In a simple agent-based model of a small oligopoly nonrenewable natural resource model, the agents, communicating solely through the market price, sometimes exhibit collusion-like behavior, sometimes Cournot-like behavior. The collusion-like behavior is shown to arise when di erences between the agents are small. Conversely, the Cournot-like behavior is shown to result from di erences in produc...

This paper re-examines the Hotelling model of optimal nonrenewable resource extraction in light of stock effects and technological progress. We assume functional forms for cost and demand so that the solution to the Hotelling problem is a steady-state consistent with the empirical observation that the growth rates of market prices have remained zero over a long period of time. We use data on 14...
