中文简介:
我们建立了一个互动主体系统的模型,该系统以给定的财富和一定的犯罪倾向为特征,用诚实系数来衡量。这种诚实与内在因素有关,比如道德上的障碍,以及外在的因素,比如如果犯罪就有被监禁的风险。在模拟中,agent的诚实程度是可变的,一方面是惩罚水平的函数,另一方面是与其他agent的接触(学习或传染效应)。每个居住者的犯罪数量是被抓住的概率的函数。一个明显的相变被观察到作为惩罚概率的函数。这意味着,一旦犯罪行为达到了很高的水平,报复的可能性必须大大增加,以便回到低犯罪的状态。此外,还观察到一些前兆信号,表明可能发生犯罪活动。我们还分析了犯罪的其他后果,如经济增长,财富分配的不平等(基尼系数)和其他相关数量在不同的犯罪活动场景和逮捕概率下。
课程简介: We model a system of interacting agents characterized by a given wealth and a certain criminal propensity, measured by an honesty coefficient. This honesty is related to intrinsic factors, like moral barriers, and extrinsic ones, as the risk of being imprisoned if committing an offense. In the simulation the honesty level of the agents is variable, and a function of the level of punition, on one hand, and on the contact with other agents (learning or contagion effect) on the other hand. The number of crimes per habitant is measured as a function of the probability of being caught. A sharp phase transition is observed as a function of the probability of punishment. That means that once criminality has attained a high level, the probability of retribution must considerably increase in order to come back to a state of low criminality. Also, some precursor signals are observed that indicate possible bursts of crime activity. We also analyze other consequences of criminality as the growth of the economy, the inequality in the wealth distribution (the Gini coefficient) and other relevant quantities under different scenarios of criminal activity and probabilities of apprehension.
