According to Wikipedia Chess is an abstract strategy board game for two players which involves no hidden information and no elements of chance.
Also It is played on a square game board called a chessboard containing 64 squares arranged in an 8 by 8 grid.
The players, referred to as "White" and "Black", each control sixteen pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns; each type of piece has a different pattern of movement.
imagine economics as a giant chess game where every move you make depends on what you think others will do that's game theory developed by John Von Newman and later revolutionized by John Nash.
Other economic Theory market price and economic system games Theory is more of choice since economics is also the study of choices when resources are inadequate
Game theory is used to measure competition, co-operation and negotiations among economic agents (Household, Firm and Government) it helps economists understand behaviors and how choices and decisions are made
But can the economy be measured or simplified to a chess board this oversimplification can tender the theory inadequate chess involve only two players while the economy deals with many countless players and each player in a chess game is informed and have perfect knowledge of each piece but in economics it's assumed that perfect knowledge exists but things changes overtime.
but the theory is still useful because it helps in decision making and predicting economic outcomes.
Unlike the static board of Chess that remains unchanged overtime consumers preferences and technological advancements change overtime and the playing field is always not leveled.
