Suggestion: Create market board listings to purchase an item - to help fix economy
Allow buyers to place "buying" requests for a specific amount and price through their retainers, and sellers to fulfill those requests. (Additional improvement: allow partial fulfillments for both buying and selling?)
The available information on the market board is asymmetric and provides perfect information on supply while leaving demand virtually unknown. That means that the price of goods is highly reactive only to supply.
This creates uncertainty in the market and discourages both buyers and sellers. If equivalent information were provided on demand, the supply and demand for items would tend to meet in the middle and the price of items would reflect demand as well as supply.
