经济动力学中的间断均衡与幂律

Punctuated Equilibrium and Power Law in Economic Dynamics

Abhijit Kar Gupta

摘要:

Thurner { \it et al.}最近提出了一个有趣的熊彼特经济动力学玩具模型。经济学家约瑟夫·熊彼特的观点。间断的平衡动力学被证明是从这个模型中出现的,并且对时间序列的一些详细分析表明SOC类行为。在目前的工作重点是折腾的想法是否动力学真的可以像一个自组织临界(SOC)类型。这项研究表明,它是必要的,以获得幂律,从而SOC的行为,在这样一个模型中的生物进化模型线的“健身”和“选择”的概念。

英文摘要:

An interesting toy model has recently been proposed on Schumpeterian economic dynamics by Thurner {\it et al.} following the idea of economist Joseph Schumpeter. Punctuated equilibrium dynamics is shown to emerge from this model and some detail analyses of the time series indicate SOC kind of behaviours. The focus in the present work is to toss the idea whether the dynamics can really be like a self organized critical (SOC) type. This study indicates that it is necessary to incorporate the concepts of 'fitness' and 'selection' in such a model in the line of the biological evolutionary model by Bak and Sneppen in order to obtain power law and thus SOC behaviour.
