| Abstract: | This paper firstly formulates a Disequilibrium Cobweb model with multi-products and Time-delay effects.Next,a generalized difference inequality with delays is established. Based on the obtained inequality,we finally investigate the existence and stability of equilibrium of the cobweb model. |
