This paper analyzes the role of peer pressure in a partnership, when there is moral hazard. Free-rider is a well-known problem in the multiagent setting of team production when team members agree to share the output.
A partnership is an association that divides its output equally. Using mathematical models, it was confirmed that there becomes a free-rider problem in partnership. Peer pressure can be an effective solution of free-rider problem. Lazear and Kandel's research in 1992 focuses on the conditions under which peer pressure operates in an industrial environment
In this study, Agent-Based Modeling, using JAVA and Repast, was used for the experiment of free-rider problem and role of peer pressure with more realistic environment. Heterogeneous agents and their expectation schemes on other agents were introduced. For peer pressure, the concept of norm was used. Each agent can feel shame and pride while they interact Only agents can monitor other agents, peer pressure can be effective. Through those settings, I researched the effect of each variable used for ABM, on equilibrium effort and level of profit.
본 연구는 파트너쉽 형태의 조직에서 나타나는 도덕적 해이 문제로서, free-rider 현상에 대해 살펴보았다. 조직의 크기가 확대됨에 따라 free-rider현상이 어떻게 나타나는가에 대한 분석과 더불어, peer pressure의 효과가 free-rider현상을 얼마나 극복해 낼 수 있는 가를 살펴보았다. 이러한 모든 과정들을 수리적으로 분석해 보았고 이후 Agent-Based 모델링을 통하여 다양한 에이전트들의 속성을 반영했을 때, 결과에 어떠한 영향을 주는가에 대하여 분석해 보았다.
