Dictator - Dictators in Game Theory

Dictators in Game Theory

In social choice theory, the notion of a dictator is formally defined as a person who can achieve any feasible social outcome he/she wishes. The formal definition yields an interesting distinction between two different types of dictators.

• The strong dictator has, for any social goal he/she has in mind (e.g. raise taxes, having someone killed, etc.), a definite way of achieving that goal. This can be seen as having explicit absolute power, like Sulla.
• The weak dictator has, for any social goal he/she has in mind, and for any political scenario, a course of action that would bring about the desired goal. For the weak dictator, it is usually not enough to "give their orders", rather he/she has to manipulate the political scene appropriately. This means that the weak dictator might actually be lurking in the shadows, working within a political setup that seems to be non-dictatorial. An example of such a figure is Lorenzo the Magnificent, who controlled Renaissance Florence.

Note that these definitions disregard some alleged dictators, e.g. Benito Mussolini, who are not interested in the actual achieving of social goals, as much as in propaganda and controlling public opinion. Monarchs and military dictators are also excluded from these definitions, because their rule relies on the consent of other political powers (the barons or the army).
