He was the recipient of the Nobel Memorial Prize in Economic Sciences in 1994. Harsanyi is best known for his contributions to the study of game theory and its application to economics, specifically for his developing the highly innovative analysis of games of incomplete information, so-called Bayesian games.
Repeated games can include some incomplete information. Repeated games with incomplete information were pioneered by Aumann and Maschler . [ 4 ] While it is easier to treat a situation where one player is informed and the other not, and when information received by each player is independent, it is possible to deal with zero-sum games with ...
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, the theory of rational inattention deals with the effects of the cost of information acquisition on decision making. For example, when the information required for a decision is costly to acquire, the decision makers may rationally take decisions based on incomplete information, rather than incurring the cost to get the complete information.
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 .
Bounded rationality attempts to address assumption points discussed within neoclassical economics theory during the 1950s. This theory assumes that the complex problem, the way in which the problem is presented, all alternative choices, and a utility function, are all provided to decision-makers in advance, [24] where this may not be realistic ...
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.
In economics, comparative statics is the comparison of two different economic outcomes, before and after a change in some underlying exogenous parameter. [1] As a type of static analysis it compares two different equilibrium states, after the process of adjustment (if any). It does not study the motion towards equilibrium, nor the process of ...
