Modern industrial civilisation has created massive
interdependencies which define it and without which it could not function. We all
depend on industrial farming to produce the food we eat, we depend on gasoline
being available at the gas station, on the
availability of electricity and even on the bread supplied by the local baker. Naturally,
we tend to support the institutions that supply the amenities and goods to
which we have become accustomed: if we get our food from the local supermarket,
it is likely that we would be opposed to it’s closure. This means that the economic
system that relies on continuous growth enjoys implicit societal support and that
nothing short of environmental disaster or a shortage of essential raw
materials will impede it’s growing indefinitely. It is not hard to work out the
consequences of this situation!

DRAFT IPA of Jim Webb POTUS candidate economic policy
In CIV4 a City's Health stock is a flourishing yet complex condition which acts as a City attribute intended to limit growth. Positive and negative feedback impacts City Health flow and derives from many sources: city's site, buildings, wonders, civics, resources, population, etc.
What drives this flow? When a cities unhealthiness is greater than its health limit, then for each point of population above the health limit consumes 3 food apiece rather than the standard 2 pieces. This further depletes city resources leading to starvation. In addition the city’s health also affects the rate at which it accumulates food.
For example: too much growth causes overpopulation which leads to an unhealthy city. This unhealthy city leads to less food accumulation thereby resulting in starvation which further compounds the cities unhealthiness.

This
paper aims at describing a case where system dynamics modeling was used to evaluate
the effects of information and material supply lead-time variation on sales
contributions margins and operating cash conversion cycle of a commodity export
business. An empirical dynamic model,
loaded with econometric theory of price effect on competitive demand, was used
to describe the input data. The model simulation
outputs proved themselves relevant in analyzing the complex interconnections of
multiple variables affecting the
profitability in a commercial routine, supporting the decision process among
sales managers.
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]>

One of the Archetypes that I see is the way out. The Pioneer Seeds bought will directly keep affecting DuPont's Profit until they start buying Ghanaian corn seeds. My Behavior over Time graphs keep disappearing so, I will just explain them instead. DuPont's Profit will keep going up because so many people like buying the pioneer seeds. Soil Erosion will also go up because there will be more plants growing. Farmers profit will go down because more and more farmers are buying the Pioneer seeds. Affordability of Pioneer Seeds is also going down because of there popularity. The amount of GMO labels is also going down because DuPont feels like it will risk there business. The amount of Pioneer Seeds bought is going up because more and more people keep buying them. The amount of Farming Jobs are going up because more and more people think they will get profit in this business and then it starts to stabilize and goes down a little because they realize farming isn't that good. The amount of Pioneer Seeds is affecting how big the harvest is so, the Harvest is going up. The Amount of Ghanaian Seeds bought is going down because there are more and more Pioneer seeds being bought. Dependency on DuPont is increasing because they need there Pioneer Seeds.
Also my story mode isn't working so sorry about that, but my dad couldn't figure it out either.
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.
Clone of Pesticide Use in Central America for Lab work
This model is an attempt to simulate what is commonly referred to as the “pesticide treadmill” in agriculture and how it played out in the cotton industry in Central America after the Second World War until around the 1990s.
The cotton industry expanded dramatically in Central America after WW2, increasing from 20,000 hectares to 463,000 in the late 1970s. This expansion was accompanied by a huge increase in industrial pesticide application which would eventually become the downfall of the industry.
The primary pest for cotton production, bol weevil, became increasingly resistant to chemical pesticides as they were applied each year. The application of pesticides also caused new pests to appear, such as leafworms, cotton aphids and whitefly, which in turn further fuelled increased application of pesticides.
The treadmill resulted in massive increases in pesticide applications: in the early years they were only applied a few times per season, but this application rose to up to 40 applications per season by the 1970s; accounting for over 50% of the costs of production in some regions.
The skyrocketing costs associated with increasing pesticide use were one of the key factors that led to the dramatic decline of the cotton industry in Central America: decreasing from its peak in the 1970s to less than 100,000 hectares in the 1990s. “In its wake, economic ruin and environmental devastation were left” as once thriving towns became ghost towns, and once fertile soils were wasted, eroded and abandoned (Lappe, 1998).

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.
