Capitalism 10.5

Simulation project based on the General Theory of Value

General platform for simulating period circuit representations of a capitalist economy such as Marx's Schemas of reproduction, circuitist approaches, physiocracy or plain old circular flow of income.

A port of Capitalism 9.0 which was written in JavaFX. Details of the rationale and features are still hosted in the README file of that project

To contact me use [e-mail]: I haven't been able to add this to my github profile, for reasons I don't understand.

Production version

At 30 January 2022 this is now running at this experimental site

Buglist

Project 1

Too much money is allocated to industries in the distribution stage

Changes

1 February 2022

• Fixed problems with tables because jquery version was wrong
• Fixed trace display did not display all entries
• The above migrated to the live site

2 February 2022

• Improvements to trace display
• Fixed problem in the investment step, in which replenishment demand was incorrectly calculated
• The above migrated to the live site

2 february 2022 pm

• Fixed problem that project table needs to be initialized by the administrator, for all users to avail themselves of
• Began study of project 3

4 February

• Created new model 'Simulation Parameters'
  • Abstracts from 'TimeStamp' all fields that will remain constant throughout a simulation
  • A single standard parameter object is created at signup, on a per-user basis
• Created Scaffolded User Dashboard. Here the user will be able to
  • Create simulations
  • Manage existing simulations The User Dashboard replaces the project selection option

5 February

• New model debugged and tested
• Next step is to flesh out the user dashboard

6 February

• Added a form to create a new simulation
• Installed crispy with bootstrap5 (NOTE this will require a pip install in production)

7 February

• New simulation form is working, but with very primitive validation
• Next steps:
  • better information to the user about which simulation is actually running
  • switch simulation functionality
  • delete simulation functionality
  • restart simulation functionality
  • debug the actual simulations (ONLY simple reproduction is working)

7 February

• Can now switch simulations
• Next steps:
  • Test that we are returning to the latest state of the selected simulation
  • Display some information about the selected simulation
  • debug the actual simulations
  • postpone the delete and restart functionality for now?

8 February

• A halfway house: internal changes to the models implemented, but dashboard functionality now needs to be restored

8 February

• Dashboard functionality restored: user can create and switch simulations, but cannot delete, restart, download or upload yet
• We now resume work on debugging the actual projects

This version now running at www.dascapital.org

10 February

• Now working for multiple periods (with simple reproduction)
• Next steps:
  • Delete simulation
  • Restart simulation
  • Eliminate project 3 (now redundant)
  • Scaffold an about page
  • Complete the refactoring by making 'simulation' the parameter for all actions

10 February

• Added rudimentary 'about' page

11 February

• Cleaner Dashboard with delete simulation facility

12 February

• Gradually moving all the activities associated with a user, to the current_simulation of a user
• This is not quite complete, but got us to the point where we can run project 4 though we haven't fully checked the result

13 February

• Check it out: Capitalism 10.5

14 February

• price response variable incorporated, along with economy-wide profit rate. However this is not yet displayed. It is Traced, however.

15 February

• refactored to simplify comparator logic
• we now display the economy-wide data (initial capital, current capital, profit, profit rate)

17 February

• fixes to comparator logic, fixes to capital calculations

17 February

• Trace List can now select level of detail to display. Rudimentary implementation, should be done with dropdown list or spinner, but is helpful

18 February

• Debugged a fault in trade in which industries end up with less money than they should
• A good opportunity to sharpen up the Trace reporting

18 February

• This one seems to run right through without obvious error so I will migrate it to the site
• Doesn't do profit rate equalization yet (or at least if it does, I didn't verify it)
• But the Trace is much more helpful especially for bug tracking, and the logic seems to work OK

18 February

• gonna rip it up
• wiped out migrations and database, encouraged by conversation with Ambrose Andrews, and push it over to the server
• understand origins

19 February

• removed another couple of bugs in the investment algorithm.
• Project 1 now runs from start to finish of a cycle, and ends up in the same state - which is what should in fact happen
• This version installed on server and tested

20 February

• Improvements to comparator display to make changes more easily visible
• Debug price and value calculations

21 February

• More fixes to comparator display. This is needed to debug the price revaluation logic, which is still faulty
• MAJOR CHANGE: added new 'stage' M'-M to separate out revenue and investment. Renamed the early parts of 'distribute' to 'reproduce'.
• This makes it much clearer what goes on in each stage of the circuit
• As far as I can see, project 5 (Equal Profit Rate Price calculation) is now working, but we have not yet recalculated the MELT. This will be the next stage. In addition, the project 5 numbers should be made a little more realistic since the profit rate disparity between industries is rather large.
