The Middle

The monetary system of the republic gets going in 1963.

Satisfied that she understood the basic dynamics of her newly designed monetary system, governor Hill set out some operational parameters prior to the first Earthly financial quarter of 1963.

Republic Population

  • Governments = 1
  • Consumer Households = 110
  • Producer Households = 100

The 'Dwelling Security & Protection' tax was set at 37% of all consumer income.

Employment & Simplistic Consumer Agent Behaviours

A correctly assumed consumption function as follows:

  1. Proportion of disposable income: 60%
  2. Proportion of (agent wealth) at the opening of the period (quarter): 40%

In every financial quarter, each producer agent (100 in total) will receive an equal share of the republic's official expenditure (the purchasing of tea crop & other services). Each producer will subsequently employ (by random choice) one of the 110 consumer agents. A producer agent will check to see if the consumer agent is currently unemployed (has not been previously employed by another producer agent), else the random selection is repeated.

Consumer agent 'rating', that is, the approval, disapproval or ambivalence towards the government of the republic will depend on individual wealth (money equity) at the end of each financial quarter. A consumer agent will record an 'approval' rating if it has achieved a new wealth 'high' at the end of the current financial quarter. 'Ambivalence' is recorded if the agent does not achieve a new wealth 'high', but on communicating with another random consumer agent, discovers that its wealth is greater than that of the other consumer agent. 'Disapproval' is recorded when a consumer agent does not achieve a new wealth 'high' and on communicating with another random consumer agent, discovers that its own wealth is either less than or equal to that of the other consumer agent.

Expenditure Pattern

The governor made an assessment of existing system productivity and informed her officials on purchasing arrangements. Republic purchasing that is to take place on the first day of each financial quarter, she said, will match dollar for dollar, the growing government expenditure1 of Earth nation, the United States of America. No arguments; get on with it.

Time Flies

The year is 2019 and Hill wanted to better understand the dynamics of the republic's monetary system (yes, 55 years later).

Visual Output
What did the money supply look like over time? See outcomes 1 & 2
What did the macro indicators show? Are consumer agents happy with their finances? See outcomes 1 & 2

From her analysis, Hill noted two key points.

  1. Money supply as a percentage of republic income (GDP) had been erratic since inception. Money supply as a percentage of all economic activity had since the year 2010 remained consistently below 60 percent of the long-term (all-time) average figure.
  2. The percentage of consumer agents completely approving of government expenditure remained consistently (in every quarter) in the 10 to 20 percent range until Q1 1987. Since Q1 1987, consumer agent approval had regularly dipped below 10 percent, remaining consistently below 10 percent of the population since Q3 2012.


It was time to rethink republic expenditure. New challenges await.
