Varieties of agents in agent-based computational economics: A historical and an interdisciplinary perspective

In this paper, we trace four origins of agent-based computational economics (ACE), namely, the markets origin, the cellular-automata origin, the tournaments origin, and the experiments origin. Along with this trace, we examine how these origins have motivated different concepts and designs of agents in ACE, which starts from the early work on simple programmed agents, randomly behaving agents, zero-intelligence agents, human-written programmed agents, autonomous agents, and empirically calibrated agents, and extends to the newly developing cognitive agents, psychological agents, and culturally sensitive agents. The review also shows that the intellectual ideas underlying these varieties of agents cross several disciplines, which may be considered as a part of a general attempt to study humans (and their behavior) with an integrated interdisciplinary foundation.     

A SCIENTIFIC CLASSIFICATION OF VOLATILITY MODELS

Abstract.  Modeling volatility, or predictable changes over time and space in a variable, is crucial in the natural and social sciences. Life can be volatile, and anything that matters, and which changes over time and space, involves volatility. Without volatility, many temporal and spatial variables would simply be constants. Our purpose is to propose a scientific classification of the alternative volatility models and approaches that are available in the literature, following the Linnaean taxonomy. This scientific classification is used because the literature has evolved as a living organism, with the birth of numerous new species of models.

关于大中型工业企业库存物资分类的探讨

由于受传统计划经济的影响,在很长一段时期里,我国大中型工业企业的物资分类模式被深深地烙上了"计划"的印记。不能社会主义市场经济发展需要,创建科学的物资分类并使其顺应现代企业的管理,已经显得愈发重要了。     

对行事行为分类的诠释与批判

通过对以往语言学家对行事行为的分类的观察,阐述了不同种类的行事行为。其实在英语中,间接言语行为一般比直接言语行为更多与礼貌联系在一起。应该观察更大的范围,而不是一个单一的话语实施一个单一的言语行为。言语活动就是很好的材料。对言语活动的分析是研究更多言外之意的另一种途经。     

Endogenous fertility, international migration and growth

An endogenous growth model with heterogeneous agents and endogenous rates of fertility is developed to study the relationships between population growth, human capital, migration and economic development. A variety of patterns of migration, from the migration of the unskilled to the brain drain is considered, where the decision to migrate reflects the agents’ optimising behaviour. The analysis yields implications which accord with the empirical evidence on the relationships between demography and development. Macroeconomic policy can foster growth by influencing labour mobility through taxation and the provision of public goods such as social infrastructure, sanitation, environmental control and medical research that affect locational preferences and child quality. The author is grateful for the comments of an anonymous referee on an earlier version of the paper. The usual disclaimer applies.
