Simulating Hyperinflation for 3650 days.

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.

See blog at http://howfiatdies.blogspot.com for more on hyperinflation, including a hyperinflation FAQ.

The macroeconomic ruel: SPENDING = INCOME = OUTPUT, WHICH DRIVES EMPLOYMENT is presented here in a schematic form. Output can be taken to be equivalent to  GDP. In order to maintain output it is necessary for all the income earned to be spent. If this is not the case, then companies find they have excess unsold stock on their hands and will cut back on production. This, in time, will lead to an increase in unemployment as companies need fewer employees. The shortfall in spending can be made up by any of the three sectors that contribute to total output. However, in cases where  a country has a trade deficit and where the private sector is not spending or investing enough, the only option is for the government to Net Spend i.e. to spend more than it collected in taxes causing a fiscal deficit.

A simple model for cc adoption which depends on several condions.

This Insight is the first in a series of models that examine the dynamics of population growth and decline in a simple environment.  It follows on from a series of four Insights that introduce the basic concepts of Systems Dynamics that start here.

The next Insight model introduces the concept of limits to growth and explores the more complex behaviour this generates.  The model can be found here. 

Circular equations WIP for Runy.

This model simulates the economics of buying a home. It was created to compare buying a home against using investment returns to pay for rent. According to Micheal Finke, house prices typically run 20x monthly rental rates. 

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.
