and communistic economists used as their measure of value the man hour of labor. This is evidently since the incoming of scientific management the engineering economics of efficiency. The Austrian and hedonistic economists deriving from Bentham used as the measure of value the diminishing marginal utility of consumption goods. This is evidently the home economics recently introduced in the college curriculum.”

“The purpose of studying economics is not to acquire a set of ready-made answers to economic questions, but to learn how to avoid being deceived by economists.”

“In spite of assigning little influence of economists' preachings on actual public policy, I do not believe that economists' influence is negligible. The reconciliation of these views lies in the fact that economists are scientists as well as preachers. Our science seeks to understand how economic institutions and economic systems work, and no informed person can deny that we have made much progress in this work.”

George Stigler (1911–1991) American economist

“Economics is a subject that really relates to core aspects of human well-being, and there’s a methodology for thinking about these things. This was a very appealing combination to me. Market systems are capable of massive breakdowns that can result in long, devastating periods of high unemployment. And I felt that economists had really learned something about how to address that.”

Janet Yellen (1946) American economist and professor

“We have defined the main task of economic analysis as the explanation of the magnitudes of economic quantities. The student will find also that the main part of this, as of most other works on the subject, is concerned with the theory of the determination of prices, wages, interest rates, incomes, and the like. He may well inquire, therefore, in the midst of so much mathematics, whether the first task of economics is not the investigation of wealth, or welfare. Some economists have endeavored to restrict the boundaries of the science to the investigation of those quantities which are numerically measurable. Well-being, under such a restriction, would not be part of economics at all.”

Kenneth E. Boulding (1910–1993) British-American economist

“Many of the stories economists tell take the form of models—for whatever else they are, economic models are stories about how the world works.”
