Abstract

Microeconomic theory assumes economic agents are rational when making decisions. In many ways numerical capabilities indicate a measure of the rationality of economic agents. Beauty contest games are one of the games commonly used in an experiment to show the failure of economic agents to make decisions based on numerical rationality. This article is written based on the results of economic experiments in the learning class (classroom experiments) using the BCG model with the aim of knowing the rationality of economic agents in making decisions. The results of the study show that economic agents do not fully act on numerical rationality so they cannot succeed in maximizing utility or achieving Nash equilibrium. Keywords : beauty contest game, guessing game, rationality, economic experiment, nash equilibrium

Abstract

Ultimatum game is one of the game theory models used in an experiment to show the behavior of economic agent decision making that deviates from the basic principles of microeconomic theory. An experimental unit with a game consists of two participants, each called the first player (proposer) and the second player (responder). This study discusses the use of ultimatum games in economic experiments in the classroom. The purpose of this study is to determine the average proposal offered by the first player (proposer) and the average proposal that is not rejected by the second player (responder). The experiment participants were 15 people and each of them participated in the same experiment three times. In each experiment each played the role of first player and second player. Placement of participants in the experimental unit is done randomly. The experimental results show that for the whole experiment the average offer value is 66.16 for the proposer and 33.84 for the responder; while the average value of offers that were not rejected by respondents was 64.50 for proposers and 35.50 for respondents. Most of the behaviors of respondents who refuse offers are consistent with the distributional preferences theory.Keywords: ultimatum game, classroom experiment, fairness, distributional preferences

Abstract

N-Persons Prisoner’s Dilemma Games (NPDG) is a form of Prisoner’s Dilemma Games (PDG) involving more than 2 players. Economic classroom experiments using NPDG relatively have not been done, especially in Indonesia. This experiment was conducted to determine the effect of changes in payoff structure on the cooperation rates in NPDG. ANOVA shows insufficient evidence to state that the changes in payoff affect the rates of cooperation payoff. Non-monetary rewards on experimental execution and the unexpected reasons of participants to make choices allegedly explain why the results of hypothesis testing are not significant.Keywords: experimental economics, n-person prisoner’s dilemma, changes in payoff structure, rate of cooperation
