| Project Title: |
| Numerical Study of Econophysical Systems |
| Project Description: |
| To demonstrate the applicability of physical approaches to realistic economic systems, we study the dynamics and cooperative simple minded model so called Minority Game (MG) using statistical mechanics in physics. |
| Project Duration: |
| 24 months |
| Project Significance: |
|
Econophysics is the study of economical systems via physical methods, which
is an example of linking physics to other fields. In particular, Game Theory
provides explanation of phenomena in economical systems people encounter in
daily life. This project, being a extension of the well-known Minority Game in Game Theory, is aimed to widen the research space of econophysics. It is hoped that the results of this project might provide inspiration on further study in Game Theory. It is also anticipated that some collaboration could be made with other researchers, including those from HKU and other universities. Also, this project also states the variety of research in our department, as well as HKU. |
| Results Achieved: |
| In summary, we investigate the inequality of wealth among the players of MG using the well-known wealth inequality measure in economics called the modified Gini index. Numerical results generated by HPCC were analyzed and a paper presenting these results will be submitted. Moreover, the Gini index can be reproduced using replica tricks in statistical mechanics. |
| Remarks on the Use of High Performance Computing: |
| This project involves large amount of computational calculations and simulations, which require demanding computational power. By using HPC Cluster, we can greatly shorten the running time of our computer programs. Say, after using the computer cluster, the execution time substantially reduced 100 times. |
