摘要:
The process of agricultural production is treated as a discrete process and modelled with a nonlinear cobweb recursion relation, which is a composite of production and price setting mechanisms. The various processes that result in ecological exhaustion enter the model as a nonlinearity in the production function. Under these conditions it is predicted that the trajectories of prices and production through time will generate chaotic, and thus unpredictable, patterns.
