Banks expand their lending, which in this model leads to higher production, wages and spending. The result is an increase in total spending.

Opportunity makes Thieves
Hanns-Jürgen Hodann
The Causal Loop Diagram on the left indicates that the number of crimes will increase rapidly as the opportunities to commit them increases. This suggests that the introduction of a negative feedback loop aimed at diminishing opportunities for committing crimes is an appropriate measure to improve the situation. A number of remedial mesures tailored to specific situations are contained in the report. A generally effective means must be the use of law and regulations that were also mentioned in the report.

Economy and Oil
Hanns-Jürgen Hodann
The recent moratorium on deep-sea drilling will reduce the supply of oil. But the world-wide trend is an ever increasing demand for it. This simple CLD tries to illustrate the dampening effect on demand and on economic activity of diminishing oil supplies and of rising prices: oil prices affect virtually all products and especially agricultural production. As it becomes more and more difficult to extract oil, prices must rise. At the moment the global recession counteracts this effect, but the recession will not last forever. Is it too early to speak of Peak Oil?

Government Spending (Current Practice)
Hanns-Jürgen Hodann
Government Spending at a certain point leads to spending in excess of tax receipts. This will automatically lead to the issue of treasuries in the belief that the excess spending must be financed by borrowing (although the government has the capacity to create money). This in turn will increase the national debt.
Consequences that follow from this practice:
1) That national debt increases whenever the government spends in excess of tax receipts.
2) That the government must pay interest on the debt issued, which in turn increases and reinforces the need for government spending.
3) That the interest paid on treasuries will increase private sector income.
There is an alternative view, supported by Modern Monetary Theory, of how government spending can proceed. Please see this Insight:

Fallacy of Spending Cuts
Hanns-Jürgen Hodann
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.

Also, experiment with the start date of a low birth-rate, environmentally focused policy.
