M or M(t) means the whole monetary Mass, the sum of all unit coins within the community at the date "t". N or N(t) mean the total of registered users inside the community at the date "t". The parameter "c" is used as the % of monetary mass growth per time unit (ex : % per year or % per month).
The rules (for the development standard) are defined as a time function UD(t), defined following Relative Money Theory (TRM in french) as a differential dividend : The quantitative dividend must change with only differential (small) adds, reaching in relative amount "c" for the average long term growth.
Where "t" is the past month. UD(t) is the UD of past month. "c" is the minimal % UD growth as defined in the 4th rule. M(t) is the existing monetary mass, and N(t) is the total amount of members. All are values just before calculation of new monthly UD(t+1):
c is defined here as the quantitative average monetary mass growth based on human average life expectancy. For a 80 years average life expectancy we have:
As those rules are parameters of OpenUDC, one community can use OpenUDC with other set of rules. OpenUDC is totally independant of the rules chosen by a money community.
Because inflation is a false conclusion due to ignorance relatively to a bad unit of money because the Quantative units of money growth due to Universal Dividend is not the Relative one.
An OpenUDC community use the relative unit 1 UD, and not the quantitative 1 Q. So there is still in the money system the same number of money units N / c UD. And then the number of UD money units only depend of the number of members, and the average amount of money per member is always fixed or limited by 1 / c UD.
So inflation is not a problem in Universal Dividend money system, because there is Quantitative creation but not Relative money creation and we count in number of Universal Dividend, the Relative Unit.
Inflation is only a problem in non-free money system when some individuals create money for their own benefit and to the detriment of others, and so the problem is due to that non-free money model.
