Application of the Option Game Theory to the Real Estate Enterprise Investment Decision

One of the remarkable characteristics of the current development of China's national economy is the increase of uncertainties, which makes the traditional method more and more unsuitable for the current economic development in the real estate investment process. Based on the option game theory, the investment decision making of real estate is analyzed here, the investment optimization mathematic model established, and Nash Equilibrium discussed. Through case studies, we analyze the application of game option in the real estate, which is put under symmetrical duopoly. The conclusions will contribute to both the theory on and practice of the present investment in the real estate enterprise.     

A differential game model for a developing and a developed country

A differential game (DG) model for a developing and a developed country is considered. Each player makes decisions about how much resource to be used to restrict the opponent's development so as to maximize his weighted sum of current consumption and final output. Current consumption is assumed to be preferred to final output for both players. The developing country is assumed to have a higher economic growth rate and a higher preference to final output, whereas the developed country is assumed to have a higher initial income and a higher efficiency in restricting his opponent. This problem is investigated under three kinds of information structures, i.e., a zerosum, a nonzero-sum, and a Stackelberg game. Open-loop equilibrium solutions are obtained for all the three cases. Economic implications of the result are provided. The research is supported by the National Natural Science Foundation of China under Grant Nos. 70771118 and 70371030 and the Scientific Research Foundation for the Returned Overseas Chinese Scholars, State Education Ministry under Grant No. 2006.331.     

福建省青少年游泳运动员比赛表现的影响因素探析

采用文献资料法、问卷调查法、数理统计法,对影响福建省青少年游泳运动员比赛表现的影响因素进行研究。经过对34个因素进行因子分析,得出影响运动员比赛表现的影响因素的9个主因子。对9大因子进行分析得知,运动员比赛表现是个人技战术水平、心理能力、客观环境、人为因素、赛前准备、教练信任、对手作用、最佳体验与自我评价等多方面因素影响的结果,为我国游泳运动员训练和赛前控制比赛状态提供理论参考。

Models as products of interdisciplinary exchange: Evidence from evolutionary game theory

The development of evolutionary game theory (EGT) is closely linked with two interdisciplinary exchanges: the import of game theory into biology, and the import of biologists’ version of game theory into economics. This paper traces the history of these two import episodes. In each case the investigation covers what exactly was imported, what the motives for the import were, how the imported elements were put to use, and how they related to existing practices in the respective disciplines. Two conclusions emerged from this study. First, concepts derived from the unity of science discussion or the unification accounts of explanation are too strong and too narrow to be useful for analysing these interdisciplinary exchanges. Secondly, biology and economics—at least in relation to EGT—show significant differences in modelling practices: biologists seek to link EGT models to concrete empirical situations, whereas economists pursue conceptual exploration and possible explanation.
