Descripción
A problem encountered in the econometric estimation of dynamic models
of livestock systems is dynamic instability during simulation of models.
In the case of systems where economic decisions are involved in the
breeding and the slaughter of animals it is possible for parameters to be
obtained which generate dynamic instability. In the paper, a simple
representation of the dynamics of a livestock system is examined using
techniques of dynamic analysis. The dynamic stability of such models
depends fundamentally on the parameters determining the births and
deaths and thus the relative flows in and out of the stock of animals. In
some situations very narrow stability ranges for the values of the
parameters are observed.
