Starts from the bathtub model of economics developed by TSSEF.se (see the explanation here). It adds rich and poor and you can change the constraints on the system by moving the sliders (taxes, wages, rates, dividends etc) to see how the economic system functions at national level.
I have tried every combination I can but I think you will agree with me that the system is unstable. OR maybe I forgot something.
Theory of Structural Change for IAMO Research Group
The part-whole paradigm
Examples of
research issues addressed here include the path dependence of farm structures,
regime shifts in land-system change, as well as transitional processes in the
evolution of farm structures and innovation systems. All these issues feature
counter-intuitive systemic properties that could not have been predicted using
standard agricultural economics tools. The key strength of the research group
in regard to the part-whole paradigm is the internationally renowned expertise
in the agent-based modelling of agricultural policy. (More on what happened here until now / is happening now)
The system-environment paradigm
This paradigm is represented by conceptual
research drawing inspiration from Niklas Luhmann’s theory of “complexity-reducing”
and “operationally closed” social systems. The attributes of complexity
reduction and operational closure are shown to generate sustainability
problems, conflicts, social dilemmas, ethical issues, and divergent mental
models. The organizing idea explaining these phenomena is the
complexity-sustainability trade-off, i.e., the tendency of the operationally
closed systems to develop excessive internal complexity that overstrains the
carrying capacity of the environment. Until now, the conceptual work along
these lines has focused on developing the systems-theoretic principles of
ecological degradation and highlighted the sustainability-enhancing role of
nonprofit organizations and corporate social responsibility. Another overarching
topic has been the analysis of connections between Luhmann’s social systems
theory and the evolutionary economics approaches, such as those of Thorstein
Veblen and Kenneth Boulding. <!--[if gte mso 9]>

Marine plastic is rapidly increasing due to increasing production and use of plastic in all economic activities, short use times and long life times of plastic, and large mismanagement of plastic waste. With this, the threat plastic poses to the marine biosphere is also increasing and will continue to increase over a long time into the future. Risk knowledge is limited and risk perception and awareness are not resulting in significant mitigation efforts. The case study will aim at modeling the use and life cycles of plastic and the transport paths that lead to plastic entering the ocean. The models will be used to simulate possible futures based on a scenario approach. The results of these efforts will be visualized with the goal to increase risk awareness.

A single resource is used with a constant rate and converted into products in use. After a while, these products become unusable because of aging. The recycling of these unusable products is imperfect, thus the amount of not recyclable resource grows (until a better recycling process is invented).

This model was designed from the SIR model(susceptible, infected, recovered) to determine the effect of the covid-19 outbreak on economic outcomes via government policy.
Assumptions
The government policy is triggered when the number of infected is more than ten.
The government policies will take a negative effect on Covid-19 outbreaks and the financial system.
Adjusted parameter: Immunity loss rate can be changed from vaccination rate.
Government policy's parameters
Adjusted parameters: Testing rate(from 0.15 to 0.95), vaccination rate(from 0.3 to 1), travel ban(from 0 to 0.9), social distancing(from 0.1 to 0.8), Quarantine(from 0.1 to 0.9)
Economic's parameters
Fixed parameter: Tourism
Adjusted parameter: Economic growth rate(from 0.3 to 0.5)
Interesting insight
An increased vaccination rate and testing rate will decrease the number of infected cases and have a little more negative effect on the economic system. However, the financial system still needs a long time to recover in both cases.
Capitalism is in crisis and climate
change disruption is now beginning to hit the bottom line. Insurance companies
know this well. According to a report by the Bank of England, insured losses
have risen from $10 000 million in 1985 to $50 000 million in 2015. Climate change
cannot be reversed, and extreme weather events
will undoubtedly get worse in the future strengthening the disruptive effects
shown in the CLD. Another dynamic is that
companies will continue to automate and, as The Economic Policy Institute has shown,
fail to reflect productivity gains in workers' salaries. The result, stagnating
salaries is disastrous for demand, given that capitalism needs endlessly rising demand
and consumption. A further serious problem is that as climate change gets worse
there will be increasing demands for companies to assume their responsibility and
bear the costs of negative externalities. The CLD shows these factors which are likely
to lead to the collapse of the system: when capitalism can no longer generate 'capital'
it has stopped to serves any useful purpose.
No economy can function well without adequate funding and in the absence of finance will eventually fall into recession. Funds (financial assets in the model) are primarily injected through investments. This is certainly true for investments and payments undertaken by the government but also for private investments via bank loans. Net exports (i.e.trade surpluses) also represent an injecton of financial assets into the economy. By contrast financial assets are taken out of the economy through taxation, the repayment of bank loans and the running of a negative trade balance. Also, if the population in aggregate decides to save more this has the effect as if money were taken out of the economy. I have deliberately avoided specifying where the funds for treasury payments and public investments come from, as this is controversial. Modern Monetary Theory, for instance, says that these funds are not provided through tax revenue. Austerity can be seen as a process that deliberately diminishes or takes out financial assets from the economy through taxation, restrictions on bank loans or cutbacks in payments and public spending by the government. It is probably useful to look at insights 2740 and 2741 before examining this CLD because they provide the context and purpose for net public spending and investment.
