En el modelo intervienen varios supuestos. El primer supuesto es el de que los asalariados no ahorran. El segundo supuesto se refiere a las condiciones clásicas de equilibrio de cantidades y de valores. El tercer supuesto es que existe un mecanismo iterativo no lineal para el cálculo de precios y tasa promedio de ganancia. El caos se genera al considerar el enlace iterativo de las variables (p, ø).]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract There is chaos in a non-lineal dynamic model of input-ouput, when defined according to the endogenous variables of price (p), quantity (x), and the average rate of earnings (ø). Several pre-suppositions are taken for granted with this model. The first is that salaried workers do not have savings. The second pre-supposition refers to the classic conditions in the balance between quantity and value. The third is that a non-lineal, iterative model exists with which to calculate prices and average rate of earnings. The chaos is generated when considering the iterative link between the variables (p, ø).]]></p></abstract>
