Consistent Expectations Equilibria and Complex Dynamics in Renewable Resource Markets

Price fluctuations under adaptive learning in renewable resourcemarkets such as fisheries are examined. Optimal fisherymanagement with logistic fish pOpUlation growth implies a backward-bending, discounted supply curve for bioeconomicequilibrium sustained yield. Higher discount rates bend supplybackwards more to generate multiple steady state rationalexpectations equilibria. Under bounded rationality adaptive learningof a linear forecasting rule generates steady state, 2-cycle as weIl as chaotic consistent expectations equilibria (CEE),which are self-fulfilling in sample average andautocorrelations. The possibility of "learning to believe in chaos"is robust and even enhanced by dynamic noise.
