Chaos occurs in a nonlinear cobweb model with normal demand and supply, nai
ve expectations and adaptive production adjustment. The model differs from
existing ones in that it includes adaptive production adjustment instead of
adaptive expectations. The model exhibits observable chaos (strange attrac
tors) as well as topological chaos (horseshoes) associated with homoclinic
points. As numerical simulations show, the faster suppliers adjust their pr
oduction and the more inelastic demand is, the more likely the market behav
es chaotically. (C) 2000 Elsevier Science B.V. All rights reserved.
