Economics
Economics () is the social science that studies the production, distribution, and consumption of goods and services.
Game
A game is a structured form of play, usually undertaken for enjoyment and sometimes used as an educational tool. Games are distinct from work, which is usually carried out for remuneration, and from art, which is more often an expression of aesthetic or ideological elements. However, the distinction is not clear-cut, and many games are also considered to be work (such as professional players of spectator sports or games) or art (such as jigsaw puzzles or games involving an artistic layout such as Mahjong, solitaire, or some video games).
Theory
A theory is a contemplative and rational type of abstract or generalizing thinking, or the results of such thinking. Depending on the context, the results might, for example, include generalized explanations of how nature works. The word has its roots in ancient Greek, but in modern use it has taken on several related meanings.
Theory
During the period that began with classical Greece and ended with late pagan antiquity, philosophy was more than merely a theoretical discipline. Even when Aristotle identified philosophy with "theory," his purpose is to argue ... that a life of theoretical activity, the life of philosophy, was the best life that human beings could lead.
Alexander Nehamas, The Art of Living (1998)
Game
All my games were political games; I was, like Joan of Arc, perpetually being burned at the stake.
Indira Gandhi, as quoted in The New York Times Biographical Service (1971), Vol. 2, p. 4027.
Economics
In my youth it was said that what was too silly to be said may be sung. In modern economics it may be put into mathematics.
Ronald Coase, The firm, the market and the law (1988) Chapter 6. A remark on "The problem of social cost" (last sentence).
