Effects of saving and spending patterns on holding time distribution

چکیده
The effects of saving and spending patterns on holding time distribution of money are investigated based on the ideal gas-like models. We show the steady-state distribution obeys an exponential law when the saving factor is set uniformly, and a power law when the saving factor is set diversely. The power distribution can also be obtained by proposing a new model where the preferential spending behavior is considered. The association of the distribution with the probability of money to be exchanged has also been discussed.

Introduction According to general census in 2011, rural population of the country has been over 21 million and 603 thousand people. Considering the per capita monthly subsidy equivalent to 455,000 riyals, it can be resulted that in the first three years of the project, over 353 trillion has been allocated to rural community. Calculations show that this amount is equivalent to 2.4% of the tot...
متن کاملDistributed Generation Effects on Unbalanced Distribution Network Losses Considering Cost and Security Indices
Due to the increasing interest on renewable sources in recent years, the studies on integration of distributed generation to the power grid have rapidly increased. In order to minimize line losses of power systems, it is crucially important to define the size and location of local generation to be placed. Minimizing the losses in the system would bring two types of saving, in real life, one is ...

متن کاملDynamic Process of Money Transfer Models
We have studied numerically the statistical mechanics of the dynamic phenomena, including money circulation and economic mobility, in some transfer models. The models on which our investigations were performed are the basic model proposed by A. Drăgulescu and V. Yakovenko [1], the model with uniform saving rate developed by A. Chakraborti and B.K. Chakrabarti [2], and its extended model with di...
