MITRA Tapan and Fabio PRIVILEGGI (2005), "Cantor Type Attractors in Stochastic Growth Models", Working paper POLIS - Economic Series n. 48 .
J.E.L codes: C61, O41

We study a one-sector stochastic optimal growth model where production is affected by a shock taking one of two values. Such exogenous shock may enter multiplicatively or additively.A result is presented which provides sufficient conditions to ensure that the attractor of the iterated function system (IFS) representing the optimal policy, is a generalized topological Cantor set. To indicate the role of the strict monotonicity condition on the IFS in this result, examples of attractors, which are not of the Cantor type, are constructed with iterated function systems, whose maps are contractions and satisfy a no overlap property.
