Abstract
The Marx model for the profit rate r depending on the exploitation rate e and on the organic composition of the capital k is studied using a dynamical approach. Introducing a discrete dynamical system in the model and supposing that both k and e depend on the profit rate of the previous cycle we get a discrete dynamical system for r, , which is a family of unimodal maps depending on the parameter a, where a is the exploitation rate at profit zero. It is interesting to note that the model can model the phenomenon known as Kondratiev waves in economic systems.
