This is relating to a server for a game I'm setting up (the game isn't mine, but I have the ability to change all prices - buy and sell - on the server).
I could arbitrarily pick prices for all items on a server, including items that regularly produce other things that could be sold (eg. Cow cost $100, milk sells for $1, cows live forever and can be milked once per day), but I feel like I'm going to make the system unbalanced and ultimately exploitable. Is there a mathematical or scientific model that can be applied to this type of situation to determine the ideal ratio of prices between different object.
To give a bit of background, the goal is to accumulate wealth, by buying things that can be used to create other things that can be sold.
My first through was to run some sort of simulation of the game (people buy and selling things etc.) but this seems far to complex and unlikely to randomly determine the explotability of a set of prices. I'm way out of my depth here, so any suggestions would be appreciated.
