초록/요약
The origin of fundamental uncertainty lies in the interdependent ex- pectations. In this paper, simple investment game with proportional pay- off regime is considered to analyse the effect of additional information. In this game, agents make portfolio of risky asset and risk free asset. Risk free asset gives fixed rate of return regardless of macroeconomic state but the rate of return of risky asset is dependent on macroeconomic state: crisis state and normal state. This macroeconomic state is deter- mined by the weighted average of individual portfolio and wealth. The crisis threshold is common knowledge. In this game, the Nash equilibrium portfolio is exactly the crisis threshold level. But because of the loss from crisis state and uncertainty about other agents’ strategies, Nash equilib- rium portfolio lies safer area than theoretical Nash equilibrium. The web based, extra credit rewarded experiments for this investment game was conducted with undergraduate students in Korea University. They used their information to maximize their own wealth, but the positive effect to the rates of return of informed groups were not prominent. In the agent-based simulation for this investment game was done and one more condition was considered: additional payoff regime to compare the re- sult of traditional game theory. The result was that information showed positive effect in the additional payoff regime. However in the propor- tional payoff regime, additional information showed no clear contribution to the rate of return and clear negative effect to the fluctuation of the macroeconomic state. This suggests that there may exist some condition in which true additional information have negative effect.

Open source software(OSS) has no explicit pecuniary incentive. OSS project has the free riding problem but there is no way to punishment. However many OSS projects are deveoloped and survived. How can OSS compete against Proprietary Software(PS) and be survived? Many re- searchers have tried to explain this puzzle. This paper have focus on the group selection originated from the competition between OSS and PS. For this, a simple agent-based model is suggested. In this model, all agents can choose among OSS using for free, OSS developing, and PS using with endogeneously determined price. The object of agents is to maximize their own measurable happiness from using S/W or enjoying leisure time. Also the heterogeniety of the developing power is considered. In this model, initial market share of OSS and the probability to take part in the developing OSS is important factor for the survive of OSS, and heterogeneity of developing power showed no clear role in the survival of OSS.

천안–논산과 대구–부산 구간은 출발지와 목적지가 같지만, 도로공사 와 민간투자회사로 고속도로의 운영주체와 경로가 이원화 되어 있으며, 이용 요금도 서로 다르다. 두 경로의 특성이 다를 경우, 개별 차량의 비용 극소화 선택은 사회적 최적 선택과 유리될 수 있다. 하지만, 각 경로에 도로 사용 요금을 차등 부과할 수 있다면, 두 요금의 차이가 유인이 되어 사회적 최적 통행 배분을 유도할 수 있다. 본 논문은 도로 요금 산정에 일반적으로 쓰이는 단기 비용 함수(VDF)에 기반하여 네트워크 효율성 지표인 “자유선택의 비용(PoA: Price of Anarchy)”을 사용하였다. PoA 는 총정체비용을 기준으로 계산되었으며, 이를 토대로, 도로공사 요금 대 비 최적 민간투자 고속도로 이용요금을 산출하였다. PoA의 시뮬레이션에 따르면, 천안–논산 구간은 현행 가격보다 높이고, 대구–부산 구간은 현행 가격보다 낮출 경우, 통행 배분을 개선할 수 있다. 핵심어: 자유선택의 비용(Price of Anarchy), 민간투자 고속도로, 고속도로 이용요금, 총정체비용 JEL Classification Numbers: R41, R48
