1. Abstract |
From the advice we received from entrepreneurs, we introduced economic wave into our system. Even though the introduction of economic wave destructs the system of Company and Customer, Bank helps Company and Customer to grow well. |
| |
|
| |
2. Integration to our circuit |
Our integrated economic wave is expressed as in Fig. 4-4-2-1. |

This term is added to the C4HSL equations as in Fig. 4-4-2-2. |

3. Result |
3.1. Bank helps Company and Customer even in
the presence of economic wave |
Even though the Company and Customer can grow well only by themselves, introduction of economic wave destructs the system of Company and Customer. This is shown in Fig. 4-4-3-1. |

As shown in Fig. 4-4-3-2, the system of Company and Customer has enormous amount of money when there are no economic wave. But once the economic wave has been introduced, then because of the recession during the wave, they all die. |
When the Bank is added, Bank helps Company and Customer to grow well. This is shown in Fig. 4-4-3-3(left). The C4HSL concentration during the simulation is shown in Fig.4-4-3-3(right). |

| |
During the recession in the economic wave, the Bank supplies money to the economy. Because of this, they all can grow well. |
| |
3.2. Bank cannot help Company and Customer enough in the presence of harsh economic wave |
Additionally, we simulated how the system will behave in the presence of harsh economic wave. Harsh economic wave we introduced is described as in Fig. 4-4-3-4. |
| |
|

| |
With the presence of the harsh economic wave, the Company and Customer cannot survive. When the Bank is included, even though the Bank helps Company and Customer they cannot grow stably. This result is shown in Fig. 4-4-3-5. |

| |
Although the Bank tries to stable the money supply by switching its state many times(Fig. 4-4-3-6), since the fluctuation of money supply is very harsh (Fig. 4-4-3-6), Company and Customer cannot endure the fluctuation enough. |
