The Ultimatum Game: Using Game Theory to Study Self-Interest. In the simplest form of the ultimatum game, a proposer decides how much of $10 to give a responder, and the responder decides whether to accept or reject the offer. If the responder accepts, the players split the money in the way the proposer suggested..
How the ultimatum game can help explain behavioral economics?
A key focus of recent ultimatum game research has been to understand why responders reject low offers. Economic theory based on self-interested preferences suggests responders should accept any positive offer and consequently, proposers should offer the smallest possible positive amount..
What does the ultimatum game demonstrate about the behavior of economic agents?
What does the ultimatum game demonstrate about the behavior of economic agents? The economic agent on the receiving side of an interaction responds well to threats. Economic agents on both sides of an interaction do not respond well to threats..
What does the ultimatum game experiment suggest about human behavior?
Experimentally, fairness can be studied using the Ultimatum Game, where the decision to reject a low, but non-zero offer is seen as a way to punish the other player for an unacceptable offer. The canonical explanation of such behavior is inequity aversion: people prefer equal outcomes over personal gains..
What does the ultimatum game teach us?
The ultimatum game is important from a sociological perspective, because it illustrates the human unwillingness to accept injustice. The tendency to refuse small offers may also be seen as relevant to the concept of honour..
What is the 3 player ultimatum game?
The implemented game is a three-person (simultaneous move) ultimatum game with one proposer and two responders. The proposer proposes a split of a pie (money) be- tween himself and the two responders. Both responders simultaneously decide whether to accept or reject the proposal..
What is the history of the ultimatum game?
Although the Ultimatum Game had first been described in 1961 by Nobel laureate John Harsanyi, its first experimental analysis was devised during the 1980s by some German scholars supervised by Professor Werner G\xfcth. The Ultimatum Game is basically a bargaining game..
What is the ultimatum game in behavioral economics?
A widely used behavioral task in the research of negative reciprocity is the ultimatum game (UG). In a typical UG, participants act as a responder and decide whether to accept a fair or unfair division of money suggested by a proposer (Sanfey et al., 2003)..
What is the ultimatum game in economics?
The ultimatum game is a simple strategic situation between two people. One person, called the proposer, divides a fixed amount of money into two parts. This division is presented to the second person, termed the responder, as a 'take it or leave it' offer (hence the name 'ultimatum')..
What is the ultimatum game in game theory?
Definition. The ultimatum game is a task that allows us to test the predictions of game theoretical assumptions. In a standard ultimatum game, two players share roles as the proposer and the responder. The task is to divide a constant sum of money in a one-shot interaction..
What is the ultimatum game in real life?
A canonical example is the Ultimatum Game: one player proposes a division of a sum of money between herself and a second player, who either accepts or rejects. Based on rational self-interest, responders should accept any nonzero offer and proposers should offer the smallest possible amount..

Who invented the ultimatum game?
The ultimatum game was first introduced to the literature by G\xfcth, Schmittberger, and Schwarze [1982]. It is a one-shot two-stage sequential bargaining game. It is often used to illustrate the backward induction method of solving for a subgame perfect Nash equilibrium for monetary payoff maximizing players..

The results of the ultimatum game illustrate the fact that people's behavior is often driven by an innate sense of fairness. homo economicus is a good description of people's behavior. self-interest brings out the most efficient economic outcome.
The ultimatum game is an experimental economics game in which two parties interact anonymously and only once, so reciprocation is not an issue.
The ultimatum game is important from a sociological perspective, because it illustrates the human unwillingness to accept injustice. The tendency to refuse small offers may also be seen as relevant to the concept of honour.
Negative Reciprocity. A widely used behavioral task in the research of negative reciprocity is the ultimatum game (UG). In a typical UG, participants act as a responder and decide whether to accept a fair or unfair division of money suggested by a proposer (Sanfey et al., 2003).
In the traditional ultimatum game experiment, two players are randomly and anonymously matched. One person, the proposer, receives a fixed amount of money and must offer a suggested split of this money with another person, the responder. The responder must accept or reject the offer as it is presented.

The ultimatum game is a simple strategic situation between two people. One person, called the proposer, divides a fixed amount of money into two parts. This division is presented to the second person, termed the responder, as a 'take it or leave it' offer (hence the name 'ultimatum').
Ultimatum Games
The proposer is endowed with an amount of money, and suggests a division of that amount between herself and her responder. The responder observes the suggestion and then decides whether to accept or reject. If the division is accepted then both earn the amount implied by the proposer's suggestion.
Are unfair offers playing an ultimatum game with women and men?

Experimental tool
The dictator game is a popular experimental instrument in social psychology and economics, a derivative of the ultimatum game. The term game is a misnomer because it captures a decision by a single player: to send money to another or not. Thus, the dictator has the most power and holds the preferred position in this “game.” Although the “dictator” has the most power and presents a take it or leave it offer, the game has mixed results based on different behavioral attributes. The results – where most dictators choose to send money – evidence the role of fairness and norms in economic behavior, and undermine the assumption of narrow self-interest when given the opportunity to maximise one's own profits.

The public goods game is a standard of experimental economics. In the basic game, subjects secretly choose how many of their private tokens to put into a public pot. The tokens in this pot are multiplied by a factor and this public good payoff is evenly divided among players. Each subject also keeps the tokens they do not contribute.

Game in economic experiments
The ultimatum game is a game that has become a popular instrument of economic experiments. An early description is by Nobel laureate John Harsanyi in 1961. One player, the proposer, is endowed with a sum of money. The proposer is tasked with splitting it with another player, the responder. Once the proposer communicates his decision, the responder may accept it or reject it. If the responder accepts, the money is split per the proposal; if the responder rejects, both players receive nothing. Both players know in advance the consequences of the responder accepting or rejecting the offer.
