Agent-based modeling/simulation is an emergent approach to the analysis of social and economic systems. It provides a bottom-up experimental method to be applied to social sciences such as economics, management, sociology and politics as well as some engineering fields dealing with social activities. This book includes selected papers presented at the Eighth International Workshop on Agent-Based Approaches in Economic and Social Complex Systems held in Tokyo, Japan, in 2013. At the workshop, 23 reviewed full papers were presented and of those, 13 were selected to be included in this volume.

Japanese Role-playing Games: Genre, Representation, and Liminality in the JRPG examines the origins, boundaries, and transnational effects of the genre, addressing significant formal elements as well as narrative themes, character construction, and player involvement. Contributors from Japan, Europe, North America, and Australia employ a variety of theoretical approaches to analyze popular game series and individual titles, introducing an English-speaking audience to Japanese video game scholarship while also extending postcolonial and philosophical readings to the Japanese game text. In a three-pronged approach, the collection uses these analyses to look at genre, representation, and liminality, engaging with a multitude of concepts including stereotypes, intersectionality, and the political and social effects of JRPGs on players and industry conventions. Broadly, this collection considers JRPGs as networked systems, including evolved iterations of MMORPGs and card collecting "social games" for mobile devices. Scholars of media studies, game studies, Asian studies, and Japanese culture will find this book particularly useful.

Economics went through great development in the 20th century. This development, which was based mainly on mathematical methods, is not an appropriate method of analyzing markets that change every hour and every day. In a stock market, prices constantly change depending on speculation. U-Mart, a manmade market, has been proposed in order to study such instantly moving markets. Although the U-Mart system is internationally acclaimed for being at the forefront of market research, its use is by no means limited to a small number of researchers on the fringe. The whole system, including its source code, is open and is distributed without charge, testifying to a philosophy of creating and providing a common test bed for research into financial markets.
