This is a stock-flow consistent model, namely the simplest (SIM) model with government money. I have added imports and exports and an exchange rate which has an influence on consumption demand via real disposable income and real foreign demand.

(I had to change the equation for consumption demand. The disposable income now enters with a time lag of one period. Otherwise the model would be recursive and would not work in Insight Maker. Thanks to Gene for support.)

This is a stock-flow consistent model, namely a modified version of the simplest (PC) model with money and boonds.

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.

New Learning tend to reduce Outdated Thinking, Communicating & Learning though our Outdated Thinking, Communicating & Learning inhibits new learning. The question is then how do we break this cycle. Adopted from "An Introduction to Systems Thinking with STELLA" by Barry Richmond.

Based on Gene's Enabling a Better Tomorrow Map IM-2879 this is a Specific Health Care version based on the archived Systemswiki Health Care material. The focus is on Models and Simulation . I am following Gene's  Adventures in Wonderland framework. Advanced WIP in IM-57331

This is the Project Challenge in the Insight Maker Essentials lesson on Kumu. This lesson was developed by Gene Bellinger. I developed this relationship diagram as I was following along watching Gene introduce Insight Maker.

The following is a cross between the Lotka-Volterra Predator-Prey model from the Insight Maker manual  (https://insightmaker.com/node/3801) where the Moose represent problem symptoms, the Wolves represent temporary solution, and the addiction loop from Gene Bellinger's Addiction Archetype (https://insightmaker.com/insight/25461/Addiction-Archetype) is added.
