Information economics or the economics of information is the branch of microeconomics that studies how information and information systems affect an economy and economic decisions. [ 1 ] One application considers information embodied in certain types of commodities that are "expensive to produce but cheap to reproduce."
Quantitative uses of the terms uncertainty and risk are fairly consistent among fields such as probability theory, actuarial science, and information theory. Some also create new terms without substantially changing the definitions of uncertainty or risk. For example, surprisal is a variation on uncertainty sometimes used in information theory ...
In game theory, a Bayesian game is a strategic decision-making model which assumes players have incomplete information. Players may hold private information relevant to the game, meaning that the payoffs are not common knowledge. [1] Bayesian games model the outcome of player interactions using aspects of Bayesian probability.
In contract theory, mechanism design, and economics, an information asymmetry is a situation where one party has more or better information than the other. Information asymmetry creates an imbalance of power in transactions, which can sometimes cause the transactions to be inefficient, causing market failure in the worst case.
Consider a network game of local provision of public good [4] when agent's actions are strategic substitutes, (i.e. the benefit of the individual from undertaking a certain action is not greater if his partners undertake the same action) thus, in the case of strategic substitutes, equilibrium actions are non-increasing in player's degrees.
In economics and game theory, complete information is an economic situation or game in which knowledge about other market participants or players is available to all participants. The utility functions (including risk aversion), payoffs, strategies and "types" of players are thus common knowledge .
In economics and game theory, global games are games of incomplete information where players receive possibly-correlated signals of the underlying state of the world. Global games were originally defined by Carlsson and van Damme (1993).
The Blackwell order has many applications in decision theory and economics, in particular in contract theory. For example, if two information structures in a principal-agent model can be ranked in the Blackwell sense, then the more informative one is more efficient in the sense of inducing a smaller cost for second-best implementation.
