ECONSIM

An agent-based economy simulator in Unity3D based on "Emergent Economies for Role Playing Games," bazzarBot, and bazzarBot2.

Features:

• Agent-based price beliefs that governs price range to in bids.
• Prices are based on cost of inputs + profit margin
• Commodity dependencies - If food is dependent on wood and there is a forest fire, the supply of wood drops and the price of food sky rockets. Non-farmers go bankrupt as a result.
  • AuctionHouse - all sellers enter their asking price and bidders buy from lowest price up.
  • Agents that go bankrupt respawn in a more lucrative profession; corollary: bankruptcy drives growth.
  • Taxes - A government collects taxes on profits, uses money to fund respawns or stimulate economy.

• death and births of agents - population grows and shrinks with economic conditions v0.4
• Banks - can make loans based on leverage ratio, create credit bubbles.
• Agent development - agents invest surplus cash to develop new production abilities to become bigger, may develop scaling overheads.
• Mergers - agents can buy competitions out.
• Foreign markets - multiple instances of auction houses with its own set of agents and its own set of commodities.
• International trades - agents can make trades in foreign markets; local markets may impose import tariffs (player's choice).
• Separate currencies - each market has its own set of currencies; inflation rate; exchange rate.
