This version 8B of the CAPABILITY DEMONSTRATION model. A net Benefit ROI has been added. The Compare results feature allows comparison of alternative intervention portfolios. Note that the net causal interactions have been effectively captured in a very scoped and/or simplified format. Relative magnitudes and durations of impact remain in need of further data & adjustment (calibration). In the interests of maintaining steady progress and respecting budget & time constraints, significant simplifying assumptions have been made: assumptions that mitigate both completeness & accuracy of the outputs. This model meets the criteria for a Capability demonstration model, but should not be taken as complete or realistic in terms of specific magnitudes of effect or sufficient build out of causal dynamics. Rather, the model demonstrates the interplay of a minimum set of causal forces on a net student progress construct -- as informed and extrapolated from the non-causal research literature. Provided further interest and funding, this basic capability model may further developed and built out to: higher provenance levels -- coupled with increased factorization, rigorous causal inclusion and improved parameterization.

The purpose of this model intends to highlight a universal expense transaction capability or financing for sustainable development proposal.

The template shown in this model uses a stock and flow diagram with relationships to three degrees of maturity and risk in a proposed offer.
An offer represents the tools which local communities can use as part of the Means of Implementation (MoI).
The variables or vectors in the model can be set as a forecast using the features within each variable or vector and stock or flow between links allows either discreet or indiscreet monitoring of a budget with this model showing cost or expenses.
Three degrees of risk are shown in the three vectors from the design strategy and vision vector.
The management decisions are defined and applied to the implementation with this tool offered as a means to monitor either discreetly or indiscreetly.
A wicked problem in any organization would be highly complex business models and lack of agility when strategy changes or new innovation models need to be introduced.

THE 2018 MODEL (BY GUY LAKEMAN) EMPHASIZES THE PEAK IN POLLUTION BEING CREATED BY OVERPOPULATION. WITH THE CARRYING CAPACITY OF ARABLE LAND NOW BEING 1.5 TIMES OVER A SUSTAINABLE FUTURE (PASSED IN 1990) AND NOW INCREASING IN LOSS OF HUMAN SUSTAINABILITY DUE TO SEA RISE AND EXTREME GLOBAL WATER RELOCATION IN WEATHER CHANGES IN FLOODS AND DROUGHTS AND EXTENDED TROPICAL AND HORSE LATTITUDE CYCLONE ACTIVITY AROUND HADLEY CELLS
The World3 model is a detailed simulation of human population growth from 1900 into the future. It includes many environmental and demographic factors.
THIS MODEL BY GUY LAKEMAN, FROM METRICS OBTAINED USING A MORE COMPREHENSIVE VENSIM SOFTWARE MODEL, SHOWS CURRENT CONDITIONS CREATED BY THE LATEST WEATHER EXTREMES AND LOSS OF ARABLE LAND BY THE ALBEDO EFECT MELTING THE POLAR CAPS TOGETHER WITH NORTHERN JETSTREAM SHIFT NORTHWARDS, AND A NECESSITY TO ACT BEFORE THERE IS HUGE SUFFERING.
BY SETTING THE NEW ECOLOGICAL POLICIES TO 2015 WE CAN SEE THAT SOME POPULATIONS CAN BE SAVED BUT CITIES WILL SUFFER MOST.
CURRENT MARKET SATURATION PLATEAU OF SOLID PRODUCTS AND BEHAVIORAL SINK FACTORS ARE ALSO ADDED
Use the sliders to experiment with the initial amount of non-renewable resources to see how these affect the simulation. Does increasing the amount of non-renewable resources (which could occur through the development of better exploration technologies) improve our future? Also, experiment with the start date of a low birth-rate, environmentally focused policy.

Based on the Market and Price simulation model in System Zoo 3, Z504. In this model the profit calculations were not realistic. They were based on the per unit profit, which does not take items not sold into account. Also the model was not very clear on profit since it was included in the total production costs and consequently in the unit costs and subsequently profit was calculated by subtracting unit costs of the market price. Thus profit had a double layer which does not make the model better accessible. I have tried to remedy both in this simplified version.

The upper
diagram shows the principal factors that have an influence on the budget
deficit and indicates what needs to be done to correct it. But this is not the
full story. The diagram below shows that
cutting public expenditure reduces aggregate demand and increases unemployment. The reduction of
aggregate demand reduces economic activity which has the effect of reducing
tax revenue. In addition, the state has to pay out funds
as there is a need for more unemployment benefit payments. The result of these austerity measures is often the opposite of their intended
purpose: they can increase rather than decrease the budget deficit.
There is
plenty of empiric evidence to show that this has happened time and time again.
For instance, a report from UNCTAD (United Nations Conference on Trade and
Development) found that between 1990 and 2000 in all the cases examined where cutbacks in public
spending and tax increases were used, the fiscal situation did not only not
improve but worsened. Despite such repeated evidence, unfortunately calls for austerity measures continue to be heard.

If private bond holdings are going down and the government is running a big deficit then the central bank has to monetize bonds equal to the deficit plus the decrease in private bond holdings. We don't show the details of the central bank buying bonds here, just the net results.

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!

Goodwin cycle IM-2010 with debt and taxes added, modified from Steve Keen's illustration of Hyman Minsky's Financial Instability Hypothesis "stability begets instability". This can be extended by adding the Ponzi effect of borrowing for speculative investment.
