"Microeconomics, including the study of individual choice and of group choice in market and nonmarket processes, has generally been considered a field science as distinct from an experimental science. Hence microeconomics has sometimes been classified as "non-experimental" and closer methodologically to meteorology and astronomy than to physics and experimental psychology . But the question of using experimental or nonexperimental techniques is largely a matter of cost, and generally the cost of conducting the most ambitious and informative experiments in astronomy, meteorology, and economics varies from prohibitive down to considerable. The cost of experimenting with different solar system planetary arrangements, different atmospheric conditions, and different national unemployment rates, each under suitable controls, must be regarded as prohibitive."

“One of the most intriguing discoveries of experimental economics is that as we have seen, people invariably behave non-cooperatively in small and large group ‘impersonal’ market exchange institutions; many cooperate in ‘personal’ exchange ; yet in both economic environments all interactions are between anonymous players.”

“Economics as currently learned and taught in graduate school and practiced afterward is more theory-intensive and less observation-intensive than perhaps any other science. I think the statement that "no mere fact ever was a match in economics for a consistent theory" accurately describes the prevailing attitude in the profession .”

“Even though Hayek, in my view, is the leading economic thinker of the 20th century who saw what must be the mainsprings of the extended order, Mises was the choice technician, and no one was better at articulating the primacy of the individual and the need to define and nurture individual rights.”

“The vast majority of individuals with Asperger Syndrome need help — without that help they won't be able to do very well. The individuals that I know have to overcome a great deal of difficulty to maximize their potential and get the things in life they deserve.”

“Complexity. In general individual decision makers must be assumed to have multidimensional values which attach nonmonetary subjective cost or value to the process of making and executing individual or group decisions, the end result of such decisions, and the rewards of other individuals involved in the decision process.”

“I think it's different kinds of minds, and the recognition that certain mental deficiencies may actually have some selective advantages in terms of activities. We've lost a lot of the barriers that have to do with skin color and with various other characteristics. But there's still not sufficient recognition of mental diversities. And we don't all have to think alike to be communal and to live in a productive and satisfying world.”
