Price and Profit Dynamics

We have simulated an economy with 1000 buyers and 5 sellers employing various mixtures of pricing strategies. In each of the simulations depicted below, each buyer's valuation of the good v = 1, and each seller's production cost c = 0.5. The mixture of buyer types is set at tex2html_wrap_inline898 , i.e., 75% are bargain hunters.

The simulation is asynchronous: at each time step, a buyer or seller is randomly selected to carry out an action (e.g., buying an item or resetting a price). The chance that a given agent is selected for action is determined by its rate; the rate tex2html_wrap_inline544 at which a given buyer b attempts to purchase the good is set to 0.001, while the rate tex2html_wrap_inline550 at which a given seller reconsiders its price is 0.00002. Each simulation was iterated for 100 million time steps.
