Any activity requires the use of energy. Economic activity
is not possible without energy,
especially fossil fuels. An increase in economic activity necessarily
leads to an increase in the use fossil
fuels and greenhouse gas emissions. In addition there will be a commensurate increase in waste products,
pollution and heat. This is dictated by the laws of physics and unavoidable. A problem arise when the cost of this degeneration
caused by continual economic growth surpasses the benefit society derives from it. The ecological economist Professor Herman Daly (2014) explained that
when the impact on the ecosystem is correctly measured, global growth has reached
a point where the total private and social costs of economic growth outweigh
the private and social benefits. In other words, more economic growth is making global society worse off overall - growth has become uneconomic! The model
shows that eventually pressures will build up that counteract the perennial
belief that all social ills can be solved with economic growth.

I made this model to simulate how a companies revenue will change depending on the lifetime of the appliances it manufactures, in combination with the ratio of repair costs and price. It also shows the accumulation of e-waste.

• This model examines how sustainable consumerism is from social, economic, and environmental aspects. The question in focus is "
How will our second-hand clothing donations affect communities in developing countries, specifically Kenya?"
5 Stock Variables:
• U.S. Consumers
• Multinational Corporations
• Overseas Factories
• Kenya
Highlight Findings:
To sum up, there are 4 major problems associated to donations:
• 1.
Source of problem is the consumer: Cheap deals attract hundreds of millions in revenue for fast fashion, and contribute to 100,000 tonnes of clothing to Kenya annually.
• 2. Rapid consumerism leads to over-utilization of slowly-renewable resources, such as water.
• 3. Nearly 96% of textiles jobs are eradicated by the massive inflow of clothing donations to Kenya.
• 4. The offshoring of textiles jobs enrages U.S. blue-collar workers, leading to the rise of protectionism.

When people talk about a government deficit, they forget
that this is only one side of the ledger. On the other is a corresponding non-government
SURPLUS. The money the government spends is not lost but shows up in the private
sector as income. When one talks only of the deficit then one can understand that
many think it should be reduced or even converted into a surplus, but reducing
the government deficit reduces private sector income and a government surplus
forces a deficit on the private sector with a potentially devastating
effect on private sector wealth and economic activity. Unless the economy is overheating, government
deficits are usually healthy. For countries that run traditionally a trade deficit,
such as the US they are necessary to maintain economic activity. Consider this
fact: for almost all of past 40 years the US and the UK have run deficits without
any harmful effects!

The model is built to demonstrates how Burnie Tasmania can deal with a new COVID-19 outbreaks, taking government policies and economic effects into account.
The susceptible people are the local Burnie residents. If residents were infected, they would either recovered or dead. However, even they do recover, there is a chance that they will get infected again if immunity loss occurs.
From the simulation result we can see that with the implementation of local government policies including travel ban and social distancing, the number of infected people will decrease. The number of recovered people will increase in the first 5 weeks but then experience a decrease.
In addition, with the implementation of local government policy, the economic environment in Burnie will be relatively stable when the number of COVID-19 cases is stable.
How Burnie, Tasmania can deal with a new outbreak of COVID-19
Introduction
This model simulates the COVID-19 outbreaks in Burnie, the government reactions, as well as the economic impact. The government's strategy is based on the number of COVID-19 cases reported and testing rates and recovered.
Assumptions
In the same trend that government policy decreases infection, it also reduces economic growth.
When there are ten or fewer COVID-19 cases reported, government policy is triggered.
The economy suffers as a result of an increase in COVID-19 cases.
Interesting insights
The higher testing rates appear to result in a more quick government response, resulting in fewer infectious cases. However, it has a negative influence on the economy.

This is a toy model of an investment market.
Households follow a simple ratio to invest in bonds or equities. In part, the investment decision is stochastic, such that stock market returns are volatile, with equities more volatile than bonds and with a higher yield. As such, the system shows increasing volatility as the investment bubble grows.

economic capital has a reinforcing loop (investment of output) governing growth and a balancing loop (depreciation) governing decline.
