Decision theory or the theory of choice not to be confused with choice theory is the study of an agent's choices. Decision theory is closely related to the field of game theory [2] and is an interdisciplinary topic, studied by economists, statisticians, psychologists, biologists, [3] political and other social scientists, philosophers, [4] and computer scientists. Empirical applications of this rich theory are usually done with the help of statistical and econometric methods. Normative decision theory is concerned with identification of optimal decisions where optimality is often determined by considering an ideal decision maker who is able to calculate with perfect accuracy and is in some sense fully rational. The practical application of this prescriptive approach how people ought to make decisions is called decision analysis and is aimed at finding tools, methodologies, and software decision support systems to help people make better decisions. In contrast, positive or descriptive decision theory is concerned with describing observed behaviors often under the assumption that the decision-making agents are behaving under some consistent rules. These rules may, for instance, have a procedural framework e.
In game theory , strategic dominance commonly called simply dominance occurs when one strategy is better than another strategy for one player, no matter how that player's opponents may play. Many simple games can be solved using dominance. The opposite, intransitivity , occurs in games where one strategy may be better or worse than another strategy for one player, depending on how the player's opponents may play. When a player tries to choose the "best" strategy among a multitude of options, that player may compare two strategies A and B to see which one is better.
This on-line document is presented as a summary of some of the main ideas in that book. Who has predominant power in the United States?

George Washington was one of the biggest landowners of his day; presidents in the late 19th century were close to the railroad interests; for the Bush family, it was oil and other natural resources, agribusiness, and finance.
