Unexpected changes, on the contrary, lead to windfall gains or losses — George Stigler

"The great disservice of the leaders of Negro opinion was to direct the discontent at the white population. It was proper to demand political rights that only a majority could confer. It was proper to ask the white population to assist in the rise of the Negro—a small enough restitution for the unreversible mistakes of the past. But it was a terrible disservice to identify the white man as the main obstacle to the rise of the Negro."

"The state --the machinery and power of the state-- is a potential resource or threat to every industry in the society. With its power to prohibit or compel, to take or give money, the state can and does selectively help or hurt a vast number of industries. That political juggernaut, the petroleum industry, is an immense consumer of political benefits, and simultaneously the underwriters of marine insurance have their more modest repast. The central tasks of the theory of economic regulation are to explain who will receive the benefits or burdens of regulation, what form regulation will take, and the effects of regulation upon the allocation of resources."

"Two main alternative views of the regulation of industry are widely held. The first is that regulation is instituted primarily for the protection and benefit of the public at large or some large subclass of the public. In this view, the regulations which injure the public -as when the oil import quotas increase the cost of petroleum products to America by $5 billion or more a year- are costs of some social goal (here, national defense) or, occasionally, perversions of the regulatory philosophy. the second view is essentially that the political process defies rational explanation: "politics" is an imponderable, a constantly and unpredictably shifting mixture of forces of the most diverse nature, comprehending acts of great moral virtue (the emancipation of slaves) and of the most vulgar venality (the congressman feathering his own nest)."

"A rational man must be guided by the incentive system within which he operates. No matter what his own personal desires, he must be discouraged from certain activities if they carry penalties and attracted toward others if they carry large rewards. The carrot and the stick guide scientists and politicians as well as donkeys."

"The user of a theory has a simpler task: his not to reason why, his but to sigh and try. If the right element in the diverse situations has been isolated, the theory will work: it will yield predictions better than those which can be reached with any alternative theory."

"Some important aspects of important aspects of economic organization take on a new meaning when they are considered from the viewpoint of the search of information."
